In the figure, 1 is a car on which a person or luggage is loaded, 2 is a one-day counter for compensating for the weight of car 1, 3 is a rope that suspends car 1 and counter-weight 2, and 4 is a rope 3 A thin hoist that drives and raises and lowers the car 1 and the counter one weight 2, 4a is a hoisting machine, 5a and 5b are return wheels that change the direction of suspension of the mouthpiece 3. , 6 is the guide rail for the car, 7 is the guide rail for the counter one way, 8 is the hoistway, 1 1 is the hanging car for the car 1, 1 2 is the hanging car for the county 1 weight, 2 is the car side 14 is the counterweight side cleat.

Next, a conventional elevator apparatus will be described with reference to FIGS. 12 to 13. FIG.

The car 1 and the counterweight 2 of the elevator are moved up and down via the rope 3 suspended on the sheave 4a of the hoisting machine 4. At this time, the car guide rail 6 regulates the horizontal movement of the car 1, and the counterweight guide rail 7 regulates the horizontal movement of the power counterweight 2, thereby preventing other movement in the hoistway. Contact between equipment and hoistway walls with car 1 and counterweight 2 Prevents interference. Where basket 1 and county 1 The vertical projections of the hoisting machine 4 and the hoisting machine 4 are separated from each other, and the hoisting machine 4 is placed parallel to one adjacent wall surface.

In recent years, in order to minimize the space occupied by elevators, various types of elevator systems have been proposed in which a machine is not installed and a hoist is built in a hoistway. Specifically, (1) a method in which a thin-type hoist is arranged above the upper limit of the lift of the counterweight, and (2) a hoist in the top of the hoistway, that is, the ceiling of the car when the top floor of the car stops. (3) A method in which the hoisting machine is arranged below the bit section in the hoistway, ie, the car floor when the lowest floor of the car stops.

Of these, (1) and (2) require a higher hoistway height than the minimum required for ascending and descending the elevator every night, and the hoisting machine is mounted on a car near the top of the hoistway. The disadvantage is that it is necessary to take protective measures to prevent the maintenance worker from hitting the ceiling of the hoistway due to unexpected rise of the car. In the case of (2), the heat generated by the hoist stays at the top of the hoistway, that is, in the vicinity of the hoist itself, so that the hoist tends to break down due to temperature rise. (3) has a drawback in that a protective means is required to dispose the hoisting machine in the bit part where flooding is most likely. The elevator device of the above-mentioned Japanese Patent Application No. 9-1615172 solves the disadvantage of (1), but the total height of the hoistway above and below the vertical projection plane of the hoisting machine. This creates a new disadvantage of creating unused space over the entire area.

Embodiment 1 of the present invention relating to an elevator device will be described with reference to FIGS. 1 to 3. FIG.

FIG. 1 is a bird's-eye view of Embodiment 1 of the elevator apparatus of the present invention, and FIG. 2 is a plan view. This is an example in which the counter 8 is located behind the car when viewed from the entrance of the elevator every night, and the hoisting machine is arranged beside the car. In the figure, 1 is a car carrying a person or luggage, 2 is a counterweight that compensates for the weight of car 1, 3 is a rope that suspends car 1 and the council evening 2 and 4 is a rope 3 A thin hoist that drives and raises and lowers the car 1 and the counterweight 2. 4a is the sheave of the hoisting machine 4, 4b is the motor of the hoisting machine 4, 5a and 5b are A return car that changes the direction of suspension of robe 3, 6 is a guide rail for the cage, 7 is a guide rail for the county and one night, 8 is the hoistway, 8a is the top of hoistway 8, 8b is the hoistway 8 The pit section, 9 is the beam that supports the hoisting machine 4, 10 is the beam that supports the return wheel 5, 1 is the hoisting wheel of the car 1, 1 is the hoisting wheel of the county, one weight, 2 and 1 3 A ladder on the basket side, 14 on the counterweight side, and 15 on the control panel. What The dashed-dotted line A in Fig. 1 indicates the height of the car ceiling when the top floor of the car stops. That is, the top is above this line. The dashed line B in Fig. 1 indicates the height of the car floor when the lowest floor of the car stops. That is, below this line is the bit portion.

In the figure, the lower end of the hoisting machine 4 is above the dashed line B. That is, the hoisting machine 4 is disposed below the ceiling of the car when the top floor of the car is stopped, and the lower end is above the floor of the car when the bottom floor of the car is stopped. The hoisting machine 4 is arranged in parallel with one adjacent wall.

Further, the return wheel 5a is disposed so as to partially overlap with the hoisting machine 4 on the plane of projection of the hoistway 8 and the return wheel 5b is disposed inclined with respect to the wall surface. I have.

Further, the hoisting machine 4 is fixed to the lower side of the beam 9 supported by the car guide rail 6 and the counter one-way guide rail 7. The sheave 4 a of the hoisting machine 4 is located on the car side of the rear surface of the car guide rail 6 in the plane section of the hoistway 8. Here, the back of the guide rail refers to the portion shown in Fig. 3C. In this example, the hoisting machine 4 is directly fixed to the beam 9, but it can be mounted via an elastic body to provide a vibration-proof structure. In addition, the beam 9 and the guide rails 6 for the car and the guide rails 7 for the countdown can be attached via elastic bodies.

In addition, the return wheels 5a and 5b are fixed to the beam 10 supported by the car guide rail 6 and the counter guide rail 7 for the car. Is fixed directly to the beam 10, but may be mounted via an elastic body to provide a vibration-proof structure. In addition, the beam 10 and the guide rail 6 for the car and the guide rail 7 for the counterweight can be attached via an elastic body.

In addition, the control panel 15 has a lower end that is lower than the car floor when the lowest floor of the car is stopped. It is arranged at about the same height as the hoisting machine 4 upward.

The mouth 3 suspended on the sheave 4 a of the hoisting machine 4 driven by the control panel 15 is turned by the return wheels 5 a and 5 b, and the basket lifting wheel 11 and the counter The car 1 and the counter 10 are moved up and down via the lifting wheel 12 of the car. At this time, the car guide rail 6 and the counter one-way guide rail 7 restrict the horizontal movement of the car 1 and the counter one-way 2.

The return wheel 5a is arranged so as to partially overlap the hoisting machine 4 on the plane of projection of the plane of the hoistway 8, and the sheave 4a of the hoisting machine 4 has a car guide within the plane of the hoistway 8. Since it is located closer to the car than the back of the drain 6, the area occupied by the hoisting machine 4 on the plane of projection of the hoistway 8 is small, and the unused space over the entire height of the hoistway is reduced. I have. Further, the winding angle of the rope wound around the sheave 4a of the hoist can be made larger than 180 °, so that the traction capacity can be increased. In addition, since the hoisting machine 4 is located below the car ceiling when the top floor of the car is stopped, the inspection worker riding on the car may hit his / her head on the ceiling of the hoistway due to unexpected rise of the car. No protective measures are required. Furthermore, the heat generated by the hoist goes to the upper part of the hoistway near the ceiling, so that the hoist does not break down due to the temperature rise. Further, since the return wheel 5b is inclined with respect to the wall surface of the hoistway 8, the angle of entry of the rope 3 into the rope groove of the sieve 4a is reduced, and damage to the rope is prevented.

In addition, the hoisting machine 4 is installed under the beam 9, and the return wheels 5 a and 5 b are installed on the beam 10, so that the cage guide rail 6 and the counter way are provided via the beam 9. The upward force due to the tension of the rope 3 acting on the guide rail 7 for the car and the tension of the rope 3 acting on the guide rail 6 for the car and the guide rail 7 for the counterweight via the beam 10 The downward force of the building offsets inside the guide rail, reducing the force on the building.

Furthermore, since the lower end of the hoisting machine 4 and the lower end of the control panel 15 are above the car floor when the lowest floor of the car is stopped and below the car ceiling, even if the bit is submerged, they will be damaged. There is nothing.

In this type of elevator system without a machine room, the pit depth is about 1.2111 to 1.5 m, and the hoisting machine and the control panel are located at this position. Is within reach of the worker when standing on the pit floor, for example, within a range of 1.2 m to 1.7 m in height (from the car floor when the car is at the lowest floor to 1 m from the pit floor). 7 m height), making inspection work easy. If the lower end of the hoisting machine 4 and the lower end of the control panel 15 are located above the car floor when the car is on the first floor and below the car ceiling, not only the pit but also the entire basement floor will be flooded. However, the hoist 4 and the control panel 15 are not damaged.

If the lower end of the hoisting machine 4 is located above the car floor when the car standard floor is stopped and below the car ceiling, and the control panel 15 is placed at approximately the same height, the operation of the elevator will be immediately controlled. Inspection is the easiest to do. If the lower end of the hoisting machine 4 is located above the car floor when the top floor is stopped and below the ceiling of the car, the height of the hoisting machine 4 and the return wheels 5a and 5b will be close. It is convenient to check both.

In addition, by integrating the beams that support both, it is possible to save material and reduce space.

Example 2.

Second Embodiment A second embodiment of the present invention relating to an elevator apparatus will be described with reference to FIGS.

FIG. 4 is an overhead view of Embodiment 2 of the elevator apparatus of the present invention, and FIG. FIG. This is an example in which the counter gate is located behind the car when viewed from the entrance of the elevator every night, and the hoisting machine is placed beside the elevator space of the counter gate. In the figure, the same reference numerals as those in the above-mentioned figures denote corresponding parts, and the description is omitted.

In the figure, the lower end of the hoisting machine 4 is above the dashed line B. That is, the hoisting machine 4 is arranged below the ceiling of the car when the top floor of the car is stopped, and the lower end is above the floor of the car when the bottom floor of the car is stopped. Further, the hoisting machine 4 is arranged in parallel with one adjacent wall. ·

Further, the return wheels 5 a and 5 b are arranged so as to partially overlap with the hoisting machine 4 on the plane of projection of the hoistway 8. Further, since the return wheel 5b is inclined with respect to the wall surface of the hoistway 8, the angle of entry of the rope 3 into the rope groove of the sieve 4a is reduced, thereby preventing damage to the rope.

Furthermore, in the _c present example that secure the lower side beam 9 which is supported a卷上machine 4 by-car guide Doreru 6 and the counter one-wait for Guy Doreru 7, the卷上machine 4 to the beam 9 Although it is directly fixed, it can also be attached via an elastic body to provide a vibration isolation structure. In addition, the beam 9 and the guide rails 6 for the car and the guide rails 7 for the counter light can be attached via an elastic body.

Further, the return wheel 5 is fixed to the beam 10 supported by the car guide rail 6 and the counter one-way guide rail 7. In this example, the return wheel 5 is directly fixed to the beam 10, but it may be mounted via an elastic body to form a vibration-proof structure. In addition, the beam 10 and the car guide rail 6 and the counterweight guide rail 7 can be attached via an elastic body.

Furthermore, the control panel 15 is disposed immediately above or immediately below the hoisting machine 4 in the plane section of the hoistway 8 where the projection plane overlaps with the hoisting machine 4. The mouth 3 suspended on the sheave 4 a of the hoisting machine 4 driven by the control panel 15 is turned by the return wheel 5, and the car hanging wheel 11 and the county-height hanging wheel Raise / lower car 1 and counter 1/2 via 1 2. At this time, the car guide rail 6 and the count evening guide rail 7 restrict the horizontal movement of the car 1 and the count evening 2.

The return wheel 5 a is arranged so as to partially overlap with the hoisting machine 4 on the plane of projection of the hoistway 8, and the control panel 15 overlaps with the hoisting machine 4 in the plane of the hoistway 8. Since the hoisting machine 4 is arranged immediately above or immediately below, the area occupied by the hoisting machine 4 on the projection plane of the plane section of the hoistway 8 is small, and the unused space over the entire height of the hoistway is reduced. In addition, since the hoisting machine 4 is located below the car ceiling when the top floor of the car is stopped, there is a risk that the inspection worker riding on the car will hit the ceiling of the hoistway due to unexpected rise of the car. No protective measures are required. Furthermore, since the heat generated by the hoist goes to the upper part of the hoistway near the ceiling, the hoist does not break down due to the heat.

In addition, the hoisting machine 4 is installed under the beam 9, and the return wheels 5 a and 5 b are installed on the beam 10, so that the cage guide rail 6 and the counterweight are provided via the beam 9. Upward force due to the tension of the rope 3 acting on the guide rail 7 for the car, and downward force due to the tension of the rope 3 acting on the guide rail 6 for the car and the counter one-way guide rail 7 via the beam 10 Cancel each other out inside the guide rail, reducing the force on the building.

Furthermore, the lower end of the hoisting machine 4 is above the car floor when the lowest floor of the car is stopped and below the car ceiling, and the control panel 15 is a hoisting machine whose projection surface is a flat section of the hoistway 8. Since the pit is flooded and immediately adjacent to the position 4, the hoist 4 and the control panel 15 are not damaged even if the pit is flooded. In this type of elevator without a machine room, the depth of the pit is

It is about 1.2 m to 1.5 m, and if the hoist is located at this position, the reach of the worker when standing on the bit floor, for example, 1.2 m to 1.7 m The height is within the range of m height (from the car floor when the lowest floor of the car is stopped to the height of 1.7 m from the pit floor), making inspection work easy.

The lower end of the hoisting machine 4 is located above the car floor when the car is stopped on the first floor and below the car ceiling, and the control panel 15 overlaps the hoisting machine 4 in the plane section of the hoistway 8. If it is placed immediately above, the hoist 4 and the control panel 15 will not be damaged even if the entire basement floor is flooded, not just the pit.

Also, the lower end of the hoisting machine 4 is located above the car floor when the car standard floor is stopped and below the car ceiling, and the control panel 15 overlaps the hoisting machine 4 in the plane section of the hoistway 8. If it is located immediately above or immediately below, it is easiest to perform inspections in accordance with the operation management of the elevator every night.

When the lower end of the hoisting machine 4 is above the car floor when the top floor is stopped and below the ceiling of the car, the height of the hoisting machine 4 and the return wheel 5 are close to each other. It is convenient for checking.

Example 3.

Third Embodiment A third embodiment of the present invention relating to an elevator apparatus will be described with reference to FIGS. 6 to 7 and FIG.

FIG. 6 is an overhead view of Embodiment 3 of the elevator apparatus of the present invention, and FIG. 7 is a plan view. This means that the elevator is on the side of the car when viewed from the elevator entrance, and the hoist is on the same side of the car as the counterweight, and the counterweight is on the flat side of the hoistway. If the projection planes overlap on the cross section This is an example where they are not arranged. In the figure, the same reference numerals as those in the above-mentioned figures denote corresponding parts, and a description thereof is omitted.

In the figure, the lower end of the hoisting machine 4 is above the dashed line B. That is, the hoisting machine 4 is disposed below the ceiling of the car when the top floor of the car is stopped, and the lower end is above the floor of the car when the bottom floor of the car is stopped. Further, the hoisting machine 4 is arranged parallel to one adjacent wall.

Further, the return wheel 5 a is disposed so as to partially overlap the hoisting machine 4 on the plane of projection of the hoistway 8. In addition, since the return wheels 5a and 5b are inclined with respect to the wall of the hoistway 8, the angle of entry of the rope 3 into the opening groove of the sheave 4a is reduced, thereby preventing damage to the rope. I have.

Further, the hoisting machine 4 is fixed from below to the beam 9 supported by the car guide rail 6 and the counter one-way guide rail 7 <The motor 4 b of the hoisting machine 4 is It is located closer to the car than the back of the car guide rail 6 in the plane section of the car. Here, the back surface of the guide rail is the portion C in FIG. In this example, the hoisting machine 4 is directly fixed to the beam 9, but it is also possible to mount the hoisting machine 4 via an elastic body to form a vibration-proof structure. Also, the beam 9 and the guide rail 6 for the car and the guide rail 7 for the countdown can be attached via an elastic body.

In addition, the return wheel 5 is fixed to the beam 10 supported by the car guide rail 6 and the counterweight guide rail 7. In this example, the return wheel 5 is directly fixed to the beam 10, but it may be mounted via an elastic body to form a vibration-proof structure. In addition, the beam 10 and the car guide rail 6 and the counterweight guide rail 7 can be attached via an elastic body.

The rope 3 suspended on the sheave 4 a of the hoisting machine 4 driven by the control panel 15 is turned by the return wheel 5, and the car suspension wheel 11 and the counter — Raise / lower car 1 and counter 1 weight 2 via weight suspension wheel 1 2. At this time, the car guide rail 6 and the counterweight guide rail 7 restrict the horizontal movement of the car 1 and the counterweight 2.

The return wheel 5a is arranged so as to partially overlap with the hoisting machine 4 on the projection plane of the plane of the hoistway 8 and the motor 4b of the hoisting machine 4 is used for cars in the plane of the hoistway 8 Since it is located closer to the car than the back of the guide rail 6, the area occupied by the hoisting machine 4 on the plane of projection of the hoistway 8 is small, and the unused space over the entire height of the hoistway is reduced. I have. In addition, since the hoisting machine 4 is located below the car ceiling when the top floor of the car is stopped, there is a risk that the inspection worker riding on the car may hit the ceiling of the hoistway due to unexpected rise of the car. There is no. Furthermore, since the heat generated by the hoist goes to the upper part of the hoistway near the ceiling, the heat does not damage the hoist.

Also, the hoisting machine 4 is installed under the beam 9, and the return wheels 5a and 5b are installed on the beam 10. Therefore, through the beam 9, the cage guide rail 6, the county An upward force due to the tension of the rope 3 acting on the guide rail 7 for the weight, and a downward force due to the tension of the rope 3 acting on the guide rail 7 for the car and the counterweight 7 via the beam 10. The forces offset each other inside the guide rails, reducing the forces on the building.

Furthermore, since the lower end of the hoisting machine 4 and the lower end of the control panel 15 are above the car floor when the lowest floor of the car is stopped and below the car ceiling, even if the pit is flooded, the hoisting machine 4 and control panel 15 are not damaged.

In this type of elevator device without a machine room, the pitch of the pitch is approximately 1.2 m to 1.5.5 m, and the hoisting machine and the control panel are arranged at this position. Is within reach of workers when standing on the bit floor, for example This is within the range of 1.2 m to 1.7 m height (1.7 m above the floor of the car when the lowest floor of the car is stopped to the bit floor), making inspection work easy. If the lower end of the hoisting machine 4 is higher than the car floor when the car is stopped on the first floor and the upper end is lower than the car ceiling, and the control panel 15 is located at almost the same height, The hoisting machine 4 and control panel 15 will not be damaged even if the entire basement floor is flooded.

If the control panel 15 is placed at approximately the same height with the lower end of the hoisting machine 4 above the car floor when the car standard floor is stopped and the upper end below the car ceiling, It is easiest to perform inspections that are in line with the operation management.

If the lower end of the hoisting machine 4 is above the car floor when the uppermost floor is stopped and the upper end is below the car ceiling, the hoisting machine 4 and the return wheel 5 are close to each other. It is easy to adjust the position of both, and it is convenient for inspection.

Example 4.

Fourth Embodiment A fourth embodiment of the present invention relating to an elevator apparatus will be described with reference to FIGS. 8 to 10. FIG.

FIG. 8 is an overhead view of Embodiment 4 of the elevator apparatus of the present invention, FIG. 2 is a plan view, and FIGS. 9 and 10 show main parts. This is because the counter is at the back of the car as seen from the elevator entrance, and the car is returned to the side of the car and just below the height of the car ceiling when the top floor stops. This is an example where it is arranged below a beam to be supported. The same reference numerals as those in the above-mentioned figures denote corresponding parts, and a description thereof is omitted.

In the figure, 16 is an elastic body that absorbs the vibration of the beam 10. Here, the inclination angle of the return wheel 5 with respect to the hoistway wall is variable, and the interval between the two return wheels 5 is also variable. This variable structure can be realized, for example, by fastening the beam 10 and the frame of the return wheel 5 with bolts and making the fastening holes elongated. However, the variable structure is not limited to this. Also, this The modified structure is also applicable to the first to third embodiments.

Since the hoist 4 is mounted below the beam 10 supporting the return wheel 5, the tension acting on the rope 3 causes the upward force acting on the sheave 4a of the hoist 4 and the return wheel 5 Since the force acting on the beam 10 is offset by the force acting downward on the beam 10 as an internal force, the force acting on the guide rail is reduced, and O o

In addition, since the hoisting machine 4 and the return wheel 5 are mounted on the same beam 10, mutual positional adjustment is easy.

Further, the hoisting machine 4 and the return wheel 5 are mounted on the same beam 10, and the beam 10 is connected to the guide rail 6 of the car and the guide rail 7 of the kayak weight via the elastic body 16. The vibration of the hoist 4 and the return wheel 5 can be effectively insulated.

Further, since the inclination angle of the return wheel 5 with respect to the hoistway wall is variable, and the interval between the two return wheels 5 is also variable, the car 1 of different size, the hanging wheel of the car 12 and the counter 1 The same design can cope with a change in the positional relationship of the weight with the hanging wheel 13 in the plane of the hoistway.

By replacing one of the two return wheels 5a and 5b with a drive unit 17 and driving it synchronously with the hoisting machine 4, the drive capacity can be improved, and a large-capacity elevator device can be used. Can also respond. Since the elevator apparatus according to the present invention is configured as described above, the following effects can be obtained.

In the elevator apparatus according to the present invention, the elevator car moves up and down in the hoistway, the elevator car moves in the opposite direction to the elevator car, a car guide rail that regulates the horizontal movement of the car, A counterweight guide rail for restricting the horizontal movement of the counterweight, a rope for suspending the cage and the counterweight, and a rope wound around the hoistway. An elevator having a hoist that lifts and lowers the car and the power train via a rope, wherein the hoist is thin and the car at the lowest floor stop of the hoistway is stopped. At a position above the floor surface and below the car ceiling when the top floor is stopped, it is placed parallel to one of the walls in the plane section of the hoistway, and the car ceiling when the top floor of the hoistway is stopped. Above, the area occupied by the hoist on the plane of projection of the hoistway is small. The space used has been reduced. In addition, since the angle at which the rope enters the rope groove of the hoisting machine is small, damage to the rope can be prevented.

Also, since at least one of the hoist and the return wheel is fixed to the beam supported by the car guide rail or the counter guide rail, the tension of the rope causes The upward force acting on the hoist and the downward force acting on the return wheel cancel each other inside the guide rail, reducing the force acting on the building.

Further, since the lower end of the hoist is arranged above the car floor when the lowest floor of the hoistway is stopped, the hoist is not damaged even if the pit is flooded. Absent.

Furthermore, the lower end of the hoist is arranged above the floor of the first floor. Therefore, even if the underground floor is flooded, the hoist will not be damaged.

Further, since the winding machine is arranged above the reference floor, the inspection suitable for the operation of the elevator is easy.

Further, since the hoist is disposed above the top floor, the position adjustment between the return wheel and the hoist is easy, which is convenient for inspection.

Further, since the hoist is attached to the lower side of the beam supporting the return wheel, the force acting on the guide rail can be reduced. In addition, it is easy to adjust the position between the return wheel and the hoist, which is convenient for inspection.

Further, since the beam supporting the return wheel and the beam in which the hoist is attached to the lower side has an anti-vibration structure, vibration between the hoist and the return wheel can be effectively insulated.

Furthermore, since at least a part of the hoist and the return wheel are overlapped on the plane of projection of the hoistway, the hoistway space can be reduced. Further, since the sheave or the motor of the hoist protrudes from the rear surface of the guide rail to the car side in the plane section of the hoistway, the space of the hoistway can be reduced.

Further, since a control panel for controlling the drive of the hoisting machine is arranged at almost the same height as the hoisting machine or directly above or immediately below the hoisting machine, the hoisting machine and the control board Inspection is easy.

Further, since the lower end of the control panel is disposed above the car floor when the lowest floor of the hoistway is stopped, the control panel is not damaged even if the pit is flooded.

Further, since the lower end of the control panel is disposed above the first floor of the hoistway, the control panel is not damaged even if the basement floor is flooded.

Further, since one of the return wheels is used as a driving device, it can be applied to a large-capacity elevator. Furthermore, since the inclination angle of the return vehicle with respect to the hoistway wall surface is variable, or the arrangement distance of the return vehicles in the plane section of the hoistway is variable, the size of the car is small. Even if they are different, they can be handled with the same design. Industrial applicability
