BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a continuous vertical transfer device suitable as a device for transferring excavated earth and sand to a high place such as on the ground mainly at an underground excavation work site, and more particularly, a boat type connected at appropriate intervals. The transport container is circulated and rotated in a Z-shaped circulation path that is composed of a lower horizontal path that constitutes the transported object input section, an upper horizontal path that configures the transported object discharge section, and a vertical path that connects both horizontal paths. The present invention relates to a continuous vertical transfer device.

[0002]

2. Description of the Related Art As shown in FIG. 8, a continuous vertical conveying apparatus of this type has an ascending path from an upper horizontal path portion 1a of a lower horizontal path 1 to a vertical path 2 in a Z-shaped circulation path. Upper horizontal path section 3 of upper horizontal path 3 via section 2a
The route to a is defined as a transport route portion in which the boat-shaped transport containers 4 connected at appropriate intervals move while maintaining a horizontal upright posture, and the lower horizontal route 1 which is the starting end position of this transport route portion.
The upper horizontal path portion 1a of the above is used as the transferred object loading portion 5, and the container reversal path portion from the leading end turn portion 3b of the upper horizontal path 3 which is the end position to the lower horizontal path portion 3c is used as the transferred material discharging portion 6. However, in the conventional continuous transfer device of this type, the transfer container 4 is rotated 180 degrees at the tip turn portion 1b of the upper horizontal path 3 to change to a horizontal inside-out posture, so that the transfer target in the transfer container is transferred. It was designed to force objects to be released by gravity.

In the case of dry powdery or granular materials such as grains,
The transported object in the transport container 4 is almost completely discharged by simply rotating the transport container 4 by 180 degrees at the tip turn portion 1b of the upper horizontal path 3 to change it to the horizontal upside down posture, but the transported object is underground. In the case of clay-like mud earth and sand with high water content and high viscosity, such as excavated earth and sand, it is not completely discharged by simply inverting the transfer container 4 upside down, and a large amount of earth and sand in the container. There is a high possibility that will adhere and remain. When such clay-like muddy earth and sand adheres and remains in the container, the residue in the container moves due to gravity or gravity in the path portion where the empty transfer container 4 moves in the horizontal upside down posture or the vertical posture. It may slide down due to vibration, and may be attached to a drive chain (in the conventional example shown in FIG. 8, drive chains 7 and 8 also serving as container attitude control) or a guide rail that circulates and drives the transport container 4, causing a failure, Even if it is not so, it is fully conceivable that finally the sediment deposited in the case containing the container circulation path will cause the same failure.

It is desirable to use the groove-shaped guide rail 26B, but in this case, the guide rollers 20a, 2
Since the moving path of 0b and the moving paths of the drive chains 15a and 15b (moving loci of the support arms 21a and 21b) intersect, the guide rollers 19a and 19b inside the front end in the first half.

In the continuous vertical transporting device constructed as described above, the drive toothed wheel 14 is rotationally driven by the motor 16 in a predetermined direction to rotate the drive chains 15a and 15b, whereby each transport container 4 is moved. However, from the upper horizontal path portion 1a of the lower horizontal path 1 to the ascending path portion 2a of the vertical path 2, the upper horizontal path portion 3a of the upper horizontal path 3, the tip turn portion 3b, the lower horizontal path portion 3c, and the vertical path 2 descending. The Z-shaped circulation path is rotated so as to pass through the path portion 2b, the lower horizontal path portion 1b of the lower horizontal path 1, and the tip turn portion 1c in this order. At this time, the transport container 4 is driven by the drive chains 15a, 1
5b, it is suspended swingably around horizontal support shafts 23a and 23b, but as shown in FIG. 5, in the upper horizontal path portion 1a of the lower horizontal path 1, the container attitude control means 28 is provided. All the guide rollers 19a to 20b are supported by the guide rails 27 and horizontally move while being held in the horizontal upright posture, and in the turn portion of the vertical path 2 to the ascending path portion 2a, the inside of the groove-shaped guide rail 26B is moved backward. The guide rollers 20a and 20b on the outer side of the ends are held in a horizontal upright posture by moving, and in the ascending path portion 2a of the vertical path 2, the guide rails 25A and 26 of the container attitude control means 30.
When A contacts the inside of each of the guide rollers 19a to 20b, it moves upward while being held in a horizontal upright posture.

As shown in FIG. 6, in the turn portion of the subsequent upper horizontal path 3 to the upper horizontal path portion 3a, the guide rollers 20a, 20 on the outer side of the rear end inside the grooved guide rail 26B.
By moving b, the transport container 4 is continuously held in the horizontal upright posture, and in the upper horizontal path portion 3a, all the guide rollers 19a to 20b are supported by the guide rails 27 of the container posture control means 35 and are horizontally oriented. It moves horizontally while being held in an upright position. After that, as shown in FIG. 7, when the transport container 4 moves on the transported object discharge portion 6 extending from the tip turn portion 3b to the lower horizontal path portion 3c, the guide rails 26A and 27 and the container attitude control means. Each of the guide rollers 19a to the grooved guide rails 25B and 26B of 37
20b is guided to change from a horizontal upright posture to a vertical posture rotated by 90 degrees, and after moving a certain distance in this vertical posture, it is further rotated so that the front end precedes to become a horizontal inside-out posture. , The lower horizontal path 3c as it is
It is inherited by the guide rail 27 of the container attitude control means 36.

As shown in FIG. 6, the transport container 4 which moves in a horizontal upside down posture is provided with a groove guide rail 25.
The guide rollers 19a to 20b are sequentially guided to B and 26B, and rotate from the upside down posture to the horizontal upright posture again,
As it is, it enters the descending path portion 2b of the vertical path 2. The transport container 4 on the descending path portion 2b is the container attitude control means 3
The guide rails 25A and 26A of No. 1 are attached to the respective guide rollers 19
By coming into contact with the insides of a to 20b, it moves downward while being held in a horizontal upright posture.

From the lower end of the descending path portion 2b to the lower horizontal path 1
The transport container 4 that moves to the lower horizontal path portion 1b of the container is controlled by moving the guide rollers 20a and 20b on the outer side of the rear end inside the groove-shaped guide rail 26B of the container attitude control means 32.
The lower horizontal path portion 1b while changing to a tilted posture of falling forward
After entering the inside and maintaining the tilted posture for a certain distance,
It is switched to the horizontal upright posture again. Thereafter, the transport container 4 is held in a horizontal upright posture by the guide rails 27 of the container posture control means 29 being supported by the guide rollers 19a to 20b, and moves horizontally, and subsequently, the groove-shaped guide rails 25B and 26B. Inside the guide rollers 19a-20b
Is moved, the transport container 4 raises and turns the tip turn portion 1c while maintaining the horizontal upright posture, and enters the original upper horizontal path portion 1a.

Therefore, if excavated earth and sand etc. are thrown from the transported object feeding section 5 into each of the transport containers 4 that horizontally move by connecting the upper horizontal route portion 1a of the lower horizontal route 1 in a row, the inside of each transport container 4 And the like are transported to the tip turn portion 3b of the upper horizontal path 3 by the transport container 4 which moves while maintaining the horizontal upright posture, and the transport container 4 is brought to the vertical posture in the subsequent object discharge part 6. It is switched and further changed to a horizontal upside-down posture, so that it is released by gravity.

Explaining in more detail the phenomenon of discharge of earth and sand, etc., when the transport container 4 moving from the tip turn portion 3b to the lower horizontal path portion 3c is switched to the vertical posture by the container posture control means 37, The earth and sand try to lower to the lower end (front end) side of the transport container 4 in the vertical posture due to gravity, but the transport container 4 does not continuously turn over to the horizontal upside-down posture, but keeps its vertical posture. Since it moves over a distance, the soil and the like inside is surely given an opportunity to slide by gravity toward the lower end (front end) side of the transport container 4 in the vertical posture. Moreover, the elastic sheet 38 moves toward the outside of the transport container 4 while being deformed so as to hang down integrally with the earth and sand along with the tendency of the earth and sand to slide, and at the same time, the elastic sheet 38 is separated from the protrusion 40 to cause the protrusion. Since the elastic sheet 38 that has been deformed in a wave shape along the line 40 is in a freely deformable state,
The elastic sheet 38 and the inner sand that tend to slide downward
A large relative slip between the elastic sheet 3 and
The sliding resistance of the earth and sand to 8 is greatly reduced, and the earth and sand inside will slide down vigorously with inertia.

Most of the earth and sand inside the carrier container 4 will slide off from the carrier container 4 while the carrier container 4 is moving in a vertical posture, but some of it will be elastically deformed and left in the container. The sheet remains in the state of being wound around the sheet 38 or attached to the elastic sheet 38. However, next, the transport container 4 rotates to the horizontal upside down posture, and at this time, the elastic sheet 38 is deformed so as to hang completely out of the container by gravity as shown in FIG. 3B. Due to the inertia applied to the adhered earth and sand and the relative slippage due to the deformation of the elastic sheet 38, almost all of the earth and sand adhering and remaining on the elastic sheet 38 is easily separated from the elastic sheet 38 and falls. Become.

The empty transport container 4 in the upside down posture descends in a state where the descending path portion 2b of the vertical path 2 is returned to the horizontal upright posture, and the lower horizontal path portion 1 of the lower horizontal path 1 is lowered.
Although it enters the inside of b, at this time, each of the transport containers 4 temporarily changes to the tilted posture. Therefore, if necessary, the cleaning means 3 is moved toward each of the transport containers 4 that changes from the horizontal upright posture to the tilted posture.
By injecting cleaning water from the nozzle 33 of No. 4, it is possible to wash off the earth and sand adhering and remaining on the inner surface of the transport container 4 including the surface of the elastic sheet 38. The cleaning water does not collect in the transport container 4 because it moves while maintaining a tilted posture for a while.

The lower horizontal path portion 1 of the lower horizontal path 1
In b or the descending path portion 2b of the vertical path 2, the transport container 4 is in an upside down posture parallel to the moving direction (moving posture of the transport container 4 in the latter half of the lower horizontal path portion 3c in the upper horizontal path 3). It may be configured to move. In this case, if the cleaning means 34 is provided side by side, for example, the cleaning water may be sprayed toward the inner surface of the transport container 4 that descends the descending path portion 2b of the vertical path 2. Further, depending on the property of the material to be transported such as earth and sand, a conventional configuration in which the transport container 4 is inverted to the horizontal upside down posture at the tip turn portion 3b of the upper horizontal path 3 can also be adopted.

When the protrusion 40 for deforming the elastic sheet 38 into an uneven shape is adopted, when the input sand contains a large lump of stone, the elastic sheet portion deformed by the protrusion 40 into a protrusion shape. Since the stone blocks and the like are intensively hit, the elastic sheet 38 is easily damaged. Therefore, it is desirable that the protrusion 40 itself be made of an elastic material, or that the protrusion 40 having at least its top portion covered with an elastic material be used.

[0031]

According to the continuous vertical carrying device of the present invention which can be implemented and used as described above, when the elastic sheet which overlaps the inner bottom surface of the carrying container is in a horizontal upside down posture. It is stretched so that it hangs away from the inner bottom surface of the container due to gravity, so the transfer container is reversed at the container reversal path part (transported material discharge part) from the tip turn part of the upper horizontal path to the lower horizontal path part. At this time, the elastic sheet is deformed so as to hang down apart from the inner bottom surface of the container due to gravity together with the earth and sand which are about to fall.

That is, even if the transport container is turned upside down 180 degrees at the end turn portion of the upper horizontal path, the adhesion between the elastic sheet and the container inner bottom surface is not affected by the elastic sheet and the covered sheet. It is small compared to the adhesiveness with the transported material such as earth and sand.Therefore, the earth and sand that is in direct contact with the inner bottom surface of the transport container that has been turned upside down will adhere to the inner bottom surface of the container. Even if gravity makes it difficult to separate and drop by gravity alone, the elastic sheet easily separates from the inner bottom surface of the container, which promotes the falling motion of earth and sand in the container.

Moreover, since the elastic sheet hanging from the inner bottom surface of the container is largely deformed from the shape when it overlaps with the inner bottom surface of the container, the elastic sheet and the earth and sand contacting the elastic sheet are deformed due to the sagging deformation of the elastic sheet. Relative slippage occurs between the two, and the two can be easily separated.
Furthermore, the inertial force acting on the earth and sand or the like that is going to fall out of the container with the hanging of the elastic sheet effectively acts as a separating force of the earth and sand and the like from the elastic sheet when the hanging and deformation of the elastic sheet is completed. As
Even when handling transported objects that tend to adhere and remain on the inner surface of the transport container, such as clay-like mud and sand with high moisture content and high viscosity, from the transport container that is reversed at the transported object discharge part It can be surely released.

Therefore, in the path portion where the empty transport container moves in the horizontal upside down posture or the vertical posture, the failure caused by the continuous sliding of the residue in the container due to gravity or vibration is eliminated or greatly reduced. Moreover, it is not necessary to frequently perform maintenance work including cleaning of the inside of the apparatus in order to avoid such a situation.

Of course, as described in detail in the embodiments, projections for making unevenness on the elastic sheet are provided on the inner bottom surface of the container on which the elastic sheet overlaps, or both ends of the elastic sheet are opened in the transport container. By swingably pivoting on both ends of the part via hinges to increase the amount of sagging deformation of the elastic sheet and to facilitate the sagging deformation, the elastic sheet releases soil and sand. The promoting effect can be made more remarkable. Further, after holding the carrier container in a vertical position rotated by about 90 degrees from the horizontal upright position on the path portion serving as the discharged part of the transferred object for a certain distance from the tip turn part of the upper horizontal path, the transfer of the vertical position is performed. If a container attitude control unit that changes the container to the horizontal upside down posture is provided, relative sliding between the elastic sheet and the earth and sand will be more reliable than when the transport container is suddenly inverted to the horizontal upside down posture at the tip turn part. When the elastic sheet is generated, the effect of accelerating the release of earth and sand by the elastic sheet can be further increased.

Claims (4)

[Claims] 1. A boat shape in which a path from an upper horizontal path portion of a lower horizontal path in a Z-shaped circulation path to an upper horizontal path portion of an upper horizontal path through a rising path portion of a vertical path is connected at appropriate intervals. A continuous vertical transfer device in which a transfer container is a transfer path part that moves in a horizontal upright position, and a container reversal path part from the tip turn part of the upper horizontal path to the lower horizontal path part is the object discharge part. A continuous vertical transport device in which an elastic sheet that overlaps with the inner bottom surface of the transport container is stretched so as to hang down apart from the inner bottom surface of the container by gravity when the transport container is in a horizontal upside down posture. 2. A protrusion for making unevenness on the elastic sheet is formed on a bottom surface inside the container on which the elastic sheet overlaps.
The continuous vertical transport device described in. 3. The continuous vertical transfer device according to claim 1, wherein both side ends of the elastic sheet are pivotally attached to both side ends of the opening of the transfer container via hinges. 4. The carrier container is held in a vertical position, which is rotated by approximately 90 degrees from a horizontal upright position, in a path portion which serves as the transported object discharging part, over a certain distance from a tip turn part of an upper horizontal path. The continuous vertical transport device according to any one of claims 1 to 3, further comprising container posture control means for changing a vertical transport container to a horizontal upside-down posture.
