[0009]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of a passage facility of the present invention will be described with reference to FIGS.
In the present embodiment, for example, an escalator 1 is provided as a passenger conveyor. The escalator 1 is a thin escalator in which the height of a frame forming a main body is formed smaller than that of a normal escalator, as described later.
[0010]
The escalator 1 includes a frame 2 forming a main body as shown in FIGS. 3 and 4, a balustrade 3 erected on the frame 2 as shown in FIG. 1 and the like, a step 4 for carrying passengers, and this step 4 And a handrail 5 which moves in synchronization with the handrail 5. The escalator 1 has an overall shape including an upper flat portion 12, an inclined portion 13, and a lower flat portion 14.
[0011]
The escalator 1 is disposed, for example, on a building at a railway station, for example, on a platform 16. As shown in FIG. 3, the frame 2 that constitutes the lower flat portion 14 of the escalator 1 is housed in a building having a walking path on the upper surface, for example, an excavation section 19 formed in a platform 16. As shown in FIG. 3, a pit structure 20 made of concrete or the like is formed in the excavation portion 19.
[0012]
The platform 16 is arranged such that the upper surface forming the walking passage is higher than the track 17 installed on a predetermined ground 18 adjacent to the platform 16.
[0013]
As shown in FIG. 1 and the like, an exterior wall 6 is provided on one side of the escalator 1, and a stairway 7 is formed adjacent to the exterior wall 6 to form a walking path for passengers. In the middle of the stairs 7, for example, a landing 9 is provided. In the vicinity of the exterior wall 6, a handrail 11 for stairs for a user of the stairs 7 is provided.
[0014]
For example, the upper surface of the platform 16 and the floor near the lowermost part of the stairs 7, that is, the lower floor 10, are formed flush with each other. The floor near the uppermost part of the staircase 7 is an upper floor 8 that forms a walking passage connected to, for example, a ticket gate. The lower entrance 1 a of the escalator 1 is provided on the lower floor 10, that is, on the upper surface of the platform 16.
[0015]
In particular, in the present embodiment, as shown in FIG. 3, excavation on the ground 18 where the railroad track 17 is installed is below the excavation part 19 where the frame 2 part forming the lower flat part 14 of the escalator 1 is stored. In addition to the reinforcing portion 21 for suppressing the adverse effect of the excavation of the portion 19, the excavation depth of the excavation portion 19 is H1, the height of the reinforcement portion 21 is H2, and the height from the surface 18a of the ground 18 to the upper surface of the platform 16 is set. When the height dimension is H3,
H3 = H1 + H2
The dimensional relationship is set.
[0016]
According to the investigation and test results of the present inventors, the height dimension H3 to the upper surface of the platform 16 is generally 1000 to 1300 (mm), and the end of the platform 16 shown in FIG. In the case where the shortest distance H4 from the part 16a to the escalator 1 is within 2000 mm and there is a region on the upper surface of the platform 16 located between the end 16a of the platform 16 and the escalator 1 on which the passenger can pass. For example, when the excavation depth dimension H1 is set to 500 to 800 (mm) and the height dimension H2 of the reinforcing portion 21 is set to 200 mm or more, the adverse effect on the ground 18 of the track 17 when excavating the excavation portion 19 is reduced. It was confirmed that it could be suppressed.
[0017]
As shown in FIG. 4, the escalator 1 includes a driving sprocket having a smaller diameter than that of a general escalator, for example, having 18 teeth, on a reversing portion 22 of the step 4 provided on the upper flat portion 12 of the frame 2. 23 are arranged. The front wheel 24 of the step 4 is guided by a front wheel guide rail 25, and the rear wheel 26 of the step 4 is guided by a rear wheel guide rail 27. The track of the front wheel guide rail 25 is located outside the rear wheel guide rail 27 in the width direction of the frame 2, that is, in the direction orthogonal to the plane of FIG. A chain 28 having a chain pitch of, for example, 6 for connecting the front wheel shafts of the steps 4 is provided, and the chain 28 and each front wheel shaft are connected by a specific link 29 having a triangular shape. The specific link 29 is provided with an elongated hole 30 that enables displacement of the front wheel axle. The elongated hole 30 extends in a direction substantially orthogonal to the direction in which the chain 28 extends.
[0018]
The operation of this component will be described. When the step 4 moving on the outward path approaches the reversing portion 22, but is still located on the near side, the step surface of the step 4 is held horizontally upward with the front wheel axle connected to the specific link. It is located at the lower end of the elongated hole 30 of the 29. From this state, the step 4 starts to be inverted, and the front wheel axis moves along the extending direction of the elongated hole 30 of the specific link 29 until the front wheel 24 reaches almost the center height position of the drive sprocket 23. When the front wheel 24 reaches almost the intermediate height of the drive sprocket 23, the front wheel shaft is located at the upper end of the elongated hole 30, that is, at the rightmost end in FIG. Further, when the step 4 is reversed and the tread surface of the step 4 is held downward and horizontally to return to the return path, the front axle is located at the lower end of the long hole 30 of the specific link 29 again.
[0019]
By performing such an operation, the track 31 of the chain 28 and the track 32 drawn by the front wheel axle of the step 4 are substantially on the outward path to the reversing section 22 and the return path after passing through the reversing section 22. Although coincident, the track 32 of the front wheel shaft of the step 4 is located outside the track 31 of the chain 28 in the reversing section 22. That is, the trajectory approximates the trajectory of a chain wound around a drive sprocket provided in a normal non-thin escalator. Thus, the step 4 to be reversed and the step 4 adjacent to the step 4 do not interfere with each other, and the reversing operation of these steps 4 can be performed smoothly.
[0020]
As described above, since the driving sprocket 23 has a smaller diameter than that of a normal escalator, in this embodiment, the height H of the frame 2 shown in FIG. For example, it can be reduced by about 20 to 30% compared to the dimensions. Thus, the escalator 1 is configured as a thin escalator whose overall height is lower than that of a normal escalator. Therefore, in the above-described embodiment in which the reinforcing portion 21 shown in FIG. 3 can be easily set to a size of, for example, 200 mm or more, the lower flat portion of the escalator 1 is used as described above. Since the reinforcing portion 21 is provided below the excavation portion 19 in which the frame 2 portion of the portion 14 is stored, when the above-described excavation portion 19 is provided on the platform 16, the ground 18 of the track 17 adjacent to the platform 16 is excavated. Adverse effects due to the excavation work are suppressed, and the ground 18 of the track 17 can be maintained in a stable state without loosening or collapse.
[0021]
Therefore, it is not necessary to repair the ground 18 of the railroad track 17 after the excavation work of the excavation section 19, and the escalator 1 can be installed without concern that a special time and cost for such repair work are required. In addition, the escalator 1 can be installed without disturbing the railway user in the repair work of the ground 18 of the track 17.
[0023]
Further, in the above embodiment, the escalator 1 is described as an example of the passenger conveyor, but the present invention is not limited to this, and may be applied to a moving sidewalk or the like.
[0024]
Further, in the above embodiment, the passage equipment in which the escalator 1 is installed on the platform 16 of the railway station has been described. However, the present invention is not limited to this, and is adjacent to a predetermined ground and located at a position higher than the predetermined ground. The present invention can be applied to any passage equipment provided with a building having a walking passage formed on an upper surface thereof and a passenger conveyor at least partially housed in an excavated portion formed by excavating a predetermined portion of the building. is there.
[0025]
【The invention's effect】
As described above, according to the present invention, the passenger conveyor can be installed without adversely affecting the predetermined ground adjacent to the building on which the passenger conveyor is installed, and therefore, at least one of the passenger conveyors can be installed. It is no longer necessary to carry out the repair work on the predetermined ground, which has been a concern in the past after the excavation work of the excavation part in which the part is stored, and the passenger concerned can be carried out without requiring special time and cost for such repair work. A conveyor can be installed.
