[0008] The transport device for a passenger conveyor according to the present invention comprises:
As described above, a hand-wound winch is used as the lifting device, so that it is small and lightweight, and can be used to lift a heavy object such as a wheelchair step with a small operating force. Since the rope guide is attached so that the position can be adjusted in the direction opposite to the handrail, even if turbulent winding occurs in the manual winding winch and the length of the left and right lifting ropes differs, the sorting rope guide slides in the shorter direction. Since the correction is made by moving, the heavy object can be stably held without tilting.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a front view showing a passenger conveyor transport device according to an embodiment of the present invention, which is used for transporting a wheelchair step of an escalator. On the escalator, handrails 4 are arranged on both sides of a central step attachment portion so as to be able to travel with respect to the support member 26. Wheelchair steps 2 on this pair of handrails 4
Is constructed. As shown in the side view of FIG. 2 and the plan view of FIG. 3, two wheels 6 rolling on the handrail 4
Each of them is arranged so as to engage with the handrail 4 to prevent detachment. A beam 7 rotatably supporting each of the wheels 6 is disposed so as to straddle between the handrails 4, and a support member 14 is provided at the left and right positions above the beam 7.
A pair of rope guides 9 rotatably supported by the handrails are arranged, and a hand-wound winch 8 having a pair of distribution rope guides 11 slides in the direction opposite to the handrail 4 at the upper center of the beam 7. Supported as possible. This manually wound winch 8 includes a winding drum section 21, a reduction gear section 22 having a built-in brake, a crankshaft 23, and a crankshaft 23.
, And a manual winding operation section 24b attached to the other end of the rotary operation handle 24.

The hoisting ropes 10a, 10
When the operation handle 24 is rotated clockwise, for example, the lifting ropes 10a, 10b are simultaneously wound, and when the operation handle 24 is rotated in the opposite direction, the lifting ropes 10a, 10b are simultaneously rewound. It is configured. The lifting ropes 10a and 10b from the winding drum 21 are separated to the left and right by a pair of distribution rope guides 11 which are rotatably supported by a support member 16 provided at the center of the beam body 7. Each end is suspended below the beam body 7 via the rope guide 9. Now, in the illustrated state, the lifting ropes 10a, 10
The lifting brackets 15 of the wheelchair steps 2 are connected to the ends of b through shackles 18, respectively. However, as a passenger conveyor transportation device, the wheelchair steps 2 are separated from the shackle 18. You. Support member 16
Are supported by a sliding means 17 having a rail 17a disposed at the upper center of the beam 7 and extending in the longitudinal direction of the beam 7, and a block 17b slidably guided along the rail 17a. Specifically, the support member 16 is supported on the block 17b of the sliding means 17, and the distribution rope guide 11 is configured to be slidable in the left-right direction within the length of the rail 17a.

Next, the operation of carrying the wheelchair steps 2 from the entrance of the escalator using the passenger conveyor device having such a configuration will be described. First, the beam 7 is arranged between the left and right handrails 4 of the escalator, and the wheels 6 at both ends are placed on the handrail 4. Before and after this work, the wheelchair steps 2 are carried to the entrance by a bogie (not shown). Next, a demarcation portion (not shown) on both sides of the wheelchair step 2 is removed so that the wheelchair step 2 can be lifted, and the suspension bracket 15 is fixed using the screw holes. Then, the shackle 18 is used to lift the rope 1
The ends of Oa and 10b are connected to the suspension bracket 15, respectively.

When the operation handle 24 of the manually-wound winch 8 is rotated in a predetermined direction after such a preparation operation, the lifting ropes 10a and 10b are wound around the winding drum 21 so that the wheelchair step 2 is lifted. . here,
When the two lifting ropes 10a and 10b are wound around the winding drum section 21, the lifting ropes 10a and 10b
Alternatively, there is a danger that the lengths of the respective steps become uneven due to, for example, overlapping, and the wheelchair steps 2 are inclined. However, in the above-described passenger conveyor conveying device, the distribution rope guide 11 is slidably provided by the sliding means 17, and when a difference in the length of the lifting ropes 10a and 10b occurs, the distribution rope guide is used. Since the correction can be made by the sliding of the wheel 11, the wheelchair step 2 can be constantly lifted almost horizontally and safely. Thereafter, the wheel 6 is moved on the handrail 4 while rolling, and when the wheel 6 reaches a predetermined position, the wheelchair step 2 can be suspended by reversing the operation handle 24 in a procedure reverse to the procedure described above. .

As described above, since the manually wound winch 8 is supported on the beam 7 disposed between the handrails 4 while supporting the wheels 6 rolling on the handrail 4, the manually wound winch 8 has the reduction gear portion 22. As a result, it is possible to achieve a small and lightweight and excellent workability as compared with the conventional configuration. The lifting ropes 10a and 10b of the manually-wound winch 8 are slidably attached to the center of the beam 7 in the direction opposite to the handrail 4 so as to be position-adjustable. The rope guide roller 9 attached to the handrail 4 side of the rope guide 11, and a heavy object such as the wheelchair step 2 is connected to the end of the rope guide roller 9. By adjusting the position, the load can be easily transported while maintaining the balance.

In the above-described embodiment, the description has been given of the transporting device for the passenger conveyor for transporting the steps 2 for wheelchairs. Also at the time of remodeling, it can be used for carrying heavy objects such as the wheelchair steps 2.
