DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for carrying steps of a passenger conveyor which carries the steps of a passenger conveyor through a doorway, and is particularly suitable for carrying a heavy step such as a wheelchair step. The present invention relates to a method for carrying a step of a passenger conveyor.

[0002]

2. Description of the Related Art FIG. 7 is a side view showing the overall structure of a passenger conveyor for a wheelchair. The passenger conveyor 1 shown in FIG.
Are a plurality of steps 2 and two wheelchair steps 2a connected endlessly, and a handrail 3 rotatably provided on both sides of these steps 2, 2a and interlocking with the steps 2, 2a.
And support these steps 2, 2a and the moving handrail 3,
And a truss 4 extending along the moving direction of the steps 2, 2a. Steps 2, 2 are located below the upper entrance 5a.
An upper machine room 5b is provided for accommodating a drive device (not shown) for driving the handrail 3 and the moving handrail 3, and the upper machine room 5b is covered with a floor plate 5c. A lower machine room 6b is also provided below the lower entrance 6a, and the lower machine room 6b is also covered by a floor plate 6c.

In this passenger conveyor 1, an upper machine room 5b
The steps 2, 2a circulate, for example, as an ascending escalator by the activation of the drive device inside. At that time, step 2,
2a is an upward state, from the lower machine room 6b to the upper machine room 5
b, the upper machine room 5b is turned upside down, and in the downward direction, the return route from the upper machine room 5b to the lower machine room 6b is lowered, and the upper machine room 6b is turned upside down again. To return to the upward state.

[0004] The two wheelchair steps 2a are arranged adjacent to each other, and each step 2a is provided with a vertical movement device for vertically moving the upper surface, that is, the tread surface as required. The treads of the two steps 2a are raised to the same height as the treads of the normal steps 2 located above by the operation of the up-down movement device. Since a relatively wide horizontal surface is formed by the tread surface 2a, a wheelchair can be mounted as shown in FIG. Thereafter, the vertical movement device is operated again to lower the tread surfaces of the two wheelchair steps 2a to predetermined height positions, respectively, so that it can be used as a normal passenger conveyor.

[0005]

In the above-described passenger conveyor 1 for wheelchairs, the weight of the ordinary steps 2 is about 2
The weight of the wheelchair steps 2a is about 1 in contrast to 5 kg.
Since the weight is 50 kg, when installing the wheelchair step 2a, the operator lifts the step 2a with four or five persons and transports the step 2a from the entrance 5a to a predetermined installation position. There was a problem that required a person.
In addition, there is a concern that when transporting the vehicle from the entrance 5a between the handrails 3, the safety is reduced due to the poor scaffolding and heavy work in a limited space.

The present invention has been made in view of such a situation in the prior art, and an object of the present invention is to provide a passenger who can smoothly and safely carry the steps of a passenger conveyor from an entrance / exit to a predetermined installation position. An object of the present invention is to provide a method for carrying a step of a conveyor.

[0007]

In order to achieve the above object, the present invention provides a truck on which a step of a passenger conveyor can be placed, an arm provided on the truck and capable of moving up and down and extending and contracting. A step of loading a passenger conveyor for loading the steps to a predetermined installation position via a doorway by using a heavy load carrying device provided with a heavy load suspension hook provided on a free end side of the arm; An installation step of installing the heavy goods transporting device so that the steps can be placed on the cart, a hook attaching step of attaching the hooks to the steps installed on the cart, and attaching the hooks to the steps. A lifting step of lifting the arm through the arm, a moving step of moving the step forward from the bogie by extending the arm, and a descending step of lowering the step to the predetermined installation position. Are you.

According to the present invention, the steps can be lifted by the arms of the crane device and can be carried into the predetermined installation position from the entrance / exit, so that the steps are not required as compared with the conventional case where the steps are carried in manually. Can be carried out smoothly and safely.
