[0005]

When performing a maintenance inspection on such a moving sidewalk, it is necessary to assemble a work and a stirrer at the maintenance and inspection place, attach a chain block and the like to the work and the stairs, and perform the work of hanging down the equipment. In particular, when performing maintenance and inspection of many places on a long moving walkway, the work and the stairs must be assembled and disassembled many times.

The present invention has been devised to solve the above-mentioned problems. It is assembled at the time of maintenance and inspection, maintenance and inspection is performed while moving, and after maintenance and inspection, it is disassembled and stored near a moving sidewalk. It is an object of the present invention to provide a crane for maintenance and inspection of a moving sidewalk which can be placed and placed.

[0007]

According to the present invention, a large number of pallets are arranged on a rail formed by combining two straight portions and two semicircular arc portions in an endless manner. This is a crane for maintenance and inspection of a moving sidewalk, which is placed side by side so as to overlap partly, and puts personnel on a pallet, and which is laid along the straight part on both sides of each straight part. A pair of trolleys to move, a pair of inverted V-shaped legs erected on the trolley, and a crane girder connected so as to straddle any one linear part of the sidewalk moving between the tops of the legs. A trolley block that moves on a crane girder to lift and lower equipment, and a reinforcing member provided inside one leg and connected between a bogie and a crane girder to form a truss When performing sidewalk maintenance and inspection, And, after the maintenance completion of the maintenance and inspection for the crane of the moving walkway that was to be stored by decomposition is provided.

According to a preferred embodiment, each of the bogies, each of the legs, the crane girder and the reinforcing member are assembled with each other so as to be disassembled with pins.

Next, the operation of the present invention will be described. When setting up a moving sidewalk, lay rails on both sides of each straight section of the moving sidewalk in advance. At the time of maintenance and inspection of the moving sidewalk, a bogie and legs are taken out of a storage room (not shown) provided near the moving sidewalk, and a maintenance and inspection crane is assembled on the rail. After assembling, perform maintenance and inspection work while moving on the rails. When the maintenance and inspection are completed, the robot moves on the rails, moves to the vicinity of the storage room, disassembles and stores. As described above, since the maintenance and inspection crane moves while hanging the equipment along the linear portion of the moving walkway, the maintenance and inspection work is easy and safe. Further, since each bogie, each leg, the crane girder, and the reinforcing member are assembled by being disassembled with pins, respectively, assembly and disassembly are easy.
