Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a lifting device for heavy equipment in a machine room on a passenger conveyor.

[Conventional technology]

In a typical passenger conveyor, heavy equipment such as a drive machine and an electric motor with a reduction mechanism are housed in a machine room below the floorboard of the passenger entrance.

Conventionally, when a drive machine or an electric motor with a speed reduction mechanism breaks down or needs to be replaced, it is difficult to simply lift it up and carry it in and out, since these are quite heavy objects. For this reason, the drive machine and electric motor with speed reduction mechanism had to be disassembled in the machine room and transported in and out. Furthermore, a portable bridge type crane such as that described in Japanese Utility Model Application No. 51-93562 can be used for loading and unloading a drive machine or an electric motor with a speed reduction mechanism.

This portable bridge crane consists of a pair of A-type support legs that can be disassembled, casters attached to the lower ends of the A-type support legs, and both upper ends of the A-type support legs arranged at intervals. The system includes a hoist suspension beam coupled therebetween, a trolley movably supported on the hoist suspension beam, and a hoist attached to the trolley.

[Problem that the invention seeks to solve]

However, when the floorboard of the machinery room is removed in order to lift the drive unit and electric motor with reduction mechanism, long, thin holes are left on the left and right, and when the portable bridge crane is placed in place, at least more holes than necessary remain on both the left and right sides. Therefore, the hoist must be operated and the condition and position of the heavy equipment being hoisted must be visually checked from a distance, which results in poor operability and cannot ensure safety.

An object of the present invention is to provide good operability and ensure safety when carrying heavy equipment into and out of a passenger conveyor machine room without disassembling the equipment to be carried in and out.

[Means for solving problems]

The above purpose is to reduce the weight inside the machine room of the passenger conveyor, which is installed above the machine room installed at the bottom of the floorboard of the passenger conveyor's entrance and exit, and is used when carrying heavy equipment such as electric motors into and out of the machine room. The equipment hanging device has an opening in the center that is narrower than the plane shape of the machine room, and when lifting heavy equipment in the machine room, there is a hole in the upper part of the machine room after removing the floor plate that leads to the machine room. A plate-shaped base installed to cover the surrounding area, a pair of pillars erected on this base, an upper beam bridging the tops of these pillars, and a hanging hook attached to this upper beam. This is achieved by having a configuration that includes the following.

[Effect]

With the above configuration, by leaving the base in place for carrying heavy equipment in and out of the machine room, the area around the hole leading to the machine room is covered, thereby eliminating the need for holes leading to the machine room such as on the left and right sides of the pillars. areas are blocked. Therefore, it is possible to visually check the lifting operation and the status of the heavy equipment in the machine room to be lifted, for example, whether there is a risk of contact with other equipment, from a position close to the lifting hook, improving operability and ensuring safety. Heavy equipment in the machine room can be moved in and out. Furthermore, since a hanging device is used, there is no need to disassemble heavy equipment in the machine room.

〔Example〕

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a passenger conveyor hoisting device according to the present invention will be described below with reference to the drawings.

FIG. 1 is a plan view of a passenger conveyor according to the present invention;
FIG. 2 is a partially cutaway side view thereof.

A machine room 20 is located under a floor plate 13 at the entrance to the passenger conveyor 10, which is composed of a moving handrail 11 and a step 12. Large heavy equipment such as a drive machine 21 and an electric motor 22 are installed inside this. A gate-shaped suspension 1 is installed on a floor beam 14 that supports this floor plate 13. This gate-shaped suspension 1 is installed on a floor beam 14, and a first pillar 4 is placed on a flat base 3 that has an opening in the center that is narrower than the plane shape of the machine room.
A pair of pillars each consisting of a pillar 4b and a second pillar 4b are provided, and an upper beam 5 having a hanging hook in the center is bridged between the upper parts of the pillars.

The hanging hook used here is composed of a chain block or the like which itself has a telescoping function. Furthermore, the pillar material of the gate-shaped hanging rod consists of a first pillar 4a and a second pillar 4b, and the height of the pillar can be changed arbitrarily by providing a through hole in both and fixing with bolts or the like. be able to. Further, the upper beam 5, the pillar material, and the base 3 can be disassembled, so that they can be carried in and assembled separately, so that the gate-shaped suspension 1 can be easily installed. Furthermore, by placing the base 3 on the machine room 20 with the floorboard removed, the area around the hole in the machine room 20 is covered by the base 3, so that when the worker approaches the hanging hook 2,
It is possible to visually check the operation of the hanging hook 2, the position of the suspended heavy equipment in the machine room 20, whether there is a risk of contact with other equipment, etc., and the operability is improved. Furthermore, since the base 3 is a plate-shaped member large enough to cover the machine room 20, the lifting gear 1 is stable when lifting heavy equipment.

〔Effect of the invention〕

As explained above, according to the present invention, when carrying heavy equipment in and out of the passenger conveyor machine room, the machine in the passenger conveyor can be operated easily and ensure safety without disassembling the equipment to be carried in and out. We can provide indoor heavy equipment lifting equipment.
