Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION This invention relates to passenger conveyors, and in particular to
The present invention relates to a tread plate attachment / detachment device for a passenger conveyor, which is suitable for a tread plate attachment / detachment operation in an automatic line device.

[0002]

2. Description of the Related Art Generally, a passenger conveyor has about 20 steps.
It weighed more than kg and was very heavy, and it was necessary to lift it vertically to remove it from the chain.

[0003]

In the above conventional structure,
One worker rides on the tread that is not detached from the chain,
The heavy pallet where the worker needs to be detached must be lifted vertically in a bent position. Therefore, there is a problem in that the worker may hurt his back or may accidentally drop the tread during transportation of the tread. Also, since the tread is heavy and the posture of lifting the tread is not good, it is difficult to lift in the vertical direction, and the operator's hand is hurt when lifting the tread. There was a problem that I could not do it.

In view of the above problems, it is an object of the present invention to safely and easily remove and attach the treads efficiently without damaging the back of the operator or dropping the treads. (EN) Provided is a demounting device for a footboard of a passenger conveyor which can be carried out.

[0005]

The above object comprises a support movably provided on a handrail, a jack mounted on the support, and a wire rope depending from the jack. This is achieved by providing a plurality of hooks for engaging the side surface concave portion of the tread plate and pulling up the tread plate in the vertical direction.

[0006]

First, in order to attach and detach the tread, the jack is set above the tread by placing the support on the handrail. After that, the handle of the jack is turned to loosen the wire rope, and the plurality of hooks provided on the wire rope are locked in the side surface recesses of the tread. In this state, if you turn the handle of the jack and pull up the wire rope, the tread will rise vertically and easily disengage from the chain.

Next, if the tread comes off the chain,
The tread is rotated about 90 degrees below the skirt base. By moving the support along the handrail while maintaining this state, the tread can be moved to the end of the handrail without colliding with the balustrade glass or the like provided below the handrail. If you move the tread to the end of the handrail,
Turn the handle of the jack to loosen the wire rope,
After placing the tread on the floor, the hook may be removed from the side surface recess of the tread.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described with reference to FIGS.

In the figure, 1 is a passenger conveyor tread, 1a is a rear wheel roller provided on both sides of the tread 1, 2 is a handrail provided on both upper sides of the tread 1, and 3 is a lower side of the handrail 3. The tempered glass provided on the 4 is a skirt base for fixing a skirt guard (not shown),
5 is a support, 6 and 6a are provided on both sides of the support 5, and are rollers 7, 7 for moving on the handrail 2.
7a is a roller which is at both ends of the support body 5 so as not to be separated from the handrail 2, 8 is a jack fixed to the center of the support body 5 for lifting the tread 1, 8a is a handle for operating the jack, and 8b is a Hook for hanging the tread 1, 9 is a wire rope, 10a, 10b, 10c, 10
Reference numeral d denotes a hook which is hooked on the recesses on both sides of the tread 1.

Next, the operation of removing the tread plate 1 and moving the tread plate 1 is carried out by removing the inner deck board, the skirt guard, and the tread plate mounting bolt (not shown), and then removing the handrail from the upper part of the tread plate 1 to be removed. 2 Place the rollers 6 and 6a on both sides and lower the hook 8b toward the tread 1. Next, the hooks 10a, 10b, 10c and 10d are attached to the tread 1
Hook the wire ropes 9 and 9a on the hooks 8b and turn the handle 8a of the jack 8 to move the tread 1
Pull up. At this time, if the tread 1 is pulled up too much, the rear wheel roller 1a hits the skirt base 4, so that it is rotated about 90 degrees below the skirt base 4 and above the tread 1 before being pulled up. Next, in this state, pull up the tread plate 1 to a position where it is easy to move, move the tread plate 1 to the end of the handrail, and then turn the handle 8a of the jack 8 to put the tread plate 1 on the floor surface. Hook 1
0a, 10b, 10c and 10d are removed from the side surface recesses of the tread 1. Next, after cleaning the inside of the opening formed after the detached tread 1, the tread 1 is attached by performing the work in the reverse procedure of the removal work.

[0011]

According to the present invention, the footboard of the passenger conveyor can be safely and easily and efficiently attached / detached to / from the passenger conveyor without injuring the back of the operator or dropping the footboard. The desorption device was obtained.
