Abstract

PURPOSE:To perform safe work on a cage by suspending a plurality of chains in a reed screen state from a receiving beam set up in the uppermost part in a lift path where an elevator cage is lifted. CONSTITUTION:A plurality of aluminum chains 4 are fitted by a piping fixing metal fixture 5 to a lower flange of a receiving beam 2 and suspended in a reed screen state from the lower flange set up in the uppermost part in a lift path of an elevator. The chain '4 is set to a length in a degree such that jumping up in the uppermost story of a cage 1 and a surplus lift amount are measured further with no direct contact with the cage 1. As the cage 1 rises to approach an upper part of the lift path, a worker on the cage 1 approaches the receiving beam 2, and the reed screen-shaped chain 11 is naturally placed in a field of view of the worker to sense a position relation of the receiving beam 2. Or even in the case of the chain 4 not in the field of view at all, the body comes into contact with the chain 4 to become aware of it, and the receiving beam 2 can be avoided. In this way, work on the cage 1 can be safely performed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a safety work device for work on a car of an elevator.

[0002]

2. Description of the Related Art A conventional elevator car work will be described with reference to FIG.

Generally, the work on the car 1 is indispensable for the installation and inspection work of the elevator. However, the work on the car 1 is unstable at a high place, and the hoistway has protrusions. The work environment is in bad condition due to the above.

During the work on the car 1 during the installation and inspection of the elevator, as the car 1 rises in the hoistway, for example, the receiving beam 2 installed at the top of the hoistway is the worker 3 on the car 1. , The space with the receiving beam 2 is necessarily narrowed. At this point, the receiving beam 2 becomes dangerous to the worker 3, and may cause an accident due to contact or the like.

As described above, since many devices and facilities that may cause an accident are installed in the elevator hoistway, especially in the upper part, the influence on the operator 3 on the car 1 is great.

[0006]

As described above, at the uppermost part of the elevator hoistway, there is a normally safe installation, but it can be a hazardous material depending on the case. In addition, there is a great risk that an accident may occur during elevator installation and on-car work during inspection work.

In view of the above, it is an object of the present invention to provide a safe working apparatus capable of improving the safety of a worker when working on a car.

[0008]

In order to achieve the above object, the present invention mounts a plurality of aluminum chains in a comb shape on a receiving beam installed at the uppermost part of the elevator hoistway. The aluminum chain jumps up on the top floor of the car,
Also, in consideration of the amount of head to be lifted, hang a product of a length that does not directly contact the car.

[0009]

With the safety work device having the above-mentioned structure, the worker on the car who has risen to the vicinity of the uppermost part of the elevator hoistway is
A blind aluminum chain will be seen or come into contact with it to notice the receiving beam, which will give a warning for the accident.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An elevator car safety work apparatus according to the present invention will be described with reference to the embodiments shown in FIGS.

A plurality of aluminum chains 4 are attached to the lower brim of the receiving beam 2 installed at the uppermost part of the elevator hoistway by means of pipe fixing fittings 5, and are suspended in a comb shape. The length L of the aluminum chain 4 is set to a length that measures the amount of jump and surplus lift on the uppermost floor of the car 1 and is suppressed so as not to come into direct contact with the car 1.

As the car 1 rises and approaches the upper part of the hoistway, the operator on the car approaches the receiving beam 2, and the interdigital aluminum chain 4 naturally comes into the operator's field of view, so that the projection or receiving beam 2 You will detect the positional relationship. Alternatively, even if the aluminum chain 4 does not get into the eyes at all, the body comes into contact with the aluminum chain 4 and notices this, so that the receiving beam can be avoided.

The same effect can be obtained by applying a plastic chain, a net, a rope or the like instead of the above aluminum chain.

[0014]

According to the present invention, safe car work can be performed by avoiding contact and collision accidents of workers on the car during installation and inspection work of the elevator.
