Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an elevator car deformation prevention device, and more particularly to an elevator car deformation prevention device suitable for freight elevators.

As shown in Figure 1, the elevator car has a car floor 4,
A floor frame 8 that supports this via an elastic body 7, and this floor frame 8.
slings 5 arranged in parallel to support the
It is formed by assembling ceiling panels, doors, etc.

In addition, 3 is a car side sill, 9 is a car floor reinforcing material, and 2 is a landing side sill.

In such a configuration, when cargo 1 is to be brought in from the landing side, the car floor 4 is moved to the floor frame 8 at the moment the cargo 1 is moved to the car side, since the two sills 2 and 3 are not integrated. The strength of the elastic body 7 may be exceeded and the elastic body 7 may be moved to a large extent, resulting in damage to the elastic body 7.

As a countermeasure against this problem, in order to restrict movement that would damage the elastic body 7 of the car floor 4, a stopper 6 was protruded from the side surface of the reinforcing member 9, and this stopper 6 was opposed to the sling 5 with a gap δ.

However, in this configuration, the stopper 6 is attached to the reinforcing material 9 of the car floor from between the slings 5 arranged in parallel, so the workability and adjustment of the gap δ are extremely difficult to attach the stopper, and it is difficult to carry the cargo. Since the sling 5 directly receives the displacement of the car floor 4 due to the impact of time, the sling 5
is deformed, and the positional relationship between the guide roller or guide shoe attached to the sling 5 and the guide rail is disturbed.

SUMMARY OF THE INVENTION An object of the present invention is to provide an elevator car deformation prevention device that prevents deformation of a sling, which is a component of the car, and allows easy installation and adjustment of a stopper.

In order to achieve the above object, the present invention makes the length of the floor frame in the direction of the car doorway shorter than the reinforcing material for reinforcing the car floor, and also attaches the car floor to the lower surface of the reinforcing material on the side of the car doorway. Install a stopper to restrict movement in the direction of the entrance and exit,
This stopper is attached to the end of the floor frame on the side of the car entrance so as to face it with a gap therebetween, and the stopper is configured to be able to adjust the range of movement of the car floor.

Embodiments of the present invention will be described below with reference to FIG.

Incidentally, the same reference numerals as in FIG. 1 indicate the same members, so the explanation thereof will be omitted.

In this embodiment, a floor frame 8 having a shorter length than the reinforcing material 9 is placed on the lower side of the end facing the landing side of the reinforcing material 9 that reinforces the car floor 4.
A stopper 10 is provided that faces the landing side end of the vehicle with a gap δ.

This stopper 10 is attached to the bottom side of the end of the reinforcing material 9.
1 is attached on one side, the other side is opposed to the end of the floor frame 8, and a push bolt 12 is screwed onto the other side, with its head facing the end of the floor frame with a gap δ.

With this structure, the car floor 4 moves in the direction of the arrow Z due to the impact when carrying the cargo 1 into the car, but the amount of movement is regulated by the push bolts 12 hitting the ends of the floor frame. By setting the gap δ to an appropriate value, the elastic body 7 will not be damaged.

Incidentally, the gap δ can be easily adjusted by screwing the push bolt 12.

Furthermore, since the floor frame 8 receives the impact when the sling is carried, there is no impact that directly acts on the sling 5, and deformation of the sling 5 can be prevented.

Furthermore, the installation of the stopper 10 is as follows.
The entire adjustment can be carried out using the relatively wide space at the bottom of the hoistway where there are no surrounding car components, so the work is easy and safe.

As explained above, according to the present invention, there is provided an elevator car deformation prevention device that prevents the deformation of the sling, which is a component of the car, and allows the installation and adjustment of the stopper to be performed easily and safely.
