Description

Unexpected protection device that removes of car

Technical Field

The utility model relates to the technical field of elevator cabs, in particular to a car accidental movement protection device.

Background

The car is a box-shaped space used by the elevator to carry and transport people and supplies. The car is generally composed of main components such as a car bottom, a car wall, a car roof, a car door, and the like. Is the body part of an elevator used to carry passengers or cargo and other loads. In recent years, safety accidents caused by accidental movement of an elevator car frequently occur, and hidden danger of accidental movement of the elevator car is not only difficult to avoid, but also cannot be completely eliminated. The causes of unexpected movement accidents of the elevator car come from a plurality of possibilities, and meanwhile, the plurality of possibilities have the characteristic of difficult finding and cannot be eradicated through general investigation. In order to avoid casualties caused by accidental falling of the elevator, protection measures are required to be arranged for the elevator car.

Chinese patent No. CN214569955U discloses an unexpected removal safety arrangement of elevator car, including elevator car and elevator shaft, and elevator car sets up in the inside of elevator shaft, unexpected removal safety arrangement of elevator car still includes: two separators symmetrically installed inside the elevator car; the two anti-falling mechanisms are symmetrically arranged on the elevator car and are used for preventing the elevator car from freely falling down when out of control; and the reset structure is arranged on the elevator car and the anti-falling structure and is used for resetting the anti-falling mechanism to the original position after working so as to prevent the elevator car from falling next time. According to the elevator car anti-falling mechanism, when the elevator car is free to fall, the elevator car can be timely and stably limited in the elevator shaft, and damage to personnel caused by long-distance falling of the elevator car is avoided.

Although the device beneficial effect is more, still there is the disadvantage to need improving, in only embedding the spacing recess of seting up on the elevator shaft through two anti-falling support columns when the car accidentally moves, it is not good to support the fixed effect that the elevator car supported, because the car bottom is the quadrangle, when the personnel position distributes in single position in the car, the balance of the other both sides position of car can not be guaranteed to the support column that two symmetries set up, very easily take place the skew phenomenon when the car removes, cause personnel injury in the car, in view of this, we propose a car accidental removal protection device.
