Description

Elevator car locking device Technical Field The utility model relates to the technical field of elevator car locking, in particular to an elevator car locking device. Background With the rapid development of elevator technology, the building height of skyscraper is higher and higher, and as the application range of the elevator is wider and wider, the elevator plays an indispensable role in our daily life. An elevator refers to a permanent transport device that serves several specific floors within a building with its car running on at least two trains of rigid rails perpendicular to the horizontal or inclined at an angle of less than 15 ° to the plumb line. The vertical lift elevator has a car running between at least two vertical or inclined rigid guide rails at an angle of less than 15 deg. and a locking device is required to lock the elevator when it encounters a dangerous rapid drop. In the prior art, an elevator car locking device as disclosed in publication number CN220811532U comprises a mounting plate, a first motor is mounted on one side of the top end of the mounting plate through a mounting seat, and a winding wheel is fixedly arranged on the top end of the mounting plate. It is through removing the helping hand board to one side, because of the fixture block is two-sided trapezoidal setting, can make the fixture block follow the fixed block surface and remove, until the fixture block leaves the draw-in groove, after canceling the fixed effect between fixed block and the connecting block, can easily take off the resistance board, be convenient for maintain the change to the resistance board, make the resistance effect of its resistance board keep stable to keep equipment overall stability, easy operation is convenient for the staff to change the resistance board by oneself fast simultaneously, has improved maintenance efficiency. The existing locking device can enable the clamping block to move along the surface of the fixed block through moving the power-assisted plate to one side until the clamping block leaves the clamping groove, and after the fixing effect between the fixed block and the connecting block is canceled, the resistance plate can be easily taken down, so that the resistance plate can be maintained and replaced conveniently, but most of locking devices are inconvenient to adjust the locking mechanism when in use, after long-time use, the locking mechanism is worn and worn greatly, and the locking effect cannot be guaranteed.
