Stopping device of elevator car

Abstract

The invention discloses a stopping device of an elevator car, and belongs to the technical field of elevators. The elevator car comprises a car chassis and an elevator car body. The left side and the right side of the car chassis are matched with shaft guide rails through guide shoes respectively, the shaft guide rails are fixed to shaft guide rail frames, and the shaft guide rail frames and the shaft wall are fixed. The elevator car body is arranged on the car chassis. The stopping device comprises rod bolt locking plates, rod bolt mechanisms, rod bolt driving mechanisms and rod bolt position signal collectors, wherein the rod bolt locking plates are fixed to the shaft guide rail frames, the rod bolt mechanisms are arranged at the positions, corresponding to the rod bolt locking plates, of the car chassis, the rod bolt driving mechanisms are electrically connected with an electrical control device of an elevator and arranged on the car chassis in the state of being connected with the rod bolt mechanisms, and the rod bolt position signal collectors are arranged at the positions, corresponding to the rod bolt mechanisms, of the car chassis and electrically connected with the electrical control device. The operation convenience can be shown, safety can be guaranteed, and serious accidents can be prevented.

Description

technical field [0001] The invention belongs to the technical field of elevators, and in particular relates to a brake and stop device for an elevator car, which is used to securely lock the elevator car on the guide rail frame of the hoistway before inspection and maintenance personnel are ready to enter the hoistway for the operation of the elevator car to carry out inspection and maintenance. , in order to protect the personal safety of inspectors. Background technique [0002] The technical information about the braking device of the elevator car can be seen in the published Chinese patent literature, typically such as the "elevator braking device" recommended by the invention patent authorization announcement number CN101700850B and the "a kind of non-stop device" provided by the authorization announcement number CN102275792B Braking device and working method of the elevator car in the machine room". [0003] The above-mentioned CN10170085B realizes the brake or relea...

AI Technical Summary

Problems solved by technology

[0005] As can be seen from the above description, although the aforementioned two patents have the same effect on stopping the elevator car, they have the following disadvantages: one, due to the need to rely on manual operation, the operation is cumbersome; The stop device is located in the well, so it needs to be operated by the inspection personnel after entering the well, so the operation is more inconvenient; third, it is not enough to reflect sufficient safety, because if the inspection personnel enter the well and check the stop device Even if the elevator car slips or slides in a very short period of time before the operation, the consequences are self-evidently very serious. It is in the braking state behind the elevator car, so it is difficult to guarantee absolute safety; fourth, it is not enough to force the braking device to play a role, because when the inspection station personnel enter the hoistway and are busy with inspection, they neglect to control Stop device operation, then the stop device is useless
