AI Technical Summary

Technical Problem

Existing elevator locking devices are difficult to adjust after prolonged use, resulting in significant wear and tear on the locking mechanism and compromising locking effectiveness.

Method used

The elevator uses electromagnets and Hall effect sensors to monitor its speed. The energization and de-energization of the electromagnets control the thrust of the fixed blocks. Locking is achieved by combining a compression spring and a rotating shaft. The nut on the connecting rod adjusts the spring tension. The quick-release mechanism facilitates the replacement of the friction blocks.

Benefits of technology

It enables real-time monitoring and locking of elevator operating speed, reduces the risk of locking failure due to wear, and improves the adjustment and maintenance efficiency of the locking mechanism.

Abstract

The utility model relates to the technical field of elevator car locking, and discloses an elevator car locking device which comprises a device base, a locking frame is installed on the upper surface of the device base, a locking mechanism used for locking a car is arranged on one side of the locking frame, a driving mechanism used for driving the car is arranged on the side wall of the locking frame, and the driving mechanism is arranged on the side wall of the locking frame. A quick release mechanism for replacing the locking mechanism is arranged on one side of the driving mechanism; the locking mechanism comprises an electromagnet, the electromagnet is fixed to one side of the locking frame, and the two ends of the electromagnet are both connected with fixing blocks. The electromagnet on the locking frame stops electrifying, so that the fixed block loses external thrust, under the action of the pressure spring, the fixed block is pushed to move inwards, under the action of the rotating shaft, the friction block in the movable piece is in contact with the outer surface of the fixed wheel, the fixed wheel is fixedly locked, and then the lift car is locked.
