Leveling anti-slip device for car elevator

Abstract

The invention discloses a flat layer anti-slip device for a lift car elevator. The flat layer anti-slip device structurally comprises a power line, a traction wheel transmission disc, a drive shaft, an assembly hole and a brake wheel, the traction wheel transmission disc is of a circular structure and is installed at the upper end of the brake wheel in a buckled manner, the power line is arrangedon the side face of the brake wheel, and the drive shaft is of a circular structure and is arranged at the middle portion of the traction wheel transmission disc in an embedded manner. The arranged brake wheel drives a main brake device through a driving mechanism to jack out a friction device, a transmission body is braked, the arranged main brake device drives two limiting mechanisms to limit and fix brake shoes during the movement process, quick reset of the brake shoes is avoided, an auxiliary device is driven by a limiting push rod to conduct auxiliary braking on the interior of the driveshaft in the movement process, the accuracy of lift car elevator stop layers is effectively improved, braking can be limited during flat layers, safety is improved, and passengers feel secure in theuse process.

Description

technical field [0001] The invention relates to the field of car elevators, in particular to a leveling anti-slip device of the car elevator. Background technique [0002] The principle of the car elevator is a pulley block, and the two ends of the pulley are respectively hung with the car and the counterweight by wire ropes. The use of the car elevator relies on the motor to drive the traction sheave to rotate, which drives the steel wire rope to move, thereby driving the position of the car and the counterweight to change. The movement of the above steel wire rope is transmitted by the friction force between the traction sheave and the steel wire rope. This friction The force is the traction force, and its magnitude is affected by factors such as the shape of the rope groove of the traction sheave and the thickness of the wire rope. The stop of the above-mentioned car elevator is to rely on the brake of the traction machine. The brake is composed of two clamps with fricti...

AI Technical Summary

Problems solved by technology

The outside of the traction wheel in the current technology is driven by the brake wheel cylinder to directly hold and brake the brake shoes. After long-term use, the brake pads on the brake shoes have reduced braking force due to wear, and there are no spare friction parts and Braking components, which greatly affect the safety of the elevator, reduce the sense of safety of passengers, and even cause major accidents
