Sliding guide shoe assembly and elevator system

Abstract

The invention relates to the field of elevator accessories. In order to reduce the wear between the sliding guide shoe assembly and the guide rail, the invention provides a sliding guide shoe assembly, which includes a bracket, a shock absorbing device, a rotating connector and a shoe shell. A shock-absorbing layer made of shock-absorbing material is arranged between the tube and the outer shell. The shock-absorbing material has certain elasticity and deformation effects, so that the inner tube can be displaced relative to the outer shell. When the limiting shoe liner is subjected to the external force generated by the eccentric load, the shoe shell can rotate slightly in the plane perpendicular to the bottom of the groove to balance the external force, so that the sliding guide shoe assembly will not occur to a large extent. offset to reduce wear between the sliding guide shoe assembly and the guide rail. Through the transmission of force, the force acting on the limit shoe liner is transmitted to the inner tube, and the inner tube moves relatively, causing elastic deformation of the shock-absorbing layer, converting mechanical energy into elastic deformation energy of the shock-absorbing layer, and playing a good damping effect. Shock effect, simple structure and low cost.

Description

technical field [0001] The invention relates to the field of elevator accessory manufacturing, in particular to a sliding guide shoe assembly. The invention also relates to an elevator system comprising the sliding guide shoe assembly. Background technique [0002] The guidance system of an elevator usually consists of guide shoes and vertical guide rails. The guide shoes cooperate with the guide rails to keep the car and the counterweight moving in the vertical direction. During movement, there are forces between the rail and the shoe. For example, on the one hand, the acceleration or deceleration of the elevator will generate a vertical force along the direction of the guide rail; on the other hand, the asymmetric load in the car will cause a normal force acting vertically on the track surface of the guide rail. The above-mentioned force is likely to cause local contact (line contact or surface contact) between the guide shoe and the guide rail, causing friction and wea...

AI Technical Summary

Problems solved by technology

The above-mentioned force is likely to cause local contact (line contact or surface contact) between the guide shoe and the guide rail, which will cause friction and wear on the surface materials of the guide rail and the guide shoe, thus adversely affecting the performance and service life of the elevator.
