[0002] Elevator guide rails are elevator components consisting of steel rails and connecting plates. They are divided into car guide rails and counterweight guide rails. They are divided into three types according to the cross-sectional shape: T-shaped, L-shaped and hollow. While playing a guiding role, the guide rails also bear the impact force of the car and elevator during braking, the impact force of the safety clamp during emergency braking, etc.

[0003] When the elevator guide rail is in operation, it is equipped with a guide shoe structure. When the elevator is running, the guide shoe structure will repeatedly rub against the surface of the guide rail. Long-term friction will cause wear on the surface of the guide rail, and excessive wear will also cause looseness between the guide shoe structure and the guide rail, thereby reducing the safety of the guide rail. For this reason, an elevator guide rail structure with efficient operation is proposed. Utility Model Content
