Description

Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to a balancing structure of guide shoes on both sides of an elevator. Background Art

[0002] The car guide shoe is a device that allows the elevator car and counterweight to move up and down along the fixed guide rails, preventing the car and counterweight from twisting on the traction wire rope and deflecting or swinging under asymmetric loads. When in use, they are installed on the car and counterweight respectively, allowing the car and counterweight to move up and down in a straight line along the guide rails.

[0003] However, when guide shoes are installed on both sides of the car to guide and limit the position of the car, two sets of compensation chains are usually set between the counterweight side and the car to assist in balancing the elevator car. However, when the load-bearing weight inside the car is on one side, it will cause the car to shift, which will easily lead to excessive wear of the guide shoes installed on one side of the car. There is a deficiency in that there is no measure to balance and prevent uneven wear of the guide shoes on both sides of the car.

[0004] Now, a new type of elevator guide shoe balancing structure is proposed to solve the above-mentioned shortcomings. Utility Model Content
