Description

Technical Field

[0001] This invention relates to the field of elevator components, specifically to a roller guide shoe testing device. Background Technology

[0002] Roller guide shoes are key mechanical devices in elevator systems used to guide and stabilize the car (or counterweight) as it moves vertically along the guide rails. They are typically installed at the top and bottom of the car or counterweight and work in conjunction with the guide rails. In taller buildings, because the guide rails are 2-5 meters long, they need to be spliced ​​together in multiple sections to achieve sufficient length. During this splicing process, due to the excessive length, uneven surfaces such as steps can easily occur at the splicing points. Especially with increased usage time, the guide rails are prone to different offsets in each section due to changes in external temperature (mainly expansion and contraction), external pressure applied by the elevator, and loosening of some fasteners. Verticality cannot be well guaranteed, and the roller guide shoes will also be affected accordingly.

[0003] Whether in the design of structural improvements or in the production of stable production, roller guide shoes require wear testing. The applicant's prior authorized patent CN113511574B (authorization date: May 14, 2024) discloses a solution that replaces the rubber layer of the roller with a synchronous belt that can be independently processed and replaced. Although this achieves better processing benefits, it also reduces the connection strength between the rubber layer and the roller (synchronous belt and roller). In use, more rigorous tests are required in addition to rubber layer wear to obtain the service life of the synchronous belt under uneven and discontinuous external force and whether it will detach from the roller after wear when pulled by external force.
