AI Technical Summary

Technical Problem

Existing wheel stoppers are prone to damage, have a short lifespan, cannot adapt to different wheel conditions, are easy to tip over, lack sufficient safety, and have limited functionality, failing to assist in vehicle maintenance.

Method used

It adopts an adaptive structure with a 30° inclined guide rail and dual springs, and achieves elastic self-locking through the linkage of the tread contact joint and the tread contact device. Combined with high-strength metal materials and a slotted base plate design, it enhances stability and detection function.

Benefits of technology

It achieves precise adaptation to wheels of different diameters and wear conditions, avoiding wheel crushing damage, extending service life, improving safety and maintenance efficiency, and integrating wheel diameter detection function without the need for additional equipment.

Abstract

本发明提供了一种自锁式防滑止轮器及其使用方法与车轮轮径检测方法,该止轮器包括底面设钢轨匹配卡槽的底板,底板上固定中心支撑装置与防护板;中心支撑装置设有与底板成 30° 夹角的导轨,导轨上滑动装配的移动底座通过支撑臂杆铰接踏面接触关节,移动底座与弹簧止挡间压装压缩弹簧;底板还设有伸缩弹簧支撑的踏面贴合装置,常态下其表面低于踏面接触关节。车轮下压后,移动底座沿导轨下滑,踏面贴合装置自动贴合车轮踏面,二者形成弹性自锁。本发明可适配不同直径及磨耗状态的车轮,实现柔性止停,防滑可靠、无易损橡胶件、寿命长免维保,同时集成车轮轮径超限检测功能,无需额外工具即可直观判定轮径是否达标。
