The invention discloses a brake shoe adjusting device capable of preventing eccentric wear of a brake shoe, and relates to the field of brake shoe adjusting.The outer end of a brake shoe body is in butt joint with an adjusting movable preset shaft, and position movement is conducted through butt joint of the adjusting movable preset shaft and external preset conduction equipment; a built-in transverse guide groove is formed in the inner wall of the brake shoe body, a built-in detachable contact piece is installed on the inner side of the built-in transverse guide groove in a nested mode, and the inner end of the built-in detachable contact piece is fixedly connected with a first reset spring. According to the brake shoe adjusting device capable of preventing eccentric wear of the brake shoe, the positioning state of the lateral movable butt joint piece is adjusted in a self-adaptive mode through the auxiliary guide structure, centered type contact speed reduction work is conducted on a contacted wheel from the two sides, and the phenomenon that direct contact type speed reduction treatment cannot guarantee that the speed reduction wear eccentric shoe cannot be guaranteed is avoided; a movable wheel can stably decelerate according to different stress states in the high-speed working process, position deviation is prevented, and stable positioning type speed limiting work on the movable wheel is achieved through a contact brake shoe.
本发明公开了一种可防止闸瓦偏磨的闸瓦调节装置,涉及闸瓦调节领域,所述闸瓦本体的外端对接有调节活动预设轴,通过调节活动预设轴与外置预设传导设备对接进行位置活动;所述闸瓦本体的内壁开设有内置横向导向槽,且内置横向导向槽的内侧嵌套安装有内置可拆接触件,所述内置可拆接触件的内端固定连接有第一复位弹簧。该可防止闸瓦偏磨的闸瓦调节装置,通过辅助引导结构对侧向活动对接件的定位状态自适应调节,对接触的车轮从两侧进行居中式的接触减速工作,避免直接接触式的减速处理无法保证其减速磨损偏瓦的现象,让活动的车轮在高速工作的过程中可根据不同的受力状态稳定减速,防止位置偏差,实现接触的闸瓦稳定的对其进行定位式限速工作。
