Base plate with wear monitoring function and rail fastener
The invention, which relates to a tramcar, provides a base plate with a wear monitoring function. The base plate with the wear monitoring function comprises an elastic composite base plate and an external circuit. The elastic composite backing plate comprises a drag reduction layer arranged on the top side and an elastic layer arranged on the bottom side; the elastic layer is made of a conductivethermoplastic elastomer material; the drag reduction layer is made of an insulating polymer wear-resistant material; and at least one protrusion is arranged on the top side of the elastic layer and each protrusion is embedded into the drag reduction layer. One end of the external circuit is connected to the elastic layer, and the other end of the external circuit is used for being connected to a steel rail installed on the drag reduction layer; when the drag reduction layer is abraded and the steel rail makes contact with at least one protrusion, the external circuit, the steel rail and the elastic layer form a circuit loop, and an alarm device of the external circuit sends an alarm signal. The invention further provides a rail fastener. Therefore, on the basis of an improved base plate structure, the wear condition of the base plate can be monitored.
本发明涉及有轨电车，提供了一种具有磨损监测功能的垫板。该具有磨损监测功能的垫板，包括：弹性复合垫板，弹性复合垫板包括顶侧的减阻层和底侧的弹性层，弹性层由导电热塑性弹性体材料制成，减阻层由绝缘高分子耐磨材料制成，弹性层的顶侧设有至少一个凸起，每个凸起均嵌入到减阻层中；外接电路，外接电路的一端连接至弹性层，另一端用于连接至安装在减阻层上的钢轨；其中，当减阻层磨损并且钢轨与至少一个凸起接触，外接电路、钢轨和弹性层构成电路回路，外接电路的警报装置发送警报信号。本发明还提供了一种轨道扣件。本发明的目的在于：改进垫板的结构，以使得垫板的磨损情况可以被监测到。
