Railway insulation gauge pull rod
The invention relates to the technical field of railway track reinforcing equipment, in particular to a railway insulation track gauge pull rod which comprises a rod body and two clamping mechanisms, the rod body is composed of two screws and an internal thread sleeve, the two ends of each screw are provided with a main thread and an auxiliary thread, the main threads are connected with the clamping mechanisms, and the auxiliary threads are connected with the internal thread sleeves. The clamping mechanism comprises an iron clamp, a fastening nut, a spring ring and a flat gasket. The surface of the rod body and the surface of the clamping mechanism are coated with an insulating coating with the uniform thickness, and a high-strength epoxy resin injection molding material is thermally injected between the screw rod and the internal thread sleeve. The insulating anticorrosive coating and the high-strength injection molding material are sprayed on the surface layer of the gauge pull rod, so that the service life of the gauge pull rod is prolonged.
本发明涉及铁路轨道加强设备技术领域，具体为一种铁路绝缘轨距拉杆，包括一根杆体和两组卡紧机构，杆体由两根螺杆和一根内丝套管组成，螺杆两端有主螺纹和副螺纹，主螺纹连接卡紧机构，副螺纹连接内丝套管。卡紧机构包括铁卡、紧固螺母、弹簧圈和平垫片。杆体和卡紧机构的表面涂覆一层厚度均匀的绝缘涂层，螺杆和内丝套管之间热注入高强环氧树脂注塑材料。本发明通过在轨距拉杆的表层喷涂绝缘防腐涂层和高强注塑材料，增强了轨距拉杆的使用寿命。
