提出了一种新型的螺栓式钢轨防爬器，改变了穿销式防爬器的紧固方式。通过分析防爬器的受力，推导出防爬力的计算公式，并对其防爬性能进行了室内对比试验和现场试铺。结果表明：螺栓式防爬器的防爬力大于穿销式防爬器，且易于安装、拆卸，减少了轨道爬行和养护维修工作量，具有显著经济效益。 A new type of bolt-type rail anti-climbing device is proposed, which changes the fastening method of the wear-through type anti-climbing device. By analyzing the force of the anti-climbing device, the formula for calculating the anti-creeping force is deduced, and the comparison of the anti-creep performance of the anti-climbing device and the on-site test shop are carried out. The results show that the bolt-type anti-climbing device has a greater anti-climbing ability than the wearing-type anti-climbing device, and is easy to install and disassemble, thus reducing the crawling and maintenance workload of the railway track, and has significant economic benefits.
