Railway hydraulic steel rail stretcher
The invention relates to the technical field of steel rail stretching and further discloses a railway hydraulic steel rail stretcher. The stretcher comprises an iron seat. According to the invention,the traditional wedging clamping is changed into the existing vertical pressing clamping, so the interior of the iron seat is completely vacated in the direction of the steel rail; in this way, the length of an existing clamping iron block can be increased. Meanwhile, due to the design of the whole structure, the length of the iron seat in the vertical direction is increased; compared with the original scheme, the contact surface of the clamping iron block and the steel rail can be greatly increased by combining the two aspects; therefore, the bearing force of the clamping iron block is increased; meanwhile, due to the design, the clamping iron block and the steel rail are in direct static friction contact in the working process, the sliding friction process does not exist, and the possibility of sliding friction does not exist either, so the clamping iron block can directly, completely and stably clamp the steel rail through force of the hydraulic cylinder, and therefore the functionof the stretcher is better achieved.
本发明涉及钢轨拉伸技术领域，且公开了一种铁路液压钢轨拉伸器，包括铁座，该铁路液压钢轨拉伸器，改变传统的锲合夹持改为现有的直压夹持，使得铁座内部在钢轨方向上是完全空出的，这样就可以使得现有的夹持铁块的长度增长，同时由于整个结构的设计将铁座在垂直方向的长度增加，结合两者可以使得夹持铁块与钢轨的接触面相比原有的方案大大增加，从而增加夹持铁块的承压力，同时这样的设计在工作时夹持铁块与钢轨之间直接就是静摩擦接触，不存在滑动摩擦的过程，也就也不存在滑动摩擦的可能，这样接触液压缸的力就能够直接的完全稳定得使得夹持铁块夹住钢轨，从而更好的实现拉伸器的作用。
