Locking clamp, steel rail vibration absorber and installation method of steel rail vibration absorber
According to the locking clamp, the steel rail vibration absorber and the mounting method of the steel rail vibration absorber, the supporting frame of the U-shaped structure is matched with the positioning block to press the vibration absorbing wedge block on the steel rail, so that the clamping force of the locking clamp is stable and can be kept for a long time, and the problems that the clamping force of an elastic clamp cannot be kept stable for a long time, loosening occurs, the clamping force is insufficient, and even fracture failure occurs are solved; the vibration absorption and noise reduction effects, safety and stability are guaranteed, the overhaul and maintenance frequency can be reduced, and manpower and corresponding cost are saved. Due to the fact that the locking clamp only comprises the integral support and the two locking assemblies, during installation, the support only needs to stretch into the bottom of the steel rail, the support is rotated to form a surrounding structure on the steel rail, then the two locking assemblies are screwed to enable the positioning block to press the vibration absorption wedge block, and therefore installation is convenient, the labor intensity of workers is low, and later maintenance is more convenient. In addition, at least four elastic clamps are needed for fixing the pair of vibration absorption blocks, but only two locking clamps are needed for fixing the pair of vibration absorption blocks, so that the installation time is shorter, and the overall cost is lower.
本发明提供一种锁紧夹、钢轨吸振器及其安装方法，锁紧夹采用U型结构的支架配合定位块将吸振楔块压紧在钢轨上，因此其夹持力稳定且可长期保持，避免了弹性夹夹持力无法长期保持稳定，出现松脱、夹持力不足，甚至断裂失效的问题，保障了吸振降噪效果及其安全性、稳定性，且能够降低检修维护的频率，节省人力及相应的成本。由于锁紧夹仅包括一个整体支架及两组锁紧组件，安装时仅需将支架伸入钢轨底部，转动支架对钢轨形成包围结构，再拧紧两组锁紧组件使定位块压紧吸振楔块，因此安装便捷，工人的劳动强度低，且后期维护也更方便。此外，固定一对吸振块需要至少4个弹性夹，而采用本发明的锁紧夹则仅需两个，因此安装时间更短，总体成本更低。
