[0002] Sleepers, also known as sleepers, are also a kind of railway accessories, but the material used is not only wood, so it is more scientific to call them sleepers. Sleepers must not only support the rails, but also maintain the position of the rails, and also transfer the huge pressure transmitted by the rails to the roadbed. It must have a certain flexibility and elasticity. When the train passes, it can deform appropriately to buffer the pressure, but it must be restored to its original state as much as possible after the train passes. Sleepers are a very important component in railway construction. Its main function is to support and fix the rails to the correct position and height to ensure the safety and stability of the train. Specifically, sleepers can play the following roles: Support rails: Sleepers are the main components supporting the rails. The rails need to be completely placed Above the sleepers to maintain the correct position and height; Fix the rails: The sleepers can be fixed to the rails by fixing screws or clamps to ensure that they are not easy to move, deform or crack, so as to ensure the smooth operation of the train on the railway; Disperse the load: When the train passes, the rails and sleepers will be under heavy pressure. If they only rely on the rails for support, it is easy to cause damage to the rails and the roadbed. The sleepers can evenly distribute the load of the train to the roadbed to protect the integrity of the roadbed and the railway line; Absorb shock: The sleepers can absorb part of the impact and vibration of the train passing, and reduce the damage to the railway caused by the train. During the installation and setting process of the sleepers, the sleeper fixing device is required to assist the placement and fixation of the sleepers.
