Analysis and summary of the reasons for the fracture of the track pressure plate

The track pressure plate is an accessory used on the rail, which mainly has a certain fixed effect on the track. If the quality of the track pressure plate is not good and it is greatly impacted by the train during use, it will affect the normal use of the track pressure plate. Although the track pressure plate is not a big piece in the track system, if it is of poor quality, when it is used, the trains on the track will often bring a huge impact on it, which will affect the normal operation of the entire line in the long run, and the belt will be damaged. certain security risks.

In the cold winter, due to the low temperature, the use of various mechanical equipment will be affected to a certain extent, especially for railway track equipment, which is composed of many cast iron parts. The maintenance of accessories will directly affect the normal operation of the train, especially when it snows. If the snow on the rails is not removed in time, when the snow freezes, it will cause the train to run on the rails.

Track pressure plate is a common accessory used on rails. It is generally used in conjunction with hexagonal bolts or embedded bolts. Its main function is to fix the rails, sleepers and ground. In practical applications, the rail platen has many advantages, showing stability and durability. When the crack starts from the top of the pressure plate, because the tensile stress received is small, the crack initiation and expansion are more affected by the material; when the pressure plate starts to crack from the lower mouth, the tensile stress is larger, and the crack initiation and expansion are affected by the material. The load has a bigger impact. Season is also an important factor for platen failure. Judging from the situation of on-site use, the damage of the pressure plate in winter is significantly higher than that in other seasons.

The fracture of the rail pressure plate in winter may be related to the change of the rail joint in winter. The increase of the rail joint in winter will increase the tensile stress of the rail pressure plate, and this additional stress will increase the number of failures of the rail pressure plate. When purchasing a rail pressure plate, it is necessary to ensure the stability and reliability of the rail pressure plate, and specific problems must be analyzed in detail, and the corresponding type of rail pressure plate should be selected according to different track properties. Some track clamps have good insulating properties and are very easy to use.
