In fact, the track clamp, also known as the fishplate, is a railway accessory and an important component of railway turnouts. If there is a problem with the track clamp, it will inevitably affect the safety of railway turnouts. Therefore, during normal operation of railway turnouts, it is necessary to regularly inspect and maintain the track clamp. If damage is found during the inspection of the track clamp, it needs to be repaired or replaced with a new one. In use, the difference between the length of the track and the weight of four and six holes. Because different tracks have certain requirements for the quality of road clamps, the difference between the two types of holes and weight is also the difference between the two types of holes. The railway track is the path of the train, and it is connected by different railway components. The components that connect the tracks are particularly important.

Track clamp is a very important railway accessory in railway transportation. Its main function is to connect the influence of two tracks. Due to the special nature of railway transportation, the separability of railway transportation is created. Therefore, plywood must be used to play a loose connection at the rail joint to prevent the track and ensure the stability of the track. It can be continuously tracked by locomotives under the force of vehicle bearings. There are many ways to connect railways with tracks, and the traditional method is to fix the rails on approximately 20 meters of steel rails with a connection (also known as a seam) between the rails. It is a steel plate approximately 60 centimeters long, with 4 to 6 steel bolts at each end, used to keep small holes on the railway. The steel rails between them, approximately 6 millimeters wide, are called expansion joints. Road clamps are an important component of rail transit, with tight connections that ensure the safety of trains and pedestrians.
