The function of rail joints in railway turnout
the rail joints, also known as the fish plates, are a railway accessory and an important part of the railway turnout. If there is a problem with the rail joints, it will inevitably affect the driving safety of the railway turnout. Therefore, when the railway turnout is running normally, it must be Regular inspection and maintenance of the rail joints should be carried out. If the rail joints are found to be damaged during the inspection of the splint, it needs to be repaired or replaced with a new joint bar. In use, the difference between the track length and the weight of four and six holes. Because different tracks have certain requirements on the quality of the road plywood, the difference between the two types of holes and the weight is also different between the two types of holes. The rails are the roads of the train, and the rails are connected by different railway components, and the components that connect the tracks are especially important.
The rail joint bar is a very important railway accessory in railway transportation. Its main function is to connect the influence of two tracks. Due to the particularity of railway transportation, the separability of railway transportation is created, so plywood must be used for loose connections in the rail joints. , to prevent the track to ensure the stability of the track can be continuously tracked by the locomotive when there is the force of the vehicle bearing. There are many ways to connect the rail to the track, the traditional method is to fasten the rail to about 20 meters of steel rail with a connection (also called a seam) between the rails. It is a steel plate about 60 cm long with 4 to 6 steel bolts on each end to hold the small holes in the rail. The rails between the rails, about 6mm wide, are called expansion joints. The rail joints are an important part of rail transit, and their tight connection ensures the safety of trains and pedestrians.
