The double head screw spike manufacturer is the key to making train turns and is laid on trains, high-speed trains, subways and urban tracks. The type of double head screw spike manufacturer varies depending on the region and place of use. Many double head screw spike manufacturers are installed outdoors for tracking together. If the site environment, weather and other factors are affected for a long time, it is easy to damage the double head screw spike manufacturer. Therefore, it is necessary to maintain the double head screw spike manufacturer regularly. Let's follow the double head screw spike manufacturer to find out the common causes of damage to the double head screw spike manufacturer.

Under normal operating conditions, the influence of the train wheel pair on the rail is complex, and the size, direction and position of the external action are uncertain, which is very different from the static operating conditions. Under the action of load and temperature, the rail produces compression, elongation, bending, torsion, collapse, wear and crack and other complex deformation. The internal force of the rail is more complicated, because the temperature changes quickly, the external force is large, often lead to the fracture of the rail.

Defects in the smelting process and harsh conditions in transportation and use can also cause rail damage. The double head screw spike manufacturer uses cut and curved rails for the base and sharp rails, and uses high manganese steel for the frog. The causes of force and destruction are more complex.

In the daily management of rail transit, crossing injury is usually divided into minor injury, developmental minor injury and serious injury. Due to the characteristics of light axle weight, single model, track structure and operating conditions, the damage types of urban rail transit have their own characteristics.

The double head screw spike manufacturer, after all, makes the train turn. In the process of turning, it is easy to be impacted by the train. After impact, parts are easy to loosen, thus affecting the normal use of the double head screw spike manufacturer. In order to reduce the damage of the double head screw spike manufacturer, the early installation and maintenance of the double head screw spike manufacturer is very important. At the same time, it is necessary to do some surface treatment and workmanship to avoid rust or failure of the double head screw spike manufacturer in use.
