A common fastener on rails
Sep 05, 2022| A common type of fastener on the rail is to fix the sleeper of the rail with the concrete, and the rail pressure plate can reduce the large impact on the rail during the operation of the train. The rail pressing plate not only has various styles and specifications, but also has higher quality requirements in use. In order to better exert its tightness, the rail pressing plate is often used together with the pressing block.
Track pressure plate
The rail pressing plate pressing block adopts an adjustable combined rail pressing plate, which can overcome the failures of the traditional rail pressing plate in use. The traditional pressing plate is often used to press the rail directly with the rail steel. Reliable contact, some pressure plates can no longer be adjusted in the horizontal direction after installation, so after normal load or thermal expansion and contraction caused by longitudinal movement of the track, it is easy to wear, causing the bolts of the pressure plate to loosen and the pressure plate to rotate, causing the surface of the track to wear. And gnawing on the rail, which will cause the rail to break in severe cases, which will also affect the wear of the main engine wheels and the damage to the drive mechanism.
The bottom of the rail is laid with a rubber compound backing plate, and the rail is pre-compressed, which can prevent the rail from generating local rail lifting force during the movement of the large wheel pressure, resulting in loose bolts and affecting the damage of each device. It can also allow the rail to move longitudinally when the rail is heated and contracted, without causing wear to the pressing plate rail, and can keep the rail bottom surface of the rail in close contact with the rubber composite backing plate laid on the rail.
