The performance of track platen is still good
The track plate manufacturer understands that the rectangular groove of the elastic composite rubber pad rail plate in the direction of the section of the direction plate reduces the total lateral deformation of the plate, and makes up for the damage of the extrusion deformation to the rubber plate. Due to the treatment of steel plate, its structure is reasonable. After 2 million times of fatigue performance tests to maintain good performance. Therefore, even after a long time of use, the pillow will not be damaged. Since the elastic composite rubber pillow is installed between the guide rail and the crane, it not only increases the friction force and makes the rail difficult to move, but also eliminates or reduces the uneven length of the gap along the rail and the crane beam. Thus, the stress state of the clamping bolt is improved. HDGY-TD series products are used for elastic fixed connection of rail beam of railway concrete crane. The upper wear of rail is reduced, the influence of crane on crane beam is reduced, the wear of crane wheel edge is reduced, and the noise is reduced. The cross section of the elastic composite rubber pad is somewhat convex in the middle, so that the force is reasonable. The small rectangular convex bar on the plate is easy to deform, which not only makes the pillow easy to contact with the track, but also increases the elasticity of the pillow. It acts as a damping. Long elliptical holes are designed in the body of the board to adjust the board.
Track plate has slope hole and block, fastening can avoid plate crowding. It is convenient for the horizontal adjustment of crane track installation or overhaul. The rail plate is attached to the crane beam, not loose, not easy to carry the crane beam. The symmetric roller has a wedge structure in the section direction, which limits the left-right crowding of the track. The rail is a pair of gantrail plates, the bracket near the bottom should be fixed, and the clamp can be adjusted laterally. The rubber block protects the plate bolts from loosening or breaking due to the upward lifting force of the rail. When a crane walks on a rainy day, it runs the foundation of rainwater on the ground. Since water is incompressible, it will be pushed out, the water method and extrusion repeated, causing soil wear and erosion. For this problem, the concrete foundation can be protected by laying steel rails and steel pads on the clay surface.
