Damping steel base plate with anti-corrosion coating for railway track base plate

Abstract

The invention discloses a damping steel base plate with an anti-corrosion coating for a railway track base plate. The base plate comprises a rail base plate body, a damping steel base plate body is arranged on the rail base plate body, the damping steel base plate is connected with springs, the damping steel base plate body is connected to the rail base plate body through rail threaded cylinders and fixed threaded bolts, the damping steel base plate body is connected with a base wood plate, the damping steel base plate body internally comprises a steel plate, a tin alloy layer, a conductive coating and a rubber layer, and an insecticidal layer adheres to the middle of the base wood plate. The damping base plate is made of a steel material, the tin alloy layer is electroplated, the conductive coating is smeared, the service life is prolonged, and the corrosion is prevented; a damping base plate is arranged to be arc-shaped, the springs are arranged in the damping base plate to achieve damping, and the threaded cylinders are arranged to prevent fixing threaded bolts from falling off; and an insecticidal layer is arranged in the base wood plate so that insect erosion is prevented.

Description

Technical field [0001] The invention belongs to the technical field of railway tracks, and in particular relates to a damping steel backing plate with anti-corrosion coating for railway track backing plates. Background technique [0002] When the railway track is installed again, a backing plate will be installed under the track to absorb the vibration of the track. The existing shock absorption device is generally made of rubber, so that the backing plate can be stressed. When damage occurs, there are still various problems with various backing plates on the market. [0003] For example, the elastic backing plate disclosed in the authorized announcement number CN1317453C, although the damping body is added to the elastic backing plate, the damping body is deformed, and the vibration energy transmitted by the track is converted into heat energy, thereby greatly improving the elastic backing plate The performance of vibration reduction, vibration isolation, and noise reduction impr...

AI Technical Summary

Problems solved by technology

[0002] When the railway track is installed again, a backing plate will be installed under the track for shock absorption of the track, and the existing shock absorbing devices are generally made of rubber, so that the backing plate can withstand stress. Damage occurs from time to time, but there are still various problems with various backing plates on the market

[0003] For the elastic backing plate disclosed by CN1317453C as the authorization announcement number, although it has realized that the damping body has been added in the elastic backing plate, the damping body produces deformation, and the vibration energy transmitted by the track is converted into heat energy, thereby greatly improving the elasticity of the elastic backing plate. The performance of vibration reduction, vibration isolation, and noise reduction improves the comfort of the train when it is running. Due to the reinforcement, the life of the backing plate is improved, but it does not solve the problem that the service life of the existing backing plate is relatively short, and the The single damping structure makes the backing plate easily damaged when it is stressed, and there is no base board on the damping backing board, so the backing board will be directly impacted by the track, and the base board is prone to insect erosion and other problems. Therefore we propose a damping steel backing plate with an anti-corrosion coating for railway track backing plates
