AI Technical Summary

Technical Problem

Traditional railway subgrade reinforcement devices lack elastic buffer structures and dynamic damping adjustment mechanisms, which cannot effectively disperse impact forces, resulting in poor stability. Furthermore, they cannot automatically adjust the support height and stress state according to the terrain, thus affecting the reinforcement effect.

Method used

It adopts a combination of components such as buffer pads, valves, magnetic blocks, rubber pads, counterweights, and sliding discs. The buffer pads reduce the impact force, the valves regulate the fluid state, and the counterweights adjust the state of the device, thereby achieving dynamic stability and terrain adaptability.

Benefits of technology

It improves the stability and service life of railway subgrade reinforcement devices, enhances adaptability to different terrains, ensures close contact between the device and the subgrade, and improves the reinforcement effect.

Abstract

The application relates to the technical field of railway construction and maintenance, in particular to a railway roadbed reinforcing device, which comprises a supporting leg, a clamping block is fixedly connected to the middle of the upper end of the supporting leg, and a ring-shaped ring is fixedly connected to the middle of the lower end of the supporting leg. The device can be impacted by external force or vibration, the buffer pad can first play a buffering role, the impact force on the device is reduced, meanwhile, under the synergistic action of the magnetic suction block and the rubber pad I, the valve can control the fluid flow in the supporting column I, when a larger vibration is generated, the valve can be moved due to the vibration, the state of the internal fluid is adjusted, the influence of the vibration is further buffered, the technical problem that the railway roadbed reinforcing device is easily impacted by external force and vibration and has poor stability in a complex environment can be solved through the buffer pad and the valve, so that the stability of the device is improved, and the service life of the device is prolonged.
