Abstract

The invention discloses a hydraulic stepless automatic settlement compensation device for a transition section. The hydraulic stepless automatic settlement compensation device for the transition section comprises an oil cylinder barrel substrate, a dust cover and seal rings. The cylinder part of a plunger support frame is arranged in a cylindrical hole of the oil cylinder barrel substrate; the dust cover is arranged between the plunger support frame and the oil cylinder barrel substrate; the lower part of the cylindrical hole of the oil cylinder barrel substrate is an oil chamber; the bottom end of the plunger support frame is provided with a check valve; the outer cylinder of the plunger support frame is provided with a ring groove and a radial hole; both ends of the radial hole are respectively communicated with the ring groove and a cylindrical oil pool; breathing holes are formed in the side face of the upper end of the plunger support frame; a waterproof and dustproof blank cap is arranged in a cylindrical hole of the upper end of the plunger support frame; the oil cylinder barrel substrate is fixedly arranged on a subgrade railway ballast; the plunger support frame and a sleeper are connected into a whole by pressing blocks through bolts. The hydraulic stepless automatic settlement compensation device for the transition section disclosed by the invention has the characteristics that the structure is simple, working is reliable, and the like, and can be automatically adjusted, and not only can be used for solving the irregularity problem caused by differential settlement of a line but also can be used for easing impacts of locomotive wheels to steel rails by utilizing the elasticity of liquid.

Description

technical field [0001] The invention relates to a hydraulic stepless automatic subsidence compensation device for a transition section. Background technique [0002] The railway line structure is composed of lines (subgrade lines), bridges, tunnels, and stations. The track structure of the line can be laid with ballasted tracks and ballastless tracks according to the differences in railway grades and technical standards. The stiffness of different line structures is significantly different, causing the displacement response of the rail surface to be inconsistent when the train passes. At the same time, the foundation settlement of different structures is not uniform, and deformation is easily generated near the transition point, resulting in bending of the rail surface. When the train passes by at high speed, the dynamic interaction between the vehicle and the line is intensified, causing serious irregularities on the track surface, accelerating the deterioration of the line...
