Real-time track bed mechanical mass state detection system based on tamping wagon

Abstract

The invention discloses a ballast bed mechanical quality state real-time detection system based on a tamping wagon and relates to the technical field of ballast bed quality detection. A mechanical quality state of a ballast bed can be detected in real time in the track lining process and the tamping process, detection precision is improved while a large amount of manpower and material resources are saved, and a follow-up operation mode of a large machine can be guided in real time according to the detection result. The detection system comprises a track lining device and two tamping devices arranged side by side, wherein the track lining device comprises two track lining oil cylinders, the track lining oil cylinders are communicated with a hydraulic control system through an oil inlet pipeline and an oil return pipeline; the oil inlet pipeline and the oil return pipeline are each provided with a pressure sensor used for detecting the pipeline pressure; the tamping device comprises two pairs of tamping assemblies arranged on the two sides, each tamping assembly comprises a pair of tamping pick arms and two pairs of tamping picks, dynamic force sensors are arranged at joints of the tamping pick arms and the tamping picks, and the dynamic force sensors can detect transient dynamic downward insertion force generated when the tamping picks are inserted into the ballast bed.

Description

technical field [0001] The present application relates to the technical field of ballast bed quality detection, in particular to a real-time detection system for the mechanical quality state of the ballast bed based on a tamping vehicle. Background technique [0002] The maintenance of ballasted lines in our country has developed from manual work and small-scale road maintenance machinery to large-scale road maintenance machinery opening "skylights" for line maintenance. The main operation methods of large-scale road maintenance machinery are tamping and stabilization: tamping operation can increase the density of the ballast bed under the pillow and improve the elasticity of the ballast bed; stabilization operation can make the ballast bed reach a stable state quickly and shorten the speed limit time of the train. However, under the impact and disturbance of the tamping pick, the ballast is easily broken, and the gradation of the ballast changes, thereby reducing the streng...

Problems solved by technology

However, under the impact and disturbance of the tamping pick, the ballast is easily broken, and the gradation of the ballast changes, thereby reducing the strength and stability of the ballast bed.

Most of the large-scale machine operations in my country at the present stage are arranged according to experience and adopt the same operation mode. However, the mechanical quality of the ballast bed in different lines or even in different sections of the same line is different. Therefore, the maintenance and repair effect of large-scale machine operations Not good, the shelf life of the line is short, and the effect of the large machine tamping operation needs to be improved
