Railway ballast processor suitable for narrow operation face

Abstract

A railway ballast processor suitable for a narrow operation face comprises a carriage (1); bogies (5 and 16) are arranged at the two ends below the carriage (1); a front cab (4) is installed at the front end above the carriage (1); an annular chain excavation mechanism (9) is arranged in the middle of the carriage (1); a main track raising and lining device (8) is installed on the lower portion of the carriage (1) and in front of the annular chain excavation mechanism (9); the annular chain excavation mechanism (9) comprises a sliding column mechanism (19) connected with a supporting beam (23); one end of the supporting beam (23) is connected with an ascending guide groove (27); the other end of the supporting beam (23) is connected with a descending guide groove (24); an excavation chain (25) is installed in the ascending guide groove (27), the descending guide groove (24) and a bottom beam and is annular. The excavation guide grooves and the bottom beam do not need to be installed on the excavation device before operation or dismounted after operation, the influence that tunnel drainage ditches on the two sides of a roadbed slope occupy the transverse construction area during manual operation is avoided, the mechanical operation of the narrow operation face in a railway tunnel is created, and the telescopic bottom beam can also be adjusted.

Description

technical field [0001] The invention relates to a ballast processing machine for railway track bed maintenance, which belongs to railway maintenance engineering vehicles. Background technique [0002] Due to the characteristics of poor visibility, strong sealing and narrow internal space in railway tunnels, mechanized maintenance operations in railway tunnels are greatly restricted. According to the degree of difficulty, the treatment of ballast in railway tunnels is the biggest problem. Railway tunnels Internal ballast treatment is a blank spot and blind spot in my country's line mechanized major and medium maintenance operations. Ballast treatment in railway tunnels has become the biggest bottleneck restricting mechanized maintenance. Therefore, the design and development of a machine that can handle ballast in the narrow working surface of the railway tunnel has become an urgent need to solve the ballast treatment in the railway tunnel of our country, and the excavation de...
