Abstract

An excavation device suitable for operation on a narrow operation face of a railway tunnel comprises a sliding column mechanism (2) connected with a supporting beam (1); one end of the supporting beam (1) is connected with an ascending guide groove (6); the other end of the supporting beam (1) is connected with a descending guide groove (3); the bottom ends of the ascending guide groove (6) and the descending guide groove (3) are connected together through a bottom beam (4); an excavation chain is installed inside the ascending guide groove (6), the descending guide groove (3) and the bottom beam (4) and is annular; the ascending guide groove (6) and the descending guide groove (3) are symmetrical with respect to the longitudinal central line of the supporting beam (1); the ascending guide groove (6), the descending guide groove (3), the bottom beam (4) and the supporting beam (1) are in a hexagon shape in the transverse plane. The excavation guide grooves and the bottom beam do not need to be installed before operation or dismounted after operation, only a track section is disconnected, and thus the excavation efficiency is greatly improved, the mechanical operation of the narrow tunnel is created, the technical problem troubling the national railway tunnel maintenance industry for many years is solved, and the manual labor intensity is greatly relieved.

Description

technical field [0001] The invention relates to an excavating device, in particular to an excavating device capable of operating in narrow working surfaces such as railway tunnels, and belongs to the technical field of railway machinery design and manufacture. 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 ...
