Abstract

The invention discloses a tunnel track-bed ballast replacing machine which comprises a machine frame (1). Steering frames (10) are installed on the lower portion of the machine frame (1), a cab (2) is arranged on the upper portion of the machine frame (1), an engine room (4) and a compressor chamber (6) are installed on the machine frame (1), a main conveying belt (5) is arranged on the machine frame (1), and a dirty soil conveying belt (3) is further connected to the main conveying belt (5). The tunnel track-bed ballast replacing machine is characterized in that the main conveying belt (5) is connected with a vacuum conveying device (7). According to the tunnel track-bed ballast replacing machine, stone ballast of a track bed inside a tunnel can be rapidly and efficiently replaced, and the tunnel track-bed ballast replacing machine is suitable for various tunnel railways such as standard-track railways, wide-track railways and narrow-track railways. When working, the tunnel track-bed ballast replacing machine meets the tunnel construction size requirement, releases manual labor, and is low in cost, long in service life and convenient to maintain, more precious time is gained for railway maintenance, and the work efficiency is improved. In addition, the tunnel track-bed ballast replacing machine is multiple in whole-machine work track distance type, high in efficiency and good in effect.

Description

technical field [0001] The invention relates to a ballast changing machine for a railway track bed, in particular to a ballast changing machine for a railway track bed in a tunnel. Background technique [0002] At present, there are no large and medium-sized models for the mechanized maintenance of line tunnels at home and abroad. The maintenance of domestic tunnel ballast is basically done manually, and due to the low efficiency and difficulty of manual maintenance, most of the domestic tunnel ballast has not been maintained for many years. . The biggest bottleneck in the mechanized maintenance of single-track tunnels is that there is only 200mm space between the two ends of the sleepers and the drainage ditch, which cannot be adapted by the existing cleaning machines. Manual screen cleaning in the tunnel has the disadvantages of poor working environment, low working efficiency and difficulty in guaranteeing the working quality.
