Guideway for trailers used for coal mining

Abstract

The invention discloses a trailer guide rail for coal mine development, which includes a guide rail body and a support assembly supported under the guide rail body, the support assembly includes a U-shaped base, and sleepers fixed in the base, and An insertion rod fixed in the base and passing through the base, a screw is fitted between the sleeper and the rail body, the insertion rod has an external thread, and the insertion rod is connected by the external thread There is a limit sleeve, the outside of the limit sleeve is provided with a limit plate, the limit plate is coaxially arranged with the limit sleeve, the lower end of the insertion rod is tapered, and the base and the sleeper The first screw is matched between them; in the actual use process, the device realizes the lower support of the guide rail body through the support component, improves the support stability, avoids the deformation of the guide rail body, and reduces the maintenance cost in the later period.

Description

technical field [0001] The invention relates to a trailer guide rail for coal mine development. Background technique [0002] In the process of coal mining, guide rails need to be laid in the mine tunnel. The guide rail can carry a trailer, and the mined coal mine is transported to the outside through the trailer. The mine tunnel guide rail in the prior art is simply fixed by sand and stone, so it is easy to occur. Bending deformation, resulting in higher maintenance costs. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is to provide a trailer guide rail for coal mining. In the actual use process, the device realizes the lower support of the guide rail body through the support assembly, improves the support stability, avoids the deformation of the guide rail body, and reduces the maintenance in the later stage. cost. [0004] In order to solve the above problems, the present invention adopts the following technical solutions...
