Description
Technical Field
The invention relates to the field of coal mine equipment, in particular to a track walking type foldable tunnel pipe-erecting machine for a coal mine.
Background
Along with the continuous deep research of four parts (lifting, transporting, mining and digging) of the traditional mining machinery, the level of mechanization, automation and intellectualization of lifting and transporting are increasingly improved, and unmanned and less comprehensive mining and comprehensive digging working surfaces are applied to partial mines. Under the background, the importance of the mine auxiliary mining system on the efficient and safe production of the coal mine is increasingly highlighted, but the auxiliary mining system is one of weak links and short plates of the safe and efficient production, the underground auxiliary frame pipe equipment is one of important components of the auxiliary mining system, the mine ventilation system, the drainage system and the like all need mine pipes, for how to install the mine pipes, except for enterprises with good partial roadway environments, the roadway mine pipes of most mining areas adopt a traditional installation mode, namely, the mine pipes are drilled on the inner walls, then the supports are inserted into the holes, workers use the hand-pulling blocks to lift the mine pipes in the complex environments of the coal mine, the installation is completed by continuously adjusting the positions of the pipes, and a plurality of workers are needed to cooperate with one another in the working process so as to complete the installation task.
The existing traditional installation mode has the following problems:
1) Difficult for the inner frame pipe of the narrow tunnel of the mine:
when the traditional method is adopted to install the pipeline, a worker uses the hand hoist to hoist the mining pipeline, on one hand, the worker is easy to collide with the pipeline in the installation position of the pipeline to cause accidental injury, and on the other hand, the worker needs to spend great effort in the whole construction process because of great mass of some pipelines, so that the problems of great labor intensity and low safety coefficient of the worker are caused.
2) Drilling difficulty in a narrow roadway of a mine:
In order to mount the support of the fixed pipeline in the mine, the support is required to be drilled at a certain height on the inner wall, a drilling machine is required to be used for completing the drilling, but under a complex roadway environment, the drilling of the drilling machine is very difficult to manually operate, the labor intensity of workers is increased, a great deal of dust and noise are generated in the drilling process, the physical and mental health of the workers can be greatly harmed, the mounting height of part of the mine pipeline can reach 2.2-3 m, the workers are easy to fall from high positions in the drilling process, the safety of the workers is threatened, and the traditional hydraulic drilling machine is difficult to meet the drilling requirement of the higher pipeline due to the limited working height.
3) The installation efficiency of the pipeline in the narrow roadway is low:
In the process of manually completing drilling, pipe hanging and fixing pipelines, the pipeline installation height can reach 2.2-3 m, the internal space is narrow, the environment is bad, and some pipelines are long and have large quality, so that the method for hanging and pulling the pipelines to the designated point is very time-consuming and labor-consuming, and the problem of low working efficiency is caused.
Therefore, it is necessary to develop a coal mine track walking type foldable tunnel pipe-supporting machine which is efficient, stable, safe, simple in control process and easy to move.
