Description

technical field [0001] The invention relates to the field of coal mine equipment, in particular to a mechanical arm type pipe erecting machine for fully mechanized excavation in coal mines. Background technique [0002] With the continuous deepening of research on the four major parts of traditional mining machinery (lifting, transporting, mining, and digging), the integration, mechanization, and intelligence of lifting, transporting, mining, and digging have been increasingly improved, and unmanned and less-manned fully mechanized mining And comprehensive excavation work has been applied in some mines. In this context, the importance of the mine auxiliary mining equipment system to the efficient and safe production of coal mines has become increasingly prominent, and the auxiliary pipe erection equipment used in coal mines is the short board and weak link in the efficient production of the mining system, but the ventilation system and drainage system in coal mines The syst...

AI Technical Summary

Problems solved by technology

[0004] 1) The pipe erection equipment has a single function and the pipe installation steps are discontinuous

[0005] The pipe erecting device commonly used in general enterprises now has a single structure, and the pipe erecting device can only simply complete the height increase of the pipe, and the subsequent drilling work and installation work require the assistance of other equipment and personnel, resulting in pipe erection. The entire pipe erection process cannot be completed directly and continuously. Due to the continuous need for personnel and other equipment to join in the pipe erection work, the problem of discontinuous pipeline installation steps is more obvious

[0006] 2) The functional integration of pipe erection equipment is not high, and the efficiency of pipe erection is not high

[0007] Except for some enterprises with good roadway environment, the roadway mining pipelines in most mining areas still adopt the traditional installation method, that is, drill holes on the inner wall, then insert the brackets into the holes, and then workers use chain hoists to lift in the complex environment of the coal mine. Mining pipelines are installed by constantly adjusting the pipeline position. This work process requires multiple workers to cooperate with each other to complete the installation task. During the process of manually completing drilling, hanging pipes, and fixing pipelines, the installation height of the pipeline can reach 2.2-3m. The space is narrow, the environment is harsh, and some pipelines are not only very long but also of high quality. It is very time-consuming and labor-intensive to use this method of hoisting to the designated point, resulting in low work efficiency.

[0008] 3) The tube erecting equipment lacks positioning and adjustment functions, and the automation of the tube erecting equipment is low

The method of hoisting to the designated point is still widely used. This method not only increases the labor intensity of the workers, but also causes great harm to the physical and mental health of the workers due to the noise generated during the installation process. Since the hanging pipes are mostly done manually, Therefore, the adjustment process of the fixed pipe is extremely difficult, and several workers are required to complete the adjustment continuously. The existing pipe erection equipment simply lifts the pipe and then turns the hole on the wall. There is no automation, and after the pipe is raised to the height, the position difficult to adjust
