Description
Technical Field
The invention relates to the field of coal mine equipment, in particular to a mechanical arm type pipe erecting machine for fully mechanized excavation of a coal mine.
Background
With the continuous deepening of the research on four major parts (lifting, transporting, mining and digging) of the traditional mining machinery, the level of integration, mechanization and intellectualization of lifting, transporting, mining and digging is increasingly improved, and unmanned and less-humanized fully-mechanized mining and fully-mechanized digging work is applied to part of mines. Under the background, the importance of the auxiliary mining equipment system for the efficient and safe production of the coal mine is increasingly highlighted, the auxiliary frame pipe equipment used in the coal mine is a short plate and a weak link for the efficient production of the mining system, but pipelines are required to be installed in a ventilation system, a drainage system and the like in the coal mine, and therefore the installation amount of the pipelines is extremely large. For the existing pipeline installation equipment, most pipeline installation equipment has single function, the continuity of pipeline installation work is poor, and the pipeline installation efficiency is low, for example, a rail walking type foldable roadway pipe erecting machine for coal mines (granted publication number: N209817930U), although the equipment solves the problem that the height of a pipeline needs to be manually lifted, pipeline installation personnel still need to manually climb to the height of the pipe erecting machine to complete installation, the working process needs a plurality of workers to cooperate with each other to complete the installation task, and a protection device for high-altitude pipeline installation personnel is lacked in a severe underground environment, besides, the problem that the continuity of the pipeline installation step is not strong still needs to be solved.
The existing installation equipment has the following problems:
1) the pipe erecting equipment has single function and discontinuous pipeline installation steps.
Present general enterprise commonly used frame pipe device, its single structure, frame pipe device can only simply accomplish the high promotion of pipeline, later change hole work and installation work need other equipment and personnel's assistance again to lead to when putting up the pipe, can not direct continuous whole frame pipe course of work of completion, owing to when putting up the pipe work and going on, constantly need the joining of personnel and other equipment, lead to the discontinuous problem of pipeline installation step more obvious.
2) The functional integration degree of the pipe erecting equipment is not high, and the pipe erecting efficiency is not high.
Except for enterprises with good partial roadway environment, the roadway mining pipelines in most mining areas still adopt the traditional installation mode, namely, holes are drilled on the inner wall, then the bracket is inserted into the holes, then workers use the chain block to lift the mining pipelines under the complex environment of a coal mine, the pipeline position is continuously adjusted to complete installation, the installation task can be completed only by mutual cooperation of a plurality of workers in the working process, in the process of manually completing the drilling, pipe hanging and pipeline fixing, because the pipeline installation height can reach 2.2-3 m, the internal space is narrow and small, the environment is severe, and some pipelines are not only very long but also very large in quality, the method for lifting and pulling the pipelines to the appointed points is very time-consuming and labor-consuming, and the problem of low working efficiency is caused.
3) The pipe erecting equipment lacks a positioning and adjusting function, and the automation degree of the pipe erecting equipment is low.
At present, most of pipe erecting equipment used in mining areas is used as auxiliary equipment for installing pipelines, a main body of installation work is still pipeline installation personnel, and the pipe erecting equipment is only an auxiliary tool of workers. The method of hoisting and pulling to the appointed point is still widely used at present, the method not only increases the labor intensity of workers, but also causes great harm to the physical and mental health of the workers due to the noise generated in the installation process, as the hoisting pipes are mostly manually completed, the pipe fixing and adjusting process is extremely difficult, a plurality of workers are required to perform continuous adjustment, the existing pipe erecting equipment is only used for simply lifting the pipe and then drilling on the wall, the automation is not displayed, and the position adjustment is difficult after the pipe is lifted to the height.
Therefore, there is a need to develop a mechanical arm type pipe erecting machine for fully mechanized coal mining, which has complete functions, high pipe erecting efficiency, high automation degree and easy adjustment and positioning.

The working principle of the pipe erecting machine is as follows:
a mechanical arm type pipe erecting machine for coal mine comprehensive digging is started to work in a state that a first knuckle arm 53 and a second knuckle arm 54 are folded, and a lifting mechanism 84 is also folded.
Firstly, a pipe clamping and lifting process: the pipe erecting machine is pulled to a specified working position by a tractor, the mechanical arm part can be rotated to one side needing to clamp a pipeline by the movement of the large gear rack hydraulic cylinder 3, then the small gear rack hydraulic cylinder 52 and the cycloid motor 56 move cooperatively to enable the clamping mechanism 65 to reach the pipeline position, the paw opening and closing hydraulic cylinder 62 shortens to clamp the pipeline, and then the small gear rack hydraulic cylinder 52 and the cycloid motor 56 move cooperatively to lift the height of the clamping mechanism 65 to a required height.
Adjusting, drilling and pipe erecting processes: after the height of the clamping mechanism 65 is lifted to a required height, the front and rear sliding blocks 28 slide in the front and rear sliding ways 27 to drive the sliding block sliding way connecting plates 21 fixed with the front and rear sliding ways, and similarly, the left and right sliding blocks 23 slide in the left and right sliding ways 22 to drive the connecting plates 26 fixed with the front and rear sliding ways, so that the pipe erecting machine can quickly and accurately adjust the pipeline to a specified installation position, then the drilling mechanism starts drilling, the motor box 611 slides in the sliding cavity 610 to drill the rotating rod 612, after the drilling is finished, the drilling mechanism returns to the initial position, then the lifting mechanism 84 lifts workers to the working height, and the pipe erecting work continues.
Thirdly, the process of pipe erecting is finished: after the pipe erecting operation is completed, the lifting mechanism 84 is first returned to the initial position, and then the first knuckle arm 53 and the second knuckle arm 54 are also returned to the initial position, and the pipe erecting machine is pulled by the tractor to the next pipe erecting position, and the above operation is repeated.
