The invention discloses an overhand mining working face end device universal auxiliary advancing device and method. The device mainly comprises structures of an external poured advancing jack, auxiliary advancing support seats, a small-sized external poured jack, pin bodies, a subplate and the like. The method comprises the following steps that the auxiliary advancing support seats are arranged, and the bottom of a cylinder body of the external poured advancing jack is connected with the auxiliary advancing support seats through the pin body; an operating valve group is controlled to feed liquid according to specific requirements, the small-sized external poured jack is adjusted, and a piston end of the external poured advancing jack is fixedly connected with the corresponding auxiliary advancing support seat on a shell of a hydraulic coupler through the pin body; a hydraulic support frame operating valve group is controlled to feed liquid to the external poured advancing jack according to requirements of different dynamic loading to assist an advancing scraper conveyor head; and the hydraulic support frame control valve group is controlled to enable a piston rod to pull a hydraulic support frame using the pin body on the shell of the hydraulic coupler as a fulcrum under the action of high-pressure emulsion to complete a work cycle. The overhand mining working face end device universal auxiliary advancing device and method are of great significance for improving the production efficiency of the working face.
Description
technical field [0001] The invention relates to an external injection type pushing jack, in particular to a method for universally assisting pushing the head, tail and hydraulic support of a scraper conveyor on an upward mining working face. Background technique [0002] As the main supporting equipment of the fully mechanized mining face, the scraper conveyor is not only responsible for the task of coal transportation, but also the running track of the coal mining machine and the fulcrum of the hydraulic support; the hydraulic support is an important equipment for supporting the roof of the working face, protecting Safety of equipment and personnel. Therefore, the reliable, stable and efficient operation of scraper conveyors and hydraulic supports will directly affect the production capacity of mines and the economic benefits of coal mining enterprises. [0003] When the working face is tilted upwards or the turning direction is large, there is a large amount of floating c...
