Machine head auxiliary pushing device of scraper conveyor

Abstract

The invention provides a machine head auxiliary pushing device of a scraper conveyor. The device comprises a first telescopic mechanism, a second telescopic mechanism, a power integration mechanism, apushing telescopic rod, an auxiliary pushing mechanism and a hinge seat set. Compared with the prior art, the device has the following beneficial effects that hydraulic oil pipes are arranged, a hydraulic jack I and a hydraulic jack II of the auxiliary pushing mechanism can work normally and are connected with a control valve group through the hydraulic oil pipes, and the auxiliary pushing mechanism can be hinged to the upper surface of the right end of a supporting base through the hinge seat set due to the design of the auxiliary pushing mechanism and the hinge seat set. When the hydraulicjack I and the hydraulic jack II on the hinge seat set stretch and retract to work, supporting force is provided, the hydraulic jack I and the hydraulic jack II synchronously stretch when the pushingtelescopic rod pushes a machine head, the situation that the machine head frequently floats upwards in the pushing direction of a working face during use in the machine head operation process is avoided, the machine head is restrained from tilting, and normal pushing of the machine head is ensured.

Description

technical field [0001] The invention belongs to the field of auxiliary moving equipment, in particular to an auxiliary moving device for a machine head of a scraper conveyor. Background technique [0002] The conveyor that uses a scraper chain to transport bulk materials in the tank is called a scraper conveyor. KS Scraper Conveyor Scraper Conveyor The adjacent middle groove of the scraper conveyor can be bent to a limited extent in the horizontal and vertical planes, which is called a bendable scraper conveyor. Among them, the working face conveyor whose fuselage is bent at 90 degrees at the intersection of the working face and the transportation roadway is called "corner scraper conveyor". In the current coal mining face, the role of the scraper conveyor is not only to transport coal and materials, but also the running track of the coal mining machine, so it has become an indispensable main equipment in the modern coal mining process. The scraper conveyor can keep runnin...

AI Technical Summary

Problems solved by technology

[0003] However, during the mining process, when the head of the scraper conveyor is moved in front of the work, the height of the bottom plate of the front scraper conveyor head is not enough after cutting by the coal mining team, and the scraper head is easily caused when the head of the scraper machine is moved. The head of the machine often floats upward along the advancing direction of the working surface during use, causing the head to tilt and affecting the movement of the machine head
