Scraper conveyor pushing structure for pitching oblique mining way of fully-mechanized coal mining face of sharp-inclined coal seam

Abstract

The invention discloses a scraper conveyor pushing structure for a pitching oblique mining way of a fully-mechanized coal mining face of a sharp-inclined coal seam. The scraper conveyor pushing structure for the pitching oblique mining way of the fully-mechanized coal mining face of the sharp-inclined coal seam comprises a coal cutter arranged in the fully-mechanized coal mining face, a plurality of sections of guiding chutes which are connected in sequence, a plurality of hydraulic supports constituting a support system, and an electrohydraulic control system mounted on the hydraulic supports. Pushing oil cylinders and pushing rods are arranged in a base. An anti-slip oil cylinder is further arranged at the front end of the base. Cable-stayed oil cylinders are further arranged on the hydraulic supports. The electrohydraulic control system achieves automatic control over the scraper conveyor pushing process by the hydraulic supports through a control program. The scraper conveyor pushing structure has the advantages of being capable of achieving automatic control, simple in structure, high in precision, safe, reliable, convenient to mount, maintain and use and the like, and is worthy of popularization in the industry.

Description

technical field [0001] The invention belongs to the technical field of coal mining machinery, and in particular relates to a push-sliding structure used in a fully mechanized coal mining face with steeply inclined coal seams in a downward pseudo-inclined mining mode. Background technique [0002] Coal seam comprehensive mechanized mining has the characteristics of high safety, low labor intensity and high production efficiency. The existing comprehensive mechanized mining technology has also been applied in 45°-85° steeply inclined coal seams, and has achieved good social benefits. [0003] In the fully mechanized mining face with an inclination, as the scraper conveyor is moving, it will generate a downward sliding force, causing the scraper conveyor (commonly known as the slipper) to slide down as a whole. In order to realize the normal operation of the working face, the scraper conveyor and hydraulic support of the working face should maintain the running posture, that i...

AI Technical Summary

Problems solved by technology

[0004] At present, manual valves or group pushing methods are basically used for pushing, which has poor efficiency, high labor intensity and high risk, and most of them are mined in the way of true inclination or false inclination, and the design of push rods mostly adopts one-way lock.
