Lane cutting device and heading machine

Abstract

The invention relates to the technical field of lane heading and provides a lane cutting device and a heading machine. The lane cutting device comprises a linear transmission mechanism and a rocker arm. The first end of the rocker arm is connected to the linear transmission mechanism, moves along the linear transmission direction of the linear transmission mechanism and is hinged to the linear transmission mechanism, the second end is connected to a cutting head, and the cutting head rotates relative to the second end. Compared with existing cutting parts including cantilever type, roller typeand full section cutting parts, the lane cutting device comprising the linear transmission mechanism and the rocker arm can head various shape sections of the lane. The cutting part is smaller in occupied space and higher in cutting efficiency. The lane cutting device is better in adaptability for different cut sections, and the heading speed and the construction efficiency of the lane can be improved effectively.

Description

technical field [0001] The invention relates to the technical field of roadway excavation, in particular to a roadway cutting device and a roadheader. Background technique [0002] At present, my country's coal roadway excavation is facing problems such as slow speed of roadway formation, low level of mechanization and automation. The contradiction between mining at the working face and the speed of roadway forming leads to the tension of mining continuity and hinders the further improvement of coal scientific production capacity. [0003] Excavation equipment and technology are one of the key factors affecting the speed and efficiency of roadway excavation, among which the design of cutting part and construction technology are the main factors affecting the speed and efficiency of excavation. [0004] At present, there are three main designs of the cutting part of the coal roadway boring machine, namely the cantilever type, the drum type and the full-section type. The cor...

AI Technical Summary

Problems solved by technology

Due to the following problems in the coal mine test of the full-section roadheader: first, the weight of the whole machine is large, and it is difficult to adapt to the weak or steep floor conditions of the coal mine; second, there is usually a certain cutting blind area when cutting the full section; The resistance of full-section advancement is very large, and when encountering rocks, there are often situations where the advancement cannot be made; fourth, the direction control of the full-section cutting mechanism is difficult, and it is easy to cause deviations in the direction of excavation; fifth, when the section is cut, the front of the tunnel is closed, It is easy to cause carbon monoxide or gas to exceed the limit
