Problems solved by technology

[0004] The purpose of the present invention is to provide a kind of heavy-duty hard rock roadheader, solves that existing roadheader is not suitable for large section (20M 2 Above) semi-rock roadway and high-hardness (f8) whole-rock tunneling, when cutting hard rock, the machine vibrates greatly, there is a lot of dust, and the machine slides sideways. Greatly reduce the operator's work intensity, improve the operator's working environment, and improve reliability

Abstract

The invention relates to the coal mine roadway drivage machinery, in particular to a heavy hard rock tunneling machine which can cut a semi-rock roadway and a whole-rock roadway with high hardness. The tunneling machine solves the problem that the prior mole is not suitable for rock roadway drivage, can greatly improve the drivage working efficiency of the whole-rock roadway, and dramatically reduce working intensity of operators. The tunneling machine has an integral structure with high strength, a complete machine with heavy weight, a horizontal side support arranged on the back of the machine, and a device with high stability; the machine is provided with a mighty dust absorption system and an inside and outside spray dust suppression system, which effectively improves working environment of the operators; a traction of the tunneling machine adopts a full-sealed structure to increase traction driving force and improve propulsive force of the cutting; the tunneling machine has a small assembly, a large diameter and an inertia cutting head, adopts a reliable and highly-efficient hydraulic system matched with a high-strength point-attack pick, which greatly improves unidentate cutting force, thereby the tunneling machine has the ability of cutting the semi-rock roadway and the whole-rock roadway with high-hardness (f8).

Description

technical field [0001] The invention relates to coal mine roadway tunneling machinery, in particular to a hard rock tunneling machine, which can realize the tunneling operation of large-section semi-rock roadway or high-hardness (f8) whole rock. Background technique [0002] Currently, large sections (20M 2 The excavation of half-rock roadway and whole rock above) adopts blasting operation, which is a difficult and dangerous work. The production efficiency of blasting operation is low, and the labor intensity of the operator is high. After the blasting operation, the rock structure around the roadway will be affected The strength caused some damage. And existing tunneling equipment is mainly applicable to coal rock and semi-coal rock roadway of medium hardness, is not suitable for whole rock roadway operation; The service life of the interior spraying system that adopts is very short, and it is difficult to replace and maintain after being damaged; Without effective contro...
