Hard Rock Tunneling Machine

Abstract

The invention relates to a hard rock roadheader, which includes a chassis traveling mechanism and a body provided with a cab and a power system, and is characterized in that it also includes a drilling splitting mechanism, an excavating mechanism, a shovel bucket and a conveying mechanism. The splitting mechanism is set at the front upper part of the machine body, the excavating mechanism is set at the front middle part of the machine body, the shovel bucket is set at the front lower part of the machine body, the conveying mechanism is set in the chassis running mechanism, the front end of the conveying mechanism is set at the rear end of the shovel hopper, and the conveying mechanism is set at the rear The end extends to the rear of the body. The invention does not need explosive blasting during excavation, and has high excavation efficiency and good safety.

Description

technical field [0001] The invention relates to the technical field of tunnel and roadway excavation machinery, in particular to a hard rock excavation machine capable of realizing high-hardness whole-rock excavation operations with various shapes and large sections. Background technique [0002] At present, in the process of coal mining or engineering construction, the construction of tunnels and roadways is often carried out. In the construction of tunnels and roadways, when hard rock is encountered, the operation process is mainly: advanced drilling-measurement and setting-out-trolley Drilling (or artificial drilling)——charging and blasting—dust removal—ballasting—ballasting. During the construction process, drilling and charging will take a lot of time. When blasting, it is necessary to transfer all After the blasting, several hours of dust removal and risk removal are needed, and then the machinery and personnel are loaded and transported for ballast cleaning. After cle...

Problems solved by technology

It can be seen that the construction efficiency is low, and because the drilling and blasting method is used for excavation construction, safety accidents are prone to occur when the rock formation is unstable and adjacent to urban areas and residential areas.

[0003] Chinese patent application No. 200710012409.5 discloses a hard rock roadheader. Although the hard rock roadheader improves work efficiency, it can only dig rocks with a hardness below f8, and its scope of application is narrow; the patent application No. 201110234799.7 is Another kind of hard rock roadheader is disclosed, which is drilled by the drilling machine on the first installation frame, and then splits the rock with the rock splitter on the second installation frame. Second, when the rock splitter is inserted into the rock hole by the mounting frame, it is difficult to ensure that the splitting rod and the hole are completely coincident, and the splitting rod is easily damaged if the angle is slightly deviated, so the practicability is not high
