Tunneling, anchoring and supporting integrated machine

Abstract

The invention relates to a tunneling, anchoring and supporting integrated machine, which comprises a tunneling device, and is characterized in that the tunneling device is hinged with a body, wherein the tunneling device is provided with an anchoring and supporting device; the specific structure is that the anchoring and supporting device comprises a frame, a top telescopic supporting device, a bottom telescopic supporting device, a left telescopic component, a right telescopic component and an onboard bolting machine; one end of the left telescopic component and one end of the right telescopic component are fixedly arranged on the frame; the other ends of the left telescopic component and the right telescopic component are hinged with the onboard bolting machine respectively; the onboard bolting machine is positioned and rotated around a hinge point; one end of the top telescopic supporting device and one end of the bottom telescopic supporting device are fixedly connected to the frame; hydraulic guide devices are arranged on the two sides of the tunneling device; and one end of each of the hydraulic guide devices is fixedly connected with the rear part of the tunneling device, and the other end of each of the hydraulic guide devices is hinged with the frame of the anchoring and supporting device.

Description

technical field [0001] The invention relates to an integrated machine for excavating, anchoring and protecting, which is a multi-functional excavating equipment integrating excavation, bolting and temporary support, especially an integrated roadheader which can be folded for bolting and temporary support. In mines, coal mines and tunneling projects. Background technique [0002] With the rapid development of my country's economy, the coal industry is constantly developing towards mechanization and automation. Comprehensive mechanization equipment is more and more widely used in coal production under various geological conditions. [0003] In the roadway excavation process, except for the improvement of the quality of the roadheader itself, the overall technological level still maintains the level of the 1970s and 1980s. The main reason is that limited by geological conditions, the empty head distance is small, and the parallel operation of excavation and support work cannot...

AI Technical Summary

Problems solved by technology

[0005] The bolter of the two-sided bolter is installed on both sides of the cutting part. When the roadheader is working, the tunneling device is easy to scrape the side and be damaged when it swings left and right; when the bolter is working, it cannot reach the front end of the equipment. Have a certain empty head distance

[0006] The position of the anchor protection device of the gantry-type anchor digger and protection integrated machine is on the body of the roadheader. It cannot be folded during use, and there are problems such as blocking the line of sight of the cutting part. Because the two telescopic main arms are too long and the rigidity is poor, the front end The anchor protection device is completely cantilever structure. When the main arm is extended and retracted, the anchor protection device trembles seriously. Because the main arm is too long, the hydraulic pipe is too long, so it is difficult for the two main arms to keep in sync. The hydraulic oil pipe and electrical wiring are too long due to the main arm. also difficult to arrange
