Excavating and supporting integrating method and carrying type lifting and transporting support manipulator for heading machine

Abstract

The invention specifically discloses an excavating and supporting integrating method and a carrying type lifting and transporting support manipulator for a heading machine. The manipulator structurally comprises a supporting frame which is provided with a guide rail; a support carrying trolley is arranged on the guide rail, can slide along the guide rail back and forth and can move back and forth forwards and backwards under the action of a drive device; a mobile beam is arranged at the front of the support carrying trolley and is driven by the drive device to move forwards and backwards. In this way, remote-control excavating and supporting integration can be achieved if the automatic heading machine is adopted, electro-hydraulic control valves are arranged on jacks on the device, and visualized monitoring is added.

Description

[0001] technical field [0002] The invention relates to a mechanized operation process and equipment for safe, efficient and rapid construction of an underground project, and in particular to an integrated excavation process of excavation and support and a supporting manipulator of the excavation machine for lifting and moving supports. Background technique [0003] The comprehensive mechanized excavation construction technology of underground engineering has been widely promoted and applied because of its safety and reliability, and its single-entry efficiency is much higher than the traditional blasting excavation technology. The main time-consuming of one cycle of comprehensive mechanized tunneling construction technology is cutting by roadheader and roadway support. How to realize the parallel operation of roadheader cutting and roadway support, since the 1950s, domestic and foreign mining circles have carried out a lot of exploration, and produced a lot of technology a...

Problems solved by technology

[0014] 2. The joist-type temporary support of the roadheader frame, the net laying operation is still under the empty roof, the support area cannot reach the full section, the strength of the frame and the connection strength with the roadheader are limited, and the support force is very small. Under temporary support and permanent support, the roadheader cannot work in parallel

Since the birth of the first-generation bolter in the 1960s, two changes have been made. The third generation of bolt-digging is integrated. Although the parallel operation of bolt-digging has been realized, the empty head distance of the bolt is large, generally more than 1.2-1.5 meters. , the support cannot keep up with the head, so it is only suitable for large-section rectangular or trapezoidal roadways with small mining depth, small mine pressure and good surrounding rock conditions. Therefore, it has not been widely promoted and applied.

For example, most of the mining areas in my country and Germany, Poland and other countries have deep mining depth, high mine pressure, soft and broken surrounding rocks, dense anchor rods, and even need hanging nets and anchor cables for support, and the support workload is heavy. Not only the empty top distance cannot meet the requirements, the support time is much longer than the cutting time, and it is difficult to synchronize with the cutting

[0016] 4. Front and rear push-pull or paired alternate stepping hydraulic self-moving support supports the roof repeatedly once in each cycle, which is easy to damage the roof and is not conducive to the support of the roof. When the condition of the roof is not good, it must be stopped for support, which cannot be realized Parallel operation of roadheader cutting and permanent support

This support method supports the head-to-head support of the roof through the entire length of the shield to the surrounding rock, shrinks, moves forward, and supports again. Repeated support is easy to damage the surrounding rock. It is only suitable for large bend radius and large sections. 1. Tunnel construction with better surrounding rock conditions is easy to get stuck when encountering faults and broken zones
