Monorail anchoring and supporting cooperative machine for fully mechanized excavation face

Abstract

The present invention discloses electromechanical equipment integrating functions of anchor protection and supporting, including a suspension support system, a power system, an advanced support system, a subsidiary transport system and an anchoring robot system. The suspension support system is fixed on a top end of a coal mining tunnel through an anchor rod to provide support for the system. The power system is mounted at a tail end of a system main beam in the suspension support system. The advanced support system is mounted at a front end of the system main beam in the suspension support system. The subsidiary transport system is mounted on the system main beam in the suspension support system at a rear side of the advanced support system. The anchoring robot system is mounted on the system main beam in the suspension support system between the power system and the subsidiary transport system. Furthermore, the present invention has good turning and slope changing performance, and the transport efficiency of the equipment is high. In addition, an anchoring robot working platform has a buffering function, the anchoring is stable, and the operation efficiency is high.

Description

BACKGROUNDTechnical Field[0001]The present invention relates to the field of electromechanical equipment for fully mechanized excavation faces, particularly to electromechanical equipment integrating the functions of anchor protection and supporting, and belongs to the scope of anchoring and supporting integrated machines.Related Art[0002]In recent years, the research and development of coal mining technologies and equipment in China have made significant breakthroughs, and coal mining operation has proposed higher requirements on mining speed while requiring less people or no people. In order to solve the problem of “mining maladjustment” in a coal mining process, a great deal of manpower and material resources has been invested in the research and development of road-headers, and great progress has been made. At present, the main factors that restrict the further improvement of production capacity of fully-mechanized coal mining are low anchoring and supporting operating speed and...

AI Technical Summary

Benefits of technology

The objective of this patent is to provide a new technology for anchor protection and supporting in coal mining tunnels that reduces the size of equipment and improves its maneuverability. The aim is to achieve efficient and effective anchor protection and ultimately create a fully mechanized excavation face.

Problems solved by technology

At present, the main factors that restrict the further improvement of production capacity of fully-mechanized coal mining are low anchoring and supporting operating speed and low work efficiency.

Although such all-in-one machines have the function of multi-process operation, the processes cannot be performed simultaneously, so that the problem of cooperative operation of tunneling, anchoring and supporting is not fundamentally solved.

1) The size of the equipment is large, and the usable range is limited.

In the patent, an anchoring device, a supporting device and the road-header are separated, so that the overall equipment size is greatly reduced compared with a conventional tunneling-anchoring-supporting integrated machine, is suitable for tunnels of common mines, but the structure of a subsidiary carrying mechanism is relatively complicated and heavy, which is not conducive to the transport of the equipment, and the application range is limited to a certain extent.

2) Turning maneuvering characteristics of the equipment is poor and is not conductive to transport.

The requirement on performance of the power system on the monorail crane is very high especially when the tunnel has a bending or a slope, but the power system is only that a motor drives a power buggy through a reducer, and the turning performance and anti-slipping performance of the whole set of equipment in a running process on the rail are relatively poor.

3) An anchoring platform of the equipment is unstable and is not conducive to the anchoring operation.

A jumbolter may generate a great impact force in a drilling process, which is directly acted on the working platform; however, the platform has no buffering function, so that the anchoring robot working platform cannot provide a stable working environment for the jumbolter, which is not conducive to the anchoring operation.
