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

[0029]In the present invention, the subsidiary transport system fully uses a space between the advanced support system and the anchoring robot system in the equipment and adopts a chain wheel and chain transporting mode, so that a size of a subsidiary transporting device is reduced, types and amounts of materials to be carried are increased, and the volume of the whole set of equipment is smaller. The present invention is especially suitable for being used in a narrow tunnel at “Huainan and Huaibei basins”.

[0030]2) The driving system in the present invention adopts a structure of gear, rack and differential mechanism, and the maneuvering characteristics of the equipment are good.

[0031]In the present invention, racks are welded at both sides of a lower end of the rail, and a motor drives a reducer engaged with the rack to rotate, so as to enable the equipment to have good slope changing performance. Meanwhile, a differential mechanism is mounted inside the reducer, so that advancing speeds at an inner side and an outer side of the equipment are different in a turning process, thus realizing the turning of a relatively small radian. Therefore, the present invention has good maneuvering characteristics, and can stably advance in a hostile tunnel environment.

[0032]3) The anchoring robot working platform in the present invention has a buffering function and an anchoring process is stable.

[0033]In the present invention, the driving between the anchoring robot at an upper end of the anchoring robot working platform and the platform is realized by electromagnetism, so that the movement and control accuracy is higher, which is conducive to accurate positioning and drilling of the jumbolter; and a lower end of the platform is connected with the hydraulic system. When the jumbolter is in operation, a bottom end of the hydraulic system is supported by the ground, so as to absorb an impact force generated in a drilling process and transmit the impact force to the ground, thus making the platform more stable, and providing a good working condition for the jumbolter.

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.
