Roadway tunneling support robot, matching support and support method

Abstract

The invention discloses a roadway excavation support robot suitable for coal mine roadway and tunnel construction technology, a matching multi-directional adjustable excavation support, and a conveyor for transporting multi-direction adjustable excavation supports, and proposes a support method at the same time; The excavation support robot is composed of the second transport underframe, walking frame, lifting platform, drilling and anchor manipulator, automatic positioning device, hydraulic pump station and hydraulic operating system; the adjustable support consists of beams, supporting leg cylinders, supporting cylinders, It consists of side beams and support frames; the conveyor is composed of a track with sleeve rollers or sleeve roller chains and a transport trolley running on the track; when working, the roadway excavation support robot is hinged with the tailstock of the roadheader, and then The tunnel boring machine moves together, and under the cover of the multi-directional adjustable tunneling support, bolt support is carried out on the top and two sides of the tunnel while tunneling, so as to achieve the purpose of parallel operation and double the operating rate of the tunnel boring machine, thereby improving Drilling speed.

Description

technical field [0001] The invention relates to roadway and tunnel support technology. Background technique [0002] In recent years, although roadway boring machines have been widely used, the speed of tunneling still cannot meet the needs of coal mining; the main reason is that the problem of parallel operation between the main process of tunneling and auxiliary processes such as support cannot be solved, that is, no support, support, etc. No excavation during protection will affect the construction speed. At present, although the application of technologies such as the integrated machine for digging and bolting has improved the speed of excavation and the degree of mechanization and reduced some labor intensity, it still cannot meet the requirements for excavation speed due to the inability to work in parallel. [0003] Although the surface tunneling operation equipment is also very advanced at present, due to the particularity of the coal mine roadway excavation operati...

Problems solved by technology

[0002] In recent years, although roadway boring machines have been widely used, the speed of tunneling still cannot meet the needs of coal mining; the main reason is that the problem of parallel operation between the main process of tunneling and auxiliary processes such as support cannot be solved, that is, no support, support, etc. No excavation during maintenance will affect the construction speed

At present, although the application of technologies such as the integrated machine for digging and bolting has improved the excavation speed and the degree of mechanization and reduced part of the labor intensity, it cannot meet the requirements for excavation speed due to the inability to work in parallel.

[0003] Although the surface tunneling operation equipment is also very advanced at present, due to the particularity of the coal mine roadway excavation operation environment, the application of the coal mine roadway excavation operation equipment and the surface tunnel excavation operation equipment is very different. It has become an urgent problem to be solved to develop a roadway excavation support robot with compact structure, stable performance and real application.

[0004] Furthermore, after the current roadway boring machine is excavated, it cannot temporarily support the roof in time, and cannot effectively control the state of the surrounding rock after excavation. After the roof is empty, the cracks will expand. Most of them are supported by temporary brackets, but the current temporary brackets cannot be arched, tightly pressed, or jacked up, and cannot effectively control the state of surrounding rock after excavation, and the roof will still be deformed after bolting
