Description

Technical Field

[0002] Roadheaders are widely used in tunnel excavation operations. Roadheaders can be used for excavation in flat and inclined tunnels, but in thin coal seams with a long service life and many faults, due to the large inclination angle, the roadheader has difficulty in crawling or even sliding during excavation, which limits the application of the roadheader. In addition, tunnel excavation operations are more difficult and require auxiliary operations with booster devices to facilitate the convenient processing of the device.

[0003] Among the existing technical solutions, a thrust mechanism for a tunnel boring machine used for climbing a slope in a tunnel is proposed, with publication number: CN201671628U. The mechanism includes a connecting frame, an adjustment device, a crossbeam, a support leg and a cylinder. The adjustment device is arranged between the connecting frame and the crossbeam. The support leg and the cylinder have two groups symmetrically arranged at both ends of the crossbeam. The cylinder is fixed on the crossbeam, and the end of the cylinder rod is fixedly connected to the end of the support leg, and the support leg is movably connected to the crossbeam.

[0004] In order to solve the problem that the tunnel boring machine at a large angle will slide down, cannot dig normally, the working environment is subject to certain restrictions, and the normal work progress is affected, the existing technology uses an adjustment device arranged between the connecting frame and the beam, and two groups of support legs and cylinders are symmetrically arranged at both ends of the beam. The cylinder is fixed on the beam, and the end of the cylinder rod is fixedly connected to the end of the support leg, and the support leg is movably connected to the beam. It is easy to use, and it can enable the tunnel boring machine to work normally when the tunnel angle is greater than or equal to 18° and less than 24°, and it is handled in a manner not restricted by the environment. However, there is still a problem that the disassembly mechanism of the booster device is poor, which is not conducive to the convenient disassembly and maintenance of the device.
