Example Embodiment

[0030] The specific embodiments of the present invention will be further described below with reference to the drawings and technical solutions.

[0031] The traditional full-face rock boring machine uses the overall rotation of the cutter head to make the hob continuously squeeze the rock. When the stress exerted by the hob on the rock is greater than the limit stress of the rock, the rock will crack and break. To achieve the effect of breaking the rock. In this process, the hob is in direct contact with the rock, and the vibration generated by rock breaking will be transmitted to the entire cutter head through the hob. The resulting vibration is huge, which seriously affects the stability and reliability of the roadheader. Sex.

[0032] The invention uses a laser and a high-pressure water gun to break the rock, so that most of the working time of the roadheader is not in direct contact with the rock surface, thus effectively reducing the vibration of the cutter head, improving t...

Abstract

The invention belongs to the technical field of tunnelling of full fracture surface rock tunnelling machines and provides a design method for a cutter head of a laser full fracture surface rock tunnelling machine. A combination of a laser and a high-pressure water jet is adopted to break rock, the rock breaking mode of the cutter head is not dependent on the rolling effect of a hob and rock, therefore, a center plate on a traditional cutter head is removed, a laser device and a high-pressure water gun are driven by different shafts correspondingly, after the rock is treated by the laser, the rock surface is immediately sprayed through the high-pressure water gun, and then the remaining rock is treated through an edge scraper, so that the purpose of rock breaking is achieved. The cutter head does not make contact with the rock surface for most of the time, so that compared with the traditional cutter head, the vibration amplitude of the cutter head can be greatly reduced; molten slag and rock slag can be effectively removed and the high temperature caused by the laser can be reduced due to the existence of a high-pressure water flow; and the cutter head is not provided with the center plate, so that the water flow entrained waste slag can be conveniently discharged out of a working area.

Description

technical field [0001] The invention belongs to the technical field of full-section rock excavation machines. On the basis of existing traditional full-section hard rock excavation machine cutter heads, a full-section rock-breaking excavator cutter head structure combining laser and high-pressure water jets is designed. Background technique [0002] In recent years, full-face rock boring machines have been widely used in the construction of water conservancy projects, railway transportation, subway projects, oil and gas pipelines and national defense tunnels in China. But most of these projects use traditional tunneling methods, which use rotating disc-shaped cutterheads and pressure on the blade face to cut through the rock. Although compared with the original drill and blast method, the TBM tunneling device overcomes the shortcomings of its low degree of mechanization, low labor productivity, low equipment utilization and low safety. However, due to the harsh working envi...
