Mine Shaft Chainsaw Hard Rock Tunneling Machine

Abstract

The invention discloses a mining laneway chain saw type hard rock roadheader. The mining laneway chain saw type hard rock roadheader comprises a body, a hydraulic device, a lifting oil cylinder, a rotary oil cylinder and a conveying belt, wherein the hydraulic device is arranged on the body and is provided with a hydraulic chain saw and a hydraulic crushing head which are connected with a hydraulic pipeline of the hydraulic device and has the action of cutting or crushing respectively; the lifting oil cylinder and the rotary oil cylinder are connected with the hydraulic pipeline of the hydraulic device, piston rods of the lifting oil cylinder and the rotary oil cylinder are connected with the back ends of the hydraulic chain saw and the hydraulic crushing head respectively and drive the hydraulic chain saw and the hydraulic crushing head to move up and down or from left to right respectively; the conveying belt transports rocks generated by tunneling backwards. Due to the adoption of the mining laneway chain saw type hard rock roadheader, the tunneling problem of hard rocks or superhard rocks is solved by virtue of a mechanized mode, the blasting procedure is saved, and the mining laneway chain saw type hard rock roadheader is safe, is high in efficiency and is not restrained by use administrative provisions of initiating explosive products; a laneway is good in formation, the destruction to surrounding rock is small, the support can be simplified or not needed, the operation time and the engineering cost are saved, the construction progress is accelerated, and the tunneling cost is lowered.

Description

technical field [0001] The invention relates to a tunneling device for a mine shaft, in particular to a chainsaw type tunneling machine used for a superhard rock shaft. Background technique [0002] Coal mines and other mine shafts all need to adopt the tunneling method to excavate the shaft to meet the requirements of mining construction; the existing technology tunneling methods generally use drilling blasting or roadheader tunneling, and drilling blasting is to drill and blast in the area that needs to be tunneled. The blast hole used is filled with explosives, and the shock wave and force generated by detonating the explosive will loosen or crack the rocks and soil in the excavation area, so as to facilitate the excavation construction. [0003] Present various roadheaders all rely on the cutting head of the roadheader to rotate and cut rocks with picks to realize rock-breaking tunneling. However, because the underground space limits the infinite increase of the volume ...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the purpose of the present invention is to solve the problem that the existing roadheader is only suitable for rocks below medium hardness. If it is used for hard rock or superhard rock, there will be large damage to the picks, short service life of the picks, and difficulty in driving. With the defects of low construction efficiency and significantly increased construction cost, a chainsaw type hard rock roadheader suitable for hard rock or super hard rock tunneling construction is provided.
