Impact type hydraulic jumbolter, control method and application

Abstract

The invention belongs to the technical field of anchor rod supporting equipment, and discloses an impact type hydraulic jumbolter, a control method and application. A positioning oil cylinder is installed below a bottom plate assembly, and the front end of the positioning oil cylinder is connected with a clamp holder. A second oil cylinder is installed on the right side of the bottom plate assembly, a slideway frame is arranged on the bottom plate assembly, and a clamping device is installed at the front end of the slideway frame. A first oil cylinder is mounted on the left side of the slideway frame, a drilling mechanism is fixed on the slideway frame, the drilling mechanism is connected with the rear end of a chain assembly, and the front end of the chain assembly is installed in a middle cavity of the slideway frame. An impact type hydraulic rock drill is adopted, the ultra-high drilling capacity is achieved in a full-rock roadway or tunnel with the hardness larger than or equal to6, and the drilling efficiency is improved. The hydraulically-driven clamp holder has an automatic drill rod withdrawing function, and is rapid and convenient to use, and the labor intensity is reduced. The clamp holder and the positioning oil cylinder supply oil through hidden oil ways, the number of hydraulic rubber pipes is reduced, and the overall appearance is simple and clear.

Description

technical field [0001] The invention belongs to the technical field of rock bolt support equipment, and in particular relates to an impact hydraulic rock bolt drill, a control method and an application. Background technique [0002] At present, in the mining of metal mines and non-metal mines and the construction of hard rock tunnels for railways and highways and the construction of all-rock coal mine roadways, more and more support operations use bolt support methods for support operations. Most of the rock bolt rigs use the hydraulic motor to directly provide the torque for the bolt, and the hydraulic cylinder provides the thrust, so the drilling efficiency is low and the loss of the drill bit is large. In the bolting operation, it often happens that the drill pipe cannot be pulled out after being drilled, and it needs to be pulled out manually, which is labor-intensive. [0003] Through the above analysis, the existing problems and defects of the prior art are: most of t...

Problems solved by technology

[0002] At present, in the mining of metal mines and non-metal mines and the construction of hard rock tunnels for railways and highways and the construction of all-rock coal mine roadways, more and more support operations use bolt support methods for support operations. Most of the rock bolt rigs use the hydraulic motor to directly provide the torque for the bolt, and the hydraulic cylinder provides the thrust, the drilling efficiency is low, and the loss of the drill bit is large

In the bolting operation, the drill pipe often cannot be pulled out after being drilled, and it needs to be pulled out manually, which is labor-intensive

[0003] Through the above analysis, the problems and defects of the existing technology are: most of the existing rock bolt rigs exit the drill pipe after drilling and often fail to be drawn out, which requires manual extraction, which is labor intensive
