Synchronous drilling device special for mine

Abstract

The invention discloses a synchronous drilling device special for mine. The synchronous drilling device special for mine comprises a top plate. A driving mechanism is arranged in the middle of the top plate. A drill stem and a drill bit are arranged on the driving mechanism. First synchronous auxiliary mechanisms are arranged on the two sides of the driving mechanism and provided with first ejecting pins. First synchronous damping blocks are arranged on the first ejecting pins respectively and make smooth contact with the drill stem. A rock powder pipe is arranged on the drill stem and comprises an inner pipe body and an outer pipe body. The drill stem is arranged in the inner pipe body. A damping device is arranged at the bottom of the drill stem. A connecting joint is arranged on the side wall of the lower portion of the inner pipe body and provided with elastic wedge-shaped clamping teeth. A connector is arranged on the side wall of the inner pipe body. A clamping groove is formed in the side wall of the outer pipe body. The strong resistance and vibration magnitude in the drilling process are relieved, rock powder produced in the underground drilling process can be effectively fished up, drilling speed and quality are improved, the service life of the drilling device is prolonged, and the drilling device has good safe use performance and meets actual use requirements.

Description

technical field [0001] The invention relates to hydrogeological drilling equipment for underground construction of coal mines, in particular to a special synchronous drilling equipment for mines. Background technique [0002] Mines that are mined underground sometimes need to call the inclined shafts, shafts, and adits in the underground development of mines as mines. Mine development has a significant and far-reaching impact on the overall production and construction of metal mines or coal mines. It is not only related to the amount of infrastructure construction of the mine, the initial investment and the speed of well construction, but more importantly, it will determine the production conditions and technology of the mine for a long time. Economic Indicators. Mine development is to excavate a series of shafts from the ground to the underground, leading to the mining area. The main problems that need to be solved in mine development are: correctly divide the mine field,...

AI Technical Summary

Problems solved by technology

At present, the rock powder in the borehole is flushed out by pressure injection of clear water during drilling, which is beneficial to drilling; but the drilling equipment for coal mines in the prior art still needs to be improved technically, and in the actual construction process Due to strong resistance, the drilling equipment will generate strong vibrations, which will affect the drilling efficiency and process of the drilling equipment, and the strong vibrations will easily cause the drill bit to break; in addition, the actual drilling process often encounters broken rock formations, and the drilling The rock powder inside cannot be flushed out smoothly, which seriously affects the drilling speed of the drilling equipment, and sometimes even causes drilling stuck accidents, etc.
