Synchronous drilling equipment special for mine

Abstract

The invention discloses synchronous drilling equipment special for a mine. The synchronous drilling equipment comprises a top plate, a driving mechanism is arranged in the middle of the top plate, the driving mechanism is provided with a drilling rod and a drill, first synchronous auxiliary mechanisms are arranged at the two sides of the driving mechanism, the first synchronous auxiliary mechanisms are provided first centres, both the first centres are provided with first synchronous damping blocks, and the first synchronous damping blocks are in smooth contact with the drilling rod; the drilling rod is provided with a rock dust pipe, and the rock dust pipe comprises an inner pipe and an outer pipe; the drilling rod is arranged inside the inner pipe, and a damping device is arranged at the bottom of the drilling rod; a connection link is arranged at the side wall of the lower portion of the inner pipe, the connection link is provided with an elastic wedge-shaped clamping tooth, a connector is arranged at the side wall of the inner pipe, and a clamping groove is formed in the side wall of the outer pipe. The synchronous drilling equipment special for the mine buffers strong resistance and shaking amplitudes exerted during drilling, rock dust generated in an under-shaft drilling process can be effectively fished up, the drilling speed is increased, the drilling quality is improved, the service life of the drilling equipment is prolonged, the synchronous drilling equipment has high safety using performance, and the actual using requirement is met.

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.
