The invention belongs to the field of drilling equipment in coal mines, and relates to an auxiliary rod loading device for a directional drilling machine. The auxiliary rod loading device comprises aguide rail assembly, a mounting frame, driven wheels, a rotating mechanism, a friction wheel, a carrier wheel mechanism, a propulsion oil cylinder, a rotating oil cylinder and a driving motor, whereina directional drilling rod is placed on the driven wheels; the directional drilling rod is leveled through the carrier wheel mechanism; and the rotating oil cylinder pushes the friction wheel to press the directional drilling rod, and the driving motor drives the friction wheel to rotate, so as to apply a certain rotating torque to the directional drilling rod to achieve initial pre-tightening ofthe directional drilling rod. In a rod loading process, the propulsion oil cylinder is in a floating state, so as to protect a screw thread of the directional drilling rod; and after the rod loadingis completed, the propulsion oil cylinder returns back for the next pre-tightening. The auxiliary rod loading device is simple in structure, small in size, low in cost and favorable for maintenance and wear-out part replacement; the efficiency of pre-tightening the directional drilling rod is improved; the labor intensity of a worker is substantially reduced; and the safety problem of the worker in a large-diameter directional drilling rod pre-tightening process is avoided.
Description
technical field [0001] The invention belongs to the field of underground drilling equipment in coal mines, and relates to an auxiliary upper rod device for a directional drilling machine. Background technique [0002] In recent years, with the improvement of mine mining capacity, 10-million-ton mines and million-ton working faces have increased significantly, and the amount of gas gushing out of working faces has increased year by year, seriously restricting the safety of underground coal mine production and the improvement of mine production efficiency. As a clean energy source, efficient extraction and utilization of gas will produce considerable economic benefits and greatly alleviate the energy shortage in our country. [0003] At present, the diameter of the directional drill pipe has reached 127mm, which has increased significantly compared with before, and the weight has also increased significantly. If the traditional small-diameter directional drilling machine "shou...
