Description

Technical Field

[0001] The invention relates to the field of drilling technology and equipment, and in particular to a detachable drill rod box for high-position drilling construction of an electric drilling rig and a use method thereof. Background Art

[0002] As an important part of ensuring safe and efficient production in coal mines, underground tunnel drilling rigs in coal mines have played an important role in efficient gas extraction, advanced drainage of roof, grouting reinforcement of floor waterproof layer, and exploration of hidden geological factors that cause disasters underground. In recent years, in order to achieve the goal of "mechanized reduction of manpower, automated replacement of manpower, and intelligent unmanned" in underground coal mines, electric drilling rigs have become increasingly popular due to their advantages such as high transmission efficiency, good operability, high control accuracy and responsiveness. Electric drilling rigs usually have an automatic loading and unloading drill rod device, which consists of a manipulator and a drill rod box, which greatly reduces the labor intensity of workers and improves the efficiency of drilling construction. However, during the construction of high-position drilling (2m~4m), the following problems exist: ① The size of the drill rod box is fixed and cannot be flexibly disassembled and assembled. After it is filled with drill rods, the overall weight is large, and it is difficult to relocate and move underground; ② The drill rod box has no drill rod lifting mechanism. When the manipulator grabs the bottom drill rod, the extension distance is long and the force condition is poor, which is prone to structural damage; ③ After the drill rods in the drill rod box are drilled, personnel need to climb up to load the drill rod box. If they are standing unsteadily or operating improperly, safety accidents are very likely to occur.

[0003] To this end, in view of the above-mentioned defects, the designers of the present invention have concentrated on research and design, combined with the experience and achievements of many years in related industries, and have researched and designed a detachable drill rod box and a method of use for high-position drilling construction of an electric drilling rig to overcome the above-mentioned defects.
