Description

Technical Field

[0001] The invention relates to the technical field of hydraulic drilling rigs, in particular to a column-type hydraulic rotary drilling rig used for coal mine drilling. Background Art

[0002] In the field of coal mining, drilling operations are an indispensable part. With the continuous advancement of mining technology and the increasing requirements for safe production, the demand for drilling equipment is also increasing. As an efficient, safe and reliable drilling equipment, the frame-type hydraulic rotary drilling rig has gradually become one of the important equipment in the field of mining because it can adapt to complex geological conditions, provide stable power output and precise drilling control. The frame-type hydraulic rotary drilling rig adopts advanced hydraulic transmission technology and modular design concepts. The hydraulic transmission system can provide stable and adjustable power output, so that the drilling rig can maintain efficient operating performance under different geological conditions. At the same time, the modular design makes the installation, disassembly and maintenance of the equipment more convenient and quick, and also allows users to flexibly configure the various components of the drilling rig, such as drill rods, drill bits, etc., according to specific operating requirements to adapt to different drilling tasks.

[0003] The existing column-type hydraulic rotary drilling rig has the following defects: First, at present, the column-type hydraulic rotary drilling rig is often limited by its huge size and complex structure when facing the change of the working site, and it is difficult to move quickly and conveniently. Usually, the operator needs to disassemble the various modules of the drilling rig and then transport them one by one to the new working site for reinstallation. This process is not only time-consuming and labor-intensive, but also increases the risk of equipment damage and operation interruption, which greatly affects the operation efficiency and continuity; second, the underground working environment such as coal mines is complex and changeable, with small space and undulating terrain, which puts extremely high demands on the stability of the drilling rig. However, the traditional column support method is often difficult to provide sufficient stability and support force when facing complex terrain, which may cause the drilling rig to shake or tilt during the operation, thereby affecting the accuracy and safety of drilling; third, in the drilling operation, positioning accuracy is one of the important indicators to measure the performance of the drilling rig. However, during the drilling process, the existing column-type hydraulic rotary drilling rig is often difficult to ensure high-precision positioning due to the vibration of the drill bit and the stability of the drilling rig itself. This will not only reduce the quality of the borehole, but may also pose a potential threat to the safe production of the mine, such as gas leakage or water damage caused by drilling deviation.
