[0002] A coal mine drill pipe is a tool used in underground coal mine drilling, primarily for drilling for water exploration, gas exploration, and geological exploration. It is made of high-quality carbon steel and is typically twisted in shape, suitable for use with electric coal drills. The main function of the coal mine drill pipe is to transmit torque and transport drilling fluid; by gradually lengthening the drill pipe, the wellbore is continuously deepened. It plays a vital role in underground coal mine drilling, enabling effective deep-hole drilling and featuring fast slag removal, low rotational resistance, and good wear resistance.

[0003] Traditional coal mine drill pipe clamping devices have the following drawbacks: (1) When using traditional coal mine drill rod clamping devices, the clamping devices are prone to deviation in fixing the coal mine drill rod, which causes the coal mine drill rod to be unable to be perpendicular to the ground, resulting in deviation and instability after the coal mine drill rod enters the ground. (2) When using a traditional coal mine drill pipe clamping device, the coal mine drill pipe will collide when it is placed into the clamping device, which can easily cause damage to the clamping device.
