The drill rod, a rotating device in the drilling rig, is the core component of the drilling rig. During the use of the drill rod, the quality of the drill rod is of vital importance, and the size of the drill rod straightness deviation directly affects the performance of the drill rod. Therefore, it is necessary to use a straightness detection tool to perform straightness detection on the drill rod.

[0003] A Chinese patent with publication number CN116592810B discloses a rotary drilling rig drill pipe straightness detection tool, including two left-right symmetrical shells, the inner end faces of the shells are provided with a semicircular drill pipe cavity with an opening facing inward; the present invention is directly arranged on the drilling rig, so that the straightness and circular run-out of the drill pipe can be detected without disassembling the drill pipe and without affecting the normal operation of the drilling rig, thereby improving practicality and saving time for disassembling and assembling the drill pipe. The surface friction force of the drill pipe is detected when it is lifted and lowered to judge the lubrication condition of the drill pipe surface, and the lubricating fluid on the drill pipe surface is automatically replenished, saving time for manual replenishment, and preventing the friction of the drill pipe from being too large and increasing the wear of the drill pipe. In addition, a vertical detection block is used to detect whether the drill pipe is in a vertical state, so as to facilitate the use of the drilling rig and improve the detection accuracy.
