The invention relates to a drill stem straightness detection device of a trenchless pipe laying drill stem. The drill stem straightness detection device comprises a cross beam, a left support component and a right support component, wherein the cross beam, the left support component and the right support component are connected by using bolts; the left support component is arranged at the left end of the cross beam; the right support component is arranged at the right end of the cross beam; a driving roller and a second driven roller of the left support component form a left V-shaped included angle; two first driven rollers of the right support component form a right V-shaped included angle; the left V-shaped included angle and the right V-shaped included angle form two supporting points; and a drill stem is horizontally placed on the detection device for detection. The right support component can be adjusted and arranged at a proper position on the cross beam according to the length of the drill stem, so that the detection requirements of the drill stems of different lengths can be met, thereby reducing the manpower and material resources and realize quickness and effectiveness.
Description
technical field [0001] The invention relates to a straightness detection device of a non-excavation pipe laying drill pipe, which belongs to the field of engineering machinery. Background technique [0002] In the technical field of trenchless engineering machinery, the drill pipe is the main component of the construction operation of the trenchless pipelaying rig, and mainly completes the transmission of torque during the horizontal directional drilling process. It is very important to choose a high-quality drill pipe, and the straightness deviation of the drill pipe directly affects the performance of the drill pipe. If the straightness deviation of the drill pipe is too large, the drill pipe will produce torsional vibration during the drilling process, which will directly Affect the success rate of non-excavation engineering construction, and accelerate the wear of the drill pipe and cause the drill pipe to fail. Therefore, after the drill pipe is processed, it is usuall...
