Description

Technical Field

[0002] Trenchless horizontal directional drilling is a technology for laying underground pipelines without excavating the surface. Pipes or cables are laid by drilling holes at small angles and expanding the holes. This technology has fast construction speed and high precision and can be applied to a variety of geological and complex terrains. It is widely used in urban pipeline networks and river crossing projects. In order to facilitate the operation of horizontal directional drilling, a trenchless horizontal directional drilling power unit is required.

[0029] Working principle: by storing the unused drill rods in the storage pocket 201, when assembly is required, the motor 206 is started to drive the gear rod 207 to rotate, and at this time, through the meshing with the tooth groove 205, the push plate 203 can be pushed out of the storage bucket 201. At the same time, with the movement of the push plate 203 and the push of the mountain-shaped groove 204 on it during movement, the baffle plate 202 can be lifted during movement, and the drill rod inside will be discharged along the push plate 203 when the baffle plate 202 is lifted. At this time, the transmission of the belt 210 can synchronously drive the hollow plate 209 to rotate along the left side of the inside of the hollow frame 5 when the gear rod 207 rotates. At this time, the hollow frame 5 rotates inside, so that the holes between the hollow plate 209 and the hollow frame 5 intersect and interlace, so as to fix the drill rod at that place, so as to facilitate the assembly of subsequent drill rods. When the old drill rod is fixed and the new drill rod is in place, the mobile installation frame 9 can push and drive the new drill rod to rotate to assemble it with the old drill rod; And starting the electric telescopic rod 304 can drive the rotating block 314 to move, so as to pull the telescopic block 305 to rotate, thereby pulling the clamping plate 307 to move along the groove plate 306, so as to fix the drill rods of different specifications and thicknesses in the positioning cover 308, and then starting the motor 1 301 to drive the circular gear 302 to rotate, so as to drive the gear ring 303 and the positioning cover 308 to rotate through meshing, so as to drive them to rotate when fixing drill rods of different specifications; Finally, by starting the second motor 402, the rotating plate 401 can be driven to rotate along the base 1, and then the electric guide rail 404 is started to push the U-shaped block 405 to move left and right, so as to push the telescopic plate 406 to move and rotate. At this time, the hollow frame 5 and the structure thereon are pushed to rotate through the rotation and extension of the telescopic plate 406, so as to adjust the angle of the device as needed. Subsequently, the electric wheel 410 is started and the transmission belt 407 is used to improve the stability of the electric wheel 410 during rotation. At this time, as the electric wheel 410 rotates, the threaded block 408 thereon will be driven to rotate synchronously, so as to push the plug-in block 409 to move, so as to plug and fix the device, which can facilitate the fixation of the device and adjust the angle as needed.
