Description

Technical Field

[0001] The utility model relates to the field of ground drilling construction equipment, in particular to a drill rod grabbing and loading and unloading device for horizontal directional drilling. Background Art

[0002] A horizontal directional drill (HDD) is a construction machine used to lay a variety of underground utilities without excavating the ground. It is widely used in the laying of flexible pipelines for water supply, electricity, telecommunications, natural gas, coal gas, and oil. Horizontal directional drilling technology combines directional drilling techniques from the oil industry with traditional pipeline construction methods. It offers advantages such as high speed, high precision, and low cost.

[0003] The drill rod of a horizontal directional drilling rig is composed of multiple sections of drill rods and a drill bit, which needs to be assembled before construction. In the existing construction process, the loading and unloading of the drill rod and the drilling rig are generally done manually or by hoisting. The staff uses the wire rope or clamps on the hoisting device to fix the drill rod and hoist the drill rod to a preset position for matching installation. However, it is inconvenient to position the drill rod using a hoisting device, and the staff needs to manually assist in positioning, which is inconvenient to operate. In addition, the efficiency of loading and unloading the drill rod is low, the labor intensity of the workers is high, and there are certain safety risks in hoisting and handling. This is an existing problem. Utility Model Content

The tightening cylinder is fixed on the bottom of the feeding rack, and the piston rod of the tightening cylinder is hinged on the bottom of the sub-claw. The tightening cylinder drives the sub-claw to open and close to clamp the drill rod.

[0008] Further optimized, when the output of the driving motor drives the loading rack to rotate toward the directional drill, the grabbing port and the directional drill are in a coaxial state.

[0009] Further optimized, the base is embedded in the track, a servo motor is also provided on the base, a roller is provided at the bottom of the base, the roller is located between the track and the base, and the output of the servo motor drives the base to move left and right on the track through the roller.

[0010] For further optimization, symmetrical positioning racks are provided on both sides of the track, the chucks of the pneumatic chuck are located on both sides of the track, and positioning teeth are fixed on the inner side walls of the chucks.

[0011] For further optimization, limiting rails are provided on both sides of the bottom of the track, limiting grooves are provided on the inner wall of the bottom of the base, and the base is embedded in the track through the limiting rails and the limiting grooves.

[0012] For further optimization, a stabilizing rod is fixed between the loading racks, and an anti-slip rubber layer is provided on the inner walls of the sub-claws and the mother claws.

[0013] For further optimization, a movable carrier is provided at the bottom of the base, one end of the base is hinged to the movable carrier, and a lifting cylinder is hinged between the other end of the base and the movable carrier.

[0014] The beneficial effects of the utility model are:

[0015] In this device, the directional drill is movably mounted on a track. A servo motor drives the base to move left and right, and a pneumatic chuck controls the engagement and release of the positioning teeth with the positioning rack. This allows the base to move freely or be fixed on the track, facilitating the positioning and installation of the drill rod after it is positioned. It can also be moved and fixed in position to facilitate subsequent construction. After the gripping assembly grasps the drill rod, the loading rack drives the drill rod to rotate, automatically aligning it with the directional drill, eliminating the need for manual positioning and reducing labor intensity and safety risks. The base is hinged to a carrier or platform, and the end where the directional drill is located can be lifted to facilitate tilting the directional drill during construction.
