[0002] Horizontal directional drilling (HDD), as a trenchless construction technique, has been widely used in the laying of flexible pipelines for water supply, electricity, telecommunications, natural gas, coal gas, and oil due to its advantages such as fast construction speed, minimal impact on the ground environment, and low cost. However, the lifting and support of the drill rod is a critical link in the HDD construction process, directly affecting construction efficiency and safety.

[0003] Currently, among existing drill pipe lifting devices, such as the patent with authorization announcement number CN218235071U, this utility model discloses a drill pipe lifting device for horizontal directional drilling, including a directional drilling machine, a drill pipe is provided on the surface of the directional drilling machine, a support seat is provided on the side of the directional drilling machine, and a first hinge seat is provided on the surface of the support seat.

[0004] However, it was found during use that the device had a poor fixing effect on the drill rod and reduced the reliability of its lifting function. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a drill pipe lifting device for horizontal directional drilling that improves the convenience and flexibility of use and enhances the stability and reliability of drill pipe lifting.

[0006] This utility model discloses a drill pipe lifting device for horizontal directional drilling, comprising a support arm and a support shaft, with the support shaft rotatably mounted on the support arm; it also includes an adjustment device, a power device, a V-shaped arm, and clamping components. The V-shaped arm is rotatably mounted on the outer wall of the support shaft, and multiple sets of clamping components are mounted on the V-shaped arm via the adjustment device. The adjustment device is used to move and adjust the multiple sets of clamping components. The lower part of the V-shaped arm is connected to the power device, which provides power for the rotation of the V-shaped arm. The drill pipe to be lifted is placed between the multiple sets of clamping components. The adjustment device moves the multiple sets of clamping components closer to each other, thereby clamping and fixing the drill pipe, thus improving the fixation stability of the drill pipe. Then, the power device pushes the lower part of the V-shaped arm, and the V-shaped arm, supported by the rotation of the support shaft, drives the multiple sets of clamping components to swing upward, thereby lifting the drill pipe upward. Simultaneously, the adjustment device moves the multiple sets of clamping components to move their positions synchronously, facilitating further lifting and transport of the drill pipe, improving the convenience of use, and enhancing the stability and reliability of the drill pipe lifting operation.

[0007] Preferably, the power unit includes a drive device, a base, a guide rail, a movable seat, a guide sleeve, a connecting shaft, and a guide column. The bottom end of the support arm is connected to the outer wall of the base. The guide rail is installed on the outer wall of the base. The movable seat is slidably installed on the guide rail. The guide sleeve is rotatably installed on the movable seat via the connecting shaft. The guide column is installed on the outer wall of the bottom of the V-arm and slides through the inside of the guide sleeve. The base is provided with a drive device, which provides power for the sliding of the movable seat. After multiple sets of clamping components clamp and fix the drill rod, the drive device drives the movable seat to move forward. After the movable seat moves forward, it drives the guide sleeve to move forward. At this time, the guide sleeve and the guide column slide together, so that the guide sleeve pushes the guide column forward during rotation. After the guide column moves forward, it drives the upper part of the V-arm to swing upward, thereby lifting and moving the drill rod upward, improving the reliability and stability of lifting the drill rod.

[0008] Preferably, the adjustment device includes a moving device, a sliding sleeve, a support plate, a first cylinder, and a top plate. The support plate is disposed on the outer wall of the V-arm, and both ends of the top plate are slidably mounted on the V-arm via the sliding sleeve. Multiple sets of first cylinders are mounted on the outer wall of the support plate, and the moving ends of the multiple sets of first cylinders are connected to the top plate. A moving device is disposed on the top plate, which is used to drive multiple sets of clamping components to move in opposite directions. When the V-arm swings upward to the designated position, the multiple sets of first cylinders push the top plate upward, thereby facilitating further upward lifting and movement of the drill rod and improving the flexibility of lifting height adjustment.

[0009] Preferably, the moving device includes a guide and a second cylinder. The guide is installed on the outer wall of the top plate, and multiple sets of clamping components are slidably installed on the guide. Multiple sets of second cylinders are respectively installed on the outer wall of the guide, and the moving ends of the multiple sets of second cylinders are connected to the multiple sets of clamping components. The multiple sets of second cylinders drive the multiple sets of clamping components to move, so that the multiple sets of clamping components clamp and fix the drill rod.

[0010] Preferably, the driving device includes a lead screw and a motor. The lead screw is rotatably mounted on the base, and the movable seat is screwed onto the lead screw. The motor is mounted on the outer wall of the base, and the output end of the motor is connected to the lead screw. The motor drives the lead screw to rotate, thereby driving the movable seat to move.

[0011] Preferably, it also includes an electromagnetic brake, which is installed on the outer wall of the base and connected to the lead screw; this improves the braking effect of the lead screw rotation and enhances the positioning reliability of the V-arm.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: the drill rod to be lifted is placed between multiple sets of clamping members, and the multiple sets of clamping members are moved closer to each other by the adjustment device, so that the multiple sets of clamping members clamp and fix the drill rod, thereby improving the fixing firmness of the drill rod. Then, the lower part of the V-shaped arm is pushed by the power device, and the V-shaped arm drives the multiple sets of clamping members to swing upward through the rotation support of the support shaft, so that the multiple sets of clamping members lift the drill rod upward. At the same time, the adjustment device moves the multiple sets of clamping members to move their positions synchronously, thereby facilitating the further lifting and transportation of the drill rod, improving the convenience of use, and improving the stability and reliability of the drill rod lifting use.

Then, the lower part of the V-shaped arm 3 is pushed by the power device. The V-shaped arm 3 drives the multiple sets of clamping members 4 to swing upward through the rotation support of the support shaft 2, so that the multiple sets of clamping members 4 lift the drill rod upward. At the same time, the adjustment device moves the multiple sets of clamping members 4 synchronously, so as to facilitate further lifting and transportation of the drill rod, improve the convenience of use, and improve the stability and reliability of the drill rod lifting use. Example 2

[0024] Based on Example 1, such as Figure 2 As shown, this utility model discloses a drill rod lifting device for horizontal directional drilling. The adjusting device includes a moving device, a sliding sleeve 11, a support plate 12, a first cylinder 13, and a top plate 14. The support plate 12 is disposed on the outer wall of the V-shaped arm 3. Both ends of the top plate 14 are slidably mounted on the V-shaped arm 3 through the sliding sleeve 11. Multiple sets of first cylinders 13 are mounted on the outer wall of the support plate 12. The moving ends of the multiple sets of first cylinders 13 are connected to the top plate 14. The top plate 14 is provided with a moving device, which is used to drive multiple sets of clamping parts 4 to move in opposite directions.

[0025] like Figure 3As shown, the moving device includes a guide 15 and a second cylinder 16. The guide 15 is installed on the outer side wall of the top plate 14.

The multiple sets of clamping members 4 are moved closer to each other by an adjusting device, so that the multiple sets of clamping members 4 clamp and fix the drill rod, thereby improving the fixation of the drill rod. Then, the lower part of the V-shaped arm 3 is pushed by a power device. The V-shaped arm 3 drives the multiple sets of clamping members 4 to swing upward through the rotation support of the support shaft 2, so that the multiple sets of clamping members 4 lift the drill rod upward. At the same time, the adjusting device moves the multiple sets of clamping members 4 synchronously, thereby further lifting and transporting the drill rod.
