Description

Technical Field

[0001] This utility model relates to the field of hydraulic tool technology, specifically to an easily adjustable hydraulic power pliers. Background Technology

[0002] Hydraulic power tongs are mechanized tools driven by hydraulic transmission technology, specifically designed for oilfield well workover operations. They are used to quickly and safely load and unload tubing and similar pipe threads. By converting hydraulic oil pressure energy into mechanical energy, they achieve high torque output, facilitating rapid alignment of pipe threads and adapting to different pipe diameter requirements. They integrate speed change, rotation direction control, and automatic notch alignment functions to improve operational efficiency. They are equipped with a braking system and safety valves to prevent accidents.

[0003] The working principle of hydraulic power tongs: Hydraulic oil from the workover rig enters the hydraulic motor through the control valve, driving the motor to rotate. The motor output shaft reduces the speed and increases the torque through the reducer, which is then transmitted to the open gear. When the open gear rotates, the jaw plate frame is fixed by the braking system, and the track slope pushes the jaw plate rollers up the slope, causing the tongs to move towards the center of the tubing and bite. The tong head forms a rigid connection with the tubing, driving the tubing to rotate to complete the engagement or disengagement. After the operation is completed, the braking system is released, and the jaw plate returns to its initial position under the action of the return spring.

[0004] However, traditional hydraulic power pliers have the problem of inconvenience in adjusting the tilt angle of the upper and lower clamps when assembling or disassembling pipes with different tilt angles. This limits the applicability of hydraulic power pliers and reduces the efficiency of pipe loading and unloading. Therefore, developing a hydraulic power pliers that can easily adjust the tilt angle of the clamps is of great practical significance. Utility Model Content

[0005] The purpose of this invention is to provide an easily adjustable hydraulic power clamp to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an easily adjustable hydraulic power clamp, comprising a housing, an upper clamp body and a lower clamp body rotatably mounted on the outer surface of the housing, a control box and a drive motor fixedly mounted on the upper surface of the housing, a protective baffle hinged to the opening of the lower clamp body, a handle fixedly connected to the outer surface of the protective baffle, an adjustment component fixedly connected to the bottom of the housing, and a moving component fixedly connected to the side of the adjustment component away from the housing.

[0007] Preferably, the moving component includes a support block fixedly installed at the bottom of the adjusting component, an mounting plate fixedly connected to the outer wall of the support block, a drive wheel rotatably connected to the side of the mounting plate away from the support block, and a plurality of driven wheels rotatably connected to the outer wall of the mounting plate. Tracks are fitted onto the outer walls of the drive wheel and the driven wheels.

[0008] Preferably, the adjustment assembly includes a top plate fixedly connected to the bottom of the housing, an upper connecting seat 1 fixedly connected to the side of the top plate away from the housing, a lower connecting shaft rotatably connected to the inner wall of the upper connecting seat 1, and a lower connecting seat rotatably connected to the end of the lower connecting shaft away from the upper connecting seat 1.

[0009] Preferably, a base plate is fixedly connected to the side of the lower connecting seat away from the lower connecting shaft, an mounting box is fixedly installed on the upper surface of the base plate, a threaded rod is rotatably connected to the inner wall of the mounting box, a threaded block is threadedly connected to the outer wall of the threaded rod, and a drive motor for driving the threaded rod to rotate is fixedly installed on the outer wall of the mounting box.

[0010] Preferably, a groove is provided through the outer wall of the mounting box, a slider is slidably connected to the inner wall of the groove, the side of the slider away from the groove is fixedly connected to the outer wall of the threaded block, and a fixed shaft is fixedly connected to the side of the slider away from the threaded block.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: after the device is moved to the work site by the moving component, the drive motor is started to drive the threaded rod to rotate, which drives the threaded block to move along the axial direction of the slide groove. As the threaded block moves, it pushes the connecting shaft below the top plate to rotate around the axis through the connecting rod, thereby adjusting the tilt angle of the top plate. This adjusts the tilt angle between the upper clamp and the lower clamp in the device, so that the device can assemble or disassemble pipes with different tilt angles, which greatly improves the loading and unloading efficiency of pipes.

The moving component 7 is used to move the device to the work area. The adjustment component 6 is used to adjust the tilt angle between the upper clamp 4 and the lower clamp 8.

[0022] The moving component 7 includes a support block 71 fixedly installed at the bottom of the adjusting component 6. The support block 71 has an installation groove, and a drive motor 3 for driving the drive wheel 73 to rotate is fixedly installed in the installation groove. An installation plate 72 is fixedly connected to the outer wall of the support block 71. The drive wheel 73 is rotatably connected to the side of the installation plate 72 away from the support block 71. Several driven wheels 75 are rotatably connected to the outer wall of the installation plate 72. Tracks 74 are fitted on the outer walls of the drive wheel 73 and the driven wheels 75.

[0023] When in use, the drive motor is started to drive the drive wheel 73 to rotate, which in turn drives the driven wheel 75 to drive the track 74 to rotate, thereby moving the equipment. The equipment is then moved to the work site via the moving component 7. The drive motor 2 drives the upper clamp 4 and the lower clamp 8 to loosen the threaded connection of the pipe, thus facilitating the assembly or disassembly of the pipe.

[0024] Example 2: The adjustment assembly 6 includes a top plate 65 fixedly connected to the bottom of the housing 1. An upper connecting seat 69 is fixedly connected to the side of the top plate 65 away from the housing 1. A lower connecting shaft 610 is rotatably connected to the inner wall of the upper connecting seat 69. A lower connecting seat 611 is rotatably connected to the end of the lower connecting shaft 610 away from the upper connecting seat 69. A bottom plate 61 is fixedly connected to the side of the lower connecting seat 611 away from the lower connecting shaft 610. An installation box 62 is fixedly installed on the upper surface of the bottom plate 61. A threaded rod 66 is rotatably connected to the inner wall of the installation box 62. A threaded block 64 is threadedly connected to the outer wall of the threaded rod 66.

[0026] In use, the drive motor 63 is started to drive the threaded rod 66 to rotate, which drives the threaded block 64 to move axially along the slide groove 612. As the threaded block 64 moves, it pushes the connecting shaft 610 below the top plate 65 to rotate around the axis through the connecting rod 613, thereby adjusting the tilt angle of the top plate 65. This adjusts the tilt angle between the upper clamp 4 and the lower clamp 8 in the device, allowing the device to assemble or disassemble pipes with different tilt angles, greatly improving the efficiency of pipe loading and unloading.
