Description

Technical Field

[0001] This utility model relates to the field of tubing power clamp technology, and more specifically, to a protection mechanism for tubing power clamps. Background Technology

[0002] Hydraulic power pliers are tools widely used in the oil and gas industry, construction, maintenance, and other heavy machinery operations. They are mainly used to tighten or loosen large bolts, connectors, and various pipe joints. Their core working principle is based on a hydraulic system, utilizing the pressure of fluid within a sealed space to transmit force, thereby achieving high torque output. Hydraulic power pliers consist of a hydraulic pump, cylinder, piston, jaws, valves, and a control system. Their working process involves the hydraulic pump delivering hydraulic oil to the cylinder, pushing the piston in a linear motion, which in turn causes the jaws to clamp or loosen the target object.

[0003] In actual use, hydraulic power pliers generally use the jaws to clamp oil pipes individually. This can lead to the jaws breaking when clamping large oil pipes due to the lack of stability in single clamping, making subsequent work impossible and affecting work efficiency. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a protection mechanism for a hydraulic hose power clamp that overcomes or at least partially solves the above technical problems.

[0005] This utility model is implemented as follows:

[0006] This utility model provides a protective mechanism for a hydraulic hose power clamp, including a main housing, a hydraulic oil pump installed on the top surface of the main housing, a clamping jaw provided on one side of the hydraulic oil pump, an equipment cavity opened on the front surface of the main housing, and a protective clamping mechanism and an adjustment mechanism provided inside the equipment cavity.

[0007] The protective clamping mechanism includes a mounting plate, one end of which is located inside the equipment cavity. A motor is fixedly mounted on the bottom surface of the mounting plate, and the output end of the motor extends to the top surface of the mounting plate. A half gear is fixedly connected to the end of the motor that extends to the top surface of the mounting plate.

[0008] In a preferred embodiment, a plug-in post is fixedly installed on the top surface of the mounting plate, and a second half-gear is rotatably installed on the top end of the plug-in post, the second half-gear meshing with the first half-gear.

[0009] In a preferred embodiment, the outer surfaces of the first half gear and the second half gear are respectively fixedly connected to the swing arm first and the swing arm second, and the top surface of the mounting plate is fixedly installed with a column, and the top of each column is movably connected to a connecting arm.

[0010] In a preferred embodiment, a clamping arm is provided below both the first swing arm and the second swing arm. One end of the clamping arm is movably connected to one end of the first swing arm and the second swing arm, respectively, and the middle part of the clamping arm is movably connected to the bottom surface of the connecting arm.

[0011] In a preferred embodiment, the adjustment mechanism includes a second motor, which is fixedly installed on the top surface inside the equipment cavity, and a threaded rod is fixedly connected to the output end of the second motor.

[0012] In a preferred embodiment, the top surface of the mounting plate has a threaded hole, and the threaded rod is threadedly sleeved inside the threaded hole.

[0013] In a preferred embodiment, limit plates are fixedly installed on both sides of the mounting plate. The limit plates have positioning holes inside, and limit posts are movably inserted into the positioning holes. The two ends of the limit posts are fixedly connected to the inner walls of both sides of the equipment cavity.

[0014] In a preferred embodiment, positioning plates are fixedly installed on both sides of the main housing, and mounting holes are provided on the top surface of each positioning plate.

[0015] The protective mechanism for a hydraulic hose power clamp provided by this utility model has the following beneficial effects:

[0016] 1. By setting up a protective clamping mechanism, the start of motor one can drive half gear one to rotate. Since swing arm two and swing arm one are connected to the two clamping arms, under the action of the connecting arm and the column, the two clamping arms below can be driven to move in opposite directions, which can realize the auxiliary clamping of the oil pipe. Thus, after the jaws clamp the oil pipe, the two clamping arms can also provide auxiliary clamping of the oil pipe, preventing the jaws from being damaged due to excessive torque.

[0017] 2. By setting an adjustment mechanism and controlling the second motor to start, the threaded rod can be driven to rotate during the second motor start-up process. Since the threaded rod is installed inside the threaded hole, when the threaded rod rotates, it can drive the mounting plate to move up and down inside the equipment cavity under the action of the threaded rod and the threaded hole, thereby realizing the height adjustment of the protective clamping mechanism and the height adjustment of the oil pipe auxiliary clamping.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] Reference Figures 1-4 This utility model provides a technical solution: a protective mechanism for a hydraulic hose power clamp, including a main housing 1, a hydraulic oil pump 2 installed on the top surface of the main housing 1, a clamping jaw 3 provided on one side of the hydraulic oil pump 2, an equipment cavity 6 opened on the front surface of the main housing 1, and a protective clamping mechanism 7 and an adjustment mechanism 8 provided inside the equipment cavity 6.

[0026] Positioning plates 4 are fixedly installed on both sides of the main housing 1. The top surface of the positioning plates 4 is provided with mounting holes 5. Through the positioning plates 4 and mounting holes 5, the device can be installed stably, making the device more stable in actual use.

[0027] The protective clamping mechanism 7 includes a mounting plate 701, one end of which is located inside the equipment cavity 6. A motor 710 is fixedly mounted on the bottom surface of the mounting plate 701. The output end of the motor 710 extends to the top surface of the mounting plate 701. A half gear 703 is fixedly connected to the end of the motor 710 extending to the top surface of the mounting plate 701. A plug-in post 704 is fixedly mounted on the top surface of the mounting plate 701. A second half gear 703 is rotatably mounted on the top of the plug-in post 704. 05. Half gear 2 705 meshes with half gear 1 703. Swing arm 1 702 and swing arm 2 706 are fixedly connected to the outer surfaces of half gear 1 703 and half gear 2 705, respectively. A column 707 is fixedly installed on the top surface of the mounting plate 701. A connecting arm 708 is movably connected to the top of each column 707. A clamping arm 709 is provided below each of the swing arms 1 702 and swing arm 2 706. One end of the clamping arm 709 is connected to the swing arm 1 702. One end of the second swing arm 706 is movably connected, and the middle part of the clamping arm 709 is movably connected to the bottom surface of the connecting arm 708. During the process of using the jaws 3 to clamp the oil pipe, the starting of the motor 710 can drive the half gear 703 to rotate. During the rotation, it can drive the half gear 705 that meshes with it to rotate, thereby driving the swing arms 702 and 706 to move. Since the swing arms 706 and 702 are connected to the two clamping arms 709, under the action of the connecting arm 708 and the column 707, the two clamping arms 709 below them can move towards each other until the two clamping arms 709 clamp the oil pipe. This achieves auxiliary clamping of the oil pipe, thus enabling the two clamping arms 709 to provide auxiliary clamping of the oil pipe after the jaws 3 clamp it, preventing the jaws 3 from being damaged due to excessive torque.

[0028] The adjustment mechanism 8 includes a second motor 801, which is fixedly installed on the top surface inside the equipment cavity 6. A threaded rod 802 is fixedly connected to the output end of the second motor 801. A threaded hole 805 is provided on the top surface of the mounting plate 701, and the threaded rod 802 is threadedly sleeved inside the threaded hole 805. Limiting plates 804 are fixedly installed on both sides of the mounting plate 701. Positioning holes are provided inside the limiting plates 804, and limiting posts 803 are movably inserted into the positioning holes. The two ends of the limiting posts 803 are fixedly connected to the inner walls of both sides of the equipment cavity 6. Therefore, when the position of the protective clamping mechanism 7 needs to be adjusted, the second motor 801 is first started. During the starting process of the second motor 801, it can... When the threaded rod 802 rotates, it rotates inside the threaded hole 805. Therefore, when the threaded rod 802 rotates, it can drive the mounting plate 701 to move up and down inside the equipment cavity 6 under the action of the threaded rod 802 and the threaded hole 805. This allows for height adjustment of the protective clamping mechanism 7, that is, the height of the oil pipe auxiliary clamping, which greatly increases the overall practicality of the device. Furthermore, when the mounting plate 701 moves up and down inside the equipment cavity 6, it also allows the limiting post 803 to move inside the limiting plate 804. The limiting plate 804 makes the mounting plate 701 more stable when moving up and down inside the equipment cavity 6.

[0029] Specifically, the working process or principle of the protection mechanism of this type of hydraulic hose power clamp is as follows: During use, starting the motor 710 drives the half-gear 703 to rotate. During this rotation, the half-gear 705 meshing with it rotates, thereby causing the swing arms 702 and 706 to move. Since the swing arms 706 and 702 are connected to the two clamping arms 709, under the action of the connecting arm 708 and the column 707, the two clamping arms 709 below them can move towards each other until the two clamping arms... After the clamping arm 709 clamps the oil pipe, it can achieve auxiliary clamping of the oil pipe. By controlling the start of the second motor 801, the threaded rod 802 can be driven to rotate during the start-up process of the second motor 801. Since the threaded rod 802 is installed inside the threaded hole 805, when the threaded rod 802 rotates, it can drive the mounting plate 701 to move up and down inside the equipment cavity 6 under the action of the threaded rod 802 and the threaded hole 805. This can achieve the height adjustment of the protective clamping mechanism 7, that is, the height of the auxiliary clamping of the oil pipe can be adjusted.

[0030] It should be noted that motor 710 and motor 801 are existing devices or equipment, or devices or equipment that can be implemented with existing technology. Their power supply, specific composition and principle are clear to those skilled in the art, so they will not be described in detail.
