Description

Technical Field

[0001] The utility model relates to the technical field of chuck valve wrenches, and particularly relates to a chuck valve wrench. Background Art

[0002] In the industrial field, the operation of underground valve switches is a crucial link. Underground valve switches are usually used to control the transportation of fluids such as oil, natural gas, water, etc., and their normal operation is directly related to the safety and stability of the entire transportation system. However, due to the long-term underground environment of underground valve switches, their operation faces many challenges.

[0003] At present, there are many types of driving devices for underground valve switches, but most of them have some obvious defects. On the one hand, the traditional driving devices are not reasonably designed in terms of structure, resulting in difficulty in flexible operation in the narrow underground space. For example, the grip of some driving devices is not designed reasonably, and it is difficult for operators to accurately control the driving device in the underground environment, affecting the operation efficiency of the valve switch.

[0004] On the other hand, when adjusting the clamping force of the chuck on the valve switch, the existing driving devices often lack an effective adjustment mechanism. The chucks of some driving devices can only perform simple opening and closing operations and cannot adjust the size of the clamping force according to the actual situation of the valve switch, which may lead to insecure clamping of the chuck on the valve switch, thus affecting the normal operation of the valve switch.

[0005] Therefore, it is necessary to design a chuck valve wrench to solve the above problems. Content of the Utility Model

[0006] The purpose of the utility model is to solve the defects existing in the prior art, and a chuck valve wrench is proposed. Through the setting of an adjusting component and a pressing component, the chuck can be flexibly adjusted according to actual needs to achieve stable clamping of the valve switch. And on one side of a chuck close to the axis of the rotating seat, a strengthening key is provided, which can better be stuck in the groove of the valve to ensure the stability after clamping.

[0007] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0008] A chuck valve wrench includes a handle and a drive motor. A square head is fixedly connected to the end of the output shaft of the drive motor. A short reaction arm is provided at the upper end of the square head. A connector is fixedly connected to the upper end of the square head through the short reaction arm. A rotating seat is fixedly connected to the upper end of the connector. Three sliding grooves are provided at the upper end of the rotating seat. A slider is slidably connected in each of the three sliding grooves. A pawl is fixedly connected to the upper end of each slider. An adjustment assembly is provided on the outer side of the rotating seat. The adjustment assembly includes multiple L-shaped blocks disposed on the outer wall of the rotating seat. A telescopic rod is fixedly connected to the side of each L-shaped block near the rotating seat. The telescopic end of each telescopic rod is fixedly connected to a corresponding slider. Each slider is elastically connected to the adjacent side of the corresponding L-shaped block by a spring.

[0009] Preferably, the grip is fixedly connected to the outside of the drive motor via a connector, a control switch is installed at the upper end of the grip, a power supply is provided inside the grip, and the power supply, control switch and drive motor are electrically connected via wires.

[0010] Preferably, each of the adjusting components is further provided with a clamping component, the clamping component including two fixing rods fixedly connected to the L-shaped block, the upper ends of the two fixing rods being fixedly connected to a vertical plate, the vertical plate having a stop block on the side near the L-shaped block, the stop block having a threaded hole on the side near the vertical plate, a bolt being rotatably connected to the vertical plate, the bolt extending into the threaded hole on the side near the stop block, and the side of the stop block near the L-shaped block being an inclined surface.

[0011] Preferably, each of the abutments has a guide groove on the side near the vertical plate, and two guide rods are fixedly connected to each vertical plate. The two guide rods extend into the guide groove and are slidably connected to the inner wall of the guide groove.

[0012] Preferably, a reinforcing key is fixedly connected to one of the pawls on the side near the axis of the rotating seat.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example 1

[0026] Reference Figures 1-3A chuck valve wrench includes a handle 1 and a drive motor 2. The handle 1 provides a grip for the operator. A square head 3 is fixedly connected to the end of the output shaft of the drive motor 2. A short reaction arm 4 is provided at the upper end of the square head 3. The short reaction arm 4 increases the stability during rotation and plays a fixing role when installing the carbon fiber rod, ensuring the smooth operation of the drive motor 2. A connector 5 is fixedly connected to the upper end of the square head 3 through the short reaction arm 4. A rotating seat 6 is fixedly connected to the upper end of the connector 5. The upper end of the rotating seat 6 is provided with three sliding grooves 19. A slider 11 is slidably connected in each of the three sliding grooves 19. Each slider 11 has a claw 7 fixedly connected to its upper end. The claw 7 is used to clamp the valve switch and is a component that directly contacts the valve switch to achieve the clamping operation. The arc surface design of its upper end helps to better automatically fit the valve switch. An adjustment component is provided on the outside of the rotating seat 6. The adjustment component includes multiple L-shaped blocks 8 set on the outer wall of the rotating seat 6. Each L-shaped block 8 is fixedly connected to a telescopic rod 9 on the side near the rotating seat 6. The telescopic end of each telescopic rod 9 is fixedly connected to the corresponding slider 11. Each slider 11 is elastically connected to the adjacent side of the corresponding L-shaped block 8 by a spring 10. The upper end of each claw 7 is an arc surface.

[0027] The handle 1 is fixedly connected to the outside of the drive motor 2 via a connector. A control switch 20 is installed at the upper end of the handle 1. A power source is installed inside the handle 1. The power source, control switch 20, and drive motor 2 are electrically connected via wires. The power source inside the handle 1 provides power to the drive motor 2. The wires realize the electrical connection between the power source, control switch 20, and drive motor 2, so that the control switch 20 can control the power supply to the drive motor 2, thereby controlling the operation of the drive motor 2.

[0028] Each adjusting component is also equipped with a clamping component, which includes two fixing rods fixedly connected to the L-shaped block 8. The upper ends of the two fixing rods are jointly fixedly connected to a vertical plate 12. A stop block 14 is provided on the side of the vertical plate 12 near the L-shaped block 8. A threaded hole 15 is provided on the side of the stop block 14 near the vertical plate 12. A bolt 13 is rotatably connected to the vertical plate 12. The side of the bolt 13 near the stop block 14 extends into the threaded hole 15. The threaded hole 15 engages with the bolt 13, allowing the bolt 13 to rotate and drive the stop block 14 to move. The key structure for the movement of the abutment block 14 is that the side of the abutment block 14 closest to the L-shaped block 8 is inclined. The inclined design allows the abutment block 14 to effectively squeeze the slider 11 when it moves. The movement of the abutment block 14 is converted into pressure on the slider 11 through the action of the inclined surface, thereby realizing the adjustment of the clamping force of the claw 7. Each abutment block 14 is provided with a guide groove 17 on the side closest to the vertical plate 12. Two guide rods 16 are fixedly connected to each vertical plate 12. Both guide rods 16 extend into the guide groove 17 and slide in connection with the inner wall of the guide groove 17.

[0029] One of the jaws 7 is fixedly connected to a reinforcing key 18 on the side near the axis of the rotating seat 6. The reinforcing key has been hardened and has high strength. In actual use, the reinforcing key can better fit into the groove of the valve, ensuring that the wrench can be locked tightly with the valve during operation.

[0030] The functional principle of this utility model can be explained through the following operation: First, align the chuck valve wrench with the valve. The upper end of each chuck 7 is an arc surface. When the chuck 7 is pressed against the valve switch, multiple chucks 7 will move away from the rotating seat 6. As it continues to press forward, the chucks 7 will first separate from the valve switch and then clamp onto the outside of the valve switch. At this time, under the action of the spring 10, the chucks 7 and the valve switch are initially pressed together.

[0031] When the bolt 13 is rotated, the side of the bolt 13 near the abutment 14 extends into the threaded hole 15 of the abutment 14. The side of the abutment 14 near the vertical plate 12 is provided with a guide groove 17, and the two guide rods 16 fixedly connected on the vertical plate 12 extend into the guide groove 17 and slide in connection with the inner wall of the guide groove 17, thereby causing the abutment 14 to move towards the slider 11.

[0032] Since the side of the abutment 14 closest to the L-shaped block 8 is inclined, the abutment 14 will squeeze the slider 11 when it moves. The slider 11 is slidably connected in the groove 19 of the rotating seat 6. The upper end of the slider 11 is fixedly connected to the claw 7. The slider 11 moves the claw 7 to squeeze the valve switch, so that the claw 7 can press tightly on the valve switch. At this time, the reinforcing key 18 will enter the valve groove.

[0033] At this point, the staff can control the drive motor 2 to run, which drives the rotating seat 6 and the pawl 7 to rotate through the square head 3 and the connector 5, thereby opening or closing the valve;

[0034] It is worth mentioning that during operation, the carbon fiber rod needs to be fixed on the short reaction arm 4 and fixed at a certain position on the ground to ensure the stability of the drive motor 2.

[0035] Example 2

[0036] Reference Figure 4-5 The difference between this embodiment and embodiment 1 is that the connector 5 and the rotating seat 6 are connected by multiple fixing bolts 23. Three positioning blocks are fixedly connected to the upper end of the connector 5. The lower end of the rotating seat 6 is provided with multiple positioning grooves that cooperate with the positioning blocks. The outer wall of the rotating seat 6 is provided with multiple through holes 22. Each through hole 22 is provided with an adjusting sleeve 21. Each time it is used, a wrench that cooperates with the adjusting sleeve 21 needs to be prepared in advance.

[0037] In this embodiment, during actual operation, the wrench can be inserted into the adjusting sleeve 21 in sequence. By rotating the wrench, the adjusting sleeve 21 drives the slider to move, thereby adjusting the position of the gripper so that the gripper can better clamp onto the valve, ensuring that the subsequent operation of the drive motor 2 can open or close the valve.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
