[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1-4 As shown, this utility model provides a technical solution:

[0021] A valve maintenance fixture includes a base plate 1, a protective plate 2 fixedly installed on the top of the base plate 1 to enhance the stability of the entire device, and a lubrication assembly provided at the bottom of the protective plate 2 to provide lubrication for the clamping system, reduce friction and wear, and extend the service life of the equipment.

[0022] Furthermore, a cylinder 3 is fixedly installed on the top of the base plate 1 to drive the cleaning component to clean the protective plate 2. The output end of the cylinder 3 is equipped with a cleaning component, which is located on the top of the protective plate 2.

[0023] A motor 4 is fixedly installed on the top of the base plate 1, which drives the rotating shaft 5, further driving the movement of the worm 6 and the worm wheel 7. The output end of the motor 4 is coaxially fixedly connected to the rotating shaft 5, which transmits the power output by the motor 4 to the worm 6. The outer periphery of the rotating shaft 5 is coaxially fixedly connected to the worm 6. A worm wheel 7 is provided on one side of the worm 6, ensuring the smooth transmission of power from the worm 6 to the support rod 8.

[0024] A support rod 8 is coaxially fixedly connected inside the worm gear 7. The support rod 8 is rotatably connected to the top of the base plate 1 via a bearing. The support rod 8 passes through the protective plate 2 and is rotatably connected to it. The worm 6 and the worm gear 7 mesh with each other. A rotating disk 9 is coaxially fixedly connected to the top of the support rod 8. A spiral groove is opened on the top of the rotating disk 9 to guide the movement of multiple fixed blocks 10. Multiple fixed blocks 10 are slidably connected inside the spiral groove. The fixed blocks 10 can fix the valve by moving outward.

[0025] Furthermore, in this embodiment of the present disclosure, the provided lubrication assembly includes a fixed seat 11, a bidirectional screw 12, a threaded block 13, and a clamping block 14. The fixed seat 11 is fixedly installed inside the protective plate 2, and the fixed seat 11 provides a stable support for the entire lubrication assembly. The bidirectional screw 12 is rotatably connected inside the fixed seat 11 through a bearing. The two ends of the bidirectional screw 12 are threadedly connected to the threaded blocks 13. When the bidirectional screw 12 is controlled by the knob 17, the threaded blocks 13 can move in opposite directions along the bidirectional screw 12, thereby driving the clamping block 14 to squeeze the oil box 15 to achieve the purpose of oil discharge. The clamping block 14 is fixedly installed on the side of the threaded block 13 away from the fixed seat 11, and the clamping block 14 is slidably connected to the outer periphery of the bidirectional screw 12.

[0026] Furthermore, the lubrication assembly also includes an oil box 15, an oil outlet pipe 16, and a knob 17. The oil box 15 is fixedly installed at the bottom of the protective plate 2. The oil outlet pipe 16 is fixedly connected to one side of the oil box 15. The oil outlet pipe 16 is close to the outer periphery of the worm gear 7. Two clamping blocks 14 cooperate with the oil box 15. The knob 17 is coaxially fixedly connected to one end of the bidirectional screw 12.

[0027] In one embodiment of this utility model, the cleaning assembly includes a half gear 18, a first connecting rod 19, a cleaning brush 20, and a second connecting rod 22. Two fixed shafts 21 are fixedly installed on the top of the protective plate 2 to ensure that the half gear 18 can rotate smoothly and reduce friction and wear. The half gear 18 is rotatably connected to the outer periphery of the fixed shaft 21 through bearings. The two half gears 18 mesh to form a transmission system, thereby driving the movement of the cleaning brush 20. A second connecting rod 22 is fixedly installed on one side of the half gear 18. The end of the second connecting rod 22 away from the half gear 18 is rotatably connected to the first connecting rod 19, which plays the role of transmitting motion, so that the first connecting rod 19 can move accordingly according to the movement of the second connecting rod 22. A cleaning brush 20 is fixedly installed at the bottom of the first connecting rod 19, which can effectively clean the top surface of the protective plate 2. The bottom of the cleaning brush 20 is provided with bristles, which are close to the top of the protective plate 2.

[0028] When lubrication is required, the double-acting screw 12 is operated by knob 17, causing the threaded block 13 to move along the double-acting screw 12, which in turn drives the clamping block 14 to squeeze the oil box 15. The lubricating oil in the oil box 15 flows to the worm gear 7 and other key components through the oil outlet pipe 16, ensuring that all friction surfaces inside the device receive sufficient lubrication, reducing friction, and extending service life. The cylinder 3 drives the rotation of the half gear 18, and through the transmission of the second connecting rod 22 and the first connecting rod 19, the cleaning brush 20 moves accordingly and cleans the top of the protective plate 2, removing accumulated dust and oil. The bristles of the cleaning brush 20 are in close contact with the protective plate 2 to ensure complete coverage of the cleaning effect and avoid residual dirt from affecting the performance of the equipment.

[0029] Motor 4 drives shaft 5, which in turn drives worm 6 and worm wheel 7 to rotate, causing support rod 8 and rotating disk 9 to rotate. The spiral groove on rotating disk 9 guides multiple fixed blocks 10 to move along the groove. The movement of fixed blocks 10 allows them to precisely clamp the valve, thus completing the clamping task and ensuring that the clamp can be adjusted and precisely fixed as needed.
