Description

Technical Field

[0001] The utility model relates to the technical field of valve maintenance, in particular to a fixing mechanism for valve maintenance. Background Art

[0002] The valve is a control component in the fluid delivery system, with functions such as shutoff, regulation, diversion, backflow prevention, pressure stabilization, diversion or overflow pressure relief. When the valve body fails and needs to be repaired, the valve body needs to be fixed to ensure that the valve does not move during the maintenance process to ensure the safety and accuracy of the maintenance work. The fixing mechanism can help maintenance personnel stabilize the valve for disassembly, cleaning, inspection, replacement of parts or other necessary maintenance operations.

[0003] The existing valve maintenance and fixing method is to fix the valve by vise, clamp or strap. On the one hand, when clamping the valve, the clamping position of the valve can only be ensured by adjusting the valve body to ensure the stability of the clamping, which is time-consuming and laborious. On the other hand, after the valve is fixed, the placement angle of the valve cannot be adjusted, that is, it is impossible to provide maintenance personnel with different angles of the valve, which is not conducive to maintenance personnel to repair the valve. Utility Model Content

[0004] The main purpose of the utility model is to provide a fixing mechanism for valve maintenance, which can effectively solve the technical problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] As a further solution of the utility model, a second motor is installed on the base, a gear is installed on the output shaft of the second motor, a limiting plate is fixedly installed on the bottom end of the placement plate, a sliding groove is opened on the limiting plate, and the sliding groove and the pawl are elastically connected by a spring.

[0008] As a further solution of the utility model, the outer ring and the inner ring of the adjustment ring are respectively provided with a gear ring and a ratchet, the gear ring is meshingly connected with the gear, and the ratchet is matched with the pawl.

[0010] As a further solution of the present utility model, a plurality of slots are formed in the clamping bar, clamping plates are inserted into the slots, and a rubber plate is arranged on one side of the clamping plate close to the placing disk.

[0011] As a further solution of the present utility model, the slots are arranged in an array, and the cross section of the slot is an "L" shaped structure.

[0012] The beneficial effects of the present utility model are as follows:

[0013] By providing the rotating disk, the clamping assembly, the placing disk, and the adjusting ring, it is only necessary to place the valve on the placing disk, and then the clamping angle of the valve can be adjusted according to requirements, ensuring the clamping stability, which is time-saving and labor-saving;

Specific implementation manner

[0021] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific implementation manners.

[0022] As Figures 1-4 shown, a fixing mechanism for valve maintenance includes a base 1, a rotating disk 2 is rotatably installed on the base 1, a clamping assembly 3 is arranged at the top end of the rotating disk 2, and the rotating disk 2 can drive the clamping assembly 3 to rotate. Without moving the valve body, different positions of the valve can be selected for clamping, improving applicability. A placing disk 4 is rotatably installed inside the rotating disk 2 for placing the valve body to be repaired. An adjusting ring 5 is fixedly installed at the bottom end of the rotating disk 2, a motor II 7 is installed on the base 1, and a gear 6 is installed on the output shaft of the motor II 7 for controlling the rotation angle of the rotating disk 2. A limiting disk 8 is fixedly installed at the bottom end of the placing disk 4, a sliding groove 9 is opened on the limiting disk 8, and a pawl 10 is elastically connected in the sliding groove 9 through a spring. The contact surface between the sliding groove 9 and the pawl 10 is a "T" - shaped structure, playing a limiting role, and the pawl 10 slides more stably along the sliding groove 9. Through the pawl 10 and the adjusting ring 5, it can be controlled whether the rotating disk 2 and the placing disk 4 rotate synchronously. Rotating separately is used to adjust the position of the clamping assembly 3, so that the fixed position of the valve can be adjusted. Synchronous rotation is used to adjust the maintenance angle of the valve after the valve is fixed, facilitating maintenance.

[0023] In this embodiment, a gear ring 51 and a ratchet wheel 52 are respectively arranged on the outer ring and the inner ring of the adjusting ring 5. The gear ring 51 is meshed with the gear 6, and the rotation of the gear ring 51 can be controlled, thereby controlling the rotation of the adjusting ring 5. The rotation angle and direction are adjustable, so as to control the rotation direction and angle of the rotating disk 2. The ratchet wheel 52 is adapted to the pawl 10. When the ratchet wheel 52 rotates forward, it will squeeze the pawl 10, causing the pawl 10 to disengage from the ratchet wheel 52, without affecting the operation of the ratchet wheel 52. When the ratchet wheel 52 rotates backward, the ratchet wheel 52 squeezes the pawl 10, driving the pawl 10 to rotate synchronously. The pawl 10 drives the limiting disk 8 to rotate, thereby driving the placing disk 4 to rotate, so that after the valve is fixed, the placing angle of the valve can still be adjusted.

[0024] In this embodiment, the clamping assembly 3 includes two mounting brackets 31, both of which are fixedly mounted on the top end of the rotating disc 2 and are symmetrically arranged along a diameter of the rotating disc 2. A limiting rod 32 and a bidirectional lead screw 33 are respectively rotatably mounted in the two mounting brackets 31. One end of the bidirectional lead screw 33 is fixedly connected to a first motor 34, and the first motor 34 is mounted inside the mounting bracket 31 and can rotate following the mounting bracket 31. A clamping strip 35 is mounted between the limiting rod 32 and the bidirectional lead screw 33. There are two clamping strips 35, both of which are threadedly connected to the bidirectional lead screw 33. By rotating the bidirectional lead screw 33, the relative or opposite displacement of the clamping strips 35 can be controlled. The clamping strip 35 is slidably connected to the limiting rod 32, making the displacement of the clamping strip 35 more stable.

[0025] In this embodiment, a plurality of slots 36 are formed in the clamping strip 35, and clamping plates 37 are inserted into the slots 36, which facilitates the quick installation and replacement of the clamping plates 37, thereby changing the clamping area to adapt to different types of valves and the clamping of different positions of the valves, improving the clamping stability. And the quick disassembly and assembly of multiple clamping plates 37 enables the quick replacement of a single clamping plate 37 when it is damaged, with lower cost and without affecting the fixing work, effectively improving the convenience of later maintenance and operation. A rubber plate 38 is arranged on the side of the clamping plate 37 close to the placing disc 4 for elastic contact with the valve, which improves the clamping force while avoiding damaging the valve.

[0026] In this embodiment, the slots 36 are arranged in an array, and the cross-section of the slots 36 is an "L"-shaped structure, making the insertion of the clamping plates 37 into the slots 36 more stable and providing support for one side of the clamping plates 37, and being more stable during clamping.

[0027] It should be noted that the present utility model is a fixing mechanism for valve maintenance. When in use, the valve body to be repaired is placed at the center of the placing disc 4, the second motor 7 is started, the second motor 7 drives the gear 6 to rotate, and drives the adjusting ring 5 to rotate through the meshing of the gear 6 and the toothed ring 51, thereby driving the rotating disc 2 to rotate. The rotation of the rotating disc 2 drives the clamping assembly 3 to rotate, and the clamping angle can be adjusted to ensure the clamping stability. By adjusting the number of the clamping plates 37 on the clamping strip 35, different valves and different clamping positions of the valves can be adapted. The second motor 7 is turned off, and the first motor 34 is started. The first motor 34 drives the bidirectional lead screw 33 to rotate, thereby driving the clamping plates 37 to move towards each other to clamp the valve body.

[0028] By the reverse rotation of the second motor 7, the adjusting ring 5 can be driven to rotate in the reverse direction, thereby driving the ratchet wheel 52 to rotate in the reverse direction. The ratchet wheel 52 is engaged with the pawl 10, so that the adjusting ring 5 can drive the limiting disc 8 to rotate, and the limiting disc 8 drives the placing disc 4 to rotate, thereby driving the valve body to rotate, facilitating the multi-angle repair of the valve and improving the convenience of valve repair.
