Description

Technical Field

[0001] This utility model belongs to the field of valve repair technology, specifically a valve repair fixing device. Background Technology

[0002] Valves are control components in fluid transport systems, with functions such as shutting off, regulating, guiding, preventing backflow, stabilizing pressure, diverting flow, or overflowing and relieving pressure. Valves are basic components in pipeline systems.

[0003] Valves are widely used in alumina production workshops. They are used to control the flow rate and opening and closing of pipelines. Due to prolonged use, valves may malfunction, so valve maintenance is a common part of routine maintenance work.

[0004] Currently, during valve repair, the valve is usually removed and placed on the ground. Repair workers then perform repairs on the valve placed on the ground. However, the valve is heavy and unstable when placed on the ground, and it may tip over during the repair process, potentially injuring the repair workers. This makes the repair process unsafe. Utility Model Content

[0005] To address the problems mentioned above, this utility model provides a valve maintenance and fixing device. When a valve needs to be fixed, the valve is placed above a support plate and between a pair of first threaded rods. After the clamping plate passes through the pre-reserved groove, the first threaded rods are inserted into the pre-reserved holes. Then, the nut is tightened, and the nut presses the clamping plate, which presses the valve onto the support plate, thus fixing the valve to be repaired. Fixing the valve to the support plate by the clamping plate reduces the possibility of the valve tipping over, prevents injury to maintenance personnel, and improves the safety of the maintenance process.

[0006] This utility model provides a valve maintenance and fixing device, including a base, a fixing plate connected to the upper surface of the base, a support plate fixedly connected to the upper surface of the fixing plate, a pair of first threaded rods connected to the upper surface of the support plate, each of the first threaded rods being threaded with a nut, a clamping plate provided above the support plate, the clamping plate having a pair of reserved holes for the first threaded rods to be inserted, the valve being placed on the support plate and having a reserved groove for a connecting plate to pass through.

[0007] By adopting the above technical solution, when it is necessary to fix the valve, the valve is placed above the support plate and between a pair of first threaded rods. After the clamping plate is passed through the reserved groove, the first threaded rods are inserted into the reserved holes. Then, the nut is tightened, the nut presses the clamping plate, and the clamping plate presses the valve onto the support plate, thus fixing the valve that needs to be repaired. Fixing the valve onto the support plate by the clamping plate can reduce the possibility of the valve tipping over, prevent injury to maintenance personnel, and improve the safety of the maintenance process.

[0008] Furthermore, each of the first threaded rods is fixedly connected to a rotating rod at its lower end, and a connecting block is rotatably connected to both ends of the rotating rod. The connecting block is fixedly connected to the upper surface of the support plate, and the reserved hole is provided through the side wall of the pressing plate.

[0009] By adopting the above technical solution, when it is necessary to separate the first threaded rod from the reserved hole, the first threaded rod can be separated from the reserved hole by rotating it to the side away from the pressure plate. When it is necessary to insert the first threaded rod into the reserved hole, the first threaded rod can be inserted into the reserved hole by rotating it to the side closer to the pressure plate. It is not necessary to separate the nut from the first threaded rod, thus improving work efficiency and ease of use.

[0010] Furthermore, a first anti-slip pad is fixedly connected to the upper surface of the support plate and placed below the valve.

[0011] By adopting the above technical solution, the bottom of the valve contacts the first anti-slip pad, increasing the stability of the valve when the clamping plate fixes the valve and reducing the possibility of the valve shifting.

[0012] Furthermore, the support plate has arc-shaped surfaces at each of its four corners.

[0013] By adopting the above technical solution, the arc surface reduces the possibility of workers getting bumped and scratched during maintenance.

[0014] Furthermore, a pair of connecting plates placed on both sides of the valve are fixedly connected to the upper surface of the support plate. Each connecting plate is threaded with a second threaded rod. The end of the second threaded rod near the valve is rotatably connected to a clamping block that abuts against the side of the valve. The end of the second threaded rod away from the clamping block is fixedly connected to a connecting rod. The end of the connecting rod is fixedly connected to a handle.

[0015] By adopting the above technical solution, after the clamping plate clamps the valve, the handle is turned. The handle drives the second threaded rod to rotate through the connecting rod. The second threaded rod drives the clamping block to move closer to the valve, so that the clamping block clamps the valve side. The two clamping blocks clamp and fix the valve side, increasing the stability of the clamping plate when fixing the valve and reducing the possibility of valve displacement.

[0016] Furthermore, the connecting rod is connected to a fixing component for securing the connecting rod.

[0017] By adopting the above technical solution, when the second threaded rod does not need to rotate, the fixing component will fix the rotating rod, reducing the possibility of the second threaded rod rotating and further increasing the stability of the clamping block when pressing the valve.

[0018] Furthermore, the fixing component includes a fixing block that is fixedly connected to the upper surface of the support plate. The fixing block has a fixing hole for inserting the connecting rod, and a fixing bolt that abuts against the connecting rod is threaded to the top of the fixing block.

[0019] By adopting the above technical solution, when it is necessary to fix the connecting rod, the fixing bolt is turned downwards, and the lower end of the fixing bolt is tightly abutted against the connecting rod. The fixing bolt fixes the connecting rod, reducing the possibility of the second threaded rod rotating and increasing the stability of the clamping block when pressing the valve. The fixing bolt is turned upwards to separate the fixing bolt from the connecting rod, thereby releasing the restriction on the connecting rod.

[0020] Furthermore, a second anti-slip pad that contacts the valve is fixedly connected to the side of the clamping block near the valve.

[0021] By adopting the above technical solution, when the clamping block clamps the valve, the second anti-slip pad comes into contact with the valve, and the second anti-slip pad increases the stability of the clamping block when clamping the valve.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0023] (1) When it is necessary to fix the valve, place the valve on the support plate and between a pair of first threaded rods. After passing the clamping plate through the reserved groove, insert the first threaded rod into the reserved hole, and then tighten the nut. The nut presses the clamping plate, and the clamping plate presses the valve on the support plate to fix the valve that needs to be repaired. Fixing the valve on the support plate by clamping the plate can reduce the possibility of the valve tipping over, prevent injury to maintenance personnel, and improve the safety of the maintenance process.

[0024] (2) When it is necessary to separate the first threaded rod from the reserved hole, the first threaded rod can be separated from the reserved hole by rotating it to the side away from the pressure plate. When it is necessary to insert the first threaded rod into the reserved hole, the first threaded rod can be inserted into the reserved hole by rotating it to the side closer to the pressure plate. It is not necessary to separate the nut from the first threaded rod, which improves work efficiency and ease of use.

[0025] (3) The rounded surface reduces the possibility of staff getting scratched or bumped during maintenance. Attached Figure Description

[0031] 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, and 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 protection scope of this utility model.

[0032] The following is in conjunction with the appendix Figure 1 To be continued Figure 3 The present invention will be described in detail with specific embodiments.

[0033] like Figures 1 to 3 As shown, the present invention provides a valve maintenance and fixing device, including a base 1, a fixing plate 11 fixedly connected to the upper surface of the base 1, and a support plate 2 fixedly connected to the upper surface of the fixing plate 11. A pair of first threaded rods 3 are connected to the upper surface of the support plate 2, and each first threaded rod 3 is threadedly connected to a nut 31.

[0034] A clamping plate 4 is provided above the support plate 2. Both sides of the clamping plate 4 are provided with reserved holes 41. The reserved holes 41 are set one-to-one with the first threaded rod 3. The first threaded rod 3 is inserted into the reserved holes 41.

[0035] When valve 5 needs to be fixed, first separate the clamping plate 4 from the first threaded rod 3, place valve 5 above the support plate 2, and position valve 5 between a pair of first threaded rods 3. The outside of valve 5 is provided with a reserved groove 51. After the clamping plate 4 passes through the reserved groove 51, the first threaded rod 3 is inserted into the reserved hole 41. Then tighten the nut 31. The nut 31 presses the clamping plate 4, and the clamping plate 4 presses the valve 5 onto the support plate 2, thereby fixing the valve 5 that needs to be repaired. Compared with the valve 5 being placed on the ground for repair, fixing the valve 5 onto the support plate 2 by the clamping plate 4 can reduce the possibility of the valve 5 tipping over, prevent injury to maintenance personnel, and improve the safety of the maintenance process.

[0036] Each first threaded rod 3 has a rotating rod 32 fixedly connected to its lower end. Each rotating rod 32 has a connecting block 321 rotatably connected to both ends. The connecting block 321 is fixedly connected to the upper surface of the support plate 2. The reserved hole 41 is provided through the side wall of the pressure plate 4. Rotating the first threaded rod 3 away from the pressure plate 4 will separate the first threaded rod 3 from the reserved hole 41. Rotating the first threaded rod 3 towards the pressure plate 4 will insert the first threaded rod 3 into the reserved hole 41.

[0037] During the process of inserting and separating the first threaded rod 3 from the reserved hole 41, it is not necessary to separate the nut 31 from the first threaded rod 3, which improves work efficiency and ease of use.

[0038] A first anti-slip pad 21 is fixedly connected to the upper surface of the support plate 2. When the valve 5 is placed on the support plate 2, the bottom of the valve 5 contacts the first anti-slip pad 21, which increases the stability of the valve 5 when the clamping plate 4 fixes the valve 5 and reduces the possibility of the valve 5 shifting.

[0039] The support plate 2 has rounded surfaces 22 at all four corners, which reduces the possibility of staff getting scratched or bumped during maintenance.

[0040] A pair of connecting plates 6 are fixedly connected to the upper surface of the support plate 2, and the pair of connecting plates 6 are positioned on both sides of the valve 5. Each connecting plate 6 is threaded with a second threaded rod 61, and a clamping block 611 is rotatably connected to the end of each second threaded rod 61 near the valve 5. A connecting rod 612 is fixedly connected to the end of the second threaded rod 61 away from the clamping block 611, and a handle 6121 is fixedly connected to the end of the connecting rod 612 away from the second threaded rod 61.

[0041] After the clamping plate 4 clamps the valve 5, the handle 6121 is rotated. The handle 6121 drives the second threaded rod 61 to rotate through the connecting rod 612. The second threaded rod 61 drives the clamping block 611 to move closer to the valve 5, so that the clamping block 611 clamps the side of the valve 5. The two clamping blocks 611 clamp and fix the side of the valve 5, increasing the stability of the valve 5 when the clamping plate 4 fixes it and reducing the possibility of the valve 5 shifting.

[0042] A second anti-slip pad 6111 is fixedly connected to the side of the clamping block 611 near the valve 5. When the clamping block 611 clamps the valve 5, the second anti-slip pad 6111 comes into contact with the valve 5, and the second anti-slip pad 6111 increases the stability of the clamping block 611 when clamping the valve 5.

[0043] Each connecting rod 612 is connected to a fixing component 7. When the clamping block 611 clamps the valve 5, the fixing component 7 fixes the rotating rod 32, reducing the possibility of the second threaded rod 61 rotating and further increasing the stability of the clamping block 611 when clamping the valve 5.

[0044] Each fixing component 7 includes a fixing block 71 that is fixedly connected to the upper surface of the support plate 2. The fixing block 71 has a fixing hole 711, and the connecting rod 612 is inserted into the fixing hole 711. A fixing bolt 72 is threadedly connected to the top of the fixing block 71, and the lower end of the fixing bolt 72 abuts against the connecting rod 612.

[0045] Tighten the fixing bolt 72 upwards to separate it from the connecting rod 612. As the handle 6121 rotates, driving the second threaded rod 61 through the connecting rod 612, the fixing bolt 72 releases its restriction on the connecting rod 612. When it is necessary to fix the connecting rod 612, tighten the fixing bolt 72 downwards. The lower end of the fixing bolt 72 abuts tightly against the connecting rod 612, fixing the connecting rod 612 and reducing the possibility of the second threaded rod 61 rotating, thus increasing the stability of the valve 5 when the clamping block 611 presses against it.

[0046] The implementation principle of the valve maintenance and fixing device provided by this utility model is as follows: When it is necessary to fix the valve 5, the valve 5 is placed between a pair of first threaded rods 3. After the clamping plate 4 passes through the reserved groove 51, the first threaded rod 3 is rotated to insert into the reserved hole 41. Then, the nut 31 is tightened, and the clamping plate 4 presses the valve 5 onto the support plate 2. The handle 6121 is rotated, and the handle 6121 drives the second threaded rod 61 to rotate through the connecting rod 612. The second threaded rod 61 drives the clamping block 611 to move towards the side closer to the valve 5, so that the clamping block 611 presses the valve 5. The fixing bolt 72 is screwed down, and the fixing bolt 72 fixes the connecting rod 612.

[0047] The present invention has been further described above with reference to specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the substance and scope of the present invention. Various modifications made by those skilled in the art to the above embodiments after reading this specification are all within the scope of protection of the present invention.
