Description

Technical Field

[0001] This utility model relates to the field of valve auxiliary opening and closing technology, and specifically discloses a portable adaptive valve auxiliary power opening and closing device. Background Technology

[0002] Valves are key control components in fluid transport systems, possessing functions such as shut-off, regulation, flow guidance, backflow prevention, pressure stabilization, diversion, and overflow / pressure relief. They are widely used in numerous fields including petroleum, chemical, water conservancy, municipal, and fire protection. By altering the flow channel area through the relative movement of the valve core and seat, they achieve flow control of fluid media (such as liquids, gases, and powdered solids). Valves offer advantages such as diverse structures, strong adaptability, high control precision, and long service life. In industrial production and system maintenance scenarios, opening or closing valves according to actual needs is an essential step in ensuring production safety and stable system operation.

[0003] In existing technologies, valve opening and closing operations mostly rely on manual operation by turning the valve handwheel or with the assistance of simple valve wrenches. For small valves, manual operation can meet basic needs, but when dealing with large valves or valves that have become rusted or stuck due to long-term use, manually turning the valve handwheel requires overcoming enormous friction and torque. This is not only time-consuming and laborious, but also inefficient, and may result in incomplete valve opening and closing due to insufficient physical strength of the operator, affecting the operational results.

[0004] Therefore, a portable adaptive valve-assisted power opening and closing device is needed to solve the above problems. Utility Model Content

[0005] This utility model proposes a portable adaptive valve auxiliary power opening and closing device, which can adaptively adapt to valve handwheels of different specifications; and is easy to move; it replaces manual rotation of valve handwheels, effectively saving manpower, improving operating efficiency, and avoiding the problem of valve opening and closing not being completed due to insufficient manpower.

[0006] This utility model is implemented as follows: a portable adaptive valve auxiliary power opening and closing device includes a base and a valve handwheel. A horizontal plate is provided above the base, and a rotating shaft is rotatably connected to the lower end of the horizontal plate. An electric motor with its output end fixedly connected to the rotating shaft is installed at the upper end of the horizontal plate. A connecting plate is fixedly connected to the lower end of the rotating shaft. Two end plates are fixedly connected to the lower end of the connecting plate. A bidirectional lead screw is rotatably connected between the two end plates. Two moving blocks are threaded to the outer wall of the bidirectional lead screw. A clamping block is fixedly connected to the lower end of each of the two moving blocks. A first V-groove is opened on the opposite side of each of the two clamping blocks. A second V-groove is opened on the inner wall of each of the two first V-grooves. A driving mechanism is provided on the left side of the bidirectional lead screw.

[0007] The upper side of the base is provided with a height adjustment mechanism;

[0008] The base has four casters with brakes installed at the four corners of its lower end face, and a pusher is fixedly connected to the upper end of the base.

[0009] As a preferred embodiment of the portable adaptive valve auxiliary power opening and closing device of this utility model, the driving mechanism includes a driving frame fixedly connected to the left end of the left end plate, a worm gear rotatably connected inside the driving frame, a worm wheel meshing with the outer wall of the worm gear, a transmission shaft fixedly connected between the worm wheel and the double-acting screw, and a first handwheel extending to the outside of the driving frame installed at the upper end of the worm gear.

[0010] As a preferred embodiment of the portable adaptive valve auxiliary power opening and closing device of this utility model, the height adjustment mechanism includes a vertical plate fixedly connected to the upper end of the base, a horizontal plate slidably connected to the left end of the vertical plate via a slider and a groove, a fixed plate fixedly connected to the left end of the vertical plate, a lead screw rotatably connected between the fixed plate and the base, the lead screw passing through the horizontal plate and threadedly connected to the horizontal plate, and a second handwheel extending to the top of the fixed plate installed at the upper end of the lead screw.

[0011] As a preferred embodiment of the portable adaptive valve auxiliary power opening and closing device of this utility model, the lower end of the connecting plate is provided with a sliding groove, and the upper ends of the two moving blocks are fixedly connected with sliders that are slidably connected inside the sliding groove.

[0012] As a preferred embodiment of this utility model of a portable adaptive valve auxiliary power opening and closing device, a storage battery is installed at the upper end of the base, and a controller for the operation panel is installed at the right end of the upright plate.

[0013] As a preferred embodiment of the portable adaptive valve auxiliary power opening and closing device of this utility model, the inner walls of both second V-shaped grooves are provided with anti-slip layers.

[0014] As a preferred embodiment of the portable adaptive valve auxiliary power opening and closing device of this utility model, the base has an internal cavity, and a counterweight is provided inside the cavity.

The horizontal plate and its connecting plate, end plate, and clamping blocks below it are lowered by the height adjustment mechanism, allowing the valve handwheel ring to enter between the two clamping blocks. The drive mechanism drives the bidirectional lead screw to rotate, causing the two clamping blocks to move towards each other. The second V-groove can adapt to changes in the diameter and cross-sectional circle size of the valve handwheel ring, ultimately forming a stable four-point support clamp with the handwheel ring through the second V-groove, thereby achieving adaptive clamping for valve handwheels of different specifications.

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0026] Please see Figure 1-4 A portable adaptive valve-assisted power opening and closing device includes a base 1 and a valve handwheel 12. A horizontal plate 2 is provided above the base 1. A rotating shaft 4 is rotatably connected to the lower end of the horizontal plate 2. An electric motor 3 with its output end fixedly connected to the rotating shaft 4 is installed at the upper end of the horizontal plate 2. A connecting plate 5 is fixedly connected to the lower end of the rotating shaft 4. Two end plates 6 are fixedly connected to the lower end of the connecting plate 5. A bidirectional lead screw 7 is rotatably connected between the two end plates 6. Two moving blocks 8 are threadedly connected to the outer wall of the bidirectional lead screw 7. A clamping block 9 is fixedly connected to the lower end of each of the two moving blocks 8. A first V-groove 10 is opened on the opposite side of each of the two clamping blocks 9. A second V-groove 11 is opened on the inner wall of each of the two first V-grooves 10. A drive mechanism is provided on the left side of the bidirectional lead screw 7.

[0027] A height adjustment mechanism is provided on the upper side of the base 1;

[0028] All four corners of the lower end of the base 1 are equipped with casters 22 with brakes, and a push handle 23 is fixedly connected to the upper end of the base 1.

[0029] In this embodiment: When using the device, first push the push handle 23 on the upper end of the base 1, and move the device to the position of the valve handwheel 12 by means of the universal wheels 22 at the four corners of the lower end face of the base 1, so that the two clamping blocks 9 are located above the valve handwheel 12, thereby realizing the convenient movement of the device.

[0030] Next, the height adjustment mechanism drives the horizontal plate 2 to move vertically downward, thereby adjusting the height of the connecting plate 5, end plate 6 and clamping block 9 below the horizontal plate 2, so that the ring of the valve handwheel 12 is located between the two clamping blocks 9.

[0031] Subsequently, the bidirectional lead screw 7 is driven to rotate by the drive mechanism. Since the left and right directions of the bidirectional lead screw 7 are opposite, the rotation of the bidirectional lead screw 7 will drive the two moving blocks 8 to move towards each other, thereby causing the two clamping blocks 9 at the lower end to move closer to each other.

[0032] During the clamping process, because the first V-groove 10 on the opposite side of the clamping block 9 has a V-shaped structure, the second V-groove 11 opened on the inner wall of the first V-groove 10 follows the V-shaped path of the first V-groove 10. The V-shaped structure of the first V-groove 10 allows the second V-groove 11 to adapt to the annulus of valve handwheels 12 with different diameters. The V-shaped structure of the second V-groove 11 itself can further adapt to the size change of the circular cross-section of the valve handwheel 12. Finally, the second V-groove 11 of both clamping blocks 9 forms a four-point support with the valve handwheel 12, stably clamping the valve handwheel 12 and realizing adaptive clamping of valve handwheels 12 of different specifications.

[0033] After clamping is completed, the output end of the electric motor 3 drives the rotating shaft 4 connected to the lower end of the horizontal plate 2 to rotate. The rotating shaft 4 drives the clamped valve handwheel 12 to rotate synchronously through the connecting plate 5 at the lower end, thereby realizing the opening and closing operation of the valve. The rotation angle of the valve handwheel 12 is controlled by the electric motor 3. The electric motor 3 can be selected according to the actual situation to meet the usage requirements, thereby replacing the manual rotation of the valve handwheel 12, effectively saving manpower, improving operating efficiency, and avoiding the problem of valve opening and closing not being in place due to insufficient manpower.

[0034] As a technical optimization of this utility model, the drive mechanism includes a drive frame 13 fixedly connected to the left end of the left end plate 6. A worm 14 is rotatably connected inside the drive frame 13. A worm wheel 15 is meshed with the outer wall of the worm 14. A transmission shaft is fixedly connected between the worm wheel 15 and the bidirectional lead screw 7. A first handwheel extending to the outside of the drive frame 13 is installed at the upper end of the worm 14.

[0035] In this embodiment: rotating the first handwheel drives the worm 14 inside the drive frame 13 to rotate. The worm 14 meshes with the worm wheel 15, causing the worm wheel 15 to drive the bidirectional lead screw 7 to rotate through the transmission shaft. Since the transmission between the worm 14 and the worm wheel 15 has a self-locking characteristic, it prevents the bidirectional lead screw 7 from rotating on its own, thereby improving the stability of clamping the valve handwheel 12.

[0036] As a technical optimization of this utility model, the height adjustment mechanism includes a vertical plate 16 fixedly connected to the upper end of the base 1, a horizontal plate 2 slidably connected to the left end of the vertical plate 16 via a slider and a groove, a fixed plate 17 fixedly connected to the left end of the vertical plate 16, a lead screw 18 rotatably connected between the fixed plate 17 and the base 1, the lead screw 18 passing through the horizontal plate 2 and threadedly connected to the horizontal plate 2, and a second handwheel extending above the fixed plate 17 installed at the upper end of the lead screw 18.

[0037] In this embodiment: rotating the second handwheel causes the lead screw 18 between the fixed plate 17 and the base 1 to rotate. Since the horizontal plate 2 is slidably connected to the left end of the vertical plate 16 through the slider and the slide groove, and the horizontal plate 2 is threadedly connected to the lead screw 18, the rotation of the lead screw 18 will cause the horizontal plate 2 to move vertically downward, thereby adjusting the height of the connecting plate 5, the end plate 6 and the clamping block 9 below the horizontal plate 2, so that the ring of the valve handwheel 12 is located between the two clamping blocks 9.

[0038] As a technical optimization of this utility model, the lower end of the connecting plate 5 is provided with a sliding groove, and the upper ends of the two moving blocks 8 are fixedly connected with sliders that are slidably connected inside the sliding groove.

[0039] In this embodiment: when the bidirectional lead screw 7 rotates, the slider slides along the groove. This structure restricts the moving block 8 to only move in a straight line along the axis of the bidirectional lead screw 7, ensuring that the two moving blocks 8 and the clamping block 9 move synchronously towards or away from each other, thus avoiding deviation.

[0040] As a technical optimization of this utility model, a storage battery 21 is installed at the upper end of the base 1, and a controller 20 of the operation panel 19 is installed at the right end of the upright plate 16.

[0041] In this embodiment: the battery 21 on the base 1 provides power to the electric motor 3, the controller 20 and the operation panel 19. The operator inputs parameters such as the rotation angle through the operation panel 19 and sends control commands to the controller 20. The controller 20 controls the start, stop and direction of the electric motor 3 according to the commands, thereby achieving precise control of the rotation of the valve handwheel 12.

[0042] As a technical optimization of this utility model, the inner walls of the two second V-shaped grooves 11 are provided with anti-slip layers.

[0043] In this embodiment: when the second V-groove 11 contacts the valve handwheel 12, the anti-slip layer on its inner wall increases the friction between it and the valve handwheel 12, preventing relative sliding during clamping and ensuring that the valve handwheel 12 is stably clamped and reliably transmits torque.

[0044] As a technical optimization of this utility model, the base 1 has a cavity inside, and a counterweight 24 is installed inside the cavity.

[0045] In this embodiment, the counterweight 24 inside the cavity of the base 1 improves the stability of the device through the counterweight effect.

[0046] The working principle and usage process of this utility model: When using this device, first push the pusher 23 on the upper end of the base 1, and move the device to the position of the valve handwheel 12 through the universal wheels 22 at the four corners of the lower end face of the base 1, so that the two clamping blocks 9 are located above the valve handwheel 12, thereby realizing the convenient movement of the device.

[0047] Next, rotate the second handwheel in the height adjustment mechanism to drive the lead screw 18 between the fixed plate 17 and the base 1 to rotate. Since the horizontal plate 2 is slidably connected to the left end of the vertical plate 16 through the slider and the slide groove, and the horizontal plate 2 is threadedly connected to the lead screw 18, the rotation of the lead screw 18 will drive the horizontal plate 2 to move vertically downward, thereby adjusting the height of the connecting plate 5, the end plate 6 and the clamping block 9 below the horizontal plate 2, so that the ring of the valve handwheel 12 is located between the two clamping blocks 9.

[0048] Then, the first handwheel in the drive mechanism is turned, which drives the worm 14 inside the drive frame 13 to rotate. The worm 14 meshes with the worm wheel 15, which drives the double-acting screw 7 to rotate through the drive shaft. Since the left and right directions of the double-acting screw 7 are opposite, the rotation of the double-acting screw 7 will drive the two moving blocks 8 to move towards each other, thereby driving the two clamping blocks 9 at the lower end to move closer to each other.

[0049] During the clamping process, because the first V-groove 10 on the opposite side of the clamping block 9 has a V-shaped structure, the second V-groove 11 opened on the inner wall of the first V-groove 10 follows the V-shaped path of the first V-groove 10. The V-shaped structure of the first V-groove 10 allows the second V-groove 11 to adapt to the annulus of valve handwheels 12 with different diameters. The V-shaped structure of the second V-groove 11 itself can further adapt to the size change of the circular cross-section of the valve handwheel 12. Finally, the second V-groove 11 of both clamping blocks 9 forms a four-point support with the valve handwheel 12, stably clamping the valve handwheel 12 and realizing adaptive clamping of valve handwheels 12 of different specifications.

[0050] After clamping is completed, the control panel 19 on the right side of the upright plate 16 sends a command to the controller 20. The battery 21 on the upper part of the base 1 supplies power to the electric motor 3. After the electric motor 3 starts, its output end drives the rotating shaft 4 connected to the lower end of the horizontal plate 2 to rotate. The rotating shaft 4 drives the clamped valve handwheel 12 to rotate synchronously through the connecting plate 5 at the lower end, thereby realizing the opening and closing operation of the valve. The rotation angle of the valve handwheel 12 is controlled by the electric motor 3. The electric motor 3 can be selected according to the actual situation to meet the usage requirements, thereby replacing the manual rotation of the valve handwheel 12, effectively saving manpower, improving operating efficiency, and avoiding the problem of valve opening and closing not being in place due to insufficient manpower.
