[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1-8 , in the figure, there is a flowmeter hoist, which includes a base 1. Above the base 1, there are two groups of support frames 2. The support frames 2 are connected to the base 1 through a lifting mechanism. The support frames 2 are designed in a semi-circular ring shape. On one side of the support frame 2, a fixed plate 12 is fixedly installed. On the side of the fixed plate 12 away from the support frame 2, a support plate 11 is fixedly installed. Between the two groups of support frames 2, there are three groups of limit plates 3. The limit plates 3 are connected to the support frames 2 through an adjustment mechanism. On both sides of the two groups of support frames 2 away from each other, there are mounting frames 19. The mounting frames 19 are slidably connected to the support plate 11. On the side of the mounting frame 19 close to the limit plate 3, there are two groups of movable clamps 22.

[0021] The lifting mechanism includes two groups of fixed frames 13. The fixed frames 13 are fixedly installed above the base 1. Inside the fixed frames 13, sliders 14 are slidably installed. Inside one of the sliders 14, a driving structure is provided. On the side of the slider 14 close to the support plate 11, a fixed rod 17 is fixedly installed. An adjusting block 18 is movably sleeved outside the fixed rod 17. The adjusting block 18 is fixedly connected to the support plate 11.

[0022] The driving structure includes a threaded rod 15. The threaded rod 15 is rotatably inserted inside the fixed frame 13. Above the threaded rod 15, a motor 16 is fixedly installed. The motor 16 is fixedly connected to the fixed frame 13.

[0023] Specifically, the flowmeter is placed inside the two groups of support frames 2. The adjustment mechanism drives the three groups of limit plates 3 to approach each other. The limit plates 3 adjust the position of the flowmeter, making the axis of the flowmeter parallel to the central axis of the support plate 11. Under the action of the base 1, the motor 16 is connected to an external power source. Under the action of the fixed frame 13, the motor 16 drives the threaded rod 15 to rotate. Since the threaded rod 15 is threadedly connected to the slider 14, the threaded rod 15 can drive the slider 14 to lift inside the fixed frame 13. The support plate 11 is connected to the slider 14 through the adjusting block 18 and the fixed rod 17. Therefore, the slider 14 can drive the support plate 11 to move synchronously, lifting the flowmeter to an appropriate height, and then moving the base 1 towards the direction of the installation pipeline, so that the installation pipeline is located between the two groups of clamps 22.

[0024] The adjustment mechanism includes an adjustment member 7. The adjustment member 7 is rotatably installed on the side of the support frame 2 away from the limit plate 3 through a rotation structure. A power assembly is provided outside the adjustment member 7. A chute 6 is opened on the edge of the support frame 2. A guide groove 8 is opened on the edge of the adjustment member 7. A rod member 5 is slidably inserted together inside the chute 6 and the guide groove 8. At one end of the rod member 5 close to the limit plate 3, a push block 4 is fixedly installed. The push block 4 is fixedly connected to the limit plate 3.

[0025] The rotating structure includes an installation groove 9 and an installation seat 10. The installation groove 9 is opened on one side of the support frame 2 close to the adjusting member 7, and the installation seat 10 is fixedly installed outside the adjusting member 7. The installation groove 9 and the installation seat 10 are rotatably connected.

[0026] The power assembly includes a cross plate 33. The cross plate 33 slidably penetrates through the support plate 11. A moving structure is arranged outside the cross plate 33. One end of the cross plate 33 close to the adjusting member 7 is rotatably installed with an adjusting plate 34. One end of the adjusting plate 34 away from the cross plate 33 is rotatably installed with a shaft member 35. The shaft member 35 is fixedly connected to the edge of the adjusting member 7.

[0027] The moving structure includes an installation plate 28 and an electric push rod 30. The electric push rod 30 is fixedly installed on one side of the support plate 11. The output end of the electric push rod 30 penetrates through the support plate 11. The installation plate 28 is fixedly installed at the output end of the electric push rod 30. The installation plate 28 and the cross plate 33 are fixedly connected.

[0028] Further, connect the electric push rod 30 to an external power source. Under the action of the support plate 11, the electric push rod 30 drives the installation plate 28 to move towards the support plate 11. The installation plate 28 drives the cross plate 33 to move synchronously. The cross plate 33 pushes the adjusting plate 34 to rotate. Since the adjusting plate 34 is connected to the adjusting member 7 through the shaft member 35, and the adjusting member 7 is rotatably connected to the support frame 2 through the installation groove 9 and the installation seat 10, the adjusting plate 34 can push the adjusting member 7 to rotate. Under the action of the guide groove 8, the rod member 5 slides inside the sliding groove 6. The rod member 5 drives the limiting plate 3 to move through the push block 4, and the three limiting plates 3 approach each other.

[0029] An activity groove 20 is opened inside the installation frame 19. An activity block 21 is slidably installed inside the activity groove 20. The activity block 21 is fixedly connected to the fixture 22. The activity block 21 is connected to the installation plate 28 through a sliding component.

[0030] The sliding component includes a rotatable rotating shaft 23. The rotating shaft 23 is rotatably installed on one side of the installation frame 19. A gear 24 is fixedly sleeved outside the rotating shaft 23. One-way racks 25 are fixedly installed on both adjacent sides of the two activity blocks 21. The one-way racks 25 are engaged with the gear 24.

[0031] A second rack 26 is arranged outside the gear 24. A moving block 27 is fixedly installed on one side of the second rack 26. The moving block 27 is slidably connected to the support plate 11. A push plate 29 is rotatably installed on the side of the moving block 27 away from the second rack 26. The side of the push plate 29 away from the moving block 27 is rotatably connected to the installation plate 28. A cross bar 31 is fixedly installed outside the support plate 11. The cross bar 31 is slidably connected to the installation frame 19. A spring 32 is movably sleeved outside the cross bar 31. The spring 32 is fixedly connected to the installation frame 19.

[0032] Furthermore, when the mounting plate 28 moves, it can drive the push plate 29 to rotate. The push plate 29 drives the moving block 27 to move. Since the gear 24 meshes with the second rack 26, when the moving block 27 moves, it can drive the gear 24 and the rotating shaft 23 to rotate. Since the gear 24 meshes with the first rack 25, when the gear 24 rotates, it can drive the first rack 25 to move. The first rack 25 drives the movable block 21 to slide inside the movable groove 20, thereby providing driving force for the movement of the clamp 22. During the process of the clamp 22 clamping the installation pipeline, the height of the support plate 11 can be adjusted so that the axis of the installation pipeline coincides with the axis of the flowmeter.

[0033] Furthermore, when the gear 24 stops rotating or when the moving block 27 contacts the mounting bracket 19, the moving block 27 can drive the mounting bracket 19 to move synchronously. At this time, the mounting bracket 19 slides outside the cross bar 31, and the spring 32 deforms under force, facilitating the clamping of installation pipelines of different sizes.

[0034] Working principle: The flowmeter is placed inside the two sets of support frames 2. The adjusting mechanism drives the three sets of limit plates 3 to approach each other. The limit plates 3 adjust the position of the flowmeter so that the axis of the flowmeter is parallel to the central axis of the support plate 11. Under the action of the base 1, the motor 16 is connected to an external power source. Under the action of the fixing frame 13, the motor 16 drives the threaded rod 15 to rotate. Since the threaded rod 15 is threadedly connected to the slider 14, the threaded rod 15 can drive the slider 14 to lift inside the fixing frame 13. The support plate 11 is connected to the slider 14 through the adjusting block 18 and the fixing rod 17. Therefore, the slider 14 can drive the support plate 11 to move synchronously, lifting the flowmeter to an appropriate height. Then, the base 1 is moved towards the installation pipeline so that the installation pipeline is located between the two sets of clamps 22.

[0035] Connect the electric push rod 30 to an external power source. Under the action of the support plate 11, the electric push rod 30 drives the mounting plate 28 to move towards the support plate 11. The mounting plate 28 drives the cross plate 33 to move synchronously. The cross plate 33 pushes the adjusting plate 34 to rotate. Since the adjusting plate 34 is connected to the adjusting member 7 through the shaft member 35, and the adjusting member 7 is rotationally connected to the support frame 2 through the mounting groove 9 and the mounting seat 10, the adjusting plate 34 can drive the adjusting member 7 to rotate. Under the action of the guide groove 8, the rod member 5 slides inside the sliding groove 6. The rod member 5 drives the limit plate 3 to move through the push block 4, and the three sets of limit plates 3 approach each other.

[0036] When the mounting plate 28 moves, it can drive the push plate 29 to rotate. The push plate 29 drives the moving block 27 to move. Since the gear 24 meshes with the second rack 26, when the moving block 27 moves, it can drive the gear 24 and the rotating shaft 23 to rotate. Since the gear 24 meshes with the first rack 25, when the gear 24 rotates, it can drive the first rack 25 to move. The first rack 25 drives the movable block 21 to slide inside the movable groove 20, thereby providing driving force for the movement of the clamp 22. When the gear 24 stops rotating, or when the moving block 27 contacts the mounting frame 19, the moving block 27 can drive the mounting frame 19 to move synchronously. At this time, the mounting frame 19 slides outside the cross bar 31, and the spring 32 deforms under force, facilitating the clamping of installation pipes of different sizes. During the process of the clamp 22 clamping the installation pipe, the height of the support plate 11 can be adjusted so that the axis of the installation pipe coincides with the axis of the flowmeter.
