Description

Technical Field

[0001] This utility model belongs to the field of pipe installation technology, and in particular relates to a clamping device for insulated pipes. Background Technology

[0002] During the installation of insulated pipes, clamping is required at different locations. Pipe clamping devices on the market require selection of clamping parts of different sizes according to the pipe dimensions. This can easily lead to installation difficulties when installing pipes of multiple sizes.

[0003] Patent application CN202320941029.4 discloses a clamping device for a high-efficiency insulated pipe, comprising a pipe and a clamping component. The pipe is wrapped with an insulation layer. The clamping component includes a shell, within which a clamping block is provided. The clamping block is connected to the inner wall of the shell via a telescopic device. The clamping block presses against the insulation layer. A base is fixed to the bottom of the shell. By setting the clamping component to fix and limit the pipe wrapped with the insulation layer, and by setting the telescopic device to drive the clamping block to press and fix the outer layer of the insulated pipe, the clamping device does not contact the internal pipe, preventing heat loss from the internal pipe through the clamping device.

[0004] Existing technologies use expansion joints to clamp and fix the outer insulation layer of the pipe, reducing heat loss, but there are still shortcomings:

[0005] First, existing pipe clamping devices require the selection of pipe clamping components in advance based on the pipe size when clamping pipes, and cannot adapt to pipe size for pipe clamping, thus reducing the practicality of the pipe clamping device.

[0006] Secondly, existing pipe clamping components can only clamp pipes in narrow areas, which means that a large number of pipe clamping components need to be installed during pipe laying to ensure the safe operation of the pipes. This results in a waste of clamping components and increases the construction progress of the pipes. Utility Model Content

[0007] To overcome the shortcomings of existing technologies, this invention provides a clamping device for insulated pipes. Through the design of structures such as sliding grooves, this invention allows for adaptive winding and fixing of insulated pipes of different sizes. It also allows for the use of different numbers of first metal strips to meet the clamping requirements of the pipes. Furthermore, through the design of structures such as first sliding rods, the device can clamp and fix multiple parts of a long pipe using a single clamping mechanism.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a clamping device for a thermal insulation pipe, comprising a fixing plate, a support column rotatably disposed on one side of the fixing plate, a first snap-fit ​​frame disposed at one end of the support column on one side of the fixing plate, a snap-fit ​​plate slidably disposed inside the first snap-fit ​​frame, a connecting plate disposed at one end of the snap-fit ​​plate, a sliding groove disposed on one side wall of the connecting plate, a plurality of snap-fit ​​blocks slidably disposed inside the sliding groove, a first metal strip disposed at one end of each snap-fit ​​block, a plurality of first fixing holes disposed on each first metal strip, a plurality of first fixing bolts threadedly disposed on the other side wall of the connecting plate, and each first fixing bolt fixing one end of the corresponding first metal strip through the adjacent first fixing hole.

[0009] Optionally, a rotating ring is provided on the end face of the fixing plate, and a gear is rotatably provided inside the rotating ring. One side wall of the gear is fixedly connected to one end of the support column.

[0010] Optionally, the outer circumference of the rotating ring is provided with an opening, and an elastic snap-fit ​​component is fixedly provided at the port of the opening, the elastic snap-fit ​​component meshing with multiple tooth surfaces of the gear.

[0011] Optionally, an annular groove is provided on the outer circular surface of the support column, and two arc-shaped plates are rotatably arranged on the annular groove. A first sliding rod is rotatably arranged at both ends of the two arc-shaped plates. A second sliding rod is slidably arranged inside each first sliding rod. A rotating connector is rotatably arranged at one end of each second sliding rod. A fixing component is fixedly arranged on one side of each rotating connector.

[0012] Optionally, each of the first and second slide rods has a plurality of second fixing holes on one side wall, and a second fixing bolt is provided inside each pair of adjacent first and second slide rods in the second fixing holes.

[0013] Optionally, the fixing component includes a second metal strip disposed on one side of the rotating connector. The end face of the second metal strip is provided with a plurality of third fixing holes. The two ends of the second metal strip abut against each other to form a ring shape. The two ends of the second metal strip are fixed by third fixing bolts.

[0014] Optionally, a plurality of arc-shaped support blocks are provided on the end face of the connecting plate.

[0015] Optionally, a sealing plate is slidably disposed on one side of the snap-fit ​​plate outside the first snap-fit ​​frame.

[0016] Optionally, anti-slip plates are provided on both sides of the groove on the side wall of the connecting plate.

[0017] In summary, compared with existing technologies, the beneficial effects of this solution are as follows:

[0018] (1) By setting up the sliding groove, the snap-fit ​​block and the first metal strip, the device can use the first metal strip to adaptably wrap the pipe and fix it when clamping the insulated pipe of different sizes. Different numbers of first metal strips can be set according to the clamping and fixing requirements of the pipe, so as to achieve the required clamping and fixing strength of the pipe. When the first metal strip is damaged, the individual first metal strip can be directly replaced, which effectively improves the practicality of the device.

[0019] (2) By setting up the first sliding rod, the second sliding rod, and the second metal strip, the present invention enables the device to clamp and fix multiple parts of a long pipe through a clamping device, effectively reducing the number of clamping devices used during pipe laying, improving construction efficiency and reducing construction costs.

[0020] (3) By setting up structures such as rotating rings, gears and elastic snap-fit ​​parts, the fixed plate can be pre-fixed according to the installation position of the pipeline. During subsequent pipeline installation, the angle can be finely adjusted according to the actual pipeline laying route, thereby effectively improving the convenience of construction and further increasing construction efficiency.

Detailed Implementation

[0028] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0029] Example 1:

[0030] like Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, a clamping device for a thermal insulation pipe includes a fixing plate 10. A support column 15 is rotatably mounted on one side of the fixing plate 10. A first snap-fit ​​frame 16 is mounted on one end of the support column 15 on one side of the fixing plate 10. A snap-fit ​​plate 17 is slidably mounted inside the first snap-fit ​​frame 16. A connecting plate 19 is mounted on one end of the snap-fit ​​plate 17. A sliding groove 20 is mounted on one side wall of the connecting plate 19. Multiple snap-fit ​​blocks 21 are slidably mounted inside the sliding groove 20. A first metal strip 22 is mounted on one end of each snap-fit ​​block 21. Multiple first fixing holes 23 are mounted on each first metal strip 22. Multiple first fixing bolts 24 are threadedly mounted on the other side wall of the connecting plate 19. Each first fixing bolt 24 fixes one end of the corresponding first metal strip 22 through the adjacent first fixing hole 23.

[0031] Specifically, the second metal strip 32 is made of flexible high-strength metal, such as aluminum alloy, and can be bent to adapt to different sizes of insulated pipes. The first metal strip 22 is fixed by the first fixing bolt 24 on one side of the connecting plate 19 through the corresponding first fixing hole 23, thereby fixing the pipe to one side of the connecting plate 19.

[0032] The first metal strip 22 slides inside the groove 20 via a snap-fit ​​block 21 at one end, making it easy to disassemble and install. This allows for the installation of different numbers of strips according to actual needs, and also enables timely replacement of some of the first metal strips 22 when they corrode and break after long-term use.

[0033] The first snap-fit ​​frame 16 has a sliding groove inside, and one end of the snap-fit ​​plate 17 has a slider. The snap-fit ​​plate 17 is slidably installed inside the first snap-fit ​​frame 16 through the slider at one end, so that the connecting plate 19, which is fixedly connected to the snap-fit ​​plate 17, can be quickly disassembled and installed with the support column 15 and the first snap-fit ​​frame 16. This facilitates the installation and disassembly of the entire device and also allows the device to make multiple choices according to the actual pipeline installation: the pipeline can be installed on one side of the connecting plate 19 first, and then the snap-fit ​​plate 17, the connecting plate 19, and the pipeline can be installed on one side of the first snap-fit ​​frame 16; or the snap-fit ​​plate 17 can be installed inside the first snap-fit ​​frame 16 first, and then the pipeline can be installed on one side of the connecting plate 19. This makes the clamping and installation of the pipeline more versatile and improves the diversity of pipeline construction.

[0034] Furthermore, such as Figure 1 and Figure 3 As shown, an annular groove 35 is provided on the outer circular surface of the support column 15. Two arc-shaped plates 27 are rotatably arranged on the annular groove 35. A first slide rod 28 is rotatably arranged at both ends of the two arc-shaped plates 27. A second slide rod 29 is slidably arranged inside each first slide rod 28. A rotating connector 36 is rotatably arranged at one end of each second slide rod 29. A fixing component is fixedly arranged on one side of each rotating connector 36.

[0035] Specifically, by rotating two arc-shaped plates 27 inside the annular groove 35, components such as the first slide rod 28 and the second slide rod 29 can be rotated, making it more convenient for the device to clamp and fix the cross-shaped pipe interface. At the same time, components such as the first slide rod 28 and the second slide rod 29 can be rotated, and the combined length of the first slide rod 28 and the second slide rod 29 can be adjusted so that the fixing components can further fix the pipe. This increases the device's ability to clamp the pipe while reducing the number of clamping devices for the same pipe length.

[0036] Furthermore, such as Figure 3 As shown, each of the first slide rods 28 and the second slide rods 29 has a plurality of second fixing holes 30 on one side wall, and a second fixing bolt 31 is provided inside each pair of adjacent first slide rods 28 and second slide rods 29 in the second fixing holes 30.

[0037] Specifically, by setting multiple second fixing holes 30 and second fixing bolts 31, it is possible to fix the first slide bar 28 and the second slide bar 29 after the joint length is adjusted, so as to avoid the change in the joint length of the first slide bar 28 and the second slide bar 29, which would affect the clamping position of the fixing component.

[0038] Furthermore, such as Figure 3As shown, the fixing component includes a second metal strip 32 disposed on one side of the rotating connector 36. A plurality of third fixing holes 33 are provided on the end face of the second metal strip 32. The two ends of the second metal strip 32 abut against each other to form a ring shape. The two ends of the second metal strip 32 are fixed by third fixing bolts 34.

[0039] Specifically, the second metal strip 32 is also made of flexible high-strength metal. For pipes of different sizes, the two ends of the second metal strip 32 can be pulled to form a ring clamp on the pipe. Then, the third fixing bolt 34 is used to fix the two ends of the second metal strip 32 through the multiple third fixing holes 33 provided at both ends of the second metal strip 32, thereby forming a clamp on the pipe.

[0040] Furthermore, such as Figure 1 , Figure 4 and Figure 5 As shown, a rotating ring 11 is provided on the end face of the fixed plate 10. A gear 12 is rotatably provided inside the rotating ring 11. One side wall of the gear 12 is fixedly connected to one end of the support column 15. An opening 13 is provided on the outer circular surface of the rotating ring 11. An elastic snap-fit ​​member 14 is fixedly provided at the port of the opening 13. The elastic snap-fit ​​member 14 is meshed with multiple tooth surfaces of the gear 12.

[0041] Specifically, the teeth on gear 12 can pass through opening 13 and be exposed to the outside of rotating ring 11. The elastic locking member 14 is made of elastic metal material and has multiple grooves. The teeth on gear 12 mesh with the grooves on elastic locking member 14. When gear 12 rotates, the teeth on gear 12 will squeeze elastic locking member 14. Only when the rotational pressure of 12 is large will elastic locking member 14 be forced to deform, so that without the action of a large external force, elastic locking member 14 can fix gear 12 and prevent gear 12 from rotating.

[0042] Furthermore, such as Figure 1 As shown, a sealing plate 18 is slidably disposed on one side of the snap-fit ​​plate 17 outside the first snap-fit ​​frame 16.

[0043] Specifically, the sealing plate 18 can fix one end of the snap-fit ​​plate 17, so that the slider at one end of the snap-fit ​​plate 17 can be fixed inside the groove inside the first snap-fit ​​frame 16, thereby fixing the sealing plate 18 and the connecting plate 19 and other components.

[0044] Furthermore, such as Figure 1 As shown, multiple arc-shaped support blocks 25 are provided on the end face of the connecting plate 19.

[0045] Specifically, the arc-shaped support block 25 is made of elastic material. Multiple arc-shaped support blocks 25 can form a support for the pipe clamping on the upper end face of the connecting plate 19. At the same time, they can also prevent the pipe from being severely squeezed and deformed by their own elastic deformation when clamping and fixing the pipe.

[0046] Furthermore, such as Figure 1 As shown, anti-slip plates 26 are provided on both sides of the slide 20 on the side wall of the connecting plate 19.

[0047] Specifically, by setting the anti-slip plate 26, a seal can be formed at both ends of the slide groove 20, effectively preventing multiple snap-fit ​​blocks 21 from coming out of the interior of the slide groove 20.

[0048] First, install the fixing plate 10 on the wall near the preset position of the pipe. Then, place the pipe on the arc surface of multiple arc-shaped support blocks 25 and pull one end of multiple first metal strips 22 so that the multiple first metal strips 22 form a surrounding clamp on the pipe. Next, fix one end of the first metal strip 22 to one side of the connecting plate 19 through the first fixing bolt 24 and the first fixing hole 23. Then, install the end of the snap-fit ​​plate 17 with the protrusion inside the groove of the first snap-fit ​​frame 16. At this time, the pipe and the connecting plate 19 and other components are installed on one side of the first snap-fit ​​frame 16 along with the snap-fit ​​plate 17. Then, adjust the horizontal angle of the pipe according to the actual needs. Alternatively, the support column 15 can be rotated before the snap-fit ​​plate 17 is installed inside the first snap-fit ​​frame 16 to adjust the horizontal angle of the pipe after installation.

[0049] Then, rotate multiple arc plates 27 so that the components such as the first slide rod 28 are on the same plane as the pipe. Then rotate the first slide rod 28 so that one end of the second metal strip 32 fits tightly against one side of the pipe. During the above process, the joint length of the first slide rod 28 and the second slide rod 29 can be adjusted according to the actual construction requirements. The joint length of the first slide rod 28 and the second slide rod 29 is fixed by passing the second fixing bolt 31 through the corresponding second fixing hole 30.

[0050] Finally, pull both ends of the second metal strip 32 to form a ring clamp on the pipe. Then, use the third fixing bolt 34 to pass through the third fixing hole 33 at both ends of the second metal strip 32 to fix both ends of the second metal strip 32, thereby further clamping and fixing the pipe with the second metal strip 32.
