Description

Technical Field

[0001] This utility model belongs to the field of pipeline transportation fixing technology, and in particular relates to a thermal insulation pipeline bearing device. Background Technology

[0002] Insulated pipes are widely used in centralized heating, cooling, and hot oil transportation, as well as in insulation and cold preservation projects in industries such as greenhouses, cold storage, coal mines, petroleum, and chemicals. When transporting insulated pipes, and provided that regulations are met, multiple insulated pipes need to be stacked in layers to increase the number of pipes that can be transported at one time.

[0003] Patent application CN202320718640.0 discloses a thermal insulation pipe carrying device, which includes a limiting member disposed between two adjacent thermal insulation pipes on the same layer, a first connecting member detachably connected to the limiting member, and a second connecting member detachably connected to the limiting member. The first connecting member and the second connecting member are respectively used to connect two adjacent thermal insulation pipes located on the upper layer so that the two adjacent thermal insulation pipes on the upper layer abut each other, and the two adjacent thermal insulation pipes on the upper and lower layers abut each other. This application reduces the overall height of two adjacent thermal insulation pipes stacked together, reducing the possibility of vehicles transporting thermal insulation pipes exceeding the height limit. In addition, the two adjacent thermal insulation pipes on the upper layer are connected together by the limiting member, the first connecting member, and the second connecting member to increase the stability of the thermal insulation pipes loaded on the vehicle, reducing the need for reloading of the thermal insulation pipes if they roll off.

[0004] Existing technologies increase the stability of insulated pipelines during transportation by using structures such as limiting components, but there are still shortcomings:

[0005] Firstly, when existing insulated pipe bearing devices limit and fix multiple pipes, they only clamp the adjacent pipe walls between two pipes, thus making multiple pipes closely adjacent. However, when transporting large-sized and numerous pipes, the stacking of multiple pipes can easily cause compression between the pipes, resulting in some pipes being squeezed and deformed, thus affecting the overall quality of the pipes after transportation.

[0006] Secondly, when the existing bearing device clamps the pipe, the multiple bearing device supports lack connection and fixation. Therefore, when bumps occur during transportation, the pipes are more likely to squeeze and collide with each other, thus affecting the overall transportation effect. Utility Model Content

[0007] To overcome the shortcomings of existing technologies, this invention provides a support device for insulated pipes. By incorporating structures such as support slides, multiple arc-shaped support plates can form a support for the inner wall of the insulated pipe, thereby improving the overall strength of the pipe. Furthermore, by using structures such as annular snap-fit ​​grooves and controlling the length between the second and first snap-fit ​​balls, the tightness of the fixation between multiple pipes can be controlled.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a thermal insulation pipe support device, comprising multiple thermal insulation pipes, each of which has a circular plate inside, and multiple telescopic snap-fit ​​components on the outer circular surface of each circular plate, each of which has an arc-shaped support plate at its output end, and an annular snap-fit ​​groove on one side wall of each circular plate, and a bidirectional internal threaded sleeve between every two adjacent circular plates, with a first snap-fit ​​ball slidably disposed at one end of each bidirectional internal threaded sleeve, and a second snap-fit ​​ball slidably disposed at the other end of each bidirectional internal threaded sleeve, and each first snap-fit ​​ball and second snap-fit ​​ball being slidably snap-fitted and connected to its adjacent annular snap-fit ​​groove.

[0009] Multiple arc-shaped support plates provide support for the inner circular surface of the insulated pipes, preventing them from being squeezed and deformed during transportation.

[0010] Optionally, the telescopic snap-fit ​​assembly includes an elongated plate disposed on the outer circular surface of the circular plate. A first sliding groove is provided on one side wall of the elongated plate, and a supporting sliding plate is slidably disposed inside the first sliding groove. Each supporting sliding plate is fixedly connected to one side wall of its adjacent arc-shaped support plate. A second sliding groove is provided on both opposite side walls inside the first sliding groove. Multiple one-way teeth are slidably disposed inside each second sliding groove, and one end of each one-way tooth is fixedly connected to the side wall of its adjacent supporting sliding plate.

[0011] Optionally, the telescopic snap-fit ​​assembly further includes an elongated hole disposed on the inner sidewall of the second slide groove. A rotating rod is rotatably disposed inside each elongated hole, and a snap-fit ​​protrusion is disposed at one end of each rotating rod. Each snap-fit ​​protrusion engages with multiple adjacent one-way teeth.

[0012] By rotating the rotating rod and the locking protrusion at one end of the rotating rod, multiple one-way teeth are locked together, which restricts the sliding of the support slide plate inside the first slide groove, thereby restricting the position of multiple arc-shaped support plates.

[0013] Optionally, each of the rotating rods is connected to an elastic flap between itself and its adjacent long plate.

[0014] The elastic flaps provide support for one end of the rotating rod, facilitating the repositioning of the insulated pipe installed at that end of the rotating rod.

[0015] Optionally, one end of each of the bidirectional internal threaded sleeves is threadedly connected to a first threaded rod, one end of each first threaded rod is connected to a first connecting block, one side wall of each first connecting block is fixedly connected to its adjacent first snap-fit ​​ball, and the other end of each of the bidirectional internal threaded sleeves is threadedly connected to a second threaded rod, one end of each second threaded rod is provided with a second connecting block, one side wall of each second connecting block is fixedly connected to its adjacent second snap-fit ​​ball.

[0016] Optionally, a support rod is provided between each pair of connected support slides and arc-shaped support plates.

[0017] By setting up support rods, support is formed between the support plate and the arc-shaped support plate, making the arc-shaped support plate more stable when supporting the inner wall of the insulated pipe.

[0018] Optionally, each of the arc-shaped support plates is provided with an anti-slip pad on its arc-shaped end face.

[0019] The anti-slip pads effectively protect the inner wall of the pipe, preventing the curved support plate from bumping or hitting the inner wall of the insulated pipe when supporting it, and also making the curved support plate more secure when supporting the inner wall of the insulated pipe.

[0020] Optionally, each of the annular snap-fit ​​grooves has an installation groove on one side wall of the circular plate, each installation groove is interconnected with its adjacent annular snap-fit ​​groove, and each installation groove has a detachable limiting plate inside.

[0021] The annular snap-fit ​​groove design ensures that the first or second snap-fit ​​ball entering the annular snap-fit ​​groove will not detach from the groove, thereby improving the stability of the device.

[0022] In summary, compared with existing technologies, the beneficial effects of this solution are as follows:

[0023] (1) By setting up structures such as a support plate, an arc support plate and a long plate, this utility model enables multiple arc support plates to support the inner wall of the insulated pipe, thereby improving the overall strength of the pipe. As a result, when multiple pipes are transported together, the mutual squeezing between the pipes will not cause the pipes to deform or break, thereby improving the overall transport quality of the insulated pipe.

[0024] (2) This utility model, through the setting of annular snap-fit ​​groove, first snap-fit ​​ball and bidirectional internal thread sleeve, etc., allows multiple circular plates to be connected through the first threaded rod, bidirectional internal thread sleeve and second threaded rod, etc., thereby connecting and fixing multiple pipes. At the same time, by controlling the length between the second snap-fit ​​ball and the first snap-fit ​​ball, the fixing tightness between multiple pipes can be controlled, so that the tightness between multiple insulated pipes can be adjusted according to actual transportation needs, thereby improving the transportation quality of the pipes.

Detailed Implementation

[0034] 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.

[0035] Example 1:

[0036] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, a thermal insulation pipe support device includes multiple thermal insulation pipes 31. Each thermal insulation pipe 31 has a circular plate 10 inside. Multiple telescopic snap-fit ​​components are provided on the outer circular surface of each circular plate 10. Each telescopic snap-fit ​​component has an arc-shaped support plate 18 at its output end. Each arc-shaped support plate 18 is in close contact with the inner circular surface of its adjacent thermal insulation pipe 31. The end face of the arc-shaped support plate 18 that contacts the thermal insulation pipe 31 is arc-shaped, so that the multiple arc-shaped support plates 18 will not damage the inner wall of the thermal insulation pipe 31 when supporting it.

[0037] Each circular plate 10 has an annular snap-fit ​​groove 21 on one side wall. A bidirectional internal threaded sleeve 25 is provided between every two adjacent circular plates 10. A first snap-fit ​​ball 22 is slidably provided at one end of each bidirectional internal threaded sleeve 25, and a second snap-fit ​​ball 33 is slidably provided at the other end of each bidirectional internal threaded sleeve 25. The first snap-fit ​​ball 22 and the first connecting block 23 have the same diameter. Each first snap-fit ​​ball 22 and the second snap-fit ​​ball 33 are slidably snap-fitted to their adjacent annular snap-fit ​​groove 21. By snapping the first snap-fit ​​ball 22 and the second snap-fit ​​ball 33 into their adjacent annular snap-fit ​​groove 21, multiple circular plates 10 can be connected and fixed to each other, thereby connecting and fixing multiple insulation pipes 31 to form a whole, making them more secure and stable during transportation.

[0038] Furthermore, such as Figure 5 and Figure 6As shown, the telescopic snap-fit ​​assembly includes a long plate 29 disposed on the outer circular surface of the circular plate 10. A first slide groove 11 is provided on one side wall of the long plate 29. A support slide plate 12 is slidably disposed inside the first slide groove 11. Each support slide plate 12 is fixedly connected to one side wall of its adjacent arc-shaped support plate 18. By sliding the support slide plate 12, the distance between the multiple arc-shaped support plates 18 is changed, thereby allowing the multiple arc-shaped support plates 18 to provide internal support according to the different sizes of the insulation pipes, thus increasing the adaptability of the device. Second slide grooves 13 are provided on the opposite side walls inside the first slide groove 11. Multiple one-way teeth 14 are slidably disposed inside each second slide groove 13. One end of each one-way tooth 14 is connected to its adjacent support slide plate 12. The sidewall is fixedly connected, and each second slide groove 13 has an elongated hole 15 on its inner sidewall. A rotating rod 16 is rotatably installed inside each elongated hole 15. One end of each rotating rod 16 is provided with a snap-fit ​​protrusion 30. Each snap-fit ​​protrusion 30 will snap with multiple adjacent one-way teeth 14. The multiple one-way teeth 14 slide inside the second slide groove 13, firstly to limit the sliding of the support slide plate 12. By rotating the elastic flap 17, the snap-fit ​​protrusion 30 is driven to snap with one of the one-way teeth 14, thereby controlling the joint length between the support slide plate 12 and the long plate 29, and then controlling the distance between the multiple arc-shaped support plates 18, so that the multiple arc-shaped support plates 18 provide stable support for the inner wall of the insulated pipe and ensure the stability of the pipe during transportation.

[0039] Furthermore, such as Figure 5 and Figure 6 As shown, each rotating rod 16 is connected to its adjacent long plate 29 by an elastic flap 17. The elastic flap 17 is a common elastic flap, and its elastic tension provides support to one end of the rotating rod 16. This allows the locking protrusion 30 at the other end of the rotating rod 16 to be securely engaged between the corresponding two one-way teeth 14. By pressing one end of the rotating rod 16, the elastic flap 17 is compressed, causing the locking protrusion 30 at the other end of the rotating rod 16 to disengage from the one-way teeth 14. The snap-fit ​​limit allows components such as the support slide plate 12 to move into the interior of the first slide groove 11. When it is necessary to increase the combined length of the support slide plate 12 and the long plate 29, the support slide plate 12 can be pulled to drive multiple one-way teeth 14 to slide inside the first slide groove 11. At this time, the multiple one-way teeth 14 will form a support for the adjacent snap-fit ​​protrusion 30, causing the snap-fit ​​protrusion 30 to disengage from the snap-fit ​​limit of the one-way teeth 14. However, under the elastic support of the elastic flap 17, the snap-fit ​​protrusion 30 will return to the snap-fit ​​limit of the one-way teeth 14 after the support slide plate 12 and the long plate 29 are relatively stationary.

[0040] Furthermore, such as Figure 8As shown, the two ends of the bidirectional internal threaded sleeve 25 are provided with opposite internal threads. One end of each bidirectional internal threaded sleeve 25 is threadedly connected to a first threaded rod 24. The outer surface of the first threaded rod 24 is provided with mutually threaded external threads. One end of each first threaded rod 24 is connected to a first connecting block 23. One side wall of each first connecting block 23 is fixedly connected to its adjacent first snap-fit ​​ball 22. The other end of each bidirectional internal threaded sleeve 25 is threadedly connected to a second threaded rod 26. The outer surface of the second threaded rod 26 is also provided with mutually threaded external threads. The external threads of the first threaded rod 24 and the second threaded rod 26 are arranged in opposite directions on their outer circular surfaces. This allows the distance between the first connecting block 23 and the second connecting block 32 to be shortened or increased when the bidirectional internal threaded sleeve 25 is rotated, thereby changing the length between the first snap-fit ​​ball 22 and the second snap-fit ​​ball 33, forming a fixation between the two circular plates 10, and thus forming a fixation between multiple heat-insulating pipes 31. Each second threaded rod 26 has a second connecting block 32 at one end, and one side wall of each second connecting block 32 is fixedly connected to its adjacent second snap-fit ​​ball 33.

[0041] Furthermore, such as Figure 3 As shown, a support rod 20 is connected between each pair of connected support slide plates 12 and arc-shaped support plates 18. The support rod 20 provides support between the support slide plates 12 and arc-shaped support plates 18, making the arc-shaped support plates 18 more stable when supporting the inner wall of the insulation pipe 31, thereby improving the stability of the device in supporting the insulation pipe 31.

[0042] Furthermore, such as Figure 5 As shown, each arc-shaped support plate 18 is provided with an anti-slip pad 19 on its arc-shaped end face. The anti-slip pad 19 is made of elastic anti-slip material and has multiple strip-shaped grooves on its end face. The anti-slip pad 19 effectively protects the inner wall of the pipe and prevents the arc-shaped support plate 18 from bumping or hitting the inner wall of the insulated pipe 31 when supporting it. It also makes the arc-shaped support plate 18 more secure when supporting the inner wall of the insulated pipe 31.

[0043] Furthermore, such as Figure 7 As shown, each annular snap-fit ​​groove 21 has an installation groove 27 on one side wall of the circular plate 10. The installation groove 27 is a channel for the first snap-fit ​​ball 22 and the second snap-fit ​​ball 33 to enter the interior of the annular snap-fit ​​groove 21. Each installation groove 27 is interconnected with its adjacent annular snap-fit ​​groove 21. Each installation groove 27 has a detachable limiting plate 28 inside. The limiting plate 28 is fixed inside the installation groove 27 by bolts, so that the first snap-fit ​​ball 22 or the second snap-fit ​​ball 33 entering the annular snap-fit ​​groove 21 will not detach from the interior of the annular snap-fit ​​groove 21, thereby improving the stability of the device.

[0044] When multiple insulated pipes 31 need to be fixed and transported, firstly, a circular plate 10 is placed inside both ends of each insulated pipe 31. By pulling multiple support slide plates 12 on the outside of each circular plate 10, multiple arc-shaped support plates 18 are driven, so that the anti-slip pads 19 on the outside of each arc-shaped support plate 18 abut against the inner wall of the insulated pipe 31. Then, the multiple insulated pipes 31 are placed inside the transport vehicle. A bidirectional internal threaded sleeve 25 is installed between every two circular plates 10, so that the first snap-fit ​​ball 22 and the second snap-fit ​​ball 33 set at both ends of the bidirectional internal threaded sleeve 25 snap into the annular snap-fit ​​groove 21 adjacent to the first snap-fit ​​ball 22 and the second snap-fit ​​ball 33. Then, by rotating the bidirectional internal threaded sleeve 25, the distance between the first connecting block 23 and the second connecting block 32 is adjusted, thereby forming multiple circular plates 10 to move closer to each other and fix them, thus completing the clamping and fixing of the insulated pipes.
