Description

Technical Field

[0001] This application relates to the field of communication pipeline installation equipment, and in particular to a support device for relocating communication pipelines. Background Technology

[0002] When constructing underground communication cables, it is often necessary to pass the cables through underground communication ducts, which then provide protection for the cables. During the laying of these ducts, lifting equipment is required to move them into the trench. This lifting equipment needs to be connected to the duct via a support system to facilitate the lifting and transport of the duct.

[0003] An existing support device includes two hooks 51 and a lifting rope 52. Each hook 51 is connected to a lifting device via a lifting rope 52. The two hooks 51 are inserted into the two ends of a communication pipe 4, and the ends of the communication pipe 4 are hooked by the hooks 51 to enable the lifting device to lift the communication pipe 4. In the prior art, when the communication pipe 4 is lifted, the two hooks 51 will squeeze the communication pipe 4 towards its center, and the middle part of the communication pipe 4 will bend and sag under the action of gravity. Under the combined action of the squeezing of the hooks 51 and its own bending and sag, the communication pipe 4 may break, resulting in a decrease in the safety of the communication pipe 4 during the relocation process. Utility Model Content

[0004] To address the issue of communication pipelines breaking under the combined effects of hook compression and their own bending and sagging, which reduces the safety of the pipelines during relocation, this application provides a support device for relocating communication pipelines.

[0005] The support device for relocating communication pipelines provided in this application adopts the following technical solution:

[0006] A support device for relocating communication pipelines includes a support frame connected to hoisting equipment for supporting the communication pipelines;

[0007] The hooks are set on the support frame and correspond one-to-one with the ports of the communication pipe. They can be inserted into the communication pipe and axially fix the communication pipe.

[0008] A clamping support assembly is disposed on the support frame and is capable of clamping and fixing the middle part of the communication pipe to form a support for the communication pipe.

[0009] The support frame includes a middle support body and two edge bodies. The middle support body is located between the two edge bodies. Each edge body is connected to the middle support body through a telescopic rod. The hooks correspond one-to-one with the edge bodies and are provided on the edge bodies. The clamping support assembly is provided on the middle support body.

[0010] By adopting the above technical solution, during the hoisting and relocation of communication pipelines, the support frame uses two hooks to secure the communication pipeline at its two ends. The clamping support assembly then clamps and fixes the middle section of the pipeline. The support frame can withstand the compressive force applied by the two hoisting ropes, and the support provided by the clamping support assembly to the middle section of the pipeline effectively prevents sagging, thus avoiding pipeline breakage and improving the safety of the communication pipeline during relocation. The middle support body and the edge body of the support frame are connected by telescopic rods, allowing adjustment of their distance. This enables the hooks to adapt to communication pipelines of different lengths, facilitating the installation and disassembly of the pipeline and improving the versatility and ease of use of the support device.

[0011] Preferably, the support frame further includes a guide rod, which is arranged along the axial direction of the communication pipe and fixedly connected to the intermediate support body. The guide rod slides through the two edge bodies, and each edge body is threaded with a locking bolt, which can be tightened and fixed with the guide rod.

[0012] By adopting the above technical solution, the guide rod allows the two edge bodies to slide along the axial direction of the communication pipe, which facilitates the adjustment of the distance between the two hooks to adapt to communication pipes of different lengths. The locking bolt can fix the edge bodies to the guide rod, ensuring the stability of the support device during hoisting.

[0013] Preferably, the clamping support assembly includes a fastener and two clamping plates, each of which is rotatably connected to the intermediate support body. The two clamping plates are located on both sides of the communication pipe, and both clamping plates can be rotated to the bottom of the communication pipe to form support for the communication pipe. The fastener can fix the two clamping plates.

[0014] By adopting the above technical solution, two rotatable clamping plates can be rotated to support the communication pipe below, and then fasteners are used to fix the two clamping plates, which enhances the stable support for the middle part of the communication pipe.

[0015] Preferably, the fasteners correspond one-to-one with the clamping plates; the fasteners include fastening screws, threaded sleeves, and transmission structures. The threaded sleeves are fixedly connected to the intermediate support body, and the fastening screws are threaded into the threaded sleeves and connected to the clamping plates through the transmission structure so as to drive the clamping plates to rotate.

[0016] By adopting the above technical solution, the threaded engagement between the threaded sleeve and the fastening screw can be used to precisely control the movement distance of the fastening screw. In turn, the transmission structure can accurately drive the clamping plate to rotate, thereby more effectively clamping and fixing the communication pipeline and improving the stability and convenience of supporting the middle part of the communication pipeline.

[0017] Preferably, the transmission structure includes a transmission rack and a transmission gear. The transmission gear is coaxially fixed on the rotating shaft of the clamping plate. The fastening screw is rotatably connected to the transmission rack so as to drive the transmission rack to move. The transmission rack is meshed with the transmission gear.

[0018] By adopting the above technical solution, the linear motion of the fastening screw can be converted into the rotation of the clamping plate through the meshing connection of the transmission rack and gear. The rotation of the clamping plate can be precisely controlled to support the middle part of the communication pipeline, making the operation simpler and more stable.

[0019] Preferably, the clamping plate is provided with a clamping arc surface, and the clamping plate contacts the communication pipe through the clamping arc surface.

[0020] By adopting the above technical solution, the clamping arc surface of the clamping plate can increase the contact area with the communication pipeline, making the support for the communication pipeline more stable, further enhancing the support effect on the middle part of the communication pipeline, better preventing the communication pipeline from sagging and breaking, and improving the safety of the communication pipeline relocation process.

[0021] Preferably, each of the hooks is fixedly provided with a clamping screw, the clamping screw is slidably passed through the edge body, and a fixing nut is threaded on the clamping screw, the fixing nut being able to abut against the edge body so that the hook supports the communication pipe.

[0022] By adopting the above technical solution, the position of the fixing nut on the clamping screw can be adjusted to make the hook firmly support the communication pipeline, further enhancing the stability of the connection between the support device and the communication pipeline, and improving the stability and safety of the communication pipeline during hoisting.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The support frame bears the pressure of the lifting rope, and the clamping support components clamp and support the middle part of the communication pipeline, reducing the sagging of the communication pipeline and avoiding the phenomenon of breakage caused by the combined effect of pressure and bending sagging, thereby improving the safety of the communication pipeline during hoisting and relocation.

[0025] 2. The middle support body and the edge body of the support frame are connected by telescopic rods, and the distance between them can be adjusted so that the hook can be adapted to communication pipes of different lengths, improving the versatility and ease of use of the support device;

[0026] 3. The position of the adjustable fixing nut on the clamping screw ensures that the hook firmly supports the communication pipe, enhancing the stability of the connection between the support device and the communication pipe. Attached Figure Description

[0032] The following will be combined with the appendix Figures 2-4 The technical solutions in the embodiments of this utility model are described in further detail below. The described embodiments are only possible technical implementations of this utility model, but are not limited thereto. Other embodiments obtained by those skilled in the art in conjunction with the embodiments of this utility model without creative effort are also within the protection scope of this utility model.

[0033] This application mainly uses a support frame 1 in conjunction with a clamping support component 3 to lift the pipeline, which achieves the effect of avoiding pipeline breakage and improving the safety of relocation. The following is a further detailed description of this application.

[0034] This application provides a support device for relocating communication pipelines.

[0035] Reference Figure 2A support device for relocating a communication pipeline includes a support frame 1, hooks 2, and clamping support components 3. In this embodiment, there are two hooks 2, located at both ends of the support frame 1, and one set of clamping support components 3, located on the support frame 1 and aligned with the middle part of the communication pipeline 4. During the hoisting and relocation of the communication pipeline 4, the two hooks 2 hook the two ends of the communication pipeline 4, and the clamping support components 3 clamp and fix the middle part of the communication pipeline 4. The support frame 1 can withstand the compressive force applied by the two hoisting ropes, and the support formed by the clamping support components 3 on the middle part of the communication pipeline 4 can effectively prevent the communication pipeline 4 from sagging. Through the support of the support frame 1, the communication pipeline 4 is prevented from breaking due to the combined effect of compressive force and bending sagging, thereby improving the safety of the communication pipeline 4 during hoisting and relocation.

[0036] Reference Figure 2 The support frame 1 includes a middle support body 11 and two edge bodies 12. The middle support body 11 and the two edge bodies 12 are all V-shaped structures, and a V-shaped space is formed at the bottom for the communication pipe 4 to be inserted. The V-shaped structure of the middle support body 11 and the two edge bodies 12 facilitates the contact and restriction between the middle support body 11, the edge bodies 12 and the communication pipe 4, and improves the stability of the fixed connection between the communication pipe 4 and the support frame 1.

[0037] Reference Figure 2 The intermediate support 11 is located between the two edge bodies 12. The intermediate support 11 corresponds to the middle part of the communication pipe 4, and the two edge bodies 12 correspond to the two ends of the communication pipe 4 respectively. Each edge body 12 is connected to the intermediate support 11 by a telescopic rod 13. In this embodiment, the telescopic rod 13 includes an intermediate screw 131 and two threaded cylinders 132. The two threaded cylinders 132 are fixed on the edge body 12 and the intermediate support 11 respectively and are arranged opposite to each other. The intermediate screw 131 is arranged along the axial direction of the communication pipe 4. The two ends of the intermediate screw 131 are respectively inserted into the two threaded cylinders 132. The intermediate screw 131 has two threaded sections with opposite directions of thread that are symmetrically distributed along the middle. The intermediate screw 131 is threadedly connected to the two threaded cylinders 132 and the threads are opposite in direction. By rotating the intermediate screw 131, the edge body 12 moves closer to and away from the intermediate support 11. The middle support body 11 and the edge body 12 of the support frame 1 are connected by a telescopic rod 13, and the distance between the two can be adjusted so that the hook 2 can be adapted to communication pipes 4 of different lengths. At the same time, it is convenient to install and disassemble the communication pipes 4, which improves the versatility and ease of use of the support device.

[0038] Reference Figure 2On both sides of the intermediate support 11, a set of guide rods 14 are fixedly arranged along the axial direction of the intermediate screw 131. Each set of guide rods 14 consists of two rods, symmetrically arranged along the intermediate screw 131. Each guide rod 14 slides through the edge body 12, guiding the sliding of the edge body 12 and improving its stability. Each edge body 12 has two locking bolts 15, corresponding one-to-one with the guide rods 14. The locking bolts 15 are threaded into the edge body 12, with their ends facing the guide rods 14. Rotating the locking bolts 15 tightens them against the guide rods 14, thus fixing the guide rods 14 to the edge body 12. After the edge body 12 is adjusted, rotating the locking bolts 15 tightens them against the guide rods 14, improving the overall stability of the support frame 1, reducing the squeezing effect on the communication pipe 4 during hoisting, and thus improving safety during hoisting and relocation.

[0039] Reference Figure 2 Each edge body 12 is fixedly equipped with a lifting ring 16 for mounting a lifting rope on a lifting device. The ends of the two edge bodies 12 that are far apart from each other protrude to form mounting seats 17. Each hook 2 is fixedly equipped with a clamping screw 18, which is arranged radially along the communication pipe 4. The hook 2 is cylindrical and perpendicular to the clamping screw 18, forming an L-shaped structure. The clamping screw 18 passes through the mounting seat 17, and a fixing nut 19 is threaded onto the portion of the clamping screw 18 that passes through the mounting seat 17. During installation of the communication pipe 4, the hook 2 is inserted through the end opening of the communication pipe 4, and then the fixing nut 19 is rotated. When the fixing nut 19 abuts against the mounting seat 17, the hook 2 presses the communication pipe 4 against the edge body 12, and the clamping screw 18 fits against the end of the communication pipe 4, preventing axial sliding of the communication pipe 4. The position of the adjustable fixing nut 19 on the clamping screw 18 allows the hook 2 to firmly support the communication pipe 4, further enhancing the stability of the connection between the support device and the communication pipe 4, and improving the stability and safety of the communication pipe 4 during hoisting.

[0040] Reference Figure 2In this embodiment, the clamping support assembly 3 includes a fastener 31 and two clamping plates 32. Both ends of the intermediate support body 11 have hinge interfaces 33. The two clamping plates 32 are respectively disposed at both ends of the intermediate support body 11. The end of each clamping plate 32 is inserted into the corresponding hinge interface 33 and is rotatably connected to the intermediate support body 11 via a rotating shaft 34. The rotating shaft 34 is fixedly connected to the clamping plate 32. The free end of the clamping plate 32 can move below the communication pipe 4, and this end is bent to form a clamping arc surface 35. The two clamping plates 32 support the communication pipe 4 by lifting it. The clamping plates 32 contact the communication pipe 4 through the clamping arc surface 35. The clamping arc surface 35 of the clamping plate 32 increases the contact area with the communication pipe 4, making the support for the communication pipe 4 more stable and further enhancing the support effect on the middle part of the communication pipe 4.

[0041] Reference Figure 2 , Figure 3 and Figure 4 In this embodiment, the fasteners 31 and clamping plates 32 correspond one-to-one. The fasteners 31 include fastening screws 311, threaded sleeves 312, and transmission structures 313. The threaded sleeves 312 are fixedly mounted on the intermediate support 11 along the direction of the vertical communication pipe 4 axis, and the fastening screws 311 are threadedly inserted into the threaded sleeves 312. The transmission structure 313 includes a transmission rack 3131 and a transmission gear 3132. The transmission gear 3132 is coaxially fixed on the rotating shaft 34. The transmission rack 3131 and the transmission gear 3132 are meshed and connected. The end of the transmission rack 3131 forms a rotating ring 3133, and the end of the fastening screw 311 forms a stepped annular groove 36. The rotating ring 3133 is inserted into the stepped annular groove 36 and rotated to achieve the rotational connection between the fastening screw 311 and the transmission rack 3131, and allows the fastening screw 311 to pull the transmission rack 3131 to slide. A limiting ring 37 is provided on the intermediate support body 11. The transmission rack 3131 passes through the limiting ring 37 and slides in contact with the limiting ring 37. The limiting ring 37 can restrict the transmission rack 3131 from disengaging from the transmission gear 3132, so as to improve the stability of the transmission between the transmission rack 3131 and the transmission gear 3132.

[0042] By utilizing the threaded engagement between the threaded sleeve 312 and the fastening screw 311, the movement distance of the fastening screw 311 can be precisely controlled. Then, through the transmission structure 313 composed of the transmission rack 3131 and the transmission gear 3132, the clamping plate 32 is accurately driven to rotate, which more effectively clamps and fixes the communication pipe 4, improving the stability and convenience of supporting the middle part of the communication pipe 4.

[0043] The implementation principle of the support device for relocating a communication pipeline according to an embodiment of this application is as follows: During the hoisting and relocation of the communication pipeline 4, the support frame 1 is placed on the communication pipeline 4, the intermediate support body 11 is located in the middle part of the communication pipeline 4, and then the two edge bodies 12 are adjusted to a position suitable for the length of the communication pipeline 4 by driving the intermediate screw 131 to rotate. Then, the hook 2 is inserted into the communication pipeline 4, and the fixing nut 19 is rotated. The fixing nut 19 pulls the hook 2 to abut the communication pipeline 4 against the edge body 12. Then, the fastening screw 311 is driven to rotate. The fastening screw 311 drives the transmission rack 3131 to rotate. The transmission rack 3131 drives the transmission gear 3132 to rotate, so that the two clamping plates 32 rotate relative to each other. The free end of the clamping plate 32 rotates to the bottom of the communication pipeline 4. At this time, the clamping plate 32 forms support for the middle part of the communication pipeline 4. When the communication pipeline 4 is hoisted, the support frame 1 can withstand the compressive force applied by the two hoisting ropes, and the support formed by the clamping support component 3 on the middle part of the communication pipeline 4 can effectively prevent the communication pipeline 4 from sagging, thereby preventing the communication pipeline 4 from breaking and improving the safety of the communication pipeline 4 during the relocation process.

[0044] When disassembling the support frame 1 from the communication pipe 4, rotate the fastening screw 311 and the fixing nut 19 in the opposite direction so that the distance between the two clamping plates 32 is greater than the diameter of the communication pipe 4, and remove the hook 2 from the communication pipe 4. Then lift the support frame 1 to separate it from the communication pipe 4, thus completing the disassembly of the support frame 1 from the communication pipe 4.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
