Description

Technical Field

[0001] This invention belongs to the field of municipal engineering, and in particular relates to an auxiliary device for laying optical cables in pipelines. Background Technology

[0002] This is one method of laying optical fiber cables. Duct laying is generally used in urban areas where the environment is relatively good, therefore there are no special requirements for the cable sheath and armoring is unnecessary. Before laying the cable in the duct, the length of the laying section and the location of the splicing points must be selected. Laying can be done using mechanical bypass or manual traction.

[0003] In typical fiber optic cable laying operations, manual traction is used. The cable is pulled from one end of the manhole through a group of pipe holes to the other end of the manhole using a conduit puller. The fiber optic cable is then connected to the conduit puller, and the puller is pulled back to complete the fiber optic cable laying process.

[0004] In practice, when the cable puller is pulled back, personnel are still needed at the opposite well pit to help straighten the optical cable. This means that personnel are needed at both ends to assist in the installation of the optical cable, and the installation of optical cables in pipelines requires a large number of personnel. Summary of the Invention

[0005] The purpose of this invention is to provide an auxiliary device for laying optical cables in pipelines, which aims to solve the problem that personnel are required to assist in the operation at both ends during the laying process.

[0006] The present invention is implemented as follows: a pipeline optical cable laying auxiliary device includes a first support arranged in parallel, the first supports being connected to each other by a crossbeam, and also includes a first auxiliary wheel, a second auxiliary wheel, an adjusting support frame and a second support.

[0007] The first auxiliary wheel is rotatably mounted on the first bracket, the adjusting support frame is mounted on the side of the crossbeam away from the first auxiliary wheel, the second bracket is fixed on the adjusting support frame, the second auxiliary wheel is rotatably connected to the second bracket, the second auxiliary wheel is located on one side of the first auxiliary wheel, and there is a horizontal spacing and a vertical spacing between the first auxiliary wheel and the second auxiliary wheel.

[0008] The adjustable support frame includes a mounting block, a first telescopic member, and a second telescopic member. Both the first and second telescopic members are fixed on the mounting block. The first telescopic member is horizontally positioned between the first and second auxiliary wheels, and the second telescopic member is vertically positioned between the first and second auxiliary wheels. The other end of the first telescopic member is fixedly connected to the crossbeam, and the other end of the second telescopic member is fixedly connected to the second bracket.

[0009] Preferably, the outer side of the first bracket is fixed with a support member.

[0010] Preferably, the middle part of the first auxiliary wheel and the second auxiliary wheel has an arc-shaped concave structure.

[0011] Preferably, the first and second auxiliary wheels are made of rubber.

[0012] Preferably, the first telescopic member includes an insert fixed on the mounting block and a sleeve fixed on the crossbeam. The insert is inserted into the sleeve. The mounting block is provided with a rotating threaded rod located inside the insert. A sleeve is fixed on the crossbeam and located inside the sleeve. The threaded rod is connected to the sleeve. The mounting block is provided with a driving member for driving the threaded rod to rotate. The second telescopic member adopts the same structure.

[0013] Preferably, the driving component can be a turntable fixedly connected to a threaded rod, and a handle is fixed on the turntable.

[0014] Preferably, both the insertion tube and the sleeve are made of tubing with a rectangular cross-section.

[0015] Preferably, the outer diameter of the socket is smaller than the inner diameter of the long tube.

[0016] Preferably, the second telescopic member is located on one side of the first telescopic member.

[0017] The beneficial effects of the duct optical cable laying auxiliary device provided by this invention are as follows: When in use, the device is first placed on the pit, and the optical cable is wound around the first auxiliary wheel and the second auxiliary wheel. This can replace the manual straightening of the optical cable, ensuring that when the optical cable is pulled out from the other end through the pipe puller, the optical cable enters the pipe smoothly from this section. Moreover, for pipes in different locations in different pits, the relative positions of the second auxiliary wheel and the first auxiliary wheel can be changed through the first telescopic member and the second telescopic member, increasing the adaptability of the device and effectively reducing the manpower input during laying.

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0026] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0027] like Figure 2 The diagram shown illustrates the structure of an auxiliary device for laying optical cables in a duct, according to an embodiment of the present invention. The device includes:

[0028] The first support 1 is arranged in parallel, and the first support 1s are connected by a crossbeam, the first auxiliary wheel 2, the second auxiliary wheel 3, the adjusting support frame 4, and the second support 5.

[0029] The first auxiliary wheel 2 is rotatably mounted on the first bracket 1, the adjusting support frame 4 is mounted on the side of the crossbeam away from the first auxiliary wheel 2, the second bracket 5 is fixed on the adjusting support frame 4, the second auxiliary wheel 3 is rotatably connected to the second bracket 5, and the second auxiliary wheel 3 is located on one side of the first auxiliary wheel 2.

[0030] The adjustable support frame 4 includes a mounting block 401, a first telescopic member 402, and a second telescopic member 403. Both the first telescopic member 402 and the second telescopic member 403 are fixed on the mounting block 401. The first telescopic member 402 is horizontally positioned between the first auxiliary wheel 2 and the second auxiliary wheel 3, and the second telescopic member 403 is vertically positioned between the first auxiliary wheel 2 and the second auxiliary wheel 3. The other end of the first telescopic member 402 is fixedly connected to the crossbeam, and the other end of the second telescopic member 403 is fixedly connected to the second bracket 5.

[0031] In one embodiment of the present invention, when the device is used, it is first placed on the pit 6, and the optical cable 9 is wound around the first auxiliary wheel 2 and the second auxiliary wheel 3. This can replace the manual route straightening function and ensure that when the optical cable 9 is pulled out from the other end through the pipe puller, the optical cable 9 enters the pipe smoothly from this section. Moreover, for pipes in different locations in different pits 6, the relative positions of the second auxiliary wheel 3 and the first auxiliary wheel 2 can be changed by the first telescopic member 402 and the second telescopic member 403, which increases the adaptability of the device and effectively reduces the manpower input during laying.

[0032] In one embodiment of the present invention, the first telescopic member 402 and the second telescopic member 403 can be electric telescopic rods, and support members 7 are fixed to the outer sides of the first bracket 1. The support members 7 can be horizontal plates, such as... Figure 1 As shown, the horizontal plate is placed horizontally on the pit 6. The first auxiliary wheel 2 is located outside the pit 6, while the second auxiliary wheel 3 is located inside the pit 6. The optical cable 9 is wound around the first auxiliary wheel 2 and the second auxiliary wheel 3. Pipe hole groups 8 are provided on the side wall of the pit 6. Since the positions of pipe hole groups 8 are different in different pits 6, the position of the second auxiliary wheel 3 can be adjusted adaptively.

[0033] like Figure 2 As shown, in a preferred embodiment of the present invention, the middle part of the first auxiliary wheel 2 and the second auxiliary wheel 3 is an arc-shaped concave structure.

[0034] In one embodiment, the recessed structure of the first auxiliary wheel 2 and the second auxiliary wheel 3 ensures that the optical cable 9 is in the middle position when it is wound around the two. The position of the first auxiliary wheel 2 is more accurate when it is adjusted, and the optical cable 9 is also prevented from deflecting. The first auxiliary wheel 2 and the second auxiliary wheel 3 are made of rubber. Both of them are made of this material and have a certain degree of elasticity, which avoids wear on the optical cable 9 itself and increases the friction.

[0035] like Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, in a preferred embodiment of the present invention, the first telescopic member 402 includes an insertion tube 4021 fixed on the mounting block 401 and a sleeve 4022 fixed on the crossbeam. The insertion tube 4021 is inserted into the sleeve 4022. A rotating threaded rod 4023 is provided on the mounting block 401, and the threaded rod 4023 is located inside the insertion tube 4021. A sleeve 4024 is fixed on the crossbeam, and the sleeve 4024 is located inside the sleeve 4022. The threaded rod 4023 is connected to the sleeve 4024. A driving member 4025 is provided on the mounting block 401, and the driving member 4025 is used to drive the threaded rod 4023 to rotate. The second telescopic member 403 adopts the same structure.

[0036] In one embodiment, the socket 4024 can be an internal threaded sleeve, and the drive 4025 can be a micro motor that drives the threaded rod 4023 to rotate. Alternatively, the drive 4025 can be a turntable 40251 fixedly connected to the threaded rod 4023. The turntable 40251 has a handle 40252; rotating the turntable 40251 via the handle 40252 causes the threaded rod 4023 to rotate, resulting in axial displacement of the threaded rod 4023 within the socket 4024. This causes the insertion tube 4021 to move within the sleeve 4022. Both the sleeve 4022 and the telescopic component 403 adopt a rectangular tube structure, which can prevent deflection during telescopic movement. The overall structure of the first telescopic component 402 and the second telescopic component 403 is as follows: the outermost part is the sleeve 4022, the inner part is the insertion tube 4021, the innermost part is the connecting piece 4024, and the core is the threaded rod 4023. The first telescopic component 402 is located on one side of the second telescopic component 403 on the mounting block 401, which ensures that the rotation between the two threaded rods 4023 does not interfere. Compared with the first telescopic component 402 and the second telescopic component 403 mentioned above, this telescopic structure does not have an automatic function, but it is more robust and reliable in actual use.

[0037] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0038] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
