Description

Technical Field

[0001] This utility model belongs to the field of directional drilling pipeline welding technology, and in particular relates to a steel wire support for optical cable conduit. Background Technology

[0002] Directional drilling trenchless technology is widely used in long-distance pipeline projects. Due to the limited length of the pipeline prefabrication operation zone on the directional drilling site, the crossing of optical cable conduits requires "two-to-one" (welding two optical cable conduits together) or "multiple-to-one" (welding multiple optical cable conduits together) group welding. In order to introduce optical cables into the optical cable conduits after they are crossed, steel wire ropes need to be pre-installed inside the optical cable conduits. Then, the steel wire ropes pull the optical cables with silicon core tubes on the outside into the optical cable conduits.

[0003] Because it is necessary to assemble and weld two or more optical cable sleeves, during the assembly and welding process, since the steel wire rope is already threaded through multiple optical cable sleeves, it is easy for the steel wire rope to approach the weld joint of the optical cable sleeve due to gravity or bending. As a result, the steel wire rope is prone to quality problems such as burning and breakage at the weld joint of the optical cable sleeve due to welding slag spatter, leaving potential quality hazards for the subsequent traction of silicon core tubes and optical cables by the steel wire rope. Utility Model Content

[0004] To address the technical problems existing in the prior art, this application provides a simple structure, easy manufacturing, and fiber optic cable conduit insertion wire support that can prevent the steel wire rope from being burned or broken during fiber optic cable conduit welding.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A wire support for optical cable sheathing includes a support tube that can be inserted into the optical cable sheath, and a wire rope that can be inserted into the support tube; at least two connecting rings are fixedly sleeved on the support tube, and a plurality of elastic support arms are fixedly connected to each connecting ring; when the support tube is inserted into the optical cable sheath, the support arms abut against the inner wall of the optical cable sheath.

[0007] Preferably, the connecting ring is a spiral structure fixedly wound around the outer circumference of the support tube, and arc-shaped support arms are fixedly connected to the two leads of the connecting ring, with the two support arms respectively arranged on both sides of the support tube.

[0008] Preferably, a short nylon tube is fitted onto the support arm.

[0009] Preferably, the nylon short tube has a segmented structure.

[0010] Preferably, a stop is fixedly sleeved at the end of the support arm.

[0011] Preferably, a heat insulation layer is provided around the outer circumference of the support tube, and the connecting ring is fixedly sleeved on the outside of the heat insulation layer.

[0012] Preferably, the connecting ring is sleeved on the support tube, and a limiting ring is fixedly connected to the support tube on both sides of each connecting ring, wherein the outer diameter of the limiting ring is larger than the inner diameter of the connecting ring.

[0013] Preferably, an annular groove is formed on the outer circumference of the support tube, and the connecting ring is embedded in the annular groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention supports the steel wire rope by setting up a support pipe, a connecting ring, and a support arm, and covers the steel wire rope at the weld joint of the two optical cable sleeves by using the support pipe, ensuring that the steel wire rope at the weld joint is intact and easy to remove later. This avoids damage such as burns and breakage of the steel wire rope caused by high temperature welding slag during the welding of the optical cable sleeve assembly.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0025] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Example 1

[0026] See appendix Figure 1 , 2 As shown in Figure 3, a steel wire support for optical cable sheathing includes a support tube 2 that can be inserted into the optical cable sheath 1, and a steel wire rope 3 that can be inserted into the support tube 2. The structures of the optical cable sheath 1 and the steel wire rope 3 are both existing technologies. For example, in this embodiment, the optical cable sheath 1 is selected as an optical cable sheath with an inner diameter of 98mm, and the steel wire rope 3 is selected as a steel wire rope with a diameter of 10mm.

[0027] The support tube 2 is a circular tube structure. In this embodiment, the support tube 2 is selected as a high-temperature resistant PVC pipe or a flame-retardant ABS pipe with a length of 300mm and an outer diameter of 15mm. The inside of the support tube 2 is hollow so as to allow the steel wire rope 3 to be threaded through. Therefore, the inner diameter of the support tube 2 must be greater than 10mm and less than 15mm.

[0028] At least two connecting rings 4 are fixedly sleeved on the support tube 2. In this embodiment, two connecting rings 4 are provided, and the two connecting rings 4 are located on the outer circumference of the support tube 2 at a distance of 50 mm from each end of the support tube 2. Multiple elastic support arms 5 are fixedly connected to each connecting ring 4. When the support tube 5 passes through the optical cable sleeve 1, the support arms 5 abut against the inner wall of the optical cable sleeve 1, thereby positioning the support tube 2 in the middle of the optical cable sleeve 1 under the support of the support arms 5. At this time, the steel wire rope 3 located in the support tube 2 is also located in the middle of the optical cable sleeve 1 and is protected by the support tube 2 from being burned by welding slag or even broken.

[0029] Specifically, in this embodiment, the connecting ring 4 is a spiral structure fixedly wound around the outer circumference of the support tube 2. Arc-shaped support arms 5 are integrally formed and fixedly connected to the two leads of the connecting ring 4, with the two support arms respectively located on both sides of the support tube 2. That is, in the actual manufacturing of the connecting ring 4 and support arms 5, the connecting ring 4 and support arms 5 can be made of existing 8# specification 316 stainless steel wire. The middle part of this stainless steel wire is spirally wound around the support tube 2 to form the connecting ring 4, and the two ends of the stainless steel wire are respectively bent into arc shapes towards both sides of the support tube 2 to form the support arms 5. It should be noted that in order to support the support tube 2 in the middle position inside the optical cable sleeve 1, the bending angle of the support arm 5 can be adjusted according to the actual working conditions, so that the two support arms 5 abut against the inner circumference of the optical cable sleeve 1, thereby supporting the support tube 2. In addition, since the support arm 5 is made of stainless steel wire, it has a certain elasticity. The support arm 5 relies on its own elasticity to achieve the self-centering of the support tube 2 and the tight fit with the optical cable sleeve 2.

[0030] In practical use, after the two support arms 5 are spread out, the outer width of the two support arms 5 can be slightly smaller than the inner diameter of the optical cable sleeve 1 (e.g., the outer width of the two support arms is 95±2mm for an optical cable sleeve with an inner diameter of 98mm). Of course, since the support arms 5 have a certain degree of elasticity, the outer width of the two support arms 5 after they are spread out and not placed in the optical cable sleeve can also be larger than the inner diameter of the optical cable sleeve 1. After they are placed in the optical cable sleeve 1, the two support arms 5 will be squeezed to further compress them, thereby further improving the connection stability between the two support arms 5 and the inner circumference of the optical cable sleeve 1.

[0031] To ensure the connecting ring 4 is stably fixed to the support pipe 2, the connecting ring 4 and support arm 5 can be prefabricated in batches before construction, ensuring that the inner diameter of the connecting ring 4 is no larger than the outer diameter of the support pipe 2. Due to the elasticity of the connecting ring 4, it is fixedly fitted onto the outer circumference of the support pipe 2. Alternatively, the connecting ring 4 and support arm 5 can be fabricated on-site, with stainless steel wire tightly wound around the outer circumference of the support pipe 2 to form the connecting ring 4, preventing it from slipping off the support pipe 2 when it is pulled. Of course, to improve the connection strength of the connecting ring 4 wound around the support pipe 2, the two leads of the connecting ring 4 can be twisted together in a spiral shape using pliers, and then bent towards both sides of the support pipe 2 to form two support arms 5.

[0032] The working principle and process of this embodiment are as follows:

[0033] See Figure 5 , 6As shown, install each component according to the above instructions, and set up each optical cable sleeve 1 that needs to be assembled and welded in sequence, so that the weld joints 11 of the optical cable sleeve 1 are set opposite each other. A steel wire support for the optical cable sleeve is set between every two optical cable sleeves 1. The steel wire rope 3 is threaded through the optical cable sleeve 1 and the support pipe 2 in the order of optical cable sleeve 1, support pipe 2, and optical cable sleeve 1.

[0034] Adjust the steel wire support for the optical cable sheath, and position the support tube 2 in the middle of the weld joint of the two optical cable sheaths 1. Then, assemble the two optical cable sheaths 1 to be welded, and then perform circumferential welding at the weld joint 11 of the two optical cable sheaths 1. During the welding process, since the support arm 5 abuts against the inner wall of the optical cable sheath 1, the support arm 5 supports the support tube 2 and the steel wire rope 3 inside the support tube 2, so that the steel wire rope 3 is in the middle of the optical cable sheath 1 and is wrapped by the support tube 2. When welding the optical cable sheath 1, the high temperature welding slag will not come into contact with the steel wire rope 3, thereby avoiding damage to the steel wire rope 3.

[0035] After the optical cable conduit 1 is installed, the existing wire rope joint (not shown in the figure) can be fixed on the wire rope 3 at the entrance of the optical cable conduit 1. The outer diameter of the wire rope joint is larger than the inner diameter of the support pipe 2. When the wire rope 3 is pulled, the support pipe 2 blocks the wire rope joint, so the wire rope joint pushes the support pipe 2 and drives the support arm 5 to move forward, thereby driving the wire support of the optical cable conduit to be led out from the exit of the optical cable conduit 1, which will not affect the subsequent construction. Example 2

[0036] See Figure 3 As shown, this embodiment is a further improvement on the basis of embodiment 1. In order to prevent the support arm 5 from scratching the anti-corrosion layer of the inner wall of the optical cable sheath 1 when it is being pulled, a nylon short tube 7 is sleeved on each support arm 5.

[0037] To facilitate the fitting of the nylon short tube 7 onto the corresponding support arm 5, the nylon short tube 7 has a segmented structure. In this embodiment, each nylon short tube 7 can be designed as a nylon short tube with a length of 15-20mm and a wall thickness of 3mm. The inner diameter of the nylon short tube 7 can be designed to be no larger than the diameter of the support arm 5 to prevent the nylon short tube 7 from slipping off the support arm 5. Furthermore, a stop 8 can be fixedly fitted at the end of the support arm 5, and the outer diameter of the stop 8 is larger than the inner diameter of the nylon short tube 7.

[0038] The working principle and process of this embodiment are as follows:

[0039] See Figure 5 , 6As shown, install each component according to the above instructions, and set up each optical cable sleeve 1 that needs to be assembled and welded in sequence, so that the weld joints 11 of the optical cable sleeve 1 are set opposite each other. A steel wire support for the optical cable sleeve is set between every two optical cable sleeves 1. The steel wire rope 3 is threaded through the optical cable sleeve 1 and the support pipe 2 in the order of optical cable sleeve 1, support pipe 2, and optical cable sleeve 1.

[0040] Adjust the steel wire support for the optical cable sheath, and position the support tube 2 in the middle of the weld joint of the two optical cable sheaths 1. Then, assemble the two optical cable sheaths 1 to be welded, and then perform circumferential welding at the weld joint 11 of the two optical cable sheaths 1. During the welding process, since the nylon short tube 7 on the support arm 5 abuts against the inner wall of the optical cable sheath 1, the support arm 5 supports the support tube 2 and the steel wire rope 3 inside the support tube 2, so that the steel wire rope 3 is in the middle of the optical cable sheath 1 and is wrapped by the support tube 2. When welding the optical cable sheath 1, the high temperature welding slag will not come into contact with the steel wire rope 3, thereby avoiding damage to the steel wire rope 3.

[0041] After the optical cable conduit 1 is installed, an existing wire rope joint (not shown in the figure) can be fixed to the wire rope 3 at the entrance of the optical cable conduit 1. The outer diameter of the wire rope joint is larger than the inner diameter of the support pipe 2. When the wire rope 3 is pulled, the support pipe 2 obstructs the wire rope joint, thereby pushing the support pipe 2 and causing the support arm 5 to move forward. This, in turn, causes the wire support bracket for the optical cable conduit to be led out from the exit of the optical cable conduit 1, without affecting subsequent construction. During the adjustment of the wire support bracket and the removal of the wire support bracket after welding, the nylon short tube 7 abuts against the inner wall of the optical cable conduit 1, thus preventing the support arm 5 from scratching the anti-corrosion layer of the inner wall of the optical cable conduit 1. Example 3

[0042] Figure 1As shown, this embodiment is a further improvement on embodiment 2. To prevent high-temperature welding slag from splashing and burning the support pipe 2, a heat insulation layer 6 is wrapped around the outer circumference of the support pipe 2. The heat insulation layer 6 is a 1-2 mm thick glass fiber cloth or mica sheet wrapped around the outer circumference of the support pipe 2, forming a heat insulation barrier to prevent high-temperature welding slag from splashing and burning the support pipe 2, and to conduct heat to the steel wire rope 3. The connecting ring 4 is fixedly sleeved on the outside of the heat insulation layer 6. The way the connecting ring 4 is fixed on the heat insulation layer 6 is the same as the way the connecting ring 4 is directly fixed on the outer circumference of the support pipe 2 in embodiment 1. That is, the connecting ring 4 and the support arm 5 can be prefabricated in batches before construction so that the inner diameter of the connecting ring 4 is not greater than the outer diameter of the heat insulation layer 6. Since the connecting ring 4 has a certain degree of elasticity, the connecting ring 4 is fixedly sleeved on the outer circumference of the heat insulation layer 6. The connecting ring 4 and support arm 5 can also be fabricated on-site. The stainless steel wire can be tightly wound around the outer circumference of the insulation layer 6 to form the connecting ring 4, preventing it from slipping off the insulation layer 6 when the support tube 2 is pulled. Alternatively, to increase the connection strength of the connecting ring 4 wound around the insulation layer 6, pliers can be used to twist the two leads of the connecting ring 4 together in a spiral shape, and then they can be bent towards both sides of the support tube 2 to form two support arms 5.

[0043] The working principle and process of this embodiment are the same as those of embodiment 2:

[0044] See Figure 5 , 6 As shown, install each component according to the above instructions, and set up each optical cable sleeve 1 that needs to be assembled and welded in sequence, so that the weld joints 11 of the optical cable sleeve 1 are set opposite each other. A steel wire support for the optical cable sleeve is set between every two optical cable sleeves 1. The steel wire rope 3 is threaded through the optical cable sleeve 1 and the support pipe 2 in the order of optical cable sleeve 1, support pipe 2, and optical cable sleeve 1.

[0045] Adjust the steel wire support for the optical cable sheath, positioning the support tube 2 in the middle of the weld joint between the two optical cable sheaths 1. Then, assemble the two optical cable sheaths 1 to be welded, and perform circumferential welding at the weld joint 11 of the two optical cable sheaths 1. During the welding process, because the support arm 5 abuts against the inner wall of the optical cable sheath 1, the support arm 5 supports the support tube 2 and the steel wire rope 3 inside the support tube 2, placing the steel wire rope 3 in the middle of the optical cable sheath 1 and wrapping it with the support tube 2. The support tube 2 is covered by the heat insulation layer 6. When welding the optical cable sheath 1, the high-temperature welding slag will not come into contact with the steel wire rope 3 or the support tube 2, thus avoiding damage to the steel wire rope 3 and the support tube 2.

[0046] After the optical cable conduit 1 is installed, the existing wire rope joint (not shown in the figure) can be fixed on the wire rope 3 at the entrance of the optical cable conduit 1. The outer diameter of the wire rope joint is larger than the inner diameter of the support pipe 2. When the wire rope 3 is pulled, the support pipe 2 blocks the wire rope joint, thereby pushing the support pipe 2 and driving the support arm 5 to move forward. This will then drive the wire support bracket of the optical cable conduit to be led out from the exit of the optical cable conduit 1, without affecting the subsequent construction. Example 4

[0047] See Figure 1 As shown, this embodiment is a further improvement on embodiment 3. To facilitate the fixing of the optical cable conduit wire support on the support pipe 2, the connecting ring 4 is sleeved on the heat insulation layer 6 on the support pipe 2. Limiting rings 9 are fixedly connected to the heat insulation layer 6 on both sides of the support pipe 2 before and after each connecting ring 4. The outer diameter of the limiting ring 9 is larger than the inner diameter of the connecting ring 4, thereby preventing the connecting ring 4 from slipping off the heat insulation layer 6. To facilitate the fixing of the limiting ring 9 on the heat insulation layer 6, in this embodiment, the limiting ring 9 can be an existing stainless steel clamp. Since the limiting ring 9 blocks and limits the connecting ring 4, in this embodiment, the connecting ring 4 is fixed to the heat insulation layer 6 by the limiting ring 9. That is, when the limiting ring 9 is not set, the connecting ring 4 can slide on the heat insulation layer 6, thereby facilitating the adjustment of the relative position of the connecting ring 4 on the heat insulation layer 6.

[0048] The working principle and process of this embodiment are as follows:

[0049] See Figure 5 , 6 As shown, install each component according to the above instructions, and set up each optical cable sleeve 1 that needs to be assembled and welded in sequence, so that the weld joints 11 of the optical cable sleeve 1 are set opposite each other. A steel wire support for the optical cable sleeve is set between every two optical cable sleeves 1. The steel wire rope 3 is threaded through the optical cable sleeve 1 and the support pipe 2 in the order of optical cable sleeve 1, support pipe 2, and optical cable sleeve 1.

[0050] Adjust the steel wire support for the optical cable sheath, positioning the support tube 2 in the middle of the weld joint between the two optical cable sheaths 1. Then, assemble the two optical cable sheaths 1 to be welded, and perform circumferential welding at the weld joint 11 of the two optical cable sheaths 1. During the welding process, the nylon short tube 7 on the support arm 5 abuts against the inner wall of the optical cable sheath 1, and the support arm 5 supports the support tube 2 and the steel wire rope 3 inside the support tube 2. This ensures that the steel wire rope 3 is in the middle of the optical cable sheath 1 and is wrapped by the support tube 2. The support tube 2 is covered by the heat insulation layer 6. When welding the optical cable sheath 1, the high-temperature welding slag will not come into contact with the steel wire rope 3 or the support tube 2, thus avoiding damage to the steel wire rope 3 and the support tube 2.

[0051] After the optical cable conduit 1 is installed, an existing wire rope joint (not shown in the figure) can be fixed to the wire rope 3 at the entrance of the optical cable conduit 1. The outer diameter of the wire rope joint is larger than the inner diameter of the support pipe 2. When the wire rope 3 is pulled, the support pipe 2 obstructs the wire rope joint, thereby pushing the support pipe 2 and causing the support arm 5 to move forward. This, in turn, causes the wire support bracket for the optical cable conduit to be led out from the exit of the optical cable conduit 1, without affecting subsequent construction. During the adjustment of the wire support bracket and the removal of the wire support bracket after welding, the nylon short tube 7 abuts against the inner wall of the optical cable conduit 1, thus preventing the support arm 5 from scratching the anti-corrosion layer of the inner wall of the optical cable conduit 1. Example 5

[0052] See Figure 4 As shown, this embodiment is a further improvement on embodiment 2. To prevent the connecting ring 4 from slipping off the support tube 2, two annular grooves 21 are formed on the outer circumference of the support tube 2, and the connecting ring 4 is embedded in the annular grooves 21. In this embodiment, when manufacturing the connecting ring 4, the stainless steel wire can be directly wound around the support tube 2 in the annular groove 21. At this time, the inner diameter of the connecting ring 4 is smaller than the outer diameter of the support tube 2.

[0053] The working principle and process of this embodiment are as follows:

[0054] Install each component according to the above instructions, and set up each optical cable sleeve 1 that needs to be assembled and welded in sequence, so that the weld joints 11 of the optical cable sleeve 1 are set opposite each other. A steel wire support for the optical cable sleeve is set between every two optical cable sleeves 1. The steel wire rope 3 is threaded through the optical cable sleeve 1 and the support pipe 2 in the order of optical cable sleeve 1, support pipe 2, and optical cable sleeve 1.

[0055] Adjust the steel wire support for the optical cable sheath, and position the support tube 2 in the middle of the weld joint of the two optical cable sheaths 1. Then, assemble the two optical cable sheaths 1 to be welded, and then perform circumferential welding at the weld joint 11 of the two optical cable sheaths 1. During the welding process, since the nylon short tube 7 on the support arm 5 abuts against the inner wall of the optical cable sheath 1, the support arm 5 supports the support tube 2 and the steel wire rope 3 inside the support tube 2, so that the steel wire rope 3 is in the middle of the optical cable sheath 1 and is wrapped by the support tube 2. When welding the optical cable sheath 1, the high temperature welding slag will not come into contact with the steel wire rope 3, thereby avoiding damage to the steel wire rope 3.

[0056] After the optical cable conduit 1 is installed, an existing wire rope joint (not shown in the figure) can be fixed to the wire rope 3 at the entrance of the optical cable conduit 1. The outer diameter of the wire rope joint is larger than the inner diameter of the support pipe 2. When the wire rope 3 is pulled, the support pipe 2 obstructs the wire rope joint, thereby pushing the support pipe 2 and causing the support arm 5 to move forward. This, in turn, causes the wire support bracket for the optical cable conduit to be led out from the exit of the optical cable conduit 1, without affecting subsequent construction. During the adjustment of the wire support bracket for the optical cable conduit and the removal of the wire support bracket after welding, the nylon short tube 7 abuts against the inner wall of the optical cable conduit 1, thus preventing the support arm 5 from scratching the anti-corrosion layer of the inner wall of the optical cable conduit 1.

[0057] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
