Description

Technical Field

[0001] This utility model relates to the field of cable laying technology, and in particular to an auxiliary device for laying cables in cable trays on overhead pipelines. Background Technology

[0002] Currently, factory areas typically consist of multiple functional zones, such as production areas, storage areas, office areas, and living areas. External power cables connect the power and communication systems of these areas, enabling power distribution and signal exchange between them. Various production machinery and equipment within the factory, such as large machine tools, production lines, and cranes, require a stable power supply to operate normally. External power cables act like "power arteries," transmitting electricity from substations or main distribution rooms to distribution boxes or control cabinets near these devices, providing power for production activities.

[0003] The laying of cables outside the factory area usually takes the form of cable laying in cable trays on overhead ducts within the factory area, direct burial of cables, and cable laying in cable trenches. Among these three laying methods, cable laying in cable trays on overhead ducts is the most complex in terms of construction organization and technical difficulty.

[0004] The current common practice is to pull the cables onto an overhead pipeline platform, where sufficient personnel are deployed to place the cables section by section at the bottom of the cable trays or at designated layer positions. For multiple cables, they must be arranged in layers according to design requirements. The disadvantage of this method is the high manpower required and the significant risks associated with working at heights. Another approach is to lay the cables on the ground using winches and pulleys on straight sections, and then use manual labor and a crane to manually lower the cables into the cable trays for arrangement and securing. The disadvantage of this method is that it is greatly affected by site conditions, and its implementation becomes more difficult if the overhead pipeline network has a complex layout.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings.

[0026] Reference Figures 1 to 4 This utility model discloses an auxiliary device 1 for laying cables in cable trays on overhead pipelines, comprising a cable slide 10 and multiple sliders 11. The cable slide 10 is fixed to the steel purlin 20 of the overhead pipeline 2 along the cable laying direction. The multiple sliders 11 are all sleeved on the outer peripheral wall of the cable 6 to be laid and are all located inside the cable slide 10. The multiple sliders 11 can slide along the cable slide 10. Compared with traditional construction methods, it reduces the input of manpower, avoids the need for too many people to work at heights, and reduces construction dangers. At the same time, it improves construction efficiency.

[0027] The traction rope of the external winch 5 is connected to the starting end of the cable to be laid 6 through the cable traction net sleeve, and multiple sliders 11 slide along the cable slide 10 as the traction rope applies tension to the cable to be laid 6.

[0028] The usage process of the auxiliary device 1 for cable laying in the cable tray of the overhead pipeline provided in this embodiment is as follows: the cable slide 10 is fixed to the steel purlin 20 of the overhead pipeline 21 according to the cable laying direction. Multiple sliders 11 are sleeved on the outer peripheral wall of the cable 6 to be laid. The multiple sliders 11 slide along the cable slide 10 in the cable slide 10 with the pulling force applied to the cable 6 to be laid by the traction rope of the winch 5. When the slider 11 leaves the sliding cavity of the cable slide 10, since the slider is no longer constrained by the sliding cavity, the slider 11 falls off the cable 6 to be laid and falls at the outlet of the sliding cavity under the action of gravity. After the cable 6 is laid in place, the fixing device 4 is used to fix the cable 6 to be laid to the bottom end of the column of the overhead pipeline 2. The cable slide 10 is opened, the cable 6 to be laid is taken out and placed in the cable tray 3, and the cable tray cover is installed.

[0029] Continue to refer to Figure 7 In this embodiment, after the cable 6 to be laid is laid in place, a fixing device 4 is used to fix the cable 6 to the bottom of the column base of the overhead pipeline 2. The fixing device 4 includes a clamp 41 and two steel wire ropes 42. Pull rings are provided on the outer peripheral walls of opposite sides of the clamp 41. One end of the two steel wire ropes 42 is connected to the two pull rings respectively, and the other end of the two steel wire ropes 42 is connected to the bottom of the two column bases respectively. The clamp 41 is tightened to the cable 6 by tightening the bolts on the clamp 41 to reduce the inner diameter of the clamp 41.

[0030] During use, after the cable 6 is laid in place, the clamp 41 is fastened to the outer periphery of the section of the cable 6 that extends out of the cable slide rail; one end of the wire rope 42 is connected to the pull ring, and the other end of the wire rope 42 is connected to the hanging ring at the bottom of the column foot to fix the cable 6 and prevent the cable 6 from falling back.

[0031] Continue to refer to Figure 2 and Figure 3 In this embodiment, the cable slide 10 includes multiple slide units 11, which are detachably connected sequentially along the cable laying direction; this configuration increases the applicability of the cable slide 10.

[0032] The slide unit 11 includes a housing 1011, a cover plate 1012, and multiple gears 1014. The cover plate 1012 covers the housing 1011 and is rotatably connected to the housing 1011. The housing 1011 forms a cavity, which is divided into a first cavity and a second cavity. The first cavity and the second cavity are connected and arranged sequentially from top to bottom. Multiple gears 1014 are arranged in the second cavity and are spaced apart along the extension direction of the second cavity. All gears 1014 are rotatable relative to the housing 1011. The multiple first cavities are connected, and the multiple second cavities are connected.

[0033] Specifically, the cover plate 1012 is rotatably connected to the housing 1011 via a hinge. The first cavity is used to place the slider 11 wrapped around the outer peripheral wall of the cable 6 to be laid. The slider 11 can slide along the first cavity. When the slider 11 is inside the first cavity, it remains in a closed state due to the close contact between the slider 11 and the wall of the first cavity, and moves forward with the tension of the traction rope.

[0034] Continue to refer to Figure 6 In this embodiment, the slide rail unit 11 also includes a fixing plate 1013. The fixing plate 1013 is disposed at the bottom end of the housing 1011. The fixing plate 1013 is fastened to the steel purlin 20 of the overhead pipeline 2 by a locking member 1015. This arrangement ensures that the cable slide rail 10 does not shift during the traction process of the cable 6 to be laid.

[0035] Continue to refer to Figure 2 , Figure 3 as well as Figure 5 In this embodiment, the slider 11 includes a first block 111 and a second block 112. The first block 111 has a first arc-shaped through groove, and the second block 112 has a second arc-shaped through groove. The side of the second block 112 with the second arc-shaped through groove is attached to the side of the first block 111 with the first arc-shaped through groove. The first block 111 is rotatably connected to the second block 112 by a hinge. The first arc-shaped through groove and the second arc-shaped through groove are correspondingly arranged and together form a rotating cavity 114, through which the cable 6 to be laid is inserted. The bottom ends of the first block 111 and the second block 112 are provided with racks 113 that mesh with gears 1014. By setting racks 113, friction is reduced during the sliding of the slider 11, and energy loss can be reduced with higher transmission efficiency, so as to achieve the purpose of fast and labor-saving laying of cables on high-altitude pipe racks.

[0036] It should be noted that the structures of the first block 111 and the second block 112 can be the same or different. In this embodiment, the structures of the first block 111 and the second block 112 are basically the same.

[0037] During use, the second block 112 is opened, the cable 6 to be laid is inserted into the first arc-shaped through groove, and then the second block 112 is closed so that the slider 11 wraps around the outer peripheral wall of the cable 6 to be laid.

[0038] It should be noted that various specifications of rotary through-cavities 114 can be manufactured according to the common cable outer diameter.

[0039] The housing 1011, cover plate 1012 and fixing plate 1013 are all made of metal; the slider 11 is made of metal.

[0040] Furthermore, in this embodiment, an anti-slip layer is adhered to the inner peripheral wall of the rotating cavity. The cable 6 to be laid is used to pass through the rotating cavity 114, and the outer peripheral wall of the cable 6 to be laid is in contact with the anti-slip layer. By setting the anti-slip layer, the cable 6 to be laid can be firmly fixed to prevent slippage during the traction process of the cable 6 to be laid, and the outer sheath of the cable 6 to be laid can be protected to prevent the slider 11 from damaging the outer sheath of the cable 6 to be laid.

[0041] Continue to refer to Figure 1 and Figure 4 In this embodiment, the cable slide 10 also includes a turning elbow 102, which is disposed between two slide units 11 and is connected to the slide unit 11.

[0042] Furthermore, in this embodiment, the steering elbow 102 includes a housing, an end cap, and a plurality of rotating gears 1022. The end cap is disposed on the upper end of the housing and is rotatably connected to the housing. The housing surrounds a receiving cavity, which is divided into a first chamber and a second chamber. The first chamber and the second chamber are connected. The plurality of rotating gears 1022 are disposed in the second chamber and are spaced apart along the extension direction of the second chamber. The plurality of rotating gears 1022 are all capable of rotating relative to the housing. The plurality of first cavities are connected to the first chamber and together form a sliding cavity. The plurality of second cavities are connected to the second chamber and together form a gear cavity.

[0043] During use, when the slider 115 is inside the slide cavity, it remains in a closed state due to the close contact between the slider 115 and the slide cavity wall. It moves forward with the pull of the traction rope. When the slider 115 leaves the slide cavity, it is no longer constrained by the slide cavity. Under the action of gravity, the slider 115 falls off the cable 68 to be laid and drops to the outlet of the slide cavity for recycling. The recycled slider is then taken to the beginning of the cable slide for continued use.

[0044] Furthermore, in this embodiment, multiple rollers 1021 are provided on the two opposite inner sidewalls of the first chamber, and the multiple rollers 1021 are all rotatable relative to the outer shell; by providing rollers 1021, it is convenient for the slider 11 to turn.

[0045] The end cap is rotatably connected to the outer casing via a hinge.

[0046] To prevent damage to the rollers 1021 on both sides, each slider 11 should not be made too long, and the ends of the slider 11 should be chamfered.

[0047] Furthermore, in this embodiment, the turning elbow 102 also includes a mounting plate 1023, which is disposed at the bottom of the housing and is fastened to the steel purlins 20 of the overhead pipeline 2 by fasteners.

[0048] It should be noted that both the locking component 1015 and the fasteners are bolts.

[0049] The usage process of the auxiliary device 1 for cable laying in the cable tray of the overhead pipeline provided in this embodiment is as follows: each section of slide rail unit 11 is placed on the steel purlin 20 of the overhead pipeline 2 according to the cable laying direction. When encountering a branch or turn of the overhead pipeline 2, a turning elbow 102 is installed according to the cable route. The turning elbow 102 is located between two slide rail units 11. The connecting lugs on the housing 1011 of two adjacent slide rail units 11 are connected by bolts. The cable slide rail 10 is leveled. After straightening, the fixing plate 1013 is fastened to the steel purlin 20 of the overhead pipeline 2 via the locking piece 1015; the traction rope of the winch 5 is extended along the cable slide 10, and the end of the traction rope is connected to the starting end of the cable to be laid 6 through the cable traction net sleeve. When the cable to be laid 6 is pulled to the starting end of the cable slide 10, a slider 11 is fitted on the outer peripheral wall of the cable to be laid 6. The slider 11 slides in the cable slide 10 under the tension of the traction rope; whenever the traction rope pulls the cable to be laid... After the cable 6 is moved forward a predetermined distance, a slider 11 is fitted onto the outer periphery of the cable 6 at the beginning of the cable slide 10. Multiple sliders 11 slide along the cable slide 10 within the cable slide 10 under the tension applied by the winch 5's traction rope to the cable 6 (the speed should not be too fast during cable laying; the winch switch should be turned off immediately if any abnormality occurs). After the cable 6 is laid in place, the clamp 41 is tightened onto the section of the cable 6 extending beyond the cable slide rail. On the surrounding wall; connect one end of the wire rope 42 to the pull ring, and the other end of the wire rope 42 to the hanging ring at the bottom of the column foot to fix the cable 6 to be laid and prevent the cable 6 to be laid from falling back; open the cover plate of the slide unit, starting from the end of the cable to be laid, take out the cable 6 to be laid section by section and place it in the cable tray 3. After each time the cable 6 to be laid is placed in the cable tray 3, tie and tag the cable 6 to be laid according to the specifications; after all the cables 6 to be laid have been transferred to the cable tray 3, install the cable tray cover plate.

[0050] The auxiliary device 1 for cable laying in cable trays on overhead pipelines provided in this application includes a cable slide 10 and multiple sliders 11. The cable slide 10 is fixed on the steel purlin 20 of the overhead pipeline 2 along the cable laying direction. The multiple sliders 11 are all sleeved on the outer peripheral wall of the cable 6 to be laid and are all located inside the cable slide 10.
