Description

Technical Field

[0001] The present application relates to the field of cable reeling and unreeling equipment, and in particular to a cable laying and unreeling device. Background Art

[0002] A cable is made of several or several groups of wires twisted together. Each group of wires is insulated from each other and usually twisted around a central wire. The entire outside is covered with a highly insulating covering. The cable has the characteristics of internal power conduction and external insulation. Power cables are cables used to transmit and distribute electrical energy. Power cables are commonly used in urban underground power grids, power station lead-out lines, internal power supply for industrial and mining enterprises, and underwater transmission lines across rivers and seas.

[0003] The cable is often wound on a cable reel. When in use, the cable reel is mounted on a rotating shaft of a support for unwinding. When laying the cable, the cable on the cable reel needs to be pulled apart for laying. This is done by placing the cable reel on a pay-off rack.

[0004] With regard to the above-mentioned related technologies, the inventor believes that in order to facilitate the unfolding of the cables on the cable reel, the cable reel needs to be rotated, and thus the bottom end of the cable reel needs to be off the ground. When installing the cable reel, the cable reel needs to be raised manually. However, due to the heavy weight of the cable reel, the operation during the raising process is cumbersome, time-consuming and labor-intensive. Summary of the Invention

[0033] The following is combined with Figure 1-5 This application is described in further detail.

[0034] The present application embodiment discloses a cable laying and paying-out device. Figure 1 、 Figure 2 A cable laying and unwinding device includes a horizontally arranged rotating rod 1, a first supporting structure 2 is provided at one end of the rotating rod 1, and a second supporting structure 3 is provided at the other end of the rotating rod 1. The first supporting structure 2 and the second supporting structure 3 can drive the rotating rod 1 to rise and fall, and an expansion supporting structure 4 is provided on the outside of the rotating rod 1, which supports the inner side wall of the cable reel through the expansion supporting structure 4.

[0035] Reference Figure 2 、 Figure 3 The rotating rod 1 includes a horizontally arranged inner tube 11, and a first outer tube 12 is sleeved on one end of the inner tube 11 close to the first supporting structure. The first outer tube 12 is slidably connected to the inner tube 11 and the first outer tube 12 and the inner tube 11 are coaxially arranged, and the end of the inner tube 11 close to the second supporting structure 3 is sleeved on the second outer tube 13, and the second outer tube 13 is slidably connected to the inner tube 11 and the second outer tube 13 and the inner tube 11 are coaxially arranged.

[0036] One end of the second outer tube 13 facing away from the first outer tube 12 is fixedly connected to the first hydraulic cylinder 14. The hydraulic rod of the first hydraulic cylinder 14 extends from the inside of the first outer tube 12 and is slidably connected to the first outer tube 12. The hydraulic rod of the first hydraulic cylinder 14 is coaxially arranged with the first outer tube 12, and the hydraulic rod of the first hydraulic cylinder 14 completely penetrates the inner tube 11 and is relatively slidably connected. The hydraulic rod of the first hydraulic cylinder 14 is fixedly connected to the inner side wall of the second outer tube 13. The second outer tube 13 can be driven to move relative to each other in the horizontal direction through the first hydraulic cylinder 14.

[0037] A first baffle 111 is fixedly connected to the end of the inner tube 11 near the first outer tube 12, and a second baffle 121 is fixedly connected to the end of the first outer tube 12 near the inner tube 11. The first baffle 111 and the second baffle 121 are arranged opposite each other. A third baffle 112 is fixedly connected to the end of the inner tube 11 near the second outer tube 13, and a fourth baffle 131 is fixedly connected to the end of the second outer tube 13 near the inner tube 11. The third baffle 112 and the fourth baffle 131 are arranged opposite each other.

[0038] When the first hydraulic cylinder 14 pushes the second outer tube 13 to move toward the end away from the first outer tube 12, the fourth baffle 131 drives the third baffle 112 to move, thereby driving the inner tube 11 to move toward the end away from the first outer tube 12. Then, when the first baffle 111 and the second baffle 121 are in relative contact with each other, the inner tube 11 is limited, and passes through the first outer tube 12, the inner tube 11 and the second outer tube 13 from the axial position of the cable reel.

The hard portion 411 near one end of the first outer tube 12 is fixedly connected to the first outer tube 12, and the hard portion 411 near one end of the second outer tube 13 is fixedly connected to the second outer tube 13. When the second outer tube 13 extends from the outside of the inner tube 11, it drives the hard portion 411, which is fixed relative to the second outer tube 13, to move toward the side away from the first outer tube 12, thereby expanding the telescopic portion 412.

[0040] An air intake pipe 42 is horizontally arranged inside the inner tube 11. The air intake pipe 42 is a retractable bellows structure, and an air intake hole 421 is opened on the surface of the air intake pipe 42.

[0041] When the air pump 422 supplies air to the interior of the air intake pipe 42, the gas inside the air intake pipe 42 enters the interior of the airbag 41 through the air intake hole 421, thereby expanding the telescopic part 412 and pressing the airbag 41 against the interior of the cable reel to fix the cable reel.

[0042] Reference Figure 2 、 Figure 4The first supporting structure 2 includes a vertical first supporting rod 21, and a second hydraulic cylinder 22 is vertically arranged below the first supporting rod 21. The hydraulic rod of the second hydraulic cylinder 22 is fixedly connected to the first supporting rod 21, and the first supporting rod 21 is driven up and down by the second hydraulic cylinder 22. A first curved plate 23 is fixedly connected to the top of the first supporting rod 21. The first curved plate 23 is an arc structure, and the arc center of the first curved plate 23 is located above the first curved plate 23.

A rotating motor 26 is provided on the gear 25 to drive the gear 25 to rotate. The rotating motor 26 is fixedly connected to the first support rod 21. The rotating motor 26 drives the gear 25 to rotate, and then the gear 25 drives the gear ring 24 to rotate, so that the gear ring 24 drives the first outer tube 12 to rotate, and then drives the entire rotating rod 1 to rotate.

[0044] Reference Figure 2 、 Figure 5 The second supporting structure 3 includes a vertically arranged second supporting rod 31, and a third hydraulic cylinder 32 is vertically arranged below the second supporting rod 31. The hydraulic rod of the third hydraulic cylinder 32 is fixedly connected to the second supporting rod 31, and the second supporting rod 31 is driven by the third hydraulic cylinder 32 to move up and down, and a connecting block 33 is fixedly connected above the second supporting rod 31. The connecting block 33 is horizontally provided with a slot 331 relative to the position of the rotating rod 1, and the rotating rod 1 can extend into the interior of the slot 331 and rotate relatively.

[0045] The end of the rotating rod 1 close to the first curved plate 23 is located above the first curved plate 23, and the rotating rod 1 is rotatably connected to the first curved plate 23. When the rotating rod 1 is extended and unfolded, the end of the rotating rod 1 close to the connecting block 33 extends into the interior of the slot 331 and rotates relatively.

[0047] A locking ring groove 15 is provided at a position of the rotating rod 1 relative to the locking groove 333. The locking ring groove 15 is provided along the axial direction of the rotating rod 1, and the locking ring groove 15 is opposite to the locking block 334. When the vertical wall 3341 of the locking block 334 is vertically arranged, the end of the locking block 334 close to the rotating rod 1 can extend into the interior of the locking ring groove 15.

[0048] When the locking ring 332 is rotated so that the locking block 334 inside the locking groove 333 is located below the rotating rod 1, the locking block 334 is returned to the inside of the locking groove 333 by gravity, and then the rotating rod 1 is relatively disengaged from the slot 331.

[0049] The implementation principle of a cable laying and wire-releasing device in an embodiment of the present application is: the first hydraulic cylinder 14 drives the second outer tube 13 to move toward the side away from the first outer tube 12, and then the second outer tube 13 drives the inner tube 11 to move, thereby extending the rotating rod 1, and passing the rotating rod 1 through the inside of the cable reel, and supplying air to the inside of the air intake pipe 42 through the air pump 422, and the gas inside the air intake pipe 42 enters the inside of the air bag 41 from the air inlet hole 421, thereby driving the air bag 41 to expand and supporting the inside of the cable reel.

[0050] The second outer tube 13 on the rotating rod 1 extends into the interior of the slot 331 of the connecting block 33, so that the locking block 334 and the locking ring groove 15 are opposite each other, so that the locking block 334 enters the interior of the locking ring groove 15 under gravity, and the locking block 334 is located inside the locking ring groove 15 and rotates relatively, reducing the rotating rod 1 from escaping from the interior of the slot 331.
