Description

Technical Field

[0001] This utility model belongs to the field of cable laying technology, specifically relating to a cable lifting and positioning device. Background Technology

[0002] Cable laying is a meticulously planned process involving the placement and installation of cables along a pre-surveyed and determined route to construct a complete cable line system. Among these operations, overhead and tunnel laying are particularly unique, both requiring the cables to be raised to a suitable location before being laid by specialized workers.

[0003] Currently, cable lifting and positioning operations mainly rely on large equipment such as conveyors and winches, and in some scenarios, even cranes or lifting platforms are required. However, in environments with limited space, the use of these large pieces of equipment is particularly inconvenient, and may even be impossible. Given this situation, there is an urgent need for a more convenient and flexible cable lifting and positioning device to adapt to various complex and changing operating environments.

[0006] Preferably, the second support plate is provided with a DC inductive sensor pointing towards the slider, and the slider is provided with metal triggers on both sides that can trigger the DC inductive sensor. The second servo motor is provided with a control module, and the control module is electrically connected to the DC inductive sensor.

[0007] Preferably, the cable lifting and positioning device includes: a third support plate for mounting the electric hoist, a fourth support plate arranged parallel to the third support plate and connected by a connecting column, the fourth support plate having a first bolt for detachable connection with the base, the base having a lifting ring, the fourth support plate having a hole, and the traction rope of the electric hoist passing through the hole and connecting to the lifting ring.

[0008] Preferably, the third support plate is provided with a plurality of second circular holes, and a metal block is provided on the other side of the third support plate, and a second bolt is provided on the metal block to connect with the second circular holes.

[0009] The beneficial effects of this utility model compared with the prior art are as follows:

[0010] This invention first connects one end of the cable to the winding shaft, then uses an electric hoist to lift the winding mechanism into position. Subsequently, the winding mechanism winds the cable onto the winding shaft, and the electric hoist lifts the winding mechanism into position. During the winding process, the cable rewinding mechanism evenly winds the cable onto the winding shaft, ensuring that the cable does not become tangled or knotted during the winding process. By controlling the reverse rotation of the first servo motor, the winding mechanism can be unwound. Attached Figure Description

[0015] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below to facilitate understanding by those skilled in the art.

[0016] Please see Figures 1 to 3This utility model provides a cable lifting and positioning device, including: an electric hoist 1, and a winding mechanism 2 pulled and lifted by the electric hoist 1; the winding mechanism 2 includes: a base 3, two first support plates 4 parallel to each other on the base 3, a winding shaft 5 supported by the first support plates 4, a first servo motor 6 connected to the winding shaft 5 through a first gear reducer, and a reciprocating wiring mechanism disposed on the first support plates 4 and parallel to the winding shaft 5; the reciprocating wiring mechanism includes: two sleeves 7 sleeved on the winding shaft 5 and fixedly connected to the first support plates 4 respectively, two second support plates 8 respectively connected to the sleeves 7, a slide rod 9 disposed between the second support plates 8, a lead screw 10 disposed parallel to the slide rod 9, a slider 11 slidably connected to the slide rod 9, a threaded hole 12 disposed on the slider 11 and cooperating with the lead screw 10, and a second servo motor 13 disposed on the second support plates 8 and driving the lead screw 10 to rotate; the slide rod 9 is provided with a first circular hole 14 pointing to the winding shaft 5. The first servo motor 6 drives the winding shaft 5 to rotate, which winds the cable. Reversing the first servo motor 6 unwinds the cable. The second servo motor 13 drives the lead screw 10 to rotate, causing the slider 11 to slide on the slide bar 9. The cable passes through the first circular hole 14 and connects to the winding shaft 5. This ensures that the cable is evenly wound on the winding shaft 5, preventing it from becoming tangled or knotted during the winding process. The reciprocating motion of the slider 11 can be achieved by controlling the forward and reverse rotation of the second servo motor 13.

[0017] The second support plate 8 is equipped with a DC inductive sensor 15 pointing towards the slider 11. Metal triggers 16, capable of activating the DC inductive sensor 15, are located on both sides of the slider 11. The second servo motor 13 is equipped with a control module, which is electrically connected to the DC inductive sensor 15. When the DC inductive sensor 15 senses the metal trigger 16, it sends a signal to the control module. The control module then controls the second servo motor 13 to reverse, causing the slider 11 to move in the opposite direction. Upon contact with another DC inductive sensor 15, the slider reverses again, thus achieving automated control of the reciprocating motion of the slider 11.

[0018] The cable lifting and positioning device includes: a third support plate 17 for mounting the electric hoist 1; a fourth support plate 18 parallel to the third support plate 17 and connected by a connecting column 19; a first bolt 20 on the fourth support plate 18 for detachable connection to the base 3; a lifting ring 23 on the base 3; and a hole on the fourth support plate 18 through which the traction rope of the electric hoist 1 passes and connects to the lifting ring 23. To prevent the winding mechanism 2 from swaying during operation, the first bolt 20 can be used to connect the fourth support plate 18 to the base 3 after the electric hoist 1 lifts the winding mechanism 2. The first bolt 20 can be removed when the winding mechanism 2 needs to be lowered. If the weight of the cable being lifted exceeds the power of the electric hoist 1, the winding mechanism 2 can be lowered first, the cable connected to the winding shaft can be connected, the electric hoist 1 can be used to lift the winding mechanism 2, and then the first bolt 20 can be used to connect the fourth support plate 18 to the base 3 before starting the first servo motor 6 to wind the cable.

[0019] The third support plate 17 has several second circular holes, and a metal block 21 is provided on the other side of the third support plate 17. The metal block 21 is provided with second bolts 22 that connect to the second circular holes. The metal block 21 is welded and fixed to the cable bracket to fix the electric hoist 1 in a suitable position.

[0020] The cable lifting and positioning device is also equipped with a wired switch for starting the first servo motor 6 and controlling the forward and reverse rotation of the servo motor, starting the second servo motor 13 at the same time as starting the first servo motor 6, and controlling the electric hoist 1.

[0021] When using the cable lifting and positioning device of this utility model:

[0022] First, weld the metal block 21 to the appropriate position, then install the third support plate 17 on the metal block 21. The winding mechanism 2 is located on the ground. Pass the end of the cable through the first round hole 14 and connect it to the winding shaft 5. Control the electric hoist 1 to raise the winding mechanism 2, connect and fix the base 3 to the fourth support plate 18, and start the first servo motor 6 and the second servo motor 13 to wind the cable onto the winding shaft 5. When the worker is laying the cable, control the first servo motor 6 to reverse and unwind it.

[0023] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
