Description

Technical Field

[0001] The present invention belongs to the technical field of cable laying racks, and in particular relates to an intelligent cable laying rack and a using method thereof. Background Art

[0002] With the rapid development of power construction, the application of large cross-section cable conductors is becoming increasingly widespread. Currently, conductors of 1440 square millimeters and 2500 square millimeters are routinely used in distribution network projects. This trend places higher requirements on the wire laying equipment: Traditional 3T and 5T-class wire laying racks are gradually phased out due to insufficient load capacity, and 8T, 10T, and even 25T-class large wire laying racks have become the mainstream. However, many safety and efficiency problems are exposed in the transportation and laying processes of existing equipment: 1. High risk of manual operation: The adjustment of the support body relies on manual operation, lacking automatic control. Operators need to be in close contact with the equipment, and the potential safety hazards to personnel are prominent. 2. Insufficient synchronization control: It is difficult to accurately ensure the lifting synchronization of the bilateral supports and the traction and laying speed synchronization, which easily leads to uneven stress on the conductor, resulting in equipment overturning or conductor damage. 3. Lag in digitalization level: The operation relies on manual experience judgment, lacking real-time data monitoring and visual feedback, and unable to scientifically evaluate the operation status. 4. Significant resource waste: In the scenario of replacing old cables, existing equipment cannot achieve the reuse of cables, causing double losses of social resources and economic benefits.

[0003] Therefore, an intelligent cable laying rack and a using method thereof are proposed. Summary of the Invention

[0004] The purpose of the present invention is to address the above problems and provide an intelligent cable laying rack and a using method thereof.

[0015] A usage method of an intelligent cable spreading rack, including the spreading rack, the specific steps are as follows: S1: Equipment transportation and base leveling. The intelligent cable spreading rack is towed to the operation site through the trailer frame. The operation control cabinet receives the remote control instructions, controls the jacking hydraulic cylinder to contract, makes the wheels contact the ground and moves the equipment to the designated position. Then the support hydraulic cylinder drives the support legs to vertically extend until the support legs completely touch the ground and bear the weight of the equipment, and the wheels leave the ground, completing the base leveling and fixing; S2: Low-level docking and installation of the cable reel. Operate the remote control to retract the telescopic hydraulic cylinder, driving the support rod to swing downward, lowering the cable reel to a low position close to the ground. Use a forklift to horizontally push the cable reel into the middle of the support cross-frame, enabling the drive pins on both sides of the cable reel to precisely engage with the rotating interfaces of the support rod to complete mechanical locking.

The bottoms of the two telescopic hydraulic cylinders 9 are rotatably connected to the top of the support cross-frame 1. The two support rods 8 and the two telescopic hydraulic cylinders 9 are distributed in a herringbone opposition. When the telescopic hydraulic cylinder 9 contracts, it drives the support rod 8 to swing downward, lowering the wire reel 5 to a low position. When the telescopic hydraulic cylinder 9 extends, it drives the support rod 8 to swing upward, placing the wire reel 5 at a high position.

[0028] A rotating mechanism is provided in the middle of the wire reel 5, and the rotating mechanism is arranged on one side of the hydraulic telescopic mechanism. The rotating mechanism includes a driving shaft 10 fixedly provided in the middle of the wire reel 5, and both ends of the driving shaft 10 are respectively rotatably connected to the rod walls of the two support rods 8.

Subsequently, the supporting hydraulic cylinder 6 drives the supporting legs 7 to extend and touch the ground to level the base. The wheels 2 are lifted off the ground to ensure stability. Then, the telescopic hydraulic cylinder 9 contracts to drive the supporting rod 8 to swing downward, lowering the cable reel 5 to a low position. The forklift pushes the cable reel into the supporting cross-frame 1 and locks it with the supporting rod 8 through the driving pin 21. After that, the telescopic hydraulic cylinder 9 extends to lift the cable reel to the working height and fixes it with a hydraulic lock. During laying, by setting parameters through the operation control cabinet 18, the hydraulic pump station 19 supplies oil to the hydraulic motor 11. After the speed is reduced and the torque is increased by the speed reducer 12, the drive shaft 10 drives the cable reel 5 to rotate. The wire arranging hydraulic cylinder 16 drives the slider 15 to drive the wire arranging wheel 17 to move synchronously to achieve uniform wire arranging. At the same time, the tension sensor continuously monitors the cable tension and feeds it back to the PLC controller inside the operation control cabinet 18. The rotational speed of the hydraulic motor 11 and the braking torque of the brake 13 are adjusted through the PID algorithm to ensure that the tension is stable within the range of ±3% of the set value. In case of sudden power failure or overload, the accumulator drives the brake 13 to lock the drive shaft 10 within 0.3 seconds. The operation control cabinet 18 triggers an audible and visual alarm and displays a fault code. After the operation is completed, the telescopic hydraulic cylinder 9 contracts to lower the cable reel. The forklift unloads the empty reel. The supporting legs 7 retract. The lifting hydraulic cylinder 20 extends to make the wheels 2 touch the ground. The equipment resumes the transportation state. Finally, the operator resets the system and conducts inspection and maintenance.
