Description

Technical Field

[0001] This invention relates to the field of cable winding and unwinding devices, specifically to a cable winding and unwinding device with controllable tension and its control method. Background Technology

[0002] Cable reel-in / delivery devices are used to control the winding of cables. Cables are conductors consisting of one or more mutually insulated conductors and an outer insulating protective layer, laid underground, overhead, etc. Cables generally consist of three parts: a conductor, an insulation layer, and a protective layer. There are usually two types: power cables and control cables. Power cables are mainly used for the transmission and distribution of electrical energy; control cables are mainly used for measurement, protection, and control circuits. Cables are characterized by being internally energized and externally insulated.

[0003] For example, the authorized patent with publication number CN208802717U (Wire and Cable Reeling and Deployment Device for Convenient Field Operations) includes a support platform with an intermediate shaft for placing wires and cables. A support base plate for fixing the intermediate shaft is located on the side of the intermediate shaft near the platform. The platform and the support base plate are detachably connected. A fixing rod for fixing the wires and cables is located on the intermediate shaft. A sliding component for moving the fixing rod within a groove is also located on the intermediate shaft. A straightening mechanism for straightening the wires and cables is located on the support base plate near the intermediate shaft. A braking device for clamping the wires and cables is located on the support base plate near the straightening mechanism. A pushing device for moving the platform is located on the side of the platform near the ground. This facilitates the carrying of the wire and cable reeling device for field operations and is convenient for users.

[0004] The existing cable winding and unwinding devices described above cannot adjust the tension of the cable during the winding and unwinding process, making the cable winding and unwinding control unstable. They also cannot limit the cable during the winding process, making it easy for the cable to become misaligned, which affects the winding effect. Furthermore, they cannot straighten the cable during the winding process, and because the cable is easy to reset, it is not flat enough during the winding process. Summary of the Invention

[0005] The purpose of this invention is to provide a controllable tension cable winding and unwinding device and its control method, in order to solve the problems mentioned in the background art, such as the inability to adjust the tension of the cable during the winding and unwinding process, resulting in unstable cable winding and unwinding control, the inability to limit the cable during the winding process, the easy misalignment of the cable during the winding process, affecting the winding effect, the inability to straighten the cable during the winding process, and the easy reset of the cable, resulting in an uneven winding process.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a controllable tension cable take-up and release device, comprising a mounting plate, a cable take-up and release roller, a cable tensioning roller, a support frame, a support upright plate, a support base, a pressure roller, and a limiting sleeve.

[0013] Preferably, a second motor is provided inside the side ear, and the output shaft of the second motor is connected to the end of the cable tensioning roller.

[0014] A method for controlling the cable winding and unwinding with controllable tension includes the following steps: 1) The second motor drives the cable tensioning roller to rotate, while the first motor drives the cable take-up roller to rotate. The cable take-up roller is used to wind up the cable, and the cable tensioning roller is used to adjust the cable tension. 2) The cable being conveyed is limited by the limiting sleeve and locked and fixed by the locking teeth on its inner side. The third motor drives the drive gear to rotate, so that the drive gear and the driven gear are driven by the gear transmission, so that the driven gear drives the screw to rotate, so that the screw is connected to the guide hole screw transmission in the inner side of the guide plate, so that the guide plate drives the cable tensioning roller to adjust the height through the connecting rod, so that the cable tensioning roller adjusts the tension of the wound cable. 3) Adjust the angle of the mounting plate by using the electric actuator, adjust the angle of the hydraulic rod by using the mounting plate, adjust the angle of the pressure roller by using the hydraulic rod, and then use the pressure roller to press and straighten the cable wound on the cable take-up and unwinding roller.

[0016] The present invention is provided with a limiting sleeve, which is hinged to the top of the support frame. The limiting sleeve can limit the cable conveying and can lock and fix the cable through the locking teeth on its inner side, which can prevent the cable from deviating during the winding process and improve the stability and safety of cable winding.

[0017] The pressure roller of the present invention is controlled by a hydraulic rod, which is mounted on a mounting plate. The mounting plate and the end lug of the connecting plate are hinged, and an electric push rod is provided on the inner side of the hinge. The angle of the mounting plate can be adjusted by the push rod, so that the angle of the pressure roller can be adjusted. By setting the pressure roller and the cable take-up and untake-down roller directly opposite each other, the wound cable can be pressed and shaped, which can ensure the flatness and stability of the winding.
