Power box take-up and pay-off control system

Abstract

The invention discloses a power box take-up and pay-off control system, and relates to the technical field of power boxes. The take-up and pay-off control system comprises a control panel, a groove type lead screw winding displacement mechanism and a torque feedback control system, the groove type lead screw winding displacement mechanism is additionally arranged on the basis of a traditional power box, and meanwhile a torque sensor is installed in a reel and used for detecting the take-up and pay-off state and controlling power-assisted driving or electric driving of a motor; according to the take-up and pay-off control system, a manual take-up and pay-off mode is reserved, meanwhile, reliable jamming detection is added, the phenomena that a motor is burnt out or a power box body moves and topples over due to cable jamming are avoided, an electric take-up mode is added in the take-up and pay-off process of the power box, jamming detection is matched, manpower consumption is reduced, meanwhile, safety is improved, and the service life of the power box is prolonged. The power box take-up and pay-off system is additionally provided with a power-assisted pay-off mode, power is assisted only by pulling, work can be completed by only one person, and meanwhile manpower consumption is reduced.

Description

Technical field [0001] The present invention relates to the technical field power supply box, particularly the control system of a power retractable cable box. Background technique [0002] Currently, test and repair electrical field, due to the specific location of the work is not fixed, often need temporary wiring or extension cords to meet the power needs of test equipment. During use, always pull out the cable first hand, recovered after the end of the cable. This take-up process has the following problems in actual operation: [0003] 1, where the cable is long, time-consuming manual closing line, affecting the efficiency; [0004] 2, manual closing speed is difficult to maintain stable, easily lead to uneven distribution of the tightness of the cable on the reel, affecting the smooth discharge line; [0005] 3, actinomycetes, manually pull, because of friction between the cable must be fixed to one power supply box, one pull force, to successfully pull the cable extension s...

AI Technical Summary

Problems solved by technology

[0003] 1. In the case of a long cable, it takes time and effort to take up the cable manually, which affects work efficiency;

[0004] 2. It is difficult to maintain a stable manual take-up speed, which will easily lead to uneven distribution of the cables on the reel, which will affect the smooth pay-off;

[0006] 4. If the cable is blocked by a foreign object during electric take-up, it is easy to burn out the internal motor, or the power box is pulled to move, which increases the safety risk on site

[0007] In short, the current method of retracting and releasing wires used in mobile power boxes has greatly affected the work efficiency and work requirements on site, so it is urgent to upgrade this method of retracting and releasing wires to improve work efficiency and meet on-site needs
