Automatic cable winding and unwinding device

Abstract

The invention provides an automatic cable winding and unwinding device. The automatic cable winding and unwinding device is characterized by comprising a cable roller, a driving device, a plate turnover mechanism, a wire leading device, a deviation correcting device and a control system, wherein the driving device drives the cable roller to rotate, the wire leading device is connected with the driven shaft in a sleeving mode, and the wire leading device can slide along the driven shaft; the deviation correcting device is arranged between a base and the wire leading device; and the control system is fixedly connected to the base, and the control system controls the length of cable conveying and start and stop of the deviation correcting device. At the construction site, a cable does not need to be dragged manually, a motor, and a driving shaft and the driven shaft in the driving device are adopted to automatically treat winding and unwinding of the cable, so that the heavy work of manually winding and unwinding the cable is replaced, and the cable is prevented from being damaged in the manual cable dragging process.

Problems solved by technology

[0002] In construction sites such as construction sites, due to the needs of production and construction, cables are usually used. When retracting and unwinding cables, it is necessary to first pass the cable rollers into the threading shafts of the pay-off equipment. Due to the weight and volume of the cable rollers and cables Large, it brings inconvenience to the on-site construction personnel, and it is inconvenient for the user to move. At the same time, the wire reel on the existing pay-off frame is not easy to disassemble. When the cable on the wire reel is used up, the roller frame needs to be replaced. It is laborious and laborious, reducing the work efficiency of on-site construction

Moreover, the rotating shafts on the existing roller frame, after being used for many times, have different degrees of bending deformation on the rotating shafts, and those with less bending deformation can be used again, but the wire roller jumps during the cable export process, which makes the output and transmission Line force and speed are unstable

[0003] Existing cables are usually coiled on a reel, and the reel is placed on a pay-off frame or a pay-off vehicle. During electric power construction, the cable is released from the reel by a pay-off frame or a pay-off vehicle, but for some cables , there will be a certain bending deformation when turning and pulling out from the cable reel, which is not convenient for installation and use, and it is easy to cause damage to the insulation protection layer of the cable after relying on pliers or other tools to straighten it

[0004] During the use of the existing pay-off rack, when the pulling force on the wire suddenly increases, it will cause the wire to become tense instantaneously. When the pulling force is greater than the tension of the wire itself, it is easy to cause damage to the wire core inside the wire and affect the quality of the wire. In use, at the same time, in the process of line defense, sometimes the speed of line defense will be slightly stopped, and the existing pay-off frame cannot be stopped at any time, resulting in the waste of wires caused by excessive release of wires, and affecting the line of defense of subsequent wires. In addition, the current Some pay-off racks do not have a locking function, and the wire wheel will rotate under the action of external force when it is not working, causing the wire to automatically roll out

In addition, there is no control over the required length of pay-off, resulting in excess cables being released and piled up, resulting in messy placement of cables, which is not conducive to on-site management of on-site construction

[0005] Once again, piles are easy to form during the rewinding and winding process of the pay-off rack equipment, and the utilization rate of the wire reel is not high, and when the piled up cables are untied for use again, due to the deformation of the inner core of the cable after storage and pileup, the used cables have A large number of bends and easy knotting will cause trouble to the repeated use of the cable (22), the operator will be laborious and laborious, and will damage the service life of the cable

[0006] The current cable defense equipment adopts the design method of the base frame and the rotating roller, which not only occupies an area of ​​the structure, but also has a heavy overall weight, which is not easy to carry on site
