A paying-off method of a cable paying-off device for power construction comprises the following steps:

firstly, inserting the roller shaft 13 into the cable roller, respectively sleeving the two ends of the roller shaft 13 into the collar posts 27, wherein one end of the collar posts 27, which is close to the fixing ring 26, faces the inside of the cable roller;

secondly, moving the two supporting mechanisms to enable two ends of the roller shaft 13 to be respectively inserted into the two rotary clamping grooves 19, adjusting the height positions of the rotary clamping grooves 19 by controlling the hydraulic jack 18, pushing the limiting bolt 21 to be inserted into the groove of the roller shaft 13 to be clamped and fixed, and installing the supporting plate 12 at the top through the clamping groove block 8 and the clamping column 9, so that the whole device is high in stability, convenient to disassemble and store, complete in function and convenient and fast to move;

thirdly, the crowbars 14 are respectively inserted into the two second prying blocks 24 to rotate, so that the pushing ring 23 moves towards the direction of the circular sleeve ring 22, the elastic sheets 25 are pushed to expand to clamp the interior of the cable roller, and the fixing of the roller shaft 13 and the cable roller is realized;

fourthly, controlling the two hydraulic jacks 18 to extend to enable the roll shaft 13 and the cable roll to be lifted, enabling the two hydraulic jacks to be moved simply through equipment, and after the positions are adjusted, inserting a crowbar 14 into the first prying block 3 to enable the supporting legs 4 to move to the lower part to be in contact with the ground to fix the whole device;

fifthly, during paying off, the clamping and fixing of the limiting bolt 21 on the roller shaft 13 is released, one end of the cable penetrates through the top of the paying off roller 30, the first motor 16 is controlled to be started, and the second rotating belt wheel 7 drives the first rotating belt wheel 5 and the rotating clamping groove 19 to rotate, so that the rotation of the roller shaft 13 and the cable roller is realized, the situation that the cable is pulled completely during paying off is avoided, labor is saved, and the possibility of cable damage is reduced;

sixthly, the cable wound on the cable roller moves left and right to touch the arc-shaped plate 36 when being paid off, so that the touch button 31 is triggered to be closed, and the second motor 38 is started;

seventhly, second motor 38 opens and makes first spur gear 33 drive second spur gear 34 and rotate, thereby make second belt 11 on the first regulation band pulley 10 rotate, drive connecting block 28 and remove towards the direction of touching, when cable and arc 36 separately, under torsional spring 41's effect, arc 36 touch button 31 separation, second motor 38 stall, the synchronization of paying out roller 30 and cable conductor has been realized, be convenient for improve unwrapping wire efficiency, reduce the friction of cable conductor, thereby protect the cable conductor surface can not the scratch.

The working principle is as follows: the roll shaft 13 is inserted into the cable roll, two ends of the roll shaft 13 are respectively sleeved into the collar posts 27, the two supporting mechanisms move in opposite directions to enable two ends of the roll shaft 13 to be respectively inserted into the two rotary clamping grooves 19, the height positions of the rotary clamping grooves 19 are adjusted through the hydraulic jack 18, the limiting bolts 21 are pushed to be inserted into the grooves of the roll shaft 13 to be clamped and fixed, the supporting plate 12 at the top is installed through the clamping groove blocks 8 and the clamping posts 9, the crowbar 14 is inserted into the second prying block 24 to rotate, the pushing ring 23 is pushed to move towards the direction of the circular collar 22, and therefore the elastic sheet 25 is compressed to be expanded to clamp the inside of the cable roll, and the roll shaft 13 and the cable roll are fixed; when paying off, the clamping fixation of the limiting bolt 21 on the roller shaft 13 is released, one end of a cable penetrates through the top of the paying-off roller 30, the first motor 16 is controlled to be started to enable the second self-rotating belt wheel 7 to drive the first self-rotating belt wheel 5 and the rotating clamping groove 19 to rotate, so that the roller shaft 13 and the cable roller rotate, the cable wound on the cable roller moves leftwards and rightwards and touches the arc-shaped plate 36 when paying off, the touch button 31 is triggered to be closed to enable the second motor 38 to be started, the first straight gear 33 drives the second straight gear 34 to rotate, so that the second belt 11 on the first adjusting belt wheel 10 rotates to drive the connecting block 28 to move towards the touch direction, when the cable is separated from the arc-shaped plate 36, the arc-shaped plate 36 touches the button 31 to separate under the action of the torsion spring 41, the second motor 38 stops rotating, the synchronization of the paying-off roller 30 and the cable is realized, and the paying-off efficiency is improved, the friction of the cable is reduced, so that the surface of the cable is protected from being scratched.

The electrical components appearing in the application document are externally connected with a power supply and a control switch when being paid off, the length of the elastic sheet 25 is determined according to the inner diameter of the cable roller, and the related circuit, the electronic components and the control module are all the prior art, and can be completely realized by the technical personnel in the field without extra remarks, and the protection content of the invention also does not relate to the improvement of software and a method.
