[0032] The present invention also provides a conveying method of a cable conveyor for electric power construction:

[0033] Initially, the arc-shaped slider 29 is located at the rear side of the slotted hole; first, the electric cart 1 is controlled to move close to the cable drum so that the cable drum is located between the sliding clamps 17 on the front and rear sides, and then the drive motor Ⅱ21 is controlled to drive the screw rod Ⅱ22 to rotate to drive the mounting frame 16 to descend. The mounting frame 16 can drive the sliding clamp 17 and the rotating cone block 18 to descend. At the same time, the drive motor Ⅲ25 needs to be controlled to drive the screw rod Ⅲ26 to rotate to drive the lifting plate 24 and the sliding block 27 to descend, so that the sliding block 27 can descend synchronously with the rotating cone block 18 until the rotating cone blocks 18 on the front and rear sides are aligned with the through holes of the cable drum, and then the electric push rod 19 is controlled to drive the sliding clamps 17 on the front and rear sides to the direction close to the cable drum. The sliding clamp 17 can drive the rotating cone block 18 to be inserted into the through hole of the cable drum, so as to fix the position of the cable drum. The rotating cone block 18 can drive the sliding blocks 27 on the front and rear sides to move in the direction close to the cable drum. The sliding block 27 can slide on the lifting plate 24, and the sliding block 27 will not be separated from the lifting plate 24. Then the driving motor II 21 is controlled to drive the screw rod II 22 to reverse, so as to drive the mounting frame 16 to rise. The mounting frame 16 can drive the sliding clamp 17 and the rotating cone block 18 to rise. The rotating cone block 18 can lift the cable drum and separate the cable drum from the ground. At the same time, the driving motor III 25 needs to be controlled to drive the screw rod III 26 to reverse, so as to drive the lifting plate 24 and the sliding block 27 to rise, so that the sliding block 27 can rise synchronously with the rotating cone block 18, so that the weight of the cable drum can be supported by the mounting frame 16, the lifting plate 24 and the sliding block 27 to prevent the cable drum from falling; then the electric trolley 1 can be controlled to move to the front side of the bridge frame, and then the screw rod Ⅰ15 can be driven by the driving motor Ⅰ14 to rotate forward and reversely, which can drive the lifting and telescopic rod 3 and the positioning wheel 28 to lift and lower to adapt to the height of the bridge frame. At the same time, the rear end of the lifting and telescopic rod 3 can be pulled out backward to drive the rear positioning wheel 28 to move backward so that the positioning wheel 28 is stuck on the edge of the front side of the bridge frame top surface, and then the rear fastening bolt 13 can be loosened, and then the rear adjusting rod 301 can be moved forward and backward to drive the rear roller Ⅱ10 and the rear roller Ⅰ7 to move backward and forward. Move back and forth on the bridge to adjust the horizontal positions of the rear roller Ⅱ10 and the rear roller Ⅰ7 on the bridge, so that multiple cables can be neatly arranged on the bridge later. After adjustment, tighten the rear fastening bolt 13 to fix the position of the rear adjustment rod 301; then pull the upper roller Ⅱ10 and the rear roller Ⅱ10 away from the roller Ⅰ7 to drive the corresponding sliding plate 9 to move away from the mounting plate 6, so that the corresponding reset spring 12 is compressed, and then the cable end can be pulled out, and the cable end is passed between the upper roller Ⅱ10 and the upper roller Ⅰ7, and then through the wire frame 30, and then through the rear roller Ⅱ10 and the rear roller Ⅰ7 (such as Fig.11As shown), finally, fix the cable end at the starting point of the laying path, then release the upper roller Ⅱ10 and the rear roller Ⅱ10, the corresponding reset spring 12 will return to its original state, so as to drive the corresponding sliding plate 9 to move and reset in the direction close to the mounting plate 6, thereby driving the upper roller Ⅱ10 and the rear roller Ⅱ10 to be pulled apart in the direction close to the roller Ⅰ7, so that the roller Ⅱ10 and the roller Ⅰ7 can clamp the cable, and then start the upper servo motor 8 and the rear servo motor 8, the servo motor 8 can drive the corresponding roller Ⅰ7 to rotate, so as to continuously pull the cable out of the cable drum, the cable drum will rotate, thereby driving the rotating cone block 18 to rotate, without affecting the entire device. When other components are operating normally, the electric cart 1 can be controlled to move along the extension direction of the bridge, and the cable passes through the upper roller Ⅱ10 and the upper roller Ⅰ7, the wire frame 30, the rear roller Ⅱ10 and the rear roller Ⅰ7 in sequence, and can be directly laid at the designated position on the bridge. The roller 31 can guide and assist the transportation of the cable passing through the wire frame 30 to reduce the friction between the cable and the wire frame 30. At the same time, the positioning wheel 28 can roll along the edge of the front side of the bridge top surface to play a positioning role. Due to the limited control accuracy of the electric cart 1, the distance between the electric cart 1 and the bridge may deviate during the movement of the electric cart 1. At this time, the positioning wheel 28 can always be stuck at the edge of the front side of the top surface of the bridge frame to ensure that the relative position of the rear end of the adjusting rod 301 and the bridge frame will not change, and the free extension of the rear end of the lifting and telescopic rod 3 can make up for the distance deviation between the electric trolley 1 and the bridge frame, thereby ensuring the accuracy of cable laying; for bridge frames of different heights, the heights of the wire frame 30, the lifting and telescopic rod 3 and the adjusting rod 301 will also change accordingly, resulting in a change in the orientation between the upper roller Ⅱ10 and the rear roller Ⅱ10. At this time, the roller Ⅱ10 and the roller Ⅰ7 on the arc slide bar 5 will rotate due to the pressure generated when the cable is stretched and transported, so as to drive the arc slide bar 5 on the sliding rod 4 to rotate. Rotate so as to adapt to the use of bridges of different heights, that is: when the height of the bridge is low, the rear roller Ⅱ10 will be located behind and below the upper roller Ⅱ10, and at this time, the upper roller Ⅱ10 and the upper roller Ⅰ7 will be distributed up and down, so as to smoothly convey the cable to the wire frame 30; when the height of the bridge is high, the lifting telescopic rod 3 will rise to contact with the sliding rod 4, and drive the sliding rod 4 to rise synchronously, and the wire frame 30 will be located behind the upper roller Ⅱ10, and the rear roller Ⅱ10 will also be located behind the upper roller Ⅱ10, and the height difference between the three is not much, and at this time, the upper roller Ⅱ10 and the upper roller Ⅰ7 will be distributed front and back to ensure the normal transportation of the cable;Similarly, when the cable needs to be laid on the bridge frame at the front side of the electric cart 1, it is only necessary to pull the arc-shaped slider 29 forward to the frontmost side of the slotted hole, and then adjust the horizontal positions of the front roller Ⅱ10 and the front roller Ⅰ7 on the bridge frame, and then pass the cable end through the upper roller Ⅱ10 and the upper roller Ⅰ7, the wire frame 30, the front roller Ⅱ10 and the front roller Ⅰ7 in sequence, and the cable can be automatically laid on the bridge frame at the front side of the electric cart 1. ;

A method for conveying a cable conveyor for electric power construction according to any one of claims 4 to 6, characterized in that: The method comprises the following steps: firstly, controlling the electric trolley (1) to move close to the cable drum, then controlling the driving motor II (21) to drive the screw rod II (22) to rotate, so as to drive the rotating cone block (18) to descend to align with the through hole of the cable drum, then controlling the electric push rod (19) to drive the sliding clamps (17) on the front and rear sides to move close to the cable drum, the sliding clamps (17) can drive the rotating cone block (18) to insert into the through hole of the cable drum, so as to fix the position of the cable drum, and then controlling the driving motor II ( 21) driving the screw rod II (22) to rotate in reverse, so as to drive the rotating cone block (18) to rise and lift the cable drum, and then controlling the electric trolley (1) to move to the front side of the bridge frame, and then driving the screw rod I (15) to rotate forward and reversely through the driving motor I (14), so as to drive the lifting telescopic rod (3) and the positioning wheel (28) to move up and down to adapt to the height of the bridge frame, and at the same time, the rear end of the lifting telescopic rod (3) can be pulled backward to drive the positioning wheel (28) on the rear side to move backward, so that the positioning wheel (28) is stuck on the front side of the top of the bridge frame The cable end is then pulled out and passed through between the upper roller II (10) and the upper roller I (7), and then through the wire frame (30), and then through between the rear roller II (10) and the rear roller I (7). Finally, the cable end is fixed at the starting point of the laying path, and then the upper roller II (10) and the rear roller II (10) are released. The roller II (10) and the roller I (7) cooperate to clamp the cable, and then the servo motor (8) is started. The servo motor (8) can drive the roller I (7) to rotate so as to continuously pull the cable from the cable drum. At this time, the electric trolley (1) can be controlled to move along the extension direction of the bridge frame. The cable passes through the upper roller II (10) and the upper roller I (7), the wire frame (30), the rear roller II (10) and the rear roller I (7) in sequence, and can be directly laid at a designated position on the bridge frame.
