[0061] In order to improve the cable laying efficiency, when the cable is laid, the laying roller 2 is moved so that the sliding block 22 is aligned with the moving groove 11, and then the laying roller 2 is continuously moved; after the sliding block 22 is in contact with the inner wall of the moving groove 11, the electric push rod 31 is started, the electric push rod 31 pushes the supporting block 32 to move, when the supporting block 32 is in contact with the rotating rod 21, the rotating rod 21 and the laying roller 2 are pushed to move, so that the sliding block 22 slides along the inner wall of the communication groove 12; when the rotating rod 21 is in contact with the linkage block 73, the linkage block 73 is pushed to move away from the rotating rod 21, the movement of the linkage block 73 drives the vertical rod 71 and the horizontal rod 72 to move; when the horizontal rod 72 is in contact with the moving block 76, the moving block 76 is pushed to move towards the laying roller 2, the movement of the moving block 76 drives the moving rod 75 and the transmission gear 61 to move; when the transmission gear 61 abuts against the outer surface of the laying roller, the limiting spring 84 pushes the fixed ring 83 and the limiting rod 82 to move, so that the limiting rod 82 is inserted into the limiting groove 751, thereby reducing the possibility of movement of the moving rod 75 and the transmission gear 61; when the sliding block 22 is in contact with the inner wall of the communication groove 12, the electric push rod 31 is turned off, the driving motor 46 is started, the driving gear 47 is rotated, the rotation of the driving gear 47 drives the rotating gear 48 to rotate, so that the rotating rod 21 and the laying roller 2 are rotated; due to the fact that the transmission gear 61 is tightly attached to the outer surface of the laying roller, under the action of the friction force between the transmission gear 61 and the laying roller 2, the rotation of the laying roller 2 drives the transmission gear 61 to rotate, the rotation of the transmission gear 61 drives the rotating gear 62 to rotate, so that the rotating shaft 41 is rotated, the rotation of the rotating shaft 41 drives the rotating frame 42 to rotate, thereby the placing roller 43 is moved; when the placing roller 43 is in contact with the cable, the cable is moved; after the rotating frame 42 is in contact with the stop rod 56, the rotating frame 42 stops moving, at the same time, the rotating frame 42 pushes the trigger block 92 to move away from the rotating frame 42, the trigger block 92 makes the pulling rope 91 taut, thereby driving the fixed block 85 and the limiting rod 82 to move; after the limiting rod 82 is separated from the limiting groove 751, the stretching spring 93 pushes the moving block 76, the moving rod 75 and the transmission gear 61 to move away from the laying roller 2, thereby the transmission gear 61 is no longer in abutment with the laying roller 2; when the rotating frame 42 is about to be in contact with the stop rod 56, the electric push rod 31 is started, the movement of the electric push rod 31 drives the moving frame 55 and the pressing roller 53 to move towards the placing roller 43; after the rotating frame 42 stops moving, the cable is clamped between the pressing roller 53 and the placing roller 43 by pressing the cable and the placing roller 43 through the pressing roller 53, and then the servo motor 54 is started, the servo motor 54 drives the pressing roller 53 to rotate, so that the pressing roller 53 and the placing roller 43 are rotated, the cable is moved, thereby facilitating the cable laying.

[0062] The implementation principle of the cable pay-off device is as follows: after the pay-off roller 2 is installed, the driving mechanism 45 is started to drive the pay-off roller 2 to rotate, at the same time, the control mechanism 6 drives the rotating member 4 to rotate, so that the rotating member 4 drives the cable to the conveying mechanism 5, and then the conveying mechanism 5 is started to move the cable, thereby facilitating the pay-off of the cable.

[0064] S1, moving the pay-off roller 2, so that the sliding block 22 is in contact with the inner wall of the moving groove 11 and slides;

[0065] S2, after the sliding block 22 is in contact with the side wall of the moving groove 11 and stops moving, the support 3 is used to move the pay-off roller 2, so that the sliding block 22 slides along the inner wall of the communication groove 12;

[0066] S3, when the pay-off roller 2 stops moving, the driving mechanism 45 is started to drive the pay-off roller 2 to rotate, at the same time, the control mechanism 6 controls the rotating member 4 to rotate;
