The entire outer layer is covered with a highly insulating covering. During the on-site construction and production of cables, the cables need to be laid evenly, and during the construction process of cable laying, the laying of cables needs to be performed.

[0003] The existing automatic cable pay-off equipment adopts a split design, which is easy to carry during work and can adapt to cable reels of different sizes. The cable reel is lifted by a hydraulic cylinder, which reduces the labor intensity of workers. However, the cable reel needs to be turned over and placed on the support frame by manpower. Due to the heavy size of the cable reel, it is difficult to install. In addition, the existing pay-off device has low flexibility and needs to move with a vehicle. The device has a single usage state and cannot switch the pay-off mode, which makes it less practical. Summary of the invention

[0026] The frame 1 is a rectangular parallelepiped, and four universal wheels 11 are provided at the bottom to facilitate moving the present embodiment to a designated position.

[0027] The supporting assembly 3 includes two supporting frames 301, four rollers 302, two supporting plates 303 and two connecting rods 304. The two supporting frames 301 are symmetrically arranged on the left and right sides of the upper end surface of the frame 1. The symmetrical arrangement of the two supporting frames 301 is convenient for improving the stability of the placement of the cable reel. Each supporting frame 301 is respectively provided with three slots 311 for fixing the rollers 302 at intervals, and the slots 311 on the two supporting frames 301 are symmetrically arranged. The four rollers 302 are respectively symmetrically arranged in the slots 311. Two rollers 302 are placed on each supporting frame 301 to prevent the rollers 302 from moving when in use. Rollers 302 are placed in the slots 311 at the left ends of the two supporting frames 301, and the remaining two rollers 302 are placed in the slots 311 at different positions according to the diameter of the cable reel. By placing the rollers 302 in the slots 311 at different positions, cable reels of different diameters can be accommodated.

[0028] The right ends of the two support frames 301 are respectively hinged to the support plates 303, and the support plates 303 can rotate around the right ends of the support frames 301, so that the support plates 303 form a slope by rotating to facilitate the placement of the cable reel. The right ends of the support plates 303 are respectively turned to contact the ground, and the cable reel is pushed onto the two support frames 301 through the two support plates 303 and is located above the four rollers 302, thereby avoiding the need to flip the cable reel. Pushing the cable reel onto the support frames 301 through the rollers can save effort and facilitate installation. Two through holes are symmetrically provided at the lower parts of the two support frames 301, and two connecting rods 304 are parallel to penetrate the through holes and are connected between the two support frames 301, so that the two support frames 301 are balanced and stable. Fixed plates are provided at both ends of the two connecting rods 304, and the fixing plates are wrapped around the connecting rods 304 and the two ends of the fixing plates are fixed to the frame 1 by bolts, thereby fixing the connecting rods 304.

[0029] The driving assembly 4 includes a servo motor 401, a bevel gear set 402, a transmission shaft 403 and a fixing block 404. The transmission shaft 403 is connected between the two rollers 302 on the two support frames 301. The bevel gear set 402 is interference-connected to the transmission shaft 403 to change the output direction of the servo motor 401. The servo motor 401 is interference-connected to one end of the bevel gear set 402 and the servo motor 401 is fixed to the fixing block 404 by bolts to reduce the damage directly caused by the servo motor 401 to the frame 1. The fixing block 404 is The servo motor 401 is fixed to the upper end surface of the frame 1 by bolts. The bevel gear set 402 is driven to rotate by starting the servo motor 401. The rotation of the bevel gear set 402 drives the transmission shaft 403 to rotate. The rotation of the transmission shaft 403 drives the rollers 302 at both ends to rotate. The rotation of the roller 302 drives the cable drum above it to rotate, so that the cable drum actively releases the wire. The servo motor 401 is turned off, so that the cable drum is passively released through the inertial rotation of the roller 302, the transmission shaft 403 and the bevel gear set 402. The two release modes are convenient for improving the flexibility of the device.

[0030] A telescopic rod 5 is hinged on the left side of the left support frame 301 on the frame 1, and a fixed rod 51 for limiting the cable drum is inserted at the upper end of the telescopic rod 5. The cable drum is pushed onto the two support frames 301, the telescopic rod 5 is rotated to the height of the central axis of the cable drum, one end of the fixed rod 51 is passed through the inside of the central axis of the cable drum, and the other end is inserted into the upper end of the telescopic rod 5, so as to limit the cable drum and enable the cable drum to rotate in place above the four rollers 302.

[0031] The telescopic rod 5 is a hollow structure, and the fixed rod 51 is L-shaped, with its short end inserted into the upper end of the telescopic rod 5 and the long end passing through the inside of the central axis of the cable drum, and the diameter of the short end of the fixed rod 51 is consistent with the inner diameter of the upper end of the telescopic rod 5.

[0032] The left and right sides of the frame 1 are symmetrically fixed with three placement slots 2 for placing the fixing rods 51 by bolts. The placement slots 2 are used to store the fixing rods 51. The placement slots 2 are L-shaped, and the vertical end of the L-shape is arranged away from the frame 1, and the horizontal end is close to the frame 1 and is connected to a connecting plate below the horizontal end. The connecting plate is fixed to the frame 1 by bolts, so that the placement slots 2 are fixed to the frame 1. The L-shape and the connecting plate are integrated by welding. After the device is used, the fixing rod 51 is removed and placed in the placement slots 2, which can save the volume of the device and avoid the loss of the fixing rod 51.

[0033] A handle 11 is welded to the leftmost end of the upper end surface of the frame 1 to facilitate moving the frame 1.

[0034] The usage process of this embodiment is as follows:

[0035] First, place the two rollers 302 on the right side in the appropriate slots 311 according to the diameter of the cable drum, then rotate the two support plates 303 along the hinges so that the right ends of the support plates 303 are in contact with the ground to form two slopes, place blocking blocks on the left side of the two universal wheels 11 at the left end and on the right side of the two universal wheels 11 at the right end to fix the frame 1, then align the two wheels of the cable drum with the support plates 303 respectively, and push the cable drum so that the cable drum enters the support frame 301 along the support plates 303, and place the bottom of the cable drum above the four rollers 302, and rotate the telescopic rod 5 along the hinges so that The upper end of the telescopic rod 5 coincides with the central axis of the cable drum. One end of the fixed rod 51 is inserted through the inner side of the central axis of the cable drum, and the other end is inserted into the upper end of the telescopic rod 5. The cable drum is limited above the four rollers 302. At this time, the servo motor 401 is started. The servo motor 401 drives the transmission shaft 403 to rotate through the bevel gear set 402. The rotation of the transmission shaft 403 drives the two rollers 302 on both sides to rotate synchronously. The rotation of the rollers 302 drives the cable drum to rotate, so that the cable drum actively pays out the wire. When it is necessary to switch the pay-out mode, the servo motor 401 is turned off, and the cable is manually dragged to make the cable drum passively pay out the wire.
