The beneficial effects of the utility model are as follows: place the two base plates on both sides of the bobbin respectively, and align the arc grooves on the slider with the shaft ends at both ends of the bobbin, and then drive the slider on the two vertical plates through the driving device. The center slides upwards, so the bobbin is lifted up, and finally rises until the bobbin is off the ground and can be rotated. During the upward movement of the bobbin, the support rod is pulled by the belt to follow the upward movement. When the bobbin rotates, the magnetic powder brakes until the bobbin rotates through the belt to produce a certain damping effect, which prevents the free rotation of the bobbin. Because it is installed on both sides of the bobbin, it can also facilitate construction in a space with narrow terrain and improve work efficiency.

Detailed ways

Below in conjunction with accompanying drawing 1, accompanying drawing 2 the utility model is described further.

The power cable pay-off device includes two base plates 1, vertically installed vertical plates 2 on each base plate 1 and parallel to each other, chute 6 respectively arranged on each vertical plate 2, sliding installation The slider 5 between two vertical plates 2, the pole 8 slidably installed in the chute 6 of a vertical plate 2, the magnetic powder brake 9 installed on the end of the pole 8 and the magnetic powder brake 9 installed on the rotating shaft Pulley Ⅰ 14, the left and right ends of the slider 5 are respectively provided with clamping blocks 7, the clamping blocks 7 are stuck in the chute 6, and the slider 5 is provided with a semicircular arc groove, the inner diameter of which is the same as that of the bobbin 3 The outer diameters of the shaft heads match, the spool 3 is fixed with a pulley II 15, the pulley I 14 and the pulley II 15 are connected by a belt 16, and the slider 5 moves up and down through a driving device. When in use, place the two base plates 1 on both sides of the spool 3 respectively, and align the arc grooves on the slider 5 with the shaft heads at both ends of the spool 3, and then drive the slider 5 on the two vertical plates through the driving device. 2, so that the spool 3 can be lifted upwards until the spool can be rotated off the ground. During the upward movement of the bobbin 3, the support rod 8 is pulled by the belt 16 to follow the upward movement. When the bobbin 3 rotates, the magnetic powder brakes to 9, and the rotation of the bobbin 3 is driven by the belt 16 to produce a certain damping effect, which prevents the bobbin from being free. Turning happens. Because it is installed on both sides of the bobbin 3, construction can also be facilitated in a space with narrow terrain, and work efficiency is improved.

The drive device can be of the following structure, which includes a screw rod 17 mounted between every two vertical plates 2 parallel to each other, a nut 18 mounted on the screw rod 17, a motor 4 fixed on a base plate 1, and a motor 4 installed vertically. On the shaft II 13 and the shaft I 10 on the output shaft of the motor 4, the two screw rods 17 are respectively screwed into the two sliders 5, and the shaft II 13 and the shaft I 10 are respectively equipped with a bevel gear I, two Bevel gears II are installed on the screw rods 17, and the bevel gears I and bevel gears II are meshed. Splines are respectively arranged at the head ends of the rotating shaft II 13 and the rotating shaft I 10, and splines are respectively arranged at both ends of a connecting shaft 12. II 13 and rotating shaft I 10 are connected to connecting shaft 12 through two spline sleeves 11 respectively. Before installation, remove the connecting shaft 12 and the spline sleeve 11 from the rotating shaft II 13 and rotating shaft I 10, then place the two base plates 1 on both sides of the bobbin 3, and make the two shaft ends of the bobbin 3 clamp on the slide After the arc groove in the block 5, connect the connecting shaft 12 with the rotating shaft II 13 and the rotating shaft I 10 through the spline sleeve 11.
