In conclusion, the invention has the following beneficial effects:

1. when a cable drum on the transport vehicle needs to be installed on the seat frame, the blanking frame is firstly placed at the tail of the transport vehicle, meanwhile, the seat frame is placed at one side of the blanking frame, which is far away from the transport vehicle, and then the cable drum is rolled at the positions of the two right-angle triangular supports, so that two ends of the cable drum are respectively supported on the two damping rotating arms;

2. before the cable drum needs to roll down on the right-angle tripod, the connecting hooks at the end parts of the damping springs respectively hook the adjusting shafts in the connecting gaps, and at the moment, the damping springs simultaneously act to provide the maximum damping force, so that after the cable drum is supported on the damping rotating arm, the gravity of the cable drum is smaller than the damping force jointly generated by the damping springs, and the damping rotating arm cannot rotate downwards at the moment;

then gradually drawing out the adjusting shafts among the plurality of connecting sleeves, wherein each time the adjusting shafts pass through one connecting gap, the connecting hook where the connecting gap is located can be separated from the adjusting shafts, so that the damping force of one damping spring is lost; when the gravity of the cable reel is larger than the damping force jointly generated by the residual damping springs along with the gradual extraction of the adjusting shaft, the damping rotating arm can slowly rotate downwards, and then the cable reel on the damping rotating arm can fall onto the seat frame;

the effective damping force generated by the damping springs can be adjusted by pulling the adjusting shaft, so that the cable reel adjustable damping device can adapt to the falling of cable reels with different weights from a transport vehicle;

3. the limiting rings are arranged on the peripheral sides of the two ends of the connecting sleeve, so that the limiting rings can limit the connecting hooks in the connecting gap, and the connecting hooks can stably hook the adjusting shafts in the connecting gap;

4. the damping spring is in a tensioned state, so that a larger friction force exists between the connecting hook and the adjusting shaft, at the moment, an open slot is formed in the inner wall of the connecting hook, and a roller which is used for abutting against the adjusting shaft is rotationally connected in the open slot, so that the connecting hook and the adjusting shaft can generate rolling friction;

5. the U-shaped section of the damping rotating arm is convenient to adapt to the arc-shaped cable reel end, and the U-shaped section of the damping rotating arm can limit the cable reel end so as to avoid the deflection of the cable reel end on the damping rotating arm;

6. when the end part of the cable reel needs to fall on the track frame, the first guide wheel is rotatably connected at one end, far away from the blanking frame, of the track groove, the second guide wheel is rotatably connected at one end, close to the blanking frame, of the track groove, the V-shaped guide grooves are formed in the peripheral sides of the first guide wheel and the second guide wheel, the end part of the cable reel can be embedded into the guide grooves in the first guide wheel and the second guide wheel, when the cable reel is paid off, the end part of the cable reel can rotate between the first guide wheel and the second guide wheel, and smooth paying off of the cable reel can be facilitated finally;

7. the positioning block is arranged at the position corresponding to the damping rotating arm and on the lower side of the right-angle tripod, and the positioning block can be embedded into the track groove, so that the position between the track frame and the right-angle tripod is positioned, and the end part of the cable coil on the damping rotating arm can fall on the track frame accurately;

8. when the cable reel is paid off and needs to be taken off from the track frame, an operator steps on the pedal plate by feet, the pedal plate can drive the turnover arm at the moment, so that the turnover arm drives the second mounting shaft to move upwards, and then the second mounting shaft can lift the cable reel upwards, so that the cable reel rolls down towards one side of the blanking slope, and finally the cable reel can be conveniently and quickly taken off from the track frame;

9. when the cable drum rolls down from the unloading slope, the buffer rubber bulge arranged at the lower end of the unloading slope is utilized, the buffer rubber bulge can play a role in buffering, and the cable drum is prevented from rolling down too fast.
