[0034] Combined with Figure 2 , Attachment Figure 7 , Attachment Figure 8 , Attachment Fig. 9 , Attachment Fig.10 and attached Fig.11 As shown, the bidirectional transmission mechanism 3 is arranged between the reel box 1 4 and the reel box 2 5, and the bidirectional transmission mechanism 3 includes a flameproof shield 31, a support frame 32 and a transmission assembly 33. The flameproof shield 31 is arranged on the outside of the support frame 32, and the transmission assembly 33 includes a support table 34 fixed on the inside of the support frame 32. A transmission sprocket 36 is rotatably provided on a fixed ring table 342 on one side of the support table 34. The transmission sprocket 36 cooperates with the sprocket at the end of the main transmission shaft 24 through chain transmission. A protection transmission mechanism 37 is arranged on both sides of the transmission sprocket 36. The protection transmission mechanism 37 includes a fixed transmission shaft 371 and a movable transmission shaft 372. The fixed transmission shaft 371 It is rotatably arranged in the through hole of the side plate of the support frame 32, one side of the fixed transmission shaft 371 is connected with the reel 1 43 and the reel 2 51, and the other side is provided with a slot 3711, and the two sides of the slot 3711 are inclined structures. The spline slot 3724 on one side of the movable transmission shaft 372 cooperates with the spline shaft 361 on both sides of the transmission sprocket 36, and the other side is provided with a limit plate 3721, and one side of the limit plate 3721 is provided with a clamping platform 3722 that cooperates with the clamping slot 3711, and the two sides of the clamping platform 3722 are inclined structures, and a spring 3723 is provided on the outside of the movable transmission shaft 372, and the two ends of the spring 3723 are respectively connected with the limit plate 3721 and the fixed ring platform 342.

[0035] Working principle of the bidirectional transmission mechanism 3: the driving mechanism 2 rotates the main transmission shaft 24, and the sprocket at the end of the main transmission shaft 24 cooperates with the transmission sprocket 36 through chain transmission, driving the transmission sprocket 36 to rotate, and the spline shaft 361 on both sides of the transmission sprocket 36 cooperates with the spline groove 3724 to drive the movable transmission shaft 372 to rotate, and the fixed transmission shaft 371 is driven to rotate through the cooperation of the card table 3722 and the card groove 3711, and the reel box 1 4 and the reel box 2 5 connected to the fixed transmission shaft 371 rotate accordingly, realizing the action of winding and releasing the cable of the reel box 1 4 and the reel box 2 5. When winding the cable, if the cable is obstructed, the rotation of the reel box 1 4 or the reel box 2 5 will be obstructed, and the fixed transmission shaft 371 and the reel box 1 4 and the reel box 2 5 will rotate. The movable transmission shaft 372 is still rotating under the drive of the driving mechanism 2, and the card table 3722 is disengaged from the card slot 3711. The limit plate 3721 moves toward the direction of the transmission sprocket 36, and the spring 3723 is compressed, so that the movable transmission shaft 372 is still rotating. When the potential energy of the spring 3723 pushes the limit plate 3721 to reset, the card table 3722 re-enters the card slot 3711 in the form of an impact, so that the fixed transmission shaft 371 has a certain rotation tendency, which will pull the cable to a certain extent. The cable will be re-reeled under slight obstruction. Under severe obstruction, the cable still does not move. At this time, the card table 3722 is disengaged from the card slot 3711 again to avoid damaging the cable during prolonged pulling.

[0036] Combined with Figure 8 , Attachment Fig. 9 , Attachment Fig.10 and attached Fig.11 As shown, the transmission assembly 33 also includes an adjustment structure 35, which includes an adjustment motor 351, a threaded column 352 and a slide 353. The adjustment motor 351 is fixed on the support platform 34, and a gear 3511 is provided at the output end of the adjustment motor 351. The threaded column 352 is rotatably arranged on the inner side of the support platform 34, and a gear 2 3521 meshing with the gear 3511 is provided at one end of the threaded column 352. The slide 353 is slidably arranged in a slide groove 341 on the inner side of the support platform 34, and a threaded hole matching with the threaded column 352 is provided on the slide 353. An arc plate 3531 is provided on one side of the slide 353 close to the protection transmission mechanism 37, and a roller 3532 is provided on one side of the arc plate 3531. The roller 3532 matches with a limit plate 3721, and a distance sensor or a vibration sensor is provided on one side of the limit plate 3721.

[0037] Working principle of adjustment structure 35: In order to adjust different cables under obstruction, so that the pulling force of the two-way transmission mechanism 3 on the cable through the reel is lower than the breaking pulling force of the cable, it is necessary to adjust the position of the limit plate 3721. During adjustment, the adjustment motor 351 drives the gear 1 3511 to rotate, and the gear 1 3511 and the gear 2 3521 are meshed and driven to rotate the threaded column 1 352, and the threaded column 1 352 cooperates with the threaded hole on the slide 353 to drive the slide 353 to move in the slide groove 341, and the limit plate 3721 is pushed through the arc plate 3531. The distance that the card table 3722 is inserted into the card slot 3711 is controlled, thereby controlling the difficulty of the card table 3722 being separated from the card slot 3711, and adjusting the contact area between the inclined surface of the card table 3722 and the inclined surface of the card slot 3711, thereby controlling the size of the static friction force, thereby preventing the same pulling force from damaging the thinner cable when winding different cables. The distance sensor or vibration sensor on one side of the limit plate 3721 is used to detect the number of times the card table 3722 is separated from the card slot 3711. After reaching the preset value, the main drive motor 21 stops working and sounds an alarm.

After opening the pressure cover 73, the reel 1 43 and the reel 2 51 can be lifted.

[0042] Combined with Figure 4 and attached Fig.14 As shown, the base 1 is provided with a cable arrangement mechanism 8 on one side of the cable entry groove 44, and the cable arrangement mechanism 8 includes a cable arrangement motor 81, a second gear box 82, a track plate 83, a positioning frame 84 and a cable arrangement frame 85.
