An arc-shaped guide plate is arranged on the moving part, the arc-shaped guide plate is arranged around the self-adapting part, and is used for protecting and guiding the driving rope 47.

[0049] One end of the elastic part 52 is connected with the fixed limiting plate 541, the other end is connected with the moving limiting plate 551, when the driving rope 47 is continuously wound at the same position and the tension is large, the tension of the driving rope 47 is large, the self-adapting part is pulled to move in the driving direction, the moving plate 552 follows the movement, the elastic part 52 is compressed, of course, the elastic part 52 can also be arranged to be stretched, at this time, the driving rope 47 also moves in the driving direction, so as to leave the continuous winding position and is wound in the driving direction, when the elastic part 52 is released, the moving part is gradually reset, the self-adapting part is reset synchronously, the self-adapting module is arranged, continuous winding at the same position is avoided, and the driving rope 47 can be smoothly wound on the winding shaft and cannot vibrate.

The adjusting spring 64 is arranged between the pressing plate 63, when the air jet groove assembly 3 moves and encounters an obstacle to generate vibration, the tension of the drive rope 47 increases, which pulls the screw 62 and squeezes the adjusting spring 64, and after leaving the obstacle position, the adjusting spring 64 releases and restores the tension of the drive rope 47.

[0053] A first sensor 65 is arranged on the fixed frame 61, and a signal plate 66 is arranged on the pressing plate 63 away from the fixed frame 61, the first sensor 65 is signal connected with the control center of the quick freezing warehouse, when the air jet groove assembly 3 encounters an obstacle and cannot move, the screw shaft still keeps the winding action, which causes the drive rope 47 to pull the screw 62, thereby squeezing the adjusting spring 64, the first sensor 65 contacts the signal plate 66, the first sensor 65 sends a signal, and the control center of the quick freezing warehouse stops the defrosting device after receiving the signal, thereby effectively improving the stability and safety of operation.

[0054] The spring of the elastic member 52 is smaller in proportion than the adjusting spring 64, so that after the drive rope 47 continuously winds at the same position, the elastic member 52 is pulled first instead of the adjusting spring 64.

[0055] In order to protect the cable, a drag chain assembly 8 is arranged, and the drag chain assembly 8 is fixed on the top of the cold storage as a whole. The drag chain assembly 8 includes a drag chain groove 81, a drag chain 82 arranged in the drag chain groove 81, a roller 83 arranged on the drag chain groove 81, a connecting plate 84 arranged on the drag chain groove 81, the drag chain groove 81 is fixed on the cold storage through the connecting plate 84, the drag chain 82 and the roller 83 are connected, a roller groove is arranged on the drag chain groove 81, the roller groove is arranged on the outer side of the drag chain groove 81, and the roller 83 is arranged in the roller groove. During the movement of the air jet groove assembly 3, the drag chain moves in the drag chain groove, and is connected through the roller.

[0056] In order to monitor the movement state of the cable in real time, the self-adaptive driving device is further provided with a movement monitoring assembly 7, which can be arranged on the driving module 4 or the self-adaptive module 5. In this scheme, the movement monitoring assembly 7 is arranged on the self-adaptive base, and further, the movement monitoring assembly 7 is arranged between the two self-adaptive modules.

[0057] The movement monitoring assembly 7 comprises a movement base 71 fixed on the adaptive base, a movement top cover 72 movably arranged on the movement base 71, a second sensor 73 arranged between the movement base 71 and the movement top cover 72, and a force plate 74 arranged on the movement top cover 72. Further, a sliding groove is formed on the movement base 71, and movement side edges are arranged on both sides of the movement top cover 72, which are inserted into the sliding groove. When the air jet groove assembly 3 moves, the movement top cover 72 moves on the movement base 71.

[0058] In order to further avoid displacement of the second sensor 73, a sensor fixing frame 75 is arranged on the movement base 71, and the second sensor 73 is fixed on the sensor fixing frame 75. The force plate 74 is provided with two force plates 74 arranged in the driving direction. When the movement top cover 72 moves towards the driving direction, the force plate 74 will be in contact with the second sensor 73 to monitor the movement state of the cable in real time.

[0059] A movement support rod 76 is arranged on the movement top cover 72, and the movement monitoring assembly 7 and the drag chain assembly 8 are connected through the movement support rod 76, so as to facilitate the movement monitoring assembly 7 to monitor the state of the cable. Further, a drag chain movable shaft 85 is arranged at the end of the movement support rod 76, and the drag chain movable shaft 85 is connected with the drag chain 82. Because the length of the movement support rod 76 is relatively long, rollers are arranged to support. When the air jet groove assembly moves, the movement monitoring assembly 7 moves with it, driving the movement support rod 76 to move with it. The rollers 83 roll in the roller grooves, and the drag chain movable shaft 85 drives the drag chain 82 to move, so as to protect the related cables.

[0060] The working process of the air defrosting device is as follows:

[0061] The motor 43 is started to drive the transmission shaft 44 to rotate, and the driving bevel gear 45 rotates to synchronously and reversely drive the driven bevel gear 46 to rotate. The first winding shaft 41 and the second winding shaft 42 synchronously and reversely rotate. If the air jet groove assembly 3 moves to the side of the first winding shaft 41, the first winding shaft 41 winds the driving rope 47, and the second winding shaft 42 releases the driving rope 47. The air jet groove assembly 3 moves to the side of the first winding shaft 41.

[0062] In the winding process, since the relative position of the winding shaft and the adaptive pulley 531 does not change, the driving rope 47 can be continuously wound around the same position, and after the height of the winding is increased, the driving rope 47 will fall from this position to other positions of the winding shaft, which will cause vibration and affect the defrosting effect. Therefore, the adaptive pulley 531 is arranged to be movable towards the driving direction, and after the driving rope 47 is continuously wound around the same position, the tension of the driving rope 47 will be increased, and since the ratio of the adjusting spring 64 is greater than the spring of the elastic member 52, the driving rope 47 will pull the adaptive pulley 531 to move axially towards the winding shaft, so that the adaptive pulley and the corresponding winding shaft are relatively displaced, so as to stabilize the tension. At this time, the driving rope 47 will follow the movement and be wound around other positions of the winding shaft. At the same time, due to the action of the elastic member 52, when the driving rope is released, the adaptive pulley 531 will gradually reset, thereby driving the driving rope 47 to follow the movement. In the winding process, the driving rope 47 is always moved and wound around the winding shaft. If continuous winding occurs at the same position, the adaptive pulley 531 can also smoothly leave the continuous winding position, without causing vibration.

[0063] During the movement, the moving support rod 76 drives the drag chain 82 to follow the movement. During the movement, the force plate 74 is in contact with the second sensor 73 to monitor the state of the cable in real time.

[0064] If an obstacle appears during the movement, the motor 43 will not stop running immediately, and the winding shaft will still wind the driving rope 47. The driving rope 47 will pull the screw rod 62 to move, and the adjusting spring 64 will be compressed to adjust the vibration. If the obstacle cannot be moved, the adjusting spring 64 will be completely compressed, the first sensor 65 will be in contact with the signal plate 66, and the first sensor 65 will send a signal to the control center to stop the equipment.

[0065] The application mainly designs an adaptive driving device and an air defrosting equipment with the same. By arranging the winding shafts to rotate simultaneously and reversely, one driving rope is released while the other driving rope is wound, so as to realize movement. The adaptive module 5 is arranged to move towards the driving direction when the tension of the driving rope is increased due to continuous winding around the same position, so as to compress the elastic member 52 synchronously to adjust the tension, so that the driving rope can smoothly leave the winding position without causing vibration of the defrosting device, so as to realize stable operation. The movement monitoring assembly 7 is arranged to monitor the movement state of the cable, and the drag chain assembly 8 is arranged to protect the cable.
