The working principle of the invention is as follows:
1) During normal work, lift cylinder 21 drives cylinder rod 22 and moves downwards, the effect that breaks away from head 32 of cylinder rod 22 tip through spacer pin 33 and break away from spring 34 sets up in breaking away from hole 311, cylinder rod 22's motion drives transmission slider 31 and slides along guide pillar 11, transmission slider 31's motion drives dodge gate 14 and moves, prevent that tong mechanism 5 at this moment continues downstream along dodge gate 14, prevent that tong 51 restricts the motion of turning block 43, prevent that spacing 432 of tong 51 on the restriction of spacing axle embrace the motion of block 42, make and embrace block 42 and can overcome the effect of embracing spring 414, and be restricted in the bottom of notch 411, prevent tong mechanism 5 and embrace mechanism 4 and do not take place the action, dodge gate 14 closes. Similarly, the lift cylinder 21 drives the cylinder rod 22 to open the movable door 14. Therefore, the movable door 14 can be driven to perform opening and closing movements by the driving of the lifting cylinder 21.
2) When danger occurs, for example, when the movable door 14 is driven to close by the lifting cylinder 21, a hand or other foreign matters are placed at the lower end of the movable door 14, the anti-pinch plate 51 firstly contacts with the hand, so that the anti-pinch plate 51 moves upwards relative to the movable door under the action of the hand and the floating connecting rod 52, the upward movement of the anti-pinch plate 51 loses the limitation on the rotating block 43, the pinching spring 414 jacks up the pinching block 42, the pinching block 42 jacks up the limiting shaft 432, so that the rotating block 43 rotates around the rotating shaft 431, meanwhile, as the movable door 14 moves downwards, the relative movement of the movable door 14 is added after the pinching block 42 is jacked up by the action of the spring, so that the pinching block 42 rapidly moves towards the opening of the notch 411 along the inclined plane 412 of the notch 411, the size of the notch 411 is smaller, the pinching block 42 is clamped between the notch 411 and the guide post 11, so that the motion of the pinching block 42 can limit the movement of the sliding block 41 to stop, and the stop the movement of the movable door 14; at this time, the lifting cylinder 21 continues to drive the cylinder rod 22 to move, and the movable door 14 is restricted by the clasping block 42 to stop moving, so that the transmission slide block 31 stops moving, the separation head 32 at the end part of the cylinder rod 22 is separated from the separation hole 311 by overcoming the acting force of the limit pin 33 and the separation spring 34, and the power of the lifting cylinder 21 is cut off from the power between the movable doors 14. When the movable door 14 stops moving, the self-locking of the self-locking mechanism and the power cut-off of the transmission mechanism are simultaneously completed.
3) Automatic reset, after the trouble was clear away, lift cylinder 21 drives cylinder rod 22 upwards to move, make break away from head 32 and overcome the effort that breaks away from spring 34 and spacer pin 33 and reset again to breaking away from in the hole 31, cylinder rod 22 drives transmission slider 31 upwards with dodge gate 14 and moves, make dodge gate 14 open, after dodge gate 14 upwards moved certain distance, the motion of reset pin 12 and driving block 511, make the motion of anti-pinch plate 51 restricted, make the floating mechanism reset, when dodge gate 14 was opened completely, just make anti-pinch plate 51 reply initial position through the effect of reset pin 12, driving block 511 plays limiting displacement to rotating block 43 again, make spacing axle 432 can overcome the effort of embracing tightly spring 414, will embrace tightly the bottom that block 42 restricts at sliding block 41, realize the automatic reset of driving mechanism, embrace mechanism and floating mechanism.
The above embodiments are only preferred embodiments of the present invention, and are not intended to limit the present invention in any way, and other variations and modifications may be made without departing from the scope of the claims.
