In addition, described track 3 is provided with and has " U " shape sub-track 31 formations of spacing dorsad by two, one lateral surface 311 of described " U " shape sub-track 31 is fixedlyed connected with side frame 12, be connected by a firm plate 8 between described two " U " shape sub-track 31, make and more stablize firm linking between two " U " shape sub-track 31, the two ends of described pipe 014 are connected to the end face 313 of remaining silent of two " U " shape sub-track 31, described tourelle 4 comprises a plurality of guiding wheels, and each guiding wheels includes four directive wheels 41 that are on the same horizontal plane, the end of described underframe 22 and middle boxes 23 all is openend " U " shape outwardly, and each end of described underframe 22 and middle boxes 23 is respectively equipped with at least one guiding wheels, two directive wheels 41 in these guiding wheels (can make the front and back of underframe 22 and middle boxes 23 keep balance) are located in the closed end of " U " shape end and are sliding surface with another lateral surface 312 of " U " shape sub-track 31, and other two directive wheels 41 in these guiding wheels (can make underframe 22 and middle boxes 23 about keep balance) are located at the medial surface of " U " shape end respectively and are sliding surface with the end face 313 of remaining silent of " U " shape sub-track 31.In the present embodiment, the both ends of described underframe 22 are provided with a falling-proof safety device 01 respectively, and the both ends of described underframe 22 are provided with guiding wheels parallel about in the of two respectively, and each end of middle boxes 23 is respectively equipped with guiding wheels.

The operating principle of falling-proof safety device 01 in the utility model: when wire rope 7 operate as normal, wire rope 7 has a pulling force that makes progress by wirerope axis 013 to the end that anti-fall off the hook 012 is provided with holding section 0121, and anti-fall off the hook 012 is in order to obtain equilibrium of forces, and its end that is connected with spring 011 produces a downward power and makes that spring 011 is drawn high; When fracture takes place in wire rope 7, originally wire rope 7 is applied to the disappearing to upper pulling force an of end that anti-fall off the hook 012 is provided with holding section 0121 by wirerope axis 013, and the also corresponding disappearance of downward power that the end that anti-fall off the hook 012 is connected with spring 011 applies spring 011, make spring 011 under self elastic deformation power effect, upwards compress one and recover deformation, and in this process, 011 pair of anti-fall off the hook 012 connected end of spring produces a pulling force that makes progress, make 3 the anti-fall off the hook 012 be articulated in underframe rotate counterclockwise around drive-connecting shaft, thereby hanging over, holding section 0121 card that makes anti-fall off the hook 012 is located on firm plate 10 pipes 014, and then stoped underframe 22 to fall downwards, to eliminate corresponding potential safety hazard.

The utility model is in the process of using: when needs open the door when promptly needing door body 2 risen, at first by the corresponding rising button on the operating control device, make electric block drive 5 and roll wire rope 7, it is the pulling force that wire rope 7 is subjected to upwards drawing high, indirectly, the underframe 22 of door body 2 is subjected to the effect that this pulling force upwards draws high too, thereby make directive wheel 41 on underframe 22 both ends on track 3 longitudinally upward to slippage, in the process of 22 liters of underframes, middle boxes 23 is vertically piled up under the effect of the power that underframe 22 makes progress and is risen, and in the process that middle boxes 23 rises, per two middle boxes, 23 outer main bodys 21 that are made of two sheets of flexible high-strength PVC lining are outwards piled up under airtight relatively space compression air effect, and then make a body 2 longitudinally folding and concentrate on doorframe 1 top frame 11 belows, thereby finish opening door operation; When needs are closed the door when promptly needing door body 2 descended, earlier by the corresponding decline button on the operating control device, make electric block drive 5 and remove the pulling force that wire rope 7 is made progress, make the underframe 22 and the middle boxes 23 of door body 2 make all slippages downwards longitudinally on track 3 of each directive wheel 41 under the effect of self gravitation, and the gravity of underframe 22 self produces downward pulling force to wire rope 7, thereby wire rope 7 is slowly descended along with the decline of underframe 22, and in the process of underframe 22 and middle boxes 23 declines, per two middle boxes, 23 outer main bodys 21 that are made of two sheets of flexible high-strength PVC lining are straightened under the action of gravity of underframe 22 and middle boxes 23 equally, thereby finish the pass door operation; If the situation of wire rope 7 unexpected fractures takes place in the process of opening door operation, anti-fall off the hook 012 rotates counterclockwise around drive-connecting shaft under the effect of spring 011 in the falling-proof safety device 01, thereby holding section 0121 card of anti-fall off the hook 012 is hung on the pipe 014, and then stoped underframe 22 to fall downwards.
