The specific embodiment
Describe concrete structure of the present invention in detail according to Fig. 1-6.This device is improved on the architecture basics of former " rack elevator ", locker 1 in keeping original device and the assembling magazine 2 and the left and right basic structure that initiatively connects pavilion 3 and parts such as left and right follower link 11 and left and right lifting controller thereof in it, the standby accumulator 12 that loads usefulness is set respectively in its left and right lifting controller housing 4.The equilibrant force of these two standby accumulators 12 can be identical with energy storage capacity, also can be different.Can load respectively, also can load simultaneously.The structure of this standby accumulator 12 can be selected extension spring according to actual needs for use; Also can select pneumatic cylinder or other energy storage damping buffering device for use.The standby accumulator 12 of present embodiment is preferentially selected extension spring for use.The one end can directly be hinged on the fixed axis 19 of drive connecting rod 3, also can be hinged on the fixed axis 19 that initiatively connects pavilion 3 by sliding sleeve 21, also can be hinged on drive connecting rod 3 central shafts 13 affixed interlock swivel plate or interlock rotating disc (end illustrates among the figure) on; The other end connects the hauling rope 9 that has block 15 by back shaft 10, the tensioning apparatus 14 that is packed in housing 4.Be to reduce frictional resistance to hauling rope 9, can be on back shaft 10 suit sliding sleeve 20.The telescopic fork pin 17 that left handle 8 and right handles 5 controls are arranged in the upper end that hauling rope 9 is positioned at block 15.The specification shape of this fork pin 17 should be determined according to the geometry of block 15.It is the bullet on plane that the geometry of present embodiment block 15 adopts the upper surface, is that plane, upper surface are the hatch frame on inclined-plane so the prong of fork pin 17 adopts the lower surface.Its left and right handle 8,5 is assembled on the housing 4 by guide type shoe 16, and control crank 8 or 5 pushes or pull out prong axially the stretching along guide type shoe 16 that can drive fork pin 17.When pushing handle 8 or 5, the prong on it stretches out to insert and is positioned at block 15 tops to hauling rope 9, loads standby accumulator 12; When draw-out handle 8 or 5, the block 15 on the hauling rope 9 is left in the prong withdrawal on it, unloads standby accumulator 12.Hauling rope 9 can adopt steel wire rope, highstrenghtpiston's rope, metal articulated link chain, chain etc.Tensioning apparatus 14 can adopt extension spring, also can adopt pneumatic cylinder or other energy storage stretcher, guarantees that hauling rope 9 is in tensioning state all the time.When drive connecting rod 3 when central shaft 13 rotates, the drive connecting rod fixed axis 19 of hinged standby accumulator 12 moves along the arc chute 18 of lifting controller housing 4.
