Lifting body in this embodiment; Place in the blower fan transportation erecting stage; This lifting body has three force transferring parts, and the force transferring part that the force transferring part that is positioned at top layer is bearing plate 2, be positioned at bottom is a underframe 1, and the force transferring part central frame between the two; Also have four groups of pushing tow unit groups, acting as of force transferring part transmitted the jacking force of pushing tow unit successively.During lifting body work, blower fan is embraced act mechanism and is positioned on the bearing plate 2.Underframe 1 guarantees promptly that for being positioned at the turret mount that platform is inner and captive joint with the pivoting support inner ring underframe 1 can rotate, and pivoting support shown in Figure 2 places on the tank top plate 8 in the platform, and the outer ring of pivoting support and tank top plate 8 are fixing; Bearing plate 2 is the part of platform deck, is mechano decking, when bearing plate 2 descends; Concordant with other one deck section, during rising, mechano decking is higher than other partial decks; The blower fan of being convenient to be positioned on the bearing plate 2 is embraced when lifting mechanism's revolution, with other component interferences, can not understand with reference to Fig. 1.
The structure of four groups of pushing tow unit groups is in full accord shown in Fig. 3, all has two pushing tow unit, i.e. one-level pushing tow unit 41 and secondary pushing tow unit 42.Can be with reference to figure 5, Fig. 5 is the structural representation of one-level pushing tow unit, secondary pushing tow unit 42 is identical with one-level pushing tow unit 41 structures.One-level pushing tow unit 41 has boxed rod 411, lower link 412 and the middle push rod 413 that an end is articulated in a place.
In conjunction with Fig. 6 to Fig. 8, Fig. 6 is the structural representation of central frame among Fig. 2; Fig. 7 is the structural representation of underframe among Fig. 2; Fig. 8 is the structural representation of bearing plate among Fig. 2.
The lower end of four one-level pushing tow unit 41 lower links 411 four jiaos four hinged groove 1a, 1b, 1a ' and 1b ' of hinged underframe 1 respectively in four groups of pushing tow unit groups, the upper end of boxed rod 412 is four hinged groove 3c, 3d, 3c ' and the 3d ' at the inboard place of hinged central frame 3 upper ends four drift angles respectively; Four hinged groove 3a, 3b, 3a ' and the 3b ' in the outside, hinged central frame 3 four base angles, lower end of four secondary pushing tow unit 42 lower links; Four hinged groove 2a, 2b, 2a ' and 2b ' that the hinged bearing plate in the upper end of boxed rod is 2 four jiaos, then one-level pushing tow unit 41 is supported in bearing plate 2 on the underframe 1 with secondary pushing tow unit 42.Can be known that by Fig. 3 the boxed rod 411 of one-level pushing tow unit 41 forms two connecting rod mechanisms with lower link 412, secondary pushing tow unit 42 is consistent with its structure; When one-level pushing tow unit 41 is in reset mode with secondary pushing tow unit 42, have preset angle between boxed rod and the lower link, promptly the distance between boxed rod upper end and the lower link lower end is shorter; When the pushing tow unit is in running order; Boxed rod and lower link rotate gradually, and when the two was in straight configuration, promptly the two angle was 180 when spending; Distance between boxed rod upper end and the lower link lower end is the longest, and then the rise or the decline that can realize bearing plate 2 to resetting is stretched or stretched to being reset to of two pushing tow whole units.
In this specific embodiment; Each is organized, and one-level pushing tow unit 41 all has middle push rod (having middle push rod 413 like one-level pushing tow unit 41) with secondary pushing tow unit 42 in the pushing tow unit group; Push rods all are connected with thruster in the middle of two, and push rod 413 moves and then the bending of drive one-level pushing tow unit 41 and secondary pushing tow unit 42 and stretching in the middle of being driven by thruster.Thruster can be a driving oil cylinder, such as, an end of driving oil cylinder is articulated in underframe 1, and the other end directly is connected with middle push rod 413, or the middle push rod of one-level pushing tow unit 41 and secondary pushing tow unit 42 all is connected synchronization action with driving oil cylinder.Then motion crooked and that stretch is done in one-level pushing tow unit 41 and secondary pushing tow unit 42 under the effect of thruster, thereby bearing plate 2 is risen or decline.
When four groups of pushing tow unit groups of lifting body are done the jacking action (boxed rod 411 and lower link 412 like one-level pushing tow unit 41 stretch); Under the effect of one-level pushing tow unit 41; Central frame 3 rising certain altitudes; Drive secondary pushing tow unit 42 rising corresponding height (lower link of secondary pushing tow unit 42 is articulated in central frame 3), and secondary pushing tow unit 42 is under the effect of thruster, certain altitude self also can raise.Therefore, the lift of secondary pushing tow unit 42 in the jacking course of action is the lift sum of self lift and one-level pushing tow unit 41, and the lift of secondary pushing tow unit 42 is the lift of bearing plate 2.
Principle can be known thus; Plural pushing tow unit can also be set in the pushing tow unit group, correspondingly increase the number of central frame 3, the number of central frame 3 should lack one than the number of pushing tow unit; And central frame 3 distributes along short transverse, is equipped with the pushing tow unit between the central frame 3.Be that central frame 3 is according to being set to first central frame, second central frame etc. by low paramount order; During connection; One-level pushing tow unit 41 boxed rods 411 are articulated in the underframe 1 and first central frame respectively with lower link 412; Secondary pushing tow unit 42 boxed rods and lower link are articulated in first central frame and second central frame respectively; Three grades of pushing tow unit boxed rods and lower link are articulated in second central frame and the 3rd central frame respectively, and the rest may be inferred, boxed rod and hinged respectively central frame and the bearing plate 2 that is in the extreme higher position of lower link until last pushing tow unit.The lift of then final bearing plate 2 be all pushing tow unit lifts and, formed multistage lifting body.Certainly, in view of the restriction of arrangement space, and be convenient to factor such as being provided with of central frame 3 and thruster, four groups of pushing tow unit groups all have two-stage pushing tow unit in this embodiment, can satisfy the demand of use, and are convenient to practical operation.
In addition; Underframe 1 among Fig. 7 has underframe body and four overhanging arms of captiveing joint with the pivoting support inner ring, and underframe 1 is used for being positioned at end, lower end pivotally attached four hinged groove 1a, 1b, 1a ' and 1b ' of four one-level pushing tow unit 41 lower links 412 free end of four overhanging arms.Underframe 1 structure of this structure can avoid its in turning course with other constructive interferences; In addition, rising arm outside it is variable section structure, and along the bearing of trend of overhanging arm, its cross section convergent when rising arm and underframe body Joint strenght outside guaranteeing, can reduce the volume and weight of underframe 1 as far as possible.
Can know by foregoing; With respect to prior art; Lifting body provided by the invention is multistage lifting body; Through setting the orderly connection of central frame 3 and pushing tows at different levels unit, the lift of lifting body is increased to the lift sum of all pushing tow unit step by step, thereby improved the whole lift of lifting body; And each pushing tow unit is driven by same thruster in the pushing tow unit group, under the situation that does not increase propulsive effort, has realized the increase of lift, has also guaranteed the synchronism between each pushing tow unit in the pushing tow unit group simultaneously, satisfies the durability requirements of jacking.
Need to prove that in this embodiment, be provided with four groups of pushing tow unit groups, and be symmetrical set, four groups of pushing tow unit components shown in Fig. 3 are distributed in foursquare four jiaos.In fact, two groups of pushing tow unit groups can realize the purpose of jacking.Four groups of pushing tow unit groups are set here are optimized technical scheme comparatively, can be more steadily jacking bearing plate 2 reliably, bear blower fan then and embrace the weight of lifting mechanism.
