Wherein, 1, frame is climbed in upper;2, frame is climbed in;3, frame is climbed in lower;4, lifting-up support;5, standard knot;6, piston cylinder;7, Oil cylinder support rod;8, oil cylinder attachment beam;9, interior to climb frame spandrel girder;10, main chord;11, oil cylinder otic placode;12, lifting-up support otic placode; 13, crossbeam;14, girder;15, idler wheel;16, jacking block;17, pawl is climbed.
Specific embodiment
Specific embodiment of the present utility model is described below, in order to facilitate understanding by those skilled in the art The utility model, it should be apparent that the utility model is not limited to the range of specific embodiment, to the common skill of the art For art personnel, if various change the attached claims limit and determine the utility model spirit and scope in, These variations are it will be apparent that all are created using the utility model of the utility model design in the column of protection.
According to one embodiment of the application, with reference to Fig. 1 and Fig. 2, jacking apparatus is climbed in the derrick crane of this programme, is wrapped Include be set in turn in upper on standard knot 5 from top to bottom climb frame 1, in climb frame 2 and lower interior climb frame 3;Climbed in upper frame 1, in It climbs frame 2 and lower interior frame 3 of climbing is all set in interior climb on frame spandrel girder 9.
Climbed in upper frame 1, in climb frame 2 and lower interior climb include two girders 14 and two crossbeams 13,14 He of girder on frame 3 Crossbeam 13 is disposed adjacent, and is connected by welding.
An idler wheel 15 is respectively set on the both ends of 13 inside of crossbeam, is set respectively on the both ends of 14 inside of girder The jacking block 16 cooperated with idler wheel 15 is set, four main chords 10 of standard knot 5 are caught between idler wheel 15 and jacking block 16, can use Guiding during jacking.
Except this, jacking block 16 is fixed on 13 inside of crossbeam by screw rod, can realize jacking block 16 and main chord by adjusting screw rod It is elastic between 10.
14 upper surface middle position of girder is respectively mounted an oil cylinder otic placode 11, installs piston cylinder 6, piston cylinder on oil cylinder otic placode 11 6 tops with climb pawl 17 and connect by pin shaft, during jacking, climb 17 claw clip of pawl on main chord 10, the promotion of piston cylinder 6, reality Now jack;After jacking, the release of pawl 17 is climbed, as shown in Figure 3.
A lifting-up support otic placode 12 is installed in 11 two sides of oil cylinder otic placode respectively, installs lifting-up support on lifting-up support otic placode 12 4;It inside climbs and fixes oil cylinder support rod 7 on frame spandrel girder 9 vertically, the two sides of oil cylinder support rod 7 are separately connected the oil being laterally arranged Cylinder attachment beam 8, two oil cylinder attachment beams 8 are sheathed on 6 two sides of piston cylinder, and the guiding of process is jacked for realizing piston cylinder 6, makes to live Plug cylinder 6 can accurate operation, avoid piston cylinder 6 shake.
Lifting-up support 4 is fixed on lifting-up support otic placode 12 by sliding bearing, after jacking reaches certain height, is needed By lifting-up support 4, inwardly rotation is caught in the marking time of standard knot 5, make its bear tower crane from heavy load;When the primary top of completion After rising operation, outward rotate.
According to one embodiment of the application, the workflow that jacking apparatus is climbed in this programme derrick crane is as follows:
The screw rod on jacking block 16 is adjusted, it is made not contact (release) between main chord 10,6 operation of piston cylinder jacking one Secondary, tower crane is climbed 1.5 meters upwards, make 5 lower end surface of tower-body standard section be slightly less than in climb 2 frame lower plane of frame, at this time stop jacking.
Inwardly rotation lifting-up support 4 is caught in lifting-up support 4 in standard knot 5 marks time, at this point, the retraction of application piston cylinder 6 makes The weight of entire tower crane fall in in climb on the lifting-up support 4 of 2 frame of frame, then the jacking block 16 climbed on the inside of frame in every set is held out against into tower Body main chord 10 unloads hoist, locks the screw rod of jacking block 16, completes to climb for the first time.
Tower crane climb it is primary after, it is nethermost it is lower in climb 3 frame of frame departing from interior climbing tower body, no longer work, interior climbed lower Frame 3 remove and be installed to topmost, as it is upper it is interior climb 1 frame of frame, in this way, 3 frame wheel of frame is climbed in upper, middle and lower during jacking Use is changed, can effectively reduce working strength, improves working efficiency, reduces operation difficulty.
Although being described in detail in conjunction with specific embodiment of the attached drawing to utility model, should not be construed as to this The restriction of the protection scope of patent.In range described by claims, those skilled in the art are without creative work The various modifications and deformation that can make still belong to the protection scope of this patent.
