The specific embodiment
The invention will be further described below in conjunction with drawings and Examples.
With reference to Fig. 1, Fig. 5, present embodiment comprises main couple 4, running mechanism, and both sides, beam 9 bottom are watered in placing of main couple 4 symmetries; Main couple 4 rear portions are provided with the support tourelle, and the middle part is by the 44 vertical hinged main truss suspension brackets 43 of shipping and reselling on another market; Main truss suspension bracket 43 fraising tops are provided with vertical slot 100 in the same way; Watered beam 9 upper front end and be horizontally installed with rear cross beam 1, the two ends of rear cross beam 1 connect an end of C shape arm 2 respectively, the other end of described C shape arm 2 vertically down, its end horizontal stretches in the vertical slot 100 of described main truss suspension bracket 43.
With reference to Fig. 2, Fig. 4.Support tourelle for being installed in the support cylinder 41 and the turning rolls 42 of described main couple 4 upper limbs successively.Support cylinder 41 has mechanical fuse cutout; Bracing frame 42 comprises supporting leg 421 and the balancing stand 422 hinged with supporting leg 421, and 2 rollers 423 are installed on the balancing stand 422 at least.
With reference to Fig. 1 and Fig. 3, running mechanism comprises two slides 11 that are connected downside symmetry interval, described rear cross beam 1 middle part, forward be anchored at and watered the traveling oil cylinder 13 that is connected described slideway 12 and described slide 11 on the beam 9 with described slide 11 corresponding two slideways 12 and two ends respectively, slideway 12 can be anchored at by anchor pole assembly 92 and water on the beam 9.
In addition, with reference to Fig. 1, the main couple front end also is connected with front beam 3, is arranged on the end basket platform 6 of main couple 4 bottoms, is suspended in described two limit nose girders 5 and at least two middle nose girder 5-1 that watered between beam 9 and the described front beam 3.
For guaranteeing the intensity of C shape arm 2, carry out reinforcement to being installed with the smart screw-thread steel 21 of pricking between its top and the bottom.
To Fig. 5, the course of work of each cycle period of Hanging Basket comprises builds and moves forward two stages with reference to accompanying drawing 1.Concrete construction process is: when building, nose girder 5 bears the concrete load and Hanging Basket deadweight that template 8 is transmitted with end basket platform 6, and by suspension rod Load Transfer to front beam 3 is reached on the casting beams section 9.Front beam 3 is given main couple 4 front fulcrums with Load Transfer, and main couple 4 utilizes articulated structure to give main truss suspension bracket 43 and rear fulcrum with the suffered Load Transfer of front fulcrum.The load of rear fulcrum is directly passed to casting beams section 9.Main truss suspension bracket 43 is given rear cross beam 1 by suspension rod with Load Transfer, and rear cross beam 1 is given casting beams section 9 by slide 11 with Load Transfer.When Hanging Basket is built, on the beam section of having built, carry out the pre-colligation operation of reinforcing cage of next beam section.
Build when finishing reach, shrink support cylinder 41, main couple 4 is rotated around stub axle 44 finish the demoulding, trailing wheel 42 is contacted with the frange plate concrete, pine removes all anchoring suspension rods, and main couple 4 drops on the C type hook 2, prepares to begin reach.Under the effect of pipe bending cylinder 13, slide 11 drives whole Hanging Basket reach in track 12 slides forwards, utilizes the track 12 and the gap of slide 11 can realize the guiding of Hanging Basket, and it is simple in structure effectively.When the Hanging Basket reach puts in place, utilize hydraulic jack jacking Hanging Basket that main truss suspension bracket 43 is separated with C type hook 2, anchoring suspension rod 71, support cylinder 41 extends and contacts with edge of a wing plate-girder face, support cylinder 41 continues jacking makes the Hanging Basket absolute altitude arrive the job requirement state, while trailing wheel 42 separates no longer stressed with the beam face, the mechanical self-latching nut of locking support cylinder 41 is prepared to begin to build.Because this moment, Hanging Basket top construction space was enough, and the reinforcing cage colligation that this beam section need have been used when building a beam section finishes, and therefore need not on-the-spot colligation and organizes upright reinforcing cage, only needs directly mould to be gone in the reinforcing cage integral hoisting that colligation is good, upright internal mold of group and end mould begin to build then.
Be the preferred embodiments of the present invention only below, be not limited to the present invention, for a person skilled in the art, the present invention can have various changes and variation, and for example, the connected mode of main truss suspension bracket and C shape arm can also have other form of structure.In a word, within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
