Abstract
The invention discloses a lowering device for a jacking sleeve case. The lowering device is characterized by comprising an upper beam and a lower beam, wherein screw jacks are arranged between the upper and lower beams; an upper fulcrum nut is arranged on the upper beam; a lower fulcrum nut is arranged on the lower beam; and a finish rolled deformed steel bar boom is arranged between the upper and lower fulcrum nuts. Compared with the prior art, the lowering device has the advantages that the screw jacks are used as jacking equipment, a strong-strength finished deformed steel bar is used as the boom, and the finish rolled deformed steel bar nuts are matched as jacking and temporary fixing fulcrums, so that the aim of safely and stably lowering a steel hoisting box is fulfilled, and the lowering device is simple in structure and higher in stability and safety.
Description
[technical field]
The present invention relates to a kind of new structure that has end suspention steel box work progress to transfer for deep water, specifically relate to a kind of jacking casing downward putting device.
[background technology]
Along with China's expanding economy, the bridge constructions such as over strait, rivers grand bridge, bridge are also more and more.In bridge construction, the deep water cushion cap adopts the construction of steel box more at present.The steel box adopts after the fixing welding of the above temporary supporting of water surface assembly unit more and re-uses Chain block and transfer.The construction of large volume underwater support table is larger with steel box weight, and the stability of transferring, safety etc. require all higher, use this jacking casing downward putting device to address the above problem.
[summary of the invention]
The present invention is in order to solve above-mentioned deficiency, and a kind of jacking casing downward putting device is provided.
Above-mentioned purpose of the present invention realizes by following technical scheme: a kind of jacking casing downward putting device, it is characterized in that: it comprises top rail and lower transverse beam, be provided with jackscrew between top rail and lower transverse beam, top rail is provided with the fulcrum nut, lower transverse beam is provided with the lower fulcrum nut, is provided with the fining twisted steel suspension rod between upper fulcrum nut and lower fulcrum nut.
The present invention's advantage compared with prior art is: the present invention uses jackscrew as Lifting Equipment, high-strength fining twisted steel is as suspension rod, coordinate the fining twisted steel nut as jacking and temporary fixed fulcrum, reach the purpose that steel box safety and stability is transferred, simple in structure, stability, safety are all higher.
[description of drawings]
Fig. 1 is structural representation of the present invention.
In accompanying drawing, the 1-top rail; The 2-lower transverse beam; The upper fulcrum nut of 3-; The 4-jackscrew; 5-fining twisted steel suspension rod; 6-lower fulcrum nut.
[specific embodiment]
Below in conjunction with accompanying drawing, the present invention is described in further detail:
As shown in Figure 1, a kind of jacking casing downward putting device, it is characterized in that: it comprises top rail 1 and lower transverse beam 2, be provided with 50T jackscrew 4 between top rail 1 and lower transverse beam 2, top rail 1 is provided with fulcrum nut 3, lower transverse beam 2 is provided with lower fulcrum nut 6, is provided with Φ 32 fining twisted steel suspension rods 5 between upper fulcrum nut 3 and lower fulcrum nut 6.
Jacking casing downward putting device of the present invention,, completing lower transverse beam 2 after the installation on pile foundation steel casing is reinforced, install fining twisted steel suspension rod 5 and lower fulcrum nut 6, can realize that the interim suspention of casing is fixed.After removing casing bottom temporary supporting spandrel girder, just realized the conversion of power system to this device.After jackscrew 4, top rail 1, upper fulcrum nut 3 are installed successively, just completed whole lift-up device equipment.Jackscrew 4 jackings hold out against top rail 1, unclamp the rear decline jackscrew 4 of lower fulcrum nut 6 again stressed to lower fulcrum nut 6, after again the jackscrew 4 supreme fulcrum nuts 3 of jacking top rail 1 are stressed after unclamping fulcrum nut 3 and moving up, enter again next circulation, with this, complete progressively stable the transferring of steel box.
It should be noted that finally: above-described embodiment is only for example of the present invention clearly is described; and not to the restriction of embodiment; for those of ordinary skill in the field; can also make other changes in different forms on the basis of the above description; here need not also can't give all embodiments exhaustive, and the apparent variation of being amplified out thus or the change still be among protection scope of the present invention.
