As shown in Figure 1, Figure 2 and Figure 3, a kind of hanging basket main truss front fulcrum height tunable arrangement, including sliding ship connecting seat 3,
Bearing base 4 adjusts lead screw 5, front fulcrum jack 9.Sliding ship connecting seat 3 is connect with bearing base 4 by adjusting lead screw 5, bearing base 4
Height on adjusting lead screw 5 is adjustable；Front fulcrum jack 9 is passed through from 3 central hollow region of sliding ship connecting seat, withstands on bearing base
Below 4, related to bearing base 4 sliding ship connecting seat 3 plays the role of jack-up when front fulcrum jack stretches out.
The hanging basket main truss height tunable arrangement further includes track 1, sliding ship 2, adjusting nut 6, bracing members 10.Sliding ship
Connecting seat 3 is connect by sliding ship axis pin with sliding ship 2, and sliding ship 2 is fallen on track 1, and sliding ship connecting seat 3 is along with sliding ship 2 in track 1
On move together.In the top and bottom of bearing base 4, each adjusting nut 6 that is arranged is set on adjusting lead screw 5, to bearing base 4
Play clamping and supporting role；Further, can two or more adjusting nuts 6 be set in 4 bottom of bearing base, in preceding branch
Point jack plays bearing base 4 strong supporting role when falling after rise.Bracing members 10 are placed among track 1, for supporting preceding branch
Point jack 9.
In order to keep the balance of object, track 1 to be arranged in parallel with two, sliding ship 2 is respectively seated at there are two also corresponding to
On this two tracks；Sliding ship connecting seat 3 is connected on two sliding ships 2.In one embodiment, sliding ship connecting seat 3 can also be set
Two are set to, is connected on two sliding ships 2, two sliding ship connecting seats 3 connect bearing base 4 jointly.In another embodiment,
Sliding ship connecting seat 3 could be provided as an entirety and be located on two sliding ships 2, as shown in Figure 3, Figure 4, can more can guarantee in this way
The stationarity of sliding ship connecting seat 3 and the levelness of bearing base 4；Further, in this embodiment, sliding ship connecting seat 3 can be by
The lateral steel plates of two I22b I-steel 31 and four blocks 32 connect integral, and middle section is vacated, for placing front fulcrum jack
9, still further, in this embodiment, sliding ship connecting seat 3 can be connect by four adjusting lead screws 5 with bearing base 4 in quadrangle.
Front fulcrum jack 9 is placed at the intermediate gaps of track 1, sliding ship 2 and sliding ship connecting seat 3, front fulcrum jack 9 by
Bracing members 10 support；Further, on this basis, front fulcrum jack 9 can also hang over bearing base by spring 7 and anchor ear 8
Lower section, spring 7 are fixed on 4 lower section of bearing base, and the other end connects anchor ear 8, and anchor ear 8 is sleeved on front fulcrum jack 9, before Hanging Basket
When shifting, front fulcrum jack is bounced back, jack is made to come to nothing, spring 7 slings front fulcrum jack, with the Forward of Hanging Basket
Forward, removes from by the process of artificial jack for moving, time saving and energy saving.
Further, the track is I36b I-steel, enhances stability, two I36b I-steel center spacing (i.e. two
Track) 62cm, 1 Two bors d's oeuveres I16 channel steels are set every 1m and are laterally linked；Accordingly, two I22b of the sliding ship connecting seat 3
I-steel center spacing is also 62cm.
Further, the thickness of four blocks of the sliding ship connecting seat 3 lateral steel plates is respectively 2cm.
Further, the specification that the sliding ship axis pin uses is diameter 80mm, long 165mm, material 40Cr.
Further, for the specification that the adjusting lead screw 5 uses for diameter 70mm, long 850mm, material is 45# steel.
Further, the front fulcrum jack 9 is 200t self-locking jacks.
When curvilinear motion section box girder construction, since setting superelevation needs, the horizontal slope of box beam can become with the variation of curvature
Change, the horizontal slope of the adjacent block of Hanging Basket cantilever also differs, and by front fulcrum jack 9 and adjusts the cooperation of lead screw 5, adjusts Hanging Basket master
The absolute altitude of truss front fulcrum makes several main couples of Hanging Basket be in same absolute altitude, and detailed process is as follows：
The previous block concreting of step 1) finishes and after stretch-draw prestressing force mud jacking, track advancing, before preparing Hanging Basket
It moves；
Step 2) loosens front fulcrum jack 9, so that sliding ship 2 is fallen on track 1, before jack pushing tow Hanging Basket of walking
Move on to next block, hanging basket advancing in place after, bracing members 10 are placed on 9 lower section of front fulcrum jack；
Step 3) calculates main couple set height adjustment according to the height difference of track.The adjusting nut 6 of 4 top of bearing base is put
Pine, quantity of margin are set height adjustment, and front fulcrum jack 9 slowly ejects, and bearing base 4 is jacked up, and measure main couple absolute altitude, it is ensured that
Height difference between main couple adjusts the adjusting nut 6 of 4 upper and lower of bearing base, is allowed to hold out against with bearing base 4 within 5mm.
Step 4) continues to jack up on front fulcrum jack 9, and sliding ship 2 and track 1 is made to come to nothing about 1cm, will after leveling front fulcrum
Front fulcrum jack 9 is locked, binds cantilever section reinforcing bar, casting concrete.
Step 5) repeats the above steps, and completes the construction of box beam whole block.
In the whole process, when Hanging Basket is walked, front fulcrum jack 9 is fallen, by adjusting lead screw 5 and adjusting nut 6 by
Power, hanging basket advancing when concreting, front fulcrum jack 9 are jacked up, by jack stress, it is ensured that concreting process
Middle bearing capacity is met the requirements.
Exemplified as above is only the explanation to the utility model, does not constitute protection domain limitation, every and the utility model
It is identical or as design and belong within the scope of utility model protection.The component and structure category one's own profession that embodiment does not describe in detail
Common or means known in industry, differ narration here.
