Described oil path control system is that the delivery valve by the oil pressure pumping plant is connected by the entrance point of oil pipe with the energy storage valve, the output of energy storage valve has a plurality of delivery valves, a plurality of jack in parallel, the oil return valve of jack is connected on the parallel interface of another energy storage valve, and the concentrated oil return valve of energy storage valve is connected on the oil return valve of oil pressure pumping plant by oil pipe.
Described slide plate is the polytetrafluoroethylene (PTFE) slide plate.
Described vertical jack and level jack are a plurality of.
Described bearing is detachable, and it is a series of different specifications as required.
Described rotating hinge is spherical, and its radius and structure are a series of different specifications as required.
Characteristics of the present utility model are as follows: 1) rotating hinge radius and structure can be according to member designs corner angle design, and applicability is strong; 2) carry out the positioning of level and vertical direction by level jack and vertical jack pair member, thereby reach high accuracy positioning and aligning precision height, can reach in the 1mm large-scale component; 3) the energy storage valve can mean allocation oil pressure to each jack stable when guaranteeing jack unloading, thereby the control jack initiatively and passive and synchronous property, avoids occurring the jacking asynchrony phenomenon to the member infringement and may cause security incident under big load action; 4) need not increase special equipment, be combined and bearing can be dismantled by conventional equipment, the versatility of favourable and site operation can also be had enough to meet the need use, reduces construction cost; 5) improve the adjustment tonnage and the adjustment distance of large-scale component, and helped bringing into play the lifting ability of large-scale hanging device; 6) large-scale component can become whole in factory process, and once lifting is avoided or reduced fritter section on-site consolidation quantities; Reduce the on-site consolidation seam, effectively guaranteed construction quality; 7) make big member once in place, avoid big member, reduced the temporary support structure workload, effectively reduce production cost by the many problems of the on-the-spot required interim strong point of spelling of primary structural component; 8) little from heavy and light, size, execute-in-place is convenient and practical.
Description of drawings:
The utility model is described in further detail below in conjunction with the embodiment accompanying drawing:
Fig. 1 is a large-scale component rackwork facade layout drawing;
Fig. 2 is a large-scale component rackwork floor plan;
Fig. 3 is a jack synchronism control oil circuit layout drawing.
Among the figure: 1, base; 2, removable bearing; 3, vertical jack; 4, level jack; 5, billet; 6, rotating hinge; 7, polytetrafluoroethylene (PTFE) slide plate; 8, energy storage valve; 9, oil pressure pumping plant; 10, oil pipe.
The specific embodiment:
As Fig. 1, as shown in Figure 2, the accurate rackwork of large-scale component, it is made of bearing, jack, billet, rotating hinge, slide plate at least, its jack comprises vertical jack 3 and level jack 4, jack is connected with oil path control system; Bearing comprises base 1 and removable bearing 2, and removable bearing 2 is sand bucket shape structures; Base 1 is fixed on the spandrel girder, and at base 1 top polytetrafluoroethylene (PTFE) slide plate 7, draw-in groove is left in removable bearing 2 bottoms; Level jack 4 is horizontally set on removable bearing 2 and needs the positioning side, and it can be a plurality of; Billet 5 is placed on removable bearing 2 tops, and rotating hinge 6 is set between billet 5 and the member.
Embodiment 1: select the position of interim fulcrum according to element structure, select suitable detachable bearing, jack and the rotating hinge 6 of specification according to the distribution load of construction weight and each interim fulcrum.
The base 1 of bearing is fixed on the spandrel girder, at base 1 top tiling polytetrafluoroethylene (PTFE) slide plate 7, the stuck polytetrafluoroethylene (PTFE) slide plate 7 of draw-in groove of removable bearing 2 bottoms, two level jack 4 are horizontally set on removable bearing 2 needs the positioning side, drive member by the removable bearing 2 of level jack 4 synchronous push and carry out the plan-position adjustment, billet 5 is placed on removable bearing 2 tops, spherical rotating hinge 6 is set, by delivering that rotating hinge 6 adaptation members may exist between billet 5 and the member; Each vertically places 1 vertical jack 3 bearing left and right sides symmetry, place billet 5 according to member elevation needs in vertical jack 3 bottoms, at first use vertical jack 3 jack-up members when adjusting height, bearing and member are broken away from, place 1 billet 5 on the bearing to reach the high range request of member adding.Rear support still is in high-stress state because member is adjusted to the right place, brings difficulty for the dismounting of bearing, and therefore removable bearing 2 is sand bucket shape structures, and frame conveniently falls.
As shown in Figure 3, oil path control system is to be connected with the entrance point of energy storage valve 8 by oil pipe 10 by the delivery valve of oil pressure pumping plant 9, the output of energy storage valve 8 has a plurality of delivery valves, can two vertical jack 3 in parallel, the oil return valve of vertical jack 3 is connected on the parallel interface of another energy storage valve 8, the concentrated oil return valve of energy storage valve 8 is connected on the oil return valve of oil pressure pumping plant 9 by oil pipe 10, realizes the control of passive and synchronous property.Energy storage valve 8 can the mean allocation oil pressure to each jack, cushion the unexpected variation of oil pressure simultaneously, thereby the control jack is initiatively and passive and synchronous property, avoid under big load action, occurring jacking asynchrony phenomenon and oil return and impact member is damaged.
Embodiment 2:
Substantially the same manner as Example 1, different is that it adopts at three vertical jack of each vertical placement of bearing left and right sides symmetry, four level jack 4 are horizontally set on removable bearing 2 needs the positioning side, oil path control system is connected with the entrance point of energy storage valve 8 by oil pipe 10 by the delivery valve of oil pressure pumping plant 9, the output of energy storage valve 8 has a plurality of delivery valves, can jack in parallel, the oil return valve of jack is connected on the parallel interface of another energy storage valve 8, the concentrated oil return valve of energy storage valve 8 is connected on the oil return valve of oil pressure pumping plant 9 by oil pipe 10, realizes the jacking active synchronization of jack and the passive and synchronous property that falls; Thereby solved the accurate positioning problem of super-big and overweight member.
When the weight of large-scale overweight member is too big, can arrange a plurality of jack weight of bearing carriers simultaneously, solve the accurate positioning of large-scale overweight member.This device has completed successfully the long 1020 tons big sections steel case beams positioning of Transbay Bridge, Qingdao 72m task.
