Specific embodiment

Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on Embodiment in the present invention, those of ordinary skill in the art are obtained every other under that premise of not paying creative labor Embodiment shall fall within the protection scope of the present invention.

As shown in Fig. 1 to 5, a kind of precast segmental beam regulating system, including support platform 1, support platform 1, which is equipped with, to be located at The expansion pedestal of rectangle quadrangle, expansion pedestal preferably use hydraulic jack, and expansion pedestal is flexible up and down, and it is perpendicular can to adjust fulcrum To position.

Expansion pedestal includes active expansion pedestal 2 and driven expansion pedestal 3, and active expansion pedestal 2 is located at rectangle pair of horns It goes up and slides and be located in support platform 1, active expansion pedestal 2 and driving mechanism 6 are hinged, can be controlled actively by driving mechanism Expansion pedestal position in the horizontal direction, each active expansion pedestal 2 and two driving mechanisms 6 are hinged, and two driving mechanism 6 In the adjacent two sides edge direction of rectangle, i.e. two lateral arrangements one of driving mechanism one are vertically arranged, and complete an active jointly The adjustment of the transverse and longitudinal position of expansion pedestal, driving mechanism preferably use hydraulic cylinder, driving mechanism 6 and are fixed on support carriers 1 On driving support 7 it is hinged, driving support 7 provides reaction force for driving mechanism.

Driven expansion pedestal 3 is located at another diagonal upper and fixation of rectangle and is located in support platform 1, and driven expansion pedestal cannot It moves horizontally, only according to the adjustment of active expansion pedestal, cooperates precast segmental beam different directions and inclination angle, the top of expansion pedestal Portion is equipped with hemisphere 4, and hemisphere 4 is located in half ball groove of 5 bottom of cover board, and spherical shape cooperation meets the various freedom degrees of beam sections Adjustment, cover board 5 directly fit the bottom for being supported on beam sections.

Additional, support platform 1 is equipped with cylinder 10, and the sand of support tube plug 9 is equipped in cylinder 10, and tube plug is inserted in cylinder Interior, the top of tube plug 9 is equipped with half ball groove, and rotating freely for cover, cylinder are realized in the hemisphere cooperation of half ball groove and 8 bottom of cover Lid directly supports box beam to be rectangular, and cover is different according to the inclination angle of box beam, carries out spin stabilization fitting and is supported in box beam.

Tube plug 9 includes rectangular seben 91, and the bottom of seben 91 and match pipe 92 weld, match in pipe 92 and poured concrete 93, half ball groove of top formation of seben 91 and concrete 93.The hemisphere of 8 bottom of cover and half ball groove activity cooperation, cylinder 10 It including bobbin 101, matches pipe 92 and is inserted in bobbin 101, the bottom of bobbin 101 and bottom plate 102 weld, and support is equipped in bobbin 101 The sand of tube plug, the side of bobbin 101 are equipped with nut 103, and nut 103 is threadedly coupled with screw 104 is adjusted, and adjust screw 104 It extends in bobbin 6.

Nut 103 is equipped with positioning screw 105 by screw hole, and positioning screw 105 passes through screw hole and contacts with screw 103 is adjusted, After the completion of the adjustment of the height of support, positioning screw is tightened and is held out against in adjusting screw, avoids adjusting screw hair in support Raw movement, guarantee support stablizes support.Sand carries out flexible support to tube plug, changes adjusting screw and protrudes into the length in bobbin Degree, so that the height of entire support is adjustable, further increases the applicability of support to change the height of sand.

Bottom plate 102 is equipped with the floor 106 being provided with cross-shaped outside bobbin 101, and floor 106 can be improved cylinder The support strength of pipe.Floor 106 is equipped with the hole for wearing rope, finishes in support use, needs transition in use, using rope Cover, tube plug and cylinder can be banded together, convenient for the mobile transport of a whole set of support.

Bottom plate 102 is equipped in cross cloth setting in the floor 106 inside bobbin 101, and floor 106 can be improved bobbin Support strength.Floor 106 will be divided into four sand warehouses in bobbin 101, floor 106 is equipped with the hole of connection sand warehouse, be convenient for sand The flowing of sand between storehouse.

When section beam is adjusted, cover can follow box beam change in location to rotate or tilt, and not influence the quick of box beam It adjusts, after the adjusting for completing beam sections, sand cylinder can carry out Auxiliary support to the edge of beam body, only need to adjust screw, just can Support quickly is replaced to box beam, withdraws from regulating system, realizes quick transition.

It is 4 corner location coordinate of beam bottom plate and elevation, this adjusting system that this regulating system, which provides 6 coordinate transformations according to design, 4 fulcrums are altogether counted, 4 fulcrums are located at 4 angle points of beam section bottom plate rectangle position, wherein 2 are actively adjusting, are located at rectangle Pair of horns on, in addition 2 are driven adjusting, positioned at rectangle it is another it is diagonal on, be supported, used using telescopic jack Hydraulic system is accurately adjusted, and fulcrum and beam-ends contact point are metal ball body, adds steel lid on sphere, steel lid is connect with beam bottom Touching, the position that hydraulic system changes support rotates sphere, to accurately be adjusted to 4 fulcrum coordinates.

The course of work: expansion pedestal is installed to support platform corresponding position before lifting, checks oil pump route, no problem Handling is carried out to total system afterwards, temporary rest pier pier top of setting a roof beam in place is hoisted to, then whole system is fixed using bolt, is prevented Stop bit moves.Coordinate position and elevation at the top of measurement observation jack, empirically the pre- lift 3mm elevation of value, coordinate position press absolute value 2mm control is completed to carry out calibration adjustment after adjusting on handling precast beam to regulating system to beam body position after stable placement, make Overturning adjustment slope and coordinate position in length and breadth are integrally carried out to beam with active jack ball joint-rotating, three-dimensional driving is common to be adjusted, The position that fulcrum can be rapidly completed is adjusted, and is shortened regulating time, is reduced the investment of man power and material.

The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
