Abstract
The invention discloses a rear propulsion cradle. The rear propulsion cradle comprises a main girder, lifting cases, lifting bars, cross beams, a pulley and a pair of horn beams, wherein the main girder is transversely arranged on a bridge web, the lifting cases are vertically and symmetrically arranged at two ends of the main girder, the lifting bars are arranged on the main girder symmetrically, the cross beam is connected at the bottoms of the lifting cases and the lifting bars, the pulley is hung at the bottom of the cross beam, the pair of horn beams are symmetrically arranged at two sides of the middle of the main girder along the longitudinal direction, a main frame is connected at the bottom of the pulley, therefore, when the main frame moves longitudinally, the pulley firstly drives the main frame to open towards two sides, then the main frame moves longitudinally, and the rear propulsion cradle plays a role of a stable supporting point, thus the construction cost is low and the operation is simple.
Description
Technical field
the present invention relates to backward propulsion hanging bracket.
Background technology
in bridge construction, after a bridge beam is poured, need to be by main frame vertical shift to next bridge Liang Chu, to carry out the cast of next bridge beam, prior art is a kind of for the bracket of the stable support function to main frame is set at least three continuous bridge piers, main frame is opened to both sides and vertical shift is arrived after next bridge beam, first bracket has lost the effect of supporting, now first bracket is removed, prior art is another kind of comprises a bottom supporting mechanism on the ground for setting gradually three contour strong points, bracket on continuous two bridge piers, main frame is opened and vertical shift is arrived after next bridge beam, take supporting mechanism away, construction cost is higher like this, operation is comparatively complicated.
Summary of the invention
the object of this invention is to provide construction cost a kind of backward propulsion hanging bracket low, simple to operate.
for achieving the above object, the invention provides a kind of backward propulsion hanging bracket, comprise the passive girder that is horizontally installed on bridge web top, be arranged on a pair of box at described girder both ends, be connected to the pair of beams of described a pair of box bottom, being suspended on respectively described pair of beams bottom can be along the coaster of described pair of beams transverse shifting, described pair of beams is parallel to described girder setting, described pair of beams coaxially arranges, the outer end of described pair of beams exceeds described girder both ends in the horizontal direction, the inner end of described pair of beams is pressed close to described bridge web, described a pair of box is vertically arranged on described bridge web outside, the top of described a pair of box is connected to the bottom at described girder two ends, the bottom of described a pair of box connects described pair of beams, symmetrical on described girder a pair of suspension rod must be set, described suspension rod is vertically through described girder and described bridge web, described suspension rod top connects described girder, bottom is connected on described crossbeam near described inner end place.
preferably, at described bridge web top, a pair of support top is set, described a pair of support top is symmetricly set on both sides, described girder middle part in a longitudinal direction, be provided for stablizing the ox horn beam of described girder at the top of described support top, described ox horn back portion is pushed against described girder side, and bottom is fixed on described support top.
because technique scheme is used, the present invention compared with prior art has following advantages and effect: the passive girder of horizontally set above bridge web, at girder two ends, box and suspension rod are set respectively, box and suspension rod bottom connecting cross beam, on crossbeam, hang the coaster that can move along crossbeam is set, under coaster, connect the main frame that bridge construction uses, like this in the time of main frame vertical shift, first coaster drives main frame to open to both sides, then main frame vertical shift, now, backward propulsion hanging bracket plays the effect of a strong point, use like this backward propulsion hanging bracket of the present invention can complete the vertical shift of main frame, construction cost is lower, simple to operate.
accompanying drawing explanation:
accompanying drawing 1 is looked schematic diagram for master of the present invention;
accompanying drawing 2 is schematic side view of the present invention;
the specific embodiment:
shown in Figure 1, the girder 1 of steel box girder is laterally fixedly installed on bridge web 6, be symmetrical arranged the vertical box 3 being welded as a whole with girder 1 at girder 1 both ends, box 3 is positioned at the outside of bridge web 6, the another vertical suspension rod 2 that is symmetrical arranged on girder 1, suspension rod 2 is positioned at the inner side of box 3, suspension rod 2 is through bridge web 6, be bolted mode in box 3 and suspension rod 2 bottoms and be connected with the symmetrical crossbeam 4 that lays respectively at bridge web 6 both sides external, crossbeam 4 is parallel to girder 1, the outer end of crossbeam 4 exceeds the both ends of girder 1 in the horizontal direction, use for workman and walk, the inner end of crossbeam 4 is pressed close to bridge web 6 and is arranged, setting is suspended on the coaster 5 can moving along crossbeam 4 in the bottom of crossbeam 4, coaster hangs the main frame of bridge construction for 5 times, main frame can be followed the motion of coaster 5 and separated or close up.
shown in Figure 2, at the top of bridge web 6, a pair of support top 8 is set along the longitudinal direction, a pair of support top 8 is symmetricly set on the both sides, middle part of girder 1, at a pair of support top 8 tops, the ox horn beam 7 that stable girder 1 acts on is set, the bottom of ox horn beam 7 is fixed on support top 8, the welded top of ox horn beam 7 is on girder 1 middle part and push against girder 1, ox horn beam 7 can guarantee backward propulsion hanging bracket of the present invention stability in a longitudinal direction, in the time of main frame vertical shift, backward propulsion hanging bracket of the present invention can play the effect of a stable strong point.
