Abstract
The utility model discloses a backward propulsion hanging bracket, which comprises a girder laterally arranged on a bridge webplate, a hanging box vertically and symmetrically arranged at the two end parts of the girder, a suspension rod symmetrically arranged on the girder, a beam for connecting the suspension box and the bottom of the suspension rod, a pulley suspended at the bottom of the beam, and a pair of longhorn beams longitudinally and symmetrically arranged at the two sides of the middle part of the girder, wherein the bottom of the pulley is connected with a maim frame, so when the main frame moves, the pulley drives the main frame to open towards the two side at first, then the main frame longitudinally moves, the backward propulsion hanging bracket plays the role of a stable supporting point, consequently, the backward propulsion hanging bracket has low construction cost and is simple to operate.
Description
Technical field
The utility model relates to the back and advances suspension bracket
Background technology
In the bridge construction, stride after bridge cast finishes when one, the main frame vertical shift need be striden the bridge place to next, so that carry out the cast that next strides bridge, prior art is a kind of for the carriage to the stable support effect of main frame is set at least three continuous bridge piers, main frame is opened and after vertical shift strides bridge to next to both sides, first carriage has promptly lost the effect of supporting, remove first carriage this moment, prior art is another kind of to comprise a bottom supporting mechanism on the ground for setting gradually three contour strong points, carriage on continuous two bridge piers, after main frame is opened and vertical shift strides bridge to next, take supporting mechanism away, construction cost is higher like this, and operation is comparatively complicated
Summary of the invention
The purpose of this utility model provides construction cost a kind of back low, simple to operate and advances suspension bracket.
For achieving the above object, the technical solution adopted in the utility model is: a kind of back advances suspension 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 described pair of beams bottom respectively can be along the laterally mobile coaster of described pair of beams, described pair of beams is parallel to described girder setting, the coaxial setting of described pair of beams, 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 vertically is arranged on described bridge web outside, the top of described a pair of box is connected the bottom at described girder two ends, the bottom of described a pair of box connects described pair of beams, bilateral symmetry must be provided with a pair of suspension rod on described girder, described suspension rod vertically passes described girder and described bridge web, described suspension rod top connects described girder, and the bottom is connected on the described crossbeam near described inner end place.
Preferably, at described bridge web top a pair of support is set, described a pair of support withstands on and is symmetricly set on both sides, described girder middle part on the longitudinal direction, be provided for stablizing the ox horn beam of described girder at the top of described support, described ox horn back portion pushes against in described girder side, and the bottom is fixed on described the support.
Because the utilization of technique scheme, the utility model compared with prior art has following advantage: the passive girder of horizontally set above the bridge web, at the girder two ends box and suspension rod are set respectively, box is connected crossbeam with the suspension rod bottom, the coaster that can move along crossbeam hang to be set on crossbeam, coaster connects the main frame that bridge construction uses down, like this when the main frame vertical shift, coaster at first drives main frame and opens to both sides, main frame vertical shift then, at this moment, the back advances suspension bracket to play the effect of a strong point, use back of the present utility model to advance suspension bracket can finish the vertical shift of main frame like this, construction cost is lower, and is simple to operate.
Description of drawings
Accompanying drawing 2 is a schematic side view of the present utility model.
The specific embodiment
Further set forth structure of the present utility model below in conjunction with accompanying drawing.
Referring to shown in Figure 1, girder 1 crosswise fixed of steel box-beam structure is arranged on the bridge web 6, be symmetrical arranged the vertical box 3 that is welded as a whole with girder 1 at girder 1 both ends, box 3 is positioned at the outside of bridge web 6, on girder 1, be symmetrical arranged vertical suspension rod 2 in addition, suspension rod 2 is positioned at the inboard of box 3, suspension rod 2 passes bridge web 6, be connected with the crossbeam 4 that lays respectively at bridge web 6 both sides external of symmetry by bolt connecting mode in box 3 and suspension rod 2 bottoms, 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 walking, the inner end of crossbeam 4 is pressed close to bridge web 6 and is provided with, and the coaster 5 that can move along crossbeam 4 in the bottom that is suspended on crossbeam 4 is set, coaster hangs the main frame of bridge construction for 5 times, and main frame can be followed the motion of coaster 5 and be separated or close up.
Referring to shown in Figure 2, at the top of bridge web 6 a pair of support 8 is set along the longitudinal direction, a pair of support 8 is symmetricly set on the both sides, middle part of girder 1, the ox horn beam 7 of stable girder 1 effect has been set at a pair of support 8 tops, the bottom of ox horn beam 7 is fixed on the support 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 that back of the present utility model advances suspension bracket stability in a longitudinal direction, when the main frame vertical shift, back of the present utility model advances suspension bracket can play the effect of a stable strong point
Claims (2)
1. advance suspension bracket after one kind, 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 described pair of beams bottom respectively can be along the laterally mobile coaster of described pair of beams, it is characterized in that: described pair of beams is parallel to described girder setting, the coaxial setting of described pair of beams, 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 vertically is arranged on described bridge web outside, the top of described a pair of box is connected the bottom at described girder two ends, the bottom of described a pair of box connects described pair of beams, bilateral symmetry must be provided with a pair of suspension rod on described girder, described suspension rod vertically passes described girder and described bridge web, described suspension rod top connects described girder, and the bottom is connected on the described crossbeam near described inner end place.
