The utility model content
The purpose of this utility model be to provide a kind of can be with the continuous rigid frame bridge construction Hanging Basket of the front-end and back-end of moved further Hanging Basket main body, handling safety move basket device synchronously.
For achieving the above object, the technical scheme that the utility model adopted is: a kind of continuous rigid frame bridge construction Hanging Basket move basket device synchronously, comprise main couple, the crossbeam of main couple front end, be fixed on the vertical shift track of bridge floor, outer sliding beam, Hanging Basket main body and be anchored at the sliding roof beam structure of concrete outer sliding beam, main couple is fixed on the vertical shift track, the front end of outer sliding beam and the suspension rod of crossbeam are hinged, the other end is undertaken on the roller of the sliding roof beam structure of outer sliding beam, the front end of Hanging Basket main body and the lower end of suspension rod are hinged, the rear end of Hanging Basket main body is suspended on the outer sliding beam by rear suspension bar, slide the rear end of beam outside, on outer sliding beam and suspension rod hinged place and the crossbeam angle pulley is installed all, be provided with pre-buried ring in casting beams section, wire rope is fixed on centre position, outer sliding beam suspension bottom, walk around the angle pulley of outer sliding beam rear part then backward, walk around the angle pulley of outer sliding beam front end more forward, continue upwards to walk around the angle pulley on the crossbeam, finally be fixed on the concrete embedded ring of case beam of having built the last period.
The angle pulley of described outer sliding beam rear end has two, and they are on same vertical curve.
Be equipped with length-adjustment holes on described suspension rod and the rear suspension bar, can regulate the length of suspension rod, rear suspension bar, to adapt to building without thickness case beam.
The bottom of described main couple is provided with the mobile wheel that matches with the vertical shift track.
Described main couple bottom is provided with and can promotes the hydraulic jack that main couple vertically moves.
After the utility model adopts said structure, by the rear end of sliding beam outside, on sliding beam and suspension rod hinged place and the crossbeam angle pulley is set outward, be provided with pre-buried ring in casting beams section, wire rope is fixed on centre position, outer sliding beam suspension bottom, walk around the angle pulley of outer sliding beam rear part then backward, walk around the angle pulley of outer sliding beam front end more forward, the angle pulley before continuing upwards to walk around on the top rail finally is fixed on the concrete embedded ring of case beam of having built the last period; Therefore, during the reach main couple, wire rope around the crossbeam angle pulley also moves forward, then wire rope produces an outer sliding beam suspension wheel suspension rod of back pull pulling simultaneously and makes it to keep plumbness, prevent that it from moving forward with Hanging Basket external side of main body mould and lose outer sliding beam suspension wheel suspension rod, provide forward power by the externally sliding beam of this wire rope simultaneously, reach and make outer sliding beam and main couple advanced in unison, the front-end and back-end that make the Hanging Basket main body have avoided suspension rod to lose with the moved further purpose; Avoid the artificial beam of below bridge floor, sliding outside the promotion to advance, improved the safety that moves basket greatly.
