Abstract
The utility model discloses a kind of bridge rotating a complete set of equipment, the bottom surface of girder is provided with bridge pier shaft, the bottom of bridge pier shaft by ball pivot and basis hinged, bridge pier with it symmetry is wound with two groups of drag cables, the exit of drag cable is connected with punching jack, punching jack is fixed on the counter-force seat at basic top, and the position that bridge pier is wound around drag cable is with it provided with drag cable carding apparatus.The inner stating drag cable is anchored at the inside of bridge pier shaft by ground tackle.The part that drag cable is positioned at the outer wall of bridge pier shaft inside is separated by bellows and bridge pier shaft.By the boundling to steel strand, combing, make the every root steel strand uniform force in bridge construction by swing in steel wire bundle, synchronous by punching jack process thread, thus realize the operation of turning of bridge, improve turn speed and efficiency.
Description
Technical field
The utility model relates to a kind of Bridge Rotation Construction Technique equipment, particularly relates to a kind of bridge rotating a complete set of equipment.
Background technology
At present, the rotator construction of domestic large bridge, many employing large-tonnage Rotary ball hinges, utilize in ball pivot and pier shaft binding site pre-buried steel strand bundle, and being wound around pier shaft, steel wire bundle provides power by the punching jack that symmetrical frame on counter-force seat is vertical for turning, and realizes the body twist of bridge.
Because steel wire bundle mutually covers superposition in pre-buried and winding process, cause Internal and external cycle steel strand length there are differences, in the process of turning, often occur that outer ring steel strand loosen, the situation that inner ring tension of steel strand increases.
Summary of the invention
The purpose of this utility model is to provide a kind of bridge rotating a complete set of equipment that can realize the work of Bridge Rotation Construction Technique equipment collaboration.
The purpose of this utility model is achieved through the following technical solutions:
Bridge rotating a complete set of equipment of the present utility model, the bottom surface of girder is provided with bridge pier shaft, the bottom of described bridge pier shaft by ball pivot and basis hinged, described bridge pier with it symmetry is wound with two groups of drag cables, the exit of described drag cable is connected with punching jack, described punching jack is fixed on the counter-force seat at basic top, and the position that described bridge pier is wound around drag cable is with it provided with drag cable carding apparatus.
The technical scheme provided as can be seen from above-mentioned the utility model, the bridge rotating a complete set of equipment that the utility model embodiment provides, a kind of the complete sets of equipment that large heavy girder can be provided to turn, this a complete set of equipment is by the boundling to steel wire bundle, combing, make the every root steel strand uniform force in bridge construction by swing in steel wire bundle, synchronous by punching jack process thread, thus realize the operation of turning of bridge, improve turn speed and efficiency.

Detailed description of the invention
To be described in further detail the utility model embodiment below.
Bridge rotating a complete set of equipment of the present utility model, its preferably detailed description of the invention be:
The bottom surface of girder is provided with bridge pier shaft, the bottom of described bridge pier shaft by ball pivot and basis hinged, described bridge pier with it symmetry is wound with two groups of drag cables, the exit of described drag cable is connected with punching jack, described punching jack is fixed on the counter-force seat at basic top, and the position that described bridge pier is wound around drag cable is with it provided with drag cable carding apparatus.
The inner of described drag cable is anchored at the inside of described bridge pier shaft by ground tackle.
The outer wall that described drag cable is positioned at the part of described bridge pier shaft inside is separated by bellows and described bridge pier shaft.
Described drag cable is steel wire bundle.
Bridge rotating a complete set of equipment of the present utility model, a kind of the complete sets of equipment that large heavy girder can be provided to turn, this a complete set of equipment is by the boundling to steel wire bundle, combing, make the every root steel strand uniform force in bridge construction by swing in steel wire bundle, synchronous by punching jack process thread, thus realize the operation of turning of bridge, improve turn speed and efficiency.
Specific embodiment:
As shown in Figure 1 and Figure 2, this bridge rotating a complete set of equipment comprises A group, B group two restraints the parts such as steel strand drag cable, ground tackle, bellows, drag cable carding apparatus, punching jacking equipment.
1, A group, B group steel strand drag cable:
Standard component, for being wound around pier shaft, provides rotatory force.
2, ground tackle:
Standard component, at ball pivot and pier shaft binding site anchoring steel strand.
3, bellows:
Standard component, steel strand boundling at random.
4, drag cable carding apparatus:
Workpiece, combing steel wire bundle, makes every root steel strand wound in parallel in pier shaft.
5, punching jack:
Standard component, provides required drive of turning.
Operating principle of the present utility model is:
Punching jack provides power for turning, and apply pulling force by punching jack pair steel wire bundle, steel strand pull pier shaft, and integral bridge is rotated, thus realize Bridge Rotation Construction Technique object.The pulling force that punching jack produces passes to bridge pier shaft to be turned by steel wire bundle.Pull bridge pier shaft to rotate by the steel strand being wound around pier shaft, thus drive whole bridge to complete body twist.By steel strand carding equipment, make steel wire bundle thread synchronization when stressed.
The above; be only the utility model preferably detailed description of the invention; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claims.
