Description
Technical field
Bridge construction equipment Bridge Erector technical field is the utility model is related to, more particularly to a kind of symmetrical formula bridge formation of setting a roof beam in place
Machine.
Background technology
Bridge Erector, it is the equipment for prefabricated beam piece to be placed into prefabricated bridge pier up.Bridge Erector has belonged to
Heavy-duty machine category, because its major function is to lift beam piece, put down after being then transported to position.But Bridge Erector with general sense
Crane be very different.The condition of Bridge Erector requirement is harsh, and traveling on beam piece be present, or cries vertical shift.Build bridge
It is several that machine is divided into erection highway bridge, conventional railway bridge, railway of passengers' private line bridge etc..
Bridge Erector generally comprises：Horn, trolley, No.1 post, No. two posts and No. three posts.
Horn is the support main beam of Bridge Erector, is double box-beam structures, according to the force status of horn and finite element analysis meter
Calculate, every box beam casting is into box variable cross-section form.
Bridge Erector is furnished with two trolleys, there is each independent lifting mechanism, running mechanism and transverse-moving mechanism.Every is risen
Weight dolly is equipped with two sets of independent lifting mechanisms, and two sets of lifting mechanisms of rear dolly make left and right suspension centre stress equal by force equalization mechanism
Weighing apparatus, so as to which four-point lifting during Bridge Erector hanging beam operation is converted into three suspension centres, make box beam equilibrium stand under load, quiet takeoff and landing.
No.1 post is the front leg strut of Bridge Erector, is supported on the pier first half support pinner of front.Mainly by support change gear machine
Structure, folding column, telescopic mast etc. form.Set a roof beam in place operation when with horn it is longitudinally fixed into articulated structure, turn into flexible leg, with machine
Arm, No. two post composition gantry frame structures, meet operation support requirement of setting a roof beam in place.Can be relative between No.1 post and horn during vertical shift operation
Motion, realizes Bridge Erector stride vertical shift.No.1 post is provided with fold mechanism, can meet normally to set a roof beam in place and last hole box beam erection
When No.1 post on abutment support needs.No.1 post and horn have three fixed positions to meet three kinds of different spans box beams
Set up.
No. two posts are located in the middle part of horn, are consolidated with horn, are rigid legs.The sill of No. two posts is provided with two supporting legs,
Pad and the dismounting of support sleeper are realized by hydraulic jack, meets to change stable support when walking and set a roof beam in place operation during vertical shift and requires.
Two supporting legs have transverse-moving mechanism, horn yaw are driven by traversing No. two posts of oil cylinder pushing, so as to laterally adjust bridge formation seat in the plane
Put, accommodation curve is set a roof beam in place needs.Because beam car packs the needs of Bridge Erector operating mode, sill is designed to detachable.
No. three posts be Bridge Erector vertical shift driving pillar, for meet beam car feeding beam by and Bridge Erector vertical shift driving require,
It is designed to portal-framed structure.It is made up of lifting column, fold mechanism, running mechanism, hydraulic suspension balancer, steering mechanism etc..
Bridge Erector has set up highway and railroad bridge very generally, the Bridge Erector used both at home and abroad at present, is setting up letter
During strutbeam, hanging beam dolly is first laterally moved to two girder truss centre positions, and front and rear hanging beam dolly coordinates hanging beam, vertical shift to two abutments it
Between, then traversing Bridge Erector and hanging beam dolly fall beam to accurate location.
With rapid development of economy, there occurs great variety, highway, railway traffic system to have considerable for the vehicles
Sustainable development.During road traffic is built, bridge, the progress of bridge construction construction of grand bridge are completed to whole piece traffic route
Work has significant impact.To improve bridge construction efficiency, generally using Prefabricated Concrete beam, transported, set up using setting up girder, compared with
Cast-in-situ Beam greatly improved construction quality and speed in the past, had saved cost.At present in bridge construction, especially highway bridge
Construction, a bridge block are made up of porous (across) bridge, are made up of per bridge multi-disc Prefabricated Concrete beam.The process for setting up such concrete beam before this
For：Beam car packs monolithic concrete beam to end of the bridge from precast beam field, then coordinates Bridge Erector trolley from bridge formation drive end unit feeding beam
(i.e. feeding beam on bridge floor), feeding beam in place after trolley is traversing falls beam afterwards in place, a process of setting a roof beam in place sets up a piece of concrete beam.Set up
During the side girders of circuit one (per the outermost concrete beam of bridge), to ensure safety, Bridge Erector other side need to carry out drawing anchor or adding matching somebody with somebody
Weight, to increase complete machine lateral stability, therefore, cause to construct comparatively laborious, efficiency is low.
