Description
Technical field
The utility model relates to the high-speed railway bridge formation machine of the whole hole of a kind of two-wire prestressed concrete box girder.
Background technology
At present, a straddle type double guide beam bridge erecting machine that uses in the railway bridge erecting machine operation, but mainly by the lifting overhead traveling crane of the girder of trussed construction and configuration vertical shift above it and be fixed on supporting leg in the front leg strut that moves forward and backward under the nose girder, the O type and the rear support leg that can upwards turn down etc. is partly formed, and girder length can not be striden 2.5 times of pier less than two.One straddle type bridge formation machine operation program is: the bridge formation machine is finished the reliable anchoring on bridge pier of contraposition, front leg strut, Beam transportation vehicle fortune beam is to the machine tail end of building bridge, the front end of beam is sling in preceding hanging beam driving, propelling chassis acting in conjunction on preceding hanging beam driving and the Beam transportation vehicle makes beam move forward to the beam you to middle supporting leg rear, sling in the rear end of beam in back hanging beam driving, the front and back common hanging beam of two drivings advances and puts in place, and the beam that falls then puts in place.This bridge formation machine via hole operation is comparatively complicated, and during via hole, rear support leg Zhi Lihou must can shrink front leg strut with the grappling of bridge formation machine tail end, can remove the anchoring of tail end in moving to behind the front leg strut behind supporting leg the place ahead, and the bridge formation machine can via hole.And when setting up first bridge, bridge formation machine tail end grappling difficulty, a straddle type bridge formation machine has determined it to produce huge working load at span centre by its via hole mode, because big cantilever via hole, its longitudinal stability is relatively poor.
The utility model content
The purpose of this utility model provides a kind of high-speed railway double guide beam bridge erecting machine, this bridge formation machine can not need be taked particular facility can finish first to stride with last and stride setting up of bridge, and efficiently solve that bridge line head strides, the beam body is striden at the end, guarantee different spans beam body, set up, via hole process complete machine safe, stable.
For achieving the above object, technical solution of the present utility model is finished like this: a kind of high-speed railway double guide beam bridge erecting machine, comprise that girder and front end thereof connect one and have the semi girder of nose girder overhead traveling crane down on it, the rigidity rear support leg of band walking carriage is equipped with at the rear portion under girder, and the anterior front end of girder is equipped with folding flexible front leg strut and has auxilliary supporting leg, its girder is provided with the hanging beam driving, and afterbody is equipped with hoist engine on it, leads around two hanging beam drivings by pull rope; Comprise that also the auxiliary lower nose girder that has supporting leg divides the mobile of body structure, correspondence is placed in the lower end of semi girder in order to support auxilliary supporting leg.
The technical solution of the utility model also comprises:
Above-mentioned girder is the box-structure body, and its front end is provided with and becomes the cross-over connection head, top is equipped with respectively the back, in, preceding horizontal-associate laterally links into an integrated entity.
Above-mentioned rigidity rear support leg is that " " support body of type is provided with running truck and hydraulic jack in its bottom to O by being.
Above-mentioned flexible front leg strut is the fixed knot by a symmetry, and its upper end is provided with roller and jack, and the lower end connects folded segment, and connecting one by the hinged fixed bearing that is provided with on the folded segment can regulate, and jack is set forms with can regulating at its fixed knot.Utilizing this roller to install with girder cooperates.
Above-mentioned auxilliary supporting leg lower end is provided with support, and the oil cylinder that go up to be provided with, and is respectively equipped with auxilliary supporting leg chassis and the anti-wheel of scratching on support, with under the nose girder listrium cooperate installation.
The good effect that the utlity model has is: this bridge formation machine adopts flexible front leg strut and rigidity O type rear support leg two fulcrums to support girder, and forming the form of setting a roof beam in place is to stride simply-supported state, makes it stressed clear and definite; And the driving of two hanging beams on this girder cooperatively interacts, and takes the beam three-dimensional motion, satisfies synchronous, the laterally fine motion adjustment of beam body allocation and transportation, and lifting beam body adopts 4 liftings, 3 balances, and beam body stress is good; Because preceding hanging beam driving, following nose girder overhead traveling crane and auxilliary supporting leg cooperate, making bridge formation machine via hole state is to stride simply-supported state, and the complete machine longitudinal stability is bigger, and is safe; In addition, the hoist engine that is adopted is rear-mounted, and driving separates with hanging beam, effectively reduces the complete machine height, and is strong by high-altitude gauge ability; In addition, this bridge formation machine has adopted height to deposit nose girder, and bridge line first is striden, last two, one mutual conductance beam body sets up a difficult problem thereby solved more conveniently, has to set a roof beam in place, transport the separation of beam operation, job execution efficient height; And can be by adopting WLAN and ether industry network control system, to guarantee the synchronism in the beam body lifting operation process; This girder length foreshortens to 1.5 times of spans by original two 2.5 times of spans of striding pier, can satisfy to use and set up setting up of 20M, 24M, the whole hole prestressed concrete box girder railroad bridge of 32M two-wire.
