Description
Technical field
The present invention relates to a kind of structure and type of attachment that is applicable to rear support leg (No. 4 supporting legs) device of bridging machine for both highway and railway.
Background technology
Because efficiency of construction and the security reliability of Bridge Erector are high, so obtain applying very widely in global highway and railway bridge construction.Highway in China and railway construction are in peak period, the beam type of speedway is very similar with the beam type of special line for passenger trains (Speed 200 km/h is following), railway transportation industrial siding and common railway line simultaneously, in order to utilize to greatest extent equipment, reduce production costs, require by the Bridge Erector that can meet the T-shaped Beams Erection Construction of speedway with regard to requiring a kind of erection construction that namely can meet the railway T-shaped beam.For the Bridge Erector of railroad bridge construction, should meet the requirement of ew line construction, can meet again the construction requirement on both wired,
On Existing Railway Line, construct, at first all constructions and haulage device must meet the railway clearance requirement, and this just requires Bridge Erector just on existing line, to set a roof beam in place and to transport must to be controlled at appearance and size in certain value range.Meeting under the prerequisite of construction requirement, reduce to greatest extent the height of erecting beam construction, increase Bridge Erector and use safe altitude.So just require the many mechanism structure on Bridge Erector compact, small and exquisite.
Summary of the invention
Purpose of the present invention provides a kind of rear landing leg device that is applicable to bridging machine for both highway and railway with the Bridge Erector that can realize speedway and railway T-shaped beam in order to solve existing weak point in above-mentioned prior art just.
Purpose of the present invention can realize by subordinate's technical measures:
The rear landing leg device that is applicable to bridging machine for both highway and railway of the present invention comprises and by guide and limit mechanism, is arranged on the following rear support leg top rail of contact beam after the girder horn in the mode be slidably matched, and the mode be bolted is arranged on the cover pillar supporting leg of below, rear support leg top rail two ends; In the middle of on the rear support leg top rail position by the oil cylinder free bearing, be hinged with one can around hinge do 180 ° rotatablely move be used to promoting the rear support leg top rail, along contact beam after rear girder horn, make the sideslip oil cylinder of left and right transverse shifting, the two ends of contact beam respectively are provided with an oil cylinder free bearing that can combine or separate with the sideslip oil cylinder piston rod end respectively by connecting bearing pin after the girder horn.The method be slidably connected of the present invention can move laterally along rear contact beam under the prerequisite that guarantees the supporting leg strength and stiffness.
Guide and limit mechanism described in the present invention is the slippage case gland seat be fixed together by contacting beam after the both sides that are arranged on the rear support leg top rail and girder horn, and the slippage case gland be fixedly connected with slippage case gland seat forms.Two slippage case gland seats contact on beam after being welded on the beam horn, and the rear support leg top rail can pass through between two slippage case gland seats.Two slippage case glands are consolidated by bolt and two slippage case gland seats, the width of slippage case gland is greater than slippage case gland seat, can hold the rear support leg top rail, the height value that the slippage case gland connected is greater than the rear support leg top rail to the height dimension of rear support leg top rail bottom surface is 2 ~ 3mm approximately, can slide smoothly to guarantee the rear support leg top rail.
Cover pillar supporting leg described in the present invention comprises sleeve column on the mode be bolted and the supporting leg that the rear support leg top rail combines, be installed on the interior traveller of the supporting leg in sleeve column hollow posts chamber on supporting leg, the traveller arranged outside has the location lath in supporting leg, and on supporting leg, there is guide strip the inboard of sleeve column; On described supporting leg in sleeve column and supporting leg the support cylinder of traveller by the height be used to adjusting supporting leg combine, along traveller in sleeve column on supporting leg and supporting leg be provided with axially that several cooperatively interact be used to installing the pin shaft hole of support bearing pin; The lower end installed inside of traveller has lower leg assembly in supporting leg.
Device of the present invention can meet Bridge Erector when little curve bridge, by traversing rear landing leg device, realize the operating mode of feeding beam in the Bridge Erector beam, specifically: when needs are traversing to the left, can by the sideslip oil cylinder cylinder piston rod be arranged on the girder horn after contact the beam left end the oil cylinder free bearing combine, can make top rail along contact beam after rear girder horn, do the left direction transverse shifting under the sideslip oil cylinder effect, driving rear support leg.When needs are traversing to the right, only sideslip oil cylinder piston rod bearing pin need to be dismantled, sideslip oil cylinder Rotate 180 °, sideslip oil cylinder piston rod bearing pin is inserted in the oil cylinder free bearing that contact beam right-hand member after the girder horn is set, can make top rail along contact beam after rear girder horn, do the right direction transverse shifting under the sideslip oil cylinder effect, driving rear support leg.Thereby guarantee the lowest construction height of Bridge Erector, increase the safety and stability of Bridge Erector.Also can meet simultaneously and make the railway clearance requirement of Bridge Erector in erecting beam construction.
Rear landing leg device described in the present invention is when construction operation, and because sleeve column on top rail and supporting leg is with bolts, both sides also have the hinge pin axle to connect.While packing Bridge Erector, dismantle connecting bolt and inboard hinge pin axle, can dig rear landing leg device, and convenient transportation guarantees not make the Bridge Erector transportation to transfinite.The lower leg assembly of installing below traveller in supporting leg can coordinate on supporting leg traveller in sleeve column and supporting leg to adjust the height of rear support leg.
The horizontal and vertical stressed of rear landing leg device described in the present invention born by location lath and guide strip.On supporting leg, the interior traveller of sleeve column and supporting leg can be adjusted the height of supporting leg up and down by support cylinder, by supporting bearing pin, traveller in crossbeam and supporting leg is fixed; The lower leg assembly that is arranged on inboard, traveller lower end in supporting leg not only can play the effect of adjusting height of landing leg, and can make its bridge floor stressed better.
The present invention compared with prior art, has following beneficial effect:
1) solved Bridge Erector and due to the deflection of girder horn, can't realize the operating mode of feeding beam in beam when the little curve bridge of frame, working depth that so just can be when not raising girder erection by bridging machine, just can realize the operating mode of feeding beam in the Bridge Erector beam.Thereby improved the safety and reliability of Bridge Erector when construction operation.
2) type of attachment of rear support leg (No. 4 supporting legs) device adopts top rail to be connected with cover column bolt on supporting leg, both sides also have the hinge pin axle to connect, during construction, bolt connects, while packing, dismantle connecting bolt and inboard hinge pin axle, rear landing leg device is dug, not only facilitated transportation but also saved the time, can guarantee again that Bridge Erector does not transfinite simultaneously when transportation.
