Background technique
The most common prefabricated case beam of high-speed railway bridge, the mode set up after beam car transports bridge location by Bridge Erector,
It generally requires more beam cars to meet construction period under the operating condition of long-distance transportation while transporting, due to beam car and build bridge
There are matching problems for machine, change the outfit for a Bridge Erector for generally requiring centre when beam for different size beam car, general to change
Dress mode is exactly that two 450t gantry crane integrations of operation are arranged, with complete 900t box beam unload and entrucking.Such large-scale
Heavy equipment investment is more than ten million, and manufacturing cost is huge, and field work is difficult in maintenance, and hoisting and hanging risk is higher, needs a kind of letter
Easily safe changes the outfit structure to substitute.
Summary of the invention
In view of the above problems, the utility model proposes a kind of unpowered frame that changes the outfit of high speed railway box girder, high speed railway box
Beam is unpowered to change the outfit frame, it is characterised in that: includes supporting leg I and supporting leg II, driving into for beam car between supporting leg I and supporting leg II
Road, the supporting leg I and supporting leg II are drawing and pulling type liftable cabinet framework, are equipped with pin joint flange, supporting leg at the top of supporting leg I
The top of II is connected with revolution crossbeam by turning round turntable；Before beam car drives into, revolution crossbeam is located at and road parallel direction, fortune
After beam vehicle drives into, gap of the rotation revolution crossbeam across beam car and box girder body, and will revolution crossbeam and pin joint flange
It is connected；Beam car jacks up revolution upwards and crossbeam and the supporting leg I and supporting leg II of two sides is driven to rise, by setting supporting leg I with
The height of bolt and pin hole positioning support leg I and supporting leg II on supporting leg II.The utility model solves existing by above structure
Large lifting equipment present in technology is at high cost early period, and working service is difficult, the larger technical problem of hoisting and hanging risk.
To achieve the goals above, the technical solution adopted in the utility model are as follows: high speed railway box girder is unpowered to change the outfit frame,
It is characterized by comprising having supporting leg I and supporting leg II, road, the supporting leg are driven into for beam car between supporting leg I and supporting leg II
I and supporting leg II is drawing and pulling type liftable cabinet framework, and pin joint flange is equipped at the top of supporting leg I, passes through revolution at the top of supporting leg II
Turntable is connected with revolution crossbeam；Before beam car drives into, revolution crossbeam is located at and road parallel direction, after beam car drives into, rotation
Gap of the crossbeam across beam car and box girder body is turned round, and revolution crossbeam is connected with pin joint flange；Beam car to
Upper jack-up revolution crossbeam simultaneously drives the supporting leg I and supporting leg II of two sides to rise, the bolt by being arranged on supporting leg I and supporting leg II and
The height of pin hole positioning support leg I and supporting leg II.
The supporting leg I and supporting leg II is arranged in concrete foundation.
The supporting leg I and supporting leg II can be provided with multiple groups, every group of supporting leg I and supporting leg along the road that drives into of beam car
Revolution crossbeam is equipped on II.
The supporting leg I is identical with supporting leg II structure, is divided into inside and outside two box portions, and inner bin is nested in external case
In vivo, and it can rise or decline in vertical direction, the corresponding position of internal box and outer case is provided with the pin hole of vertical setting of types,
After internal box rises, corresponding pin hole is inserted by using bolt, can will be positioned between inside and outside cabinet.
The revolution beam surface upper is equipped with rubber bearing relatively at box girder body footing.
