Internode；
D. bridge hoisting mechanism will be moved rearwardly into end bay end, and be fixed on bridge by carriage,
Steel construction button tower and cable are lifted by bridge hoisting mechanism；
F. by carriage, by bridge hoisting mechanism, longeron moves forward along bridge structure lower end, using step C
Mode continue lifting in span remainder.
Bridge structure hanging method provided by the present invention is the bridge hoisting machine for not influencing bridge stability using weight
Structure is lifted along the traveling of longeron 5 in bridge structure lower end.The special revolution loop wheel machine of use in the prior art is in purlin
Top of the trellis will be travelled and be lifted on the upper end longeron 6 of bridge structure.Present invention reduces the work of hoisting mechanism height
Degree, while reducing the vibrations in bridge hoisting stage so that hoisting process is more safe and reliable.Common pedrail crane may be used
It is slid on longeron 5 in bridge structure lower end by carriage after being laid down track wheel, reaches operating position and hung
Dress thus greatly reduces steel truss bridge hoisting cost, shortens total period of bridge manufacture.
The skid used in the present embodiment is as shown in figure 3, include：It is hoisting mechanism bearing seat 1, driving mechanism, removable
Formula retention mechanism, position-limit mechanism.Wherein, bridge hoisting mechanism is fixed on by position-limit mechanism on hoisting mechanism bearing seat 1, lifting
For mechanism bearing seat 1 by being connect with driving mechanism with driving mechanism interface 4, hoisting mechanism bearing seat 1 passes through removable fastening machine
Structure is removably fixed with longeron 5 in bridge structure lower end.
Position-limit mechanism is multiple, and each position-limit mechanism is respectively arranged in the surrounding of hoisting mechanism bearing seat 1, wherein at least
There are one the position-limit mechanisms in direction to be set in a manner of removable or adjustable stroke on hoisting mechanism bearing seat 1.So as to bridge
Hoisting mechanism is installed.In position-limit mechanism, front limit mechanism 2-2 in 1 front of hoisting mechanism bearing seat, held in hoisting mechanism
The rear position-limit mechanism 2-3 at 1 rear portion of seat is carried, is in the structure mutually chimeric with bridge hoisting actuator base front and back ends, the present embodiment respectively
In, the position-limit mechanism in 1 front end of hoisting mechanism bearing seat is set to hoisting mechanism bearing seat 1 in a manner of adjustable stroke
On.After bridge hoisting mechanism is seated on hoisting mechanism bearing seat 1, lateral Displacement mechanism 2-1 coordinates 1 support of hoisting mechanism bearing seat
Firmly bridge hoisting mechanism prevents it from lateral shift occurs；Position-limit mechanism 2-3 blocks the rear end of bridge hoisting actuator base afterwards, prevents
Only it is deviated upwards and backwards；Front limit mechanism 2-3 is by adjusting its stroke, before so that it is blocked bridge hoisting actuator base
End, prevents it forward and offsets up, bridge hoisting mechanism is made to be fixed with skid.
Removable retention mechanism includes two groups, and two groups of removable retention mechanisms are respectively arranged in hoisting mechanism bearing seat 1
Lower section is particularly located at position corresponding with two middle longerons 5 of bridge structure lower end.Every group of removable retention mechanism is more
Set, often covering removable retention mechanism includes：Top board 3-1, lower platen 3-3, connection bolt 3-2.Top board 3-1 is set to lifting
On mechanism bearing seat 1, lower platen 3-3 is in the lower section of longeron 5 in bridge structure lower end, and lower platen 3-3 is by connecting bolt 3-2
It is removably fastenedly connected with top board 3-1.Servoboard is set between hoisting mechanism bearing seat and bridge.Driving mechanism is liquid
Driving mechanism is pressed, is mainly acted on simultaneously by two oil cylinders, ensures that equipment can be slided along fixed-direction, prevents slipping
In shift phenomenon.
The operation principle of skid is：Bridge hoisting mechanism is fixed on hoisting mechanism bearing seat 1 by position-limit mechanism
On, so that bridge hoisting mechanism longeron 5 along bridge structure lower end is slid by hoisting mechanism bearing seat 1 by driving mechanism, when
After reaching operating position, the spacing of top board 3-1 and lower platen 3-3 are reduced by connecting bolt 3-2, and equipment and bridge are locked
Tightly, it is positioned.After having lifted an internode, connection bolt 3-2 is unclamped, but is not moved out, makes in slipping lower platen 3-3 still
With connect bolt 3-2 connections, its purpose is that：On the one hand in order to avoid special circumstances occur, prevent skid and crane this
Overall offset has occurred in entirety, guarantees safe production；On the other hand, it reduces in hoisting process, the set time of skid.
It should be noted last that the above specific implementation mode is merely illustrative of the technical solution of the present invention and unrestricted,
Although being described the invention in detail with reference to example, it will be understood by those of ordinary skill in the art that, it can be to the present invention
Technical solution be modified or replaced equivalently, without departing from the spirit of the technical scheme of the invention and range, should all cover
In the scope of the claims of the present invention.
