Description
Technical field
The present invention relates to a kind of equipment for bridge construction, particularly a kind of cantilever crane set up for bridge subsection transport.
Background technology
During bridge erection is constructed, the means spliced typically by prefabricated subsection are set up；Build first
Bridge tower, completion erection is then fixedly connected with by prefabricated bridge subsection lifting and with bridge tower.Apply at present carrying out erection to bridge
In man-hour, because prefabricated subsection build is larger, bridge tower is higher, and during splicing is set up, quantities is larger, and difficulty of construction is higher,
Construction risk is higher, and the duration is longer.In bridge prefabrication section, splicing is more during setting up at present is applied using erection crane
Work, but because erection crane need to set pre-splicing field in work progress under tower, it is not only larger by the influence of topography, and high-altitude is risen
Crane operation lifting altitude is higher, pre-splicing field under tower is had a great influence during work high above the ground, working security is relatively low, while uses bridge floor
Each tie point is both needed to set construction platform when loop wheel machine carries out lifting operation, sets operation relatively complicated, causes the construction period longer.
Therefore, at present in bridge prefabrication section splicing exist during setting up loop wheel machine set difficulty is higher, section transport is relatively complicated,
The shortcomings that construction work amount is larger, difficulty of construction is higher, construction risk is higher and the duration is longer.
The content of the invention
It is an object of the present invention to provide a kind of cantilever crane set up for bridge subsection transport.The present invention is in bridge
Prefabricated subsection splice during have it is simple in construction, be easy to set up, section transport it is more convenient the advantages of, reduce construction
Quantities and the difficulty of construction, improve construction safety coefficient, and the construction period is shorter, and splicing precision is higher.
Technical scheme：A kind of bridge subsection that is used for transports the cantilever crane set up, including two be arranged in parallel
Main couple, middle cross beam is provided between main couple, is provided with lifting dolly above main couple, lifting dolly can on main couple longitudinal direction
Mobile, lower section is provided with the middle supporting leg being connected with girder in the middle part of main couple, is provided with below main couple rearward end after being connected with girder
Supporting leg, the cantilever crane also include the rear slip supporting leg being slidably connected with main couple.
In a kind of foregoing cantilever crane set up for bridge subsection transport, the lifting dolly includes upending frame, rises
Hanging dolly can walk on upending frame, realize the direction across bridge movement of lifting dolly；The lifting dolly also includes rotary hanger, revolves
Rotary lifting is connected by steel wire rope cabling with lifting dolly, and rotary hanger can carry out full circle swinging, and framework is provided with below rotary hanger
Suspender.
In a kind of foregoing cantilever crane set up for bridge subsection transport, wherein the middle cross beam is packaged type crossbeam,
Supporting leg is installed below middle cross beam both ends.
In a kind of foregoing cantilever crane set up for bridge subsection transport, the middle supporting leg and rear support leg are liftable
Supporting leg.
Compared with prior art, by supporting leg in setting and rear support leg, two are set to put down above middle supporting leg and rear support leg
Capable main couple, and lifting dolly is set above main couple, it is more convenient to build, and need to only be set in construction in steel girder joint
Steel girder and the prefabricated bridge installation of bridge subsection can be carried out by putting construction platform, reduce quantities and the construction of construction
Difficulty, and pre-splicing field can be arranged on bridge floor, it is easy to bridge prefabrication section to transport and splice, while reduce work high above the ground
Point, workmen is reduced, improve working security, reduce the construction period.
The using effect of the artificial checking cantilever crane of application, by practice of construction by cantilever crane with present frequently with bridge
Face loop wheel machine contrasts, and concrete outcome is as shown in table 1：
In summary, the present invention bridge prefabrication section splice during have it is simple in construction, be easy to set up, section transport compared with
For it is convenient the advantages of, reduce construction quantities and construction difficulty, improve construction safety coefficient, the construction period is shorter,
It is higher to splice precision.

Embodiment
The present invention is further illustrated with reference to the accompanying drawings and examples, but be not intended as to the present invention limit according to
According to.
Embodiment.A kind of cantilever crane set up for bridge subsection transport, as shown in Figure 1 to Figure 3, including two parallel
The main couple 1 of setting, middle cross beam 2 is provided between main couple 1, the top of main couple 1 is provided with lifting dolly 3, and lifting dolly 3 can be in master
Vertically moved on truss 1, the middle part of main couple 1 lower section is provided with the middle supporting leg 4 being connected with bridge floor, is provided with below the rearward end of main couple 1
The rear support leg 5 being connected with bridge floor, the cantilever crane also include the rear slip supporting leg 6 being slidably connected with main couple 1.
The lifting dolly 3 includes upending frame 7, and lifting dolly 3 can walk on upending frame 7, realizes that lifting dolly 3 is horizontal
Bridge is to movement；The lifting dolly 3 also includes rotary hanger 9, and rotary hanger 9 is connected by steel wire rope cabling with lifting dolly 3,
