Specific embodiment
The embodiment of the present invention is described in further detail below in conjunction with attached drawing.
Shown in Figure 1, the embodiment of the invention provides a kind of suspenders of Fast Installation prefabricated bridge, including suspender master
1, four lifting lug 2 of body and lifting component, wherein suspender main body 1 includes two girders 10 disposed in parallel and two girders of connection
10 at least two crossbeams 11, crossbeam 11 are mainly used for connecting two girders 10, guarantee the structural stability of suspender main body 1.Cause
This, it is preferred that crossbeam 11 is selected as more here, arranges between two girders 10 in Z-shaped, makes the company between two girders 10
It connects more firm, guarantees going on smoothly for hoisting process.In addition, being equipped with oblong slots 12 in one end of each girder 10, hanging
When filling the floorings of different model, according to the size of the floorings actually lifted, lifting component is located at elongate slots not
Same position meets the lifting and transhipment of the floorings of various different model sizes, simplifies device, save the cost, compared to tradition
Porous or single hole suspender, the step of enormously simplifying operation and difficulty have very strong practicability.
It is shown in Figure 1, it lifts by crane, is set in suspender main body 1 there are four lifting lug 2, four lifting lugs 2 are respectively arranged on for convenience
On one end of two girders 10, it is convenient for hoisting machine hoisting sling main body 1.Lifting component is additionally provided in suspender main body 1, specifically,
Lifting by crane component includes four sunpenders 3, and the both ends of each sunpender 3 are equipped with dismountable fastener 30, and one end of four sunpenders 3 is used
In passing through the hole for hoist on floorings to fix floorings, the other end is used for across oblong slots 12 to connect suspender main body 1, and is worn
The sunpender 3 for crossing oblong slots 12 can be moved along oblong slots 12.In lifting, floorings and suspender main body 1 are solid by the connection of sunpender 3
It is fixed, according to the size of the floorings actually lifted by crane, adjust specific location of the sunpender 3 in oblong slots 12, very good solution passes
When system lifting, a kind of suspender of model only corresponds to a kind of floorings or a limited number of several floorings, strong flexibility facilitate behaviour
Make personnel's operation.
Shown in referring to figures 1-4, each girder 10 includes two channel steels, and the web of two channel steels is affixed and welds solid
It is fixed, girder 10 is formed, the structure design of two channel steels can preferably guarantee that each girder 10 all has the preferable rigidity of structure, foot
The weight of floorings when bearing lifting is not susceptible to deform and damage.Wherein, lifting lug 2 is set on the flange plate of channel steel, is avoided
The joint face stress of two channel steels, to the full extent protects girder 10.Correspondingly, oblong slots 12 are arranged in two
The flange plate junction of channel steel, through the flange plate of two channel steels.
Further, in order to prevent during lifting, sunpender 3 moves along oblong slots 12 and skew occurs, because
This on the web phase veneer of two channel steels be equipped with fixed hole, the position of fixed hole is corresponding with oblong slots 12, and length with
Oblong slots 12 are consistent, are additionally provided with U-shaped button 31 on fixed hole, U-shaped button 31 be arranged in fixed hole and for limit sunpender 3 with
The relative movement of oblong slots 12.Specifically, U-shaped button 31 is arranged in fixed hole, is hung after sunpender 3 passes through oblong slots 12
Bar 3 is located in the U-lag of U-shaped button 31, then the fixing piece with screw structural will be used to lock the open end of U-shaped button 31, into one
Step guarantees the vertical of sunpender 3, moves left and right it not during lifting.
Further, girder 10 is equipped with the batten plate 4 being arranged along 10 length direction uniform intervals of girder, further to master
The structure of beam 10 is reinforced, and guarantees that it can carry the floorings of corresponding weight, will not due to the structure of its own is insecure shadow
Ring hoisting process.Specifically, batten plate 4 is square, the joint of the flange plate of two channel steels is fixed on by the way of welding, it is right
Structure further strengthens.
Further, since there may be gaps for the inside of girder 10, foreign matter enters the inside of girder 10 in order to prevent,
It is equipped with head plate 6 in the end of each girder 10, by its end-enclosed.
Further, it is equipped with muti-piece stiffener 5 in the junction of lifting lug 2 and girder 10, due to concentrating stress at lifting lug 2
It is bigger, in order to guarantee the structural stability of suspender main body 1,6 pieces are welded in the junction of each lifting lug 2 and girder 10
Stiffener 5, to guarantee the good connection of lifting lug 2 Yu girder 10.
Shown in Figure 3, the end of each sunpender 3 is equipped with screw thread, the sectional dimension of sunpender 3 and the size of oblong slots 12
Matching, prevents sunpender 3 to be fed through 12 thickness of oblong slots and the phenomenon that double swerve occurs, to influence the process of lifting.Specifically, tight
Firmware 30 includes nut 300 and gasket 301, is equipped with a fastener 30 at the both ends of each sunpender 3, one end of sunpender 3 need to be worn
The hole for hoist of gap bridge panel, the bottom of floorings is then located at positioned at the fastener 30 at this end, and the other end passes through the length on girder 10
Circular groove 12 is then located at the top of girder 10 positioned at the fastener 30 at this end, due in lifting, sunpender 3 and girder 10 or bridge floor
The junction stress of plate is concentrated, and stress is larger, and floorings or suspender main body 1 are destroyed in order to prevent, in nut 300 and girder 10
Or gasket 301 is equipped between floorings, it can prevent stress from excessively concentrating to a certain extent.
The present invention also provides a kind of method of the suspender of Fast Installation prefabricated bridge lifting floorings, method includes head
One end of four sunpenders 3 is first each passed through the hole for hoist on floorings to fix floorings, the other end is each passed through oval
Slot 12 connects suspender main body 1 and moves sunpender 3 along oblong slots 12 according to the size and model of the floorings actually lifted, tightens tight
Firmware 30 is fixed, and suspender main body 1 is connected and fixed with floorings and is finished, fixed by the lifting lug 2 on bridge crane vehicle and girder 10, most
Floorings are lifted to designated place, complete lifting by hoisting sling main body 1 afterwards.
The present invention is not only limited to above-mentioned preferred forms, anyone can show that other are each under the inspiration of the present invention
The product of kind form, however, make any variation in its shape or structure, it is all with identical or similar with the present invention
Technical solution, within its protection scope.
