Description
Technical field
The utility model relates to a kind of large span steel truss flexible arch bridge arch rib Integral type hydraulic lifting constructing devices.
Background technique
Long Span Steel Arch Bridges erection method mostly uses cable-hoisting construction, free cantilever erection, rack construction, rotator construction at present
Deng, these methods have reached its maturity, and various construction technologies respectively have its reasonability, but construction area topography it is flat, across water channel
When region busy and high-incidence for typhoon, conventional construction technology economy and safety are poor.Therefore to the bridge of the type
Construction technology is put forward new requirements.
Utility model content
Its purpose of the utility model, which is that, provides a kind of large span steel truss flexible arch bridge arch rib Integral type hydraulic lifting construction
Device, solve it is flat, busy across water channel and when setting up Long Span Steel Arch Bridges for the high-incidence region of typhoon in construction area topography,
The poor problem of conventional construction technology economy and safety.
It adopts the technical scheme that achieve the above object, a kind of large span steel truss flexible arch bridge arch rib integrated hydraulic mentions
Constructing device is risen, including the promotion pylon being mounted on steel bridge, the promotion pylon upper end is fixedly installed with promotion platform, is promoted
Platform upper end is fixedly installed with hydraulic lifting device, and the hydraulic lifting device upper sleeve through is equipped with steel strand wires, under steel strand wires
End is connected with the suspender for lifting member.
Beneficial effect
The utility model has the following advantages that compared with prior art.
The utility model has the advantages that due to use Integral type hydraulic lifting, thus solve typhoon zone set up greatly across
Spend the rapid construction problem of steel truss flexible arch bridge；Low with low in cost, short construction period, security risk, equipment is expanded flexible
Lifting weight, span, height and area are unrestricted；Simultaneously to be elevated for structure have stress is clear, it is steady to be promoted,
Line type control is good, closure and it is in place simple the advantages that.
Detailed description of the invention
The utility model is described in further detail with reference to the accompanying drawing.
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is the utility model structural side view；
Fig. 3 is the working principle of hydraulic lifting device in the utility model；
Fig. 4 is that steel strand wires promote status diagram in the utility model；
Fig. 5 is that steel strand wires decline status diagram in the utility model；
As shown in the figure: 1. promote pylon, and 2. promote platform, and 3. hydraulic lifting devices, 4. steel strand wires oil cylinders, 5. hang
Have, 6. steel bridges, anchor on 33., 32. lift cylinders, 31. cast anchor.
Specific embodiment
With reference to the accompanying drawing, the utility model is further described.
The present apparatus includes the promotion pylon 1 being mounted on steel bridge 6, and as shown in Figure 1-Figure 3,1 upper end of promotion pylon is solid
Dingan County promotes 2 upper end of platform and is fixedly installed with hydraulic lifting device 3, wear on the hydraulic lifting device 3 equipped with platform 2 is promoted
Set is equipped with steel strand wires 4, and the lower end of steel strand wires 4 is connected with the suspender 5 for lifting member.
The hydraulic lifting device 3 includes being fixed on the lift cylinder 32 promoted on platform 2 and casting anchor 31, and casting anchor 31 is located at
The lower end of lift cylinder 32 is fixed with the upper anchor 33 that can be moved up and down with piston rod on the piston rod of the lift cylinder 32,
The upper anchor 33, lift cylinder 32, casting anchor 31 is sleeved on steel strand wires 4.
In the utility model, the pylon 1 that promoted is installed on the steel bridge 6 set up, is promoted platform 2 and is mounted on promotion pylon
1 top, hydraulic lifting device 3, which is placed on, to be promoted on platform 2, and steel strand wires 4 penetrate hydraulic lifting device 3, the connection of 4 lower end of steel strand wires
Suspender 5, suspender is fixed on the component to be promoted；The working principle of the hydraulic lifting device 3 is that lift cylinder 32 casts anchor
31 together with lift cylinder 32 bracket be fixed on promoted platform 2 on, upper anchor 33 is then fixed on the piston rod of lift cylinder 32, energy
It is enough to move up and down with piston rod；As shown in fig. 4-5, the original state of lift cylinder 32 is that upper anchor 33 is tight, casts anchor 31 tightly, is mentioned
The whole contracting cylinders of oil-lifting jar 32；When casting anchor, 31 pines, upper anchor 33 are tight, and lift cylinder 32 can hold steel strand wires 4 under the arm and rise a distance；Promote oil
After cylinder 32 stretches cylinder in place, 31 are tightly casted anchor, anchor 33 on pine carries out contracting cylinder, can return to initial position and be promoted next time；On the contrary
Action process the decline of weight then may be implemented.
In the specific implementation, in the flexible arch rib erection process of the Long Span Railway Steel Truss beam bridge in a certain typhoon zone,
Using the hydraulic CONTROLLED INTEGRAL LIFT TECHNOLOGY of the utility model, it is disposable it is whole promoted in place, promote that tonnage is big, short construction period,
It avoids the problem of typhoon period is constructed；Integral type hydraulic lifting Construction Techniques for Erection has low in cost, short construction period, safety
Risk is low, and it is unrestricted that equipment expands flexible lifting weight, span, height and area；While having to being elevated for structure
Have the advantages that stress is clear, promote that steady, line type control is good, closure and in place simple.It has been obtained in housing construction
Extensive utilization.It is also used in steel box-girder and highway steel arch bridge at present in field of bridge construction, but in rail iron
Still belong to the first time utilization in Arch Bridge Construction.
