Description
Technical field
The present invention relates to technical field of bridge construction more particularly to a kind of push-pull device at fixed for steel bridge installation.
Background technique
Steel bridge installed top-pushing mechanism in the past, and only pipe bending cylinder, pipe bending cylinder is mounted on steel bridge, welds on top track
Push block have an effect, every one step of pushing tow welds a push block.When another steel bridge pushing tow movement, steel bridge base track snap-gauge and rail
It rigidly rubs between road, frictional force is larger, requires pipe bending cylinder to have larger jacking force when pushing tow.
The top-pushing mechanism of steel bridge installation in the past, the weldering of one step one of push block, later period also need to cut off, and working efficiency is lower；It adopts
Pushing tow is carried out with compared with large-diameter oil cylinder, increases cost, because pushing tow frictional force is larger, will increase installation security risk.Pusher
Structure low efficiency, it is at high cost, it is dangerous.
Summary of the invention
Object of the present invention is to solve the above problems, a kind of push-pull device at fixed for steel bridge installation is provided, it is simple and quick,
Efficiency is higher, and reduces security risk, securely and reliably, at low cost.
To achieve the goals above, the technical scheme is that
A kind of push-pull device at fixed for steel bridge installation, including being set to the oil cylinder seat at steel bridge both ends, hinged with oil cylinder seat
The rear end of oil cylinder, the rail clamping device being set on track, the rail clamping device and oil cylinder is hinged；The steel bridge bottom is equipped with several
Walker, the walker are equipped with the idler wheel that can be walked in orbit.
Further, the oil cylinder seat is welded on steel bridge.
Further, the oil cylinder seat and oil cylinder are hinged by the first pin shaft, and the rail clamping device and oil cylinder pass through the second pin
Axis is hinged.
Further, one of oil cylinder is to draw oil cylinder, another is push oil cylinder.
The working principle of the invention is such that the oil cylinder being arranged before and after steel bridge is respectively to push away, draw oil cylinder, pushes away, draws oil cylinder
It is mounted on steel bridge end, pushes away, the oil cylinder other end is drawn to connect rail clamping device, rail clamping device sticks track installation, rail clamping device adjustable-tightness,
With track by self-locking clamping (oil cylinder power is bigger, rail clamping device card tighter), rail clamping device is realized and track by the way that oil cylinder is flexible
It unclamps and clamps.Steel bridge bottom is equipped with idler wheel, and steel bridge moving resistance is smaller.When work, front end oil cylinder is drawn forward, rear end oil cylinder
To being pushed forward, steel bridge is moved in orbit by idler wheel.The device pushes away in steel bridge moving process, draws operation of oil cylinde simple and fast,
Efficiency is higher, and steel bridge front and back ends are fixed using rail clamping device, securely and reliably.Because steel bridge is mobile by idler wheel, resistance is smaller, to pushing away, draw
Cylinder thrust is of less demanding, reduces costs, and reduces security risk.
Compared with prior art, the advantages and positive effects of the present invention are:
Push-pull device at fixed for steel bridge installation of the invention, it is easy to operate, high-efficient, safe.
Detailed description of the invention
In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, to embodiment or will show below

To obtain other drawings based on these drawings.
Fig. 1 is steel bridge erecting bed schematic diagram；
Fig. 2 is structural schematic diagram of the invention；
Fig. 3 is the oil cylinder attachment structure schematic diagram for making pushing action；
Fig. 4 is push-pull device at fixed working state schematic representation one,
Fig. 5 is push-pull device at fixed working state schematic representation two；
Fig. 6 is push-pull device at fixed working state schematic representation three.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment, any modification, equivalent replacement, improvement and so on should all be included in the protection scope of the present invention.
Fig. 1 is steel bridge erecting bed schematic diagram, wherein 1 is steel bridge, 2 be track, and 3 be track support frame, and 4 is under tracks
River.
Fig. 2 is that the part in the structural schematic diagram and Fig. 1 of the push-pull device at fixed for steel bridge installation of the invention at A is put
Big figure, Fig. 3 are the oil cylinder attachment structure schematic diagram that pushing action is made in left side, wherein left side is pushes operation, oil cylinder is push oil cylinder,
Right figure is to draw oil cylinder, does pull operation.
Push-pull device at fixed for steel bridge installation of the invention, oil cylinder seat 11 and oil cylinder seat including being set to 1 both ends of steel bridge
11 hinged oil cylinders 7,8, the rail clamping device 9,10 that is set on track 2, the rail clamping device 9 and oil cylinder 7, rail clamping device 10 and oil cylinder 8
Rear end it is hinged；1 bottom of steel bridge is equipped with several walkers 5, and the walker 5, which is equipped with, to walk on track 2
Idler wheel 6.
The oil cylinder seat 11 is welded on steel bridge 1.The oil cylinder seat 11 is hinged by the first pin shaft 13 with oil cylinder 7, described
Rail clamping device 9 and oil cylinder 7 are hinged by the second pin shaft 12.One of oil cylinder 7 is to draw oil cylinder, another oil cylinder 9 is push oil cylinder.
As shown in Figure 4,5, 6, the working principle of the invention is such that the oil cylinder being arranged before and after steel bridge is respectively to push away, draw
Oil cylinder pushes away, oil cylinder is drawn to be mounted on steel bridge end, pushes away, the oil cylinder other end is drawn to connect rail clamping device, and rail clamping device sticks track installation, presss from both sides
Rail device adjustable-tightness, with track by self-locking clamping (oil cylinder power is bigger, rail clamping device card tighter), rail clamping device is stretched by oil cylinder
The release and clamping with track are realized in contracting.Steel bridge bottom is equipped with idler wheel, and steel bridge moving resistance is smaller.When work, front end oil cylinder
It draws forward, to being pushed forward, steel bridge is moved rear end oil cylinder in orbit by idler wheel.The device pushes away in steel bridge moving process, draws oil
Cylinder is simple and quick, and efficiency is higher, and steel bridge front and back ends are fixed using rail clamping device, securely and reliably.Because steel bridge is mobile by idler wheel,
Resistance is smaller, to pushing away, drawing cylinder thrust of less demanding, reduces costs, reduces security risk.Of the invention pacifies for steel bridge
