Embodiment
The utility model is further elaborated below in conjunction with the accompanying drawings.
With reference to shown in figure 1, one embodiment of the present utility model is a kind of pushing tow available for Large-span Steel Box Beam construction
Power set, including pipe bending cylinder 1, one end of the pipe bending cylinder 1 are arranged on the end of steel box-girder 2, and the other end is arranged on oil
On cylinder counter-force seat 3, the oil cylinder counter-force seat 3 need to be arranged on slipway beam 4, and steel box-girder 2 is placed in the top of slipway beam 4.And then make steel
Box beam 2 is slided in the presence of jacking force in the top of slipway beam 4.
In the present embodiment, by the way that oil cylinder counter-force seat 3 is arranged on slipway beam 4 so that pipe bending cylinder 1 is in output power
Afterwards, counter-force backward is obtained from slipway beam 4, promotes steel box-girder 2 to be moved forward on slipway beam 4 using the counter-force backward, and
By changing 3 position on slipway beam 4 of oil cylinder counter-force seat, you can make the pushing steel box girder 2 of pipe bending cylinder 1 on slipway beam 4 not
Move forward disconnectedly, be advantageous to lift the convenience to move forward during steel box-girder 2 is constructed, aided in without the other crane gears of peripheral hardware, without
Temporary Piers are set up because steel box-girder moves forward.
Go out as shown in Figure 1, in another embodiment of the present utility model, for ease of installation oil cylinder counter-force seat 3, go back
Multiple pin shaft holes 5 can be set on above-mentioned slipway beam 4, and the mutual distance of multiple pin shaft holes 5 is disposed as it is equal, so
Oil cylinder counter-force seat 3 is arranged on slipway beam 4 by pin shaft hole 5 afterwards.And then pipe bending cylinder 1 is set to be obtained every time from slipway beam 4
Counter-force, the distance for promoting steel box-girder 2 to move forward is all equal, contributes to pushing steel box girder 2 at the uniform velocity to move forward；Foregoing multiple pins
Axis hole 5 preferably arranges when slipway beam 4 is horizontal positioned along horizontal line, is conveniently adjusted the position of oil cylinder counter-force seat 3, ensures steel box-girder
The stability of 2 lateral displacements.And oil cylinder counter-force seat 3 is installed on slipway beam 4 by inserting the latch of pin shaft hole, can also be lifted
The convenience that oil cylinder counter-force seat 3 dismounts.And oil cylinder counter-force seat 3 is just played only at the end of pipe bending cylinder 1 portion mounted thereto and made
With, therefore the quantity of the oil cylinder counter-force seat 3 on slipway beam 4 can set one or more according to being actually needed, when being arranged to multiple,
The dismounting number of oil cylinder counter-force seat 3 in work progress can be reduced.
On the other hand, referring still to shown in Fig. 1, according to another embodiment of the present utility model, pushing tow is lifted to be further
The stability of the power output of oil cylinder 1, its end can be arranged on oil cylinder counter-force seat 3, and clutch end is then arranged on steel case
The end of beam 2.
Further, a guide holder 6 can be also installed again between the output end of pipe bending cylinder 1 and the end of steel box-girder 2,
The output end with pipe bending cylinder 1, the end of steel box-girder 2 are fixedly connected the guide holder 6 respectively；It is corresponding, can also be upper
State and a power transmission bearing beam 7 is installed again between the end of guide holder 6 and steel box-girder 2；By foregoing structure, steel box-girder can be lifted
The harmony of 2 end stress, i.e., the point of pipe bending cylinder 1 is exported by power by guide holder 6 and power transmission bearing beam 7 and be converted to face output
Power, the lifting surface area of steel box-girder 2 is expanded, when the weight of steel box-girder 2 is larger, steel box-girder 2 can be ensured in this way
It can smoothly be moved forward in slipway beam 4, avoid making the end of steel box-girder 2 that depression or curved occur because of the point output power of pipe bending cylinder
Folding.
It is suitable in the utility model is used to solve technical problem more preferably your one embodiment with reference to shown in Fig. 2
The width of steel box-girder 2 is answered, slipway beam 4 can be two, then puts two slipway beams 4 respectively by above-mentioned pipe bending cylinder 1 two
The respective top of slipway beam 4 is respectively placed in the both sides of steel box-girder 2, then by two pipe bending cylinders 1, is controlling pipe bending cylinder 1
In the presence of device, synchronization telescope is realized, i.e., both obtain counter-force on respective oil cylinder counter-force seat 3 simultaneously, synchronous to steel case
The power of the end output reach of beam 2, moves forward from the both sides synchronous drive steel box-girder 2 of steel box-girder 2.
