Specific embodiment
With reference to Fig. 1~Fig. 9, the present invention be it is a kind of set up convenient level bridges, can including a pedestal 1, winding plant 2, one
The door frame 3 of rotation and folding first pontic 4, the door frame 3 is L-shaped, is provided on first pontic 4 and controls the of its folding and unfolding
One driving device, the first pontic 4 are located on door frame 3 after folding and door frame 3 can be followed to be moved to vertical state, the first pontic 4
Lower end is pivotally connected with door frame 3, and winding plant 2 is arranged on pedestal 1, and winding plant 2 includes hawser 5,5 pile warp door frame 3 of hawser and the
One pontic 4 connects；Pedestal 1 uses vehicle-mounted form in the present embodiment, and fast and easy is moved to the position for needing to build bridge, the base
Boat-carrying form also can be used in seat 1；Wherein first driving means are preferably arranged to one first oil cylinder, it can also be that motor drives certainly
Dynamic link mechanism or other concrete forms.The present invention using the above structure drives the first pontic 4 by first rotating door frame 3
Vertical state is gone to, then, first driving means drive the first pontic 4 to gradually spread out, and while expansion, winding plant 2 is protected
It holds setting speed and releases hawser 5, control the decrease speed of the first pontic 4, so realize the fast erecting of the first pontic 4.This hair
Bright simple in structure, transport sets up very convenient, significant effect.
As shown in figs 2-4, a lifting cylinder 6 is provided on pedestal 1,6 one end of lifting cylinder is pivotally connected with pedestal 1, another
End is pivotally connected with door frame 3；An installing plate is provided on pedestal 1, installing plate is provided with an elongated hole 7, is slideably set in elongated hole 7
A shaft 8 is equipped with, which is fixedly connected with door frame 3；2 initial state of winding plant is located above 3 side of door frame so as in door frame
3 start to provide power during rotation.Initial state, shaft 8 are located at the left end of elongated hole 7, and when needing expansion, lifting cylinder 6 drives
Door frame 3 moves to right so that shaft 8 is moved to the right end of elongated hole 7, can increase the effective arm of lifting cylinder 6, in lifting cylinder 6
While promotion, winding plant 2 works together, and power is provided for the rotation of door frame 3, effective when being started to work due to lifting cylinder 6
Arm of force very little, the power that winding plant 2 provides can play the effect of stable rotation door frame 3, and the negative of lifting cylinder 6 is greatly decreased
It carries, when 3 bottom sidewall of door frame turns to parallel with hawser 5, winding plant 2 no longer provides power for the rotation of door frame 3, at this time
The rotation of door frame 3 is driven completely by lifting cylinder 6, until door frame 3 reaches vertical state.
As shown in Fig. 2, Fig. 5-Fig. 9, the invention also includes folding second pontic 9, it is provided on second pontic 9
The second driving device of its folding and unfolding is controlled, the second pontic 9 is located at the side of the first pontic 4, is provided on pedestal 1 for the second pontic
9 tracks slid laterally；In the present embodiment, the second driving device is set as one second oil cylinder, it can also be electricity certainly
Machine drive link mechanism or other concrete forms.Second pontic 9 and the second pontic 9 set up to reduce single and set up and pair set step by step
Standby high request, while in present embodiment, the structure of the second pontic 9 causes its second pontic 9 relative to existing structure
Set up it is very convenient, it is specific as follows, when door frame 3 goes to vertical state, by first driving means drive the first pontic 4 slightly
Stop after micro- expansion so that 3 and first pontic 4 of door frame can rely on winding plant 2 to keep stable state, at this point, by lifting cylinder 6
It is removed with the connection relation of door frame 3 so that the second pontic 9 can move to the initial position of the first pontic 4, treat that the second pontic 9 moves
After moving in place（Second pontic 9 is as the counterweight for setting up the first pontic 4, with the entire erection process of stabilization）, again by lifting cylinder 6
It is connect with door frame 3, then first driving means continue to drive, winding plant 2 keeps setting speed to release hawser 5, controls the first bridge
The decrease speed of body 4 is completed until the first pontic 4 is set up, and the connection of 5 and first pontic 4 of hawser is then released, by 5 pile warp of hawser
Door frame is connect behind 3 top with the bottom of the second pontic 9, and then winding plant 2 starts to shrink at hawser 5, and the second pontic 9 is driven to slide to
The top of first pontic 4, sliding rail is provided therebetween, until the second pontic 9 is slided to completely on the first pontic 4, release hawser 5 with
Hawser 5 is connect by the connection of 9 bottom of the second pontic with the top of the second pontic 9, and the second driving device, which is started to work, drives second
Pontic 9 is unfolded, and 9 expansion process of the second pontic is controlled steadily to carry out by winding plant 2, until after the second pontic 9 is fully deployed, solution
Except the connection on 5 and second pontic of hawser, 9 top, the first pontic 4 and the second pontic 9 are pivotally connected in side, and by hawser 5 and second
The side wall connection far from pivot joint side, winding plant 2 shrink hawser 5, the second pontic 9 are driven to overturn so that the second pontic on pontic 9
9 are turned to the first pontic 4 parallel, you can complete the erection of the second pontic 9.
Above-described embodiment is the preferred embodiment of the present invention, and the present invention can also have other embodiments.The technology of this field
Personnel can also make equivalent variations or replacement under the premise of without prejudice to spirit of the invention, these equivalent modifications or replacement are wrapped
It is contained in the range set by the application claim.
