Etc. aspect.Mountable steel bridge is also commonly used for building engineering field, and in building engineering field, mountable steel bridge is not to commonly use
In successive watercourse two sides, but the most directly it is routed on the road surface that situation is bad form road surface bridge, in order to facilitate heavy vehicle to lead to
Cross and avoid heavy vehicle to be trapped in muddy ground.
Summary of the invention
The present invention is directed to deficiency of the prior art, it is provided that a kind of Simple steel slab bridge, it is possible to occur on muddy ground
Automatically ensure bridge floor horizontal equilibrium during volt, facilitate vehicle to pass through, solve conventional ground and occur that fluctuating needs to ressemble bridge
Problem.
In order to solve above-mentioned technical problem, the present invention is addressed by following technical proposals: a kind of Simple steel slab bridge, bag
Include and on main crane span structure, described main crane span structure, be provided with support crane span structure, described main crane span structure centrage is evenly arranged with several ball-and-sockets
Groove, described supporting is provided with, on crane span structure, the hemisphere jut matched with described ball-and-socket groove, described support crane span structure is additionally provided with
There are plumb bob, described plumb bob energising, described main crane span structure be provided with several first electric cylinders and several second electric cylinders,
Described first electric cylinder and described second electric cylinder divide and are listed in described centrage both sides, and described support crane span structure is additionally provided with
First controls post and second and controls post, and described first controls post and described second controls to be respectively arranged with on post and matches with described plumb bob
First soft-touch control and second soft-touch control, described first controls the first electric cylinder described in post control and rises and described second electric cylinder
Declining, described second controls the first electric cylinder decline described in post control and described second electric cylinder rises.
In technique scheme, it is preferred that be provided with groove on described support crane span structure, be provided with logical in described groove
Electricity post hangs on described energising post with the battery connecting described energising post, described plumb bob.
In technique scheme, it is preferred that described main crane span structure both sides are provided with mud guard.
In technique scheme, it is preferred that be provided with several floorings on described support crane span structure.
In technique scheme, it is preferred that described first electric cylinder and described second electric cylinder top are provided with elasticity
Pad.
In technique scheme, it is preferred that described support crane span structure both sides are provided with protective plate.
The main crane span structure of the present invention is connected by ball-and-socket groove and hemisphere jut between crane span structure with supporting, and sets on support crane span structure simultaneously
It is equipped with the plumb bob being forever perpendicular to ground, first is set in plumb bob both sides and controls post and second control post, main crane span structure is provided with
First controls post and second controls several first electric cylinders and the second electric cylinder that post controls.If mud generation fluctuating causes main crane span structure
Tilt, then can be with main crane span structure one piece inclination at support crane span structure, now plumb bob will touch first control post or second controls post, works as line
Hammer is encountered first and is controlled to allow first control post or second control post start corresponding first electric cylinder second electric cylinder and make when post or second control post
Crane span structure level must be supported.By this method, as long as surface relief is in certain scope, it is ensured that support crane span structure level,
Vehicle is facilitated to pass through.
Compared with prior art, the invention has the beneficial effects as follows: can automatically ensure bridge floor when muddy ground occurs and rising and falling
Horizontal equilibrium, facilitates vehicle to pass through, and solves conventional ground and the problem needing to ressemble bridge that rises and falls occurs.

Detailed description of the invention
With detailed description of the invention, the present invention is described in further detail below in conjunction with the accompanying drawings.
As shown in Figure 1, Figure 2, Figure 3, Figure 4, a kind of Simple steel slab bridge, including main crane span structure 1, described main crane span structure 1
Both sides are provided with mud guard 12.Support crane span structure 2 it is provided with, if being provided with on described support crane span structure 2 on described main crane span structure 1
Dry floorings 3.Described support bridge 2 frame both sides are additionally provided with on main crane span structure 1 centrage described in protective plate 21 and uniformly set
Being equipped with several ball-and-socket grooves 11, described supporting is provided with, on crane span structure 2, the hemisphere jut 22 matched with described ball-and-socket groove 11,
The diameter of described ball-and-socket groove 11 opening, less than the diameter of described hemisphere jut 22, described support crane span structure 2 is provided with groove
23, it is provided with energising post 24 and the battery 25 connecting described energising post 24 in described groove 23, described plumb bob 4 hangs over
On described energising post 24 and plumb bob energising.Several first electric cylinder 61 and several second it are provided with on described main crane span structure 1
Electric cylinder 62, described first electric cylinder 61 and described second electric cylinder 62 points are listed in host bridge frame 1 centrage two
Side, described first electric cylinder 61 and described second electric cylinder 62 top are provided with cushion 63, described support crane span structure 2
On be additionally provided with first and control post 31 and second and control post 33, described first controls post 31 and described second controls to set respectively on post 33
Being equipped with the first soft-touch control 32 and second soft-touch control 34 matched with described plumb bob 4, described first controls post 31 and controls described
First electric cylinder 61 rise and described second electric cylinder 62 declines, described second controls post 33, and to control described first electronic
Cylinder 61 declines and described second electric cylinder 62 rises.
During use, first smooth for this steel slab bridge placement, form passage.Occurring rising and falling once ground, main crane span structure 1 can be with
Mud to subside, the support crane span structure 2 on the most main crane span structure 1 can tilt along with main crane span structure 1.It is positioned at the plumb bob supported on crane span structure 2
4 are always perpendicular to ground will not rotate with the rotation supporting crane span structure 2, and when supporting crane span structure 2 and tilting, plumb bob 4 will touch
Control post 31 to first or second controls on the first soft-touch control 32 on post 33 and second soft-touch control 34.Owing to plumb bob 4 is energized, one
Denier plumb bob 4 contacts first soft-touch control 32 and second soft-touch control 34 just can trigger first and control post 31 or second control post 33.First control
Post 31 processed controls first electric cylinder 61 rising and second electric cylinder 62 declines, and second controls post 33 and controls first electric cylinder 61 times
Fall and second electric cylinder 62 rise.Thus can keep balance according to the support crane span structure 2 that allows that plumb bob 4 is real-time, it is to avoid main crane span structure
The inclination of 1 causes the inclination of whole bridge floor.
