Description
Technical field
The present invention relates to a kind of Simple bridge, particularly relate to a kind of mountable steel bridge.
Background technology
Mountable steel bridge is also known as Bailey bridge, this bridge makes the compositions such as light standardization truss element component and crossbeam, longeron, bridge deck, bridge chair and connector with high-strength steel, can be assembled into rapidly on the spot be applicable to the various truss bridge across footpath, load with special erection equipment.In China, early stage mountable steel bridge is mainly used in military affairs, i.e. military steel bridge, and present mountable steel bridge, except as except Combat Readiness Steel Bridge, has been widely used in the aspects such as rescue and relief work, traffic engineering, municipal hydraulic engineering, unsafe bridge reinforcing.Mountable steel bridge is also through being usually used in building engineering field, in building engineering field, mountable steel bridge is not be usually used in successive watercourse two sides, but be usually directly routed on the bad road surface of situation and form road surface bridge, pass through in order to facilitate heavy vehicle to avoid heavy vehicle to be trapped in muddy ground.
Summary of the invention
The present invention is directed to deficiency of the prior art, provide a kind of Simple steel slab bridge, can occur on muddy ground automatically ensureing bridge floor horizontal equilibrium when rising and falling, facilitate vehicle to pass through, solve ground in the past and occur rising and falling and need to ressemble the problem of bridge.
In order to solve the problems of the technologies described above, the present invention is solved by following technical proposals: a kind of Simple steel slab bridge, comprise main crane span structure, described main crane span structure is provided with support crane span structure, described main crane span structure center line is evenly provided with several ball-and-socket grooves, described support crane span structure is provided with the hemisphere jut matched with described ball-and-socket groove, described support crane span structure has also been provided with plumb bob, described plumb bob energising, described main crane span structure is 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 center line both sides, described support crane span structure is also provided with first and controls post and second control post, described first controls post and described second controls post is respectively arranged with the first soft-touch control and second soft-touch control that match with described plumb bob, the described first first electric cylinder controlled described in post control rises and described second electric cylinder declines, the described second first electric cylinder controlled described in post control declines and described second electric cylinder rises.
In technique scheme, preferably, described support crane span structure is provided with groove, be provided with energising post and the battery being communicated with described energising post in described groove, described plumb bob hangs on described energising post.
In technique scheme, preferably, described main crane span structure both sides are provided with mud guard.
In technique scheme, preferably, described support crane span structure is provided with several bridge deck.
In technique scheme, preferably, described first electric cylinder and described second electric cylinder top are provided with cushion.
In technique scheme, preferably, described support crane span structure both sides are provided with protected apron.
Be connected by ball-and-socket groove and hemisphere jut between main crane span structure of the present invention with support crane span structure, be provided with on support crane span structure forever perpendicular to the plumb bob on ground simultaneously, first is set in plumb bob both sides and controls post and second control post, main crane span structure is provided with several first electric cylinders and second electric cylinder that first controls post and the control of second control post.If mud generation fluctuating causes main crane span structure to tilt, then can tilt with main crane span structure one piece at support crane span structure, now plumb bob will touch first control post or second control post, allows first control post or second control post start corresponding first electric cylinder second electric cylinder make support crane span structure level when plumb bob encounters first control post or second controls post.By this method, as long as surface relief is in certain scope, just can ensures to support crane span structure level, facilitate vehicle to pass through.
Compared with prior art, the invention has the beneficial effects as follows: can occur on muddy ground automatically ensureing bridge floor horizontal equilibrium when rising and falling, facilitate vehicle to pass through, solve ground in the past and occur rising and falling and need to ressemble the problem of bridge.

Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the present invention is described in further detail.
As shown in Figure 1, Figure 2, Figure 3, Figure 4, a kind of Simple steel slab bridge, comprises main crane span structure 1, described main crane span structure 1 both sides is provided with mud guard 12.Described main crane span structure 1 is provided with and supports crane span structure 2, described support crane span structure 2 is provided with several bridge deck 3.Described supporting bridge 2 frame both sides are also provided with on main crane span structure 1 center line described in protected apron 21 and are evenly provided with several ball-and-socket grooves 11, described support crane span structure 2 is provided with the hemisphere jut 12 matched with described ball-and-socket groove 11, the diameter of described ball-and-socket groove 11 opening is less than the diameter of described hemisphere jut 12, described support crane span structure 2 is provided with groove 23, be provided with energising the post 24 and battery 25 being communicated with described energising post 24 in described groove 23, described plumb bob 4 hangs on described energising post 24 and plumb bob is energized.Described main crane span structure 1 is provided with several first electric cylinder 61 and several second electric cylinders 62, described first electric cylinder 61 and described second electric cylinder 62 points are listed in described main crane span structure 1 center line both sides, described first electric cylinder 61 and described second electric cylinder 62 top are provided with cushion 63, described support crane span structure 2 is also provided with first and controls post 31 and second control post 33, described first controls post 31 and described second controls post 33 is respectively arranged with the first soft-touch control 32 and second soft-touch control 34 that match with described plumb bob 4, described first control post 31 controls described first electric cylinder 61 rising and described second electric cylinder 62 declines, described second control post 33 controls described first electric cylinder 61 decline and described second electric cylinder 62 rises.
During use, first smooth for this steel slab bridge placement, form passage.Occur once ground rising and falling, main crane span structure 1 can be subside along with mud, and the support crane span structure 2 now on main crane span structure 1 can tilt along with main crane span structure 1.Be positioned at the plumb bob 4 supported on crane span structure 2 always to rotate with the rotation supporting crane span structure 2 perpendicular to ground, when supporting crane span structure 2 and tilting, plumb bob 4 will touch first and control post 31 or second and control on first soft-touch control 32 on post 33 and second soft-touch control 34.Because plumb bob 4 is energized, contact first soft-touch control 32 and second soft-touch control 34 once plumb bob 4 and just can trigger first and control post 31 or second controls post 33.First control post 31 controls first electric cylinder 61 rising and second electric cylinder 62 declines, and second control post 33 controls first electric cylinder 61 decline and second electric cylinder 62 rises.So just can support crane span structure 2 according to real-time the allowing of plumb bob 4 and keep balance, avoid the inclination of main crane span structure 1 to cause the inclination of whole bridge floor.
