Background art:

at present, a part of lakes, rivers and the like need to ensure the traffic of water-surface ships and also consider the traffic of pedestrians and vehicles, so that a part of openable bridges are generated, and for example, Tianjin has a plurality of openable iron bridges. However, such an iron bridge is constructed on a small river or water surface where people have little mobility and need to temporarily pass through.

The invention content is as follows:

the technical scheme adopted by the invention is as follows: provides a bridge capable of extending and retracting in parallel. This parallel telescopic bridge includes: the bridge comprises a bridge main body fixing part and a parallel telescopic part, wherein the bridge main body fixing part is welded by a steel structure and adopts a fixing mode of obliquely pulling an upright column, a base and a cross beam, the upright column is provided with a hydraulic cylinder for driving the upright column to stretch up and down, and the base is connected with a ground foundation into a whole; the parallel telescopic part adopt a connecting rod structure, the connecting rod structure is provided with a foldable bridge deck, the lower end of the connecting rod structure is connected with a bridge upright post, and the upper end of the connecting rod structure is connected with the upper end of a hydraulic cylinder.

Adopt above-mentioned technical scheme's advantage lie in that bridge main part fixed part fixes on ground basis, and is fixed firm, drives the flexible operation of the parallel flexible part of bridge through the flexible of pneumatic cylinder to reach the flexible function of bridge, the whole simple operation is high-efficient.

The specific implementation mode is as follows:

the technical solutions in the embodiments of the present invention are clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, but the present invention may be practiced in other ways than those specifically described and will be readily apparent to those of ordinary skill in the art without departing from the spirit of the present invention, and therefore the present invention is not limited to the specific embodiments disclosed below.

The invention discloses a bridge capable of extending and retracting in parallel, which is characterized in that: the bridge fixing part 2 consists of bridge upright posts 3, a bridge base 4, a bridge cross beam 5 and a hydraulic cylinder 6; the bridge foundation 4 be responsible for the fixed part of being connected with ground foundation, pneumatic cylinder 6 be responsible for the flexible drive to bridge telescopic part 1, link structure upper end 9 and pneumatic cylinder upper end 6 in the link structure 7 of bridge telescopic part 1 are linked, link structure lower extreme 10 and bridge stand 3 in the link structure 7 of bridge telescopic part 1 are linked, link structure 7 between install folding bridge plate 8 to reach the equipment of whole parallel telescopic bridge.

The working principle is as follows: the hydraulic cylinder 6 is driven to expand, the hydraulic cylinder 6 pushes the upper end of the connecting rod structure 9 to enable the connecting rod structure 7 to contract, and meanwhile, the folding bridge plate 8 contracts to achieve the contraction of the bridge telescopic part 1; the hydraulic cylinder 6 is driven to retract, the hydraulic cylinder 6 drives the upper end 9 of the connecting rod structure to expand the connecting rod structure 7, and meanwhile, the folding bridge plate 8 is expanded to achieve expansion of the telescopic part 1 of the bridge.

When the hydraulic cylinder 6 is driven to expand in the use process, the parallel telescopic bridge is in a contraction state, and the water surface ship and the like are not influenced to run in and out at the moment; the driving hydraulic cylinder 6 is retracted, and then the parallel telescopic bridge is in an unfolded state, so that pedestrians and vehicles can pass through the bridge floor.
