Abstract

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; the bridge main body fixing part is welded by a steel structure, a fixing mode of obliquely pulling an upright column, a base and a cross beam is adopted, a hydraulic cylinder for driving the upright column to stretch up and down is installed on the upright column, and the base and the ground foundation are connected into a whole; the parallel telescopic part adopts 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 the bridge upright post, and the upper end of the connecting rod structure is connected with the upper end of the hydraulic cylinder. The working principle is as follows: the hydraulic cylinder is driven to expand, the hydraulic cylinder pushes the upper end of the connecting rod structure to contract the connecting rod structure, and the folding bridge plate is contracted at the same time, so that the telescopic part of the bridge is contracted; the hydraulic cylinder is driven to retract, the hydraulic cylinder drives the upper end of the connecting rod structure to expand the connecting rod structure, and meanwhile, the folding bridge plate is expanded to achieve expansion of the telescopic part of the bridge. When the hydraulic cylinder is driven to expand in the using 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 is retracted, and then the parallel telescopic bridge is in an unfolded state, so that pedestrians and vehicles can pass through the bridge floor.

Description

Parallel telescopic bridge

The technical field is as follows:

the utility model relates to a miniature bridge structures specifically is a bridge that can parallel telescope belongs to the bridge construction field.

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 utility model adopts the technical proposal that: 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.

Description of the drawings:

the present invention will be further explained with reference to the accompanying drawings.

Fig. 1 is a diagram of the bridge expansion part of the present invention.

Fig. 2 is a diagram of the fixing part of the bridge of the present invention.

Fig. 3 is the semi-expanded schematic view of the bridge of the present invention.

Fig. 4 is the bridge of the present invention expandes the sketch map.

Fig. 5 is a schematic structural diagram of the present invention.

In the figure: 1. a bridge expansion part; 2. a bridge securing portion; 3. bridge columns; 4. a bridge foundation; 5. A bridge beam; 6. a hydraulic cylinder; 7. a connecting rod structure; 8. folding the bridge plate; 9. the upper end of the connecting rod structure; 10. the lower end of the connecting rod structure; 11. a semi-deployed state; 12. a deployed state.

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 some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to 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 implemented in other ways different from the specific details set forth herein, and one skilled in the art may similarly generalize the present invention without departing from the spirit of the present invention, and therefore the present invention is not limited to the specific embodiments disclosed below.

The utility model provides a but parallel flexible bridge, in the attached: 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 bridge telescopic part 1.

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.
