telescopic pontoon

Abstract

The invention relates to a telescopic floating bridge which comprises a support frame and bridge panels. The support frame comprises two rows of side frames; the side frames are connected with side frame telescopic drive devices; the two side frames are connected integrally through a transverse rod; each row of the side frame is a linked telescopic structure which is formed by sequentially hinging multiple groups of X-shaped hinged components; each component is provided with a foldable connecting rod in a connecting manner; the bridge panels are hinged to the transverse rod; the bridge panels are hinged end to end to form an integral body; the support frame in a telescopic structure is unfolded when being used and shrunk when being out of use, so that convenience is brought to transportation; the support frame can stretch out and draw back, so that the support frame is unnecessary to be set up on site, but can be set up at the usual time and directly transported to the site and unfolded for use. The telescopic floating bridge is fast in set-up speed, can open up traffic of two sides of rivers rapidly, and is suitable for rescue, and disaster relief or military affairs.

Description

technical field [0001] The invention relates to the field of bridges, in particular to a telescopic pontoon bridge capable of expanding and contracting and realizing rapid erection. Background technique [0002] Floating bridges were called boat beams in ancient times. It uses boats instead of piers, so it is called "floating", "pontoon" and "pontoon bridge", and it is a temporary bridge. Due to the characteristics of floating bridges, they are often used in military affairs, so they are also called "battle bridges". [0003] Traditional pontoon bridges all need a boat or box that can be suspended as a support body, and this requires fixing each support body as a whole, and also needs to fix the support body with the bridge body, otherwise it will easily cause the support body to separate from the bridge body, causing Danger. It takes a long time to fix the supporting body into one body, and it is also difficult to fix the supporting body in water. Other equipment is als...

AI Technical Summary

Problems solved by technology

[0006] The present invention solves the defect that the existing pontoon bridge needs to fix the suspended support body on the water surface, which takes a long time to transport and fix, and hinders the progress of bridge erection. high speed

[0007] The present invention also solves the defect that the existing pontoon bridges are connected and erected one by one, and the erection process is cumbersome. It provides a telescopic pontoon bridge with an integrated structure, and only needs to be operated at one end to complete the bridge erection, which is convenient for erection
