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
The present invention relates to bridge field, especially a kind of flexible pontoon bridge that can stretch and can realize fast erecting.
Background technology
Pontoon bridge ancient times is called boat beam.It replaces bridge pier with ship boat, therefore there is the title of " floating boat ", " floating purlin ", " bridge of boats ", belongs to provisional bridge.Characteristic due to pontoon bridge, is militarily often employed, and therefore claims again on " war bridge ".
Traditional pontoon bridge all needs to have the boat that can suspend or case as supporter, and this just need to all be fixed into each supporter one, also needs supporter and pontic to fix, otherwise easily causes supporter separated with pontic, occurs dangerous.Supporter is all fixed into one, the time needing is longer, and fixed support body is also more difficult in water.Also need other equipment to transport supporter, and can only be fixed one by one, set up cumbersome.
The erection mode of tradition pontoon bridge, hindered the popularization of pontoon bridge, also by increasing other bridge, given and substitute, if can solve the problem that pontoon bridge sets up speed, just can highlight the characteristic of pontoon bridge, pontoon bridge is applied, in emergency situations, can be played the effect of fast open passway, when especially speedily carrying out rescue work, can play the effect of life passage.
Summary of the invention
The object of this invention is to provide a kind of flexible pontoon bridge, integral structure, lightweight, intensity is large, and the speed of setting up is fast, can lead to two sides, river course by fast open.
