Pontoon bridge capable of being quickly assembled and assembling method thereof

Abstract

The invention discloses a pontoon bridge capable of being quickly assembled and an assembling method thereof. The bridge comprises a bridge head unit, a bridge tail unit, a plurality of middle units and a plurality of transition plates; the middle unit comprises a first bridge body, a second bridge body, a third bridge body, a first connecting plate and a second connecting plate; the first bridgebody and the second bridge body are connected to the two sides of the third bridge body respectively. The first connecting plate is arranged on the first bridge body; a positioning hole is formed in the left end of the first connecting plate; the positioning holes are provided with inserting holes, the first connecting plates are provided with locking mechanisms above the inserting holes; the second connecting plates are arranged on the second bridge body, the right ends of the second connecting plates extend outwards to form inserting blocks, the inserting blocks are inserted into the inserting holes of the first connecting plates of the adjacent middle units, and the inserting blocks inserted into the inserting holes are locked through the locking mechanisms. The connecting process of the adjacent middle units is easy and convenient to operate, labor is saved, and the erection efficiency of the pontoon bridge is greatly improved.

Description

technical field [0001] The invention relates to the technical field of pontoon bridges, in particular to a rapidly assembling pontoon bridge and an assembling method thereof. Background technique [0002] The pontoon bridge brigade is not only a necessary force in the armed forces of various countries, but also an indispensable backup force to support civilian construction. They are mainly responsible for opening roads for frontline troops, building bridges, disaster repairs, and civil natural disasters, man-made disasters, repairs, repairs and construction tasks. [0003] The pontoon bridge is spliced ​​by several bridge sections. At present, the connection method between the bridge sections of the pontoon bridge is connected by a plug connection, that is, among two adjacent pontoon bridges, a plug-in connection is fixed on one pontoon bridge. There is another socket seat hinged on the other pontoon bridge. After the two socket sockets are accurately aligned, the two socket...

AI Technical Summary

Problems solved by technology

[0003] The pontoon bridge is spliced ​​by several bridge sections. At present, the connection method between the bridge sections of the pontoon bridge is connected by a plug connection, that is, among two adjacent pontoon bridges, a plug-in connection is fixed on one pontoon bridge. There is another socket seat hinged on the other pontoon bridge. After the two socket sockets are accurately aligned, the two sockets are riveted together through the socket shaft. In this way, each bridge section of the pontoon bridge is connected. It is time-consuming and labor-intensive to operate, and the connection efficiency is very low

For example, in the "Challenge Impossible" program broadcast by CCTV, the pontoon brigade troops used the connection method between the above-mentioned bridge sections to erect the pontoon bridge. It took nearly 26 minutes to erect the 1,100-meter pontoon bridge on the Yangtze River. The process of erection Complicated and inefficient

[0004] In addition, when the bridge sections are connected in the above-mentioned way, each bridge section is rigidly connected. Due to the complicated situation of the river or river surface and the fluctuation of the water surface, the rigid connection between the bridge sections is very easy to make The structure at the connection is damaged, and there are hidden dangers of safety accidents on the pontoon bridge
