Abstract

The invention discloses a gravity self-balance type emergency rehabilitation rapid self-erection bridge. The gravity self-balance type emergency rehabilitation rapid self-erection bridge comprises a bridge body mechanism, an erecting mechanism and a vehicle mounting mechanism. The bridge body mechanism comprises at least two folding bridge bodies and a middle connecting device. A rail is arranged on the upper portion of one bridge body, and rollers matched with the rail are arranged at the two ends of the rest of bridges, and the middle connecting device is arranged between two erected bridge bodies and is used for connecting the bridge bodies on the two sides. The erecting mechanism is used for erecting the bridge bodies step by step; the vehicle mounting mechanism is used for transporting and storing the bridge body mechanism and the erecting mechanism and can provide weights for the erecting mechanism in the erecting process; and the erecting mechanism comprises a foldable lifting frame and a winch mechanism. By the adoption of the structure, the bridge bodies can be mounted step by step and one by one, and the mounted bridge bodies can provide supporting for the subsequently-mounted bridge bodies; the requirement for the weights is reduced, and therefore common vehicles can be adopted in the vehicle mounting mechanism. Meanwhile, mounting is rapid and convenient, and the gravity self-balance type emergency rehabilitation rapid self-erection bridge is suitable for the heavy bridge bodies.

Description

technical field

[0001] The invention relates to a gravity self-balancing emergency quick self-erecting bridge. Background technique

[0002] In some emergency situations, it is necessary to quickly build bridges on rivers or ravines. When the bridges are longer, in order to ensure the structural strength of the bridge body, the weight of the bridge body will be larger. Equipped with a special vehicle, the special vehicle needs to be equipped with a large number of counterweights. The purchase and long-term maintenance of the special vehicle will incur a lot of costs. rise. Based on the above reasons, the present invention provides a gravity self-balancing emergency quick self-erecting bridge to solve the above problems. Contents of the invention

[0003] In order to solve the above problems, the present invention provides a gravity self-balancing emergency quick self-erecting bridge.

[0004] The technical solution adopted by the present invention to solve its technical...
