Folding assembly type vehicle-mounted bridge

Abstract

The invention discloses a folding assembly type vehicle-mounted bridge. The folding assembly type vehicle-mounted bridge comprises multiple first bridge bodies and at least one second bridge body, wherein rails are arranged on the first bridge bodies; rollers fitting the rails are arranged at the lower parts of one ends of the second bridge bodies; and both the first bridge bodies and the second bridge bodies can be folded toward the middles through folding devices. The bridge is divided into the first bridge bodies and the second bridge bodies; as the multiple second bridge bodies serve as counterweights, the first bridge bodies are erected firstly, and then, the second bridge bodies are erected through the fit between the rails on the erected first bridge bodies and the rollers, so that the requirements for the vehicle-mounted systems for transportation and the erecting of the bridge can be largely reduced; and the erection process can be accelerated to win precious time for emergencies. The folding assembly type vehicle-mounted bridge is simple and ingenious in structure, and is high in economic value.

Description

technical field [0001] The invention relates to a foldable and assembled vehicle-mounted bridge. Background technique [0002] In some emergency situations, it is necessary to quickly build bridges on rivers or ravines. Existing rapid bridges generally use integrated bridges (with two-way passages). The bridges of this type of structure are heavy and need to be equipped with special Vehicles, this special vehicle needs to be equipped with a large number of counterweights, the purchase and long-term maintenance of this special vehicle will generate a lot of costs, and due to the large weight, the erection time of this type of bridge will also increase. Based on the above reasons, the present invention provides a foldable and assembled vehicle-mounted bridge to solve the above problems. Contents of the invention [0003] In order to solve the above problems, the present invention provides a foldable and assembled vehicle-mounted bridge. [0004] The technical solution adop...
