Embodiment Construction

[0026] Such as figure 2 , 3 7. As shown in 7, the telescopic emergency bridge of the present invention includes a transport operation vehicle 1 and a bridge main body 2 placed on a pallet 5, and also includes a lifting and telescopic bridge set between the transport operation vehicle 1 and the pallet 5. The hydraulic system 3 of the main body and the control cable system 4 arranged in the transportation work vehicle 1 for retracting and retracting the main body of the bridge;

[0027] The bridge main body 2 includes two lateral skeletons 21, which are arranged on both sides of the bridge main body 2, and are formed by connecting a plurality of movable crosses 211 through end hinges 212. Each movable cross 211 is composed of two The rods of equal length are connected by the middle hinge 213;

[0028] A plurality of cross-bars 22 parallel to each other are provided between the two lateral frames 21, and two ends of each cross-bar 22 are respectively fixedly connected with movable cr...

Abstract

The invention discloses a telescopic emergency bridge which comprises a transport operation vehicle, a bridge main body, a hydraulic system, a supporting plate and a control cable system. The bridge main body comprises two lateral frameworks which are formed by sequentially connecting multiple movable crosses through end hinges. A plurality of parallel horizontal rods are arranged between the two lateral frameworks, and the two ends of each horizontal rod are fixedly connected with the end hinges of the movable crosses at corresponding positions of the lateral frameworks. A bridge deck slab is arranged on every two adjacent horizontal rods on the lower portion of each lateral framework, a longitudinal supporting rod is arranged on every two adjacent horizontal rods on the upper portion of each lateral framework, the two ends of each lateral framework are respectively provided with a bridge end post, a telescopic device is arranged in each bridge end post and extends out of the lower end of bridge end post, and guide wheels are arranged at the lower ends of the telescopic devices. The telescopic emergency bridge is high in pertinence, low in weight, low in requirement for operation sites, high in erecting and detaching operation speed, and high in automation degree.

Description

Technical field [0001] The invention belongs to the technical field of bridge equipment, in particular to a temporary bridge with high degree of automation, quick erection and withdrawal, and emergency use. Background technique [0002] High-grade highways are one of the important supports for the rapid development of the national economy today. However, high-grade highway networks, especially important nodes such as highway bridges and transportation hubs, are extremely vulnerable to damage in modern warfare. At the same time, the world has entered a period of frequent natural disasters. When high-grade highways suddenly encounter natural disasters such as strong earthquakes, landslides, mountain torrents and mudslides, or terrorist activities and major traffic accidents, they often have serious impacts on road traffic. For example, the severe snow disaster in the south in early 2008 paralyzed nearly 20,000 kilometers of arterial roads such as the Beijing-Zhuhai Expressway. Th...
