Embodiment Construction

[0064] work process description

[0065] 1. Put the bridge car in place, put down the balance outrigger on the mobile frame, adjust the height of the guide beam support, lift a middle bridge section and place it on the guide beam sleeve through the folding arm crane, as shown in Figure 20.

[0066] 2. The chassis car is in neutral, and the horizontal pin is withdrawn through the oil cylinder. The motor pushes the chassis car forward to the front of the car, so that the mobile frame moves out of the slideway. One end of the beam sleeve is hinged with the beam of the balance outrigger, and the other end is connected with the small slideway of the erection platform by two sets of rollers to form two supporting points, that is, the entire erection platform is built. Figure 21.

[0067] 3. Put down the front balance outrigger of the folding arm crane, and adjust the height of the front and rear outriggers according to different terrains; in order to facilitate the connection of th...

Abstract

The long span bridge erecting apparatus and process belongs to the field of traffic technology, and is especially suitable for constructing military long span bridge in wartime. The long span bridge erecting apparatus consists of chassis, arm folding crane, erecting platform, leading-in girder unit, leading-in girder sheath, movable stand, chassis frame and bridge section. The long span bridge erecting apparatus has lowered erecting height, convenient transportation, composite structure and high reliability. The present invention has short construction period, low operation plane and relatively simple construction and other advantages.

Description

technical field [0001] The invention belongs to the field of transportation, and in particular relates to an erecting device and an erecting method of a long-span modular bridge, and is especially suitable for rapidly constructing long-span bridges in military wartime. Background technique [0002] Military bridges are generally composed of bridge spans, erection mechanisms, and chassis vehicles. The bridge spans are composed of two or more bridge sections. Sections are usually erected after the connection is completed on the chassis through the erection mechanism. The chassis vehicle mainly provides the transportation of bridge joints, builds a platform for erection and provides erection power. [0003] U.S. Patent No. 5,915,423 discloses a method for erecting a long-span bridge. [0004] This invention provides an erection vehicle, which includes an erection device, and the sliding frame of the erection device is stretched out backward by hydraulic control during erectio...
