Problems solved by technology

Mechanized bridge erection has high efficiency, fast speed, and good maneuverability. However, when severe disasters occur, the road conditions on the site are severely damaged. Mechanized bridge erection requires pretreatment of the site to meet the erection requirements, which affects the actual erection time of the mechanized bridge to a certain extent; At the same time, the bearing capacity of the road conditions in the disaster-stricken area is poor, which makes it impossible for the heavy-duty mechanized bridge to reach the rescue site immediately

Embodiment Construction

[0018] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0019] as attached figure 1 with 2 As shown, the present invention provides a modular bridge erection mechanism, which includes a support rod 1, a push rod 7, a modular bridge section 2, a rotating shaft 3, a roller 4, a roller shaft 5 and a propulsion power unit 6, wherein, The modular bridge section 2 is an integrated overall structure, and its length is greater than the width of obstacles to be crossed;

[0020] One end of the modular bridge section 2 is fixedly connected with the push rod 7, the other end of the modular bridge section 2 is hinged with the support rod 1 through the rotating shaft 3, and the roller 4 is installed on the bottom surface of the modular bridge section 2 through the roller shaft 3 , so that the modular bridge section 2 can move more conveniently under the push of the propulsion power unit 6 .

[0021] The erection process ...

Abstract

The invention discloses a modular bridge erecting mechanism, which belongs to the technical field of bridge erection equipment. The erection mechanism includes a push rod, a support rod, a modular bridge section and a propulsion power unit; one end of the modular bridge section is fixedly connected with the push rod horizontally, and the other end of the modular bridge section is movably connected with the end of the support rod, and the propulsion power The unit pushes the modular bridge section horizontally through the push rod to cross obstacles, and the support rod acts as a pivot point and auxiliary support during the spanning process. When the modular bridge section reaches the opposite bank and is placed flat, the erection is completed. The invention can quickly reach the bridge erection site without harsh geological conditions, and satisfies the needs of diversified bridge erection methods.

Description

technical field [0001] The invention relates to the technical field of bridge erection equipment, in particular to a field emergency rescue erection method and an erection mechanism of a modular bridge. Background technique [0002] When severe geological disasters and accidents cause road interruptions, the first choice is to open up material transportation roads. At present, it mainly relies on the rapid erection of mechanized bridges and the manually assembled Bailey Bridge. Mechanized bridge erection has high efficiency, fast speed, and good maneuverability. However, when severe disasters occur, the road conditions and environment on the site are severely damaged. Mechanized bridge erection requires pretreatment of the site to meet the erection requirements, which affects the actual erection time of the mechanized bridge to a certain extent; At the same time, the poor bearing capacity of the road conditions in the disaster-stricken area made it impossible for the heavy-d...
