Mechanical bridge erecting mechanism and mechanical bridge erecting vehicle and method
The invention relates to the field of engineering machinery, in particular to a mechanical bridge erecting mechanism, a mechanical bridge erecting vehicle and a mechanical bridge erecting method. Themechanized bridge erecting method translates a gantry provided with a deck assembly to a locked position in a first direction on a mounting platform, and then rotates the gantry around a hinge point of the gantry to an erection position at which the deck assembly is deployable. By means of the technical scheme, the gantry slides to the locking position firstly, movement in the sliding direction islocked, and then the gantry is turned over to be rotated to the erecting position. In this way, the gantry does not need to extend out of the mounting platform at the beginning, the gantry is leveledwith the mounting platform or contracted in the mounting platform, the gantry extends out of the mounting platform through translational motion in the first direction, and the motion distance dependson the length needed by ground supporting of the gantry and the balance gravity overturning moment needed when the bridge body is completely unfolded.
本发明涉及工程机械领域，具体地涉及一种机械化桥架设机构及机械化桥架设车辆及机械化桥架设方法。一种机械化桥架设方法将设置有桥面组件的门架在安装平台上沿着第一方向平移到锁定位置，然后将门架绕门架的铰接点转动到桥面组件能够展开的架设位置。通过上述技术方案，通过让门架先滑动到锁定位置，锁定滑动方向的运动，然后再对门架进行翻转作业让门架旋转到架设位置。这样就不需要在初始时让门架伸出安装平台，而是让门架与安装平台平齐或者缩在安装平台内通过第一方向的平移运动让门架伸出安装平台，运动距离取决于门架撑地所需要的长度和桥体架设完全展开时所需的平衡重力翻转力矩。
