The road and bridge dual-purpose portal crane comprises a supporting frame and a crane body, one end of the supporting frame is provided with an adjusting mechanism, the adjusting mechanism comprises a fixing frame fixedly arranged at one end of the supporting frame, and the other end of the fixing frame is provided with a movable groove; a supporting block is fixedly arranged on the upper side, close to the movable groove, of the other end of the fixing frame, a movable frame is movably arranged on the outer side of the supporting block, a mounting plate is fixedly arranged at one end of the movable frame, and a control plate is mounted at the other end of the mounting plate. According to the road and bridge dual-purpose portal crane, a linkage shaft is rotated to drive an adjusting rod to rotate in the inner side of a movable groove, so that an adjusting frame slides along a limiting rod, a mounting plate drives a control plate to rotate with a movable shaft as the axis, and the purpose of conveniently adjusting the angle of the control plate is achieved; therefore, the situation that a worker bows to observe the control panel is avoided.
本发明公开了一种路桥两用门式起重机,包括支撑架、起重机主体,所述支撑架的一端设置有调节机构,所述调节机构包括固定设置在支撑架一端的固定架,所述固定架的另一端开设有活动槽,所述固定架的另一端靠近活动槽的上侧固定设置有支撑块,所述支撑块的外侧活动设置有活动架,所述活动架的一端固定设置有安装板,所述安装板的另一端安装有操控板。本发明所述的一种路桥两用门式起重机,通过转动连动轴并且带动调节杆在活动槽的内侧中旋转从而使调节架沿着限定杆滑动故而使安装板带动操控板以活动轴为轴旋转达到便于调整操控板的角度的目的,从而避免工人弓腰观察操控板的情况发生。
