The invention relates to a protection device, in particular to an anti-tipping protection device based on a lorry-mounted crane. The invention provides an anti-rollover protection device based on a lorry-mounted crane, which is convenient to disassemble. An anti-rollover protection device based on a lorry-mounted crane comprises a supporting plate, clamping pieces and the like, and the clamping pieces are connected to the front side and the rear side of the supporting plate in a bilateral symmetry and sliding mode. The rotating nut is rotated through a wrench, the first two-way threaded rod and the second two-way threaded rod drive the two clamping pieces on the first two-way threaded rod and the second two-way threaded rod to move in the direction away from each other, the clamping pieces can loosen a frame of the vehicle, the device is not installed on the frame of the vehicle any more, and therefore the device can be detached from the vehicle through simple operation; and convenience is brought to workers.
本发明涉及一种保护装置,尤其涉及一种基于随车起重机的防倾翻保护装置。本发明提供一种方便拆卸的基于随车起重机的防倾翻保护装置。一种基于随车起重机的防倾翻保护装置,包括有支撑板、夹持件等,支撑板的前后两侧均左右对称式滑动连接有夹持件。通过扳手转动旋转螺母,使第一双向螺纹杆和第二双向螺纹杆分别带动其上的两个夹持件向相离的方向移动,夹持件会将车辆的车架松开,使本装置不再安装在车辆的车架上,以此通过简单的操作即可将本装置从车辆上卸下,给工作人员带来了便利。
