Overturn-preventing crawling ladder based on hydraulic mechanism
The invention belongs to the technical field of climbing tools, and particularly relates to an anti-overturning ladder stand based on a hydraulic mechanism, the anti-overturning ladder stand comprises a main body composed of side rods and cross rods, rotatable supporting leg steering machines are arranged at the bottoms of the side rods, the supporting leg steering machines are hinged to supporting legs, the number of the supporting legs is four, and the bottom of each side rod is connected with two supporting legs; the supporting legs are vertical in the initial state and are close to the side rods, and the supporting legs can be unfolded to make contact with the ground under the action of the hydraulic driving mechanism. The hydraulic driving mechanism comprises a hydraulic rod, a pedal, an oil way and a hydraulic piston, one end of the hydraulic rod is hinged to the middle of the supporting leg, the other end of the hydraulic rod is hinged to the outer side face of the side rod, the pedal is vertically arranged on the inner side face of the side rod in a sliding mode through a sliding support, and the pedal is in linkage with the hydraulic piston. Hydraulic oil is provided for the hydraulic rod to enable the supporting legs to be unfolded, and the unfolded supporting legs can be fixed under the action of the locking mechanism. According to the invention, the ladder is not easy to overturn under the condition that there is no person on the ladder, and good stability can be ensured.
本发明属于攀登工具技术领域，具体涉及一种基于液压机构的防倾覆爬梯，包括由边杆和横杆组成的主体，边杆底部设有可转动的支腿转向机，支腿转向机与支腿铰接，支腿设有四条，每个边杆底部各连接两条；支腿初始状态时为竖向且与边杆贴近，在液压驱动机构的作用下支腿可展开与地面接触；所述的液压驱动机构包括液压杆、脚踏板、油路和液压活塞，液压杆一端与支腿中部铰接，另一端与边杆外侧面铰接，脚踏板通过滑动支座竖向滑动设置在边杆内侧面，脚踏板与液压活塞联动，踩下脚踏板时液压活塞下压，为液压杆提供液压油使支腿展开，支腿展开后可在锁止机构作用下固定。本发明在没有人扶梯子的情况下，梯子不易倾覆，能够保证良好的稳定性。
