Hydraulic hoist for safety steel gate and control method of hydraulic hoist
The invention relates to a hydraulic hoist for a safety steel gate and a control method of the hydraulic hoist, and belongs to the technical field of water conservancy and hydropower gate engineeringinfrastructure construction. The hydraulic hoist is simple and reasonable in structure and easy to produce and manufacture, a connecting lever is firmly locked through cooperation of a special-shapedhole, a special-shaped block, a large gear ring and a follow-up pinion and double locking guarantee, and safety and reliability are achieved; through cooperation of a hydraulic telescopic rod and a telescopic gate structure, the hydraulic hoist is suitable for small farmland water conservancy and large reservoirs at the same time; and through cooperation of an upper locking hydraulic cylinder anda lower locking hydraulic cylinder, a piston rod of a driving oil cylinder is firmly locked, and braking is safe and reliable.
本发明涉及一种安全型钢闸门用液压启闭机及其控制方法，属于水利、水电闸门工程基础建设技术领域。本发明结构简单合理，生产制造容易，通过异形孔、异形块以及大齿圈、随动小齿轮的配合，双重锁紧保障，将拐臂牢牢锁定，安全可靠；通过液压伸缩杆与伸缩式闸门结构的配合，可同时适用于小型农田水利、大型水库；通过上抱死液压缸、下抱死液压缸的配合，将驱动油缸的活塞杆抱死并牢牢锁定，制动安全可靠。
