Single rack and gear swing hydraulic cylinder composite trunnion driving hydraulic gate dam

CHENG LI / ZHANG KUNJIA / ZHANG JINBIN

The invention discloses a single-rack gear swing hydraulic cylinder composite trunnion drive hydraulic gate dam which comprises a gate dam body capable of turning over along with a bottom shaft and further comprises at least one single-rack gear swing hydraulic cylinder, and each single-rack gear swing hydraulic cylinder is provided with a shell base, a gear shaft, a locking device and a set of rack pushing hydraulic cylinders. The gear shaft is provided with a transmission gear, and the transmission gear is meshed with the rack piston; the locking device comprises a telescopic driving device and a stop block connected with the telescopic driving device, the stop block is provided with stop teeth, the transmission gear is in a limiting state when the stop teeth are meshed with the transmission gear, and the transmission gear is in a rotatable state when the stop teeth are separated from the transmission gear. A power source of the arresting device is directly connected with an oil source of the swing cylinder, control is simplified, and action is safe and reliable; long-time closing of the gate can be guaranteed through mechanical locking without power, and locking is safe; the rotation angle of the gate dam is controllable.

本发明公开了一种单齿条齿轮摆动液压缸复合支铰驱动液压闸坝，包括可随底轴翻转的闸坝，还包括至少一个单齿条齿轮摆动液压缸，所述的单齿条齿轮摆动液压缸设有壳体座、齿轮轴、锁定装置、一组齿条推动液压缸，所述的齿轮轴设有传动齿轮，所述的传动齿轮与齿条活塞啮合；所述的锁定装置包括伸缩驱动装置、与伸缩驱动装置连接的止动挡块，所述的止动挡块设有止动齿，所述的止动齿与传动齿轮啮合时传动齿轮为限位状态，所述的止动齿与传动齿轮脱离时传动齿轮为可转动状态。本发明止动装置动力源与摆动缸油源直接相连，简化了控制且动作安全可靠；通过无动力下的机械锁死能保证闸门的长时间闭合、锁紧安全；闸坝旋转角度可控。
