Multi-stage hydraulic driving mechanism of gate hydraulic hoist

MA XIAOYAN / XUE JUAN / TAO TAO / SUN YANCHAO

The invention belongs to the technical field of hydraulic driving mechanisms, and discloses a gate hydraulic hoist multi-stage hydraulic driving mechanism which comprises a concave base frame, a top plate is fixed to the top end of the concave base frame, a first multi-stage hydraulic cylinder is installed on the upper end face of the top plate, and a first connecting plate is installed at the output end of the first multi-stage hydraulic cylinder. By additionally arranging a movable strip, a connecting rod, a through hole and the like, when the first multi-stage hydraulic cylinder and the gate are installed in a butt joint mode, the first connecting plate can be moved downwards firstly, so that a connecting block and the movable strip are embedded into an embedding groove, and then the first connecting plate and the movable strip are inserted into the embedding groove; the first multi-stage hydraulic cylinder is arranged in the groove, then the movable strip provided with the first through hole is rotated and rotated into the groove, the movable strip can be preliminarily limited and fixed, then the fastening screw penetrates through the second through hole for positioning, rapid screwing of multi-stage hydraulic pressure is facilitated, and butt joint installation of the first multi-stage hydraulic cylinder and the gate is convenient and rapid.

本发明属于液压驱动机构技术领域，且公开了一种闸门液压启闭机多级液压驱动机构，包括凹型基架，所述凹型基架的顶端固定有顶板，所述顶板的上端面安装有第一多级液压缸，所述第一多级液压缸的输出端部安装有第一连接板，可在凹型基架内上下移动的闸门，所述闸门的顶端固定有第二连接板本发明通过增设活动条、连接杆和通孔等，在对接安装第一多级液压缸和闸门时，可先将第一连接板下移，使连接块和活动条嵌入至嵌槽内，然后转动开设有第一通孔的活动条，将活动条转动至凹槽内，即可初步限位固定住，然后再将紧固螺丝穿过第二通孔进行定位即可，利于多级液压的快速旋拧，使得第一多级液压缸和闸门的对接安装方便快捷。
