Self-centering pushing sliding structure of hydraulic jacking gate
The invention belongs to the technical field of water conservancy and hydropower engineering gate equipment, and particularly relates to a self-centering pushing sliding structure of a hydraulic jacking gate. The device comprises a gate, a first round surface body, a second round surface body, elastic body limiting blocks, round surface body limiting blocks and other parts, the first round surface body and the second round surface body are matched to form a sliding connection pair, the elastic body limiting blocks are located on the left side and the right side of the first round surface body, and elastic bodies are located between the elastic body limiting blocks and the first round surface body; the elastic body clamps the first round surface body under the action of the elastic body limiting block; the upper surface of the first round body is slidably connected with the lower surface of the gate; the round body limiting blocks are located on the front and rear sides of the first round body. The device can adapt to deformation caused by expansion caused by heat and contraction caused by cold or bending of the gate, can prevent the gate from generating internal stress, prevents side thrust from being generated on the oil cylinder base, and further has the effect of improving the wind-induced overturning stability of the gate. The invention has the characteristic of simple and reasonable structure.
本发明属于水利水电工程闸门设备技术领域，具体涉及一种液压顶升闸门自对中顶推滑移结构。本发明包括闸门、第一圆面体、第二圆面体、弹性体限位块及圆面体限位块等零部件，第一圆面体和第二圆面体配合组成滑动连接副，弹性体限位块位于第一圆面体左右两侧，弹性体位于弹性体限位块与第一圆面体间，在弹性体限位块的作用下弹性体卡紧第一圆面体；第一圆面体上表面与闸门下表面滑动连接；圆面体限位块位于第一圆面体前后两侧。本发明能适应闸门热胀冷缩或弯曲产生的形变，能防止闸门产生内应力，防止对油缸基座产生侧推力，本发明还具有提高闸门风致倾覆稳定性的作用。本发明具有结构简单、合理的特点。
