Hydropower station portal crane capable of accurately positioning
The invention relates to a hydropower station portal crane capable of being accurately positioned, a row of gate grooves perpendicular to the water flow direction are formed in the upstream portion in a hydropower station, a plurality of gate chambers used for storing gate plates are arranged on top platforms of the gate grooves, and lifting lugs are installed at the upper ends of the gate plates. The gate can move between the gate groove and the gate chamber through the cart walking mechanism in cooperation with the cart moving track. The trolley frame can be matched with a trolley moving track manufactured on the large trolley through a trolley walking mechanism to move in the direction perpendicular to the large trolley moving track; the fine adjustment platform can be matched with a fine adjustment moving track arranged on the trolley frame through a fine adjustment walking mechanism to move in the direction perpendicular to the trolley moving track; the lifting winding drum is mounted on the fine adjustment platform; and the beam grabbing mechanism is connected with a steel wire rope on the lifting winding drum and is used for realizing connection between the beam grabbing mechanism and the door plate through matching of a beam grabbing hydraulic cylinder on the beam grabbing mechanism and a lifting hole of a lifting lug on the door plate.
本发明涉及一种能精准定位的水电站门机，水电站内上游一排垂直水流方向的闸门槽，闸门槽顶部平台上设有若干用于存放闸门门板的闸门门库，门板上端装有吊耳，其特征在于，包括：大车，设置于闸门槽顶部平台上，能通过大车行走机构配合大车移动轨道在闸门槽和闸门门库之间移动；小车车架，能通过小车行走机构配合制于所述大车上的小车移动轨道沿垂直大车移动轨道方向移动；微调平台，能通过微调行走机构配合制于所述小车车架上的微调移动轨道沿垂直小车移动轨道方向移动；起升卷筒，安装于所述微调平台上；抓梁机构，与所述起升卷筒上的钢丝绳相连，用于通过该抓梁机构上抓梁液压缸与门板上吊耳的吊孔配合实现抓梁机构与门板连接。
