The invention relates to the technical field of water resources and hydropower projects, and discloses an eight-claw type special sling for a hydropower station stator maintenance platform. The eight-claw type special sling comprises a sling center body, and the sling center body is a regular octagonal barrel; first connecting pieces are welded on eight faces of the outer side of the sling centerbody, and each first connecting piece is provided with a support arm by a high-strength bolt; the eight support arms are symmetrically distributed outwards by taking a central point of the sling center body as the center, and two lower hoisting rings are welded on the lower surface of the end, far away from the sling center body, of each support arm; and an upper hoisting ring is welded on the upper surface of the end, close to the sling center body, of each support arm, and the distances between the upper hoisting rings and the sling center body are equal. According to the eight-claw type special sling for the hydropower station stator maintenance platform, the hoisting horizontal force of the stator maintenance platform is eliminated effectively, and the hoisting height requirement during hoisting of an overall platform is low; and the hoisting process is safe, stable and reliable, and the sling strength is high.
本发明涉及水利水电工程技术领域,公开了一种水电站定子检修平台的八爪型专用吊具,包括吊具中心体,吊具中心体为正八边形筒体,吊具中心体的外侧八个面上均焊接有第一连接件,每个第一连接件通过高强螺栓安装有一个支臂,八个支臂以吊具中心体的中心点为中心对称向外发散,支臂远离吊具中心体一端的下表面焊接有两个下吊环,支臂靠近吊具中心体一端的上表面上焊接有一个上吊环,上吊环到吊具中心体的距离均相等。本发明水电站定子检修平台的八爪型专用吊具,有效消除定子检修平台的吊装水平力,吊装整体平台时的吊高要求小,吊装过程安全稳定可靠,且吊具强度高。
