摘要
为了高效完成韩庄泵站水泵机组设备的吊装以及各类闸门的启闭和检修,设计了节点可旋转的轨道和有旋转机构的双向可转向门式启闭机,并进行了1.25倍额定荷载的静载试验、1.1倍额定荷载的动载试验和变轨试验,观测了门架结构的应力应变情况。结果表明:双向可转向门式启闭机门架结构的强度和刚度均满足要求;变轨操作运行平稳,满足多功能要求,提高了门式启闭机的利用率,降低了工程造价。
In order to hoist a pumping unit efficiently, and to open-close and overhaul gate efficiently, a rotation pitch point and the gate hoist with turning mechanism were designed. Based on a static load test with 1.25 times rated load and a dynamic load test with 1.1 times rated load, the stress-strain of the portal frame was studied. The results show that the strength and stiffness of the portal frame of bidirectional and turning gate hoist can be satisfactory. Transferring the rail is a smooth operation and meets muhifunctional requirements, which increases the utilization of gate hoist and reduces the project cost.
