AI Technical Summary

Technical Problem

In hydropower station projects, the opening and closing of stacked beam gates requires the hoisting of beam segments one by one, resulting in high requirements for the structure and performance of the hoist. In addition, a gate storage slot needs to be reserved in the direction perpendicular to the water flow, resulting in a large amount of civil engineering work. Furthermore, conventional improvement solutions are costly, occupy a large area, and pose high safety risks.

Method used

Design a transfer device including a water inlet, a stacked beam gate storage area, a gantry crane track and a one-way gantry crane. Through the horizontally arranged gantry crane track and the vertically intersecting trolley track, the transfer trolley and lifting mechanism are used to realize the transfer and storage of the stacked beam gate leaves. Combined with the one-way gantry crane, the stacked beam gate leaves are centrally stored.

Benefits of technology

It reduces the amount of civil engineering work, improves operational safety and timeliness, saves project investment, and avoids the high cost and space occupation of large-span, large-capacity bidirectional gantry cranes.

Abstract

The utility model belongs to the technical field of stoplog gate opening and closing mechanism design, and particularly relates to a transfer device for stoplog gate leaves. The device comprises a water diversion hole, a stoplog gate storage area, a portal crane track and a one-way portal crane, a trolley track vertically intersected with the portal crane track is arranged in a side area of the water diversion hole, a transfer trolley is mounted on the trolley track, and the transfer trolley is provided with a power mechanism for driving the transfer trolley to reciprocate along the trolley track; a carrying platform is arranged on the transfer trolley through a lifting mechanism and used for transferring and placing stop log gate leaves. The trolley track is provided with a first end close to the portal crane track and a second end away from the portal crane track, the stoplog gate storage area is arranged at the second end of the trolley track, and storage platforms used for storing and placing stoplog gate leaves are arranged on the portions, on the two sides of the trolley track, of the stoplog gate storage area. According to the utility model, the gate leaf of the stoplog gate can be conveniently transferred in the vertical direction of the running track of the one-way portal crane.
