Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of shipping equipment, and particularly relates to a vertical ship lift safety lifting device. BACKGROUND

[0002] The vertical ship lift is an important component of the ship lift. It is a vertical shaft structure, usually built in water conservancy hubs and other projects. Its main function is to provide a vertical running channel for ships. During operation, horizontal tunnels or channels are excavated at the upper and lower parts of the shaft as a pilot channel and the upstream and downstream channels are connected, and the water sealing gate is arranged at the upper and lower parts of the shaft to realize the safe lifting function of the water level in the shaft. The design of the vertical ship lift needs to consider factors such as structural strength, stability, water tightness, etc., to ensure that it can safely and efficiently carry ships and complete lifting operations, which is of great significance to improve the navigation capacity in inland waterway transportation.

[0003] At present, some vertical ship lifts use the method of injecting water into the conveying shaft to help the ship move upward by the buoyancy of the water flow when transporting the ship. However, there are some problems in this process. When injecting water, the water flow is fast, which will cause strong impact on the ship, resulting in the ship shaking in the shaft. At the same time, the shaking ship is easy to rub and collide with the shaft wall. This not only may cause scratching damage to the surface of the ship, affecting the appearance and structural integrity of the ship, but also may cause a certain degree of damage to the shaft wall, reducing the service life of the vertical ship lift, increasing the maintenance cost and safety risk.

[0004] Therefore, we provide a vertical ship lift safety lifting device to solve the above problems. SUMMARY

[0005] The purpose of the present application is to provide a vertical ship lift safety lifting device, which solves the problem that the existing vertical ship lift needs to inject water into the conveying shaft to help the ship move upward by the buoyancy of the water flow when transporting the ship, but the water flow will impact the ship and the ship will rub with the shaft wall during the water injection process.

[0006] To solve the above technical problems, the present application is realized by the following technical scheme.
