Floating crane cargo stabilizing device

Abstract

The invention discloses a floating crane cargo stabilizing device which comprises a rotating platform, a cantilever crane supported on the rotating platform, and a cargo stabilizing mechanism arranged on the rotating platform and the cantilever crane. The cargo stabilizing mechanism comprises cargo stabilizing guide winches, a cargo stabilizing guide pulley, a cargo stabilizing pulley yoke, a cargo stabilizing guide cargo pulley and cargo stabilizing steel wire ropes, the cargo stabilizing guide winches are arranged on the rotating platform, the cargo stabilizing guide pulley is arranged in the position, close to the bottom, of a cantilever crane lower chord, a lifting hook is arranged on the lower side of the upper part of the cantilever crane, a sling load is tied in the lifting hook, the cargo stabilizing pulley yoke is arranged on the cantilever crane lower chord and located between the cargo stabilizing guide pulley and a fixing frame which is arranged in the position, close to the lifting hook, of the lower side of the upper part of the cantilever crane, the cargo stabilizing guide cargo pulley is arranged on the sling load, the cargo stabilizing steel wire ropes are arranged among the cargo stabilizing guide winches, the cargo stabilizing guide pulley, the cargo stabilizing pulley yoke and the cargo stabilizing guide cargo pulley optionally in a penetrating winding mode. According to the floating crane cargo stabilizing device provided by the invention, when sling loads of different sizes are lifted to different lift heights, cargo stabilizing can be achieved by converting different rope winding modes.

Description

Technical field [0001] The invention relates to the technical field of cranes, in particular to a cargo stabilizing device for a floating crane. Background technique [0002] Large floating crane has the characteristics of large lifting capacity and high lifting height. It is generally used for lifting operations, equipment installation, water construction and salvage operations of offshore heavy pieces. During the installation work with a floating crane, due to the influence of sea waves and wind, the installation workpiece of the floating crane will shake, especially during wind power installation, which requires higher installation and positioning. If the workpiece shakes, it will greatly affect the installation and positioning Accuracy, reduce operating efficiency. For this reason, the current common solution is: when floating cranes are installed at sea, a single cargo winch is generally used to stabilize the hoisted cargo. However, due to the long cargo stabilizing wire r...

AI Technical Summary

Problems solved by technology

When using a floating crane for installation work, due to the influence of waves and wind, the installation workpiece of the floating crane will shake, especially in wind power installations, which have higher requirements for installation and positioning. If the workpiece shakes, it will greatly affect the installation and positioning accuracy, reducing work efficiency

For this reason, the current common solution is: when the floating crane is installed at sea, a single cargo stabilization winch is generally used to stabilize the hoisted cargo. However, due to the long cargo stabilization wire rope, the cargo stabilization effect is not good when the wind is strong. ideal

In addition, in foreign countries, the running track is installed on the lower side of the jib, and the hook is stabilized by the hook stabilizing trolley mechanism. The hook stabilizing effect is better. Reduce the overall weight of the jib, which increases the cost of use
