Dispersed lifting mechanism and layout method for container cranes

Abstract

The invention discloses a hoisting mechanism with distributed arrangement of a container crane and an arrangement method of the hoisting mechanism. The hoisting mechanism comprises a portal assembly, a travelling trolley, a hoisting mechanism body and a lifting appliance; the hoisting mechanism body comprises hoisting and winding gears, a dragging type fixed pulley trolley and a dragging type travelling winding gear; the hoisting and winding gears are distributed at the lower end of the portal assembly; the dragging type travelling winding gear is arranged above a main beam; and the dragging type fixed pulley trolley is correspondingly dragged by the dragging type travelling winding gear. According to the invention, all the hoisting and winding gears are correspondingly distributed at four corners of the portal assembly, and down-shift of the gravity center of the whole mechanism is realized by the position distribution of the hoisting and winding gears, thus reducing the load weight of the structure at the upper part, and realizing lightweight structure of the container portal crane; and due to reasonable arrangement, the hoisting mechanism forms multiple inverted triangles along the direction of the main beam and the direction vertical to the main beam, and due to arrangement of triangles in multiple directions, and in match with a damping pulley, the purpose of shaking prevention of all directions is realized.

Description

technical field [0001] The invention relates to the field of cranes, in particular to a lifting mechanism and arranging method thereof in a dispersed arrangement of container cranes. Background technique [0002] The traditional hoisting mechanism is composed of a trolley, a hoisting hoist system, a fixed pulley block, and a traveling system. It has a large volume and its own weight is larger than its lifting capacity, especially for container cranes. After integration, it is placed on the main girder. Unnecessary additional load is caused to the main beam. Therefore, it is particularly urgent to research and develop the construction technology and equipment of lightweight, efficient and advanced lightweight multifunctional container gantry cranes. [0003] In addition, there are unpredictable operating inertia and wind loads, which cause the spreader and container to sway back and forth in the vertical plane, and torsion and vibration in the horizontal plane. [0004] Thi...

AI Technical Summary

Problems solved by technology

[0005] Such swaying, torsion, and vibration not only directly affect the alignment time of the container during loading and unloading, but also the comfort and safety of the operation, and often cause the container to collide.

If the collision is frequent, it will have a great impact on the stability and reliability of the electrical and hydraulic systems of the railway container crane spreader
