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

Embodiment Construction
[0051] The present invention will be further described below in conjunction with accompanying drawing.
[0052] Such as figure 1 , 2 As shown, the present embodiment provides a lightweight multifunctional container gantry crane, which includes a gantry assembly 1, a walking trolley 4 installed on the four corners of the gantry assembly 1, Complete hoisting mechanism 2, spreader 3, driver's cab 5, stairway railing 6, electrical system 7, cable reel 62, windproof anchor 63.
[0053] Such as Figure 3-6 As shown, the door frame assembly includes two door frames arranged in parallel. The door frame is composed of a main beam 8 and legs 9 at both ends of the main beam 8. The two door frames pass through the upper beam 10 and the lower beam 12. Connection, a small beam 11 can be set between the upper beam and the lower beam, the main structural form of the main beam 8 adopts a box beam cross section, with partitions and longitudinal reinforcement ribs, and ear beams are set on bo...

The invention discloses a lightweight multifunctional container portal crane and an anti-shaking method thereof. The portal crane comprises a portal assembly, walking trolleys mounted on the four corners of the portal assembly, a lifting mechanism mounted on the portal assembly and a lifting appliance and is characterized in that the lifting mechanism comprises a lifting winch mechanism, a dragging type fixed pulley trolley and a dragging type walking winch mechanism; the lifting winch mechanism is distributed at the lower end of the portal assembly, the dragging type fixed pulley trolley is matched with a main beam of the portal assembly, the dragging type walking winch mechanism is arranged above the main beam, and the dragging type fixed pulley trolley is correspondingly dragged by a dragging type walking winch; and characteristics that the triangle has stability are utilized, the characteristic of automatic balance of eccentric damping pulleys is combined, and the aim of shaking prevention of the lifting appliance of the container portal crane is achieved.
Description
technical field [0001] The invention relates to the field of cranes, in particular to a lightweight multifunctional container gantry crane and an anti-sway method thereof. 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] This swaying, ...
