Problems solved by technology

[0005] At present, both of the above two anti-sway methods have the situation that the anti-sway effect is not obvious or the driver is not suitable for driving, because the anti-sway of the steel wire rope is relatively difficult for the detection and control of the change of the steel wire rope, and the mechanism has the problem of response time lag. , resulting in no obvious anti-rolling effect; while electronic anti-rolling is a kind of passive anti-rolling, it is difficult for the driver to control the state of the crane trolley, that is, the running speed and acceleration of the trolley are all controlled by electronic control technology and programs, so that The driver is not used to driving and has airsickness

Abstract

The invention provides a hoisting mechanism. The hoisting mechanism comprises a hanger, a trolley for driving the hanger to horizontally move, a hoisting device for driving the hanger to lift and a stabilizer for reducing shake of the hanger and goods; the hoisting mechanism is characterized in that the stabilizer comprises at least one parallelogram mechanism, an upper platform for connecting the parallelogram mechanism, a connecting rod for connecting the upper platform with the trolley and a damping device for stabilization, wherein one end of the damping device is connected with the trolley; the other end of the damping device is connected with the upper platform; the parallelogram mechanism comprises a plurality of rods which are hinged with one another, wherein the four adjacent hinged points form a parallelogram; one end of the parallelogram mechanism is hinged with the upper platform, and the other end of the parallelogram mechanism is hinged with the hanger; the connecting rod is connected with the upper platform and / or the trolley in a spherical manner.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a gantry crane. Background technique [0002] Gantry crane is a variant of bridge crane. In the port, it is mainly used for loading and unloading operations of outdoor cargo yards, stockyard cargo, and bulk cargo. Its metal structure is like a door-shaped frame. Two legs are installed under the load-bearing main girder, and a cart is installed under the legs. The cart can walk directly on the track on the ground. A cargo lifting mechanism is also installed on the main beam, and the two ends of the main beam can have outrigger cantilever beams. Gantry cranes have the characteristics of high site utilization, large operating range, wide adaptability, and strong versatility, and are widely used in port freight yards. According to the structure of the door frame, it can be divided into gantry crane and cantilever gantry crane; according to the form of use, it can be ...
