Abstract

The invention discloses a shaking-preventing portal crane which comprises a moving base. A supporting frame is fixedly connected to the top of the moving base, and a cross beam is fixedly connected to the top of the supporting frame; the top of the cross beam is hollow, and a groove is formed in the top of the cross beam; and sliding rails are arranged in the groove, and rollers are connected in the sliding rails in a rolling mode. Compared with the prior art, a driving bevel gear is driven by a motor, the driving bevel gear drives a second bevel gear which drives a first bevel gear, and thus transmission of a transmission wheel is used for driving the rollers to achieve the effects that starting and stopping are stable and shaking is prevented. Through the arrangement of a telescopic frame and a steel wire rope, the effects of supporting and shaking prevention are achieved, and a fixing plate and a hook are arranged, so that the effect of fixing the hook is achieved, and the situation that a hung object shakes due to shaking of the hook is prevented. Double rows of winding wheels correspond to the single steel wire rope and are arranged on the same motor, the diameters and the rotating speeds are the same, and safety of the object in the ascending process is ensured.

Description

technical field [0001] The invention relates to the technical field of hoisting machinery, in particular to an anti-sway gantry crane. Background technique [0002] Gantry crane is a deformation of bridge crane, also called gantry crane. It is mainly used for loading and unloading operations of outdoor cargo yards, stockyard cargoes, and bulk cargoes. Its metal structure is like a door-shaped frame. Two legs are installed under the main beam, which can directly walk on the track on the ground. 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. It can be classified according to the structure of the door frame, the form of the main girder, the structure of the main girder, and the form of use. However, the current cranes have the problem of large shaking during start-up and lifting during...
