Embodiment Construction
[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0033] see Figure 1-10 As shown, the present invention is a large-span container gantry crane, which includes two chassis 100, a lifting mechanism 200 is fixedly installed on the chassis 100, a top plate 300 is installed on the lifting mechanism 200, and a lateral movement mechanism 400 is slidably installed on the top plate 300. , a lifting mechanism 500 is fixedly installed between the two lateral movement mechanisms 400 . Specifically, a displace...

The invention discloses a large-span container portal crane and a working method thereof. The large-span container portal crane comprises two chassis, lifting mechanisms are fixedly mounted on the chassis; top plates are mounted on the lifting mechanisms; lateral moving mechanisms are slidably mounted on the top plates; and a hoisting mechanism is fixedly mounted between the two lateral moving mechanisms. Through the cooperative design of a gear and a toothed rail, the overall position of the lifting mechanisms, the lateral moving mechanisms and the hoisting mechanism can be adjusted, and the hoisting in a larger range can be met; through the design of limiting air cylinders and limiting blocks on the lifting mechanisms, when the crane hoists, piston rods of the limiting air cylinders can push the limiting blocks, the limiting blocks extrude the inner walls of side box bodies, then extrusion force can be reversely provided for connecting plates, further supporting is provided for the top plates through the connecting plates, and the stability of the whole crane during hoisting is guaranteed; and through the arrangement of negative suckers, it is guaranteed that containers are clamped more stably and prevented from shaking during hoisting.
Description
technical field [0001] The invention relates to the technical field of gantry crane design, in particular to a large-span container gantry crane and a working method thereof. 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. 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. [0003] The lifting span of existing container gantry cranes is not large, and the stability of the whole crane cannot be guaranteed during hoisting. At the same time, the operator needs to manually tie the steel cables to the container during hoisting, and the container cannot be lifted automatically. When the whole container is very easy to shake. Contents of the invention [0004] The purpose of the present i...
