The invention discloses a double-lifting type container crane and a working method thereof, and relates to the technical field of cranes. The double-lifting type container crane comprises a portal frame, double-lifting type trolleys are installed on the upper side of the portal frame; two hooks are installed at the output ends of the double-lifting type trolleys; a protection frame is installed at the portion, between the two hooks, inside the double-lifting type trolleys; a locking frame is installed between the two hooks and comprises a first telescopic frame; the upper side of the first telescopic frame is fixedly connected with a fixing frame; and the inside of the fixing frame is slidably connected with a second telescopic frame. According to the double-lifting type container crane and the working method thereof, the two trolleys are adjusted through a driving air cylinder, then the distance between the two trolleys is conveniently adjusted, thus the double-lifting type container crane can adapt to objects of different sizes, and the stability when the objects are lifted can be improved; and meanwhile, the locking frame is arranged between the two hooks, the stability between the two hooks can be kept during moving, and the double-lifting type container crane can adapt to hooks with different lengths.
Description
technical field [0001] The invention relates to the technical field of cranes, in particular to a double-lift container crane and a working method thereof. Background technique [0002] The bridge crane is a lifting device that is horizontally placed over the workshop, warehouse and stockyard for material lifting. The bridge frame of the bridge crane runs longitudinally along the rails laid on the elevated sides on both sides. It can make full use of the space under the bridge frame to lift materials without being hindered by ground equipment. It is one of the most widely used and most numerous hoisting machinery. Most of the lifting components of some bridge cranes use a single component. [0003] After searching, the Chinese patent discloses a double-lift container crane running trolley and its anchoring method with the spreader (public number: CN101062746A). The patent includes: lifting pulley block, including outer block pulley block and inner block Pulley block; hange...
