Abstract

The invention provides a climbing crane. The climbing crane includes: a first hold hoop and a second hold hoop, one of which is connected to a crane turntable structure; power driving mechanisms, the output shafts of which are equipped with gears; a rack, which is engaged with the gears; and a guide sleeve and the guide post that are in sliding fit and are disposed on the first hold hoop and the second hold hoop respectively. Specifically, the power driving mechanisms and the rack are respectively disposed on the first hold hoop and the second hold hoop. The climbing crane provided by the invention has the advantages of large bearing capacity, and safe and reliable working at heights.

Description

technical field [0001] The present invention relates to the field of hoisting equipment, more specifically, to a climbing crane. Background technique [0002] Wind energy is a new type of renewable energy with the most mature technology and the most conditions for large-scale development in the current clean energy field. A wind turbine generally includes a tower, blades, and a fan nacelle. At present, the installation of wind power equipment is mostly completed using truck cranes or crawler cranes. With the development of larger and larger wind turbines, the height of the tower is getting higher and higher, the radius of the blades is getting bigger and bigger, and the total weight of the wind turbine cabin is getting heavier and heavier. The truck crane or crawler used to hoist the wind turbine Cranes are also getting bigger and bigger. Large-scale truck cranes or crawler cranes are bulky and complex in structure. Not only are they high in manufacturing costs, they have ...
