Abstract

The invention discloses a spanning self-climbing type translational crane of a wind power generation tower. The spanning self-climbing type translational crane comprises a supporting device, a lifting device and a ground anchor device and also comprises a climbing device, wherein the climbing device is fixedly arranged under the supporting device and comprises a climbing ring beam, jacking cylinders, sleeve frames, lower inserting pin cylinders and upper inserting pin cylinders; the supporting device comprises supporting legs, a supporting beam and a support; the lifting device comprises a lifting arm, a lifting cylinder and a hydraulic lifting frame; and the ground anchor device comprises a ground anchor embedded part, a ground anchor cylinder and a ground anchor steel strand. The spanning self-climbing type translational crane disclosed by the invention has the advantages that by highly-automatic operation, crane equipment can climb up and down by self and can replace a large-tonnage crawler crane or an automobile crane to lift or maintain fan equipment, so that the lifting cost is saved and the lifting efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of fan hoisting, and in particular relates to a wind power generation tower translational crane. Background technique [0002] Wind energy is an important resource to help humans reduce carbon dioxide emissions and reduce dependence on fossil fuels. To make better use of wind energy, wind turbines are the foundation. In recent years, my country has paid more and more attention to wind power projects, and the number of new power generation towers is increasing every year. The height of wind turbines is generally more than 80 meters, and a single piece of equipment is relatively heavy. At present, the hoisting method of wind turbines generally adopts large-tonnage crawler cranes or truck cranes, and cooperates with small-tonnage truck cranes to hoist the fan nacelle and blades. It is difficult to transport these large cranes to the site, and the requirements for the roads along the line are also high. The as...
