Wind generator tower self-elevating translation hoist hoisting system

Abstract

The invention discloses a wind generator tower self-elevating translation hoist hoisting system. The system comprises a hoisting device, a top structure, a tower rack structure and a ground anchor device, the hoisting device comprises a hoisting arm, an end beam, hydraulic hoisting racks, a lifting oil cylinder, lifting beams and lifting steel strands, the top structure comprises supporting legs, a supporting oil cylinder, a pin roll 1 and a top ring beam, the tower rack structure comprises a pedestal, tower standard knots and tower rack top knots, the ground anchor device comprises an oil cylinder bottom anchor, a ground anchor oil cylinder, a ground anchor embedded part and a ground anchor steel strand, the system also comprises an elevating device, the elevating device comprises sleeve racks, an elevating oil cylinder, a lower ring beam, a lower latch, an upper ring beam, an upper latch and tower guiding rollers. The system has the advantages of high automation degree, self-elevating installation of a tower rack, and stabilization of a hoisting tower cylinder and a fan, and solves the problems of long cycle, large workload and high cost of fan hoisting using large-tonnage crawler cranes and truck cranes at present.

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 hoisting system. 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 hi...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a self-jacking and translational crane hoisting system for wind power generation towers, which has a high degree of automation, the tower can be self-jacked and installed, and at the same time, the tower and fan equipment can be stably hoisted to solve the problem of using large-tonnage crawler cranes. There are problems such as long cycle, heavy workload, and high cost in the hoisting of the fan with the truck crane
