Abstract

The invention relates to a fan blade flat sling and an exchangeable sling. The fan blade flat sling comprises a sling chain device, a T-shaped beam lifted at the lower end of the sling chain device, and a suspender arranged on the lower part of the T-shaped beam, wherein the sling chain device is composed of a lifting ring, a sling chain hung on the lifting ring and a lifting hook; the T-shaped beam comprises a longitudinal beam and a transverse beam one end of which is connected to the middle of the longitudinal beam; a group of winding and unwinding devices are respectively arranged at two ends of the longitudinal beam; the suspender is divided into a blade tip suspender and a blade root suspender; two ends of the blade tip suspender are respectively lifted on suspension centers at the lower ends of the two groups of winding and unwinding devices; and the blade root suspender is hung on the suspension centers at the lower end of the transverse beam through a rotary pulley. The fan blade flat sling disclosed by the invention is applicable to aerial lifting, replacement, detachment and other operations of fan blades and has the advantages of low lifting cost, high efficiency, easiness and convenience in operation, wide application range and the like.

Description

technical field

[0001] The invention relates to the technical field of wind power generator blade hoisting, in particular to a hoisting tool for flat hoisting and replacement of fan blades. Background technique

[0002] For the sustainable development of energy, environmental protection and low-carbon economy, the development of clean energy is imperative. As an important part of clean energy, wind power has the characteristics of green and safe, and has been widely popularized and developed in China in recent years. The blade is the key part of the fan. Due to the limitation of the structure, the composite material must be used. It is exposed to the air for many years and is easily aged and damaged. At present, the common method of installing or repairing and replacing blades in fan operation is basically to disassemble the blades and hub of the fan as a whole, replace the blades on the ground and then install the impeller back into the fan. , mostly within 30-70m, the re...
