Problems solved by technology

[0002] Some wind power bearing products on the market have hoisting holes in the design structure, which provides convenience for each process, but setting hoisting holes also reduces the strength and life of the slewing bearings
Therefore, in order to ensure the strength of wind power bearings, most of the bearings cancel the lifting holes, which brings inconvenience to product processing
Now we hoist products using the method of hanging rope string installation holes to hoist products, which is wasteful and laborious and not safe

Abstract

The invention relates to the technical field of bearing lifting, in particular to a wind power bearing lifting tool without a lifting hole. The wind power bearing lifting tool comprises a lifting ring, a lifting ring stud and a lifting ring stud insertion plate; one end of the lifting ring stud is connected with the lifting ring, the other end of the lifting ring stud penetrates an installing holeto be connected with the lifting ring stud insertion plate, the lifting ring stud insertion plate is a U-shaped plate, and the lifting ring stud penetrates the U-shaped plate sinking position to be connected with a nut. The problem that a wind power bearing without a lifting hole is difficult to lift is solved, more convenience is achieved, and the operation safety is improved.

Description

technical field [0001] The invention relates to the technical field of bearing hoisting, in particular to a wind power bearing hoisting tool without hoisting holes. Background technique [0002] Some wind power bearing products on the market have hoisting holes in the design structure, which provides convenience for each process, but setting hoisting holes also reduces the strength and life of the slewing bearing. Therefore, in order to ensure the strength of wind power bearings, most of the bearings cancel the lifting holes, which brings inconvenience to product processing. Now we hoist products using the method of sling string installation holes to hoist products, which is wasteful, laborious and unsafe. It is very necessary to design a special spreader that can solve the above problems and is easy to operate and safer. Contents of the invention [0003] In view of the defects in the prior art, the present invention provides a wind power bearing hanger without hoisting...
