Disclosure of Invention

The invention aims to overcome the defects in the prior art and provide a false flange tool for an offshore wind tower, which can meet the requirement that the diameter of a flange is in a range of 4300mm to 6500 mm; according to the field use condition, compared with the original 2-piece type false flange, the number of operation steps is reduced, the installation difficulty is obviously reduced, the use range is obviously widened, the number and the specification of the false flanges are reduced, the comparison and type selection work before the false flanges are used is omitted, and the use error rate is reduced.

In order to achieve the purpose, the technical scheme of the invention is to design a false flange tool for an offshore wind tower, which comprises a disc-shaped tool body, wherein lightening holes are arranged on the tool body in an annular array mode, and a lifting ring for lifting a flange with the diameter of below 6000mm and a lifting lug for lifting a flange with the diameter of above 6000mm are arranged on the tool body. The single false flange can bear 100 tons; according to the analysis of the lifting stress condition, 2 groups of lifting devices are designed, a lifting ring lifts a flange with the diameter of below 6000mm, and a lifting lug lifts a flange with the diameter of above 6000 mm; a large number of round steel steps, pedals and 2 crawling ladders for climbing and hanging safety belts are added, so that the convenience and safety operation of constructors are met to the greatest extent; in order to meet the requirements of 8 fixing points, 8 supporting strip structures are designed, and each supporting strip is provided with one fixing point; 3 lifting lugs for lifting and turning over the false flange are designed.

The tool body is also provided with eight support bars which are arranged in a central annular array of the tool body; eight lightening holes are formed.

The technical scheme is that the upper portion of the tool body is provided with lifting lugs for lifting and turning over the false flange, a plurality of stepping rods made of round steel are arranged in the middle area of the tool body from top to bottom at intervals, and two crawling ladders are fixedly arranged on two sides of the middle area of the tool body respectively.

A further technical scheme does, the cat ladder is including fixed two vertical posts that set up on frock body surface, the fixed pole of transversely marking time that sets up a plurality of between two vertical posts, be equipped with on the vertical post and hold the grooving, it is equipped with the elasticity rope to hold the grooving, the one end fixed connection of elasticity rope is on its inslot wall that holds the grooving of vertical post, the other end of elasticity rope exposes and holds the grooving setting and expose the end fixing that holds the grooving and set up annular spring and detain, annular spring detains and the annular spring on the protection waistband between operation workman's waist and detains looks adaptation. Due to the arrangement of the elastic rope and the annular spring buckles, an operator can protect the ladder when climbing the ladder, the situation that the rope is externally hung can be avoided due to the elastic rope, the high elastic rope climbed by the operator can be extended to be long, the elastic rope can be retracted when the operator returns to the bottom end of the ladder, and the elastic rope can be retracted when the connection state of the two annular spring buckles is released.

The invention has the advantages and beneficial effects that: due to the arrangement of the elastic rope and the annular spring buckles, an operator can protect the ladder when climbing the ladder, the situation that the rope is externally hung can be avoided due to the elastic rope, the high elastic rope climbed by the operator can be extended to be long, the elastic rope can be retracted when the operator returns to the bottom end of the ladder, and the elastic rope can be retracted when the connection state of the two annular spring buckles is released. The flange diameter can be in the range of 4300mm to 6500 mm; according to the field use condition, compared with the original 2-piece type false flange, the number of operation steps is reduced, the installation difficulty is obviously reduced, the use range is obviously widened, the number and the specification of the false flanges are reduced, the comparison and type selection work before the false flanges are used is omitted, and the use error rate is reduced.
