A wind turbine blade mold flipping and lifting structure

Abstract

The present invention discloses a wind turbine blade mold flipping and lifting structure, comprising a square tube component, a glass fiber reinforced plastic flange, a sling, and a tooling component. The present invention cleverly designs the tooling component, and installs the tooling component when the original glass fiber reinforced plastic flange, upper square tube, and lower square tube structures are inconvenient. The support plate is designed to be an L-shaped structure, and a plurality of round tubes are installed between the longitudinal parts of the support plate, so that the following sling path is formed: the lower side of the sling is wrapped around the bottom of the lower square tube, and the upper end of the sling penetrates into the connection channel between the support plates and extends upward around the outer sides of the plurality of round tubes, so that the entire lifting and flipping sling path is moved outward through the L-shaped support plate and the round tubes installed between the longitudinal parts of the support plate, and assembly is achieved by movably connecting the head lock and the lower square tube, so that the contact between the sling and the glass fiber reinforced plastic flange can be effectively avoided, and damage to the glass fiber reinforced plastic flange can be prevented.

Description

Technical Field

[0001] The invention relates to a wind turbine blade mould overturning and hoisting structure. Background Art

[0002] During the production process of wind turbine blade molds, it is necessary to flip 180 degrees when demoulding. The fiberglass flanges on both sides of the mold must be protected to prevent the flanges from being damaged and delaminated by the slings. There are generally two ways to protect the flanges: one is to pad wood under the flanges; the other is to weld a protective beam on the mold steel frame. Improper operation of method 1 will damage the mold due to the movement of the wood. This method has been eliminated. Method 2 can fully protect the mold flange, but the protective beam will affect the installation of the scaffolding or the movement of people on the scaffolding, so it must be removed. The removal process will cause damage to the mold steel frame; in addition, the current lifting method is to tie the sling to the sling at the bottom of the steel frame, and use a few pieces of wood to pad under the fiberglass where the sling contacts the fiberglass. The wood supports the sling so that the sling does not directly contact the fiberglass, and then directly lift it using a crane. However, in this method, the wood is easily deformed by force, or even falls off, which damages the fiberglass flange. Summary of the invention

[0003] In view of the above-mentioned deficiencies in the prior art, the present invention solves the problem of providing a wind turbine blade mold flipping and lifting structure that can effectively protect the fiberglass flange.

[0004] To solve the above problems, the technical solution adopted by the present invention is as follows:

[0005] A wind turbine blade mold flipping and lifting structure, comprising a square tube assembly, a glass fiber reinforced plastic flange, a sling, and a tooling assembly; the glass fiber reinforced plastic flange is installed on the upper end of the square tube assembly; the side of the glass fiber reinforced plastic flange protrudes from the upper outer side of the square tube assembly; the square tube assembly comprises an upper square tube and a lower square tube connected and distributed up and down; the tooling assembly comprises a bracket plate, a round tube, and a head lock; the bracket plate is in an L-shaped structure; there are two bracket plates, which are relatively parallel to each other; a connecting channel is provided between the two bracket plates; the bracket plate in an L-shaped structure comprises a longitudinal portion and a transverse portion; a plurality of round tubes are vertically installed from top to bottom between the longitudinal portions of the two bracket plates; the head lock is installed at the ends of the transverse portions of the two bracket plates; the head lock is clamped and installed on the upper square tube; the lower side of the sling is wrapped around the bottom of the lower square tube; the upper end of the sling penetrates into the connecting channel between the bracket plates and extends upward around the outer sides of a plurality of round tubes.

[0006] Furthermore, the head lock includes an inner plate, a through bolt, an outer plate, and a tightening nut; the inner plate is vertically installed at the end of the lateral part of the two bracket plates; the outer plate is arranged relatively parallel to the outer side of the inner plate; the upper square tube is passed between the inner plate and the outer plate; the upper and lower sides of the inner plate and the outer plate are locked and connected by through bolts and tightening nuts.

[0007] Furthermore, the upper end of the longitudinal portion of the L-shaped structural support plate is located outside the upper end of the fiberglass flange.

[0008] Furthermore, two round tubes are installed from top to bottom between the longitudinal parts of the two bracket plates; and the two round tubes are in different vertical directions.

[0009] Furthermore, the support plate is provided with a hollow portion.

[0010] Furthermore, the upper square tube and the lower square tube are made of metal steel plate material.

[0011] Beneficial effects of the present invention

[0012] 1. The present invention cleverly designs a tooling assembly, which is installed under the inconvenience of the original FRP flange, upper square tube, and lower square tube structure. The bracket plate is designed to be an L-shaped structure, and a plurality of round tubes are installed between the longitudinal parts of the bracket plate, thus forming the following sling path: the lower side of the sling is wrapped around the bottom of the lower square tube, the upper end of the sling penetrates into the connection channel between the bracket plates and extends upward around the outer sides of the plurality of round tubes, thus the entire lifting and flipping sling path is moved outward by the L-shaped bracket plate and the round tubes installed between the longitudinal parts of the bracket plate, and assembly is achieved by movably connecting the head lock and the lower square tube, thus effectively avoiding contact between the sling and the FRP flange, and preventing damage to the FRP flange.

[0013] 2. The head lock designed in the present invention includes an inner plate, a through bolt, an outer plate, and a tightening nut. An upper square tube is passed between the inner plate and the outer plate, and the upper and lower sides of the inner plate and the outer plate are locked and connected by the through bolt and the tightening nut, thereby realizing a movable connection, and the assembly is simple and efficient, and the operation is convenient.

[0014] 3. The upper end of the longitudinal portion of the L-shaped structural support plate of the present invention is located outside the upper end of the FRP flange, which can further expand the protection range and make the sling stay away from the FRP flange when it extends further upward, thereby ensuring that damage to the FRP flange is avoided; the present invention installs two round tubes from top to bottom between the longitudinal portions of the two support plates, and places the two round tubes in different vertical directions. In this way, when the sling moves upward, the upward pulling force can be partially decomposed into horizontal force, thereby balancing the force on the sling and improving the safety of the sling.
