Description

Technical Field

[0001] The utility model relates to the technical field of lifting tooling, in particular to a tooling for lifting a web of a wind turbine blade. Background Art

[0002] The web of a wind turbine blade is one of the main components of a wind turbine blade. It is used to support the blade shell and bear the bending load received by the blade. It is generally composed of two prefabricated C-shaped or I-shaped webs connected in pairs and is usually lifted with a sling.

[0003] During lifting, the sling needs to be passed through the bottom of the web and bolted together with the lifting tooling. As the crane moves upward, the web is changed from a flat position to a vertical position, and then the web is transferred to the web assembly tooling for assembly. During this process, it is very easy for the sling to strangle the web flange and damage the auxiliary flange. In addition, the operation is inconvenient, the operation time is long, and the assembly efficiency is low. Utility Model Content

[0004] The utility model aims to provide a tool for lifting the web of a wind turbine blade, so as to solve the problem that lifting the web with a sling easily causes strangulation of the web flange and damage to the auxiliary flange.

[0005] In order to achieve the above-mentioned purpose, the basic scheme of the present utility model is as follows: a tool for lifting the web of a wind turbine blade, comprising a main frame, a lifting lug, a rotating assembly and a pressure block assembly, the main frame comprising a horizontal frame and a vertical frame, the vertical frame being fixed vertically downward to the edge of the horizontal frame, the lifting lug being fixed to the top of the main frame, the rotating assembly being installed vertically downward to the edge of the horizontal frame opposite to the vertical frame, the pressure block assembly comprising a pressure plate, a screw and a handle, the pressure plate and the handle being respectively installed at both ends of the screw, the screw being threadedly connected to the rotating assembly, and the screw being parallel to the horizontal frame.

[0006] Furthermore, it also includes a plurality of pads and a plurality of protective rubbers. The plurality of pads are fixed on the bottom of the side of the vertical frame facing the rotating assembly, and the plurality of protective rubbers are respectively fixed on the surfaces of the plurality of pads.

[0007] Furthermore, the rotating assembly includes a fixed shaft, a rotating drum, a limiting ring and a bracket, the fixed shaft is fixed to the lower end surface of the cross frame, the rotating drum is rotatably connected to the fixed shaft, the limiting ring is fixed to the bottom of the fixed shaft, the bracket is fixed to the rotating drum, and a threaded hole is provided at the bottom of the bracket, and the screw is threadedly connected in the threaded hole.

[0008] Furthermore, a cylinder is fixed on the pressing plate, and the cylinder is rotatably connected to the end of the screw.

[0009] Furthermore, a triangular reinforcing rib is fixed between the cylinder and the pressing plate.

[0010] Working process of this solution: At the beginning, the pressing block assembly rotates around the rotating assembly, making the screw of the pressing block assembly parallel to the vertical frame, which is convenient for moving the tooling to the installation position of the web. Subsequently, rotate the pressing block assembly again so that the pressing plate faces the web. Rotate the screw to make the pressing plate approach the web until the web is clamped. Install this tooling at intervals of 2 - 4 meters on the web. After the above operations are completed, lift the web by the lifting beam.

[0011] Beneficial effects of this solution: (1) During the lifting process of this solution, the flanging and auxiliary flange parts of the web are not stressed, which can avoid damage to the flanging and auxiliary flange of the web.

[0012] (2) This solution has a simple structure, is easy to operate, and is applicable to webs of various sizes, and can meet the use of the web in three processes: from mold lifting to trimming (flat lifting), assembly (single web vertical lifting), and bonding of webs (double web vertical lifting).

[0013] (3) The protective rubber sheet can effectively protect the surface of the web and avoid damage to the surface of the web. Description of the Drawings
