Description

Technical Field

[0001] The utility model belongs to the technical field of wind turbine blades, and particularly relates to a supporting tooling for fixing an electric heating blanket in an inner cavity when a manhole plate of a wind turbine blade is installed. Background Art

[0002] The current heating method for wind turbine blades is to directly place a hot air blower to blow hot air into the blade cavity for heating and curing. During the heating period of the hot air blower, other operations cannot be performed in the blade cavity. The hot air needs to fill the blade cavity before the manhole plate installation position starts to heat and cure, and the heating is slow, resulting in insufficient heating.

[0003] The installation of manhole plates is a critical process. If the heating is not in place during installation, the structural adhesive will not cure properly and the installation tightness will be too low. When personnel are installing blades and performing maintenance in the wind farm, there will be a great risk of them falling off and endangering personnel safety. Utility Model Content

[0004] The utility model aims to provide a supporting tool for fixing an electric heating blanket in the inner cavity of a manhole plate of a wind turbine blade when installing the manhole plate, so that the manhole plate can be heated and cured more evenly, and normal construction operations can be carried out in the inner cavity of the blade.

[0005] In order to achieve the above-mentioned purpose, the technical solution of the utility model is as follows: when the wind turbine blade manhole plate is installed, the inner cavity of the electric blanket is fixed with a support tool, comprising an upper annular support frame, a lower annular support frame, a supporting circular adjustment frame, an upper support rod, a lower support rod and an adjustment assembly; the upper annular support frame and the lower annular support frame can be combined to form a circular structure, and the upper annular support frame and the lower annular support frame are used to support the electric blanket so that the electric blanket covers the glue coating area of ​​the manhole plate; the supporting circular adjustment frame is located in the circular structure and the center of the circular structure coincides with the center of the supporting circular adjustment frame; the upper support rod Several groups are respectively provided with the upper and lower support rods, and the adjusting components correspond to the upper support rods one by one; the upper support rod is arranged on the upper side of the supporting circular adjustment frame, and the lower support rod is arranged on the lower side of the supporting circular adjustment frame; the two sides of the lower support rod respectively support the lower annular support frame and the supporting circular adjustment frame; the outer side of the upper support rod supports the upper annular support frame, and the inner side of the upper support rod is connected with the corresponding adjusting component, the adjusting component is installed on the supporting circular adjustment frame, and the adjusting component is used to adjust the distance between the upper support rod and the supporting circular adjustment frame.

[0006] Furthermore, the adjustment assembly includes a guide tube, a nut and a threaded piece, the guide tube is fixed to the supporting circular adjustment frame, the nut is fixed to the side of the guide tube away from the upper annular support frame, the threaded piece is threadedly connected to the nut, and the threaded piece can move in the guide tube; the upper support rod is slidably connected in the guide tube, and the guide tube guides the movement of the upper support rod; the end of the threaded piece is abutted against the end of the guide tube, and the threaded piece is used to push the upper support rod to move.

[0007] Furthermore, a plurality of mounting tubes matching the lower supporting rods are fixed to the lower side of the supporting circular adjustment frame, and the inner side of the lower supporting rods is fixed in the mounting tubes.

[0008] Furthermore, mounting seats are fixed to the outer sides of the upper support rod and the lower support rod, and the mounting seats are fixed to the inner sides of the upper annular support frame and the lower annular support frame.

[0010] The working principle of this technical solution is: after installing the manhole plate and applying glue, use the tooling to adjust the threaded parts so that the upper annular support frame can support the electric blanket in the inner cavity of the blade, cover the glued area of ​​the manhole plate and heat it to make it evenly heated and cured. At the same time, the inner cavity of the blade can carry out normal construction operations. After the operation is completed, the tooling can be disassembled in the inner cavity of the blade and taken out from the manhole position.

[0011] The beneficial effect of this technical solution is that it can directly heat the glue coating area of ​​the manhole plate. Compared with the hot air blower, this technical solution is not only targeted, so that the area is heated in place, but also has high heating efficiency (the method of blowing hot air increases the temperature slowly). In addition, this technical solution can perform normal construction work in the blade cavity during heating without affecting the construction progress. BRIEF DESCRIPTION OF THE DRAWINGS
