Embodiment Construction

[0032] The following descriptions of various embodiments refer to the accompanying drawings to illustrate specific embodiments in which the present invention can be implemented.

[0033] Such as figure 1 and figure 2 As shown, this embodiment discloses a blade root end bolt position inspection device, the blade root end bolt position inspection device includes a mounting frame 1 and a detection flange 2, the detection flange 2 is rotatably connected to the mounting frame 1, The detection flange 2 has several detection holes 21 , and the several detection holes 21 are located on the outer edge of the detection flange 2 and penetrate through the detection flange 2 along the radial direction of the detection flange 2 . After the bolts are installed at the blade root end, when the blade root end bolt position inspection device is inspecting the blade root end bolt position, the blade is lifted to a suitable height with a sling, and the blade root end bolt position inspection dev...

Abstract

The invention discloses a blade root bolt position verifier which comprises a mounting rack and a detection flange rotationally connected to the mounting rack. The detection flange includes detectionholes, and the detection holes are positioned in the outer periphery of the detection flange and penetrate the detection flange along the radial direction of the flange. When an installation positionof a blade root bolt is qualified is verified by detecting whether the bolt can be placed into the detection hole completely, verification operation is convenient and simple, the blade quality is improved, and the blade production power can be improved.

Description

technical field [0001] The invention relates to a device for inspecting the position of bolts at the root end of blades. Background technique [0002] In the industrial production process of megawatt-level blades, megawatt-level blades can be divided into pre-embedded bolt blades and perforated T-bolt blades according to the root-end connection method. The pre-embedded bolt blade has used the root end flange during the blade forming process, and there will be no deviation in the position of the bolt installed later. However, during the drilling process of the perforated T-bolt blade, errors such as the drilling machine program or the position of the blade will directly cause the position deviation of the bolt hole and the nut hole, thereby indirectly affecting the installation position of the bolt and nut at the root end, so it is necessary Inspection to assure the position of the bolt installation. Contents of the invention [0003] The object of the present invention i...
