Problems solved by technology

Since there are tens of thousands of bolts that need to be pre-tightened, if this method is used to prevent counter-rotation, it will not only reduce the installation efficiency, but also increase the amount of engineering installation and delay the construction period

Abstract

The invention discloses a bolt anti-follow component. The component comprises at least two sections of lower limiting strips, wherein the lower limiting strips are butted to form an entire ring; the lower limiting strips are provided with a plurality of lower limiting holes which are uniformly distributed; both the lower limiting holes at the two ends of each lower limiting strip are half holes; transition laths perpendicular to the lower limiting strips are uniformly distributed on the inner side of the lower limiting strip; one side of the transition lath is provided with upper limiting strips perpendicular to the transition laths; the upper limiting strips are provided with upper limiting holes; and the upper limiting holes are coaxial with the lower limiting holes which are nearest to the upper limiting holes. The component has the advantages of simple structure, simple and convenient operation, high installation efficiency, easy machining and capability of solving the problem of following of the bolt and is particularly suitable for preventing the following of the bolt during the connection of a flange and a bolt.

Description

technical field [0001] The invention relates to an anti-coupling component, in particular to a bolt anti-coupling component used for connecting flange bolt groups in a wind power generating set. Background technique [0002] High-strength bolts are extremely important connectors in wind turbines, which directly affect the bearing capacity, service life and safety performance of towers, nacelles, hubs and other components. During installation and construction, a preload is required. The method of symmetrical pretightening is usually adopted: first, use an electric wrench to tighten the bolt group once, and then use a hydraulic wrench to apply torque along the flange surface to the nut. When a torque is applied with a hydraulic wrench, the bolts tend to rotate, so that the torque cannot be applied. During on-site assembly in wind farms, the phenomenon of bolt rotation often occurs. In order to solve this problem, the operator generally first clamps the bolt with an open-ende...
