Abstract

The invention discloses a high-strength bolt for wind power. The high-strength bolt comprises a nut, an outer threaded rod, U-shaped grooves, a first round rod, rectangular plates, hinge plates, a limiting plate, a second outer thread and a torsional spring; the coaxial outer threaded rod is arranged on the lower end face of the nut; the multiple axially-formed U-shaped grooves are formed in the surface of the outer threaded rod; each U-shaped groove is internally provided with the corresponding rectangular plate, and the rectangular plates are perpendicular to the radius of the outer threaded rod; the plane, opposite to the groove bottoms of the U-shaped grooves, of the lowermost ends of the rectangular plates is provided with the two hinge plates, and the two hinge plates are arranged on the two sides of the rectangular plates correspondingly; and the first round rod penetrates the two hinge plates, and the two hinge plates are hinged to the first round rod. According to the high-strength bolt, the uppermost ends of the U-shaped grooves and the second outer thread are completely pressed by the nut, and the U-shaped grooves are prevented from generating adverse influences on the strength of the rod body of the part, bearing pressure, of the outer threaded rod of the bolt.

Description

【Technical field】 [0001] The invention relates to the technical field of bolts, in particular to the technical field of high-strength bolts for wind power. 【Background technique】 [0002] Bolt: A mechanical part, a cylindrical threaded fastener with a nut. A type of fastener consisting of a head and a screw (a cylinder with external threads), which needs to be matched with a nut to fasten two parts with through holes. Bolts are widely used in daily life. Bolts are one of the main connecting parts of wind power installations. Wind power installations are huge in size, and the high-strength bolts used for connection are subject to high pressure, which is prone to slippage and is not easy for the safe operation of wind power installations. 【Content of invention】 [0003] The purpose of the present invention is to solve the problems in the prior art, and propose a high-strength bolt for wind power, which can make it difficult for the thread to slip, and the nut is not easy to...
