Abstract

The invention provides a bolt loosening prevention component and a turnout. The bolt loosening prevention component comprises a locating gasket and an anti-loosening gasket, wherein the locating gasket is arranged on a part to be fastened; at least two first limiting parts are arranged on the locating gasket; the anti-loosening gasket is arranged on the locating gasket; second limiting parts are arranged on the anti-loosening gasket; the second limiting parts are connected with the first limiting parts in a matched manner, wherein through a bolt and a nut, the locating gasket is fixed on the part to be fastened; the anti-loosening gasket sleeves the nut; and the first limiting parts and the second limiting parts are connected with each other. The anti-loosening gasket is located on the locating gasket through the first limiting parts and the second limiting parts, and the nut is located on the anti-loosening gasket so as to guarantee that the nut can be always in a fastened state in the working process. By arranging at least two groups of the first limiting parts and the second limiting parts, double side locating and even multi-side locating of the anti-loosening gasket can be realized so that the structural stability of an anti-loosening structure is improved; and therefore, technical effects the product structure is optimized and the reliability and stability of the productare improved are achieved.

Description

technical field [0001] The invention relates to the technical field of railway turnouts, in particular to a bolt anti-loosening component and a turnout. Background technique [0002] Specifically, the working environment of fastening bolts on railway turnouts is complex and harsh, and the bolts are prone to loosening during long-term work, which brings many potential safety hazards and affects the safe running of trains. [0003] To solve this problem, two types of anti-rotation plate structures are generally used to prevent the high-strength bolts of turnouts from loosening. One is for two or three adjacent bolts, the anti-rotation sheet assembly is provided with an anti-rotation sheet shared by multiple bolts, and multiple adjacent bolts are connected to the anti-rotation sheet, but this structure is only applicable It is not suitable for single-hole bolts when multiple bolts are arranged in close distance. The other is to set a corresponding anti-rotation plate structur...
