Ratchet type anti-loose and anti-theft sleeper bolt assembly
The invention provides a ratchet type anti-loose and anti-theft sleeper bolt assembly, belongs to the technical field of railway track fastening, and solves the problem that a railway track becomes loose due to shock and reduces theft. The ratchet type anti-loose and anti-theft sleeper bolt assembly is composed of an anti-rotation sleeper bolt, an anti-rotation and anti-loose ratchet lock washer and a ratchet flange nut. When the anti-rotation sleeper bolt is sleeved by a fastening piece, an elastic strip and the anti-rotation and anti-loose ratchet lock washer and is screwed with the ratchet flange nut, the concave part on the anti-rotation sleeper bolt is just meshed with the convex part of an inner circle of the anti-rotation and anti-loose ratchet lock washer. The anti-rotation ratchet lock washer cannot rotate on the anti-rotation sleeper bolt; meanwhile a slant ratchet of the end surface of the anti-rotation and anti-loose ratchet lock washer is just meshed with a slant ratchet of the flange surface of the ratchet flange nut. The ratchet flange nut can only rotate in one direction and cannot rotate reversely, so as to achieve anti-loose and anti-theft purposes.
