Description

Technical Field

[0001] The utility model relates to the technical field of railway buckle accessories, in particular to highly corrosion-resistant railway buckle accessories. Background Art

[0002] Railway fasteners are components used to fix rails to sleepers. They are crucial to ensuring the stability and safety of railway tracks. With the rapid development of the railway transportation industry, the requirements for the stability and durability of railway tracks are becoming increasingly higher. Railway fasteners are key components connecting rails and sleepers, and their quality and performance directly affect the safe operation of railways.

[0003] The Chinese patent with the announcement number CN204608516U discloses a type II railway buckle accessory, comprising a pad placed on a base, a convex edge is provided on the upper end surface of the rear end of the pad, a rubber pad placed under the rail, a type II spring bar installed above the pad and a fixing bolt, and an extension is provided on both sides of the lower end surface of the rubber pad obliquely downward, and the extension clamps the edge of the base; a vertical stopper is provided at the front end of the pad, a pressure block is provided at the lower end of the front end of the vertical stopper, and a notch for accommodating the stopper is also provided at the front and rear ends of the rubber pad, and grooves for accommodating the pressure block are provided on the lower end surfaces of both sides of the rubber pad. A stopper is provided to effectively prevent the track from swinging out of the fixed position of the pad after being subjected to horizontal force; the setting of the pressure block makes the pad and the track more tightly connected, and no relative displacement occurs arbitrarily; the recessed design on the lower end surface of the pad effectively prevents the defect that the bolt and the pad are difficult to loosen due to long-term connection corrosion. However, the above patent is prone to corrosion in harsh environments during use. When the corrosion is severe, the screws are prone to loosening and the fixation is not firm, which affects the stability of the track and the safe operation of the train, thereby reducing the service life and reliability of the buckle accessories. To this end, we propose highly corrosion-resistant railway buckle accessories to solve the above problems. Utility Model Content
