1.simple structure, is stronger and more durable, and is suitable for popularization and use.
Kingrail develop An anti-loosening track bolt relates to the technical field of TBM engineering, and includes a bolt and a nut that cooperate with each other. The rod part of the nut is provided with an external thread, the internal thread is matched with the external thread, and an integrally formed insertion rod is also provided in the middle of the inner surface of the closed end of the nut along the axial direction, and the end of the rod part is also axially formed. A groove is provided, and a limiting mechanism is arranged between the insertion rod and the groove. When the nut is screwed on the rod, the rotation of the nut is limited by the limiting mechanism. The invention can effectively overcome the loosening of the track bolts due to the vibration of the battery car wheel, so that the track bolts can be kept firmly locked for a long time.
2. Forging production, longer lifespan
3.100% quality inspection before delivery
Kingrail adopts a rail bolt anti-rust grease composition and a preparation process, and belongs to the technical field of petrochemical industry and organic synthesis. It is made from the following raw materials by mass: 50-60 parts of base oil, 35-45 parts of thickener, 3-10 parts of rust inhibitor, and 0.5-1 part of antioxidant; the base oil is selected from low freezing point intermediate base mineral oil; The thickening agent is selected from higher fatty acid lithium-calcium composite soap; the rust inhibitor is selected from the combination of barium petroleum sulfonate and barium dinonylnaphthalene sulfonate; the antioxidant is selected from diphenylamine. The invention has better anti-rust performance for rail bolts in humid environment and conditions containing acid, alkali and salt, is suitable for the ambient temperature of 50-100 ℃ in the south and north of my country, and is used under all weather conditions without loss or curing. No cracking, can maintain a good oil film state. At the same time, it does not pollute the environment and does not harm the health of workers.
Kingrail strength roducts:
Raiwlay track materials: fishplates, steel rail, rail clamps, tie plates, fishplates, track bolts with nuts and washers, gauge rod, etc
Railway vehicle spares: wheels, axles, tyres, bearings, etc
