What are the commonly used rail buckle plate fasteners?
Rail rigid fasteners refer to the fastening device parts of rails and sleepers with rigid fastening parts. Rail rigid fasteners (rigid rail fastening) refer to the fastening device parts of rails and sleepers with rigid fastening parts. K-type fasteners used for bridge seamless lines also belong to this type. We can produce railway gusset plates with complete specifications for you to meet the use of different rail models, whether it is subways, ordinary lines and crane tracks, etc. The raw material usually uses Q235, and the production process is forging, or ZG35 and QT500-7 are used for casting.
The gusset plate fastener system is a type of track fastener system. It is a rigid fastener. At present, the KPO series is mainly used abroad. The following types of track gusset plate fasteners are widely used:
The fasteners used in concrete sleepers are all non-separable. Except for the bolt fasteners, type 63 and type 70 fasteners developed earlier, which are rigid fasteners, the others are elastic fasteners. Due to the limited production level of the 63 type gusset plate fastener at that time, there was no sulfur anchoring technology. The only way was to embed wooden bolts in the concrete sleeper and screw in the bolt spikes to connect the fastener and the sleeper. This type has become history. Now It's hard to see anymore. The 70-type gusset plate fastener is a shoulder type and is suitable for 50 and 43kg/m rails. The gusset plate is used to fasten the rail and the track gauge can be adjusted by replacing the gusset plates with different numbers. The connection between the spiral spike and the sleeper adopts the sulfur anchoring form. The wooden pegs were removed. At present, new railways are rarely laid and are only used for maintenance of existing lines. Bolt buckle plate fasteners, type 63 buckle plate fasteners, and type 70 buckle plate fasteners all use rigid buckle plates. The concrete sleepers are equipped with shoulders, and the bolts used to fasten the buckle plates or are fixed in the reserved holes of the concrete sleepers. into the pallet, or spirally screwed from the lower part into the wooden casing embedded in the sleeper, or use sulfur anchoring to anchor into the reserved hole of the concrete sleeper.
