Product Introduction
Railway Equipment is an important part of railway tracks. It is mainly used to connect rails and sleepers, and evenly transfer the vertical force, lateral force and longitudinal force transmitted by the train through the rails to the sleepers and the lower infrastructure to ensure the stability and bearing capacity of the track structure.
Diamond head bolt with nut:
Specifications: Generally there are a variety of sizes, common thread diameters are M16, M20, etc., and the size is usually 20x132MM, etc.
Application scenarios: Used in the connection of special parts of railway equipment, such as the fixing of the housing of some railway signal equipment, etc., using the characteristics of its diamond head to facilitate operation and tightening in a specific space.
Square head bolt with nut:
Specifications: The commonly used square head bolts in railways are M22, M24, etc., and the length is usually 100mm - 300mm. For example, the square head bolts used at the rail joints may be about 150mm - 170mm in length.
Application scenarios: In railway tracks, square head bolts are often used to connect the rail joint splints, that is, used as fish bolts, which can withstand the huge tension and impact force generated by the train running, and ensure the stability of the rail joints. It is also used in the steel structure connection parts of some railway bridges, tunnels and other infrastructures. Because its square head is not easy to turn, it is convenient for construction workers to use wrenches and other tools for tightening operations.
Hex nut:
Specifications: It is compatible with commonly used railway bolts, and has specifications such as M16, M20, and M22. There are corresponding standard requirements for its opposite side size and thickness. For example, the opposite side size of the M20 hexagonal nut is about 30mm and the thickness is about 18mm.
Application scenarios: It is widely used in the connection parts of railway tracks, railway vehicles, and various railway equipment. On the track, it is used to fix sleeper fasteners, connect rail accessories, etc.; on railway vehicles, it is used to connect various parts of the vehicle, such as bogies, body structures, etc.; in other railway facilities such as railway signal equipment and power supply equipment, it is also used for the fastening and connection of various parts.
Washers:
Specifications: Flat washers have various specifications, such as inner diameters of 16mm, 18mm, 20mm, etc., corresponding to different bolt diameters. The specifications of spring washers also match the bolts, and common models are suitable for M6-M24 bolts.
Application scenarios: Flat washers are mainly used to protect the surface of the connected parts to prevent the surface from being scratched when the nuts are tightened, while increasing the contact area and dispersing the pressure. Spring washers are used to prevent nuts from loosening. In railway equipment, whether it is track connection parts or connection parts of vehicles, signal equipment, etc., as long as bolts and nuts are used for connection, corresponding washers are usually equipped to improve the reliability and stability of the connection.
Spike:
Specifications: The specifications of railway spikes are generally 100mm * 100mm * 20mm, the maximum height does not exceed 25mm, and the diameter of the spike rod is usually around 16mm - 22mm.
Application scenarios: Mainly used to fix the rails on the sleepers, divided into ordinary spikes and spiral spikes. Ordinary spikes are nailed into the sleepers by hammering, while spiral spikes need to be screwed into the sleepers using special tools. They can provide reliable anchoring force to ensure that the rails maintain the correct position and direction under the load of the train.
