Railway fishplates are also called rail joints or joint bars. As one of the rail components, the function of the rail joint is different from other rail components.
The rail joint is a flat metal plate, usually used to connect two adjacent rails through several rail bolts or rail spikes. Traditionally, railway fishplates have holes drilled at the ends of the parts to be connected. There are some holes at the end of the railway track, which are used to align with the holes on the railway fishplate and are connected with rail bolts.
Generally speaking, railway fishplates are made of steel, but plastics and composite materials are alternative raw materials for rail joints.
Application of railway fishplate:
Railway fishplates are widely used in heavy rail, light rail and crane rails, and railway fishplates are different for different standard rails. More than 30 kinds of railway fishplates can be produced according to different standards:
Light rail fish plate: 8kg, 9kg, 12kg, 15kg, 18kg, 22kg, 24kg, 30kg
Railway fish plate for heavy rail: 38kg, 43kg, 50kg, 60kg
Railway fishplates for crane rails: QU70, QU80, QU100 and QU120
Types of railway fishplates:
According to different applications, rail joints can be divided into many types. Typical rail joint types include common rail joints, insulated rail joints, non-standard rail joints and compromised rail joints.
1. Common rail joint
Common rail fishplates are made of general material Q235 steel, which can be used for various types of rails. The appearance and weight of ordinary rail joints vary with the weight of railway tracks. The main types of ordinary railway fishplates are 4 holes and 6 holes.
2. Insulated rail joint
The raw materials and production process of insulated rail joints are determined by the process standards of the insulation materials. The size of the insulated rail joint is the same as the common rail joint. Insulated rail joints are generally used in railway sections or leaky sections near power plants. Insulated rail joints can effectively prevent leakage accidents.
3. Non-standard rail joint
There are many types of non-standard rail joints in all rail joints. The section and speed of different railways determine the difference between some rail joints and ordinary railway fishplates. Generally, there are three types of non-standard rail joints with different weights, different pitches and different appearances.
4. Compromise rail joints
Compromise rail joints are different from non-standard rail joints. Generally compromised rail joints include protruding railway fishplates and railway turnout expansion joints. Eclectic rail joints are basically customized, mainly used for turnout expansion joints or the appearance of some railway sections with special designs and requirements. Compared with other types of rail joints, compromised rail joints are difficult to machine.
