Railroad fishtail plates, also known as rail joints or joint bars. As one of the rail components, the function of rail joint is different from other rail components. A rail joint is a flat metal plate that is usually used to connect two adjacent rails by a number of rail bolts or railroad spikes.
Traditionally, railroad fishtail plates have a number of holes drilled in the end of the section to be joined. The railroad track has holes at the end to align with the holes in the railroad fishtail plate and is connected with rail bolts. Generally, railway fishtail plates are made of steel, but plastic and composite materials are alternative raw materials for steel rail joints.
Depending on the application, rail joints can be divided into various types.
Common rail fishtail plate is made of general material Q235 steel, this kind of rail fishtail plate can be used for various types of tracks. The appearance and weight of common rail joints vary somewhat with the weight of the railroad track.
The raw material and production process of insulated rail joints are determined by the process standards of the insulating material. The dimensions of insulated rail joints are the same as those of ordinary rail joints. Insulated rail joints are generally used in railroad sections near power plants or leaky sections. Insulated rail joints can effectively prevent leakage accidents.
Non-standard rail joints have a wide variety among all rail joints. For different railroad sections and speeds, it determines the difference between certain rail joints and common railroad fishtail plates. Usually, there are three types of non-standard rail joints with different weight, different pitch and different appearance.
Compromise rail joints are different from non-standard rail joints. Generally compromise rail joints include projecting railroad fishtail plates and railroad turnout expansion joints. Compromise rail joints are mainly used in turnout expansion joints or some special design and requirements of the appearance of the railroad section. Compared with other types of rail joints, eclectic rail joints are difficult to process.
When the train is running at high speed, the vehicle will produce huge impact and friction. Railroad safety transportation needs high quality railroad fishtail plate, in addition, the maintenance of railroad fishtail plate is also important.
First, the use of supporting fishtail bolts can improve the performance of the railway fishtail plate.
Secondly, you can tighten the connecting rod cover hard with a wrench.
Also, secondary maintenance is carried out every 1200km of operation. When maintaining the railway fishtail plate, you should remove the engine oil sump, check the use of engine bearings, and the gap should be replaced immediately if it is too large.
Finally, in the daily operation, should pay attention to the running instability or abnormal noise, and timely inspection.
