Rail joint also called  rail fish plate  or joint bar is one of several railway components. Let's take a look at the fish plate sorted according to the position of the joints! There are also two types in this category. The first is a square connector and the second is a staggered connector. Square connector The rail joint on one rail is the opposite of the joint on the other side, called a square joint. This joint is suitable for linear rails, and the rail lines can be laid mechanically by section. When the train passes, the opposite joints are simultaneously subjected to impact. It reduces the number of impacts on the rails. The train will run more smoothly. Currently, such joints are commonly used on railway lines. Interlaced joint In this case, the distance between the two opposing joints is staggered by half a track. It is mainly applied to curved tracks, which distracts the impact of wheel rolling, but is not conducive to stability. We are  Rail Accessor...

Railway Accessories  are part of the railway line. The tracks referred to here include rails, sleepers, connecting parts, track beds, anti-climbing equipment, rail supports, and ballasts. As a holistic engineering structure, Hebei Yongyang Steel Sales Co., Ltd., the track is laid on the roadbed, plays a guiding role in train operation, and directly bears the tremendous pressure of the rolling stock and its load. Under the power of train operation, its various components must have sufficient strength and stability to ensure that the train runs safely, smoothly and without interruption according to the specified maximum speed. As a  Steel Rail Manufacturer  exporting  Tunnel Heavy Steel Rail  all over the world, we are one of the responsible people for ensuring the safe operation of the rails.

In order to ensure the normal operation of the railway, many parts are needed. These parts play an important role. The  rail fish plate  is a kind of connecting fastener used for the connection between the track and the track. It is an important part of the track. How should we maintain the fish plate? First, we must use the  fish bolt  produced by the supporting manufacturers to improve the performance. Secondly, when assembling the fishtail plate connecting rod cover, force the wrench to tighten and tighten according to the specified standard. There is also a secondary maintenance for every 12000km of operation. The engine oil sump should be removed when servicing the fishplate bolts. Check the engine bushing usage. If the clearance is too large, replace it immediately. Replace it at the same time. The connecting rod of the fishplate bolt should be replaced. If you find that the operation is not stable and there is abnormal noise during normal operation, you s...

Generally speaking, the heavier the  GB standard steel rail , the lesser the degree of rail damage will be, and it is not easy to bend and deform. According to this problem, the following two ways of strengthening. 1.  Heavy steel rail  alloying, which has simple production process, low investment, low energy consumption, overall reinforcement of the rail, the uniform hardness of the surface layer and good weldability. 2. Heat treatment of carbon steel, this method can also improve the strength and hardness of the rail, while good toughness, save the alloy, suitable for mass production. The practice of metallurgical industry believes that if the steel is not changed, it is difficult to increase the strength by carbon steel alone. Only the combination of micro-alloy and heat treatment can complement each other to obtain higher strength. High-quality rails with corresponding toughness, hardness and weldability.

Rail splint/connecting plate, commonly known as fishtail plate, it plays a connecting role at the rail joint. Rail splint is a kind of fastener used to connect rail to rail. Generally, it consists of the splint and matching fishtail bolts. It plays the role of connecting rails, facilitating the subsequent removal and reuse, and also has the use of direct welding without connecting plates. The  rail fish plate  is also commonly referred to as a splint. The fish plate is a connecting fastener used for the connection between the track and the track. It is divided into light rail, heavy rail and lifting rail. A screw hole is arranged in the middle of the screw hole, and an upper working face contacting the lower part of the rail head and a lower working face contacting the upper part of the rail bottom are arranged on the upper and lower sides of the horizontal axis of the screw hole. The rear part of the upper working face extends upward to form a transition section higher t...

Rails are usually divided into  light steel rail  and heavy steel rail. Low magnification defects of rails usually refer to metallurgical defects exposed in the whole section of rail specimens after acid corrosion through naked eyes (or low magnifying glass). 1. Hydrogen cracking. Hydrogen cracking refers to the appearance of a rail that appears in its section (usually on the head) after acid corrosion. This kind of spot is mostly white in its longitudinal section, so it is also called "white point". The white point is due to poor degassing during smelting or casting, and as the temperature decreases, the solubility of hydrogen in the steel becomes smaller and then precipitates into tiny pores. 2. Shrinkage holes. Shrinkage is a visible crack in the center of the waist or scattered in the waist after acid corrosion. It is caused by the insufficient length of the cutting head after the rail rolling, and it remains on the rail. When the smelting is not normal, the...

The rails are laid on top of the gravel, why lay it on the gravel instead of laying it directly on the ground. Today, the  China fish bolt wholesale  answers the question why the rails should be laid on the gravel. Let's take a look: 1. The load of the rolling stock is passed through the rails, and the sleepers are scattered on the roadbed surface through the diffusion of the track bed, which plays the role of protecting the roadbed. 2. Provides the longitudinal and lateral resistance against the rails and maintains the correct geometry of the track, which is especially important for seamless lines. 3. It is used for rainwater. When the train passes by, it will reduce the vibration and reduce the effect of floating dust. 4. Provide a certain elasticity and damping, play a role in cushioning and shock absorption. 5. The irregular arrangement of gravel can decompose the pressure of the track in different directions. The track is more stable and does not deform. 6. G...
