Product features of rail press

Welded rail clamp is one of many rail clamps, which is a welded rail fixture. Its function is to compress and fix the rail, which is usually welded on I-beams, and sometimes on embedded concrete slabs. Each set of rail pressing device includes base, upper cover, through pin, screw and elastic bottom plate.

In order to ensure the quality of the rail presser, there are strict requirements for materials in the manufacturing and processing process, and its technical conditions meet the standards. The pressing plate is made of carbon steel castings or segmented cast steel, and its mechanical properties meet the requirements of rail presses. The elastic plate is made of composite rubber plate, and the rubber plate is made of oil-resistant rubber, and its performance meets the standard of composite vulcanized rubber plate.

Rail press

In order to achieve the desired effect, in addition to ensuring the quality of the rail press, it is also necessary to master the correct installation method and comply with its installation requirements.

Everyone may not be familiar with the crane. The crane is similar to what we call the crane, which is widely used in the storage industry. In order to make the running of the train more efficient, the track press plays an important role on the train track. Due to the long working hours and frequent starting and stopping of daily work, it is difficult to adjust the hydraulic brake to a synchronous state, which is likely to cause parking deflection and generate large torque. Under direct long-term action, the bolts are easily loosened or even damaged. . The rail press can make up for this deficiency, and the T-bolt is used to cover the base groove to buffer torque and ensure the normal tightening of the rail press. The rail presser plays a very important role on the running track, but at the same time it also improves the service life of the train, which is of great significance. Rail presses are sometimes used on train tracks. The use of rail presses greatly guarantees the safe running of trains and greatly improves the stability of train tracks.

There are two types of rail presses, ductile iron and cast steel.

The standard of the cast steel rail presser: (1) The material of the upper cover, base and adjustment plate is ZG270-500. It should comply with the regulations of 5676-85. It adopts lost wax precision casting. Grade II, dimensional deviation conforms to JZ67-2II Accuracy requirements..

(2) The bolts and nuts are Q235BF steel processing parts, the mechanical properties and chemical composition are in accordance with the provisions of GB700-88, the surface accuracy of the bolts is 12.5, and the nuts are in accordance with the provisions of GB 6170-86.

(3) The material of the flat washer is Q235AF steel, which should meet the requirements of GB97.1-85

(4) The spring washer is made of 65Mn or 60si2Mn steel, which should meet the requirements of GB93-87.
