Introduction of rail clamp

rail clamp

A rail clamp is a component used to fix rails and is usually used in fields such as railways, urban rail transit, and port lifting equipment. Its function is to tightly connect the rail with the track base to ensure the stability and safety of the rail track.

Rail clamps are usually made of steel or other metals with great compressive and tensile strength. The design of the rail clamp can be optimized according to different application scenarios and needs, for example, it can be selected according to the model of the track, the radius of the curve, the axle load, and other parameters.

Common types of rail clamps include clip-type rail clamps, elastic clamp-type rail clamps, steel bar clamp-type rail clamps, rubber gasket-type rail clamps, etc. Different types of rail clamps are suitable for different track types and environmental conditions and need to be selected according to specific conditions.

The installation and maintenance of rail clamps are also very important. When installing, it is necessary to ensure the size and position accuracy of the track and track base to guarantee the tight connection and fixation of the rail clamp. During daily use, the rail clamp needs to be checked and maintained regularly to sustain its stability and safety.

Specifically, rail clamps can be divided into WJK, SWJK, HWJK series as well as TG38, TG43, TG50, TG60, QU70, QU80, QU100, and QU120 types, depending on the base, upper cover, piercing, and elastic flat washers.

Rail clamp material

1: Semi-cast steel: the upper cover is ductile iron, and the base is cast steel.
2: All cast steel: the upper cover and base are all cast steel.

This time we only introduce the full-cast steel rail press:

(1) The material of the upper cover, base, and adjustment plate is ZG270-500. It should meet the requirements of 5676-85. Use lost wax fine casting. Class II quantity and dimensional deviation meet JZ67-2 Class II accuracy requirements.
(2) Bolts and nuts are Q235BF steel processing parts, mechanical properties, and chemical composition are specified in GB700-88, bolt surface accuracy is 12.5, and nuts meet the requirements of GB 6170-86.
(3) Flat washers 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.

The above product dimensions are in accordance with the atlas 04G325 or 05G525
