As a kind of railway parts, rail clamps are a reliable connection between the crane track and the ground (or load-bearing beam). It is arranged along the entire length of the guide rail. One set is set every 500mm, and one set is two pairs. In the operating state of the crane, it can withstand vertical and lateral impact forces, and can withstand the additional lateral force generated by the crane's deflection operation. Rail clamps adopt adjustable combined pressure plate to overcome the failures in the use of traditional rail clamps.
After the rail clamps are installed, the reliable contact between the rail clamps and the crane rail cannot be protected. Some railway clamps cannot adjust the horizontal direction after installation, so they may be caused by normal loading or thermal expansion and cold contraction. The longitudinal movement of the lifting crane rail is easy to wear, which causes the bolts of the railway clamp to loosen. Loose, the pressure plate rotates, the track surface is worn and bites the crane track, and in severe cases, the crane track will be broken, which will affect the wear of the main wheel and the damage of the driving mechanism.
When using adjustable rail clamps, the rail can be fixed horizontally, or the position of the crane rail can be adjusted horizontally. In addition, rail clamps have a self-locking function, which can reliably fix the crane track and prevent the crane track from shifting under heavy wheel pressure. The crane rail is fixed in the vertical direction by elastic force. When the crane track undergoes thermal expansion and contraction, the crane track can also be allowed to move longitudinally without wearing the rail clamps, and the bottom surface of the track is in close contact with the rubber composite pad laid on the track.
In order to ensure the smooth and stable operation of the crane, it is often used to lay welding rails. Each section of the entire crane track is welded into one. There are no joints in the weld. In the middle, but this type of installation is very demanding and has a lot of thermal expansion and cold contraction. Adjustable combined rail clamps are especially suitable for this kind of crane rail belt fixation, which can well eliminate the disadvantages caused by the use of welding rails.
