After installing the railway track clamps, reliable contact between the rail clamps and the guide rail cannot be guaranteed. Some rail clamps cannot be adjusted horizontally after installation, so they may be caused by normal loading or thermal expansion and cold contraction. The lifting rail is easy to wear after the longitudinal movement, which causes the bolts of the pressing plate to loosen. Loose, the pressure plate rotates, the track surface wears and bites the track, and the track will be broken in severe cases, which will also affect the wear of the main wheel and the damage of the drive mechanism. When using the adjustable combined railway track clamps, the track can be fixed horizontally or the position of the track can be adjusted horizontally. In addition, railway track clamps have a self-locking function, which can reliably fix the track and prevent the track from shifting under heavy wheel pressure. The track is fixed in the vertical direction by elastic force. In other words, the hot rubber tongue on the track head is made of abrasion-resistant, oil-resistant, high-temperature, and corrosion-resistant synthetic rubber.
When the track is subjected to thermal expansion and contraction, it can also allow the track to move longitudinally without wearing the railway track clamps, and make the bottom surface of the track in close contact with the rubber composite pad laid on the track. In order to ensure the smooth and stable operation of the crane, nowadays, it is often used to lay welded tracks, that is, each section of the entire crane track is welded into one, and 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 railway track clamps are especially suitable for this kind of track belt fixing, which can well eliminate the disadvantages caused by the use of welded tracks.
