Gantry rail fixing clips installation
Gantry rail fixing clips adopt an adjustable combined rail pressing plate, which can overcome the failures of the traditional rail pressing plate in use. The traditional rail clip is often directly pressed with the rail steel to the steel rail in use. Some gantry rail fixing clips can no longer be adjusted in the horizontal direction after installation, so after normal loading or thermal expansion and contraction caused by longitudinal movement of the track, it is easy to wear, causing the bolts of the pressure plate to loosen and the pressure plate to rotate, causing the surface of the track to wear and gnaw. If the rail is broken, the rail will be broken in severe cases, which will also affect the wear of the main engine wheels and damage the drive mechanism. When using the adjustable combined track platen, the track can be fixed in the horizontal direction, and the position of the track can be adjusted horizontally. For example, the QU80 platen allows the lateral adjustment of the track to a distance of 15mm. For example, the QU120 gantry rail fixing clips allow the lateral adjustment of the track to a distance of 20mm. And it has a self-locking function, which can reliably fix the track and prevent the track from shifting when it is pressed by a large wheel. Use elastic force to fix the track in the vertical direction. That is, the hot glue rubber tongue is pressed on the track indenter, and the tongue is made of synthetic rubber that is wear-resistant, oil-resistant, high-temperature resistant, and corrosion-resistant.
Installation sequence and essentials
A. Welding the fixed base, the fixed base can be used, the three grooves on the surface and the precise position of the rail presser can be positioned, and the allowable deviation of the position to the precise line of the crane beam is ±1.0mm;
B. Put in the T-bolts and push them into place in the direction of the rail;
C. Put in the wedge-shaped adjustment plate, and make the grooved side face up;
D. Install the rail pressure plate, washer, spring washer and nut in sequence;
E. Move the wedge-shaped adjustment plate, adjust the position of the rail presser perpendicular to the direction of the rail, and tighten the nut after the rail pressing plate and the lower flange of the rail are tightly pressed;
F. The influence on the disturbance of the crane beam when the fixed plate is welded should be considered in the design or construction.
