2、 Material requirements
The pressure plate and base plate of the car stop and fixed track shall be made of Q235-B steel, and its material shall comply with the provisions of Carbon Structural Steel GB/T700-1988. The performance level of bolts is 4.8. The plywood of Expansion joint shall be Q345-B steel, and its material shall comply with the provisions of Low Alloy High Strength Structural Steel (GB/T1591-1994). Grade C hexagonal head bolts, nuts, spring washers, and flat washers shall comply with the provisions of national standards GB/T5780-2000, GB/T41-2000, GB, T93-1987, and GB/T-2002 respectively
3、 Installation requirements
When using a pressure plate to fix the track, the base plate should be in close contact with the track. The connection weld between the pressure plate and the base plate must be welded after the track is adjusted. Before welding, tighten the bolts and press the track tightly. After welding, check one by one and ensure that the track is not loose.
According to the regulations of crane track connection and national vehicle stop (designed according to national building standards):
1. The Centre-to-centre distance between the two holes of all pressing plates is 800mm.
2. A value: 90mm for 38kg/m rail, 90mm for 438kg/m rail, 100mm for QU80 rail, 105mm for QU100 rail, and 115mm for QU120 rail.
The track pressure plate, as an important component of the railway track, plays a crucial role in application. It can be adjusted laterally during and after installation, and the pressure plate has different adjustment ranges according to different types. Equipped with double-sided wedge connection for active locking function.
The track pressure plate can accept different lateral forces according to different types. The vulcanized rubber nose on the track pressure plate clamp has compensation for the manufacturing tolerance of steel rails and steel beams; Eliminate fatigue stress on bolts; Avoid loosening bolts; Move in the direction of the axis of the steel rail; Pre tightening rail bottom rubber pad and other functions. After vulcanization treatment, ensure that the rubber nose is accustomed to various working conditions, reduce noise and vibration. In addition, the track pressure plate should also be protected against rust in daily repair and maintenance. If the track pressure plate rusts, it can affect the normal operation of the train on the track. If you are not careful, it can lead to major railway accidents.
