Crane rail installation

 


Crane rail installation

Crane rails include special rails, railway rails, square rails, and P-type rails; square rails have relatively large wear on the wheels and are rarely used; most cranes and trucks use P-type rails.

The crane rail installation methods include pressure plate fixation, hook screw fixation, welding and bolt combination fixation, etc. In order to adjust the horizontal direction, the holes on the rail pressure plate are usually made as long holes, and the vertical adjustment can be made by adding pads under the rail. When designing the rail pressure plate, it should have sufficient rigidity. Each pressure plate can be made into a single hole or double hole according to the size of the force. Only when the rail and the rail beam or the steel backing plate fixed on the rail beam are connected by welding, the rail can be welded on the rail.

Rail clamps and rail pads are also an important part of the crane rail system, which respectively play the role of fixing the rail and buffering the impact on the rail, and also prolonging the service life of the rail system.

Principle of rail clamp design

Principle of rail clamp design rail clamp design The rail clamp design has several functional features: 1. Adjustability: The adjustable length is 15mm, and its adjustability functions include: (1) The rail presser is easy to install, saves time, and has high precision (2) The track can be adjusted if the structure of the support beam is slightly changed. 2. Anti-loosening: Under the action of the lateral force of the track, through the force analysis of the welding RTYB, a part of these lateral forces are transmitted to the bottom seat through the upper cover plate as the pressure of the bottom edge to seat on the upper cover plate. The other part is the lateral friction between the base and the upper cover. Since the wedge-shaped action between the base and the upper cover plate is converted into the tightening force of the bolts, it has an anti-loosening effect. 3. Self-locking: The three pieces are self-locking together through the interaction of the upper cover, the base, and the

What is rail creep

What is rail creep rail creep Rail creep is also known as line crawl. The creeping phenomenon of the rail along the longitudinal direction of the line. With the increase in railway transportation tasks, the impact of the wheels on the rails when the train is running accelerates the creep of the rails. Rail creep can cause many diseases of the line. In order to prevent the occurrence of track creep diseases, it is necessary to find out the real cause of creeping in order to effectively eliminate the problem. There are two different manifestations: the rails move along the soft sleeper surface due to insufficient fastening pressure of the fasteners; the longitudinal movement of the row is caused by insufficient ballast bed resistance. The reason for this is the longitudinal force of the rail caused by the wheel rolling and longitudinal slip, train braking, the change of rail temperature, and the creep caused by the deflection and deformation of the rail under the action of the wheel load
