Generally, there are two types of rail beams for installing rail fasteners, one is concrete material and the other is steel structure material. For concrete beams, pre-embedded holes must be reserved in advance when building beams. These holes are used for bolts when installing rail fasteners. Of course, bolts can also be directly buried in beams.

Commonly used installation methods include hook screw fixation, pressure plate fixation, welding, and bolt combination fixation. When punching, the depth of the hole must be deep enough. This is to facilitate the later adjustment in the horizontal direction. If you need to adjust in the vertical direction, remember to put a cushion under the rail.

The material of the rail fasteners is different and the rigidity is also different. It can be set to single-hole or double-hole according to the force situation on site. There are also many connection methods to choose from. It should be noted that only when the steel backing plate and the rail are welded At the same time, the rail fixing parts can be installed in the same welding method, so there are certain limitations. However, the firmness of the welding is the best. As long as the anti-rust measures are in place at ordinary times, the welding can be used for a long time without loosening or falling off.

There are also certain requirements for the rail beams when installing the rail fasteners. The distance between the horizontal and vertical reserved bolt holes needs to be more than 5 mm, which is convenient for the later fasteners; the diameter of the screw holes should also be larger than the actual diameter of the bolts. Larger, generally 3 mm is enough, otherwise, it may be blocked and other reasons that cannot be installed.

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
