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 fastening bolts. At the same time, the rail presser is placed symmetrically with the crane rails. One side of the rail presser prevents the rail from moving in the left direction of the longitudinal force, and the other side rail presser prevents the rail from running in the right direction of the longitudinal force, so that the rail, the rail presser, and the support beam are self-locking into one.

4. Positive moment: Since the force point is behind the tightening bolt, the tightening load of the bolt will always generate a positive moment on the track.

Features of rail clamps

The purpose of the rail press is to compress and fix the rail, making the vehicle run more efficiently. Due to the long-running time of some rails and frequent start and stop, parking deflection often occurs, resulting in large torque. Over time, the bolts are easily loosened or even damaged. The rail press can make up for this defect, it plays a very important role in the running track and is of great significance.

In order to ensure the quality of the rail presser, the rail presser has strict requirements on materials in the manufacturing process, and its technical conditions meet the standards. The pressing plate is made of carbon steel castings or segmented cast steel, and its mechanical properties meet the requirements of orbital presses. The elastic plate adopts a composite rubber plate, and the rubber plate adopts oil-resistant rubber, and its performance meets the standard of a composite vulcanized rubber plate.

In order to achieve the desired effect, in addition to ensuring the quality of the rail press, it is also necessary to master the correct installation method and comply with its installation requirements. Also, there are two types of orbital presses, ductile iron, and cast steel. Today, the main explanation is the cast rail press.

Welding Process of Overhead Crane Rail Joint

Welding Process of Overhead Crane Rail Joint In order to make the overhead crane rail transport more stable, rail splints will not be used for the overhead crane rail joint connection, but welded joint connection will be used. The main key to the welded joint is to solve the bending deformation and weld cracking of the overhead crane rail joint. During the welding process of the overhead crane rail joint, the overhead crane rail joint is deformed downwardly, so the overhead crane rail end must be padded to a certain height before welding to ensure that the rail joint can be kept straight after the welding is completed. The height of the rail end pad is determined by factors such as the type of rail, length, fixing method and ambient temperature. The rails are fixed to the crane beam by means of hook bolts, and each joint is provided with four fixed points. After the bottom of the rail is welded, reduce the height to 20mm, and then tighten the hook bolts to continue welding. When the o...

What are railway rail fasteners？

What are railway rail fasteners？ Railway rail fasteners Railway rail fasteners are a kind of railway accessories. The parts used to combine rails and sleepers (or other types of under-rail foundations) on the track are also called central joint parts. Its function is to fix the steel rail on the sleeper, maintain the gauge and prevent the longitudinal and lateral movement of the rail relative to the sleeper. The railway rail fastener system is divided into the shrapnel fastener system, gusset fastener system, and elastic strip fastener system. The gusset-type fastener is composed of a gusset plate, a threaded spike, a spring washer, an iron seat, and a buffer pad. The threaded spike is anchored in the reserved hole of the concrete sleeper bearing platform with sulfur cement mortar, and then bolts are used to fasten the buckle. Plate fastened. There are elastic strips I, II, and III types of clip fasteners. Type I elastic strip is composed of ω elastic strip,  screw spike , gauge b...
