Rail clip installation rail clip installation Prerequisites for the rail clip installation 1. The rail presser is installed after the steel beam on the crane rails surface is adjusted; 2. The steel beam of the crane must be 3. The rail pressure device should be installed; 4. Before the installation of the  rail clamp , the surface paint of the crane beam is finished and meets the requirements of the current regulations; 5. Before the installation of the rail presser, the track joints should be connected, and the track joints and side bending deviations should meet the requirements of “Steel Structure Engineering and Acceptance Specifications”-83). 6. The welding of the base plate control plate and the steel suspension beam should meet the design requirements. Installation sequence and essentials A. Welding the fixed base, the fixed base can be used, the three grooves on the surface and the position of the rail presser can be positioned, and the allowable deviation of the position ...

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 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...

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...

  How to install fish plate in railway Rail joint , also known as the fish plate in railway, is a common accessory on railway tracks . As a major railway country, China uses different types of rails and different models. Therefore, for the fixed parts such as road splints, the specifications are also different. Fishplate is a common fastener on rails. In addition to testing the quality of the fishplate, it should also be installed to prevent improper installation and affect its normal use. Let’s follow the splint manufacturer to see how to install the fish plate on the railway. fish plate in railway 1. When screwing on the bolt, pay attention to make the opening of the spring washer downward; 2. The order of the bolts, such as using a four-hole fish plate, first tighten the middle two, then the two sides, after tightening the two sides, and then tighten the middle once; 3. When screwing the bolts, one person shall use a 55cm screw wrench as the criterion, and a too long screw wrenc...

  What are seamless rails? seamless rails Continuous seamless rails, also known as a welded long rail line, is a line that welds ordinary rails without leaving rail seams. meters or longer. The long rails are laid and fixed on the sleepers within the specified temperature range. There are rail slits at the end of the long rail, and the middle part cannot expand or contract with the temperature rise and fall. Therefore, the middle section of the steel rail will generate a large temperature pressure in summer and a large temperature tension in winter. The large pressure and tensile force in the rail can be calculated according to the annual high and low temperature of the place where the rail is laid. The large pressure on the rail should not cause the rail to buckle, and the large tensile force should not cause the rail to break. The seamless rails line greatly reduces the  rail joints , reduces the impact on the rails when the wheels pass through the joints, is conducive to s...
