Introduction of rail clamp

 


Introduction of rail clamp

Rail clamp: also known as welded rail clamp, welded rail fixing device, steel beam rail clamp, welded clamp, no matter what it is called, the only function is to press and fix the rail.
Rail presses can be divided into WJK, SWJK, HWJK series TG38, TG43, TG50, TG60, QU70, QU80, QU100, QU120 by the base, upper cover, piercing, and elastic flat washers.
Rail clamp material: There are two kinds of rail press materials:
1: Semi-cast steel: the upper cover is ductile iron, and the base is cast steel.
2: All cast steel: the upper cover and base are all cast steel.
This time we only introduce the full cast steel rail press: (1) The material of the upper cover, base, and adjustment plate is ZG270-500. It should meet the requirements of 5676-85. Use lost wax fine casting. Class II quantity, dimensional deviation meets JZ67-2 Class II accuracy requirements.
(2) Bolts and nuts are Q235BF steel processing parts, mechanical properties, and chemical composition are specified in GB700-88, bolt surface accuracy is 12.5, and nuts meet the requirements of GB 6170-86.
(3) Flat washers should meet the requirements of GB97.1-85
(4) The spring washer is made of 65Mn or 60si2Mn steel, which should meet the requirements of GB93-87.

The above product dimensions are in accordance with the atlas 04G325 or 05G525
Everyone knows that the rail clamp plate is an accessory used to press and fix the rail and the I-beam or concrete beam or the ground. Generally, it is fastened with hexagonal bolts or embedded bolts. The track pressure plate is also called (traffic track pressure plate, crane pressure plate, steel rail pressure plate, lifting rail pressure plate). The track pressure plate is composed of a base, a pressure head, a pressure tongue, a bolt (8.8S), a nut (8H), and a fastening nut. The track clamp is a reliable connection piece for the crane rail and the ground (or load-bearing beam). It is arranged along the entire length of the track. One set is set every 500mm, and the set is two sets. The symmetrical scenery is on both sides of the track and runs on the crane. In the state, it can follow the vertical and lateral impact force and can withstand the additional lateral force generated by the crane’s skewed operation. So, do you know how important the track pressure plate is?
The function of the rail clamp is to fix the track, but if the double-beam crane is in a working environment with high speed, frequent or large wheel pressure, the existing fixing method cannot meet its performance requirements. At this time, the track pressure plate nut loosens, the track pressure plate falls off, and the track pressure plate bolts break easily. When the pressure plate of the driving track becomes loose, it will inevitably cause track displacement, rail gnawing, and other failures. In severe cases, it may even cause the driving to derail. Therefore, the track pressure plate is very useful in many places.

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...
