The railway fastener manufacturers tell you that the elastic fasteners can be divided into different models, which can meet the operating conditions of passenger routes. V-type elastic fastener is mainly designed for the line conditions of laying prestressed concrete ballast track with shoulder bolster. The railway fastener manufacturer tells you that the V-type elastic fastener is improved on the basis of the original elastic I, II type fasteners and I elastic type height-adjusting fasteners, under the condition that the size and position of the existing sleeper bearing grooves remain unchanged. made of.

The railway fastener manufacturer tells you that the V-type elastic clip is composed of elastic strips, screw spikes, flat washers, gauge baffles, under-rail pads and embedded casings positioned in prestressed concrete with shoulder pillows. The height-adjusting backing plate is used to adjust the height of the rail. The V-type elastic strip fastener is an elastic non-separable fastener with a concrete shoulder for the sleeper. The elastic strip is fastened by the screw spike and the casing, which improves the insulation of the fastener system. Performance, can be installed with a variety of elastic strips, both large buckle pressure spring strips and small buckle pressure spring strips can be installed, with different friction coefficients of under-rail pads (rubber pads or composite pads) to meet the requirements of different line resistances. Require. The railway fastener manufacturer tells you to use the gauge baffles made of engineering plastics to adjust the gauge and insulate, reduce the number of fastener components, and avoid affecting the stress state of the screw spikes when adjusting the gauge; The height adjustment pad is placed between the sleeper bearing surfaces to realize the height adjustment of the rail.
The railway fastener manufacturer tells you that in terms of overall structure, the V-type elastic clip is optimized and improved in several aspects on the basis of the original fastener structure, such as improving the insulation performance of the fastener system; improving the fatigue performance of the elastic strip ; At the same time, it is considered that a small buckle pressure elastic strip and a composite backing plate with a small friction coefficient can be installed, which has the function of a small resistance fastener.
