Spring Fastener Assembly And Gauge Adjustment Configuration

Type II clips look the same as Type I clips, and they also have gauge backing plates, but Type II clips have the advantages of high fastening strength, large buckle pressure, large strength safety reserve, and small residual deformation. It is suitable for straight lines and curves of standard gauge railways, and the radius is not less than 300m to connect 60kg/m steel rails and prestressed concrete sleepers, prestressed concrete wide sleepers, and the height adjustment is 10mm.
For anchoring screw spikes, the distance between the bottom surface of the spike boss and the bearing groove surface of the sleeper shall not exceed 2mm. The anchoring position of the spike should be based on the distance between the bottom surface of the boss and the groove surface of the rail should not be greater than 2mm, to ensure that the boss does not touch the bottom surface of the gauge baffle, the skew angle of the spike should not exceed 2°, the center of the spike rod and the reserved hole The deviation of the center position shall not exceed 2mm. Lay the liner and rubber backing plate, and the protruding edge of the backing plate should buckle the sleeper bearing platform. Install spring bars, flat washers and nuts. Tighten the nut so that the bottom of the front end of the middle part of the elastic bar must be in contact with the gauge baffle or keep the torque at 100N.m to 140N.m. After assembly or during maintenance, due to the manufacturing deviation of rails, sleepers and fasteners, rail wear, backing plate bias, etc., when it is necessary to adjust the gauge, different numbers of baffle seats and gauge baffles can be exchanged. Most of the railways and other rail transits use spring-type buckle parts. The main forms of my country's spring buckle parts are: bolt-mounted omega-structure springs, such as type I and type II springs used in the world, WJ-2 spring clips, etc.; when purchasing railway clips, reliable manufacturers should also be selected, so as to ensure the quality and service life of the clips.
