The railway fastener manufacturer tells you that from a structural point of view, the elastic fasteners are mainly composed of elastic strips, spiral spikes, gauge baffles, under-rail pads, flat washers, and pre-embedded sleeves with shoulder sleepers positioned in prestressed concrete. Tube composition. In addition, in order to adjust the height of the rail, it also includes the height adjustment pad. So, what is the installation sequence of spring fasteners? In order to answer everyone's doubts, the railway fastener manufacturer will briefly explain the installation sequence of the spring fasteners.
The railway fastener manufacturer tells you to lay the under-rail pad, place the under-rail pad in the middle of the bearing rail surface, and the flange of the pad should buckle the rail bearing surface.
The railway fastener manufacturer tells you to lay the rails, and the rails are laid on the pad under the rail.
The railway fastener manufacturer tells you to install the gauge baffle, respectively install the gauge baffle on the outside and the inside of the rail, and place it between the two ears of the rail under the pad. Do not press the rail under the pad and check the gauge direction, such as If there is discomfort, replace the gauge baffle. Due to the manufacturing deviation of the rails, sleepers and gauge baffles, the gauge baffle of the specified number can not meet the gauge requirements or the gauge baffle cannot be installed in place, it can be replaced according to the actual situation. Special attention should be paid to the fact that the gauge baffle should not be pressed against the under-rail pad; the railway fastener manufacturer tells you that when installing the gauge baffle, you must not violently knock the gauge baffle into place.
The railway fastener manufacturer tells you to install the elastic strip, place the elastic strip in place, cover the spiral spike with a flat washer and coat the threaded part with railway-specific protective grease, then screw into the casing to tighten the elastic strip. The railway fastener manufacturer tells you that the fastening of the elastic strip is subject to the contact between the lower jaw of the middle of the elastic strip and the rail. The criterion for judging whether the spring bar is installed in place is that the lower jaw of the front end of the spring bar is in contact with the rail, and the gap is not more than 0.5mm.
The railway fastener manufacturer tells you that this is the installation sequence of the elastic fasteners. I hope this information can provide you with some help. Of course, after installing the elastic fasteners in this order, in order to ensure the installation effect of the elastic fasteners, it is necessary to make appropriate adjustments, such as adjusting the gauge and track direction, and adjusting the height of the rail.
