From a structural point of view, elastic rail spikes are mainly composed of elastic rail spikes, screw spikes, gauge baffles, underrail plates, flat washers, and embedded bushings located in prestressed reinforced concrete with shoulder pillows. In addition, it is necessary to adjust the height and height of the rail, and it also contains the adjusting pad. So, what is the installation order of elastic rail spikes? In order to explain your concerns, I will briefly explain to you the order in which elastic rail spikes are installed. 1. Lay the underrail plate, place the underrail plate in the middle of the bearing rail surface, and the boss of the backing plate should hook the bearing rail surface. 2. The rail is laid on the underside of the rail. 3. Install gauge baffles on both sides of the rail, add gauge baffles on the inner side, and place them in the middle of the two side ears of the underrail cushion plate, do not press the underrail cushion plate, check the gauge orientation, if there is discomfort, remove and replace the gauge baffle plate. Due to the manufacturing errors of rail, cement tie and gauge baffle, the gauge baffle with the required number is added, which can be replaced according to the specific situation if the gauge regulations are not taken into account or the gauge baffle can not be installed in place. It must be noted that the gauge baffle should not press the underrail plate; When installing the gauge baffle, do not strongly tap the gauge baffle to make it in place. 4. Install elastic rail spikes and place the elastic rail spikes in time. Cover the screw-type spike with a flat washer and coat part of the outer thread with railway safety protective vegetable grease. Then screw in the waterproof sleeve and tighten elastic rail spikes. Tightening of elastic rail spikes is standard with the middle front end of elastic rail spikes developing jaw to the rail contact. The criterion for determining whether elastic rail spikes are installed in time is that the middle front of the elastic rail spikes is developed when the jaw touches the rail and the gap does not exceed 0. millimeter. This is the order of installation of elastic rail spikes, looking forward to showing you some assistance. It is hoped that after installing elastic rail spikes in this order, in order to ensure the actual installation effect of elastic rail spikes, it is necessary to carry out moderate adjustment, such as adjusting the gauge and rail direction, adjusting the rail height and so on.
