Railroad switches are actively used for linking railway tracks. Due to the design features, a system of this kind ensures reliability, as well as the integrity of the track on the way of moving the train. In addition, translations help to move the train from the railway to another. The railway tamping tool happens to be one of the essential steps here.
Places of transfer at the intersection, as well as the connection of rails are classified by:
- Type of rails,
- Brand of crosses.
Turnouts are also distinguished by wits, frame rails and designs of translation devices. The classic turnout is made of the following elements:
- Transverse bars,
- Crosses, which consists of guardrails, as well as one core,
- Arrows, including 2 frame rails, as well as a mechanism and 2 movable wits,
- Counter rails guiding the wheels into special troughs of the crosspiece,
- Connecting threads located between the rails, as well as the cross.
To change the composition route, the mechanism gradually squeezes the wit, which is located near the rails and presses the element that was pressed earlier. The wit is equipped with a specialized profile. Its smaller part is called wit. The end is called the root. Wheel pairs are transferred by an arrow from a direct way to a lateral then back. The correct maintenance of the railway track involves regular checking of the status of transfers.
Assessment of the condition of the upper parts of the railway tracks includes the following activities:
Maintenance of bars and sleepers: in the event that cracks have formed, the ends of the sleepers are pulled together to prevent their development, as well as the bars with steel wire, and special screws. If the bars, sleepers are made of reinforced concrete, a polymer-cement mortar is used to eliminate cracks. Initially, elements are cleaned of contaminants and other particles. After this, a solution consisting of water, sand, as well as cement and a special emulsion is applied.
Rail track maintenance: necessary to maintain the location as well as the relationship between web elements. Specialists eliminate deviations in level, as well as eliminate gaps in joints, clearances are adjusted, tightened, and then bolts are lubricated twice a year. The wrinkled ends of the rail are leveled and carefully ground,
The content of fasteners: specialists tighten the butt bolts in time, and also control that the lining rests on the sleepers. For this, screws are tightened and crutches are hammered on wooden sleepers, bolt tightening is checked. In the process of such operations, it is necessary to ensure that the bonds do not move under the rails. Masters use a special key for screwing. In this case, all worn out, severely damaged structural elements are replaced.
The content of the ballast: it must be constantly maintained in perfect condition. This eliminates unnecessary particles, small debris. Works are carried out aimed at preventing the appearance of grass on the surface of the tracks. Properly carried out work ensures the departure of water away from the path.
Overhaul of crossings.
Overhaul of crossings, as a rule, is carried out in conjunction with reinforced overhaul, overhaul or average repair of the track. During the overhaul of crossings, the following works are performed: replacement of the flooring, the construction of which is established by the Instructions for the device and maintenance of crossings, as well as standard designs.
