Switch is the throat of rail transit, switch is very important, switch disease and slide damage more obvious. According to the classification of diseases, through the in-depth study of force analysis, diseases caused by various factors have been found at this stage, aiming to improve the life and safety factor of the equipment by adapting to the special rectification and elimination of medicine. The following details how to maintain rail tie plate railway switch manufacturers?

How to maintain the rail tie plate every day?

Laying multiple intersections can reduce the number of single switches and reduce the area of the station, but the structure is complex, there are many channels, the tracks are involved with each other, and the size of each part has high technical requirements. The gauge reduction of each part of the obtuse horn frog has special requirements, and it is often difficult to keep it intact if there is improper maintenance. In the maintenance and maintenance of multiple intersections, we must first master the equipment, accurately grasp the size of each part, check often, analyze carefully, and then take effective methods to do the work.

(1) Start the road: the master is good, the turnout is small, generally find the high point as the control point, and then according to the control point will be obtuse Angle and fork flat, towards both ends respectively flat. Webmaster is not good, pray a large amount of the case, can be from side to side. A prayer amount is too high to prevent "drying". At the beginning of the level, the switch should be flattened according to the middle two tracks (or the two curved base track vertices). One is large, the other is to prevent the phenomenon of reverse superhigh.

Strengthen the end of the switch rail. It is necessary to strengthen the firm of the main points such as the end, the end, the acute Angle, the fork, and so on, to prevent the disease of the switch rail and the half height caused by the low joint and the low center. Within the range of the sharp rail, it should be tamped one by one to avoid empty boards. Use a pick if necessary.

(2) Dial the track: First of all, the cross line of the two main driving directions and the line connected at both ends are greatly extended, the fork is corrected, and then the center track is sharp with two acute angles. Check and check the end string (long axis), guide curve offset, check the out-of-limit area, and correct before changing the road.

(3) Rerouting: First change the gauge of the intersecting lines, then improve the inner circumference of the curve based on the induced curve periphery, and then check and correct the spacing of each part. The basic rail should be repaired in time when the bending is insufficient or worn.

(4) To prevent joint electricity: intersection forks are spread on the stationmaster, and we should always pay attention to the signal display caused by Lien Chan when working. According to the actual requirements, at the end of the two prongs. Heat MATS, tilt slides and short slides were installed. When working, do not place tools between the two prongs to avoid a battle. On the airway, it is necessary to prevent the switch rail tie rod and connecting rod from connecting with the bottom of the upper guide rail, strengthen the stamping of the part, and prevent the switch rail or basic guide rail from jumping or sinking when the vehicle passes. This will produce smoke electricity. Familiar with track circuit layout, strictly abide by the relevant regulations of track circuit turning work.

(5) Prevent poor 4mm blocking

1) Cross switches and front and rear lines should be evaluated, the direction is straight, the unqualified gauge and the spacing of each part should be corrected, the deep rail is straight, the bending vector does not meet the requirements of the basic rail, grinding the fertilizer edge of the sharp rail and the basic rail, and keeping it tight.

2) Add components such as special gauge rods, supports, and transverse flapboards to enhance lateral stiffness in the range of the center shaft and switch rails, prevent lateral movement of the basic track, and repair, modify, or replace faulty components while maintaining a fixed spacing distance.

3) Strengthen the climb lock of the switch and the front and rear lines, in addition to the use of observation pile inspection, you can also use the structural characteristics of the switch itself for inspection. Like a sharp rail. The end should use the "four-point line", the tip rail and the end should use the "four-seam line" and so on.
