Multiple cross points

Double cross points is to shorten the station throat length and decrease tool use, good equipment to improve the efficiency of shunting. The length is slightly longer than the single turnout, and its role is equivalent to two groups to the single switch, it can shorten the length of the station, arrived at the station, marshalling yard and special field of cohesion in the throat area of double and multi line interval, the double cross points with crossover, is more obvious.

Doubleslip switches like X shape combination in fact equivalent to four single turnout and a diamond shaped cross. In addition, there is a cross device, commonly known as diamond cross. It consists of two groups and two groups of acute frog obtuse frog, but no switch, so can not be transferred between the track line. If the two points of the X shape of the double point switch are respectively connected with the following two points, the crossing line is crossed. It can not only open more directions, but not much land, so often used in the station.

The structural composition of the compound turnout

The two pairs of common acute frog;

The two groups of movable rail obtuse frog;

The four straight rail and four curved rails;

The six curved rails;

The eight connecting rails and connecting parts;

Such as wooden sleeper, electric switch mechanical and electrical equipment.

Laying of double entry points

1, venue: laying turnout, be sure to smooth the site, measuring the turnout center pile.

2, laying pillow: laying should be in the double crossing the central axis of the pull line. And each of the bifurcated pillow in the middle line. In order to ensure that each sleeper is perpendicular to the central axis, the center line of each of the bifurcated pillows is coincident with the central axis.

3, different manufacturers of doubleslip switches are slightly different, to read the instructions and technical requirements of the design before laying. When installing the switch fittings, place the position of the fork, the length of the rail and the number of the accessories. And pay attention anyway.

4, the lift rails, movable core rail according to the drawings indicate good size adjustment.

5, the position of the insulation joint should be determined according to the design drawings and then install.

The products have been exported to the United States, France, Canada, Indonesia, Russia, Vietnam, Australia, South Korea, Iran and other countries, to obtain customer acclaim.
