Detailed Description
The symmetrical switch structure of the small-number curve of the tram, as shown in figure 1, comprises a stock rail 1 and a switch rail 2, a sliding bed 3 positioned at the bottom of the switch rail 2 is also arranged in the switch, a switch machine 4 for driving the switch rail 2 to work is connected to the switch rail 2, a drop-preventing mechanism is also arranged in the switch, a pair of drop-preventing mechanisms are arranged in the transition area where the switch rail 2 and the stock rail 1 are connected, the limit is respectively realized on the switch rail 2, the non-working surface of the switch rail 2 after the limit can realize the limit drop-preventing function on the wheel back of the inner side of the wheel, the switch rail 2 is fixed at the heel end, a top iron mechanism is arranged on the sleeper near the heel end, the top iron mechanism is propped against the rail waist position outside the switch rail 2, the track gauge between the heel end of the switch rail 2 and the stock rail 1 is kept consistent, the track gauge is prevented from changing when the switch rail 2 works, the position where the tip iron mechanism is arranged on the small-number curve symmetrical turnout is larger than the adjacent stock rail 1 because the gap between the switch rail 2 and the adjacent stock rail 1 is larger, if the conventional tip iron is adopted (namely, the limit is realized by abutting a straight rod between the stock rail and the switch rail), the conventional tip iron is easy to deform when the switch rail 2 works, so that the track gauge and the track gauge of the heel end of the switch rail are changed, and the tip iron mechanism in the technical scheme is adopted.
In the above structure, the anti-disengaging mechanism comprises a mounting frame 5 and an anti-disengaging guard rail 6, as shown in fig. 2, the contact part of the anti-disengaging guard rail 6 and the point rail 2 is arc-shaped and consistent with the bending direction of the point rail 2, the tip end of the point rail 2 is gradually far away from the adjacent stock rail from the heel end, the working surface of the non-working position point rail 2 abuts against the anti-disengaging guard rail 6 after moving, the anti-disengaging guard rail 6 plays a reinforcing role for realizing the limit of the non-working position point rail 2, and the non-working surface of the non-working position point rail 2 provides limit for the wheel back of the wheel inner side to prevent the wheel from falling when passing through the small section of the point rail. In order to make the anti-drop rail 6 provide better supporting force for the point rail 2, the contour of the contact part of the anti-drop rail 6 and the point rail 2 is matched, so that the rail top of the point rail 2 is completely attached to the anti-drop rail 6.
