Detailed Description
The tramcar small-number curve symmetrical turnout structure as shown in figure 1 comprises a stock rail 1 and a switch rail 2, a sliding bed platform 3 positioned at the bottom of the switch rail 2 is also arranged in the turnout, a switch machine 4 for driving the switch rail 2 to work is connected on the switch rail 2, in order to prevent the train from derailing in the running process, an anti-drop mechanism is also arranged in the turnout, the anti-drop mechanism is provided with a pair in a transition area where the switch rail 2 and the stock rail 1 are connected, the switch rail 2 is respectively limited, the non-working surface of the switch rail 2 after being limited can realize the function of limiting and anti-drop on the inner wheel back of the wheel, the heel end of the switch rail 2 in the turnout is fixed, a top iron mechanism is arranged on a sleeper close to the heel end, the top iron mechanism is abutted against the rail waist position on the outer side of the switch rail 2, so that the heel end of the switch rail 2 is kept consistent with the track gauge between the stock rail 1, the track gauge is prevented from being changed when the switch rail 2 works, the stock rail gauge is arranged at the stock rail position where the top, if adopt traditional top iron (leaning on through a straight-bar promptly and realizing spacing between stock rail and switch rail), then can not satisfy the rigidity requirement, thereby switch rail 2 makes traditional top iron produce deformation easily at the during operation and changes gauge and switch rail heel span, and the top iron mechanism among the adoption this technical scheme, because top iron mechanism fixes on slide plate, need not the cooperation with the adjacent stock rail of this switch rail, its rigidity is better, and the location is more accurate reliable, guarantees gauge and the requirement of switch rail heel span in the symmetrical switch of small-size sign indicating number curve.
The anti-falling mechanism comprises a mounting frame 5 and an anti-falling guard rail 6, the anti-falling guard rail 6 is arc-shaped and consistent with the bending direction of the switch rail 2 at the contact part of the switch rail 6 and the switch rail 2 as shown in fig. 2, the adjacent stock rails are gradually kept away from the tip to the heel of the switch rail 2, the working surface of the switch rail 2 at the non-working position abuts against the anti-falling guard rail 6 after the switch rail 2 at the non-working position moves, the anti-falling guard rail 6 can limit the position of the switch rail 2 at the non-working position and simultaneously play a reinforcing role, and the non-working surface of the switch rail 2 at the non-working position provides a limit for the wheel inside wheel back to prevent the wheel from falling off. In order to make the anti-drop guard rail 6 provide better supporting force for the point rail 2, the outline of the contact part of the anti-drop guard rail 6 and the point rail 2 is matched, so that the top of the point rail 2 is completely attached to the anti-drop guard rail 6.
