Embodiment Construction

[0023] Past examples such as Figure 4 As shown, the rotating handle 2 is not an integral rod along the length direction, but consists of a pair of rod parts 2a, 2b, which can be arranged in the middle part to generate mutually insulated signal parts between the switch rails, and use bolts and A combined rod connected by nuts, etc. Since the present invention has nothing to do with the aforementioned components, descriptions and illustrations related thereto are omitted.

[0024] The term "spherical band" described in the present invention. The term can refer to both figure 1 , 2 , 4, 5, the entire ball zone of the convex part 3 extending from the connecting block 32 to its outer edge can also represent as Figure 7 , 8 , 9, and 10, the outer edge of the convex part 3 is cut vertically to form most of the ball bands, or part of the ball bands in the strict sense, and the corresponding part is the hemispherical hole 4a.

Abstract

PROBLEM TO BE SOLVED: To prevent a derailment accident that could take place when a tongue rail and a connecting rod are separated due to switchover force exerted by the connecting rod to the tongue rail at a time of tongue rail switchover (lateral motion of the connecting rod and pressing of the tongue rail onto a stock rail) and vibration of the tongue rail caused by a passing train and conveyed to each bolt and nut connecting a U-shaped metal fitting and a connecting plate, which result in loosening and fall-out of the bolt and nut.SOLUTION: At a fitting portion 5 for a tongue rail 1 and a connecting rod 2, the tongue rail 1 and the connecting rod 2 are connected by protrusion-recess engagement between a protruded member 3 and a recessed member 4, the protruded member being formed in a spherical belt form and the recessed member having an externally fitted portion 40 corresponding to the protruded member 3 of the spherical belt form.SELECTED DRAWING: Figure 1

Description

technical field [0001] The invention relates to a connecting device of a switch rail and a turning handle of a railway turnout. Background technique [0002] The previous turnout structure, such as Figure 12 As shown, each end of the connecting plates a1, a2 is connected and fixed with each switch rail R1, R2 by bolts and nuts, and the other end of the connecting plates a1, a2 is embedded and fixed in the rotating handle c, and the side is a U-shaped metal fastener e1, e2, and are fixed by bolt b1 and nut b2, so that the switch rails R1, R2 and the rotating handle c are integrated. In this way, as shown by the arrow, the clutch of the switch rails R1, R2 and the basic rails r1, r2 can be switched by moving the turning handle c left and right. [0003] The switching force transmitted from the turning handle to the turning handle generated during the switching of the turning handle (the left and right movement of the turning handle causes the pressing of the turning handle t...
