Abstract
The present invention provides a movable point frog. In this application, quasi-continuity of rails is achieved at the frog, so that a gap in the frog is eliminated, vibration and noise are reduced, and transverse impact of wheels is eliminated. Guard rails do not need to be disposed. The frog itself does not limit the speed of a train running on a main line and a branch line. Therefore, the train running on the main line can pass through the frog without reducing the speed. A relatively small curve radius and a relatively large frog angle may be adopted for the branch line. Compared with integrally cast frog equipment in the prior art, all the components in this application are detachably connected, and therefore can be simply mounted, easily maintained, and produced in batch.
Claims8
A movable point frog, comprising a frog assembly and a wing rail assembly, wherein the wing rail assembly comprises a first wing rail and a second wing rail that are symmetrically distributed;
- the frog assembly comprises a frog solid body, a first fixing bottom plate, a traction apparatus, a first exit rail detachably connected to the first fixing bottom plate, a second exit rail detachably connected to the first fixing bottom plate, and a rotating shaft fixedly disposed at the first fixing bottom plate, wherein the first exit rail and the second exit rail are symmetrically distributed, the first exit rail and the first wing rail are located on the same side, and the second exit rail and the second wing rail are located on the same side;
- and the frog solid body and the first fixing bottom plate form a rotating mechanism via the rotating shaft, the traction apparatus is drivingly connected to the frog solid body and enables the frog solid body to rotate around the rotating shaft, when one side face of the frog solid body abuts against the first wing rail, the other side face of the frog solid body is flush with the second exit rail, and when one side face of the frog solid body abuts against the second wing rail, the other side face of the frog solid body is flush with the first exit rail.
