Cloud type rail

Abstract

The invention discloses a cloud type rail. The cloud type rail is characterized in that the cloud type rail is composed of a middle supporting steel plate assembly and two cloud rail plate assemblieslocated on the two sides of the cloud type rail; the supporting steel plate assembly is composed of an upper steel plate (1) and a lower steel plate (2); each cloud rail plate assembly comprises a center rib plate (3), the two sides of the center rib plate (3) are provided with U-steel (4) correspondingly, one side of the U-steel (4) is connected with the upper steel plate (1) and the lower steelplate (2), the other side of the U-steel (4) is connected with a bottom plate rib plate (5), and the upper ends and the lower ends of the bottom plate rib plate (5), the U-steel (4) and the center ribplate (3) are provided with an upper panel (6) and a lower panel (7); the tops of the upper panel (6) are provided with cloud rail plates (8), and the tops of the cloud rail plates (8) are provided with a plurality of uniformly distributed grooves (9); a plurality of uniformly distributed reinforcing ribs (10) are arranged in the length direction of the cloud type rail, and the reinforcing ribs (10) are simultaneously connected with the upper panels (6) and the cloud rail plates (8).

Description

technical field [0001] The invention relates to a supporting structure for a heavy-duty device, in particular to a cloud-shaped track. Background technique [0002] In the translation and transportation of equipment above 10,000 tons, ordinary I-steel rails (train rails or crane rails) are traditionally used to form super-heavy-load moving systems. Since the upper surface of the ordinary rail is a circular arc, the main reason is to ensure that the top of the arc is in contact with the wheel, and the belly of the rail is under pressure instead of bending force. The thickness of the belly of the I-shaped structure is small and cannot bear the huge side curvature. The wheel must be round, and the contact between two circular arcs is theoretically a point contact. After being stressed, elastic deformation occurs, which is a small round surface. The contact area is small and the contact stress is large. When the wheel is overloaded, contact fatigue pitting occurs on the surface...

AI Technical Summary

Problems solved by technology

Since the load is transmitted from the axle to the wheel through the bearing, the axle and the bearing are both large when the load is heavy, which determines that the ordinary rail heavy-duty transport vehicle has a large volume and complex structure, and the cost of manufacturing, operation and maintenance is high.

At the same time, the track used by this structure still has problems such as high cost, immovable track, and high ground infrastructure cost, so it becomes the bottleneck of super-heavy-load transportation.
