Flexible connection rail of hinged type between sleepers

Abstract

The invention provides a flexible connection rail of a hinged type between sleepers. In the invention, steel rails are fixedly connected with the two sides of the surfaces of the sleepers; a plurality of sleepers are connected to form the rail; the steel rails are short steel rails and the lengths thereof are 100-130% of the widths of the sleepers; the sleepers are strip-shaped rigid sleepers; hinge seats are arranged at the middle positions between the two side surfaces of the sleepers; every two adjacent sleepers are hinged by a hinge shaft and a gap is arranged between every two adjacent sleepers; and the two ends of the sleepers are respectively provided with a set of sleeper push-pull mechanism. The invention has the beneficial effects that: the intersection points of the adjacent steel rails are concyclic, namely, the vehicle running route is similar to a circular arc on a bent flexible rail, thereby meeting the safety standard requirement; the flexible rail is integrally bent to deform without generating internal stress, therefore, the service life of the rail is prolonged; the rail has simple structure form, standardized components, convenient mounting and dismounting, practicability and economy; and the rail can be applied to the ship-shore connection bridges of the rail transport so as to improve the compatibility or the generality between the ship and the bridge.

Description

Technical field: [0001] The invention belongs to the field of transportation engineering facilities, and in particular relates to a railway ferry trestle bridge ship-shore connecting track. Background technique: [0002] In the railway ferry transportation system, the trestle with rails is a key device connecting the ship and shore. The traditional technology is to set fixed rails and ordinary turnouts on the trestle. Because the traditional technology is to set fixed tracks and turnouts on the trestle, the connecting trestle lacks flexibility, and the applicability to different types of ferries is poor, which is a bottleneck technology that restricts the further development of railway ferries. In order to improve the adaptability of the railway ferry trestle to the ship type and improve the connection form between the fixed track on land and the track on the deck, the patent No. ZL97 2 12573.6 proposes a flexible connection composed of short rails and reserved expansion ga...

Problems solved by technology

This kind of track uses the elasticity of the rail to realize bending, and the structure is simple. The disadvantage is that the force or moment required for bending the rail is relatively large.
