Rail limiting device of heavy railway mechanical platform platform plate

Abstract

The invention discloses a rail limiting device for a platform plate of a heavy railway mechanical platform. The platform plate comprises an upper panel and a lower panel. More than two rail limiting devices are mounted between an upper panel and a lower panel of the platform plate; limiting holes in one-to-one correspondence with the rail limiting devices are formed in the lower panel; the rail limiting devices can do telescopic motion; when the platform plates are in a transportation state, more than two platform plates are stacked together, and the rail limiting devices are in a retraction state and are positioned in the platform plates; when the platform plates are in an assembled state, the rail limiting devices extend out of limiting holes of the platform plates; the platform plates are placed on the rails, and the rail limiting devices extending out of the platform plates are tightly attached to the side faces of the rails to limit the platform plates. According to the invention, the servicing and erecting efficiency can be improved and the assembling and adjusting strength can be reduced.

Description

technical field [0001] The invention belongs to the technical field of heavy-duty railway mechanized platforms, and in particular relates to a rail limiting device for platform slabs of heavy-duty railway mechanized platforms. Background technique [0002] At present, in order to meet the passability of vehicles with large turning diameters, my country's heavy-duty railway mechanized platforms are designed with multiple platform slabs as transitional connection sections. None of the existing platform boards is equipped with a rail limit device, so it is difficult to accurately align the platform boards when they are erected and assembled on the rail surface, resulting in repeated displacement and alignment of the platform boards during the entire assembly process, and the labor intensity of the erectors is high. The operation time is long and the operation efficiency is low. Contents of the invention [0003] In view of this, the present invention provides a rail limiting...
