500m long rail train

Abstract

The invention discloses a 500m long rail train, comprising 37 flat cars, wherein a chain block rail clip hook for suspending rails is arranged on a car frame of each flat car, and the chain block rail clip hook comprises a chain block and a clip hook connected with the bottom end of the chain block. The 500m long rail train is characterized in that the chain block rail clip hook for hooking the rails is installed on the side of the flat car, and the block chain is driven by a chain hoist to lift the clip hook to hang a rail as long as 500m onto the flat cars, thereby realizing transportation of long rails. The 500m long rail train is simple in structure and convenient in use, operation and maintenance, and utilizes the existing flat cars, thereby having low purchase, manufacturing and maintenance costs, quick conversion speed and high efficiency. The block chain is directly hooked with the clip hook, so that the suspension length can be reduced below 0.9m under the condition of satisfying the hooking intensity. The 500m long rail train has a compact structure, greatly reduces occupied space, satisfies a hanging space as compared with the existing flat cars with a limited-height, and also has the characteristics of convenience and fastness in assembly.

Description

technical field [0001] The invention relates to a 500m long rail train, which belongs to the technical field of railway rail transportation. Background technique [0002] The railway is an important national infrastructure, the main artery of the national economy, and the backbone of the transportation system. It is a transportation mode with large transportation capacity, resource conservation, and environmental protection. It shoulders an important historical mission in the process of building a well-off society in an all-round way. Railways should promote rapid and sound economic and social development and meet the needs of national defense construction. With the continuous development of the economy, the requirements for railway construction are getting higher and higher. In order to meet the rapid transportation of railways, the long rails need to be transported to the designated location for laying before laying the tracks. The existing technology is often used in the ...
