Special device for transporting superlong steel rail and its transportation scheme

Abstract

The present invention discloses special-purpose equipment for transporting extra-long steel rail and its transporting method. Said special-purpose equipment includes locking seat frame, sliding seat frame, partition beam and fastening device. The described locking seat frame and sliding seat frame respectively contain base beam with bearing action, its two ends are vertically downwards welded with end retaining channel steel respectively, and guide channel steel positioned in the upper portion of base beam, its, inner side is welded with a supporting seat. Said transporting method includes the following steps: mounting locking seat frame and sliding seat frame, successively arranging first layer of steel rails and other layes of steel rails, finally stretching and fixing.

Description

technical field [0001] The present invention relates to a transportation method for cargo transportation, in particular to a transportation method for transporting super-long steel rails (50m to 100m). Background technique [0002] At present, domestic railways use ordinary flat cars to transport steel rails with a length of 25 meters. The special bogie for six supports includes 1 pair of bogies and 4 slides, each pair of bogies is composed of 2 upper frame bodies and lower frame bodies, one of the lower frame bodies is a dead center plate, and the other is a live center plate; The upper frame body of the bogie can rotate relative to the lower frame body; the two bogies are respectively placed in the middle of the two flat cars. Four slides are placed above the center pin of each vehicle bogie of the two flat cars. In addition to supporting the rail, the six-support bogie can drive the transported rail to rotate relative to the vehicle when the vehicle passes through the c...

Problems solved by technology

[0004] The purpose of the present invention is to aim at the utility model patent whose notification number is CN2656247Y, where the longitudinal locking function of the locking seat frame fails during the actual transportation process, the displacement of the rail on the vehicle is relatively large, and there is random movement of the partitions, and the displacement exceeds the limit. problems, resulting in the failure of the patent to achieve the expected goal of restraining the rails to make them bend naturally when the vehicle passes through a curve, and failing to meet the operational safety requirements of the vehicle, resulting in the failure of the overall bundling transportation method; in order to overcome these defects, it is necessary to re- Development of a transportation method that meets transportation safety requirements and is practical for transporting extra-long rails
