Description
Blocking fixing device for railway flatcar Technical Field The utility model belongs to the technical field of railway flatcars, and particularly relates to a blocking fixing device for a railway flatcar. Background Railway flatcar is as the freight train of a no curb plate or low curb plate, in the freight transportation, often face the problem such as material slip in the in-process of carrying thing, material drop in the transportation. In order to ensure the stability of goods in the transportation and carrying process, blocking structures are usually required to be arranged on two sides of the flatcar, and materials are limited and fixed. However, the existing blocking devices have a number of disadvantages in use. At present, the blocking device used for part of railway flatcars is fixed in structure and can not be folded, and is exposed on two sides of a base plate for a long time, so that the material loading and unloading efficiency is affected when the railway flatcars are not used, interference with mechanical equipment or personnel is easy to occur, and certain potential safety hazards exist. Other devices can be adjusted or folded, but the structure is complex, the assembly and the disassembly are complicated, the adjustment process depends on manual accurate alignment, the efficiency is low, the reliability is poor, the conditions of loosening, falling and the like are easy to occur under the frequent operation condition, and the service life is influenced.
