Repair means for typical and composite open-wagon bodies

Abstract

Considered means of the typical and composite open wagon bodies repair, which will prevent the possible loss of bulk cargo and increase the level of the train traffic safety. Defects of open wagon bodies were identified and analyzed. Malfunctions and damage to wagon bodies are diverse and depend on the operating conditions of the wagon and its design features. The most typical malfunctions for all types of wagons are cracks, holes, deflections, dents, corrosion damage to metal parts and rotting of wood, as well as damage to the fastening parts of door sides, hatch covers, bodies. Considered technical requirements for nodes and parts of freight wagons in operation. Malfunctions of bodies and frames of freight wagons were analyzed. When designing highly loaded parts with complex geometry, the application of combined solutions is considered. Typical and prospective (composite) designs of open wagon bodies were also considered. The work examines the equipment for the repair of typical and composite open wagon bodies. The wagon repair machine for operational depots VRM-E, which is designed for mechanization of production, current uncoupling repair of freight wagons at the PTO and is designed to correct defects in the open wagon bodies, the considered open wagon tilter is mobile, which is designed for positioning the body of the open wagon in two directions in the conditions of wagon repair depots and wagon-building enterprises. Installation for fixing the upper binding frame of open wagons that can be used in wagon repair depots. Installation which is intended for correcting all major types of deformations of the upper binding frame of an open wagon, installation of straightening the side walls of the body of the open wagons. Calculations for the strength of the semi-wagon body in the empty state under repair loads were also conducted.
