MODULARIZED LIGHT-WEIGHT INTERNAL COMBUSTION LOCOMOTIVE BODY

摘要

A modularized light-weight internal combustion locomotive body. The locomotive body is composed of a vehicle underframe (1), a fuel tank (4), a steel framework (2) and a modularized casing (3), wherein the vehicle underframe is welded by a fish belly box-type longitudinal beam (5) and a cross beam (6); the fuel tank is mounted in the middle of the underframe; a steel frame mounting base (7) is welded to the upper portion of the fish belly box-type longitudinal beam; a partition wall mounting base (8) is welded to the upper portion of the cross beam; the steel framework is welded by a steel frame (9) and a partition wall (10); the steel frame mounting base, the partition wall mounting base, the bottom end of the steel frame and the bottom end of the partition wall are all provided with bolt holes (18); the vehicle underframe and the steel framework are connected by means of bolts (19); the modularized casing is welded from a sheet steel (11) and a profile (12); a threaded block (13) is welded to the profile; and the modularized casing is connected to the steel framework by means of the bolts. By means of the internal combustion locomotive body, the weight of the locomotive body is greatly reduced, and the production and maintenance are more convenient and economical.
