Description

Carriage

Technical Field

The utility model relates to a carriage field, concretely relates to carriage.

Background

The frame of the traditional carriage is generally welded by a welding process, all edges of the frame are welded, so that the frame is high in machining cost and difficult to machine, the welding operation has adverse effects on the environment and machining workers, and the frame is deformed due to the welding process, so that the overall stability of the frame is affected.

Disclosure of Invention

In order to solve the problem, the utility model provides a carriage.

The technical scheme of the utility model:

the utility model provides a carriage frame, it includes crossbeam, perpendicular roof beam and longeron, its characterized in that, the frame still includes the connecting piece, and the connecting piece includes three faces, and first face and perpendicular roof beam face and face contact and rivet through the rivet, and the second face and crossbeam face and face contact and rivet through the rivet, and the third face and longeron face-to-face contact and rivet through the rivet constitute a square frame jointly.

Furthermore, the frame still includes the connecting piece, and the connecting piece includes three faces, and first face and vertical beam face and face contact and rivet through the rivet, and the second face contacts with the crossbeam face and rivet through the rivet, and the third face and longeron face-to-face contact and rivet through the rivet constitute a square frame jointly.

Further, the connecting piece still includes the fourth face, and the fourth face is connected with the third face, and with longeron face-to-face contact and through rivet riveting.

Furthermore, the junction of the third surface and the fourth surface is provided with a first reinforcing part and a second reinforcing part which extend, and the first reinforcing part and the second reinforcing part are arranged in a clinging manner.

Further, the connecting piece still includes the fifth face of being connected respectively with first face and second face, the sixth face of being connected respectively with first face and third face and with the second face with the seventh face that the fourth face is connected respectively.

A carriage comprises a carriage frame, wherein a bottom plate, a top plate, a left side plate, a right side plate, a front wall plate and a rear door plate are arranged on the carriage frame; the carriage frame is the frame; the rear door plate is formed by installing a door on a frame; the door is a double-door or single-door.

The utility model has the advantages of reasonable design and simple structure, and the vertical beam, the cross beam and the longitudinal beam are connected by the connecting piece to form a frame with stable structure, thereby avoiding the frame deformation caused by welding process reasons; the surface-to-surface contact and isomorphic rivet riveting are adopted, the number of bolts required for assembly is reduced, the contact area is increased, the deformation of the stand column, the cross beam and the longitudinal beam in the fixing process is avoided, and the overall structure of the frame is more stable and reliable.
