Description

Dump truck box

Technical Field

The utility model particularly relates to a dumper box body.

Background

The dump truck refers to a vehicle which unloads cargos by self through hydraulic or mechanical lifting. Also known as dump trucks. The hydraulic lifting device consists of an automobile chassis, a hydraulic lifting mechanism, a cargo compartment, a power take-off device and the like. The carriage of the self-discharging vehicle is divided into backward tilting and lateral tilting, the piston rod is controlled to move through the control system, backward tilting is common, the piston rod is pushed to tilt the carriage, and a few carriages are tilted in two directions.

The side plate of the traditional dumper has two structures:

the first one is: the connecting structure of the side carriage plate and the bottom plate of the traditional rectangular carriage is formed by welding as shown in the figure I, and the structure has the following defects: 1. the welding quantity is large, four welding seams of a, b, c and d shown in the first drawing need to be welded in the rectangular box, and the production efficiency is low; 2. the middle side sliding plate 3 needs to be welded when the side plate and the bottom plate are welded, half of the thickness of the side sliding plate 3 is smaller than that of the bottom plate, welding seams a and b are not easy to weld if the thickness of the side sliding plate 3 is too large, and therefore when loading large-block-shaped-hardness goods, the impact force on the side sliding plate 3 and the welding seams is large, the sliding plate is easy to damage, the welding seams b crack, and the service life is prolonged.

The second method is as follows: the connecting structure of the side compartment plate and the bottom plate of the traditional U-shaped compartment is shown in the second drawing. The side carriage plate 1 and the bottom plate 2 are in a lap joint state and are formed by welding seams e and f, the apron plate 5 is welded on the side carriage plate 1, the main function is to improve the appearance visibility of the U-shaped carriage, and the apron plate 5 is welded with the side carriage plate 1 through the welding seams g and h. The disadvantages of this structure: 1. four welding seams of e, f, g and h need to be welded, the welding quantity is large, and the production efficiency is low; 2. the skirtboard 5 only plays a role in shielding, and is easily damaged by deformation caused by collision in the running process of the carriage.

Aiming at the problems in the prior art, the utility model provides the dump truck box body, which not only has a small number of welding seams and can improve the production efficiency, but also can improve the torsional strength and the anti-expansion capacity of lifting a container.

SUMMERY OF THE UTILITY MODEL

In view of the above, the present invention provides a dump truck body which can improve the production efficiency during welding.

In order to solve the technical problems, the utility model provides a dump truck box body which comprises a front box plate, a rear box plate, a left box plate, a right box plate and a bottom plate, wherein the left box plate and the right box plate are symmetrical in structure, the lower ends of the left box plate and the right box plate are bent to form L-shaped bent parts, the bent parts are welded with the bottom plate, and a connecting seat used for being fixedly connected with a truck frame is arranged on the bottom plate.

Furthermore, the front box plate is fixedly connected with the left box plate, the right box plate and the bottom plate, and one end of the front box plate, which corresponds to the vehicle head, is fixedly connected with an inverted L-shaped baffle.

Furthermore, a reinforcing rib plate is arranged at the joint of the front box plate and the baffle.

Furthermore, the rear box plate is hinged on the bottom plate through a hinge piece.

Further, the articulated elements includes fixing base, articulated seat and connecting piece, the fixing base is articulated with articulated seat, and articulated seat is articulated with the connecting piece, and the connecting piece is used for fixing the back railway carriage.

Furthermore, the connecting seats are two.

Furthermore, the upper end of the left box plate and the upper end of the right box plate are respectively provided with a handrail.

The technical scheme of the utility model has the following beneficial effects:

1. only need left boxboard, right boxboard and bottom plate weld can, can make welded number of times reduce like this, can make production efficiency obtain improving like this.

2. The anti-expansion capacity of the carriage of the dump truck can be increased through the hinge piece.
