Most of the existing off-highway wide dump trucks use welding brackets, and the problems of fracture, failure and the like are most frequent under mining area working conditions.

Disclosure of Invention

The utility model aims to solve the technical problems of the prior art and provides an off-highway wide dumper forming support assembly, which aims to solve the problems that the support type devices in the prior art are low in connection strength and are easy to damage under severe and complex working conditions of mining areas.

In order to solve the technical problem, the utility model provides a shaping bracket assembly of an off-highway wide dump truck, which comprises a bracket body and a rib plate, wherein the bracket body is bent and connected into a dustpan-type structure by a shaping bent plate, and is provided with a second surface positioned at the rear part, a third surface positioned at two sides and a first surface positioned at the bottom; the rib plate is fixed between the first surface and the second surface of the bracket body through welding.

The forming bending plate is of an integral stamping bending structure and comprises four bending lines, and the forming bending plate is connected with the forming bending plate through welding after being bent along the bending lines to form a support body structure.

The first surface and the second surface are provided with a plurality of groups of connecting holes for connection and fixation.

The first surface is provided with a via hole or a wire through hole.

The third surface is provided with a connecting hole for connecting and fixing different purposes.

The forming bracket assembly is connected with the connected piece through the first surface, the second surface and the third surface by bolts and nuts.

The beneficial effects are that: the molding bracket assembly of the off-highway wide dump truck has smaller installation space requirement, greatly increases the connection strength, is stable and reliable, is suitable for complex and severe mining area working conditions, and is not easy to damage; the assembly is convenient, the universality is good, the connection mode is simple, bolts and nuts are adopted for connection and fixation, and a good bearing effect is achieved.
