Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of dump trucks, and in particular relates to a rectangular box rear plate structure mounted on a wide-body mining truck. Background Art
[0002] The box back plate installed on the mining truck is generally a frame structure with surrounding horizontal and vertical beams, with one or two horizontal beams built in, and two to four vertical beams between the horizontal beams. These horizontal and vertical beams are welded to the flat plate structure back plate to form a complete back plate assembly structure. Since the back plate of this structure is a flat plate, the overall rigidity is relatively small. Although there is a significant improvement after welding the vertical beams to strengthen it, the welding workload is large, and the welding of the vertical beams and the horizontal beams is prone to cracking when facing the impact of large stones.

[0005] A rear plate, the rear plate is in an I-shape, and comprises an upper plate, a middle plate and a lower plate, the middle plate having a concave plate with a plurality of horizontal bending lines, and the concave surface of the concave plate faces the rectangular box;
[0006] A left column and a right column, wherein the left column and the right column are respectively arranged at the left end and the right end of the middle plate, and the two ends of the upper plate and the lower plate are welded to the left column and the right column;
[0007] An upper side beam and a lower side beam, both of which are arranged on the outer side of the rear plate, the upper side beam is welded to the upper plate, and the two ends of the upper side beam are respectively welded to the side surfaces of the left pillar and the right pillar, the lower side beam is welded to the lower plate, and the two ends of the lower side beam are respectively welded to the side surfaces of the left pillar and the right pillar.
[0008] The utility model bends the rear plate and changes the shape of the rear plate from a two-dimensional structure to a three-dimensional structure, so as to improve the structural strength thereof. No additional vertical beams are needed to increase the structural strength, and the deadweight and welding workload can be reduced, thereby increasing the service life.
[0009] Furthermore: the inner sides of the left column and the right column are both provided with column reinforcement plates, and the column reinforcement plates are respectively used to connect the left column and the left side of the middle plate, and to connect the right column and the right side of the middle plate.
