The technical scheme is further limited, the reinforcing groove is a trapezoidal dovetail-shaped groove, the depth of the groove is 50-150mm, and the width of the groove is 600-800 mm.
Further inject above-mentioned technical scheme, left side is strengthened the longeron and is strengthened the longeron structure the same with the right side, comprises the web of pterygoid lamina about last pterygoid lamina, lower pterygoid lamina and connection, and the upper pterygoid lamina can laminate with the bottom plate bottom surface, and the lower pterygoid lamina can laminate with the tank bottom surface of strengthening the groove.
The technical scheme is further limited, the left overturning auxiliary frame and the right overturning auxiliary frame are identical in structure and are composed of longitudinal channel steel and transverse channel steel which are welded with each other.
The technical scheme is further improved, and base plates are arranged between the left overturning auxiliary frame and the bottom plate and between the right overturning auxiliary frame and the bottom plate.
The technical scheme is further improved, and a cross beam is arranged on the bottom surface of the tail end of the bottom plate.
Has the advantages that: 1) compared with the traditional bottom plate assembly, the utility model has lighter weight and larger volume, and improves the utilization coefficient of the load capacity of the carriage body; but also saves energy, reduces consumption, reduces materials, reduces welding quantity and greatly reduces cost; 2) the product manufacturability is also ensured, the production efficiency is greatly improved, and the product quality is also improved; 3) the utility model discloses can reduce carriage height 50-120mm, make whole car focus reduce, improve whole car stability, but wide application in the tipper carriage bottom plate assembly of this type of structure.

Detailed Description
As shown in fig. 2, 3 and 4, a novel light-weight frameless self-discharging carriage bottom plate assembly comprises a bottom plate 1, a left reinforcing longitudinal beam 3, a right reinforcing longitudinal beam 4, a left turning auxiliary frame 5 and a right turning auxiliary frame 6, wherein a longitudinal reinforcing groove 101 is formed in the middle of the bottom plate, the left reinforcing longitudinal beam and the right reinforcing longitudinal beam are positioned on two sides of the reinforcing groove and connected with the reinforcing groove to form an integrated structure, the left turning auxiliary frame is connected with the left reinforcing longitudinal beam and the bottom plate to form an integrated structure, and the right turning auxiliary frame is connected with the right reinforcing longitudinal beam and the bottom plate to form an integrated structure;
as shown in fig. 2, 3 and 4, the reinforcing groove is a trapezoidal dovetail-shaped groove, the depth of the groove is 50-150mm, and the width of the groove is 600-800mm, so that the reinforcing groove has the advantages of light weight, high strength and increased volume;
as shown in fig. 2, 3 and 4, the left reinforcing longitudinal beam and the right reinforcing longitudinal beam have the same structure and are composed of an upper wing plate, a lower wing plate and a web plate for connecting the upper wing plate and the lower wing plate, the reinforcing longitudinal beam is similar to a Z-shaped structure, the upper wing plate is fixed by welding after being attached to the bottom surface of the bottom plate, and the lower wing plate is fixed by welding after being attached to the bottom surface of the reinforcing groove; the reinforcing longitudinal beam has the advantages of light weight, high strength and large welding area, and is used for improving the strength of the reinforcing groove and preventing the problem that cracks are easy to appear at the groove corner;
as shown in fig. 2, 3 and 4, the left and right overturn auxiliary frames have the same structure, are composed of longitudinal channel steel and transverse channel steel which are welded with each other, and have the advantages of light weight and high strength; the left overturning auxiliary frame and the right overturning auxiliary frame are used for connecting a lifting oil cylinder;
