For a connecting rod combined dump truck, the conventional method is that the amplitude of an auxiliary frame is fixed, the amplitude of a longitudinal beam of a carriage bottom plate is increased by (40-50) mm, the structure is mostly as shown in fig. 1 and fig. 2, the longitudinal beam of an underframe is of a rectangular or groove-shaped structure, the auxiliary frame 1, the longitudinal beam of the bottom plate 2 and the carriage bottom plate 3 are overlapped together, and meanwhile, in order to limit the left and right shaking of the longitudinal beam of the carriage bottom, a limiting device 4 is usually welded on the part of the longitudinal beam of the auxiliary frame, and the defects that the limiting device is easy to deform after long time of local welding and cannot well play a limiting role are overcome. The increase in the height of the bed plate is to prevent the bed plate from interfering with the bed lifting mechanism.
Therefore, the bottom longitudinal beam structure of the existing dumper connecting rod combined type lifting structure needs to be improved.
Disclosure of Invention
The utility model provides a dumper carriage structure, aiming at the problem that the gravity center of a dumper carriage is high due to an existing connecting rod combined type lifting structure.
In order to solve the technical problems, the technical scheme of the utility model is as follows: the utility model provides a tipper carriage structure, includes from supreme superimposed sub vehicle frame, floor longitudinal and carriage bottom plate in proper order down, its characterized in that: the carriage bottom plate is provided with an inwards concave avoiding groove, a variable section part is arranged on the bottom plate longitudinal beam corresponding to the avoiding groove and used for supporting the inwards concave avoiding groove, a limiting baffle plate is arranged on the side surface of the bottom plate longitudinal beam, and the lower end of the limiting baffle plate can be in limiting fit with the auxiliary frame longitudinal beam.
In order to further limit the technical solution, the structure of the variable section part is as follows: the auxiliary longitudinal beam is fixed on the bottom plate longitudinal beam at the lower end, and the upper end of the auxiliary longitudinal beam is fixed in the avoidance groove.
Further limiting the technical scheme, the cross section of the variable section part is rectangular.
The technical scheme is further limited, the upper end of the limit baffle is fixed between the bottom plate longitudinal beam and the auxiliary longitudinal beam, the middle of the limit baffle is fixedly connected with the side face of the bottom plate longitudinal beam, and the lower end of the limit baffle extends to one side of the auxiliary frame longitudinal beam and is flanged outwards.
The technical scheme is further limited, and the floor longitudinal beam, the variable section part, the carriage floor and the limit baffle form a whole in a welding mode.
The utility model has the beneficial effects that: 1) the groove avoiding structure enables the carriage bottom plate to be in a structure with a high front part and a low back part, thereby effectively reducing the gravity center of the carriage and avoiding the problem that the carriage bottom plate interferes with the lifting mechanism; 2) the width and the longitudinal direction of the avoiding groove occupy extremely small volume of the cargo compartment, and the loading/unloading of the cargo is not influenced; 3) the limiting baffle is fixed on the longitudinal beam of the bottom plate, so that the limiting stability is improved; 4) the utility model improves the safety and stability, has strong practicability and is convenient to popularize and apply.

Detailed Description
As shown in fig. 3 and 4, the carriage structure of the dump truck comprises an auxiliary frame 1, a bottom plate longitudinal beam 2 and a carriage bottom plate 3 which are sequentially overlapped from bottom to top, wherein a concave avoiding groove 31 is formed in the carriage bottom plate, a variable section part 21 is arranged on the bottom plate longitudinal beam corresponding to the avoiding groove and used for bearing stress borne by the avoiding groove, the lower end of the variable section part is fixed on the bottom plate longitudinal beam, a limit baffle 5 is arranged on the side surface of the bottom plate longitudinal beam, and the lower end of the limit baffle can be in limit fit with the auxiliary frame longitudinal beam;
as shown in fig. 3 and 4, the structure of the variable cross section 21 is: the lower end of the auxiliary longitudinal beam is fixed on the bottom plate longitudinal beam, and the upper end of the auxiliary longitudinal beam is fixed in the avoidance groove; the structure is simple, the processing and the manufacturing are easy, and the existing resources can be fully utilized for modification;
as shown in fig. 3 and 4, the cross section of the variable section 21 is rectangular; the shape has the advantages of high strength and long service life;
as shown in fig. 3 and 4, the upper end 51 of the limit baffle 5 is fixed between the floor longitudinal beam and the auxiliary longitudinal beam, the middle part 52 of the limit baffle is fixedly connected with the side surface of the floor longitudinal beam, and the lower end 53 of the limit baffle extends to one side of the auxiliary longitudinal beam and is flanged outwards; the limiting baffle is fixed on the longitudinal beam of the bottom plate, so that the strength of the longitudinal beam of the bottom plate is improved; meanwhile, the problem that the limiting baffle is easy to deform when being fixed on the auxiliary frame is avoided;
as shown in fig. 3 and 4, the floor longitudinal beam 2, the variable cross section 21, the platform floor 3 and the limit baffle 5 are integrally formed by welding; the integral structure has the advantages of high strength, difficult deformation and long service life.
Description of the utility model assembly: as shown in fig. 3 and 4, the avoiding groove in the shape of an open groove is positioned at the front end of the carriage bottom plate, and a carriage front side plate is fixed at the front end of the carriage bottom plate; the bottom plate longitudinal beam, the limiting baffle plate and the auxiliary longitudinal beam which are sequentially overlapped from bottom to top are welded together; the front end of the bottom plate longitudinal beam is limited on the auxiliary frame through a limiting baffle, and the rear end of the bottom plate longitudinal beam is hinged with a turnover seat on the auxiliary frame; the bottom plate longitudinal beam is welded with the back of the carriage bottom plate, and the auxiliary longitudinal beam is welded in the avoidance groove; the avoiding groove is concave on the bottom surface of the carriage bottom plate and is convex in the carriage, so that the interference between a lifting mechanism for lifting the carriage and the carriage bottom plate can be avoided, and the gravity center of the carriage is reduced.
