In order to solve the above problems, people are always seeking an ideal technical solution.
Disclosure of Invention
The utility model aims at the not enough of prior art to a sideboard formula self-discharging semitrailer frame that whole light in weight, goods carry the face and reduce, the focus is stable is provided.
In order to realize the purpose, the utility model discloses the technical scheme who adopts is: the utility model provides a breast board formula self-discharging semitrailer frame, includes frame and last frame down, the frame includes crossbeam and longeron down, and the longeron is the I-beam, and the crossbeam outer end still is equipped with the bracing of connecting the longeron bottom, it includes the through-type crossbeam of a plurality of parallels to go up the frame, the through-type crossbeam supports on the last bearing surface of the longeron of frame down, has got rid of the longeron structure of last frame, makes the through-type crossbeam directly support on the last bearing surface of frame longeron down, has alleviateed the weight of whole car, has reduced the height of cargo plane.
Basically, the through type cross beam is a straight beam and is suitable for a semi-trailer with light load.
Basically, the through-type cross beam is a cross beam with a plurality of downward bending structures, the bending structures of the through-type cross beam are connected with the upper supporting surface of the longitudinal beam of the lower frame, the bending resistance of the through-type cross beam is improved due to the bending structures, the stability is higher, and more pressure, vibration or jolt can be resisted.
Basically, the bending structure is integrally in a flaring U shape.
Basically, the lower surface of the bending structure is a plane.
Basically, the bottom plate sizing block is installed at the sunken position of the bending structure, the upper end face of the bottom plate sizing block is flush with the upper surface of the through type cross beam, the supporting area of the cargo carrying bottom plate is increased, and the local deformation of the cargo carrying bottom plate is avoided.
The utility model discloses relative prior art has substantive characteristics and progress, specific theory, the utility model discloses get rid of the longeron structure of frame, adopt through-type crossbeam to support on the last holding surface of the longeron of lower carriage, reduced the weight of two longerons on the one hand, on the other hand carries the center of cargo surface lower, and vehicle-mounted stability is higher, and it has whole light in weight, the goods carries the advantage that the face reduces, the focus is stable.

In the figure: 1. a stringer; 2. a cross beam; 3. a cross beam; 4. a stringer; 4-1, an upper supporting surface; 5. bracing; 6. a through-type cross beam; 7. a bending structure; 8. and a bottom plate sizing block.
Detailed Description
The technical solution of the present invention will be described in further detail through the following embodiments.
Example 1
As shown in fig. 2, a breast board formula self-discharging semitrailer frame, includes frame and last frame down, the frame includes crossbeam 3 and longeron 4 down, and longeron 4 is the I-beam, and 3 outer ends of crossbeam still are equipped with the bracing 5 of connecting 4 bottoms of longeron, it includes through crossbeam 6 of a plurality of parallels to go up the frame, through crossbeam 6 is straight beam, and this straight beam structure can be the linear type section bar that has stable structure such as square pipe, through crossbeam 6 supports on the last holding surface 4-1 of longeron 4 of frame down.
In the embodiment, the longitudinal beam structure of the upper frame is removed, so that the through-type cross beam 6 is directly supported on the upper supporting surface 4-1 of the longitudinal beam 4 of the lower frame, the cargo carrying surface can be effectively supported, the longitudinal beam of the upper frame is saved, and the weight is lighter; furthermore, the number of the parts on the shelf is greatly reduced, thereby being beneficial to standardized operation; the upper frame has no longitudinal beam structure, so that the total height of the upper frame is reduced, the loading surface is reduced, and the center of gravity is more stable.
Example 2
As shown in fig. 3 and 4, the through-type cross beam 6 is a cross beam with a plurality of downward bending structures 7, for example, 3 is a cross beam with 2 bending structures 7, fig. 4 is a cross beam with 5 bending structures 7, the bending structures 7 of the through-type cross beam 6 are connected with the upper supporting surface 4-1 of the longitudinal beam 4 of the lower frame, the bending structure improves the bending resistance of the through-type cross beam 6, the stability is higher, the through-type cross beam can resist more pressure, vibration or bump, the bending structures 7 are integrally in a flaring U shape, and the lower surface of the bending structures 7 is a plane, so that the contact with the longitudinal beam 4 is more stable.
The bottom plate sizing block 8 is installed at the sunken position of the bending structure 7, the upper end face of the bottom plate sizing block 8 is flush with the upper surface of the through type cross beam 6, the supporting area of the cargo carrying bottom plate is increased, and the local deformation of the cargo carrying bottom plate is avoided.
Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting the same; although the present invention has been described in detail with reference to preferred embodiments, it should be understood by those skilled in the art that: the invention can be modified or equivalent substituted for some technical features; without departing from the spirit of the present invention, it should be understood that the scope of the claims is intended to cover all such modifications and variations.
