Abstract
The utility model provides a semitrailer bottom plate bearing structure, include two boundary beams, two longerons, connect two many crossbeams between the longeron, connect the longeron with a plurality of wings between the boundary beam prop and with longeron parallel arrangement's a plurality of parallels back shafts, each crossbeam and each wing prop top surface and have all seted up the parallels draw-in groove, parallels back shaft card is gone into in the parallels draw-in groove, the top surface of crossbeam the top surface of wing prop the top surface of longeron the top surface of boundary beam with the equal parallel and level setting of top surface of parallels back shaft. The semitrailer bottom plate supporting structure has the advantages of simple structure, good supporting effect, difficult deformation and long service life.
Description
Technical Field
The utility model relates to a semitrailer, specific theory has related to a semitrailer bottom plate bearing structure.
Background
At present, the conventional semitrailer with the base plate sizing block has the conventional structure that the base plate sizing block is paved above a through beam structure, the base plate is paved above the base plate sizing block, the contact area of the base plate and the sizing block is small, and the semitrailer is easy to deform under the condition of heavy goods pressure, so that the service performance and the service life of the whole semitrailer are influenced.
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 semitrailer bottom plate bearing structure of simple structure, excellent in support effect, non-deformable, long service life is provided.
In order to realize the purpose, the utility model discloses the technical scheme who adopts is: the utility model provides a semitrailer bottom plate bearing structure, includes two boundary beams, two longerons, connects two many crossbeams between the longeron, connect the longeron with a plurality of wings between the boundary beam prop and with longeron parallel arrangement's a plurality of parallels back shaft, each crossbeam and each wing prop the top surface and have all seted up the parallels draw-in groove, parallels back shaft card is gone into in the parallels draw-in groove, the top surface of crossbeam the top surface that the wing propped the top surface of longeron the top surface of boundary beam with the equal parallel and level setting of top surface of parallels back shaft.
Based on the above, sizing block back shaft cross section is the rectangle, sizing block back shaft's cross section four angles are the fillet.
Based on the above, the cross sections of the sizing block support shaft are the same.
Based on the above, each crossbeam and each wing prop and all seted up a plurality of lightening holes.
Based on the above, two sizing block support shafts are respectively arranged between the edge beam and the adjacent longitudinal beam and between the two longitudinal beams.
The utility model discloses relative prior art has substantive characteristics and progress, specific theory, the utility model discloses a crossbeam with the wing props the top surface and sets up the parallels draw-in groove will the parallels back shaft is accomodate completely and is gone into wherein, promotes the crossbeam with the top surface of wing props with the boundary beam with longeron top surface parallel and level, and all with parallels back shaft top surface parallel and level, the atress of dispersion bottom plate, non-deformable when making the bottom plate bear the weight of the heavy object, life is longer, and it has simple structure, supports effectual, non-deformable, long service life's advantage.
Furthermore, the cross section of the sizing block support shaft is rectangular, the sizing block support shaft can be installed without dividing the upper part and the lower part, and the four corners are all provided with round corners, so that the alignment is convenient; the arrangement of the lightening holes reduces the dead weight of the frame; six parallels back shaft evenly distributed makes the bottom plate each department atress more even.
Drawings
Fig. 1 is the structural schematic diagram of the bottom plate supporting structure of the middle semitrailer of the utility model.
In the figure: 1. a boundary beam; 2. a stringer; 3. a cross beam; 4. a wing support; 5. a sizing block supporting shaft; 6. a sizing block clamping groove; 7. and (7) lightening holes.
Detailed Description
The technical solution of the present invention will be described in further detail through the following embodiments.
As shown in fig. 1, the semitrailer chassis supporting structure comprises two boundary beams 1, two longitudinal beams 2, a plurality of cross beams 3 connected between the two longitudinal beams 2, and a plurality of wing supports 4 connected between the longitudinal beams 2 and the boundary beams 1, and is a common device for frames in the field, and does not need creative labor.
In order to improve the supporting effect, this semitrailer bottom plate bearing structure still include with 6 paralleling arrangement's of longeron 6 paralleling back shaft 5, paralleling draw-in groove 6 has all been seted up with 4 top surfaces of each wing brace to each crossbeam 3, paralleling back shaft 5 card is gone into in the paralleling draw-in groove 6, be provided with two paralleling back shafts 5 between boundary beam 1 and the adjacent longeron 2 respectively, the top surface of crossbeam 3 the top surface of wing brace 4 the top surface of longeron 2 the top surface of boundary beam 1 with the equal parallel and level setting of top surface of paralleling back shaft 5.
When the vehicle bottom frame is used specifically, the bottom plate is laid on the upper surface of the vehicle bottom frame, and the top surface of the vehicle bottom frame is parallel and level, so that the bottom plate can be supported by supporting force from all places, pressure is dispersed, the supporting effect is improved, and the service life is not easy to deform and prolonged.
For the convenience of installation, sizing block back shaft 5 cross section is the rectangle, four angles of cross section of sizing block back shaft 5 are the fillet, the cross section of each department of sizing block back shaft 5 is the same, can not divide from top to bottom during the installation, and the four corners all sets up to the fillet, convenient counterpoint.
In order to reduce the overall weight of the frame, a plurality of lightening holes 7 are formed in each cross beam 3 and each wing brace 4.
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.
