More importantly, the semitrailer can also play a certain promoting role in the organization form of logistics in China.
The semitrailer in the prior art has the disadvantages that the self weight is large and the increase of cargo transportation weight is not facilitated due to the structure of the accessories.
Referring to the attached drawing 1, the reinforcing structure for the cross beam of the semi-trailer compartment body in the prior art generally comprises a reinforcing plate (2), wherein three edges of the reinforcing plate (2) are fixed with a longitudinal beam (3), a cross beam (4) and a compartment bottom plate (5) into a whole respectively, the reinforcing plate body needs thick materials for achieving design strength, and meanwhile, the cross beam and the compartment bottom plate need thick materials for processing, so that enough strength is guaranteed, and the weight is large and the performance is unstable.
SUMMERY OF THE UTILITY MODEL
Aiming at the defects in the prior art, the utility model provides the reinforcing structure for the semitrailer compartment body beam, which reduces the dead weight, improves the connection strength and has stable performance.
In order to solve the technical problems, the utility model adopts the following technical scheme:
a semitrailer carriage body additional strengthening for crossbeam, wherein: the connecting support plate is rectangular, a reinforcing plate integrated with the connecting support plate is fixed on the side wall a of the connecting support plate, and the reinforcing plate is triangular;
when in use, the bevel edge a of the reinforcing plate is fixed on the top plate surface a of the longitudinal beam, or/and the bevel edge b of the reinforcing plate is fixed on the top plate surface of the cross beam; the side wall b of the connecting support plate is fixed on the top plate surface a of the longitudinal beam, or/and the side wall c of the connecting support plate is fixed on the top plate surface of the cross beam, or/and the side wall d of the connecting support plate is fixed on the bottom plate surface of the carriage bottom plate.
Due to the structure, the self weight is reduced, the connection strength is improved, and the performance is stable.

Detailed Description
In order that those skilled in the art can better understand the present invention, the following technical solutions are further described in conjunction with the accompanying drawings and examples:
referring to fig. 2 to 4, the semitrailer compartment body cross beam reinforcing structure, wherein: the connecting support plate comprises a connecting support plate 1, wherein the connecting support plate 1 is rectangular, a reinforcing plate 2 integrated with the connecting support plate 1 is fixed on a side wall a101 of the connecting support plate 1, and the reinforcing plate 2 is triangular;
when in use, the inclined edge a201 of the reinforcing plate 2 is fixed on the roof surface a301 of the longitudinal beam 3, or/and the inclined edge b202 of the reinforcing plate 2 is fixed on the roof surface 401 of the cross beam 4; the side wall b102 of the tie support plate 1 is fixed to the ceiling surface 301 of the side member 3, the side wall c103 of the tie support plate 1 is fixed to the ceiling surface 401 of the cross member 4, and the side wall d104 of the tie support plate 1 is fixed to the floor surface 501 of the floor panel 5. In the embodiment, the self weight is reduced, the connection strength is improved, and the performance is stable. The weight of the connecting support plate 1 and the reinforcing plate 2 together is about four fifths of that of the existing reinforcing structure for the semitrailer compartment body cross beam. When the semi-trailer carriage body cross beam reinforcing structure is used specifically, when the cross beam 4 adopts a channel steel structure, the two side walls of the cross beam 4 are respectively provided with a set of semi-trailer carriage body cross beam reinforcing structure in the scheme; correspondingly, the oblique side b202 of the reinforcing plate 2 is fixed on the side wall of the cross beam 4, and the side wall c103 of the connecting support plate 1 is fixed on the side wall of the cross beam 4.
