Description
The technical field is as follows:
the invention relates to the technical field of bulk cargo transportation equipment, in particular to a dump semitrailer frame.
Background art:
the self-unloading semi-trailer is mainly used for transporting bulk cargo such as grain, ore, coal, steel and the like. The frame is a base body of the self-unloading semitrailer and mainly used for supporting and installing various assemblies and bearing various loads inside and outside the semitrailer, so that the frame has enough strength and rigidity. In addition, for the self-discharging semitrailer, the frame needs to have enough strength and rigidity, and the frame needs to be matched with a chain conveying mechanism, two discharging modes of the current semitrailer are mainly adopted, one mode is that an oil cylinder is adopted to lift the carriage for discharging, the other mode is that a special chain conveying mechanism for discharging is installed at the bottom of the carriage, and the chain conveying mechanism has the advantages of high safety, high discharging efficiency and the like.
As shown in fig. 12, the existing frame includes two longitudinal beams (also called as a girder), a plurality of cross beams are connected between the two longitudinal beams, each longitudinal beam is composed of an upper wing plate, a web plate and a lower wing plate, and although the existing frame structure meets the requirements of the dump semi-trailer to some extent, some disadvantages exist in practical use: firstly longeron structural strength is not enough, and current longeron adopts the structural design of approximate C type mostly, and this kind of structural design bears the load carrying capacity generally, and in addition the semitrailer automobile body is generally longer (automobile body length generally varies from several meters to ten meters), consequently, has the problem of taking place to warp when current longeron structure in-service use, seriously influences the security of whole car. The second is that joint strength between longeron and the crossbeam is not enough, and current crossbeam is connected with the longeron and mainly relies on the web welded connection of crossbeam terminal surface and longeron, relies on the welding realization of a face to connect promptly, and the ability that this kind of welded connection mode bears the load is relatively poor, opens because of assaulting very easily and welds, and the crossbeam breaks away from with the longeron when serious, produces the incident.
In order to improve the structural strength of the frame, make the product design more reasonable, and tend to be perfect, various attempts have been made in the prior art, and an attempt is made to make the overall structure of the frame more reasonable, but there are some parts that are not as desired, as shown in fig. 13 and 14, for example, in order to improve the structural strength of the longitudinal beam, the prior art mainly adopts a measure of welding a reinforcing plate outside the longitudinal beam along the length direction thereof, the reinforcing plate mainly connects and reinforces a web plate and a lower wing plate, the measure can improve the structural strength of the longitudinal beam, but brings disadvantages, for example, because the design of the reinforcing plate is added, a plurality of welding processes are additionally added, the welding of the long-strip longitudinal beam is time-consuming and labor-consuming, the welding difficulty is very large, the longitudinal beam is easy to deform due to welding in the welding process, and the deformation not only reduces the structural strength of the, the problem of leakage caused by untight adhesion and sealing of the longitudinal beam and a belt in the chain conveying mechanism can be caused, the longitudinal beam and the carriage can not be aligned when being welded, the welding difficulty is increased, and the connecting strength between the carriage and the longitudinal beam is reduced; if the reinforcing plate and the longitudinal beam are relatively closed, the interior of the reinforcing plate is difficult to perform anticorrosion treatment, and corrosive substances such as rainwater are easily reserved between the reinforcing plate and the longitudinal beam, so that the longitudinal beam can generate the problem of rusting and corrosion after being used for a period of time, and the structural strength is reduced.
In order to improve the connection strength between the cross beam and the longitudinal beam, in the prior art, a triangular base is welded on the longitudinal beam, then the cross beam is welded on the triangular base and the longitudinal beam, and further the connection strength between the cross beam and the longitudinal beam is improved.
Through the analysis, the structural strength of the frame is improved mainly by welding the reinforcing component in the prior art, the scheme is applicable to the components with short length and large thickness, but is inapplicable to the longitudinal beam with long strip shape and small thickness, the structural strength of the frame can be improved in the prior art, the technical effect is limited, time and labor are wasted due to the additionally added welding process, the longitudinal beam is deformed, and the structural strength of the longitudinal beam and the matching between the longitudinal beam and a carriage, a chain conveying mechanism and the like are further influenced.
