Abstract

The utility model discloses a kind of dump truck carriage floor, relate to field of automobile; Dump truck carriage floor comprises main longitudinal grider, longeron, edge sealing crossbeam, crossbeam and lower flat board, and wherein the shape of cross section of longeron is the inverted U of making by rolling drawing technique, and its opening is weldingly fixed on described lower flat board; The utility model can solve dump truck carriage floor longeron in prior art and make the problem time-consuming, productive costs is high, longeron intensity is not high.

Description

Dump truck carriage floor

Technical field

The utility model relates to field of automobile, especially a kind of dump truck carriage floor.

Background technology

As shown in Figure 1, dump truck carriage floor is generally by main longitudinal grider 2, longeron 1, edge sealing crossbeam 3, crossbeam 5 and lower dull and stereotyped 4 is welded, wherein the length of longeron 1 is between 5.6 meters ~ 9.6 meters, its cross sectional dimensions is that 160mm * 85mm * 3mm(is high * wide * thick), the height to width ratio of cross-sectional plane is more than 1.8, therefore, cannot adopt the method straight forming of flanging machine flanging or diel swaging, in order to make longeron height reach requirement and intensity reaches industry standard, longeron is generally to adopt two sections of steel plates by flanging machine, to be bent into after the shape of channel-section steel, make-up is welded mutually again, as shown in Figure 2, the dump truck carriage floor longeron of this structure is not only wasted steel, the deadweight of weightening finish vehicle body, and weld time is also longer, the labour intensity of operating personal is larger.

Summary of the invention

The purpose of this utility model is to provide a kind of dump truck carriage floor, and it can solve dump truck carriage floor longeron in prior art and make the problem time-consuming, productive costs is high and longeron intensity is not high.

In order to address the above problem, the technical solution adopted in the utility model is:

A dump truck carriage floor, comprises main longitudinal grider, longeron, edge sealing crossbeam, crossbeam and lower flat board, the inverted U of the shape of cross section of described longeron for forming by rolling drawing, and its opening is weldingly fixed on described lower flat board.

Further: the aspect ratio of the cross-sectional plane of described longeron is 1.5 ~ 2.

Owing to having adopted technique scheme, the utility model compared with prior art has following beneficial effect:

1, adopt the utility model, can greatly save rolled steel dosage, by 6 meters, calculate every and reduce by 33 kilograms of material costs, 4.5 yuan/kilogram of materials, every is fallen material cost 33 * 4.5=148.5 unit/platform; Can greatly reduce welding job amount, reduce simultaneously welding wire and and during Welder approximately 50 yuan, every chassis approximately saves 200 yuan of costs altogether;

2, the utility model, owing to adopting rolling drawing forming technology, has not only solved bending technique and cannot manufacture cross-sectional plane for the problem of high narrow U-shaped beam, and the longeron intensity ratio prior art of making adopts the longeron intensity that bending and forming obtains to improve 30%;

3, adopt the utility model, fusion length greatly reduces, and longeron deflection greatly reduces, and under longeron and bottom plate of dump truck, flat board is fitted more, and whole dump truck carriage floor is more attractive in appearance, and presentation quality improves greatly.

The specific embodiment

Below in conjunction with drawings and Examples, the utility model is further described: as Fig. 1, shown in Fig. 3,

A kind of dump truck carriage floor, by main longitudinal grider 2, longeron 1, edge sealing crossbeam 3, crossbeam 5 and lower dull and stereotyped 4 is welded, wherein the height of main longitudinal grider 2 and longeron 1 is all greater than crossbeam 5, crossbeam 5 is through longeron 1 and main longitudinal grider 2, and with longeron 1, main longitudinal grider 2 weld togethers, edge sealing crossbeam 3 and longeron 1, main longitudinal grider 2 weld togethers, main longitudinal grider 2, longeron 1, crossbeam 5 and edge sealing crossbeam 3 all with lower dull and stereotyped 4 weld togethers, the shape of cross section of longeron 1 is inverted U-shaped for what make by rolling drawing technique, its opening is weldingly fixed on lower dull and stereotyped 4, the aspect ratio of the cross-sectional plane of longeron 1 is 1.5 ~ 2.

Claims

1. a dump truck carriage floor, comprise main longitudinal grider (2), longeron (1), edge sealing crossbeam (3), crossbeam (5) and lower flat board (4), it is characterized in that: the inverted U of the shape of cross section of described longeron (1) for making by rolling drawing technique, its opening is weldingly fixed on described lower flat board (4).

2. dump truck carriage floor according to claim 1, is characterized in that: the height to width ratio of the cross-sectional plane of described longeron (1) is 1.5 ~ 2.
