Abstract
The present invention discloses a kind of generous amount concrete mixing and transporting car subframe, mainly solves significantly increasing of trucd mixer load, and subframe is the problem of fracture easily. Its structure comprises auxiliary girder, foreground, backstage, cable-stayed support, U-shaped bent plate and diagonal brace, described foregrounding one end above auxiliary girder, described backstage is arranged on the other end of auxiliary girder top, described U-shaped bent plate is arranged on auxiliary girder, between U-bend plate and backstage, be provided with cable-stayed support, between the auxiliary girder stull of backstage bottom front and U-shaped bent plate, be provided with diagonal brace. This subframe can be good at improving the subframe intensity of concrete mixing and transporting car, meet the applying working condition of concrete mixing and transporting car under generous amount operating mode completely, improve the local bending-twisting performance of auxiliary frame of mixer truck, fully optimized the stressing conditions of subframe.
Description
Technical field
The present invention relates to a kind of subframe, specifically a kind of generous amount concrete mixing and transporting car subframe.
Background technology
At present, domestic commerce Concrete Industry continues burning hot, measures also increasingly as the side of the trucd mixer of the requisite ring of concrete transportation, and the load of trucd mixer is also increasing. Therefore, trucd mixer is also more and more higher to the requirement of strength of subframe, strengthen the intensity of whole subframe and the concrete mixer truck manufacturer of most domestic just strengthens material used on original architecture basics, but this kind of method can not well be dealt with problems. Due to significantly increasing of trucd mixer load, the easy fracture location of subframe is mainly cable-stayed support front end and position, rear end, foreground, and this not only has a strong impact on the use safety of trucd mixer, and has greatly increased user's maintenance cost.
Summary of the invention
The object of the present invention is to provide a kind of generous amount concrete mixing and transporting car subframe, mainly solve significantly increasing of trucd mixer load, subframe is the problem of fracture easily. This subframe can be good at improving the subframe intensity of concrete mixing and transporting car, meet the applying working condition of concrete mixing and transporting car under generous amount operating mode completely, improve the local bending-twisting performance of auxiliary frame of mixer truck, fully optimized the stressing conditions of subframe.
The present invention solves the technical scheme that its technical problem takes: a kind of generous amount concrete mixing and transporting car subframe, its structure comprises auxiliary girder, foreground, backstage, cable-stayed support, U-shaped bent plate and diagonal brace, described foregrounding one end above auxiliary girder, described backstage is arranged on the other end of auxiliary girder top, described U-shaped bent plate is arranged on auxiliary girder, between U-bend plate and backstage, be provided with cable-stayed support, between the auxiliary girder stull of backstage bottom front and U-shaped bent plate, be provided with diagonal brace.
Described U-shaped bent plate tips upside down in the square tube of auxiliary girder, and flexibly connects with longeron.
Described cable-stayed support one end and backstage welding, the other end and the welding of U-shaped bent plate.
Auxiliary girder stull welding under described diagonal brace one end and backstage, the other end and U-shaped bent plate are buckled in the inner side welding of auxiliary girder square tube.
The invention has the beneficial effects as follows:
1, the heavy load that the structure of this auxiliary frame of mixer truck has solved generous amount trucd mixer brings frame to snap problem, and the stress of having avoided welding to cause is concentrated, and has improved the local bending-twisting performance of auxiliary frame of mixer truck, has fully optimized the stressing conditions of subframe.
2, owing to increasing the U-shaped bent plate of a transition between cable-stayed support and longeron, the welding of cable-stayed support and U-shaped bent plate, U-shaped bent plate and longeron do not weld and adopt and flexibly connect, and have avoided welding the problem of stress concentration causing.
3, owing to increasing " people " font diagonal brace between the auxiliary girder in front side, backstage, both can improve the bending-twisting performance in this region, can play the effect of front and back, location to U-shaped bent plate again.
Brief description of the drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is the top view of Fig. 1;
Fig. 3 is the A-A cutaway view of Fig. 2.
In figure: 1 auxiliary girder, 2 foregrounds, 3 backstages, 4 cable-stayed supports, 5U type bent plate, 6 diagonal braces, 7U type bolt, 8 chassis of mixer trucks.
Detailed description of the invention
With reference to Figure of description, the generous amount concrete mixing and transporting car of one of the present invention subframe is described in detail below.
As shown in Figure 1, Figure 2, Figure 3 shows, the generous amount concrete mixing and transporting car of one of the present invention subframe, its structure comprises auxiliary girder 1, foreground 2, backstage 3, cable-stayed support 4, U-shaped bent plate 5 and diagonal brace 6, described auxiliary girder 1 is positioned at the below of whole subframe, be placed on chassis of mixer truck 8, auxiliary girder 1 is main by connecting to form between two square tubes as skeleton and two square tubes; Described foreground 2 is arranged on one end of auxiliary girder 1 top, described backstage 3 is arranged on the other end of auxiliary girder 1 top, described U-shaped bent plate 5 is arranged on auxiliary girder, between U-bend plate and backstage, be provided with cable-stayed support, between the auxiliary girder stull of backstage bottom front and U-shaped bent plate 5, be provided with " people " font diagonal brace 6.
The 3 times auxiliary girder stulls welding welding of described diagonal brace 6 one end and backstage, the other end and U-shaped bent plate 5 are buckled in the inner side welding of auxiliary girder square tube. Both can improve the bending-twisting performance in this region, can play the effect of front and back, location to U-shaped bent plate 5 again. U-bolt 7 respectively in 1 front and back, foreground, the position such as 3 front portions, backstage, central rack and U-shaped bent plate 5 is fixedly connected with whole frame with chassis of mixer truck 8, make whole frame stress equalization.
Described U-shaped bent plate 5 tips upside down in the square tube of auxiliary girder 1, and flexibly connects with longeron. U-shaped bent plate 5 does not weld with longeron and adopts and flexibly connect, the problem of stress concentration of having avoided welding to cause.
Weld on described cable-stayed support 4 one end and backstage 3, and the other end and U-shaped bent plate 5 weld.
The structure of auxiliary frame of mixer truck of the present invention has solved the heavy load of generous amount trucd mixer and has brought frame to snap problem, the stress of having avoided welding to cause is concentrated, improve the local bending-twisting performance of auxiliary frame of mixer truck, fully optimized the stressing conditions of subframe.
The above, principles more of the present invention just explain through diagrams, this description is not that in concrete structure and the scope of application described shown in the present invention will being confined to, therefore the corresponding modify being likely utilized every and equivalent, all belong to the scope of the claims that the present invention applies for.
Except technical characterictic described in description, all the other technical characterictics are those skilled in the art's known technology.
