Fig. 5 to 7 has longeron each decomposition unit separation structure figure of the casing of the superimposed trailer of high-low plate for the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in detail.
Refer to shown in Fig. 1 to Fig. 3, the casing that the present invention has the superimposed trailer of high-low plate comprises longeron 1, crossbeam 2, next stop post 3, middle station post 4, rear station post 5, side screen 6, rear screen 7, buckle 8 and supporting leg 9.
Described crossbeam 2 penetrates longeron 1, and be welded into an entirety, form the vehicle frame of superimposed trailer, the front end of described longeron 1 is gooseneck shape, rear end is flat, crossbeam 2 place be connected with described longeron 1 front end is provided with brace panel (not shown), play strengthen casing front end bear the effect of pressure.
Refer to Fig. 4 to 7, in the present invention, described longeron 1 comprises upper flange 12, lower wing plate 14 and reinforced plate 16.The rear end lower of described upper flange 12 and the upper front end weld together of lower wing plate 14, the lower left side of position of weld forms a level and smooth arc, the upper surface of described upper flange 12 and lower wing plate 14 is all smooth, and therefore, the upper right side of position of weld forms the stepped appearance of bottom right, a upper left.Described reinforced plate 16 is welded on the middle part of lower wing plate 14, plays the effect of reinforcing.
The structure of described casing both sides is the same.Described next stop post 3 and rear station post 5 are welded on the front and back end of longeron 1 respectively straight up, and described middle station post 4, between next stop post 3 and rear station post 5, is also welded on longeron 1 straight up, and in the present embodiment, this casing comprises in 4 post 4 of standing.Between next stop post 3 and adjacent middle station post 4, between rear station post 5 and adjacent middle station post 4 and between adjacent middle station post 4, one block of side screen 6 is respectively set, the base pivotable of described side screen 6 is connected on longeron 1, and described side screen 6 forms the side plate of casing together with next stop post 3, middle station post 4, rear station post 5.The equal pivotable in both sides of every block side screen 6 is provided with locating plate 62, described locating plate 62 offers draw-in groove (figure does not indicate), the position described next stop post 3, middle station post 4, rear station post 5 corresponding to the draw-in groove of described side screen 6 is provided with buckle 8, buckle 8 is for protruding from the column shape of station post, when on described locating plate 62 to be stuck in station post buckle 8 by draw-in groove, side screen 6 is closed, when beaing locating plate 62, when locating plate 62 is come off from buckle 8, then side screen 6 is opened.
Further, in order to open conveniently, described locating plate 62 blocks buckle 8 from bottom.
Described every block side screen 6 and rear screen 7 are solid breast board.
A sleeve pipe 74 is welded at the breast board place of described rear screen 7, and described sleeve pipe 74 has pin-and-hole, and described rear station post 5 is to being welded with bearing pin 52 in sleeve pipe 74 place, and described bearing pin 52 is inserted in the pin-and-hole of described sleeve pipe 74, and after ensureing further, the closedown of screen 7 is firm.
Described supporting leg 9 is arranged on the front end of vehicle frame, is positioned at the below of upper flange 12 and lower wing plate 14 weld, when casing do not connected headstock start to enable time, be used for supporting whole casing, when the casing of this superimposed trailer starts to enable, in connection during headstock, then supporting leg 9 can be accepted.
The side, elongatedness direction, bottom of described longeron 1 is provided with 20 boomers, and casing both sides arrange 40 boomers altogether.
Because the upper plane of upper flange 12 is higher than the upper plane of lower wing plate 14, and all side screens 6 are consistent with the height of rear screen 7, therefore, the whole height being positioned at the side screen 6 above upper flange 12 is lower than the height of side screen 6 of top being positioned at lower wing plate 14, namely actually reduce the height of whole vehicle frame, increase the height of the side screen 6 of the top of lower wing plate 14, this structure, make the overall decentralization of superimposed trailer, enhance the weight capacity of superimposed trailer, decentralization also ensure that safety in vehicle transportation process.
Above by reference to the accompanying drawings to invention has been exemplary description; obvious specific implementation of the present invention is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present invention is conceived and technical scheme is carried out; or design of the present invention and technical scheme directly applied to other occasion, all within protection scope of the present invention without to improve.
