The top of longeron is vertically arranged and be fixedly connected on, the unthreaded hole II corresponding with screwed hole I is provided with mounting surface;Described longeron
Lower connecting base is fixedly connected on the lower position in side rail inner face, including connecting plate and bracket two parts, the mounting surface of connecting plate
In being generally aligned in the same plane with the mounting surface of connecting seat, the screwed hole II being engaged with unthreaded hole I is provided with connecting plate, and unthreaded hole II is extremely
The vertical range of screwed hole II coordinates with the vertical range size of screwed hole I to unthreaded hole I;Bracket is fixedly connected on connecting plate,
And its cross section is L-shaped structure, the interior well width of L-shaped structure coordinates with the thickness of H frame connecting plates;Unthreaded hole I connects apart from H framves
The distance of fishplate bar bottom is with screwed hole II to the transverse slat upper surface of L-shaped structure apart from dimensional fits;Bolt connects through unthreaded hole II
Meet screwed hole I;Bolt passes through unthreaded hole I connection screw thread holes II.
L-shaped structure transverse slat end is provided with a baffle plate so that the cross section of bracket is in J-hook structure.
Connecting plate side is welded with guide pad, and described guide pad and the mating surface and vertical direction of H frame connecting plates is in 0-
90 degree of angles.
The lower end of H frame connecting plates is welded with contiguous block, and described contiguous block is pasted with the crotch upper surface of J-hook structure
Close, through hole is provided with inside it, open up through hole and be engaged with unthreaded hole I.
Diameters of the screwed hole I than screwed hole II is big.
Compared with existing equipment, this combined mobile machinery chassis attachment structure is vertically connected with seat with increased by H framves
Longeron fitted from side and assemble, the especially design of J-hook, the crotch of J-hook fitted with connecting bolt face together with hold
By the load on vertical direction so that whole attachment structure increases H frame vertical structure chis while chassis height is ensured
It is very little, so as to ensure that its structural strength;Guide pad, J-hook are more easy for the positioning of H framves.

Specific embodiment
The present invention is further described below in conjunction with the accompanying drawings.
As shown in Figures 1 to 3, this combined mobile machinery chassis attachment structure, including H frame 1 and longeron 2, described H framves 1
It is connected with longeron 2 by the perpendicular H framves connecting plate 4 being fixedly connected, the upper end of H framves connecting plate 4 is provided with multiple screwed hole I3, under
End is provided with multiple unthreaded hole I5;Described longeron 2 includes longeron upper connecting base 6 and longeron lower connecting base 9;Connected on described longeron
The mounting surface of seat 6 is vertically arranged and is fixedly connected on the top of longeron 2, and the unthreaded hole corresponding with screwed hole I3 is provided with mounting surface
II7;Described longeron lower connecting base 9 is fixedly connected on the lower position of the medial surface of longeron 2, including 11 liang of connecting plate 13 and bracket
Part, the mounting surface of connecting plate 13 and the mounting surface of connecting seat 6 are provided with and unthreaded hole I5 phases in being generally aligned in the same plane on connecting plate 13
The screwed hole II10 of cooperation, and vertical range and the screwed hole I3 to unthreaded hole I5 of unthreaded hole II7 to screwed hole II10 vertical range
Dimensional fits;Bracket 11 is fixedly connected on connecting plate 13, and its cross section is L-shaped structure, the interior well width and H of L-shaped structure
The thickness of frame connecting plate 4 coordinates;Distances and screwed hole II10 to L-shaped structure of the unthreaded hole I5 apart from the bottom of H framves connecting plate 4
Transverse slat upper surface apart from dimensional fits;Bolt passes through unthreaded hole II7 connection screw thread holes I3;Bolt passes through unthreaded hole I5 connection screw thread holes
II10。
L-shaped structure transverse slat end is provided with a baffle plate so that the cross section of bracket 11 is in J-hook structure, J-hook structure
Crotch at formed an inside groove, preferably H framves connecting plate 4 can be fixed in bracket 11.
The side of connecting plate 13 is welded with guide pad 8, described guide pad 8 and the mating surface of H framves connecting plate 4 and vertical direction
In 0-90 degree angles.
The lower end of H framves connecting plate 4 is welded with contiguous block 12, described contiguous block 12 and the crotch upper table of J-hook structure
Face is fitted, and such crotch just can together bear the load on vertical direction with contiguous block 12, and enhancing structure intensity is opened inside it
There is through hole, open up through hole and be engaged with unthreaded hole I5.
Diameters of the screwed hole I3 than screwed hole II10 is big, is so provided with the screwed hole few compared with upper end in the lower end of longeron 2, with logical
Cross use intensity grade bolt high and realize load intensity requirement, the purpose for the arrangement is that because when mounted, the lower end of longeron 2
Install difficult compared with upper end, therefore open up less screwed hole I3 to reduce bolt installment work difficulty.
