Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further described.
As shown in Figures 1 to 3, this combined mobile machinery chassis connection structure, comprises H frame 1 and longeron 2, and described H frame 1 is connected with longeron 2 by the perpendicular H frame connecting panel 4 be fixedly connected with, and H frame connecting panel 4 top and bottom are respectively equipped with multiple tapped bore
3 and unthreaded hole
5; Described longeron 2 comprises longeron upper connecting base 6 and longeron lower connecting base 9; The attachment face of described longeron upper connecting base 6 vertically arranges and is fixedly connected on the top of longeron 2, attachment face has and tapped bore
3 corresponding unthreaded holes
7; Described longeron lower connecting base 9 is fixedly connected on the lower position of longeron 2 medial surface, comprises connecting panel 13 and bracket 11 two parts, and the attachment face of connecting panel 13 and the attachment face of Connection Block 6 are positioned at same plane, and connecting panel 13 has and unthreaded hole
