Summary of the invention
For above-mentioned prior art Problems existing, the utility model provides a kind of engineering machinery chassis connection structure, and its carrying evenly, not easily occurs that stress is concentrated, and the structural strength of connection structure is large, and reliability is high.
To achieve these goals, a kind of engineering machinery chassis connection structure of the utility model, comprise H frame and longeron, described H frame comprises the horizontal connecting panel of H frame and connecting panel indulged by H frame, and the horizontal connecting panel of described H frame is indulged connecting panel with H frame and is connected; Described longeron comprises the horizontal connecting panel of longeron and longeron indulges connecting panel, and the horizontal connecting panel of described longeron is indulged connecting panel with longeron and is connected; The horizontal connecting panel of described H frame and H frame are indulged connecting portion that the connecting portion of connecting panel and the horizontal connecting panel of longeron and longeron indulge connecting panel and are coordinated and assemble, and H frame is fixedly connected with between longeron.
Preferably, the horizontal connecting panel of described H frame and H frame indulge that connecting panel is vertical to be connected, and the horizontal connecting panel of described longeron and longeron indulge that connecting panel is vertical to be connected.
Preferably, connecting panel vertical welding indulged by the horizontal connecting panel of described H frame and H frame, and the horizontal connecting panel of described longeron and longeron indulge connecting panel vertical welding.
Preferably, the vertical joints position of connecting panel indulged by the horizontal connecting panel of described H frame and H frame and the horizontal connecting panel of longeron coordinates with the vertical joints position that longeron indulges connecting panel, between the horizontal connecting panel of described H frame and the horizontal connecting panel of longeron and H frame indulge connecting panel and longeron and indulge between connecting panel and be all bolted.
Preferably, the horizontal connecting panel of described H frame and H frame are indulged on connecting panel and are all had unthreaded hole, and the relevant position that the horizontal connecting panel of described longeron and longeron indulge connecting panel all has tapped bore, and bolt screws in side from top respectively and is connected H frame and longeron.
Compared with prior art, H frame in the utility model and longeron are by horizontal connecting panel and vertical connecting panel composition, and from end face and side both direction realization connection between the two, its three-dimensional connection structure carrying evenly, not easily occur that stress is concentrated, the structural strength of connection structure strengthens greatly, and connection reliability is high; This structure under the prerequisite ensureing chassis bottom-to-top-height, can provide enough structure spaces to H frame, to ensure that H frame has enough structural strengths simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, the horizontal connecting panel of H frame, 2, bolt, 3, the horizontal connecting panel of longeron, 4, H frame indulges connecting panel, 5, longeron indulges connecting panel, 6, H frame, 7, longeron.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, the utility model engineering machinery chassis connection structure, comprises H frame 6 and longeron 7, and described H frame 6 comprises the horizontal connecting panel 1 of H frame and connecting panel 4 indulged by H frame, and the horizontal connecting panel 1 of described H frame is indulged connecting panel 4 with H frame and is connected; Described longeron 7 comprises the horizontal connecting panel 3 of longeron and longeron indulges connecting panel 5, and the horizontal connecting panel 3 of described longeron is indulged connecting panel 5 with longeron and is connected; The horizontal connecting panel of described H frame 1 and H frame are indulged connecting portion that the connecting portion of connecting panel 4 and the horizontal connecting panel 3 of longeron and longeron indulge connecting panel 5 and are coordinated and assemble, and are fixedly connected with between H frame 6 with longeron 7.
During work, because the connection of H frame 6 with longeron 7 is made up of end face and side, evenly, not easily occur that stress is concentrated, the structural strength of connection structure strengthens greatly, and connection reliability is high in three-dimensional connection structure carrying.This structure under the prerequisite ensureing chassis bottom-to-top-height, can provide enough structure spaces to H frame 6, to ensure that H frame 6 has enough structural strengths simultaneously.
