The utility model is compared with the semi-trailer support base of prior art, and its beneficial effect is:
Heavier-duty supporting leg of the present utility model is good looking appearance not only, firm practicality, and the utility model is formed for connecting the base plate riser of slide plate by the cutting of base plate middle part and for the extension spring riser of stable equilibrium spring, and can save existing base riser, thereby alleviate than existing earth plate total quality.Balance spring is by slide plate and base plate tension, and three adapter shafts firmly are connected to an integral body by two slide plates, and two slide plates are synchronously rotated relative to base plate, are suitable for the road surface of different gradient.
The accompanying drawing explanation
Fig. 1 is existing supporting leg and understructure schematic diagram thereof.
Fig. 2 is leg structural base schematic diagram in existing supporting leg.
The structural representation that Fig. 3 is the utility model heavier-duty supporting leg.
Another visual angle angle schematic diagram that Fig. 4 is the utility model heavier-duty supporting leg.
The specific embodiment
Below pass through the specific embodiment, and the utility model is described in further detail by reference to the accompanying drawings.
As shown in Figure 1 and Figure 2, existing supporting leg comprises interior leg 2, outer leg 3, base 1.Wherein, outer leg 3 is enclosed within outside interior leg 2, interior leg 2 lower ends arrange base 1, and the interior up-and-down movement of leg 3 outside, be provided with outside jacking system that be connected with interior leg 2, that the interior leg of control pumps in leg 3, this jacking system is included in the inner intermeshing driving and driven gear of outer leg 3, connects the screw mandrel of driven gear, and the supporting leg nut matched with screw mandrel.The bottom reducing of interior leg 2 and central siphon 21 welding, central siphon 21 and base 1 pivot joint, the bottom closing-in structure of interior leg 2 is fixed on base 1 by central siphon 21.Supporting leg operates the internal gear transmission device by crank, makes supporting leg be increased or descends.
Shown in Fig. 3, Fig. 4, the base of heavier-duty supporting leg of the present utility model comprises base plate 5, pair of slide 6, datum axle 7, a pair of balance spring 8, wherein, the middle part punching of base plate 5 forms four rim charges, four rim charges upwards draw, and form the base plate riser 51 of a pair of symmetry and the extension spring riser 52 of a pair of symmetry, and base plate riser 51 profiles are trapezoidal, extension spring riser 52 profiles are triangle, and both are by the middle part plate cutting gained of base plate 5.Slide plate 6 is for roughly fan-shaped, and radian, between 120 degree to 150 degree, is established the strengthening groove 63 at a plurality of sensings center on the plate face of slide plate 6.Two slide plates 6 are erected at respectively the outside of base plate riser 51, and base plate riser 51 straight up, is provided with the fastening degree that clamping washer is connected to strengthen both between base plate riser 51 and slide plate 6.Be provided with three through holes on the plate face of two slide plates 6, be separately positioned on both sides, top and the bottom center of plate face, distribute along radial lines such as fan-shaped slide plates.Adapter shaft 9 interspersed in through hole firmly is connected to one by two slide plates 6.Adapter shaft 9 can be to be welded and fixed or to fix with nut with the mode that is connected and fixed of slide plate 6.On base plate riser 51, the interspersed position of corresponding adapter shaft 9 is provided with and dodges via hole, and adapter shaft 9 is dodged the through hole of via hole and slide plate 6 through this.
