Specific embodiment
In order that technological means, creation characteristic, reached purpose and effect that the utility model is realized are easy to understand, under
Face combines and is specifically illustrating, and the utility model is expanded on further.
As shown in Figures 1 to 4, the utility model provides a kind of eccentric work piece and overturns car, for loading the open circuit of L-type locomotive
Device, including underframe 1, are separately positioned on the support at the symmetrical two ends of the underframe 1, also include passing through 5 turns of rotating shaft with two supports
Dynamic connection and the pivoted frame 2 between described two supports, and the pivoted frame 2 is adjustable support, wherein, the rotating shaft 5 is extremely
A few end is provided with damping cam 3；Also include arranging on the bracket and for providing rotation to the damping cam 3
The elastic device of resistance；
Also include：The turbine gearbox being connected is rotated with the rotating shaft 5, what is be connected with the turbine gearbox turns manually
Wheel.
Wherein as shown in Fig. 2 pivoted frame 2 includes：Rectangular frame, and be slidedly assemblied in the rectangular frame and can be with
At least two support beams 4 of setting position are locked onto, in each support beam 4 long waist shaped installing hole is provided with.Specifically, the square
Long waist shaped hole is provided with shape framework, the support beam 4 is by being located in the bolt in the long waist shaped hole and the rectangle
Framework connects.In the present embodiment, using in plate shaping, design increases movable support beam 4, it is possible to achieve multiple product group
Debug examination.When needing to support various sizes of product, realized to various sizes of product by adjusting the position of support beam 4
Assembling.
As shown in figure 4, the elastic device includes：Slidable fit press strip support plate 11 on the bracket, and compression
Spring 8, and the two ends of the compression spring 8 are pressed on respectively on the support and the press strip support plate 11.Specifically, described
Spring support 6 is provided with frame, through hole is provided with the spring support 6, also including the slide bar 9 being located in the through hole,
And one end of the slide bar 9 is fixedly connected by slide plate 10 with the press strip support plate 11, the spring 8 is sleeved on the slide bar 9
