Preferably, middle bench comprises the bench that more piece is rotatably connected successively, and the dismountable connection of more piece bench in the middle of said.
Preferably; Be connected through hinged seat between each bench; Each hinged seat comprises base, wherein connect on week of said base of first bench and middle bench to be formed with fitting face, the fitting face of said first bench can with said in the middle of bench fitting face each other against.
Preferably, each hinged seat also comprises the otic placode that is fixed on the said base, and the otic placode of each bench is rotatably connected through bearing pin.
Preferably, said bench can fold each other.
The utility model provides a kind of engineering machinery of using above-mentioned working stand.
Be formed with fitting face on the base of this first bench and middle bench hinged seat; When working stand used, the fitting face of the fitting face of this centre bench and this first bench leant, the bench and the first bench relative fixed in the middle of making; Therefore, working stand is comparatively stable in use.In addition, the middle bench that different length could dismantled or change to middle more piece bench each other to be changing the length of this working stand, thereby makes the tilt adjustable of the relative bottom surface of final section bench whole to proper angle, so that operating personnel's climbing.And this first bench is connected on the support of this project machinery, therefore is difficult for losing.

The specific embodiment
To combine the Fig. 1 to Fig. 5 in the utility model preferred embodiment below, the technical scheme among the utility model embodiment will be carried out clear, intactly description.
See also Fig. 1 and Fig. 2, the utility model provides a kind of working stand, and it is applied in the engineering machinery such as crane.This working stand comprises first bench 1, second bench 2, the 3rd bench 3 and the hinged seat 4 that first bench 1, second bench 2, the 3rd bench 3 are connected.
This first bench 1 is connected on the vehicle frame 6 of this project machinery through axis of rotation 5.This first bench 1 can this axis of rotation 5 for the center is rotated, so that this working stand is adjusted to preferable operating position.After this working stand is folding, rotate this first bench 1 again, this working stand is rotated to the appropriate location of vehicle frame 6, so that engineering machinery is carried out work.
Please combine to consult Fig. 4, this hinged seat 4 is fixed in this first bench 1 away from an end that is provided with this axis of rotation 5.This hinged seat 4 comprises base 41 and is fixed on the otic placode 42 on this base 41.This base 41 is rectangular, is formed with fitting face 410 on its week, offers a pin-and-hole (figure is mark not) on this otic placode 42.This base 41 is fixed on an end of this first bench 1.
The two ends of this second bench 2 respectively with base 41 Joints of this hinged seat 4.The otic placode 42 of these second bench, 2 one ends is hinged through bearing pin 7 with the otic placode 42 of this first bench 1.Therefore, this first bench 1 can be connected together with this second bench 2 each other rotatably.When the fitting face 410 of the base that is fixed in first bench 1 41 offseted with the fitting face 410 that is fixed in the base 41 of second bench 2, therefore this first bench 1 and these second bench, 2 relative fixed can improve the stability that this working stand uses.
This working stand is positioned on the vehicle frame 6 of engineering machinery through folding.When using, rotate this second bench 2 and the 3rd bench 3 so that this working stand is opened.When the fitting face 410 of the fitting face 410 of the base 41 of this second bench 2 and this first bench, 1 base 41 offsets, this second bench 2 and this first bench, 1 relative fixed.Then, the 3rd bench 3 is rotated with respect to this second bench 2, to adjust the angle between the 3rd bench 3 and the bottom surface 8, so that the 3rd bench 3 is fixed in preferable operating angle.When operating personnel climb last the 3rd bench 3; The 3rd bench 3 direction to bottom surface 8 under the effect of operating personnel's gravity spurs this second bench 2; Make this second bench 2 base 41 fitting face 410 and this first bench, 1 base 41 fitting face 410 tightly against, thereby increased the stability of this working stand.
See also Fig. 4, be appreciated that this working stand not only comprises said three-section ladder section, it can increase bench under the operating mode according to reality, so that operating personnel's climbing.Wherein, and the bench between first bench 1 and the final section bench can be considered in the middle of bench, this centre bench comprises the bench that more piece is rotatably connected successively.And middle more piece bench can be dismantled each other, therefore, can change the length of this working stand, thereby the angle of inclination of the relative bottom surface 8 of final section bench can be adjusted relatively, so that operating personnel's climbing.See also Fig. 5, this working stand can also fold, so that the engineering machinery structure is compact more.
Be appreciated that since first bench 1 and second bench 2 need to keep each other tightly against state, and other joint bench need not to keep above-mentioned state, therefore, other bases that save bench need not to be provided with fitting face.
Be formed with fitting face 410 on the base 41 of this first bench 1 and second bench, 2 hinged seats 4; When working stand uses; The fitting face 410 of this second bench 2 leans with the fitting face 410 of this first bench 1; Make second bench 2 and first bench, 1 relative fixed, therefore, working stand is comparatively stable in use.In addition, the middle bench that different length could dismantled or change to middle more piece bench each other to be changing the length of this working stand, thereby the angle of inclination of the relative bottom surface 8 of final section bench can be adjusted relatively, so that operating personnel's climbing.And this working stand is collapsible, therefore, can save its occupation space when taking in, and makes that the structure of engineering machinery is compact more.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
