The specific embodiment:
Below in conjunction with accompanying drawing the present invention is further specified:
Shown in accompanying drawing, a kind of revolution tray carriage is provided with vehicle frame 4, road wheel 8 and drawbar frame 3; The structure of vehicle frame 4, road wheel 8 and drawbar frame 3 is identical with prior art with annexation, and this does not give unnecessary details, and it is characterized in that vehicle frame 4 is provided with turning gear and driving device; Turning gear is made up of rotary support 1 and revolution tray rack 2, and the rotary support 1 among the present invention adopts swing bearing, and rotary support 1 upper periphery is provided with gear ring; Driving device is by worm screw 12, swing arm 5, friction wheel 6, oscillating axle 18, support 13, fixed mount 16, permanent seat 14, main driving wheel 19, driving band 17, form from power wheel 20, upper arm 11, underarm 15, pull bar 7, foot-driven lever 21, stretcher 9 and return pin 10, captives joint with vehicle frame 4 in rotary support 1 lower end, captives joint with revolution tray rack 2 in the upper end; The outside is meshed with worm screw 12 through the gear ring of rotary support 1 periphery, and worm screw 12 two ends are hinged through fixed mount 16 and vehicle frame 4 respectively, and worm screw 12 belows are provided with oscillating axle 18; Friction wheel 6 is separately fixed on the oscillating axle 18 with main driving wheel 19, and oscillating axle 18 is hinged through folding arm and permanent seat 14 on the vehicle frame 4, and the upper arm 11 of folding arm and underarm 15 are hinged through hinge; Friction wheel 6 one sides are provided with swing arm 5, and opposite side is provided with main driving wheel 19, and swing arm 5 is provided with long slot bore; Swing arm 5 one ends and worm screw 12 are hinged, the other end and oscillating axle 18 sliding block joints that pass long slot bore, and driving band 17 1 ends are connected with oscillating axle 18 through main driving wheel 19; The other end is through being fixed on being connected with worm screw 12 on the worm screw 12; Hinge between pull bar 7 one ends and the folding arm is hinged, and the other end and foot-driven lever 21 are hinged, and foot-driven lever 21 is hinged with the support 13 that is fixed on the vehicle frame 4; Foot-driven lever 21 front ends are provided with return pin 10; The rear end is provided with stretcher 9, so that stretcher 9 drives pull bar 7 swings, and through return pin 10 location.
