Referring to lifting steering structure 200 under the transport trolley shown in Fig. 1 and Fig. 3, mainly comprise: rotate and be arranged on the lower support dish 9 on car body 2, be arranged on hydraulic fluid tank on described lower support dish 9 and control structure 17, vertical solution cylinder pressure 18, the apical support upper support dish 24 of described vertical solution cylinder pressure 18.Described lower support dish 9 is rotatably connected on and is fixed on the bolster 50 of car body 2 by connection bearing 49, the interior inner gear 48 that arranges of lower support dish 9, and the small machine 52 be fixed on car body 2 meshes by miniature gears 51 and inner gear 48.
Referring to steering structure 300 on the transport trolley shown in Fig. 1 and Fig. 4, mainly comprise: be fixed by a pin to the parallel connecting rod 23 on upper support dish 24, rotation is arranged on the micro hydraulic cylinder 60 on parallel connecting rod 23, described connector 59 rotates and is arranged on parallel connecting rod 23, and micro hydraulic cylinder guide rod 61 and the connector 59 of described micro hydraulic cylinder 60 are rotationally connected.
Referring to Fig. 5, described scissors stretching structure 400 mainly comprises: be arranged on the micro hydraulic cylinder 70 on connector 59, be arranged on the guide rod 68 on connector 59 by bracing frame 69, be arranged on the scissors bar linkage structure on guide rod 68, the micro hydraulic cylinder guide rod 71 of micro hydraulic cylinder 70 is connected to the connecting rod 67 on the scissors bar linkage structure.
Referring to Fig. 6, robot manipulator structure 500 mainly comprises: the manipulator be connected on the scissors bar linkage structure is placed plate 80, be fixed in manipulator and place the micro hydraulic cylinder 79 on plate 80, rotation is arranged at manipulator and places the mechanical paw 75 on plate 80, and connecting rod 76, an end of described connecting rod 76 is rotationally connected to micro hydraulic cylinder guide rod 78, the other end of micro hydraulic cylinder 79 and is rotationally connected to mechanical paw 75.
This transport trolley specific implementation process is as follows:
For example when object 20, during in the transport trolley left front, start power supply, motor 8 forwards, driving pulley 37 rotates, by belt 7 by transmission of power to driven pulley 6, driven pulley 6 and axletree 5 rotate, thereby drive driving wheel 4, rotate, and realize that car body integral body travels forward.In the proal process of transport trolley, linear electric motors 34 reversions, linear electric motors guide rod 35 shrinks, roller 15, in the interior slip of guide groove 14, makes pilot bar 13 around fixing hinge turning clockwise, drives Linkage steering 16 and moves right, steering shaft 11 is followed Linkage steering 16 and is rotated, and makes wheel flutter 13 left-handed turnings.When the close object of transport trolley, close the power supply of linear electric motors 34 and motor 8, the transport trolley stop motion.
Small machine 52 rotates along (contrary) hour hands, driving miniature gears 51 rotates along (contrary) hour hands, by miniature gears 51, with the inner gear 48 of lower support dish 9, be meshed, lower support dish 9 is rotated along (contrary) hour hands, by robot manipulator structure 500, after horizontal plane is adjusted to suitable position, small machine 52 stops operating.
Hydraulic Pump and control structure 17 are started working, and by adjusting the hydraulic oil volume in vertical solution cylinder pressure 18, make vertical solution cylinder pressure 18 flexible, drive rising and the decline of upper support dish 24, thereby have realized rising and the decline of robot manipulator structure 500 on perpendicular.
After the above-mentioned adjustment to robot manipulator structure 500 locus, micro hydraulic cylinder 79 is started working, 78 elongations of micro hydraulic cylinder guide rod, and mechanical paw 75 opens.Then, micro hydraulic cylinder 70 is started working, and 71 elongations of micro hydraulic cylinder guide rod, promote connecting rod 67 two ends slide blocks along guide rod 68 to front slide, and the scissors bar linkage structure is stretched, and makes robot manipulator structure 500 further close to object 20.
When object 20 enters mechanical paw 75, can capture in scope, micro hydraulic cylinder guide rod 78 shrinks, mechanical paw 75 is object promptly, micro hydraulic cylinder guide rod 71 shrinks, the scissors bar linkage structure draws in, Hydraulic Pump and control structure 17 make 18 elongations of vertical solution cylinder pressure, by gripping object 20, risen, after rising to compartment 1 upper limb height, small machine 52 rotates along (contrary) hour hands, and lower support dish 9 is rotated, 61 elongations of micro hydraulic cylinder guide rod, angle between parallel connecting rod 23 and scissors bar linkage structure is reduced, shorten object 20 and arrive the just top time of compartment 1.When object 20 arrive compartments 1 just above after, micro hydraulic cylinder guide rod 78 extends, mechanical paw 75 opens, object 20 falls into compartment, completes object and collects work.
Start power supply, linear electric motors 34 and motor 8 rotate, and whole car body continues as required motion and finds next target.
The Automatic Guided Vehicle that above embodiment proposes, a kind of as transport trolley, by controlling opening and tightening to catch different sizes and difform goods of mechanical paw 75, as goods, cylindric and cubic object and some fitfull article etc. of some fitfull mechanical component, packing moulding.In addition, this money Automatic Guided Vehicle can also be regulated by hydraulic actuating cylinder, scissor-like jack rising, decline, elongation and the contraction of robot manipulator structure, thereby can be transported to the article of different spatial, and be placed in compartment, realize that article carrying is to the full process automatization operation of depositing.
Although the utility model with preferred embodiment openly as above; but it is not for limiting claim; any those skilled in the art are not within breaking away from spirit and scope of the present utility model; can make possible change and modification, the scope that therefore protection domain of the present utility model should be defined with the utility model claim is as the criterion.
