Shown in Fig. 1,2, the utility model comprises vehicle frame 5, and 1, two group of pallet fork wheel 1 of pallet fork wheel is installed in respectively on the pallet fork 2, pallet fork 2 is connected with lift oil tank 3, lift oil tank 3 is configured on the door frame 4, and door frame 4 is connected on the vehicle frame 5, and the cross member of frame 7 of vehicle frame 5 is connected with supporting mechanism 6.
With reference to shown in Figure 3, the formation of supporting mechanism 6 is connected an end of telescopic oil cylinder 14 by bearing pin 18 by flexible outer arm 10, the other end of telescopic oil cylinder 14 is connected with flexible inner arm 13 by bearing pin 15, be provided with slide block 11 between flexible outer arm 10 and the flexible inner arm 13, flexible inner arm 13 connects an end of folding oil cylinder 12 by bearing pin 9, the other end of folding oil cylinder 12 is connected by bearing pin 24 with support outer arm 21, connecting panel 16 is by the end joint connection of bearing pin 17 with flexible inner arm 13, connecting panel 16 is welded in and supports on the outer arm 21, one end of support cylinder 23 is connected by bearing pin 19 with support outer arm 21, the other end of support cylinder 23 is connected by bearing pin 25 with support inner arm 22, support outer arm 21 and being provided with slide block 20 with supporting between the inner arm 22, magnet stopper 8 is installed on the wheel hub of support wheel 27 and is installed on the tail end of support inner arm 22 by axle 26.
Flexible outer arm 10, flexible inner arm 13, support outer arm 21, support inner arm 22 are rectangular steel pipe, drive by bearing pin by the oil cylinder in the arm separately and to carry out fore and aft motion, be provided with slide block 11 between flexible outer arm 10 and the flexible inner arm 13, be used to reduce the resistance of fore and aft motion; Lift oil tank 3, telescopic oil cylinder 14, folding oil cylinder 12, support cylinder 23 are the bidirectional piston cylinder.Oil cylinder provides pressure oil by the fork truck Hydraulic Pump, operate by wireless remote control, receiver of remote-control sytem inputs to Programmable Logic Controller after receiving instruction, and Programmable Logic Controller is controlled corresponding solenoid valve according to order, makes pressure oil enter corresponding oil cylinder and makes it produce fore and aft motion.The motion of lift oil tank 3 can make pallet fork 2 up-and-down movements; The motion of telescopic oil cylinder 14 can make flexible inner arm 13 seesaw with respect to vehicle frame together with the supporting mechanism other parts; Folding oil cylinder 12 can make support inside and outside arm vertically or level lie down, support cylinder 23 can make vertically the time and support the inner arm up-and-down movement supporting inside and outside arm 22,21.Be provided with magnet stopper 8 in the support wheel 27, can brake support wheel 27 or free braking by remote controller.
With reference to shown in Figure 4, described control circuit 28 is by receiver of remote-control sytem 29, Programmable Logic Controller 30, R/G 31, electromagnetic valve group is that car load hoists/decline electromagnetic valve 32, stretch out/withdraw electromagnetic valve 33, vertically/folding electromagnetic valve 34, lifting/decline electromagnetic valve 35 is supported in the back, lift oil tank electromagnetic valve 36, magnet stopper 8 is formed, the mouth of receiver of remote-control sytem 29 connects an input end of Programmable Logic Controller 30, the mouth of Programmable Logic Controller 30 connects each coil assembly input end of relay respectively, the tip side of R/G 31 connects car load respectively and hoists/decline electromagnetic valve 32, stretch out/withdraw electromagnetic valve 33, vertically/folding electromagnetic valve 34, lifting/decline electromagnetic valve 35 is supported in the back, lift oil tank electromagnetic valve 36, the input end of magnet stopper 8, other end ground connection.
Working process is as follows:
During the self-chambering of fork truck, enter readiness, fork truck is stretched out fully by folding oil cylinder 12 earlier, makes that to support inside and outside arm 22,21 vertical.By travel and lift oil tank 3 raises pallet fork wheel 1 and under be pressed on the auto carriage board.
Under remote manipulation, fork truck passes through the withdrawal of lift oil tank 3, and then makes further pressing down of 1 pair of auto carriage board of pallet fork wheel, because auto carriage board can not continue sinking, so the first half of fork truck just begins the built on stilts upward movement; Meanwhile, support cylinder 23 is stretched out motion, makes support inner arm 22 drive support wheels 27 and moves downward, and after support wheel 27 touched ground, the latter half of fork truck had also left the ground upward movement; Since lift oil tank 3 and support cylinder 23 simultaneously, be synchronized with the movement, so the vehicle frame 5 of fork truck remains horizontality and can not tilt in uphill process.
When fork truck was raised to highest point, when pressing remote controller key again, the telescopic oil cylinder 14 of fork truck moved, support wheel braking simultaneously.Because outer arm 22,21 can not move backward at support wheel 27 glancing impacts in supporting, and fork truck vehicle frame 5 is travelled forward, and the fork truck front-wheel is entered in the automobile bodies.
Fork truck by lift oil tank 3 and support cylinder 23 simultaneously, move downward synchronously moves downward vehicle frame 5, is pressed on the auto carriage board up to the fork truck front-wheel.
Fork truck support wheel 27 braking is removed, and travels by front-wheel the fork truck trailing wheel is also entered in the automobile bodies.
Because fork truck vehicle frame 5 has entered in the automobile bodies fully, support inner arm 22 so be recoverable to.Fork truck withdraws support inner arm 22 by the retraction movement of support cylinder 23 fully.
Fork truck withdraws flexible inside and outside arm 13,10 by the retraction movement of telescopic oil cylinder 14 fully.
Fork truck lies down inside and outside arm 13,10 levels of support by the retraction movement of folding oil cylinder 12.
So far, fork truck has just been finished from process of assembling.
The process of fork truck self-unloading is with opposite fully from process of assembling, and the motion process of each oil cylinder is also opposite.
