Further, described lift cylinder 5 fixes on the ground on the lift cylinder plate 502 that has.
Principle of work of the present invention is: time initial, electromagnet 4 is in "on" position, and the actuating spindle 401 of electromagnet 4 shrinks and do not contact with hinged block 15, thus makes road wheel 2 movable.The output shaft of servomotor 36 drives rotating screw bolt 35 to rotate, and drives walking block 30 to carry out parallel motion, thus drives road wheel 2 and material plate 1 parallel motion to carry out the carrying of material.When detection projection 12 is close to inductor 3, inductor 3 detects material plate 1 and sends a signal to main control system (not shown), servomotor 36 is controlled out of service by main control system, simultaneously, main control system controls electromagnet 4 power-off, the actuating spindle 401 of electromagnet 4 flicks and resets and be plugged in the limited impression 11 of hinged block 15, thus is locked by road wheel 2, then again makes electromagnet 4 be energized when material plate 1 needs mobile.By the stop position regulating the position of inductor 3 and electromagnet 4 to adjust material plate 1.
When needing the material carrying eminence or lower, only need start lift cylinder 5, the axis of the piston 501 of lift cylinder 5 drives material plate 1 to be elevated.When material plate 1 rises, Plug Division 21 pulling force be subject to upwards makes the steel ball automatic telescopic of connecting ball head plunger 32, because Plug Division 21 to be provided with in vertical curve arrangement and the equal grafting shrinkage pool 22 of spacing, namely steel ball automatic spring is nested completes rising to the grafting shrinkage pool 22 of relevant position; When material plate 1 declines, namely the steel ball automatic telescopic of connecting ball head plunger 32 is nested completes decline to the grafting shrinkage pool 22 of relevant position.
When needs dismounting material plate 1, only need first the piston rod 501 of lift cylinder 5 to be disassembled from material plate 1, then it can unload by upwards drawing of being exerted oneself by material plate 1 from walking block 30, installs and unloads carried convenient.
In sum, the present invention is by the rotating screw bolt 35 driven by servomotor 36 that is spirally connected in walking block 30, and rotating screw bolt 35 rotates and drives walking block 30 to move linearly, and realizes material dolly and automatically walks, save manual labor; By arranging Plug Division 21 in material plate 1 bottom surface and being connected with walking block bulb plunger 32, dolly easy removal can be got off from walking block 30; By arranging buffer gear 10 between road wheel 2 and material plate 1, make material plate 1 operationally vibrate minimizing, material not easily drops out; By connecting lift cylinder 5 in material plate 1 bottom surface, make material plate 1 can automatic lifting, handling eminence material be convenient; By shift mechanism 60, inductor 3 is arranged on adjustable track 50, makes the position of inductor 3 adjustable, thus make the stop position of dolly adjustable; By on adjustable track 50, electromagnet 4 is set and actuating spindle 401 power-off of electromagnet 4 time be plugged in the limited impression 11 of buffer gear 10, can by road wheel 2 latched position, thus fixing little truck position, enhance productivity.
The raw material floor truck that can automatically walk provided by the present invention; be only the specific embodiment of the present invention; but protection scope of the present invention is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; change can be expected easily or replace, all should be encompassed within scope.Therefore, protection scope of the present invention should be as the criterion with the protection domain of described claim.
