Description

A kind of Pneumatic power elevator apparatus

One, technical field:

The present invention relates to a kind of lifting mechanism, specifically is the Pneumatic power elevator apparatus that a kind of factory conveyor line handling goods uses.

Two, background technology:

On the machinery and equipment flow production line, heavy machine is moved down, brings up to from conveyor line is often to have plenty of.For example, driving engine will be packed with carton before dispatching from the factory, present method is that the driving engine that will finish on the conveyor line after several operation is taken in one's arms driving engine by a workman from conveyor line, in the outer packing chest of the conveyor line that is placed on, and then by two workmans it is upwards lifted on the conveyor line of doing that flows and to enter next procedure.This procedure is all finished by 2 people for a long time, both requires great effort, and takes the people again.

Three, summary of the invention:

The purpose of this invention is to provide a kind of both laborsavingly, economize a kind of Pneumatic power elevator apparatus of flow production line of people again.

Concrete scheme of the present invention is: a kind of Pneumatic power elevator apparatus, be respectively arranged with loam cake or lower cover at the upper and lower port of cylinder bucket, in the cylinder bucket, be contained in " ⊥ " shape cylinder axis, its key is: stretch out outside cylinder bucket and the loam cake described cylinder axis upper end, is connected with the bench board of being made up of cylinder, drum shaft, support and connecting screw rod; Cylinder in the described bench board is rack-mount by the drum shaft arrangement in parallel, and at middle part, the bottom surface fixed installation connecting screw rod of this support, this connecting screw rod lower end is threaded with described cylinder axis; At described loam cake and cover down be equipped with communicate with cylinder inner cavity on ventilation flue or downtake, this upper and lower ventilation flue's outer end is installed on the foot-operated air valve switch, this foot-operated air valve switch is provided with admission piece.

Described foot-operated air valve switch is the threeway check valve, and wherein the valve that the ventilation flue opens in the control is the normally open valve door, and the valve that the control downtake is opened is a normal closed gate.

Described cylinder is installed in the cylinder frame, and lower cover of air cylinder is through the bottom surface of screw retention at cylinder frame; The end face of cylinder frame is stretched out in described cylinder axis upper end.

The present invention is provided with bench board above cylinder, bench board rises, descends with the cylinder axis in the cylinder, moving axially of cylinder inside cylinder axle by foot-operated air valve switch control, when unloading under need be with the goods on the conveyor line, only need bench board is dropped to the position lower than conveyor line, goods on the conveyor line is taken in one's arms, be placed in the packing chest on the bench board; When needs are put back to packaged goods on the conveyor line, only need foot-operated air valve switch that bench board is risen on the plane concordant with conveyor line, promote goods, goods is got back on the conveyor line.Whole process is simply laborsaving, and a people just can finish.

Adopt the beneficial effect of such scheme to be: simple to operate, laborsaving, quick, reliable, production efficiency is high, a people just can independently finish, and is a kind of and the supporting ideal equipment of packaging line.

Four, description of drawings:

Fig. 1 is a structural representation of the present invention;

Fig. 2 is the A-A cutaway view of Fig. 1;

Fig. 3 is the B-B cutaway view of Fig. 1.

Five, the specific embodiment:

Please referring to Fig. 1, Fig. 2, Fig. 3, the present invention is mainly by cylinder 1, drum shaft 2, support 3, connecting screw rod 4, cylinder frame 6, loam cake 7, cylinder bucket 8, cylinder axis 9, lower cover 10, screw 11, last ventilation flue 12, downtake 13, foot-operated air valve switch 14, air valve noise silencer 15, admission piece 16 is formed, wherein on cylinder bucket 8, lower port is respectively arranged with loam cake 7 or lower cover 10, be contained in " ⊥ " shape cylinder axis 9 in cylinder bucket 8, stretch out outside cylinder bucket 8 and the loam cake 7 and by cylinder 1 these cylinder axis 9 upper ends, drum shaft 2, support 3 is connected with the bench board that connecting screw rod 4 is formed; Described cylinder is installed in the cylinder frame 6, and lower cover of air cylinder 10 is fixed on the bottom surface of cylinder frame 6 through screw 11, and the end face of cylinder frame 6 is also stretched out in cylinder axis 9 upper ends.Cylinder 1 in the described bench board is installed in (as shown in Figure 2) on the support 3 by drum shaft 2 arrangement in parallels, is installed with connecting screw rod 4 at the middle part, bottom surface of this support 3, and these connecting screw rod 4 lower ends are threaded with described cylinder axis 9; Be equipped with on described loam cake 7 and the lower cover 10 communicate with cylinder inner cavity on ventilation flue 12 or downtake 13, the outer end that should go up ventilation flue 12, downtake 13 is installed on the foot-operated air valve switch 14, this foot-operated air valve switch 14 is provided with admission piece 16, also is provided with air valve noise silencer 15 at admission piece 16 homonymies.Described foot-operated air valve switch 14 is threeway check valves, and wherein the valve that ventilation flue 12 opens in the control is the normally open valve door, and the valve that control downtake 13 is opened is a normal closed gate.

Principle of work: device of the present invention is placed on the other position that needs of driving engine packaging line, pressure gas is inserted admission piece 16, and at this moment, pressure gas enters in the cylinder bucket 8 through last ventilation flue 12, cylinder axis 9 bottoms are positioned at cylinder bucket 8 bottoms, and bench board is positioned at lower position.When unloading under need be with the driving engine on the conveyor line, only need bench board is dropped to the position lower than conveyor line, on bench board, put packing chest, driving engine on the conveyor line is taken in one's arms, be placed in the packing chest on the bench board, after to be packaged the getting well, foot-operated air valve switch 14, the valve of ventilation flue's 12 ventilations is closed gradually in the control, the valve of control downtake 13 is opened gradually, pressure gas enters in the cylinder bucket 8 by downtake 13, promotes cylinder axis 9 and moves up, thereby bench board is lifted gradually, when bench board rises to the position concordant with conveyor line, promote driving engine, packaged driving engine can be put back on the conveyor line, enter next procedure.Because bench board is provided with cylinder 1, when bench board rose to the position concordant with conveyor line, cylinder 1 was parallel with the conveyor line sense of motion, and a people promotes driving engine, just can easily shift driving engine on the conveyor line onto, and is very laborsaving.
