Abstract
The utility model relates to a full automatic electric lifter of a cab, which comprises a lifting machine and an electric control device, wherein the electric control device comprises a power source, an electric oil pump, a stop button, a lifting control device and a falling control device; the lifting control device comprises a lifting button, a relay, a travel switch and an indicator light; the falling control device comprises a falling button, a relay, a travel switch, an indicator light and an electromagnetic reversing valve. The utility model realizes the full automatic control of the lifting and the falling of the cab and has the advantages of simple operation and high safety.
Description
(1) technical field
The utility model relates to a kind of automobile cab lifting device, the electronic lifting device in particularly a kind of full-automatic driving chamber.
(2) background technology
The existing electronic lifting device of operator's compartment is electronic adding manually, does not realize automatic function fully, increases the labour intensity and the intense strain of chaufeur.
(3) summary of the invention
The utility model provides a kind of full-automatic electric lifting device,, safe ready simple to operate to realize in order to solve the deficiency that operator's compartment can not the full automaticity lifting.
The purpose of this utility model is achieved in that
The electronic lifting device in full-automatic driving of the present utility model chamber includes lifting mechanism, electric controller, and described electric controller comprises power supply, motor, electric oil pump, stop button, lifting control setup and descending control device; Described lifting control setup includes lifting button, lifting relay, lifting travel switch and lifting indicator lamp; Described descending control device includes decline button, down relay, descending stroke switch, decline indicator lamp and solenoid directional control valve; Motor, electric oil pump, stop button and lifting button, lifting relay, lifting travel switch are connected into the lifting loop; Motor, electric oil pump, stop button and decline button, down relay, descending stroke switch series are unified into the decline loop.
The electronic lifting device in full-automatic driving of the present utility model chamber, in order to realize the automatic guidance function better, described lifting button and decline button are the moving button of often opening of the wink of tape light, described stop button is a moving stop button of wink; Described relay has two pairs of open contacts.
The utility model is replaced the hydraulic manual oil pump with electric oil pump on the basis of original manually upset operator's compartment, replace hand change over valve with solenoid directional control valve, increase moving knob, two relays, the full automaticity of the operation of realization of stopping of moving push switch of two winks, a wink of tape light.
The beneficial effects of the utility model are, have realized the lifting and the decline of full automatic control operator's compartment, have simple to operate, safe.
(4) description of drawings
Fig. 1 is a circuit control principle scheme drawing of the present utility model
Fig. 2 is the connection diagram of former hand-hydraulic lifting device
Fig. 3 has the connection diagram of novel lifting device for this reality
Among the figure, JS-lifting knob, XJ-decline button, TZ-stop button, K1, K2-relay, the magnet coil of K3 solenoid directional control valve, 1ZSD, 2ZSD-indicator lamp, 1C, 2C relay contact, 1XK, 2XK-travel switch, DDB-motor
(5) specific embodiment
Below in conjunction with accompanying drawing present embodiment is made specific description.The electronic lifting schematic diagram of present embodiment as shown in Figure 1, connection diagram institute is shown in Figure 3.
When pressing lifting knob JS, relay k1 starting, contact 1C closure, indicator lamp 1ZSD is bright, and electric oil pump DDB starts working, and promptly begins lifting, when giving rise to certain angle, operator's compartment is run into travel switch, and 1XK opens with travel switch, relay electric-loss, contact 1C opens, electric oil pump quits work, and indicator lamp 1ZSD goes out, and lifting stops.
In like manner want to allow operator's compartment descend, pressing descends turns round XJ, and electromagnetism changes the magnet coil k3 and the relay K 2 of valve and works simultaneously, solenoid directional control valve commutation, the contact 2C closure of relay k2, electric oil pump work, indicator lamp 2ZSD indication.When operator's compartment dropped to level attitude, travel switch 2XK opened, relay k2 dead electricity, and corresponding contacts is opened, and indicator lamp 2ZSD goes out, and electric oil pump quits work, and operator's compartment descends and stops.
If stop lifting or decline in the lifting way, by stopping button TZ, electric oil pump promptly quits work, and operator's compartment has been parked in half-way.
Claims (2)
