Description of drawings:
Accompanying drawing 1 is control circuit figure of the present utility model
The specific embodiment:
Be embodiment of the present utility model with the Fig. 1 that bows now, the utility model is further detailed.
The utility model is an electronic control package, and its major technique parts are a Programmable Logic Controller and electromagnetic valve.On oil circuit four wheels and that rise and descend of vehicle electromagnetic valve is installed all, the open and close of these electromagnetic valves are controlled by described Programmable Logic Controller.Programmable Logic Controller is the 12/24RC model of the LOGO series of existing Siemens Company, and its core is made of main frame 1 and expansion module.Input end at described Programmable Logic Controller is connected with a switch circuit, at control executive circuit of mouth connection of described Programmable Logic Controller; Propons master cock S1 in the described switch circuit and back axle master cock S2 connect on 11 and 12 terminals of Programmable Logic Controller main frame, parallel series has normotopia indicator lamp RZD1, RZD2, returning positive justification K switch 13 connects on 13 terminals of Programmable Logic Controller main frame, described Pattern Select Switch is connected on 14,15,16 terminals of Programmable Logic Controller main frame, the driving direction switch K15 of book be connected on 11,12 terminals of described Programmable Logic Controller expansion module; Described crab type turns to electromagnetic valve YA1 to be connected on the Q1 terminal of Programmable Logic Controller main frame, four-wheel steering electromagnetic valve YA2 is connected on the Q2 terminal of Programmable Logic Controller main frame, the front-wheel steering indicator lamp is connected on the Q3 terminal of Programmable Logic Controller main frame, the front-wheel positive electromagnetic valve YA3 that turns right back is connected on the Q4 terminal of Programmable Logic Controller main frame, brake drum of front wheel right hand and left hand is passed back on the Q1 terminal that positive electromagnetic valve YA4 is connected on the Programmable Logic Controller expansion module, the convertible valve electromagnet is connected on the Q3 terminal of Programmable Logic Controller expansion module, the decline electromagnet is connected on the Q2 terminal of Programmable Logic Controller expansion module, and vertical electromagnet is connected on the Q4 terminal of Programmable Logic Controller expansion module.
In order to prevent when tractor truck turns to, to run into obstacle, reduce than necessary loss, on 17 terminals of the input end of Programmable Logic Controller, be connected with neutral position switch, on 18 terminals, connect an anti-collision switch.
Working process of the present utility model is as follows:
The working process of mode converting part:
S1 is a bit switch in the propons, and when propons two-wheeled normotopia, indicator lamp RZD1 is bright; S2 is a bit switch in the back axle, and when back axle two-wheeled normotopia, indicator lamp RZD2 is bright; K13 is back the positive justification switch, when not timing of trailing wheel appears in long-term work, can move this switch and adjust.K14 is a Pattern Select Switch, and it is three rocker switchs, and corresponding three kinds turn to pattern respectively, and both crab shape turned to, four-wheel steering and front-wheel steering.
When forward adjusting switch K13 was in the closed position, the change speed gear box of tractor truck was in neutral gear position, when K14 pushes another position from a position, if it is bright that the front-wheel indicator lamp does not have, YA3, the YA8 hydraulic electromagnet gets, wheel will be turned right, behind the certain hour, if front-wheel meta indicator lamp does not also have bright, YA4, YA8 hydraulic electromagnet get electric, and a wheel left side passes, and is bright up to the propons indicator lamp, at this moment, the model selection success, the pattern indicator lamp before the conversion extinguishes, and the pattern indicator lamp after the conversion is bright.Corresponding hydraulic electromagnet gets electric, and any one among YA3, YA4, the YA8 be dead electricity all.
When the change speed gear box of tractor truck is in non-neutral gear position, any one among YA3, YA4, the YA8 can not get electric, but bearing circle rotates, and the propons two-wheeled is during through midway location, and propons meta indicator lamp is bright, and model selection also can be successful.Pattern indicator lamp before the conversion extinguishes, and the pattern indicator lamp after the conversion is bright, and corresponding hydraulic electromagnet gets electric, and any one among YA3, YA4, the YA8 be dead electricity all.
The working process of revolution adjustment member:
After at first allowing tractor truck be in four-wheel or crab shape pattern, pull adjusting switch K13, again select switch is pulled the front-wheel mode converting and successfully promptly finished adjustment.
The working process of anti-collision lifting part:
Under the normal circumstances, when the cab lift switch was pulled hoisting position, hydraulic electromagnet YA6 got, operator's compartment raises under the effect of tractor truck hydraulic actuating cylinder, and when the cab lift switch was pulled lowering position, hydraulic electromagnet YA7 got, under the effect of hydraulic actuating cylinder, operator's compartment descends.When any one anti-collision switch on being located at the tractor truck relevant position ran into obstacle, no matter where direction switch was in, and operator's compartment call instruction at once drops to the position of leaving obstacle, and promptly anti-collision is preferential.
