Abstract
The utility model relates to a vehicle-mounted wired control switching device of a trailer. The vehicle-mounted wired control switching device of the trailer comprises a solenoid valve (1), a relay (3) and a power source (2), and is characterized in that the solenoid valve (1) is connected with a pin 2 and a pin 3 of a contact switch K4 of the relay; a pin 5 of the contact switch K4 of the relay is connected with a pin 1 of a remote switch K3 and a pin 3 of a change-over switch K1; a pin 6 of the contact switch K4 of the relay is connected with a pin 2 of a vehicle-mounted switch K2; the relay (3) is connected with a pin 2 of the remote switch K3; the power source (2) is connected with a pin 1 of the change-over switch K1; a pin 2 of the change-over switch K1 is connected with a pin 1 of the vehicle-mounted switch K2; a pin 3 of the change-over switch K1 is connected with a pin 1 of the remote switch K3. According to the vehicle-mounted wired control switching device, operation staff can timely and accurately finish operation and can see the actual situation of operation points clearly, operation is easy, working efficiency is high, and safety and reliability are achieved.
Description
Technical field
The utility model belongs to trailer control setup, particularly a kind of trailer vehicle-mounted and have line control transfer device.
Background technology
Trailer is when carrying out operation, because rising arm is longer, setting is distant apart from operating personal, during one-man service, operating personal can not be seen actual state that even can't see setting clearly clearly, and during double operation, also may be because of can not promptly and accurately fulfiling assignment with the inaccurate operating personal that caused not in time of linking up, and can not well be guaranteed for the safety of work.
Summary of the invention
The object of the invention is to overcome above-mentioned technical deficiency, a kind of telecontrol engineering that utilizes is provided, reduce the operation easier of operating personal, increase work efficiency, improve trailer vehicle-mounted of safety and precise and have line control transfer device.
The technical scheme that technical solution problem of the present invention adopts is: a kind of trailer vehicle-mounted and have line control transfer device, comprise electromagnetic valve, relay and power supply, and it is characterized in that electromagnetic valve is connected with 2,3 pin of relay switch K4; 5 pin of relay switch K4 connect 1 pin of teleswitch K3 and 3 pin of change-over swith K1, and 6 pin connect 2 pin of vehicle-mounted K switch 2; Relay is connected with 2 pin of teleswitch K3; Power supply connects 1 pin of conversion K switch 1; 2 pin of change-over swith K1 connect 1 pin of vehicle-mounted K switch 2, and 3 pin connect 1 pin of teleswitch K3.
The beneficial effects of the utility model are: this utility model has guaranteed that operating personal can promptly and accurately fulfil assignment, and can see clearly the actual conditions of setting clearly, processing ease, and work efficiency is high, safe and reliable.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, with embodiment, illustrate.
Figure is the vehicle-mounted of trailer and has line control transfer device.
In figure: 1-electromagnetic valve; 2-power supply; 3-relay; K1-change-over swith; The vehicle-mounted switch of K2-; K3-teleswitch; K4-relay contact switch.
The specific embodiment
Embodiment, with reference to accompanying drawing, a kind of trailer vehicle-mounted and have line control transfer device, comprises electromagnetic valve 1, relay 3 and power supply 2, it is characterized in that electromagnetic valve 1 is connected with 2,3 pin of relay switch K4; 5 pin of relay contact switch K4 connect 1 pin of teleswitch K3 and 3 pin of change-over swith K1, and 6 pin connect 2 pin of vehicle-mounted K switch 2; Relay 3 is connected with 2 pin of teleswitch K3; Power supply 2 connects 1 pin of conversion K switch 1; 2 pin of change-over swith K1 connect 1 pin of vehicle-mounted K switch 2, and 3 pin connect 1 pin of teleswitch K3.Relay contact switch K4 controls folding by relay 3.
Vehicle-mounted K switch 2 and teleswitch K3 are self-resetting switch, and change-over swith K1 is third gear switch, and midway location is lock catch, and relay 3 is double pole double throw.When change-over swith K1 gets to vehicle-mounted shelves, vehicle-mounted K switch 2 obtains electric closure, normally closed contact by relay 3 obtains electric, and hydraulic work system, when change-over swith K1 gets to remote control shelves, other one group of contact (3,4 pin) of one end of teleswitch K3 and relay 3 obtains electric, closed teleswitch K3, electromagnetic valve 1 obtains electric, hydraulic work system, simultaneously vehicle-mounted K switch 2 disconnects, he just isolates vehicle-mounted K switch 2 with electromagnetic valve 1 completely like this, avoids affecting other similar switches, accomplishes the end in view.
