3. control setup of the present utility model has automatically and manual two kinds of functions, uses more conveniently, and has loaded onto indicator lamp and buzzer phone, can indicate and remind the mode of operation of your electromagnet.
Accompanying drawing drawing of the present utility model is described as follows:
Fig. 1 is built-in power supply formula lifting electromagnet front view.
Fig. 2 is a constructional drawing.
Fig. 3 is the control setup circuit diagram.
The present invention will be described in further detail in conjunction with the accompanying drawings.
In Fig. 1 and Fig. 2, a shell 8 is housed above the electromagnet 7, electromagnet is that coil, magnetic pole and electromagnet housing are formed, and for general common electromagnet, does not cut open among the figure.Storage battery 9 and control setup 11 are housed in the housing 8, and storage battery 9 is built-in power supplys.One opening is arranged on the housing above the storage battery, a storage battery protecting cover 10 is housed on it, open protecting cover, can change storage battery or charge a battery.On housing 8, be welded with two hangers 2, between two hangers, load onto an automatic briquetting 1, on the briquetting lifting hole(eyelet) 12 is arranged automatically, can hang on the suspension hook of hoisting crane with two pins 3.Automatically two pin-and-holes on the briquetting 1 are elongated hole, make briquetting that the motion of certain limit can be arranged up and down.A two-way automatic switch 4(be housed be the two-way automatic switch K among Fig. 3 on the housing below briquetting
4).A handle 6 respectively is housed in the housing both sides.In the front of housing electric-control board 5 is housed, volt meter, amperemeter/ammtr, three switches and indicator lamp are housed on the panel.Electric-control board 5 and all the included devices of control circuit that are contained in the housing 8 have constituted control setup 11, each device that do not draw among the figure, but represent whole control setup with frame of broken lines.
The working process of two-way automatic switch 4 is: when electromagnet from dropping to ground in the air, briquetting 1 is pressed in downwards on the automatic switch 4 automatically, switch connection (being the position of the C shown in Fig. 3), the coil in the electromagnet is switched on, electromagnet produces suction.Pick up hanging object, when electromagnet lifted by crane, briquetting broke away from automatic switch 4 automatically, and switch still is in conducting state.When electromagnet once more from dropping to ground in the air, briquetting compresses switch 4 once more, switch 4 disconnects, electromagnet is no longer worked, and object that is picked up and electromagnet break away from, when at this moment electromagnet lifts by crane, briquetting breaks away from switch, and switch still is in the situation of cutting out, and finishes a working cycle to this.
In Fig. 3, power supply E is storage battery (being 9 among Fig. 2), is connected to source switch K on the positive source

2All be connected with SJ with power cathode.ZJ
1And be connected to indicator lamp H and buzzer phone F between the power cathode, after indicator lamp H and the buzzer phone F parallel connection, be serially connected on the circuit.
Because select switch K is arranged in control circuit
2, the utility model can manually be controlled, also can automatic guidance.Work as K
2Be that it is manual investing position f automatically when investing position e.
When automatic guidance, i.e. K
2When investing the e position, working process is: K
1Guan Hehou is by means of the two-way automatic switch K of gravity pressure of automatic briquetting 1
4Invest position d, ZJ
1Must be electric, its normally open contact closure, indicator lamp H is bright, and buzzer phone F sends the sound.While electromagnet 7 gets electric, and direction of current is a to b.Volt meter and amperemeter/ammtr all have indication.This moment, electromagnet entered mode of operation, picked up the iron and steel object.
Sling the iron and steel weight when arriving the destination and putting down weight at electromagnet, and briquetting will be pressed automatic switch K once more automatically
4, make it to invest position c, so DC contactor ZJ
1Outage, H and F and electromagnet all cut off the power supply.Pizo-resistance when work of electromagnet, because of voltage is power line voltage, its not conducting.But when electromagnet cut off the power supply, under induced electric motive force (more much higher than the power line voltage) effect that magnet coil produces, it was with breakdown conducting, for electromagnet provides a discharge loop that discharges the electromagnetism energy storage.
At K
4When investing position c, contactless switch ZJ
2Must be electric, electromagnet is through current-limiting resistance R
1Must be electric, but electric current is conversely, to a, carries out contrary magnetic by b, quickens the absorbate body is laid down.The contrary magnetic time is controlled by time relay sj.ZJ
2Electric then SJ also electric, when time-delay finishes, the disconnection of the normally closed interlock of SJ, ZJ
2Outage, contrary magnetic knot bundle.So far, an automatic working process finishes.
In the time of manually, with select switch K
2Invest position f, utilize hand switch K
2Invest d or c position and operate the through and off of electromagnet, its process is identical with automatically the time.
