Description
Technical field
The utility model is related to lifting magnet technical field, and in particular to a kind of lifting of use PLC programmable devices control is forever
Magnet.
Background technology
Hoisting permanent magnet is a kind of magnetic force using permanent magnet come the magnetic force suspender of handling steel plate.Magnetic common at present is closed circuit
Conversion on formula hoisting permanent magnet between magnetic and demagnetization, is, by its internal rotary pole, to rotate to different positions and come real
Existing.And to realize the change of this position, it is desirable to an additional mechanics mechanism and make this mechanics mechanism move institute
The power needed.Implementation method substantially has this two kinds：One class is to be moved up and down completely by travelling crane hook as power source, drives it
Mechanics mechanism --- mechanical arm spins upside down, click rotation, the then rotation of band movable sprocket is then driven, so that inside it
The rotary part upper magnetic that is in different positions to realize and demagnetization.This is a kind of pure mechanical energy mode, but for
Need to join the place hung, a kind of this mode with many it is difficult to ensure that absolutely synchronism, such as Patent No.
ZL200420035639.5 patent.Another kind of is to provide electric energy by power supply, is driven by motor and reducing gear inside it
Movable part --- rotary pole is gone to upper magnetic and the demagnetization that different positions are realized.But due to the relay in control circuit
The components such as device easily break down in frequently acting, and cause the reliability of whole device not high, such as Patent No.
ZL201320448589.2 patent.In addition, conventional technical scheme is generally immature, what is had does not take into account suction slab well
With the difference of thin plate, what is had has material and without security needs when expecting etc. without solution well.
The content of the invention
The utility model provides a kind of hoisting permanent magnet of use PLC programmable devices control, can solve aforementioned drawback.
The hoisting permanent magnet controlled using PLC programmable devices, by hoisting permanent magnet body, control circuit, shell, deceleration electricity
Machine, sprocket wheel, chain, magnetic switch, remote control etc. are constituted.Its operation principle is：By control circuit to hoisting permanent magnet device
It is powered, reducing motor rotation drives the magnetic pole motion of hoisting permanent magnet body interior, so that it may device is in suction or blowing shape
State.
Control circuit principal part is arranged within shell, and associated each sensing original paper is arranged on inside or around device,
Each magnetic switch, remote control switch are connected by indicator lamp with PLC programmable devices, and PLC programmable device output ends are connected to each output par, c, then
It is connected on forward and backward relay, and connects motor, upper magnetic and demagnetization is realized in the way of motor driving magnetic pole rotation, can be real
Existing suction size it is stepless adjustable, and with detection operations face whether there is material, identification steel plate thickness, detection safe operation state,
The functions such as remote-controlled operation.
Following functions module is provided with control system：Material is whether there is to detect using magnetic switch, it is ensured that only on steel plate
Work suction is just produced during face；Steel plate thickness is recognized using magnetic switch, difference is inhaled difference when putting slab and thin plate, prevented
Thin plate is inhaled to drop；Ensured using spacing magnetic switch safe during plant running；Remote control switch is set, to facilitate remote behaviour
Make.
Control circuit of the present utility model is as shown in Figure 1：Each magnetic switch A1-A4, remote control switch A5 are by indicating
Lamp is connected with PLC programmable devices；PLC programmable device output ends are connected to each output par, c P and S；P and S output end be connected to just,
Invert on relay JS, and connect motor M.
The course of work of the present utility model is：Hoisting permanent magnet device is put into by suction steel plate, magnetic switch A1 is detected
To on steel plate surface and having an action；By suction steel plate it is thicker when, magnetic switch A2 action；When by suction steel plate than it is relatively thin when, magnetic
Property switch A2 akinesias；The internal magnetic pole of device is in upper extreme position, magnetic switch A3 actions；The internal magnetic pole of device is in down
Extreme position, magnetic switch A4 actions；When wireless remote control operation, magnetic switch A5 is actionable.These dynamic or motionless signals are equal
The processing of PLC programmable devices is entered, then by PLC programmable devices output current to output par, c P, is controlled by forward and backward relay JS
Motor M positive and negative rotation.
