Abstract
The invention discloses a kind of bridge crane electromagnetic lifter angle automatic station-keeping system, including air switch, programmable controller, button, switch, frequency converter, motor, electronic compass and gyroscope, the air switch is through the frequency converter and the motor connection；The programmable controller is connected with the air switch, and the electronic compass and the gyroscope are connected with the programmable controller, and the output end of the programmable controller is connected with the frequency converter.The present invention is automatically positioned that there is provided plant not only to be avoided that electromagnetic lifter was disturbed but also can solve the problems, such as the scheme of initial angle by what the advantage of gyroscope and electronic compass was simultaneously used in bridge crane electromagnetic lifter angle.
Description
Technical field
The present invention relates to crane component part technical field, especially a kind of bridge crane electromagnetic lifter angle is automatically positioned
System.
Background technology
Bridge crane is one of essential important tool of production of industrial and mining enterprises, especially in iron and steel enterprise, in order to
The quick transport and handling of product need, and many bridge cranes install magnechuck suspender under suspension hook（Abbreviation electromagnetic lifter）Come
Lifting operation is carried out, the efficiency of production is effectively increased.When unloading rod line steel, in order to stack neat, safety, need
By rod line between layers by 90 degree of intersection stackings, if the direction of factory building is defined as 0 degree, then electromagnetic lifter is accomplished by accordingly
Frequently adjusted between 0 degree and 90 degree；The substantially artificial operation motor of the rotation control of current electromagnetic lifter carries out the angle of electromagnetic lifter
Degree adjustment, because hanging apparatus has used steel wire rope and chain sling flexible tool, the angle adjustment to electromagnetic lifter is brought very big tired
Difficulty, causes efficiency low and labor intensity is big；Therefore, a kind of bridge crane electromagnetic lifter angle automatic station-keeping system is very necessary
's.
Accomplish that bridge crane electromagnetic lifter angle is automatically positioned, just must be known by what angle shape electromagnetic lifter is currently at
State.The sensor of angle can be measured at present gyroscope, electronic compass etc..The advantage of gyroscope is shadow not by electromagnetic interference
Ring, have the disadvantage that the angle direction of object original state can not be measured；Gyroscope is in initial power-on, by the angle state of object
0 degree is defined as, if only the angle detecting sensor for being used as electromagnetic lifter with gyroscope, then upper electricity will be right first every time
The angle of electromagnetic lifter is adjusted, and such scheme is just very time-consuming laborious；The advantage of electronic compass is that energy detection object is any
When angle state, shortcoming is susceptible to electromagnetic interference, and electromagnetic lifter produces very big electromagnetic attraction in lifting, certainly will
Strong interference is carried out to electronic compass.
The content of the invention
The present invention in view of the shortcomings of the prior art, proposes a kind of bridge crane electromagnetic lifter angle automatic station-keeping system, knot
Structure is simple, easy to use accurate.
In order to realize foregoing invention purpose, the present invention provides following technical scheme：A kind of bridge crane electromagnetic lifter angle
Automatic station-keeping system, including air switch, programmable controller, button, switch, frequency converter, motor, electronic compass and gyro
Instrument, the air switch is through the frequency converter and the motor connection；The programmable controller is connected with the air switch,
The electronic compass and the gyroscope are connected with the programmable controller, the output end of the programmable controller and institute
State frequency converter connection.
Further, touch-screen is included, the touch-screen is connected with the programmable controller.
Compared with prior art, the present invention has advantages below：The advantage of gyroscope and electronic compass is simultaneously used in
Bridge crane electromagnetic lifter angle is automatically positioned that there is provided plant not only to be avoided that electromagnetic lifter interference but also can solve initial angle and ask
The scheme of topic.
Brief description of the drawings
Fig. 1 is the circuit control schematic diagram of bridge crane electromagnetic lifter angle automatic station-keeping system of the present invention.
Embodiment
The present invention will be described in detail below in conjunction with the accompanying drawings, and the description of this part is only exemplary and explanatory, should not
There is any restriction effect to protection scope of the present invention.
As shown in figure 1, a kind of bridge crane electromagnetic lifter angle automatic station-keeping system, mainly by air switch QF1, touch
The groups such as screen, programmable controller PLC, button SB1, button SB2, switch SB3, frequency converter, motor M1, electronic compass, gyroscope
Into.
The course of work：Close after air switch QF1, programmable controller PLC is started working, output port Y6 closures, electricity
Sub- compass obtains electric, at this moment reads the angle value θ 1 that the electronic compass being arranged on electromagnetic lifter is exported by PLC 485 port A, B,
Complete to disconnect Y6 after electromagnetic lifter current angle position is read, be also turned on Y7, gyroscope obtains electric work, at this moment gyroscope output angle
Spend for 0 degree；When electromagnetic lifter angle change, gyroscope starts the changing value θ 2 of output angle, and at this moment the angle value of electromagnetic lifter is just
It is θ 1+ θ 2.Assuming that electromagnetic lifter is θ 3 in the angle value parallel to factory building direction, then the angle perpendicular to factory building direction is exactly θ 4
=θ3+90°；When switching SB3 connection input port X2, PLC exports Y1 and analog quantity electric current A0+ by computing, and frequency converter is entered
Row control, and then the rotation of controlled motor, the rotation of motor drives the rotation of electromagnetic lifter, when the direction of electromagnetic lifter is close to parallel factory
During room direction, Y1 is disconnected, and Y2 is connected, decelerating through motor operation, and when electromagnetic lifter is in parallel factory building direction, PLC stops output；Together
Sample reason, when switching SB3 connection input port X3, can just control electromagnetic lifter to be in the direction position of vertical factory building by PLC
Put.
Described above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications also should
It is considered as protection scope of the present invention.
