Description
Technical field
The present invention relates to a kind of control system, specifically a kind of frequency conversion band bypass crane electrical apparatus control system.
Background technology
In existing commercial production and other activities, widely, but existing crane is before completing in the application of crane
The electric current that row, retrogressing, the rising of lifting rope, decline and the work process such as spacing need a large amount of cables to introduce is powered, due to
Cable quantity is big, weight is big, and girder is provided with multiple steel construction to hold cable, has the most significantly increased the weight of the weight of crane
Amount, causes the waste of electric energy, and fault rate is high.
Summary of the invention
It is an object of the invention to provide a kind of frequency conversion band bypass crane electrical apparatus control system, to solve above-mentioned background skill
The problem proposed in art.
For achieving the above object, the present invention provides following technical scheme:
A kind of frequency conversion band bypass crane electrical apparatus control system is little including hoist converter, B of A trolley travelling converter, A dolly
Car runs converter, B dolly hoists converter, cart runs converter and standby variable frequency device, described A trolley travelling frequency conversion
Device, A dolly hoist converter, the cart of converter, B trolley travelling converter, B dolly that hoist runs converter and standby variable frequency
Device is all by PLC control.
As the further scheme of the present invention: described PLC uses SIEMENS PLC controller.
As the present invention further scheme: described A trolley travelling converter, A dolly hoist converter, B dolly fortune
Hoist converter, cart of row converter, B dolly is run converter and standby variable frequency device and is all connected by feedback of status module and bear
Carry.
Compared with prior art, the invention has the beneficial effects as follows: the present invention can stablize, realize crane frequency conversion control reliably
System, each direction arranges two gears, it is achieved the most adjustable, meets various production needs, the frequency control side of employing
Formula to ensure that the speed governing of each mechanism can quickly be carried out undisturbed；Configuration standby variable frequency device, when event occurs in certain mechanism's converter
Barrier or damage, standby variable frequency device manually switches and comes into operation, it is ensured that crane Emergency use；Employing SIEMENS PLC is concentrated
Control, institute's limited location, transship, the protection such as conversion, by PLC centralized Control, it is ensured that the safe operation of complete machine；Apolegamy high-quality
Siemens's components and parts, it is ensured that its functional reliability, reduce maintenance.
Accompanying drawing explanation
Fig. 1 is the structural representation of frequency conversion band bypass crane electrical apparatus control system.
Detailed description of the invention

Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under not making creative work premise
Embodiment, broadly falls into the scope of protection of the invention.
Refer to Fig. 1, in the embodiment of the present invention, a kind of frequency conversion band bypass crane electrical apparatus control system, transport including A dolly
Row converter, A dolly hoist converter, the cart of converter, B trolley travelling converter, B dolly that hoist runs converter and standby
With converter, described A trolley travelling converter, A dolly hoist converter, B trolley travelling converter, B dolly hoist converter,
Cart runs converter and standby variable frequency device all by PLC control；Described PLC uses SIEMENS PLC control
Device processed；Hoist converter, B trolley travelling converter, B dolly of described A trolley travelling converter, A dolly hoists converter, cart
Run converter and standby variable frequency device all connects load by feedback of status module.
The present invention: (1), crane VFC can be realized stable, reliably.Each direction arranges two gears, it is achieved
Fast the most adjustable, meet various production needs.
(2), the frequency control way used to ensure that the speed governing of each mechanism can quickly be carried out undisturbed；
(3), standby variable frequency device is configured, when certain mechanism's converter breaks down or damages, and standby variable frequency device manually switches throwing
Enter to use, it is ensured that crane Emergency use.
(4), use SIEMENS PLC centralized Control, institute's limited location, transship, the protection such as conversion, by PLC centralized Control, protect
Demonstrate,prove the safe operation of complete machine.
(5), match Siemens's components and parts of high-quality, it is ensured that its functional reliability, reduce maintenance.
It is obvious to a person skilled in the art that the invention is not restricted to the details of above-mentioned one exemplary embodiment, Er Qie
In the case of the spirit or essential attributes of the present invention, it is possible to realize the present invention in other specific forms.Therefore, no matter
From the point of view of which point, all should regard embodiment as exemplary, and be nonrestrictive, the scope of the present invention is by appended power
Profit requires rather than described above limits, it is intended that all by fall in the implication of equivalency and scope of claim
Change is included in the present invention.Should not be considered as limiting involved claim by any reference in claim.
Although moreover, it will be appreciated that this specification is been described by according to embodiment, but the most each embodiment only wraps
Containing an independent technical scheme, this narrating mode of description is only that for clarity sake those skilled in the art should
Description can also be formed those skilled in the art through appropriately combined as an entirety, the technical scheme in each embodiment
May be appreciated other embodiments.
