Abstract
The invention discloses a system for controlling a crane to normally operate in a strong magnetic field. A limiter of a hoisting mechanism is mounted at the tail end of a drum shaft of the hoisting mechanism; a limiter of a trolley operating mechanism is mounted at the tail end of one side of a track of the trolley operating mechanism; a limiter of a cart operating mechanism is mounted at the tail end of one side of a transverse end beam of the cart operating mechanism; a console is mounted in an operating room at the bottom of a main beam of the crane; a central processing unit is mounted in an electrical control room. The system has reliable anti-interference, real-timeliness, high-speed and stability performances. According to the technical scheme, a line is simple, and faults are unlikely to cause and are likely to remove, so that the production efficiency is improved.
Description
Technical field:
The present invention relates to the control system that a kind of hoisting crane high-intensity magnetic field normally runs, the hoisting crane being specially adapted to operation in strong electromagnetic situation uses.
Background technology:
At present, in aluminium industry Electrolytic Workshop, high-intensity magnetic field reaches 600KA, hoisting crane runs in high-intensity magnetic field workshop, be connected with input/output terminal by rigid between crane control desk with each mechanism, transfer instruction controls the operation of each mechanism, under magnetic field environment, Hard link is by the effect in magnetic field, easy generation electric signal interference, affect mechanism normally to work, cause and delay work, the generation caused the accident, moreover, control path is complicated, easy generation fault, reduce production efficiency, because signal line is complicated, instruction is simple, take installing space large, operating personal constantly cannot check the running state of each mechanism of hoisting crane in control cabin, each in-house electric current can not be shown in real time, voltage and rotating speed, cannot get rid of the very first time as broken down, give and produce and safeguard, maintenance brings inconvenience.
Summary of the invention:
Task of the present invention proposes a kind of operating personal can transfer the running state of checking hoisting crane at any time, and circuit is simple, the control system that the hoisting crane high-intensity magnetic field of enhancing productivity normally runs.
Task of the present invention completes like this, the control system that hoisting crane high-intensity magnetic field normally runs, it is characterized in that: lifting mechanism limit limiting device is arranged on lifting mechanism reel the tip of the axis, wheeling mechanism limit limiting device is arranged on end, wheeling mechanism track side, traveling mechanism of the larger traveller limit limiting device is arranged on end, traveling mechanism of the larger traveller horizontal end carriage side, control desk is arranged on bottom crane girder in control cabin, and central process unit is arranged on electrical control indoor.Lifting mechanism, wheeling mechanism, traveling mechanism of the larger traveller, touch-screen display are respectively by bus cable, be bi-directionally connected by bus connector and central process unit output interface, described lifting mechanism limit limiting device, wheeling mechanism limit limiting device, traveling mechanism of the larger traveller limit limiting device are connected with central process unit by bus connector is two-way by bus cable respectively with control desk.The touch-screen that described bus cable is connected is mounted in control cabin and shows in real time.Described bus cable originally has jamproof screen layer with it.
The present invention has following effect: have failure-free anti-interference resistance, real-time, high speed, stability, and the technical program circuit is simple, not easily produces fault, and is easy to get rid of, thus improves production efficiency.
Accompanying drawing illustrates:
Fig. 1 is the block scheme of the technical program; Fig. 2 is the structural representation of the technical program.
Detailed description of the invention:
What the technical program adopted is RG6 bus cable 8, it is a kind of cable carrying screen layer, there is very strong disturbance rejection, under strong magnetic environment, do not produce electric signal interference, guarantee the normal operation of each mechanism, bus cable adopts and is bi-directionally connected with bus connector 11 and each mechanism signal converting, not easily produce fault, and circuit is simple, and easily get rid of after breaking down, thus improve production efficiency.
Specific embodiment as shown in Figure 1, lifting mechanism 1, wheeling mechanism 2, traveling mechanism of the larger traveller 3, touch-screen display 7 are respectively by bus cable, be bi-directionally connected by bus connector and central process unit 4 output interface, and the control accepting central process unit drives each lifting mechanism, wheeling mechanism, traveling mechanism of the larger traveller run, central process unit inputs each mechanism running state, voltage, electric current connect control cabin by bus cable, shows in real time from the touch-screen control cabin, as shown in Figure 2, lifting mechanism limit limiting device is arranged on lifting mechanism 1 reel the tip of the axis, wheeling mechanism limit limiting device is arranged on end, wheeling mechanism 2 track side, traveling mechanism of the larger traveller limit limiting device 10 is arranged on end, traveling mechanism of the larger traveller 3 horizontal end carriage side, control desk to be arranged on bottom crane girder in control cabin, central process unit is arranged on electrical control indoor, described lifting mechanism limit limiting device 6, wheeling mechanism limit limiting device 9, traveling mechanism of the larger traveller limit limiting device 10 is connected with central process unit by bus connector is two-way by bus cable respectively with control desk 5.
During work, operating personal sends startup at control desk 5, run, the command signal such as to stop doing business, central process unit 4 received signal is transferred to lifting mechanism limit limiting device 6, wheeling mechanism limit limiting device 9 and traveling mechanism of the larger traveller limit limiting device 10, central process unit 4 judges the normal backward lifting mechanism 1 of signal, wheeling mechanism 2, traveling mechanism of the larger traveller 3 input control run signal, the running state of each mechanism above, voltage, rotating speed, current failure can input to central process unit 4 at any time, shown in real time by the touch-screen display installed in control cabin 12, operating personal can transfer the running state of checking hoisting crane at any time.
