Abstract
The invention discloses a fixed crane boom monitoring system which comprises a crane boom driven by a motor and is characterized in that an electronic compass is arranged on the crane boom; the motor is provided with a frequency converter for driving; the electronic compass and the frequency converter are connected with a PLC (Programmable Logic Controller) host machine which is provided with a touch screen or externally connected with an industrial personal computer so as to form a control closed loop of the crane boom; the PLC host machine is provided with a crane boom collision danger area and a warning or shutdown protection program; and when the crane boom enters the danger area, the PLC host machine is used for sending an alarm or sending a shutdown protection signal to the frequency converter so as to realize real-time monitoring on the crane boom. Compared with the prior art, the fixed crane boom monitoring system disclosed by the invention has warning and shutdown protection functions and can be used for precisely monitoring the operating state of the crane boom, so that the boom is prevented from having collision with surrounding objects during the working process, the operation safety in lifting of the crane during cross-operation is guaranteed, the working intensity of a driver is reduced, the production safety and efficiency are greatly improved.
Description
Technical field
The present invention relates to technical field of industrial automatic control, especially a kind of stationary crane jib monitored control system.
Background technology
Stationary crane is that shipyard or harbour handling workpiece are used, it is the important production facilities of shipyard, mainly comprise hoist, luffing and rotating mechanism, the rotating mechanism of stationary crane and luffing mechanism drive its jib, can carry out the rotation of horizontal direction and vertical direction.Stationary crane, in the time of operation, need to rely on driver and ground maneuvers personnel visual inspection arm support position, by virtue of experience realizes early warning, and manual observation is without quantized data, manual regulation is without reference coordinate, processing ease generation deviation, so that the safety misadventure of hoisting crane takes place frequently.The density of equipment of factory increases year by year now, stationary crane driving surface mostly is cross-operation, and jib in the course of the work easy and periphery object generation wiping touches, and gently collision equipment causes workpiece unstability, heavy cause life casualty accident, bring certain potential safety hazard to hoisting operation.
At present, adopt measuring pulley, photoelectric encoder and mechanical angle sensor to monitor the locus of stationary crane jib, guarantee the safety in production of stationary crane in the time of cross-operation.The problem that prior art exists is: cost of equipment and construction cost are high, needs the cumulative errors of frequent correction mechanical tolerance and equipment operation, and precision is low, and volume is large, cannot realize digital signal output.
Summary of the invention
The object of the invention is to design a kind of stationary crane jib monitored control system for the deficiencies in the prior art, adopt the Control loop of PLC connecting electronic compass and frequency converter composition Real-Time Monitoring crane arm support, in the time that jib enters hazardous location, this control loop is reported to the police by PLC or is protected shutdown, the effectively spatiality of monitoring jib, having avoided greatly jib to occur to wipe with periphery object in the course of the work touches, guarantee the lifting safe in operation of hoisting crane in the time of cross-operation, simple in structure, easy to operate, reduce driver's operation intensity, production safety and efficiency improve greatly.
The object of the present invention is achieved like this: a kind of stationary crane jib monitored control system, comprise by motor-driven crane arm support, and be characterized in that described crane arm support is provided with electronic compass; Described motor is provided with transducer drive; Described electronic compass and frequency converter and be provided with touch-screen or the PLC main frame of external industrial computer connects and composes the Control loop of crane arm support; Described PLC main frame is provided with crane arm support collision risk region and warning or stoppage protection program, in the time that crane arm support enters hazardous location, is sent and is reported to the police or send stoppage protection signal to frequency converter by PLC main frame, realizes the real-time monitoring of crane arm support.
The present invention compared with prior art has warning and stoppage protection function; the accurately running state of monitoring crane arm support; avoiding jib to occur to wipe with periphery object in the course of the work touches; guarantee the lifting safe in operation of hoisting crane in the time of cross-operation; reduce driver's operation intensity, production safety and efficiency improve greatly.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The specific embodiment
Consult accompanying drawing 1, the present invention is formed by connecting with being arranged on the electronic compass 1 on crane arm support 6 and the frequency converter 4 being arranged on motor 5 by PLC main frame 2, and described motor 5 is driven by frequency converter 4; Described electronic compass 1 and frequency converter 4 and the PLC main frame 2 that is provided with touch-screen or external industrial computer 3 connect to form the Control loop of crane arm support 6; Described PLC main frame 2 is provided with crane arm support 1 collision risk region and warning or stoppage protection program; in the time that crane arm support 6 enters hazardous location, send and report to the police or send stoppage protection signal to frequency converter 4 by PLC main frame 2, realize the real-time monitoring of crane arm support 6.
The present invention installs and work like this: the driver's cab that the PLC main frame 2 that is provided with touch-screen or external industrial computer 3 is arranged on to hoisting crane, electronic compass 1 is arranged on the crane arm support 6 being driven by motor 5, and frequency converter 4 is arranged on motor 5, PLC main frame 2 adopts control cables to be connected with electronic compass 1 and frequency converter 4, electronic compass 1 detects for the rotating mechanism of LP3300 type three axles to crane arm support 6 and luffing mechanism carry out horizontal and vertical position, the locus of Real-Time Monitoring crane arm support 6, 2, PLC main frame carries out logic judgement according to predefined collision risk region and real-time locus, in the time that crane arm support 6 enters hazardous location, send and report to the police or send protection shutdown signal to frequency converter 4 by PLC main frame 2, controlling by frequency converter 4 rotating mechanism and the luffing mechanism that motor 5 stops crane arm support 6 moves.Electronic compass 1 is by the data input PLC main frame 2 of Real-Time Monitoring and by touch-screen or the locus of external industrial computer 3 Real time dynamic display crane arm supports 6 and the collision risk region of setting, quantize reference system for operating personal provides actv., greatly avoided maloperation and crane arm support 6 to enter hazardous location.In the time that crane arm support 6 enters hazardous location, the buzzerphone alarm apparatus arranging in driver's cab and dynamically demonstration, remind driver to carry out operation adjustment in time, guarantees to lift by crane safe in operation, reduces driver's operation intensity.
More than just the present invention is further illustrated, and not in order to limit this patent, all is the present invention's equivalence enforcement, within all should being contained in the claim scope of this patent.
