Compared with the prior art, the position monitoring system has alarming and shutdown protection functions, the operating states of the crane boom and travelling are controlled accurately, the collision between the crane boom and objects nearby can be avoided in the course of work, the hoisting operation safety of the crane can be ensured during cross operation, the operation intensity of drivers is reduced, and the production safety and efficiency are improved greatly.
Description
Technical field
The utility model relates to technical field of industrial automatic control, especially a kind of high pedestal jib crane location monitoring system based on light volume and electronic compass.
Background technology
High pedestal jib crane is shipyard or harbour handling workpiece use, is the important production facilities of shipyard, mainly comprise hoist, luffing, rotation and traveling gear.Rotation and luffing mechanism drive seat type crane arm support to carry out the rotation of horizontal and vertical direction, and traveling gear drives high pedestal jib crane to move along ground rail.When high pedestal jib crane operation, need to rely on driver and ground maneuvers personnel by visual inspection hoisting crane position, by virtue of experience realize 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, employing precision is that GPS location and measuring pulley, photoelectric encoder and the mechanical angle sensor of civilian level monitored the locus of seat type crane arm support, guarantees the production safety of high pedestal jib crane in the time of cross-operation.The problem that prior art exists is: the general >10m of GPS positioning precision degree of civilian level, if improve its precision to m level, need to set up ground base station, the construction cost of ground base station, obviously higher than the cost of high pedestal jib crane control system, has the interference problem of radiocommunication in addition.Measuring pulley and photoelectric encoder are arranged on the driven wheel of rotating mechanism, and cost of equipment and construction cost are high, need the cumulative errors of frequent correction mechanical tolerance and equipment operation, and precision is low, and volume is large, and cannot realize digital signal output.
Summary of the invention
The purpose of this utility model is to design a kind of high pedestal jib crane location monitoring system based on light volume and electronic compass for the deficiencies in the prior art, adopt photoelectric encoder and electronic compass and PLC to form the Control loop of crane arm support Real-Time Monitoring, in the time that jib enters hazardous location, this control loop is reported to the police by PLC or is protected shutdown, the effectively monitoring spatiality of jib and the orbital position of traveling gear, having avoided 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 purpose of this utility model is achieved in that a kind of high pedestal jib crane location monitoring system based on light volume and electronic compass, comprise the high pedestal jib crane that is provided with jib rotation/luffing mechanism and crane travelling gear, jib rotation/luffing mechanism and crane travelling gear connecting drive device, be characterized in that described jib rotation/luffing mechanism is provided with electronic compass; Described crane travelling gear is provided with photoelectric encoder; Described actuating device is provided with transducer drive; Described frequency converter, electronic compass and photoelectric encoder and be provided with touch-screen or the PLC main frame of external industrial computer connects and composes crane control closed loop; Described PLC main frame is provided with collision risk region and warning or the stoppage protection program of crane arm support; in the time that crane arm support enters hazardous location, send and report to the police or send stoppage protection signal to frequency converter by PLC main frame; and dynamically shown by touch-screen or external industrial computer, realize the real-time monitoring of crane arm support and walking.
The utility model compared with prior art has reports to the police and stoppage protection function; the accurately running state of monitoring crane arm support and walking; 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.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Detailed description of the invention
Consult accompanying drawing 1, the utility model is formed by connecting by PLC main frame 1 and the frequency converter 2 that is arranged on electronic compass 1, the photoelectric encoder 6 on high pedestal jib crane 4 and be arranged on actuating device 3, and described electronic compass 5 is arranged on jib rotation/luffing mechanism 41; Described photoelectric encoder 6 is arranged on crane travelling gear 42; Described actuating device 3 is driven by frequency converter 2; Described frequency converter 2, electronic compass 5 and photoelectric encoder 6 connect and compose crane control closed loop with the PLC main frame 1 that is provided with touch-screen or external industrial computer 7; Described PLC main frame 1 is provided with collision risk region and warning or the stoppage protection program of crane arm support; in the time that crane arm support enters hazardous location, send and report to the police or send stoppage protection signal to frequency converter 2 by PLC main frame 1; and dynamically shown by touch-screen or external industrial computer 7, realize the real-time monitoring of crane arm support and walking.
The utility model is to install like this and work: the driver's cab that the PLC main frame 1 that is provided with touch-screen or external industrial computer 7 is arranged on to hoisting crane; Electronic compass 5 is arranged on the jib rotation/luffing mechanism 41 of high pedestal jib crane 4; Photoelectric encoder 6 is arranged on crane travelling gear 42; Frequency converter 2 is arranged on actuating device 3; PLC main frame 1 adopts control cables to be connected with electronic compass 5, photoelectric encoder 6 and frequency converter 2, electronic compass 5 carries out the detection of horizontal and vertical position for LP3300 type three axles to jib rotation/luffing mechanism 41, the jib locus of Real-Time Monitoring high pedestal jib crane 4, photoelectric encoder 6 adopts absolute value to carry out Real-Time Monitoring to the locus of crane travelling gear 42.1, PLC main frame carries out logic judgement according to predefined collision risk region and real-time locus; in the time that the jib of high pedestal jib crane 4 enters hazardous location; send and report to the police or send protection shutdown signal to frequency converter 2 by PLC main frame 1, stopped the operation of jib rotation/luffing mechanism 41 by frequency converter 2 accessory drives 3.Electronic compass 5 is by the data input PLC main frame 1 of Real-Time Monitoring and by touch-screen or external industrial computer 7 locus of Real time dynamic display high pedestal jib crane 4 jibs and the collision risk region of setting, quantize reference system for operating personal provides actv., greatly avoided the jib of maloperation and high pedestal jib crane 4 to enter hazardous location.In the time that the jib of high pedestal jib crane 4 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.
