Description
Technical field
The present invention relates to technical field of industrial automatic control, especially a kind of stationary crane hangs row of horizontal control monitor unit.
Background technology
Stationary crane is harbour handling workpiece use, and be the important production facilities of shipyard, its structure is fixed mast formula, and principal organ is lifting mechanism and luffing mechanism, and each mechanism is wire rope pulley group drive system.The type hoisting crane is when handling workpiece, due to the cumulative errors that mechanical tolerance and motor run, the steel rope folding and unfolding speed of two groups of suspension hooks is asynchronous, the situation of the very easily large-scale suspender inclination such as the row of hanging, electromagnetic suspended beam, cause workpiece unstability, bring certain potential safety hazard to hoisting operation.So during lifting run-off the straight state, need to rely on driver's visual inspection, manually the balance of adjustment suspender, due to the no quantization data of manual observation, manual regulation is without reference coordinate, so that the safety misadventure of hoisting crane takes place frequently.Therefore need to provide a set of safe and reliable suspender adjustment System to monitor the horizontality that hoisting crane hangs row, simultaneously and crane mainframe control system chain, avoid suspender inclination unstability, minimizing potential safety hazard.
Summary of the invention
The object of the invention is to design a kind of stationary crane for the deficiencies in the prior art and hang row of horizontal control monitor unit; horizontal measurement and control instrument and angular transducer and crane mainframe PLC system is adopted to form the level control loops road of suspender; this control loop can preset suspender range of deflection angles in output alarm signal; the unequal protection function of suspender is started by PLC; automatic or manual is selected to carry out the balanced adjustment of suspender; the horizontality of effective control suspender; guarantee to lift by crane safe in operation; structure is simple; easy to operate
The object of the present invention is achieved like this: a kind of stationary crane hangs row of horizontal control monitor unit, be characterized in that this horizontal monitoring device connects into hoisting crane by horizontal measurement and control instrument and crane mainframe PLC system and angular transducer and hangs row of horizontal Control loop, described crane mainframe PLC system is provided with the row of hanging linked with crane hoisting and luffing mechanism and tilts automatic adjustment programme; Described horizontal measurement and control instrument is provided with the display of the row's of hanging angle of inclination and the autoalarm signal of the row's of hanging inclination; Horizontal measurement and control instrument is monitored by the horizontality of angular transducer to the row of hanging and is exported the alerting signal of suspender inclination to crane mainframe PLC system, and crane mainframe PLC system starts automatic or manual according to the deflection angle of the row of hanging and controls the balance that hoisting crane hangs row.
Described horizontal measurement and control instrument and angular transducer adopt RFDC to be connected.
Described horizontal measurement and control instrument and crane mainframe PLC system adopt control cables to be connected.
What the row of hanging linked with crane hoisting and luffing mechanism that described automatic adjustment is preset by crane mainframe PLC system tilted that automatic adjustment programme carries out hangs row of horizontal adjustment.
Described be manually adjusted to driver according to the deflection angle that horizontal measurement and control instrument shows carry out manually operated hang row of horizontal adjustment.
It is simple that the present invention compared with prior art has structure, and equipment maintenance cost is low, avoids suspender inclination unstability, the horizontality of effective control suspender, reduces potential safety hazard, improves crane control level, guarantee to lift by crane safe in operation, enhance productivity, reduce driver's operation intensity further.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention
Detailed description of the invention
Accompanying drawings 1, the present invention connects into hoisting crane by horizontal measurement and control instrument 2 with crane mainframe PLC system 1 and angular transducer 3 and hangs row of horizontal Control loop, and described crane mainframe PLC system 1 is provided with the row of hanging linked with crane hoisting and luffing mechanism and tilts automatic adjustment programme; Described horizontal measurement and control instrument 2 is provided with the display of the row's of hanging deflection angle and the autoalarm signal of the row's of hanging inclination; Horizontal measurement and control instrument 2 is monitored by the horizontality of angular transducer 3 to the row of hanging and is exported the alerting signal of suspender inclination to crane mainframe PLC system 1, and crane mainframe PLC system 1 starts automatic or manual according to the deflection angle of the row of hanging and controls the horizontality that hoisting crane hangs row.
The present invention installs and work like this: crane mainframe PLC system 1 and horizontal measurement and control instrument 2 are arranged on stationary crane 4 operator's compartment; Angular transducer 3 is arranged on hoisting crane and hangs on row; Angular transducer 3 adopts RFDC to be connected with horizontal measurement and control instrument 2; Horizontal measurement and control instrument 2 adopts control cables to be connected with crane mainframe PLC system 1.Horizontal measurement and control instrument 2 and crane mainframe PLC system 1 and angular transducer 3 connect into the level control loops road of suspender.Horizontal measurement and control instrument 2 output alarm signal show the deflection angle of suspender in the suspender range of deflection angles preset; crane mainframe PLC system 1 starts suspender unequal protection function according to the alerting signal that horizontal measurement and control instrument 2 exports, and selects automatic or manual to carry out the balanced adjustment of suspender.As manual adjustment modes is: the deflection angle that driver shows according to horizontal measurement and control instrument 2, regulate suspender within the scope of normal dip.According to self-regulation mode, crane mainframe PLC system 1 is carried out the balanced adjustment of suspender automatically by pre-set programs.The measuring and control data of horizontal measurement and control instrument 2 is regulate the horizontality of suspender to provide actv. to quantize reference system, avoids maloperation and suspender enters dangerous angled section.The deflection angle of buzzerphone alarm apparatus and Dynamic Announce suspender also can be set in driver's cab, remind driver's suspender to enter hazardous location, carry out the horizontal adjustment operation of suspender, guarantee to lift by crane safe in operation, reduce driver's operation intensity.
More than just the present invention is further illustrated, and be not used to limit this patent, allly implements for the present invention's equivalence, within the right that all should be contained in this patent.
