Description
Technical field
The present invention relates to a kind of jacking system, be especially with and protect top full-automatic lifting system, is a kind of equipment that large-sized object can be made to be elevated the also safe Bao Ding of energy.
Background technology
In Three Gorges Ship Lock annual repairs in 2012, respectively by the miter gate jack-up of Liang Jia unit in charge of construction by more than 850 ton, two of southern six lock heads fan, fall again after having keeped in repair.The lifting of miter gate does not allow to occur any contingency, needs a set of guarantor's ejection device, play stable effect when oil cylinder has fault.A construction party has used five to overlap independently jacking system, and carries out Bao Ding by the mode of traditional manual synchronization.Another family expenses, Chinese Patent Application No.: the mode of 200610019913.3 " multipoint synchronous lifting device and elevating methods thereof ".Although the lifting task completing miter gate that two kinds of modes are all satisfactory.By contrast " multipoint synchronous lifting device and elevating method thereof ", obviously be stepped major step in the application of up-to-date technology, but this apparatus and method also have some shortcomings, it mainly adjusts load thing attitude by the displacement of the displacement pickup of each point, the adjustment of attitude is the value of the height controlling each point by hand, reaches the object controlling attitude, and pose adjustment is by people, large by emotion influence, time-consuming.Error in lifting between each displacement pickup, can make the attitude of load thing change, and causes load thing center of gravity to change, causes the stressed of each jack to change, even produce dangerous hidden danger.In addition, with " multipoint synchronous lifting device and elevating method thereof " with the use of spiral Bao Ding, because volume is large, the structure of lower buttress and upper padding plate, make spiral protect top and can not be placed on miter gate's load-bearing fulcrum, other position can only be supported on, the weak effect of Bao Ding.So the structure of oil cylinder, Bao Ding and a cushion block needs to be optimized design.Use the method in addition, used eight people to rotate spiral Bao Ding, followed by the lifting of hydraulic jack, the top of spiral Bao Ding and load thing is allowed to maintain a certain distance, in case when jack has a fault, spiral is protected top and can be played and support miter gate, keeps its height and stable.The less effect in gap between spiral Bao Ding and load thing is better, but the actual artificial operating clearance of each point is not etc., and what have greatly is many at 20mm.Obvious employment is many, and the weak effect of Bao Ding, therefore the control of Bao Ding also needs to improve.
Summary of the invention
In order to further improve the series of jacking system, the present invention attempts to provide a kind of band to protect top full-automatic lifting system, it can not only the attitude of centering load thing automatically, it is protected ejection device and can also follow up automatically, and the setting gap between spiral Bao Ding and load thing can be kept, guarantee that, when contingency, protect top and can play best firm effect, it is grouped together at oil cylinder, mechanical Bao Ding, upper lower cushion block.
The technical solution adopted for the present invention to solve the technical problems is: top full-automatic lifting system protected by band, comprises mechanics, hydraulic part, electrical control part.Mainly contain three features: the combined mechanical lifting unit of first entirety, lifting unit is by oil cylinder, and mechanical Bao Ding, lower bolster, upper junction plate, motor decelerating mechanism, miniature gears, big gear wheel, screw rod, top board forms, and hydraulic ram is in centre, and there is mechanical Bao Ding at two ends.Hydraulic ram, mechanical Bao Ding and lower bolster are grouped together use; Lower bolster connecting fluid compressing cylinder and mechanical Bao Ding; Upper junction plate connecting fluid compressing cylinder and mechanical Bao Ding; Machinery Bao Ding is made up of screw rod, nut and screw bolt seat, and screw rod inserts in screw bolt seat, and there is negative thread the outer ring of nut, can rotate around screw rod.Motor decelerating mechanism connects miniature gears; The inner ring of big gear wheel has negative thread, can rotate around screw rod, and big gear wheel and nut are same parts; The upper end of screw rod is connected to above top board, and lower end is inserted in screw bolt seat; Top board is placed on above oil cylinder, is connected with screw rod.It two is that top full-automatic lifting system protected by band, keep the full-automatic lifting pattern of attitude, the method of full-automatic lifting is: control system is made up of PLC or computer, touch-screen or telltale, angular transducer, pressure sensor, displacement pickup, oil cylinder working-pressure sensor or oil cylinder working-pressure transmitter, load thing installs an angular transducer, and angular transducer is interim being fixed on a body.Control method is measured the squareness of load thing, by data input control system, adjust the angle that angular transducer will control, and can by this angle zero setting, as the attitude during load thing lifting that will control, the automated manner that load thing keeps same attitude to be elevated is, the lifting unit being provided with displacement pickup is allowed to be elevated, in lifting process, the data of load thing change of pitch angle are passed to PLC by angular transducer, by contrast computing, the lifting unit of the X-axis that PLC instruction is adjacent and Y-axis is followed the tracks of, it can be electrodeless variable that rate of following is directly proportional with income signal, ceaselessly follow the tracks of operation, reach the object keeping same attitude lifting load thing.Its three be mechanical type from motion tracking Bao Ding, the method for full automaticity Bao Ding is: control system is made up of PLC or computer, touch-screen or telltale, sensor.Mechanical type is from motion tracking Bao Ding, the method of full automaticity Bao Ding is: Stroke Displacement Transducer is arranged on any one lifting unit, minute displacement sensor or pressure sensor is provided with between big gear wheel and screw bolt seat, screw rod up-and-down movement in screw bolt seat is driven with oil cylinder lifting, change in displacement supplemental characteristic passes to PLC, be greater than or less than setting when putting, will by contrast computing, the corresponding motor decelerating mechanism of PLC instruction, Drive pinion drives big gear wheel motion, nut in big gear wheel moves up and down in screw rod, ceaselessly follow the tracks of operation, reach the setting gap of retention nut and screw bolt seat, play the object from motion tracking Bao Ding in lifting process, after load thing is elevated to predetermined stroke, provide a locking signal again, eliminate the gap of nut and screw bolt seat, reach after shutdown can the object of Bao Ding for a long time.
The invention has the beneficial effects as follows, top full-automatic lifting system protected by band, first combined mechanical lifting unit, it two is keep the full-automatic lifting pattern of attitude, and miter gate's body installs an angular transducer, allows the lifting unit lifting being provided with displacement pickup, the data of miter gate's change of pitch angle are passed to PLC by angular transducer, by contrast computing, the lifting unit of the X-axis that PLC instruction is adjacent and Y-axis is followed the tracks of, and reaches the object keeping same attitude lifting miter gate.It three is that mechanical type is from motion tracking Bao Ding, displacement pickup is provided with between big gear wheel and screw bolt seat, screw rod up-and-down movement in screw bolt seat is driven with oil cylinder lifting, displacement pickup is greater than or less than setting when putting, data are passed to PLC, by contrast computing, the corresponding motor decelerating mechanism of PLC instruction, Drive pinion drives big gear wheel motion, nut in big gear wheel moves up and down in screw rod, reach the setting gap of retention nut and screw bolt seat, play the object from motion tracking Bao Ding in lifting process.
