Below in conjunction with the specific embodiment and accompanying drawing, the utility model is described in further detail.
Description of drawings
Fig. 1 is the example structure scheme drawing.
The specific embodiment
The Lift-on/Lift-off System of the long chi rail of lifting of the present utility model, comprise at least 2 traverse cranies, displacement detector, displacement detector are arranged on the transmission position of the dolly of traverse crane and the actuating unit that hoists, and the control system of each traverse crane is linked to be network by communication link.The displacement signal detector is selected absolute value encoder for use, be used for detecting dolly, the operation displacement of the actuating unit that hoists, and with the control system of signal feedback to each traverse crane, thereby realization is to the operation displacement real-time tracking of the dolly of each traverse crane, the actuating unit that hoists.Because having, the multipoint interface network do not need extra hardware and software, and realize simple advantage, so the control system of each traverse crane constitutes the multipoint interface network by communication link, communication link is selected wire link for use, helps to guarantee synchronized operation and the reliability thereof of each traverse crane when the long chi rail of lifting.The control system of each traverse crane communicates with dolly frequency converter, the actuating unit frequency converter that hoists, dolly absolute value encoder, the actuating unit absolute value encoder that hoists, read-out by remote modular I/O station.The remote modular I/O station of each traverse crane is arranged on the driver's cab of traverse crane, control system is stood to sending controling instructions such as dolly, the actuating units that hoists by remote modular I/O, reduced the connecting cable of operator's compartment to electric panel room, reduce malfunctioning node, improved the stability of Lift-on/Lift-off System.Read-out is arranged on operator's compartment, is used to show running state, the position of current each traverse crane, whether has information such as fault, and helping chaufeur better carries out proper operation, improves the running precision of lifting operation.Depend on the rail length that traverse crane can lift when lifting long chi rail and with the platform number of traverse crane, and the length of long chi rail, such as, the traverse crane of 50 meters rail of 2 liftings is also used the lifting that can realize 100 meters long chi rail, and the traverse cranies of 3 lifting 25 rail are also with the lifting that can realize 100 meters long chi rail.Along with the improvement of Rail Production technology from now on, for the long chi rail more than 100 meters, as long as the traverse crane platform number of corresponding increase and usefulness can be realized the lifting to the long chi rail more than 100 meters.
Embodiment
By 3 liftings that lift two 20 tons of double hook traverse cranies realizations of 25 meters rail to 100 meters long chi rail, 3 traverse cranies are distinguished called after traverse crane a, traverse crane b, traverse crane c.Referring to Fig. 1, at the transmission position of the dolly of 3 traverse cranies and the actuating unit that hoists ELTRA profibus bus is set respectively and changes absolute value encoder more as displacement detector, the control system of traverse crane a, traverse crane b, traverse crane c links to each other by two core shielded twisted pairs, constitute three looped network multipoint interface networks (MPI) communication system, can carry out data exchange arbitrarily between three control system.The control system of each traverse crane communicates by far module ET200 and dolly frequency converter, the actuating unit frequency converter that hoists, dolly absolute value encoder, the actuating unit absolute value encoder that hoists, read-out.The far module ET200 of each traverse crane is arranged on the driver's cab of traverse crane, control system by far module ET200 to sending controling instructions such as dolly, the actuating units that hoists.The read-out of each traverse crane is touch display screen---TP170A, also is arranged on operator's compartment.
The working process of realizing 100 meters long chi rail of lifting is: choose the main car of traverse crane b for three traverse crane operations of control from traverse crane a, traverse crane b, traverse crane c, traverse crane b, traverse crane c are from car, and main car is to send corresponding operating instruction from car.From car with its dolly absolute value encoder, the operation displacement signal that the actuating unit absolute value encoder that hoists detects sends to the control system of main car by the MPI network, the control system of main car again will from the operation displacement signal of car respectively with the dolly of main car, the operation displacement signal of actuating unit of hoisting compares asks poor, carry out calculation process, and compensating signal is transferred to control system from car by the MPI network, from the control system of car again compensating signal is sent to dolly by the far module ET200 on it and/or the frequency converter of the actuating unit that hoists on additional given on, thereby make dolly and/or the actuating unit that hoists carries out speedup or runs slowly, promptly when leading from the dolly of car and/or the actuating unit that hoists or fall behind and during main car, to slowing down from the dolly of car and/or the actuating unit that hoists or quickening, hoist to guarantee three traverse cranies, trolley travelling is synchronous.The just commentaries on classics of the dolly and the actuating unit motor that hoists, counter-rotating respectively are made as fourth gear, and each grade speed is set at 10%, 25%, 50%, 100% of command speed respectively.Speed ratio is 1:10.Adjusting speed accuracy is very high, and high-speed smooth, low cruise for a long time, and accuracy of positioning and operating efficiency height are to reduce traverse crane hook beam in starting, the inconsistent problem of the glancing impact amplitude of oscillation.
For ease of driver's operation, the mode to each traverse crane on the touch display screen curtain of operator's compartment setting realizes by select switch, is used to select the mode of traverse crane: main car, from car, bicycle.When three traverse cranies and 100 meters long chi rail of car operation lifting, the select switch of traverse crane b is switched to main car position, the select switch of traverse crane a, traverse crane c switches to from the car position, and chaufeur is the operation of all traverse cranies of may command at the bridge operation of main car (traverse crane b) directly.Five grades of operand select switches are housed in the operator's compartment of traverse crane b: " 1+2 ", " 2 ", " 1+2+3 ", " 1+3 ", " 3 ", switch gear and combination as shown in the table:
| The traverse crane numbering of traverse crane b control | The switch gear | Combination |
| a | 0 | 1 |
| a+b | 1 | 1+2 |
| a+b+c | 2 | 1+2+3 |
| a+b | 3 | 2+3 |
| c | 4 | 3 |
These five grades of operand select switches are only effective during as main car mode at traverse crane." 1+2 ", " 2 ", " 1+3 ", " 3 " are traverse crane b separately to a certain control from car, and " 1+2+3 " controls traverse crane a, traverse crane c simultaneously for traverse crane, have realized three cars, one point operation.If when needing 25 meters rail of handling, bonded assembly two core shielded twisted pairs between the control system of traverse crane a, traverse crane b, traverse crane c to be removed, the mode of each traverse crane switches to bicycle and gets final product.
