In preferred forms, SIEMENS PLC 300 selected by controller, it is chief component in control device, can require to carry out parameter designing according to user, can store therein actuating logic computing, sequential control, regularly, counting and the operational order such as arithmetic operator, and by input and output, production control process.Industrial computer adopts Siemens industrial computer, and it has stronger anti-harsh working environment ability, can in industrial environment 24 hours reliability services incessantly, Information Security highly makes system downtime minimize, and adds system availability.Hydraulic operation device 5 adopts hydraulic cylinder, is mainly to perform original paper.Hydraulic energy is changed into mechanical energy, does the hydraulic actuator of straight reciprocating motion by hydraulic cylinder.Servo valve 7 adoption rate servo valve, its valve port can open any one aperture as required, controls the size by flow thus.The reciprocal speed action control of hydraulic cylinder is carried out by the aperture size of controller control ratio servo valve.Hydraulic Station is hydraulic system chief component.Hydraulic Station rotates the hydraulic power source device be made up of hydraulic pump, drive motor, fuel tank, overflow valve etc. or the hydraulic means driven by motor oil pump comprising control valve, pump is bought oil after oil suction from fuel tank, be the pressure energy of hydraulic oil by changes mechanical energy, in the oil cylinder being transferred to hydraulic machinery through external pipeline after hydraulic oil is achieved direction, pressure, Flow-rate adjustment by integrated package (or valve combination) by hydraulic valve or oil motor, thus control the speed of the conversion in hydraulic cylinder direction, the size of strength and speed, promote the acting of various hydraulic machinery.Pressure is converted to the sensor that the signal of telecommunication exports by pressure sensor 9.It highly sensitive, precision good, can measure the accuracy of 0.1%.Displacement transducer 8 can monitor hydraulic cylinder misalignment in real time.Displacement transducer 8 have easily realize digitlization, precision is high, antijamming capability is strong, do not have artificial error in reading, easy for installation, use the advantages such as reliable.Oil filter adopts high-pressure filter, and the protection of high-pressure filter, can filter the oil circuit of whole hydraulic system, is that cylinder body and proportional servo valve better work.If high-pressure filter blocks, have instruction of reporting to the police.
The control procedure that pre-tensioned rail plate synchronous tension puts a control system mainly comprises: zero point alignment, track plates 6 add, put a front prestretching, track plates 6 is put.
1. a zero point alignment (add before pre-stretch-draw) of crossbeam:
In order to prevent prestressing force silk from deviating from when stretch-draw, pressing plate is manually put into stretch-drawing beam fixed position after installing and all completing by prestressing force silk; After installation prestressing force silk after initial tensioning 20%, stretch-draw computer must be operated by technical staff; After stretch-draw completes 20%, whether hand inspection has stripped thread, fracture or loosening phenomenon, if find necessary reporting techniques person, after handling it, can carry out lower to operation.Zero point alignment is controlled by computer, shows stretching force and the displacement of each jack above display screen.Jack ejects according to the displacement set in advance, locks with collar nut.
As requested crossbeam position is adjusted, with coordinating of controller, hydraulic cylinder is located by industrial computer accurately, reach accurate location.The zero point alignment of crossbeam carries out artificial setting when only needing first time to use, and directly access history data can carry out zero point alignment when reusing.
2. track plates adds:
After crossbeam zero point alignment, according to the setting parameter request of rail plate tension being carried out to setting to rail plate tension numerical value, only need to click at target value place and to carry out input digital.Stretch-draw 100%, is operated by professional and technical personnel, notes the change of compressor wire in stretching process, and whether hand inspection has stripped thread, fracture or loosening phenomenon, if find necessary reporting techniques person, after handling it, can carry out lower to operation.
3. add a process and be divided into two processes:
(1) synchronous shift stretch-draw: front 80 percent of the whole process of stretch-draw is displacement synchronous, and ensures that the displacement difference of two hydraulic cylinders is lower than two millimeters.
(2) with power stretch-draw: rear 20 percent of the whole process of stretch-draw is same power stretch-draw, should not exceed limit value with the numerical difference of two hydraulic cylinders in power stretching process.
Add Zhang Qianke according to field requirement carry out synchronous shift displacement step size settings, with the setting of power step-length and the setting of time.Can carry out after set-up procedure completes adding and open.Single-beam stretch-draw can be carried out during stretch-draw and also can carry out four beams with drawing.
4. put a front prestretching:
Because the duration in maintenance processes is longer, in order to better ensure the pulling force of steel wire, adopt physics locked.A prestretching before putting is exactly convenient unblock, for putting of next step provides better working environment.Putting a prestretching will keep pulling force steadily not occur concussion situation, can arrive appointment numerical value accurately, can unlock easily.When putting prestretching, hydraulic cylinder change in displacement is less.Because displacement is less when the characteristic of putting a prestretching puts prestretching, so relative skill requires higher, must guarantee to reach accurately and rapidly when putting prestretching and put a pre-pull-up values.Guarantee to put prestretching stability, an accuracy.
5. put a process:
Putting a process is the whole showdown stage re-packed in process, is also the highest stage of technical requirement.In this process, arbitrarily can adjust the step-length of putting and opening and put a time.Four of side hydraulic cylinders can be made to carry out Synchronous Radio when to put to open, also can ensure that eight hydraulic cylinders carry out Synchronous Radio and open simultaneously.Put in a process can reach steadily, arrive accurately put completely complete.
Above an embodiment of the invention has been described in detail, but described content being only the preferred embodiment of the invention, the practical range for limiting the invention can not being considered to.All equalization changes done according to the invention application range with improve, within the patent covering scope that still all should belong to the invention.
