Detailed description of the invention
Below in conjunction with accompanying drawing and instantiation, the utility model is described in further detail:
It is to install on steel plant's hot rolling flow production line and in not stopping production situation that the utility model is installed, when installation first scale body crossbeam 1 from a side insertion Hot Line between two carrying rollers, after 8 crossbeams are evenly placed, respectively longitudinal girder 9 use bolts and each crossbeam 1 are fixed as one from both sides, scale body installs like this.When same lifting weighing frame 8 is installed, crossbeam from an insertion, assemble again two frame type portal frames 15, hydraulic pressure unit 7 cylinder bodies are fixed on hydraulic base 4, head is connected with universal joint 5, be connected as a single entity by bearing pin 16 and upper mounted plate 6 again, can ensure that like this lifting weighing frame 8 has certain swing buffering range, after fixing, according to production line roller-way height, cushion block 14 is installed, cushion block height is lower than roller-way upper horizontal plane 4cm, adjusting four jiaos of legs spacing 2 adjusts to scale frame in unified levelness, load onto optoelectronic switch 10 for one at scale frame, then at four jiaos, LOAD CELLS 3 is installed, after sensor installation, adjust four jiaos of legs spacing 2 and make it built on stilts 2cm, guarantee that 4 sensors are completely stressed, sensor 3 is connected with instrument 12, hydraulic pressure unit 7 is connected with switch board 11, industrial computer 13 is linked to be net with 11 groups of instrument 12 switch boards, the weighing system software of our company's independent development is installed on industrial computer 13.Its Weighing process is: steel billet is delivered to scale body installation position through rollgang and weighs after part, after optoelectronic switch 10 detects that steel billet puts in place, prompting can be weighed, the installation site of photoelectricity switch guarantees that now steel billet is parked on scale body completely, press the switch of weighing, system is sent the input block of a switching value dry contact signal to weighing system PLC in switch board, roller-way self-locking.After PLC in switch board detects this signal, hydraulic pressure unit 7 starts to rise, when lifting weighing frame 8 rises to after setting height, two lifting weighing frames 8 lift steel billet to leave carrying roller, the weight of steel billet is by lifting weighing frame 8 and scale body the stressed sensor of passing to like this, and sensor is passed to instrument and industrial computer weight signal again.In switch board, PLC sends a mode bit to industrial computer 13 by communication, and industrial computer 13 carries out Weighing after this state being detected.After industrial computer 13 records, send to again another status signal of PLC in switch board by communication, in switch board PLC receive rear control hydraulic pressure unit 7 start decline, lifting weighing frame 8 is fallen after original position, in switch board, the output unit of PLC is exported the dry contact signal system end of this time weighing, steel billet can resume operation, and proceeds the next one circulation of weighing.For adapting to the environment of this high temperature, high dust, high noisy, solve repeatability error large, realize long-time stability object the utility model and done technically following breakthrough:
The carbon brush of motor in workshop, the slip ring of boat car, intercom, the high-intensity magnetic field that high voltage power line more than 50KV produces is flooded with whole workshop, for allowing sensor instrument can normally use under superhigh temperature, strong complex electromagnetic environment, we adopt negative electrode double layer screen technology, the grounding measures that scale body, sensor, instrument, switch board, industrial computer all take resistance to be less than 4 ohm, synchronous signal line adopts double shield, has thoroughly solved this technical barrier.
Hydraulic system adopts superhigh temperature resistant processing, be that hydraulic system inner seal rings all adopts fluorubber, due to the good insulation high-temperature-resistant performance of fluorubber, whole hydraulic system can be born 150 degree high temperature, local and steel billet contact portion can be born thousands of degree high temperature, solves the stationary problem of 4 hydraulic pressure units in serious unbalance loading situation.Even if two the suffered resistance difference of oil cylinder is 20T, equally can meet the requirement of simultaneous retractable.
Bearing unit adopts copper graphite material bearing, in copper cartridge housing, inlays graphite annulus, and because graphite itself has natural high temperature resistant, anti-wear performance, solution working site is high temperature resistant, resistance to large dust, and resistance to super-pressure, resistance to high impact forces, and can realize non-maintaining.
Electric current Anti-surging technology, welding machine in workshop, cable is staggered, has at any time heavy current by sensor, and we adopt Anti-surging insulation technology for this reason, thoroughly ensure that sensor can not broken by heavy current.
Anti-heat expansion cold-shrink technology, due to the installation environment problem of roller-way scale, in its 24 hours, poor the reaching 20 of high and low temperature spent more, noon, scale body can reach degree more than 50 when overheated steel billet, and when cross cold steel billet morning, scale body less than 30 is spent, and scale body deformability amount reaches 2cm left and right, thereby because of the movement of sensor pressure head, sensor is produced to longitudinal force, and then generation roller-way scale non-return-to-zero, jumping figure, the situation that data are inaccurate.Design special pressure head for this situation, to ball bowl on sensor pressure head in different ways, on sensor of scale body, ball bowl adopts ball-bowl type pressure head, other end to adopt the recessed formula pressure head of longitudinal length of particular design, on sensor, steel ball is longitudinally can be with the amount of expanding with heat and contract with cold automatic moving, and can remain that sensor is vertically stressed, the elimination longitudinal force producing of expanding with heat and contract with cold makes the effect of weighing more accurate, more perfect.
Industrial computer is provided with the management software of weighing of our company's independent development, the problems such as the automatic identification of the system that realized to steel billet, tracking, analysis, weighing, whole system has realized intellectuality, unmanned, solve the mutual communication issue of existing system and workshop total system, different brands, different agreement, different modes, realize full application of brake for production line from now on, unmanned, precision has been established technical foundation.
