Abstract
The invention belongs to the technical field of anti-misalignment appliances for walking beams and particularly relates to an anti-misalignment control unit for a walking beam. The anti-misalignment control unit comprises an oil tank, a hydraulic pump, synchronous cylinders and the walking beam. The anti-misalignment control unit is characterized in that a displacement sensor is fixedly connected to moving pistons of the synchronous cylinders, and the signal output end of the displacement sensor is connected with a programmable controller. The anti-misalignment control unit has the advantages that during production, in case of two synchronous cylinders being asynchronous, an anti-misalignment control program is taken immediately, field staff is reminded of taking a checkout, problems found are solved in time, the influence of misalignment of the walking beam upon emergency repair of equipment is avoided, and production efficiency is improved.
Description
Technical field
The invention belongs to step rate Anti-dislocation apparatus technical field, particularly relate to a kind of step rate Anti-dislocation control device.
Background technology
At present, in the existing hot rolled seamless steel tube unit of our factory, walking-beam furnace plays vital effect to the quality improving seamless steel pipe product, steel pipe movement in walking-beam furnace has been come by step rate, the movement locus of step rate is that rising-advance-four elemental motions that decline-retreat form a circulation, and each action has been come by two synchronous fuel tanks synchronous workings.And step rate is in motion process, can misplaces because of the asynchronous furnace bottom that causes during two synchronous fuel tank work, cause mechanical jam, make step rate deformed damaged, cause equipment to rush to repair, affect hot rolling and produce.
Summary of the invention
The object of the invention is to solve above-described technical problem, provide one to prevent because of asynchronous during two synchronous fuel tank work, cause step rate deformed damaged, the step rate Anti-dislocation control device that can enhance productivity, its technical scheme is as follows:
Step rate Anti-dislocation control device, comprises fuel tank, hydraulic pump, synchronous fuel tank and step rate, it is characterized in that, the movable piston of described synchronous fuel tank is fixed with displacement transducer, and the signal output part of described displacement transducer is connected with Programmable Logic Controller.
Preferred embodiment is, described displacement transducer is connected with Programmable Logic Controller by four-core shielded cable.
Preferred embodiment is, described Programmable Logic Controller is Siemens S7-300 controller.
Step rate Anti-dislocation control device provided by the invention, displacement transducer and Programmable Logic Controller, output alarm signal, Field Force is reminded to check, pinpoint the problems and process in time, PLC performs Anti-dislocation control program immediately simultaneously, stops the oil cylinder that displacement is large, allows the relatively little oil cylinder of displacement work on.
The present invention further uses four-core shielded cable, and the transmission of signal can be made to be interfered and to shield, thus makes Signal transmissions more accurately, in time.
The present invention further adopts Siemens S7-300 controller.Can well write Anti-dislocation control program.
The beneficial effect of the present invention's design is: in process of production, as long as two synchronous fuel tanks are asynchronous, perform Anti-dislocation control program immediately, warning reminding Field Force checks simultaneously, pinpoint the problems and process in time, avoid step rate to misplace and cause equipment to rush to repair the thing generation of impact production, enhance productivity.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention.
Detailed description of the invention
Embodiment is illustrated below in conjunction with Fig. 1:
As shown in Figure 1, step rate Anti-dislocation control device, comprises fuel tank 1, hydraulic pump 2, synchronous fuel tank 3 and step rate 4, it is characterized in that, the movable piston of described synchronous fuel tank 3 is fixed with displacement transducer 5, and the signal output part of described displacement transducer 5 is connected with Programmable Logic Controller 6.Described displacement transducer is connected with Programmable Logic Controller by four-core shielded cable.Described Programmable Logic Controller is Siemens S7-300 controller.
Two synchronous fuel tanks install two displacement transducers, Siemens S7-300 controllers.During the displacement sensor of installation position, the piston rod of two synchronous fuel tanks to punch tapping, displacement transducer is fixed on the piston rod, by four-core shielded cable, the output signal of displacement transducer is received on Siemens S7-300 controller, be convenient to the shift value that controller gathers two displacement transducers, thus realize the startup and the stopping that being controlled single oil cylinder by two displacements, avoid step rate because of two asynchronous situation generations causing step rate dislocation distortion and damage of synchronous fuel tank.
When concrete use, during synchronous fuel tank movable, the output signal of displacement transducer is sent to on-the-spot Programmable Logic Controller and (is called for short: PLC); By writing protection and alert program in the programmable controller, PLC carries out real-time monitoring to the signal of the displacement transducer of collection in worksite, (be judged to be that two synchronous fuel tanks are asynchronous) when detecting that the displacement phase difference of two displacement transducers is greater than allowable error, output alarm signal immediately, remind Field Force to check, process in time of pinpointing the problems, PLC performs Anti-dislocation control program immediately simultaneously, stop the oil cylinder that displacement is large, allow the relatively little oil cylinder of displacement work on; When system detects that two synchronous fuel tanks are in the error range allowed again, two oil cylinders work on, and quit work together, wait for next do action after arrival is spacing.
