Description
Technical field
The present invention relates to a kind of detecting device, especially relate to a kind of hot finisher kink position detecting device, belong to hot finisher equipment technical field.
Background technology
Finishing mill kink assembly is arranged between adjacent two frames of finishing mill, is used for absorbing between two frames band steel bushing amount and realizes tension force control.
Kink position detecting device is for detecting the position of kink assembly and by measurement feedback to kink closed loop controller to calculate the velocity compensation amount to corresponding frame, each gantry speed is made to be able to adjust in time and exactly, make between adjacent rack, to realize suitable little set amount mild tension condition, it is ensured that the facility of normal Rolling Production.The detection error of kink position is directly affected set height and controls effect by it, thus affecting belt steel product quality.Current kink position detecting device is unreasonable because of its structure, in production, fault rate is higher, light then cause because the transmission of set amount causes that finished product volume slits the quality problems such as limit, interior pine, heavy then directly even break at the excessive stacking steel scrap of finishing stand inner sleeve amount or overtension drawing down.
Current head, drive form mainly has two kinds.One is to drive looper to swing with motor by power transmission shaft；One is to drive kink to swing with oil cylinder by toggle.And kink position detecting device has two kinds, one is angular encoder, calculates loop back roll position by the angle recorded in conjunction with kink swing arm physical quantity；One is that linear transducer passes through measuring and calculating linear course again through linkage physical quantity reckoning loop back roll position.Motor drives kink, and commonly used is angular encoder form at present；The kink of hydraulic oil cylinder driving is widely used at present is also angular encoder, also has part to adopt and follows driving oil cylinder, calculates the form of kink position by detecting oil cylinder stroke.
It is connected by shaft coupling between angular encoder with kink body.The accuracy of detection of encoder self is very high, but this type of attachment, encoder is required significantly high with the axiality of kink body rotating shaft, because fit clearance is only small between code-disc and its housing, the slightly different heart between kink rotating shaft and encoder, easilying lead to other strength between code-disc and housing, and encoder axle is very thin, the other strength between code-disc and housing easilys lead to encoder axle and breaks.But it is on-the-spot actual it is difficult to ensure that axiality between kink axle and encoder, because the distance between support and rotating shaft body is very short, during actual installation at the scene, detection code table does not have placement space to cannot be carried out the measurement adjustment of axiality at all, and rely only on fabrication and installation precision initial when making kink frame body, device or kink framework once alternate coding at the scene, axiality is just difficult to be guaranteed.Even if it is good for starting axiality, due in the operation of rolling, main transmission exists all the time dynamically stings steel prompt drop, various external disturbance it is constantly present again in the stable rolling stage, it is difficult to remain constant speeds match relation between each frame, in addition every block of steel certainly exists conforming to a conventional pattern and playing set after threading when throwing steel, so adjustment of loop is non-frequently, gap is easily ground between rotating shaft and axle sleeve, this causes that again the axiality between encoder and kink rotating shaft is deteriorated, strengthen the probability of damage of encoder, the detection error that additionally rotating shaft place gap causes is amplified to loop back roll place will cause very big detection error, and be that both maintenances axiality often changes large shaft sleeve and rotating shaft also leads to more maintenance time and more maintenance cost.Rear promising protection encoder axle will be connected with thin reed between encoder with encoder support, but thin reed also often ruptures.Also there is the mode flexibly connected taking to allow concentricity scarcely between kink rotating shaft and encoder, but this connection makes to be difficult to when kink frequently regulates between kink rotating shaft position and coder catcher follow in real time with accurate feedback kink position thus causing tower-loop control distortion because flexibility catcher exists easily deformable characteristic, although having the mode adopting fuzzy control later to make up the defect of this respect, but this being likely to and is filtered out by genuine position change signal and bring new control problem.
In recent years, begin with and take to follow driving oil cylinder and use the Linear displacement transducer method to detect kink position.This method, because of the nearly loop back roll body of oil cylinder pin joint, can relatively accurately reflect loop back roll physical location, thus the small-gap suture impact of kink framework roller pin can be ignored.But this method in use there is also defect.The method adopting Linear displacement transducer has two kinds of forms at present, and one is integrated in oil cylinder, and one is attempted by outside oil cylinder.Displacement transducer is arranged on the form in master cylinder, and more emat sensor is both needed to dismounting master cylinder oil pipe and end cap every time, adds kink place steam iron sheet many bolts easy-to-rust, and end cap is difficult to dismounting, and more emat sensor all can expend time a few hours every time；It is attempted by this external form of oil cylinder, one adopts coaxial pins with main oil cylinder piston pike pole head, one is attempted by oil cylinder body with anchor ear, two bolts of little axle and anchor ear only need to be dismantled during this mode replacing sensor, replacing speed is relatively fast, but sensor itself is required also significantly high with the depth of parallelism of master cylinder axis by this installation, otherwise frequently regulate tension sensor also can damage, additionally, because adding external sensor jacket bar and protection cylinder, need to ensure good lubrication between sheath rod valve piston and protection cylinder, the region of de-scaling water between bigger interstand cooling water or even high pressure frame is there is as hot fine rolling kink place, need often to carry out detecting device refueling to safeguard.And because loop back roll itself contacts with the strip, looper from strip steel apart from close, for preventing cylinder seal to be baked damage, also being installed in the lower section of looper for preventing detecting element to be baked damage, master cylinder and detecting device, this location device and medium pipeline are numerous and diverse, narrow space, greasy dirt and iron sheet are many, are difficult to Inspection and maintenance timely at ordinary times, still suffer from the fault that many loopers cause in production process.And both forms, it is intended to dismantle this sensor body and associated connections when changing oil cylinder every time, extends replacing construction, add sensor and pull the probability trampling damage.
It addition, the looper kink swing frame of at present design is articulated with kink bearing and is fixed on mill housing two kinds of forms.Kink bearing is fixed in the lifting beam of afer bay inlet guide, afer bay guide and guard height according to roll surface location-appropriate adjustment particularly for solve the problem guide and guard height adjustment amount such as skidding bigger time, kink bearing pursuit movement, kink position should have certain displacement mutually.Adopting the form of hydraulic oil cylinder driving, driving cylinder base is also articulated with memorial archway and two kinds of forms of kink bearing, and conventional linear transducer is attached to the stroke of oil cylinder detection oil cylinder.Kink drives the mode that oil cylinder and swing frame are articulated with on different fixing seat, there is gap at looper, afer bay guide and guard position adjustment is excessive and demarcates in inaccurate situation, it is easy to the relative position relation causing the pre-buried position of kink and afer bay guide and guard surface is incorrect thus causing that threading moment strip steel clashes into waft on afer bay guide and guard or strip steel and affecting afer bay and nip.
Through retrieval, prior art also has relevant introduction, specific as follows: Chinese patent CN203711484U discloses " finish rolling piston detector part coupling arrangement ", it alleviates the kink assembly impact to detecting device in production process by being evenly arranged nylon rod on the catcher dish that couples respectively in loop back roll rotating shaft and encoder axle, but this flexibly connecting the problem inherently having the detection delary distortion caused because of elastic deformation, simultaneously it can not solve kink rotating shaft place and impacts the gap the produced detection error problem to loop back roll physical location.
Chinese patent CN201744498U discloses " automatic loop detection device ", it by adopting insulating coupling between kink rotating shaft and encoder, and outside encoder, set up protective cover, in order to solve the peripheral interference such as electric looper electric current loop and insitu moisture, improve encoder accuracy of detection.But its on how to avoid kink assembly on encoder not coaxially impact and kink shaft position wearing clearance detection impact do not suggest that effective solution.
Chinese patent CN201048431 discloses " a kind of CCD loop scanner ", the reasonable combination in the loops such as its reasonable disposition passing through the first-class hardware of optical frames and signal pickup circuit, avoid radiation interference, what it adopted is a kind of optical principle detector, it not same category with this case, be not suitable for the environment that hot rolling mill loopers region steam is bigger yet.
Chinese patent CN201078369 discloses " position detection apparatus for external type hydraulic cylinder ", and it is by with driving oil cylinder the method connecing an external magnetic scale, and solution magnetic scale breaks down and need to change the technical problem of difficulty, reduces fault rate and replacing construction.But this mode of this method is because of its internal structure it cannot be guaranteed that lubrication, and magnetic scale draws bad fault rate higher in actual use.And because it needs to ensure lubrication, the dry and hard even roasting bad detecting element of lubricant medium can be caused because of high-temperature baking kink is installed above, so it can be only installed at below kink framework, and kink lower dielectric pipeline and other structural member are more, dismounting and change constructional difficulties, detecting device in this form inapplicable in kink region.And it is only limited to by the mode of hydraulic oil cylinder driving, for driving the form of kink with motor and inapplicable.Therefore, above-mentioned technical problem is solved in the urgent need to a kind of new technical scheme.
