Abstract
The utility model relates to a R2 guiding position protection device, which belongs to the technical field of steel rolling. The device comprises a fixed solid (2), a proximity switch (3), a separation blade (4) and an open pore (6). The fixed solid (2) is fixed on a hydraulic cylinder (1). An iron sheet is arranged on the hydraulic cylinder (1). The iron sheet is provided with the open pore (6) for installing the proximity switch (3). The separation blade (4) is arranged on a R2 guiding position and is in hard link with the R2 guiding position. The R2 guiding position protection device is suitable for a rough rolling R2 guiding position device, has the advantages of detecting the position of the R2 guiding position in advance, avoiding the R2 guiding position being hit, guaranteeing the successful production of the rolling line and also having high cost-performance ratio and simple manufacturing.
Description
Technical field
The utility model belongs to technical field of steel rolling, particularly provides a kind of R2 to lead a protective device, is applicable to that technical field of steel rolling guarantees that rolling line trouble-free operation, Reasonable Protection roughing R2 lead the position.
Background technology
Moved hot rolling subsidiary factory of steel company since going into operation the end of the year in 2006, equipment is relatively stable, but repeatedly takes place to cause steel scrap because the R2 inlet is led the position, even the accident of being forced to stop production, and has caused very big passivity for the production of hot rolling subsidiary factory and company.
At first, lead the position and do not rise, cause being with the steel can't be rolling by R2 smoothly, cause steel scrap, suppose our rolling ordinary steel with roll gap, 1000 yuan of ton steel profits, 30 tons of monovolume weight, so one of steel scrap we will lose 30,000 yuan.
Secondly, lead the position and do not rise with roll gap, cause being with steel that R2 is led a collision deformation or damage, produce steel scrap so certainly, we must stop production to overhaul simultaneously, our production certainly will be upset like this; Iff being to lead the position slight distortion arranged, will online reparation or off-line reparation, to spend the time of a few hours so certainly; If R2 leads the position by collision deformation and can't use on the machine, perhaps use on the machine and may also can cause a hidden trouble, we must pull down again so, the R2 that more renews leads the position, except rehabilitation expense, may also have other expense, if these are added up, certainly will result in greater loss.
Summary of the invention
The purpose of this utility model is to provide a kind of R2 to lead a protective device, has solved in the daily rolling process us and can't know that R2 leads the particular location of position, can't judge that R2 leads an actual position, causes hitting the problem of leading the position with the steel mistake.
The utility model comprise this device comprise fixing solid, near switch, catch, open pore; An iron plate is installed in the hydraulic cylinder top in the fixing hydraulic cylinder top that is fixed on admittedly, has an open pore to install near switch in the iron plate top, and catch is installed in R2 and leads a top, and leading the position with R2 is hard link, moves up and down along with leading the position.
Described in the utility model fixing uses steel to manufacture admittedly; Fixing is active open admittedly, can freely adjust its position on hydraulic cylinder; On fixing admittedly open pore is set, open pore is 50 * 30mm, can adjust near the position of the switch arbitrarily.
Protective device of the present utility model is all installed and welding with speciality.
The R2 guide device is connected together with the backing roll balancing chain by hydraulic cylinder, and in Steel Rolling Control, the relative position of leading position and balance hydraulic cylinder is constant; It mainly is to monitor the action of leading the position and monitor its position indirectly by pressure that R2 leads the position, owing to be pressure control, so have the position of leading that mechanical jam or otherwise reason cause not have regular event leading the position, just may cause being with steel to hit and lead the position, with device damage.Therefore we have had preliminary idea, lead the relative position of position by monitor hydraulic cylinder and R2 near switch, in case deviation appears in relative position, will lose near switching signal so, provide warning on picture, judge that according to reporting to the police R2 leads the physical location of position.After this monitoring arrangement has been installed, the band steel never took place hit the incident that R2 leads the position.
Advantage of the present utility model is, can detect in advance and lead bit position, avoids leading the position by the generation of the situation of hitting, and guarantees the smooth production of rolling line.Possess the cost performance height simultaneously, make simple and easy.
Description of drawings
Fig. 1, for leading the structural representation of a monitoring and protection devices type.Wherein, hydraulic cylinder 1, fixing solid 2, lead position 5 near switch 3, catch 4, R2.
Fig. 2 is fixing, and solid top is welded with the iron plate of installation near switch.Wherein, open pore 6.
The specific embodiment
Fig. 1 is a kind of specific embodiment of the present utility model.As shown in the figure, comprise fixing solid 2, near switch 3, catch 4, open pore 6; Fixing solid 2 are fixed on the hydraulic cylinder top, and an iron plate is installed in hydraulic cylinder 1 top, have an open pore 6 to be used for installing near switch 3 in the iron plate top; Being designed to open pore is for when the R2 roller directly changes, can lead elongated iron bar baffle plate of top welding at R2 according to the position of actual conditions easy on and off adjustment near switch, is used for the inductive proximity switch signal.
Claims (3)
1. a R2 leads a protective device, it is characterized in that, this device comprises fixing solid (2), near switch (3), catch (4), open pore (6); Fixing solid (2) are fixed on hydraulic cylinder (1) top, and an iron plate is installed in hydraulic cylinder (1) top, have an open pore (6) to install near switch (3) in the iron plate top, and catch (4) is installed in R2 and leads (5) top, position.
2. device according to claim 1 is characterized in that, described fixing solid (2) use steel to manufacture.
3. device according to claim 1 is characterized in that, on fixing solid (2) open pore is set, and open pore is 50 * 30mm.
