Abstract
The present invention proposes a kind of milling train downstairs pad position device for fast detecting and method, the device includes scale bar and Duct fixing clamp, scale bar front end is connected with Duct fixing clamp configuration, uniform intervals are provided with several reading level portions on scale bar, the number in reading level portion is corresponding with the series of downstairs pad, and the number that level portion is read by observing determines the series of downstairs pad.Low manufacture cost of the present invention, live adverse circumstances are applicable, safeguard that method is easy to spread using simply.
Description
Technical field
The invention belongs to the technical field of the milling train downstairs pad of hot rolling mill, more particularly to a kind of milling train downstairs pad position
Device for fast detecting and method.
Background technology
The rolling premise of hot-strip seek to ensure each frame rolling horizontal line must in same level, but with
The use of roll (working roll and support roller) inevitably causes the loss and replacing of roll, and this is just needed by lower rank
The position adjustments of ladder pad compensate the difference in height of roll line to ensure that rolling horizontal line is constant.
Existing milling train downstairs pad determines that location method is the position sensing that telescopic oil cylinder is padded by being built in downstairs
What device value of feedback calculated.Once the position sensor of downstairs pad breaks down, the physical location that can not feed back step pad is come really
Determine height of rolling line, then finishing mill does not possess steel rolling condition.But changing position sensor but needs longer time, due to life
210bar high pressure liquid force feed is filled between term in the oil cylinder, thus in the replacement operation for carrying out downstairs pad position sensor
Before, it is necessary to interrupt and produce and close valve pressure release to ensure the person and equipment safety, while the whole process of more emat sensor is at least
45min is needed to complete.This will inevitably cause the disconnected of front-end-of-line conticaster to be poured, the production disruption of roll line.
The content of the invention
The technical problems to be solved by the invention are to be directed to above-mentioned problem, there is provided a kind of milling train downstairs pad position
Device for fast detecting and method are put, realization manually adjusts downstairs pad position, avoids production disruption, improves operating rate of rolling mill.
Technical scheme is used by the present invention solves above-mentioned technical problem：A kind of milling train downstairs pad position quick detection
Device, it is characterised in that including scale bar and Duct fixing clamp, the scale bar front end is connected with Duct fixing clamp configuration, marks
Uniform intervals are provided with several reading level portions in foot bar, and the number in the reading level portion is corresponding with the series of downstairs pad.
By such scheme, the reading level portion is projection or groove or vertical element.
By such scheme, the number for reading level portion is 13, and adjacent two spacing read between level portion are
150mm。
By such scheme, the scale bar is cylindrical bar, and the Duct fixing clamp is all provided with including two pieces of symmetrically arranged centers
It is made up of the rectangular block of semi-circular recesses, the both sides of two pieces of rectangular blocks are connected by bolt, and the diameter of the semi-circular recesses omits
Less than the diameter of scale bar.
A kind of milling train downstairs pad position quick determination method, it is characterised in that comprise the following steps:
A) location and installation, first, the harmonic series side of the Duct fixing clamp and milling train downstairs pad is weldingly connected, then
By the rear end of the scale bar through the through hole on downstairs pad support, scale bar is set to be located at same level with cylinder putter
On, then downstairs pad is moved to the first level position, adjusting the position of scale bar makes first of outermost end to read level portion and oil cylinder
Mounting flange be located in same horizontal line, finally tighten Duct fixing clamp bolt clamp scale bar front end；
B) series detects, when step pad is subjected to displacement instantly, by observing the reading level portion corresponding with cylinder flange come really
The corresponding series of ladder is fixed, level portion can also be read as desired by observation downstairs pad is adjusted to corresponding series.
The beneficial effects of the invention are as follows：The 1st, a kind of milling train downstairs pad position device for fast detecting and method are provided, can be with
Significantly shorten the processing time of downstairs pad position sensor fault, resume production rapidly, avoid production disruption, improve milling train and make
Industry rate；2nd, low manufacture cost, live adverse circumstances are applicable, safeguard and use simply, in the case where manually adjusting downstairs pad position pattern
Even can the position of substitution sensor completely.
Brief description of the drawings
Fig. 1 is the structural representation of one embodiment of the invention.
Fig. 2 is the scheme of installation of one embodiment of the invention.
Wherein：1. scale bar, 2. Duct fixing clamps, 3. reading level portions, 4. downstairs pads, 5. through holes, 6. oil cylinders, 7. oil cylinders push away
Bar, 8. mounting flanges, 9. position sensors.
Embodiment
To more fully understand the present invention, the invention will be further described with reference to the accompanying drawings and examples.
As shown in Figure 1-2, a kind of milling train downstairs pad position device for fast detecting, including scale bar 1 and Duct fixing clamp 2,
Scale bar front end is connected with Duct fixing clamp configuration, and uniform intervals are provided with several reading level portions 3, its number and downstairs pad on scale bar
4 series is identical.
It can be projection or groove or vertical element etc. to read level portion, and the number for reading level portion is 13, the series with downstairs pad
Corresponding, two adjacent spacing read between level portion are 150mm.
Scale bar is cylindrical bar, and Duct fixing clamp includes the rectangular block that two pieces of symmetrically arranged centers are equipped with semi-circular recesses
Composition, the both sides of two pieces of rectangular blocks are connected by bolt, and the diameter of semi-circular recesses is slightly less than the diameter of scale bar.
When the position sensor 9 set on oil cylinder 6 breaks down, the downstairs pad position device for fast detecting can be thrown
Enter to use, its detection method comprises the following steps:
A) location and installation, first, the harmonic series side of Duct fixing clamp and milling train downstairs pad is weldingly connected, then will mark
The rear end of foot bar passes through the through hole 5 on downstairs pad support, scale bar is located at cylinder putter 7 in same level, then will
Downstairs pad is moved to the first level position, and adjusting the position of scale bar makes first fixation for reading level portion and oil cylinder of outermost end
For orchid 8 in same horizontal line, the bolt for finally tightening Duct fixing clamp clamps the front end of scale bar；
B) series detects, when step pad is subjected to displacement instantly, by observing the reading level portion corresponding with cylinder flange come really
The corresponding series of ladder is fixed, level portion can also be read as desired by observation downstairs pad is adjusted to corresponding series.
