Abstract
The utility model relates to an automatic loop detection device in the hot rolling strip steel field and is characterized in that: one end of a loop device is connected with an absolute value encoder through an insulating coupling and a flange; a mechanical traveling mechanism is disposed outside the loop device; and a protective casing is disposed outside the encoder. The advantages are as follows: the automatic loop detection device can detect real-time data during the lifting and dropping processes of loops directly and has excellent following performance and strong anti-interference performance.
Description
Technical field
The utility model relates to the kink automatic detection device in the hot-strip field.
Background technology
The Comprehensive Control of tandem hot strip mill mm finishing mill unit kink is the key that can band aluminium milling train group run well, and also is simultaneously the prerequisite that guarantees that can belt steel thickness and width quality control stable.Through sufficient market survey, in the hot-strip field, the electric looper systems that adopt more, it is the angle of coming the indirect calculation kink to play cover and conform to a conventional pattern by electric current loop, the precision of measuring is not high, can not satisfy requirement, thereby can't realize efficient rolling and high-quality rolling kink high-acruracy survey and control.Therefore, improve the precision that kink detects, help improving the overall precision of China's kink servo-control system.
Summary of the invention
The purpose of this utility model provides and a kind ofly can detect directly that kink hoists and the kink automatic detection device of the real time data of the process of landing, and followability is good, strong interference immunity.
For achieving the above object, the utility model is achieved through the following technical solutions:
The kink automatic detection device is connected with encoder at an end of looper by insulating coupling and flange.
Described encoder is an absolute value encoder; Outside at looper is provided with mechanical running mechanism; Described encoder outside is provided with guard shield.
Compared with prior art, the beneficial effects of the utility model are:
1, can realize direct measurement, quick and precisely;
2, signal accuracy height, anti-interference strong, transfer rate is fast;
3, programming mode is flexible, and is workable;
4, degree of protection reaches IP 68, but long-term work is at extremely abominable site environment;
5, followability is good, resisting strong impact and vibration.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1-insulating coupling 2-looper 3-mechanical running mechanism 4-flange 5-base 6-encoder 7-guard shield 8-loop back roll
The specific embodiment
See Fig. 1, the kink automatic detection device, mechanical running mechanism 3, flange 4, base 5, encoder 6, insulating coupling 1, guard shield 7 are connected with absolute value encoder 6 at an end of looper 2 by insulating coupling 1 and flange 4.Be provided with mechanical running mechanism 3 in the outside of looper 2; Absolute value encoder 6 outsides are provided with guard shield 7.
The kink automatic detection device is directly installed on the milling train looper 2, can directly measures fast and accurately, and transmit measurement data, solve the band steel second flow amount that various interference causes and the disturbance of tension force; In view of on-the-spot water under high pressure spray, the most evil bad environment of many corrosive liquids has designed guard shield, can reach the IP68 high-protection level, and device still can normally be worked under rugged environment for a long time accurately.
Utilize mechanical running mechanism and encoder directly detect kink play cover and conform to a conventional pattern and running in real-time angle value, thereby can better detect and control the position of kink.Adopt absolute value encoder directly to measure the angle of loop back roll 8 in real time.
