Abstract
The utility model relates to a rotatory detection device of hot rolling sheet rolling mill lopper roll belongs to metallurgical industry hot rolling sheet equipment technical field. Technical scheme is: contain proximity switch (1), baffle (2), loop roll chock (3), lopper roll (4) and proximity switch fixed bolster (5), proximity switch fixed bolster (5) are fixed on loop roll chock (3), establish on proximity switch fixed bolster (5) proximity switch (1), proximity switch (1) is connected with rolling mill control system, be close to on lopper roll (4) edge of loop roll chock (3) one end, along circumferencial direction four evenly fixed baffle (2), be equipped with the clearance between baffle (2) and proximity switch (1). The beneficial effects of the utility model are that: a roll board galled spots as the timely feedback signal of lopper roll irrotational, is avoided to the lopper roll condition of rotating in can real -time detection the rolling process, reduces the quality accident.
Description
Technical field
The utility model relates to a kind of hot-rolled coil milling train loop back roll rotation detection device, belongs to metallurgy industry hot-rolled coil equipment technical field.
Background technology
At present, the surface quality requirements of market to hot-rolled coil is more and more higher, and this just requires that equipment will have higher stability, relies on kink to support roll bending, ensure micro tension milling between frame between mm finishing mill unit.The loop back roll that milling train kink contacts with roll bending belongs to idler roller, rotates under the drive of roll bending, if loop back roll bearing damage, loop back roll just can not rotate, and roll bending and loop back roll friction, cause roll bending galled spots, forms roll bending surface quality accident, affects product quality.
Utility model content
The utility model object is to provide a kind of hot-rolled coil milling train loop back roll rotation detection device; loop back roll rotation situation in the detection operation of rolling that can be real-time; when loop back roll does not turn; proximity switch just can not detect signal; the shutdown thus Triggering Control System is reported to the police, solves Problems existing in background technology.
The technical solution of the utility model is:
A kind of hot-rolled coil milling train loop back roll rotation detection device, comprise proximity switch, baffle plate, loop back roll bearing block, loop back roll and proximity switch fixed support, proximity switch fixed support is fixed on loop back roll bearing block, proximity switch is located on proximity switch fixed support, proximity switch is connected with mill control system, on the loop back roll edge of loop back roll bearing block one end, along the circumferential direction evenly fix four baffle plates, between baffle plate and proximity switch, be provided with gap.
Adopt the utility model; in the operation of rolling; when loop back roll rotates, baffle plate together rotates with loop back roll; proximity switch sends pulse signal and delivers to control system; when pulse-free signal, timely trigger alarm is shut down; avoid roll bending surperficial because loop back roll can not rotate scratch, thus avoid roll bending surface quality accident.
The beneficial effects of the utility model are: can detect loop back roll rotation situation in the operation of rolling in real time, when the timely feedback signal of loop back roll non rotating, avoid roll bending galled spots, reduce quality accident.
Accompanying drawing explanation
Fig. 1 is the utility model top view;
Fig. 2 is the utility model front view;
In figure: proximity switch 1, baffle plate 2, loop back roll bearing block 3, loop back roll 4, proximity switch fixed support 5.
Detailed description of the invention
Below in conjunction with accompanying drawing, by example, the utility model is described in further detail.
With reference to accompanying drawing 1,2, a kind of hot-rolled coil milling train loop back roll rotation detection device, comprise proximity switch 1, baffle plate 2, loop back roll bearing block 3, loop back roll 4 and proximity switch fixed support 5, proximity switch fixed support 5 is fixed on loop back roll bearing block 3, proximity switch 1 is located on proximity switch fixed support 5, proximity switch 1 is connected with mill control system, on loop back roll 4 edge of loop back roll bearing block 3 one end, along the circumferential direction evenly fix four baffle plates 2, between baffle plate 2 and proximity switch 1, be provided with gap.
In the present embodiment, proximity switch fixed support 5 is welded on loop back roll bearing block 3, proximity switch 1 can move left and right on proximity switch fixed support 5, to adjust the distance between proximity switch 1 and baffle plate 2, baffle plate 2 specification is 35mm*35mm, totally four, be welded on uniformly on the edge of loop back roll 4.
In the hot-rolled coil operation of rolling, rotate under the drive of roll bending, loop back roll 4 rotates, and baffle plate 2 also together rotates with loop back roll 4, and proximity switch 1 sends pulse signal and delivers to mill control system.If loop back roll bearing damage; or other reason causes loop back roll 4 not rotate, proximity switch 1 just can not detect signal, thus triggers mill control system warning shutdown; avoid roll bending surperficial because loop back roll can not rotate scratch, thus avoid roll bending surface quality accident.
Claims (1)
1. a hot-rolled coil milling train loop back roll rotation detection device, it is characterized in that comprising proximity switch (1), baffle plate (2), loop back roll bearing block (3), loop back roll (4) and proximity switch fixed support (5), proximity switch fixed support (5) is fixed on loop back roll bearing block (3), proximity switch (1) is located on proximity switch fixed support (5), proximity switch (1) is connected with mill control system, on loop back roll (4) edge of loop back roll bearing block (3) one end, along the circumferential direction evenly fix four baffle plates (2), gap is provided with between baffle plate (2) and proximity switch (1).
