Abstract
The utility model relates to a hot galvanizing unit passivation system on-line roll change device, the technical solution is that the hot galvanizing unit passivation system on-line roll change device comprises a guiding rail (6) and a roll change trolley (5), wherein the roll change trolley is arranged on the guiding rail, and can move on the guiding rail, and the guiding rail is provided with a plurality of pulleys (10). When exchanging a drying roll, a lower drying roll firstly fall on the roll change trolley, then a unlocking device and a sliding plate are opened, the roll change trolley is pulled outside a memorial archway, thereby being capable of pulling the drying roll out and swinging away. The hot galvanizing unit passivation system on-line roll change device has the beneficial effects that the hot galvanizing unit passivation system on-line roll change device can conveniently and rapidly on-line exchange of the lower drying roll through the roll change trolley, has the characteristics of simple, convenient, flexible, safe and reliable structure, reduces the labor strength of workers, and increases the production efficiency.
Description
Affiliated technical field:
The utility model relates to the roll changing rig formerly of a kind of online roll changing rig, particularly pot galvanize unit passivation system.
Background technology:
After passivation system is positioned at pot galvanize unit outlet section straightening machine.During the hot-dip galvanizing sheet steel passivation; chromic acid passivation solution through the squirt pump pressurization is ejected into the upper and lower surface of band steel; the band steel that has passivating solution is squeezed by squeezing roller the time removes unnecessary passivating solution; make and form the very thin passivation protection film of one deck on the zinc coating of belt steel surface, to improve the Corrosion Protection of galvanized sheet.If extract inhomogeneous, then unnecessary passivating solution through behind the drying unit, form the uneven passive film of color and luster (passivation spot) on its surface, have a strong impact on the visual appearance of galvanized sheet.Thereby be difficult to satisfy the requirement of user to quality product.Because galvanizing line passivation squeezing roller does not generally speaking have transmission system, only to rotate by the frictional force between squeezing roller and the band steel up and down, its wearing and tearing are very fast, change comparatively frequent.Must shut down and cut off steel band during squeezing roller under changing, by crane and artificial the cooperation carrying out roll change, each roll changing time needs 5-6 hour approximately, and labor strength is big, and roll changing time is long, is unfavorable for the quick replacing of production line spare part, influences production efficiency.The roll-changing method that also has is that following squeezing roller cylinder stroke is become big, realizes online roll change by crane and counterweight roll change instrument with artificial cooperation, and this kind operation is comparatively loaded down with trivial details and safety coefficient is lower.
The utility model content:
The utility model purpose provides the online roll changing rig of a kind of pot galvanize unit passivation system, utilizes roll change buggy just can easily realize down quickly the online replacing of squeezing roller, solves the problems referred to above that exist in the background technology.
The technical solution of the utility model is: the online roll changing rig of pot galvanize unit passivation system comprises guide rail and roll change buggy, and roll change buggy is installed on the guide rail, and can move on guide rail.
Guide rail is provided with several pulleys, and evenly arranges.
Each pulley uses two covers side by side, totally 5 ~ 10 cover pulleys, and even the layout.
When changing squeezing roller, at first will descend squeezing roller to fall on the roll change buggy, and open locking latches and slide plate then, the pulling roll change buggy moves to outside the memorial archway, just can walk descending squeezing roller to pull out also handling.During the dress roller, new following squeezing roller is put into roll change buggy, will descend squeezing roller and roll change buggy to push together in the frame, locked locking latches is installed slide plate, and works better just can come into operation.
The beneficial effects of the utility model are: original equipment integral body is not changed, utilize roll change buggy just can easily realize down quickly the online replacing of squeezing roller, have simple in structure, convenient, flexible, safe, reliable characteristics have reduced labor strength, have improved production efficiency.
Description of drawings:
Fig. 1 is the utility model example structure synoptic diagram;
Fig. 2 is the utility model embodiment side-view;
Fig. 3 is the utility model embodiment part sectioned view;
Among the figure: 1. handwheel, 2. go up squeezing roller, 3. descend squeezing roller, 4. locking latches, 5. roll change buggy, 6. guide rail, 7. cylinder, 8. memorial archway, 9. slide plate, 10. pulley, 11..
Embodiment:
Below in conjunction with accompanying drawing, the utility model is described in further detail by embodiment.
With reference to accompanying drawing 1,2,3, the online roll changing rig of pot galvanize unit passivation system comprises guide rail 6 and roll change buggy 5, roll change buggy is installed on the guide rail, and can move on guide rail, and guide rail is in the square Hollow Steel, pulley 10 is installed in per 400 ~ 500 millimeters spacing perforates, be provided with axle 11 in the pulley, its pulley can replace with 6203 bearings, and each pulley uses two covers side by side, totally 5 cover pulleys, and even the layout.Roll change buggy is that angle steel is welded into framework, and spacing buting iron is welded in the bearing support position.When changing under the passivation roller squeezing roller 3, at first cylinder 7 is fallen extreme lower position.The cylinder effective stroke is 50 ~ 100mm, and its air pressure can be regulated by the relief valve in the gas circuit, and regulation range is 0.03～0.7 MPa.When cylinder dropped to extreme lower position, following squeezing roller also can drop to extreme lower position, this at present squeezing roller fall on the roll change buggy, dismantle this moment behind locking latches 4 and the slide plate 9 roll change buggy outside changing side is pushed out to memorial archway 8, hang by crane and get final product.As long as by pulling down handwheel 1, just can directly change easily when replacing with on the squeezing roller squeezing roller 2.When adorning new roller, following squeezing roller is hung by crane and puts into roll change buggy, and hand push is gone in the memorial archway frame, and locked locking latches is installed slide plate and can be finished.Have characteristics simple in structure, convenient, flexible, safe, reliable, reduced labor strength, improved production efficiency.
Claims (3)
1. the online roll changing rig of pot galvanize unit passivation system is characterized in that comprising guide rail (6) and roll change buggy (5), and roll change buggy is installed on the guide rail, and can move on guide rail.
