Description

Mill anvil roll suspender

Technical field

The utility model relates to thick (essence) mill apparatus for examination and repair of a kind of metallurgy industry, is specially a kind of mill anvil roll suspender.

Background technology

At present in the maintenance process of metallurgy industry mill, use finish the work roller, anvil roll of instruments such as horizontal hanging beam, suspender belt, rigging to change the outfit usually; Perhaps adopt armful nip rolls or anvil roll driving surface clamp to change the outfit.When adopting crossbeam, rigging lifting, need manual operation, exist that lifting is loaded down with trivial details, the replacing time is long, many shortcomings such as poor stability.In addition in the roll nip clamp uses, the detent mechanism of clamp and clamping structure be because structural limitations, the cantilever deviations takes place often and lost efficacy, and clamp is embraced situations such as folder driving surface wear liner, bolt looseness and hurt roll surface.

Summary of the invention

The utility model for solve the suspender that exists in the prior art use inconvenient, complex operation, problem such as poor stability and a kind of mill anvil roll suspender is provided.

The utility model is realized by following technical scheme, a kind of mill anvil roll suspender, comprise and have the clamping device that hook connects device, be provided with the gravity type boat davit closing device between the entablatrance of clamp structure and the central sill, the gravity type boat davit closing device comprises and entablatrance bonded assembly guidepost, with entablatrance pivotally attached gravity hook, with central sill bonded assembly orienting sleeve, orienting sleeve and guidepost socket, orienting sleeve are provided with inclined-plane pedestal hook, are hinged with hush panel under the inclined-plane pedestal hook.

Wherein the gravity type boat davit closing device is crucial core apparatus, the gravity hook since its hinge-point and center of gravity do not overlap, so the bill of gravity hook bottom is all the time near orienting sleeve, position when entablatrance and central sill are in compressive state (this moment, clamping device was to be in folding condition), entablatrance is pressed down, entablatrance is being with the gravity hook to move downward under the effect of orienting sleeve and guidepost, slip over hush panel under the gravity hook, after upward movement again, the bill of gravity hook is stirred hush panel at once and is upwards rotated, hush panel has been filled up the groove that colludes under the inclined-plane pedestal hook, this moment, inclined-plane pedestal hook just can not tangle the gravity hook again, gravity hook and entablatrance just continue upward movement, and distance increases between entablatrance and the central sill, are in folding condition (this moment, clamping device was in closure state).The advantage of this device is that the mutual action by gravity hook and inclined-plane pedestal hook and hush panel can be finished clamping device to open or closed action reliably, and clamping device just can pick up the anvil roll of mill lifting maintenance or replacing.

The both sides of the entablatrance of clamp structure are connected with pull bar, are hinged with hinge arm plate on the pull bar, and the both sides of the central sill of clamp structure are hinged with jig arm, and hinge arm plate and jig arm are hinged.Utilize caliper gravity, the lifting by entablatrance is that the hinge arm plate of two groups of pull bars and intersection produces motion, makes jig arm finish holding action in the lifting.

The structure that hook connects device comprises two hangers that are hinged on the entablatrance, and the lower end of two hangers is connected with gangbar, and the hanger inboard is fixed with collision block.

Be fixed with two worker's registration devices at the two ends of central sill, two worker's registration device results comprise that the bottom has the box body of first locating surface, are connected with the swivel that has second locating surface by rotating shaft in the box body, and swivel and box body are fixed by the locating dowel pin cross-under.

Advantages such as it is convenient, rapid, reliable to the utlity model has replacing mill anvil roll, and it is directly perceived that suspender opens and closes mode of operation, accurate, and other suspender long service life is easy to operate, safe and reliable relatively, and range of use is wide.
