Description
Technical field
The utility model relates to chilling roller waterproofing devices in a kind of hot-rolling strip steel conveying roll table, belong to metallurgy industry hot-strip
Rollgang equipment technical field.
Background technique
Hot-rolled strip production line runout table is located at strip cooling zone after mm finishing mill unit, and the strip after rolling is transported to
Downcoiler.Runout table is about 105340mm, amounts to 352, runout table is divided into outer chilling roller and two kinds of interior chilling roller.Conveying
Chilling roller is located at finishing mill outlet and starts below first 36 and Surface testing instrument roller 24 in roller-way, amounts to 60.The interior chilling roller
Road driven separately is hollow roller-way, body surface spraying abrasion-proof layer, roller diameter 260mm, barrel length 1580mm.It is interior
For chilling roller by being connected on the pipe on the outside of bearing block with flange, water inlet pipe passes through the roller of pipe and interior chilling roller on the outside of bearing block
Neck is connected to intake antrum, and backwater cavity is formed between the pipe on the outside of water inlet pipe and bearing block, and return pipe is connected to backwater cavity.
When interior chilling roller works, interior chilling roller cooling water passes through in water inlet pipe to the hollow intake antrum of interior chilling roller, then via roll neck
On hole and cooling pipe between gap flow back to backwater cavity, finally by return pipe to collecting box.In interior chilling roller operation process
In, the sealing between interior chilling roller and bearing is easily worn, and cooling water generates buffer brake to sealing in backwater cavity, and cooling water is just
It can be penetrated into bearing from gap, cause bearing lubrication bad, roller-way is caused to damage.
Utility model content
The utility model aim is to provide chilling roller waterproofing device in a kind of hot-rolling strip steel conveying roll table, can be avoided cooling water
It is penetrated into bearing from backwater cavity, causes bearing lubrication bad, solve the problems, such as background technique.
The technical solution of the utility model is:
Chilling roller waterproofing device in a kind of hot-rolling strip steel conveying roll table, comprising water inlet pipe, return pipe, interior chilling roller, backwater cavity and
Intake antrum, interior chilling roller are hollow roller, are intake antrum inside interior chilling roller, interior chilling roller is connected by the pipe on the outside of flange and bearing block
It connects, the roll neck that water inlet pipe passes through pipe and interior chilling roller on the outside of bearing block is connected to intake antrum, on the outside of water inlet pipe and bearing block
Backwater cavity is formed between pipe, return pipe is connected to backwater cavity, the pipe that blocks water is equipped on the roll neck of interior chilling roller, block water tube outer surface
Circumferencial direction be equipped with multiple tracks sink.
The sink to block water on tube outer surface circumferencial direction is U-type groove.
The sink to block water on tube outer surface circumferencial direction is twice.
Using the utility model, in the operating of interior chilling roller, the pipe that blocks water also is rotated together with the roll neck of interior chilling roller, and the pipe that blocks water exists
In rotary course, by blocking water, the multiple tracks sink on pipe circumferencial direction forms multiple tracks water curtain, by the return water in backwater cavity in water curtain
Place blocks, and is effectively prevented and penetrates into bearing since cooling water occurs after abrasion in backwater cavity in sealing from gap, causes axis
Hold insufficient lubrication.
It is penetrated into bearing the beneficial effects of the utility model are: can be avoided cooling water from backwater cavity, leads to bearing lubrication
It is bad, it is ensured that the normal operation of interior chilling roller.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is that the utility model blocks water pipe structural schematic diagram；
In figure: water inlet pipe 1, return pipe 2, interior chilling roller 3, backwater cavity 4, intake antrum 5, sealing 6, the pipe 7 that blocks water, water curtain 1, water
Curtain 29, sink 10.
Specific embodiment
Below in conjunction with attached drawing, by example, the utility model is described in further detail.
Referring to attached drawing 1,2, chilling roller waterproofing device in a kind of hot-rolling strip steel conveying roll table, comprising water inlet pipe 1, return pipe 2, interior
Chilling roller 3, backwater cavity 4 and intake antrum 5, interior chilling roller 3 are hollow roller, are intake antrum 5 inside interior chilling roller 3, interior chilling roller 3 by flange with
Pipe connection on the outside of bearing block, the roll neck that water inlet pipe 1 passes through pipe and interior chilling roller 3 on the outside of bearing block are connected to intake antrum 5,
Backwater cavity 4 is formed between pipe on the outside of water inlet pipe 1 and bearing block, return pipe 2 is connected to backwater cavity 4, in the roll neck of interior chilling roller 3
It is equipped with the pipe 7 that blocks water, the circumferencial direction for 7 outer surface of pipe that blocks water is equipped with multiple tracks sink 10.
In the present embodiment, it blocks water and is provided with the U-shaped sink 10 of twice on 7 outer surface circumferencial direction of pipe, in the pipe 7 that blocks water is mounted on
On the roll neck of chilling roller 3.
Referring to attached drawing 1, arrow is the flow direction of cooling water, blocks water pipe 7 in rotary course, the twice to block water on pipe 7
Sink 10 drive backwater cavity in water formed twice water curtain, water curtain by backwater cavity return water block, effectively avoid due to
Cooling water penetrates into bearing from gap in backwater cavity after sealing appearance abrasion.
