The technical solution of the utility model is as follows:
The adjustable roll collar of rolling mill cooling device of a kind of combination comprises the frame cooling water pipe, the frame cooling water pipe is provided with nozzle, the lateral outer side water pipe of frame cooling water pipe links to each other with water pipe, it is characterized in that, be respectively arranged with two swivel joints on vertical outside water pipe of described frame cooling water pipe, be provided with swivelling pipe between described two swivel joints, the two ends of swivelling pipe link to each other with swivel joint by flange respectively, and swivelling pipe is provided with nozzle.
Described swivel joint is fixedlyed connected with vertical outside water pipe of frame cooling water pipe by flange.
The interspersed inside that is arranged on swivel joint of described vertical outside water pipe, swivel joint realizes that by rolling bearing movable sealing is connected with vertical outside water pipe; Water pipe and swivel joint are provided with alignment pin outside vertically.Realize relative motion by rolling bearing between inner core pipe and the overcoat, guarantee that by dedicated sealing member medium does not have leakage.Rotate swivelling pipe, the driven rotary joint rotates, adjust the spray angle of nozzle after, can by swivel joint with vertically outside the fixing swivelling pipe of alignment pin between the water pipe, prevent rotation.
The vertical perforation is provided with many vertical water pipes between the lateral outer side water pipe of described frame cooling water pipe.
Be respectively arranged with two swivel joints on described vertical water pipe, be provided with swivelling pipe between described two swivel joints, the two ends of swivelling pipe link to each other with swivel joint by flange respectively, and swivelling pipe is provided with nozzle.
The interspersed inside that is arranged on swivel joint of described vertical water pipe, swivel joint realizes that by rolling bearing movable sealing is connected with vertical water pipe; Be provided with alignment pin at vertical water pipe and swivel joint.
Advantage of the present utility model is:
The utility model adopts the frame cooling water pipe of band swivel joint, can by adjusting the spray angle that swivelling pipe changes cooling water, different collars effectively be cooled off according to mill milling pass size, is not subjected to the space constraints of other equipment such as frame.The utility model can be realized the rapid adjustment of cooling water spray angle, has both guaranteed the effective cooling to collars, has overcome the restriction of the device space, significantly improved the roll collars service life, reduced the steel rolling cost.The utility model is reasonable in design, and is safe and convenient to use.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is described further, but is not limited thereto.
Embodiment 1,
Shown in Fig. 1-2, the adjustable roll collar of rolling mill cooling device of a kind of combination comprises the frame cooling water pipe, the frame cooling water pipe is provided with nozzle 3, the lateral outer side water pipe 6 of frame cooling water pipe links to each other with water pipe 9, it is characterized in that, be respectively arranged with two swivel joints 1 on vertical outside water pipe 7 of described frame cooling water pipe, be provided with swivelling pipe 2 between described two swivel joints 1, the two ends of swivelling pipe 2 link to each other with swivel joint 1 by flange respectively, and swivelling pipe 2 is provided with nozzle 3.
Described swivel joint 1 is fixedlyed connected with vertical outside water pipe 7 of frame cooling water pipe by flange.
The vertical perforation is provided with many vertical water pipes 8 between the lateral outer side water pipe 6 of described frame cooling water pipe.
The course of work:
According to the structure of rolling-mill housing, the utility model is tilted to place.
According to the anglec of rotation that the size and the position of collars is provided with the utility model swivelling pipe 2 in advance, make its nozzle 3 and collars 4 need the position of cooling corresponding, be sprayed onto cool position with the cooling water of nozzle 3 ejections and be as the criterion.
