Background technology
The roll collar of rolling mill cooling device is one of important composition of hot-rolled steel equipment; Be mostly closed-in construction, its effect is that roll collar of rolling mill is cooled off, and is positioned at the collars top; Reduce the temperature of collars, the service life of raising collars through the normal temperature clean circulating water that sprays certain pressure and flow.Along with the raising of hot-rolled steel technology level, rolling mill structure is towards high rigidity, compact development, and rolling mill structure is compact day by day, and the space of therefore reserving to milling train annexes such as collars cooling devices diminishes; Even enough spaces are arranged so that bigger cooling water pipe to be installed; But must face the increase of rolling groove and the problems such as increase of collars size in the production later stage; If still adopt original cooling water pipe cooling collars, effect is bad, has a strong impact on the service life of collars; If simple dependence changed the collars cooling device, can increase production cost again.
Summary of the invention
For overcoming the deficiency of prior art, it is a kind of simple in structure that the present invention provides, the adjustable roll collar of rolling mill cooling device of the combination that the scope of application is extensive.
Technical scheme of the present invention is following:
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, and 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 said 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 through flange respectively, and swivelling pipe is provided with nozzle.
Said swivel joint is fixedly connected with vertical outside water pipe of frame cooling water pipe through flange.
The interspersed inside that is arranged on swivel joint of said vertical outside water pipe, swivel joint realizes that through 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 through rolling bearing between inner core pipe and the overcoat, guarantee that through dedicated sealing member medium does not have leakage.Rotate swivelling pipe, the driven rotary joint rotates, adjust the spray angle of nozzle after, can through 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 said 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 through flange respectively, and swivelling pipe is provided with nozzle.
The interspersed inside that is arranged on swivel joint of said vertical water pipe, swivel joint realizes that through rolling bearing movable sealing is connected with vertical water pipe; Be provided with alignment pin at vertical water pipe and swivel joint.
The invention has the advantages that:
The present invention adopts the frame cooling water pipe of band swivel joint, can be according to mill milling pass size, change the spray angle of cooling water through the adjustment swivelling pipe, and different collars are effectively cooled off, do not receive the space constraints of other equipment such as frame.The present invention can realize 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 present invention is reasonable in design, and is safe and convenient to use.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further specified, but be not limited thereto.
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, and 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 said 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 through flange respectively, and swivelling pipe 2 is provided with nozzle 3.
Said swivel joint 1 is fixedly connected with vertical outside water pipe 7 of frame cooling water pipe through flange.
The vertical perforation is provided with many vertical water pipes 8 between the lateral outer side water pipe 6 of said frame cooling water pipe.
The course of work:
According to the structure of rolling-mill housing, the present invention is tilted to place.
According to the anglec of rotation that the size and the position of collars is provided with swivelling pipe 2 of the present invention 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.
Cooling water gets into the frame cooling water pipe through water pipe 9, and cooling water sprays to collars 4 through the nozzle on the frame cooling water pipe 3, and collars 4 is cooled off, and in this simultaneously, cooling water also sprays to collars 4 through the nozzle on the swivelling pipe 23, and collars 4 is cooled off.
When the size of roll collars 4 becomes big or diminishes; Operating personnel are according to the swivelling pipe 2 between two swivel joints 1 of width adjusting of different rolling groove collars; Remove the alignment pin of swivel joint 1, rotation swivelling pipe 2 makes cooling water cover collars 4 width fully; Fixedly swivelling pipe 2 of alignment pin is passed through in the adjustment back, can get into normal rolling shedule behind the connection cooling water.
