[0002] As an important part of the finishing mill, the finishing mill trolley roller is mainly used to roll metal materials to achieve the required shape and size. The finishing mill trolley roller is usually made of high-strength wear-resistant materials with high hardness and good wear resistance. During the operation of the finishing mill trolley, the roller will be subjected to high-intensity pressure and friction, causing the temperature of the roller to rise rapidly. If the roller temperature is too high, the roller surface will be oxidized, worn and deformed, affecting the rolling quality of the product and the service life of the roller. Therefore, the roller needs to be cooled.

[0003] In the prior art, cooling water is generally sprayed on the surface of the roller through a horizontally arranged spray pipe to achieve cooling. However, the existing spray pipes are mostly distributed along the axial direction of the roller. When cooling water is sprayed on the roller, only a local position of the roller can be sprayed, which not only wastes water resources but also has a poor cooling effect. Utility Model Content

The adjustable cooling device for the rollers of the finishing mill trolley comprises a water collecting tank 1, an arc-shaped spraying frame 2 and a water filter plate 3. The water collecting tank 1 has an upward opening. The arc-shaped spraying frame 2 is mounted on the opposite side edges of the water collecting tank 1. The arc-shaped spraying frame 2 is provided with spray holes 23 opening upward. The arc-shaped spraying frame 2 can be parallel to the lower peripheral wall of the roller to spray cooling water to the peripheral wall of the roller. The water filter plate 3 is arranged in the water collecting tank 1 to filter the waste water sprayed on the roller.

[0027] The present embodiment provides an adjustable cooling device for the rollers of the finishing mill trolley. Compared with the prior art, the present embodiment provides an adjustable cooling device for the rollers of the finishing mill trolley. The arc-shaped spray frame 2 is installed above the water collecting tank 1. The arc-shaped spray frame 2 can be adapted to the curvature of the outer circumference of the roller, and can synchronously spray the lower outer circumferential wall of the upper roller, thereby increasing the contact area of ​​the spray and improving the cooling effect on the roller. The water collecting tank 1 is used to receive the waste water after the roller is cooled. The water filter plate 3 arranged inside can filter the waste water after spraying, which is convenient for the subsequent reuse of water resources and avoids the waste of water resources.

[0028] In this embodiment, the external water supply pipe is connected to the water inlet pipe 24 to supply cooling water to the interior of the arc-shaped spray rack 2. The cooling water is sprayed onto the peripheral wall surface of the passing roller through the arc-shaped spray rack 2, thereby cooling the roller. The arc-shaped spray rack 2 is suitable for the curvature of the outer circumference of the roller, and can better spray the cooling water onto the surface of the roller, thereby improving the cooling effect on the roller.

[0029] At the same time, a drainage hole 14 is also provided at the bottom of the water collecting box 1. The drainage hole 14 can be connected to the water response system through a connecting pipe, and can also be connected to the drainage system through a connecting pipe, which facilitates the subsequent treatment of water.

[0030] In one possible implementation, see Figures 1 to 5 The arc-shaped spray rack 2 includes two parallel tubes 21 respectively arranged on the opposite side edges of the water collecting box 1 and a plurality of arc-shaped tubes 22 respectively connected between the two parallel tubes 21. The arc-shaped tubes 22 are arranged to be concave downward in an arc shape. Spray holes 23 for spraying the rollers are respectively provided on the arc-shaped tubes 22 and the parallel tubes 21. The upper edges of the two end surfaces of the water collecting box 1 have the same curvature as that of the arc-shaped tubes 22.

[0031] In this embodiment, when the roller passes over the arc-shaped spray rack 2, cooling water is sprayed on the surface of the roller passing through the two parallel pipes 21 and the plurality of arc-shaped pipes 22, thereby cooling the roller comprehensively. The arc-shaped pipes 22 are in an arc shape, which is suitable for the curvature of the outer circumference of the roller, and can spray cooling water on the surface of the roller more accurately, thereby improving the cooling effect on the roller.

[0032] In one possible implementation, see Figures 1 to 5 Supporting platforms 11 are respectively provided at the four corners of the water collecting box 1 , and the ends of the parallel pipes 21 are respectively connected to the supporting platforms 11 .

[0033] In this embodiment, when the parallel seat is installed, the two ends of the two parallel pipes 21 are supported by the supporting platforms 11 at the four corners of the water collecting box 1, so as to achieve reliable installation of the parallel pipes 21. Specifically, the supporting platform 11 extends toward the axial side of the water collecting box 1 to avoid occupying the external space of the water collecting box 1. The supporting platform 11 can provide a stable installation plane for the ends of the parallel pipes 21, thereby ensuring a good supporting effect.

[0034] In one possible implementation, see Figures 1 to 5 The supporting platform 11 is provided with a mounting rod 12 extending upward, and the end of the parallel tube 21 is provided with a sleeve ring 26 sleeved on the outer periphery of the mounting rod 12.

[0035] In this embodiment, an upwardly extending mounting rod 12 is provided above the supporting platform 11, and the sleeve ring 26 at the end of the parallel tube 21 can be sleeved on the outer periphery of the mounting rod 12, so as to effectively position the horizontal position of the parallel rod and improve the convenience of installation.

[0036] In one possible implementation, see Figures 1 to 5 The mounting rod 12 is provided with a plurality of positioning holes 13 spaced apart in the up-down direction. The positioning holes 13 are provided along the radial direction of the mounting rod 12 and penetrate the mounting rod 12. A positioning pin 15 capable of supporting under the sleeve ring 26 is inserted into the positioning hole 13. The plurality of positioning holes 13 provided on the mounting rod 12 are respectively at different height positions, so as to facilitate the adjustment of the height position of the arc-shaped spray rack 2.

[0037] Specifically, the height of the arc-shaped spray frame 2 can be adjusted according to the change in the diameter of the roll to improve the cooling effect of the structure on the roll. When adjustment is required, the arc-shaped spray frame 2 is manually lifted, and when the sleeve rings 26 set on both sides of the parallel pipe 21 are adjusted to an appropriate height, the positioning pins 15 are inserted into the positioning holes 13 of the corresponding height, and the upper sleeve rings 26 are effectively supported by the positioning effect to ensure the position stability of the arc-shaped spray frame 2.

[0038] In one possible implementation, see Figures 1 to 5 The positioning pin 15 is connected with a supporting arc rod 16 for supporting the bottom of the sleeve ring 26 . The supporting arc rod 16 is arranged around the outer periphery of the mounting rod 12 . The supporting arc rod 16 has a supporting surface 161 supported on the bottom of the sleeve ring 26 .

[0039] In this embodiment, a supporting arc rod 16 is also provided on the positioning pin 15. When the positioning pin 15 is inserted into the corresponding positioning hole 13, the supporting arc rod 16 can be enclosed on the outer periphery of the mounting rod 12, providing a flat supporting surface 161 for the installation of the sleeve ring 26, thereby ensuring the stability of the installation of the arc-shaped spray frame 2 and avoiding shaking, thereby improving the alignment of the arc-shaped spray frame 2 with the peripheral wall of the rolling mill, and enhancing the cooling effect on the rolling mill.

[0040] In one possible implementation, see Figures 1 to 5 One of the parallel pipes 21 is connected to a water inlet pipe 24 , and the other parallel pipe 21 is connected to a water outlet pipe 25 . The water inlet pipe 24 is connected to the water supply pipe through a flexible telescopic pipe 27 .

[0041] In this embodiment, the drain pipe is located at a side away from the water inlet pipe 24, so that water can be drained out by tilting the arc-shaped spray rack 2 during maintenance or non-use. In normal use, the drain pipe is in a blocked state so that the water supplied in the water inlet pipe 24 can be sprayed onto the surface of the roller to achieve effective cooling of the roller.

[0042] The water inlet pipe 24 is connected to a water supply pipe for supplying cooling water via a flexible telescopic pipe 27. The flexible telescopic pipe 27 can be telescopically adjusted according to the distance between the water supply pipe and the water inlet pipe 24, which facilitates structural connection and enhances the versatility of the structure.

[0043] In one possible implementation, see Figures 1 to 5 The middle part of the water collecting box 1 has an upwardly protruding support boss 17, which is located between the two parallel tubes 21 and extends along the axial direction of the parallel tubes 21. The bottom of the water collecting box 1 has a through cavity 18 located below the support boss 17.

[0044] In this embodiment, the support platform provided in the middle of the water collecting box 1 is convexly arranged upwardly in an inverted V shape, which is used to enhance the structural strength of the water collecting box 1. The through cavity 18 at the bottom of the support platform can not only reduce the space occupation, but also save material consumption. Two water filter plates 3 can be provided, and the two water filter plates 3 are respectively located on both sides of the support boss 17, so as to realize the reasonable layout of the space.

[0045] In one possible implementation, see Figures 1 to 5 The side edge of the water filter plate 3 is provided with an upwardly extending hanging member 31, which includes an extending vertical plate 32 attached to the inner side of the side wall of the water collecting box 1 and a hook head 33 connected to the upper end of the extending vertical plate 32, and the hook head 33 can be hooked on the upper edge of the side wall of the water collecting box 1.

[0046] In this embodiment, the hanging member 31 is used to install and limit the water filter plate 3, so that the water filter plate 3 is in the upper space of the water collecting box 1, to prevent the water filter plate 3 from falling into the bottom of the water collecting box 1 and affecting the filtering effect. The extended vertical plate 32 is used to extend to the upper edge of the side wall of the water collecting box 1 to realize the setting of the hook head 33, which extends outward and downward and can be hung on the upper edge of the side wall of the water collecting box 1 to prevent the water filter plate 3 from falling.

[0047] For some examples, see Figures 1 to 5 The outer end of the hook head 33 is provided with a handle 34 bent outward, and the handle 34 is provided with a gripping hole 35 extending horizontally and penetrating from top to bottom. The setting of the handle 34 facilitates the subsequent operator to take the water filter plate 3 out of the water collection box 1, and the setting of the gripping hole 35 improves the convenience of the operator's operation and facilitates the subsequent cleaning of the water filter plate 3.

[0048] The arc-shaped spray frame 2 of the above-mentioned adjustable roller cooling device of the finishing mill trolley is installed above the water collecting tank 1. The arc-shaped spray frame 2 can be adapted to the curvature of the outer circumference of the roller, and can synchronously spray the lower outer circumferential wall of the upper roller, thereby increasing the contact area of ​​the spray and improving the cooling effect on the roller. The water collecting tank 1 is used to receive the waste water after the roller is cooled. The water filter plate 3 arranged inside can filter the waste water after spraying, which is convenient for the subsequent reuse of water resources and avoids the waste of water resources.

[0049] The above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
