[0052] The inner guard plate, the middle guard plate and the outer guard plate of the utility model constitute a "stacked type" guard plate structure, are arranged in sequence from the outside to the inside according to the area size of each layer of guard plate (the inner side is close to the roll shifting device 3, the outer layer guard plate area is large, and the inner layer guard plate area is small), and are mutually stacked, so as to ensure that the adjacent guard plates can be in sealing contact and can slide with each other.

When the first limiting plate 13 of the middle guard plate (the outermost middle guard plate) adjacent to the outer guard plate 11 abuts against the third limiting plate 112 of the outer guard plate 11, the movement to the operation side is completed; the roll shifting device 3 moves by the roll shifting under the action of the working roll hydraulic cylinder; when the hydraulic cylinder is stretched to the limit position, the inner guard plate 12 and the middle guard plates move to the limit position close to the operation side.

[0056] Further, as shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 shown, the intermediate guard plate is provided with a fourth limiting plate 14 on the side close to the transmission side; the inner guard plate 12 is provided with a fifth limiting plate 122 on the side close to the transmission side, and the outer guard plate 11 is provided with a sixth limiting plate 113 on the side close to the transmission side; the fifth limiting plate 122 of the inner guard plate 12 can abut on the fourth limiting plate 14 of the adjacent intermediate guard plate (the innermost intermediate guard plate) to drive the adjacent intermediate guard plate to move to the transmission side.

The roll shifting device 3 is moved by the roll shifting of the hydraulic cylinder of the work roll, and when the hydraulic cylinder is retracted to the limit position, the inner guard plate 12 and the intermediate guard plates move to the limit position close to the transmission side.

[0057] The intermediate guard plate and the inner guard plate 12 are provided with limiting plates on both sides, and when the moving guard plate reaches the limit position, the adjacent next guard plate (located on the operation side or the transmission side) is driven to continue to move until the roll shifting distance is completed.

[0062] As shown in Figure 6 , the utility model also provides a roll shifting device, and the side of the roll shifting device is provided with the push-pull type water baffle cover.

[0063] Example 1

[0064] As shown in Figure 1As shown, the number of the intermediate guard plates of the push-pull type water blocking cover of the roll shifting device is greater than or equal to 2 (the number is determined according to actual requirements, including but not limited to 2 intermediate guard plates), and each intermediate guard plate is arranged and stacked between the inner guard plate 12 and the outer guard plate 11 in sequence.

[0065] Further, the first limiting plate 13 of an intermediate guard plate can be slidably abutted on the first limiting plate 13 of the adjacent intermediate guard plate close to the operation side to drive the adjacent intermediate guard plate to move towards the operation side.

[0066] Further, the fourth limiting plate 14 of an intermediate guard plate can be slidably abutted on the fourth limiting plate 14 of the adjacent intermediate guard plate close to the transmission side to drive the adjacent intermediate guard plate to move towards the transmission side.

[0067] Specifically, as shown, Figure 1 the number of the intermediate guard plates is 2, the intermediate guard plate close to the operation side is set as the first intermediate guard plate 15, and the intermediate guard plate close to the transmission side is set as the second intermediate guard plate 16.

[0068] Then, the outer guard plate 11, the first intermediate guard plate 15, the second intermediate guard plate 16 and the inner guard plate 12 jointly constitute a "stacked type" guard plate structure, and the opening distance (the size of the opening slot) of each guard plate and the position of the limiting plate (the first limiting plate 13 and the fourth limiting plate 14) are set according to the characteristics of the roll shifting device and the roll shifting distance. The outer guard plate 11 is installed at the outermost side of the water blocking cover and is fixed on the roll shifting frame 31 by using bolts; the inner guard plate 12 is installed at the innermost side of the water blocking cover and is fixed on the moving block 32 by using connecting bolts, and the second intermediate guard plate 16 and the first intermediate guard plate 15 are arranged and stacked between the inner guard plate 12 and the outer guard plate 11 in sequence.

[0069] When the work roll shifts from the transmission side to the operation side, the push-pull type water blocking cover of the roll shifting device operates as follows:

[0070] As shown, Figure 7As shown, the inner guard plate 12 follows the moving block 32 to move towards the operation side, and stops relative movement after the second limiting plate 121 (the limiting plate on the operation side) on the inner guard plate 12 moves and hits the first limiting plate 13 (the limiting plate on the operation side) on the second intermediate guard plate 16, the inner guard plate 12, the second intermediate guard plate 16 continue to move forward, and stops relative movement after the first limiting plate 13 (the limiting plate on the operation side) on the second intermediate guard plate 16 moves and hits the first limiting plate 13 (the limiting plate on the operation side) on the first intermediate guard plate 15, the inner guard plate 12, the second intermediate guard plate 16, the first intermediate guard plate 15 continue to move forward, and stops movement after the first limiting plate 13 (the limiting plate on the operation side) on the first intermediate guard plate 15 moves and hits the third limiting plate 112 (the limiting plate on the operation side) on the outer guard plate 11. The above process is the overall movement process of the push-pull type water baffle, and after reaching the specified roll shifting position, movement can be stopped.

[0071] On the contrary, as Figure 8 As shown, when the work roll shifts from the operation side to the transmission side, the push-pull type water baffle of the roll shifting device of the utility model operates as follows:

[0072] The inner guard plate 12 follows the moving block 32 to move towards the transmission side, and stops relative movement after the fifth limiting plate 122 (the limiting plate on the transmission side) on the inner guard plate 12 moves and hits the fourth limiting plate 14 (the limiting plate on the transmission side) on the second intermediate guard plate 16, the inner guard plate 12, the second intermediate guard plate 16 continue to move forward, and stops relative movement after the fourth limiting plate 14 (the limiting plate on the transmission side) on the second intermediate guard plate 16 moves and hits the fourth limiting plate 14 (the limiting plate on the transmission side) on the first intermediate guard plate 15, the inner guard plate 12, the second intermediate guard plate 16, the first intermediate guard plate 15 continue to move forward, and stops movement after the fourth limiting plate 14 (the limiting plate on the transmission side) on the first intermediate guard plate 15 moves and hits the sixth limiting plate 113 (the limiting plate on the transmission side) on the outer guard plate 11. The above process is the overall movement process of the push-pull type water baffle, and after reaching the specified roll shifting position, movement can be stopped.

[0073] As described above, the push-pull type water baffle of the roll shifting device of the utility model has the following beneficial effects:

[0074] The inner guard plate, the intermediate guard plate and the outer guard plate of the utility model form a "stacked type" guard plate structure, and are arranged from outside to inside in order and stacked with each other according to the area size of each layer of guard plate, so that the adjacent guard plates can be in sealed contact and slide with each other. The inner guard plate and each intermediate guard plate move and expand or shrink under the driving of the moving block to complete the roll shifting distance, so as to dynamically and timely seal and shield the outer opening groove, that is, to comprehensively protect the water inlet area of the roll shifting device.

[0075] The utility model solves the problem that a large amount of cooling water enters the roll shifting device during rolling, improves the equipment operation environment, and prolongs the service life of the equipment.

[0076] The utility model discloses simple and reliable structure, and the low cost of input, and easy maintenance.

[0077] The above merely illustrates the specific implementation of the utility model, and is not used to limit the range of the utility model. Any equivalent change and modification made by any person skilled in the art without departing from the concept and principle of the utility model shall belong to the range of the utility model protection.
