Technical Field

[0001] The present invention relates to the technical field of rolling mills, and in particular to a waterproof sealing device and method for medium and thick plate support rollers. Background Art

[0002] The support rolls of the plate mill are key components in the mill system. They are mainly used to support the working rolls, ensuring the rigidity and stability of the roll system during the rolling process, thereby ensuring the dimensional accuracy and surface quality of the rolled products.

[0003] The medium and thick plate hot rolling mill operates in a water-cooled and humid environment all year round. Water vapor entering the support roller bearing seat will cause problems such as oil film bearing rust, lubrication failure, and bearing burning, seriously affecting the stable operation of the rolling mill and the service life of the support roller. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a waterproof sealing device and method for medium and thick plate support rollers.

[0005] In order to solve the above technical problems, the technical solutions of the present invention are as follows: A waterproof sealing device for a medium and thick plate support roller, comprising: A sealing ring is provided between the end face of the support roller and the bearing seat. The sealing ring is annular and sleeved on the outer side of the end face of the support roller; A fixing device is used to fix the sealing ring between the end face of the support roller and the bearing seat, and the fixing device includes a fixing clamp sleeved on the outside of the sealing ring.

[0006] As a preferred solution of the waterproof sealing device for medium and thick plate support rollers of the present invention, the sealing ring is a flexible sealing ring.

[0007] As a preferred solution of the waterproof sealing device for medium and thick plate support rollers of the present invention, the sealing ring is made of rubber.

[0008] As a preferred solution of the waterproof sealing device for medium and thick plate support rollers of the present invention, the width of the sealing ring is equal to the distance between the end face of the support roller and the bearing seat.

[0009] As a preferred solution of the waterproof sealing device for medium and thick plate support rollers of the present invention, the inner diameter of the fixing clamp is smaller than the outer diameter of the sealing ring.

[0010] The present invention further provides a waterproof sealing method for a medium and thick plate support roller, which is based on any of the above-mentioned waterproof sealing devices for medium and thick plate support rollers, comprising: Place the sealing ring between the end face of the support roller and the bearing seat; The fixed clamp is sleeved and clamped on the outer side of the sealing ring.

[0011] The beneficial effects of the present invention are as follows: (1) In the present invention, a sealing ring is arranged between the end face of the roll body of the support roll and the bearing seat, and a fixed clamp is used to fix the sealing ring. The sealing ring can prevent the roll cooling water and water vapor from entering the inside of the bearing seat, thereby significantly improving the waterproof performance of the support roll of the rolling mill, prolonging the service life, reducing the failure rate, and ensuring the smooth progress of production.

[0012] (2) The sealing ring of the present invention is a flexible sealing ring, which has a certain ductility. At the same time, the inner diameter of the fixed clamp is smaller than the outer diameter of the sealing ring. In addition, the width of the fixed clamp is smaller than the width of the sealing ring. When the fixed clamp is clamped on the outer side of the sealing ring, the fixed clamp is located in the middle of the sealing ring. When the fixed clamp applies pressure to the sealing ring, the sealing ring deforms, causing the two sides of the sealing ring to further move towards the end face of the support roll and the end face of the bearing seat, thereby further improving the sealing effect of the sealing ring on the support roll. Description of the Drawings

[0013] In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings required for the description of the embodiments will be briefly introduced below. Obviously, the drawings in the following description are only some embodiments of the present invention. For those of ordinary skill in the art, without creative efforts, other drawings can also be obtained based on these drawings.

[0014] Figure 1 It is a schematic structural diagram of an existing medium and heavy plate support roll.

[0015] Figure 2 It is a schematic structural diagram of the waterproof sealing device for the medium and heavy plate support roll provided by the present invention; Among them: 1. Sealing ring; 2. Fixing device; 3. Support roll; 4. Bearing seat. Detailed Embodiments

[0016] To make the content of the present invention easier to be clearly understood, the present invention will be further described in detail below according to the detailed embodiments and in conjunction with the drawings.

[0017] Figure 2 It is a schematic structural diagram of the waterproof sealing device for the medium and heavy plate support roll 3 provided by the embodiment of the present application. This device includes a sealing ring 1 and a fixing device 2. Among them, the fixing device 2 fixes the sealing ring 1 between the end face of the support roll 3 and the bearing seat 4. The roll cooling water and water vapor are effectively blocked from entering the inside of the bearing seat 4 through the sealing ring 1.

[0018] Specifically, the sealing ring 1 is in an annular shape and is sleeved between the end face of the support roll 3 and the bearing roll. The fixing device 2 includes a fixing clamp which can be sleeved outside the sealing ring 1 to fix the sealing ring 1.

[0019] Preferably, the width of the sealing ring 1 is equal to the distance between the end face of the support roll 3 and the bearing seat 4. In this way, when the sealing ring 1 is sleeved between the end face of the support roll 3 and the bearing seat 4, the side surfaces of the sealing ring 1 are respectively abutted against the end face of the support roll 3 and the end face of the bearing seat 4. In this way, the sealing ring 1 can completely fill the gap between the end face of the support roll 3 and the bearing seat 4, preventing the cooling water and water vapor of the rolling mill from entering the support roll 3 from the edge of the sealing ring 1.

[0020] Furthermore, the sealing ring 1 is a flexible sealing ring 1 with a certain ductility. At the same time, the inner diameter of the fixing clamp is smaller than the outer diameter of the sealing ring 1. In addition, the width of the fixing clamp is smaller than the width of the sealing ring 1. When the fixing clamp is clamped outside the sealing ring 1, the fixing clamp is located in the middle of the sealing ring 1, and the fixing clamp will apply pressure to the sealing ring 1 to cause deformation of the sealing ring 1, so that the two sides of the sealing ring 1 further move towards the end face of the support roll 3 and the end face of the bearing seat 4, thereby further improving the sealing effect of the sealing ring 1 on the support roll 3.

[0021] In this embodiment, the sealing ring 1 is made of rubber.

[0022] It should be noted that there are two sealing rings 1, and the two sealing rings 1 are respectively arranged between the end face of the support roll 3 and the two bearing seats 4. Correspondingly, there are also two fixing clamps, and the two fixing clamps are respectively clamped outside the two sealing rings 1.

[0023] The embodiment of the present application also provides a waterproof sealing method for the medium-thick plate support roll 3, which is based on the above-mentioned waterproof sealing device for the medium-thick plate support roll 3. The method specifically includes the following steps: Step S101: Set the sealing ring 1 between the end face of the support roll 3 and the bearing seat 4; Step S102: Sleeve and clamp the fixing clamp outside the sealing ring 1.

[0024] Thus, the technical solution of the present application sets the sealing ring 1 between the roll body end face of the support roll 3 and the bearing seat 4, and uses a fixing clamp to fix the sealing ring 1. The sealing ring 1 can prevent the cooling water and water vapor of the rolling mill from entering the inside of the bearing seat 4, thereby significantly improving the waterproof performance of the rolling mill support roll 3, extending the service life and reducing the failure rate, and ensuring the smooth progress of production.

[0025] In addition to the above embodiments, the present invention can also have other implementation manners; all technical solutions formed by equivalent replacement or equivalent transformation fall within the protection scope required by the present invention.
