Detailed Implementation

[0028] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] refer to Figure 1-5 An extension device for a dewatering bracket is provided on a dewatering bracket 5. It includes two extension components 1, two positioning bearing sleeves 2, a roll stop 3, and a locking component 4. The two extension components 1 are symmetrically arranged on both sides of the dewatering bracket 5, providing support and guidance for the installation and movement of the positioning bearing sleeves 2. A dewatering roller 6 is provided between the two positioning bearing sleeves 2, and the positioning bearing sleeves 2 can roll on the extension components 1. The positioning bearing sleeves 2 are made of wear-resistant cast iron and can be interference-fitted with the bearings, facilitating the installation and disassembly of the dewatering roller 6. This is prior art and will not be described in detail here. The roll stop 3 is located at one end of the extension component 1 to limit the rolling range of the positioning bearing sleeve 2 and prevent it from falling off the extension component 1. The locking component 4 is located at the end of the extension component 1 away from the roll stop 3, which can fix the positioning bearing sleeve 2 on the extension component 1 and ensure the stability of the dewatering roller 6 during operation.

[0030] In some embodiments, the extension assembly 1 includes an extension plate 11, a limiting groove 12, and a rolling groove 13. The extension plate 11 is located on one side of the dewatering bracket 5 and can be fixed by bolts, providing an installation base for other components. The extension plate 11 can be made of high-strength alloy steel to ensure load-bearing capacity. The length and width of the extension plate 11 can be designed according to the size of the dewatering bracket 5 and the installation requirements of the dewatering roller 6 to ensure that it can meet the actual use needs. The limiting groove 12 is located at the end of the extension plate 11 away from the anti-rolling member 3. A positioning bearing sleeve 2 is provided in the limiting groove 12. The shape and size of the limiting groove 12 match the positioning bearing sleeve 2, which can play a certain limiting role for the positioning bearing sleeve 2 and prevent it from shifting during rolling. The rolling groove 13 is located on the top of the extension plate 11 and is connected to the limiting groove 12. The positioning bearing sleeve 2 can roll on the rolling groove 13. The surface of the rolling groove 13 is smooth, which can reduce the friction of the positioning bearing sleeve 2 when rolling, so that the positioning bearing sleeve 2 can move easily on the extension plate 11. The width and depth of the rolling groove 13 are designed according to the dimensions of the positioning bearing sleeve 2 to ensure that the positioning bearing sleeve 2 can roll smoothly within the rolling groove 13. The outer diameter of the positioning bearing sleeve 2 is adapted to the rolling groove 13 and the limiting groove 12, so that it can roll and be positioned on the extension assembly 1.

[0031] In some embodiments, the locking assembly 4 includes a locking buckle 41, a locking screw 42, and a locking nut 47. The top of the locking buckle 41 is hinged to the extension plate 11 and pressed onto the positioning bearing sleeve 2. The locking buckle 41 and the extension plate 11 can be connected by a pin, allowing the locking buckle 41 to rotate around the pin, facilitating the pressing and releasing operations of the positioning bearing sleeve 2. The locking screw 42 is located on the extension plate 11 and passes through the locking buckle 41. One end of the locking screw 42 can be connected to the extension plate 11, and the other end passes through the locking buckle 41 and is screwed into the locking nut 47. By rotating the locking nut 47, the connection and separation between the bottom of the locking buckle 41 and the extension plate 11 can be realized. At the same time, the pressing force of the locking buckle 41 on the positioning bearing sleeve 2 can be adjusted, thereby fixing the positioning bearing sleeve 2 on the extension plate 11.

[0032] In some embodiments, the locking assembly 4 further includes a locking block 43, which is disposed on the extension plate 11. The locking block 43 and the extension plate 11 can be fixed by welding or bolt connection to ensure the stability of its position. It is also connected to the end of the locking screw 42 away from the locking nut 47. The locking block 43 can fix the locking screw 42 on the extension plate 11.

[0033] In some embodiments, the locking assembly 4 further includes a locking groove 44, which is located at the bottom of the locking buckle 41, and a locking screw 42 passes through the locking groove 44. The width of the locking groove 44 may be greater than the diameter of the locking screw 42 but smaller than the diameter of the head of the locking screw 42, so that the locking screw 42 can pass through the locking groove 44 and lock the locking buckle 41 through the locking nut 47, thereby achieving the pressing of the positioning bearing sleeve 2.

[0034] In some embodiments, the locking assembly 4 further includes a positioning block 45 and a rotating groove 46. The positioning block 45 is disposed on the extension plate 11 and can position and support the locking block 43. The rotating groove 46 is disposed at the bottom of the positioning block 45, and the locking block 43 is rotatably disposed in the rotating groove 46. The shape and size of the rotating groove 46 match the locking block 43, so that the locking block 43 can rotate freely in the rotating groove 46, thereby ensuring that the locking screw 42 can smoothly fix the locking buckle 41.

[0035] In some embodiments, the locking buckle 41 can be a Z-shaped block, which allows the locking buckle 41 to rotate while simultaneously pressing the positioning bearing sleeve 2, thereby providing a stable pressing effect.

[0036] In some embodiments, the anti-roll member 3 may be a baffle vertically disposed on the extension plate 11. The height of the anti-roll member 3 is designed according to the size of the positioning bearing sleeve 2, which can effectively block the positioning bearing sleeve 2 and prevent it from falling off one end of the extension assembly 1 during rolling. The anti-roll member 3 and the extension plate 11 may be fixed by welding or bolting, or they may be integrally formed to ensure the firmness and stability of their connection.

[0037] The specific working principle is as follows:

[0038] During normal operation of the dewatering equipment, the dewatering roller 6 rotates stably on the extension assembly 1 via the positioning bearing sleeve 2. When the bearing needs repair or replacement, loosen the locking nut 47 to release the locking buckle 41. The locking buckle 41 can then be rotated and lifted, relieving the pressure on the positioning bearing sleeve 2. The positioning bearing sleeve 2 rolls out on the rolling groove 13, and the bearing is removed for repair or replacement. Then, a new bearing is installed into the positioning bearing sleeve 2. Bearing replacement is a current technology and will not be described in detail here. Roll the positioning bearing sleeve 2 back into the limiting groove 12, rotate the locking buckle 41 in the opposite direction so that the locking buckle 41 fits against the positioning bearing sleeve 2, rotate the locking block 43 so that the locking screw 42 passes through the locking groove 44, and tighten the locking nut 47 to fix the locking buckle 41, thereby fixing the positioning bearing sleeve 2 and completing the bearing replacement.

[0039] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
