[0027] To solve the technical problems in the background art, as shown in Figures 1-4 The present application provides a technical solution: a new vertical roller structure for a hydraulic deviation correction device, characterized by:

[0028] The conical table 1 is a conical structure with a larger bottom and a smaller top, and a through hole 2 is provided inside. The bottom of the conical table 1 is provided with an annular connecting piece 3 for connection and fixation with other components. Limiting holes 4 are provided on the side wall of the conical table 1 for inserting positioning pins 11. The outer ring of the bearing seat 5 is fixedly connected with the conical table 1 to ensure its stability. The inner ring of the bearing seat 5 is connected with a stepped nut column 6. The smaller diameter end of the stepped nut column 6 extends into the inner ring of the bearing seat 5, and the other end side wall is provided with a plurality of wrench columns 7 in the radial direction, which is convenient for manual adjustment. The adjusting screw 8 is connected with the stepped nut column 6 through threads. The top end of the adjusting screw 8 is fixedly connected with the mounting plate 9 for mounting other components. The side wall of the adjusting screw 8 is provided with a groove 10 parallel to the axial direction for the insertion of the positioning pin 11. The groove 10 can be provided with one, two or even more. After the positioning pin 11 is inserted into the limiting hole 4, it is clamped in the groove 10 to limit the rotation of the adjusting screw 8 and ensure its stability. The bottom of the bearing 12 is fixedly connected to the mounting plate 9. The top of the bearing 12 is provided with a bearing end 13, and the axis of the bearing end 13 is vertically arranged. The vertical roller 14 is inserted into the bearing end 13, and the axis of the vertical roller 14 is collinear with the axis of the bearing end 13 to ensure the stable rotation of the vertical roller 14.

[0029] Further, the through hole 2 inside the conical table 1 is coaxial with the center axis of the stepped nut column 6, that is, the two are coaxially arranged. This design ensures that the adjusting screw 8 can accurately pass through the through hole 2 of the conical table 1 and tightly match with the threaded part of the stepped nut column 6 during assembly. The through hole 2 is cylindrical, and its diameter is slightly larger than the outer diameter of the adjusting screw 8 to ensure that the adjusting screw 8 can smoothly slide in the through hole 2. The depth of the through hole 2 penetrates through the entire conical table 1, extending from the top to the bottom, providing enough space for the adjusting screw 8 to move. The coaxial arrangement of the through hole 2 and the stepped nut column 6 ensures the accurate positioning of the adjusting screw 8 during assembly, reduces assembly errors, and improves the assembly accuracy of the entire vertical roller structure. This design makes the adjusting screw 8 stable during extension and retraction, avoiding shaking or wear caused by eccentricity, thereby prolonging the service life of the vertical roller structure.

[0030] It should be noted that the through hole 2 is adapted to the inner diameter of the adjusting screw 8, and the inner diameter of the through hole 2 should be slightly larger than the outer diameter of the adjusting screw 8 to ensure that the adjusting screw 8 can be inserted and rotated smoothly, while avoiding excessive gap leading to unstable assembly. According to the mechanical design standard, the diameter of the through hole 2 is usually 0.5 to 1.5 pitches larger than the outer diameter of the bolt or screw.

[0031] It is worth noting that the conical table 1 adopts a double-layer structure design, including an outer layer and an inner layer. The outer layer is mainly used to provide structural strength and stability, while the inner layer is provided with through holes 2 for accommodating the adjusting screw 8. This double-layer structure design can effectively enhance the overall strength of the conical table 1, while providing precise guidance for the adjusting screw 8. The double-layer structure can be achieved by welding, bolting or one-piece forming. The double-layer structure design significantly improves the anti-deformation ability of the conical table 1, especially when subjected to large loads, it can maintain stable performance.

[0032] It should be noted that the limiting hole 4 penetrates through the inner and outer layers of the conical table 1, extending from the outer layer surface to the inner layer, ensuring that the positioning pin 11 can be smoothly inserted and fixed to the position of the adjusting screw 8. The inner diameter of the limiting hole 4 needs to be designed to match the outer diameter of the positioning pin 11, usually with a small gap to ensure that the positioning pin 11 can be smoothly inserted and removed.

[0033] It should be noted that the rib plate 15 is arranged on the side wall of the bearing with seat 12, and connects the bottom wall of the bearing with seat 12 and the bearing end 13, for enhancing the overall structural strength of the bearing with seat 12. The design of the rib plate 15 can effectively disperse the load and reduce stress concentration, thereby improving the stability and service life of the bearing with seat 12. The rib plate 15 can be fixed on the side wall of the bearing with seat 12 by welding or one-piece forming connection.

[0034] It is worth noting that the design of the wrench column 7 is to facilitate the rotation operation of the stepped nut column 6 by using tools such as wrenches or special rotating tools. By rotating the stepped nut column 6, the extension of the adjusting screw 8 can be realized, thereby adjusting the height of the vertical roller 14 to adapt to different working conditions. The number of wrench columns 7 is not less than two, usually evenly distributed on the outer side wall of the stepped nut column 6. The design of multiple wrench columns 7 allows the operator to operate from different angles, reducing the difficulty of operation due to space limitations.

[0035] It should be noted that the bottom of the conical table 1 is provided with a ring-shaped connecting piece 3, which mainly functions to provide a stable mounting platform for fixing the conical table on the base of the hydraulic deviation correcting device. The ring-shaped connecting piece 3 is evenly distributed with multiple mounting holes, which are used to firmly fix the conical table 1 on the base through bolts. The number and size of the mounting holes are designed according to actual needs, usually not less than three to ensure the stability and reliability of the connection.

[0036] Although embodiments of the present application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the application, the scope of which is defined by the appended claims and their equivalents.
