Description

Technical Field

[0001] This invention relates to the field of positioning and installation technology for embedded parts in rolling mill foundations, and in particular to an adjustable positioning bracket for embedded parts in vertical rolling mill foundations and its usage method. Background Technology

[0002] In the construction of heavy metallurgical equipment, the construction of the vertical rolling mill foundation is a core link in ensuring the stable operation of the rolling production line, and the installation and positioning of the foundation embedded parts is a key process. As the benchmark for the installation of rolling mill equipment, the positioning accuracy of the embedded parts directly determines the alignment accuracy of the rolling mill installation, which in turn affects the stability of the production line operation and the product processing accuracy. With the increasing demands for product precision in the metallurgical industry, the requirements for the installation accuracy of embedded parts in the vertical rolling mill foundation are becoming increasingly stringent.

[0003] In traditional construction, workers will make simple temporary supports on site according to the design dimensions of the embedded parts, fix the supports to the surrounding concrete columns or foundation steel bars by welding, place the embedded parts in the preset positions of the supports and spot weld them for initial fixation, and then use measuring tools to check whether the position of the embedded parts meets the design requirements.

[0004] However, this method has obvious drawbacks. On the one hand, the operation process is cumbersome. If a deviation in the position of the embedded part is found, the welding points must be removed one by one, adjusted, and re-welded. The repeated measurement, disassembly, and re-welding operations not only require high technical skills from personnel but also significantly lengthen the installation cycle and slow down the construction progress. On the other hand, the temporary support lacks a precise micro-adjustment structure. After welding, only rough adjustments can be made by tapping and prying, which cannot achieve millimeter-level precise micro-adjustment. Moreover, welding stress can easily cause deformation of the support or embedded part. Ultimately, the positioning accuracy of the embedded part cannot meet the high precision requirements of the vertical rolling mill foundation, and deviations often exceed the standard, affecting the subsequent installation of the rolling mill.

[0027] S7: Carry out the work of fixing and installing the foundation embedded parts.

[0028] The present invention has the following beneficial effects:

Detailed Implementation

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] Example 1

[0042] Reference Figure 1-6 An adjustable positioning bracket for embedded parts in vertical rolling mill foundations includes a positioning module 1, an L-shaped gripper 2, and a clamping module 3.

[0043] Positioning module 1 is located at the center of the device. Positioning module 1 is the core adjustment component of the entire support, which can provide a stable and adjustable installation benchmark for the foundation embedded parts. Positioning module 1 includes a mounting frame 11, which has a through cavity that provides sufficient space for the installation and movement of internal components. A positioning frame 12 is set inside the mounting frame 11. The positioning frame 12 is used to directly support and fix the foundation embedded parts of the vertical rolling mill, ensuring the accuracy of the embedded parts installation position. The positioning frame 12 has a through cavity that facilitates the smooth insertion and positioning of the foundation embedded parts. An adjustment component is set between the mounting frame 11 and the positioning frame 12. The adjustment component can realize multi-directional adjustment of the positioning frame 12 to meet the positioning requirements of different installation scenarios.

[0044] Clamping modules 3 are provided on both the upper and lower sides of the mounting frame 11. The clamping modules 3 are used to firmly fix the entire bracket to the concrete column, thereby improving the stability of the bracket installation. The clamping module 3 includes a mounting plate 31, which has a cavity that runs horizontally from left to right, providing installation and movement space for the internal clamping transmission components. The mounting plate 31 is equipped with a clamping assembly, which can realize the synchronous opening and closing of the L-shaped jaws 2 to adapt to concrete columns of different sizes.

[0045] Each mounting plate 31 has an L-shaped gripper 2 at both ends. The L-shaped gripper 2 adopts an L-shaped structure design, which can fit the corner of the concrete column to achieve stable clamping. The tail end of the long side of the L-shaped gripper 2 is fixedly connected to the clamping component. The clamping component drives the gripper to complete the clamping and releasing action.

[0046] Example 2

[0047] Based on Embodiment 1, the adjustment component of the positioning module 1 includes an adjustment part and a guide part. The adjustment part is responsible for providing the power for the movement of the positioning frame 12, while the guide part ensures the smoothness and accuracy of the movement of the positioning frame 12, avoiding deviation and jamming. The adjustment part is provided on the lower and left sides of the positioning frame 12, and the guide part is provided on the upper and right sides of the positioning frame 12. The adjustment part and the guide part cooperate with each other to achieve precise control of the positioning frame 12. The adjustment part includes a horizontal adjustment screw 13 and a vertical adjustment screw 14. The horizontal adjustment screw 13 is used to control the left and right horizontal displacement of the positioning frame 12, and the vertical adjustment screw 14 is used to control the up and down vertical displacement of the positioning frame 12. The guide part includes a vertical guide post 15 and a horizontal guide post 16. The vertical guide post 15 cooperates with the vertical adjustment screw 14 to achieve the vertical guidance limit, and the horizontal guide post 16 cooperates with the horizontal adjustment screw 13 to achieve the horizontal guidance limit.

[0048] The lateral adjusting screw 13 passes through the left side wall of the mounting frame 11 and is threaded into the left side wall of the mounting frame 11. The threaded structure allows for precise distance adjustment by turning the screw. The tail end of the lateral adjusting screw 13 slides into the left side of the positioning frame 12. The sliding engagement reduces frictional resistance during adjustment and makes the adjustment operation smoother. The longitudinal adjusting screw 14 passes through the bottom of the mounting frame 11 and is threaded into the bottom of the mounting frame 11. Similarly, stable longitudinal adjustment is achieved through threaded transmission. The tail end of the longitudinal adjusting screw 14 slides into the bottom surface of the positioning frame 12 to ensure smooth longitudinal adjustment. The longitudinal guide post 15 penetrates the top of the mounting frame 11 and slides in engagement with the top of the mounting frame 11. The sliding engagement does not affect the up and down movement of the positioning frame 12, and at the same time serves as a limiting guide. The tail end of the longitudinal guide post 15 slides in engagement with the upper surface of the positioning frame 12, further enhancing the stability of the longitudinal guidance. The transverse guide post 16 penetrates the right side wall of the mounting frame 11 and slides in engagement with the right side wall of the mounting frame 11, providing reliable guidance for transverse movement. The tail end of the transverse guide post 16 slides in engagement with the right side of the positioning frame 12, ensuring no deviation during transverse adjustment.

[0049] Guide rails 17 are provided on the top, bottom, left, and right outer surfaces of the positioning frame 12. The guide rails 17 provide a standardized sliding track for the movement of the positioning frame 12, improving the adjustment accuracy. The guide rails 17 on the top and bottom outer surfaces are oriented horizontally to accommodate the lateral movement of the positioning frame 12. The guide rails 17 on the left and right outer surfaces are oriented vertically to accommodate the longitudinal movement of the positioning frame 12. The guide rails 17 have inverted T-shaped grooves along their length. The structure of the T-shaped grooves prevents the slider 18 from falling off, ensuring the firmness of the sliding connection. The slider 18 is provided in the T-shaped grooves and can slide freely within the T-shaped grooves, transmitting the adjustment and guiding forces. The slider 18 slides smoothly and without jamming through the T-shaped grooves and guide rails 17. The tail end of the lateral adjusting screw 13 is rotatably connected to the slider 18 on the left side of the positioning frame 12. This rotatable connection avoids torque interference when the screw is turned. The lateral adjusting screw 13 and the slider 18 are fixed in the axial direction to prevent the screw from separating from the slider during adjustment and to ensure the effectiveness of transmission. The tail end of the longitudinal adjusting screw 14 is rotatably connected to the slider 18 on the bottom surface of the positioning frame 12, thus achieving torque-free longitudinal transmission. The longitudinal adjusting screw 14 and the slider 18 are fixed in the axial direction to ensure the stability of longitudinal adjustment. The tail end of the longitudinal guide post 15 is fixedly connected to the slider 18 on the top surface of the positioning frame 12. This fixed connection allows the guide post to move synchronously with the positioning frame 12, achieving precise guidance. The tail end of the lateral guide post 16 is fixedly connected to the slider 18 on the right side of the positioning frame 12, completing a stable connection for lateral guidance.

[0050] The clamping module 3 is fixedly connected to the mounting frame 11 via the mounting plate 31. This fixed connection enhances the overall structural strength and prevents loosening during use. The clamping assembly includes a transmission gear 32, which is the core component of the clamping transmission and enables bidirectional power transmission. The transmission gear 32 is rotatably connected to the middle section of the front and rear inner sidewalls of the mounting plate 31. This rotatable connection allows the transmission gear 32 to rotate flexibly, ensuring transmission efficiency. An upper rack 33 meshes with the upper part of the transmission gear 32. The lower part of the 2 has a lower rack 34 engaged with it. The gear and rack meshing transmission method has high precision and large transmission force. The upper rack 33 and the lower rack 34 are both horizontally arranged in the mounting plate 31. The horizontal arrangement is adapted to the lateral opening and closing requirements of the gripper. The cross-section of the upper rack 33 and the lower rack 34 is T-shaped. The T-shaped cross-section can prevent the rack from falling out in the mounting plate 31 and improve the running stability. The upper rack 33 and the lower rack 34 are both in sliding fit with the inner side wall of the mounting plate 31. The sliding fit allows the rack to move smoothly without jamming.

[0051] A connecting lug 35 is provided on the rear outer side of the mounting plate 31. The connecting lug 35 provides a fixed mounting base for the connecting screw 37. A sliding groove is provided on the rear side of the mounting plate 31. The sliding groove provides a channel for the movement of the connecting parts and avoids movement interference. A connecting lug 36 is fixedly connected to the tail end of the upper rack 33. The connecting lug 36 is used to transmit the power of the connecting screw 37 to drive the upper rack 33 to move. The connecting lug 36 slides with the mounting plate 31 through the sliding groove to ensure that the connecting lug 36 can move smoothly with the rack. A connecting screw 37 is provided between the connecting lug 35 and the connecting lug 36. The connecting screw 37 provides manual adjustment power for the clamping action. The operation is simple and convenient. The connecting screw 37 passes through the connecting lug 35 and is threaded with the connecting lug 35. The threaded transmission can realize precise adjustment of the clamping force. The tail end of the connecting screw 37 is rotatably connected to the connecting lug 36. The connecting screw 37 and the connecting lug 36 are axially fixed to prevent the screw from disengaging from the connecting lug and ensure that the clamping adjustment is continuously effective.

[0052] The L-shaped gripper 2 includes an L-shaped connecting block 21, which is the main connecting component of the gripper, ensuring a stable connection between the gripper and the transmission component. The L-shaped gripper 2 slides with the mounting plate 31 through the L-shaped connecting block 21. This sliding connection allows the gripper to open and close flexibly, adapting to columns of different sizes. The L-shaped gripper 2 on the left side of the mounting plate 31 is fixedly connected to the head end of the upper rack 33 through the L-shaped connecting block 21. The movement of the upper rack 33 drives the left gripper to move. The L-shaped gripper 2 on the right side of the mounting plate 31 is fixedly connected to the tail end of the lower rack 34 through the L-shaped connecting block 21. The movement of the lower rack 34 drives the right gripper to move. The synchronous transmission of the gear and rack allows the left and right grippers to open and close simultaneously, achieving symmetrical clamping.

[0053] The short end of the L-shaped connecting block 21 is provided with an end clamping block 22, which directly contacts the concrete column, increasing the contact area and stability of the clamping. An installation groove 221 is formed on the inner side of the end clamping block 22, providing installation space for the internal elastic components and ensuring structural compactness. A clamping plate 23 slides within the installation groove 221, allowing for slight movement within the groove to achieve flexible clamping in conjunction with the elastic components. The clamping plate 23 and the installation groove 221... Multiple springs 25 are evenly distributed between the bottom surfaces to provide uniform elastic preload. One end of each spring 25 is fixedly connected to the bottom surface of the mounting groove 221, and the other end is fixedly connected to the clamping plate 23. The fixed connection ensures stable transmission of the spring force. A pressing plate 24 is provided on the side of the clamping plate 23 facing away from the mounting groove 221. The pressing plate 24 directly contacts the concrete column. The pressing plate 24 is elastic, and the elastic material can prevent damage to the column surface during clamping, while improving the clamping fit and anti-slip properties.

[0054] Multiple reinforcing ribs 4 are provided at the connection between the mounting frame 11 and the mounting plate 31. The multiple reinforcing ribs 4 are evenly distributed at the connection position, which can greatly improve the connection strength between the mounting frame 11 and the mounting plate 31, prevent deformation and breakage at the connection after long-term use, enhance the structural stability of the entire positioning bracket, extend the service life of the equipment, and ensure the safety of the installation process of the vertical rolling mill foundation embedded parts.

[0055] Example 3

[0056] To further illustrate the above embodiments, the present invention also provides a method for using an adjustable positioning bracket for embedded parts in a vertical rolling mill foundation, the specific steps of which are as follows:

[0057] S1: Place the mounting frame 11 of this device in the preset installation area next to the concrete column to complete the initial placement. The initial placement can quickly determine the approximate position of the bracket, laying the foundation for subsequent precise adjustment.

[0058] S2: Tighten the connecting screw 37 on one side of the mounting plate 31. The connecting screw 37 generates axial tension through thread transmission, pulling the upper rack 33 to slide within the mounting plate 31. Through gear and rack meshing transmission, the linear motion is converted into the rotational motion of the gear, driving the transmission gear 32 to rotate. The transmission gear 32 synchronously drives the lower rack 34 to slide within the mounting plate 31, realizing the opposite synchronous movement of the upper and lower racks. The spacing of the two L-shaped grippers 2 on the left and right sides of this side is adjusted synchronously to quickly adapt to the current size of the concrete column, allowing the grippers to fit tightly against the column and complete the initial clamping.

[0059] S3: Perform the same adjustment operation as S2 on the symmetrical mounting plate 31 on the other side to make the upper and lower sides of the bracket clamped and fixed. Under the pre-tightening force of the spring 25, the pressing plate 24 of the L-shaped claws 2 on the upper and lower sides of the mounting frame 11 forms a flexible clamp with the column. The flexible clamp can ensure the clamping firmness and will not damage the surface of the column, thus completing the overall fixation of the device on the concrete column and ensuring that the bracket does not shift during subsequent adjustment.

[0060] S4: Tighten the horizontal adjusting screw 13 and the vertical adjusting screw 14. The screws provide precise adjustment thrust through threaded transmission, adjusting the positioning frame 12 to the preset position. The screws rotate, smoothly pushing the positioning frame 12 and changing its spatial position. At this time, the corresponding slider 18 slides along the guide rail 17. The sliding process is smooth and without jamming. The slider 18 connected to the vertical guide post 15 and the horizontal guide post 16 slides synchronously along the corresponding guide rail 17. The vertical guide post 15 and the horizontal guide post 16 slide in cooperation with the mounting frame 11, strictly limiting the movement direction of the positioning frame 12 and avoiding deviation during adjustment.

[0061] S5: Insert the basic embedded part into the positioning frame 12. The cavity structure of the positioning frame 12 can smoothly accommodate the embedded part, providing preliminary positioning constraints for the embedded part.

[0062] S6: Make fine adjustments to the horizontal adjusting screw 13 and the vertical adjusting screw 14 again. Through small-amplitude precise adjustments, the foundation embedded parts in the positioning frame 12 are precisely aligned with the preset positioning positions to meet the high-precision installation requirements of the vertical rolling mill foundation embedded parts.

[0063] S7: Carry out the fixing and installation of basic embedded parts. Complete the installation of embedded parts under the premise of accurate positioning to improve installation efficiency and quality.

[0064] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.

10. A method of using an adjustable positioning bracket for embedded parts in a vertical rolling mill foundation, comprising the adjustable positioning bracket for embedded parts in a vertical rolling mill foundation as described in claim 8, characterized in that, Includes the following steps: S1: Place the mounting frame (11) of this device in the preset installation area next to the concrete column to complete the initial placement; S2: Tighten the connecting screw (37) on one side of the mounting plate (31). The connecting screw (37) pulls the upper rack (33) to slide inside the mounting plate (31). Through the gear and rack meshing transmission, the transmission gear (32) is driven to rotate. The transmission gear (32) synchronously drives the lower rack (34) to slide inside the mounting plate (31). The distance between the two L-shaped claws (2) on the left and right sides of this side is adjusted synchronously to match the current size of the concrete column and clamp the concrete column. S3: Perform the same adjustment operation as S2 on the symmetrical mounting plate (31) on the other side. Under the pre-tightening force of the spring (25), the pressing plate (24) of the L-shaped claw (2) on the upper and lower sides of the mounting frame (11) forms a flexible clamp with the column, thus completing the overall fixation of the device on the concrete column. S4: Tighten the horizontal adjusting screw (13) and the vertical adjusting screw (14) to adjust the positioning frame (12) to the preset position. The screw rotates and pushes the positioning frame (12) to change the spatial position of the positioning frame (12). At this time, the corresponding slider (18) slides along the guide rail (17). The slider (18) connected to the vertical guide post (15) and the horizontal guide post (16) slides synchronously along the corresponding guide rail (17). The vertical guide post (15) and the horizontal guide post (16) slide with the mounting frame (11) to restrict the movement direction of the positioning frame (12). S5: Insert the foundation embedded part into the positioning frame (12); S6: Fine-tune the horizontal adjusting screw (13) and the vertical adjusting screw (14) to make the foundation embedded part in the positioning frame (12) accurately aligned with the preset positioning position; S7: Carry out the work of fixing and installing the foundation embedded parts.
