[0029] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0032] Example, refer to Figures 1 to 4 This embodiment provides a roller welding aid for welding guide wheels of a ship lift, including a base 1. The top of the base 1 is provided with a telescopically adjustable lifting component 2. The telescopic end of the lifting component 2 is connected to a guide wheel bearing mechanism 3. The guide wheel bearing mechanism 3 is provided with a through-fitting component for fitting guide wheels with different inner diameters to ensure the stability of the guide wheel during the welding process.

[0033] The mounting assembly includes a rotating plate 35, a second servo motor 37, a contact rod 38, a hinge rod 311, a threaded sleeve 315, and a guide wheel support plate 317. The second servo motor 37 is installed at the center of one side of the rotating plate 35. Several sets of connecting rods 36 arranged in a ring array are installed on the side of the rotating plate 35. The guide wheel support plate 317 is fixedly connected to one side of the connecting rods 36. Several sets of guide through holes extending radially towards the center are provided on the guide wheel support plate 317, and a contact rod 38 for engaging and locking from the inside of the guide wheel is inserted through the guide through holes.

[0034] A through hole is provided at the center of the guide wheel bearing plate 317, and a threaded sleeve 315 is slidably provided at the through hole. The servo motor 37 is threadedly engaged with the threaded sleeve 315. A fixed circular plate 314 is fixedly connected to the end of the threaded sleeve 315. Several sets of hinge rods 311 that are hinged to the abutment rod 38 are evenly arrayed and rotatably connected to the side of the fixed circular plate 314.

[0035] The output shaft of the servo motor 37 is coaxially connected to an adjusting screw 312. One end of the adjusting screw 312 is threaded into the inner side of the threaded sleeve 315. The outer side of the threaded sleeve 315 is provided with several sets of guide ridges, and the through hole on the guide wheel bearing plate 317 is provided with a notch that matches the guide ridges. This facilitates the torque to drive the threaded sleeve 315 and the fixed circular plate 314 to move stably, thereby achieving the deflection of the hinge rod 311 and driving the abutment rod 38 to open and close. This allows the device to stably abut guide wheels with different inner diameters.

[0036] Furthermore, the guide wheel bearing mechanism 3 also includes a connecting cover 31 fixedly connected to the lifting assembly 2. A fixed base plate 32 is fixedly connected to one side of the connecting cover 31. A servo motor 33 is fixedly installed at the center of the side of the fixed base plate 32. The output shaft of the servo motor 33 is coaxially connected to the rotating plate 35, thereby stably driving the through assembly to rotate and ensuring the angle adjustment of the guide wheel during the welding process.

[0037] Specifically, a number of sets of fixing posts 316 are fixedly connected to the side of the fixing base plate 32, and a bearing ring 34 is fixedly connected to one end of the fixing post 316. The bearing ring 34 has an annular groove on its inner side.

[0038] A limiting ring 313 that matches the annular groove on the bearing ring 34 is installed on the outer side of the rotating plate 35, thereby ensuring that the entire threading component is stably supported during the rotation of the threading component driven by the servo motor 33, and ensuring actual stability.

[0039] Furthermore, the guide wheel bearing mechanism 3 also includes a clamping plate 39, which has a strip-shaped through hole corresponding to that on the guide wheel bearing plate 317 for the abutment rod 38 to pass through.

[0040] Furthermore, the end of the abutment rod 38 that passes through the strip-shaped through hole on the pressure plate 39 is threaded with a locking nut 310 to lock the position of the pressure plate 39, preventing the guide wheel from slipping during the installation process and further ensuring stability.

[0041] Furthermore, the lifting assembly 2 includes a fixed sleeve 21 fixedly connected to the top of the base 1. The top of the fixed sleeve 21 is open, and an L-shaped lifting rod 25 is inserted into the opening. The horizontal end of the L-shaped lifting rod 25 is fixedly connected to the guide wheel bearing mechanism 3. A rack is provided on one side of the vertical section of the L-shaped lifting rod 25.

[0042] A mounting bracket 22 is provided on one side of the top end of the fixed sleeve 21, and a lifting motor 23 is installed on the side of the mounting bracket 22. The output shaft of the lifting motor 23 is coaxially connected to a meshing gear 24, and the top side of the fixed sleeve 21 is provided with an opening for the meshing gear 24 to enter. The meshing gear 24 meshes with the rack on the L-shaped lifting rod 25 at the opening, thereby effectively driving the L-shaped lifting rod 25 to rise and fall, realizing the lifting and adjustment of the guide wheel driven by the overall guide wheel bearing mechanism 3.

[0043] Furthermore, several sets of guide wheels are evenly installed at the bottom of the base 1 to stably realize the effective movement of the entire device.

[0044] In use, the guide wheel, which has undergone welding treatment, is first sleeved on the outside of the abutment rod 38. Then, the servo motor 37 is started, which drives the adjusting screw 312 to rotate. Under the torque action between the adjusting screw 312 and the threaded sleeve 315, and with the setting of the guide ridge on the outside of the threaded sleeve 315, the fixed circular plate 314 moves accordingly, causing the hinge rod 311 to deflect, which in turn drives the abutment rod 38 to move. This allows the abutment rod 38 to stably adapt to guide wheels with different inner diameters and to stably abut against the inside of the guide wheel.

[0045] After the contact is completed, the guide wheel is locked by fitting the clamping plate 39 and rotating the locking nut 310 to prevent the guide wheel from slipping during the welding process;

[0046] In subsequent use, by starting the lifting motor 23 on the lifting assembly 2, the meshing gear 24 drives the L-shaped lifting rod 25 to rise and fall, thereby enabling the guide wheel bearing mechanism 3 to drive the guide wheel to adjust its height, which helps the subsequent welding operation.

[0047] During the subsequent welding process, the servo motor 33 can be activated to enable stable angle adjustment of the entire assembly, facilitating the adjustment of the guide wheel angle during actual use.

[0048] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
