[0002] A wall-climbing welding robot is an automated device capable of performing welding operations on vertical or inclined surfaces. It is widely used in shipbuilding, petrochemicals, and steel structure construction. These robots typically possess strong adsorption capabilities (such as magnetic adsorption or vacuum adsorption) and flexible mobility, enabling them to complete high-precision welding tasks in complex spaces.

[0003] Existing wall-climbing welding devices typically use magnetic adsorption structures for movement, which is costly. If a track-type movement structure is used, it cannot be well applied to vertical or curved tracks, and further improvements are needed.

[0004] Therefore, it is necessary to invent a wall-climbing welding device. Utility Model Content

[0017] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention. Example 1:

[0018] Please refer to the appendix. Figures 1-3The present invention provides a wall-climbing welding device, including a mounting plate 1, a drive assembly fixed on the mounting plate 1, a track assembly fixed at the bottom of the mounting plate 1, a wall-climbing welding assembly rotatably mounted on the track assembly, and the wall-climbing welding assembly being fixedly connected to the drive assembly. The drive component is a servo motor 2. The bottom of the servo motor 2 is vertically fixed to the top of the mounting plate 1. A winding wheel 3 is fixed to the front end of the output shaft of the servo motor 2. A rope hole 4 is opened on the mounting plate 1. The wall of the rope hole 4 is set to be arc-shaped. A traction rope 5 is wound and fixed on the winding wheel 3. The traction rope 5 passes through the rope hole 4. Specifically, when the servo motor 2 is running, it can drive the winding wheel 3 to rotate in both directions, thereby controlling the winding and unwinding of the traction rope 5. The wall-climbing welding assembly consists of two mobile carts 6. A connecting rope buckle 7 is fixed to the top of the upper mobile cart 6, and the bottom end of the traction rope 5 is fixedly connected to the connecting rope buckle 7. The bottom end of the upper mobile cart 6 is rotatably connected to the top end of the lower mobile cart 6 via a rotating shaft 8. A welding robot 9 is fixed inside the mobile cart 6. It should be noted that the welding robot 9 is a technology known to those skilled in the art, and its specific structure and working principle will not be described in detail. Fixed plates 10 are fixed at the corners on both sides of the mobile cart 6. Limiting holes 11 are opened in the center of each fixed plate 10, and limiting rods 12 penetrate through each limiting hole 11. Each end of the limit rod 12 is fixed with a limit block 13, and the other end of the limit rod 12 is fixed with a connecting frame 14. A spring 15 is fixed to the end of the connecting frame 14. The end of the spring 15 away from the connecting frame 14 is fixed to the surface of the fixing plate 10. The end of the connecting frame 14 away from the spring 15 is rotatably mounted with a traveling wheel 16. Specifically, when the servo motor 2 runs and drives the winding wheel 3 to rotate in the forward and reverse directions, the two moving carts 6 can be controlled to move up and down by winding and releasing the traction rope 5. The two moving carts 6 can rotate between each other. Moreover, under the elastic force of the spring 15, each traveling wheel 16 can be moved and adjusted, so it can be well applied to vertical track walking or arc track walking. The track assembly is a vertical track 17, with the bottom of the mounting plate 1 fixed to the top of the vertical track 17. The vertical track 17 has a vertical track groove 18, and the wheels 16 all roll within the vertical track groove 18 (e.g., ...). Figure 1 As shown in the figure, the two mobile vehicles 6 can move up and down on the vertical track 17 via the walking wheels 16. Therefore, the device can adopt a track-type moving structure to realize the function of climbing welding, which greatly reduces the cost and is well applicable to both vertical and curved tracks, with a wide range of applications.

[0019] It should be noted that the device is electrically connected to an external controller and 220V AC mains power. The controller can be an existing technology device such as a computer. In this utility model, the precise control principle of the servo motor 2 driving the moving vehicle 6 to lift and lower the distance is achieved by the mechanical cooperation between the servo motor 6 and the winding wheel 3 to realize motion conversion. The status is monitored in real time with the help of encoders, limit switches and other devices. Finally, the controller dynamically adjusts the output according to the deviation, thereby achieving precise control of position, speed and force within the millimeter or even micrometer range.

[0020] The usage process of this utility model is as follows: The operator can first lay and install the vertical track 17 on the required welding equipment, then move the mobile vehicle 6 on the vertical track 17 via the walking wheels 16, fix the mounting plate 1 above the vertical track 17, and install the servo motor 2. Then, pull out the traction rope 5 on the winding wheel 3 and pass it through the rope hole 4, so that the bottom end of the traction rope 5 is fixed on the connecting rope buckle 7 on the top of the mobile vehicle 6. When welding is required, the operator starts the servo motor 2 and the welding robot 9 through the controller. When the servo motor 2 runs and drives the winding wheel 3 to rotate, the two mobile vehicles 6 can be raised and lowered by winding and releasing the traction rope 5, so that the mobile vehicle 6 can move along the vertical weld seam, thereby enabling the welding robot 9 to perform welding operations on the vertical weld seam. Example 2:

[0021] Please refer to the appendix. Figure 4 This utility model provides a wall-climbing welding device, wherein the track assembly is an arc-shaped track 19, the bottom of the mounting plate 1 is fixed to the top of the arc-shaped track 19, and an arc-shaped track groove 20 is provided inside the arc-shaped track 19. The traveling wheels 16 all roll into the arc-shaped track groove 20 (e.g., Figure 4 As shown in the figure, the two mobile vehicles 6 can move up and down on the arc track 19 via the walking wheels 16. Therefore, the device can adopt a track-type moving structure to realize the function of climbing welding, which greatly reduces the cost and is well applicable to both vertical and arc tracks, with a wide range of applications.

[0022] The usage process of this utility model is as follows: The operator can first lay and install the arc-shaped track 19 on the required welding equipment, then move the mobile carriage 6 on the arc-shaped track 19 through the walking wheels 16, fix the mounting plate 1 on the arc-shaped track 19, and install the servo motor 2. Then, pull out the traction rope 5 on the winding wheel 3 and pass it through the rope hole 4, so that the bottom end of the traction rope 5 is fixed on the connecting rope buckle 7 on the top of the mobile carriage 6. When welding is required, the operator starts the servo motor 2 and the welding robot 9 through the controller. When the servo motor 2 runs and drives the winding wheel 3 to rotate in both directions, the two mobile carriages 6 can be raised and lowered by winding and releasing the traction rope 5. The two mobile carriages 6 can rotate between each other, and under the elastic force of the spring 15, each walking wheel 16 can be moved and adjusted. Therefore, the mobile carriage 6 can move along the arc-shaped weld seam, so that the welding robot 9 can perform welding operations on the arc-shaped weld seam.

Any person skilled in the art can modify this utility model or modify it into an equivalent technical solution using the technical solution described above.
