Description

Technical Field

[0001] The utility model relates to the field of thermoplastic line marking and pay-out robots, in particular to an automatic pay-out robot for thermoplastic line marking operations. Background Art

[0002] The thermoplastic road marking robot is an advanced automated device used in road marking construction. It cleverly integrates the melting, mixing, and precise application of thermoplastic coatings to achieve efficient, uniform, and accurate road marking. The robot incorporates cutting-edge navigation systems such as GPS or laser guidance to ensure that both straight and curved markings meet precise design requirements.

[0003] However, in practice, thermoplastic road marking robots also face certain safety risks, particularly the potential for entanglement of the robot arm caused by the placement line. If the placement line is improperly set, the robot arm may overlap or intersect with the placement line during operation, causing entanglement. This entanglement not only disrupts the robot's normal operation but also poses a safety threat to the operator, increasing the risk factor on the job site.

[0004] Therefore, in order to ensure the safety and smoothness of the operation of the thermoplastic marking robot, it is necessary to attach great importance to the layout planning of the placement line to ensure that it maintains a safe distance from the movement trajectory of the robot to avoid any possible conflict and entanglement risks. Utility Model Content

[0005] The main purpose of the utility model is to provide an automatic line-laying robot for thermoplastic line marking operations, which can effectively solve the problems raised in the background technology.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0026] like Figure 1 - Figure 5 As shown, an automatic line-laying robot for thermoplastic marking mainly includes a base 1, a support frame 2, a winding drum 3, a drive motor 4, a mounting base 5, a manipulator 6, an angle adjuster 7, a line-laying device 8, a connecting disc 9, a base tube 10, a first telescopic tube 11, a second telescopic tube 12, a fixing base 13, a connecting base 14, a guide roller 15, a clamping roller 16, a hydraulic cylinder 18 and a bearing device 17 and other core components.

[0027] Base 1 serves as the stable foundation of the entire machine, with multiple functional modules meticulously arranged on its upper end. A mounting base 5 is fixed to one side, upon which a flexible robotic arm 6 is mounted. This arm is tightly connected to a wire payout 8 via a precise angle adjuster 7. This ingenious design allows the payout 8 to flexibly adjust its angle and position, ensuring accurate and efficient payout.

[0028] On the other side of base 1 stands a sturdy support frame 2. Its unique "U" shape is not only aesthetically pleasing but also facilitates installation and maintenance. Inside, a winding drum 3 is meticulously positioned and controlled by a powerful drive motor 4, allowing for effortless payout and reeling operations.

[0029] To further enhance the device's flexibility and adaptability, a connecting disc 9 is mounted in the center of the base 1. A base tube 10 is positioned vertically above this disc, nested within which are a first telescopic tube 11 and a second telescopic tube 12. This nested design is not only compact but also securely fastened via threaded connections and latch holes, ensuring precise height adjustment and stability. The upper end of the second telescopic tube 12 is tightly connected to a fixing base 13, forming a stable support structure.

[0030] Two opposing connecting blocks 14 are mounted above the fixed base 13. Between them, a guide roller 15 and a clamping roller 16 are strategically placed. Both feature curved surfaces and are covered with a soft rubber sleeve to minimize wear and friction on the placement wire. Each connecting block 14 is equipped with a hydraulic cylinder 18 at its top. Its telescopic movement precisely adjusts the position of the clamping roller 16, ensuring secure grip and guidance of the placement wire. The guide rollers 15 guide the placement wire along the predetermined path, ensuring smooth and accurate payout.

[0031] In addition, bearings 17 are installed at the rotating shafts of the guide roller 15 and the clamping roller 16 to ensure flexible and smooth rotation. The bearing 17 of the guide roller 15 is bolted to the connecting base 14, while the bearing 17 of the clamping roller 16 is cleverly fixed to the telescopic end of the hydraulic cylinder 18, achieving close coordination and cooperation between the two.

[0032] The entire machine is arranged from left to right: support frame 2, connecting disc 9, and mounting base 5. These three components are closely connected, yet each performs its own function, forming this highly efficient, intelligent automatic pay-out robot for thermoplastic road marking operations. Its innovative design and superior performance are poised to revolutionize and enhance thermoplastic road marking operations.

[0033] Usage process: Place the automatic line-laying robot for thermoplastic marking operations at the predetermined operating position and ensure that the base 1 is stable. Start the drive motor 4, and the winding drum 3 in the support frame 2 begins to rotate to perform the line-laying operation. Use the manipulator 6 on the mounting base 5 to operate the line-laying device 8 and adjust the angle and position according to the operating requirements. Use the connecting disc 9 and the base pipe 10 to adjust the length of the first telescopic tube 11 and the second telescopic tube 12 to adapt to different working environments. Ensure that the fixed base 13 is stable, and the guide roller 15 and the clamping roller 16 on the connecting base 14 work together to guide the placement line along the predetermined path. The hydraulic cylinder 18 telescopically moves to accurately adjust the position of the clamping roller 16 to firmly clamp and guide the placement line.

[0034] During adjustment: If the pay-off angle needs to be adjusted, operate the angle adjuster 7 on the manipulator 6 to fine-tune the position and angle of the pay-off 8. If the pay-off length needs to be changed, adjust the telescopic amount of the first telescopic tube 11 and the second telescopic tube 12, and fix them through threaded connections and pin holes to ensure precise adjustment. If the line placement path needs to be fine-tuned, operate the guide roller 15 and the clamping roller 16, and adjust their position through the telescopic movement of the hydraulic cylinder 18. Check and ensure that all bearing devices 17 are operating flexibly. If they are found to be rotating poorly, perform necessary lubrication or replacement. Regularly check the stability of components such as the connecting disc 9, base pipe 10, fixing seat 13, and connecting seat 14 to ensure that the overall structure is stable and reliable.

[0035] The standard parts used in this utility model can all be purchased from the market, and special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the existing technology. The machinery, parts and equipment all adopt conventional models in the existing technology, and the electric fusion connection adopts the conventional connection method in the existing technology, which will not be described in detail here.

[0036] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to them. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
