[0033] Pipe material a. Detailed Implementation

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0035] Reference Figure 1-7 An automated laser rust removal tooling includes a material rack mechanism 1 for placing pipes, a rust removal mechanism 2 for removing rust from the pipes, and a lifting mechanism 3 for adjusting the height of the rust removal mechanism 2.

[0036] The material rack mechanism 1 includes a workbench 11, multiple roller frames 15 evenly arranged on the workbench 11, two rollers 16 symmetrically rotated on the roller frames 15, and a drive assembly 17 for driving the rollers 16 to rotate. When removing rust from the pipe, the pipe is placed on the two roller frames 15, and the pipe is supported by the two rollers 16 on the roller frames 15. The drive assembly 17 drives one of the rollers 16 to rotate, thereby driving the pipe to rotate, so that the rust removal mechanism 2 can uniformly remove rust from the outer wall of the pipe.

[0037] The rust removal mechanism 2 includes a support plate 21 parallel to one side of the workbench 11, a self-propelled trolley 23 movable in a straight line on the support plate 21, a rust removal gun head 241 fixedly mounted on the self-propelled trolley 23 via a bracket, and the rust removal gun head 241 connected to the rust removal machine 24 via a cable. The rust removal machine 24 is a laser rust removal machine, with an optical fiber in the cable for transmitting laser light. During rust removal, the self-propelled trolley 23 moves at a specific speed, working in conjunction with the rust removal gun head 241 to remove rust from the pipe surface. The self-propelled trolley 23 can be a semi-automatic pipe cutting machine. The moving speed of the self-propelled trolley 23 is matched with the pipe diameter and the pipe's rotation speed, calculated as follows:

[0038] Self-propelled trolley speed = pipe rotation speed × laser effective width (distance traveled per revolution).

[0039] Based on the above technical solution, when removing rust from pipes, the pipe is placed on roller 16, and the height of the rust removal gun head 241 is adjusted by adjusting the lifting mechanism 3 until the laser spot is distributed along the pipe axis. Rust removal begins when the drive assembly 17 drives the roller 16 to rotate, causing the pipe to rotate at a certain speed. The laser rust removal machine is then started, and the laser emitted by the rust removal gun head 241 removes rust from the pipe surface. As the pipe rotates, the surface is completely rust-removed, ensuring good uniformity and efficiency in rust removal.

[0040] In this technical solution, such as Figure 1-6 As shown, the worktable 11 has two symmetrically arranged slide rods 12 parallel to the axis of the rollers 16. Multiple sliders 14 are slidably mounted on the slide rods 12, and slide plates 13 are fixedly installed on the sliders 14. The roller frame 15 is fixedly installed on the slide plates 13. The cooperation between the slide rods 12 and the sliders 14 ensures the linear sliding of the roller frame 15, allowing adjustment of the distance between the two roller frames 15. This facilitates adjustment according to different pipe lengths and ensures good compatibility with different pipes.

[0041] In this technical solution, such as Figure 1-4As shown, the drive assembly 17 includes a motor 173 located below the slide plate 13, a synchronous pulley 171 fitted on the output shaft of the motor 173 and the rotating shaft of one of the rollers 16, and a synchronous belt 172 fitted on the outer side of the synchronous pulley 171. The motor 173, in conjunction with the synchronous pulley 171 and the synchronous belt 172, drives the roller 16 to rotate. The motor 173 can be a servo motor, a roller motor, etc. This ensures that the rotation speed of the pipe is uniform and controllable, guaranteeing the rust removal effect and avoiding situations where the rust removal is incomplete due to excessive speed or inefficient due to excessively slow speed.

[0042] In this technical solution, such as Figure 1-3 As shown, an clearance opening is provided between the two sliding rods 12 on the workbench 11, and a collection hopper 18 is provided below the workbench 11 corresponding to the clearance opening. This facilitates the collection of rust chips and other debris that fall during rust removal, ensuring a clean working environment.

[0043] In this technical solution, such as Figure 1-6 As shown, a track 22 is provided on the support plate 21 along the moving direction of the self-propelled trolley 23. A guide bar 221 is correspondingly provided on the track 22. A wheel 231 is provided at the lower end of the self-propelled trolley 23 corresponding to the track 22. A guide groove 2311 is opened on the annular side wall of the wheel 231 corresponding to the guide bar 221. Through the design of the guide bar 221 and the guide groove 2311, the stable straight movement of the self-propelled trolley 23 is ensured, the distance between the rust removal gun head 241 and the pipe is appropriate, and the uniformity of rust removal is ensured.

[0044] In this technical solution, such as Figure 1-5 As shown, end plates are provided on the upper sides of both sides of the track 22, and the distance between the end plates is set according to the length of the pipe. Limit switches 232 are provided on the inner side of the end plates corresponding to the self-propelled trolley 23 to control the on / off state of the rust removal gun head 241. When the self-propelled trolley 23 is removing rust, the limit switch 232 is triggered when the rust removal reaches the end of the pipe, turning off the rust removal gun head 241, saving energy and improving the safety of the equipment during use.

[0045] In this technical solution, such as Figure 1-5 As shown, a cable chain 25 is provided on the side of the support plate 21 away from the workbench 11 corresponding to the cable. This ensures the smooth movement of the cable 25 when the self-propelled trolley 23 moves, and the cable chain 25 also protects the optical fiber in the cable 25, thus protecting the optical transmission system.

[0046] In this technical solution, such as Figure 1-6As shown, a spray gun head 26 is fixedly mounted on the self-propelled trolley 23 via a bracket. The spray gun head 26 is connected to an air supply device via a hose. The air supply device can be equipped with an air compressor and a dry cooler. Air is sprayed through the spray gun head 26 to clean the pipes after rust removal, preventing residual rust from adhering and further improving the rust removal effect. The spray gun head 26 can be equipped with a valve and electrically connected to a limit switch 232 to save energy and reduce safety hazards.

[0047] In this technical solution, such as Figure 1-7 As shown, the lifting mechanism 3 includes multiple screw jacks 31 disposed below the support plate 21 and a mounting bracket 313 for supporting the screw jacks 31. The upper end of the screw 311 of each screw jack 31 is fixedly connected to the support plate 21. The worm gears 312 of each screw jack 31 are connected to each other via a coupling 32, and one of the worm gears 312 is connected to a handwheel 33. The design of the coupling 32 creates an extended manual multi-screw jack, improving the stability of the lifting mechanism 31 in raising and lowering the support plate 21. The handwheel 33 can also be replaced with a servo motor to achieve automated lifting of the rust removal mechanism 2.

[0048] In this technical solution, such as Figure 1-7 As shown, multiple stabilizing rods 34 are vertically fixedly installed on both sides of the support plate 21. Sliding sleeves 35 are slidably connected to the outer side of the stabilizing rods 34, and the sliding sleeves 35 are fixedly installed by the fixing bracket 351. Through the design of the stabilizing rods 34 and the sliding sleeves 35, the vertical lifting and lowering of the support plate 21 is limited, further improving the stability of the lifting and lowering of the support plate 21, ensuring the horizontality of the support plate 21, and thus ensuring the uniform speed movement of the self-propelled trolley 23.

[0049] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
