[0042] With reference to Figure 1 , Figure 2 and Figure 7 , the scrap blowing mechanism 8 comprises a connecting frame 801 fixedly connected to the outside of the fixed frame 2, providing a mounting position for the ventilation pipe 802, so that the fan 803 is stably fixed. The top of the connecting frame 801 is fixedly connected with the ventilation pipe 802, which serves as the main airflow transmission pipe and provides a stable and smooth conveying channel for the airflow generated by the fan 803. The inside of the ventilation pipe 802 is installed with the fan 803, which is the core power component of the scrap blowing mechanism. It can generate powerful airflow, which is sucked into and accelerated out of the ventilation pipe 802 through high-speed rotating blades, providing the necessary power for rust scrap cleaning. The bottom of the ventilation pipe 802 is fixedly connected with a concentrating cover 804, which can concentrate and guide the relatively dispersed airflow flowing out of the ventilation pipe 802. The bottom of the concentrating cover 804 is fixedly connected with a air supply pipe 805, which is responsible for accurately conveying the airflow treated by the concentrating cover 804 to the positions of the connecting pipe 806 and the nozzle 807. It has certain flexibility and bendability, and can reasonably plan the path and install according to the overall layout of the rust removal assembly and the position requirements of the nozzle 807, so that the airflow can bypass various obstacles to realize long-distance and directional cleaning of rust scrap. The end of the air supply pipe 805 away from the connecting frame 801 is communicated with the connecting pipe 806, which is communicated with the air supply pipe 805 and mainly serves to uniformly distribute the airflow to multiple nozzles 807. The bottom of the connecting pipe 806 is fixedly connected with multiple nozzles 807, and the arrangement of multiple nozzles 807 enables the scrap blowing mechanism to clean rust scrap from multiple directions. The outside of the connecting pipe 806 is fixedly connected to the outside of the laser welder 304, and the fixed connection of the connecting pipe 806 and the laser welder 304 realizes the synchronous operation of scrap blowing and rust removal.
[0043] With reference to Figure 1 , Figure 2 and Figure 8The electrostatic elimination mechanism 9 comprises an electrostatic column 902 capable of leading away or neutralizing electrostatic charges to avoid safety hazards such as spark discharge caused by static electricity. The bottom of the electrostatic column 902 is inserted with a mounting cylinder 901 fixedly connected to the top of the support frame 1, which provides a stable mounting basis for the electrostatic column 902.
[0044] With reference to Figure 1 , Figure 2 and Figure 8 , the mounting cylinder 901 and the inner side of the electrostatic column 902 are provided with a lock hole 903 inserted with a lock rod 904, and the cooperation of the lock hole 903 and the lock rod 904 realizes reliable fixation of the electrostatic column 902 and the mounting cylinder 901. By inserting the lock rod 904 into the lock hole 903, the electrostatic column 902 can be effectively prevented from falling out of the mounting cylinder 901 due to factors such as vibration and airflow impact during work, ensuring the integrity and stability of the structure of the electrostatic elimination mechanism 9.
[0045] Working principle: by rotating the handle 703, the adjusting screw 702 is driven to rotate, and under the guidance of the guide rod 704, the movable plate 701 can only move linearly along the guide rod 704. When the adjusting screw 702 rotates, the movable plate 701 will move with the rotation of the adjusting screw 702, thereby driving a support plate 4 to move, and then driving a limiting mechanism 5 to move, thereby adjusting the distance between the two support plates 4 according to the length of the steel pipe.
[0046] At this time, the two ends of the steel pipe are respectively sleeved on the two limiting mechanisms 4, and then the electric telescopic rod 502 is started. The telescopic end of the electric telescopic rod 502 starts to retract, driving the moving plate 503 to move, and the connecting block 504 on the outer side of the moving plate 503 moves with the moving plate 503. The connecting block 504 drives the connecting rod two 506 to move through the connecting rod one 505. Since the connecting rod one 505 and the connecting rod two 506 are connected through the shaft, and there are multiple groups of connecting rod two 506 on the outer side of the fixed cylinder 501, when the connecting rod one 505 moves, the connecting rod two 506 will change the angle. For the hollow steel pipe, the movement of the fixed shell 507 and the sliding plate 508 inside it can clamp the steel pipe from both the inside and outside of the steel pipe. The connecting plate 509 on the side of the fixed shell 507 away from the fixed cylinder 501 and the rubber pad 5010 are in contact with the steel pipe. The rubber pad 5010 can increase the friction force to prevent the steel pipe from rotating during rust removal, ensuring the stability of the steel pipe during rust removal. At the same time, it can adapt to steel pipes of different diameters, and by adjusting the telescopic degree of the electric telescopic rod 502, the effective fixation of steel pipes of different diameters can be realized.
[0047] When the hollow steel pipe is fixed, the electric guide rail 301 is started, the electric sliding block 302 on the outside of the electric guide rail 301 can move along the electric guide rail 301, and the laser welder 304 at the bottom of the connecting seat 303 is moved to the position outside the hollow steel pipe to be derusted. The laser welder 304 emits a high-energy-density laser beam, and the laser beam irradiates the rust on the outer surface of the hollow steel pipe. After the rust absorbs the laser energy, it is rapidly heated and instantaneously gasified or peeled off from the surface of the steel pipe in the form of tiny particles, thereby realizing the derusting operation outside the hollow steel pipe.
[0048] By starting the motor 6, one of the fixed cylinders 501 is driven to rotate, and the hollow steel pipe on the limiting mechanism 5 is driven to rotate, so that the hollow steel pipe can realize all-around derusting during the derusting process. When the position of the laser derusting device is relatively fixed, the rotation of the steel pipe can make the rust on the outer surface at different angles be irradiated by the laser, avoiding the dead angle of derusting due to the fixed position of the steel pipe, and ensuring more thorough derusting.
[0049] When the laser welder 304 is started, the fan 803 is also started, and the fan 803 generates an air flow in the ventilation duct 802. The air flow is concentrated and guided through the concentrating cover 804, and then is sprayed from the spray head 807 through the air supply pipe 805 and the connecting pipe 806. The spray head 807 is connected to the outside of the laser welder 304, and can move with the laser welder 304. During the laser derusting process, the rust generated is blown away from the surface of the hollow steel pipe in time, preventing the rust from accumulating on the steel pipe to affect the derusting effect or re-attaching to the derusted steel pipe surface.
[0050] The electrostatic column 902 is fixed on the top of the support frame 1 through the mounting cylinder 901, and the mounting cylinder 901 and the electrostatic column 902 are fixed through the lock hole 903 and the lock rod 904. During the laser derusting process, the hollow steel pipe may generate static electricity due to the laser effect, friction with the limiting mechanism and other components. The electrostatic column 902 can guide or neutralize the static charge, avoid problems such as spark discharge and adsorption of rust caused by static electricity, and ensure the safe and effective performance of the derusting work.
[0051] Finally, it should be noted that the above description is only a preferred embodiment of the present application and is not intended to limit the present application. Although the present application 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 equivalently replace some technical features, as long as they are within the spirit and principles of the present application. Any modification, equivalent replacement, improvement, etc. made within the scope of the present application shall be included in the protection scope of the present application.
