The terms "first", "second", etc. in the specification and claims of the present application or the above-mentioned figures are used to distinguish different objects, rather than to describe a specific order; the terms "inside", "outside", "left", and "right" indicate directions or positional relationships based on the directions or positional relationships shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0036] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0037] The embodiment of the present invention provides a laser rust removal device for steel component surface, such as Figure 1-16 As shown, the laser rust removal equipment for the surface of steel components comprises: a neck tube 1, a front end cover 2 and a rear end cover 3, wherein the middle part of the neck tube 1 is a thinner neck, and the two ends are mouths that expand outward to form a receiving concave of the neck, and the front end cover 2 and the rear end cover 3 are respectively fixedly mounted on the two mouths of the neck tube 1; a rotating ring 4 is rotatably mounted on the neck of the neck tube 1; a distribution box 5 is fixedly mounted on the outer ring of the rotating ring 4, and the height of the distribution box 5 is lower than the two mouths of the neck tube 1, and is received in the receiving concave of the neck of the neck tube 1; a support frame 6 is fixedly mounted on one side of the distribution box 5 and is located in the receiving concave of the neck of the neck tube 1; a laser rust removal gun 7 is fixedly mounted on the support frame 6 and is located in the receiving concave of the neck of the neck tube 1, and is used for rotating laser rust removal on the inside of steel structure pipe fittings, and the laser rust removal gun 7 is connected to the distribution box 5; a rotation drive mechanism is arranged at the neck of the neck tube 1, and is used to drive the rotating ring 4 to rotate.

[0038] In the present embodiment, when the laser rust removal equipment for the surface of steel components of the present scheme is used, first, the front end cover 2 of the equipment is aligned with the steel structure pipe fitting or the entrance of the hole to be rusted, ensuring that the laser rust removal gun 7 and the whole can smoothly enter the pipe fitting or the hole. Subsequently, the rotary drive mechanism is started, which drives the rotating ring 4 to rotate at the neck of the neck tube 1. Since the rotating ring 4 is fixedly connected to the distribution box 15 and the support frame 6, the laser rust removal gun 7 also rotates therewith to achieve all-round scanning and rust removal of the inner wall of the pipe fitting. During the rust removal process, the laser rust removal gun 7 emits a high-energy laser beam, which directly irradiates the rust and oil stains on the inner wall of the pipe fitting, causing it to vaporize rapidly, thereby achieving the purpose of cleaning the surface. At the same time, the distribution box 15 provides stable power support for the laser rust removal gun 7 to ensure the continuity and efficiency of the rust removal operation.

[0039] This solution adopts the structural design of the neck tube 1, the front cover 2, the rear cover 3 and the rotatable rotating ring 4, so that the equipment can easily adapt to steel structure pipes of different lengths and diameters. In particular, the neck storage concave design of the neck tube 1 provides sufficient installation space and protection for components such as the laser rust removal gun 7 and the distribution box 5, while not affecting the overall flexibility and ease of operation of the equipment. This design makes the equipment more adaptable and flexible when dealing with rust removal inside deep or long pipes.

[0040] The laser rust removal gun 7 is fixedly mounted on the support frame 6 and rotates with the rotation of the rotating ring 4, realizing all-round and no-dead-angle rust removal on the inner wall of the pipe. The high energy density and rapid gasification characteristics of the laser beam make the rust removal process rapid and thorough, greatly improving the rust removal efficiency. At the same time, the distribution box 15 provides stable power support for the laser rust removal gun 7, ensuring the continuity and stability of the rust removal operation. This efficient rust removal method not only saves time and labor costs, but also improves the use efficiency and economic benefits of the equipment.

[0041] The overall structure of this solution is well designed and easy to operate. The user only needs to align the device with the pipe inlet and start the rotary drive mechanism to start the rust removal operation.

[0042] In a further preferred embodiment of the present invention, the rotary drive mechanism includes a power part avoidance gap 8 opened at the neck position of the neck tube 1, an inner gear ring 9 is fixedly installed on the inner side of the rotating ring 4, a support shaft 10 is rotatably installed in the power part avoidance gap 8, a driving gear 11 is fixedly sleeved on the support shaft 10, the driving gear 11 is meshed with the inner gear ring 9, and is used to drive the rotating ring 4 to rotate, a rotating motor 12 is fixedly installed in the neck tube 1, an output power shaft 13 is fixedly installed on the output shaft of the rotating motor 12, a pulley 14 is fixedly sleeved on the output power shaft 13 and the support shaft 10, and the two pulleys 14 are sleeved with the same synchronous belt 15.

[0043] In this embodiment, by opening the rotating motor 12 fixedly installed in the neck tube 1, the output shaft of the rotating motor 12 drives the output power shaft 13 to rotate. Since the output power shaft 13 and the supporting rotating shaft 10 are both fixedly sleeved with a pulley 14 and connected by a synchronous belt 15, the rotational power of the rotating motor 12 is transmitted to the supporting rotating shaft 10. The driving gear 11 fixedly sleeved on the supporting rotating shaft 10 is meshed with the inner gear ring 9 on the inner side of the rotating ring 4. As the supporting rotating shaft 10 rotates, the driving gear 11 drives the inner gear ring 9 and the entire rotating ring 4 to rotate synchronously. In this way, the laser rust removal gun 7 fixed on the rotating ring 4 also rotates accordingly, realizing all-round laser rust removal of the inside of the steel structure pipe fittings.

[0044] By using a pulley and a synchronous belt to transmit the rotational power, the rotary drive mechanism of the present invention realizes the smooth transmission of power. The synchronous belt 15 has good flexibility and wear resistance, can maintain a stable transmission ratio during high-speed rotation, and reduce power loss and vibration. This design makes the rotation of the rotating ring 4 more stable and reliable, thereby improving the rust removal accuracy and efficiency of the laser rust removal gun 7.

[0045] The rotary drive mechanism of the present invention has a compact structure design, and integrates the power transmission and rotary drive functions at the neck position of the neck tube 1, which effectively saves the equipment space. At the same time, the design of the power part avoiding the gap 8 facilitates the installation of the rotating ring 4 and the driving gear 11, making the assembly and maintenance of the entire mechanism simpler and faster. In addition, due to the tight connection between the various components and the reasonable structure, the overall stability and durability of the equipment are also improved.

[0046] By adjusting the rotation speed and rotation direction of the rotating motor 12, the rotation speed and direction of the rotating ring 4 and the laser rust removal gun 7 can be conveniently controlled. This flexibility enables the device to be suitable for rust removal operations inside steel structure pipes of different sizes, shapes and lengths. At the same time, since the rotating drive mechanism and the laser rust removal gun 7 and other components are independent of each other and do not interfere with each other, the device can maintain high stability and reliability during the rust removal process, and can achieve excellent rust removal effects even in complex working environments.

[0047] In a further preferred embodiment of the present invention, at least one annular track 16 is fixedly sleeved on the neck of the neck tube 1 , and a stabilizing guide ring 17 is rotatably sleeved on the annular track 16 , and the stabilizing guide ring 17 is fixedly connected to the inner wall of the rotating ring 4 .

[0048] In this embodiment, in order to enhance the stability of the rotating ring 4 during the rotation process, at least one annular track 16 is fixedly sleeved on the neck of the neck tube 1. The stabilizing guide ring 17 is rotatably sleeved on the annular track 16 and is fixedly connected to the inner wall of the rotating ring 4. When the rotating motor 12 drives the rotating ring 4 to rotate, the stabilizing guide ring 17 slides smoothly along the annular track 16, providing additional support and guidance for the rotating ring 4, ensuring the stability and accuracy of the rotation. This design enables the laser rust removal gun 7 to maintain a stable trajectory during the rotation rust removal process, thereby improving the uniformity and quality of rust removal.

[0049] By adding the combined structure of the annular track 16 and the stabilizing guide ring 17, the rotating ring 4 of the present invention is effectively supported and stabilized during the rotation process. The annular track 16 provides a clear motion trajectory for the stabilizing guide ring 17, preventing the rotating ring 4 from deflecting or shaking when rotating at high speed. This improvement in stability not only helps to improve the accuracy and efficiency of laser rust removal, but also extends the service life of the equipment and reduces the failure rate caused by vibration and wear.

[0050] Since the rotation stability of the rotating ring 4 is enhanced, the laser rust removal gun 7 fixed thereon can maintain a more uniform trajectory during the rotation rust removal process. This means that the laser beam can be irradiated more evenly to various parts of the inner wall of the steel structure pipe, thereby achieving a more thorough rust removal effect. In addition, the uniform rotation trajectory also helps to reduce the surface unevenness caused by local excessive or insufficient rust removal, and improves the surface quality after rust removal.

[0051] This improvement of the present invention effectively improves the rotation stability of the rotating ring 4 through the simple design of the annular track 16 and the stabilizing guide ring 17 while maintaining the compactness of the original structure. This design not only simplifies the overall structure of the device, reduces the manufacturing cost and maintenance difficulty, but also improves the overall performance and reliability of the device. At the same time, due to the closer and more coordinated cooperation between the various components, the operating noise and vibration of the device are also effectively controlled, providing users with a more comfortable and stable use experience.

[0052] In a further preferred embodiment of the present invention, an air cylinder 18 is rotatably mounted on the output power shaft 13, and the air cylinder 18 is fixedly connected to the inner wall of the neck tube 1, and a blade 19 is fixedly installed on the portion of the output power shaft 13 located in the air cylinder 18, and an air inlet hole 20 and an exhaust hole are opened on the air cylinder 18, and an exhaust pipe 21 is fixedly installed on the air cylinder 18 at the position of the exhaust hole, and the exhaust end of the exhaust pipe 21 extends to the outside of the neck of the neck tube 1 and avoids the rotation trajectory of the rotating ring 4 for internal heat dissipation.

[0053] In the present embodiment, the air cylinder 18 serves as an auxiliary device for internal heat dissipation. The air cylinder 18 is fixedly mounted on the output power shaft 13 and is tightly connected to the inner wall of the neck tube 1. As the output power shaft 13 rotates, the blades 19 fixed thereon rotate in the air cylinder 18 to generate airflow. External air enters the air cylinder 18 through the air inlet 20, is accelerated by the blades 19, and is discharged to the outside of the neck of the neck tube 1 through the exhaust hole and the fixed exhaust pipe 21. In this process, the airflow takes away the heat generated inside the device, achieving effective heat dissipation. At the same time, the exhaust end of the exhaust pipe 21 is specially designed to avoid interfering with the rotation trajectory of the rotating ring 4, thereby ensuring the normal operation of the device.

[0054] By adding an air cylinder 18 and its matching blades 19, air inlet 20, exhaust hole and exhaust pipe 21 to the output power shaft 13, the present invention effectively improves the heat dissipation efficiency of the equipment. This active heat dissipation method can quickly discharge the heat generated by the operation of the equipment, reduce the temperature of the equipment, and prevent overheating from affecting the performance of the equipment. Especially in the process of laser rust removal, components such as laser guns and motors will generate a lot of heat. This heat dissipation design is of great significance for ensuring the long-term stable operation of the equipment.

[0055] Good heat dissipation performance helps to extend the service life of the equipment. Too high temperature will accelerate the aging and damage of the internal components of the equipment, reducing the overall performance and reliability of the equipment. The present invention effectively reduces the temperature of the equipment during operation by introducing heat dissipation structures such as the air cylinder 18, reduces the risk of component damage caused by high temperature, and thus enhances the durability and reliability of the equipment.

[0056] Improving heat dissipation performance not only helps to extend the life of the equipment, but also ensures the stable operation of the equipment under harsh working conditions. In harsh environments such as high temperature and high humidity, the equipment is prone to performance degradation or even failure due to overheating. The present invention optimizes the heat dissipation design to enable the equipment to maintain a stable operating state under various working conditions, ensuring the continuity and efficiency of laser rust removal operations. At the same time, this design also reduces the equipment failure rate and maintenance costs, providing users with a more reliable and economical solution.

[0057] In a further preferred embodiment of the present invention, a second distribution box 22 is fixedly installed inside the rear end cover 3 , and an operating handle 23 is fixedly installed outside the rear end cover 3 .

[0058] In this embodiment, a second power distribution box 22 is fixedly installed inside the rear end cover 3, and an operating handle 23 is added to the outside of the rear end cover 3. When in use, the user can easily move and position the device through the operating handle 23 to align it with the steel structure pipe to be derusted. At the same time, the second power distribution box 22 provides additional power distribution and control functions for the device to ensure that various components can operate in a coordinated manner.

[0059] In a further preferred embodiment of the present invention, the front end cover 2 and the rear end cover 3 are both provided with a walking mechanism, and the walking mechanism includes a contraction opening 24 opened on both sides corresponding to the front end cover 2 and the rear end cover 3, and four support seats 25 are fixedly installed in the front end cover 2 and the rear end cover 3, and the eight support seats 25 are respectively arranged corresponding to the four contraction openings 24, and the eight support seats 25 are each provided with a rectangular guide opening 26, and the eight rectangular guide openings 26 are respectively slidably installed with rectangular slide bars 27 in pairs, and the four rectangular slide bars 27 are respectively arranged corresponding to the four contraction openings 24, and the four rectangular slide bars 27 are respectively arranged corresponding to the four contraction openings 24. A base plate 28 is fixedly installed on one side of the four rectangular slide bars 27 corresponding to the four contraction openings 24, and a wheel axle plate 29 is fixedly installed on one side of the four base plates 28 corresponding to the four contraction openings 24, and a walking wheel 30 is rotatably installed on the four wheel axle plates 29, and the four wheel axle plates 29 and the walking wheel 30 can respectively slide out along the corresponding contraction openings 24 for support inside the steel structure pipe fitting.

[0060] In this embodiment, the front cover 2 and the rear cover 3 of the equipment are additionally provided with a walking mechanism to enhance the mobility of the equipment inside the steel structure pipe. Specifically, by opening a contraction opening 24 on both sides of the front cover 2 and the rear cover 3, and fixing a support seat 25 and a rectangular slide bar 27 inside, a retractable installation of the walking wheel 30 is achieved. When the equipment needs to be pushed into or moved out of the steel structure pipe, the rectangular slide bar 27 slides along the rectangular guide opening 26, so that the wheel axle plate 29 and the walking wheel 30 slide out along the contraction opening 24 until the walking wheel 30 contacts the inner wall of the steel structure pipe. At this time, the walking wheel 30 rolls inside the pipe to achieve convenient movement of the equipment.

[0061] The introduction of the walking mechanism makes the movement of the equipment inside the steel structure pipe more flexible and convenient. Users can easily push the equipment to move inside the pipe without relying on external equipment or manpower, which improves work efficiency and operation flexibility. At the same time, the design of the walking wheel 30 reduces the friction between the equipment and the inner wall of the pipe, reduces wear and noise, and extends the service life of the equipment.

[0062] By adjusting the extension length of the running wheel 30, the user can adapt to steel structure pipes of different diameters and shapes. This retractable running mechanism design enables the equipment to be applicable to internal rust removal operations of pipes of various specifications and types, thereby enhancing the adaptability and versatility of the equipment.

[0063] In a further preferred embodiment of the present invention, the walking mechanism also includes an axial rod member 31 rotatably mounted on the front end cover 2 and the rear end cover 3, and a threaded rod 32 is fixedly mounted on one end of the two axial rod members 31 close to each other, and a sliding block 33 is threadedly sleeved on the two threaded rods 32, and four support seats 2 34 are fixedly mounted on the inner walls of both sides of the neck tube 1, and the eight support seats 2 34 are respectively arranged corresponding to the two sliding blocks 33, and the eight support seats 2 34 are respectively provided with a rectangular guide opening 2 35, and the eight rectangular guide openings 2 35 are respectively slidably mounted with rectangular slide bars 2 36 in pairs, and the four rectangular slide bars 2 36 are respectively hinged to the corresponding four base plates 28 with hinged arms 37, so that when the threaded rod 32 rotates to drive the sliding block 33 to slide, the hinged arm 37 pushes the base plate 28 to slide.

[0064] In this embodiment, an axle rod 31 is rotatably mounted on the front end cover 2 and the rear end cover 3, and a threaded rod 32 is fixed at one end thereof close to each other. By rotating the axle rod 31, the threaded rod 32 can be driven to rotate synchronously. The sliding block 33 threadedly sleeved on the threaded rod 32 will slide along its axial direction as the threaded rod 32 rotates. At the same time, the supporting seat 24 fixedly mounted on the inner walls of both sides of the neck tube 1 and the rectangular guide opening 25 and the rectangular slide bar 26 thereon are connected to the base plate 28 through the hinge arm 37. When the sliding block 33 slides, the base plate 28 and the running wheel 30 thereon can be pushed to slide along the direction of the contraction opening 24 through the transmission effect of the hinge arm 37, thereby adjusting the extension length of the running wheel 30.

[0065] The threaded rod 32, the sliding block 33, the second support seat 34, the second rectangular guide 35, the second rectangular slide bar 36 and the articulated arm 37 are organically combined to form a compact and efficient walking mechanism structure layout. This layout not only reduces the space occupied inside the equipment, but also improves the collaborative working efficiency between the various components.

[0066] The smooth extension and retraction of the travel wheel 30 is achieved through the transmission of the screw drive and the articulated arm 37. This design reduces the risk of equipment shaking and damage caused by improper manual operation, and improves the stability and durability of the equipment. At the same time, the connection between the various components is also more firm and reliable, ensuring the stable operation of the equipment during long-term use.

[0067] In a further preferred embodiment of the present invention, a synchronous shaft 38 is fixedly installed in the neck tube 1, and two pulleys 39 are fixedly sleeved on both ends of the synchronous shaft 38 and the two threaded rods 32, and the four pulleys 39 are sleeved with synchronous belts 40 in pairs.

[0068] In this embodiment, in order to realize the synchronous rotation control of the two threaded rods 32, a synchronous shaft 38 is fixedly installed inside the neck tube 1. Pulleys 39 are fixedly sleeved on both ends of the synchronous shaft 38 and the two threaded rods 32, and these pulleys 39 are connected in pairs by synchronous belts 40 to form a closed-loop transmission system. When it is necessary to adjust the extension length of the running wheel 30, the user only needs to drive the synchronous shaft 38 to rotate (for example, by an external motor or a manual crank, etc.), and the rotation of the synchronous shaft 38 will drive the pulleys 39 on it to rotate, and then the rotational power will be transmitted to the pulleys 39 on the two threaded rods 32 through the synchronous belt 40, so that the two threaded rods 32 rotate synchronously. With the rotation of the threaded rod 32, the sliding block 33 will slide along the axial direction of the threaded rod 32, and through the transmission effect of the articulated arm 37, the base plate 28 and the running wheel 30 are pushed to slide along the direction of the contraction port 24, so as to adjust the extension length of the running wheel 30.

[0069] The synchronous rotation control of the two threaded rods 32 is achieved through the transmission system composed of the synchronous shaft 38, the second pulley 39 and the second synchronous belt 40. This design ensures that the two sides of the running wheel 30 can be kept synchronized when adjusting the extension length, avoiding the problem of equipment shaking or tilting due to asynchrony, and improving the stability and safety of the equipment.

[0070] The user only needs to drive the synchronization shaft 38 to rotate to complete the synchronization control of the two threaded rods 32, without having to operate each threaded rod 32 separately, which greatly simplifies the operation process. This design reduces the user's operating difficulty and labor intensity and improves work efficiency.

[0071] In a further preferred embodiment of the present invention, an operating wheel 41 is disposed outside the rear end cover 3 , and the operating wheel 41 is fixedly connected to the corresponding shaft member 31 .

[0072] In this embodiment, in order to more conveniently control the extension length of the running wheel 30, an operating wheel disc 41 is additionally provided on the outside of the rear end cover 3. The operating wheel disc 41 is fixedly connected to the shaft member 31, so the user can indirectly drive the shaft member 31 to rotate by rotating the operating wheel disc 41. As the shaft member 31 rotates, the threaded rod 32 thereon will also rotate synchronously, and then through the transmission effect of the synchronous belt 2 40 and the pulley 2 39, the sliding blocks 33 on the two threaded rods 32 slide along their axial direction. This sliding process pushes the base plate 28 and the running wheel 30 to slide along the direction of the contraction opening 24 through the transmission effect of the articulated arm 37, thereby adjusting the extension length of the running wheel 30.

[0073] The introduction of the operating wheel 41 allows the user to adjust the extension length of the running wheel 30 directly outside the device by rotating the operating wheel 41 without entering the device or looking for other operating tools. This design greatly improves the convenience and intuitiveness of operation and reduces the difficulty and complexity of operation.

[0074] By rotating the operating wheel 41 to control the extension length of the running wheel 30, the user can adjust the supporting state of the equipment at any time according to actual needs to adapt to steel structure pipes of different diameters and shapes. This flexible operation mode not only improves work efficiency, but also enhances user experience satisfaction and comfort.

[0075] In a further preferred embodiment of the present invention, the distribution box 5 contains a battery and a controller, which is connected to the laser rust removal gun 7.

[0076] In this embodiment, the power distribution box 15 integrates the core components of the battery and the controller, which together provide power and control signals for the laser rust removal gun 7. The user sends instructions to the controller by operating the controller (which may be located in other parts of the device, such as the operating handle 23 or through a wireless remote control), and the controller controls the battery to supply power to the laser rust removal gun 7 according to the instructions, and may adjust the power supply voltage, current and other parameters to meet different rust removal requirements. After the laser rust removal gun 7 receives power, its internal laser generator is activated to generate a high-intensity laser beam to remove rust from the surface of the steel structure pipe fittings.

[0077] The battery integrated in the power distribution box 5 provides an independent power source for the laser rust removal equipment, so that the equipment can operate without relying on an external power supply. This design greatly improves the portability and self-sustaining power of the equipment, allowing the equipment to perform rust removal operations at sites without power supply or in high altitude, narrow and other environments where it is difficult to access power.

[0078] Through the precise control of the battery power by the controller, the user can finely adjust the output power of the laser rust removal gun 7 to adapt to steel structure pipes of different materials, thicknesses and degrees of corrosion. This improvement in control accuracy and flexibility helps to ensure the consistency and stability of the rust removal effect, while reducing energy waste and equipment loss.

[0079] In order to further improve the use effect of the device, in addition to the above scheme, this scheme also has the following embodiments:

[0080] In another embodiment of the present invention, the walking mechanism further includes a power transmission shaft 1 42, a friction roller 43, a driven bevel gear 44, a power transmission shaft 2 45, a driving bevel gear 46, a power long shaft 47, a synchronous sliding cylinder 48, a synchronous hanging plate 61, a deviation correction sliding port 49, a deviation correction sliding synchronous block 50, two pulleys 3 51, a synchronous belt 3 52, a motor housing 53, a walking motor 54, two pulleys 4 55 and a synchronous belt 4 56, and the power transmission shaft 1 42 can be rotatably mounted on one of the wheel axle plates 2 corresponding to the front end cover 2 9, the friction roller 43 and the driven bevel gear 44 are both fixedly sleeved on the power transmission shaft 1 42, the friction roller 43 is in frictional contact with the walking wheel 30, and is used to drive the walking wheel 30 to rotate, the power transmission shaft 2 45 can be rotatably mounted on the base plate 28 corresponding to the power transmission shaft 1 42, the active bevel gear 46 is fixedly mounted on the power transmission shaft 2 45, the power long shaft 47 can be rotatably mounted in the front end cover 2, and the setting direction of the power long shaft 47 is consistent with the sliding direction of the base plate 28, The synchronous sliding cylinder 48 can be slidably mounted on the power long shaft 47, the synchronous hanging plate 61 can be rotatably mounted on the synchronous sliding cylinder 48 and fixedly connected to the corresponding base plate 28, the correcting sliding opening 49 is opened on the power long shaft 47, the correcting sliding synchronous block 50 can be slidably installed in the correcting sliding opening 49, the correcting sliding synchronous block 50 is fixedly connected to the synchronous sliding cylinder 48, the correcting sliding synchronous block 50 slides along the correcting sliding opening 49 in the same direction as the sliding direction of the base plate 28, and the two leather The pulley three 51 is fixedly mounted on the synchronous sliding cylinder 48 and the power transmission shaft two 45 respectively, the synchronous belt three 52 is mounted on the two pulleys three 51, the motor housing 53 is fixedly mounted on the outer side of the front end cover 2, the travel motor 54 is fixedly mounted in the motor housing 53, the travel motor 54 is connected to the distribution box two 22, the two pulleys four 55 are fixedly mounted on the power long shaft 47 and the driving shaft of the travel motor 54 respectively, and the synchronous belt four 56 is mounted on the two pulleys four 55.

[0081] In this embodiment, the walking mechanism is further improved, and power transmission and automatic deviation correction functions are added. When the equipment needs to move automatically, the walking motor 54 is started, and the power shaft 47 is driven to rotate through the transmission action of the synchronous belt 4 56 and the pulley 4 55. The rotation of the power shaft 47 further drives the synchronous sliding cylinder 48 to slide on the power shaft 47. Since the synchronous sliding cylinder 48 is fixedly connected to the synchronous hanging plate 61, and the synchronous hanging plate 61 is connected to the base plate 28, the base plate 28 will slide along the direction of the power shaft 47 with the synchronous sliding cylinder 48. At the same time, since the deviation correction sliding synchronization block 50 is fixedly connected to the synchronous sliding cylinder 48 and can slide in the deviation correction sliding port 49, this design ensures that the base plate 28 can maintain a stable posture during the sliding process to prevent deflection.

[0082] As the base plate 28 slides, the running wheel 30 gradually extends and contacts the inner wall of the steel structure pipe. At this time, the friction roller 43 on the power transmission shaft 1 42 contacts the running wheel 30 by friction, and the running wheel 30 is driven to rotate by friction, thereby pushing the device forward inside the pipe. At the same time, the rotation of the power transmission shaft 1 42 also drives the driven bevel gear 44 to rotate, and through the transmission action of the synchronous belt 3 52 and the pulley 3 51, the power is transmitted to the driving bevel gear 46 on the power transmission shaft 2 45, thereby realizing further transmission and distribution of power.

[0083] The travel motor 54 provides power, and after being transmitted and amplified by a multi-stage transmission device (such as a synchronous belt, a pulley, a bevel gear, etc.), the travel wheel 30 can obtain sufficient driving force to achieve stable and fast travel inside the steel structure pipe. This design improves the travel efficiency and reliability of the equipment and reduces the difficulty and intensity of manual operation.

[0084] The design of the correcting sliding opening 49 and the correcting sliding synchronous block 50 enables the base plate 28 to automatically correct during the sliding process and maintain a stable posture and direction. This automatic correcting function helps to reduce the shaking and deflection of the equipment during the walking process and improve the accuracy and stability of the rust removal operation.

[0085] In another embodiment of the present invention, a conductive mechanism is provided on the neck of the neck tube 1, and the conductive mechanism includes an insulating inner ring 57 fixedly sleeved on the neck of the neck tube 1, and an insulating outer ring 58 fixedly connected to the distribution box 5 is provided outside the insulating inner ring 57, and a conductive ring 1 59 is embedded on the outside of the insulating inner ring 57, and a conductive ring 2 60 is embedded on the inside of the insulating outer ring 58, and the conductive ring 2 60 is in conductive sliding contact with the conductive ring 1 59.

[0086] In this embodiment, in order to enhance the adaptability and safety of the device in a specific working environment, a conductive mechanism is added to the neck of the neck tube 1. The conductive mechanism is mainly composed of an insulating inner ring 57, an insulating outer ring 58, a conductive ring 1 59 and a conductive ring 2 60. The insulating inner ring 57 is fixedly sleeved on the neck of the neck tube 1 to isolate the current and protect the internal structure. The insulating outer ring 58 is fixedly connected to the distribution box 1 5 to ensure that the electrical connection between the conductive mechanism and other parts of the device is stable and reliable. The conductive ring 1 59 is embedded in the outside of the insulating inner ring 57, and the conductive ring 2 60 is embedded in the inside of the insulating outer ring 58, and the two realize the transmission of current through conductive sliding contact.

[0087] During use, when the device needs to be electrically connected to an external power source or other electrical equipment, it can be done through the conductive mechanism. The wire of the external power source or electrical equipment can be connected to the conductive ring 1 59, and the conductive ring 2 60 is connected to the battery in the distribution box 1 5. Due to the conductive sliding contact between the two, the current can smoothly pass through the conductive mechanism into the device, providing the required power support for the device.

[0088] The design of the conductive mechanism fully considers the safety and reliability of the electrical connection. The setting of the insulating inner ring 57 and the insulating outer ring 58 effectively isolates the current, prevents the current from directly affecting the internal structure of the equipment, and avoids the occurrence of electrical failures and safety accidents. At the same time, the conductive sliding contact between the conductive ring 1 59 and the conductive ring 2 60 ensures the smooth and stable current transmission and improves the reliability of the electrical connection.

[0089] In summary, compared with the relevant technologies, the present device realizes efficient, comprehensive and flexible rust removal operations inside steel structure pipe fittings as a whole. By adopting innovative structural designs such as the neck tube 1, the front end cover 2, the rear end cover 3 and the rotatable rotating ring 4, the equipment can easily adapt to pipe fittings of different specifications and lengths, ensuring that the laser rust removal gun 7 can penetrate into the interior of the pipe fittings and perform all-round, no-dead-angle rust removal on the inner wall. The high energy density and rapid gasification characteristics of laser rust removal technology make the rust removal process rapid and thorough, greatly improving the operating efficiency and cleanliness. At the same time, the equipment has a reasonable structural design and is easy to operate, providing users with a convenient, efficient and reliable rust removal solution. Compared with the relevant technologies, the present device has significantly improved rust removal efficiency, adaptability and ease of operation, effectively reducing labor costs and time costs, and improving economic and environmental benefits.
