Description

Technical Field

[0001] The invention relates to the technical field of laser repair, and in particular to a tower rust removal laser engraving and repairing device. Background Art

[0002] The common flat laser engraving instruments on the market are mainly designed for drawing patterns on flat surfaces, such as walls and desktops. These devices are usually equipped with a flat guide system to ensure the precise movement of the laser head on a two-dimensional plane. However, this design is powerless when facing non-flat surfaces, especially arc-shaped surfaces. Due to the constraints of the flat guide, these laser engravers or painters cannot adapt to the geometric characteristics of the curved surface, which greatly limits their application on cylindrical or conical objects.

[0003] In addition, existing laser engraving technology also faces challenges when dealing with high-altitude operations, such as the maintenance and repair of wind turbine towers. Traditional flat laser engraving equipment cannot adapt to the complexity and safety requirements of high-altitude operations, especially when rust removal, engraving and repair of the tower surface are required.

[0004] In order to solve these problems, the present invention proposes a split flexible constrained arc 4-DOF tower rust removal laser engraving and repairing device based on annular guide rails. The device adopts an innovative mechanical structure design, which enables it to adapt to the operation requirements of cylindrical and conical surfaces. Through the combination of spiral ascending and descending mechanisms, inkjet plotter cartridge actuators, and rust removal / laser engraving / repair actuators, the device can achieve all-round operation on complex curved surfaces while maintaining high precision. Summary of the invention

[0009] As a preferred solution of the tower rust removal laser engraving and repairing device described in the present invention, the annular guide rail includes a plurality of first arc guide rails, each of which is interconnected by an elastic belt, and the tension of the elastic belt is controlled by a first servo motor.

[0010] As a preferred solution of the tower rust removal laser engraving and repairing device of the present invention, the first arc guide rail is provided with four sections or eight sections.

[0012] As a preferred solution of the tower rust removal laser engraving and repairing device described in the present invention, the lifting distance is determined by the number of rotations of the walking wheel, and infrared rangefinders are respectively installed at the upper and lower ends of the tower to cooperate with the number of rotations of the walking wheel to prevent overtravel.

[0017] As a preferred solution of the tower rust removal laser engraving and repairing device described in the present invention, the processing component is located above the walking component along the up and down direction of the tower. Since the tower is conical, the second arc guide rail and the first arc guide rail may not be on the same straight line.

[0018] Beneficial effects of the present invention: The present invention solves the problem that existing planar laser engraving instruments cannot adapt to cylindrical or conical surfaces by innovatively sleeved annular guide rails on the outer wall of the tower.

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0031] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0032] Example 1

[0033] Reference Figure 1-Figure 3 , which is the first embodiment of the present invention, provides a tower rust removal laser engraving and repairing device, including a walking component 100, including an annular guide rail 101 and a plurality of walking wheels 102 installed inside the annular guide rail 101; a processing component 200, installed on the walking component 100, which includes a moving part 201 moving along the outer wall of the annular guide rail 101, a lifting part 202 is arranged on the moving part 201, and an infrared rangefinder, a laser rust removal head or a laser repair nozzle is installed on the lifting part 202.

[0034] Since existing planar laser engraving instruments are limited to planes and cannot adapt to the operation requirements of non-planar surfaces such as cylindrical or conical surfaces, we have designed a new tower rust removal laser engraving and repair instrument to overcome these limitations and expand the application scope of laser engraving technology. The design concept of the ring guide 101 system is based on the adaptability to towers of different sizes and the need to operate the tower surface at multiple angles and in multiple ways.

[0035] We have proposed an innovative solution: by sleeve-mounting an annular guide rail 101 on the outer wall of the tower, the annular guide rail 101 is composed of multiple sections of first arc-shaped guide rails 101a and elastic bands 101b connected end to end at intervals. This design allows the guide rail system to be flexibly adjusted to adapt to towers of different diameters and sizes. The inner wall of each first arc-shaped guide rail 101a is provided with a Mack wheel-type running wheel 102. This special wheel design allows the equipment to move horizontally, vertically, and spirally on the outer wall of the tower. Due to the unique structure of the Mack wheel, the equipment can achieve all-round movement without changing the direction of the wheel, including horizontal movement along the outer wall of the tower, vertical climbing, and spiral climbing. This all-round mobility enables the laser rust removal head or laser repair nozzle installed on the annular guide rail 101 to perform precise operations on the tower body, whether it is rust removal, engraving or repair work, it can be completed efficiently.

[0036] Therefore, this system based on the ring rail 101 not only solves the application limitations of traditional laser engraving instruments on non-planar surfaces, but also improves the flexibility and efficiency of operations, especially in the maintenance and repair of complex structures such as high-altitude towers, showing its unique advantages. Through this innovative design, we can provide a new and efficient solution for tower maintenance, thereby improving the operating standards of the entire industry.

[0037] Example 2

[0038] Reference Figure 1-Figure 5 , which is the second embodiment of the present invention, and this embodiment is different from the first embodiment in that: the annular guide rail 101 includes a plurality of first arc-shaped guide rails 101a, each of which is linked to another by an elastic belt 101b, and the elastic belt 101b is controlled in tension by a first servo motor 101c. A plurality of running wheels 102 are installed inside each first arc-shaped guide rail 101a, and the first arc-shaped guide rail 101a is provided with four or eight sections as required.

[0039] The design of the annular guide rail 101 is to adapt to the outer wall operation of the tower (cylindrical or conical structure), such as the maintenance and repair of the tower. This annular guide rail 101 is composed of a plurality of first arc-shaped guide rails 101a, which can be adjusted and assembled according to the size and shape of the tower. The following is an explanation and description:

[0040] The annular guide rail 101 is composed of a plurality of first arc-shaped guide rails 101a, each of which is equipped with a plurality of running wheels 102 on the inner side to support the smooth movement of the equipment on the surface of the tower. These arc-shaped guide rails are interconnected by elastic bands 101b, which provide the necessary flexibility so that the guide rail system can adapt to the curvature changes of the tower. A first servo motor 101c is installed at the end of each first arc-shaped guide rail 101a to control the tension of the elastic band 101b to ensure that there is appropriate friction between the equipment and the surface of the tower, thereby maintaining stability and accuracy during movement. In actual operation, by accurately controlling the first servo motor 101c, the tension of the elastic band 101b can be dynamically adjusted to adapt to the curvature changes of the tower surface, ensuring that the equipment can perform precise operations on towers of different diameters and tapers, such as laser rust removal, engraving or repair operations. This design not only improves the flexibility and efficiency of the operation, but also ensures the accuracy of the operation on complex geometric shapes, providing an innovative solution for tower maintenance.

[0041] Adaptability of the guide rail system: Since the first curved guide rail 101a can be set to four or eight sections as needed, this design enables the guide rail system to adapt to towers of different diameters and heights. By increasing or decreasing the number of sections of the curved guide rail, the total length and curvature of the guide rail system can be adjusted to match the specific size of the tower.

[0042] In summary, the design of the annular guide rail 101 system fully considers the special needs of tower maintenance and repair operations, and achieves efficient and precise operations on complex curved surfaces through modular and dynamically adjustable designs.

[0043] The travel wheel 102 is a plurality of synchronous wheels tilted at an angle of 45 degrees to the horizontal / vertical position, which adopts a hub motor to control its movement, and is preferably a Macomb wheel. When designing equipment for working on the surface of cylindrical or conical structures such as towers, the selection and configuration of the travel wheel 102 are crucial because they directly affect the mobility and operating stability of the equipment. Our equipment uses a plurality of synchronous wheels tilted at an angle of 45 degrees to the horizontal / vertical position as the travel wheel 102. This design enables the equipment to move in multiple directions on the surface of the tower, including horizontal, vertical and spiral paths. These synchronous wheels are preferably Macomb wheels, because Macomb wheels have unique omnidirectional movement capabilities, and they can achieve multi-directional movement without changing the direction of the wheel. The design of this wheel makes the movement of the equipment on the surface of the tower more flexible and precise, especially when performing spiral ascent or descent operations, the Macomb wheel can provide better controllability and adaptability.

[0044] In order to further improve the stability and shock absorption effect of the equipment during movement, we added a shock absorber frame to the installation structure of the synchronous wheel. The shock absorber frame consists of an elastic element (such as a spring) and a fixed frame, and the fixed frame is fixed to the inner wall of the first arc-shaped guide rail 101a. Through this design, the shock absorber frame can filter the vibration during the walking process, reducing the impact of the vibration caused by the uneven tower surface or the movement of the equipment on the operation accuracy; on the other hand, it can always keep the synchronous wheel against the outer wall of the tower, ensuring that the equipment maintains good contact with the tower surface when spirally rising or descending, thereby further ensuring the friction performance and movement stability of the machine.

[0045] In addition, each synchronous wheel uses a hub motor to control its movement. This direct drive method not only improves the accuracy of movement, but also enhances the equipment's adaptability to different tower surface conditions. The use of hub motors also simplifies the transmission system, reduces maintenance requirements, and improves overall operating efficiency.

[0046] In summary, by using a 45-degree inclined Mack wheel synchronous wheel, equipped with a shock-absorbing frame and using hub motor control, our equipment can achieve efficient, stable and precise movement on the tower surface, maintaining excellent operating performance whether on a horizontal, vertical or spiral path. This design not only improves the operational flexibility of the equipment, but also ensures the accuracy and stability of operations on complex curved surfaces, providing an innovative and efficient solution for tower maintenance and repair operations.

[0047] The lifting distance is determined by the number of revolutions of the running wheel 102. Infrared rangefinders are installed at the upper and lower ends of the tower to coordinate with the number of revolutions of the running wheel 102 to prevent overtravel.

[0048] When designing equipment for working on cylindrical or conical structural surfaces such as towers, it is very important to accurately control the lifting distance of the equipment to ensure the accuracy and safety of the operation. To this end, our equipment adopts a method for determining the lifting distance based on the number of rotations of the walking wheel 102, supplemented by an infrared rangefinder for position monitoring to prevent the equipment from overtravel.

[0049] Relationship between the number of rotations of the running wheel 102 and the lifting distance: The movement of the equipment depends on the rotation of the running wheel 102 (such as a Mack wheel or other wheels suitable for curved surface movement). The number of rotations of each running wheel 102 is directly related to the distance the equipment moves along the tower surface. By accurately calculating the circumference and number of rotations of the running wheel 102, we can determine the exact distance the equipment rises or falls. This method provides high-precision movement control and ensures the accuracy of the operation.

[0050] Application of infrared rangefinders: In order to further improve the accuracy of position control and prevent equipment from overtravel, we installed infrared rangefinders at the upper and lower ends of the tower. These rangefinders monitor the distance between the equipment and the top and bottom of the tower in real time, providing an additional safety measure.

[0051] The data of the infrared rangefinder is combined with the number of rotations of the running wheel 102 to realize dual monitoring of the equipment position. If the equipment approaches the top or bottom of the tower, the rangefinder will send a signal, and the equipment control system will adjust the rotation of the running wheel 102 according to these signals to prevent the equipment from exceeding the predetermined operating range.

[0052] Control logic to prevent overtravel: The control system of the equipment will comprehensively consider the number of rotations of the travel wheel 102 and the data of the infrared rangefinder to achieve precise position control. If the rangefinder detects that the equipment is close to the extreme position of the tower, the control system will immediately adjust the rotation speed or direction of the travel wheel 102, or even stop moving, to prevent the equipment from overtravel. This control logic not only improves the safety of the operation, but also ensures the continuity and efficiency of the operation, avoiding potential risks and operation interruptions caused by equipment overtravel.

[0053] By combining the control method of the number of rotations of the running wheel 102 and the infrared rangefinder, our equipment can achieve accurate and safe lifting operations on complex structures such as towers. This method not only improves the accuracy and safety of the operation, but also enhances the adaptability and reliability of the equipment, enabling it to operate stably under various environmental conditions.

[0054] In order to clearly describe the working process of the spiral rising and descending mechanism along the outer wall of the tower (cylindrical or conical), we can break it down into the following steps:

[0055] 1. Initialize the equipment: First, correctly install 4-8 synchronous wheels (using hub motors) on 4 or 8 first arc-shaped guide rails 101a, and then connect two adjacent first arc-shaped guide rails 101a through elastic bands 101b, which are installed on the first servo motor 101c at the port of each first arc-shaped guide rail 101a. Then install the moving part 201, the lifting part 202, the infrared rangefinder, the laser rust removal head or the laser repair nozzle, etc. in sequence. The equipment is installed at the bottom of the target tower (cylinder or cone), and the size and number of these first arc-shaped guide rails 101a and elastic bands 101b are determined according to the minimum and maximum diameters of the tower.

[0056] 2. Tightening and loosening the first arc-shaped guide rail 101a: The tension of the elastic band 101b is controlled by the first servo motor 101c to ensure stable and reliable friction between the first arc-shaped guide rail 101a.

[0057] 3. Start the ascending or descending process: Start the hub motor to rotate the synchronous wheel, driving the entire device to spirally ascend or descend along the outer wall of the cylinder or cone. The ascending or descending distance of the device is accurately controlled by the number of revolutions of the synchronous wheel. Before use, the infrared rangefinder installed at the top and bottom of the tower monitors the position of the device in real time to prevent the device from overtravel.

[0058] 4. Execution of the processing component 200: During the process of the equipment rising or falling, the motor adjusts the position of the processing component 200 according to the taper of the tower, ensuring that the processing component 200 can accurately operate on the tapered object.

[0059] 5. Complete the operation: Once the equipment reaches the predetermined position or completes the operation, stop the hub motor, stop the equipment from moving, and turn off all motors and sensors to ensure the safety of the equipment.

[0060] Through the above steps, the equipment can accurately spiral up and down along the outer wall of the tower while performing painting or other operations. This design not only improves the flexibility and efficiency of the operation, but also ensures the accuracy of operation on complex geometric shapes.

[0061] The remaining structures are the same as those of Example 1.

[0062] Example 3

[0063] Reference Figure 1-Figure 5 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that the outer wall of each first arcuate guide rail 101a is provided with a second arcuate guide rail 204, the arcuate seat 201a of the moving member 201 slides along the second arcuate guide rail 204, and a second servo motor is installed in the arcuate seat 201a, and a limit switch is provided at the end of the second arcuate guide rail 204.

[0064] The horizontal movement of the equipment is achieved through the second curved guide rail 204 and the moving part 201, allowing the equipment to further move left and right on the outer surface of the tower (when the running wheels 102 are not moving). The outer wall of each first curved guide rail 101a is provided with a second curved guide rail 204, and this design is to provide a special path so that the moving part 201 of the equipment can move horizontally along this path. The second curved guide rail 204 is combined with the first curved guide rail 101a to form a complex guide rail system, allowing the equipment to move in multiple directions on the surface of the tower.

[0065] The arc seat 201a of the moving member 201 is a component that slides along the second arc guide rail 204, and is responsible for carrying and moving a specific part of the device, such as a laser rust removal head or other working tools. A second servo motor is installed inside the arc seat 201a, and this motor directly drives the roller connected to it. When the second servo motor is working, it moves in the second arc guide rail 204 through the roller, thereby driving the arc seat 201a to move left and right along the second arc guide rail 204.

[0066] In order to ensure the safe movement of the moving member 201 on the second arc-shaped guide rail 204 and prevent it from exceeding the predetermined range, a limit switch is provided at the end of the guide rail. The limit switch sends a signal when the moving member 201 reaches the limit position of the guide rail. After receiving the signal, the control system stops the operation of the second servo motor, thereby preventing the moving member 201 from exceeding the range of the guide rail and avoiding possible damage or safety accidents.

[0067] This design allows the equipment to perform precise horizontal movement on the tower surface while ensuring safe operation. The second servo motor provides precise control, allowing the moving part 201 to move along a predetermined path and speed, while the limit switch provides additional safety for the entire system. This precise drive and control system is the key to achieving precise operation of the equipment on complex curved surfaces.

[0068] The lifting member 202 includes a linear slide 202a installed on the arc seat 201a, and a lead screw 202b parallel to the linear slide 202a is also provided on the arc seat 201a. The linear slide 202a slides with a slide seat 202c and is screwed with the lead screw 202b to control its movement. A third servo motor 202d is installed at one end of the lead screw 202b. Another set of lifting members 202 can be installed on the inner side or outer side of the slide seat 202c. The number of lifting members 202 is determined according to the number of infrared rangefinders, laser rust removal heads or laser repair nozzles.

[0069] The lifting and lowering movement of the equipment is achieved through a precision lead screw 202b and slide rail system, which allows equipment such as laser rust removal heads or other working tools to perform further lifting operations on the surface of towers or other cylindrical structures. The following is a combined explanation of the content:

[0070] The lifting member 202 includes a linear guide rail 202a mounted on an arc seat 201a. This guide rail provides a linear path for the lifting movement of the device. A lead screw 202b parallel to the linear guide rail 202a is also provided on the arc seat 201a. This lead screw 202b works together with the linear guide rail 202a to control the precise movement of the slide 202c. A slide 202c slides on the linear guide rail 202a, and the slide 202c is screwed by the lead screw 202b, which means that the rotation of the lead screw 202b will directly control the movement of the slide 202c along the linear guide rail 202a. By controlling the third servo motor 202d, the rotation of the lead screw 202b can be precisely adjusted, thereby realizing the lifting movement of the slide 202c. A third servo motor 202d is installed at one end of the lead screw 202b, which is the power source of the entire lifting system. By controlling the rotation of the third servo motor 202d, the lead screw 202b can be driven to rotate accurately, thereby controlling the slide 202c to rise or fall along the linear guide rail 202a.

[0071] Expandability of arc guide rails, moving parts 201, and lifting parts 202: Another set of arc guide rails, moving parts 201, and lifting parts 202 can be installed on the inner side or outer side of the slide 202c as needed. This design provides expandability of the system and can add more working tools according to the working requirements. The number of arc guide rails, moving parts 201, and lifting parts 202 can be determined according to the number of infrared rangefinders, laser rust removal heads, or laser repair nozzles to adapt to different working scenarios and requirements.

[0072] This motion mechanism enables the equipment to precisely adjust the height of the laser rust removal head or other working tools to adapt to different working points on the tower surface. Whether it is fine laser rust removal or complex repair work, this precise control is crucial. Through this design, the equipment can further perform precise lifting and lowering operations on the tower surface while ensuring operational flexibility and scalability. This precise drive and control system is the key to enabling the equipment to perform precise operations on complex curved surfaces.

[0073] In our equipment design, infrared rangefinders, laser rust removal heads or laser repair nozzles are key operating tools, which are precisely installed at both ends of the lifting member 202 or on the slide 202c to achieve efficient operation on the surface of cylindrical structures such as towers. The installation position of these tools allows them to operate within the moving range of the entire lifting member 202, providing great flexibility and coverage. This design not only allows the operating tools to adjust their height according to the specific conditions of the tower surface to achieve the best operating effect, but also ensures the accuracy and safety of the operation.

[0074] The infrared rangefinder plays a vital role in this process. It monitors the distance between the working tool and the tower surface in real time to ensure that the laser rust removal head or laser repair nozzle maintains an appropriate distance from the working surface. This is crucial for the accuracy and safety of laser rust removal or repair work, because the correct distance can ensure the intensity and effect of the laser and avoid damage to the tower surface or uneven repair.

[0075] In addition, this design allows the tools to work together, improving the efficiency and quality of the work. For example, when performing laser rust removal, the infrared rangefinder can monitor and adjust the distance between the laser rust removal head and the tower surface in real time to ensure the rust removal effect; and when performing repair or coating operations, the laser repair nozzle can adjust the spraying distance according to the data of the rangefinder to ensure the uniformity of the coating. Through this precise control and real-time monitoring, our equipment can perform high-quality maintenance and repair operations on complex curved surfaces such as towers, ensuring the accuracy and efficiency of the operation.

[0076] The processing component 200 is located above the walking component 100 along the up-down direction of the tower. Since the tower is conical, the second arc guide rail 204 and the first arc guide rail 101a may not be on the same straight line.

[0077] When designing equipment for conical tower surface treatment, considering the geometric characteristics of the tower, we specially arranged the processing components 200 (such as laser rust removal heads or laser repair nozzles) along the up and down directions of the tower to be located above the walking components 100 (wheels or walking mechanisms responsible for the movement of the equipment on the tower surface). This layout is to adapt to the conical shape of the tower, in which the diameter of the tower gradually decreases from the bottom to the top. Therefore, the second arc guide rail 204 (the guide rail responsible for horizontal movement) and the first arc guide rail 101a (the guide rail responsible for supporting and guiding the walking component 100) may not be on the same horizontal straight line, but are adjusted accordingly according to the taper of the tower. Such a design allows the processing component 200 to move up and down accurately on the entire surface of the tower while maintaining the optimal contact angle and distance with the tower surface, ensuring the uniformity and efficiency of the processing operation, and maintaining high-performance operation even when the tower diameter changes.

[0078] The remaining structure is the same as that of Example 2.

[0079] Importantly, it should be noted that the construction and arrangement of the present application shown in a plurality of different exemplary embodiments are only exemplary.
