[0003] Currently, plasma air gouging mainly relies on manual operation with handheld air gouging guns. Manual operation is easily affected by factors such as hand tremors and fatigue, resulting in large deviations in the depth of air gouging grooves and irregular bevel formation, leading to unstable construction quality.

[0019] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. Furthermore, in the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0022] Example 1 like Figures 1 to 5 As shown, the present invention provides an air planer, including a chassis 100, a walking mechanism 200, an adjusting mechanism 300, a swinging mechanism 400, an air planer torch 500, and an electrical control cabinet 600. The car body 100 is provided with a traveling mechanism 200 on both sides, which is used to drive the car body 100 to move. The car body 100 is provided with an adjustment mechanism 300, the adjustment mechanism 300 is provided with a swing mechanism 400, and the swing mechanism 400 is equipped with an air planer torch 500. The adjusting mechanism 300 can drive the swing mechanism 400 to move along the length and height of the car body 100, so as to drive the air planer torch 500 to move synchronously. The swing mechanism 400 can drive the air planer torch 500 to move along the width of the car body 100. The body shell 100 is also equipped with an electrical control cabinet 600, which is electrically connected to the adjustment mechanism 300 and the swing mechanism 400 respectively.

[0023] In this embodiment, the vehicle shell 100 serves as the supporting foundation for the entire equipment, providing an installation platform for various functional components. Traveling mechanisms 200 are provided on both sides of the vehicle shell 100. These mechanisms move the vehicle shell 100 on the working surface, enabling automatic movement and position adjustment of the equipment on the nuclear island containment surface, replacing manual hand-held operation. An adjustment mechanism 300 is provided on the vehicle shell 100, and a swing mechanism 400 is mounted on the adjustment mechanism 300. An air-cutting torch 500 is mounted on the swing mechanism 400. The adjustment mechanism 300 can drive the swing mechanism 400 to move along the length and height of the vehicle shell 100, thereby synchronously moving the air-cutting torch 500 and adjusting its position in the front-back and vertical directions. The swing mechanism 400 can drive the air-cutting torch 500 to move along the width of the vehicle shell 100, enabling the air-cutting torch 500 to swing laterally. By combining the longitudinal and vertical movement of the adjustment mechanism 300 with the lateral swing of the swing mechanism 400, the air planer torch 500 can achieve precise position control and trajectory movement in three-dimensional space, meeting the air planing operation needs of different bevel shapes and positions.

[0024] Correspondingly, an electrical control cabinet 600 is also installed on the shell 100, which is electrically connected to the adjustment mechanism 300 and the swing mechanism 400. The electrical control cabinet 600 integrates a controller and a power module, used to receive operating commands and control the movement of the adjustment mechanism 300 and the swing mechanism 400. Operators can operate the equipment remotely (such as with a wired remote control or a wireless remote control device), achieving physical isolation from the air planer operating area and avoiding radiation exposure risks. This embodiment realizes automated and remote operation of air planing, replacing the traditional manual hand-held operation method, fundamentally solving the technical problems of unstable quality and radiation exposure risks associated with manual operation.

[0025] According to one embodiment provided by the present invention, such as Figure 1 and Figure 2 As shown, the walking mechanism 200 includes two sets of walking components, which are respectively located on both sides of the vehicle body 100 along its width direction. Each set of walking components includes a drive shaft 201, a drive sprocket 202, a track 203, and a drive motor; Two drive shafts 201 are provided, which are mounted on both ends of the vehicle body 100 along the length direction of the vehicle body 100, and both ends of the drive shafts 201 protrude from the vehicle body 100. Each drive shaft 201 has a drive sprocket 202 sleeved on both ends, and a track 203 is sleeved on the outside of the drive sprocket 202. The drive sprocket 202 meshes with the track 203, and a magnetic attraction unit is provided in the track plate of the track 203. The body shell 100 is also equipped with a drive motor, and the output end of the drive motor is connected to the drive sprocket 202 for transmission.

[0026] In this embodiment, the traveling mechanism 200 includes two sets of traveling components, which are respectively disposed on both sides of the vehicle body 100 along its width direction. Specifically, each set of traveling components includes a drive shaft 201, a drive sprocket 202, a track 203, and a drive motor. Two drive shafts 201 are provided, symmetrically arranged at both ends of the vehicle body 100 along its length direction, i.e., one drive shaft 201 is provided at each of the front and rear ends of the vehicle body 100. Both ends of the drive shaft 201 protrude from the sidewalls of the vehicle body 100, and each drive shaft 201 has a drive sprocket 202 mounted on both ends, i.e., two drive sprockets 202 are mounted on each drive shaft 201, located on the left and right sides of the vehicle body 100 respectively. A track 203 is fitted around the outside of the drive sprocket 202, and the drive sprocket 202 meshes with the track 203. When the drive sprocket 202 rotates, it drives the track 203 to move synchronously. The track 203 is equipped with a magnetic unit inside the track plate. The magnetic unit enables the track 203 to be attached to the surface of the steel containment vessel, providing sufficient adhesion to prevent the equipment from slipping or overturning due to gravity when operating on inclined or curved surfaces.

[0027] Preferably, a drive motor is also installed inside the vehicle body 100, and the output end of the drive motor is connected to the drive sprocket 202 for transmission. The drive motor provides power to the walking mechanism 200, and its output shaft is connected to the drive shaft 201 or the drive sprocket 202 through a reducer or a transmission chain. The drive motor can be a servo motor or a brushless DC motor, which has the characteristics of good speed regulation performance and high control precision.

[0028] During operation, the electrical control cabinet 600 controls the speed and direction of the drive motor according to the operating instructions. The drive sprocket 202 drives the track 203 to move. The magnetic unit on the track 203 is attracted to the surface of the containment vessel, and the equipment moves along the surface of the containment vessel under the drive of the track 203. The left and right walking components can be controlled independently. When the speeds of the drive motors on both sides are the same, the equipment moves in a straight line. When the speeds on both sides are different or the directions are opposite, the equipment turns. The track 203 type walking mechanism 200, together with the attraction force of the magnetic unit, enables the equipment to move and position stably on curved surfaces, inclined surfaces, and even inverted surfaces, meeting the operational requirements of the complex geometry of the nuclear island containment vessel.

[0029] According to one embodiment provided by the present invention, such as Figure 1 and Figure 2 As shown, each set of traveling components also includes a pressure sprocket 204, a handle 205, a spring seat 206, and a tension spring 207; The clamping sprocket 204 is mounted on the side wall of the vehicle body 100 via a driven shaft. One end of the handle 205 is rotatably connected to the vehicle body 100, and the other end is connected to the driven shaft of the clamping sprocket 204. The clamping sprocket 204 meshes with the track 203. The spring seat 206 is fixed to the side wall of the body 100. One end of the tension spring 207 is installed on the spring seat 206, and the other end abuts against the handle 205.

[0030] In this embodiment, the clamping sprocket 204 is mounted on the side wall of the vehicle body 100 via a driven shaft, located between the two drive sprockets 202 (i.e., between the drive shafts 201). The clamping sprocket 204 also meshes with the track 203, and its function is to apply downward pressure to the track 203, so that the track 203 forms a tight wrap between the drive sprocket 202 and the clamping sprocket 204, increasing the number of meshing teeth between the track 203 and the drive sprocket 202, and preventing the track 203 from skipping teeth during heavy loads or sudden stops.

[0031] One end of the handle 205 is rotatably connected to the vehicle body 100 (via a hinge shaft), and the other end is connected to the driven shaft of the pressure sprocket 204. The handle 205 can swing around its connection point with the vehicle body 100. When the handle 205 swings, the position of the pressure sprocket 204 changes accordingly, thereby adjusting the pressure of the pressure sprocket 204 on the track 203. The spring seat 206 is fixedly mounted on the side wall of the vehicle body 100. One end of the tension spring 207 is mounted on the spring seat 206, and the other end abuts against the handle 205. The tension spring 207 is always in a compressed state, and its elastic force is transmitted to the pressure sprocket 204 through the handle 205, so that the pressure sprocket 204 always has a tendency to move in the direction of the track 203, thereby continuously pressing the track 203. When the track 203 becomes loose due to long-term use, the elastic force of the tension spring 207 will automatically push the handle 205 to swing, causing the pressure sprocket 204 to further tighten the track 203, thus achieving automatic compensation of the track 203 tension. Alternatively, if there is a protrusion in the nuclear island containment structure, the above-mentioned configuration can still tension the track 203, allowing it to pass smoothly over the protrusion and then press firmly against the containment structure again.

[0032] According to one embodiment provided by the present invention, such as Figure 1 and Figure 3 As shown, the adjustment mechanism 300 includes a horizontal adjustment component and a height adjustment component; The horizontal adjustment component is located on the top of the body shell 100, and the horizontal adjustment component is equipped with a height adjustment component, and the height adjustment component is equipped with a swing mechanism 400. The horizontal adjustment component is used to drive the height adjustment component to move along the length direction of the body shell 100, and the height adjustment component is used to drive the swing mechanism 400 to move along the height direction of the body shell 100.

[0033] In this embodiment, the horizontal adjustment assembly is disposed on the top of the vehicle body 100, serving as the bottom component of the adjustment mechanism 300. A height adjustment assembly is mounted on the horizontal adjustment assembly, meaning the height adjustment assembly is installed on the horizontal adjustment assembly and moves along the length direction of the vehicle body 100. A swing mechanism 400 is mounted on the height adjustment assembly, meaning the swing mechanism 400 moves along the height direction of the vehicle body 100.

[0034] The horizontal adjustment component is used to move the height adjustment component along the length direction (i.e., the front-to-back direction) of the vehicle body 100, thereby realizing the horizontal longitudinal position adjustment of the air planer torch 500. This function allows the air planer torch 500 to achieve precise front-to-back positioning through the adjustment mechanism 300 without moving the entire vehicle, adapting to the air planing operation needs of different starting positions and different length bevels.

[0035] The height adjustment component is used to move the swing mechanism 400 along the height direction (i.e., the vertical direction) of the shell 100, thereby adjusting the vertical position of the air planer torch 500. This function allows the air planer torch 500 to adapt to the air planing needs of different thicknesses of containment wall panels and different depths of beveling, ensuring that the air planer torch 500 is always at the optimal working height.

[0036] Through the combination of horizontal and vertical adjustment components, the air gouging torch 500 can achieve precise position adjustment in both longitudinal and vertical degrees of freedom. During air gouging operations, these two adjustment axes can be linked with the lateral swing motion of the swing mechanism 400 to achieve precise control of complex spatial trajectories and meet the air gouging processing requirements of different parts and bevel shapes of the nuclear island containment.

[0037] According to one embodiment provided by the present invention, such as Figure 1 and Figure 3 As shown, the horizontal adjustment assembly includes a horizontal slide rail 301 and a horizontal slide block 302, and the height adjustment assembly includes a height slide rail 303 and a height slide block 304. The horizontal slide rail 301 is located on the top of the car body 100 and extends along the length of the car body 100. The horizontal slide block 302 is located at the bottom of the height slide rail 303 and can slide with the horizontal slide rail 301. The height slide rail 303 is located above the horizontal slide rail 301. The swing mechanism 400 is slidably connected to the height slide rail 303 through the height slide block 304. The height slide block 304 can slide and cooperate with the height slide rail 303.

[0038] In this embodiment, the horizontal slide rail 301 is disposed on the top of the vehicle body 100 and extends along the length of the vehicle body 100. The horizontal slide rail 301 can be a linear guide rail, which has high guiding accuracy and load-bearing capacity. The horizontal slide block 302 is disposed at the bottom of the height slide rail 303, and the horizontal slide block 302 can slide in cooperation with the horizontal slide rail 301. The horizontal slide block 302 contacts the horizontal slide rail 301 through a slider or roller, and can slide freely along the length of the horizontal slide rail 301. The horizontal slide block 302 can be driven by a motor-driven screw and nut mechanism to achieve precise position control.

[0039] The height slide rail 303 is positioned above the horizontal slide rail 301, extending along the height direction (i.e., vertical direction) of the vehicle body 100. The height slide rail 303 is fixedly connected to the horizontal slide block 302. When the horizontal slide block 302 slides along the horizontal slide rail 301, the entire height slide rail 303 moves synchronously. The swing mechanism 400 is slidably connected to the height slide rail 303 via the height slide block 304. The height slide block 304 can slide and engage with the height slide rail 303, moving up and down along the extending direction of the height slide rail 303. The swing mechanism 400 is fixedly mounted on the height slide block 304 and moves up and down with the height slide block 304.

[0040] During use, the horizontal adjustment component adjusts the longitudinal position of the air planer torch 500 by sliding the horizontal slide block 302 on the horizontal slide rail 301, and the height adjustment component adjusts the vertical position of the air planer torch 500 by sliding the height slide block 304 on the height slide rail 303. The sliding movement of the two adjustment shafts is driven by their respective drive motors (such as stepper motors or servo motors) through lead screws and nuts or gears 405 and racks 406, which can achieve precise closed-loop position control.

[0041] The driving and braking principles and specific structures of the height slide rail 303 and height slide block 304, and the horizontal slide rail 301 and horizontal slide block 302 are all existing technologies, so they will not be described in detail here.

[0042] According to one embodiment provided by the present invention, such as Figure 1 , Figure 3 and Figure 4 As shown, the swing mechanism 400 includes a base 401, a swing motor 402, a transmission assembly, and a connecting piece 403; The base 401 is connected to the height slide 304. The base 401 is equipped with a swing motor 402 and a transmission assembly is also provided inside the base 401. The output end of the swing motor 402 is connected to the transmission assembly, and the transmission assembly is also connected to the connecting piece 403. The bottom of the connecting piece 403 is provided with a clamping block 404, which can rotate relative to the connecting piece 403, and the air planer torch 500 is installed in the clamping block 404.

[0043] In this embodiment, a transmission assembly is also provided inside the base 401, and the output end of the swing motor 402 is connected to the transmission assembly for transmission. The transmission assembly is used to convert the rotational motion of the swing motor 402 into the linear swinging motion of the connecting piece 403.

[0044] The transmission assembly is also connected to the connecting plate 403, which transmits the oscillating motion to the air gouging torch 500. Specifically, an adapter 410 is provided at the end of the connecting plate 403. The adapter 410 is slidably mounted on the base 401 and is connected to the transmission assembly. The transmission assembly drives the adapter 410 to slide along the length of the base 401. A clamping block 404 is provided at the bottom of the connecting plate 403 for mounting the air gouging torch 500. The clamping block 404 can rotate relative to the connecting plate 403. This design allows the air gouging torch 500 to be finely adjusted around its own axis after installation, so as to adjust the attitude angle of the air gouging torch 500 relative to the workpiece and meet the requirements of different bevel angles and different air gouging processes.

[0045] The air planer torch 500 is installed inside the clamping block 404 and fixed to the connecting plate 403 by the clamping block 404. When the oscillating motor 402 drives the transmission assembly, the connecting plate 403 drives the clamping block 404 and the air planer torch 500 to oscillate back and forth along the width direction of the vehicle body 100, realizing the lateral oscillating motion of the air planer torch 500. This oscillating motion is the key motion for forming regular bevels in air planing operations. By controlling the oscillation amplitude and oscillation frequency, bevels of different widths and shapes can be obtained.

[0046] Optionally, at least one threaded hole is provided on the side wall of the adapter 410, and a strip hole is provided at the corresponding position of the connecting piece 403. By using a bolt to pass through the strip hole and thread it into the threaded hole, the connecting piece 403 and the adapter 410 are fixed. In other words, the height of the connecting piece 403 relative to the adapter 410 can be adjusted manually, thereby improving the overall applicability of the air planer.

[0047] According to one embodiment provided by the present invention, such as Figure 1 and Figure 4 As shown, the transmission assembly includes a gear 405 and a rack 406; The rack 406 is disposed inside the base 401 and extends along the length direction of the base 401, and a gear 405 meshes on the rack 406; Gear 405 is sleeved on the outside of the output shaft of the oscillating motor 402.

[0048] In this embodiment, a rack 406 is disposed inside a base 401 and extends along the length of the base 401 (i.e., the width of the body 100). The rack 406 is fixedly mounted on the inner wall of the base 401, with its teeth facing upwards or towards the gear 405. The gear 405 is sleeved on the outside of the output shaft of the oscillating motor 402 and is fixedly connected to the output shaft, rotating synchronously with it. The gear 405 meshes with the rack 406. When the oscillating motor 402 rotates, the gear 405 rotates accordingly. The rotational motion of the gear 405 is converted into linear motion along the length of the rack 406 through meshing with it.

[0049] Since the rack 406 is fixedly mounted on the base 401, when the gear 405 rolls on the rack 406, the gear 405 and the oscillating motor 402 are actually displaced relative to the rack 406 and the base 401. The adapter 410 is connected to the gear 405. This displacement is transmitted through the oscillating motor 402 to drive the gear 405, then to the adapter 410, and finally to the connecting piece 403, causing the connecting piece 403 to move along the length of the rack 406, thereby realizing the lateral oscillation of the air gouging torch 500.

[0050] By changing the rotation direction of the oscillating motor 402, the connecting piece 403 can move in both directions, forming a reciprocating oscillation. By controlling the rotation angle of the oscillating motor 402, the displacement of the connecting piece 403 can be precisely controlled, thereby controlling the oscillation amplitude of the air gouging torch 500. The gear 405 and rack 406 transmission has the advantages of precise transmission ratio, no slippage, and high rigidity, which can ensure the repeatability and trajectory consistency of the oscillating motion, making it suitable for air gouging beveling operations with high motion accuracy requirements.

[0051] According to one embodiment provided by the present invention, such as Figure 1 and Figure 4 As shown, a translation guide rail 407 is also provided inside the base 401, and a translation slide block 408 is slidably connected on the translation guide rail 407. A swing motor 402 is provided at the top of the translation slide block 408.

[0052] In this embodiment, the translation guide rail 407 is disposed inside the base 401 and extends along the length direction of the base 401 (i.e., the width direction of the vehicle body 100). The translation guide rail 407 can be a linear guide rail, which is fixedly installed on the inner wall of the base 401 and arranged parallel to the rack 406. The translation slide 408 is slidably connected to the translation guide rail 407 and can slide freely along the length direction of the translation guide rail 407. A swing motor 402 is provided at the top of the translation slide 408, that is, the swing motor 402 is fixedly installed on the translation slide 408. When the gear 405 rolls on the rack 406, the translation slide 408 together with the swing motor 402 slides along the translation guide rail 407.

[0053] According to one embodiment provided by the present invention, such as Figure 1 and Figure 3 As shown, the swing mechanism 400 also includes a locking handle 409, which is disposed on the base 401. The base 401 is detachably connected to the height slide 304 via the locking handle 409.

[0054] In this embodiment, the locking handle 409 is mounted on the side or top of the base 401. When the operator rotates or moves the locking handle 409, the locking mechanism of the locking handle 409 locks or releases the relative position between the base 401 and the height slide 304. The locking handle 409 is prior art known to those skilled in the art, therefore its specific internal structure and operating principle will not be described in detail.

[0055] When it is necessary to adjust the position of the swing mechanism 400 on the height slide 304, the operator loosens the locking handle 409, releasing the locking force between the base 401 and the height slide 304, allowing the base 401 to be removed from the height slide 304. The operator then tightens the locking handle 409, securing the base 401 firmly to the height slide 304. The design of the locking handle 409 eliminates the need for special tools when installing and adjusting the position of the swing mechanism 400, making the operation simple and quick. During equipment maintenance or replacement of the air gouging torch 500, the operator can quickly loosen the locking handle 409 to remove the entire swing mechanism 400 from the height slide 304 for repair or replacement before reinstallation.

[0056] In addition, the locking handle 409 can also provide an auxiliary locking function during air planing operations. Once the working position of the air planing torch 500 is determined, the locking handle 409 further locks the swing mechanism 400 and the height slide 304, which can prevent positional changes caused by vibration and ensure the positional stability of the air planing torch 500 during operation.

[0057] According to one embodiment provided by the present invention, such as Figure 1 and Figure 5 As shown, the air planer also includes a laser sensor 700, which is located above the air planer torch 500 and is electrically connected to the electrical control cabinet 600.

[0058] In this embodiment, the laser sensor 700 is a non-contact distance measurement sensor that emits a laser beam toward the workpiece surface and receives the reflected light. The distance between the sensor and the workpiece surface is calculated by measuring the time of flight or phase difference of the laser beam. The laser sensor 700 is positioned above the air gouging torch 500, with its detection direction facing the workpiece surface below the air gouging torch 500, i.e., the air gouging operation area. Preferably, the laser sensor 700 is equipped with a clamp 701, which secures it to the upper cantilever of the air gouging torch 500.

[0059] During air gouging, the laser sensor 700 continuously monitors the distance between the air gouging torch 500 and the workpiece surface, transmitting the signal to the control cabinet 600. The controller inside the control cabinet 600 compares the feedback signal from the laser sensor 700 with a preset ideal distance value and calculates the deviation. If the actual distance deviates from the preset value, the controller automatically activates the height adjustment component to fine-tune the vertical position of the air gouging torch 500, ensuring the actual distance remains within the preset range. The introduction of the laser sensor 700 enables automatic control of the distance between the air gouging torch 500 and the workpiece, fundamentally solving the problem of groove depth deviation caused by hand tremors or fatigue during manual operation.

[0060] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
