Abstract
Description
Technical Field
[0001] The embodiments of this disclosure relate to the field of welding equipment technology, and more specifically, to a special equipment welding apparatus that is easy to adjust. Background Technology
[0002] A pressure vessel is a sealed device that holds gas or liquid under pressure, and is widely used in industrial production, energy, chemical, and medical fields. The structural design of a pressure vessel must consider both pressure-bearing performance and technological functions. It mainly consists of a cylinder, supports, heads, sealing devices, safety accessories, and connecting pipelines. The cylinder, as the main pressure-bearing component, is usually made of rolled and welded steel plates, and is cylindrical or spherical. The former facilitates material flow and manufacturing, while the latter, due to its uniform stress distribution, is often used in high-pressure conditions. The cylinder is usually horizontally fixed to a support, which can be a vertical support plate welded to the cylinder. In existing technologies, welding the support plate to the cylinder results in low welding efficiency, mainly because cylinders of various specifications have different diameters. When welding with a welding torch, it is impossible to automatically match different cylinders for welding. Therefore, it is necessary to design a welding device that allows the welding torch to travel along different curvatures, thereby improving the efficiency of welding the pressure vessel's cylinder to the support. Utility Model Content
[0003] To overcome the above-mentioned defects, the embodiments of this disclosure provide a special equipment welding device that is easy to adjust, which solves the technical problem in the prior art that the welding device cannot be adapted to welding pressure vessel cylinders and supports of various sizes, resulting in low welding efficiency.

The first rotating member and the second rotating member are both hinged to the adjustment component, and the adjustment component is used to drive the first rotating member and the second rotating member to rotate.
[0011] For example, at least one embodiment of this disclosure provides a special equipment welding apparatus that is easy to adjust, wherein the adjustment assembly includes a first bending adjustment member, a second bending adjustment member, and an adjustment screw:
[0012] The first bending adjustment member is hinged to the first rotating member, and the second bending adjustment member is hinged to the second rotating member, for pushing the first rotating member and the second rotating member to rotate;
[0013] Both the first bending adjustment member and the second bending adjustment member have a first threaded portion, and the adjustment screw has a second threaded portion that mates with the two first threaded portions. One of the first threaded portion and the second threaded portion has an internal thread, and the other has an external thread. The two second threaded portions have opposite thread directions.
[0014] For example, at least one embodiment of this disclosure provides a special equipment welding device that is easy to adjust, wherein the adjusting screw further has a nut portion, which is used to rotate the adjusting screw when it is turned.
[0015] For example, at least one embodiment of this disclosure provides a special equipment welding device that is easy to adjust, wherein the adjusting screw is connected to a rotating rod, and the rotating rod is connected to the middle of the adjusting screw and perpendicular to the adjusting screw.
[0016] For example, at least one embodiment of this disclosure provides a special equipment welding device that is easy to adjust, wherein the first rotating member has a first through hole, the second rotating member has a second through hole, and one end of the curved guide rod passes through the first through hole and the other end passes through the second through hole.
[0017] For example, at least one embodiment of this disclosure provides a special equipment welding apparatus that is easy to adjust, which further includes:
[0018] A first stop and a second stop are respectively disposed at both ends of the curved guide rod to block and prevent the curved guide rod from sliding out of the first through hole and the second through hole.
[0019] For example, at least one embodiment of this disclosure provides an easily adjustable special equipment welding apparatus, wherein the traveling platform includes:
[0020] A platform, on which the welding torch is mounted;
[0021] The traveling wheel is a drive wheel and is rotatably mounted on the platform. The traveling wheel abuts against the curved guide rod.
[0022] For example, at least one embodiment of this disclosure provides a special equipment welding apparatus that is easy to adjust, which further includes:
[0023] An anti-detachment frame, which is slidably mounted on the platform;
[0024] Anti-detachment wheels are rotatably mounted on the anti-detachment frame, and the walking wheels and the anti-detachment wheels are respectively located on both sides of the curved guide rod;
[0025] An elastic element, one end of which acts on the anti-slip frame and the other end of which acts on the platform, provides the force for the anti-slip wheel to abut against the bending guide rod.

The beneficial effects of the embodiments of this disclosure are:
[0027] The relative rotation of the first and second rotating components causes relative displacement at both ends of the connected bending guide rod. Because the bending guide rod is made of a material with elastic deformation capability, it undergoes elastic bending deformation under stress at both ends, thus changing its degree of bending. By controlling the rotation angle of the first and second rotating components, the curvature of the bending guide rod can be adjusted to adapt to cylinders of different diameters.
[0028] The traveling table can slide along the curved trajectory of the curved guide rod. The welding torch is mounted on the traveling table, and as the table slides along the curved guide rod, the welding torch moves accordingly, enabling welding of the joint between the cylinder and the support. By adjusting the sliding speed of the traveling table on the curved guide rod, the welding speed can be controlled to meet different welding process requirements. Attached Figure Description

[0036] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0041] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0042] like Figures 1-5 As shown, it illustrates an adjustable special equipment welding device according to an embodiment of the present disclosure, including a base 100, a first rotating member 201 and a second rotating member 202 both rotatably disposed on the base 100, a bending guide rod 300 with one end connected to the first rotating member 201 and the other end connected to the second rotating member 202, the first rotating member 201 and the second rotating member 202 are used to change the bending degree of the bending guide rod 300 after rotation, a walking platform 400 is slidably disposed on the bending guide rod 300, and a welding torch 500 is disposed on the walking platform 400.
[0043] like Figure 1 As shown, the welding device includes a base 100, a first rotating component 201, a second rotating component 202, a bending guide rod 300, a traveling table 400, and a welding torch 500. It can automatically adjust to adapt to welding cylinders of different diameters, thereby improving welding efficiency and quality, and reducing labor costs and labor intensity.
[0044] The base 100 serves as the fundamental support structure for the entire device. It can be a rectangular frame structure with multiple height-adjustable support feet at the bottom. These support feet have anti-slip rubber pads on their bottoms and can be fine-tuned according to the flatness of the work site to ensure the base 100 remains horizontal and stable. Reinforcing ribs are installed inside the frame of the base 100 to further enhance its overall structural strength, ensuring sufficient stability and load-bearing capacity during operation.
[0045] The first rotating component 201 and the second rotating component 202 are rotatably mounted on the base 100 and can be designed as rods to facilitate being pushed and rotated.
[0046] The bending guide rod 300 has certain deformation characteristics. One end is connected to the first rotating member 201, and the other end is connected to the second rotating member 202. It can change its bending degree according to the rotation of the first rotating member 201 and the second rotating member 202. Both ends of the bending guide rod 300 are machined with connecting parts to the ends of the first rotating member 201 and the second rotating member 202. After the first rotating member 201 and the second rotating member 202 rotate, the bending degree of the bending guide rod 300 can be changed, that is, the curvature of the bending guide rod 300, thereby adapting it to pressure vessels of different diameters.
[0047] The traveling table 400 is designed to move actively along the curved guide rod 300, thus providing a foundation for automated welding. An adjustable welding torch mounting bracket is installed on the upper part of the traveling table 400. The mounting bracket is connected to the traveling table 400 and can adjust the angle and height of the welding torch 500 according to the welding process requirements.
[0048] The welding torch 500 is mounted on the traveling platform 400 and connected to the welding power source via a quick connector, facilitating disassembly for torch replacement or maintenance. The welding torch 500 installed on the special equipment welding device can be selected according to user needs, such as a gas welding torch or an automatic welding torch, and is not limited to an electric welding torch.
[0049] The relative rotation of the first rotating member 201 and the second rotating member 202 causes relative displacement at both ends of the connected bending guide rod 300. Because the bending guide rod 300 is made of a material with elastic deformation capability, it will undergo elastic bending deformation under stress at both ends, thereby changing its degree of bending. By controlling the rotation angle of the first rotating member 201 and the second rotating member 202, the curvature of the bending guide rod 300 can be adjusted to adapt to cylinders of different diameters.
[0050] The traveling table 400 can slide along the bending trajectory of the curved guide rod 300. The welding torch 500 is mounted on the traveling table 400. As the traveling table 400 slides along the curved guide rod 300, the welding torch 500 moves accordingly, enabling welding of the joint between the cylinder and the support. By adjusting the sliding speed of the traveling table 400 on the curved guide rod 300, the welding speed can be controlled to meet different welding process requirements.
[0051] Before welding, the base 100 is first placed in the work area, and the support feet are adjusted to make the base 100 horizontal. Based on the diameter of the cylinder to be welded, the required bending degree of the bending guide rod 300 is initially estimated. Then, the first rotating component 201 and the second rotating component 202 are adjusted to make the bending guide rod 300 reach the estimated bending curvature so that it can match the diameter of the pressure vessel to be welded.
[0052] During welding, the drive mechanism of the traveling platform 400, such as a stepper motor, is activated, causing the platform to slide at a constant speed along the bending trajectory of the curved guide rod 300. The welding torch 500 moves accordingly to weld the joint between the cylinder and the support. During welding, the operator can observe the welding process and fine-tune the welding parameters to ensure welding quality. After completing one revolution of welding, the drive mechanism of the traveling platform 400 is stopped, and the welded cylinder and support assembly is removed.
[0053] If welding cylinders of different diameters is required, repeat the operations of the equipment preparation and installation and commissioning stages, adjust the bending curvature of the bending guide rod 300 and the angle and height of the welding torch 500 to adapt to the new cylinder diameter and welding process requirements, and carry out the next round of welding work.
[0054] With the coordinated action of components such as the base 100, the first rotating component 201, the second rotating component 202, and the bending guide rod 300, the curvature of the bending guide rod 300 can be automatically adjusted to quickly adapt to the cylinders of pressure vessels with different diameters. This eliminates the need for frequent manual adjustments to the welding angle or changes in tooling fixtures, saving welding preparation time. Simultaneously, the traveling table 400 can automatically move along the bending guide rod 300, enabling continuous welding. Compared to manual welding, this significantly increases welding speed, thereby greatly improving overall welding efficiency.
[0055] By adjusting the curvature of the bending guide rod 300, the welding torch 500 can always remain perpendicular to the cylinder surface, ensuring consistent welding angles. The uniform movement of the traveling table 400 ensures stable welding speed, reducing welding defects caused by uneven welding speed. In addition, the selected high-performance welding torch 500 and stable welding power source further guarantee welding quality, improving the strength and aesthetics of the weld.
[0056] Automated welding processes reduce the workload of manual operations. Welders only need to debug the equipment before welding and perform necessary monitoring and parameter fine-tuning during the welding process. They no longer need to hold the welding gun for long periods of time to perform high-intensity welding operations, which effectively reduces the labor intensity of welders and improves the working environment.
[0057] This device can adapt to the welding needs of cylinders of various diameters by simply adjusting the curvature of the bending guide rod 300. It eliminates the need to design and manufacture special welding equipment for different cylinders, thereby enhancing the versatility of the equipment and reducing the equipment procurement and maintenance costs for enterprises.
[0058] In some examples, the special equipment welding device may also include an adjustment assembly to adjust the rotation angle of the first rotating member 201 and the second rotating member 202, thereby changing the curvature of the bending guide rod 300. Optionally, the adjustment assembly may be a linear telescopic mechanism, such as a cylinder or hydraulic cylinder. The two ends of the linear telescopic mechanism may be connected to the first rotating member 201 and the second rotating member 202 respectively. The extension and retraction of the linear telescopic mechanism can drive the first rotating member 201 and the second rotating member 202 to rotate, thereby adjusting the curvature of the bending guide rod 300. The adjustment assembly may also include two or more linear telescopic mechanisms, respectively connecting the first rotating member 201 and the second rotating member 202 to the base 100, thereby adjusting the angles of the first rotating member 201 and the second rotating member 202 respectively. The adjustment assembly may also be a rotation mechanism, such as a motor and gear mechanism, adjusting the angles of the first rotating member 201 and the second rotating member 202 by rotating the motor.
[0059] Optional, such as Figure 3 As shown, the adjustment assembly may include a first bending adjustment member 701, a second bending adjustment member 702, and an adjustment screw 800. The first bending adjustment member 701 is hinged to the first rotating member 201, and the second bending adjustment member 702 is hinged to the second rotating member 202, for pushing the first rotating member 201 and the second rotating member 202 to rotate. Both the first bending adjustment member 701 and the second bending adjustment member 702 are designed as rod-shaped structures, which reduce the overall weight while ensuring sufficient strength, facilitating operation and control. The length of the rod is determined according to the actual equipment space and force transmission requirements to ensure good rigidity.
[0060] One end of the first bending adjustment member 701 is hinged to the side of the first rotating member 201 via a pin. Cotter pins are provided at both ends of the pin to prevent it from falling off during operation. The hinge design allows the first bending adjustment member 701 to rotate flexibly relative to the first rotating member 201 to meet different adjustment needs. Similarly, the second bending adjustment member 702 is hinged to the second rotating member 202 in the same manner.
[0061] In some examples, such as Figure 3As shown, both the first bending adjustment member 701 and the second bending adjustment member 702 have a first threaded portion, which is a threaded hole 7011 or 7021. The two ends of the adjusting screw 800 have second threaded portions, which are respectively a first external thread 801 and a second external thread 802. The first external thread 801 is threadedly connected to the threaded hole 7011 of the first bending adjustment member 701, and the second external thread 802 is threadedly connected to the threaded hole 7021 of the second bending adjustment member 702. The threaded holes 7011 and 7021 on the first bending adjustment member 701 and the second bending adjustment member 702 facilitate connection, ensuring sufficient thread engagement length between the adjusting screw 800 and the bending adjustment member, and guaranteeing the stability of the connection. The axis of the threaded hole is perpendicular to the axis of the bending adjustment member's rod body. This design allows the force applied by the adjusting screw 800 to be effectively transmitted to the bending adjustment member, thereby driving the first rotating member 201 and the second rotating member 202 to rotate.
[0062] The adjusting screw 800 is cylindrical in shape, with a smooth rod in the middle. The length of the adjusting screw 800 is determined based on the overall layout of the equipment and the distance between the first and second bending adjustment parts.
[0063] A circular operating handle can be welded to one end of the adjusting screw 800, allowing the operator to easily rotate the adjusting screw 800. By rotating the handle, the adjusting screw 800 can be controlled to screw in and out of the threaded hole, thereby achieving precise adjustment of the relative position of the first rotating component 201 and the second rotating component 202.
[0064] The adjusting screw 800 is threadedly connected to the first bending adjusting member 701 and the second bending adjusting member 702, linking them together. When the adjusting screw 800 is rotated, due to the transmission action of the thread, the first bending adjusting member 701 and the second bending adjusting member 702 move simultaneously along the axial direction of the adjusting screw 800, thereby synchronously driving the first rotating member 201 and the second rotating member 202 to rotate. This synchronous adjustment method ensures that the bending guide rod 300 is subjected to uniform force at both ends, making its curvature change more stable and precise, and effectively avoiding the problem of twisting or uneven force on the bending guide rod 300 caused by asynchronous adjustment at both ends.
[0065] The first external thread 801 and the second external thread 802 at both ends of the adjusting screw 800 adopt opposite thread directions, that is, one is a left-hand thread and the other is a right-hand thread. This design allows the first bending adjusting member 701 and the second bending adjusting member 702 to move towards or away from each other when the adjusting screw 800 is rotated, thereby efficiently changing the relative angle between the first rotating member 201 and the second rotating member 202 and accurately adjusting the curvature of the bending guide rod 300.
[0066] Since the first external thread 801 and the second external thread 802 have opposite thread directions, when the adjusting screw 800 is rotated, according to the principle of thread transmission, the first bending adjusting member 701, which is threaded to the first external thread 801, and the second bending adjusting member 702, which is threaded to the second external thread 802, will move in opposite directions. This reverse synchronous movement directly causes the first rotating member 201 and the second rotating member 202 to rotate relative to each other, thereby changing the curvature of the bending guide rod 300. With each rotation of the adjusting screw 800, the two bending adjusting members will move a predetermined distance according to the thread pitch, thus changing the curvature of the bending guide rod 300. By utilizing the characteristics of thread transmission and controlling the rotation angle of the adjusting screw 800, the relative position of the first rotating member 201 and the second rotating member 202 can be adjusted. For example, when the adjusting screw 800 rotates one revolution, the first and second bending adjustment components will move a fixed distance axially according to the thread pitch, thereby causing the first rotating component 201 and the second rotating component 202 to produce corresponding minute rotations, thus adjusting the curvature of the bending guide rod 300. This precise fine-tuning function is crucial for adapting to the welding requirements of cylinders with different diameters and can further improve welding quality.
[0067] The threaded connection between the adjusting screw 800 and the bending adjustment component enables synchronous and precise adjustment of the first rotating component 201 and the second rotating component 202. This allows for faster and more accurate adjustment of the curvature of the bending guide rod 300, significantly improving adjustment efficiency. Furthermore, by controlling the rotation of the adjusting screw 800, the curvature can be adjusted, further enhancing adjustment precision and meeting the high-precision adjustment requirements for welding cylinders of different diameters.
[0068] Synchronous adjustment ensures uniform force distribution at both ends of the bending guide rod 300, reducing uneven stress and deformation of components caused by asynchronous adjustment, thereby enhancing the stability of the entire equipment during the adjustment process. This not only helps improve welding quality but also extends the service life of various components and reduces equipment maintenance costs.
[0069] Adjusting the screw 800 by turning the operating handle is simple and easy to understand, and operators can master it without complicated training. Furthermore, the threaded connection structure offers high reliability, preventing loosening or malfunction during equipment operation and ensuring stable operation of the adjustment function.
[0070] In some examples, such as Figure 3As shown, the adjusting screw 800 also has a nut portion 803, which is used to rotate the adjusting screw 800 when turned. The nut portion 803 is located in the middle of the adjusting screw 800, and its shape is hexagonal prism, which is convenient for operation with common wrench tools, such as open-end wrenches and socket wrenches. It can provide a large torque application surface, making it easier for operators to turn the adjusting screw 800 more effectively.
[0071] The hexagonal prism shape of the nut part 803 provides a convenient point of force application for the operator. Through the cooperation of the wrench and the nut part 803, the operator can easily convert manual labor into torque on the adjusting screw 800, causing it to rotate. This design fully utilizes the lever principle; when the operator uses the wrench, the length of the wrench acts as the lever arm, generating a larger torque with a smaller force. This allows for easier turning of the adjusting screw 800, achieving the adjustment of the relative position of the first rotating component 201 and the second rotating component 202, ultimately adjusting the curvature of the bending guide rod 300.
[0072] In some examples, such as Figure 3 As shown, the first rotating component 201 has a first through hole 2011, and the second rotating component 202 has a second through hole 2021. One end of the bent guide rod 300 passes through the first through hole 2011, and the other end passes through the second through hole 2021. The diameters of the first through hole 2011 in the first rotating component 201 and the second through hole 2021 in the second rotating component 202 are adapted to the outer diameters of both ends of the bent guide rod 300. The inner walls of the through holes are polished to reduce the frictional resistance after the bent guide rod 300 passes through, while ensuring a proper fit.
[0073] After the through holes are drilled at both ends, locking nuts are used for fastening. The nuts are threaded to the ends of the bending guide rod 300. When the nuts are tightened, the bending guide rod 300 is tightly fixed to the first rotating component 201 and the second rotating component 202, preventing loosening during rotation adjustment and welding operations. To further enhance the connection stability, an elastic washer can be added between the nut and the rotating component, using the elastic deformation of the washer to compensate for gap changes caused by vibration and other factors.
[0074] The first perforation 2011 and the second perforation 2021 facilitate curvature adjustment. When the first rotating component 201 and the second rotating component 202 are driven to rotate relative to each other, the positional changes of the two ends of the bending guide rod 300, which are fastened through the perforations, can be transmitted to the entire bending guide rod 300, thereby inducing controllable elastic bending deformation. This perforated connection-based structural design allows for better curvature adjustment of the bending guide rod 300 and ensures stable force transmission between the bending guide rod 300 and the rotating component during adjustment, thus ensuring the reliability of the entire device under different curvature states.
[0075] The connection structure between the first perforation 2011, the second perforation 2021, and the bending guide rod 300 further improves welding efficiency. This stable and easily adjustable connection method shortens the adjustment time each time the curvature of the bending guide rod 300 is adjusted, allowing for faster adaptation to cylinders of different diameters and reducing the overall preparation time for welding operations.
[0076] In terms of enhancing equipment versatility, the perforated connection structure provides a reliable guarantee for the flexible adjustment of the curvature of the bending guide rod 300. Regardless of the diameter of the cylinder, this structure allows for quick and precise adjustment of the curvature of the bending guide rod 300, enabling the equipment to adapt to a wider range of cylinder specifications and further expanding its versatility.
[0077] In some examples, such as Figure 3 As shown, a first stop 601 and a second stop 602 can also be added. The first stop 601 and the second stop 602 are respectively disposed at both ends of the bent guide rod 300 to block and prevent the bent guide rod 300 from sliding out of the first through hole 2011 and the second through hole 2021. The first stop 601 and the second stop 602 adopt a disc-shaped structure, and their diameter is larger than the diameter of the first through hole 2011 and the second through hole 2021 to ensure that the bent guide rod 300 can be effectively blocked and prevented from sliding out.
[0078] The first stop 601 and the second stop 602 are fixed at both ends of the bent guide rod 300, forming a firm connection with it. The main function of the first stop 601 and the second stop 602 is to block the bent guide rod 300 from both ends after it is connected to the first rotating member 201 and the second rotating member 202. Since the diameter of the stop is larger than the diameter of the perforation hole, when the bent guide rod 300 is subjected to axial force or tends to slip out of the perforation hole due to vibration or other factors, the stop can prevent this from happening, ensuring that the bent guide rod 300 always remains connected to the first rotating member 201 and the second rotating member 202, maintaining the integrity and stability of the entire device structure.
[0079] The first stop 601 and the second stop 602 not only effectively block the flow, but also withstand forces under various working conditions during long-term operation. Together with the bending guide rod 300, they form a reliable integral structure, ensuring that the bending guide rod 300 will not slip out due to the failure of the stop during operation, thus affecting the normal progress of welding work.
[0080] In some examples, such as Figure 4 , Figure 5As shown, the traveling platform 400 includes a platform body 401, a welding torch 500 mounted on the platform body 401, and traveling wheels 402, which are drive wheels and rotatably mounted on the platform body 401, abutting against the curved guide rod 300. The platform body 401 is generally rectangular in shape, ensuring stable support for the welding torch 500 and providing sufficient space for its installation and operation. The platform body 401 is made of a lightweight material, which helps reduce the overall weight of the traveling platform 400, making it more flexible in its movement on the curved guide rod 300.
[0081] A dedicated welding torch mounting base is provided on the top of the platform 401. The traveling wheels 402 are solid tires made of polyurethane material. Polyurethane material has good wear resistance, elasticity and anti-slip properties, which can make it move stably on the curved guide rod 300 and reduce the impact of slippage or vibration on welding accuracy. The traveling wheels 402 are the drive wheels and are driven by a small DC motor.
[0082] During actual welding, based on the material and thickness of the cylinder to be welded and the welding process requirements, the drive system of the traveling platform 400 is activated. Driven by a DC motor, the traveling wheels 402 begin to move along the curved guide rod 300, causing the platform body 401 and the welding torch 500 mounted on it to move along the trajectory of the curved guide rod 300, welding the joint between the cylinder and the support. During the welding process, the operator can observe the welding progress in real time and fine-tune the speed of the traveling wheels 402 using a speed controller based on the weld formation effect to ensure welding quality.
[0083] In some examples, such as Figure 5 As shown, an anti-detachment frame 901 can also be designed, which is slidably mounted on the platform 401; an anti-detachment wheel 902 is rotatably mounted on the anti-detachment frame 901, with the traveling wheel 402 and the anti-detachment wheel 902 located on opposite sides of the curved guide rod 300; an elastic element 903 acts on the anti-detachment frame 901 at one end and on the platform 401 at the other end, providing force for the anti-detachment wheel 902 to abut against the curved guide rod 300. The anti-detachment frame 901 is made of high-strength metal sheet bent into an overall "U" shape. This shape can effectively wrap around one side of the curved guide rod 300, cooperating with the traveling wheel 402 on the other side to prevent the platform 400 from detaching from the curved guide rod 300. The opening width of the "U" shape is slightly larger than the diameter of the curved guide rod 300, ensuring that the anti-detachment frame 901 can slide smoothly on the curved guide rod 300 while providing sufficient protection. It also ensures stable sliding on the platform 401.
[0084] The anti-detachment wheel 902 is made of rubber, which has good elasticity and friction, allowing it to fit tightly against the curved guide rod 300. Even when the walking platform 400 encounters vibration or changes in the curvature of the curved guide rod 300 during movement, it can maintain stable contact and prevent the walking platform 400 from detaching. The anti-detachment wheel 902 is mounted on the anti-detachment frame 901 via a pivot.
[0085] The elastic element 903 can be a tension spring, which can provide sufficient elasticity to ensure that the anti-slip wheel 902 is tightly pressed against the curved guide rod 300. One end of the elastic element 903 is connected to the mounting base, and the other end is connected to the anti-slip bracket 901. For example, it can be fixed to the anti-slip bracket 901 by welding, ensuring that the tension spring can act stably between the anti-slip bracket 901 and the platform 401, providing a continuous abutment force for the anti-slip wheel 902.
[0086] The anti-detachment bracket 901 slides on the linear guide rail of the platform 401 via a linear slider, allowing it to flexibly adjust its position to follow the shape changes of the curved guide rod 300. Anti-detachment wheels 902 are mounted on the anti-detachment bracket 901, located on either side of the curved guide rod 300 along with the traveling wheels 402, forming a clamping structure. The elastic force provided by the elastic element 903 ensures that the anti-detachment wheels 902 remain firmly pressed against the curved guide rod 300. Working together with the traveling wheels 402, they securely restrain the traveling platform 400 onto the curved guide rod 300, preventing it from detaching during movement due to vibration, centrifugal force, or other external forces, thus ensuring the safety and continuity of the welding operation.
[0087] Due to the presence of the elastic element 903, when the curvature of the bending guide rod 300 changes, the anti-detachment bracket 901 can automatically adjust its position under the action of elastic force, ensuring that the anti-detachment wheel 902 always maintains good contact with the bending guide rod 300. This adaptive adjustment capability ensures that the traveling platform 400 can operate reliably on bending guide rods 300 with different curvatures, adapting to the welding requirements of cylinders of various diameters.
[0088] In some examples, such as Figure 5 As shown, the anti-slip frame 901 has a first side stop 9011 and a second side stop 9012, and the walking wheels 402, the first side stop 9011, the anti-slip wheels 902 and the second side stop 9012 are arranged in a circumferential ring around the curved guide rod 300.
[0089] The first side stop 9011 and the second side stop 9012 are integral with the main body of the anti-slip frame 901, and are formed by bending high-strength metal sheets and further processing. The first side stop 9011 and the second side stop 9012 are the two sides of the "U"-shaped structure of the anti-slip frame 901, and maintain a certain gap with the outer contour of the bent guide rod 300. This ensures that the normal operation of the bent guide rod 300 is not hindered, and also effectively limits its movement during the movement of the traveling platform 400.
[0090] The traveling wheel 402, the first side stop 9011, the anti-detachment wheel 902, and the second side stop 9012 are arranged in a ring around the circumference of the curved guide rod 300. The traveling wheel 402 is located on one side of the curved guide rod 300, opposite the anti-detachment wheel 902, while the first side stop 9011 and the second side stop 9012 are located on the other two sides of the curved guide rod 300, evenly distributed around its circumference. This arrangement makes the force on the traveling platform 400 on the curved guide rod 300 more even. No matter what position the traveling platform 400 is in or what direction the external force is applied, it can remain stable through the synergistic effect of these four parts and is not easy to detach from the curved guide rod 300.
[0091] The first side stop 9011 and the second side stop 9012 further improve the anti-detachment mechanism of the walking platform 400 on the curved guide rod 300. In addition to the clamping effect of the anti-detachment wheel 902 and the walking wheel 402 on both sides of the curved guide rod 300, the side stops limit the walking platform 400 from the other two sides, forming a circumferential protective structure around the curved guide rod 300. This structure effectively prevents large displacement of the walking platform 400 in the horizontal direction. Even in the event of sudden lateral forces or vibrations, the side stops prevent the walking platform 400 from detaching from the curved guide rod 300, greatly improving the safety and stability of the walking platform 400's operation.
[0092] The arrangement of the traveling wheel 402, the first side stop 9011, the anti-detachment wheel 902, and the second side stop 9012 in a circumferential ring around the curved guide rod 300 ensures a more uniform force distribution on the traveling platform 400 during movement. Regardless of the curvature of the curved guide rod 300 or the direction of the external force applied to the traveling platform 400, the four components share the force, reducing the possibility of excessive local stress. This uniform force distribution design helps maintain the stable operation of the traveling platform 400, reduces the risk of component wear and damage due to uneven force distribution, and also improves welding quality, ensuring that the welding torch 500 can move stably along the predetermined trajectory.
