Description

Technical Field

[0001] This application relates to the field of welding equipment technology, and in particular to welding equipment for the inner ring of oil tankers in oil tank trucks. Background Technology

[0002] A tanker truck is a specialized vehicle used for transporting liquid media. Its core component is a cylindrical or elliptical sealed tank. Inside this tank, there is a ring-shaped structural component called the inner ring. The inner ring is fixed to the inner wall of the tank by welding. The core function of this inner ring is to provide a solid and reliable mounting base for the baffle plate. As a component that directly suppresses the sloshing of liquid inside the tank, the baffle plate itself needs to be fixed to the inner ring by welding, bolting, or fitting. Therefore, the inner ring of the tank essentially constitutes an important part of the internal skeleton structure of the tank, effectively transferring and dispersing the periodic liquid impact load borne by the baffle plate to the entire tank wall.

[0003] In existing technologies, the welding device for the inner ring of an oil tank typically includes a welding actuator, a welding torch moving mechanism, and a control system. The welding actuator often employs automatic submerged arc welding, while the welding torch moving mechanism usually adopts a guide rail or robotic arm structure. The guide rail is fixed to the opening of the oil tank by a bracket, driving the welding torch to perform precise circular movements on the connection points between the inner ring and both sides of the tank wall, ensuring the continuity of the weld. These structures are physically and signal-connected through rigid connectors, drive shafts, and electrical circuits, forming a collaborative whole system with the common goal of achieving high-quality welding of the inner ring inside the oil tank.

[0004] Regarding the aforementioned technologies, existing tank inner ring welding devices require a robotic arm to drive a welding torch to sequentially weld the connection points between the inner ring and the inner wall of the tank on both sides. Sequential welding on both sides may lead to uneven welding stress distribution, and the shrinkage stress caused by heat input cannot be symmetrically balanced, resulting in bending deformation of the inner ring towards the welded side, which in turn seriously affects the perpendicularity of the inner ring to the tank axis. In addition, the existing technology does not perform precise positioning and adjustment between the inner ring and the tank before welding begins, which may increase welding deviation and cause obvious weld formation defects. These defects not only reduce the mechanical strength of the weld but also form stress concentration points in the weld area, reducing the fatigue life of the tanker under long-term cyclic loads. Therefore, improvements are needed. Summary of the Invention

[0005] In order to perform horizontal and vertical adjustments on the oil tank, and to simultaneously weld both sides of the inner ring of the oil tank, this application provides welding equipment for the inner ring of the oil tank of an oil tanker truck.

[0006] The welding equipment for the inner ring of the oil tanker provided in this application adopts the following technical solution: Welding equipment for the inner ring of an oil tanker includes a placement platform on which the oil tank is placed. The platform is equipped with adjustment components for horizontal and vertical adjustment of the oil tank. A work frame is located on one side of the platform, and a movable platform is slidably mounted on the upper end of the work frame. A first drive motor is mounted on the movable platform, and a gear is mounted on the output end of the first drive motor. A geared rail is mounted on the work frame, and the gear meshes with the geared rail. A connecting frame is mounted on the movable platform. During welding of the inner ring, the end of the connecting frame away from the movable platform is located inside the oil tank. A mounting plate is rotatably mounted on the end of the connecting frame away from the movable platform. A clamping and welding mechanism is provided on the side of the mounting plate away from the connecting frame for clamping the inner ring and simultaneously welding both sides of the inner ring.

[0007] By adopting the above technical solution, the oil tank is placed on the placement platform. The adjustment component in this application can adjust the oil tank to a horizontal state and make the center of the oil tank and the center of the mounting plate at the same height. After the adjustment is completed, the first drive motor is started. The output end of the first drive motor rotates to drive the gear to rotate. The gear rotation drives the moving platform to move along the toothed track on the mounting frame into the oil tank. The movement of the moving platform drives the connecting frame and the mounting plate to move. When the mounting plate moves, the clamping and welding mechanism can clamp the inner ring of the oil tank and move it synchronously to the welding point. Then, the clamping and welding mechanism can simultaneously weld both sides of the inner ring of the oil tank. Compared with the welding device in the prior art, the welding accuracy, welding quality and welding efficiency of the inner ring of the oil tank are improved, and the safety and reliability of the oil tank in long-term use are enhanced.

[0008] Optionally, the adjustment assembly includes a mounting base, a first electric telescopic rod, a rotating roller, a second drive motor, a connecting shaft, a laser rangefinder, a mounting frame, and a fixing component. The first electric telescopic rod is horizontally disposed at the upper end of the placement platform. The mounting base is slidably disposed at the upper end of the placement platform and is fixedly connected to the telescopic end of the first electric telescopic rod. The rotating roller is rotatably disposed at the upper end of the mounting base. Four sets of mounting bases, the first electric telescopic rod, and the rotating roller are symmetrically arranged. The four sets of mounting bases, the first electric telescopic rod, and the rotating roller are respectively disposed at the four corners of the upper end of the placement platform. Two sets of second drive motors are provided, each set being mounted on a mounting base away from the work frame, and their output ends being fixedly connected to two sets of rotating rollers away from the work frame. Two sets of connecting shafts are symmetrically provided, with both ends of each set being fixedly connected to one end of each set of rotating rollers on both sides of the oil tank. Two sets of mounting frames are symmetrically provided, each set being located in the middle of the upper part of the placement platform and on both sides of the oil tank. Three sets of laser rangefinders are provided, with two sets of laser rangefinders located on the upper part of the two sets of mounting frames, and the other set of laser rangefinders located in the middle of the upper part of the placement platform. The fixing component is provided on the mounting frame and is used to clamp and fix the oil tank after adjustment.

[0009] By adopting the above technical solution, the oil tank is placed on four sets of rotating rollers. Two sets of second drive motors are simultaneously started. The outputs of these two motors rotate, driving the four sets of rotating rollers and two sets of connecting shafts to rotate. The rotation of the four sets of rotating rollers causes the oil tank to rotate, thus achieving horizontal adjustment of the oil tank. After horizontal adjustment is completed, four sets of first electric telescopic rods are simultaneously started. The movement of these four electric telescopic rods moves the four mounting bases and four sets of rotating rollers. The four sets of rotating rollers, moving closer or further apart along the circular cross-section of the oil tank, can cause the oil tank to rise or fall, thereby achieving horizontal adjustment of the oil tank. The height of the tank is adjusted. After adjustment, the laser rangefinders on the two sets of mounting brackets and the laser rangefinder on the placement platform are activated. The three sets of laser rangefinders emit beams to measure the distance to the tank shell. If the three distances are the same, it indicates that the center of the tank has been adjusted to the specified height. If the distances are not equal, the height of the tank needs to be adjusted again based on the data from the three sets of laser rangefinders. This achieves coaxial dynamic adjustment of the tank and the inner ring of the tank. The adjustment is then checked and confirmed to ensure that the tank and the mounting plate are coaxial, thereby improving the welding accuracy and reducing the impact on the subsequent welding of the inner ring of the tank.

[0010] Optionally, the fixing component includes a second electric telescopic rod and a clamping pad. Two sets of the second electric telescopic rods are symmetrically arranged, and the two sets of the second electric telescopic rods are respectively arranged on the two sets of mounting brackets, with the telescopic ends of both sets located close to the oil tank. The two sets of the second electric telescopic rods are located below the two sets of laser rangefinders. Two sets of the clamping pads are symmetrically arranged, and the two sets of clamping pads are respectively arranged on the telescopic ends of the two sets of the second electric telescopic rods.

[0011] By adopting the above technical solution, after the oil tank is adjusted, two sets of second electric telescopic rods are activated simultaneously. The telescopic ends of the two sets of second electric telescopic rods move, driving the two sets of clamping pads to move towards the oil tank at the same time, thereby clamping the adjusted oil tank and preventing the oil tank from shifting during the subsequent welding process, thus improving the welding accuracy and welding quality.

[0012] Optionally, the clamping and welding mechanism includes a bidirectional cylinder, a first sliding seat, a finger cylinder, rollers, and a welding assembly. The bidirectional cylinder is located at the center of the mounting plate on the side away from the connecting frame. Two sets of first sliding seats are symmetrically arranged, each set slidingly disposed on the side of the mounting plate away from the connecting frame, and fixedly connected to the two telescopic ends of the bidirectional cylinder. Two sets of finger cylinders are symmetrically arranged, each set fixedly disposed on one of the two sets of first sliding seats. Four sets of rollers are symmetrically arranged, each set rotatably disposed on one of the two sets of first sliding seats and located on both sides of the two sets of finger cylinders. The welding assembly is located on the side of the mounting plate away from the connecting frame and is used to simultaneously weld both sides of the inner ring of the oil tank.

[0013] By adopting the above technical solution, the inner ring of the oil tank is placed on four sets of rollers. The bidirectional cylinder is activated, and its two telescopic ends move to both ends, causing the two sets of first sliding seats to move to both ends. This movement of the first sliding seats in turn moves the two sets of finger cylinders and the four sets of rollers to both ends. The movement of the four sets of rollers to both ends causes the inner ring of the oil tank to rise. When the inner ring of the oil tank is coaxial with the mounting plate, the bidirectional cylinder is closed, and the two sets of finger cylinders are activated, thereby achieving stable clamping of the inner ring of the oil tank and keeping it coaxial with the oil tank, thus improving the welding accuracy of the inner ring. When the inner ring of the oil tank moves to the welding point, the two sets of finger cylinders are closed, canceling the... The clamping mechanism of the inner ring of the oil tank, when the mounting plate rotates, drives the bidirectional cylinder and four sets of rollers to rotate synchronously. Since the four sets of rollers continuously press against the inner circumferential wall of the inner ring of the oil tank, the outer circumferential wall of the inner ring of the oil tank can remain pressed against the inner circumferential wall of the oil tank. This ensures that the inner ring of the oil tank does not shift relative to the oil tank during subsequent welding. Furthermore, the outward radial clamping force can automatically compensate for the microscopic deformation of the inner ring caused by heat during the welding process, ensuring that the contact pressure between the inner ring and the tank wall remains stable and uniform. This reduces welding defects such as incomplete fusion and undercut caused by instantaneous stress release or poor contact, improves the density and fatigue strength of the weld, and further enhances welding accuracy and quality.

[0014] Optionally, the welding assembly includes a stepper motor, a drive wheel, a driven wheel, a belt, a third electric telescopic rod, a welding torch, and a second sliding seat. The stepper motor is located at one end of the connecting frame near the mounting plate. The drive wheel is located on the output end of the stepper motor. The driven wheel is located at one end of the mounting plate near the connecting frame and below the drive wheel. The belt is sleeved on the outer peripheral walls of the drive wheel and the driven wheel. The third electric telescopic rod is located at the center of the side of the mounting plate away from the connecting frame and is perpendicular to the bidirectional cylinder. The second sliding seat is slidably located on the side of the mounting plate away from the connecting frame and is fixedly connected to the telescopic end of the third electric telescopic rod. Two sets of welding torches are symmetrically arranged, and both sets of welding torches are slidably located on the second sliding seat.

[0015] By adopting the above technical solution, after the installation plate moves to the welding point, the third electric telescopic rod is activated. The telescopic end of the third electric telescopic rod moves, driving the second sliding seat to move. The movement of the second sliding seat drives the two sets of welding torches to move. After moving to the appropriate position, the two sets of welding torches are activated and the stepper motor is activated simultaneously. The output end of the stepper motor rotates, driving the drive wheel to rotate. The rotation of the drive wheel drives the belt and the driven wheel to rotate. The rotation of the driven wheel drives the installation plate to rotate. The rotation of the installation plate drives the third electric telescopic rod, the second sliding seat, and the two sets of welding torches to rotate, thereby realizing simultaneous welding of both sides of the inner ring of the oil tank, effectively balancing welding stress, reducing workpiece deformation, ensuring the symmetry and strength of the welded structure, and improving welding quality and efficiency.

[0016] Optionally, a first cylinder and a second cylinder are disposed at the center of the side of the mounting plate away from the connecting frame. The first cylinder is located between the bidirectional cylinder and the third electric telescopic rod. The second cylinder and the first cylinder are symmetrically arranged along the length direction of the bidirectional cylinder. A third sliding seat is disposed on the telescopic end of both the first cylinder and the second cylinder. Two sets of pneumatic picks are symmetrically slidably disposed on the third sliding seat on the telescopic end of the first cylinder. Two sets of grinders are symmetrically slidably disposed on the third sliding seat on the telescopic end of the second cylinder.

[0017] By adopting the above technical solution, after welding is completed, the two sets of welding torches are retracted to a safe position using the third electric telescopic rod. Then, the first cylinder is activated, and its telescopic end moves, causing the third sliding seat to move. The movement of the third sliding seat then moves the two sets of pneumatic picks. After they reach the appropriate position, the two sets of pneumatic picks are activated simultaneously. The rotation of the mounting plate causes the two sets of pneumatic picks to rotate, thus simultaneously cleaning the welding slag on both sides of the inner ring of the oil tank. After cleaning, the first cylinder is activated again, and its telescopic end moves, causing the two sets of pneumatic picks to retract to a safe position. Then, the second cylinder is activated, and its telescopic end moves, causing the third sliding seat to move. The sliding seat moves, driving two sets of grinding machines to move. After moving to the appropriate position, the two sets of grinding machines are started simultaneously. The rotating mounting plate drives the two sets of grinding machines to rotate, thereby achieving simultaneous grinding of the welds on both sides of the inner ring of the oil tank. This improves production efficiency and processing continuity. Compared with the prior art where welding slag cleaning and grinding require moving the workpiece to different workstations, this application encloses the pollution source inside a single workpiece, facilitating centralized collection and treatment. Furthermore, since welding slag cleaning and grinding are based on the same precise positioning reference, it reduces the loss of reference caused by workpiece handling and reclamping, thereby reducing welding rework caused by inadequate cleaning and grinding or positional deviation.

[0018] Optionally, a third cylinder is provided at the center of the side of the mounting plate away from the connecting frame. The third cylinder and the first cylinder are symmetrically arranged along the length direction of the third electric telescopic rod. A fourth sliding seat is provided on the telescopic end of the third cylinder, and two sets of spray guns are symmetrically slidably arranged on the fourth sliding seat.

[0019] By adopting the above technical solution, after grinding is completed, the two sets of grinding machines are retracted to a safe position by the second cylinder. Then, the third cylinder is started. The extension end of the third cylinder moves, which drives the fourth sliding seat to move. The movement of the fourth sliding seat drives the two sets of spray guns to move. After moving to the appropriate position, the two sets of spray guns are started simultaneously. The rotation of the mounting plate drives the two sets of spray guns to rotate, thereby realizing the simultaneous spraying of protective layer on the weld seams on both sides of the inner ring of the oil tank, improving the protective performance of the inner ring of the oil tank.

[0020] Optionally, both the second sliding seat and the third sliding seat are provided with bidirectional electric push rods. The two telescopic ends of the bidirectional electric push rod on the second sliding seat are respectively fixedly connected to the two sets of welding guns, and the two telescopic ends of the bidirectional electric push rod on the third sliding seat are respectively fixedly connected to the two sets of pneumatic picks and the two sets of grinders.

[0021] By adopting the above technical solution, the bidirectional electric push rod can adjust the distance between the two sets of welding torches, two sets of pneumatic picks and two sets of grinders according to the actual working conditions, thereby adapting to the inner ring or weld of oil tanks of different widths, enhancing the versatility and processing accuracy of the equipment, and ensuring that all tools can be operated at the optimal working distance.

[0022] Optionally, multiple sets of fourth cylinders are spaced apart on the outer peripheral wall of the connecting frame, and each set of fourth cylinders is provided with a support wheel on its telescopic end.

[0023] By adopting the above technical solution, after the connecting frame stops moving, the fourth cylinder is activated. The extension end of the fourth cylinder moves, driving the support wheel to move until the support wheel abuts against the inner circumferential wall of the oil tank. This provides stable multi-point support for the connecting frame that extends into the oil tank, reducing the shaking and sagging of the connecting frame and mounting plate during operation due to excessive cantilever length. This, in turn, improves the precision and stability of welding, cleaning, grinding, and spraying the inner ring of the oil tank.

[0024] Optionally, each of the four sets of mounting bases is embedded with a pressure sensor for detecting whether the oil tank is in a horizontal state.

[0025] By adopting the above technical solution, after the oil tank is placed on the four sets of rotating rollers, the four sets of pressure sensors detect the pressure value they bear in real time. If the pressure values ​​of the four sets of pressure sensors are consistent, it indicates that the oil tank is in a horizontal state, thereby realizing the verification and confirmation of the horizontal adjustment of the oil tank, and providing a solid foundation for subsequent high-quality welding.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. The adjustment assembly in this application can adjust the oil tank horizontally and vertically. The oil tank is placed on four sets of rotating rollers, and two sets of second drive motors are simultaneously started. The output ends of the two sets of second drive motors rotate, driving the four sets of rotating rollers and two sets of connecting shafts to rotate. The rotation of the four sets of rotating rollers drives the oil tank to rotate, thereby achieving horizontal adjustment of the oil tank. After horizontal adjustment is completed, four sets of first electric telescopic rods are simultaneously started. The movement of the four sets of first electric telescopic rods moves the four sets of mounting seats and the four sets of rotating rollers. The four sets of rotating rollers along the circular cross-section of the oil tank move closer to or further away from each other, causing the oil tank to rise or fall. The height of the oil tank is adjusted by lowering the tank. After adjustment, the laser rangefinders on the two sets of mounting brackets and the laser rangefinder on the placement platform are activated. The three sets of laser rangefinders emit beams to measure the distance to the outer shell of the oil tank. If the three distances are the same, it indicates that the center of the oil tank has been adjusted to the specified height. If the distances are not equal, the height of the oil tank needs to be adjusted again based on the data from the three sets of laser rangefinders. This achieves coaxial dynamic adjustment of the oil tank and the inner ring of the oil tank. The adjustment is then checked and confirmed to ensure that the oil tank and the mounting plate are coaxial, thereby improving the welding accuracy and reducing the impact on the subsequent welding of the inner ring of the oil tank. 2. The clamping and welding mechanism in this application can stably clamp the inner ring of the oil tank and keep it coaxial with the oil tank. The inner ring is placed on four sets of rollers. The bidirectional cylinder is activated, and its two telescopic ends move to both ends, causing the two sets of first sliding seats to move to both ends. The movement of the two sets of first sliding seats to both ends causes the two sets of finger cylinders and the four sets of rollers to move to both ends. The movement of the four sets of rollers to both ends causes the inner ring of the oil tank to rise. When the inner ring of the oil tank is coaxial with the mounting plate, the bidirectional cylinder is closed, and the two sets of finger cylinders are activated, thereby achieving stable clamping of the inner ring of the oil tank and keeping it coaxial with the oil tank, thus improving the welding accuracy of the inner ring of the oil tank. When the inner ring of the oil tank moves to the welding point... When the two sets of finger cylinders are closed, the clamping of the inner ring of the oil tank is released. When the installation plate rotates, it can drive the bidirectional cylinder and four sets of rollers to rotate synchronously. Since the four sets of rollers are continuously pressed against the inner circumferential wall of the inner ring of the oil tank, the outer circumferential wall of the inner ring of the oil tank can be pressed against the inner circumferential wall of the oil tank. This ensures that the inner ring of the oil tank will not be relatively offset from the oil tank during subsequent welding. Moreover, the outward radial clamping force can automatically compensate for the micro-deformation of the inner ring caused by heat during the welding process. This ensures that the contact pressure between the inner ring and the tank wall is always stable and uniform, reducing welding defects such as incomplete fusion and undercut caused by instantaneous stress release or poor contact. This improves the density and fatigue strength of the weld, thereby further improving the welding accuracy and welding quality. 3. The welding assembly in this application can simultaneously weld both sides of the inner ring of the oil tank. When the mounting plate moves to the welding position, the third electric telescopic rod is activated. The telescopic end of the third electric telescopic rod moves, driving the second sliding seat to move. The movement of the second sliding seat drives the two sets of welding torches to move. After moving to the appropriate position, the two sets of welding torches are activated and the stepper motor is activated simultaneously. The output end of the stepper motor rotates, driving the drive wheel to rotate. The rotation of the drive wheel drives the belt and the driven wheel to rotate. The rotation of the driven wheel drives the mounting plate to rotate. The rotation of the mounting plate drives the third electric telescopic rod, the second sliding seat, and the two sets of welding torches to rotate, thereby realizing simultaneous welding of both sides of the inner ring of the oil tank, effectively balancing welding stress, reducing workpiece deformation, ensuring the symmetry and strength of the welded structure, and improving welding quality and efficiency. 4. The fourth cylinder and support wheel in this application can keep the connecting frame and mounting plate stable. When the fourth cylinder is activated, the extension end of the fourth cylinder moves, driving the support wheel to move until the support wheel abuts against the inner circumferential wall of the oil tank. This provides stable multi-point support for the connecting frame that extends into the oil tank, reducing the shaking and sagging of the connecting frame and mounting plate caused by excessive cantilever length during operation, thereby improving the precision and stability of welding, cleaning, grinding and spraying of the inner ring of the oil tank.

Detailed Implementation

[0030] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0031] This application discloses welding equipment for the inner ring of an oil tanker truck, referring to... Figure 1 , Figure 2 and Figure 3The welding equipment for the inner ring of the oil tanker includes a placement platform 1, on which the oil tanker is placed. An adjustment component 2 is installed on the placement platform 1. A work frame 3 is fixedly installed on one side of the placement platform 1.

A connecting frame 35 is welded to the movable platform 31. When welding the inner ring of the oil tanker, the end of the connecting frame 35 away from the movable platform 31 is located inside the oil tank. An installation plate 36 is rotatably installed on the end of the connecting frame 35 away from the movable platform 31. A clamping welding mechanism 4 is installed on the side of the installation plate 36 away from the connecting frame 35.

[0032] The oil tank is placed on the placement platform 1. The adjustment component 2 in this embodiment can adjust the oil tank to a horizontal state and make the center of the oil tank and the center of the mounting plate 36 at the same height. After the adjustment is completed, the first drive motor 32 is started. The output end of the first drive motor 32 rotates and drives the gear 33 to rotate. The rotation of the gear 33 drives the moving platform 31 to move along the toothed rail 34 on the mounting frame 27 into the oil tank. The movement of the moving platform 31 drives the connecting frame 35 and the mounting plate 36 to move. When the mounting plate 36 moves, the clamping welding mechanism 4 can clamp the inner ring of the oil tank and move it synchronously to the welding point. Then, the clamping welding mechanism 4 welds both sides of the inner ring of the oil tank at the same time. Compared with the welding device in the prior art, the welding accuracy, welding quality and welding efficiency of the inner ring of the oil tank are improved, and the safety and reliability of the oil tank in long-term use are improved. In this embodiment, a tank inner ring conveying device is provided on one side of the work frame 3. The conveying device can convey the tank inner ring to the space between the work frame 3 and the placement platform 1. When conveyed to the space between the work frame 3 and the placement platform 1, the connecting frame 35 moves to drive the clamping and welding mechanism 4 on the mounting plate 36 to move. The clamping and welding mechanism 4 stably clamps the tank inner ring, thereby realizing automated welding of the tank inner ring, improving welding efficiency, and reducing labor costs and the risks of manual operation.

[0033] Reference Figure 1 and Figure 2In order to adjust the level and height of the oil tank, the adjustment component 2 in this embodiment includes a mounting base 21, a first electric telescopic rod 22, a rotating roller 23, a second drive motor 24, a connecting shaft 25, a laser rangefinder 26, a mounting frame 27, and a fixing component. The first electric telescopic rod 22 is horizontally bolted to the upper end of the placement platform 1. The mounting base 21 is slidably mounted to the upper end of the placement platform 1 and is fixedly connected to the telescopic end of the first electric telescopic rod 22. The rotating roller 23 is rotatably mounted to the upper end of the mounting base 21. Four sets of mounting base 21, first electric telescopic rod 22, and rotating roller 23 are symmetrically arranged. The four sets of mounting base 21, first electric telescopic rod 22, and rotating roller 23 are respectively installed at the four corners of the upper end of the placement platform 1. Two sets of second drive motors 24 are provided. The two sets of second drive motors 24 are bolted to two sets of mounting seats 21 away from the work frame 3, and the output ends are fixedly connected to two sets of rotating rollers 23 away from the work frame 3. Two sets of connecting shafts 25 are symmetrically provided. The two ends of the two sets of connecting shafts 25 are fixedly connected to the ends of the two sets of rotating rollers 23 on both sides of the oil tank. Two sets of mounting frames 27 are symmetrically provided. Both sets of mounting frames 27 are bolted to the middle of the upper end of the placement platform 1 and located on both sides of the oil tank. Three sets of laser rangefinders 26 are provided. Two sets of laser rangefinders 26 are bolted to the upper end of the two sets of mounting frames 27, and the other set of laser rangefinders 26 is bolted to the middle of the upper end of the placement platform 1. The fixing parts are installed on the mounting frames 27.

[0034] The oil tank is placed on four sets of rotating rollers 23. Two sets of second drive motors 24 are simultaneously started. The outputs of the two sets of second drive motors 24 rotate, driving the four sets of rotating rollers 23 and the two sets of connecting shafts 25 to rotate. The rotation of the four sets of rotating rollers 23 drives the oil tank to rotate, thus achieving horizontal adjustment of the oil tank. After horizontal adjustment is completed, four sets of first electric telescopic rods 22 are simultaneously started. The movement of the four sets of first electric telescopic rods 22 drives the movement of the four sets of mounting seats 21 and the four sets of rotating rollers 23. The four sets of rotating rollers 23, along the circular cross-section direction of the oil tank, move closer or further apart, causing the oil tank to rise or fall, thereby achieving horizontal adjustment of the oil tank. The height of the tank is adjusted. After adjustment, the laser rangefinders 26 on the two sets of mounting brackets 27 and the laser rangefinders 26 on the placement platform 1 are activated. The three sets of laser rangefinders 26 emit beams to measure the distance to the outer shell of the oil tank. If the three distances are the same, it indicates that the center of the oil tank has been adjusted to the specified height. If the distances are not equal, the height of the oil tank needs to be adjusted again based on the data of the three sets of laser rangefinders 26. This achieves coaxial dynamic adjustment of the oil tank and the inner ring of the oil tank. The adjustment is then checked and confirmed to ensure that the oil tank and the mounting plate are coaxial, thereby improving the welding accuracy and reducing the impact on the subsequent welding of the inner ring of the oil tank.

[0035] Reference Figure 1 and Figure 2After the oil tank is adjusted, it needs to be fixed to prevent displacement during the subsequent welding process. Therefore, the fixing components in this embodiment include a second electric telescopic rod 28 and a clamping pad 29. Two sets of second electric telescopic rods 28 are symmetrically arranged. The two sets of second electric telescopic rods 28 are bolted to two sets of mounting brackets 27, and the telescopic ends are close to the oil tank. The two sets of second electric telescopic rods 28 are located below the two sets of laser rangefinders 26. Two sets of clamping pads 29 are symmetrically arranged. The two sets of clamping pads 29 are fixedly installed on the telescopic ends of the two sets of second electric telescopic rods 28.

[0036] After the oil tank is adjusted, two sets of second electric telescopic rods 28 are activated simultaneously. The telescopic ends of the two sets of second electric telescopic rods 28 move, causing the two sets of clamping pads 29 to move towards the oil tank at the same time, thereby clamping the adjusted oil tank and preventing the oil tank from shifting during the subsequent welding process, thus improving the welding accuracy and welding quality. In this embodiment, the clamping pads 29 are made of nitrile rubber, which is a preferred material in this embodiment. It can also be made of polyurethane or other materials.

[0037] Reference Figure 2 and Figure 4 To clamp the inner ring of the oil tank and prevent it from shifting during welding, the clamping and welding mechanism 4 in this embodiment includes a bidirectional cylinder 41, a first sliding seat 42, a finger cylinder 43, rollers 44, and a welding assembly 5. The bidirectional cylinder 41 is bolted to the center of the mounting plate 36 away from the connecting frame 35. Two sets of first sliding seats 42 are symmetrically arranged, and both sets of first sliding seats 42 are slidably mounted on the side of the mounting plate 36 away from the connecting frame 35, and are respectively fixedly connected to the two telescopic ends of the bidirectional cylinder 41. Two sets of finger cylinders 43 are symmetrically arranged, and the two sets of finger cylinders 43 are respectively fixedly mounted on the two sets of first sliding seats 42. Four sets of rollers 44 are symmetrically arranged, and the four sets of rollers 44 are rotatably mounted on the two sets of first sliding seats 42 and located on both sides of the two sets of finger cylinders 43. The welding assembly 5 is mounted on the side of the mounting plate 36 away from the connecting frame 35.

[0038] The inner ring of the oil tank is placed on four sets of rollers 44. The bidirectional cylinder 41 is activated, causing its two telescopic ends to move towards both ends, which in turn moves the two sets of first sliding seats 42 towards both ends. This movement of the first sliding seats 42 then moves the two sets of finger cylinders 43 and the four sets of rollers 44 towards both ends. The movement of the four sets of rollers 44 towards both ends causes the inner ring of the oil tank to rise. When the inner ring of the oil tank is coaxial with the mounting plate 36, the bidirectional cylinder 41 is closed, and the two sets of finger cylinders 43 are activated, thus achieving stable clamping of the inner ring of the oil tank and keeping it coaxial with the oil tank, thereby improving the welding accuracy of the inner ring. When the inner ring of the oil tank moves to the welding point, the two sets of finger cylinders 43 are closed, and the inner ring is removed. The clamping of the inner ring of the oil tank is eliminated. When the mounting plate 36 rotates, it can drive the bidirectional cylinder 41 and four sets of rollers 44 to rotate synchronously. Since the four sets of rollers 44 continuously press against the inner circumferential wall of the inner ring of the oil tank, the outer circumferential wall of the inner ring of the oil tank can remain pressed against the inner circumferential wall of the oil tank. This ensures that the inner ring of the oil tank does not shift relative to the oil tank during subsequent welding. Moreover, the outward radial clamping force can automatically compensate for the micro-deformation of the inner ring caused by heat during the welding process. This ensures that the contact pressure between the inner ring and the tank wall is always stable and uniform, reducing welding defects such as incomplete fusion and undercut caused by instantaneous stress release or poor contact. This improves the density and fatigue strength of the weld, thereby further improving the welding accuracy and welding quality.

[0039] Reference Figure 2 and Figure 4 Compared to the prior art of sequentially welding both sides of the inner ring of the oil tank, the welding assembly 5 in this embodiment can simultaneously weld both sides of the inner ring of the oil tank. It includes a stepper motor 51, a drive wheel 52, a driven wheel 53, a belt 54, a third electric telescopic rod 55, a welding torch 56, and a second sliding seat 57. The stepper motor 51 is bolted to one end of the connecting frame 35 near the mounting plate 36. The drive wheel 52 is welded to the output end of the stepper motor 51, and the driven wheel 53 is welded to the mounting plate 36 near the connecting frame. One end of 35 is located below the drive wheel 52. The belt 54 is sleeved on the outer peripheral wall of the drive wheel 52 and the driven wheel 53. The third electric telescopic rod 55 is bolted to the center of the side of the mounting plate 36 away from the connecting frame 35 and is perpendicular to the bidirectional cylinder 41. The second sliding seat 57 is slidably mounted on the side of the mounting plate 36 away from the connecting frame 35 and is fixedly connected to the telescopic end of the third electric telescopic rod 55. Two sets of welding torches 56 are symmetrically arranged, and both sets of welding torches 56 are slidably mounted on the second sliding seat 57.

[0040] After the mounting plate 36 moves to the welding position, the third electric telescopic rod 55 is activated. The telescopic end of the third electric telescopic rod 55 moves, causing the second sliding seat 57 to move. The movement of the second sliding seat 57 causes the two sets of welding torches 56 to move. After moving to the appropriate position, the two sets of welding torches 56 are activated, and the stepper motor 51 is activated simultaneously. The output end of the stepper motor 51 rotates, causing the drive wheel 52 to rotate. The rotation of the drive wheel 52 causes the belt 54 and the driven wheel 53 to rotate. The rotation of the driven wheel 53 causes the mounting plate 36 to rotate. The rotation of the mounting plate 36 causes... The third electric telescopic rod 55, the second sliding seat 57, and the two sets of welding torches 56 rotate to simultaneously weld both sides of the inner ring of the oil tank, effectively balancing welding stress, reducing workpiece deformation, ensuring the symmetry and strength of the welded structure, and improving welding quality and efficiency. In this embodiment, the third electric telescopic rod 55 and the second sliding seat 57 are symmetrically arranged in two sets, and the welding torches 56 are symmetrically arranged in four sets. The two sets of third electric telescopic rods 55 and the second sliding seat 57, as well as the four sets of welding torches 56, can further improve the welding efficiency of the inner ring of the oil tank.

[0041] Reference Figure 4 In order to clean the welding slag on the inner ring of the oil tank and to grind the weld, in this embodiment, a first cylinder 6 and a second cylinder 61 are bolted to the center of the mounting plate 36 away from the connecting frame 35. The first cylinder 6 is located between the bidirectional cylinder 41 and the third electric telescopic rod 55. The second cylinder 61 and the first cylinder 6 are symmetrically arranged along the length direction of the bidirectional cylinder 41. A third sliding seat 62 is fixedly installed on the telescopic ends of both the first cylinder 6 and the second cylinder 61. Two sets of pneumatic picks 63 are symmetrically slidably installed on the third sliding seat 62 on the telescopic end of the first cylinder 6. Two sets of grinders 64 are symmetrically slidably installed on the third sliding seat 62 on the telescopic end of the second cylinder 61.

[0042] After welding is completed, the two sets of welding torches 56 are retracted to a safe position using the third electric telescopic rod 55. Then, the first cylinder 6 is activated, and the telescopic end of the first cylinder 6 moves, causing the third sliding seat 62 to move. The movement of the third sliding seat 62 causes the two sets of pneumatic picks 63 to move. After moving to the appropriate position, the two sets of pneumatic picks 63 are activated simultaneously. The rotation of the mounting plate 36 causes the two sets of pneumatic picks 63 to rotate, thereby simultaneously cleaning the welding slag on both sides of the inner ring of the oil tank. After cleaning is completed, the first cylinder 6 is activated, and the telescopic end of the first cylinder 6 moves the two sets of pneumatic picks 63 to a safe position. Then, the second cylinder 61 is activated, and the telescopic end of the second cylinder 61 moves, causing the third sliding seat 62 to move. The third sliding seat 62 moves, driving the two sets of grinding machines 64 to move. After moving to the appropriate position, the two sets of grinding machines 64 are started simultaneously. The installation plate 36 rotates, driving the two sets of grinding machines 64 to rotate, thereby realizing the simultaneous grinding of the weld seams on both sides of the inner ring of the oil tank. This improves production efficiency and processing continuity. Compared with the prior art, where welding slag cleaning and grinding require moving the workpiece to different workstations, this embodiment of the application encloses the pollution source inside a single workpiece, which is convenient for centralized collection and treatment. Moreover, since welding slag cleaning and grinding are based on the same precise positioning reference, the loss of reference caused by workpiece handling and reclamping is reduced, thereby reducing welding rework caused by inadequate cleaning and grinding or positional deviation.

[0043] In this embodiment, the first cylinder 6 and the third sliding seat 62 on the telescopic end of the first cylinder 6 are symmetrically arranged in two sets, and the pneumatic picks 63 are symmetrically arranged in four sets. The two sets of cylinders and the third sliding seat 62, together with the four sets of pneumatic picks 63, can efficiently remove welding slag and counteract the reaction force. While improving cleaning efficiency and consistency, it effectively suppresses the influence of tool vibration on positioning accuracy and ensures the stability of the oil tank and the inner ring of the oil tank.

[0044] Reference Figure 4 In this embodiment, a third cylinder 7 is bolted to the center of the mounting plate 36 away from the connecting frame 35. The third cylinder 7 and the first cylinder 6 are symmetrically arranged along the length direction of the third electric telescopic rod 55. A fourth sliding seat 71 is fixedly installed on the telescopic end of the third cylinder 7. Two sets of spray guns 72 are symmetrically slidably installed on the fourth sliding seat 71.

[0045] After grinding is completed, the two sets of grinding machines 64 are retracted to a safe position by the second cylinder 61. Then the third cylinder 7 is started. The extension end of the third cylinder 7 moves, which drives the fourth sliding seat 71 to move. The movement of the fourth sliding seat 71 drives the two sets of spray guns 72 to move. After moving to the appropriate position, the two sets of spray guns 72 are started simultaneously. The installation plate 36 rotates, which drives the two sets of spray guns 72 to rotate, thereby realizing the simultaneous spraying of protective layer on the weld seams on both sides of the inner ring of the oil tank, improving the protective performance of the inner ring of the oil tank.

[0046] Reference Figure 2 and Figure 4When performing welding, slag cleaning, and weld grinding, it may be necessary to adjust the distance between the two sets of welding torches 56, the two sets of pneumatic picks 63, and the two sets of grinders 64. Therefore, in this embodiment, the second sliding seat 57 and the third sliding seat 62 are bolted with bidirectional electric push rods 8. The two telescopic ends of the bidirectional electric push rods 8 on the second sliding seat 57 are fixedly connected to the two sets of welding torches 56, and the two telescopic ends of the bidirectional electric push rods 8 on the third sliding seat 62 are fixedly connected to the two sets of pneumatic picks 63 and the two sets of grinders 64, respectively. The bidirectional electric push rods 8 enable the two sets of welding torches 56, the two sets of pneumatic picks 63, and the two sets of grinders 64 to adapt to the inner rings or welds of oil tanks of different widths, thereby enhancing the versatility and processing accuracy of the equipment and ensuring that all tools can be operated at the optimal working distance.

[0047] Reference Figure 2 To prevent the connecting frame 35 and the mounting plate 36 from shaking during operation, multiple sets of fourth cylinders 9 are installed on the outer peripheral wall of the connecting frame 35 in this embodiment of the application at intervals with bolts. Each set of fourth cylinders 9 has a support wheel 91 rotatably mounted on its telescopic end. When the connecting frame 35 stops moving, the fourth cylinder 9 is activated. The telescopic end of the fourth cylinder 9 moves, driving the support wheel 91 to move until the support wheel 91 abuts against the inner peripheral wall of the oil tank. This provides stable multi-point support for the connecting frame 35 that extends into the oil tank, reducing the shaking and sagging of the connecting frame 35 and the mounting plate 36 during operation due to excessive cantilever length. This, in turn, improves the precision and stability of welding, cleaning, grinding, and spraying the inner ring of the oil tank.

[0048] Reference Figure 2 In this embodiment, pressure sensors 211 are embedded in all four sets of mounting bases 21. When the oil tank is placed on the four sets of rotating rollers 23, the four sets of pressure sensors 211 detect the pressure value they bear in real time. If the pressure values ​​of the four sets of pressure sensors 211 are consistent, it indicates that the oil tank is in a horizontal state, thereby realizing the verification and confirmation of the horizontal adjustment of the oil tank, and providing a solid foundation for subsequent high-quality welding.

[0049] The implementation principle of the welding equipment for the inner ring of the oil tanker in this embodiment of the application is as follows: The oil tank is placed on four sets of rotating rollers 23, and two sets of second drive motors 24 are started simultaneously. The output ends of the two sets of second drive motors 24 rotate, driving the four sets of rotating rollers 23 and two sets of connecting shafts 25 to rotate. The rotation of the four sets of rotating rollers 23 drives the oil tank to rotate, thereby achieving horizontal adjustment of the oil tank. After horizontal adjustment is completed, four sets of first electric telescopic rods 22 are started simultaneously. The movement of the four sets of first electric telescopic rods 22 drives the four sets of mounting bases 21 and four sets of rotating rollers 23 to move. The four sets of rotating rollers 23 along the circular cross-section of the oil tank move closer or further apart, which can drive the oil tank to rise or fall, thereby achieving height adjustment of the oil tank. After adjustment is completed, three sets of laser rangefinders 26 are started. The three sets of laser rangefinders 26 emit beams to measure the distance to the outer shell of the oil tank. If the three distances are the same, it indicates that the center of the oil tank has been adjusted to the specified height, thereby ensuring that the oil tank and the mounting plate 36 are coaxial and improving the welding accuracy. The inner ring of the oil tank is placed on four sets of rollers 44. The bidirectional cylinder 41 is activated, moving it to both ends and causing the two sets of first sliding seats 42, two sets of finger cylinders 43, and four sets of rollers 44 to move to both ends. The movement of the four sets of rollers 44 to both ends causes the inner ring of the oil tank to rise. When the inner ring of the oil tank is coaxial with the mounting plate 36, the bidirectional cylinder 41 is closed, and the two sets of finger cylinders 43 are activated, thus achieving stable clamping of the inner ring of the oil tank and keeping it coaxial with the oil tank. When the inner ring of the oil tank moves to the welding point, the two sets of finger cylinders 43 are closed, releasing the clamping of the inner ring. When the mounting plate 36 rotates, it can... The bidirectional cylinder 41 and four sets of rollers 44 rotate synchronously. Since the four sets of rollers 44 continuously press against the inner circumferential wall of the inner ring of the oil tank, the outer circumferential wall of the inner ring of the oil tank can remain pressed against the inner circumferential wall of the oil tank. This ensures that the inner ring of the oil tank does not shift relative to the oil tank during subsequent welding. The outward radial clamping force can automatically compensate for the micro-deformation of the inner ring caused by heat during the welding process. This ensures that the contact pressure between the inner ring and the tank wall is always stable and uniform, reducing welding defects such as incomplete fusion and undercut caused by instantaneous stress release or poor contact. This improves the density and fatigue strength of the weld, thereby further improving the welding accuracy and welding quality. After the mounting plate 36 moves to the welding position, the third electric telescopic rod 55 is activated. The movement of the third electric telescopic rod 55 drives the second sliding seat 57 and the two sets of welding torches 56 to move. After moving to the appropriate position, the two sets of welding torches 56 are activated and the stepper motor 51 is activated simultaneously. The rotation of the stepper motor 51 drives the drive wheel 52, belt 54 and driven wheel 53 to rotate. The rotation of the driven wheel 53 drives the mounting plate 36, the third electric telescopic rod 55, the second sliding seat 57 and the two sets of welding torches 56 to rotate, thereby realizing simultaneous welding of both sides of the inner ring of the oil tank, effectively balancing welding stress, reducing workpiece deformation, and improving welding quality and efficiency.
