Description

Technical Field

[0001] This invention relates to the field of welding technology, and in particular to an adjustable tank-type circuit breaker housing end face flange ring welding equipment. Background Technology

[0002] Tank-type circuit breakers are core switching equipment in high-voltage or ultra-high-voltage power systems. They are characterized by a grounded metal tank and an internal sulfur hexafluoride gas filling, integrating insulation, arc extinguishing, current carrying, and protection. The main function of tank-type circuit breakers is to control and protect electrical equipment such as transmission lines, capacitor banks, and transformers by breaking and making load currents, overload currents, and short-circuit currents. They are one of the key pieces of equipment in power systems. Welding the flange rings on the end face of the tank-type circuit breaker shell is an essential step in its manufacturing, thus requiring welding equipment.

[0003] For example, in a flange welding device disclosed in Chinese Patent Publication No. CN121339816A, a support column is fixedly installed on the upper side of the workbench away from the first mounting bracket. A fixing frame is fixedly installed on the upper end of the support column, and a third cylinder is fixedly installed on the upper end of the fixing frame. During use, the fixing frame and the support column can provide stable support and fixation for the third cylinder, preventing the third cylinder from shaking and affecting the welding quality. The protruding end of the third cylinder passes through the fixing frame and is fixedly installed with a welding head mounting component. A welding head is fixedly installed at the lower end of the welding head mounting component. During use, when the flange is moved directly under the welding head, the third cylinder is activated, and the third cylinder will drive the welding head to move downward to weld the flange.

[0004] In existing technical references, welding can be performed using an electric welding head flange. However, this design has drawbacks for some tank-type components with larger inner diameters. Due to the weight of the tank-type components themselves, it is inconvenient to move them and there are defects in the circumferential welding of the tank-type components. At the same time, it is not convenient to adapt to flange rings with different outer diameters. Summary of the Invention

[0005] To solve the above technical problems, the present invention is implemented through the following technical solution: An adjustable tank-type circuit breaker housing end face flange ring welding equipment includes: a machine body, and a bracket fixedly mounted on the top of the machine body, wherein a ball bearing is rotatably installed on the arc-shaped concave surface at the top of the bracket; A welding mechanism, comprising an auxiliary component and a welding gun, wherein the auxiliary component is mounted on the side of the top of the machine body and the welding gun is mounted on top of the auxiliary component; The adjustment mechanism includes a lifting worktable and a rotating table. The lifting worktable is fixedly installed on the top of the machine body near the bracket. The rotating table is fixedly installed on the top of the lifting worktable. A bracket is fixedly connected to the top of the rotating table. A conical roller is rolled on the top of the bracket. A servo motor is fixedly installed on the surface of the bracket. A linear groove is formed on the conical surface of the outer side of the conical roller. The rotating table drives the conical roller to rotate, so that the conical heads of the two symmetrical conical rollers face each other. The conical surfaces of the two symmetrical conical rollers form a V-shaped opening. The outer circular surface of the tank-type circuit breaker housing fits against the conical surface of the conical roller. The output end of the servo motor drives the conical roller to rotate, so that the spiral linear groove is always in contact with the outer circular surface of the tank-type circuit breaker housing, which can increase the friction and thus transport the tank-type circuit breaker housing. This allows the tank-type circuit breaker housing to move as a whole, and the position of the tank-type circuit breaker housing can be finely adjusted to facilitate the docking of the end of the tank-type circuit breaker housing with the flange ring. A flange ring feeding mechanism includes a mover and a ring frame. The mover is installed on the side of the top of the machine body, and the ring frame is installed on top of the mover. A cylinder is rotatably installed inside the ring frame, and a telescopic device is installed on the outer side of the cylinder. A clamping head is fixedly connected to the telescopic end of the telescopic device. A groove is opened at the corner of the inner side of the clamping head. A pressing assembly is installed on the top of the ring frame. The edge of the flange ring is embedded in the groove, so that the inner side of the clamping head is fully in contact with the surface of the flange ring, limiting the flange ring. By extending the telescopic end of the telescopic device, three evenly distributed clamping heads move towards the center of the cylinder, which can self-center and clamp the flange ring, preventing the flange ring from shifting or tilting. At the same time, by moving the clamping heads inward, it can accommodate flange rings of the same diameter, with strong adaptability.

[0006] Furthermore, there are two brackets, and the two brackets are symmetrically installed along the lifting worktable, with the balls evenly distributed on the arc-shaped concave surface at the top of the bracket.

[0007] Furthermore, the auxiliary components include a flue gas processor and a rotating support base. The flue gas processor is fixedly installed on the side of the top of the machine body, and the rotating support base is fixedly installed on the top of the machine body near the flue gas processor. A welding host is fixedly installed on the top of the flue gas processor. A mechanical arm is installed on the top of the rotating support base, and a mechanical arm is installed on the end of the mechanical arm away from the rotating support base. The welding torch is installed on the top of the mechanical arm, and a conical bucket is fixedly connected to the top of the welding torch. A gas pipe connects the conical bucket and the flue gas processor. By rotating the rotating support base, the mechanical arm can be rotated to adjust its position. The mechanical arm will also rotate and adjust its position along with the mechanical arm. Under the linkage of the mechanical arm and the mechanical arm, the position of the welding torch is adjusted, which helps to align the welding torch with the weld seam between the end face of the tank-type circuit breaker housing and the flange ring, thereby promoting accurate welding.

[0008] Furthermore, the welding gun is installed at an angle, and the welding gun is electrically connected to the welding host via a wire.

[0009] The fan inside the flue gas processor draws in the fumes, which are then connected to the air duct. This allows the conical hopper to absorb the fumes generated during welding. The air duct then transports the fumes to the flue gas processor for timely treatment, reducing the spread of toxic and harmful gases.

[0010] Furthermore, the air pipe is curved and connects the flue gas processor to the conical hopper.

[0011] Furthermore, there are two rotary tables, and the two rotary tables are symmetrically installed along the central axis in the middle of the lifting worktable, with the conical rollers installed directly above the rotary tables.

[0012] Furthermore, the central shaft of the conical roller is fixedly installed to the output end of the servo motor via a coupling, and the linear groove is spiral-shaped and evenly distributed on the conical surface on the outer side of the conical roller.

[0013] Furthermore, the axis of the cylinder coincides with the center of the annular frame, and the clamping head is installed at the port inside the cylinder.

[0014] Furthermore, the mover includes a linear guide rail, which is fixedly installed on the side of the top of the machine body. A gantry frame is mounted on the top of the linear guide rail. A stepper motor is fixedly installed on the side of the surface of the gantry frame. The output end of the stepper motor is meshed with the surface of the linear guide rail via a gear and rack. A linear driver is fixedly installed on the top of the inner cavity of the gantry frame. The telescopic end of the linear driver is fixedly installed on the side of the surface of the ring frame. By extending the telescopic end of the linear driver, the ring frame and the cylinder can be pushed upward, thereby adjusting the height of the flange ring. By extending the cylinder's telescopic end and connecting it with the connecting plate, the clamping component moves downward, and the cylindrical wheel moves downward along with the clamping component. The cylindrical wheel fits against the top of the outer circular surface of the tank-type circuit breaker housing, and the cylindrical wheel rolls and presses against the tank-type circuit breaker housing. The ring frame provides rotational support for the cylinder, so that when the end face of the tank-type circuit breaker housing is circumferentially welded, the flange ring will rotate circumferentially with the tank-type circuit breaker housing, making it less likely for the structure to jam.

[0015] Furthermore, the pressing assembly includes a cylinder, which is fixedly installed on the top of the ring frame. A connecting plate is fixedly installed on the telescopic end of the cylinder. A clamping member is fixedly connected to the bottom of the connecting plate and the end away from the cylinder. A cylindrical wheel is rolled on the inner side of the clamping member.

[0016] The beneficial effects of the technical solution provided by this invention include: 1. The rotation of the rotating support base drives the mechanical arm to rotate, adjusting its position. The mechanical arm rotates and adjusts its position along with the mechanical arm. The linkage between the mechanical arm and the mechanical arm adjusts the position of the welding gun, helping to align the welding gun with the weld seam between the end face of the tank circuit breaker housing and the flange ring, thus promoting accurate welding.

[0017] Second, the fan in the flue gas processor draws in the flue gas, and the air pipe connects to the suction, so that the conical bucket absorbs the flue gas generated during the welding process of the welding gun. The air pipe then transports the flue gas to the flue gas processor for timely treatment, reducing the spread of toxic and harmful gases.

[0018] 3. A V-shaped opening is formed by two symmetrical conical rollers. The outer circular surface of the tank-type circuit breaker housing is in contact with the conical surface of the rollers. The output of a servo motor drives the rollers to rotate, so that the spiral linear groove is always in contact with the outer circular surface of the tank-type circuit breaker housing. This increases the friction and allows the tank-type circuit breaker housing to be transported, enabling the overall movement of the tank-type circuit breaker housing. The position of the tank-type circuit breaker housing can be finely adjusted to facilitate the docking of the end of the tank-type circuit breaker housing with the flange ring.

[0019] Fourth, by utilizing the outer circular surface of the conical roller to fit against the outer circular surface of the tank-type circuit breaker housing, the conical roller is driven to roll through the output end of the servo motor. Since the two opposing conical rollers roll in the same direction, the tank-type circuit breaker housing can be rotated, which facilitates circumferential welding of the tank-type circuit breaker housing. Multiple functions can be achieved by utilizing the continuous state of the conical roller.

[0020] 5. Place the flange ring to be welded into the clamping head position inside the cylinder, with the edge of the flange ring embedded in the groove, so that the inner side of the clamping head is fully in contact with the surface of the flange ring, limiting the flange ring. By using the extension of the telescopic end of the expansion joint, the three evenly distributed clamping heads move towards the center of the cylinder, which can self-center and clamp the flange ring, preventing the flange ring from shifting or tilting. At the same time, by moving the clamping heads inward, it can accommodate flange rings of the same diameter, with strong adaptability.

[0021] VI. By extending the telescopic end of the linear actuator, the ring frame and cylinder can be pushed upwards, thereby adjusting the height of the flange ring. By extending the telescopic end of the cylinder, the clamping component moves downwards, and the cylindrical wheel moves downwards along with the clamping component. The cylindrical wheel fits against the top of the outer circular surface of the tank-type circuit breaker housing, and the cylindrical wheel rolls and presses against the tank-type circuit breaker housing. The ring frame provides rotational support for the cylinder, so that when the end face of the tank-type circuit breaker housing is circumferentially welded, the flange ring will rotate circumferentially with the tank-type circuit breaker housing, making it less likely for the structure to jam.

[0024] Example 1, see Figures 1-4 A technical solution is provided: An adjustable tank-type circuit breaker housing end face flange ring welding equipment includes: a body 1, and a bracket 2 fixedly mounted on the top of the body 1, wherein a ball bearing 3 is rolledly installed on the arc-shaped concave surface at the top of the bracket 2. Welding mechanism 4 includes auxiliary component 41 and welding gun 42. Auxiliary component 41 is installed on the side of the top of body 1, and welding gun 42 is installed on the top of auxiliary component 41. The auxiliary component 41 includes a flue gas processor 411 and a rotating support base 412. The flue gas processor 411 is fixedly installed on the side of the top of the body 1. The rotating support base 412 is fixedly installed on the top of the body 1 and close to the flue gas processor 411. A welding host 413 is fixedly installed on the top of the flue gas processor 411. A mechanical arm 414 is installed on the top of the rotating support base 412. A mechanical arm 415 is installed on the end of the mechanical arm 414 away from the rotating support base 412. A welding torch 42 is installed on the top of the mechanical arm 415. A cone is fixedly connected to the top of the welding torch 42. The cone-shaped hopper 416 is connected to the flue gas processor 411 by a gas pipe 417. The rotating support 412 is activated to start the operation. The rotation of the rotating support 412 drives the mechanical arm 414 to rotate, adjusting the position of the mechanical arm 414. The mechanical arm 415 rotates and adjusts its position along with the mechanical arm 414. Under the linkage of the mechanical arm 414 and the mechanical arm 415, the position of the welding gun 42 is adjusted, which helps the welding gun 42 to be aligned with the weld seam between the end face of the tank circuit breaker housing and the flange ring, thereby promoting accurate welding.

[0025] The welding gun 42 is installed at an angle and is electrically connected to the welding host 413 via a wire. It is drawn in by a fan in the fume processor 411 and then through the air pipe 417. This allows the conical bucket 416 to absorb the fumes generated during the welding process of the welding gun 42. The air pipe 417 then transports the fumes to the fume processor 411 for timely treatment.

[0026] The air pipe 417 is curved and connects the flue gas processor 411 with the conical hopper 416.

[0027] Example 2, based on Example 1, see [link / reference] Figures 1 to 6 * Provides a technical solution: Adjustment mechanism 5 includes a lifting worktable 51 and a rotating table 52. The lifting worktable 51 is fixedly installed on the top of the machine body 1 and near the bracket 2. The rotating table 52 is fixedly installed on the top of the lifting worktable 51. A bracket 53 is fixedly connected to the top of the rotating table 52. A conical roller 54 is rolled on the top of the bracket 53. A servo motor 55 is fixedly installed on the surface of the bracket 53. A linear groove 56 is formed on the conical surface of the outer side of the conical roller 54. The tank-type circuit breaker housing to be welded is placed on the top of the bracket 2, and the bottom of the tank-type circuit breaker housing is in contact with the ball bearing 3. In the initial state, the conical roller 54 is separated from the tank-type circuit breaker housing to be welded, and the rotating table 52 is turned on to work. The rotating table 52 drives the conical roller 54 to rotate, so that the two relatively symmetrical conical rollers rotate. With the cones of the head rollers 54 facing each other, a V-shaped opening is formed by the conical surfaces of the two symmetrical cone rollers 54. At this time, the rotation of the rotary table 52 is paused, and the lifting worktable 51 is activated. The lifting worktable 51 pushes the rotary table 52 upward, causing the two symmetrical cone rollers 54 to move upward. By having the outer circular surface of the tank-type circuit breaker housing fit into the conical surface of the cone rollers 54, the servo motor 55 can be activated. The output end of the servo motor 55 drives the cone rollers 54 to rotate, so that the spiral linear groove 56 is always in contact with the outer circular surface of the tank-type circuit breaker housing, which increases the friction and allows the tank-type circuit breaker housing to be transported. This allows the tank-type circuit breaker housing to move as a whole, and the position of the tank-type circuit breaker housing can be finely adjusted to facilitate the docking of the end of the tank-type circuit breaker housing with the flange ring.

[0028] There are two rotary tables 52, and the two rotary tables 52 are symmetrically installed along the central axis in the middle of the lifting worktable 51. The conical rollers 54 are installed directly above the rotary tables 52.

[0029] The central shaft of the conical roller 54 is fixedly installed to the output end of the servo motor 55 via a coupling. The linear groove 56 is spiral-shaped and is evenly distributed on the conical surface on the outer side of the conical roller 54.

[0030] After the end of the tank-type circuit breaker housing is aligned with the flange ring, the lifting platform 51 is activated again. The lifting platform 51 moves the rotary table 52 downward, causing the conical roller 54 to move downward. The rotary table 52 then rotates the conical roller 54 in the opposite direction, making the two symmetrical conical rollers 54 parallel. The lifting platform 51 then moves the rotary table 52 upward again, causing the conical roller 54 to move upward and its outer surface to align with the outer surface of the tank-type circuit breaker housing. The lifting platform 51 is then paused, stopping the conical roller 54 from moving upward. The servo motor 55 is then activated, driving the conical roller 54 to roll through its output. Since the two opposing conical rollers 54 roll in the same direction, the tank-type circuit breaker housing can be rotated, facilitating circumferential welding of the tank-type circuit breaker housing. The continuous movement of the conical roller 54 enables multiple functions.

[0031] Example 3, based on Examples 1 and 2, see [reference] Figures 1 to 8 A technical solution is provided: The flange ring feeding mechanism 6 includes a mover 61 and an annular frame 62. The mover 61 is installed on the side of the top of the machine body 1, and the annular frame 62 is installed on top of the mover 61. A cylinder 63 is rotatably installed inside the annular frame 62. A telescopic device 64 is installed on the side of the outer side of the cylinder 63. A clamping head 65 is fixedly connected to the telescopic end of the telescopic device 64. A groove 66 is opened at the corner of the inner side of the clamping head 65. A pressing assembly 67 is installed on the top of the annular frame 62. The edge of the flange ring is embedded in the groove 66, so that the inner side of the clamping head 65 is fully in contact with the surface of the flange ring, limiting the flange ring. By extending the telescopic end of the telescopic device 64, the three evenly distributed clamping heads 65 move towards the center of the cylinder 63, which can self-center and clamp the flange ring, preventing the flange ring from shifting or tilting. At the same time, by moving the clamping heads 65 inward, it can adapt to flange rings of the same diameter, which is highly adaptable.

[0032] The axis of the cylinder 63 coincides with the center of the ring frame 62, and the clamping head 65 is installed at the port inside the cylinder 63.

[0033] The mover 61 includes a linear guide rail 611, which is fixedly installed on the side of the top of the machine body 1. A gantry frame 612 is mounted on the top of the linear guide rail 611. A stepper motor 613 is fixedly installed on the side of the surface of the gantry frame 612. The output end of the stepper motor 613 is engaged with the surface of the linear guide rail 611 via a gear and rack. A linear driver 614 is fixedly installed on the top of the inner cavity of the gantry frame 612. The telescopic end of the linear driver 614 is fixedly installed on the side of the surface of the ring frame 62. After the clamping head 65 has finished centering and clamping the flange ring, the stepper motor 613 is turned on to work. Combined with the gear and rack engagement between the output end of the stepper motor 613 and the surface of the linear guide rail 611, and under the guidance of the linear guide rail 611, the gantry frame 612 drives the ring frame 62 and the cylinder 63 to move quickly towards the position close to the tank-type circuit breaker housing, reducing the auxiliary time for flange ring docking inside the cylinder 63. When the flange ring moves to the designated position, the stepper motor 613 can be paused to stop its movement, and the linear driver 614 can be activated. By extending the telescopic end of the linear driver 614, the ring frame 62 and the cylinder 63 can be pushed upwards, thereby adjusting the height of the flange ring. Once the flange ring is adjusted to the same height as the tank circuit breaker housing, the linear driver 614 can be paused, and the cylinder 671 can be activated. By extending the telescopic end of the cylinder 671 and connecting it with the connecting plate 672, the clamping member 673 moves downwards, and the cylindrical wheel 674 moves downwards along with the clamping member 673. The cylindrical wheel 674 fits against the top of the outer circular surface of the tank circuit breaker housing, rolling and pressing the tank circuit breaker housing. The ring frame 62 provides rotational support for the cylinder 63, so that when the end face of the tank circuit breaker housing is circumferentially welded, the flange ring will rotate circumferentially with the tank circuit breaker housing, making it less likely for the structure to jam.

[0034] The pressing assembly 67 includes a cylinder 671, which is fixedly installed on the top of the ring frame 62. A connecting plate 672 is fixedly installed on the telescopic end of the cylinder 671. A clamping member 673 is fixedly connected to the bottom of the connecting plate 672 and the end away from the cylinder 671. A cylindrical wheel 674 is rolled on the inner side of the clamping member 673.

[0035] In use, first place the tank-type circuit breaker housing to be welded on the top of the bracket 2, then place the flange ring to be welded on the clamping head 65 inside the cylinder 63, with the edge of the flange ring embedded in the groove 66, so that the inner side of the clamping head 65 is fully in contact with the surface of the flange ring, limiting the flange ring. By using the extension of the telescopic end of the telescopic device 64, the three evenly distributed clamping heads 65 move towards the center of the cylinder 63, so that the flange ring can be self-centered and clamped and fixed. After the clamping head 65 has finished centering and clamping the flange ring, the operator starts the stepper motor 613. The output end of the stepper motor 613 is connected to the surface of the linear guide rail 611 through gear and rack meshing. Under the guidance of the linear guide rail 611, the gantry 612 drives the ring frame 62 and the cylinder 63 to move quickly towards the position close to the tank circuit breaker housing, reducing the flange ring docking auxiliary time in the cylinder 63. When the flange ring moves to the designated position, the stepper motor 613 can be paused to stop the flange ring movement, and the linear driver 614 can be started. By using the extension of the telescopic end of the linear driver 614, the ring frame 62 and the cylinder 63 can be pushed upward, so that the height of the flange ring can be adjusted. When the flange ring is adjusted to the same height as the tank circuit breaker housing, the linear driver 614 can be paused. The rotary table 52 is then activated to operate, driving the conical rollers 54 to rotate. This causes the two symmetrical conical rollers 54 to face each other, forming a V-shaped opening with their conical surfaces. The rotary table 52 is then paused, and the lifting platform 51 is activated to operate. The lifting platform 51 pushes the rotary table 52 upward, causing the two symmetrical conical rollers 54 to move upward. The outer circular surface of the tank-type circuit breaker housing is then in contact with the conical surface of the conical rollers 54. The servo motor 55 is then activated to operate, driving the conical rollers 54 to rotate. This ensures that the spiral linear groove 56 remains in contact with the outer circular surface of the tank-type circuit breaker housing, increasing friction and allowing the tank-type circuit breaker housing to be transported. This allows the tank-type circuit breaker housing to move as a whole, and the position of the tank-type circuit breaker housing can be finely adjusted to facilitate the connection between the end of the tank-type circuit breaker housing and the flange ring. After the end of the tank-type circuit breaker housing is aligned with the flange ring, the lifting platform 51 is activated again. The lifting platform 51 moves the rotary table 52 downward, causing the conical roller 54 to move downward. The rotary table 52 then rotates the conical roller 54 in the opposite direction, making the two symmetrical conical rollers 54 parallel. The lifting platform 51 then moves the rotary table 52 upward again, causing the conical roller 54 to move upward. The outer surface of the conical roller 54 is then in contact with the outer surface of the tank-type circuit breaker housing. The lifting platform 51 is then paused, stopping the conical roller 54 from moving upward. The servo motor 55 is then activated, and its output drives the conical roller 54 to roll. Since the two opposing conical rollers 54 roll in the same direction, the tank-type circuit breaker housing can be rotated. At this time, the cylinder 671 is activated to work. By extending the telescopic end of the cylinder 671 and connecting it with the connecting plate 672, the clamping member 673 moves downward, and the cylindrical wheel 674 moves downward along with the clamping member 673. The cylindrical wheel 674 fits against the top of the outer circular surface of the tank-type circuit breaker housing, and the cylindrical wheel 674 rolls and presses the tank-type circuit breaker housing. Furthermore, when the operator starts the rotating support 412, the rotation of the rotating support 412 drives the mechanical arm 414 to rotate, adjusting its position. The mechanical arm 415 also rotates and adjusts its position along with the mechanical arm 414. Under the linkage of the mechanical arm 414 and the mechanical arm 415, the position of the welding gun 42 is adjusted, which helps the welding gun 42 to be aligned with the weld between the end face of the tank circuit breaker housing and the flange ring. Moreover, the cylinder 63 is rotated and supported by the ring frame 62, so that when the end face of the tank circuit breaker housing is circumferentially welded, the flange ring will rotate circumferentially with the tank circuit breaker housing, making it less likely for the structure to jam, thereby promoting accurate welding. The smoke is drawn in by the fan in the flue gas processor 411 and through the connection of the air pipe 417, so that the cone bucket 416 absorbs the smoke generated when the welding gun 42 is welding. The air pipe 417 delivers the smoke to the flue gas processor 411 for timely treatment. After welding is completed, the expansion joint 64 retracts, the clamping head 65 moves outward, the clamping head 65 releases the flange ring, and the cylinder 671 is activated again. The expansion joint of the cylinder 671 retracts, and with the connection of the connecting plate 672, the clamping member 673 moves upward. The cylindrical wheel 674 makes rolling contact with the tank circuit breaker housing, and the output of the stepper motor 613 rotates in the opposite direction, causing the gantry 612 to drive the ring frame 62 and the cylinder 63 to move in the opposite direction, which facilitates the unloading of the welded tank circuit breaker.
