[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are a primary coil, a secondary coil, and an iron core (magnetic core). Its primary functions include voltage conversion, current conversion, impedance conversion, isolation, and voltage regulation (magnetic saturation transformer). Transformers are essential equipment for power transmission and distribution and are widely used in industry, agriculture, transportation, urban communities, and other fields.

[0003] The transformer riser is a crucial component in transformers, supporting the transformer and improving the insulation strength of the transformer windings. It also provides overall stability and ensures proper operation. A transformer riser typically consists of a support frame and insulation supports. The support frame, the main component of the riser and typically made of metal, supports the entire transformer.

[0004] The transformer riser support frame includes a cylindrical support frame body and support frame flanges welded to both ends of the support frame body. When the transformer riser support frame is welded and manufactured, it is necessary to weld the inner and outer sides of both ends of the support frame body (the position where the support frame flanges fit together) respectively. Due to the large size of the transformer riser support frame, traditional manual welding requires workers to enter the workpiece (transformer riser support frame) to perform welding operations, which has high work intensity, low work efficiency, poor working environment and high risk. Utility Model Content

[0005] In order to solve the problems of traditional manual welding of transformer riser support frame, which requires workers to enter the workpiece to perform welding operations, has high work intensity, low work efficiency, poor working environment and high risk, the utility model provides a transformer riser support frame welding device.

[0006] The utility model is realized through the following technical solutions:

[0007] A welding device for a transformer elevating seat support frame comprises a first base, a second base and a welding robot which can be slidably adjusted and mounted on the first base.

[0008] A further improvement of the present invention is that two first guide rails and a rack are installed on the first base along its length direction, a robot base is connected to the bottom of the welding robot, a first motor is installed on the robot base, a gear meshing with the rack is connected to the output end of the first motor, and a slider slidingly matched with the first guide rail is installed on the lower side of the robot base.

[0009] A further improvement of the present invention is that limiting blocks capable of limiting the position of the robot base are installed at both ends of the first base.

[0010] A further improvement of the present invention is that the rolling bracket is slidably mounted on the second base.

[0011] Further improvements of the present invention include: two second guide rails are installed on the second base, and a screw is rotatably installed; a slider is installed at the bottom of the rolling bracket, which slides with the second guide rails, and a sleeve is installed on the screw; a second motor is also installed on the second base, which is connected to the screw transmission.

[0012] A further improvement of the present invention is that the rolling bracket includes a bracket support, a mounting frame and a roller frame; a lifting mechanism capable of driving the mounting frame to lift and lower and a third motor driving the lifting mechanism are installed on the bracket support; two opposing rollers are rotatably installed on the roller frame, and the roller frame is connected and installed on the upper side of the mounting frame.

[0025] In order to make the purpose, features, and advantages of the present invention more obvious and easy to understand, the technical solutions of the present invention will be clearly and completely described below in conjunction with the drawings in the specific embodiments. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this patent.

[0026] like Figure 1-4 As shown, the utility model discloses a welding device for a transformer elevating seat support frame, comprising a first base 2, a second base 4 and a welding robot 3 which can be slidably adjusted left and right and installed on the first base 2, a mounting seat 5 is positioned and installed at one end of the second base 4, a chuck 6 which can clamp the support frame flange 11 at one end of the transformer elevating seat support frame is installed on the mounting seat 5 through a rotating mechanism, and the rotating axis direction of the rotating mechanism is left and right; a rolling bracket 7 which can rollingly support the support frame body 1 of the transformer elevating seat support frame is installed on the second base 4; a welding channel is provided in the middle of the rotating mechanism and the chuck 6.

[0027] The support frame flange 11 at one end of the transformer riser support frame is clamped inward from the outside by a chuck 6, and the transformer riser support frame (support frame body 1) is rollingly supported by a rolling bracket 7, enabling flexible and reliable rotation of the transformer riser support frame. The welding robot 3 slides and adjusts on the first base 2, enabling convenient and efficient welding of the four inner and outer annular seams of the transformer riser support frame. When welding the inner annular seam, the welding gun extends into the interior of the transformer riser support frame from both ends (one end is inserted through the welding channel). The overall structure is simple, making welding of the transformer riser support frame convenient and efficient. Manual access to the workpiece is unnecessary, effectively preventing hazards to operators and ensuring excellent safety.

[0028] This device is suitable for welding operations on larger transformer lifting support frames.

[0029] There are at least three claws 61 to achieve accuracy and reliability in clamping the support frame flange 11 at one end of the transformer lifting stand support frame.

[0030] Among them, the rotary mechanism is a rotary worktable, which is provided with rotational power by a servo motor, and its rotation axis direction is left and right.

[0031] Two first guide rails 21 and a rack 22 are mounted along the length of the first base 2. A robot base 31 is connected to the bottom of the welding robot 3. A first motor 32 is mounted on the robot base 31. A gear meshing with the rack 22 is connected to the output end of the first motor 32. A slider is mounted on the underside of the robot base 31, which slides with the first guide rail 21. This allows for precise and smooth left and right movement of the welding robot 3.

[0032] Among them, limit blocks 23 capable of limiting the position of the robot base 31 are also installed at both ends of the first base 2. The limit blocks 23 serve as hard limits to prevent the welding robot 3 from derailing, and have good safety.

[0033] The rolling bracket 7 is mounted on the second base 4, allowing for left-right sliding adjustment. Two second guide rails 41 are mounted on the second base 4, along with screws 43 that rotate in the same direction. A slider is mounted at the bottom of the rolling bracket 7, which slidably engages with the second guide rails 41, and a sleeve is mounted, which is threadably engaged with the screws 43. A second motor 42, which is in driving connection with the screws 43, is also mounted on the second base 4. This allows for precise and smooth sliding adjustment of the rolling bracket 7 on the second base 4, providing reliable and stable rolling support for transformer riser support frames of varying sizes, with excellent versatility. The left-right movement of the rolling bracket 7 also facilitates the convenient mounting of the chuck 6 on the support frame flange 11 (moving the rolling bracket 7, which carries the transformer riser support frame, toward the chuck 6) and the convenient lifting and removal of welded workpieces (moving them away from the chuck 6).

[0034] Among them, such as Figure 4 As shown, the rolling bracket 7 includes a bracket support 71, a mounting frame 76 and a roller frame 77; the bracket support 71 is equipped with a lifting mechanism 73 capable of driving the mounting frame 76 to lift and lower, and a third motor 72 driving the lifting mechanism 73; two opposing rollers 78 are rotatably mounted on the roller frame 77, and the roller frame 77 is connected and installed on the upper side of the mounting frame 76.

[0035] The third motor 72 can drive the mounting frame 76 (roller frame 77, roller 78) to rise and fall through the lifting mechanism 73, thereby achieving convenience and flexibility in use, and can be flexibly applied to the rolling support of transformer lifting seat support frames of different sizes, with good versatility.

[0036] Furthermore, the roller frame 77 is clamped on the upper side of the mounting frame 76, and a plurality of pairs of slots are provided on the mounting frame 76. By clamping different roller frames 77 in different slots, different roller frames 77 can be installed, thereby achieving reliable and stable rolling support for transformer lifting seat support frames with different diameters.

[0037] Furthermore, two guide rods 74 connected to the lower side of the mounting frame 76 are vertically slidably mounted on the bracket support 71 , and the lifting mechanism 73 is arranged between the two guide rods 74 to achieve accurate and reliable lifting and lowering adjustment of the mounting frame 76 .

[0038] Wherein, rolling bracket 7 is set to two. Realize the stable support to the transformer raising seat support frame through two rolling brackets 7.

[0039] The two rolling brackets 7 are connected by a connecting rod 79, which is fixedly connected to one rolling bracket 7 and adjustably connected to the other rolling bracket 7. A polished rod section is provided at one end of the screw rod 43. The connecting rod 79 can be used to define the distance between the two rolling brackets 7. When the sliding sleeve on one rolling bracket 7 slides into the polished rod section, the distance between the two rolling brackets 7 can be easily adjusted, improving applicability.

[0040] Among them, the lifting mechanism 73 is a worm screw elevator, and the screw 75 of the worm screw elevator is connected to the bottom of the mounting frame 76. The lifting is stable, accurate, reliable, and has a self-locking function.

[0041] This transformer riser support frame welding device utilizes a chuck 6 to clamp a support frame flange 11 at one end of the transformer riser support frame from the outside inward, and a rolling bracket 7 to provide rolling support for the transformer riser support frame (support frame body 1). This allows for flexible and reliable rotation of the transformer riser support frame. A welding robot 3 slides and adjusts on a first base 2, enabling convenient and efficient welding of the four inner and outer annular seams of the transformer riser support frame. When welding the inner annular seam, the welding gun extends into the interior of the transformer riser support frame from both ends (one end through a welding channel). The simple overall structure facilitates convenient and efficient welding of the transformer riser support frame, eliminating the need for manual entry into the workpiece, effectively preventing hazards to operators and enhancing safety.
