Description
Technical Field
[0001] The utility model belongs to the technical field of transformer oil collecting pipe welding, and specifically relates to a welding position changing device for a transformer oil collecting pipe. Background Art
[0002] A transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. Its main components are the primary coil, secondary coil, and iron core (magnetic core). Its main functions include: voltage transformation, current transformation, impedance transformation, isolation, voltage stabilization (magnetic saturation transformer), etc. Transformers are basic equipment for power transmission and distribution and are widely used in industries, agriculture, transportation, urban communities, and other fields.
[0003] When a transformer is operating, the heat generated by the losses in the windings and iron core must be dissipated in time to prevent insulation damage due to overheating. For small-capacity transformers, the ratio of the outer surface area to the transformer volume is relatively large, and the self-cooling method can be used to dissipate the heat through radiation and natural convection. Since the loss of the transformer is proportional to its volume, as the capacity of the transformer increases, its volume and loss will increase in proportion to the cube of the iron core size, while the outer surface area only increases in proportion to the square of the size. Therefore, the iron core and windings of large-capacity transformers should be immersed in oil.
[0004] In the cooling system of larger-capacity transformers, forced circulation of oil and external cooling are required. In this case, an oil collecting pipe is used to collect the cooling oil of the transformer. As Figure 4 shown, the main pipe of the oil collecting pipe generally uses square steel pipes, rectangular steel pipes, or round steel pipes. When manufacturing the oil collecting pipe, two main pipe flanges need to be welded at both ends of the main pipe of the oil collecting pipe, several pipe joints I need to be welded on the upper side of the oil collecting pipe, and two pipe joints II need to be welded on the lower side of the oil collecting pipe. The traditional welding method for transformer oil collecting pipes uses a traveling crane for hoisting and welding, which will cause problems such as shaking of the welded oil collecting pipe, poor welding quality, poor safety, and low welding efficiency. Content of the Utility Model
[0005] To solve the problems of using a traveling crane for hoisting and welding the transformer oil collecting pipe, which will cause problems such as shaking of the welded oil collecting pipe, poor welding quality, poor safety, and low welding efficiency, the utility model provides a welding position changing device and a welding workstation for a transformer oil collecting pipe.

Obviously, the embodiments described below are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in this patent, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of this patent.
[0027] As Figures 1-4 shown, the present utility model discloses a welding positioner for a transformer oil collecting pipe, which includes a second base 4 in the left-right direction. A headstock 5 is fixedly installed at one end of the second base 4. A tailstock 6 is adjustably and slidably installed on the second base 4 along its length direction (left-right direction). Between the headstock 5 and the tailstock 6, two lifting brackets 7 capable of lifting and supporting the transformer oil collecting pipe (main pipe of oil collecting pipe 1) are adjustably and slidably installed along the length direction of the second base 4; A slewing mechanism is installed on the headstock 5 and the tailstock 6, and a chuck 8 capable of clamping the main pipe flange 11 of the transformer oil collecting pipe is installed on the slewing mechanism.
[0028] First, manually spot-weld the transformer oil collecting pipe (the main pipe 1 of the oil collecting pipe and the two main pipe flanges 11, the main pipe 1 of the oil collecting pipe and the pipe joint 13, the pipe joint 12); then hoist (using a crane) the transformer oil collecting pipe onto the two lifting brackets 7; control the lifting brackets 7 to adjust the lifting of the transformer oil collecting pipe so that the main pipe 1 of the oil collecting pipe is at the same height as the chuck 8; control the two lifting brackets 7 to drive the transformer oil collecting pipe to move towards the headstock 5 side synchronously, so that the chuck 8 on the headstock 5 clamps the main pipe flange 11 at one end; control the tailstock 6 to move closer to the headstock 5, and clamp the main pipe flange 11 at the other end through the chuck 8 on the tailstock 6; control the lifting brackets 7 to descend, and adjust the left and right positions of the lifting brackets 7 (the pipe joint 13 and the pipe joint 12 rotate to avoid interference); perform welding operations. During the welding process, by controlling the synchronous rotation of the slewing mechanisms on the headstock 5 and the tailstock 6, the flexible flipping and adjustment of the transformer oil collecting pipe can be realized, thus achieving the convenience, reliability, efficiency and safety of the welding of the transformer oil collecting pipe. After the welding is completed, the lifting brackets 7 move and rise to support the transformer oil collecting pipe, the chuck 8 is released, the tailstock 6 retracts, and the lifting brackets 7 drive the transformer oil collecting pipe to move away from the headstock 5 side, and hoist the transformer oil collecting pipe to complete the entire welding process.

By driving the gears to rotate through the moving adjustment motors, and the gears are meshed with the second rack 42, the flexible, precise and reliable moving adjustment of the lifting brackets 7 and the tailstock 6 can be realized.
[0031] Among them, second limit blocks 43 that can limit the tailstock 6 and the lifting brackets 7 are respectively installed at both ends of the second base 4. Hard limits for the tailstock 6 and the lifting brackets 7 are realized to avoid derailment.
[0032] Among them, as Figure 3As shown in the figure, the lifting bracket 7 includes a bracket support 71 that can be slidably adjusted and installed on the second base 4.

The screw rod of the elevating mechanism 73 is located between the two guide rods 74; accurate and stable lifting adjustment of the elevating platform 75 can be realized.
[0036] Among them, as Figure 3 shown, four jaws 81 are installed on the chuck 8, and the jaws 81 are provided with a double-step structure; the outer step sizes of the four jaws 81 are the same; two opposite jaws 81 form a group, and the inner step sizes of each group of jaws 81 are the same, and the inner step sizes between the two groups of jaws 81 are different, that is, the inner step size of one group of jaws 81 is larger, and the inner step size of the other group is smaller. It can be adaptively clamped to the main pipe flanges 11 (with the same shape as the main oil collecting pipe 1) at both ends of the main oil collecting pipe 1 of square steel pipes, rectangular steel pipes, and circular steel pipes, with good versatility.
[0037] As Figures 1-2 shown, the present utility model also discloses a welding workstation for a transformer oil collecting pipe, including a welding robot 9 and the above-mentioned welding displacement device for the transformer oil collecting pipe.

By driving the gear to rotate by the moving adjustment motor, the gear meshes with the first rack 22, so that the left and right flexible adjustment of the bracket 3 (welding robot 9) can be realized, and thus it can be flexibly applied to the welding operation of longer transformer oil collecting pipes.
[0039] Furthermore, first limit blocks 23 are installed at both ends of the first base 2 for hard limiting of the bracket 3 to prevent derailment and ensure the safety of use.
