Specific embodiments

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] Please refer to Figure 1 and Figure 2 , the present utility model provides a technical solution: an auxiliary device for electromechanical engineering construction, including a base 1. A fixing frame 2 for fixing welded pipes is installed on the top of the base 1. A cross frame 3 is installed between two groups of fixing frames 2. A cylinder 4 is installed at the bottom of the cross frame 3. The bottom of the cylinder 4 is connected to a connecting platform 5. A welding head 6 for welding pipes is installed at the bottom of the connecting platform 5. The welding head 6 is lifted and lowered through the connecting platform 5. Guide columns for guiding are installed on both sides of the connecting platform 5. The connecting platform 5 can be prevented from tilting during lifting through the guide columns.

[0028] In Figure 1 and Figure 2 : Place the pipes for electromechanical construction to be welded in the fixing frame 2 and fix them. Then, drive the welding head 6 to move downward through the cylinder 4. At this time, the welding head 6 can weld the pipes. At the same time, continuously rotate the pipes to be welded, and circular welding of the pipes can be performed.

[0029] In Figure 2 and Figure 4In the middle: A fixed block 7 is installed inside the fixing frame 2. A connecting shaft 8 is installed in the middle of the fixed block 7. A gear 9 and a connecting block 10 are respectively installed on the outer side of the connecting shaft 8. The connecting block 10 rotates through the connecting shaft 8 with the gear 9. One side of the connecting block 10 is connected with a guide wheel 11. The guide wheel 11 can rotate through the connecting block 10 and the connecting shaft 8. The guide wheel 11 can rotate the pipeline. The outer side of the gear 9 is meshed and connected with an internal gear ring 12.

[0030] In Figure 2 and Figure 4 In the middle: Place the pipeline to be welded in the fixing frame 2. At this time, when the internal gear ring 12 rotates, it will drive the gear 9 to rotate. And the gear 9 is connected to the outer side of the connecting shaft 8. Therefore, when the gear 9 rotates, it will drive the connecting block 10 to rotate through the connecting shaft 8, so as to adjust the angle of the connecting block 10. A guide wheel 11 is installed on one side of the connecting block 10, and the guide wheel 11 will also rotate accordingly. When the guide wheel 11 rotates close to the inner wall of the fixing frame 2, it can guide and limit the pipeline with a larger size. On the contrary, when the guide wheel 11 moves in the opposite direction, it can guide and limit the pipeline with a smaller size, thus facilitating the welding of pipelines with different sizes. At the same time, the pipeline can be rotated through the guide wheel 11.

[0031] In Figure 2 and Figure 4 In the middle: A worm gear 13 is installed on the outer side of the internal gear ring 12. The worm gear 13 is rotatably connected inside the fixing frame 2. The rotation of the worm gear 13 will drive the internal gear ring 12 inside to rotate synchronously. One side of the worm gear 13 is meshed and connected with a worm 14 for driving its rotation.

[0032] In Figure 2 and Figure 4 In the middle: By rotating the worm 14, the worm 14 drives the worm gear 13 to rotate. And the worm gear 13 is connected with the internal gear ring 12. Therefore, the worm 14 will drive the internal gear ring 12 to rotate through the worm gear 13, so that the connecting block 10 drives the guide wheel 11 to rotate, facilitating the limiting and guiding of the pipeline and making the pipeline not easy to displace during welding.

[0033] In Figure 1 , Figure 3 , Figure 5 and Figure 6 In the middle: A connecting frame 15 penetrates through the middle of the connecting platform 5. The bottom of the connecting frame 15 is connected with a protective cover 16. A grinding disc 17 is installed in the slot in the middle of the protective cover 16. The middle of the grinding disc 17 penetrates through the protective cover 16 and is connected with a motor 18 for driving its rotation through an output shaft.

[0034] In Figure 1 , Figure 3 , Figure 5 and Figure 6In the middle: The grinding disc 17 in the middle of the protective cover 16 can be driven to rotate by the motor 18. When the grinding disc 17 rotates, it can grind the welded part of the pipeline, avoiding the appearance of burrs after welding. At the same time, the stability of the grinding disc 17 is increased through the connecting frame 15.

[0035] In Figure 3 、 Figure 5 and Figure 6 In the middle: An inclined groove is formed on one side of the top of the connecting frame 15. A slider 19 is slidably connected in the chute on the inclined surface of the inclined groove. A movable block 20 is installed at the bottom of the slider 19. The movable block 20 is slidably connected to the inside of the inclined groove through the slider 19. One side of the movable block 20 is connected to a screw rod 21 through a bearing. A convex block 22 is installed on the outer side of the screw rod 21. The convex block 22 is installed at the bottom of the connecting platform 5, and the convex block 22 is threadedly connected to the screw rod 21.

[0036] In Figure 3 、 Figure 5 and Figure 6 In the middle: The screw rod 21 can be rotated. Since the screw rod 21 is connected to the movable block 20 through a bearing and the screw rod 21 is threadedly connected to the convex block 22, rotating the screw rod 21 will drive the movable block 20 to move. The top of the movable block 20 is slidably connected to the inclined groove of the connecting frame 15 through the slider 19. Therefore, the movement of the movable block 20 will drive the connecting frame 15 to slide up and down along the connecting platform 5 through the cooperation of the slider 19 and the inclined groove. The up and down movement of the connecting frame 15 can drive the grinding disc 17 at the bottom to move, so that the grinding disc 17 can be moved to one side of the pipeline, making the grinding disc 17 more closely attached to the pipeline and facilitating the grinding of the pipeline.
