Description

Technical Field

[0001] This utility model relates to the field of steel welding technology, specifically to a spherical support steel welding device. Background Technology

[0002] In the construction of bridges, large-scale building steel structures and other engineering projects, spherical bearing steel components often need to be welded and installed in high-altitude operation scenarios, such as the connection between bridge bearings and beams, and the splicing of steel structure nodes in high-rise buildings. These high-altitude welding operations place extremely high demands on the safety, convenience and stability of the equipment.

[0003] Currently, welding spherical bearing steel components requires workers to carry them to a high work platform and then manually lift and adjust them to the welding position. Because spherical bearing steel components are generally quite heavy, lifting them from a height not only consumes a lot of physical strength but also increases the risk of the components falling due to imbalance and slippage, posing a safety hazard to personnel and equipment below. Furthermore, it is difficult to ensure the precise positioning of the components at the welding station, affecting the welding quality. Utility Model Content

[0020] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0021] This utility model discloses a welding device for spherical support steel parts.

[0022] Reference Figure 1-3 A spherical support steel welding device includes a base plate 1 and two side plates 2. The two side plates 2 are fixedly installed on both sides of the middle of the upper surface of the base plate 1. A rotating rod 3 is rotatably installed between the two side plates 2. A transmission mechanism for driving the rotating rod 3 to rotate is installed on the upper surface of the base plate 1. Two L-shaped plates 5 are fixedly sleeved on the rod wall of the rotating rod 3. A welding worktable 6 is installed between the two ends of the two L-shaped plates 5. A connecting mechanism is installed at the end of each L-shaped plate 5. The end of the L-shaped plate 5 is limitedly connected to the welding worktable 6 through the connecting mechanism. A clamping mechanism is installed inside the welding worktable 6.

[0023] Reference Figure 1-3The transmission mechanism includes a gear 4 and a rack 15. The gear 4 is fixedly sleeved on the middle end of the rotating rod 3. The rack 15 is meshed on the lower side of the gear 4. Support plates 13 are fixedly installed on the upper surface of the base plate 1 and on both sides of the rack 15. A lead screw 11 is rotatably installed between the two support plates 13. The rack 15 is threadedly sleeved with the lead screw 11. A motor 14 is fixedly installed on the outer side of one support plate 13. The output end of the motor 14 is fixedly connected to one end of the lead screw 11. A first limiting rod 12 is arranged parallel to one side of the lead screw 11. Both ends of the first limiting rod 12 are fixedly connected to the corresponding support plate 13. One side of the rack 15 is movably sleeved with the first limiting rod 12, so that the rack 15 can slide stably.

[0024] Reference Figure 1-3 The connecting mechanism includes a wedge block 7 and a rod 17. A wedge groove is provided at the end of the L-shaped plate 5. The wedge block 7 is engaged inside the wedge groove. One side of the wedge block 7 is fixedly connected to the welding workbench 6. A fixed shell 16 is fixedly installed in the middle of the side of the welding workbench 6 near the L-shaped plate 5. Two sliders 18 are slidably arranged inside the fixed shell 16. Two rods 17 are fixedly installed on the opposite side of the two sliders 18. One end of the rod 17 extends to the outside of the fixed shell 16. An insertion hole is provided on the side wall of the L-shaped plate 5. One side of the rod 17 is inserted into the corresponding insertion hole. A spring 20 is fixedly connected between the two sliders 18. A second limiting rod 19 is fixedly installed inside the fixed shell 16. One side of each slider 18 is movably sleeved with the second limiting rod 19, so that the sliders 18 can slide stably.

[0025] Reference Figure 1-3 The clamping mechanism includes a clamping plate 8 and a threaded rod 9. A placement groove is provided on the side of the welding workbench 6 away from the L-shaped plate 5. The clamping plate 8 is slidably disposed inside the placement groove. A threaded hole is provided on one inner wall of the placement groove. The threaded rod 9 is threadedly sleeved inside the threaded hole. One end of the threaded rod 9 is rotatably connected to the clamping plate 8. Through holes are provided on both sides of the inner wall of the placement groove and on both sides of the threaded hole. A third limiting rod 10 is slidably sleeved inside the through hole. One end of the third limiting rod 10 is fixedly connected to the clamping plate 8, so that the clamping plate 8 can slide stably.

[0026] In this utility model, when in use, the spherical support steel part is first placed in the placement groove of the welding workbench 6 at a low position. The threaded rod 9 is rotated. Since the threaded rod 9 is threadedly connected to the threaded hole on the inner wall of one side of the placement groove, and the third limiting rod 10 restricts the rotation of the clamping plate 8, the rotation of the threaded rod 9 will drive the clamping plate 8 to slide along the third limiting rod 10 in the placement groove, thereby stably clamping the steel part in the placement groove. Next, the motor 14 is started. The output end of the motor 14 drives the lead screw 11 to rotate. Because the rack 15 is threadedly connected to the lead screw 11 and the first limit rod 12 restricts the rotation of the rack 15, the rack 15 can only slide horizontally on the base plate 1 along the first limit rod 12. When the rack 15 moves, it meshes with the gear 4 and drives the gear 4 to rotate. This causes the gear 4, which is fixedly sleeved on the rotating rod 3, to drive the rotating rod 3 to rotate. When the rotating rod 3 rotates, the two L-shaped plates 5, which are fixedly sleeved on its rod wall, rotate accordingly, rotating and lifting the welding workbench 6 containing the steel parts to the welding position. At the same time, the other welding workbench 6 is rotated to a lower position close to the base plate 1 to facilitate the next loading. When it is necessary to replace the welding worktable 6 with a different type to accommodate the welding of steel parts of different shapes, pull the slider 18 inside the fixed shell 16 to overcome the elastic force of the spring 20, so that the insertion rod 17 is moved out of the insertion hole on the side wall of the L-shaped plate 5. Then, pull the wedge block 7 on the welding worktable 6 out of the wedge groove at the end of the L-shaped plate 5 to disassemble the welding worktable 6. After replacing it with a suitable welding worktable 6, release the slider 18. Under the elastic force of the spring 20, the insertion rod 17 is reinserted into the insertion hole of the L-shaped plate 5, thus completing the replacement and fixing of the welding worktable 6.

[0027] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
