Description

Technical Field

[0001] The utility model relates to the technical field of tower pole production, in particular to a clamping tooling, a roller assembly and a workstation for welding a tower pole and a base flange including the two. Background Art

[0002] A tower pole is a pole that supports a transmission line and keeps a certain distance from the ground. During the production process of the tower pole, a flange base needs to be welded at its bottom so as to install the tower pole on a foundation base at a preset position subsequently. Since flange welding is circumferential welding and both the inner and outer fillet welds need to be fully welded, the tower pole also needs to be rotated and positioned during the welding process to ensure the welding quality.

[0003] The following problems will occur at this time:

[0004] 1. Most traditional tower poles are round pipes or multi-faceted pipes; most devices on the market mainly weld round pipes and flanges, and cannot solve the compatibility problem that the same device can drive both multi-faceted pipes and round pipes to rotate.

[0005] 2. The tower pole is relatively long. When the end rotates during welding, the entire tower pole will also rotate accordingly. During the rotation process, the other end of the tower pole needs to be supported, otherwise the other side of the tower pole will swing, affecting the welding quality and being unsafe. However, the existing equipment for supporting the tower pole cannot adjust the support height according to different working conditions, affecting the welding efficiency of the tower pole and the base flange.

[0006] 3. The traditional tower pole welding method is that the operator erects the tower pole on the ground to make it leave the ground, which is convenient for the operator to assemble and fix the end flange. The operator fixes the end flange according to the requirements of the drawing, and the weights of the tower pole and the flange are relatively heavy, increasing the difficulty of flipping. The operator is prone to safety accidents during the hoisting process. Summary of the Invention

[0008] Specifically, in order to solve the problem that the existing equipment cannot drive tower poles of various shapes to rotate simultaneously, a clamping device arranged along the middle opening of the clamping tooling sleeved on the outer side of the tower pole is used to tighten the tower pole, so as to convert the tower pole with different outer side shapes into the outer side of a circular clamping seat, thereby solving the compatibility problem that the same equipment cannot drive tower poles of various different shapes to rotate;

[0009] Specifically, to solve the problem that the supporting equipment of the existing tower pole cannot adjust the supporting height, the roller in the roller assembly capable of lifting is set to support the clamping tooling, which improves the stability of the tower pole during rotation, can adapt to the welding work of tower poles of various heights, and improves the welding efficiency of the tower pole and the base flange;

[0010] Specifically, to solve the problems that the welding of the existing tower pole and the flange is inconvenient and prone to safety accidents, the positioner in the workstation for welding the tower pole and the base flange drives the tower pole and the base flange to rotate, and the clamping tooling and the roller assembly cooperate to realize the stability of the rotation of the tower pole and the base flange. Then, the working arm at the appropriate position of the sliding table works to perform full welding on the inner and outer corners of the tower pole and the base flange. The automatic welding working arm improves the welding efficiency and reduces the labor cost.

[0011] To achieve the above object, the technical solution of the present utility model is:

[0018] Further, the base includes a second support base and a third support base relatively fixed below the second support base. The lifting mechanism is arranged on the second support base. A support column is arranged between the second support base and the first support base. One end of the support column is fixed to the lower side of the first support base, and the other end passes through the second support base and is slidably connected to the second support base.

[0042] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments:

[0043] Embodiment 1

[0044] As Figure 1 shown, this embodiment provides a clamping tooling 1, including a clamping seat 11. The clamping seat 11 is circular, and an opening 12 for passing through the tower pole 101 is provided in the middle thereof. Four tightening mechanisms are fixed on the outer periphery of the opening 12, and the four tightening mechanisms are evenly arranged circumferentially around the middle of the opening 12.

[0045] Specifically, the opening 12 is square. In some other embodiments, the opening 12 can be circular or other shapes that can accommodate the tower pole 101.

[0046] Specifically, a plurality of circular holes are evenly formed on the clamping seat 11, which can save materials and reduce the weight of the clamping tooling 1 at the same time.

[0047] Specifically, the tightening mechanism includes a fixed seat 13 fixed on the clamping seat 11 and a fixed rod 14 fixed on the side of the fixed seat 13 for tightening the tower pole 101. The fixed rod 13 is a screw rod, and a nut 16 is threadedly connected to the fixed rod 14. The nut 16 contacts the fixed seat 13 for limiting the fixed rod 14.

[0048] In this embodiment, in order to improve the clamping stability of the tower pole 101, two fixed rods 14 are threadedly connected to each fixed seat 13. The nut 16 on the fixed rod 14 is located between the fixed rod 14 and the fixed seat 13, and the nut 16 contacts the fixed seat 13. In another implementable embodiment, the nut 16 is located on the side where the fixed rod 14 passes through the fixed seat 13, and the function is the same as that of the above embodiment, which is to limit the fixed rod 14 so that the fixed rod 14 can better tighten the tower pole 101.

[0049] Specifically, the clamping seat 11 is a split structure. The clamping seat 11 includes a first clamping part and a second clamping part. One end of the first clamping part and the second clamping part is detachably connected, and the other end is detachably connected or hinged.

[0050] In this embodiment, both ends of the first clamping part and the second clamping part are fixed with mounting seats 15, and the two mounting seats 15 are fixed by bolts. In another practicable manner, one end of the first clamping part and the second clamping part corresponding to each other is hinged together by a hinge shaft (not shown in the figure), and the other end is fixed by passing bolts through the two corresponding mounting seats 15. The advantage of this connection method is that only one end needs to be fixed, which reduces the assembly time, and the first clamping part and the second clamping part always have one end connected together, so they are not easy to lose when placed.

[0051] In this embodiment, the first clamping portion and the second clamping portion are both semicircular, and the two form a circular clamping seat 11. In other embodiments, the first clamping portion can be the larger half of the circle, and the second clamping portion can be the smaller half of the circle, and the two form a circular clamping seat 11.

[0052] When the clamping tool 1 is used and sleeved on the outside of the tower 101, the first clamping part and the second clamping part separated by the clamping seat 11 are correspondingly sleeved on the outside of the tower 101, and the corresponding ends of the first clamping part and the second clamping part are fixed together by bolts. At this time, the tower 101 is supported by two fixing rods 14 threadedly connected to the fixing seat 13, and the four tightening mechanisms support the side of the tower 101 in turn, thereby realizing the conversion of the tower 101 with different outer side shapes into the outer side of the circular clamping seat 11, which is convenient for the external machinery to drive the rotation of the tower 101.

[0053] Example 2

[0054] like Figures 2 to 4 As shown, the difference from the above embodiment is that this embodiment provides a roller assembly 2 for supporting the clamping tool 1, including a base, a lifting mechanism is provided above the base, a first support seat 21 is provided on the lifting mechanism, the lifting mechanism is used to drive the first support seat 21 to move up and down, and the first support seat 21 is provided with a group of two rollers 22 rotatably connected to the first support seat 21.

[0055] Specifically, the base includes a second support seat 24 and a third support seat 25 relatively fixed below the second support seat 25. The lifting mechanism is arranged on the second support seat 24. Two support columns 26 are arranged between the second support seat 24 and the first support seat 21. One end of the support column 26 is fixed to the lower side of the first support seat 21, and the other end passes through the second support seat 24 and is slidably connected to the second support seat 25.

[0056] In this embodiment, the lifting mechanism is a worm and worm gear lift 23. The worm and worm gear lift 23 includes a worm gear 233 and a worm 231. The worm gear 233 is in transmission connection with the worm 231. A vertical first screw rod 232 is threadedly connected in the worm gear 233. One end of the screw rod 232 passes through the second support seat 24 and is slidably connected to the second support seat 24, and the other end is rotatably fixed to the lower side of the first support seat 21 (not shown in the figure). In another implementable manner, the lifting mechanism can also adopt an oil cylinder or a cylinder.

[0057] In this embodiment, an integrally formed outer shell is provided on the outer sides of the worm gear 233 and the worm 231. The outer shell is fixedly connected to the second support seat 24. The worm gear 233 and the worm 231 can rotate inside the outer shell. A handle 28 is fixed to one end of the worm 231 away from the second support seat 24. Manually rotating the handle 28 drives the worm 231 to rotate, and the worm gear 233 in transmission connection with the worm 231 rotates, thereby driving the first screw rod 232 threadedly connected in the worm gear 233 to move up and down rotatably under the first support seat 21.

[0058] Specifically, a sliding mechanism is provided on the third support seat 25. In this embodiment, the sliding mechanism is a pulley 27.

[0059] When using the idler roller assembly 2 to support the clamping tooling 1 clamping the tower pole 101, by manually rotating the handle 28, the first screw rod 232 drives the first support seat 21 to move upward, so that the two rollers 22 are respectively in contact with the outer side surface of the circular clamping tooling 1, ensuring that the axis of the tower pole 101 can always be stably maintained during rotation.

[0060] Embodiment 3

[0061] As Figures 5 to 7 shown, the difference from the above embodiment is that this embodiment provides a workstation for welding the tower pole and the base flange. In this embodiment, the tower pole 101 and the base flange 102 have been manually spot welded together before using this workstation for welding. However, this manual spot welding method is not only inefficient but also fails to meet the usage requirements that both the internal and external fillet welds of the tower pole 101 and the base flange 102 need to be fully welded. Therefore, this welding workstation is used to perform the re-welding work on the tower pole 101 and the base flange 102 that have been spot welded and fixed together.

[0062] Specifically, the workstation includes a clamping tooling 1 and an idler roller assembly 2. The idler roller assembly 2 is provided under the clamping tooling 1. The rollers 22 in the idler roller assembly 2 are in contact with the clamping seat 11 and are used to support the tower pole 101 in the clamping tooling 1. The workstation also includes a power mechanism and a working arm 103. In this embodiment, the power mechanism is a turntable 31.

[0063] When the positioner 31 works, it drives the tower pole 101 and the base flange 102 that have been spot-welded together to rotate. The tower pole 101 passes through the opening 12 on the clamping seat 11 of the clamping tooling 1, and the tightening mechanism on the clamping seat 11 tightens the tower pole 101. The working arm 103 is used to weld the tower pole 101 and the base flange 101 together, and the working arm 103 is located on one side of the power mechanism.

[0064] In this embodiment, two clamping toolings 1 are provided on the tower pole 101, and a roller assembly 2 is provided on the lower side of each clamping tooling 1 to increase the stability of the tower pole 101 during rotation and facilitate the welding work of the working arm 103.

[0065] Specifically, a chuck 32 is provided on the positioner 31. The chuck 32 is used to tighten the base flange 102, and the positioner 31 drives the base flange 102 fixed on the chuck 32 to rotate, thereby driving the tower pole 101 to rotate; the chuck 32 is a four-jaw chuck (such as Figure 6 ), and the four-jaw chuck is purchased externally. The production unit is Shandong Tianteng Machine Tool Accessories Co., Ltd., and the model is WP750-4.

[0066] In this embodiment, a slide rail 33 is provided on one side of the positioner 31 to cooperate with the sliding mechanism on the third support seat 25, and the working arm 103 is arranged on the slide table 104 and can slide on the slide table 104.

[0067] When using this workstation to weld and fix the tower pole 101 and the base flange 102, first use the four-jaw chuck 32 on the positioner 31 to fix the tower pole 101 and the base flange 102. (Since the tower pole 101 is relatively long, the tower pole 101 will swing or jump during the rotation of the tower pole 101 and the base flange 102.) At this time, the two clamping toolings 1 are respectively sleeved on the tower pole 101, so that the tower pole 101 with different outer surface shapes (such as Figure 7 is converted to the outer surface of the circular clamping seat 11 to allow the rollers 22 on the roller assembly 2 to support it;

[0068] In this process, it moves to a suitable position through the cooperation of the pulley 27 on the roller assembly 2 and the slide rail 33, and then the rollers 22 on the roller assembly 2 contact the tower pole 101 through the lifting assembly on the roller assembly 2. Then, the position of the roller assembly 2 on the slide rail 33 is fixed through 29. At this time, the positioner 31 can be started to drive the tower pole 101 and the base flange 102 to rotate, and then the working arm 103 at a suitable position on the slide table 104 works to perform full welding on the inner and outer corners of the tower pole 101 and the base flange 102.

[0069] The above-described embodiments are only the preferred embodiments of the present utility model, and do not limit the scope of implementation of the present utility model. Therefore, any equivalent changes or modifications made according to the structure, features, and principles described in the scope of the present utility model patent shall be included within the scope of the patent application of the present utility model.
