Description

Technical Field

[0001] The present invention belongs to the technical field of welding, and specifically relates to a welding device for building fire-fighting pipes. Background Art

[0002] Building fire-fighting pipes are pipe systems used to convey fire-fighting water, gas or other fire-extinguishing media in buildings, and are an important part of fire-fighting facilities. When in use, the pipes need to be spliced according to actual usage requirements to reach the appropriate length. Usually, welding is used to splice the pipes.

[0003] A patent with the publication number CN210435640U discloses a welding device for building fire-fighting pipes, including a base. A fixed seat is fixedly connected to the right side of the top of the base, and a movable seat is movably connected to the left side of the top of the base. Turntables are movably connected to the tops of the opposite sides of the fixed seat and the movable seat. Positioning mechanisms are fixedly connected to the opposite sides of the two turntables. A processing table is fixedly connected to the top of the base, two support mechanisms are fixedly connected to the top of the processing table, and a sliding mechanism is fixedly connected to the bottom of the movable seat. Through the combined use of the base, support mechanism, positioning mechanism, limiting mechanism, sliding mechanism, movable seat, processing table, fixed seat, turntable, cross plate, pull ring and limiting groove, this patent solves the problem that the existing welding device for building fire-fighting pipes is inconvenient for docking and positioning pipes, resulting in low pipe welding efficiency.

[0004] However, the above technical solution still has the following deficiencies in actual application: When two pipes need to be welded together, first place the two pipes on the support mechanism, then drive the end faces of the two pipes to fit, and then weld the joint of the pipes. Although the docking of the two pipes can be achieved in this way, when the number of pipes to be welded at one time is large, workers need to manually place the pipes on the support mechanism multiple times, which is labor-consuming. And in some cases, multiple pipes to be welded are concentrated and piled up in the same place, which is rather messy, and it is not easy for clamping structures such as manipulators to clamp and feed the pipes, thus affecting the continuous welding efficiency.

[0016] The beneficial effects of the present invention are as follows: 1. For a building fire-fighting pipeline welding device of the present invention, by using a pipeline alignment mechanism and a through-type positioning component, the end faces of multiple messy stacked pipelines can be aligned and fitted in sequence, and then welded, thus saving the process of manually placing and aligning the pipelines by workers, which is more labor-saving. Moreover, compared with the method of automatically placing the pipelines by using clamping structures such as mechanical hands, it effectively avoids the situation that multiple pipelines to be welded are concentrated and stacked at the same place and are relatively messy, and it is not easy for clamping structures such as mechanical hands to clamp and load the pipelines, which is beneficial to improving the continuous welding efficiency.

[0017] 2. For a building fire-fighting pipeline welding device of the present invention, by using a positioning auxiliary component, before the rotating cylinder moves horizontally, a rectangular channel can be formed on the conveyor belt by the first partition plate and the second partition plate, and there are no other pipelines in the rectangular channel. Then the rotating cylinder passes through the rectangular channel and positions the pipelines in the feeding channel, thus avoiding the situation that when the rotating cylinder moves horizontally, its end is blocked by other pipelines, and further preventing it from positioning the pipelines in the feeding channel, which further ensures the smooth progress of the welding work.

[0018] 3. For a building fire-fighting pipeline welding device of the present invention, by using the anti-blocking mechanism, when the conveyor belt drives the pipeline to move, it can drive the push plate to reciprocate and slide on the feeding plate. Through the reciprocating sliding of the push plate, the pipelines close to the edge of the feeding plate can be pushed away, thereby promoting their movement and avoiding the situation that the pipelines are stuck at the feeding channel, which may lead to the pipelines being unable to pass through normally and affecting the normal welding.

[0029] Specifically, in the prior art, when two pipes need to be welded together, the two pipes are first placed on the support mechanism, and then the end faces of the two pipes are driven to fit, and then the joint of the pipes is welded. Although the butt joint of the two pipes can be realized in this way, however, when the number of pipes to be welded at one time is large, the worker needs to manually place the pipes on the support mechanism multiple times, and the whole process is labor-consuming. And in some cases, multiple pipes to be welded are concentrated and piled up in the same place, which is rather messy, and it is not easy for clamping structures such as manipulators to clamp and load the pipes, thus affecting the continuous welding efficiency. Therefore, to solve the above problems, in this embodiment, when in use, it is used for welding two pipes with the same specification together; first, according to the diameter of the pipes, the bidirectional threaded rod two 30 is rotated by the motor three 13, so that the two feeding plates 12 slide simultaneously and in different directions, and the distance between the two feeding plates 12 is adjusted, so that the minimum distance between the two feeding plates 12 is greater than the diameter of one pipe and less than the diameter of two pipes. Then, the baffle three 19 is lifted and lowered by the cylinder three 17, and the distance between the baffle three 19 and the conveyor belt 8 is adjusted, and this distance is greater than the diameter of one pipe and less than the diameter of two pipes. Put multiple pipes onto the conveyor belt 8 uniformly, and the pipes are in the enclosure formed by the second baffle 18 and the feeding plate 12. Then drive the conveyor belt 8 to run. The pipes will move along with the conveyor belt 8 towards the narrowest spacing between the two feeding plates 12. Since only one pipe can be accommodated at the narrowest spacing between the two feeding plates 12 and the third baffle 19 will block the stacked pipes, so, as the conveyor belt 8 runs, one pipe will enter the narrowest spacing between the two feeding plates 12. The narrowest spacing between the two feeding plates 12 is the feeding channel. Until the end of the pipe contacts the first baffle 11. At this time, the visual inspection mechanism 31 detects the pipe, and the conveyor belt 8 stops running. The first motor 3 drives the bidirectional threaded rod 1 to rotate, and the two sliding columns 44 slide simultaneously and approach each other. The rotating cylinder 2 passes through the middle of the second baffle 18, and the end of the rotating cylinder 2 extends into the inner cavity of the pipe. The piston end of the electric push rod 40 drives the adjusting block 36 to move, and multiple fourth connecting rods 37 rotate simultaneously, and drive the adjusting rod 38 and the positioning plate 39 to move simultaneously, so that the positioning plate 39 fits against the inner wall of the pipe, and the pipe can be fixed. Then drive the first baffle 11 to rise by the first cylinder 10, so that the first baffle 11 no longer blocks the end of the pipe. Then drive the two sliding columns 44 to slide again until the end faces of the two pipes fit. At this time, the joint of the two pipes is aligned with the welding torch 32. Then drive the welding torch 32 to approach the joint of the pipes by the fourth cylinder 35. The two second motors 5 on both sides drive the rotating cylinder 2 to rotate simultaneously, so that the pipe rotates. At the same time, the welding torch 32 welds the pipe for one week. When the two pipes are welded into one body, drive the positioning plate 39 away from the inner wall of the pipe, loosen the pipe, and the positioning plate 39 moves out of the inner cavity of the pipe. The pipe then drops into the collection box 33 for collection. Then repeat the above operations, and the end faces of the subsequent multiple pipes can be aligned and welded, thus saving the process of manual placement and alignment of the pipes by workers, which is more labor-saving. And, compared with the method of automatically placing the pipes by using clamping structures such as mechanical hands, this method can move the originally messy and stacked pipes to the same place in an orderly manner, and then align and weld them, avoiding the situation that multiple pipes to be welded are concentrated and stacked in the same place and are relatively messy, and it is not easy for clamping structures such as mechanical hands to clamp and load the pipes, which is beneficial to improving the welding efficiency.

[0030] In this embodiment, as Figure 4 shown, a positioning auxiliary component is further provided on the frame 6; The positioning auxiliary component includes a second frame body 16 fixedly connected to one side of the frame 6. The middle of the upper end face of the second frame body 16 is fixedly connected with a second cylinder 15. The piston end of the second cylinder 15 is fixedly connected with a connecting plate 20. Both sides of the lower end of the connecting plate 20 are slidably connected with a first partition plate 25. One side of the first partition plate 25 is inserted and slidably connected with a second partition plate 26.

[0031] One side of the upper end of the first partition plate 25 is rotatably provided with a first connecting rod 22. One end of the first connecting rod 22 is rotatably provided with a threaded block 24. The threaded block 24 is threadedly connected with a threaded rod 23. One end of the threaded rod 23 is rotatably arranged on the connecting plate 20. One side of the connecting plate 20 is fixedly connected with a fourth motor 21. The output end of the fourth motor 21 is fixedly connected with one end of the threaded rod 23.

[0032] One side of the upper end of the second partition plate 26 is rotatably provided with a third connecting rod 29. One end of the third connecting rod 29 is rotatably provided with a second connecting rod 28. One end of the second connecting rod 28 is rotatably arranged on the first partition plate 25. One side of the first partition plate 25 is fixedly connected with a fifth motor 27. The output end of the fifth motor 27 is fixedly connected with one end of the second connecting rod 28.

[0033] Specifically, in the above embodiment, it is necessary for the end of the rotating cylinder 2 to extend into the inner cavity of the pipeline to realize the positioning of the pipeline. The initial position of the end of the rotating cylinder 2 is at the second baffle 18. When the rotating cylinder 2 moves horizontally, it will contact the other pipelines at the feeding plate 12. It is easy to occur that the end of the rotating cylinder 2 is blocked by the other pipelines, and the pipeline in the feeding channel cannot be positioned, affecting the subsequent welding work. Therefore, to solve the above problems, when using this embodiment, after a pipeline is in the feeding channel, according to the length of the pipeline, the fifth motor 27 is used to drive the second connecting rod 28 and the third connecting rod 29 to rotate, so that the second partition plate 26 slides on the first partition plate 25, and the total length formed by the first partition plate 25 and the second partition plate 26 is adjusted. The end of the second partition plate 26 is flush with one side end face of the pipeline in the feeding channel. And in the initial state, the two first partition plates 25 are attached. Then, the connecting plate 20 is driven to descend by the second cylinder 15. When the connecting plate 20 descends, if there are pipelines below the first partition plate 25 and the second partition plate 26, the pipelines will roll because of being extruded from the upper side by the first partition plate 25 and the second partition plate 26, so that the pipelines deviate from below the first partition plate 25 and the second partition plate 26 until the bottoms of the first partition plate 25 and the second partition plate 26 are attached to the surface of the conveyor belt 8. And since when the pipeline enters the feeding channel, one end of it may not have completely passed under the third baffle 19, therefore, by adjusting the total length formed by the first partition plate 25 and the second partition plate 26, it is possible to avoid the conflict between the second partition plate 26 and the pipelines in the feeding channel when the second partition plate 26 descends. Then, the fourth motor 21 is used to drive the threaded rod 23 to rotate, so that the threaded block 24 moves. Under the action of the two first connecting rods 22, the two first partition plates 25 slide on the connecting plate 20 and move away from each other. Then, a rectangular channel is formed by the first partition plates 25 and the second partition plate 26 on both sides. At this time, when the rotating cylinder 2 is driven to move horizontally, the rotating cylinder 2 will pass through the rectangular channel, and then the pipeline in the feeding channel is fixed. During the movement of the rotating cylinder 2, it will not contact the other pipelines, thus avoiding the situation that the end of the rotating cylinder 2 is blocked by the other pipelines and further unable to position the pipeline in the feeding channel, ensuring the smooth progress of the subsequent welding work.

[0034] In this embodiment, as Figure 2 andFigure 9 As shown, an anti-blocking mechanism is further provided on the feeding plate 12; The anti-blocking mechanism includes a push plate 14 inserted and slidably connected to the feeding plate 12. One side of the push plate 14 is rotatably provided with a fifth connecting rod 42. One end of the fifth connecting rod 42 is rotatably provided with a sixth connecting rod 43. One end of the sixth connecting rod 43 is rotatably provided on the feeding plate 12. One side of the feeding plate 12 is fixedly connected with a sixth motor 41. The output end of the sixth motor 41 is fixedly connected to one end of the sixth connecting rod 43.

[0035] Specifically, in the above embodiment, since multiple pipes converge towards the feeding channel through the edge of the feeding plate 12, it is easy for the pipes to be stuck at the feeding channel due to mutual extrusion, resulting in the pipes being unable to pass through normally and affecting the welding; Therefore, to solve the above problems, when in use in this embodiment, when the conveyor belt 8 drives the pipes to move, the sixth motor 41 drives the sixth connecting rod 43 to rotate continuously, then the fifth connecting rod 42 will also rotate, causing the push plate 14 to reciprocate on the feeding plate 12. Through the reciprocating sliding of the push plate 14, the pipes near the edge of the feeding plate 12 can be pushed away, thereby promoting their movement and avoiding the situation where the pipes are stuck at the feeding channel, which in turn leads to the pipes being unable to pass through normally and affecting the normal welding.

[0036] Working principle: First, according to the diameter of the pipeline, the bidirectional screw rod two 30 is driven to rotate by the motor three 13, so that the two feeding plates 12 slide simultaneously and in different directions, adjusting the distance between the two feeding plates 12, making the minimum distance between the two feeding plates 12 greater than the diameter of one pipeline and less than the diameter of two pipelines. Then, the baffle three 19 is driven to rise and fall by the cylinder three 17, adjusting the distance between the baffle three 19 and the conveyor belt 8, and this distance is greater than the diameter of one pipeline and less than the diameter of two pipelines. A plurality of pipelines are uniformly placed on the conveyor belt 8, and the pipelines are in the enclosure composed of the baffle two 18 and the feeding plates 12. Then, the conveyor belt 8 is driven to operate, and the pipelines will move along with the conveyor belt 8 towards the narrowest distance between the two feeding plates 12. Since only one pipeline can be accommodated at the narrowest distance between the two feeding plates 12, and the baffle three 19 will block the stacked pipelines, so, as the conveyor belt 8 operates, one pipeline will enter the narrowest distance between the two feeding plates 12. The narrowest distance between the two feeding plates 12 is the feeding channel. Until the end of the pipeline contacts the baffle one 11, at this time, the visual detection mechanism 31 detects the pipeline, and the conveyor belt 8 stops operating. The bidirectional screw rod one 4 is driven to rotate by the motor one 3, and the two sliding columns 44 slide simultaneously and approach each other. The rotating cylinder 2 passes through the middle of the baffle two 18, and the end of the rotating cylinder 2 extends into the inner cavity of the pipeline. The piston end of the electric push rod 40 drives the adjusting block 36 to move, and a plurality of connecting rods four 37 rotate simultaneously, driving the adjusting rod 38 and the positioning plate 39 to move simultaneously, so that the positioning plate 39 fits against the inner wall of the pipeline, and the pipeline can be fixed. Then, the baffle one 11 is driven to rise by the cylinder one 10, so that the baffle one 11 no longer blocks the end of the pipeline. Then, the two sliding columns 44 are driven to slide again until the end faces of the two pipelines are in contact. At this time, the joint of the two pipelines is aligned with the welding torch 32. Then, the welding torch 32 is driven to approach the joint of the pipelines by the cylinder four 35. The two motors two 5 on both sides drive the rotating cylinder 2 to rotate simultaneously, making the pipeline rotate. At the same time, the welding torch 32 welds the pipeline for one week. When the two pipelines are welded into one body, the positioning plate 39 is driven to move away from the inner wall of the pipeline, the pipeline is released, and the positioning plate 39 moves out of the inner cavity of the pipeline, and the pipeline then falls into the collection box 33 for collection. Then, the above operations are repeated, so that the end faces of the subsequent plurality of pipelines can be aligned and welded, thus saving the process of manually placing and aligning the pipelines by workers, which is relatively labor-saving. And, compared with the method of automatically placing the pipelines by using clamping structures such as mechanical hands, this method can make the originally messy and stacked pipelines move orderly to the same place, and then be aligned and welded, avoiding the situation that a plurality of pipelines to be welded are concentrated and stacked in the same place and are relatively messy, and it is not easy for clamping structures such as mechanical hands to clamp and load the pipelines, which is beneficial to improving the welding efficiency;After a pipe is placed in the feeding channel, according to the length of the pipe, the motor five 27 drives the connecting rod two 28 and the connecting rod three 29 to rotate, causing the partition two 26 to slide on the partition one 25, adjusting the total length formed by the partition one 25 and the partition two 26, and the end of the partition two 26 is flush with one side end face of the pipe in the feeding channel. And in the initial state, the two partitions one 25 are in contact. Then, the cylinder two 15 drives the connecting plate 20 to descend. When the connecting plate 20 descends, if there is a pipe below the partition one 25 and the partition two 26, the pipe will roll due to the extrusion from the upper side by the partition one 25 and the partition two 26, causing the pipe to deviate from below the partition one 25 and the partition two 26 until the bottoms of the partition one 25 and the partition two 26 are in contact with the surface of the conveyor belt 8. And, since when the pipe enters the feeding channel, one end of it may not have completely passed under the baffle three 19, therefore, by adjusting the total length formed by the partition one 25 and the partition two 26, it is possible to avoid a conflict between the partition two 26 when it descends and the pipe in the feeding channel. Then, the motor four 21 drives the threaded rod 23 to rotate, causing the threaded block 24 to move, and under the action of the two connecting rods one 22, the two partitions one 25 slide on the connecting plate 20 and move away from each other, so that the partitions one 25 and the partition two 26 on both sides form a rectangular channel. At this time, when the rotating cylinder 2 is driven to move horizontally, the rotating cylinder 2 will pass through the rectangular channel, and then fix the pipe in the feeding channel. During the movement of the rotating cylinder 2, it will not contact the other pipes, thus avoiding the situation where the end of the rotating cylinder 2 is blocked by the other pipes, and then being unable to position the pipe in the feeding channel, ensuring the smooth progress of the subsequent welding work; when the conveyor belt 8 drives the pipe to move, the motor six 41 drives the connecting rod six 43 to continuously rotate, then the connecting rod five 42 will also rotate, causing the push plate 14 to reciprocate on the feeding plate 12. Through the reciprocating movement of the push plate 14, the pipes close to the edge of the feeding plate 12 can be pushed away, thereby promoting their movement, avoiding the situation where the pipes are stuck at the feeding channel, and then causing the pipes to be unable to pass through normally and affecting the normal welding.
