Description

Technical Field

[0001] This invention relates to the field of iron tower processing, specifically to an iron tower welding equipment and an iron tower welding method. Background Technology

[0002] A monotube tower is a self-supporting pole-shaped iron tower made primarily of a single large-diameter conical steel pipe. It lacks a complex truss structure, and its tower body is shaped like a cone or polygonal pyramid, tapering from top to bottom. It incorporates internal ladders and external accessory supports, and features a small footprint, low wind load, and aesthetic appeal. It is widely used in the telecommunications and power transmission fields, with two main functions: first, in the telecommunications field, it serves as a base station carrier for antenna installation, suitable for densely populated urban areas, scenic spots, and other scenarios with high aesthetic requirements, compensating for the visual interference shortcomings of traditional truss towers; second, in the power transmission field, it is used for 110kV and below medium and low voltage lines, undertaking the task of conductor suspension, suitable for the limited space requirements of urban distribution networks and suburban lines.

[0003] The production of single-tube towers is mainly prefabricated in the factory, with a streamlined process: First, the Q235B / Q345B steel plates are inspected for material and dimensions, then CNC cut into fan-shaped blanks and beveled; the steel plates are rolled into tapered tubes using a tapered plate rolling machine, and longitudinal joints are welded using submerged arc welding, with ultrasonic testing to ensure weld quality; tower sections are cut according to transportation requirements, flanges are welded and CNC drilling is performed; ladders, antenna supports, and other accessories are welded and labeled with numbers; finally, anti-corrosion treatment is completed through pickling, fluxing, and hot-dip galvanizing, and after passing inspection, the towers are shipped out and can be put into use on-site by assembling them into sections with high-strength bolts.

[0004] In the prior art, during the welding process of a single-tube tower, a gantry crane is usually used to move the welding mechanism to weld the seams on the outside of the single-tube tower. For example, Chinese Patent No. CN217019137U discloses an external seam welding machine for a single-tube tower, which includes a gantry crane located on the ground. A limiting component is installed on the side of the ground near the gantry crane, and a placement frame is provided in the middle of the limiting component. At the same time, the gantry crane includes a support leg, and a top pressure platform is connected to the middle of the support leg. First hydraulic rods are installed on both sides of the top of the top pressure platform, and a welding head is installed on one side of the middle of the top pressure platform.

[0005] However, in the existing technology, during the welding process, welding slag is easily generated inside the weld seam of the pipe, which is not easy to clean. Secondly, during the welding process, the diameter of some single-tube tower models will gradually decrease. Therefore, during the welding process, the position of the welding gun needs to be constantly adjusted. This process needs to be very precise, otherwise, incomplete welding or damage to the welding gun will occur, resulting in low efficiency. Summary of the Invention

[0008] By adopting the above technical solution, it is convenient to transport single pipe fittings, and the dust removal and cooling mechanism can uniformly cool the welded parts. After cooling, impurities are cleaned by airflow.

A guide assembly is installed on the outer wall of the gantry. The moving plate is connected to the output end of the moving motor through the screw and the guide assembly. Multiple sets of drive wheels are also installed on the outer wall of the moving plate. The drive wheels are electrically driven, and the positioning rod is connected to the drive wheels through a transmission connection.

[0012] Preferably, the movable plate can be easily moved to change the position of the welding components.

[0013] The present invention is further configured such that two sets of symmetrically arranged limiting wheels are connected to the top of the supporting component, and multiple sets of auxiliary wheels are connected below the limiting wheels, with the outer wall of the auxiliary wheels fitting against the outer wall of the limiting wheels.

[0014] Preferably, the height of the support component can be easily changed, thereby facilitating the limiting support of single pipes of different specifications.

[0015] The present invention is further configured such that a moving motor is installed on the side of the support assembly, a conveyor belt is sleeved on the outer wall of the output end of the moving motor, a moving roller is driven and connected above the conveyor belt, and support frames are installed on both sides of the inner wall of the support assembly located on the moving roller, and the moving roller is fixed inside the support frame.

[0016] Preferably, it allows for easy movement of the single pipe above the support assembly.

[0017] The present invention is further configured such that a corrugated pipe is installed inside the dust removal and cooling mechanism, a dust suction hood is connected to the outer side of the bottom end of the dust removal and cooling mechanism, the suction pipe is connected to the dust suction hood through the dust removal and cooling mechanism, and the dust suction hood has a hollow internal structure with slots at the bottom and sides.

[0018] Preferably, the dust cover can be moved up and down easily, and can also be used to cover the dust removal area to reduce the leakage of impurities.

[0019] The invention is further configured such that the bottom end of the air outlet pipe is connected to a sliding pipe, and the sliding pipe is located inside the dust removal and cooling mechanism. The bottom end of the dust removal and cooling mechanism is connected to a cooling plate, the end of the cooling plate extends to the outside of the dust collection hood, the bottom end of the cooling plate is connected to a scraper, and a bottom slope is formed above the scraper. A jet nozzle is installed at the center of the bottom slope, and a jet slot is formed at the top of the jet nozzle. A discharge slot is formed at the bottom edge of the cooling plate, and an exhaust slot is formed above the discharge slot on the cooling plate. A protective plate is connected to the bottom end of the cooling plate extending outside the dust collection hood, and the protective plate is aligned with the jet slot.

[0020] Preferably, the jet plate can easily dissipate heat evenly at the welding position, and after heat dissipation, the airflow can scrape and clean the impurities.

[0021] A method for welding iron towers, the process of which includes the following steps:

[0022] Step 1: First, move the gantry frame to the starting section via the control panel. Then, control the lifting cylinders under each set of support components to adjust the height of each set of support components. The height adjustment should be made according to the single-tube iron tower structure to be processed. Adjust the angle of the single tube to keep the slotted position on the top of the single tube horizontal.

[0023] Step 2: The bent single pipe is pushed to the bottom of the gantry by the transfer equipment, and the single pipe is transported by the support components. The moving motor is started, and the moving motor drives the moving roller to rotate through the conveyor belt. The moving roller drives the single pipe to move. During the movement, it can limit the single pipe with the limit wheel. After the height of each set of support components is adjusted, it can accurately limit and support the single pipe and keep it stable.

[0024] Step 3: Start the moving plate, move the position of the moving plate by the moving motor, and adjust the height of the positioning rod up and down by the drive wheel. At this time, the dust hood and the cooling plate first adhere to the outside of the single pipe, and then continue to push the positioning rod down until the welding head adheres to the opening of the single pipe. Then start the welding mechanism and control the feeding funnel and wire collection coil to send the welding material to the slotted position, and the welding head welds the slotted position.

[0025] Step 4: Start the gantry. The movable base under the gantry drives the gantry and the welding assembly to move synchronously, thereby welding different positions of the single pipe. During the welding process, the height of the positioning rod is controlled and adjusted by the drive wheel according to the shape of the outer side of the single pipe, so that the welding head is always in contact with the groove position of the single pipe.

[0026] Step 5: Simultaneously, the rear air outlet is connected to the external air source under positive pressure. The airflow enters the cooling plate through the air outlet and is ejected through the jet slots and jet nozzles at the bottom of the cooling plate. The jet slots face the protective plate. After the airflow hits the jet slots, it moves downward and provides heat dissipation protection for the protective plate. The downward-flowing airflow blows towards the welded position after welding, providing initial cooling. Then, the jet nozzles further cool the welded position by blowing air, thereby increasing the blowing force to facilitate uniform cooling of the welded position. Afterward, the scraper moves from above the welded area to scrape and clean the welding residue remaining in the cooled area.

[0027] Step Six: Connect the suction pipe to the negative pressure of the external air source, so that the negative pressure draws the dust collection hood into a negative pressure. When the impurities move into the dust collection hood, the airflow will suck the impurities into the dust removal and cooling mechanism, and the impurities will enter the external air source dust removal mechanism through the suction pipe, thereby cleaning the impurities during the welding process.

[0028] In summary, the present invention has the following main beneficial effects:

[0029] 1. This invention, through the setting of a gantry frame, welding components, and height-adjustable support components, allows for the installation of a single pipe component. First, the height of each set of support components is adjusted according to the structure of the single pipe component. Then, the single pipe component is placed on top of each set of support components. A moving motor drives a moving roller to rotate, which in turn moves the single pipe component. Limiting wheels limit the movement of the single pipe component, facilitating its movement and thus improving efficiency.

[0030] 2. The present invention, through the exhaust assembly, can combine the intake pipe and exhaust pipe together during use, thereby effectively reducing the space occupied. The suction pipe is on the outside, and due to the pipe material, it can effectively reduce gas loss. During use, the welding position can first be cooled in sections by airflow, so as to dissipate heat evenly and improve the heat dissipation effect. Secondly, after heat dissipation, the welding position is scraped by a scraper to clean the attached impurities. The impurities are scraped off again by airflow, which improves the cleaning effect.

[0047] For details regarding the above embodiments, please refer to [link / reference]. Figure 1 A ladder 101 is connected to the side of the gantry frame 1, which can be moved to the top of the gantry frame 1. A guardrail 105 is installed at the top of the gantry frame 1. An electrical control box 103 and an operating table 104 are respectively installed above the two sets of movable bases 102. A standing platform is installed on the side of the operating table 104.

[0048] For details regarding the above embodiments, please refer to [link / reference]. Figure 1 and Figure 2 A moving motor 6 is provided on the side of the moving plate 2. The moving motor 6 is installed on the outer wall of the gantry frame 1, and the output end of the moving motor 6 is connected to a drive screw. A guide assembly is installed on the outer wall of the gantry frame 1. The moving plate 2 is connected to the output end of the moving motor 6 through the screw and the guide assembly. Multiple sets of drive wheels 201 are also installed on the outer wall of the moving plate 2. The drive wheels 201 are driven by electricity, and the positioning rod 7 is connected to the drive wheels 201 for easy adjustment of the height of the positioning rod 7.

[0049] During operation, the gantry 1 is first moved to the starting section via the control panel 104. Then, the lifting cylinders 401 below each set of support components 4 are controlled to adjust the height of each set of support components 4. The adjusted height is adjusted according to the single-tube tower structure to be processed (generally using a pre-defined plan). For example, the taper is usually around one degree. The angle of the single tube 5 is adjusted to keep the slotted position on the top of the single tube 5 horizontal. Then, the bent single tube 5 is pushed to the bottom of the gantry 1 via a transfer device and transported by the support components 4. The moving motor 403 is started, and the moving motor 403 drives the moving roller 404 to rotate via the conveyor belt 405. The moving roller 404 moves the single tube 5. When in motion, it can limit the single pipe 5 with the limiting wheel 402, and after the height of each set of support components 4 is adjusted, it can accurately limit and support the single pipe 5, maintain stability, and prevent shaking during welding. Then, the welding wire and welding material are placed in the wire collection roll 12 and the feeding funnel 9 respectively. Then, the suction pipe 8 and the exhaust pipe 16 are connected to the external air source to enable normal use. Then, the moving plate 2 is started, and the position of the moving plate 2 is moved by the moving motor 6. The height of the positioning rod 7 is adjusted up and down by the drive wheel 201. At this time, the dust suction hood 14 and the cooling plate 15 first adhere to the outside of the single pipe 5, and then continue to push the positioning rod 7 down until the welding head 1001 adheres to the opening of the single pipe 5. Then, the welding mechanism 10 is activated, and the feeding funnel and wire collection coil 12 are controlled to deliver the welding material to the slotted position. The welding head 1001 welds at the slotted position. At this time, the operator observes the welding situation on the operating table 104. After the welding is completed, the gantry 1 is activated. The movable base 102 under the gantry 1 drives the gantry 1 and the welding assembly to move synchronously, thereby welding different positions of the single pipe 5. During the welding process, according to the shape of the outer side of the single pipe 5, the height of the positioning rod 7 is controlled and adjusted by the drive wheel 201 so that the welding head 1001 is always in contact with the slotted position of the single pipe 5, thereby continuously welding the single pipe 5. At the same time as welding, the rear air outlet 16 is connected to the external air source with positive pressure, and the air flows smoothly. The airflow enters the cooling plate 15 through the exhaust pipe 16, and is ejected through the jet slot 1504 and jet head 1503 at the bottom of the cooling plate 15. The jet slot 1504 faces the protective plate 1506. After the airflow hits the jet slot 1504, it moves downward and provides heat dissipation protection for the protective plate 1506. The downward-flowing airflow blows towards the welded position, providing initial cooling. Then, the jet head 1503 further cools the welded position by blowing air, thus increasing the blowing force to ensure uniform cooling of the welded position. Subsequently, the scraper 1501 moves from above the welded area to scrape and clean the residual welding slag. During cleaning, the impurities are pushed by the side slope 1508.Impurities pass through multiple exhaust channels 1507, and some airflow is also discharged through the exhaust channels 1507, thus further cleaning the residue. Simultaneously, the suction pipe 8 is connected to the negative pressure of the external air source, causing the negative pressure to draw the dust collection hood 14 into a negative pressure environment. When impurities move into the dust collection hood 14, the airflow draws them into the dust removal and cooling mechanism 11, and the impurities also enter the external air source dust removal mechanism along the suction pipe 8. This allows for the cleaning and cooling of impurities during the welding process, preventing overheating and damage to components in the air path. It also provides uniform heat dissipation at the welding location, while the dust collection hood 14 protects the heat dissipation area, preventing impurities from splashing during dust removal and reducing leakage. Furthermore, the dust collection hood 14 and the cooling plate 15 are movably connected, ensuring constant contact with the outside of the single pipe 5.

After the height of each set of support components is adjusted, it can accurately limit and support the single pipe and keep it stable. Step 3: Start the moving plate, move the position of the moving plate by the moving motor, and adjust the height of the positioning rod up and down by the drive wheel. At this time, the dust hood and the cooling plate first adhere to the outside of the single pipe, and then continue to push the positioning rod down until the welding head adheres to the opening of the single pipe. Then start the welding mechanism and control the feeding funnel and wire collection coil to send the welding material to the slotted position, and the welding head welds the slotted position. Step 4: Start the gantry. The movable base under the gantry drives the gantry and the welding assembly to move synchronously, thereby welding different positions of the single pipe. During the welding process, the height of the positioning rod is controlled and adjusted by the drive wheel according to the shape of the outer side of the single pipe, so that the welding head is always in contact with the groove position of the single pipe. Step 5: Simultaneously, the rear air outlet is connected to the external air source under positive pressure. The airflow enters the cooling plate through the air outlet and is ejected through the jet slots and jet nozzles at the bottom of the cooling plate. The jet slots face the protective plate. After the airflow hits the jet slots, it moves downward and provides heat dissipation protection for the protective plate. The downward-flowing airflow blows towards the welded position after welding, providing initial cooling. Then, the jet nozzles further cool the welded position by blowing air, thereby increasing the blowing force to facilitate uniform cooling of the welded position. Afterward, the scraper moves from above the welded area to scrape and clean the welding residue remaining in the cooled area. Step Six: Connect the suction pipe to the negative pressure of the external air source, so that the negative pressure draws the dust collection hood into a negative pressure. When the impurities move into the dust collection hood, the airflow will suck the impurities into the dust removal and cooling mechanism, and the impurities will enter the external air source dust removal mechanism through the suction pipe, thereby cleaning the impurities during the welding process.
