Description

Technical Field

[0001] This invention relates to the field of automatic welding technology, and in particular to an automatic welding device for the production of standard sections of tower cranes. Background Technology

[0002] Currently, standard tower crane sections play an important role in mechanical equipment such as cranes, tower cars, and elevators. A good standard section can not only improve the stability of these heavy machines, but also enhance the overall safety performance of the machine.

[0003] When processing tower crane standard sections, the various components of the tower crane standard section are usually welded to increase the stability of the tower crane standard section. In the existing technology, when welding tower crane standard sections, a handling robot arm and a welding machine are usually used together to perform welding. That is, the handling robot arm is used to move the components of the tower base standard section, place them on the welding machine, and perform welding.

[0004] In the existing technology, when using the automatic welding device for tower base standard sections, there is no device for inspecting the welded parts. After the tower base standard section is welded, it needs to be moved to another inspection device for inspection. If a problem is found in the welded part, it needs to be placed back on the automatic welding device for repair welding. The above inspection and repair welding operations are cumbersome, which affects the welding efficiency of the automatic welding device, thereby reducing the production efficiency of the manufacturer and causing certain economic losses to the manufacturer. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic welding device for the production of tower crane standard sections. This device can inspect the welded parts and the outer surface of the tower crane standard sections during welding using a video inspection system. Furthermore, it can perform repair welding on the tower crane standard sections during the welding process using a repair welding component. This reduces the number of defective tower crane standard sections during production, increases the yield rate of tower crane standard sections, and thus largely avoids damage to the tower crane standard sections during use, which could lead to safety accidents.

[0006] To achieve the above objectives, the present invention provides an automatic welding device for the production of standard tower crane sections, comprising a transport robotic arm, a slide rail, and a welding machine.

[0032] Next, with reference to the accompanying drawings, the detailed implementation manners of the present invention will be described in detail, but it should be understood that the protection scope of the present invention is not limited by the detailed implementation manners.

[0033] Unless otherwise clearly stated, throughout the specification and claims, the term "comprise" or its variations such as "comprises" or "including" etc. will be understood to include the stated elements or components, without excluding other elements or other components.

[0034] Refer Figures 1-9As shown, an automatic welding device for the production of tower crane standard sections according to an embodiment of the present invention includes a handling robotic arm 1, a slide rail 2, and a welding machine table 3. The handling robotic arm 1 is slidably connected to the upper end of the slide rail 2. By sliding the handling robotic arm 1, its position can be adjusted on the slide rail 2, so as to facilitate placing the tower base standard section components on the welding machine table 3, and then the welding machine table 3 welds the tower base standard section components. The welding machine table 3 is located on one side of the handling robotic arm 1. The welding machine table 3 and the handling robotic arm 1 cooperate. First, the handling robotic arm 1 first clamps the tower base standard section main body on the welding machine table 3, and then contacts other components with the tower base standard section main body, and then welding is performed by the welding machine table 3.

[0035] Among them, the welding machine table 3 includes a base 301, a pair of main columns 302, a fixing frame 303, and a stabilizing block 304. The stabilizing block 304 is fixedly connected to the lower end of the base 301. The stabilizing block 304 can specifically be a shock-absorbing block or an anti-slip block, which can increase the stability of the automatic welding device. The stabilizing block 304 can also be a lifting rod that can be lifted. Through the lifting rod, the height of the automatic welding device can be increased, so as to facilitate different workers to adapt to the automatic welding device, and thus facilitate the workers to touch up the paint on the tower base standard section. A pair of main columns 302 are fixedly connected to the upper end of the base 301. The fixing frame 303 is located between the pair of main columns 302. A fixed shaft and a rotating shaft are provided between the main columns 302 and the fixing frame 303, that is, the fixing frame 303 is rotatably connected between the pair of main columns 302.

[0036] Specifically, the fixing frame 303 is rotatably connected between the pair of main columns 302, which can facilitate adjusting the position of the fixing frame 303, that is, can adjust the position of the tower base standard section installed on the fixing frame 303, so as to facilitate the handling robotic arm 1 to place the tower base standard section and facilitate the welding machine table 3 to weld the tower base standard section.

[0037] See Figures 1-4 As shown, a plurality of chip leakage holes 3011 are provided on the base 301. A dust collection box 12 matching the chip leakage holes 3011 is installed at the lower end of the base 301. The dust collection box 12 can collect the falling impurities. The impurities can enter the interior of the dust collection box 12 through the base 301, which is convenient for cleaning the automatic welding device.

[0038] The automatic welding device for the production of tower crane standard sections further includes a video detection system, a cleaning robotic arm 10, and a support arm 5. The video detection system is used to detect the welded part of the tower base standard section and the appearance of the tower base standard section. The support arm 5 is used to perform repair welding on the tower base standard section. The cleaning robotic arm 10 is used to clean the tower base standard section before the repair welding of the tower base standard section. The cleaning robotic arm 10 is used to clean the sundries on the tower base standard section and can also polish the tower base standard section, so as to improve the quality of the repair welding by the support arm 5.

[0039] Specifically, see Figure 7 As shown in the figure, the video detection system is used to detect the welds of the standard sections of the tower base and the exterior of the standard sections of the tower base. When the video detection system detects that the welds of the standard sections of the tower base are not standard, the standard sections of the tower base need to be repaired by welding. At the same time, it can also detect the paint surface of the exterior of the standard sections of the tower base. If the paint surface is damaged, it can also remind the staff, and the staff can use a touch-up pen to perform touch-up operations.

[0040] Preferably, a paint touch-up mechanism matching the video detection system can also be set. When the video detection system detects that there is paint damage at a certain place on the exterior of the standard section of the tower base, the paint touch-up mechanism and the video detection system cooperate to be able to complete the touch-up of the paint surface. Specifically, the paint touch-up method can be various paint touch-up methods such as spraying or using a touch-up pen, and it only needs to fill in the damaged place of the paint surface.

[0041] Refer Figures 1-2 As shown in the figure, the video detection system includes eight camera devices 4. A plurality of grooves 3031 matching the camera devices 4 are provided on the fixing frame 303. The camera devices 4 are installed in the grooves 3031, and a transparent protective cover can also be provided on the grooves 3031 to protect the camera devices 4. The eight camera devices 4 are all installed on the welding machine table 3. Four camera devices 4 are in a group, and the two groups of camera devices 4 are arranged oppositely. The two groups of camera devices 4 can take pictures of the standard sections of the tower base without dead angles. The camera devices 4 transmit the captured videos to the cloud server. Through the cloud server, the captured data is analyzed to generate a solution, and the solution is transmitted to the support arm 5 through the Internet of Things module. The support arm 5 operates according to the generated solution, and the support arm 5 can repair the welds of the standard sections of the tower base.

[0042] Refer Figures 1-6 As shown in the figure, the support arm 5 is rotatably connected to the fixed shaft, that is, the support arm 5 is rotatably connected to the welding machine table 3. The support arm 5 is driven by a rotation motor. The rotation motor is matched with the video detection system, and the solution generated by the cloud server also includes the rotation motor, which drives the rotation motor to rotate to the corresponding position. The support arm 5 rotates along the outer edge of the fixing frame 303. During the rotation process, the position of the welding repair component 6 can be changed, so that the welding repair component 6 can repair the positions of the standard sections of the tower base that need to be repaired by welding.

[0043] Specifically, the welding repair component 6 is installed at the lower end of the support arm 5. The welding repair component 6 can slide at the lower end of the support arm 5. Through the slidable welding repair component 6, the welding repair component 6 can slide to any position, so that the function of the welding repair component 6 to repair different positions on the standard sections of the tower base can be realized.

[0044] Refer Figure 6As shown, the repair welding component 6 includes an electric slider 601 and a repair welding head 604. The repair welding head 604 is used for repair welding, and the electric slider 601 is used to slide on the support arm 5. Specifically, a chute matching the electric slider 601 is provided on the support arm 5, and the repair welding head 604 is slidably connected in the chute through the electric slider 601. The specific model of the electric slider 601 can be: MSC7M.

[0045] Specifically, referring Figure 6 As shown, a rotating arm 602 is installed between the electric slider 601 and the repair welding head 604. The rotating arm 602 can rotate the repair welding head 604 to make the repair welding head 604 rotate 360° around the rotating arm 602 as the axis. A telescopic rod 603 is installed between the rotating arm 602 and the repair welding head 604. By the telescopic rod 603, the position of the repair welding head 604 can be changed. That is, the repair welding head 604 can be made to approach the tower base standard section through the telescopic rod 603, or the repair welding head 604 can be made to move away from the tower base standard section through the telescopic rod 603. At the same time, the force used for welding by the repair welding head 604 can also be changed through the telescopic rod 603, so as to better perform repair welding on the tower base standard section.

[0046] Furthermore, referring Figure 6 As shown, a first suction groove 6041 is provided on the repair welding head 604. A repair welding tip is provided on the repair welding head 604. The first suction groove 6041 is arranged along one circle of the repair welding tip. When the repair welding tip performs repair welding, inert gas can be ejected inside the repair welding head 604 to form a shielded weld, thereby reducing spatter, and at the same time, the quality of welding can also be improved, and the crack resistance of the weld seam can be increased.

[0047] Referring Figures 1-6 As shown, an air inlet pipe 7 matching the first suction groove 6041 is fixedly connected to the repair welding head 604. The air inlet pipe 7 is communicated with the first suction groove 6041. One end of the air inlet pipe 7 far from the repair welding head 604 is communicated with an inert gas tank. During the process of repair welding, the inert gas in the inert gas tank sequentially passes through the air inlet pipe 7 and the first suction groove 6041 and is ejected. Among them, the inert gas in the inert gas tank can be one of argon, helium and carbon dioxide gas.

[0048] Preferably, a plurality of through holes may be formed in the repair welding head 604. The through holes are connected to a gas recovery system which can recover the gas ejected from the first air suction groove 6041 and the spattered welding slag generated during the welding process, and suck in the gas, thereby preventing an excessive amount of a certain inert gas in the current space and causing discomfort to the staff in the current space. At the same time, it can also collect and process the spattered welding slag. Among them, the through holes are arranged along the outside of the first air suction groove 6041. By setting through holes of different specifications and sizes, it is not easy to cause the situation of welding slag blockage during the gas recovery process. After the gas is recovered, it can also be filtered and the gas can be recycled.

[0049] In addition, during the detection process of the video detection system, it can only detect the current shooting situation. For example, if there is a welding joint that is not welded well, it may be misjudged through the misaligned shooting of the video detection system. At the same time, for the paint surface of the tower base standard section, misjudgment may also occur due to misalignment. For the paint surface that is easy to fall off on the tower base standard surface, it is not easy to fall off without cleaning, and it is not easy to detect only through the video detection system. Therefore, before the video detection system is used for detection, it is also necessary to clean the outer surface of the tower base standard section through the cooperation of the cleaning robot arm 10 and the first cleaning component 8, so as to reduce the situation of affecting the judgment result due to the shooting angle problem.

[0050] Specifically, as shown in Figures 1-4 figures, the cleaning robot arm 10 is fixedly connected to the main column 302, that is, the cleaning robot arm 10 is installed on the welding machine table 3. Generally, the cleaning robot arm 10 is fixedly connected to the main column 302 by welding, which increases the stability of the tower base standard section to a certain extent. It can also be fixed by bolts, plugging, etc., which is convenient for disassembling the cleaning robot arm 10. When the cleaning robot arm 10 is damaged, it is convenient to replace the cleaning robot arm 10. Among them, the cleaning robot arm 10 can enter the inside of the fixing frame 303 and clean the tower base standard section. The cleaning robot arm 10 sequentially passes through the inside of the tower base standard section, and then cleans the welding joints and the outer surface of the tower base standard section. During the cleaning process, it can clean the paint surface of the outer surface of the tower base standard section, and clean the places where the paint surface of the tower base standard section peels off. It is detected by the video detection system and then a reminder is given. When there is peeling at the welding joint of the tower base standard section, the cleaning robot arm 10 can also clean the peeling place. Thus, it is convenient for the video detection system to take pictures and detect.

[0051] As shown in Figures 1 to 7As shown, the cleaning robotic arm 10 is matched with the video detection system. After the cleaning robotic arm 10 finishes cleaning the tower base standard section, the video detection system then takes pictures for detection. Among them, the cleaning robotic arm 10 includes a robotic arm main body 1001 and a second cleaning seat 1002. The robotic arm main body 1001 is used to adjust the position where the second cleaning seat 1002 is located, so that the second cleaning seat 1002 cleans at different positions of the tower base standard section. The robotic arm main body 1001 can also move the second cleaning seat 1002 back and forth, so as to achieve deep cleaning of a certain part of the tower base standard section by the second cleaning seat 1002.

[0052] Specifically, refer Figure 7 As shown, a pair of third suction grooves 10021 are formed on the second cleaning seat 1002. A second cleaning brush 1003 is fixedly connected between the pair of third suction grooves 10021. The tower base standard section can be cleaned by the second cleaning brush 1003. A second dust suction pipe 11 matched with the third suction groove 10021 is fixedly connected to the second cleaning seat 1002. An air pump is arranged at one end of the second dust suction pipe 11 away from the second cleaning seat 1002. The second dust suction pipe 11 is communicated with the third suction groove 10021. When the second cleaning brush 1003 cleans the tower base standard section, the air pump is started simultaneously, and air is sucked into the air pump through the third suction groove 10021. The dust and paint residues cleaned by the second cleaning brush 1003 during the cleaning process are sucked in through the third suction groove 10021, reducing the situation that impurities are generated and fall on other positions of the tower base standard section during the cleaning process.

[0053] Among them, the second cleaning brush 1003 can combine the grinding sheet and the cleaning wire, and the grinding sheet and the cleaning wire can be switched. When cleaning is required, the cleaning wire is switched for use. When grinding is required, the grinding sheet is switched for use. The grinding sheet and the cleaning wire are integrated and are rotationally connected to the second cleaning seat 1002 through a motor. It can both grind and clean by rotating, and can also grind and clean by reciprocating. It can also reciprocate while the second cleaning brush 1003 is rotating, which can improve the grinding and cleaning efficiency to a certain extent.

[0054] Refer [[ID=I2]] Figures 1-4 As shown, the automatic welding device for tower crane standard section production further includes a first cleaning component 8. The first cleaning component 8 is installed outside the fixing frame 303. The first cleaning component 8 can clean the four sides of the outside of the tower base standard section at the same time. That is, the cleaning robotic arm 10 is used to clean the inner surface of the tower base standard section, and the first cleaning component 8 is used to clean the outer surface of the tower base standard section.

[0055] Specifically, refer Figures 1-4As shown in the figure, a plurality of mounting blocks are fixedly connected to the fixing frame 303. A sliding rod is arranged between the mounting blocks, and a first cleaning component 8 is slidably connected to the sliding rod. Among them, two sliding rods are installed between one mounting block, and one of the sliding rods is a threaded rod driven by a motor. The first cleaning component 8 is matched with the threaded rod. When the threaded rod is driven by the motor to rotate, the first cleaning component 8 rotates along with the threaded rod. Then, the first cleaning component 8 contacts the outer surface of the tower base standard surface, and can clean the outer surface of the tower base standard section. Among them, one first cleaning component 8 can clean one side of the tower base standard section, and one first cleaning component 8 corresponds to one motor, which is convenient for the first cleaning component 8 to operate differently.

[0056] As shown Figure 8 As shown in the figure, a dust suction component 9 is installed on the first cleaning component 8. The dust suction component 9 is used to adsorb the impurities cleaned by the first cleaning component 8. Among them, the first cleaning component 8 includes a first cleaning seat 801. A pair of second suction grooves 8011 are opened on the first cleaning seat 801. A first cleaning brush 802 is arranged between the pair of second suction grooves 8011. The first cleaning brush 802 can clean the outside of the tower base standard section. The impurities cleaned are adsorbed by the dust suction component 9 and then filtered, and the filtered residues can be reused.

[0057] Among them, the dust suction component 9 is connected to the second dust suction pipe 11. That is, the residues cleaned by the second dust suction pipe 11 can be filtered in the dust suction component 9. After the filtration is completed, they can be separated from dust and metal chips. The metal chips can be collected and reused.

[0058] Preferably, the first cleaning brush 802 and the second cleaning brush 1003 can be brushes with induction devices. Through the induction devices at the top of the brushes, the current paint surface state of the tower base standard section and the state at the welded seams can be sensed, which is matched with the video detection system. The data sensed by the induction devices is also transmitted to the cloud for analysis and then transmitted to the support arm 5. The support arm 5 and the repair welding component 6 perform repair welding operations according to the returned data.

[0059] As shown Figures 1-9 As shown in the figure, the dust suction component 9 includes a first dust suction pipe 901, a filter box 902 and a first connecting pipe 903. The first dust suction pipe 901 is communicated with the second suction groove 8011. The impurities cleaned by the first cleaning component 8 enter the filter box 902 through the second suction groove 8011 for filtration. The filter box 902 is located between the first connecting pipe 903 and the first dust suction pipe 901. A second connecting pipe 904 is arranged between the first connecting pipe 903 and the filter box 902.

[0060] Specifically, as shown Figure 9As shown, the filter box 902 includes a box body 9021. A plurality of electromagnetic adsorption plates 9022 are provided on the inner wall of the box body 9021. When the electromagnetic adsorption plates 9022 are opened, the electromagnetic adsorption plates 9022 can adsorb metal fragments, and then the non-metal fragments can be taken out, so that the separation of metal fragments and non-metal fragments can be achieved.

[0061] Furthermore, a filter plate 9023 matching the second connecting pipe 904 is provided in the filter box 902. A second limiting block 9026 is provided at the lower end of the filter plate 9023. The second limiting block 9026 can hold the filter plate 9023, and the second limiting block 9026 enables the filter plate 9023 to fit with the second connecting pipe 904. When the first connecting pipe 903 is started, the residues inhaled through the first dust suction pipe 901 and the filter box 902 can be blocked by the filter plate 9023, so that impurities are not easily introduced into the interior of the first connecting pipe 903, thereby improving the service life of the first connecting pipe 903. A sealing door 9024 is provided at the lower end of the box body 9021. The impurities in the filter box 902 can be taken out through the sealing door 9024. An inclined bottom wall 90211 matching the sealing door 9024 is provided on the inner wall of the filter box 902. One end of the inclined bottom wall 90211 close to the sealing door 9024 is lower than the end of the inclined bottom wall 90211 far from the sealing door 9024. That is, after the impurities fall into the filter box 902, most of them will accumulate at the sealing door 9024, which is convenient for taking out the impurities in the filter box 902.

[0062] Among them, the filter plate 9023 is detachable, that is, the filter plate 9023 can be replaced.

[0063] See Figure 9 As shown, a first limiting block 9025 matching the sealing door 9024 is provided on the box body 9021. The first limiting block 9025 can hold the sealing door 9024, so that the sealing door 9024 seals the filter box 902, and impurities are not easily run out of the filter box 902.

[0064] During use, first install the main components of the tower base standard section on the fixing frame 303, and then use the handling robotic arm No. 1 to bring other components of the tower base standard section into contact with the main components, and perform welding through the welding machine platform No. 3. After welding is completed, use the handling robotic arm No. 1 to carry other components of the tower base standard section, and repeat the current operation until the tower base standard section is welded.

[0065] During the welding process, the video inspection system captures video of the tower base standard section, which is then analyzed by a cloud server. The welding repair component 6 on the support arm 5 performs welding based on the data analyzed by the cloud server. During the welding process, inert gas is supplied through the air intake pipe 7, forming a protective gas that increases the quality of the welding and reduces spatter. Before the video inspection system performs its inspection, the cleaning robotic arm 10 and the first cleaning component 8 work together to clean the exterior of the tower base standard section, removing peeling paint. During the cleaning process, the dust suction component 9 absorbs the removed impurities, reducing the amount of debris falling to the ground or other parts of the tower base standard section. The dust suction component 9 can also filter both metallic and non-metallic debris.

[0066] The cleaning robotic arm 10 cleans the interior of the tower base standard section, while the first cleaning component 8 cleans the exterior of the tower base standard section. If debris falls to the lower end of the welding machine 3, it can eventually enter the dust collection box 12 through the chip leakage hole 3011 for temporary collection, thus reducing the time wasted in cleaning the welding machine 3.
