[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Example: Figure 1-Figure 13 As shown, the present invention provides a technical solution for auxiliary robotic arm welding equipment for high-rise building steel structures, including an operating structure 2, wherein a position-fixed robotic arm 1 and a welding robotic arm 3 are respectively arranged at both ends of the operating structure 2, and the welding robotic arm 3 includes a double-axis pneumatic cylinder 31 installed on the operating structure 2, two guide rail members 33 connected to the two piston ends of the double-axis pneumatic cylinder 31, two missing gears 34 slidably connected inside the two guide rail members 33, and a multi-directional welding assembly installed inside one of the missing gears 34, and multiple detectors 36 are fixedly installed inside the two missing gears 34.

[0023] Specifically, an anti-skid sleeve 22 for preventing skidding is fixedly sleeved on the outer side of the connecting rod 21, and an installation groove 24 is provided on the outer side of the connecting rod 23 fixedly installed at one end of the connecting rod 21. The double-axis pneumatic cylinder 31 in the welding robot arm 3 is arranged inside the installation groove 24 and is fixedly connected to the connecting rod 23. The other end of the connecting rod 21 is fixedly connected to the U-shaped frame 11 in the position-fixed robot arm 1. The operating structure 2 composed of the connecting rod 21, the anti-skid sleeve 22 and the connecting rod 23 provides convenience for the staff to operate the position-fixed robot arm 1 and the welding robot arm 3.

[0024] Two clamping plates 12 are slidably connected inside the U-shaped frame 11, and the two clamping plates 12 can only move left and right inside the U-shaped frame 11. Support shaft 2 14 and support shaft 13 are provided on the side away from each other of the two clamping plates 12, and multiple mounting seats 15 are rotatably installed on the outer sides of support shaft 13 and support shaft 2 14, and the mounting seats 15 are fixedly connected to the adjacent clamping plates 12. Support shaft 13 and support shaft 2 14 can rotate, but the relative positions between support shaft 13 and support shaft 2 14 and clamping plate 12 remain unchanged.

[0025] A plurality of guide grooves 120 are provided on both sides of the U-shaped frame 11. Two rotating plates 16 and two rotating plates 3 18 are rotatably sleeved on the outer side of the support shaft 13. A connecting frame 6 121 is fixedly connected between the two rotating plates 16. Two ends of the U-shaped connecting frame 6 121 pass through two of the guide grooves 120. The connecting frame 6 121 moves horizontally on the U-shaped frame 11 through the guide grooves 120. A connecting frame 110 is fixedly connected between the two rotating plates 18. Two ends of the U-shaped connecting frame 110 pass through two of the guide grooves 120. 110 moves horizontally on the U-shaped frame 11 through the guide groove 120; and because two rotating plates 2 17 and two rotating plates 4 19 are rotatably sleeved on the outer side of the support shaft 2 14, a connecting frame 2 111 is rotatably connected between the two rotating plates 2 17, and the two ends of the U-shaped connecting frame 2 111 pass through two of the guide grooves 120, and a connecting frame 3 112 is rotatably connected between the two rotating plates 4 19, and the U-shaped connecting frame 3 112 passes through two of the guide grooves 120, and the connecting frame 2 111 and the connecting frame 3 112 are slidably connected between the connecting frame 2 111.

[0026] Two connecting frames eight 123 are fixedly connected between connecting frame six 121 and connecting frame two 111, so connecting frame six 121 and connecting frame two 111 move synchronously, and when clamping plate one 12 can only move left and right, rotating plate one 16 and rotating plate two 17 rotate synchronously; connecting frame seven 122 is fixedly connected between connecting frame one 110 and connecting frame three 112, connecting frame one 110 and connecting frame three 112 move synchronously, and rotating plate three 18 and rotating plate four 19 rotate synchronously.

[0027] A connecting frame 4 113 is fixedly installed on one side of the connecting frame 3 112, and a pneumatic cylinder 1 14 is fixedly installed on one side of the connecting frame 4 113. The pneumatic cylinder 1 14 is fixedly connected to the U-shaped frame 1 11. A connecting frame 5 115 is fixedly installed on one side of the connecting frame 6 121, and a pneumatic cylinder 2 116 is fixedly connected to one side of the connecting frame 5 115. The pneumatic cylinder 2 116 is fixedly connected to the U-shaped frame 1 11. When the pneumatic cylinder 1 14 and the pneumatic cylinder 2 116 are extended synchronously, the pneumatic cylinder 1 14 pushes the connecting frame 3 112 and the connecting frame 1 through the connecting frame 4 113. 110 moves forward synchronously, and the pneumatic cylinder 116 pushes the connecting frame 6 121 and the connecting frame 2 111 to move backward synchronously through the connecting frame 5 115, so that the rotating plate 16 and the rotating plate 3 18 on the outside of the support shaft 13 enter the open state, and the rotating plate 2 17 and the rotating plate 4 19 on the outside of the support shaft 2 14 enter the open state, and the clamping plate 12 moves to a position away from the middle of the inner cavity of the U-shaped frame 11, and the two clamping plates 12 move away from each other; similarly, after the pneumatic cylinder 114 and the pneumatic cylinder 2 116 are controlled to shrink synchronously, the two clamping plates 12 move closer to each other.

[0028] A battery 5 is fixedly installed on one side of a protective shell 118, and an equipment installation structure 4 is set on the other side of the protective shell 118. In the equipment installation structure 4, a ring 1 41 and a ring 2 42 are fixedly installed on one side of the protective shell 118, and two arc-shaped vertical plates 43 are fixedly installed between the ring 1 41 and the ring 2 42. The user can place the welding gas supply equipment inside the support frame composed of the ring 1 41, the ring 2 42 and the two arc-shaped vertical plates 43, and the two arc-shaped vertical plates 43 are respectively provided with a clamping plate 2 44 on the opposite side, and one side of the clamping plate 2 44 is rotated to connect Bolts 45 and short shafts 46 are connected, and both bolts 45 and short shafts 46 are penetrated on the arc-shaped vertical plate 43. Under the limitation of bolts 45 and short shafts 46, clamping plate 44 can only move horizontally. The two bolts 45 threadedly connected by the two arc-shaped vertical plates 43 are rotated, and the bolts 45 push the clamping plate 44 to move, so that the clamping plate 44 clamps and fixes the welding gas supply equipment. The welding gas supply equipment can be pre-installed together with the position-fixed mechanical arm 1, so that the welding gas supply equipment and the battery 5 are respectively provided on both sides of the U-shaped frame 11, so that the weight on both sides of the position-fixed mechanical arm 1 is balanced.

[0029] In the present application, the welding device composed of the position-fixing mechanical arm 1, the operating structure 2 and the welding mechanical arm 3 is used in the following specific method: Since multiple operation buttons are installed on the battery 5, after pressing the operation button electrically connected to the double-axis pneumatic cylinder 31, the double-axis pneumatic cylinder 31 works, and the two transmission plate members 32 fixedly installed at both piston ends of the double-axis pneumatic cylinder 31 move away from each other, and the two transmission plate members 32 are respectively fixedly connected to the two guide rail members 33, so the two guide rail members 33 move away from each other, so that the guide rail formed by the two guide rail members 33 is in an open state.

[0030] Then, holding the connecting rod 21, the two guide rails 33 and the U-shaped frame 11 are sleeved to the outside of the steel structure, and the positions of the two guide rails 33 are controlled so that they are located near the position of the steel structure to be welded.

[0031] Subsequently, the operating button on the battery 5 electrically connected to the two pneumatic cylinders 114 and the two pneumatic cylinders 2 116 is pressed, so that the two pneumatic cylinders 114 and the two pneumatic cylinders 2 116 in the fixed position robot arm 1 work and contract, so that the two clamping plates 12 are close to each other, and finally the two clamping plates 12 are clamped to the two sides of the steel structure, and the air pressure sensor 117 fixedly installed on the top of one of the pneumatic cylinders 114 monitors the internal air pressure value of the pneumatic cylinder 114. When the internal air pressure value of the pneumatic cylinder 114 reaches a preset value, the two pneumatic cylinders 114 electrically connected to the air pressure sensor 117 are retracted. The pressure cylinder 114 and the two pneumatic cylinders 116 stop working. At the same time, an alarm 119 fixedly installed on one side of one of the protective shells 118 is electrically connected to the air pressure sensor 117. At this time, the alarm 119 works and sounds an alarm to remind the staff to release the welding equipment away from the welding position to reduce safety hazards. The position-fixed mechanical arm 1 composed of a U-shaped frame 11, two clamping plates 12, two pneumatic cylinders 114, two pneumatic cylinders 116 and other structures can fix the welding equipment on different steel structures to ensure the adaptability of the welding equipment during high-altitude construction.

[0032] Subsequently, the ground staff remotely controls the dual-axis pneumatic cylinder 31 in the welding robot arm 3 to work and retract (installing a wireless communication module on the welding equipment to communicate with the ground equipment and connecting a pipeline system between the welding gas supply equipment and the welding gun 321 are both applications of public technologies and are not described in detail here), and the two guide rail members 33 approach each other, so that the two guide rail members 33 enter a merged state. Since arc-shaped guide rods 35 are fixedly installed on both sides of the missing gear 34 inside the guide rail member 33, the missing gear 34 and the arc-shaped guide rod 35 are both arranged inside the guide rail member 33. After the two guide rail members 33 are merged, the two missing gears 34 form a complete gear, and the gear can rotate inside the guide rail formed by the two guide rail members 33, and the arc-shaped guide rod 35 and the guide rail member 33 are in an interference fit state. Before the missing gear 34 is subjected to a certain force, the missing gear 34 will not rotate.

[0033] Subsequently, the forward and reverse motor 1 39 is controlled to rotate forward for a period of time and then reverse for a period of time. Since the shell of the forward and reverse motor 1 39 is fixed together with the mounting base 2 310 fixedly installed on the top of the guide rail member 33, the working forward and reverse motor 1 39 drives the transmission gear 38 fixedly mounted on the output end to rotate, and the transmission gear 38 partially penetrates the reserved groove 37 opened on the top of the guide rail member 33 and then engages with the missing gear 34. The rotating transmission gear 38 drives the gear to rotate. When the forward and reverse motor 1 39 is working at this time, the gear rotates 90° and then resets. During this process, the multiple detectors 36 fixedly installed inside the two missing gears 34 rotate 90°, and the multiple detectors 36 collect three-dimensional data of the steel structure, and the three-dimensional data is fed back to the ground equipment by the detectors 36.

[0034] Subsequently, the device builds a three-dimensional model of the steel structure to be welded based on the data collected by the detector 36. Subsequently, the pre-trained model inside the device controls the operation of the multi-directional welding assembly, and the multi-directional welding assembly performs welding processing on the steel structure. The details of the operation of the multi-directional welding assembly are as follows: The mounting seat 311 in the multi-directional welding assembly is fixedly installed inside one of the missing gears 34, and the transmission horizontal shaft 314 rotatably penetrated on the mounting seat 311 can rotate by itself. Two pneumatic cylinders 4 313 are fixedly installed on both sides of the mounting seat 4 312 fixedly installed outside the transmission horizontal shaft 314, and a welding gun 321 is fixedly installed between the two pneumatic cylinders 4 313. Controlling the operation of the pneumatic cylinder 4 313 can control the distance between the welding gun 321 and the missing gear 34; A brake 315 and a driving gear 316 are respectively sleeved on both ends of the outer side of the transmission horizontal shaft 314, and the driving gear 316 is fixedly connected to the transmission horizontal shaft 314. A transmission plate 2 319 and a sliding frame 320 are fixedly installed on the outer side of the rack 317 engaged with the driving gear 316. A pneumatic cylinder 318 is fixedly connected to one side of the transmission plate 2 319 and is fixedly connected to the mounting seat 3 311. The sliding frame 320 penetrates the mounting seat 311. Under the support of the sliding frame 320 and the pneumatic cylinder 318, the rack 317 can perform reciprocating horizontal motion; When the pneumatic cylinder three 318 is controlled to work, the pneumatic cylinder three 318 drives the rack 317 to move through the transmission plate two 319, and the rack 317 drives the transmission horizontal shaft 314 to rotate through the meshing drive gear 316. The transmission horizontal shaft 314 drives the two pneumatic cylinders four 313 and the welding gun 321 fixedly installed by the two pneumatic cylinders four 313 to rotate through the mounting seat four 312. By controlling the pneumatic cylinder three 318 to extend or contract, the welding gun 321 can be rotated in different directions at the position of the transmission horizontal shaft 314, so that the welding gun 321 faces different directions to meet the welding needs of welding positions at different angles. After controlling the welding gun 321 to face the steel structure to be welded, the pneumatic cylinder four 313 is controlled to work to push the welding gun 321 to move, so that the distance between the muzzle of the welding gun 321 and the steel structure to be welded reaches a preset distance.

[0035] Subsequently, the forward and reverse motor 39 is controlled to work, so that the forward and reverse motor 39 rotates forward for a period of time, and the forward and reverse motor 39 stops working after the gear rotates forward 180°. During this process, the welding gun 321 works to weld the steel structure, and the pneumatic cylinder 4 313 extends or contracts to control the distance between the welding gun 321 and the steel structure to ensure that the distance between the muzzle of the welding gun 321 and the welding position of the steel structure always maintains a preset distance.

[0036] Subsequently, the forward and reverse motor 39 is controlled to work in reverse for a period of time to make the gear rotate 360° in the opposite direction. During this process, when the vehicle rotates 180° in the opposite direction, the welding gun 321 and the pneumatic cylinder 313 cooperate to complete the welding of the steel structure. The welding robot arm 3 composed of two guide rails 33, two missing gears 34, a multi-directional welding assembly, a dual-axis pneumatic cylinder 31 and other structures cooperates with the ground equipment to automatically complete the welding of steel structures of various shapes, reduce the difficulty of high-altitude construction for workers, and reduce the safety hazards of high-altitude steel structure welding construction.

[0037] And the brake 315 is fixedly connected to the missing gear 34. Before the pneumatic cylinder 318 works, the brake 315 stops working and the transmission horizontal axis 314 loses its limit. After the brake 315 completes its work, the brake 315 works to limit the transmission horizontal axis 314 to ensure the stability of the work after the angle adjustment of the welding gun 321 is completed.

[0038] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
