[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0019] In the description of the present invention, it should be understood that terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “top”, “bottom”, “inside” and “outside” indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0020] like Figure 1-Figure 10 As shown, an embodiment of the present invention proposes a welding auxiliary device for assisting in welding electric steel poles, the structure of which includes a plate positioning and splicing assembly 100, a welding movable kit 200 and a plate conveying assembly 300, wherein the plate conveying assembly 300 is arranged on one side of the plate positioning and splicing assembly 100, and the welding movable kit 200 is arranged above the plate positioning and splicing assembly 100, the plate positioning and splicing assembly 100 is used to splice two plates together and align the edges so that the longer sides of the two plates are fitted together, the welding movable kit 200 is used to assist the welding gun to align above the two plates for welding, and the plate conveying assembly 300 is used to transport the plates to the plate positioning and splicing assembly 100 in sequence.

[0021] The specific structure of the plate positioning and splicing assembly 100 proposed in this embodiment includes a first supporting arm 101, a second supporting arm 102 and a central rotating shaft 103. The first supporting arm 101 and the second supporting arm 102 are arranged on the central rotating shaft 103. The first supporting arm 101 and the second supporting arm 102 are both rotatably connected to the central rotating shaft 103. The rotation axes of the first supporting arm 101 and the second supporting arm 102 coincide with each other. The angle opening formed by the first supporting arm 101 and the second supporting arm 102 is always in the plane where the central rotating shaft 103 is located. Above the first supporting arm 101 and the second supporting arm 102 are both rotatably arranged on the central rotating shaft 103, and the angle between the first supporting arm 101 and the second supporting arm 102 is adjustable, which can be adjusted according to welding requirements during use. For example, when welding a hexagonal cylindrical steel rod formed by 6 plates, the angle between the first supporting arm 101 and the second supporting arm 102 is adjusted to 60 degrees, and then the two plates are respectively fixed on the first supporting arm 101 and the second supporting arm 102, and the welding mobile kit 200 can weld the two plates.

[0022] By setting a rotating first supporting arm 101 and a second supporting arm 102 to fix the plate, the angle between the first supporting arm 101 and the second supporting arm 102 is flexibly adjusted according to welding requirements, and the two plates are spliced ​​together at a specific angle to facilitate welding, thereby ensuring the straightness of the weld, thereby improving the verticality of the power steel pole after welding, and improving the structural strength of the power steel pole.

[0023] When this embodiment is used, firstly, the angle between the first carrying arm 101 and the second carrying arm 102 is adjusted according to the shape of the target steel rod, and then the angle between the first carrying arm 101 and the second carrying arm 102 is fixed.

[0024] Then the first carrying arm 101 is rotated to a horizontal position, and the first plate is conveyed to the first carrying arm 101 through the plate conveying assembly 300. Then the first carrying arm 101 and the second carrying arm 102 are synchronously rotated on the central rotating shaft 103. During the rotation, the end of the first carrying arm 101 is gradually lifted, and the end of the second carrying arm 102 is gradually lowered. During the rotation, the first plate slides from the first carrying arm 101 to the second carrying arm 102 due to its own gravity, and then the second carrying arm 102 fixes the first plate on the second carrying arm 102.

[0025] Then, the first carrying arm 101 and the second carrying arm 102 rotate synchronously in opposite directions on the central rotating shaft 103 until the first carrying arm 101 returns to the horizontal position. At this time, the sheet conveying assembly 300 conveys the second sheet to the first carrying arm 101. In this embodiment, the two plates to be welded are placed on the first bearing arm 101 and the second bearing arm 102 respectively, and the first bearing arm 101 is kept horizontal and the second bearing arm 102 is kept inclined during welding. The plate on the second bearing arm 102 is pressed on the plate on the first bearing arm 101 due to its own gravity, so that the edges of the two plates are in close contact, thereby avoiding defects such as overhead and virtual joints in the weld during welding, which will affect the structural strength of the power steel pole.

[0026] The plate positioning and splicing assembly 100 proposed in this embodiment also includes a rotating servo motor 104 and a rotating shaft bracket 119. The central rotating shaft 103 is rotatably arranged on the rotating shaft bracket 119. A fastening buckle 118 is provided on the central rotating shaft 103. The fastening buckle 118 is configured to lock the angle between the first supporting arm 101 and the second supporting arm 102. The output end of the rotating servo motor 104 is connected to the central rotating shaft 103. The rotating servo motor 104 is configured to drive the central rotating shaft 103 to rotate. The fastening buckle 118 locks the first supporting arm 101 and the second supporting arm 102 on the central rotating shaft 103, thereby realizing the locking of the angle between the first supporting arm 101 and the second supporting arm 102. Therefore, when the rotating servo motor 104 drives the central rotating shaft 103 to rotate, the first supporting arm 101 and the second supporting arm 102 rotate synchronously with the central rotating shaft 103.

[0027] When this embodiment is in use, after adjusting the angle between the first bearing arm 101 and the second bearing arm 102 according to the shape of the target steel rod, the fastening buckle 118 is used to fix the angle between the first bearing arm 101 and the second bearing arm 102, and at the same time, the first bearing arm 101 and the second bearing arm 102 are fixed on the central rotating shaft 103.

[0028] Then, the servo motor 104 is rotated to drive the central shaft 103 to rotate, and the central shaft 103 synchronously drives the first carrying arm 101 and the second carrying arm 102 to rotate. When the first carrying arm 101 rotates to a horizontal position, the servo motor 104 stops working, and then the plate conveying assembly 300 conveys the first plate to the first carrying arm 101, and then the servo motor 104 is rotated to drive the central shaft 103 to rotate, so that the end of the first carrying arm 101 gradually rises and the end of the second carrying arm 102 gradually drops. After the first plate slides onto the second carrying arm 102, the servo motor 104 is rotated to drive the central shaft 103 to rotate in the opposite direction until the first carrying arm 101 returns to a horizontal position, and then the second plate can be conveyed to the first carrying arm 101, and the two plates can be welded.

[0029] In this embodiment, a fastening buckle 118 is provided to lock the first supporting arm 101 and the second supporting arm 102 to avoid changes in the angle between the first supporting arm 101 and the second supporting arm 102 during the welding process, thereby improving the structural stability of the plate positioning and splicing assembly 100. At the same time, a rotating servo motor 104 is used to drive the rotation of the central rotating shaft 103, and the rotation speed and rotation direction of the central rotating shaft 103 can be adjusted, so that the plate can slide smoothly on the first supporting arm 101 and the second supporting arm 102.

[0030] The first supporting arm 101 proposed in the present embodiment is provided with a positioning groove 112, in which an elastic positioning block 113 is slidably provided, and the elastic positioning block 113 is elastically connected to the first supporting arm 101, and the elastic positioning block 113 is configured to retract into the interior of the positioning groove 112 when under pressure. When the plate conveying assembly 300 conveys the plate to the first supporting arm 101, the plate contacts the elastic positioning block 113 and applies pressure to the elastic positioning block 113, so that the elastic positioning block 113 retracts into the interior of the positioning groove 112, and the elastic positioning block 113 no longer blocks the passage of the plate, and the plate can be smoothly moved to the first supporting arm 101.

[0031] When the plate has completely passed through the elastic positioning block 113, the elastic positioning block 113 is no longer under pressure and rebounds to its original position from the positioning groove 112, thereby blocking the plate and preventing the plate from sliding back onto the plate conveying assembly 300. The position of the elastic positioning block 113 in the positioning groove 112 can be adjusted according to the width of the plate to ensure that the elastic positioning block 113 can block the sliding of the plate after the plate has completely passed through the elastic positioning block 113, which is suitable for plates of different sizes and widths.

[0032] The second bearing arm 102 proposed in this embodiment is provided with a limit plate 114, and the limit plate 114 is movably arranged on one end of the second bearing arm 102 away from the central rotating shaft 103. The limit plate 114 is provided with a distance adjusting nut 115, and the distance adjusting nut 115 is configured to adjust the position of the limit plate 114 on the second bearing arm 102. When the plate slides from the first bearing arm 101 to the second bearing arm 102, the limit plate 114 blocks the further sliding of the plate and limits the position of the plate between the limit plate 114 and the central rotating shaft 103, which has the same function as the elastic positioning block 113 to prevent the plate from sliding on the second bearing arm 102.

[0033] The distance adjusting nut 115 proposed in this embodiment is configured to adjust the position of the limit plate 114 on the second supporting arm 102. The distance between the limit plate 114 and the central rotating shaft 103 is adjusted by the distance adjusting nut 115, which is suitable for plates of different sizes and widths.

[0034] The present embodiment proposes that a feed ramp 110 is provided at the head position of one end of the first bearing arm 101 away from the central rotating shaft 103, and a roller 111 is provided on the feed ramp 110, and the roller 111 is rollingly connected to the feed ramp 110. When the plate conveying assembly 300 conveys the plate to the first bearing arm 101, the plate first contacts the end of the first bearing arm 101 away from the central rotating shaft 103. At this time, the feed ramp 110 at this position facilitates the smooth conveyance of the plate to the first bearing arm 101. At the same time, the roller 111 on the feed ramp 110 can reduce the friction between the feed ramp 110 and the plate, thereby facilitating the conveyance of the plate from the plate conveying assembly 300 to the first bearing arm 101.

[0035] The second carrying arm 102 proposed in this embodiment is provided with an adsorption plate 116, and a plurality of electromagnet coils 117 are provided on the adsorption plate 116. The electromagnet coils 117 are configured to magnetically adsorb the plate when alternating current is applied. When this embodiment is in use, the servo motor 104 is rotated to drive the central shaft 103 to rotate, so that the plate slides from the first carrying arm 101 to the second carrying arm 102, and then the electromagnet coil 117 is energized to generate magnetic force. The magnetic force generated by the electromagnet coil 117 adsorbs the plate on the adsorption plate 116. When the second carrying arm 102 is in an inclined state relative to the horizontal plane, the adsorption plate 116 generates an adsorption force on the plate to prevent the plate from sliding off the second carrying arm 102.

[0036] The welding mobile kit 200 proposed in this embodiment includes a fixed hanging rail 201 and an electric overhead crane 203, the electric overhead crane 203 is slidably arranged on the fixed hanging rail 201, the fixed hanging rail 201 is arranged directly above the central rotating shaft 103, and the electric overhead crane 203 is provided with a hoisting rope 205 and a welding gun cover 204, the welding gun cover 204 is connected to the electric overhead crane 203 through the hoisting rope 205, the electric overhead crane 203 controls the lifting and lowering of the welding gun cover 204 through the hoisting rope 205, and the welding gun cover 204 is configured to install a welding gun.

[0037] When in use, the present embodiment uses the plate positioning and splicing assembly 100 to splice two plates together, and makes the edge positions of the two plates fit together, and the fitting position is located above the central rotating shaft 103. At this time, the welding gun is fixed in the welding gun sleeve 204, and the electric overhead crane 203 lowers the welding gun sleeve 204 to the vicinity of the central rotating shaft 103 through the hoisting rope 205, so that the welding gun is aligned with the fitting position of the plates. Then the electric overhead crane 203 drives the welding gun sleeve 204 to move on the fixed hanging rail 201, and the welding gun on the welding gun sleeve 204 moves synchronously along the fitting position of the plates. During the movement, the welding gun welds the plates, thereby ensuring the straightness of the weld.

[0038] The welding mobile kit 200 proposed in this embodiment also includes a welding track 202, which is arranged directly below the fixed hanging rail 201, and the welding gun cover 204 is slidably arranged on the welding track 202. When this embodiment is in use, when the electric overhead crane 203 moves on the fixed hanging rail 201, the welding gun cover 204 is pulled to move on the welding track 202 by the hoisting rope 205. By setting the welding track 202, the moving path of the welding gun cover 204 is limited to the welding track 202, which prevents the suspended welding gun cover 204 from swinging, and further ensures the quality of welding.

[0039] The plate conveying assembly 300 proposed in this embodiment includes a conveying bracket 301, a conveyor belt 302 and a conveying motor 303. The conveying bracket 301 is rotatably provided with a conveying roller 304, the conveyor belt 302 is arranged on the conveying roller 304, the output end of the conveying motor 303 is connected to the conveying roller 304, and the conveying motor 303 is configured to drive the conveyor belt 302 to move through the conveying roller 304. When in use, this embodiment places the plate on the conveyor belt 302, and then starts the conveying motor 303 to work. The conveying motor 303 drives the conveying roller 304 to rotate, and the conveying roller 304 further drives the conveyor belt 302 to convey the plate to the first carrying arm 101.

[0040] In this embodiment, a plurality of anti-skid belts 305 are arranged in an array on the outer surface of the conveyor belt 302. The anti-skid belts 305 are protrusions higher than the surface of the conveyor belt 302. The anti-skid belts 305 are used to increase the friction between the conveyor belt 302 and the plate to prevent the conveyor belt 302 from slipping when conveying the plate.
