Description

Technical Field

[0001] This invention relates to the field of angle steel processing technology, and in particular to a welding auxiliary device for processing angle steel towers. Background Technology

[0002] Angle steel is widely used as the main structural material of angle steel towers because it can withstand pressure, bending and shear forces, making it suitable for the lateral structure of the legs and diagonal braces of angle steel towers. Since angle steel is used in different locations of angle steel towers and needs to have different functions, it is often necessary to add additional components to the angle steel, such as reinforcing plates, node plates, base plates, flange structures, etc. Therefore, welding equipment is needed to weld these additional components to the angle steel.

[0003] Chinese patent document CN117266655A discloses a root support structure for the main material of a transmission tower, belonging to the field of transmission tower main material reinforcement technology. This invention addresses the problem of poor deformation resistance of angle steel structures used as the main material of transmission towers. It includes: an inner auxiliary support unit fixed to the inner wall of the root section of the angle steel support leg; the inner auxiliary support unit comprises an inner auxiliary angle steel section, multiple reinforcing ribs, and multiple horizontal support plates; the inner auxiliary angle steel section is fixed to the inner wall of the angle steel support leg; multiple horizontal support plates are evenly arranged from top to bottom on the inner auxiliary angle steel section; the horizontal support plates are triangular, with two sides of the horizontal support plates fitting against the inner wall of the inner auxiliary angle steel section; a reinforcing rib is arranged between every two horizontal support plates; the outer surface of the reinforcing rib is parallel to the third side of the horizontal support plate; the reinforcing rib is positioned near the angle of the inner auxiliary angle steel section; the reinforcing rib is plate-shaped or block-shaped with a triangular cross-section; two surfaces of the block-shaped reinforcing rib fit against the inner wall of the inner auxiliary angle steel section. This invention is used for auxiliary support at the root of the main material.

[0004] The existing technology has the following problems:

[0005] In order to enhance the supporting capacity of the angle steel, multiple evenly arranged reinforcing plates are often welded inside the angle steel at the support legs of existing angle steel towers. Since multiple reinforcing plates are required and they need to be evenly arranged, existing welding equipment is difficult to weld in large quantities stably and effectively due to the problem of feeding the reinforcing plates. If a robotic arm is used for feeding, the cost will increase in terms of debugging and maintenance of the robotic arm during the production process. Summary of the Invention

[0006] The main objective of this invention is to provide a welding auxiliary device for processing angle steel towers, which can effectively solve the problems of difficulty in feeding reinforcing plates and difficulty in feeding them quickly, cost-effectively, and stably.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0008] A welding auxiliary device for processing angle steel towers includes a housing. A V-shaped conveyor is fixedly connected to the bottom inner side of the housing. A V-shaped storage platform is fixedly connected to the top inner side of the housing near the right side. The upper inner side of the housing has two processing mechanisms (front and rear) and a feeding mechanism located between the two processing mechanisms. The feeding mechanism is located directly above the V-shaped conveyor. The upper side of the housing has a lifting mechanism. The feeding mechanism includes two welding components (left and right), two suction plates (front and rear), and two pusher frames. The bottom of the V-shaped storage platform has a pushing mechanism for pushing reinforcing plates.

[0009] The lifting mechanism drives the pusher to move up and down, and the pusher converts the up and down movement into left and right movement, so that the suction plate moves left and right. The suction plate picks up the leftmost reinforcing plate and moves it between the two welding components. Then the reinforcing plate moves down with the welding components.

[0010] Preferably, the feeding mechanism further includes an L-shaped lifting frame driven by the lifting mechanism and two front and rear sliding tubes. The welding assembly is located on the left and right sides of the vertical wall of the L-shaped lifting frame. The lower side of the sliding tube is fixedly connected to the upper side of the V-shaped storage platform near the left side. The right side of the suction plate is slidably connected to the inner side of the sliding tube through a moving column. The upper side of the pusher is fixedly connected to the lower side of the L-shaped lifting frame near the front and rear sides. Pushing shafts are slidably connected to the inner sides of the two pushers. The ends of the two pushers that are close to each other pass through the side wall of the sliding tube and are fixedly connected to the moving column.

[0011] Preferably, each of the two suction plates has a push plate fixedly connected to the right side of the slide tube via a long rod. Each of the two slide tubes has a limit ring fixedly connected to the middle of its inner side, with the push plate located to the right of the limit ring. Each of the two slide tubes has a spring sleeved on its inner side, with the spring located between the push plate and the limit ring.

[0012] Preferably, the left side of the vertical wall of the L-shaped lifting frame is rotatably connected to an L-shaped rotating frame driven by a torsion spring, and the right side of the L-shaped rotating frame is provided with a clamping plate. The distance between the clamping plate and the right side of the vertical wall of the L-shaped lifting frame is adjusted by setting a screw on the L-shaped rotating frame. The left and right sides of the vertical wall of the L-shaped lifting frame are provided with slots for the clamping plate to pass through, and the sides of the vertical wall of the L-shaped lifting frame that are close to each other and the clamping plate are provided with vibration damping pads.

[0013] Preferably, the feeding mechanism further includes a lifting plate driven by the lifting mechanism, and the lifting plate is located on the left side of the L-shaped lifting frame. The L-shaped lifting frame and the lifting plate are independently driven to lift by the lifting mechanism. The left side of the lifting plate is fixedly connected to two push blocks in the front and rear through a vertical plate. The front and rear rotating positions of the L-shaped frame are fixedly connected to two torsion plates in the front and rear. When the torsion plate approaches the push block, the push block pushes down the torsion plate, causing the L-shaped frame to rotate counterclockwise.

[0014] Preferably, the processing mechanism includes a sliding sleeve and a sliding table slidably connected to its inner side. A rotating frame is fixedly connected to the upper side of the sliding sleeve, and a grinding assembly is provided on the lower side of the sliding table. The front and rear grinding assemblies are arranged in a V-shape, and the lower side of the leftmost reinforcing plate overlaps the upper side of the grinding disc in the grinding assembly. The upper side of the rotating frame is rotatably connected to the lower side of the lifting plate.

[0015] Preferably, the inner upper and lower sides of the outer shell of the mechanism are fixedly connected with round rods, and the outer side of the round rods passes through the rotating connection between the rotating frame and the lifting plate. The outer side of the round rods is rotatably connected to a rotating plate. The left side of the slide is rotatably connected with two first eccentric gears. The left side of the slide sleeve is rotatably connected with a second eccentric gear that meshes with the first eccentric gears, and the second eccentric gear is located between the two first eccentric gears. A spur gear is fixedly connected to the left rotation center of the second eccentric gear. A rack that meshes with the spur gear is fixedly connected to the left side of the rotating plate. The left and right sides of the rotating plate are provided with slots so that the spur gear and the second eccentric gear are located on both sides of the rotating plate.

[0016] Preferably, the outer side of the round rod is provided with several annularly distributed guide grooves. The rotating frame is slidably connected to the inner side of the guide grooves via a round shaft at its rotation position. When the rotating frame approaches the lowest side, as the rotating frame moves down, it is guided by the guide grooves, causing the rotating plate and the round rod to rotate, and the two grinding components on the front and rear sides move away from each other and disengage from the upper part of the V-shaped conveyor table.

[0017] Preferably, a mounting bracket is fixedly connected to the left side of the rotating plate near the bottom, and a slide block is adjustablely fixedly connected to the upper side of the mounting bracket. The distance between the slide block and the rotating plate can be adjusted by adjusting the fixing measures. The annular sleeves of the slide blocks on the front and rear sides are movably connected to a limit rod at one end, and the limit rod is placed inside the V-shaped conveyor table. The bottom of the limit rod is hemispherical.

At the same time, the two operations are linked to each other, making the whole device more compact.

[0020] 2. This invention provides a welding auxiliary device for processing angle steel towers. Based on the cooperation of a lifting mechanism, a processing mechanism, a sliding sleeve, a sliding table, a grinding component, a first eccentric gear, a second eccentric gear, a spur gear, a rack, a round rod, a rotating frame, a guide groove, a rotating plate, a mounting frame, a sliding seat, a limiting rod, and a limiting plate, the grinding component is driven to move up and down by the lifting mechanism to achieve grinding of the bottom of the reinforcing plate, thereby improving the welding yield. The movement of the angle steel is limited by the limiting rod, so that the spacing of the reinforcing plates remains constant. Attached Figure Description

[0033] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0034] Example 1, as Figures 1-3 As shown, a welding auxiliary device for processing angle steel towers includes a housing 1. A V-shaped conveyor table 3 is fixedly connected to the bottom inner side of the housing 1. Material inlets 2 are provided on the left and right sides of the housing 1, directly opposite the left and right sides of the V-shaped conveyor table 3, to facilitate the entry and exit of angle steel. The V-shaped conveyor table 3 is equipped with needle rollers inside to reduce the friction between the V-shaped conveyor table 3 and the angle steel. A blower-type heat dissipation structure is provided on the side wall of the housing 1 to prevent the temperature generated during welding from accumulating inside the housing 1.

[0035] A V-shaped storage platform 4 is fixedly connected to the top inner side of the outer casing 1 near the right side. The V-shaped storage platform 4 is used to store reinforcing plates. The upper inner side of the outer casing 1 is provided with two processing mechanisms 6 and a feeding mechanism 5 located between the two processing mechanisms 6. The feeding mechanism 5 is located directly above the V-shaped conveyor platform 3. The upper side of the outer casing 1 is provided with a lifting mechanism 7. The feeding mechanism 5 includes two welding components 52 on the left and right, two suction plates 53 on the front and back, and two pusher frames 54. The bottom of the V-shaped storage platform 4 is provided with a pushing mechanism for pushing the reinforcing plates. The pushing mechanism can be driven by a hydraulic rod or a screw to push the stack of reinforcing plates to the left.

[0036] The lifting mechanism 7 drives the pusher frame 54 to move up and down. The lifting mechanism 7 can be in the form of an electric cylinder. The pusher frame 54 converts the up and down movement into left and right movement, so that the suction plate 53 moves left and right. The suction plate 53 can be used for electromagnetic adsorption or negative pressure adsorption to adsorb the reinforcing plate. The movement of the suction plate 53 can drive the reinforcing plate to move to the left. The suction plate 53 adsorbs the leftmost reinforcing plate and moves it between the two welding components 52. Then the reinforcing plate moves down with the welding components 52.

[0037] It should be noted that the front of the housing 1 is equipped with a control panel, and the upper right side of the housing 1 is equipped with an opening for convenient placement of reinforcing plates, and a flip-up door is provided to close this opening.

[0038] Example 2, as Figures 4-8 As shown, the feeding mechanism 5 also includes an L-shaped lifting frame 51 driven by the lifting mechanism 7 and two front and rear sliding tubes 55. The upper wall of the L-shaped lifting frame 51 has a long front and rear side spacing, so that the two push frames 54 can be as far apart as possible. The welding assembly 52 is located on the left and right sides of the vertical wall of the L-shaped lifting frame 51. The welding assembly 52 is used to weld the reinforcing plate and the angle steel.

[0039] The lower side of the slide tube 55 is fixedly connected to the upper side of the V-shaped storage platform 4 near the left side. The right side of the suction plate 53 is slidably connected to the inner side of the slide tube 55 via a moving column. The upper side of the pusher frame 54 is fixedly connected to the lower side of the L-shaped lifting frame 51 near the front and rear sides. The pusher frame 54 is in the shape of an inclined rail with open upper and lower ends. The inner sides of both pusher frames 54 are slidably connected to pusher shafts 514. When the pusher frame 54 moves down from the uppermost side, the pusher shaft 514 slides into the pusher frame 54 from the lower end of the pusher frame 54. As the pusher frame 54 moves down, it continuously pushes the pusher shaft 514 to move to the left. The ends of the two pusher shafts 514 that are close to each other pass through the side wall of the slide tube 55 and are fixedly connected to the moving column.

[0040] Preferably, each of the two suction plates 53 has a push plate 56 fixedly connected to the right side of the slide tube 55 via a long rod. Each of the two slide tubes 55 has a limit ring 57 fixedly connected to the middle of its inner side. The long rod passes through the inner side of the limit ring 57, and the push plate 56 is located to the right of the limit ring 57. Each of the two slide tubes 55 has a spring 58 sleeved on its inner side. The spring 58 is used to push the push plate 56 to reset the suction plate 53, and the spring 58 is located between the push plate 56 and the limit ring 57.

[0041] When the suction plate 53 is fully reset, the spring 58 is in an uncompressed state. At the same time, the push plate 56 is fixedly connected to the end of the spring 58. When the push frame 54 moves up from the bottom to reset, due to the structure of the push frame 54, it will move to the right, and the spring 58 will be stretched. This does not affect the reset of the push frame 54. After the push frame 54 is reset, the suction plate 53 will return to its original state.

[0042] It should be noted that the lifting mechanism 7 drives the L-shaped lifting frame 51 to move downward, which in turn causes the welding assembly 52 and the pusher frame 54 to move downward. When the pusher shaft 514 slides into the pusher frame 54, the downward movement of the pusher frame 54 causes the suction plate 53 to move to the left. The suction plate 53 adsorbs a reinforcing plate. Due to the continuous downward movement of the pusher frame 54, it enters between the two welding assemblies 52. Finally, the pusher frame 54 continues to move downward, the pusher shaft 514 disengages from the suction plate 53, causing the suction plate 53 to reset. The L-shaped lifting frame 51 then drives the reinforcing plate and the welding assembly 52 to move downward, completing the loading and welding process.

[0043] Preferably, an L-shaped rotating frame 59 driven by a torsion spring is rotatably connected to the left side of the vertical wall of the L-shaped lifting frame 51. A clamping plate 510 is provided on the right side of the L-shaped rotating frame 59. The distance between the clamping plate 510 and the right side of the vertical wall of the L-shaped lifting frame 51 is adjusted by setting a screw on the L-shaped rotating frame 59. A threaded tube is provided on the clamping plate 510. The threaded tube is inserted into the cavity on the L-shaped rotating frame 59 where the screw is installed. The screw is threadedly connected to the threaded tube. Rotating the screw can drive the clamping plate 510 to move. The left and right sides of the vertical wall of the L-shaped lifting frame 51 have slots for the clamping plate 510 to pass through. The L-shaped lifting frame 51 has a structure to stabilize the L-shaped rotating frame 59. This can be in the form of electromagnetic adsorption, clamping block clamping, or adding a damping structure to the torsion spring to prevent the L-shaped rotating frame 59 from being driven to rotate during subsequent grinding.

[0044] The vertical wall of the L-shaped lifting frame 51 and the side of the clamping plate 510 that are close to each other are provided with vibration damping pads. The vibration damping pads can effectively reduce the vibration of the reinforcing plate during subsequent grinding of the reinforcing plate, and also enhance the friction between the L-shaped lifting frame 51, the clamping plate 510 and the reinforcing plate.

[0045] Preferably, the feeding mechanism 5 also includes a lifting plate 512 driven by the lifting mechanism 7, and the lifting plate 512 is located on the left side of the L-shaped lifting frame 51. The L-shaped lifting frame 51 and the lifting plate 512 are driven to lift independently by the lifting mechanism 7. The L-shaped lifting frame 51 and the lifting plate 512 can move up and down at the same time or move separately. The left side of the lifting plate 512 is fixedly connected to two front and rear push blocks 513 by a vertical plate. The front and rear rotating positions of the L-shaped rotating frame 59 are fixedly connected to two front and rear torsion plates 511. When the torsion plate 511 approaches the push block 513, the push block 513 pushes down the torsion plate 511, causing the L-shaped rotating frame 59 to rotate counterclockwise.

[0046] It should be noted that when the L-shaped lifting frame 51 moves down from the top, the pushing frame 54 pushes the pushing shaft 514, causing the suction plate 53 to pull the reinforcing plate to the left. At the same time, the L-shaped rotating frame 59 rotates. After the reinforcing plate is loaded, the clamping plate 510 also completes the function of fixing the reinforcing plate.

[0047] Example 3, as Figures 8-11As shown, the processing mechanism 6 includes a sliding sleeve 61 and a sliding table 62 slidably connected to its inner side. A rotating frame 69 is fixedly connected to the upper side of the sliding sleeve 61. A grinding assembly 63 is provided on the lower side of the sliding table 62. The grinding assembly 63 adopts the form of a motor-driven grinding disc. The motor is installed at the lower end of the sliding table 62. The grinding disc acts as a support for the reinforcing plate. The motor drives the grinding disc to rotate and grind the bottom of the reinforcing plate. The two grinding assemblies 63 are arranged in a V-shape. The lower side of the leftmost reinforcing plate overlaps the upper side of the grinding disc in the grinding assembly 63. The upper side of the rotating frame 69 is rotatably connected to the lower side of the lifting plate 512.

[0048] Preferably, a round rod 68 is fixedly connected to the upper and lower sides of the inner side of the outer casing 1 of the mechanism, and the outer side of the round rod 68 passes through the rotating connection of the rotating frame 69 and the lifting plate 512. A rotating plate 611 is rotatably connected to the outer side of the round rod 68. The rotating position of the rotating plate 611 and the round rod 68 is located on the side where the rotating frame 69 and the lifting plate 512 are far away from each other, so as not to affect the movement of the rotating frame 69.

[0049] The left side of the slide table 62 is rotatably connected to two first eccentric gears 64, and the left side of the sliding sleeve 61 is rotatably connected to a second eccentric gear 65 that meshes with the first eccentric gears 64. The second eccentric gear 65 is located between the two first eccentric gears 64. When the second eccentric gear 65 rotates, it drives the two first eccentric gears 64 to rotate. Due to the structure of the second eccentric gear 65 and the first eccentric gear 64, the slide table 62 reciprocates within the sliding sleeve 61 when the first eccentric gear 64 rotates. A spur gear 66 is fixedly connected to the left rotation center of the second eccentric gear 65. A rack 67 that meshes with the spur gear 66 is fixedly connected to the left side of the rotating plate 611. The left and right sides of the rotating plate 611 are provided with slots so that the spur gear 66 and the second eccentric gear 65 are located on both sides of the rotating plate 611.

[0050] It should be noted that the lifting mechanism 7 drives the lifting plate 512 to move down, which in turn causes the rotating frame 69 to move down. During the downward movement of the rotating frame 69, the sliding sleeve 61 moves down, which causes the rack 67 to drive the spur gear 66 to rotate, which in turn drives the second eccentric gear 65 to rotate. This causes the slide table 62 to move up and down reciprocally within the sliding sleeve 61, which causes the grinding disc on the grinding assembly 63 to move obliquely back and forth, thus improving the grinding effect.

[0051] Preferably, the outer side of the round rod 68 is provided with several annularly distributed guide grooves 610. The rotating frame 69 is slidably connected to the inner side of the guide grooves 610 via a round shaft at its rotation position. When the rotating frame 69 is close to the lowermost side, an electromagnetic adsorption structure can be provided between the lifting plate 512 and the rotating frame 69 to stabilize the rotating frame 69 during its up-and-down movement before it needs to rotate. As the rotating frame 69 moves down, it is guided by the guide grooves 610 to make the rotating plate 611 and the round rod 68 rotate, and the two grinding components 63 on the front and rear sides move away from each other and disengage from the upper part of the V-shaped conveyor table 3.

[0052] Preferably, a mounting bracket 612 is fixedly connected to the left side of the rotating plate 611 near the bottom. A slide block 613 is adjustablely fixedly connected to the upper side of the mounting bracket 612. The adjustment method can be fixed with screws and nuts. The distance between the slide block 613 and the rotating plate 611 can be adjusted by adjusting the fixing measures. This distance is adjusted by the spacing of the reinforcing plates on the angle steel.

[0053] The annular sleeves of the front and rear slides 613 are movably connected to the limit rods 614 at one end, and the limit rods 614 are placed inside the V-shaped conveyor table 3. The bottom of the limit rods 614 is hemispherical. The front and rear sides of the V-shaped conveyor table 3 are fixedly connected to the limit plates 615, which can effectively prevent the limit rods 614 from falling down after they are removed from the upper side of the V-shaped conveyor table 3, which would make it difficult to reset.

[0054] The working principle of this invention is as follows: First, the lifting mechanism 7 drives the L-shaped lifting frame 51 to move downwards, causing the L-shaped lifting frame 51 to move the welding assembly 52 and the pushing frame 54 downwards. When the pushing shaft 514 slides into the pushing frame 54, the downward movement of the pushing frame 54 causes the suction plate 53 to move to the left, and the suction plate 53 adsorbs a reinforcing plate. Due to the continuous downward movement of the pushing frame 54, it enters between the two welding assemblies 52. Finally, the pushing frame 54 continues to move downwards, the pushing shaft 514 disengages from the suction plate 53, causing the suction plate 53 to reset. The L-shaped lifting frame 51 then drives the reinforcing plate and the welding assembly 52 downwards, completing the loading and welding. Through the process of the lifting mechanism 7 driving the welding assembly 52 to move up and down, the automatic loading of the reinforcing plate is achieved, improving the angle steel. The welding efficiency of the reinforcing plate is improved, and the two operations are linked to each other, making the whole more compact. Finally, the lifting mechanism 7 drives the lifting plate 512 to move down, which causes the rotating frame 69 to move down. During the downward movement of the rotating frame 69, the sliding sleeve 61 moves down, which causes the rack 67 to drive the spur gear 66 to rotate, which in turn drives the second eccentric gear 65 to rotate. This causes the slide table 62 to move up and down in the sliding sleeve 61, which causes the grinding disc on the grinding assembly 63 to move obliquely back and forth, improving the grinding effect. During the up and down movement of the grinding assembly 63 driven by the lifting mechanism 7, the bottom of the reinforcing plate is ground, improving the welding yield. The movement of the angle steel is limited by the limit rod 614, so that the spacing of the reinforcing plates is constant.

[0055] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
