Description

Technical Field

[0001] This invention relates to the field of welding of iron tower components, specifically to a rapid welding device for iron tower components and its usage method. Background Technology

[0002] In the construction of power transmission towers, the cross-shaped component is the core load-bearing and connecting part. Its manufacturing quality is directly related to the overall structural safety of the tower. In order to improve the connection strength and bending resistance of the cross-shaped component, it is usually necessary to weld multiple reinforcing ribs at its right-angle connection. At present, this welding process is generally carried out manually or semi-automatically.

[0003] The following problems exist in the existing technology that have not been well resolved: Although some existing welding equipment can complete the welding action, auxiliary processes such as material picking, feeding, and pre-positioning of reinforcing ribs still rely on manual intervention. This makes the continuity of the entire welding process poor, and the accuracy of manual pre-positioning is inconsistent, which can easily cause large welding thermal deformation of the workpiece during welding, affecting the consistency of the welded joint and the final product quality.

The reset spring is disposed between the limiting block and the limiting ring, and the elastic force of the reset spring is 3 times that of the return spring. One end of the push rod is fixedly connected to a hinge pin, and the lower part of the connecting plate is provided with a hinge groove, and the hinge pin is slidably disposed inside the hinge groove.

[0008] Preferably, the top of the pad is chamfered, and both sides of the inner wall of the through groove are provided with movable grooves that cooperate with the pin. The two pads are slidably disposed inside the two movable grooves respectively. The two pins are symmetrically arranged at the bottom of the picking plate, and the distance between the two pins is 0.6 times the width of the picking plate.

[0009] Preferably, the unloading mechanism includes: a movable plate that is horizontally slidably disposed at one end of the picking plate, a magnetic block that is vertically slidably disposed in the middle of the movable plate, a sinking groove being provided at the bottom of the magnetic block, and an L-shaped guide groove being provided between the two sides of the inner wall of the sinking groove. A T-shaped guide rod is slidably disposed between two L-shaped guide grooves, with one end of the T-shaped guide rod passing through the movable plate and fixedly connected to the side wall of the picking plate.

At the same time, the reinforcing ribs are elastically supported and pressed by the pad and the L-shaped pressure plate. Combined with the adaptive positioning function of the unloading mechanism, the reinforcing ribs and the right angle reference of the cross component are quickly and automatically aligned and fitted without manual intervention, which greatly shortens the auxiliary process time and improves the continuity and efficiency of the welding operation.

[0013] In this invention, the reinforcing ribs are stably pre-tightened and positioned by the pad and L-shaped pressure plate, ensuring that the reinforcing ribs at the diagonal positions of the cross-shaped component can maintain precise relative positions during the welding process.

Combined with the component fixture indexing and rotation function driven by the servo motor, the reinforcing ribs can be automatically replenished and supplemented during the return process of the storage rack when switching to the next station after welding a set of diagonal reinforcing ribs. This enables continuous automatic welding of multiple stations and multiple welds, significantly improving the overall processing efficiency and finished product consistency of the tower components.

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Please see Figures 1 to 8 This invention provides a technical solution: a rapid welding device for iron tower components, including a welding support 1, a component clamp 2 rotatably mounted on the axial position of the welding support 1, storage racks 3 slidably mounted on both sides of the welding support 1, and a welding robot 4 slidably mounted on the side wall of the welding support 1. It should be noted that: the component clamp 2 clamps and positions the cross-shaped component, then the storage racks 3 move the reinforcing ribs to the side wall position of the cross-shaped component, and the welding robot 4 welds the reinforcing ribs to the surface of the cross-shaped component.

[0018] It also includes: a clamping mechanism 5 movably mounted on the surface of the storage rack 3 for automatically clamping the welded parts; and an arc-shaped protrusion 6 fixedly connected to the top of the welding support 1 for driving the clamping mechanism 5. It should be noted that: the two arc-shaped protrusions 6 are respectively located on both sides of the welding support 1. When the storage rack 3 moves away from the center of the welding support 1, the clamping mechanism 5 on the storage rack 3 contacts the arc-shaped protrusions 6.

[0019] The unloading mechanism 7, which is installed at the part-taking end of the clamping mechanism 5, is used to automatically position and remove the welded parts.

[0020] In this embodiment, as Figures 1 to 8As shown, the clamping mechanism 5 includes a V-shaped groove 501 formed on the upper part of the storage rack 3, and an electric feeding rod 502 for driving the movement of the welded parts is movably installed inside the V-shaped groove 501. It should be noted that a round bar is fixedly connected to the inner wall of the V-shaped groove 501. The round bar reduces the frictional resistance of the reinforcing ribs moving inside the V-shaped groove 501. The electric feeding rod 502 pushes the reinforcing ribs stored inside the storage rack 3 to the port position of the V-shaped groove 501, facilitating automatic removal by the clamping mechanism 5.

[0021] An L-shaped bracket 503 is fixedly installed on the top of the storage rack 3. A pick-up plate 504 is rotatably connected to the middle of the L-shaped bracket 503. A magnetic block 505 for picking up the welded parts at the port position of the V-groove 501 is movably installed at one end of the pick-up plate 504.

[0022] A connecting plate 506 is fixedly installed at the other end of the picking plate 504, and a push rod 507 is hinged to the lower part of the connecting plate 506. The right end of the push rod 507 overlaps with the surface of the adjacent arc-shaped convex plate 6, and a return spring 508 is movably connected between the surface of the push rod 507 and the top of the L-shaped bracket 503. It should be noted that: when the storage rack 3, carrying the L-shaped bracket 503, leaves the side wall of the cross-shaped component, and the push rod 507 does not contact the arc-shaped protrusion 6, under the action of the return spring 508, the push rod 507 flips the connecting plate 506 and the picking plate 504, causing the picking plate 504 to flip downwards to a vertical state, and the magnetic block 505 picks up the reinforcing rib at the port of the V-groove 501; while the storage rack 3 continues to move with the L-shaped bracket 503, after the push rod 507 contacts the arc-shaped protrusion 6, the push rod 507 is restricted by the arc-shaped protrusion 6 and under the reaction force, the push rod 507 drives the connecting plate 506 and the picking plate 504 to flip upwards to a horizontal state, so as to facilitate the delivery of the picked-up reinforcing rib to the welding position of the cross-shaped component.

[0023] A pad 509 is slidably mounted on the side wall of the L-shaped bracket 503 to support the welded parts. One end of the pad 509 is movably connected to the inner wall of the L-shaped bracket 503 by a return spring 510. A pin 511 that cooperates with the part-retrieving plate 504 is fixedly connected to the side wall of the pad 509. It should be noted that when the part-retrieving plate 504 flips downward, it contacts the pin 504, thereby driving the pin 511 to slide the pad 509 into the L-shaped bracket 503, avoiding interference with the flipping of the reinforcing rib after it has been picked up. When the part-retrieving plate 504 flips to a horizontal state, it gradually releases the pressure on the pin 511. At this time, the return spring 510 gradually extends the pad 509 from inside the L-shaped bracket 503 and supports the bottom of the reinforcing rib in the horizontal state.

[0024] In this embodiment, as Figures 1 to 8As shown, the top of the L-shaped bracket 503 has a groove, and an L-shaped pressure plate 512 is rotatably connected inside the groove. A torsion spring is fixedly connected between the surface of the L-shaped pressure plate 512 and the inner wall of the groove. It should be noted that: through the cooperation of the torsion spring and the L-shaped pressure plate 512, and under the action of the unloading mechanism 7, when the magnetic block 505 on the picking plate 504 releases its adsorption on the reinforcing rib, the torsion spring drives the L-shaped pressure plate 512 to press against the top of the reinforcing rib on the surface of the pad 509, improving the stability of the reinforcing rib during the welding process; and the bottom of the L-shaped pressure plate 512 is provided with steel balls to reduce the resistance of the reinforcing rib in the process of self-adjustment of position during the engagement of the right angle surface of the cross-shaped component, so that the reinforcing rib can stably adhere to the pad 509 and automatically align under the driving constraint of the L-shaped bracket 503.

[0025] The L-shaped bracket 503 has a through groove in the middle, and the picking plate 504 is movably installed in the through groove. The L-shaped bracket 503 has symmetrical pads installed on its surface, and a shaft is rotatably connected between the two pads. The picking plate 504 is fixedly installed in the middle position of the shaft.

[0026] In this embodiment, as Figures 1 to 8 As shown, a limiting ring 513 is fixedly sleeved in the middle of the push rod 507, and a limiting block 514 that cooperates with the limiting ring 513 is fixedly connected to the top of the storage rack 3. The push rod 507 is movably inserted in the middle of the limiting block 514. The reset spring 508 is disposed between the limiting block 514 and the limiting ring 513. The elastic force of the reset spring 508 is 3 times that of the return spring 510. It should be noted that when the return spring 508 moves downwards along with the connecting plate 506 and the picking plate 504 via the push rod 507, the driving force can overcome the elastic force of the return spring 510, allowing the picking plate 504 to stably engage with the pin 511 and carry the pad 509 into the L-shaped bracket 503. Here, a ball bearing can be installed between the pad 509 and the inner wall of the L-shaped bracket 503 to reduce frictional resistance during movement. At the same time, the setting of the limiting block 514 can effectively limit the position of the return spring 508 moving along with the connecting plate 506 via the push rod 507. After the connecting plate 506 moves to its limit position, the connecting plate 506 moves along with the picking plate 504 to a vertical position.

[0027] One end of the push rod 507 is fixedly connected to a hinge pin, and the lower part of the connecting plate 506 is provided with a hinge groove 515, and the hinge pin is slidably disposed inside the hinge groove 515.

[0028] In this embodiment, as Figures 1 to 8 As shown, the top of the pad 509 is chamfered, and both sides of the inner wall of the through groove are provided with movable grooves 516 that cooperate with the pin 511. The two pads 509 are respectively slidably disposed inside the two movable grooves 516.

[0029] Two pins 511 are symmetrically arranged at the bottom of the picking plate 504, and the distance between the two pins 511 is 0.6 times the width of the picking plate 504. It should be noted that the pins 511 are arranged on the flipping trajectory of the picking plate 504 and the movable plate 701. When the picking plate 504 flips downward, the bottom of the picking plate 504 can stably contact the two pins 511, ensuring that the two pads 509 move into the L-shaped bracket 503 at the same time.

[0030] In this embodiment, as Figures 1 to 8 As shown, the unloading mechanism 7 includes: a movable plate 701 that is horizontally slidably disposed at one end of the picking plate 504, a magnetic block 505 that is vertically slidably disposed in the middle of the movable plate 701, a sink trough 702 that is opened at the bottom of the magnetic block 505, and an L-shaped guide groove 703 that is opened between the two sides of the inner wall of the sink trough 702.

[0031] A T-shaped guide rod 704 is slidably disposed between two L-shaped guide grooves 703. One end of the T-shaped guide rod 704 passes through the movable plate 701 and is fixedly connected to the side wall of the picking plate 504. It should be noted that a circular hole is vertically opened in the middle of the movable plate 701, and the magnetic block 505 is vertically slidably disposed inside the circular hole. When the picking plate 504, with its suction reinforcing rib, flips to a horizontal position, due to the safety distance between the reinforcing rib and the side wall of the L-shaped bracket 503, when the storage rack 3, with its horizontal reinforcing rib, is attached to the side wall of the cross-shaped component, the restricted reinforcing rib moves the movable plate 701 towards the end of the picking plate 504. At this time, the T-shaped guide rod 704 on the picking plate 504... The magnetic block 505 slides in conjunction with the L-shaped guide groove 703 inside the magnetic block 505, causing the magnetic block 505 to move upward inside the circular hole. Then, the magnetic block 505 releases its adsorption on the reinforcing rib, allowing the L-shaped pressure plate 512 to press the reinforcing rib, which has been released from its adsorption state, against the top of the two pads 509, achieving automatic unloading. As the storage rack 3 continues to move, the flat side end of the reinforcing rib is fitted and positioned against the side wall of the L-shaped bracket 503, while the right-angle end of the reinforcing rib is stably fitted against the right-angle side wall of the cross-shaped component, achieving automatic positioning.

[0032] In this embodiment, as Figures 1 to 8 As shown, a spring telescopic rod 705 is fixedly connected between the side wall of the movable plate 701 and the side wall of the picking plate 504. A guide plate 706 is fixedly connected to the bottom of the movable plate 701, and a guide groove 707 is provided at the bottom of the picking plate 504. The guide plate 706 is slidably disposed inside the guide groove 707. It should be noted that: through the cooperation of the guide plate 706 and the guide groove 707, the picking plate 504 can stably drive the pin 511 and the pad 509 to slide along the trajectory of the moving groove 516 during the flipping process.

[0033] In this embodiment, as Figures 1 to 8As shown, a servo motor 8 is fixedly connected to the middle of the welding support 1, and the movable end of the servo motor 8 is fixedly connected to the bottom of the component clamp 2. It should be noted that the component clamp 2 consists of a turntable, four electric telescopic rods distributed along the circumference, and four right-angle clamping blocks. The movable end of the servo motor 8 is fixedly connected to the bottom of the turntable, and the electric telescopic rods and right-angle clamping blocks are distributed on the top of the turntable. The four electric telescopic rods move synchronously towards the center position of the turntable to clamp and position the cross-shaped component on the top of the turntable.

[0034] The welding support 1 has sliding grooves on both sides. The lower parts of the two storage racks 3 are slidably set inside the two sliding grooves, and the inner wall of the sliding groove is equipped with an electric telescopic top rod 9 that drives the storage racks 3 to move.

[0035] In this embodiment, as Figures 1 to 8 As shown, a method for using a rapid welding device for iron tower components includes the following steps: S1. In the initial stage of operation, the component clamp 2 is used to clamp and limit the cross component. Then, the electric telescopic top rod 9 drives the storage rack 3 to move towards the center of the welding support 1. The part-retrieving plate 504 and the pad 509 on the storage rack 3, along with the reinforcing ribs, are simultaneously conveyed to the right angle of the cross component. The reinforcing ribs are restricted by the side wall of the cross component, and the reaction force pushes the movable plate 701 to slide towards the end of the part-retrieving plate 504. The T-shaped guide rod 704 at the end of the part-retrieving plate 504 is guided along the L-shaped guide groove 703 built into the magnetic block 505. The drive magnetic block 505 rises along the inner wall of the movable plate 701 and releases the magnetic constraint on the reinforcing rib. The reinforcing rib falls between the two pads 509 and is firmly pressed against the upper surface of the pad 509 by the elastic pressing action of the L-shaped pressure plate 512 and the torsion spring. As the storage rack 3 continues to feed, the two right-angled sides of the reinforcing rib automatically align and fit with the right-angle reference of the cross component. Then, the welding robot 4 is controlled to perform synchronous welding on the two diagonally arranged reinforcing ribs. The precise pre-installation positioning suppresses welding deformation and ensures the quality of joint formation.

[0036] S2. After the welding process of the single diagonal reinforcing ribs is completed, the electric telescopic top rod 9 drives the storage rack 3 to retract in the reverse direction. The picking plate 504 on the L-shaped bracket 503 and the pad 509 separate from the position of the reinforcing ribs after welding. After the movable plate 701 loses the limiting load of the reinforcing ribs, the return spring 508 rebounds and drives the push rod 507 to move towards the corresponding arc-shaped convex plate 6. Before contacting the arc-shaped convex plate 6, the push rod 507 hinge pin and the hinge groove 515 of the connecting plate 506 slide hinge. With the cooperation of the connecting plate 506, the picking plate 504 is pulled downward and flipped. During the flipping process of the picking plate 504 and the movable plate 701, the pin 511 is moved along the length direction of the moving groove 516. The pad 509 retracts and is stored inside the moving groove 516 as the pin 511 moves, until the return spring 508 reaches the limit of its stroke. The picking plate 504 and the movable plate 701 flip downward by 90° and fit against the port of the V-shaped groove 501. The magnetic block 505 re-adsorbs the reinforcing rib to be welded in the groove.

[0037] S3, the storage rack 3 continues to move backward, so that the end face of the push rod 507 abuts against the outer wall of the adjacent arc-shaped convex plate 6 and is pressed. The push rod 507 is forced to move and is driven by the connecting plate 506 to flip the picking plate 504 upward. The reinforcing ribs adsorbed by the movable plate 701 are peeled out from the V-shaped groove 501 and lifted synchronously with the picking plate 504. During the upward flipping process of the picking plate 504, the pressure limit on the pin shaft 511 is gradually released. The return spring 510 in the moving groove 516 releases energy and pushes the pad plate 509, driving the pad plate 509 to gradually extend outward in the moving groove 516. When the picking plate 504 and the movable plate 701 with the reinforcing ribs rotate back to the horizontal state, the pad plate 509 is fully extended and completes the bottom support positioning of the new batch of reinforcing ribs.

[0038] S4. After the automatic feeding of the reinforcing ribs is completed, the servo motor 8 drives the component clamp 2 to rotate 90° along with the cross component to complete the welding station switch. The electric telescopic top rod 9 is started again to push the storage rack 3 to move towards the center of the welding support 1. The entire process of feeding, positioning and welding is repeated. During the interval between the return of the storage rack 3 and the indexing and repositioning of the cross component, the equipment realizes the automatic feeding of the reinforcing ribs through the linkage action of the picking plate 504 and the moving plate 701, thereby achieving continuous welding operation of nodes and effectively improving the overall processing efficiency of the components.
