Description

Technical Field

[0001] This invention relates to the field of welding technology, and in particular to a truss welding device for construction engineering. Background Technology

[0002] The field of welding technology encompasses the research, development, and application of processes and related equipment for forming permanent connections between metal workpieces using heat, pressure, or a combination of both. Its core content includes innovative welding methods, optimization of process parameters, and adaptation of welding equipment. It comprehensively covers various welding processes based on fundamental principles such as fusion welding, pressure welding, and brazing, as well as the application and equipment development of common welding methods such as arc welding, gas shielded welding, and resistance welding, widely serving the metal structure connection needs of industrial sectors such as construction machinery manufacturing.

[0003] One type of truss welding device for construction engineering refers to a specialized device applied in construction engineering scenarios to realize welding operations on truss components. The technical issues it addresses include the positioning, clamping, welding operation, welding position adjustment, and welding waste disposal of truss components. Positioning and clamping are achieved through a clamping baffle adjusting cylinder and adjusting block; the adjusting cylinder's drive component moves the clamping baffle to fit the truss component for fixation. Welding operations are performed by a robotic arm driving a welding torch; the robotic arm moves along a preset track to adjust the welding torch's position. Welding position adjustment is achieved by a hydraulic cylinder working in conjunction with an electromagnet plate to lift the truss component, changing its posture. Welding waste disposal is achieved by an air pump generating airflow to blow waste residue into a waste bin for collection.

[0004] Existing technologies rely solely on simple clamping structures to fix truss components, lacking a dual-fixation design. This results in insufficient adaptability to main beams of varying lengths, easily leading to welding misalignment. Simply moving the robotic arm to adjust the welding position results in poor precision. Furthermore, the lack of an effective feeding mechanism during the material feeding process leads to chaotic feeding, and the single-welding-gun operation mode is inefficient. These shortcomings are even more pronounced in batch welding of trusses or welding scenarios involving trusses of different specifications, reducing welding quality, increasing operation time, and impacting construction progress. Summary of the Invention

[0005] The main objective of this invention is to provide a truss welding device for construction engineering, which can effectively solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A truss welding device for construction engineering includes a machine base, an outer shell disposed at the upper end of the machine base, a storage box disposed at the upper end of the outer shell, and a controller disposed on one side of the machine base. A side beam welding structure for welding truss crossbeams is fixedly installed on the top wall of the inner cavity of the outer shell.

[0008] Preferably, the clamping drive includes a transmission disk rotatably mounted in the inner cavity of the base and connected to the chain belt drive. A toothed ring rotatably connected to the inner cavity of the base is fixedly mounted on the side of the transmission disk near the pipe fixing component. The toothed ring meshes with an adjacent pipe fixing component. A camshaft rotatably connected to the inner cavity of the base is fixedly connected to the middle of the side of the transmission disk near the pipe fixing component. The inner cavity of the base has an arc-shaped groove that matches the maximum outer diameter of the camshaft. The path of the arc-shaped groove is fan-shaped.

[0009] Preferably, the pipe fastener includes a chuck fixedly installed on one side of the base. On the side of the chuck away from the base, an outer wall clamping assembly for clamping the outer surface of the truss main beam is arranged in a ring.

A receiving groove is opened on the lower rear part of the storage bin's inner cavity. An L-shaped plate is slidably connected to the inner surface of the receiving groove by a spring. When the push plate is in the inner wall of the receiving groove, the front end of the push plate is flush with the rear side wall of the inner surface of the storage bin. When the push plate moves forward under the action of the electric screw, the L-shaped plate protrudes from the receiving groove under the action of the spring.

[0013] Preferably, the welding positioning assembly includes a crane, with a shielding cabinet fixedly connected to the upper end of the crane. The upper end of the crane is provided with a material unloading component for conveying the crossbeam and a welding component for welding the crossbeam.

Several guide plates are fixedly connected in an array on both the left and right sides of the lower end of the mounting plate. Each of the guide plates is rotatably connected to a support plate via a torsion spring on the side near the center of the mounting plate. The upper end of the trolley has an unloading port communicating with the lower end. The mounting plate is suspended above the unloading port. A stop block that restricts the position of the crossbeam is fixedly connected to the upper end of the trolley.

[0015] Preferably, the welding component includes a lifting platform, with cylinders mounted on the upper end of the crane on both the left and right sides of the lower end of the lifting platform. A spring limiting rod two, which is fixedly connected to the mounting plate, is slidably connected to the inner surface of the lifting platform. Mounting rods that fit against the two sides of the mounting plate are symmetrically fixedly connected to the lower end of the lifting platform. Plasma welding guns for welding the joint between the main beam and the crossbeam are symmetrically fixedly connected to the two mounting rods. A baffle higher than the plasma welding gun is fixedly connected to the side of the two mounting rods that are close to each other.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1.

[0021] 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.

[0022] Example 1: A truss welding device for construction engineering, see reference. Figure 1 and Figure 2The system includes a machine base 1, an outer shell 2 mounted on top of the machine base 1, a storage bin 4 mounted on top of the outer shell 2, and a controller 3 mounted on one side of the machine base 1. A side beam welding structure 6 for welding truss crossbeams is fixedly installed on the top wall of the inner cavity of the outer shell 2. A main beam positioning structure 5 for supporting and fixing the main truss crossbeams is symmetrically connected to the upper end of the machine base 1 via an electric telescopic rod. The storage bin 4 stores the crossbeam raw materials and is connected to the inner cavity of the outer shell 2. The controller 3 is the core control component of the entire device, coordinating the orderly operation of all components. The machine base 1 provides a stable installation foundation for all upper components, ensuring the overall stability of the device during operation. The design of the electric telescopic rod driving the main beam positioning structure 5 to slide allows for flexible adjustment of the distance between the two positioning structures, adapting to truss crossbeams of different lengths. The outer shell 2 protects the internal welding area, preventing welding sparks, slag spatter, and arc radiation leakage. The storage bin 4 provides centralized storage and continuous supply of crossbeam raw materials, ensuring subsequent continuous welding operations.

[0023] For further details, please refer to [link / reference]. Figure 3 The main beam positioning structure 5 includes a sliding seat 51 slidably mounted on the upper end of the machine base 1. A support plate 52 is fixedly mounted on the upper end of the sliding seat 51. A base 54 is rotatably connected to the inner surface of the support plate 52 through a resistance ring. Pipe fixing parts 55 for clamping the main beam are arranged in a ring on the side of the base 54 near the middle of the machine base 1. A clamping drive part 56 is provided in the inner cavity of the base 54 for driving the pipe fixing parts 55 to clamp and the base 54 to rotate. A chain belt 53 is provided on the side of the clamping drive part 56 away from the center of the machine base 1. The chain belt 53 is driven by a motor installed inside the sliding seat 51. The sliding seat 51 is the moving carrier of the main beam positioning structure 5. Driven by the electric telescopic rod, it slides smoothly along the upper end of the machine base 1 to complete the spacing adjustment. The support plate 52 provides a stable support and installation foundation for the base 54. The resistance ring between the support plate 52 and the base 54 has a preset damping effect. Its core function is to ensure that the clamping drive component 56 drives the pipe fixing component 55 to complete the clamping action of the main beam first, so as to avoid the base 54 rotating prematurely when the clamping is not stable, which would affect the positioning accuracy. Four pipe fixing components 55 are distributed in a ring on one side of the base 54, which can realize the simultaneous fixing of four main beams and ensure the consistency of the synchronous movement of multiple main beams. The clamping drive component 56 receives the power transmitted by the motor through the chain belt 53, and then realizes the clamping action of the pipe fixing component and the rotation action of the base synchronously. The chain belt 53 transmission has the characteristics of smooth power transmission and high transmission efficiency, which can ensure that the power is accurately transmitted to the clamping drive component 56.

[0024] For further details, please refer to [link / reference]. Figure 4The side beam welding structure 6 includes a guide rail 61 fixedly installed on the top wall of the inner cavity of the outer shell 2. An electric hoist 62 is slidably connected to the inner wall of the guide rail 61. A welding positioning component 64 is fixedly installed on the output side of the electric hoist 62. A feeding component 65 is fixedly installed at the rear end of the welding positioning component 64. A connecting groove 63 is opened on the top wall of the inner cavity of the outer shell 2, which communicates with the storage box 4 and is located at the starting point of the stroke of the feeding component 65.

[0025] In the operation of this embodiment, the truss is precisely and stably welded through the cooperation of the main beam positioning structure 5 and the side beam welding structure 6. In the main beam positioning structure 5, the sliding seat 51, together with the electric telescopic rod, can flexibly adapt to main beams of different lengths. The outer wall clamping component 552 and the inner wall support component 553 of the pipe fixing component 55 achieve double fixation of the main beam inside and outside, effectively avoiding welding offset deformation and improving positioning stability and accuracy. The resistance ring ensures that clamping takes priority over rotation, further ensuring the positioning effect. The chain belt 53 transmission ensures smooth power transmission. In the side beam welding structure 6, the guide rail 61, together with the electric hoist 62, enables flexible adjustment of the welding position. The feeding component 65 ensures orderly and accurate feeding of crossbeam raw materials. The welding positioning component 64 enables precise docking of the crossbeam and the main beam, helping to improve welding quality and work efficiency.

[0026] Example 2: Based on Example 1, this example ensures precise and stable positioning of the main beam through the cooperation of the clamping drive component 56 and the pipe fixing component 55. The transmission disk 561 of the clamping drive component 56 synchronously drives the gear ring 562 and the camshaft 563 to rotate, achieving precise power distribution. The meshing of the gear ring 562 and the gear 554 ensures that the power is smoothly transmitted to the outer wall clamping component 552 and the inner wall support component 553. The camshaft 563 cooperates with the arc groove 541 to achieve orderly rotation of the base 54. The outer wall clamping component 552 of the pipe fixing component 55 achieves precise clamping of the clamping plate 5521 through the reverse winding design of the cable 5524 and the winch 5525. The inner wall support component 553 achieves uniform support of the contact plate 5535 through the cooperation of the bidirectional screw 5532 and the cross slide 5533. The internal and external cooperation prevents the main beam from shifting and deforming, ensuring welding quality.

[0027] For further details, please refer to [link / reference]. Figure 5The clamping drive component 56 includes a transmission disk 561 rotatably mounted in the inner cavity of the base 54 and connected to the chain belt 53. A toothed ring 562 rotatably connected to the inner cavity of the base 54 is fixedly mounted on the side of the transmission disk 561 near the pipe fixing component 55. The toothed ring 562 meshes with the adjacent pipe fixing component 55. A camshaft 563 rotatably connected to the inner cavity of the base 54 is fixedly connected to the middle part of the side of the transmission disk 561 near the pipe fixing component 55. An arc-shaped groove 541 matching the maximum outer diameter of the camshaft 563 is opened in the inner cavity of the base 54. The path of the arc-shaped groove 541 is fan-shaped. The transmission disc 561 is the core component for power reception and distribution. After receiving power from the motor via the chain belt 53, it synchronously drives the gear ring 562 and camshaft 563 to rotate. The gear ring 562 transmits power to the pipe fixing component 55 through meshing to achieve the clamping action of the main beam. The camshaft 563 and the arc groove 541 are responsible for driving the base 54 to rotate. The fan-shaped path of the arc groove 541 can precisely limit the rotation angle range of the base 54, avoiding excessive rotation that affects the welding accuracy. With the cooperation of the resistance ring, the camshaft 563 needs to overcome the damping force on the inner wall of the arc groove 541 after the pipe fixing component 55 has completed the clamping action in order to drive the base 54 to rotate, ensuring the reasonable timing of the clamping and rotation actions.

[0028] For further details, please refer to [link / reference]. Figure 6 , Figure 7 and Figure 8 The pipe fastener 55 includes a chuck 551 fixedly installed on one side of the base 54. On the side of the chuck 551 away from the base 54, an outer wall clamping assembly 552 for clamping the outer surface of the truss main beam is arranged in a ring. On the side of the chuck 551 away from the base 54, an inner wall support assembly 553 for supporting the inner wall of the truss main beam is arranged. The inner cavity of the base 54 is provided with a gear 554 that meshes with the gear ring 562. The central shaft of the gear 554 extends into the inner cavity of the chuck 551 and is connected to the outer wall clamping assembly 552 and the inner wall support assembly 553 for transmission. The chuck 551 provides an integrated mounting carrier for the outer wall clamping assembly 552 and the inner wall support assembly 553, ensuring that the two assemblies move in unison. The gear 554, as a power transmission intermediary, synchronously transmits the rotational power of the gear ring 562 to the outer wall clamping assembly 552 and the inner wall support assembly 553, achieving synchronous action on the main beam from both inside and outside. This double-fixed structure can effectively prevent the main beam from shifting or deforming during welding, greatly improving the stability and accuracy of the main beam positioning, and providing a basic guarantee for the subsequent welding quality. The annularly distributed outer wall clamping assembly 552 can clamp the outer wall of the main beam evenly from the circumference, and together with the radial support of the inner wall support assembly 553, the main beam is subjected to balanced force.

[0029] For further details, please refer to [link / reference]. Figure 7The outer wall clamping assembly 552 includes a groove 5522 opened on the upper end of the chuck 551. A slider 5523 is slidably connected to the inner surface of the groove 5522. A clamping plate 5521 that is slidably connected to the upper end of the slider 5523 is fixedly connected to the upper end of the chuck 551. Winches 5525 that are symmetrically fixedly connected to the gear 554 are connected to the gear 554 in a transmission. A cable 5524 that is fixedly connected to the slider 5523 is wound around the outer surface of the two winches 5525. The two ends of the cable 5524 are wound in opposite directions to the adjacent winches 5525. When the gear 554 rotates under the action of the gear ring 562, the cable 5524 pulls the slider 5523 to slide in the groove 5522 under the winding action of the winches 5525. The slide groove 5522 provides precise guidance for the sliding of the slider 5523, ensuring that the slider 5523 drives the clamping plate 5521 to move smoothly in a preset direction. When the winch 5525 rotates with the gear 554, it pulls the slider 5523 through the cable 5524. Since the two ends of the cable 5524 are wound in opposite directions to the adjacent winch 5525, this winding method can keep the cable 5524 in a taut state at all times, which not only ensures the stability of power transmission, but also facilitates precise adjustment of the position of the slider 5523. This allows the clamping plate 5521 to accurately fit against the outer wall of the main beam for stable clamping. The coordinated action of multiple outer wall clamping components 552 can apply clamping force evenly from the circumference, avoiding excessive local force and damage to the main beam.

[0030] For further details, please refer to [link / reference]. Figure 8 The inner wall support assembly 553 includes a guide post 5531 installed on one side of the chuck 551. The inner surface of the guide post 5531 is rotatably connected to a bidirectional screw 5532 that is connected to the gear 554. The inner surface of the bidirectional screw 5532 is slidably connected to two cross slides 5533 that are threadedly connected to the bidirectional screw 5532. The outer surfaces of the two cross slides 5533 are rotatably connected to several connecting rods 5534 in a ring. The side of two adjacent connecting rods 5534 away from the guide post 5531 is rotatably connected to a contact plate 5535. When the bidirectional screw 5532 rotates, the two cross slides 5533 move closer to or further away from each other under the action of the thread, and the connecting rods 5534 drive the contact plate 5535 to move closer to or further away from the inner wall of the truss main beam. The guide post 5531 provides stable rotational support for the bidirectional screw 5532, ensuring that it does not deviate during transmission. The threaded design of the bidirectional screw 5532 enables the two cross slides 5533 to move closer or further apart synchronously. The connecting rod 5534 converts the linear motion of the cross slide 5533 into the radial motion of the contact plate 5535. When the contact plate 5535 contacts the inner wall of the main beam, it provides uniform support force and cooperates with the outer wall clamping assembly 552 to form double fixation inside and outside, effectively preventing the main beam from displacing due to heat deformation or external force during welding, and ensuring the welding accuracy.

[0031] Example 3: Based on Example 2, this example achieves precise feeding and efficient welding of the crossbeam through the cooperation of the feeding assembly 65 and the welding positioning assembly 64. The electric screw 655 of the feeding assembly 65 drives the push plate 653 to push the raw material, and the L-shaped plate 652 blocks the subsequent raw material to avoid feeding chaos and ensure orderly feeding. The guide plate 6433 of the welding positioning assembly 64 guides and the stop block 6435 limits the position, so as to achieve precise docking between the crossbeam and the main beam. The symmetrical plasma welding guns 6444 at the front and rear weld simultaneously to improve efficiency. The baffle 6445 avoids equipment collision and ensures stable and safe welding operation.

[0032] For further details, please refer to [link / reference]. Figure 9 The feeding assembly 65 includes a storage bin 651 installed at the rear end of the welding positioning assembly 64. A push plate 653 is slidably connected to the bottom wall of the inner cavity of the storage bin 651. An electric screw 655 threadedly connected to the push plate 653 is installed on the bottom wall of the inner cavity of the feeding assembly 65. A receiving groove 654 is opened at the lower rear part of the inner cavity of the storage bin 651. An L-shaped plate 652 is slidably connected to the inner surface of the receiving groove 654 by a spring. When the push plate 653 is in the inner wall of the receiving groove 654, the front end of the push plate 653 is flush with the rear side wall of the inner surface of the storage bin 651. When the push plate 653 moves forward under the action of the electric screw 655, the L-shaped plate 652 protrudes from the receiving groove 654 under the action of the spring. The guide rail 61 provides a horizontal sliding guide for the electric hoist 62, enabling the welding positioning component 64 to move smoothly along the guide rail 61, thus realizing welding operations on the connection seams of the main beam and crossbeam at different positions. The electric hoist 62 can drive the welding positioning component 64 to move up and down, adapting to welding needs at different heights, especially adjusting the height position when switching between welding the upper and lower main beams. The connecting groove 63 provides a raw material conveying channel between the storage box 4 and the feeding component 65, ensuring that the crossbeam raw material can accurately fall into the storage bin 651 of the feeding component 65. The storage bin 651 realizes single crossbeam The temporary storage and positioning of beam raw materials are achieved by an electric screw 655 driving a pusher plate 653 to move forward, thus accurately pushing the beam raw materials. When the pusher plate 653 pushes the materials, the L-shaped plate 652 protrudes from the receiving groove 654, which can prevent the subsequent beam raw materials in the storage bucket 651 from sliding forward, thus avoiding feeding chaos caused by multiple beam raw materials being sent out at the same time and ensuring the orderly feeding. When the pusher plate 653 resets, it squeezes the L-shaped plate 652 back into the receiving groove 654, making it easier for the subsequent beam raw materials to fall into the bottom of the storage bucket 651 for pushing. The spring provides power for the reset of the L-shaped plate 652.

[0033] For further details, please refer to [link / reference]. Figure 9The welding positioning assembly 64 includes a trolley 642, with a shielding cabinet 641 fixedly connected to its upper end. The upper end of the trolley 642 is equipped with a material feeding component 643 for conveying the crossbeams and a welding component 644 for welding the crossbeams. The rear end of the shielding cabinet 641 is fixedly connected to the front end of a storage bin 651 and communicates with the inner cavity of the storage bin 651. The trolley 642 provides an integrated installation platform for the material feeding component 643 and the welding component 644. Driven by an electric hoist 62, it slides and moves up and down along the guide rail 61. When the main beam is horizontal, the electric hoist 62 can drive the trolley 642 downwards to contact the two main beams above. Then, through the action of the guide rail 61, it moves horizontally on the main beams to complete the welding. The shielding cabinet 641 not only guides the material transfer between the feeding assembly 65 and the material feeding component 643, but also effectively shields the arc radiation generated during welding, reducing the impact on the surrounding environment and operators, and ensuring operational safety.

[0034] For further details, please refer to [link / reference]. Figure 10 The unloading component 643 includes four spring limit rods 6431 arranged in a rectangular pattern and mounted on the upper end of the traveling tractor 642. The outer surfaces of the four spring limit rods 6431 are slidably connected to a mounting plate 6432. Several guide plates 6433 are arranged and fixedly connected to the lower left and right sides of the mounting plate 6432. The side of the guide plates 6433 closest to the center of the mounting plate 6432 is rotatably connected to a support plate 6434 by a torsion spring. The upper end of the traveling tractor 642 has an unloading port that communicates with the lower end. The mounting plate 6432 is suspended above the unloading port. A stop block 6435 that limits the position of the crossbeam is fixedly connected to the upper end of the traveling tractor 642. Spring limit rod 6431 provides sliding guidance and elastic support for mounting plate 6432, ensuring that mounting plate 6432 can slide smoothly up and down and has a certain buffering performance. Guide plate 6433 plays a precise guiding role for the crossbeam material fed from shielding cabinet 641, preventing the material from deviating from the feeding path. Support plate 6434 can be flexibly flipped under the action of torsion spring, supporting the material when the crossbeam material is fed in, and flipping to release it when the feeding action is started, so that the crossbeam material can fall smoothly from the feeding port at the top of the crane 642 to the preset welding position of the main beam, realizing the precise docking of the crossbeam and the main beam. Stop block 6435 can limit the final stopping position of the crossbeam material, further ensuring the feeding accuracy.

[0035] For further details, please refer to [link / reference]. Figure 10The welding component 644 includes a lifting platform 6441. Cylinders mounted on the upper end of the crane 642 are provided on both the left and right sides of the lower end of the lifting platform 6441. A spring limiting rod 6442, which is fixedly connected to the mounting plate 6432, is slidably connected to the inner surface of the lifting platform 6441. Mounting rods 6443, which fit against both sides of the mounting plate 6432, are symmetrically fixedly connected to the lower end of the lifting platform 6441. Plasma welding guns 6444, which are used for welding the joint between the main beam and the crossbeam, are symmetrically fixedly connected to the two mounting rods 6443. A baffle 6445, which is higher than the plasma welding gun 6444, is fixedly connected to the side of the two mounting rods 6443 that is close to each other. The cylinder provides power for the lifting platform 6441 to rise and fall. By driving the lifting platform 6441 to fall, it drives the mounting plate 6432 to fall synchronously, thereby triggering the unloading action of the unloading component 6433. The spring limit rod 6442 can enhance the stability of the sliding of the mounting plate 6432 and also play a buffering role to avoid damage to the components due to hard contact. The mounting rod 6443 provides a stable mounting support for the plasma welding gun 6444. The plasma welding guns 6444, which are symmetrically arranged at the front and rear, can weld different positions of the joint at the same time, greatly improving welding efficiency. The baffle 6445 can not only block the sparks and slag generated during the welding process, preventing sparks and slag from damaging other parts of the equipment and protecting the safety of operators, but also prevent the plasma welding gun 6444 from colliding with the mounting plate 6432 due to excessive height, ensuring the operational safety of the welded components.
