Description

Technical Field

[0001] This invention belongs to the field of iron tower welding technology, specifically a welding and fixing fixture for iron tower steel structures. Background Technology

[0002] A welding and fixing fixture for steel tower structures is a device or tool used in the production and welding process of steel towers to ensure the precise positioning and fixation of various steel components. Due to the complex structure of steel towers, which typically include multiple vertical and inclined steel pipes and plates, precise positional control is crucial during welding. This fixture significantly improves welding accuracy and efficiency. This equipment is a vital production tool that ensures high efficiency, precision, and safety in the steel structure welding process through precise positioning and stable fixing. It not only improves production efficiency and reduces labor costs but also guarantees the quality of welded joints and extends the service life of the steel tower.

[0003] A welding and fixing fixture for steel tower structures, disclosed in prior art document CN117798587A, includes a fixture base. An auxiliary support mechanism is located at the top center of the fixture base. An adjusting base mechanism is located on one side of the top of the fixture base. A fixed base assembly is fixedly connected to the top of the fixture base at the end furthest from the adjusting base mechanism. Rotational adjustment mechanisms are installed on the tops of both the adjusting base mechanism and the fixed base assembly. Two supporting arm mechanisms are rotatably connected to each of the two rotational adjustment mechanisms. An adjustment drive mechanism is fixedly connected to the front end face of the top of both the adjusting base mechanism and the fixed base assembly. This invention designs two sets of supporting arm mechanisms and a movable steel pipe fixing mechanism within them, improving the overall applicability of the fixture and making it more accurate according to the scale indication. The equipment has a simple structure and low manufacturing cost.

[0004] While the aforementioned applications can broaden the applicability of the overall tooling, they typically only allow for fixed welding of steel pipes. When welding the base of a steel tower, welding is required at the joint between two steel plates. Existing technology can only weld joints between two steel plates of the same type. When the angle between the two steel plates needs to be adjusted, the existing equipment must be reconfigured, leading to a complex and time-consuming operation. Each angle change requires reconfiguration of the equipment, increasing working time and labor costs, and reducing the efficiency of subsequent welding at the joint between the two steel plates. Summary of the Invention

[0005] To address the problem mentioned in the background art that the angle between two steel plates cannot be freely adjusted, the present invention provides a welding and fixing fixture for steel tower structures.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a welding and fixing fixture for steel tower structures, comprising a workbench, two electric telescopic rods fixedly connected to both sides of the bottom inner wall of the workbench, four first limiting rods fixedly connected to the top four sides of the workbench, and a welding and fixing mechanism, the welding and fixing mechanism comprising a bearing frame plate fixedly connected to the top of the electric telescopic rods, the movable end of the electric telescopic rods penetrating the workbench and extending to the outside of the workbench, two first limiting rods arranged in a group, a square bar fixedly connected to the top of the group of first limiting rods, and rotating plates hinged to both sides of the bottom of the square bar, the rotating plates... A positioning component is installed at the bottom to clamp and position the two steel structure plates at an angle. The two steel structure plates are placed at an angle on the top of the workbench. The electric telescopic rod is activated, which drives the bearing frame plate to move vertically up and down on the outer wall of the first limit rod. The bearing frame plate drives the slider and L-shaped rod to move up and down. The L-shaped rod drives the positioning shell and positioning roller to move up and down. During the lifting and lowering process, the positioning roller can support the sides of the two inclined steel structure plates. Then, the welding machine is controlled to weld the joint of the two steel structure plates, ensuring that the sides of the steel plates are effectively supported and preventing positional displacement or deformation during the welding process.

[0007] Preferably, the positioning component includes a slider hinged to the bottom of the rotating plate, and sliding holes are provided on both sides of the top of the support frame plate, with one end of the slider slidably connected to the inner wall of the sliding hole.

[0008] Preferably, an L-shaped rod is fixedly connected to the side wall of the slider, and a positioning shell is fixedly connected to the end of the L-shaped rod away from the slider. The positioning shell is concave in shape.

[0009] Preferably, a positioning roller is rotatably connected to both sides of the inner wall of the positioning shell. When the support frame plate is vertically raised and lowered, the distance between the support frame plate and the square bar will move closer or further away. The resulting squeezing and traction forces cause the rotating plate to drive the slider to slide back and forth on the inner wall of the sliding hole opened at the top of the support frame plate. The slider drives the L-shaped rod and the positioning shell to move back and forth, and the positioning shell drives the positioning roller to move back and forth. During the movement of the positioning roller, the side of the steel plate is squeezed, thereby adjusting the angle between the two steel plates to ensure that the steel plates are at the correct relative angle during welding or assembly. This precise angle control is crucial for ensuring the stability of structural components, reducing errors, and improving assembly accuracy. Moreover, during the production process, the angle of the steel plate can be automatically adjusted according to the needs of different projects without manual intervention. This allows the production line to handle various types of welding tasks more flexibly, thereby expanding the types of welding projects and improving product diversity.

[0010] Preferably, the top of the workbench is provided with an auxiliary component, which includes four square plates fixedly connected to the top of the workbench, and two crossbars fixedly connected between two of the square plates.

[0011] Preferably, two blocks are slidably connected to the outer walls of both ends of the crossbar, one end of each block is hinged to a rotating bar, and the end of the rotating bar away from the block is hinged to a lifting bar.

[0012] Preferably, there are two lifting bars, and a second limiting rod is slidably connected to the inner wall of the lifting bar. The bottom of the second limiting rod is fixedly connected to the top of the worktable, and two vertical rods are fixedly connected to both sides of the top of the lifting bar.

[0013] Preferably, a round rod is fixedly connected between the two vertical rods, and a round roller is rotatably connected to the outer wall of the middle end of the round rod. Three triangular sleeves are fixedly connected to the outer wall of one end of the round roller.

[0014] Preferably, three reinforcing plates are fixedly connected to the outer wall of the triangular sleeve, and a traction rod is fixedly connected to the bottom of the slider.

[0015] Preferably, one end of the traction rod passes through the block and extends to the outside of the block.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention employs a welding and fixing mechanism to place two steel structural plates at an angle on the top of a workbench. Activating an electric telescopic rod causes the supporting frame plate to move vertically up and down on the outer wall of the first limiting rod. The supporting frame plate then moves the slider and L-shaped rod up and down, which in turn moves the positioning shell and positioning roller up and down. During this movement, the positioning roller supports the sides of the two inclined steel structural plates. Subsequently, a welding machine is used to weld the joint between the two steel structural plates, ensuring effective support for the sides of the steel plates and preventing positional shifts or deformations during welding. As the supporting frame plate moves vertically up and down, the distance between it and the square bar changes, generating pressure and traction. This causes a rotating plate to move the slider back and forth within a sliding hole on the top of the supporting frame plate. The slider then moves the L-shaped rod and positioning shell back and forth, which in turn moves the positioning roller back and forth. During this movement, the positioning roller compresses the sides of the steel plates, thereby adjusting the angle between the two plates and ensuring they are at the correct relative angle during welding or assembly. This precise angle control is crucial for ensuring the stability of structural components, reducing errors, and improving assembly accuracy. Furthermore, during production, the angle of the steel plate can be automatically adjusted according to the needs of different projects without manual intervention. This allows the production line to handle various types of welding tasks more flexibly, thereby expanding the range of welding projects and increasing product diversity.

[0017] This invention employs a welding and fixing mechanism. When two initially distant sliders approach each other, the sliders cause the blocks to slide along the outer wall of the crossbar. As the two blocks approach, the blocks drive the rotating and lifting bars to descend vertically along the outer wall of the second limiting bar. The lifting bars then drive the vertical and circular bars to descend, which in turn drive the circular roller and triangular sleeve frame to descend. The triangular sleeve frame then drives the reinforcing plate to descend vertically. During this descent, the reinforcing plate presses down on the sides of the two tightly fitted steel plates at their bottom ends. This vertical pressure from the reinforcing plate ensures a tighter fit between the two steel plates at their bottom ends. This pressing action guarantees a more uniform and gapless contact surface between the steel plates, thereby improving the bonding quality and reducing gaps or unevenness at the joints. Furthermore, since the reinforcing plate, triangular sleeve, and circular roller rotate freely on the outer wall of the circular rod, when the angle of the two steel plates is adjusted, the force generated by the deflection of the steel plates can make the contact surface of the reinforcing plate completely fit against the side wall of the steel plate. This allows the reinforcing plate to automatically adjust its posture as the steel plate deflects, ensuring that the contact surface of the reinforcing plate always maintains surface contact with the side wall of the steel plate, rather than point contact or edge contact. This improves the adaptive adjustment capability of the equipment and, in turn, enhances the welding accuracy of the subsequent welder on the steel plate. Attached Figure Description

Detailed Implementation

[0020] 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.

[0021] like Figures 1 to 6 As shown, the present invention provides a welding and fixing fixture for steel tower structures, including a workbench 1, two electric telescopic rods 2 fixedly connected to both sides of the bottom of the inner wall of the workbench 1, four first limiting rods 3 fixedly connected to the top of the workbench 1, and also includes; The welding and fixing mechanism 4 includes a support frame plate 41 fixedly connected to the top of the electric telescopic rod 2. The movable end of the electric telescopic rod 2 passes through the workbench 1 and extends to the outside of the workbench 1. Two first limiting rods 3 are arranged in a group. A square bar 42 is fixedly connected to the top of the group of first limiting rods 3. A rotating plate 43 is hinged to both sides of the bottom of the square bar 42. A positioning component 44 is provided at the bottom of the rotating plate 43 for clamping and positioning the two steel structure plates.

[0022] The above-mentioned scheme involves tilting and precisely placing two steel structural plates on top of workbench 1, ensuring the plates are in the correct position. Next, the electric telescopic rod 2 is activated, driving the support frame plate 41 to move vertically up and down along the outer wall of the first limiting rod 3. The support frame plate 41 drives the slider 442 and L-shaped rod 443 to rise together, and the L-shaped rod 443 further drives the positioning shell 444 and positioning roller 445 to adjust their height. During the lifting process, the positioning roller 445 plays a crucial role, evenly bearing the sides of the two tilted steel structural plates, ensuring the plates are stably fixed under appropriate pressure and preventing deformation or positional displacement due to uneven force. At this time, the positioning roller 445 not only provides strong support for subsequent welding but also ensures that the plates do not shift during the entire operation. Once the positioning roller 445 has completed its bearing, the welding control system is activated, performing precise welding at the joint of the two steel structural plates. During this process, the welding machine accurately aligns the welding positions, ensuring the stability and strength of the weld quality.

[0023] The positioning component 44 includes a slider 442 hinged to the bottom of the rotating plate 43. Sliding holes 441 are provided on both sides of the top of the support frame plate 41. The outer wall of one end of the slider 442 is slidably connected to the inner wall of the sliding hole 441.

[0024] An L-shaped rod 443 is fixedly connected to the side wall of the slider 442. A positioning shell 444 is fixedly connected to the end of the L-shaped rod 443 away from the slider 442. The positioning shell 444 is concave.

[0025] A positioning roller 445 is rotatably connected to both sides of the inner wall of the positioning shell 444.

[0026] The above scheme employs the following method: When the support frame plate 41 is vertically raised and lowered, the constantly changing distance between the support frame plate 41 and the square bar 42 generates extrusion and traction forces, causing the rotating plate 43 to drive the slider 442 to reciprocate along the inner wall of the sliding hole 441 at the top of the support frame plate 41. The movement of the slider 442 then drives the L-shaped rod 443 and the positioning shell 444 to reciprocate synchronously. The positioning shell 444, through its connection with the positioning roller 445, causes the positioning roller 445 to also reciprocate along a predetermined path. During the movement of the positioning roller 445, it applies uniform extrusion force to the side of the steel plate, thereby effectively controlling the angle between the two steel plates. Through precise pressure control, the positioning roller 445 can achieve fine-tuning between the plates, ensuring that the included angle between the two steel plates remains within the required range, thus providing a more stable foundation for subsequent welding or assembly.

[0027] like Figures 1 to 6As shown, an auxiliary component 45 is provided on the top of the workbench 1. The auxiliary component 45 includes four square plates 451 fixedly connected to the top of the workbench 1. Two crossbars 452 are fixedly connected between two square plates 451.

[0028] The above-mentioned scheme allows the reinforcing plate 4511, the triangular sleeve 4510, and the circular roller 459 to rotate freely on the outer wall of the circular rod 458. When the angle of the two steel plates is adjusted, the force generated by the deflection of the steel plates ensures that the contact surface of the reinforcing plate 4511 is fully in contact with the side wall of the steel plate. Through this mechanism, the reinforcing plate 4511 can automatically adjust its posture according to the deflection of the steel plates, ensuring that the contact surface of the reinforcing plate 4511 always maintains stable surface contact with the side wall of the steel plate, rather than just point contact or edge contact. This design greatly enhances the adaptive adjustment capability of the equipment, effectively coping with contact requirements under different angle changes. Surface contact allows for more uniform pressure distribution, avoiding excessive or insufficient local pressure caused by point or edge contact, thereby improving the accuracy and efficiency of the entire adjustment process and ensuring tight adhesion and stability between the steel plates.

[0029] Two blocks 453 are slidably connected to the outer walls of both ends of the crossbar 452. A rotating bar 454 is hinged to one end of the block 453, and a lifting bar 455 is hinged to the end of the rotating bar 454 away from the block 453.

[0030] There are two lifting bars 455. The inner wall of the lifting bar 455 is slidably connected to a second limiting rod 456. The bottom of the second limiting rod 456 is fixedly connected to the top of the worktable 1. Two vertical rods 457 are fixedly connected to both sides of the top of the lifting bar 455.

[0031] A round rod 458 is fixedly connected between the two vertical rods 457. A round roller 459 is rotatably connected to the outer wall of the middle end of the round rod 458. Three triangular sleeves 4510 are fixedly connected to the outer wall of one end of the round roller 459.

[0032] Three reinforcing plates 4511 are fixedly connected to the outer walls of the triangular sleeve 4510, and a traction rod 4512 is fixedly connected to the bottom of the slider 442.

[0033] One end of the traction rod 4512 passes through block 453 and extends to the outside of block 453.

[0034] The above scheme is adopted as follows: When the two sliders 442 approach each other, the sliders 442 drive the block 453 to slide along the outer wall of the crossbar 452. As the two blocks 453 gradually approach each other, they drive the rotating bar 454 and the lifting bar 455 to descend vertically along the outer wall of the second limit bar 456. The lifting bar 455 further drives the vertical bar 457 and the round bar 458 to descend together. The round bar 458 drives the round roller 459 and the triangular sleeve 4510 to move downward. The triangular sleeve 4510 finally drives the reinforcing plate 4511 to descend vertically. During the descent of the reinforcing plate 4511, a vertical downward pressure can be applied to the sides of the two steel plates that are tightly attached at the bottom. Through this vertical downward pressure, the contact surfaces of the two steel plates at the bottom are pressed more tightly together, enhancing the contact stability of the steel plates. This process ensures that the fastening and docking of the two steel plates is more secure, providing higher precision and stability, and providing a solid foundation for subsequent processing and welding.

[0035] Working principle and usage process of this invention: Two steel structure plates are placed at an angle on top of the workbench 1. The electric telescopic rod 2 is activated, which drives the bearing frame plate 41 to move vertically up and down on the outer wall of the first limit rod 3. The bearing frame plate 41 drives the slider 442 and the L-shaped rod 443 to move up and down. The L-shaped rod 443 drives the positioning shell 444 and the positioning roller 445 to move up and down. During the lifting and lowering process, the positioning roller 445 can support the sides of the two inclined steel structure plates. Then, the welding machine is controlled to weld the connection between the two steel structure plates to ensure that the sides of the steel plates are effectively supported and to prevent positional displacement or deformation during the welding process. When the support frame plate 41 is vertically raised and lowered, the distance between the support frame plate 41 and the square bar 42 will move closer or further apart. The resulting squeezing and traction forces cause the rotating plate 43 to drive the slider 442 to slide back and forth on the inner wall of the sliding hole 441 opened at the top of the support frame plate 41. The slider 442 drives the L-shaped rod 443 and the positioning shell 444 to move back and forth. The positioning shell 444 drives the positioning roller 445 to move back and forth. During the movement of the positioning roller 445, it squeezes the side of the steel plate, thereby adjusting the angle between the two steel plates to ensure that the steel plates are at the correct relative angle during welding or assembly. This precise angle control is crucial for ensuring the stability of structural components, reducing errors, and improving assembly accuracy. Moreover, during the production process, the angle of the steel plate can be automatically adjusted according to the needs of different projects without manual intervention. This allows the production line to handle various types of welding tasks more flexibly, thereby expanding the types of welding projects and increasing product diversity.

[0036] When two initially distant sliders 442 approach each other, the sliders 442 drive the block 453 to slide along the outer wall of the crossbar 452. As the two blocks 453 approach each other, the block 453 drives the rotating bar 454 and the lifting bar 455 to descend vertically along the outer wall of the second limit bar 456. The lifting bar 455 drives the vertical bar 457 and the round bar 458 to descend, and the round bar 458 drives the round roller 459 and the triangular sleeve 4510 to descend. The triangular sleeve 4510 drives the reinforcing plate 4511 to descend vertically. During the descent of the reinforcing plate 4511, it presses down on the sides of the two tightly fitted steel plates at their bottom ends. Through the vertical pressing action of the reinforcing plate 4511, the contact surfaces of the two steel plates at their bottom ends are pressed more tightly together. This pressing action ensures that the contact surfaces between the steel plates are more uniform and gapless, thereby improving the bonding quality of the steel plates and reducing gaps or unevenness at the joints. Furthermore, since the reinforcing plate 4511, the triangular sleeve 4510, and the circular roller 459 can rotate freely on the outer wall of the circular rod 458, when the angle of the two steel plates is adjusted, the force generated by the deflection of the steel plates can make the contact surface of the reinforcing plate 4511 completely fit against the side wall of the steel plate. This allows the reinforcing plate 4511 to automatically adjust its posture with the deflection of the steel plate, ensuring that the contact surface of the reinforcing plate 4511 always maintains surface contact with the side wall of the steel plate, rather than point contact or edge contact. This improves the adaptive adjustment capability of the equipment and, in turn, enhances the welding accuracy of the subsequent welder on the steel plate.
