[0002] With the continuous development of modern architecture and engineering projects, steel structures are being used more and more widely in fields such as buildings, bridges, and towers. Due to the advantages of steel structures such as high strength, light weight, and durability, their application in high-rise buildings and large-scale infrastructure is particularly prominent. However, there are many challenges in the installation and welding process of steel structures, especially in high-altitude environments. In order to improve construction efficiency and ensure construction safety, these challenges need to be addressed.

They often require complex operations or even extensive manual disassembly and reassembly, making it difficult to quickly adapt to different steel structure shapes, sizes, and welding position requirements. For example, when welding steel beams of different heights, adjusting the height may be time-consuming, or the required height may be difficult to achieve due to the fixed structure. They also do not provide sufficient support for welding requirements at different angles of steel structures, and it is often difficult to flexibly rotate or adjust the angle of the weldment. Forced adjustments may affect welding accuracy and quality, leading to welding defects. Utility Model Content

[0022] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0023] like Figures 1-4 As shown, this utility model provides a technical solution:

[0024] A prefabricated steel structure high-altitude welding auxiliary fixture, comprising:

[0025] The base 1 has a control panel 2 located on one front side of its upper surface. Four casters 3 are located at the four opposite corners of the lower surface of the base 1. A push rod 4 is located at the center of the rear end face of the base 1. Lifting structures 5 are located on both sides of the center of the upper surface of the base 1. A movable adjustment structure 6 is threaded between the two lifting structures 5. Sliding frames 7 are threaded on both sides of the center of the upper surface of the movable adjustment structure 6. A clamping and rotating structure 8 is located at the center of the upper surface of both sliding frames 7. The operator moves the clamp to the designated working position by holding the push rod 4, which in turn moves the casters 3. Once the clamp reaches the appropriate position, welding work can begin, meeting the different work requirements for high-altitude welding of steel structures.

[0026] The two lifting structures 5 include two lifting frames 501, which are respectively located at the center of the upper end face of the base 1. Each of the two lifting frames 501 has a first sliding groove 502 at the center of one side wall. Each of the two first sliding grooves 502 has a first lead screw 503 at its center. One end of each lead screw 503 passes through the lower inner wall of the two first sliding grooves 502, the lower inner wall of the two lifting frames 501, and the upper end face of the base 1, respectively, and connects to the lower end face of the base 1. Each lead screw 503 has a pulley 504 fixedly connected to its front end. A belt is fitted onto the outer wall of each pulley 504. A mounting bracket 505 is located near the center of the lower end face of the base 1. A first servo motor 506 is located at the center of the lower end face of the mounting bracket 505. The output end of the first servo motor 506 is fixedly connected to the mounting bracket 505. A protective shell 507 is provided at the center of the lower end face of the base 1 on one end of the pulley 504. When high-altitude welding is required, the pulley 504 connected to it is driven to rotate by starting the first servo motor 506. Since the two pulleys 504 are connected by a belt, they will rotate synchronously. The rotation of the pulley 504 causes the first lead screw 503 to rotate. The first lead screw 503 is threadedly engaged with the adjustment frame 601. The adjustment frame 601 will move up and down along the axis of the lead screw 503, thereby achieving the purpose of adjusting the working height of the fixture to adapt to different welding positions. It can effectively raise or lower the adjustment frame 601 to the required height and provide stable support. The protective shell 507 can prevent foreign objects from entering the connection structure and ensure the normal operation of the equipment.

[0027] The movable adjustment structure 6 includes an adjustment frame 601, which is threaded onto the outer walls of two first lead screws 503. A second slide groove 602 is provided at the center of the upper end face of the adjustment frame 601. A fixing plate 603 is provided at the center of the second slide groove 602. A second lead screw 604 is provided on both sides of the center of the second slide groove 602. A first turbine 605 is fixedly connected to one end of each of the two second lead screws 604. A cavity 607 is provided on both sides of the center of the lower end face of the adjustment frame 601. A stabilizing frame 609 is provided at the center of the lower end face of each of the two cavities 607. A second servo motor 608 is provided at the center of the interior of each of the two stabilizing frames 609. A second turbine 606 is fixedly connected to the output end of each of the two second servo motors 608. The two second turbines 606 mesh with the two first turbines 605 respectively. Two sliding frames 7 are threaded onto the outer walls of the two second lead screws 604 respectively.

[0028] Once the height is adjusted to the appropriate position, the second servo motor 608 is activated to drive the second turbine 606 to rotate. The second turbine 606 meshes with the first turbine 605, causing the first turbine 605 to rotate. The first turbine 605 is fixed to the second lead screw 604, so the second lead screw 604 rotates accordingly. As the second lead screw 604 rotates, the sliding frame 7 moves linearly on the second lead screw 604 due to the threaded engagement between the sliding frame 7 and the second lead screw 604. This allows for adjustment of the horizontal position between the two sliding frames 7 on the adjustment frame 601. The stabilizing frame 609 supports and protects the second servo motor 608, ensuring its stable operation and enabling more stable and accurate adjustment of the position between the two sliding frames 7.

[0029] The two clamping and rotating structures 8 include two rotators 801, which are respectively located at the center of the interior of the two sliding frames 7. Each rotator 801 has a clamping frame 802 fixedly connected to its output end. Each clamping frame 802 has a third sliding groove 803 at the center of its upper surface. A connecting plate 809 is located at the center of the interior of each third sliding groove 803. A third servo motor 804 is located near the upper center of the front surface of each clamping frame 802. The output ends of the two third servo motors 804 pass through the front surfaces of the two clamping frames 802 and the front surfaces of the two third sliding grooves 803, respectively, and connect to the two third sliding grooves 809. Inside the slide groove 803, and at each end, a third lead screw 805 is fixedly connected. One end of each of the two third lead screws 805 passes through the front end face of the two connecting plates 809 and extends to the rear end face of the two connecting plates 809. A fourth lead screw 806 is fixedly connected at each end. The threads between the two fourth lead screws 806 and the two third lead screws 805 are reversed. Clamping plates 807 are threaded onto the outer walls of the two fourth lead screws 806 and the two third lead screws 805. Anti-slip pads 808 are provided at the upper center of the rear end face of the two clamping plates 807 at the front and at the upper center of the front end face of the two clamping plates 807 at the rear.

[0030] Once adjusted to the appropriate position, the rotator 801 is activated to rotate the clamping frame 802, which in turn rotates the clamped steel workpiece, facilitating welding operations at different angles and improving the freedom and efficiency of welding work. Simultaneously, the third servo motor 804 is activated to rotate the third lead screw 805, which in turn rotates the fourth lead screw 806. Since the threads of the fourth lead screw 806 and the third lead screw 805 are opposite, the clamping plates 807 threaded on their outer walls will move towards or away from each other. When moving towards each other, the steel workpiece can be clamped; when moving away from each other, the workpiece is released. The anti-slip pad 808 increases friction to prevent the workpiece from sliding during welding, ensuring welding accuracy.

[0031] The working principle of this utility model is as follows: the operator holds the push rod 4 and pushes the clamp with universal wheels 3 to move it to the designated working position for high-altitude welding of steel structures. The flexibility of the universal wheels 3 facilitates quick and easy positioning of the clamp to meet the welding operation requirements of different positions. After reaching the designated position, if it is necessary to adjust the clamp to a suitable height for high-altitude welding operations, the first servo motor 506 is started. The output end of the first servo motor 506 drives the connected pulley 504 to rotate. Since the two pulleys 504 are connected by a belt, they rotate synchronously. The pulleys 504 drive the first lead screw 503 to rotate. Because the first lead screw 503 and the adjustment frame 601 are threadedly engaged, the adjustment frame 601 will move up and down along the axis of the first lead screw 503. It can raise or lower the adjustment frame 601 to the corresponding height according to the actual welding height requirements, while providing stable support for the entire upper structure. The protective shell 507 protects the connection structure at the center of the lower end face of the base 1, preventing foreign objects from entering and affecting the normal operation of the equipment.

[0032] After the height adjustment is completed, if it is necessary to adjust the horizontal position between the two sliding brackets 7, the second servo motor 608 is started. The output end of the second servo motor 608 drives the second turbine 606 to rotate. The second turbine 606 meshes with the first turbine 605, so the first turbine 605 will rotate accordingly. The first turbine 605 is fixedly connected to the second lead screw 604, and the second lead screw 604 rotates accordingly. At the same time, the sliding bracket 7 and the second lead screw 604 are threaded together, and the sliding bracket 7 will move linearly on the second lead screw 604. This achieves precise adjustment of the horizontal position between the two sliding brackets 7 on the adjustment frame 601. The stabilizing frame 609 is set at the center of the lower end face of the cavity 607. When the second servo motor 608 inside it is working, the stabilizing frame 609 plays a supporting and protective role, ensuring the stable operation of the second servo motor 608 and ensuring the stability and accuracy of the adjustment.

[0033] After the sliding frame 7 is adjusted to the appropriate position, the rotator 801 is started. The output end of the rotator 801 drives the clamping frame 802 connected to it to rotate, thereby allowing the clamped steel structure workpiece to rotate accordingly. This enables the operator to easily perform welding operations on the workpiece at different angles during the welding process, effectively improving the freedom and efficiency of the welding work. When the workpiece angle is adjusted or at any angle, it is necessary to clamp and fix the steel structure workpiece. This is done by starting the third servo motor 804 to drive the third lead screw 805 to rotate. The third lead screw 805 drives the fourth lead screw 806 to rotate. The opposite threads of the fourth lead screw 806 and the third lead screw 805 cause the clamping plates 807, which are clamped on the outer walls of the third lead screw 805 and the fourth lead screw 806, to move towards or away from each other. When moving towards each other, the clamping plates 807 tightly fit the steel structure workpiece and clamp it. When moving away from each other, the workpiece is released. At the same time, the anti-slip pad 808 increases the friction with the workpiece surface to prevent the workpiece from sliding during the welding process, thereby ensuring the accuracy of the welding work and the quality of the weld.

[0034] Furthermore, the control method of this utility model is controlled by the control panel 2. The control circuit of the control panel 2 can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Since this utility model is used to protect mechanical devices, the control method and circuit connection will not be explained in detail.

[0035] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
