Description

Technical Field

[0001] This invention relates to the field of steel structure assembly technology, specifically to a steel structure and its assembly structure. Background Technology

[0002] Steel structures are building structures made primarily of steel through processes such as hot rolling, cold bending, or welding. They offer advantages such as high strength, light weight, good seismic performance, and fast construction speed, and are widely used in industrial plants, high-rise buildings, bridges, and large-span spatial structures. Their core components include steel beams, steel columns, and steel trusses, which are welded together to form an overall load-bearing frame. Steel structure assembly and welding is a crucial step in construction, requiring the steel structures to be welded to be assembled first, followed by welding operations on the assembled steel structures.

[0003] When assembling existing steel structures, the two sets of steel structures are first joined together, and then the components are fixed with temporary bolts to ensure accurate positioning. After the assembly and joining are completed, welding is performed between the two sets of steel structures.

[0004] Before using temporary bolts to fix the position of the steel structure, the two sets of steel structures need to be initially joined together and then temporarily fixed with temporary bolts. However, after prolonged use, the increased wear of the temporary bolts can lead to insufficient tightening, causing misalignment during welding and resulting in lower final assembly accuracy. Although the steel structure can be stably joined and limited during welding, the sides of the steel structure cannot be effectively limited after joining and welding, making it difficult to control welding thermal deformation. This can lead to component twisting, misalignment, or weld displacement, directly affecting the structural dimensional accuracy and load-bearing performance, as well as safety during use. Furthermore, after welding, the welded steel structure cannot be automatically lifted and removed, increasing the workload of subsequent operations, reducing work efficiency, extending process intervals, and slowing down the overall construction progress, which is not conducive to more efficient operation in practice.

[0005] Furthermore, after assembling and welding the steel structure, it is necessary to raise the steel structure, which requires the use of multiple power sources for driving operations. It is not possible to perform various linkage operations through a single power source. This increases the complexity of assembling and welding the steel structure in reality, and the presence of multiple power sources also increases the corresponding maintenance costs.

[0006] Furthermore, dust accumulates on the work surface after prolonged use. It is impossible to clean the dust and impurities simultaneously when the steel structures are being connected and positioned, which will affect the assembly efficiency between the steel structures. The dust will also affect the quality of welding, which is not conducive to actual operation. Summary of the Invention

[0007] In view of the shortcomings of the prior art, the present invention provides a steel structure and an assembly structure of the steel structure, which has the advantages of using a single power source and providing greater convenience for the assembly and welding of the steel structure, thus solving the problems mentioned in the background art.

[0008] This invention provides the following technical solution: a steel structure and its assembly structure, comprising a base, an operating platform, and a fixing block. The upper surface of the base is fixedly installed with the bottom of the operating platform, and the bottom of the fixing block is fixedly installed with the top of the base. A lifting mechanism inside the fixing block connects and separates from the operating platform through a meshing force. The lifting mechanism is connected to a push-and-pull mechanism at its power end, which converts the pushing force into rotational force. The push-and-pull mechanism controls the lifting height of the lifting mechanism based on the magnitude of the pushing force. The lifting mechanism and the contacting and pushing mechanism together form an automated assembly mechanism.

[0009] Preferably, the abutting and pushing mechanism includes an electric slide rail, a T-shaped sliding block, a T-shaped mounting block, a bidirectional electric telescopic rod, a connecting slider, and a side clamping plate. The bottom of the electric slide rail is fixedly installed to the top of the operating table. The inside of the bottom end of the T-shaped sliding block is slidably connected to the outer surface of the electric slide rail. The bottom of the T-shaped mounting block is fixedly installed to the top of the T-shaped sliding block. The upper surface of the bidirectional electric telescopic rod is fixedly connected to the lower surface of the T-shaped mounting block. The back of the connecting slider is fixedly installed to one end of the bidirectional electric telescopic rod. The upper surface of the side clamping plate is fixedly connected to the lower surface of the connecting slider.

[0010] Preferably, the lifting mechanism includes a fixed rack, a screw, a connecting rod, and a connecting gear. The back of the fixed rack is fixedly installed to the front of the side clamping plate. The outer surface of the screw is rotatably connected to the interior of the fixed block. One end of the connecting rod is fixedly installed to one end of the screw. The interior of the connecting gear is fixedly installed to the outer surface of the connecting rod. A limit rod is fixedly installed on the upper surface of the base, and a receiving slider is slidably connected to the outer surface of the limit rod.

[0011] Preferably, the lower surface of the T-shaped sliding block is in contact with the upper surface of the operating table, and a through groove is provided inside the T-shaped sliding block, with the T-shaped mounting block disposed inside the through groove.

[0012] Preferably, an extension plate is fixedly installed on the right side of the T-shaped sliding block, and a steel structure body is placed on the upper surface of the extension plate. The back side of the lateral clamping plate abuts against the front side of the steel structure body.

[0013] Preferably, a second cleaning push plate is fixedly installed at the bottom of the extension plate, the lower surface of the second cleaning push plate is in contact with the upper surface of the operating table, and a first cleaning push plate is fixedly installed at the bottom of the second cleaning push plate, the lower surface of the first cleaning push plate is in contact with the upper surface of the base.

[0014] Preferably, the operating table has a collection groove 1 inside, the base has a collection groove 2 inside, and the base has mounting holes on all four sides.

[0015] Preferably, the outer surface of the screw is threadedly connected to a threaded lifting block, and the outer surface of one end of the threaded lifting block is slidably connected to the inner wall of the fixed block.

[0016] Preferably, a lifting plate is fixedly installed on the back of the threaded lifting block, and multiple sets of anti-slip grooves are evenly opened on the upper surface of the lifting plate, and the back of the lifting plate is fixedly installed with the front of the receiving slider.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. This type of steel structure and its assembly structure achieves linear and precise positioning of the steel structure body by driving T-shaped sliding blocks with electric slide rails. Combined with bidirectional electric telescopic rods pushing symmetrical clamping of the lateral clamping plates, the accuracy and quality of assembly are improved. Through the linkage design of cleaning push plates one and two, welding slag and debris on the operating table and base surface are cleaned simultaneously during component movement, thus solving the problem of synchronizing pushing and cleaning. This achieves the effect of cleaning while pushing, improving the linkage in actual operation and ensuring stability during welding, further enhancing the efficiency and effectiveness of assembly and welding.

[0018] 2. This type of steel structure and its assembly structure, through the meshing of connecting gears and fixed racks, can drive the welded steel structure body to rise for subsequent retrieval operations. The helical pair composed of screw and threaded lifting block has mechanical self-locking characteristics, which can maintain the load position unchanged even in the event of power failure. Combined with the bidirectional guide rail structure of limit rod and receiving slider, it ensures the stability of the lifting plate's rise, thus solving the problem of how to lift the welded steel structure body in a coordinated manner. It can achieve the effect of linkage between lifting and pushing, reducing the burden of subsequent retrieval, facilitating more efficient operation, and improving the linkage of the equipment during use.

[0021] 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.

[0022] Please see Figure 1 , Figure 4 and Figure 5 A steel structure and its assembly structure are disclosed, comprising a base 1, an operating platform 2, and a fixing block 17. The upper surface of the base 1 is fixedly installed to the bottom of the operating platform 2, and the bottom of the fixing block 17 is fixedly installed to the top of the base 1. A lifting mechanism provided inside the fixing block 17 connects and separates from the operating platform 2 through a meshing force. The power end of the lifting mechanism is connected to a contact and pushing mechanism that converts the pushing force into rotational force. The contact and pushing mechanism controls the lifting height of the lifting mechanism based on the magnitude of the pushing force. The lifting mechanism and the contacting and pushing mechanism together form an automated assembly mechanism. The contacting and pushing mechanism includes an electric slide rail 4, a T-shaped sliding block 5, a T-shaped mounting block 9, a bidirectional electric telescopic rod 10, a connecting slider 11, and a side clamping plate 12. The bottom of the electric slide rail 4 is fixedly installed to the top of the operating table 2. The inside of the bottom end of the T-shaped sliding block 5 is slidably connected to the outer surface of the electric slide rail 4. The bottom of the T-shaped mounting block 9 is fixedly installed to the top of the T-shaped sliding block 5. The upper surface of the bidirectional electric telescopic rod 10 is fixedly connected to the lower surface of the T-shaped mounting block 9. The back of the connecting slider 11 is fixedly installed to one end of the bidirectional electric telescopic rod 10. The upper surface of the side clamping plate 12 is fixedly connected to the connecting slider 4. The lower surface of block 11 is fixedly connected, the lower surface of T-shaped sliding block 5 is in contact with the upper surface of operating table 2, a through groove 8 is opened inside T-shaped sliding block 5, T-shaped mounting block 9 is set inside through groove 8, an extension plate 6 is fixedly installed on the right side of T-shaped sliding block 5, a steel structure body 7 is placed on the upper surface of extension plate 6, the back of side clamping plate 12 abuts against the front of steel structure body 7, a cleaning push plate 25 is fixedly installed at the bottom of extension plate 6, the lower surface of cleaning push plate 25 is in contact with the upper surface of operating table 2, a cleaning push plate 13 is fixedly installed at the bottom of cleaning push plate 25, and the lower surface of cleaning push plate 13 is in contact with the upper surface of base 1.

[0023] Specifically, the T-shaped mounting block 9 is fixed to the top of the T-shaped sliding block 5, and the T-shaped mounting block 9 is set in the through groove 8 inside the T-shaped sliding block 5, providing a stable installation foundation for the bidirectional electric telescopic rod 10, while ensuring the compactness and stability of the overall structure, achieving the effect of reasonable layout of each component and saving space. The T-shaped sliding block 5 slides stably and accurately in a straight line on the electric slide rail 4, achieving the effect of driving the upper component to move horizontally along the operating table 2, which facilitates the operation of the steel structure body 7 at different positions. When the bidirectional electric telescopic rod 10 extends and retracts, it can drive the side clamping plate 12 to move in opposite directions or back to back, achieving the flexible operation effect of side clamping or releasing the steel structure body 7 placed on the extension plate 6, meeting the fixing requirements of steel structures of different sizes. In addition, when in use, the steel structure body 7 is I-shaped steel. When the T-shaped sliding block 5 moves, the cleaning push plate 25 and the cleaning push plate 13 move accordingly, which can clean the debris on the surface of the operating table 2 and the base 1, achieving the effect of keeping the working environment clean and avoiding debris from affecting the assembly of the steel structure and the normal operation of the equipment. Furthermore, the electric slide rail 4 is driven by a servo motor and equipped with a precision reducer and a synchronous belt transmission system. It achieves high-precision positioning through PLC control. After receiving the control signal, the servo motor drives the ball screw in the guide rail through the synchronous belt pulley group, converting the rotational motion into the linear movement of the T-shaped sliding block (5). The body is made of hardened steel and is equipped with a pre-tightened ball slider to ensure load-bearing capacity and smooth movement. The bidirectional electric telescopic rod 10 is driven by a built-in stepper motor. It converts the rotational motion into the linear extension and retraction of the push rod through the worm gear. The motor receives instructions through the control board to achieve bidirectional synchronous or independent movement, pushing the connecting slider 11 and the side clamping plate 12 to clamp or release the steel structure body 7.

[0024] Please see Figure 6 and Figure 7 The lifting mechanism includes a fixed rack 16, a screw 18, a connecting rod 19, and a connecting gear 20. The back of the fixed rack 16 is fixedly installed on the front of the side clamping plate 12. The outer surface of the screw 18 is rotatably connected to the inside of the fixed block 17. One end of the connecting rod 19 is fixedly installed on one end of the screw 18. The inside of the connecting gear 20 is fixedly installed on the outer surface of the connecting rod 19. A limit rod 23 is fixedly installed on the upper surface of the base 1. A receiving slider 24 is slidably connected to the outer surface of the limit rod 23. A threaded lifting block 21 is threadedly connected to the outer surface of the screw 18. The outer surface of one end of the threaded lifting block 21 is slidably connected to the inner wall of the fixed block 17. A lifting plate 22 is fixedly installed on the back of the threaded lifting block 21. Multiple anti-slip grooves 26 are evenly opened on the upper surface of the lifting plate 22, and the back of the lifting plate 22 is fixedly installed on the front of the receiving slider 24.

[0025] Specifically, when the connecting gear 20 meshes with the fixed rack 16, it drives the screw 18 to rotate, thus converting the linear motion of the fixed rack 16 into the rotational motion of the screw 18. As the screw 18 rotates, the threaded lifting block 21 moves linearly up and down along the screw 18 under the action of the thread. Simultaneously, the fixed block 17 limits and guides the threaded lifting block 21, preventing it from rotating with the screw 18. This achieves the effect of converting the rotational motion of the screw 18 into the linear up and down motion of the threaded lifting block 21. The limiting rod 23 and the receiving slider 24 limit and guide the lifting plate 22, ensuring that the lifting plate 22 can only move in a straight line along the direction of the limiting rod 23. This ensures the accurate movement direction of the lifting plate 22 and prevents it from deviating. The lifting movement of the threaded lifting block 21 drives the lifting plate 22 to rise and fall synchronously. The multiple sets of anti-slip grooves 26 evenly distributed on the upper surface of the lifting plate 22 increase the friction between the lifting plate 22 and the object being lifted, thus stabilizing the lifting of the steel structure body 7 and preventing it from slipping during the lifting process. Furthermore, the connecting gear 20 and the fixed rack 16 are stably meshed through precision-machined involute tooth profiles. The module of the connecting gear 20 is strictly matched with that of the fixed rack 16, and the tooth backlash is controlled in the same way, so the continuity of meshing can be guaranteed when meshing is performed.

[0026] Please see Figure 1 , Figure 2 , Figure 3 The operating table 2 has a collection groove 14 inside, the base 1 has a collection groove 2 15 inside, and the base 1 has mounting holes 3 around its interior.

[0027] Specifically, the second collection trough 15 works in conjunction with the first collection trough 14 to achieve layered and comprehensive collection of debris from different locations, thereby expanding the debris collection range and making the entire working environment cleaner and more orderly. It keeps the surface of the operating table 2 clean, making subsequent cleaning easier and preventing debris from affecting the assembly accuracy of the steel structure and the work efficiency of the operators. By opening mounting holes 3 around the inside of the base 1, it provides a flexible and diverse installation method for the entire assembly equipment. The base 1 can be securely installed on different types of work site floors using connectors through the mounting holes 3.

[0028] Working principle: In use, firstly, the steel structure body 7 to be assembled is placed on the extension plate 6. Through the electrical connection of the external power source, the electric slide rail 4 can be activated to drive the T-shaped sliding block 5 to move along the operating table 2 to the predetermined position. At this time, the bidirectional electric telescopic rod 10 pushes the connecting slider 11 and the side clamping plate 12 to laterally clamp and position the steel structure body 7. At the same time, the fixed rack 16 moves synchronously with the side clamping plate 12. Then, the steel structure body 7 can be welded. After the steel structure body 7 is welded, the connecting rod 19 and the screw 18 can continue to rotate through the meshing of the connecting gear 20 and the fixed rack 16. When the screw 18 rotates, the threaded lifting block 21 is inside the fixed block 17. Vertical movement pushes the lifting plate 22 and the receiving slider 24 upward along the limiting rod 23. The limiting rod 23 ensures the vertical accuracy of the lifting trajectory. At this time, the anti-slip groove 26 is in direct contact with the welded steel structure body 7 to ensure the stability of the lifting process. During the lifting, the movement distance of the fixed rack 16 can be precisely controlled by the displacement of the electric slide rail 4, thereby adjusting the rotation angle of the screw 18, and finally realizing the digital control of the lifting height. This allows the welded steel structure body 7 to be raised for efficient handling. During the assembly process, the cleaning push plate 13 and the cleaning push plate 25 move with the extension plate 6, pushing the welding debris into the collection tank 14 and the collection tank 25 respectively to keep the working surface clean.
