Description

Technical Field

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

[0002] As one of the mainstream structural types in the field of building engineering, steel structure uses steel as its core construction material. Its system consists of key components such as steel beams, steel columns, and steel trusses. These components are all formed from steel raw materials such as shaped steel and steel plates through processes such as cutting, welding, and assembly. The joints of the various components of a steel structure are usually fastened by welds, bolts, or rivets to ensure the stability and load-bearing capacity of the overall structure. It is widely used due to its advantages such as light weight, high strength, and short construction period.

[0003] For example, in the prior art (Chinese patent with publication number CN118167056A), a steel structure docking device for steel structure construction is disclosed, including a column. A docking mechanism is provided on the outer periphery of the column. A crossbeam is provided on the upper part of one side of the docking mechanism. A servo motor drives the output gear to rotate, causing the clamping plate connected to it to rotate, thereby clamping both ends of the crossbeam. A second servo motor is driven to rotate, causing the drive gear to drive the driven gear to rotate, thereby allowing the threaded rod to move up and down. The threaded rod drives the intersecting end of the adjusting rod to move up and down, thereby causing the connecting rod to open and close. This causes the hub motor to fit against the inner wall of the column. The rotation of the hub motor housing allows the docking mechanism to move up and down relative to the column, thereby causing the crossbeam to move up and down. This facilitates docking the column and the crossbeam. Multiple devices can be used simultaneously to improve installation efficiency.

[0004] While the above-mentioned technical solution can achieve the assembly of multiple sets of steel beams on the sidewall of a steel column, it can only complete the installation and layout of multiple sets of steel beams at different heights on a single sidewall of the steel column by driving the steel beams to move up and down along the vertical direction of the steel column. However, it cannot meet the construction requirements of simultaneous installation of multiple sets of steel beams on all four sides of the steel column. Therefore, the above-mentioned existing solution has at least the following drawbacks:

[0005] 1. During construction, the position of the docking equipment needs to be adjusted multiple times, and the steel beams need to be assembled one side wall at a time, which increases the construction process and working time, and reduces the overall construction efficiency.

[0006] 2. Multiple orientation adjustments can easily lead to deviations in the installation benchmarks of the steel beams on each side wall, making it difficult to ensure the centering accuracy and consistency of the steel beams around the steel column relative to the steel column, thus affecting the overall stability and load-bearing capacity of the steel structure.

[0007] 3. For large factories, stadiums and other building scenarios that require steel beams to be arranged around the steel columns, the above-mentioned existing technical solutions cannot be directly adapted. Additional auxiliary positioning or steering devices are required, which increases construction costs and equipment investment, and may also increase construction safety hazards due to the coordinated operation of multiple devices. Summary of the Invention

[0008] To address the limitations of existing technologies, which can only install multiple sets of steel beams at different heights on a single sidewall of a steel column by driving the steel beams to move vertically along the column, but cannot meet the requirements of simultaneous installation of multiple sets of steel beams on all four sides of the column, this invention provides a steel structure construction docking device. This device can simultaneously center and align four sets of steel beams on all four sides of the steel column, ensuring the accuracy and consistency of the centering and docking of the four sets of steel beams relative to the column. Simultaneously, relying on the synchronous linkage performance of the drive system, it ensures that all steel beams are on the same height plane, overcoming the application limitations of traditional devices that can only position one side or in stages. The specific technical solution is as follows:

[0009] A steel structure construction docking device is used to dock four sets of steel beams on the four side walls of a steel column. The device includes a docking system, an assembly system, a drive system, and a connection system. The docking system comprises four sets, three of which are fixedly connected to form a U-shaped frame structure, while the remaining set is detachably disposed at the opening of the U-shaped frame structure. The assembly system is disposed below the four sets of docking systems and is detachably fitted onto the steel column. The drive system is disposed within the cavity of the assembly system and drives the four sets of docking systems to move synchronously, thereby achieving centered positioning of the four sets of steel beams on the four side walls of the steel column. The connection system is disposed on the side wall of the assembly system for the detachable connection of the assembly system onto the steel column.

[0010] Each docking system includes: a box and a limiting plate. The box is fitted to the side wall of the steel column. Two sets of limiting plates are symmetrically arranged along the length of the box. The two sets of limiting plates move towards each other to center and limit the steel beam at the side wall of the steel column. Each set of limiting plates moves synchronously under the drive of the driving system.

[0011] Each docking system further includes: a first guide groove, a guide rod, a moving block, a drive seat, a sliding pin, a U-shaped frame, and a drive arm. The first guide groove is opened above the box along the length direction of the box, and the limiting piece is slidably arranged along the inner cavity of the first guide groove. The guide rod is fixedly installed in the inner cavity of the box along the length direction of the box. Two sets of moving blocks are provided, which are symmetrically slidably sleeved on the guide rod. The top of each set of moving blocks is fixedly connected to the limiting piece at the corresponding position, and the bottom of each set of moving blocks is set as an inclined end face. The drive seat is fixedly and inclinedly installed at the inclined end face of each set of moving blocks, and a through groove is opened on the drive seat. The sliding pin is slidably embedded in the inner cavity of the through groove of the drive seat. The U-shaped frame is vertically and movable in the inner cavity of the box, and the sliding pin is installed on both sides of the top of the U-shaped frame. The top of the drive arm is fixedly installed on the lower surface of the U-shaped frame, and the bottom slides downward through the box, driving multiple sets of drive arms to descend synchronously, effectively avoiding the problem of lag or travel deviation of a single set of components.

[0012] In the above technical solution, each docking system further includes: an extension platform and an inclined support rod. The extension platform is vertically installed on the top of the outer wall of the box, and its upper surface is on the same plane as the upper surface of the box. The inclined support rod is inclined and fixedly installed between the extension platform and the box.

[0013] The limiting piece is provided with a notch adapted to the upper surface of the extension platform, and the limiting piece moves relative to the upper surface of the extension platform and the box.

[0014] In the above technical solution, the remaining docking system is detachably connected to the U-shaped frame structure formed by the three docking systems through a plug-in component. The plug-in component includes a plug and a sleeve. The plug is fixedly installed at the opening of the U-shaped frame structure and has a rectangular cross-section. The sleeve is fixedly installed on the side wall of the remaining docking system and the plug is inserted into the inner cavity of the sleeve.

[0015] In the above technical solution, the assembly system includes: a U-shaped shell, a second guide groove, a screw, a slider, a first limiting groove, a long shell, a second limiting groove, and a first vertical groove. The U-shaped shell is configured as a U-shaped cavity structure and fits snugly against the side wall of the steel column. The second guide groove is vertically opened on the side wall of the U-shaped shell. The screw is rotatably disposed in the inner cavity of the second guide groove, and its end extends downward through the outer wall of the U-shaped shell. The slider is threadedly connected to the screw and slides along the inner cavity of the second guide groove. Multiple sets of first limiting grooves are provided, each vertically opened on the inner side wall of the U-shaped shell. The long shell is detachably disposed at the opening of the U-shaped cavity structure of the U-shaped shell. Multiple sets of second limiting grooves are provided, each vertically opened on the inner side wall of the long shell. Two sets of first vertical grooves are provided, each symmetrically opened on the side wall of the long shell near the U-shaped shell.

[0016] In the above technical solution, the driving system includes: a U-shaped rod, a first block, a second vertical groove, a long rod, a second block, a first insertion hole, and an elastic element. The U-shaped rod is configured as a U-shaped structure and is vertically and movable within the inner cavity of the U-shaped housing. The U-shaped rod is fixedly connected to the slider, wherein the bottom ends of three sets of driving arms are fixedly connected to the U-shaped rod. Multiple sets of the first block are provided, respectively fixedly installed on the side wall of the U-shaped rod, and respectively slidably embedded in the inner cavity of the corresponding first limiting groove. Two sets of the second vertical groove are provided, respectively opened in the U-shaped housing. On the side wall near the long housing, the U-shaped rod passes through the inner cavity of the second vertical groove; the long rod is movable in the inner cavity of the long housing, and the remaining set of driving arms is fixedly connected to the long rod; multiple sets of second blocks are provided, respectively fixedly installed on the side wall of the long rod, and the second blocks are slidably embedded in the inner cavity of the second limiting groove; two sets of first insertion holes are provided, respectively opened at both ends of the long rod, and the U-shaped rod is pluggably embedded in the inner cavity of the first insertion hole; an elastic element is installed between the long rod and the inner wall of the bottom end of the long housing.

[0017] In the above technical solution, the U-shaped shell and the long shell are detachably connected by the connecting system. The connecting system has two sets, each set including: a first mounting base, a rod, a wedge, a spring, a second mounting base, a roller, a third mounting base, a rotating shaft, a rotating rod, a second insertion hole, a drive rod, a cover, and a coil spring. The first mounting base is fixedly installed on the side wall of the U-shaped shell; the rod is vertically movable and positioned at the top of the first mounting base; the wedge is inclined at the bottom end of the rod; the spring is sleeved on the rod and connected to both the outer wall of the rod and the outer wall of the first mounting base; the second mounting base is fixedly installed on the... The U-shaped housing sidewall; a roller rotatably mounted at the second mounting base; a third mounting base fixedly mounted on the long housing sidewall; a rotating shaft rotatably mounted on the insertion rod, with its top end extending upwards through the inner cavity of the insertion rod; a rotating rod fixedly mounted on the rotating shaft; a second insertion hole opened on the rotating rod, with the insertion rod and the wedge surface inserted into the inner cavity of the second insertion hole; a drive rod fixedly mounted on the sidewall of the rotating rod, with the roller sidewall rolling against the drive rod sidewall; a cover fixedly mounted on the top end of the insertion rod, with the top end of the rotating shaft extending into the inner cavity of the cover; a coil spring mounted in the inner cavity of the cover, with both ends connected to the rotating shaft and the inner wall of the cover, respectively.

[0018] In the above technical solution, the three sets of boxes and the U-shaped shell that make up the U-shaped frame structure are fixedly connected by connecting pieces, and the remaining set of boxes and the long shell are fixedly connected by connecting pieces.

[0019] In the above technical solution, a first anti-slip plate is installed on the side wall of the U-shaped shell and the long shell near the steel column, and a second anti-slip plate is installed on the side wall of the box body near the steel column.

[0020] In the above technical solution, the materials of the first anti-slip sheet and the second anti-slip sheet are selected from one or more of rubber-based composite materials, high wear-resistant engineering plastics, and anti-slip alloy steel with serrated surfaces.

[0021] The steel structure construction docking device of the present invention has the following advantages compared with the prior art:

[0022] I. Addressing the issue that existing solutions can only move steel beams vertically along the steel column to install multiple sets of steel beams at different heights on a single sidewall of the steel column, but cannot meet the requirements for simultaneous installation of multiple sets of steel beams on all four sides of the steel column, this invention utilizes a sliding pin that slides along the inclined groove of the drive seat to drive two sets of limiting plates to move towards each other. This allows for the simultaneous centering and alignment of four sets of steel beams on all four sides of the steel column, ensuring the accuracy and consistency of the centering and connection of the four sets of steel beams relative to the steel column. Furthermore, the synchronicity of the drive system ensures that all steel beams are on the same height plane, overcoming the limitations of traditional devices that can only position on one side or in stages. It eliminates the need for subsequent secondary adjustments to the position and height of the steel beams, directly providing a precise benchmark for the welding process, improving construction quality and efficiency. Moreover, it can be directly adapted to large factories, stadiums, and other building scenarios requiring steel beams to be installed on all four sides of the steel column, without the need for additional auxiliary positioning or steering devices, avoiding increased safety hazards due to the coordinated operation of multiple devices.

[0023] Second, this device uses a modular assembly structure to connect with the steel column, rather than the traditional whole-piece installation method. This method allows for rapid assembly and disassembly of the device at different heights on the steel column, eliminating the need to slide the device entirely onto the top of the column. This avoids the drawbacks of the whole-piece installation method, which is limited by construction space and obstacles at the top of the steel column. Construction personnel can directly assemble the device on-site at the target construction location. In addition, after assembly, the device can be locked at any construction point at any height along the vertical direction of the steel column, adapting to the operational needs of different floor heights and different construction sections. It also simplifies the high-altitude operation process, reduces the operation steps of hoisting and relocating the device, and improves the turnover rate of the device, meeting the needs of continuous construction in multiple batches and locations.

[0024] Third, in this invention, a U-shaped frame is formed by three sets of docking systems on the front side, and a set of docking systems on the rear side utilizes the fitting and cooperation of sleeves and plugs to achieve a quick snap-fit ​​preliminary assembly of the device and the steel column. Without the need for complex auxiliary positioning tools, the device can be fitted and arranged around the steel column, shortening the assembly preparation time. Through the close assembly of the U-shaped shell and the long shell, the automatic linkage connection of the U-shaped rod and the long rod is automatically realized. At the same time, the connection system automatically locks the U-shaped shell and the long shell, thereby realizing the full-angle limit locking after the three sets of boxes and the remaining set of boxes are assembled on the steel column. The above steps are only achieved during the assembly process of the long shell close to the U-shaped shell, without the need for additional operation steps. The overall assembly operation steps are simple and convenient, saving the overall construction cycle of steel structure docking.

[0025] IV. This invention uses the linkage between the drive rod and the roller to drive the insertion rod into the second insertion hole, and the spring elastic reset to drive the insertion rod. The automatic embedding and locking of the connection node is triggered by the displacement of the components, without the need for manual tightening. After locking, the rotating rod is subject to multiple limits by the inner wall of the first mounting seat and the insertion rod, which effectively prevents the connection from loosening and ensures the structural stability of the device under construction load. This solves the problem of loosening and falling off that is easy to occur in traditional bolt connections.

[0026] Fifth, this invention establishes a synchronous driving linkage between the U-shaped shell and the long shell through the insertion and cooperation of the U-shaped rod and the first insertion hole, so as to realize the synchronous downward movement of multiple sets of driving arms, avoid the lag or amplitude deviation of the movement of a single set of components, and achieve the synchronous alignment and adjustment of four sets of steel beams. This solves the defect of traditional devices that are difficult to achieve synchronous centering of multiple sets of components, and at the same time improves the consistency and accuracy of multi-station construction docking.

[0027] VI. This device achieves semi-automated operation from device assembly and locking to component positioning through the linkage and coordination of various systems, eliminating the need for multiple people to work together for repeated positioning and adjustment; reducing errors caused by manual intervention, shortening the construction cycle, and solving the problems of low efficiency and large error in traditional manual positioning.

[0028] In summary, this invention achieves the functional advantages of each technical point through the coordinated operation of a modular assembly structure, an automatic trigger locking system, and a full-process synchronous drive mechanism. Simultaneously, it forms a highly efficient operation mode encompassing assembly, positioning, disassembly, and turnover. Compared to traditional steel structure docking devices, this invention can achieve high-precision synchronous alignment of steel beams around a steel column without large auxiliary equipment or extensive human intervention. Furthermore, the assembly, disassembly, and transfer of the device do not rely on the operating space at the top of the steel column, making it suitable for complex construction environments such as high-altitude and confined spaces. At the same time, the linkage design of automatic locking and synchronous drive reduces the impact of human error on construction quality, achieving a dual improvement in construction efficiency and docking accuracy. It effectively solves the defects of difficult positioning and low efficiency in traditional construction, providing an integrated solution for the rapid construction of steel structure projects such as large stadiums and factories.

[0047] The following are specific implementation cases and appendices. Figures 1 to 16 The present invention will be further described, but the present invention is not limited to these embodiments.

[0048] Main references Figures 1 to 4 As shown, a steel structure construction docking device is used to dock four sets of steel beams 2 on the four side walls of a steel column 1. It includes a docking system 3, an assembly system 5, a drive system 6, and a connection system 7. The docking system 3 has four sets, three of which are fixedly connected by angle steel connecting plates and bolts to form a U-shaped frame structure. The remaining set of docking systems 3 is detachably installed at the opening of the U-shaped frame structure. After the four sets of docking systems 3 are assembled, a preliminary assembly state is formed on the side walls of the steel column 1. The assembly system 5 is located below the four sets of docking systems 3, and... The detachable fitting sleeve is attached to the steel column 1; the docking system 3 and the assembly system 5 are both attached to the steel column 1 to achieve the connection of the whole device on the steel column 1, which provides the basis for the subsequent synchronous centering and limiting of the four sets of steel beams 2 on the four sides of the steel column 1 and subsequent construction; the drive system 6 is set in the cavity of the assembly system 5 to drive the four sets of docking systems 3 to move synchronously, so as to achieve the centering and limiting of the four sets of steel beams 2 on the four sides of the steel column 1 respectively; the connection system 7 is set in the side wall of the assembly system 5 for the detachable connection of the assembly system 5 on the steel column 1;

[0049] Each docking system 3 includes a box 301 and a limiting plate 305. The box 301 is fitted to the side wall of the steel column 1. Two sets of limiting plates 305 are symmetrically arranged along the length of the box 301. The two sets of limiting plates 305 move towards each other to center and limit the steel beam 2 at the side wall of the steel column 1. Each set of limiting plates 305 moves synchronously under the drive of the drive system 6.

[0050] In this invention, two sets of limiting plates 305 move towards each other, enabling the centering and alignment of four sets of steel beams 2 around the sidewalls of the steel column 1 in one go, ensuring the accuracy and consistency of the centering and docking of the four sets of steel beams 2 relative to the steel column 1. Simultaneously, relying on the synchronous linkage performance of the drive system, it ensures that all steel beams 2 are on the same height plane, breaking through the application limitations of traditional devices that can only position on one side or in stages. Furthermore, this solution eliminates the need for secondary adjustments to the position and height of the steel beams 2, directly providing a precise positioning benchmark for subsequent welding processes, effectively improving construction quality and work efficiency. In addition, this solution can be directly adapted to large factories, stadiums, and other architectural scenarios requiring the placement of steel beams around steel columns, without the need for additional auxiliary positioning or steering devices, avoiding construction safety hazards introduced by the collaborative operation of multiple devices.

[0051] Furthermore, in this invention, the assembly is performed by a rear-side docking system 3 approaching the front three docking systems 3, and combined with the assembly of the assembly system 5. All assembly methods employ a modular assembly approach, rather than a set-like method. That is, this device abandons the traditional integrated installation method, adopting a modular structure to connect with the steel column 1. This assembly method allows for rapid installation and disassembly of the device at different heights on the steel column 1, eliminating the need to slide the device entirely onto the top of the steel column 1. This effectively avoids the technical drawbacks of integrated installation, such as limited construction space and obstacles at the top of the steel column 1. Construction personnel can directly complete the on-site assembly of the device at the target construction height.

[0052] Main references Figures 3 to 6 , Figure 8 and Figure 9As shown, each docking system 3 further includes: a first guide groove 302, a guide rod 303, a moving block 304, a drive seat 306, a sliding pin 307, a U-shaped frame 308, and a drive arm 309. The first guide groove 302 is opened above the housing 301 along the length direction of the housing 301, and the limiting piece 305 is slidably arranged along the inner cavity of the first guide groove 302. The guide rod 303 is fixedly installed in the inner cavity of the housing 301 along the length direction of the housing 301. Two sets of moving blocks 304 are provided, which are symmetrically slidably sleeved on the guide rod 303. The top of each set of moving blocks 304 is respectively connected to the guide rod 303. The corresponding limiting piece 305 is fixedly connected, and the lower part of each group of moving blocks 304 is set as an inclined end face; the drive seat 306 is fixed and inclinedly installed on the inclined end face of each group of moving blocks 304, and a through groove is opened through the drive seat 306; the sliding pin 307 is slidably embedded in the cavity of the through groove of the drive seat 306; the U-shaped frame 308 is set in the cavity of the box 301 for lifting and moving, and the sliding pin 307 is installed on both sides of the top of the U-shaped frame 308; the top of the drive arm 309 is fixedly installed on the lower surface of the U-shaped frame 308, and the bottom end slides downward through the box 301.

[0053] Multiple sets of drive arms 309 descend synchronously, driving the U-shaped frame 308 and the sliding pins 307 on both sides of the top to move along the inclined through groove of the drive seat 306. This, in turn, drives the drive seat 306 and the moving block 304 to move closer to the center of the guide rod 303, causing the two sets of limiting plates 305 to move towards each other. This linkage action allows the steel beam 2 to automatically center and align relative to the side wall of the steel column 1, ultimately achieving synchronous centering and limiting of the four sets of steel beams 2 at the same height around the steel column 1, providing a foundation for subsequent welding operations.

[0054] Main references Figures 3 to 5 As shown, each docking system 3 also includes an extension platform 311 and an inclined support rod 310. The extension platform 311 is vertically installed on the top of the outer wall of the box 301, and its upper surface is on the same plane as the upper surface of the box 301. The inclined support rod 310 is inclined and fixedly installed between the extension platform 311 and the box 301. By extending the extension platform 311 laterally relative to the box 301, a more stable limiting and auxiliary support capacity is provided for the steel beam 2 to be placed on the extension platform 311. Combined with the lifting effect of existing market lifting devices on the steel beam 2, it can ensure that the end of the steel beam 2 is more accurately centered and limited on the side wall of the steel column 1.

[0055] In addition, the main references Figure 2 As shown, the limiting piece 305 is provided with a notch adapted to the upper surface of the extension platform 311, and the limiting piece 305 moves relative to the upper surface of the extension platform 311 and the box 301. This ensures that the contact area of ​​the limiting piece 305 with the side wall of the steel beam 2 is sufficient to enable the limiting piece 305 to play a more accurate limiting and docking role with the side wall of the steel beam 2, while also not affecting the displacement of the limiting piece 305 relative to the upper surface of the extension platform 311.

[0056] Main references Figure 2 , Figure 6 As shown, the remaining docking system 3 is detachably connected to the U-shaped frame structure formed by the three docking systems 3 fixedly connected by the plug-in assembly 4. The plug-in assembly 4 includes: a plug block 401 and a sleeve 402. The plug block 401 is fixedly installed at the opening of the U-shaped frame structure and its cross-section is rectangular. The sleeve 402 is fixedly installed on the side wall of the remaining docking system 3, and the plug block 401 is inserted into the inner cavity of the sleeve 402. When the U-shaped frame structure formed by the fixed connection of the three docking systems 3 on the front side is attached to the front side wall and the left and right side walls of the steel column 1, the inner side wall of the U-shaped shell 501 below the three sets is also attached to the front side wall and the left and right side walls of the steel column 1. When the remaining docking system 3 on the rear side is brought closer to the three docking systems 3 on the front side, the sleeve 402 is fitted onto the plug block 401, thus realizing the initial assembly of the rear box 301 with the three boxes 301 on the front side.

[0057] After the sleeve 402 is fitted onto the insert block 401, it can limit the rear set of boxes 301 in the vertical and horizontal directions relative to the other three sets of boxes 301. Through subsequent assembly by the assembly system 5, it completely locks the rear set of boxes 301 in the front-rear direction relative to the other three sets of boxes 301. In this invention, the front three sets of docking systems 3 are spliced ​​to form a U-shaped frame, which is then connected to the rear set of docking systems 3 via the sleeve 402 and insert block 401 fitting structure. This allows for quick snap-fit ​​initial assembly of the device with the steel column 1. This assembly method eliminates the need for complex auxiliary positioning tools, enabling the device to precisely fit against the four sides of the steel column 1, thus shortening the assembly preparation time.

[0058] Main references Figures 6 to 13As shown, the assembly system 5 includes: a U-shaped housing 501, a second guide groove 502, a screw 503, a slider 504, a first limiting groove 505, a long housing 506, a second limiting groove 507, and a first vertical groove 508. The U-shaped housing 501 is configured as a U-shaped cavity structure and fits snugly against the side wall of the steel column 1. The second guide groove 502 is opened vertically on the side wall of the U-shaped housing 501. The screw 503 is rotatably mounted in the inner cavity of the second guide groove 502 via a bearing, and its end extends downward through the outer wall of the U-shaped housing 501. The screw 503 is a screw component with a self-locking function available in the market. When it stops rotating, it can achieve self-locking through its own structural characteristics to avoid displacement or rotation due to external forces, ensuring the positional accuracy during equipment operation. The thread parameters processed on the screw surface, including pitch, lead, and material friction coefficient, all adopt existing mature technical standards and do not require special design. Given that its structure and function conform to existing technology and are suitable for the application scenario, its specific dimensions, materials, and other details will not be elaborated or limited here. The slider 504 is threadedly connected to the screw 503 and slides along the inner cavity of the second guide groove 502; multiple sets of first limiting grooves 505 are provided, which are respectively opened vertically on the inner side wall of the U-shaped housing 501; the long housing 506 is detachably set at the opening of the U-shaped cavity structure of the U-shaped housing 501; multiple sets of second limiting grooves 507 are provided, which are respectively opened vertically on the inner side wall of the long housing 506; two sets of first vertical grooves 508 are provided, which are respectively symmetrically opened on the side wall of the long housing 506 near the U-shaped housing 501.

[0059] Main references Figure 8 , Figure 9 , Figures 11 to 13As shown, the drive system 6 includes: a U-shaped rod 601, a first block 602, a second vertical groove 603, a long rod 604, a second block 605, a first insertion hole 606, and an elastic element 607. The U-shaped rod 601 is configured as a U-shaped structure and is vertically and movable within the cavity of the U-shaped housing 501. The U-shaped rod 601 is fixedly connected to the slider 504. The bottom ends of three sets of drive arms 309 are fixedly connected to the U-shaped rod 601. Multiple sets of first blocks 602 are provided, respectively fixedly installed on the side wall of the U-shaped rod 601, and respectively slidably embedded in the cavity of the corresponding first limiting groove 505. Two sets of second vertical grooves 603 are provided, respectively opened in the U-shaped housing. 501 is located on the side wall near the long housing 506, and the U-shaped rod 601 passes through the inner cavity of the second vertical groove 603; the long rod 604 is movable in the inner cavity of the long housing 506, and the remaining set of drive arms 309 is fixedly connected to the long rod 604; multiple sets of second blocks 605 are provided, which are fixedly installed on the side wall of the long rod 604, and the second blocks 605 are slidably embedded in the inner cavity of the second limiting groove 507; two sets of first insertion holes 606 are provided, which are respectively opened at both ends of the long rod 604, and the U-shaped rod 601 is pluggably embedded in the inner cavity of the first insertion hole 606; the elastic element 607 is installed between the long rod 604 and the inner wall of the bottom end of the long housing 506. The elastic element 607 is a commercially available general-purpose elastic element, consisting of a spring and annular seats installed at both ends of the spring. Under the action of external force, the total length of the elastic element 607 can change, and the spring force can realize the return of the telescopic rod to its original position without external force. The elastic element 607 only needs to meet the usage requirements of this application, and the model of the above-mentioned existing components will not be limited or described in detail here. During the initial movement of the long rod 604 toward the U-shaped rod 601, the U-shaped rod 601 is inserted into the inner cavity of the first insertion hole 606. At this time, the elastic element 607 is not compressed. Under the action of the downward driving force of the U-shaped rod 601, the long rod 604 is forced to compress and deform, that is, the elastic element 607 can provide power for the long rod 604 to return to its initial position in the vertical direction after the U-shaped rod 601 is removed from the inner cavity of the first insertion hole 606.

[0060] During the assembly of the long shell 506 and the U-shaped shell 501, the two free ends of the U-shaped rod 601 are inserted into the inner cavity of the first insertion hole 606 on the long rod 604. That is, by moving the U-shaped rod 601 vertically within the inner cavity of the U-shaped shell 501, the long rod 604 can simultaneously move vertically along the inner cavity of the long shell 506. This invention utilizes the insertion and engagement of the U-shaped rod 601 and the first insertion hole 606 to achieve a synchronous drive linkage structure between the U-shaped shell 501 and the long shell 506, driving multiple sets of drive arms 309 to move synchronously downwards, effectively avoiding the problem of lag or travel deviation in the movement of a single component. This linkage design can drive four sets of steel beams 2 to complete the alignment adjustment synchronously, solving the defect of traditional devices that cannot achieve synchronous centering of multiple components, and improving the consistency and accuracy of multi-station construction docking.

[0061] Main references Figures 11 to 16 As shown, the U-shaped housing 501 and the long housing 506 are detachably connected by a connecting system 7. The connecting system 7 has two sets, each set including: a first mounting base 701, a rod 702, a wedge surface 703, a spring 704, a second mounting base 705, a roller 706, a third mounting base 707, a rotating shaft 708, a rotating rod 709, a second insertion hole 710, a drive rod 711, a cover 712, and a coil spring 713. The first mounting base 701 is fixedly mounted on the side wall of the U-shaped housing 501; the rod 702 is vertically movable and positioned at the top of the first mounting base 701; the wedge surface 703 is inclined at the bottom end of the rod 702; and the spring 704 is sleeved on the rod 702. The first mounting base 705 is fixedly installed on the side wall of the U-shaped housing 501, and the second mounting base 705 is connected to the outer wall of the insertion rod 702 and the outer wall of the first mounting base 701, respectively. The roller 706 is rotatably mounted on the second mounting base 705. The third mounting base 707 is fixedly mounted on the side wall of the long housing 506. The rotating shaft 708 is rotatably mounted on the insertion rod 702 through a bearing, and its top end extends upward through the inner cavity of the insertion rod 702. The rotating rod 709 is fixedly installed on the rotating shaft 708. The second insertion hole 710 is opened on the rotating rod 709, and the insertion rod 702 and the wedge surface 703 are inserted into the inner cavity of the second insertion hole 710. The drive rod 711 is fixedly installed on the side wall of the rotating rod 709, and the side wall of the roller 706 rolls against the side wall of the drive rod 711. (See main references) Figure 13 As shown, when the long housing 506 is not assembled with the U-shaped housing 501 and is in its natural state, the free end of the drive rod 711 is located between the roller 706 and the outer wall of the U-shaped housing 501. This ensures that when the first mounting base 701 moves close to the insertion rod 702, the roller 706 can drive the drive rod 711 to rotate around the pivot 708, thereby enabling the pivot 709 to move towards the inner cavity of the first mounting base 701. The cover 712 is fixedly installed on the top of the insertion rod 702, and the top of the pivot 708 extends into the inner cavity of the cover 712. The coil spring 713 is installed in the inner cavity of the cover 712, and its two ends are connected to the pivot 708 and the inner wall of the cover 712, respectively.

[0062] During the assembly of the rear housing 301 with the three sets of front housings 301, the long shell 506 at the bottom of the rear housing 301 moves synchronously towards the U-shaped shell 501. During the displacement, the free end of the drive rod 711 contacts the roller 706 and rotates around the pivot 708, causing the rotating rod 709 to move towards the inner cavity of the first mounting base 701. At the same time, the coil spring 713 undergoes torsional deformation, and the wedge surface 703 moves upward, compressing the spring 704. When the rotating rod 709 is fully embedded in the inner cavity of the first mounting base 701, the spring 704 elastically resets, driving the insertion rod 702 downward, causing the wedge surface 703 to insert into the inner cavity of the second insertion hole 710. At this time, the rotating rod 709 is subject to multiple constraints from the inner wall of the first mounting base 701 and the side wall of the insertion rod 702, achieving a stable connection between the long shell 506 and the U-shaped shell 501, thereby completing the assembly of the assembly system 5 and the docking system 3 on the steel column 1. Furthermore, the friction and stability of the device mounted on the steel column 1 can be further enhanced by using the first anti-slip plate 9 on the side wall of the U-shaped shell 501 and the long shell 506, and the second anti-slip plate 10 on the side wall of the box 301.

[0063] This invention relies on the contact transmission between the drive rod 711 and the roller 706, and the linkage mechanism of the spring 704 elastically returning and driving the insertion rod 702 into the second insertion hole 710. The displacement process of the components automatically triggers the embedding and locking of the connection node, eliminating the need for manual tightening. After locking, the rotating rod 709 is subject to multiple limiting constraints from the inner wall of the first mounting base 701 and the insertion rod 702, effectively preventing loosening and displacement of the connection node, ensuring the structural stability of the device under construction loads, and completely solving the defects of loosening and falling off in traditional bolted connections.

[0064] In addition, the overall disassembly process of this device is as follows: simply pull the insertion rod 702 upwards, and with the help of the torsional reset force of the coil spring 713, drive the rotating shaft 708 to rotate the rotating rod 709 and disengage it from the inner cavity of the first mounting base 701; during this process, the second insertion hole 710 simultaneously releases the limiting engagement relationship with the insertion rod 702 and the wedge surface 703, thereby realizing the separation and unlocking of the first mounting base 701 and the insertion rod 702, achieving the disassembly and separation of the long shell 506 and the U-shaped shell 501; finally, the rear box 301 and the three sets of front boxes 301 are disassembled, completing the overall disassembly and separation of this device from the steel column 1.

[0065] In this invention, the assembly process of the long shell 506 and the U-shaped shell 501 can be automatically triggered and locked by the connection system 7. That is, the locking connection between the two can be automatically completed as the long shell 506 approaches the U-shaped shell 501, without the need for additional operation steps, thus simplifying the assembly process. In the disassembly stage, only the single action of pulling out the plug rod 702 upwards is required to trigger the subsequent unlocking and disassembly actions, without the need for complex auxiliary tools, effectively reducing the difficulty of disassembly operations and shortening the disassembly time. At the same time, relying on the torsional reset force of the coil spring 713, the rotating rod 709 can be driven to rotate and disengage from the inner cavity of the first mounting seat 701, thereby completing the synchronous unlocking of each connection node, realizing the rapid separation of the long shell 506 and the U-shaped shell 501, and the rear box 301 and the three sets of front boxes 301, improving the disassembly efficiency of the device. After the device is disassembled, it can be quickly transferred to other construction heights or construction points of the steel column 1 for reassembly, improving the turnover rate and construction flexibility of the device.

[0066] During the process of the U-shaped shell 501 and the long shell 506 approaching each other and completing assembly, the U-shaped rod 601 and the long rod 604 can be automatically and synchronously connected. At the same time, the connection system 7 is triggered to automatically lock the U-shaped shell 501 and the long shell 506, thereby forming a full-angle limiting and locking structure on the steel column 1 with the three sets of boxes 301 and the remaining set of boxes 301. The above assembly and locking actions are all automatically completed during the process of the long shell 506 approaching the U-shaped shell 501, without the need for additional operation steps, simplifying the overall assembly process and effectively shortening the overall cycle of steel structure docking construction.

[0067] Main references Figure 1 , Figure 2 , Figure 4 , Figure 6 As shown, the three sets of boxes 301 and the U-shaped shell 501 that make up the U-shaped frame structure are fixedly connected by connecting pieces 8, thus enabling the three sets of boxes 301 and the bottom U-shaped shell 501 to form a semi-enclosed structure. The remaining set of boxes 301 is fixedly connected to the long shell 506 by connecting pieces 8, thus enabling the remaining set of boxes 301 and the long shell 506 to form a whole. After the above two parts are docked, the docking system 3 is docked, and the assembly system 5 is docked simultaneously, thereby achieving the effect of assembling and docking the entire equipment on the steel column 1.

[0068] Main references Figure 4 and Figure 5As shown, a first anti-slip plate 9 is installed on the side wall of the U-shaped shell 501 and the long shell 506 near the steel column 1, and a second anti-slip plate 10 is installed on the side wall of the box 301 near the steel column 1. Specifically, the materials of the first anti-slip plate 9 and the second anti-slip plate 10 are selected from one or more of rubber-based composite materials, high wear-resistant engineering plastics, and anti-slip alloy steel with serrated surfaces. The first anti-slip plate 9 and the second anti-slip plate 10 are made of materials with a high coefficient of friction, thereby increasing the static friction force of the contact surface between the device and the side wall of the steel column 1. This ensures that after the device is assembled onto the outer wall of the steel column 1, it can effectively resist the downward force generated by its own weight and construction load, avoiding the risk of relative downward slippage. Specifically, in this embodiment, the first anti-slip sheet 9 and the second anti-slip sheet 10 are made of rubber-based composite materials, such as nitrile rubber and neoprene rubber. Rubber-based composite materials possess excellent elastic deformation capabilities, allowing for microscopic adhesion when in contact with the sidewall of the steel column 1, increasing the actual contact area. Simultaneously, their coefficient of friction is significantly higher than that of ordinary metals, enhancing the static friction threshold of the contact surface. Alternatively, high-wear-resistant engineering plastics, such as ultra-high molecular weight polyethylene and polyoxymethylene, can be used. Ultra-high molecular weight polyethylene and other engineering plastics not only have stable coefficients of friction but also excellent wear resistance, ensuring that long-term contact will not lead to a decrease in anti-slip performance due to wear. Alternatively, anti-slip alloy steel with a serrated surface can be used. This serrated surface allows for microscopic interlocking with the sidewall of the steel column 1 through its serrated structure, converting sliding friction at the contact surface into a partial form of rolling friction resistance, thus enhancing the anti-slip effect through mechanical interlocking. The first anti-slip sheet 9 and the second anti-slip sheet 10 can be made of materials that meet the above requirements; further details and limitations are omitted here.

[0069] This invention utilizes the contact action of high-friction coefficient materials to effectively resist the downward force generated by the device's own weight and external construction forces through the close fit between the first anti-slip plate 9, the second anti-slip plate 10, and the side wall of the steel column 1, thus preventing the device from slipping during construction. Compared with traditional devices without anti-slip structures, this invention improves safety in high-altitude or high-load construction scenarios.

[0070] It is also worth noting that this device does not provide overall support for steel beam 2; it is only used to achieve the centering and alignment of steel beam 2 on the side wall of steel column 1 during construction. Support for steel beam 2 at steel column 1 can be achieved using existing hoisting equipment. After the existing hoisting equipment lifts steel beam 2 to the preset position on the side wall of steel column 1, this device can be used to achieve simultaneous centering and alignment of four sets of steel beams 2 around the side wall of steel column 1. The equipment used for hoisting steel beam 2 is within the scope of existing technology and only needs to meet the requirements of this device; its specific structure, model, and parameters will not be further limited or elaborated here.

[0071] In addition, the side wall of the steel column 1 can be equipped with 1 to 4 sets of steel beams 2 according to actual needs. The number of installations is not limited and it is applicable to a wide range of scenarios.

[0072] Compared to traditional steel structure docking devices, this invention eliminates the need for large auxiliary equipment and requires only a small amount of manpower to achieve high-precision synchronous alignment of the steel beams around the steel column. Furthermore, the device's assembly, disassembly, and transfer do not rely on the operating space at the top of the steel column, making it flexible and adaptable to complex construction scenarios such as high-altitude and confined spaces. In addition, the automatic locking and synchronous drive linkage design reduces the interference of human error on construction quality, achieving a dual optimization of construction efficiency and docking accuracy. This effectively overcomes the technical shortcomings of traditional construction methods, such as difficult positioning and low efficiency, providing a complete integrated solution for the efficient construction of steel structure projects such as large stadiums and factories.

[0073] This embodiment describes a steel structure construction docking device. The principle behind docking and positioning four sets of steel beams 2 around the side wall of the steel column 1 is as follows:

[0074] The overall assembly principle of the device is as follows: The U-shaped frame structure formed by the fixed connection of the three sets of docking systems 3 on the front side is attached to the front side wall and the left and right side walls of the steel column 1. At the same time, the inner side wall of the U-shaped shell 501 below the three sets of docking systems 3 is tightly attached to the front side wall and the left and right side walls of the steel column 1. Then, the remaining set of docking systems 3 on the rear side is moved towards the three sets of docking systems 3 on the front side, so that the sleeve 402 is fitted onto the outside of the insert block 401, thereby realizing the initial assembly of the rear box 301 with the three sets of boxes 301 on the front side.

[0075] The locking and fastening principle of the connection system 7: During the assembly process of the rear box 301 and the three sets of front boxes 301, the long shell 506 at the bottom of the rear box 301 is synchronously driven to move closer to the U-shaped shell 501. During this displacement process, the free end of the drive rod 711 gradually comes into contact with the roller 706. Under the limiting action of the roller 706, the drive rod 711 rotates around the pivot 708, and drives the pivot 708 and the rotating rod 709 to move towards the inner cavity of the first mounting base 701. During this process, the coil spring 713 undergoes torsional deformation with the rotation of the pivot 708. At the same time, the wedge surface 703 moves upward under the rotation drive of the rotating rod 709, forcing the spring 704 to undergo compression deformation. When the rotating rod 709 is fully rotated and embedded in the inner cavity of the first mounting base 701, the second insertion hole 710 and the insertion rod 702... To achieve precise alignment, under the elastic restoring force of the spring 704, the drive rod 702 moves downward and drives the wedge surface 703 to insert into the inner cavity of the second insertion hole 710. At this time, after the rotating rod 709 is fully embedded in the inner cavity of the first mounting base 701, it is subject to multiple limits from the upper and lower inner walls, the side inner walls of the first mounting base 701, and the side wall of the drive rod 702, thus achieving a stable connection of the rotating rod 709 at the first mounting base 701, thereby completing the stable assembly of the long shell 506 and the U-shaped shell 501. Finally, the assembly system 5 and the docking system 3 are reliably assembled on the steel column 1. At the same time, with the help of the first anti-slip plate 9 provided on the side wall of the U-shaped shell 501 and the long shell 506, and the second anti-slip plate 10 provided on the side wall of the box 301, the adhesion friction, connection tightness and structural stability of the device after it is sleeved on the steel column 1 can be further improved.

[0076] The linkage and adaptation of the assembly system 5 and the drive system 6: During the assembly process of the long shell 506 and the U-shaped shell 501, the two free ends of the U-shaped rod 601 are simultaneously inserted into the inner cavity of the first insertion hole 606 on the long rod 604. Based on this connection, the displacement of the U-shaped rod 601 in the inner cavity of the U-shaped shell 501 in the vertical direction can simultaneously drive the long rod 604 to move in the vertical direction along the inner cavity of the long shell 506.

[0077] Synchronous centering alignment principle: When each set of drive arms 309 moves downward, it drives the corresponding U-shaped frame 308 to move downward synchronously, driving the two sets of sliding pins 307 on both sides of the top of the U-shaped frame 308 to slide along the inner cavity of the through groove on the drive seat 306; because the through groove on the drive seat 306 has an inclined structure design, the sliding pins 307 during the downward process will drive the drive seat 306 and the moving block 304 to move synchronously in the middle direction of the guide rod 303, thereby driving the two sets of limit plates 30... 5. Moving towards each other, pushing both sides of steel beam 2 toward the centerline of the side wall of steel column 1 and completing centering and alignment; ultimately achieving synchronous docking and positioning of the four sets of steel beams 2 on the four sides of steel column 1, and each set of steel beams 2 after being limited by two sets of limiting plates 305 is in the center position of the corresponding side wall of steel column 1; at the same time, the four sets of steel beams 2 remain at the same height plane around steel column 1, completing the centering docking of the four sets of steel beams 2 at the same height on the four sides of steel column 1, providing a precise positioning reference for subsequent welding processes.

[0078] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
