[0002] With the continuous advancement of architectural technology, modern venues are increasingly demanding large-scale functional spaces. Traditional frame structures, limited by their form, often require numerous beam-column support systems to achieve large spans. This fragments the interior space and makes it difficult to meet the requirements for flexible and expansive spatial use. Therefore, large-span venues are currently adopting new structural systems such as long-span space trusses or large lattice trusses to achieve more efficient structural performance and space utilization.

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] like Figures 1 to 9 This embodiment provides a large-scale grid truss segmented assembly and hoisting device. The construction of large grid truss venues often involves the installation of L-shaped components up to tens of meters in length. Traditional construction methods typically rely on setting up complex temporary support systems and hoisting them segment by segment. This not only results in a long construction period, high labor and material investment, but also low construction efficiency. However, the use of this device allows for simultaneous hoisting and assembly of components on-site, significantly reducing reliance on temporary support structures.

[0033] In some specific embodiments, the large grid truss segment assembly and hoisting equipment includes a main crane 1 and a traction trolley 11 detachably pivotally connected to one side of the main crane 1;

[0034] The control box 8 is installed on one side of the top of the traction trolley 11;

[0035] The support sleeve 2 is rotatably mounted on the vehicle plate of the traction trolley 11, and a hydraulic cylinder 21 is installed in the support sleeve 2, the hydraulic cylinder 21 is electrically connected to the control box 8, and the telescopic end of the hydraulic cylinder 21 is rotatably mounted on the turning frame 3, one end of the turning frame 3 is fixedly mounted with a clamping mechanism 1 4, and the other end of the turning frame 3 is mounted with a clamping mechanism 2 5 docking with the clamping mechanism 1 4, the clamping mechanism 2 5 includes a support shaft 51, the support shaft 51 is rotatably mounted on the side plate at one end of the turning frame 3, and a platform 2 52 is fixed on the support shaft 51, and a side clamping assembly 53 is symmetrically installed on one side of the platform 2 52, and a rotating cylinder 54 for driving the support shaft 51 to rotate is installed on the turning frame 3, and the rotating cylinder 54 is electrically connected to the control box 8;

[0036] A vibration mechanism 6, used for striking and testing after docking and installation, the vibration mechanism 6 is installed on one side of the second stand 52;

[0037] The rotary motor 7 is used to drive the turning frame 3 to adjust the support angle. The rotary motor 7 is fixedly installed on the top of the hydraulic cylinder 21 , and the rotary motor 7 is electrically connected to the control box 8 .

[0038] In some specific embodiments, during the segmented assembly of grid truss components, when horizontal docking is required, one end of the component to be docked is first clamped and secured using a clamping mechanism 1 (4). Subsequently, the end of the other component to be docked is clamped using a clamping mechanism 2 (5). After clamping is complete, the docking assembly operation is performed. If there is an angular deviation in the assembly joint, the rotary cylinder 54 is activated to drive the support shaft 51 to rotate on the tilting frame 3, thereby causing the clamping mechanism 2 (5) to adjust its angle relative to the clamping mechanism 1 (4) to achieve precise angular alignment. After docking is completed, the vibration mechanism 6 is activated to apply a vibration load to the connection to simulate the structural stress state and test the connection stability and installation quality. After confirming that the connection is secure and meets the lifting conditions, the main crane 1 is used for the overall lifting operation. During the lifting process, the rotary motor 7 can be controlled to drive the tilting frame 3 to adjust the spatial posture of the truss assembly, facilitating precise on-site positioning and high-altitude docking installation, thereby improving assembly efficiency and construction safety.

[0039] In some specific embodiments, such as Figures 1 to 9 A worm gear 22 is fixedly mounted on the bottom end of the support sleeve 2. A worm 23 is rotatably mounted on the bottom of the vehicle deck of the traction trolley 11, and the worm 23 engages with the worm gear 22. Furthermore, a servo motor 24 is fixedly mounted on the bottom of the vehicle deck of the traction trolley 11 for driving the worm 23 to rotate. The servo motor 24 is electrically connected to the control box 8 to achieve automatic control of the transmission system.

[0040] In some possible implementations, during the lifting process, in order to achieve directional adjustment of the overall posture, the servo motor 24 can be used to drive the worm 23 to rotate, and the meshing transmission relationship between the worm 23 and the worm wheel 22 can be used to drive the support sleeve 2 to rotate, thereby synchronously driving the hydraulic cylinder 21 and the turning frame 3 to rotate, thereby achieving precise adjustment of the spatial orientation of the lifting components, and facilitating directional positioning according to on-site installation requirements.

[0041] In some specific embodiments, the clamping mechanism 1 includes two sets of guide rods 41, each of which is mounted on the top horizontal plate of the flip frame 3. A sliding plate 42 is slidably connected to both sets of guide rods 41. A platform 1 43 is fixedly mounted on the sliding plate 42, and the platform 1 43 is configured to dock with the platform 2 52. A hydraulic rod 1 44 is symmetrically mounted on one side of the platform 1 43, and a pressure plate 1 45 is fixedly connected to the telescopic end of the hydraulic rod 1 44. A lead screw 46 is rotatably mounted on the flip frame 3, and a drive motor 47 is fixedly mounted thereto for driving the lead screw 46. The drive motor 47 is electrically connected to the control box 8 to achieve precise adjustment and automatic control of the position of the sliding plate 42.

[0042] In some specific embodiments, the side clamp assembly 53 includes two hydraulic rods 531 arranged in two sets, symmetrically mounted on one side of the second platform 52. The telescopic ends of the two sets of hydraulic rods 531 are commonly connected to and fixed to a side clamping plate 532. A limiting frame 533 is fixedly mounted on the side clamping plate 532. The vertical plate portion of the limiting frame 533 is fixedly connected to a third hydraulic rod 534. The telescopic end of the third hydraulic rod 534 is mounted to a first limiting roller 535. Simultaneously, a fourth hydraulic rod 536 is mounted on the horizontal plate portion of the limiting frame 533. The telescopic end of the fourth hydraulic rod 536 is connected to a second limiting roller 537, which is used to achieve multi-directional limiting and auxiliary positioning of the clamped workpiece, thereby improving clamping accuracy and stability.

[0043] In some possible embodiments, during the assembly process, component one is first placed on platform one 43, with the mating end facing toward the side clamp assembly 53. Hydraulic rod one 44 is then activated, driving pressure plate one 45 to firmly press component one against the surface of platform one 43. Component two is then placed on platform two 52, with the mating portion aligned with component one. Hydraulic rod two 531 is then activated, driving side clamping plates 532 to secure component two. Drive motor 47 is then activated, and the rotation of lead screw 46 drives slide plate 42 along guide rod 41, thereby pushing platform one 43 toward platform two 52, achieving precise docking of component one with component two. After docking, structural connection is achieved using welding or bolting, depending on design requirements. After assembly is complete, if lifting operations are required, hydraulic rod 1 44 is first retracted to release the clamping force on component 1. Hydraulic rod 3 534 is then activated, driving limit roller 1 535 to contact and apply pressure to the surface of component 2. Hydraulic rod 4 536 is then activated, causing limit roller 2 537 to contact and act on the other side of component 2, forming a bidirectional limit constraint. Hydraulic rod 2 531 is then retracted to release the side clamp 532, releasing component 2. At this point, the component is in a semi-constrained state and can be hoisted as a whole using the main crane 1. During the hoisting process, limit rollers 1 535 and 2 537 dynamically constrain the component, effectively suppressing sway and deviation during the hoisting process and ensuring safe hoisting and accurate installation.

[0044] In some specific embodiments, the bottom end of the platform 1 43 is symmetrically provided with T-shaped bosses 431, and the side panels of the flip frame 3 are provided with T-shaped slots 301 that match the T-shaped bosses 431. When the platform 1 43 slides along the guide direction, the sliding fit between the T-shaped bosses 431 and the T-shaped slots 301 not only improves the movement stability of the platform 1 43, but also further enhances its overall load-bearing capacity and structural support strength.

[0045] In some specific embodiments, the vibration mechanism 6 includes an adapter frame 61, which is fixedly arranged on the other side of the second platform 52, and a limiting sleeve 62 is fixedly installed on the adapter frame 61. A vibration rod 63 is slidably connected to the interior of the limiting sleeve 62, and the end of the vibration rod 63 is fixedly connected to a driving plate 64, and a limiting slot 601 is defined on the driving plate 64.

[0046] A power motor 65 is fixedly mounted on the adapter frame 61. The power motor 65 is electrically connected to the control box 8. The output shaft thereof is fixedly connected to a drive disk 66. A transmission rod 67 is provided on the top edge of the drive disk 66. The end of the transmission rod 67 away from the drive disk 66 is inserted into the limiting groove 601, and the diameter of the transmission rod 67 is adapted to the groove width of the limiting groove 601 to achieve stable transmission of reciprocating motion.

[0047] The vibration rod 63 is composed of a fixed rod 631, which is fixedly connected to the drive plate 64 and forms a sliding fit with the limiting sleeve 62. A movable rod 632 is movably inserted at the end of the fixed rod 631 away from the drive plate 64. A rubber ball 633 is fixedly connected to the front end of the movable rod 632 to achieve flexible contact vibration. A return spring 634 is mounted on the movable rod 632. One end of the return spring 634 is connected to the fixed rod 631 and the other end is connected to the movable rod 632 to achieve automatic reset after vibration.

[0048] Furthermore, limiting rods 641 are symmetrically arranged on both sides of the driving plate 64. The end of the limiting rod 641 away from the driving plate 64 passes through the through hole opened on the limiting sleeve 62 to form a guiding and auxiliary limiting structure to enhance the movement stability and direction control accuracy during the vibration process.

[0049] In some possible embodiments, when the vibration mechanism 6 is in use, when the components are completed and the connection strength test is required, the power motor 65 is started to drive the drive disk 66 to rotate, driving the transmission rod 67 to rotate synchronously. While rotating, the transmission rod 67 slides in the limiting groove 601, thereby pushing the drive plate 64 to reciprocate. The drive plate 64 drives the fixed rod 631 to perform reciprocating linear motion along the axial direction of the limiting sleeve 62. In the process of the fixed rod 631 moving back and forth, the motion is transmitted to the movable rod 632 through the action of the reset spring 634, so that the movable rod 632 drives the rubber ball 633 to move back and forth synchronously, and applies a periodic impact force to the connection part of the component that has been docked. By setting the vibration frequency and duration, the stress state under actual working conditions is simulated to detect the connection reliability and installation stability of the splicing parts, thereby effectively evaluating the docking quality and ensuring that the structural connection is firm, safe and reliable.

[0050] In some possible implementations, the stroke of the reciprocating movement is greater than the minimum distance between the rubber ball 633 and the docking component, thereby generating an effective impact on the component during the movement.

[0051] In some specific embodiments, the tractor 11 is further equipped with a steering member 12 for independently supporting the tractor body and enabling movement and steering. The steering member 12 consists of a steering shaft, a handwheel, and a steering wheel. The steering shaft is rotatably mounted to the front end of the tractor 11, with the top end of the steering shaft connected to the handwheel and the bottom end mounted with the steering wheel. After the tractor 11 is separated from the main crane 1, the handwheel can be manually operated to rotate the steering shaft, which in turn drives the steering wheel to deflect, enabling free pushing and flexible steering of the tractor 11, facilitating convenient transportation and position adjustment at the construction site.

[0052] In some possible implementations, the trolley 11 may be equipped with a power mechanism that enables autonomous driving and movement. The control box 8 also supports communication with a remote operator, enabling remote control of the equipment. During lifting operations, the operator can use remote control to distance themselves from the area below the boom of the main crane 1, complying with safety regulations for lifting operations and effectively improving overall safety and controllability.

[0053] In some specific embodiments, the working principle of the large grid truss segment assembly and hoisting equipment is as follows:

[0054] During the segmented assembly of grid truss components, for horizontal docking, one end of the component to be docked is first clamped and secured using clamping mechanism 1 (4). Subsequently, clamping mechanism 2 (5) clamps the end of the other component to be docked. If there is angular deviation, the control system activates rotary cylinder 54, rotating support shaft 51 on tilting frame 3. This adjusts the spatial angle of clamping mechanism 2 (5) relative to clamping mechanism 1 (4) to achieve precise docking positioning.

[0055] During the hoisting process, the rotary motor 7 drives the tilting frame 3 to rotate, adjusting the overall installation posture and facilitating high-altitude docking operations. To further meet the needs of azimuth adjustment, the servo motor 24 can also be activated to drive the rotation of the worm 23. Through its meshing transmission relationship with the worm gear 22, it drives the rotation of the support sleeve 2, which in turn synchronously drives the hydraulic cylinder 21 and the tilting frame 3 to rotate as a whole, achieving flexible adjustment of the hoisting direction to adapt to different installation orientation requirements.

[0056] In the specific docking and assembly operation, first place component one on the platform one 43, and make the docking part face the side clamp assembly 53, then start the hydraulic rod one 44, drive the pressure plate one 45 to move, and firmly press component one against the surface of the platform one 43; then place component two on the platform two 52, and make its docking part face component one, then start the hydraulic rod two 531, drive the side clamping plate 532 to clamp component two.

[0057] The drive motor 47 is then activated, and the rotation of the lead screw 46 drives the sliding plate 42 to move along the guide rod 41, thereby pushing the first platform 43 toward the second platform 52, so that the two components can be accurately docked. After the docking is completed, the structural connection is completed by welding or bolting according to the design requirements.

[0058] After the assembly is completed, if lifting operation is required, first control the hydraulic rod 1 44 to retract and reset to release the clamping state of component 1; then start the hydraulic rod 3 534 to drive the limit roller 1 535 to contact and apply pressure to the surface of component 2, and then control the hydraulic rod 4 536 to move, so that the limit roller 2 537 contacts and acts on the other side of component 2, forming a two-way limit constraint; then control the hydraulic rod 2 531 to retract and reset, driving the side clamp 532 to release component 2.

[0059] At this time, the component is in a semi-constrained state and can be hoisted as a whole by the main crane 1. During the hoisting process, the component is dynamically limited by the limit roller 1 535 and the limit roller 2 537, which effectively suppresses the shaking and deviation during the hoisting process and ensures the safety of hoisting and the accuracy of installation.

[0060] To verify the connection stability of the docking joint, after the components are docked and installed, the power motor 65 can be started to rotate the drive disc 66. The drive disc 66 slides within the limit slot 601 via the transmission rod 67, pushing the drive plate 64 to reciprocate, thereby driving the fixed rod 631 to move back and forth along the direction of the limit sleeve 62. This movement is transmitted to the movable rod 632 via the return spring 634, causing the rubber ball 633 to reciprocate synchronously with the movable rod 632, applying periodic impact force to the docked component connection. By setting the vibration frequency and duration, the stress state under actual working conditions is simulated to test the connection reliability and installation stability of the splicing parts, thereby effectively evaluating the docking quality and ensuring a firm, safe and reliable structural connection.
