[0002] With the continuous progress of building technology, the demand for the use function of large spaces in modern venue buildings is increasing day by day. Due to the limitations of its own form, the traditional frame structure usually requires a large number of beam-column support systems to achieve large-span spaces, resulting in the division of the indoor space and making it difficult to meet the requirements of flexible and open space use. Therefore, at present, large-span venues mostly adopt new structural systems such as large-span space trusses or large grid trusses to achieve more efficient structural performance and space utilization.
[0003] In the actual construction process, the installation of such large-span truss structures usually relies on a complex temporary support system to ensure the stability and safety of the structure during the assembly and hoisting stages. However, the erection and demolition of these support systems not only consume a large amount of manpower and time but also significantly extend the overall construction period. In addition, considering the convenience of transportation and manufacturing, large grid trusses are usually constructed by means of segmented prefabrication, on-site assembly, and overall hoisting.

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0020] As Figures 1 to 9 , this embodiment provides a large-scale grid truss segmented assembly and hoisting device. During the construction of a large-scale grid truss venue, the installation of L-shaped components with a length of dozens of meters is often involved. Traditional construction methods usually rely on building a complex temporary support system and use the method of hoisting section by section for installation, which not only has a long construction period, large investment in manpower and material resources, but also has low construction efficiency. By using this device, the on-site hoisting and assembly operation of components can be realized, significantly reducing the dependence on the temporary support structure.
[0021] In some specific embodiments, the large-scale grid truss segmented assembly and hoisting device includes a main crane 1 and a towing trolley 11 detachably pivotally connected to one side of the main crane 1; A control box 8 is installed on one side of the top of the towing trolley 11; A support sleeve 2 is rotatably installed on the carriage plate of the towing 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 a telescopic end of the hydraulic cylinder 21 is rotatably installed with a turning frame 3. A clamping mechanism one 4 is fixedly installed at one end of the turning frame 3, and a clamping mechanism two 5 for docking and cooperating with the clamping mechanism one 4 is installed at the other end of the turning frame 3. The clamping mechanism two 5 includes a support shaft 51 rotatably installed on a side plate at one end of the turning frame 3, and a fixed bench two 52 is arranged on the support shaft 51. Side clamping assemblies 53 are symmetrically installed on one side of the bench two 52. A rotary cylinder 54 for driving the support shaft 51 to rotate is installed on the turning frame 3, and the rotary cylinder 54 is electrically connected to the control box 8; A shock mechanism 6 for impact detection after docking and installation is installed on one side of the bench two 52; A rotary motor 7 for driving the turning frame 3 to adjust the support angle is fixedly installed at the top of the hydraulic cylinder 21, and the rotary motor 7 is electrically connected to the control box 8.
[0022] In some specific embodiments, during the segmented assembly operation of the grid truss components, when horizontal docking is required, first, one end of the component to be docked is clamped and fixed by the first clamping mechanism 4. Subsequently, the end of the other component to be docked is clamped by the second clamping mechanism 5. After clamping, the docking and assembly operation is carried out. When there is an angular deviation in the assembly joint, the rotary cylinder 54 is started to drive the support shaft 51 to rotate on the turnover frame 3, thereby driving the second clamping mechanism 5 to adjust the angle relative to the first clamping mechanism 4 to achieve precise angular alignment. After docking, the shock mechanism 6 is enabled to apply a vibration load to the connection part to simulate the structural stress state and detect the joint stability and installation quality of the connection part. After confirming that the connection is firm and meets the hoisting conditions, the main crane 1 is used for the overall hoisting operation. During the hoisting process, the spatial attitude of the truss assembly can be adjusted by controlling the rotary motor 7 to drive the turnover frame 3 to facilitate accurate on-site positioning and high-altitude docking installation, thereby improving the assembly efficiency and construction safety.
[0023] In some specific embodiments, such as Figures 1 to 9 , a worm gear 22 is fixedly sleeved at the bottom end of the support sleeve 2, and a worm 23 is rotatably installed at the bottom of the car body of the towing cart 11. The worm 23 meshes with the worm gear 22. At the same time, a servo motor 24 for driving the worm 23 to rotate is fixedly installed at the bottom of the car body of the towing cart 11, and the servo motor 24 is electrically connected to the control box 8 to realize the automatic control of the transmission system.
[0024] In some possible embodiments, during the hoisting process, to realize the direction adjustment of the overall attitude, the servo motor 24 can be used to drive the worm 23 to rotate. By using the meshing transmission relationship between the worm 23 and the worm gear 22, the support sleeve 2 is driven to rotate, thereby synchronously driving the hydraulic cylinder 21 and the turnover frame 3 to rotate, realizing the precise adjustment of the spatial orientation of the hoisted component and facilitating the directional positioning according to the on-site installation requirements.
[0025] In some specific embodiments, the first clamping mechanism 4 includes a guide rod 41. There are two groups of the guide rods 41. The two groups of guide rods 41 are installed on the top cross plate of the turnover frame 3, and a sliding plate 42 is slidably connected to the two groups of guide rods 41. A bench 43 is fixedly installed on the sliding plate 42. The bench 43 is used for docking and matching with the bench 52. Hydraulic rods 44 are symmetrically arranged on one side of the bench 43, and a pressing plate 45 is fixedly connected to the telescopic end of the hydraulic rod 44. A lead screw 46 is rotatably installed on the turnover frame 3, and a driving motor 47 for driving the lead screw 46 to rotate is fixedly arranged. The driving motor 47 is electrically connected to the control box 8 to realize the precise adjustment and automatic control of the position of the sliding plate 42.
[0026] In some specific embodiments, the side clamping assembly 53 includes two hydraulic rods 531. The two hydraulic rods 531 are symmetrically installed on one side of the second platform 52, and the telescopic ends of the two hydraulic rods 531 are jointly connected and fixed with a side clamping plate 532. A limiting frame 533 is fixedly installed on the side clamping plate 532. A vertical plate portion of the limiting frame 533 is fixedly connected with a third hydraulic rod 534, and a first limiting roller 535 is installed at the telescopic end of the third hydraulic rod 534. At the same time, a fourth hydraulic rod 536 is arranged on a horizontal plate portion of the limiting frame 533, and a second limiting roller 537 is connected to the telescopic end of the fourth hydraulic rod 536, which is used to realize the multi-directional limiting and auxiliary positioning functions of the workpiece to be clamped, thereby improving the clamping accuracy and stability.
[0027] In some possible embodiments, during the assembly process, first place the first component on the first platform 43 with the butt end face facing the side clamping assembly 53. Then start the first hydraulic rod 44 to drive the first pressing plate 45 to act, and firmly press the first component against the surface of the first platform 43. Next, place the second component on the second platform 52 and align its docking part with the first component. Then start the second hydraulic rod 531 to drive the side clamping plate 532 to act and clamp and fix the second component. Then start the driving motor 47, and drive the sliding plate 42 to move along the direction of the guide rod 41 through the rotation of the lead screw 46, so as to push the first platform 43 towards the second platform 52, enabling the first component and the second component to achieve precise docking. After the docking is completed, perform structural connection by means of welding or bolt connection according to the design requirements. After the assembly is completed, if a lifting operation is required, first control the first hydraulic rod 44 to retract and reset to release the clamping state of the first component; then start the third hydraulic rod 534 to drive the first limiting roller 535 to contact and press against the surface of the second component, and then control the fourth hydraulic rod 536 to act so that the second limiting roller 537 contacts and acts on the other side of the second component to form a two-way limiting constraint; then control the second hydraulic rod 531 to retract and reset to drive the side clamping plate 532 to release the second component. At this time, the component is in a semi-constrained state, and the overall lifting operation can be implemented by the main crane 1. During the lifting process, the first limiting roller 535 and the second limiting roller 537 are used to perform dynamic limiting on the component, effectively suppressing the shaking and offset during the lifting process, and ensuring the safety of the lifting and the installation accuracy.
[0028] In some specific embodiments, T-shaped bosses 431 are symmetrically arranged at the bottom end of the first platform 43, and T-shaped grooves 301 matching the T-shaped bosses 431 are formed on the side plates of the flipping frame 3. When the first platform 43 slides along the guiding direction, through the sliding fit between the T-shaped bosses 431 and the T-shaped grooves 301, while improving the movement stability of the first platform 43, the overall load-bearing capacity and structural support strength are further enhanced.
[0029] In some specific embodiments, the shock mechanism 6 includes a transfer frame 61 which is fixedly arranged on the other side of the second bench 52, and a limiting sleeve 62 is fixedly installed on the transfer frame 61. A shock rod 63 is slidably connected inside the limiting sleeve 62. The end of the shock rod 63 is fixedly connected with a driving plate 64, and a limiting groove 601 is formed in the driving plate 64.
[0030] A power motor 65 is fixedly installed on the transfer frame 61. The power motor 65 is electrically connected with the control box 8, and its output shaft is fixedly connected with a driving disk 66. A transmission rod 67 is arranged at the top edge of the driving disk 66. The end of the transmission rod 67 away from the driving 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.
[0031] The shock rod 63 is composed of a fixed rod 631 which is fixedly connected with the driving plate 64 and forms a sliding fit relationship with the limiting sleeve 62. A movable rod 632 is movably inserted at the end of the fixed rod 631 away from the driving plate 64. A rubber sphere 633 is fixedly connected to the front end of the movable rod 632 for achieving flexible contact shock; a return spring 634 is sleeved on the movable rod 632. One end of the return spring 634 is connected with the fixed rod 631, and the other end is connected with the movable rod 632 for achieving automatic reset after shock.
[0032] Further, limiting rods 641 are symmetrically arranged on both sides of the driving plate 64. The ends of the limiting rods 641 away from the driving plate 64 pass through through holes formed in the limiting sleeve 62 to form a guiding and auxiliary limiting structure, so as to enhance the motion stability and direction control accuracy during the shock process.
[0033] In some possible embodiments, when the shock mechanism 6 is in use, when the components are completed with butt joint installation and connection strength detection is required, the power motor 65 is started to drive the driving 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 driving plate 64 to move reciprocally. The driving plate 64 drives the fixed rod 631 to make reciprocating linear motion along the axis direction of the limiting sleeve 62. During the forward and backward movement of the fixed rod 631, the movement is transmitted to the movable rod 632 through the action of the return spring 634, so that the movable rod 632 drives the rubber sphere 633 to move reciprocally synchronously, and a periodic impact force is applied to the connection part of the components that have completed butt joint. By setting the shock frequency and duration, the stress state under actual working conditions is simulated to detect the connection reliability and installation stability of the splicing part, so as to effectively evaluate the butt joint quality and ensure the firm, safe and reliable structural connection.
[0034] In some possible embodiments, the reciprocating movement stroke is greater than the minimum distance between the rubber sphere 633 and the docking component, so as to form an effective impact on the component during the movement.
[0035] In some specific embodiments, the towing cart 11 is further configured with a steering member 12 for independently supporting the vehicle body and realizing mobile steering. The steering member 12 is composed of a steering shaft, a handwheel and a steering wheel. The steering shaft is rotatably installed at the front end of the towing cart 11. The top end of the steering shaft is connected to the handwheel, and the bottom end is installed with the steering wheel. After the towing cart 11 is separated from the main crane 1, the handwheel can be manually controlled to drive the rotation of the steering shaft, and then drive the deflection of the steering wheel, so as to realize the free pushing and flexible steering of the towing cart 11, which is convenient for convenient transportation and position adjustment at the construction site.
[0036] In some possible embodiments, the towing cart 11 can be configured with a power mechanism, and the towing cart 11 can be autonomously driven and moved through the power mechanism. The control box 8 also supports the communication connection with the remote controller, so as to realize the remote control of the equipment. During the hoisting operation, the operator can remotely control away from the area under the suspension arm of the main crane 1, which conforms to the safety operation specifications of the hoisting operation and effectively improves the safety and controllability of the overall operation.
[0037] In some specific embodiments, the working principle of the large-scale grid truss segmented assembly and hoisting equipment is as follows: When carrying out the segmented assembly operation of the grid truss components, if it is a horizontal docking form, first clamp and fix one end of the component to be docked through the clamping mechanism one 4, and then use the clamping mechanism two 5 to clamp the end of the other component to be docked. In the case of an angular deviation, the control system drives the rotary cylinder 54 to act, drives the support shaft 51 to rotate on the turnover frame 3, so as to adjust the spatial angle of the clamping mechanism two 5 relative to the clamping mechanism one 4, and realize accurate docking positioning.
[0038] During the hoisting process, the turnover frame 3 is driven to rotate by the rotary motor 7 to adjust the overall installation posture, which is convenient for high-altitude docking operation. To further meet the azimuth adjustment requirements, the servo motor 24 can also be started to drive the rotation of the worm 23, and through its meshing transmission relationship with the worm gear 22, drive the support sleeve 2 to rotate, and then synchronously drive the hydraulic cylinder 21 and the turnover frame 3 to rotate as a whole, so as to realize the flexible adjustment of the hoisting direction and make it adapt to the requirements of different installation azimuths.
[0039] In the specific docking and assembling operation, first place Component 1 on Bench 1 43, with the docking part facing the side clamping assembly 53. Then start Hydraulic Rod 1 44 to drive Press Plate 1 45 to act, firmly pressing Component 1 onto the surface of Bench 1 43. Next, place Component 2 on Bench 2 52, with its docking part directly facing Component 1. Then start Hydraulic Rod 2 531 to drive Side Clamping Plate 532 to act, clamping and fixing Component 2.
[0040] Subsequently, start Drive Motor 47. The rotation of Lead Screw 46 drives Slide Plate 42 to move along the direction of Guide Rod 41, thereby pushing Bench 1 43 towards Bench 2 52, enabling the two components to achieve precise docking. After docking is completed, perform structural connection by means such as welding or bolt connection according to the design requirements.
[0041] After assembly, if lifting operation is required, first control Hydraulic Rod 1 44 to retract and reset, releasing the clamping state of Component 1. Then start Hydraulic Rod 3 534 to drive Limit Roller 1 535 to contact and press on the surface of Component 2. Next, control Hydraulic Rod 4 536 to act, so that Limit Roller 2 537 contacts and acts on the other side of Component 2, forming a two-way limit constraint. Then control Hydraulic Rod 2 531 to retract and reset, driving Side Clamping Plate 532 to release Component 2.
[0042] At this time, the component is in a semi-constrained state, and the overall lifting operation can be carried out by Main Crane 1. During the lifting process, rely on Limit Roller 1 535 and Limit Roller 2 537 to perform dynamic limit on the component, effectively suppressing the shaking and offset during the lifting process, ensuring the safety of lifting and the installation accuracy.
[0043] To verify the connection stability of the docking part, after the components are docked and installed, Power Motor 65 can be started to drive Drive Disc 66 to rotate. Drive Disc 66 slides in Limit Slot 601 through Transmission Rod 67, pushing Drive Plate 64 to reciprocate, thereby driving Fixed Rod 631 to move back and forth along the direction of Limit Sleeve 62. The movement is transmitted to Movable Rod 632 through Return Spring 634, so that Rubber Sphere 633 reciprocates synchronously with Movable Rod 632, applying periodic impact force to the connection part of the docked components. By setting the vibration frequency and duration, simulate the stress state under actual working conditions to detect the connection reliability and installation stability of the splicing part, thereby effectively evaluating the docking quality and ensuring the firmness, safety and reliability of the structural connection.
