Description

Technical Field

[0001] This invention relates to the field of steel structure construction technology, and more specifically, to a steel-wood hybrid structure integral suspension lifting and conveying equipment. Background Technology

[0002] In the construction of large-span spatial buildings such as large stadiums, the installation of steel-wood main trusses or large steel structure roofs generally adopts a multi-point overall lifting process. This process usually involves setting up multiple sets of temporary lifting supports on the construction site and deploying lifting equipment such as hydraulic jacks along the line to achieve the high-altitude lifting of large-tonnage components.

[0003] However, existing lifting supports often only have vertical suspension and lifting functions, and their overall structure is a fixed, single, rigid load-bearing system. In actual construction operations, due to inherent manufacturing errors and deformations in the processing and assembly of building components, or due to synchronous deviations between lifting points during multi-point coordinated lifting, it is often necessary to fine-tune the initial suspension position of the lifting equipment or the horizontal axis during the lifting process. Because existing lifting supports have a single function, the position of the lifting point at the top cannot be moved after welding and fixing, making it difficult to flexibly adjust the lateral and axial deviations of the lifting point position. When facing multi-point linkage conditions, this single-point unadjustability can easily lead to difficulties in aligning the positions of multiple sets of equipment, thereby causing additional stress or even eccentric loads on the truss structure. This not only reduces the construction efficiency of high-altitude assembly but also adversely affects the structural safety of the entire lifting project. Therefore, it is urgent to design a steel-wood hybrid structure overall suspension lifting and conveying equipment to solve the above problems. Summary of the Invention

[0004] The present invention aims to solve the problems of existing lifting supports having limited functions and difficulty in flexibly adjusting the lifting position.

[0005] To address the aforementioned problems, this invention provides a steel-wood hybrid structure integral suspension lifting and conveying device, comprising a column body composed of four upright columns. Horizontal connecting beams, evenly spaced, are fixedly installed between adjacent upright columns. Symmetrically distributed cantilever beams are fixedly installed at the top of the column body. Connecting plates, evenly spaced, are fixedly installed between adjacent cantilever beams. A sliding groove is formed on the upper surface of each cantilever beam, and a sliding plate is slidably installed in the groove. A through-type jack is fixedly installed in the sliding plate. The device further includes: a push-pull mechanism disposed between the cantilever beams for moving the sliding plate within the groove; and a moving mechanism disposed outside the sliding plate for assisting the movement of the sliding plate and ensuring its stability when lifting heavy objects.

[0006] The present invention provides a steel-wood hybrid structure integral suspension lifting and conveying equipment, which, compared with the prior art, has the following beneficial effects, but is not limited to: To address the limitations of existing lifting supports in terms of limited functionality and inflexible adjustment of lifting positions, this device includes a column structure composed of four uprights, which serve as the primary vertical load-bearing support on the construction site. Equally spaced horizontal connecting beams are fixed between adjacent uprights, significantly enhancing the spatial rigidity and lateral pressure resistance of the entire column structure. Symmetrically distributed cantilever beams are fixedly installed at the top of the column, extending inwards towards the venue. Equally spaced connecting plates are fixed between adjacent cantilever beams to further reinforce the cantilever sections and prevent outward tilting. The upper surface of each cantilever beam has a groove serving as a guide rail for equipment movement, with a sliding plate slidably installed within the groove. A through-type jack is fixedly installed within the sliding plate to bear the main lifting load, facilitating the overall upward lifting of the steel-wood main truss. The device also includes a push-pull mechanism positioned between the cantilever beams. This structure provides horizontal traction, thereby moving the slide plate along the cantilever beam in the chute, enabling horizontal axis adjustment of the through-hole jack. A moving mechanism located on the outside of the slide plate reduces friction and assists in slide plate movement during fine-tuning of the horizontal axis. When the vertically lifted load is subjected to extreme downward pressure, an elastic buffering mechanism ensures a tight, rigid fit between the slide plate and the bottom of the chute. This structure, with its rigid column structure composed of columns and cantilever beams, provides a reliable load-bearing foundation for heavy-duty lifting. Combined with the slide plate and jack, this equipment not only performs vertical overall suspension lifting but also allows for flexible adjustment of the initial suspension position as needed. This effectively solves the technical problems of traditional lifting supports having limited functionality and difficulty in controlling and fine-tuning multi-point linkage positions, greatly improving the efficiency and safety of on-site construction and installation, resulting in better performance.

[0007] Furthermore, the push-pull mechanism includes a hydraulic cylinder fixedly installed on the outer wall of one side of the connecting plate. The telescopic end of the hydraulic cylinder faces the slide plate, and the telescopic end of the hydraulic cylinder is connected to the side wall of the slide plate through a connecting component. This mechanism is used to drive the slide plate to move horizontally without restricting the degree of freedom of the slide plate to move up and down.

[0008] Furthermore, the connecting assembly includes a displacement plate and a limiting frame. The displacement plate is fixedly installed on the telescopic end of the hydraulic cylinder, and the limiting frame is fixedly installed on the side wall of the slide plate. A limiting groove is vertically formed in the limiting frame, and the displacement plate is movably installed in the limiting groove.

[0009] Furthermore, the moving mechanism is fixedly installed on the side plates on the left and right sides of the slide plate. A through hole is provided on the outer wall of the side plate, and a movable rod is movably installed in the through hole. A baffle is fixedly installed at the top of the movable rod, and a base plate is fixedly installed at the bottom of the movable rod. A roller is rotatably installed on the lower surface of the base plate, and the roller is in contact with the bottom inner wall of the slide groove. A spring is sleeved on the outer side of the movable rod. One end of the spring is connected to the lower surface of the baffle, and the other end of the spring is connected to the upper surface of the side plate.

[0010] Furthermore, the sidewall of the slide is provided with a movable groove, and side wheels are fixedly installed on the front and rear sides of the slide, and the side wheels are in contact with the inner wall of the movable groove.

[0011] Furthermore, a first diagonal brace is fixedly installed on one side of the outer wall of the column, and connecting beams with equal spacing are fixedly installed between adjacent first diagonal braces.

[0012] Furthermore, a second diagonal brace is fixedly installed on the lower surface of the cantilever beam, and the lower end of the second diagonal brace is fixedly connected to the side wall of the column.

[0013] Furthermore, the device comprises multiple sets of devices arranged in parallel along the same axis. Each set of devices further includes a coaxial alignment detection mechanism. The coaxial alignment detection mechanism includes an infrared emitter fixedly disposed on one side of the slide plate and an infrared receiver fixedly disposed on the other side of the slide plate. The infrared light axis emitted by the infrared emitter of any set of devices has a fixed relative positional relationship with the suspension center line of the through-hole jack of that set of devices. When the through-hole jacks of two adjacent sets of devices are kept on the same axis, the infrared light emitted by the infrared emitter of one set of devices can be received by the infrared receiver of the other set of devices.

[0014] Furthermore, it also includes a controller, which is electrically connected to the infrared receivers and the push-pull mechanism in the multiple sets of the equipment respectively. The controller is used to control the corresponding push-pull mechanism to drive the slide plate to move horizontally according to whether the infrared receiver receives the infrared light signal emitted by the infrared transmitter of the adjacent set of the equipment, until the infrared receivers of the multiple sets of the equipment all receive the corresponding infrared light signal, so as to realize the rapid positioning control of the through-hole jacks in the multiple sets of the equipment on the same axis.

[0015] Furthermore, a supporting bracket is fixedly connected to the bottom end of the column, and the column is made of H-beam steel, while the supporting bracket is a double-section H-beam steel structure. The column and the supporting bracket are butt-welded with a full penetration bevel. Attached Figure Description

[0025] See Figures 1-6 An embodiment of the present invention discloses a steel-wood hybrid structure integral suspension lifting and conveying device, comprising a column body composed of four columns 1. Horizontal connecting beams 11, evenly spaced, are fixedly arranged between adjacent columns 1. Symmetrically distributed cantilever beams 2 are fixedly installed at the top of the column body. Connecting plates 21, evenly spaced, are fixedly installed between adjacent cantilever beams 2. A groove 3 is formed on the upper surface of each cantilever beam 2, and a sliding plate 4 is slidably installed in the groove 3. A through-type jack 5 is fixedly installed in the sliding plate 4. The device also includes: a push-pull mechanism 6, disposed between the cantilever beams 2, for moving the sliding plate 4 within the groove 3; and a moving mechanism 7, disposed outside the sliding plate 4, for assisting the movement of the sliding plate 4 and ensuring its stability when lifting heavy objects.

[0026] In this embodiment, addressing the issues of limited functionality and difficulty in flexibly adjusting lifting positions in existing lifting supports, the device includes a column body composed of four upright columns 1, which serve as the primary vertical load-bearing support on the construction site. Equally spaced horizontal connecting beams 11 are fixedly installed between adjacent upright columns 1, significantly enhancing the spatial rigidity and lateral pressure resistance of the entire column structure. Symmetrically distributed cantilever beams 2 are fixedly installed at the top of the column body, extending inwards towards the venue. Equally spaced connecting plates 21 are fixedly installed between adjacent cantilever beams 2, further reinforcing the cantilever portion and preventing outward tilting. A groove 3 is formed on the upper surface of the cantilever beam 2, serving as a guide rail for equipment movement. A sliding plate 4 is slidably installed in the groove 3, and a through-type jack 5 is fixedly installed in the sliding plate 4 to bear the main lifting load, facilitating the overall upward lifting of the steel-wood main truss. The device also includes components disposed between the cantilever beams 2. The push-pull mechanism 6 provides horizontal traction, thereby driving the slide plate 4 to move along the cantilever beam 2 in the chute 3, realizing the horizontal axis adjustment of the through-hole jack 5. The moving mechanism 7, located on the outside of the slide plate 4, reduces friction and assists the movement of the slide plate 4 during fine-tuning of the horizontal axis. When the vertically lifted heavy object is subjected to a large downward pressure load, the elastic buffer conversion mechanism makes the slide plate 4 and the bottom of the chute 3 fit tightly and rigidly. This structure provides a reliable load-bearing foundation for large-tonnage lifting through the rigid column structure composed of the column 1 and the cantilever beam 2. At the same time, the combination of the slide plate 4 and the jack enables the equipment to not only complete the overall vertical suspension lifting operation, but also to flexibly adjust the initial suspension position as needed. This effectively solves the technical problems of traditional lifting supports having a single function and difficulty in controlling and fine-tuning the multi-point linkage position, greatly improving the efficiency and safety of on-site construction and installation, and achieving better results.

[0027] Optional, please refer to Figure 3 and Figure 4 The push-pull mechanism 6 includes a hydraulic cylinder 61 fixedly installed on the outer wall of one side of the connecting plate 21. The telescopic end of the hydraulic cylinder 61 faces the slide plate 4, and the telescopic end of the hydraulic cylinder 61 is connected to the side wall of the slide plate 4 through a connecting component. It is used to drive the slide plate 4 to move horizontally without restricting the degree of freedom of the slide plate 4 to move up and down.

[0028] In this embodiment, the push-pull mechanism 6 includes a hydraulic cylinder 61 fixedly installed on the outer wall of one side of the connecting plate 21. The hydraulic cylinder 61 can be a high-thrust double-acting hydraulic cylinder 61, and its inlet and outlet are connected to an external hydraulic pump station. The telescopic end of the hydraulic cylinder 61 is set towards the slide plate 4, and the telescopic end of the hydraulic cylinder 61 is connected to the side wall of the slide plate 4 through a connecting component. When it is necessary to adjust the horizontal position of the jack to align with the lifting point, the hydraulic system drives the telescopic end of the hydraulic cylinder 61 to extend or retract. The connecting component smoothly transmits this linear driving force to the slide plate 4, thereby driving the slide plate 4 to move horizontally within the slide groove 3. At the same time, the design of the connecting component does not restrict the vertical movement freedom of the slide plate 4. Allowing this vertical freedom can prevent the telescopic piston rod of the hydraulic cylinder 61 from being damaged by additional bending moment or shear force, effectively protecting the seals and internal structure of the hydraulic drive system. This push-pull design enables the large roof lifting system to have the ability to continuously and smoothly adjust and position itself, significantly reducing the stress fatigue risk of the heavy-duty transmission mechanism.

[0029] Optional, please refer to Figure 3 and Figure 4 The connecting assembly includes a displacement plate 62 and a limiting frame 63. The displacement plate 62 is fixedly installed on the telescopic end of the hydraulic cylinder 61, and the limiting frame 63 is fixedly installed on the side wall of the slide plate 4. A limiting groove 64 is vertically formed in the limiting frame 63, and the displacement plate 62 is movably installed in the limiting groove 64.

[0030] In this embodiment, to achieve horizontal force transmission and release vertical freedom, the specific structure of the connecting assembly includes a displacement plate 62 and a limiting frame 63. The displacement plate 62 is made of high-strength steel plate and is welded and fixedly installed at the telescopic end of the hydraulic cylinder 61, moving horizontally synchronously with the hydraulic piston rod. The limiting frame 63 is made of rectangular steel tube and fixedly installed on the side wall of the slide plate 4. A limiting groove 64 is vertically formed in the limiting frame 63, and the displacement plate 62 is movably installed in the limiting groove 64. During the operation of the hydraulic cylinder 61... When pushed or pulled horizontally, the vertical side of the displacement plate 62 abuts against the inner wall of the limiting groove 64, thereby transferring the horizontal pushing or pulling force to the slide plate 4 without damage, driving it to slide in the sliding groove 3. When the jack lifts a heavy object, causing the slide plate 4 to sink, the displacement plate 62 can slide freely up and down in the vertical direction in the limiting groove 64. There is no rigid compression between the two in the vertical direction, which effectively isolates the stress transmission of the push-pull cylinder to the large vertical load deformation, extends the service life of the equipment and reduces the risk of fatigue cracking of structural components under heavy load conditions.

[0031] Optional, please refer to Figure 3 , Figure 5 and Figure 6The moving mechanism 7 is fixedly installed on the side plates 71 on the left and right sides of the slide plate 4. The outer wall of the side plate 71 has a through hole, and a movable rod 73 is movably installed in the through hole. A baffle 72 is fixedly installed at the top of the movable rod 73, and a base plate 75 is fixedly installed at the bottom of the movable rod 73. A roller 76 is rotatably installed on the lower surface of the base plate 75, and the roller 76 is in contact with the bottom inner wall of the slide groove 3. A spring 74 is sleeved on the outer side of the movable rod 73. One end of the spring 74 is connected to the lower surface of the baffle 72, and the other end of the spring 74 is connected to the upper surface of the side plate 71.

[0032] In this embodiment, when the slide plate 4 moves horizontally along its axis without load, the preload of the spring 74 causes the slide plate 4 to be slightly lifted by the roller 76. The rolling friction of the roller 76 replaces the sliding friction between the slide plate 4 and the chute 3, greatly reducing the pushing and pulling resistance of the hydraulic cylinder 61 and achieving smooth conveying. When the through-hole jack 5 begins to lift a component with a huge tonnage, the huge downward load overcomes the elasticity of the spring 74, causing the spring 74 to compress. The bottom surface of the slide plate 4 falls directly onto the bottom surface of the chute 3, thus transforming into a large-area surface contact rigid bearing, ensuring absolute stability during heavy-load lifting, and effectively balancing the flexibility of movement and the safety of lifting.

[0033] Optional, please refer to Figure 3 , Figure 5 and Figure 6 The side wall of the slide 3 is also provided with a movable groove 82, and the front and rear sides of the slide plate 4 are fixedly installed with side wheels 81, and the side wheels 81 are in contact with the inner wall of the movable groove 82.

[0034] In this embodiment, to further improve the smoothness of the trajectory and anti-skewness capability of the slide plate 4 during movement, the side wall of the slide groove 3 is also provided with a movable groove 82 extending along its length. Side wheels 81 are fixedly installed on the front and rear sides of the slide plate 4, and the side wheels 81 are in contact with the inner wall of the movable groove 82. During the process of the hydraulic cylinder 61 pushing the slide plate 4 forward or backward, if there is a yaw tendency due to uneven force at multiple points or manufacturing and installation errors, the side wheels 81 will roll into contact with the side wall of the movable groove 82, rigidly restricting the lateral swing and torsion of the slide plate 4, so that it travels smoothly along the straight line of the slide groove 3. This guiding mechanism avoids hard scraping and jamming between the edge of the slide plate 4 and the inner wall of the slide groove 3, reduces wear and improves the working efficiency of the push-pull mechanism 6.

[0035] Optional, please refer to Figure 1 and Figure 2 A first diagonal brace 12 is fixedly installed on one side of the outer wall of the column 1, and connecting beams 13 with equal spacing are fixedly installed between adjacent first diagonal braces 12.

[0036] In this embodiment, regarding the main supporting structure of the equipment, a first diagonal brace 12 made of H-shaped steel is fixedly installed on one outer wall of the column 1 to strengthen the lateral stiffness of the entire column in the long side or the direction of weak stress. Equally spaced transverse connecting beams 13 are also fixedly installed between adjacent first diagonal braces 12. The first diagonal braces 12 and the connecting beams 13 together form a stable spatial truss shear-resistant system. When a large-tonnage through-hole jack 5 performs synchronous lifting operations on the steel-wood main truss at a height of tens of meters, wind load, inherent truss sway, and uneven lifting at multiple points will bring huge bending moments and horizontal shear forces to the supporting column. By adding the first diagonal brace 12 and connecting beams 13 to the side of the column 1, the lateral load borne by the column 1 can be effectively dispersed and transferred to adjacent frames or foundations, significantly reducing the slenderness ratio of a single column 1 and increasing the buckling instability critical load of the column 1, preventing frame deformation due to excessive local stress, and ensuring the structural safety of the entire suspended lifting equipment under extreme stress conditions.

[0037] Optional, please refer to Figure 1 and Figure 2 The lower surface of the cantilever beam 2 is fixedly equipped with a second diagonal brace 22, and the lower end of the second diagonal brace 22 is fixedly connected to the side wall of the column 1.

[0038] In this embodiment, to enhance the load-bearing capacity of the top suspension point, a second diagonal brace 22 made of high-strength steel is fixedly installed on the lower surface of the cantilever beam 2. The lower end of the second diagonal brace 22 is rigidly connected to the side wall of the column 1 by a full penetration bevel weld. When the cantilever beam 2 bears a vertical load of hundreds or even thousands of tons transmitted by the jack, its root will generate a large bending moment and shear force concentration. Traditional single-arm cantilever structures are prone to significant end deflection and sinking. However, after adding the second diagonal brace 22, the cantilever beam 2, the column 1 and the second diagonal brace 22 form a stable triangular geometric force model. The second diagonal brace 22 converts the vertical load at the end of the cantilever beam 2 into axial pressure and directly transmits it to the depth of the column 1, which greatly reduces the peak bending moment at the root of the cantilever beam 2 and effectively controls the vertical displacement of the cantilever end. This is crucial for the installation of steel-wood hybrid roofs that require high-precision synchronous lifting, and prevents the lifting equipment from jamming or the stress redistribution inside the truss due to the deformation of the support.

[0039] Optional, please refer to Figure 5The device consists of multiple sets of devices arranged in parallel along the same axis. Each set of devices further includes a coaxial alignment detection mechanism. The coaxial alignment detection mechanism includes an infrared emitter 91 fixedly disposed on one side of the slide plate 4 and an infrared receiver 92 fixedly disposed on the other side of the slide plate 4. The infrared light axis emitted by the infrared emitter 91 of any set of devices has a fixed relative positional relationship with the suspension center line of the through-hole jack 5 of that set of devices. When the through-hole jacks 5 of two adjacent sets of devices are kept on the same axis, the infrared light emitted by the infrared emitter 91 of one set of devices can be received by the infrared receiver 92 of the other set of devices.

[0040] In this embodiment, to address the complex construction requirement of simultaneously suspending and lifting the steel-wood main truss with 40 sets of lifting frames, and to ensure that the suspension positions of the 40 sets of lifting frames and the through-hole jacks 5 are strictly maintained on the same control axis, multiple sets of equipment are arranged in parallel along the same axis. Each set of equipment also includes a coaxial alignment detection mechanism. The coaxial alignment detection mechanism includes an infrared transmitter 91 fixedly installed on one side of the slide plate 4 and an infrared receiver 92 fixedly installed on the opposite side of the slide plate 4. The infrared light axis emitted by the infrared transmitter 91 of any set of equipment is aligned with the suspension centerline of the through-hole jacks 5 of that set of equipment. With a precisely calibrated fixed relative position relationship, during the actual collimation and positioning operation, there is no need to use cumbersome external space measuring instruments. It is only necessary to adjust each set of slide plates 4 through the push-pull mechanism 6 to ensure that the infrared beam emitted by each set of infrared transmitters 91 can be accurately received and captured by the infrared receivers 92 on the next set of lifting frames along the axis. This means that when the infrared light paths of 40 sets of equipment are connected and captured in a chain between adjacent equipment, it can be quickly determined and ensured that the suspension center lines of the through-hole jacks 5 on these 40 sets of lifting frames are completely kept on the same straight axis, which greatly simplifies the difficulty of multi-point alignment and improves the positioning accuracy.

[0041] Optionally, a controller is also included. The controller is electrically connected to the infrared receivers 92 and the push-pull mechanism 6 in the multiple sets of devices. The controller is used to control the corresponding push-pull mechanism 6 to drive the slide plate 4 to move horizontally according to whether the infrared receivers 92 receive infrared light signals emitted by the infrared transmitters 91 of the adjacent sets of devices, until the infrared receivers 92 of the multiple sets of devices all receive the corresponding infrared light signals, so as to realize the rapid positioning control of the through-hole jacks 5 in the multiple sets of devices on the same axis.

[0042] In this embodiment, for the realization of digital multi-group linkage positioning control, the equipment is also equipped with an industrial-grade central controller. The central controller is electrically connected to each infrared receiver 92 in these 40 groups of equipment and the hydraulic electromagnetic proportional valve of each push-pull mechanism 6. In the actual axis adjustment operation, the central controller continuously monitors the signal reception status of each infrared receiver 92 in real time. When it is determined that the infrared receiver 92 of a certain group of lifting frames fails to receive the infrared light signal emitted by the adjacent infrared transmitter 91, it indicates that the corresponding jack has deviated from the predetermined axis. The controller will automatically output the corresponding electrical control signal according to the feedback status, drive the hydraulic cylinder 61 in the corresponding push-pull mechanism 6 of that group to make a slight displacement adjustment, thereby driving the slide plate 4 to move in the slide groove 3 to correct the deviation, until the infrared receiver 92 of that group of equipment can stably receive the corresponding infrared light signal. Finally, all 40 groups of equipment infrared receivers 92 receive the corresponding infrared light signal, thereby realizing the rapid and automated closed-loop positioning control of the through-hole jacks 5 on the same axis of multiple lifting frames, which significantly improves the effect of multi-point linkage.

[0043] Optionally, the bottom end of the column 1 is fixedly connected to a supporting bracket, and the column 1 is made of H-beam steel, the supporting bracket is a double H-beam steel structure, and the column 1 and the supporting bracket are butt welded with a full penetration bevel.

[0044] In this embodiment, for the lowest foundation anchoring node of the entire heavy-duty lifting equipment, the bottom end of the column 1 is fixedly connected to a load-bearing support bracket made of thick steel plates. In order to meet the ultimate bearing load requirements brought about by the multi-point coordinated lifting of the steel-wood main truss weighing thousands of tons, the material of the column 1 is specifically limited to high-strength H-beams with a large cross-sectional area. The support bracket is specifically designed as a double-section H-beam structure with higher rigidity, which greatly enhances the compressive and bending section modulus of the base node. At the same time, the lower end face of the column 1 and the upper surface of the support bracket are rigidly welded using a full penetration bevel butt welding process, and the weld quality must meet the first-level flaw detection standard. Since the entire suspended lifting equipment will ultimately transfer all heavy loads, tensions, and adverse factors such as wind loads to the bottom during operation, the double-section support bracket with full penetration welding can evenly and safely distribute the concentrated load to the main structure column 1 or the concrete foundation embedded parts below, eliminating the safety hazards of base instability or weld tearing from the source and ensuring the smooth implementation of the entire lifting project.

[0045] While the present invention has been disclosed above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the scope of protection of the present invention.
