Description

Technical Field

[0001] This invention belongs to the technical field of pipe stacking protection equipment, specifically relating to a large pipe stacking anti-tipping device. Background Technology

[0002] Large pipes, as core materials in infrastructure projects, are widely used in various engineering projects such as water supply and drainage, heating networks, power conduits, and municipal sewage. After arriving on site, the pipes need to be temporarily stacked and stored in an orderly manner, and then used one by one as construction progresses. Due to their hollow columnar structure, high self-weight, and narrow contact support surface, large pipes have poor stacking stability and are considered high-risk materials for on-site storage. Preventing tipping and collapse is a key aspect of on-site safety management.

[0003] In existing technologies, the fixing structures for large pipe stacking are mostly passive limiting support structures. Mainstream solutions include wooden padding supports, fixed frame supports, single-sided diagonal bracing reinforcement, and tail-end counterweight reinforcement. These traditional protective structures have significant structural defects in practical construction applications and cannot meet the safety protection and efficient construction requirements of modern construction sites. Firstly, traditional support structures are all rigid passive limiting structures, which can only fix and support the pipes and lack the ability to detect the center of gravity and actively correct deviations. During pipe stacking, factors such as pipe placement deviations, uneven ground settlement, continuous outdoor wind disturbances, and subsequent stacking of pipes can easily cause the pipe's center of gravity to shift to one side. Traditional rigid supports cannot detect these deviations in real time, nor can they adjust and correct the shifted center of gravity. Small tilts accumulate, eventually leading to the entire pipe tilting and slipping, causing safety accidents and material losses.

[0004] Secondly, existing pipe stacking supports are integrated fixed structures with a single structural form, which can only be used individually on the ground at the construction site, resulting in low space utilization. Due to the narrow site, complex materials, and limited work area at the construction site, traditional supports cannot stack multiple sets of devices. Construction workers can only stack pipes one by one in a single work area, making it impossible to carry out multi-station simultaneous filling operations. Human resources cannot be fully utilized, and the efficiency of pipe stacking, tidying, and transportation is low, which seriously restricts the progress of project construction.

[0005] Meanwhile, when traditional rigid support structures are used to stack multiple layers of pipes, the pressure load will be directly applied to the surface of the pipe wall without a buffer or dispersion structure. This can easily lead to pressure deformation, local dents, and surface wear of large pipe walls, affecting the sealing and structural integrity of the pipes during subsequent installation and use, and increasing the cost of rework.

[0006] In summary, existing large-scale pipe stacking devices suffer from numerous technical shortcomings, including the inability to automatically correct tilting and prevent tipping, the inability to correct center of gravity shifts, a single operating mode, the inability to perform multi-station simultaneous operations, low site utilization, susceptibility to pressure damage to pipes, and low construction efficiency. These limitations make it difficult to meet the demands for safe, efficient, and large-scale pipe stacking in current large-scale infrastructure projects. Based on these shortcomings, this invention proposes a novel large-scale pipe stacking anti-tipping device, addressing the core pain points of existing technologies. Summary of the Invention

[0007] The purpose of this invention is to provide a large-scale pipe stacking anti-tipping device, solving the technical problems of traditional pipe stacking supports in the prior art that cannot automatically correct deviation and prevent tipping, and cannot support multi-station synchronous operation. This invention uses pressure sensing detection combined with a double-sided independent correction structure to achieve automatic detection and active correction of pipe center of gravity deviation, eliminating the risk of pipe tipping at the source. At the same time, it adopts a modular and stackable structure, supporting multiple sets of devices for synchronous ground filling and hoisting stacking operations, making full use of human resources and site space, greatly improving the efficiency of pipe stacking operations, and dispersing pipe pressure to avoid pressure damage to the pipes.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a large pipe stacking anti-tipping device, comprising an M-frame, a base frame, and a top frame. The M-frame has fixed supports at its bottom. The base frame is installed inside the M-frame. The top frame is installed on the top of the M-frame via a movable structure. A central beam is fixedly installed at the center inside the base frame. A detection beam is provided between the central beam and the base frame, and a pressure sensor is mounted on the top of the detection beam. Correction frames are symmetrically and movably installed on both sides of the central beam. One end of each correction frame has a connecting shaft, and the correction frame is movably connected to the central beam via the connecting shaft. A telescopic rod is hinged to one side of the bottom of each correction frame, and the end of the telescopic rod away from the correction frame is hinged to the top of the supports. A battery and a controller are installed on both sides of the M-frame. Limiting protrusions are provided at the top of both ends of the top frame. These limiting protrusions match the shape of the bottom of the base frame, allowing the bottom of another set of devices to be embedded for limiting. A slot is provided on one side of the bottom of the top frame, and a connecting hinge is mounted on the other side of the bottom of the top frame. The top frame is movably connected to the top of the M-frame via the connecting hinge.

[0009] Furthermore, the detection beam is arranged laterally inside the base frame, and the pressure sensor is fixedly embedded on the upper surface of the detection beam, with the detection end of the pressure sensor facing upwards.

[0010] Furthermore, the correction frame is an inclined support structure, with the correction frames on both sides symmetrically arranged on the left and right sides of the central beam, and the correction frames on both sides can rotate and swing independently around the connecting shaft.

[0011] Furthermore, both ends of the telescopic rod are hinged, with the telescopic end of the telescopic rod hinged to the bottom of the correction frame and the fixed end of the telescopic rod hinged to the top of the support leg.

[0012] Furthermore, the top frame is designed to flip and open via a connecting hinge. When the top frame is closed, its bottom slot engages and limits the movement with the top end of the M frame.

[0013] Furthermore, a support rod is hinged to the outside of the M-frame via a hinge, and a support foot is hinged to the outside of the base frame via a hinge. The inner side of the support foot is provided with locking teeth, and a magnetic block is embedded inside the support foot. The end of the support rod engages with the inner side of the locking teeth and magnetically attracts the magnetic block. When the support rod and support foot are unfolded, they form a triangular support structure. The support height of the support rod can be adjusted by matching different locking teeth positions. The support foot can be flipped upwards and magnetically fixed to the outside of the support rod by the magnetic block for storage.

[0014] Furthermore, the battery and controller are respectively fixedly mounted on the mounting brackets on the left and right sides of the M frame, and the battery and controller are symmetrically distributed.

[0015] Furthermore, the pressure sensor and the telescopic rod are electrically connected to the controller, and the battery provides power to the controller, the pressure sensor, and the telescopic rod.

[0016] Furthermore, the M-frame is an integrated M-shaped frame structure, with the legs symmetrically fixed to both sides of the bottom end of the M-frame, and a hollow placement cavity is formed inside the M-frame to accommodate the base frame and the pipes.

[0017] Furthermore, the base frame is a rectangular frame structure, and the central beam is horizontally fixed in the middle of the base frame, dividing the interior of the base frame into symmetrical placement areas.

[0018] In summary, the present invention has the following beneficial technical effects: This invention employs pressure detection combined with a dual-sided independent adaptive correction structure. The pressure sensor inside the base frame detects the force difference between the two sides of the pipe in real time, accurately determining the pipe's center of gravity offset. In conjunction with the controller, it independently controls the extension and retraction of the telescopic rod on one side, driving the correction frame to swing and lift around the axis, automatically correcting the offset pipe's center of gravity towards the center, achieving active correction and preventing tipping. This fundamentally solves the safety hazards of center of gravity offset, cumulative tilting, and collapse of large pipe stacks, providing protection and safety far superior to traditional passive supports.

[0019] This invention adopts a modular and stackable structural design, allowing multiple sets of devices to be arranged during construction. Multiple construction workers can simultaneously complete the pipe filling operation on the ground. After filling, the pipes are hoisted and stacked in a unified manner, which completely solves the problem of insufficient manpower and low work efficiency caused by limited space. It significantly improves the construction efficiency of pipe stacking, tidying, and transportation, and is suitable for large-scale construction scenarios. In addition, when multiple layers of pipes are stacked, the pressure load will not be directly applied to the surface of the pipe wall, thus improving the protection effect of the pipeline.

[0023] According to the technical solution of the present invention, without changing the essential spirit of the present invention, those skilled in the art can propose various interchangeable structural methods and implementations. Therefore, the following detailed embodiments and accompanying drawings are merely exemplary descriptions of the technical solution of the present invention, and should not be regarded as the entirety of the present invention or as a limitation or restriction of the technical solution of the present invention.

[0024] The following is in conjunction with the appendix Figure 1 To be continued Figure 9 The invention will be further illustrated by the following specific embodiments: Example 1: Single device placed independently for operation.

[0025] This embodiment discloses a single-device independent structure for a large pipe stacking anti-tipping device, which is suitable for on-site stacking, temporary storage, and single-area protection operations of a small number of pipes at construction sites. It can realize independent placement of a single device, automatic center of gravity detection, adaptive correction to prevent tipping, and is suitable for medium, small and large pipes and the fixed-point stacking protection needs of a single set of pipes.

[0026] like Figures 1 to 3 As shown, in this embodiment, the main body of the device consists of an M-frame 1, a base frame 2, a top frame 3, a correction frame 4, a telescopic drive structure, a detection and sensing structure, and an electrical control structure. The M-frame 1 is an integrated M-shaped steel frame structure with high overall structural strength and strong load-bearing stability. Symmetrical support legs 101 are fixedly installed on both sides of the bottom of the M-frame 1, allowing the entire device to be placed stably on the ground. The interior of the M-frame 1 forms a hollow cavity, providing a neat space for the installation of the base frame 2 and the placement of pipes. Mounting brackets are fixedly installed on the outer walls of the left and right sides of the M-frame 1. The left bracket fixes the battery 5, and the right bracket fixes the controller 6. The symmetrically arranged mounting structure on both sides balances the overall center of gravity of the device, preventing tilting caused by unilateral counterweight shift. It also achieves an integrated layout of the electrical control and power supply structures, resulting in a neat and simple equipment layout.

[0027] like Figures 1 to 2 As shown, a base frame 2 is fixedly embedded inside frame M1. Base frame 2 adopts a rectangular frame structure. The frame structure can minimize its own weight, improve space utilization, and ensure overall load-bearing strength. A central beam 201 is horizontally fixed in the middle of the frame of base frame 2. The central beam 201 serves as the core load-bearing and hinge base, dividing the interior of base frame 2 into symmetrical independent placement areas on the left and right sides. Single large pipes can be placed in each area, enabling simultaneous stacking and protection of two pipes and improving the utilization rate of a single device. A detection beam 202 is horizontally erected between the central beam 201 and the inner side frame of base frame 2. The detection beam 202 is a rigid load-bearing beam, and multiple pressure sensors 203 are embedded and fixed on its upper surface. The detection ends of the pressure sensors 203 are arranged upwards, directly corresponding to the bottom support area of ​​the pipe. It can collect pressure data on both sides of the bottom of the pipe in real time, accurately reflecting the stress distribution and center of gravity offset of the pipe.

[0028] like Figure 1 , Figure 3 and Figure 6 As shown, symmetrical alignment frames 4 are mounted on both sides of the central beam 201. The alignment frame 4 is an inclined support structure, with its upper end hinged to the side wall of the central beam 201 via a connecting shaft 402, allowing it to rotate freely around the connecting shaft 402. The two alignment frames 4 move independently without interference. A telescopic rod 401 is hinged to the inclined bottom end of the alignment frame 4. The telescopic rod 401 is an electrically driven telescopic structure; its movable end is hinged and fixed to the bottom of the alignment frame 4, and its fixed end is hinged and fixed to the top of the support leg 101 at the bottom of the M-frame 1, forming a stable triangular drive support structure. Through the telescopic movement of the telescopic rod 401, the alignment frame 4 can be driven to swing and lift around the connecting shaft 402, achieving adaptive adjustment of the single-sided support height of the pipe. During design, the area of ​​the alignment frame 4 can be appropriately increased to provide stable support.

[0029] like Figure 1 , Figure 2 and Figure 5 As shown, the top frame 3 is hinged to the top of the M frame 1 via a connecting hinge 303. The connecting hinge 303 enables the top frame 3 to flip open and close, facilitating quick loading and unloading of pipes. A slot 302 is integrally formed on one side of the bottom of the top frame 3. When the top frame 3 is fully closed, the slot 302 engages with the top end of the M frame 1 to lock and fix the top frame 3, preventing accidental opening during stacking and ensuring the overall structural stability. The top of both ends of the top frame 3 has integrally formed protruding limiting protrusions 301. The outline of the limiting protrusions 301 precisely matches the bottom outline of the base frame 2, providing a limiting basis for subsequent stacking of multiple devices. When a single device is used independently, the limiting protrusions 301 do not participate in the operation and are only used as structural spares.

[0030] The electrical control system in this embodiment adopts an integrated self-powered structure. The battery 5 provides continuous power to the entire device, eliminating the need for external mains power and making it suitable for temporary outdoor storage sites. The pressure sensor 203 and the double-sided telescopic rods 401 are electrically connected to the controller 6. The controller 6 has a built-in data processing module and control program, which can receive the double-sided pressure data collected by the pressure sensor 203 in real time, calculate the pressure difference between the two sides in real time, and accurately determine the direction and degree of the pipe's center of gravity shift.

[0031] The independent working process of this single device in this embodiment is as follows: the construction personnel flip open the top frame 3 and place the large pipes to be stacked in the placement areas on the left and right sides inside the bottom frame 2. The bottom of the pipes is attached to the detection beam 202 and the pressure sensor 203. After placement, the top frame 3 is flipped closed and locked and fixed by the slot 302, so as to realize the closed and protective stacking of the pipes.

[0032] During the stacking and static placement of the pipes, pressure sensor 203 continuously collects pressure data from both sides of the bottom of the pipes in real time and transmits it to controller 6. When the center of gravity of the pipes shifts to one side due to placement deviation, wind disturbance, or slight ground subsidence, the pressure on one side of the pipe increases while the pressure on the other side decreases, creating a significant pressure difference. Once controller 6 detects that the pressure difference exceeds a preset safety threshold, it automatically determines that the pipes have tilted or shifted. It then controls the extension rod 401 on the shifted side to extend, pushing the corresponding correction frame 4 to swing upwards around the connecting shaft 402, supporting and raising the lower side of the pipe. This gradually corrects the center of gravity of the pipes towards the center of the base frame 2 until the pressure data on both sides tends to balance and the pipes return to a vertical and centered state, completing the automatic correction and anti-tipping operation. Once the center of gravity of the pipes is balanced, controller 6 controls the extension rod 401 to stop moving and maintain its current state, continuously and stably supporting the pipes and providing real-time dynamic protection to eliminate the risk of pipe tilting or tipping at the source.

[0033] This embodiment features a single-device independent use mode, with a compact structure, simple operation, and precise protection. It requires no real-time manual monitoring and adjustment, and can achieve fully automatic monitoring and correction protection for pipe stacking. It is perfectly suited for the stacking protection scenarios of small amounts of pipes, scattered locations, and temporary storage on construction sites, and effectively solves the problems of traditional supports being unable to actively correct deviations and having poor protection safety.

[0034] Example 2: Stacking and placing multiple devices.

[0035] This embodiment, based on the single-device basic structure of Embodiment 1, discloses the modular stacking operation mode of the present invention. It is applicable to scenarios involving the centralized stacking of large quantities of pipe materials on construction sites, large-scale organization, and pre-operation for hoisting and transportation. It primarily addresses the industry pain points of traditional pipe material stacking operations, such as limited space, inability of multiple personnel to work simultaneously, low manpower utilization, and low construction efficiency. This is a concrete manifestation of the core innovation of the present invention in efficient construction. In this embodiment, the basic structure, correction principle, electrical control logic, and opening / closing structure of a single device are completely consistent with Embodiment 1. The core difference lies in the modular stacking and coordination structure of multiple devices and the batch operation process.

[0036] like Figures 4 to 7 As shown, this embodiment uses multiple sets of anti-tipping devices of the same specifications in combination. Relying on the matching structure between the protruding limiting protrusion 301 on the top of the top frame 3 and the bottom of the base frame 2, the precise alignment and stacking of the upper and lower multi-layer devices are achieved. The limiting protrusions 301 at both ends of the top frame 3 are symmetrical protruding structures. The protrusion position and outline size are perfectly matched with the groove outline of the bottom of the base frame 2, so that the base frame 2 of the upper device can be precisely embedded between the limiting protrusions 301 of the top frame 3 of the lower device, forming a nested limiting structure. This effectively limits the horizontal offset and left and right sway of the upper and lower devices, ensures the overall stability of the multi-layer stacked structure, and avoids misalignment and collapse of the devices after stacking.

[0037] The core operational logic of this embodiment is "distributed synchronous filling on the ground and overall layered hoisting and stacking," completely overturning the inefficient traditional method of stacking pipes one by one and area by area. The specific workflow is as follows: Based on the number of workers and available space, multiple sets of vacant anti-tipping devices are simultaneously deployed at the construction site. Multiple workers are assigned to each set of devices, independently completing the pipe filling operation for each set. Each set of devices operates without interference and is constructed synchronously. Multiple workers simultaneously perform pipe handling, placement, top frame closure, and equipment self-inspection, fully utilizing human resources and avoiding the problem of idle manpower in single-station operations.

[0038] like Figures 4 to 7 As shown, after the pipes of each unit are filled, the center of gravity is independently checked and the initial correction is performed to ensure that the pipes inside the single unit are stacked in the center and in a stable state. Then, the single unit is hoisted as a whole by hoisting equipment, and the filled units are stacked layer by layer. During the stacking process, the bottom of the base frame 2 of the upper unit is precisely aligned with the limiting protrusion 301 of the top frame 3 of the lower unit. The limiting protrusion 301 achieves full horizontal limitation, preventing inter-layer offset and shaking, and the multi-layer modular pipe stack is formed by stacking layer by layer.

[0039] Compared to traditional direct stacking of pipes, the modular stacking structure in this embodiment offers multiple technical advantages. First, during multi-layer stacking, the entire load of the upper layer is transferred to the ground through the frame structure of M-frame 1, base frame 2, and top frame 3. The load is borne by the overall steel frame structure and does not directly act on the surface of the stacked pipes, completely avoiding the problems of compression deformation and pipe wall damage caused by multi-layer pipe stacking, thus comprehensively protecting the structural integrity of the pipes. Second, each layer has independent pressure detection and automatic correction functions. After stacking, each layer can independently monitor the center of gravity of the internal pipes and independently perform adaptive correction for any deviation or tilting of a single layer of pipes. There is no interference between layers, providing multi-layered protection and a comprehensive safety net, significantly improving the overall stacking stability and safety.

[0040] Meanwhile, the modular stacking structure can significantly save space on the construction site. Traditional single-layer flat stacking has a large footprint and low space utilization. This embodiment adopts a three-dimensional stacking mode, which can realize the centralized and orderly stacking of large quantities of pipes in a limited space, greatly improving the space utilization and adapting to the operational needs of narrow construction sites. The stacked modular pipe stack has a regular structure and strong stability, and can be directly used as a whole unit for hoisting and transportation without the need for secondary pipe straightening, greatly simplifying the pipe transportation process and improving material transportation efficiency.

[0041] In this embodiment, during the stacking operation, the electrical control systems of each device operate independently, and the batteries 5 of each group of devices are independently powered, unaffected by the number of stacking layers. This allows for continuous real-time pressure monitoring, dynamic center of gravity correction, and all-weather anti-tipping protection. Even under multi-layer stacking and heavy load conditions, the stacking accuracy and safety of a single group of pipes can still be guaranteed. Simultaneously, the locking and limiting structure of the slots 302 on the top frame 3 ensures the sealing stability of each layer of devices, preventing the top frame 3 from loosening and pipes from falling off during stacking, further enhancing overall operational safety.

[0042] This embodiment, through its modular and stackable structural design, thoroughly optimizes the stacking process of large pipes from the construction mode perspective. It solves a series of industry pain points in the existing technology, such as limited space, wasted manpower, low work efficiency, easy damage to pipes, and poor stacking stability. It realizes an integrated and efficient construction mode of "multi-person simultaneous operation, batch filling, three-dimensional stacking, overall transportation, and intelligent protection". It is suitable for the engineering needs of large-scale stacking, storage, and transportation of various large pipes and has extremely high engineering application value and promotion value.

[0043] Example 3 This embodiment, based on the basic structures of Embodiments 1 and 2, adds a lateral auxiliary support structure. It is suitable for operation scenarios with extremely high requirements for the overall stability of the equipment, such as outdoor open-air stacking, soft ground, windy weather conditions, reinforcement of the bottom layer of ultra-high stacked devices, and long-term static storage. It focuses on solving the technical problems of limited support area of ​​a single bottom support leg, easy settlement on soft ground, weak lateral anti-overturning ability, and large space occupied by idle equipment storage. It further enhances the overall anti-tipping performance of the device, while realizing adaptive height adjustment and seamless folding storage of the support structure.

[0044] like Figure 8 and Figure 9 As shown, the core addition structure in this embodiment is an adjustable triangular support assembly, specifically including a support rod 7 and support feet 8. These two sets of structures are symmetrically arranged on the left and right sides of the M-frame 1, forming a multi-dimensional stable support system in conjunction with the main frame. The support rod 7 is hinged to the outer wall of the M-frame 1, allowing for multi-angle rotation and swinging around the hinge axis. The support feet 8 are hinged to the outer wall of the base frame 2, arranged vertically in relation to the support rod 7. The two work together to complete the support unfolding and folding storage actions.

[0045] like Figure 9As shown, the inner side of the support leg 8 is integrally formed with continuously arranged locking teeth 802. The locking teeth 802 have a stepped limiting structure, which can precisely engage and limit the end of the support rod 7. The locking teeth 802 at different positions correspond to different support unfolding angles and support heights, thereby achieving stepless adjustment of the overall support height. This can adapt to complex working conditions such as slight ground undulations, ground settlement, and fine adjustment of stacking height. At the same time, a magnetic block 801 is embedded and fixed on the support leg 8. The magnetic block 801 is embedded and does not protrude from the surface of the support leg 8. This does not affect the flatness of the ground support, and can achieve magnetic fixation with the metal support rod 7, ensuring the structural stability in the storage state.

[0046] The support deployment process in this embodiment is adapted to the reinforcement of bottom-layer stacking devices. When used on the bottom layer of a single device stacked independently or in a multi-layer stacked device, it can significantly improve the overall anti-overturning and anti-crosswind capabilities. During operation, the support rod 7 is manually flipped outward and the support foot 8 is flipped downward to unfold, so that the bottom of the support foot 8 is completely in contact with the ground. This increases the overall contact support area between the equipment and the ground, changing the limitations of traditional single-leg point support and forming a surface support structure. This effectively avoids equipment tilting problems caused by soft ground subsidence and localized stress sinking. The free end of the support rod 7 is inserted into the corresponding locking teeth 802 on the inner side of the support foot 8. The corresponding locking teeth 802 are selected to lock and fix the device according to the flatness of the ground and the stacking height requirements.

[0047] At this point, the support rod 7, support foot 8, and outer wall of M frame 1 form a closed triangular stable support structure. Relying on the mechanical stability of the triangular structure, it forms a lateral traction support limit for the main body of the device, effectively resisting the lateral thrust of strong outdoor winds and the lateral overturning moment caused by the slight shift of the center of gravity of the pipe. It eliminates the risk of the entire device tipping over from the foundation level of the bottom of the equipment. Together with the pressure detection inside the equipment and the active correction structure of the single-sided correction frame, it forms a dual protection system of bottom mechanical anti-tilting + internal intelligent correction, which greatly improves the safety and stability of large pipe stacking.

[0048] Meanwhile, by matching the different locking teeth 802, the unfolding angle and support height of the support rod 7 can be flexibly adjusted. For uneven construction site ground, the support height of the left and right support structures can be adjusted separately to level and correct the main body of the equipment, avoiding the inherent tilt of the equipment due to uneven ground, reducing the probability of pipe stacking deviation from the source, and adapting to the needs of various complex site operations.

[0049] When the device is in operation and needs to be transported, stored, or left idle, the support structure can be quickly folded and stored, making the storage process simple and fast. First, detach the end of the support rod 7 from the inside of the retaining teeth 802, flip the support rod 7 upwards to fold it up, and then flip the support foot 8 upwards so that the magnetic block 801 on the support foot 8 adheres and attracts to the side wall of the support rod 7. The magnetic attraction force achieves the adhesion and fixation between the support foot 8 and the support rod 7, preventing the structure from becoming loose, wobbling, or protruding after storage. After storage, the entire support structure completely fits the outside of the main body of the equipment, with no protruding structure and no extra space occupied. The overall equipment is neat and compact, greatly reducing the floor space occupied for storage, transportation, and storage, and solving the defects of traditional auxiliary support structures that cannot be stored, are permanently protruding, and are inconvenient to transport.

[0050] This embodiment is fully compatible with both the single-device independent operation mode of Embodiment 1 and the multi-device stacking operation mode of Embodiment 2. In multi-layer stacking, only the bottom device deploys its lateral triangular support structure, while the upper devices do not need to be deployed. This ensures the stability of the bottom layer of the overall stacked structure without affecting the limiting fit and hoisting operations of the multi-layer stack. Furthermore, the added support structure adopts a hinged modular design, which does not interfere with all the original functions of the equipment's top frame opening and closing, pipe loading and unloading, pressure detection, automatic correction, and inter-layer limiting stacking, demonstrating extremely strong structural adaptability.

[0051] Compared to traditional fixed support structures, the adjustable magnetic folding triangular support structure in this embodiment has multiple advantages, including adjustable height, strong site adaptability, excellent anti-overturning performance, foldable storage, and no space redundancy. It effectively makes up for the stability shortcomings of the original equipment in complex sites, windy conditions, and long-term static stacking scenarios, further broadening the applicable scenarios of the equipment and improving its overall practicality and engineering promotion value.

[0052] Working principle: The overall working principle of this invention is divided into two parts: the single-device intelligent correction and anti-tipping principle and the multi-module stacking high-efficiency operation principle. The overall structure is reasonably designed, the working logic is clear, and the degree of automation is high, which can fully meet the safety protection and efficient construction needs of large pipe stacking.

[0053] The working principle of the single-device anti-tipping and correction system is as follows: After the device is stably placed on the ground, construction personnel open and close the top frame 3 to complete the pipe loading. The bottom of the pipe is supported on the surface of the pressure sensor 203 above the detection beam 202. The pressure sensor 203 collects the pressure signals of the pipe's two sides in real time and transmits them to the controller 6. The controller 6 accurately determines the pipe's center of gravity offset state through the pressure difference. When the pipe's center of gravity shifts in any direction or degree, the controller 6 precisely matches the telescopic rod 401 on the offset side, controlling the telescopic rod 401 to extend and retract, driving the corresponding side correction frame 4 to swing and lift around the connecting shaft 402. This adaptively adjusts the support on the lower side of the pipe, gradually correcting the pipe's center of gravity to the center position, achieving dynamic automatic correction without manual intervention, and preventing the pipe from tilting or tipping over in real time. The two sides of the correction frame 4 are independently controlled and can adapt to various complex working conditions such as unilateral offset, bidirectional offset, slight tilt, and large tilt, providing accurate correction, rapid response, and stable protection.

[0054] Regarding the principle of multi-module stacking: relying on the matching structure of the protruding limiting protrusion 301 on the top of the top frame 3 and the bottom of the base frame 2, precise nesting and stacking of multiple sets of devices can be achieved, with reliable inter-layer limiting and strong structural stability. Through the operation mode of simultaneous loading of multiple sets of devices on the ground and subsequent overall stacking, the limitations of traditional single-station operations are broken, making full use of manpower and site resources and significantly improving the efficiency of pipe stacking. At the same time, the frame-type stacking structure can distribute the load, avoiding pressure damage to the pipes, and the independent intelligent correction system for each layer can achieve all-round safety protection for multiple layers of pipes, balancing construction efficiency and stacking safety.
