Description

Technical Field

[0001] This invention relates to the field of photovoltaic module hoisting equipment technology, specifically a stable photovoltaic module distributed hoisting device. Background Technology

[0002] Photovoltaic modules, as the core carrier of new energy photovoltaic power generation systems, are an important foundation for the large-scale application of clean energy and are widely used in various photovoltaic power station scenarios such as industrial and commercial rooftops, mountain slopes, agricultural-photovoltaic integration, and fishery-photovoltaic integration. With the rapid development of the photovoltaic industry, the construction of photovoltaic power stations is becoming more large-scale, high-altitude, and complex in terms of scenarios. Most photovoltaic modules need to be hoisted and installed under special working conditions such as high-altitude supports, elevated structures, and complex mountain slopes.

[0003] Currently, the industry generally uses cranes in conjunction with traditional lifting equipment to complete the high-altitude hoisting of photovoltaic modules. However, the existing hoisting technology and supporting lifting equipment have simple structures, limited functions, and poor adaptability and stability. In actual construction, many technical defects have been exposed, which seriously affect the safety, accuracy and construction efficiency of photovoltaic module hoisting.

[0004] First, existing photovoltaic (PV) hoisting equipment lacks effective attitude leveling and anti-sway buffer structures. During high-altitude hoisting operations, PV modules are susceptible to factors such as high-altitude winds, hoisting inertia, and crane operational deviations, leading to significant swaying, tilting, and shaking of the modules. Simultaneously, the rigid impact vibrations generated during hoisting and positioning cannot be effectively mitigated, easily causing scratches and collisions between PV modules and surrounding supports and building structures. Furthermore, it can easily lead to hidden damage such as microcracks in the internal cells of the PV panels and frame distortion, significantly reducing the finished product qualification rate and lifespan of the PV modules. Moreover, traditional hoisting equipment cannot adaptively correct the attitude based on the module's tilt, making it difficult to correct attitude deviations during hoisting. This greatly increases the difficulty of high-altitude alignment and installation, and fails to meet the stable hoisting operation requirements under complex windy conditions.

[0005] Secondly, existing hoisting structures mostly employ single-point or small-scale multi-point concentrated force hoisting methods, which suffer from the core problem of uneven force distribution. Traditional hoisting tools often use rigid ropes and hard clamps to fix photovoltaic modules, concentrating the hoisting load on a local frame of the module, which easily leads to stress concentration. Long-term hoisting can cause the photovoltaic frame to be squeezed and deformed, and the panel surface to be damaged by pressure. At the same time, the concentrated force hoisting method cannot adapt to the force distribution requirements of photovoltaic modules of different sizes, resulting in uneven overall lifting force on the module and easy displacement and tilting during hoisting. Furthermore, traditional rigid clamping structures have poor fit and cannot achieve flexible adaptation and fixation, providing extremely poor protection for photovoltaic modules of different sizes, which can easily cause wear and damage to the panel surface, making it difficult to meet the requirements of safe and stable hoisting construction of large-scale photovoltaic modules. Finally, the positioning adaptability and disassembly efficiency of existing photovoltaic hoisting tools are relatively low. Most conventional hoisting tools on the market are fixed structures with simple limit adjustment mechanisms, unable to quickly adapt to photovoltaic modules of different lengths and widths. Different hoisting tools are required for different models of photovoltaic modules, resulting in poor equipment versatility and high adaptation costs. Furthermore, the positioning and limiting methods of traditional hoisting tools are cumbersome, often relying on manual alignment and bolt tightening. The clamping and disassembly processes are complex, time-consuming, and labor-intensive. High-altitude manual operation is difficult and carries high safety risks. Moreover, the lack of an adaptive pressure limiting structure after positioning makes it prone to problems such as module loosening, displacement, and offset during hoisting. Poor installation alignment accuracy severely restricts the overall construction progress and installation quality of photovoltaic power plants, failing to meet the demands of efficient, precise, and universal hoisting construction for modern photovoltaic projects.

[0006] In summary, existing photovoltaic module hoisting devices suffer from numerous technical shortcomings, including poor hoisting stability, insufficient anti-sway buffering capacity, uneven stress on modules, poor protection effect, and weak specification adaptability. These limitations make them unsuitable for the safe and efficient high-altitude hoisting of photovoltaic modules under current complex operating conditions. Therefore, there is an urgent need to design a stable distributed hoisting device for photovoltaic modules to address the aforementioned deficiencies in existing technologies. Summary of the Invention

[0007] In view of this, a stable photovoltaic module distributed hoisting device is proposed to solve the problems existing in the prior art.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a stable photovoltaic module distributed hoisting device, comprising: a crane hook, and further comprising: a first component; The first component includes a universal joint, which is hung on the crane hook via a hanging ring. A connecting frame is fixedly connected to the bottom of the universal joint, and damping buffers are symmetrically fixedly connected to the bottom of the connecting frame. Each damping buffer has an auxiliary square cavity fixedly connected to its bottom. The bottom of the two auxiliary cavities is fixedly connected to an auxiliary plate. The four corners of the bottom surface of the auxiliary plate are fixedly connected to electrically controlled telescopic support rods. The telescopic ends of the electrically controlled telescopic support rods are hinged and fixed with buffer pads. An inclination sensor is set below the auxiliary plate. The inclination sensor is used to detect the attitude angle of the hoisting frame in real time and generate an attitude signal to feed back to the controller. The controller drives the electrically controlled telescopic support rods to perform independent telescopic adjustment based on the signal, forming a closed-loop dynamic leveling of the hoisting frame.

[0009] The second component is preferred; A hoisting frame is provided below the auxiliary plate, the tilt sensor is fixed to the side wall of the hoisting frame, and the side of the buffer pad away from the electrically controlled telescopic support rod is fixed to the upper surface of the hoisting frame; The side wall of the hoisting frame is symmetrically fixedly connected with a slotted base. The slotted base has two symmetrical fixed anchor points. Flexible slings are inserted into the slots of the two slotted bases in the set of fixed anchor points. Vacuum suction cup assemblies are symmetrically fixedly connected to the hoisting frame.

[0010] As a preferred option, a third component is also included; The bottom surface of the hoisting frame is symmetrically provided with a sliding groove, and a positioning slider is slidably connected in the sliding groove. A column cavity is provided in the positioning slider, and a spring is fixedly connected in the column cavity. A pressure bar is fixedly connected to the end of the spring away from the fixed point, and the pressure bar slides in the column cavity through the column. A silicone plug is fixedly connected inside the auxiliary square cavity, as shown in the attached diagram. Figure 6 A sliding frame is slidably installed inside the square cavity, and a limit baffle is fixedly connected to the bottom of the sliding frame; the positioning slider and the sliding frame are independently slidable and adjusted along the lateral side of the hoisting frame, together forming an adaptive limit frame for the four sides of the photovoltaic module; after the limit adjustment is completed, the attitude leveling of the hoisting frame and the limit structure form a geometric centering match, ensuring that the center of gravity of the module coincides with the hoisting center.

[0011] Preferably, the upper surface of the auxiliary plate is symmetrically provided with electrically controlled telescopic devices via vertical plates. The front end of the electrically controlled telescopic device is hinged with a through tube, and through holes are equidistantly opened on the through tube. Insertion parts are inserted into the through holes.

[0012] An auxiliary tube is fixedly connected to the sliding frame, and a guide tube is fixedly connected to the bottom surface of the auxiliary tube. The insertion tube is slidably adapted to the guide tube.

[0013] Preferably, the universal joint, damping buffer, and buffer pad constitute a sway impact torque buffer group.

[0014] Preferably, the electrically controlled telescopic support rod and the tilt sensor constitute a hoisting and leveling assembly.

[0015] Preferably, the vacuum suction cup assembly consists of suction cups and tubing, with the tubing connected to an external vacuum pump.

[0016] Preferably, the positioning slider, spring, and pressure bar constitute limiting group A; the sliding frame and limiting baffle constitute limiting group B.

[0017] Compared with the prior art, the present invention provides a stable photovoltaic module distributed hoisting device, which has the following beneficial effects: 1. The design of the first component in this invention provides the following advantages: Achieving automated attitude leveling and eliminating hoisting tilt deviations: This component can adapt to the tilt state of the photovoltaic panel and complete dynamic leveling correction throughout the entire process of high-altitude hoisting of photovoltaic modules. It relies on tilt sensors to collect the tilt angle data of the hoisting frame on which the photovoltaic panel is located in real time, and cooperates with the electronically controlled telescopic support rod to perform precise micro-attitude adjustments. It can actively correct the tilt deviations generated during hoisting, solve the problem that traditional hoisting tools cannot adaptively level and the module's attitude is skewed, and ensure that the photovoltaic panel surface always remains in a regular and level state during the hoisting process, greatly reducing the difficulty of high-altitude alignment and installation. Eliminating hoisting torque and achieving multi-directional flexible adaptation: Through the structural characteristics of the universal joint, it is possible to achieve flexible reversal at multiple angles during hoisting, effectively releasing and eliminating the torsional torque generated during hoisting, preventing photovoltaic modules from deflecting or misaligning due to the torque of the hoisting equipment, eliminating the hidden deformation of the modules caused by the torque, and making the hoisting and transportation process smoother. Highly efficient buffering and shock absorption, comprehensively suppressing hoisting sway: With the synergistic cooperation of damping buffers and buffer pads, it can effectively absorb the swaying potential energy, impact load and swing torque generated by wind disturbance, hoisting start and stop, and alignment contact during high-altitude operations, effectively suppressing the multi-dimensional swaying of photovoltaic modules in front and behind, left and right, improving the shortcomings of traditional hoisting devices with large sway amplitude and poor stability, and making the photovoltaic modules stable and controllable throughout the process.

[0018] 2. The design of the second component in this invention provides the following advantages: Adopting a multi-point distributed load-bearing structure to avoid local stress concentration: This module abandons the traditional single-point or few-point concentrated hoisting load-bearing form and adopts a multi-point distributed hoisting layout, which can evenly distribute the overall load of the photovoltaic module, making the overall stress distribution of the photovoltaic module more balanced during the hoisting process. It effectively solves the problem of local concentrated load of traditional hoisting tools, avoids excessive load on local parts of the photovoltaic module, avoids structural damage caused by stress concentration, and ensures the overall structural integrity of the photovoltaic module. Flexible bonding and clamping protection to avoid damage to the module under pressure: This module achieves flexible bonding and adsorption to the photovoltaic panel surface through a vacuum suction cup assembly, combined with flexible slings for support; the flexible slings and vacuum suction cups contact the frame and back of the photovoltaic module, resulting in gentle overall lifting force. It abandons the traditional rigid lifting tool's hard pressure and clamping fixing method, and will not exert pressure or squeezing force on the photovoltaic panel surface and frame. It can effectively prevent photovoltaic panel wear and pressure damage, as well as frame deformation and warping, and significantly reduce the breakage rate of photovoltaic modules during the lifting process, achieving non-destructive lifting operation; Enhance overall hoisting stability and adapt to large-area module transfer: Through a multi-point balanced force distribution layout, the photovoltaic modules are subjected to uniform and balanced forces during hoisting and lifting, effectively avoiding module offset and tilting during hoisting, greatly improving the overall rigidity and structural stability of the hoisting, and enabling the smooth completion of the hoisting and transfer of large-size and large-area photovoltaic modules, adapting to the efficient hoisting construction needs of large-scale photovoltaic power plants.

[0019] 3. The design of the third component in this invention brings the following advantages: Achieving multi-specification adaptive adaptation and strong device versatility: This component relies on the sliding adjustment structure of the sliding frame and positioning slider to adaptively adjust the limit distance according to the different length and width dimensions of photovoltaic modules. It can quickly adapt to the clamping and positioning requirements of photovoltaic modules of various specifications and models without changing the hoisting tooling. It effectively solves the problems of fixed structure, poor adaptability and weak versatility of traditional hoisting tools, and greatly reduces the cost of replacing construction equipment and preparation time. Flexible and elastic limiting fit, stable positioning and prevention of displacement and loosening: The spring and the pressure bar form an elastic self-adaptive pressure structure, which can flexibly fit and limit the photovoltaic module. This ensures a tight and gapless clamping fit, while avoiding damage to the module caused by rigid compression. Combined with the limiting baffle, it forms an all-round limiting structure, which can stably constrain the photovoltaic module and effectively prevent the module from moving, shifting, or loosening during hoisting, ensuring the stability and reliability of the clamping state. Precise centering and positioning effectively improves installation accuracy: The components have the ability to automatically center and limit, and accurately align. They can complete the precise centering and positioning of photovoltaic modules during clamping, effectively improving the problems of large positioning deviation and center of gravity shift of traditional hoisting tools. This ensures the accurate positioning of photovoltaic modules during high-altitude hoisting and guarantees the safety of subsequent suspended hoisting of photovoltaic modules.

[0020] 4. This invention, through the progressive cooperation of the first, second, and third components via "geometric alignment - attitude leveling - flexible load-bearing," can bring the following benefits: Coordinated positioning and leveling: The third component (positioning slider, limiting baffle) centers and limits the photovoltaic module, ensuring that the module's center of gravity coincides with the geometric center of the lifting frame; the second component (vacuum suction cup, flexible sling) is evenly distributed to bear the load based on this centering benchmark; the first component (tilt sensor, electrically controlled telescopic support rod) then performs high-precision attitude correction based on this. Without the bidirectional adjustable third component, the first component would not be able to eliminate the asymmetrical tilt caused by the center of gravity offset, and the leveling efficiency would be greatly reduced; Coordinated load-bearing and anti-swaying: The second component achieves force distribution through multi-point flexible slings and vacuum suction cups, ensuring that the lifting frame is in a stable state of low stress and high rigidity from the initial lifting stage. This stable state provides an ideal vibration control foundation for the damping buffer and electrically controlled telescopic support rod of the first component, avoiding actuator overload or response delay caused by component swaying or off-center loading. The high-frequency micro-motion leveling capability of the first component, in turn, protects the flexible adsorption interface of the second component, preventing tangential forces generated by swaying from damaging the airtightness of the vacuum suction cups. Functional Integration: The three components work together to achieve a chain of technical effects: "clamping equals centering → centering equals load stabilization → load stabilization equals leveling → leveling equals damage prevention." This effect is not a simple addition of the functions of each component, but rather a result of structural parameter matching and control logic integration, producing the beneficial effects of "improved positioning accuracy and dynamic leveling feasibility, and enhanced robustness of the anti-sway system through flexible load-bearing."

Detailed Implementation

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0025] Example Please refer to Figures 1 to 3 , Figure 5 , Figure 6 As shown: To address the problems mentioned in the technical solutions, this application provides a stable photovoltaic module distributed hoisting device, including: a crane hook 1, and further including: a first component; The first component includes a universal joint 201, which is hung on the crane hook 1 via a hanging ring. A connecting frame 202 is fixedly connected to the bottom of the universal joint 201. A damping buffer 203 is symmetrically fixedly connected to the bottom of the connecting frame 202. An auxiliary square cavity 204 is fixedly connected to the bottom of each of the damping buffers 203. An auxiliary plate 205 is fixedly connected to the bottom of the two auxiliary square cavities 204. An electrically controlled telescopic support rod 206 is fixedly connected to the four corners of the bottom surface of the auxiliary plate 205. A buffer pad 207 is hinged and fixed to the telescopic end of the electrically controlled telescopic support rod 206. An tilt sensor 208 is installed below the auxiliary plate 205.

[0026] in: The first component / adaptive leveling and anti-sway component can automatically adapt to the tilt posture during the high-altitude hoisting of photovoltaic modules and perform corresponding leveling corrections to effectively suppress left and right swaying and shaking during the hoisting process; at the same time, it has the ability to buffer and reduce shock absorption, weaken the impact and vibration caused by lifting, alignment and wind, keep the photovoltaic modules stable throughout the process, avoid collisions, twisting deformation and internal cracks, and adapt to complex high-altitude and windy hoisting conditions.

[0027] Universal joint 201, damping buffer 203, and buffer pad 207 constitute a swaying impact torque buffer group; electric telescopic support rod 206 and tilt sensor 208 constitute a hoisting leveling group.

[0028] The damping buffer 203 and the buffer pad 207 work together to absorb swaying, impact and swinging torque, and self-adaptively level throughout the process, suppressing left and right and front and back swings, avoiding tilting, bumping, twisting and hidden cracks when photovoltaic modules are hoisted at high altitudes, and adapting to complex working conditions such as wind at high altitudes and uneven supports.

[0029] The sliding frame 404 is adapted to slide within the internal square cavity of the auxiliary square cavity 204.

[0030] The tilt sensor 208 is used to detect the tilt angle of the photovoltaic panel or the lifting frame 301 during the hoisting process, and works with the electrically controlled telescopic support rod 206 to automatically fine-tune and level it; and through the universal joint 201, it can realize flexible reversal at multiple angles and eliminate hoisting torque.

[0031] A further embodiment: Please refer to Figures 1 to 5 As shown: A lifting frame 301 is provided below the auxiliary plate 205. The tilt sensor 208 is fixed to the side wall of the lifting frame 301. The side of the buffer pad 207 away from the electrically controlled telescopic support rod 206 is fixed to the upper surface of the lifting frame 301. A slotted base 302 is symmetrically fixed to the side wall of the lifting frame 301. Two symmetrical slotted bases 302 form a set of fixed anchor points. Flexible lifting straps 303 are inserted into the slots of the two slotted bases 302 in the set of fixed anchor points. A vacuum suction cup assembly 304 is symmetrically fixed to the lifting frame 301.

[0032] in: The second component / multi-point distributed hoisting component adopts a multi-point distributed force hoisting method, which can evenly distribute the overall load of the photovoltaic module, and the force distribution is balanced without generating local stress concentration; it can flexibly fit the photovoltaic panel for reliable adsorption, and the hoisting force is gentle without squeezing or damaging the panel surface and frame. It is suitable for the lifting load of photovoltaic modules of different specifications, and the hoisting force is stable, and the overall lifting is balanced and safe.

[0033] The slotted base 302 can be installed according to specific circumstances; its lifting points can be flexibly adjusted to accommodate flexible slings 303 of different sizes and specifications, facilitating the fixing of photovoltaic modules of different sizes.

[0034] The vacuum suction cup assembly 304 consists of a suction cup and a pipeline, which is connected to an external vacuum pump.

[0035] The vacuum suction cups in the vacuum suction cup assembly 304 can effectively adhere to the panel surface and perform flexible adsorption. Combined with the flexible slings 303, the load is evenly distributed, which can effectively avoid local deformation, crushing and damage to the photovoltaic panel caused by single-point force. The force is evenly distributed at the lifting points, so that the lifting force is not concentrated and the edges are not warped. This improves the overall lifting rigidity and stability requirements, and can smoothly lift and transport large-area photovoltaic modules.

[0036] A further embodiment: Please refer to Figures 2 to 4 , Figure 7 , Figure 8 As shown: The bottom surface of the hoisting frame 301 is symmetrically provided with a sliding groove, in which a positioning slider 401 is slidably connected. A cylindrical cavity is provided within the positioning slider 401, and a spring 402 is fixedly connected within this cavity. A pressure bar 403 is fixedly connected to the end of the spring 402 away from the fixed point, and the pressure bar 403 slides within the cylindrical cavity via the cylindrical body. A silicone plug is fixedly connected within the square cavity of the auxiliary square cavity 204, and a sliding frame 404 is slidably installed within this square cavity. 04. A limit baffle 405 is fixedly connected to the bottom. Electrically controlled telescopic devices 406 are symmetrically arranged on the upper surface of the auxiliary plate 205 through vertical plates. An insertion tube 408 is hinged to the front end of the electrically controlled telescopic device 406. Through holes 409 are equidistantly opened on the insertion tube 408. Insertion parts 410 are inserted into the through holes 409. An auxiliary tube is fixedly connected to the sliding frame 404. A guide tube 407 is fixedly connected to the bottom surface of the auxiliary tube. The insertion tube 408 is slidably adapted to the guide tube 407.

[0037] in: The third component / rapid adaptation positioning component can quickly and adaptively adapt to photovoltaic modules of different sizes and specifications, achieving rapid positioning, limit locking, and precise centering; it has elastic adaptive pressure and sliding adjustment capabilities, is quick to disassemble and adapt, and is not easy to shift or loosen after positioning. It can quickly complete the assembly and fixation of tooling and photovoltaic modules, improving the clamping efficiency and positioning accuracy before hoisting.

[0038] Spring 402 and pressure bar 403 can flexibly fit together to limit the position of photovoltaic modules / photovoltaic panels.

[0039] The positioning slider 401, spring 402, and pressing bar 403 constitute the limiting group A.

[0040] The sliding frame 404 and the limiting baffle 405 constitute the limiting group B.

[0041] Limiting group A and limiting group B can effectively limit the four sides of photovoltaic modules / photovoltaic panels.

[0042] A hole is provided on the guide tube 407; when the insert 410 is inserted into the hole and any through hole 409 on the insertion tube 408, the guide tube 407 and the insertion tube 408 are relatively fixed.

[0043] The guide tube 407, the insertion tube 408 and the insertion piece 410 work together to achieve quick insertion, positioning and locking, and the electrically controlled telescopic device 406 assists in precise alignment; it can quickly adapt to photovoltaic modules of different length and width specifications, automatically center and limit, prevent deviation and movement, ensure accurate installation and alignment, and quick disassembly and locking, without the need for repeated manual calibration, which greatly improves the efficiency and accuracy of high-altitude hoisting and positioning.

[0044] All of the above-mentioned electronic control components are electrically connected to the main controller of the device.

[0045] It should be noted that the above components are structurally nested and functionally interdependent. The third component (positioning) is a prerequisite for the operation of the first component (leveling): if the photovoltaic module is not centered and limited on the hoisting frame by the positioning slider 401 and the limiting baffle 405 of the third component, the center of gravity of the module will inevitably deviate from the hoisting center. Although the electrically controlled telescopic support rod 206 of the first component can adjust the tilt angle, it cannot correct the problem of "continuous overload on one side" caused by the center of gravity offset. This can lead to a sharp increase in leveling power consumption or even torsion deformation of the hoisting frame. Unlike "conventional universal joint leveling" technology, which assumes that the load center of gravity coincides with the hoisting point, the third component of this invention solves the problem of realizing this implicit premise, making dynamic leveling not only "theoretically feasible" but also "engineering reliable".

[0046] The second component (flexible distributed lifting) provides a stable load-bearing interface for the first component (damping buffer): the combination of the flexible lifting straps 303 and the vacuum suction cup assembly 304 allows the lifting frame 301 to form a multi-point balanced low-stress field at the initial stage of lifting, significantly improving the overall stiffness. This stable load-bearing interface allows the damping buffer 203 and the buffer pad 207 of the first component to focus on absorbing high-frequency wind vibrations and start-stop impacts, without having to simultaneously cope with the swaying or slippage of the component itself. Conversely, without the flexible constraint of the second component, the buffer structure of the first component would be saturated by low-frequency large-amplitude swaying, failing to perform its precise leveling function.

[0047] Therefore, the relationship between the three components is as follows: the third component provides the "centering reference" → the second component provides the "stable load-bearing capacity" → the first component provides the "precise leveling capacity". Each component is indispensable and forms a complete "positioning-load-leveling" technical closed loop.

[0048] The working principle of all the content in the above embodiments is as follows: Lifting preparation and photovoltaic module positioning: Place the photovoltaic module under the lifting frame 301, push the positioning slider 401 to slide along the bottom groove of the lifting frame 301, and adjust it to a position suitable for the length of the photovoltaic module; the spring 402 inside the positioning slider 401 pushes the pressure bar 403 to move and extend, elastically pressing against the side of the photovoltaic module, completing the initial limiting of limit group A. Start the electrically controlled telescopic device 406, push the insertion tube 408 to slide in the guide tube 407, drive the sliding frame 404 to move along the square cavity inside the auxiliary square cavity 204, so that the limiting baffle 405 fits against the other side of the photovoltaic module, completing the limiting of limit group B; and finally insert the insertion piece 410 into the guide tube 407 and the corresponding through hole 409 to lock the limiting distance, realizing the rapid centering and positioning of the photovoltaic module.

[0049] Photovoltaic module fixing and stress preparation: Start the external vacuum pump to make the vacuum suction cup assembly 304 flexibly attach to the back of the photovoltaic module and form a negative pressure adsorption; pass the flexible sling 303 through the slot of the slot base 302 and bind it to the frame of the photovoltaic module to form a multi-point distributed stress fixing structure, and complete the clamping before hoisting.

[0050] Lifting and Automatic Leveling: The crane hook 1 is attached to the top ring of the universal joint 201, and the crane is started to lift. During the lifting process, the tilt sensor 208 collects the tilt angle data of the lifting frame 301 and transmits it to the controller. The controller drives the electric telescopic support rods 206 at the four corners to make slight extension and retraction adjustments based on the data. The buffer pad 207 drives the lifting frame 301 to dynamically correct the tilt deviation, keep the photovoltaic module horizontal throughout the process, and complete the automatic leveling of the lifting and leveling group.

[0051] Transfer buffering and torque dissipation: During the transfer process, the universal joint 201 rotates freely to dissipate the hoisting torque; the damping buffer 203 under the connecting frame 202, together with the buffer pad 207, absorbs the swaying potential energy and impact load generated by wind disturbance, hoisting and starting and stopping, suppresses the multi-dimensional swaying of photovoltaic modules, and realizes swaying impact torque buffering, shock absorption and anti-swaying.

[0052] High-altitude alignment and unloading: After hoisting to the installation position, the device remains horizontal and stable; during unloading, the buffer pad 207 and damping buffer 203 further dissipate the impact of contact to prevent damage to the components; the vacuum pump is turned off to release the vacuum suction cup group 304, the flexible sling 303 is released, the insertion piece 410 is pulled out and the limiting structure is retracted, completing the entire process of distributed hoisting of photovoltaic modules.
