Description

Technical Field

[0001] This invention relates to the field of lifting equipment technology, specifically to a split-type load-bearing safety lifting equipment for high-altitude construction. Background Technology

[0002] In high-altitude construction scenarios involving building exterior walls, specialized hoisting equipment is required to suspend and support workers and auxiliary equipment. Simultaneously, protective structures must be in place to mitigate the risks of falling objects and dust leaks, ensuring the safety and stability of high-altitude suspended operations. Currently, most existing high-altitude construction hoisting equipment uses a single, integrated load-bearing structure, with equipment and personnel sharing the same suspension structure. This concentrated load distribution easily leads to problems such as stress imbalance, overall equipment swaying, and poor suspension stability, resulting in significant safety hazards during high-altitude operations.

[0003] Meanwhile, the protective frames of traditional hoisting equipment are mostly fixed integral structures. The frame dimensions cannot be flexibly extended, folded, or adjusted, resulting in extremely poor adaptability. They are difficult to match with exterior wall construction areas of different widths and heights, as well as confined high-altitude work spaces. The equipment has low versatility and is inconvenient to transport and store. In addition, the bottom sealing and protective structure of the hoisting equipment often uses rigid integral baffles, which are cumbersome to assemble and disassemble, prone to loosening and shifting after long-term use, and cannot adapt to the slight concavity and convexity of the exterior wall surface. This can easily create assembly gaps, leading to insufficient protective sealing and problems such as construction debris falling and dust leakage. It cannot meet the standardized and high-safety requirements of high-altitude hoisting construction.

[0004] In summary, existing high-altitude construction hoisting equipment has technical defects such as unreasonable load-bearing methods, poor suspension stability, weak frame adaptability, and insufficient stability and sealing of baffle assembly, which urgently need to be optimized and improved. Summary of the Invention

[0005] The purpose of this invention is to provide a high-altitude construction split-type load-bearing safety hoisting device to solve the technical problems of existing traditional hoisting devices, such as concentrated load-bearing of personnel and equipment, poor suspension stability, poor adaptability of fixed protective frame size, easy loosening of baffles, and poor sealing effect against the wall.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution: A high-altitude construction split-type load-bearing safety hoisting device includes a suspension component, a deformable aluminum alloy frame, a protective net, and a PVC baffle component. The suspension component includes equipment suspension ropes and personnel suspension ropes, enabling independent load-bearing of equipment and personnel. The deformable aluminum alloy frame is a rectangular three-dimensional frame structure, formed by splicing and fixing four horizontal telescopic rods, four vertical folding rods, and four vertical telescopic uprights. The horizontal telescopic rods, the vertical folding rods, and the vertical telescopic uprights cooperate to form a frame body that can be extended, retracted, and folded as a whole. The protective net is fixedly laid on the outer wall of the deformable aluminum alloy frame. The PVC baffle component is detachably assembled to the bottom edge of the deformable aluminum alloy frame. The inner side of the PVC baffle component is equipped with an elastic buffer structure. The elastic buffer structure can maintain a large inner diameter for assembly without compression, and can shrink in diameter and lock in position under the compression of adjacent baffles. It also has the ability to elastically deform and self-adjust and reposition itself.

[0007] In a preferred embodiment, the four horizontal telescopic rods and the four vertical telescopic poles are all three-section sleeve telescopic structures. The three-section sleeve telescopic structure includes a middle rod and two side rods. The two side rods are respectively inserted into the two ends of the middle rod and can slide and extend along the length of the middle rod.

[0008] In a preferred embodiment, the four longitudinal folding rods are respectively assembled on the longitudinal side of the deformable aluminum alloy frame. The longitudinal folding rods are aluminum alloy hinged folding structures, and the two ends of the longitudinal folding rods are respectively hinged and fixed to the corresponding transverse telescopic rods.

[0009] In a preferred embodiment, the protective net is a woven mesh made of polyester fiber, and the protective net is fixed to all the outer walls of the deformable aluminum alloy frame except for the top end face and the inner end face.

[0010] In a preferred embodiment, the PVC baffle assembly includes several groups of evenly arranged PVC baffle units, each PVC baffle unit being integrally formed with an arc-shaped retaining plate, the arc-shaped retaining plate having a retaining notch facing the deformable aluminum alloy frame member.

[0011] In a preferred embodiment, the arc-shaped clamping plate is an integrally molded structure made of elastic material. The inner diameter of the arc-shaped clamping plate is adapted to the outer diameter of the bottom edge member of the deformable aluminum alloy frame. The diameter of the notch is smaller than the outer diameter of the bottom edge member of the deformable aluminum alloy frame. The bottom edge member of the deformable aluminum alloy frame can be inserted into or removed from the arc-shaped clamping plate through the notch, so that the arc-shaped clamping plate elastically hugs the outside of the bottom edge member, thereby realizing the detachable assembly of the PVC baffle unit.

[0012] In a preferred embodiment, the PVC baffle unit is fixedly connected to the arc-shaped card plate, the PVC baffle unit is tilted upward relative to the arc-shaped card plate, and a plurality of the PVC baffle units are evenly arranged along the bottom edge of the deformable aluminum alloy frame and spliced ​​together to form a continuous enclosure structure.

[0013] In a preferred embodiment, an elastic buffer layer is fixedly attached to the inner wall of the arc-shaped card plate. The left and right sides of the elastic buffer layer are integrally formed with outwardly protruding extrusion flanges. The extrusion flanges are set to protrude from the arc surface of the elastic buffer layer. The extrusion flanges on adjacent PVC baffle units abut against each other. The extrusion flanges can be squeezed to undergo elastic deformation and embed into the gap between the arc-shaped card plate and the outer wall of the rod.

[0014] In a preferred embodiment, the end of the extrusion flange is provided with an arc-shaped pressure guiding slope, which is oriented toward the adjacent extrusion flange, and the two opposing arc-shaped pressure guiding slopes slide and fit together.

[0015] In a preferred embodiment, the arc curvature of the arc-shaped pressure guide slope gradually decreases from the end of the extrusion flange to the root, and two adjacent arc-shaped pressure guide slopes that cooperate with each other have a symmetrical fitting structure.

[0016] Compared with existing technologies, this invention uses a multi-dimensional deformable aluminum alloy frame as the load-bearing base of the lifting device. Through the cooperation of horizontal and vertical telescopic rods and longitudinal folding rods, the frame size is flexibly adjustable and the whole device can be folded and stored. This effectively solves the problems of fixed frame specifications, limited applicable scenarios, and large space occupation during transportation and storage of traditional lifting devices. It can adapt to different exterior wall sizes and different narrow high-altitude operation scenarios, and the lifting device has strong universality and adaptability. In addition, this invention uses a split and detachable PVC baffle assembly with a built-in elastic buffer locking structure. It can be easily and quickly assembled in a pressure-free state. When adjacent baffles are squeezed, they automatically shrink in diameter and lock in position, completely solving the problems of cumbersome assembly and easy loosening and displacement of traditional lifting device baffles. The elastic structure can adapt to the slight concave and convex deformation of the wall surface, continuously and tightly fit the wall surface, and automatically reset, eliminating assembly gaps and effectively improving the protective sealing of the lifting device during operation, eliminating the risk of falling objects and dust leakage.

Detailed Implementation

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

[0025] This specific embodiment is merely an explanation of the present invention and is not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.

[0026] like Figures 1 to 6 As shown, this embodiment discloses a high-altitude construction split-type load-bearing safety hoisting device, belonging to the technical field of B66C lifting and hoisting devices. It is specifically applied to the scenario of split-type hoisting and load-bearing of personnel and equipment and safety protection in high-altitude exterior wall construction operations. It can effectively improve the technical problems of traditional high-altitude hoisting devices, such as load imbalance, poor suspension stability, weak frame adaptability, and poor baffle sealing protection. The overall hoisting load is stable, the structure can be flexibly deformed and adjusted, it is easy to assemble and disassemble, and has excellent protective airtightness.

[0027] In this embodiment, the lifting device is composed of a suspension assembly, a deformable aluminum alloy frame, a protective net 6, and a PVC baffle assembly. The suspension assembly specifically includes two independent suspension load-bearing structures: equipment suspension rope 1 and personnel suspension rope 2. These are the core load-bearing components of the lifting device, enabling separate load-bearing of equipment and personnel. The deformable aluminum alloy frame adopts a rectangular three-dimensional frame structure, mainly composed of four horizontal telescopic rods 3, four vertical folding rods 4, and four vertical telescopic uprights 5, which are spliced ​​and fixed together. Based on the structural cooperation between the horizontal telescopic rods 3, the vertical folding rods 4, and the vertical telescopic uprights 5, the overall frame can achieve multi-dimensional deformation adjustment through telescoping and folding, possessing flexible deformation and adaptability, serving as the load-bearing support base of the lifting device. The protective net 6 is fixedly laid on the outer side wall of the deformable aluminum alloy frame, forming an overall outer protective structure. The PVC baffle assembly is detachably mounted at the bottom edge of the deformable aluminum alloy frame. As the core sealing and protective structure at the bottom, the PVC baffle assembly is equipped with a dedicated elastic buffer structure. This elastic buffer structure has adaptive structural adjustment characteristics. Under natural conditions without external pressure, it can maintain a large clamping inner diameter, which facilitates the quick assembly of parts. Under the mutual pressure of adjacent baffle structures, it can achieve diameter reduction and locking positioning. At the same time, the whole has the ability to adapt to elastic deformation and adjust itself and fit under pressure, which can adapt to the slight deformation of the wall and maintain a continuous sealing state.

[0028] This lifting device features a split-type suspension structure as its core innovation, overturning the traditional integrated suspension and load-bearing mode. It separates equipment load-bearing from personnel load-bearing, solving the safety problems of stress imbalance and device swaying during high-altitude suspension operations. Equipped with a multi-dimensional deformable aluminum alloy load-bearing frame, its size can be flexibly adjusted and folded for storage according to the construction scenario, greatly improving the device's versatility and portability. Combined with a detachable elastic locking PVC baffle and a full-coverage protective net, it constructs a comprehensive sealed protection system, ensuring stable suspension and load-bearing while solving the problems of falling objects and dust leakage during high-altitude construction. It is suitable for various high-altitude suspension construction conditions on building exterior walls.

[0029] In this embodiment, the four horizontal telescopic rods 3 and the four vertical telescopic poles 5 all adopt a three-section sleeve telescopic structure design. The specific structure includes a middle rod and two side rods. The two side rods are respectively inserted into the two ends of the middle rod, and the side rods can achieve stable sliding extension and retraction along the length direction of the middle rod, thereby realizing flexible adjustment of the overall length of the rods.

[0030] The horizontal telescopic member 3 and the vertical telescopic pole 5 adopt a standardized three-section sleeve nested telescopic structure. Utilizing the sliding plug-in connection between the side poles and the middle poles, and relying on the coaxial limiting characteristics of the sleeve structure, the side poles can only slide linearly back and forth along their length, achieving stepless and precise adjustment of the pole length. This adapts to the horizontal width and vertical height requirements of different construction surfaces. The sleeve nesting mechanism provides excellent structural constraint, maintaining the coaxiality of the poles throughout the telescopic adjustment process and avoiding problems such as offset, skewness, and jamming. Once adjusted, the multiple layers of poles are tightly nested, resulting in a large contact area and significantly improved structural rigidity and bending strength. This ensures stable support for the overall frame, protective net 6, and baffle assembly, as well as external operational forces, guaranteeing the structural stability of the lifting device after its overall formation. When facing construction areas of different sizes, the telescopic adjustment can quickly adapt to the working conditions without the need to change different specifications of lifting equipment, thus reducing the investment cost of construction equipment; after the operation is completed, the poles can be retracted to shorten the overall pole length, greatly reducing the overall space occupied by the lifting equipment, which greatly facilitates the transfer, handling and storage of equipment, and effectively improves the reusability of the lifting equipment and the convenience of construction.

[0031] In this embodiment, four longitudinal folding rods 4 are respectively assembled and arranged on the longitudinal side of the deformable aluminum alloy frame. The longitudinal folding rods 4 adopt an aluminum alloy hinged folding structure. The two ends of the longitudinal folding rods 4 are respectively hinged and fixed to the corresponding transverse telescopic rods 3 to form a rotatable movable connection structure.

[0032] The longitudinal folding member 4 is rotatably connected to the transverse telescopic member 3 via hinged nodes at both ends. Utilizing the rotational freedom of the hinged structure, the longitudinal sides of the frame can be flexibly folded and unfolded, forming a multi-dimensional linkage deformation system with the transverse telescopic member 3 and the vertical telescopic upright 5, further enriching the deformation adjustment capability of the lifting frame. When the lifting equipment is being transported, stored, or adapted to construction scenarios in extremely small spaces, the folding member 4 can be rotated inward to shrink the longitudinal span of the frame, reducing the overall volume of the lifting equipment and avoiding the drawbacks of traditional fixed lifting equipment being bulky and inconvenient to transport. During normal high-altitude construction operations, the folding member 4 can be fully unfolded and locked to reset and form a regular rectangular three-dimensional frame structure, ensuring the overall support integrity and stress balance of the lifting equipment. The aluminum alloy folding rod is lightweight, high-strength, and has strong resistance to deformation. The hinged connection nodes rotate smoothly and have reliable limit. It will not loosen, deform, or jam after repeated folding and unfolding over a long period of time, effectively ensuring the structural integrity and load-bearing stability of the lifting equipment for long-term use, and is suitable for various complex and restricted high-altitude construction and hanging environments.

[0033] In this embodiment, the protective net 6 is made of polyester fiber woven mesh structure. The protective net 6 is fixed to the outer wall of the deformable aluminum alloy frame, and avoids the top end face and inner end face, only covering the remaining outer area of ​​the frame.

[0034] Polyester fiber possesses excellent physical and chemical properties, including high tensile strength, wear resistance, aging resistance, corrosion resistance, and toughness. The densely woven mesh structure is lightweight and moderately permeable, providing strong impact and tear resistance without excessively increasing the load on the lifting equipment. It effectively resists impacts and pulls from debris such as gravel, tools, and building material fragments during high-altitude operations, preventing mesh damage and failure. The protective netting employs a differentiated, full-coverage installation method, avoiding the inner end face that adheres to the building's exterior wall and the top suspension connection end face. This ensures it does not obstruct the installation and positioning of the lifting equipment against the exterior wall, nor interfere with the assembly and fixation of the suspension components. Simultaneously, it provides comprehensive, seamless protection for the outer, bottom, front, and rear sides of the frame, effectively reducing the problem of debris falling outwards and dust spillage. This material can withstand harsh outdoor environments such as sun exposure and wind and rain erosion for extended periods, is not prone to aging, embrittlement, damage, or deformation, and has a longer service life. It can continuously and stably maintain the closed protective state of the lifting equipment operation area, standardizing high-altitude suspended construction protection standards and ensuring the safety of the surrounding environment and personnel and equipment below.

[0035] In this embodiment, the PVC baffle assembly consists of several groups of evenly arranged PVC baffle units 7. Each group of PVC baffle units 7 is integrally formed with an arc-shaped clamping plate 8. The arc-shaped clamping plate 8 has a clamping notch 9 facing the deformable aluminum alloy frame member, which is used to realize the alignment and clamping assembly of the baffle unit 7.

[0036] The PVC baffle assembly adopts a multi-unit, segmented modular structure, replacing the traditional integral baffle structure. This design avoids the drawbacks of fixed dimensions, cumbersome assembly and disassembly, and the need for complete replacement of the entire assembly in case of partial damage. It allows for independent assembly and replacement of individual baffle units 7, significantly reducing the later maintenance costs and operational difficulties of the lifting equipment. Each baffle unit 7 is integrally injection molded with the arc-shaped clamping plate 8, resulting in strong structural integrity, high molding precision, and no assembly gaps or loosening risks. Utilizing the notches 9 on the arc-shaped clamping plate 8 facing the frame members, it can be directly aligned and snapped into place with the bottom frame members, ensuring stable assembly and positioning, and simple and quick operation. Multiple sets of baffle units 7 are evenly and regularly arranged along the bottom edge of the frame, and are tightly spliced ​​together to continuously seal the strip gap between the bottom of the frame and the building's exterior wall, forming a complete closed-loop bottom enclosure structure. This effectively prevents construction debris, dust, and airflow from leaking out from the bottom gap, compensates for the blind spot at the bottom of the protective net 6, and improves the overall three-dimensional closed protection system of the hoisting equipment, thereby comprehensively enhancing the protective airtightness of high-altitude suspended construction.

[0037] Based on the above structure, the arc-shaped clamping plate 8 in this embodiment adopts an integral molding structure of elastic material. The inner diameter of the arc-shaped clamping plate 8 is compatible with the outer diameter of the bottom edge member of the deformable aluminum alloy frame. The diameter of the notch 9 is smaller than the outer diameter of the bottom member of the frame. The bottom edge member of the frame can be inserted or removed through the notch 9, so that the arc-shaped clamping plate 8 can be elastically held on the outside of the bottom edge member, realizing the detachable assembly and fixation of the PVC baffle unit 7.

[0038] The arc-shaped clamping plate 8 is integrally molded from a highly elastic and flexible material, possessing excellent reversible elastic deformation capability. Combined with the dimensional structural design where the diameter of the clamping notch 9 is smaller than the outer diameter of the rod, and the inner diameter of the clamping plate precisely matches the outer diameter of the rod, a flexible interference fit assembly structure is formed. During assembly, external force can be used to pry open the clamping notch 9 outward, and the clamping plate's own elastic deformation can expand the notch opening, allowing the bottom rod of the frame to smoothly embed into the clamping plate 8. After the rod is fully in place, the external force is removed, and the clamping plate 8 automatically retracts and resets itself based on its own elastic restoring force, tightly fitting and holding the outer wall of the rod, achieving a self-locking assembly and fixation without fasteners. During disassembly, simply pry the clamping plate 8 open the clamping notch 9 again to remove the baffle unit 7 from the rod. The disassembly and assembly process is simple and efficient, allowing for quick completion of baffle installation, disassembly, position fine-tuning, and spacing calibration. The flexible clamping assembly method avoids hard compression and wear, and will not damage the frame members and baffle structure. After assembly, there is no loosening or displacement, and the positioning stability is excellent. It can adapt to the long-term repeated disassembly, relocation and adjustment operation requirements of the lifting equipment on the construction site, and significantly improves the ease of assembly, adjustment flexibility and reusability of the lifting equipment.

[0039] In this embodiment, the PVC baffle unit 7 and the arc-shaped card plate 8 are fixedly connected. The PVC baffle unit 7 is arranged in an upward tilting and upturned shape relative to the arc-shaped card plate 8. Several PVC baffle units 7 are evenly arranged along the bottom edge of the deformable aluminum alloy frame and spliced ​​together to form a continuous bottom enclosure structure.

[0040] The PVC baffle unit 7 and the curved clamping plate 8 are fixed as a rigid, integrated structure with no relative displacement. This results in high overall structural strength and excellent stress stability, effectively resisting the impact of construction airflow and debris. The baffle unit 7's upward tilt relative to the curved clamping plate 8 is designed to naturally align with the building's exterior wall, perfectly meeting the protection and sealing requirements of the vertical facade. It actively conforms to the wall's contour, minimizing the initial gap between the baffle and the wall. Multiple baffle units 7 are evenly spaced along the bottom of the frame, with their ends tightly joined together, effectively eliminating gaps between individual baffles and forming a continuous, closed enclosure structure without breaks or blind spots. The tilted, upward-tilted structure not only precisely seals bottom gaps but also creates a positive shielding and guiding effect, preventing dust and debris from spreading downwards and outwards, further strengthening the bottom sealing protection of the hoisting equipment. This continuously maintains a closed and clean state in the suspended work area, eliminating the safety hazards and dust pollution problems associated with high-altitude construction debris leakage.

[0041] Furthermore, in this embodiment, an elastic buffer layer 10 is fixedly attached to the inner wall of the arc-shaped card plate 8. The left and right sides of the elastic buffer layer 10 are integrally formed with outwardly protruding extrusion flanges 11. The extrusion flanges 11 protrude from the arc surface of the elastic buffer layer 10. The extrusion flanges 11 on adjacent PVC baffle units 7 abut against each other. The extrusion flanges 11 can undergo elastic deformation under external extrusion and embed into the gap between the arc-shaped card plate 8 and the outer wall of the rod.

[0042] The elastic buffer layer 10 is tightly fitted and fixed to the inner wall of the arc-shaped clamping plate 8, replacing the traditional rigid clamping plate structure that directly contacts the rod. This effectively avoids friction, wear, extrusion deformation, and abnormal noise caused by rigid contact between metal and hard plastic, providing effective protection for the lifting frame rods and the clamping plate 8 structure. The integrally formed protruding extrusion flanges 11 on both sides of the buffer layer constitute a dedicated extrusion fit structure between adjacent baffle units 7, achieving precise alignment and pressure through differentiated protrusion structures. When a single baffle unit 7 is assembled independently, adjacent baffles do not exert extrusion, and the extrusion flanges 11 are in a naturally extended state. The elastic buffer layer 10 maintains a large clamping inner diameter, with no assembly interference resistance, greatly reducing the difficulty of clamping a single baffle. When all baffle units 7 are assembled and arranged in sequence, the extrusion flanges 11 of adjacent baffles press against each other. The flanges undergo controllable elastic deformation under lateral extrusion force, gradually squeezing into the tiny gap between the arc-shaped clamping plate 8 and the outer wall of the rod. The deformation squeezing action can passively reduce the effective clamping inner diameter of the clamping plate 8, so that the buffer layer fully fits the outer wall of the clamping rod, and realizes the synchronous self-locking position of multiple baffle units 7. This improves the problems of loosening, shaking and angle deviation after the baffle of the traditional lifting device is assembled. At the same time, the elastic buffer layer 10 reserves sufficient elastic deformation margin, which provides core structural support for the subsequent adaptive fitting of the baffle to the wall deformation and force buffering reset.

[0043] Based on the structure of the elastic buffer layer 10 and the extrusion flange 11, the end of the extrusion flange 11 is provided with an arc-shaped pressure guiding slope 12. The arc-shaped pressure guiding slope 12 is arranged in the direction of the adjacent extrusion flange 11, and the two arc-shaped pressure guiding slopes 12 arranged opposite to each other can achieve sliding fit.

[0044] The opposing arc-shaped pressure-guiding slopes 12 at the ends of the extrusion flange 11 form an inclined guide sliding fit structure, overcoming the shortcomings of traditional straight-face end rigid alignment and difficult positioning. During the sequential arrangement and assembly of multiple baffle units 7, the arc-shaped slopes of adjacent flanges can slide against each other, utilizing the guiding characteristics of the arc-shaped surfaces to automatically guide the flanges on both sides to precise alignment and smooth fit, effectively avoiding problems such as end misalignment, rigid clamping, and assembly jamming, significantly improving the smoothness and alignment accuracy of multi-baffle assembly. Simultaneously, the opposing arc-shaped pressure-guiding slopes 12 can evenly decompose the horizontal extrusion force generated by the baffle arrangement into a radially inward locking component, allowing the extrusion force to act evenly and gently on the contact surface between the elastic buffer layer 10 and the rod, avoiding unilateral locking and local loosening caused by local stress concentration. All baffle units 7 are subjected to uniform force and locked synchronously. After assembly, the overall layout is neat and uniform with high angle consistency. Structurally, it ensures the overall airtightness of the multi-section baffle splicing and effectively improves the alignment effect and locking stability of the baffle assembly of the lifting device.

[0045] In a further optimized embodiment, the arc curvature of the mutually cooperating arc-shaped pressure guiding slope 12 gradually decreases from the end of the extrusion flange 11 to the root, and the two adjacent mutually cooperating arc-shaped pressure guiding slopes 12 are symmetrically adapted structures, so that the slope structures on both sides match each other.

[0046] The interlocking arc-shaped pressure-guiding slope 12 adopts a completely symmetrical structure, ensuring that the extrusion force and sliding stroke of adjacent flanges are completely consistent, reducing the problems of uneven force and asymmetrical deformation on one side. The slope adopts a gradually decreasing curvature structure with a large curvature at the end and a gradually decreasing curvature at the root, which is adapted to the force and deformation law of the entire process of baffle assembly and extrusion, forming a segmented and precise fit effect. In the initial approach stage of the baffles, the large curvature arc surface at the end has a wide contact range and strong guiding and containment, which can quickly achieve large-scale alignment and reduce the difficulty of initial assembly alignment; in the later locking and bonding stage, the small curvature arc surface at the root has higher bonding accuracy and more stable force, which can achieve precise limiting and stable bonding of flange deformation. The gradual curvature structure allows the flange to undergo gradual and uniform deformation from the end to the root, avoiding problems such as local stress concentration, flange plastic deformation, or extrusion failure caused by sudden compression. This effectively improves the smoothness, stability, and accuracy of the compression fit between adjacent baffles, ultimately ensuring that all baffle units have a uniform locking angle, are neatly arranged, and have uniform clamping force. Long-term use is less prone to loosening, displacement, or widening of gaps, significantly improving the reliability of the lifting device in long-term use.

[0047] In this embodiment, multiple micro-guide ribs 13 are evenly distributed on the slope of the arc-shaped pressure-guiding slope 12. The micro-guide ribs 13 are distributed along the curvature extension direction of the arc-shaped pressure-guiding slope 12, and the micro-guide ribs 13 on adjacent arc-shaped pressure-guiding slopes 12 can be aligned and slide together.

[0048] Multiple micro-guide ribs 13 arranged along the arc direction on the gradually curvature arc-shaped pressure-guiding slope 12 optimize the traditional complete surface contact sliding into an ordered line contact alignment sliding structure. This significantly reduces the contact area between adjacent slopes from the perspective of friction, effectively reducing sliding friction resistance and improving the problems of jamming, excessive resistance, and difficult assembly when sliding on large contact surfaces. This makes the alignment, pressing, and locking of multiple baffles smoother and easier. At the same time, the mutually aligned rib structure can form a lateral limiting constraint, restricting the lateral misalignment of adjacent pressing flanges 11. During assembly pressing and subsequent lifting operations, it ensures that the flanges are accurately aligned and centered under force, further improving the regularity and consistency of the overall arrangement of multiple baffles. The guiding and limiting function of the ribs can evenly disperse the frictional stress on the slope, reduce large-area wear, scratches and deformation of the slope, effectively protect the structural accuracy of the arc-shaped pressure guide slope 12, delay structural aging and wear, greatly improve the service life and long-term positioning accuracy of the baffle locking structure, and continuously ensure the sealing effect of the baffle of the lifting device.

[0049] In the suspension structure of this embodiment, the bottom end of the equipment suspension rope 1 is fixedly connected to the top four corners of the deformable aluminum alloy frame. It is used to suspend and bear the overall weight and working load of the deformable aluminum alloy frame, the protective net 6 and the PVC baffle assembly. The personnel suspension rope 2 is set on the side of the equipment suspension rope 1 and is used to suspend and bear the workers separately, realizing the separate suspension and bearing of the equipment and the workers. It is the core split bearing structure of the lifting device.

[0050] The equipment suspension rope 1 adopts a suspension structure with four symmetrical fixation points at the top of the frame. This four-point force distribution evenly distributes the overall self-weight load and external forces of the lifting equipment, ensuring uniform stress distribution and a stable center of gravity. This reduces problems such as frame tilting, torsion, and significant swaying that are common with single-point or two-point suspensions. It can stably support the entire equipment structure, including the aluminum alloy frame, protective netting 6, and PVC baffle components, ensuring overall load-bearing stability under suspension. The personnel suspension rope 2 is independently arranged beside the equipment suspension rope 1, completely separated from the equipment suspension system. This forms a dual independent load-bearing system for both equipment and personnel loads, completely isolating the mutual interference between equipment load changes and personnel movement during operation. This avoids safety hazards such as suspension imbalance and increased swaying caused by load superposition and force coupling. This dual-rope, split-type suspension load-bearing structure fundamentally avoids the risks of overload, imbalance, and falls in high-altitude suspended operations, significantly improving the suspension stability, operational safety, and construction reliability of the lifting equipment, making it suitable for various high-altitude, long-term suspended operation scenarios.

[0051] In this embodiment, each telescopic and folding structure is equipped with a locking component, such as abutting or locking bolts, to stabilize the structure after deformation and ensure the structural stability and load-bearing safety of the lifting device after adjustment.
