Description

Technical Field

[0001] This invention relates to the field of construction equipment technology, and more specifically, to a novel edge protection pole. Background Technology

[0002] This invention belongs to the field of construction safety protection technology and is mainly applied to safety protection operations at the edges of buildings, such as open spaces, foundation pits, and areas with significant floor height differences. According to construction safety regulations, areas with a floor height difference exceeding 2 meters must have a double-layer protective structure. The upper layer must have a minimum height of 1.2 meters, and the lower layer a minimum height of 0.6 meters, to prevent falls from heights. Currently, the mainstream edge protection methods on construction sites are divided into two categories: steel pipe fastener-type protection and standardized rigid guardrails. Steel pipe installation requires manual cutting and extension of steel pipes to fit different opening sizes. The cut steel pipes have poor versatility and low turnover rate, and manual installation is prone to problems such as insufficient protection height and improper installation. Standardized rigid guardrails have fixed overall dimensions and can only fit standard rectangular openings. They cannot be properly installed on irregular, zigzag, or curved edges, creating blind spots. Installation and dismantling operations typically require two workers, resulting in low construction efficiency.

[0003] Among existing technologies, the invention patent "A Retractable Edge Protection Fence" (authorization announcement number CN224413215U, application number CN202522010104.7) is the closest to this solution. This prior art discloses a standardized protective structure consisting of two posts, a bidirectional screw telescopic mechanism, and a rigid metal protective plate. The posts have an integrally formed fixed base at the bottom, and the protective width is adjusted by the screw driving the nested metal plate to extend and retract. After adjustment, the protective plate is locked in place by tightening bolts. Although this prior art achieves width adjustment within a certain range, it still has insurmountable technical defects in practical engineering applications. The specific technical problems are as follows: The entire protective structure is made of rigid metal plates and sleeves. Its extension range is rigidly limited by the length of the sleeves and threaded rods, making it only suitable for regular rectangular openings. It cannot accommodate the numerous curved, zigzag, and irregularly shaped openings with edges present on construction sites. The protective structure cannot conform to the edge contours, resulting in gaps in protection and insufficient safety integrity. The overall structure is a single rigid frame with significant component weight. At least two workers are required to operate the transport, installation, and dismantling processes; a single person cannot independently complete the installation and dismantling, leading to high labor costs and low construction efficiency. The height of the protective layer... Relying on manual on-site adjustment of screw rods and bolts is highly dependent on the skill level of construction personnel, and it is easy for the double-layer protection height to fail to meet the standard benchmarks, making it difficult to uniformly control the protection standards; the metal telescopic plates and screw rod locking structure components are numerous, and during long-term storage and transportation, parts are prone to loss, screw rod corrosion and jamming, etc. The overall components occupy a large storage space and have a low cross-project turnover and reuse rate; the protective plate is fixed to the column by a single-point bolt locking, which is prone to slippage and loosening when subjected to external pulling or impact, resulting in poor overall protection structure stability and safety hazards. Summary of the Invention

[0004] The purpose of this invention is to provide a new type of edge protection pole to solve the problems mentioned in the background art, which are that the main body of the protection is made of rigid metal plates and sleeve structures, the extension stroke is rigidly limited by the length of the sleeve and screw, and it can only be used for regular rectangular openings. It cannot be used for the many curved, broken, and irregular edge openings that exist on the construction site. The protection structure cannot fit the edge contour, there are blank areas in the protection, and the safety protection integrity is insufficient.

[0005] To achieve the above objectives, the present invention provides a novel edge protection pole, comprising a pole body and a self-winding rope assembly. The pole body serves as a vertical support carrier for supporting the self-winding rope assembly. The self-winding rope assembly is assembled on the outside of the pole body and has a built-in locking mechanism. The output end of the self-winding rope assembly is equipped with a detachable fixing buckle. The self-winding rope assembly internally houses a retractable flexible protective rope. After the flexible protective rope extends, its length is limited by the locking mechanism. The fixing buckle is used to detachably engage with another novel edge protection pole. Multiple pole bodies combined with flexible protective ropes together construct an edge protection barrier.

[0006] This setup consists of a main pole and a self-winding rope assembly with a built-in flexible protective rope to form a basic protection unit. The flexible rope can freely extend and retract to adapt to openings of different widths, and can conform to irregular edge contours to eliminate blind spots. The entire set of components can be quickly disassembled and recycled, greatly improving the efficiency of component turnover and reuse. At the same time, the locking mechanism locks the rope extension length to ensure the stability and reliability of the edge protection structure.

[0007] As a preferred embodiment of the present invention, a support plate is installed at the bottom end of the main body of the pole, and the support plate is fixed to the base by bolts.

[0008] This setup provides stable support to the bottom of the upright by connecting the support plate to the base with bolts, increasing the contact area between the upright and the construction surface, effectively resisting the horizontal force generated by the pull of the flexible rope, preventing the upright from tilting or shifting, and the bolted connection structure facilitates disassembly and relocation, adapting to different construction surface installation conditions.

[0009] As a preferred embodiment of the present invention, the self-winding rope assembly includes an annular sleeve, the flexible protective rope is wound and housed inside the annular sleeve, a rope outlet is provided on one side of the annular sleeve, the flexible protective rope extends out from the rope outlet, and a plurality of fixing slots are installed on the outer wall of the annular sleeve, and the fixing buckle of the flexible protective rope end of one pole body engages with the fixing slot of another pole body.

[0010] This setup relies on a ring sleeve to store the flexible protective rope, while the rope outlet provides a passage for rope extension and retraction. Multiple sets of fixing slots on the outer wall engage with fixing buckles, allowing for flexible adjustment of the rope connection points between two poles. It is suitable for various opening widths, and the snap-fit ​​connection eliminates the need for additional fasteners, simplifying the on-site installation process.

[0011] As a preferred embodiment of the present invention, the fixing slots are arranged in a ring at equal intervals on the outer wall of the annular sleeve.

[0012] This feature, with its equally spaced, circularly arranged fixing slots, provides multiple locking points in various directions and positions. During construction, the locking positions can be freely selected according to the direction of the edge and the width of the opening, adapting to irregular edge layouts such as zigzag and arc shapes. The stress distribution is uniform, avoiding localized stress concentration caused by single-point locking.

[0013] As a preferred embodiment of the present invention, the locking mechanism adopts a threaded rod structure, the locking mechanism is screwed and fixed on the annular sleeve, and the end of the locking mechanism clamps and fixes the flexible protective rope inside the annular sleeve.

[0014] This threaded rod spinning locking structure allows for adjustment of the clamping force through screwing, continuously pressing the flexible protective rope to prevent it from retracting and sliding. The locking operation is simple and intuitive, and the locking constraint force is stable, effectively preventing changes in the rope length when subjected to external force and ensuring that the protective dimensions do not shift.

[0015] As a preferred embodiment of the present invention, the flexible protective rope adopts a multi-layer composite braided structure, with a high-strength tensile fiber core layer inside and a wear-resistant and tear-resistant protective skin layer on the outside. The multi-layer composite braided structure is interspersed with transverse binding filaments, which constrain the braided structure to prevent loosening due to long-term pulling. The high-strength tensile fiber core layer meets the load-bearing capacity standard for edge protection, and the wear-resistant and tear-resistant protective skin layer isolates the rope from cutting damage caused by hard debris on the construction site.

[0016] This design features a multi-layered composite braided structure that balances tensile strength and abrasion resistance. The inner fiber core provides ample protective load-bearing capacity, while the outer sheath resists abrasion from sand, gravel, and metal components at the construction site. Lateral binding strands maintain the integrity of the rope's braided structure, extending the rope's service life and reducing subsequent replacement and maintenance costs.

[0017] As a preferred embodiment of the present invention, the pole body is assembled with multiple sets of self-winding rope winding assemblies in vertical layers, and a vertical positioning separator is assembled between two adjacent sets of self-winding rope winding assemblies. The vertical positioning separator is engaged and fixed to the outer wall of the pole body to isolate the upper and lower winding components.

[0018] This layered self-winding rope assembly forms two standard protective layers, with vertical positioning separators isolating the two sets of winding components. This not only fixes the standard height of the double-layer protection but also prevents the upper and lower flexible ropes from tangling and interfering with each other after they extend, unifying the protection erection standard and eliminating the problem of substandard height during manual erection.

[0019] As a preferred embodiment of the present invention, the vertical positioning separator includes a locking plate with an arc-shaped cross section. The locking plate is locked onto the main body of the upright. A fixing sleeve is installed on one side of the locking plate. The fixing sleeve has a thread inside and is open at both ends. Telescopic rods are installed at the upper and lower openings of the fixing sleeve. The top end of the telescopic rod abuts against the self-winding rope assembly.

[0020] This feature includes an arc-shaped locking plate that fits onto the outer wall of the pole body for detachable locking installation. The threaded fixing sleeve, combined with the telescopic rods at both ends, bidirectionally abuts against the upper and lower self-winding rope assembly. The bidirectional limiting structure can simultaneously constrain the vertical displacement of the upper and lower winding components, making installation and disassembly convenient and allowing for flexible adjustment of the vertical spacing of the layered protection.

[0021] As a preferred embodiment of the present invention, the outer wall of the telescopic rod is provided with external threads, the telescopic rod is threadedly connected to the fixed sleeve, and the telescopic operation is performed by screwing, and a soft pad is installed on the outer end of the telescopic rod.

[0022] This threaded structure allows for precise adjustment of the telescopic rod's extension length, adapting to the limiting requirements of different specifications of self-winding rope reel assemblies. The end pads can buffer the squeezing and impact forces between the telescopic rod and the reel assembly, preventing hard contact that could cause wear and deformation of the assembly housing and extending the component's service life.

[0023] As a preferred embodiment of the present invention, a plurality of anti-slip strips are vertically installed on the outer wall of the pole body, and the inner wall of the self-winding rope assembly contacts the anti-slip strips to prevent the circumferential rotation of the self-winding rope assembly.

[0024] This feature, with its vertical anti-slip strips, increases the frictional resistance between the main body of the pole and the inner wall of the self-winding rope assembly, restricts the circumferential rotation of the winding assembly, prevents the fixed slot on the annular sleeve from shifting, ensures stable alignment of the buckles, and further enhances the assembly stability of the overall protective structure.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This new type of edge protection pole is adaptable to various opening shapes and eliminates blind spots in protection: This solution uses a flexible protective rope that can be freely stretched to replace the rigid metal telescopic components in the comparison document. The rope can be bent and stretched arbitrarily along the edge contour, which can adapt to conventional rectangular openings, as well as curved and irregular edge layouts, and completely cover the open edge, solving the technical defects of rigid protection that cannot adapt to irregular openings and has protective gaps.

[0026] 2. This new type of edge protection pole can be installed and dismantled by a single person, improving construction efficiency: the overall components are lightweight, and during installation, only the flexible protective rope is pulled out, and the end fixing buckle is inserted into the fixing groove of the opposite pole, and the locking mechanism is turned to complete the limit; during dismantling, the locking mechanism can be released to retrieve the rope, and no two people are required to cooperate throughout the process, which greatly reduces the manpower input and solves the problems of high self-weight of rigid protection and low efficiency of multi-person collaborative operation.

[0027] 3. In this new type of edge protection pole, the protection levels are standardized to avoid human operation deviations: the pole can be assembled with self-winding rope components in layers, and the vertical positioning separators precisely limit the installation positions of the upper and lower protection components, naturally forming a double-layer protection height benchmark that meets the standard requirements. It is not affected by the operation level of construction personnel and eliminates the safety hazards of substandard protection height.

[0028] 4. The new type of edge protection pole has a small storage space and a high turnover and reuse rate: After use, the flexible protective rope can be completely stored inside the ring sleeve, with no scattered protruding hard components. The space occupied for transportation and storage is greatly reduced. The high integration of parts makes them less likely to be lost or damaged, effectively increasing the frequency of cross-project turnover and solving the defects of traditional rigid protection with large storage volume and low reuse rate.

[0029] 5. In this new type of edge protection pole, the locking structure is stable and reliable, and has strong resistance to external disturbances: the threaded rod locking mechanism directly abuts the rope to lock the length, and the anti-slip strip on the outer wall of the pole restricts the circumferential rotation of the self-winding rope assembly. The multi-layer composite braided rope is tensile and wear-resistant, and is not easy to slip or loosen when subjected to impact or pulling, thus improving the overall stability of the protection structure.

[0030] 6. The new type of edge protection pole is flexible in installation and adjustment and adaptable to various opening specifications: the fixing slots are arranged at equal intervals along the ring-shaped ring, and the buckle connection position can be flexibly adjusted to adapt to different opening widths. There is no need to cut or splice components, saving material processing steps and reducing material waste. Attached Figure Description

[0032] 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.

[0033] This invention provides a novel edge protection pole, such as... Figures 1-4 As shown, it includes a vertical support pole body 1, a self-winding rope assembly 2 assembled on the outside of the pole body 1, a locking mechanism 3 for limiting the rope length, a detachable fixing buckle 4, and a retractable flexible protective rope 5. The main pole 1 serves as a vertical support unit, used to support multiple sets of self-winding rope coil assemblies 2 and to build a vertical frame for edge protection; The self-winding rope assembly 2 is a protective rope storage and extension adjustment unit. It internally stores the flexible protective rope 5 and relies on the locking mechanism 3 to lock and position the extended length. The fixing buckle 4, together with the fixing groove 23 on the outer wall of the self-winding rope assembly 2, realizes the lateral protective connection between the two upright bodies 1. After the flexible protective rope 5 extends, it forms a continuous edge protection barrier.

[0034] By disassembling the protective structure into modular units—a main pole 1, a self-winding rope assembly 2, a locking mechanism 3, a fixing buckle 4, and a flexible protective rope 5—each unit can be independently disassembled and assembled flexibly, adapting to various opening specifications on construction sites and exhibiting excellent reusability. The main pole 1 provides stable vertical support, the self-winding rope assembly 2 allows for free extension and retraction adjustment of the rope, the locking mechanism 3 ensures stable protective dimensions, the fixing buckle 4 simplifies lateral connection assembly, and the flexible protective rope 5 adapts to irregular edge contours. The synergy of these multiple components eliminates the shortcomings of traditional rigid protection, such as poor adaptability and improper erection.

[0035] In this embodiment, the self-winding rope assembly 2 is arranged vertically in layers along the main body 1, and a vertical positioning separator 7 is installed between two adjacent sets of self-winding rope assemblies 2; a support plate 11 is installed at the bottom of the main body 1, and the support plate 11 is bolted to the base 6 to fix the base surface; the flexible protective rope 5 is housed in the annular sleeve 21 inside the self-winding rope assembly 2, and multiple sets of fixing slots 23 are arranged in a ring on the outer wall of the annular sleeve 21, and the fixing buckle 4 is engaged with the fixing slot 23 to achieve horizontal protective assembly.

[0036] The self-winding rope assembly 2 is arranged in layers to form a double-layer standardized protective structure. The vertical positioning separator 7 isolates the upper and lower winding components to prevent the rope from getting tangled. The bottom support plate 11 of the pole body 1, together with the base 6, expands the force-bearing area to resist the horizontal thrust generated by the rope pulling and prevent the pole from overturning. The outer wall of the ring sleeve 21 has multiple sets of fixing slots 23 to provide multi-directional locking points. Construction personnel can freely choose the buckle assembly position according to the width of the opening and the contour of the edge, which greatly improves the adaptability of the protective structure.

[0037] Specifically, a support plate 11 is fixedly assembled at the bottom of the main body 1. The support plate 11 has multiple sets of bolt through holes. The support plate 11 is locked and fixed to the base 6 by bolts through the through holes. The base 6 is laid flat on the construction base surface to provide a support reference.

[0038] The support plate 11 has multiple bolt through holes, which can flexibly adjust the bolt locking points. The bolt locking connection structure is easy to disassemble and assemble, and there is no need to weld the main body 1 of the upright. The base 6 is laid flat to increase the contact area with the base surface, disperse the overall load of the upright, effectively avoid the lateral tilting force caused by the stretching of the flexible protective rope 5, improve the overall installation stability of the upright, and is suitable for various construction base surfaces such as concrete and steel structures.

[0039] Furthermore, the self-winding rope assembly 2 includes an annular sleeve 21. The annular sleeve 21 has a through-type rope outlet 22 on its side wall for the flexible protective rope 5 to pass through and extend. The outer wall of the annular sleeve 21 is integrally formed with several fixing slots 23. The end fixing buckle 4 of the flexible protective rope 5 of a single pole body 1 can be inserted into any fixing slot 23 of another pole body 1 to complete the lateral limitation.

[0040] The through-type rope outlet 22 limits the telescopic movement trajectory of the flexible protective rope 5, preventing twisting and knotting during rope storage and pulling out; the ring sleeve 21 has an integrally formed outer wall fixing groove 23 with higher structural strength and no risk of groove falling off. Multiple groove points can freely adjust the lateral protection span between the two uprights, eliminating the need for cutting and splicing components, saving on-site material processing procedures and reducing construction material waste.

[0041] Furthermore, the fixing slots 23 are evenly arranged in a ring at equal intervals along the outer wall of the annular sleeve 21, and all the openings of the fixing slots 23 face the outside of the annular sleeve 21. The slots are reserved with a locking cavity for the fitting of the fixing buckle 4.

[0042] The ring-shaped, equally spaced fixing slots 23 achieve 360° all-round clamping point coverage. For curved and irregularly shaped edges, the clamping angle can be adjusted arbitrarily, and the force is evenly distributed to avoid local stress concentration caused by single-point clamping. The opening design on the outside of the slot makes it easy for construction workers to complete the clamping and unclamping operation with one hand, reducing the difficulty of high-altitude edge operations.

[0043] Furthermore, the locking mechanism 3 adopts a threaded rod pressing structure, and a matching threaded hole is opened on the side wall of the annular sleeve 21. The threaded rod of the locking mechanism 3 is threadedly connected to the threaded hole, and the end of the threaded rod extends into the interior of the annular sleeve 21 to press against the flexible protective rope 5 to achieve length locking.

[0044] The threaded rod and the threaded hole of the annular sleeve 21 can be screwed together to adjust the tightening pressure steplessly. Construction personnel can adjust the tightening force according to the force on the rope to continuously limit the retraction and sliding of the flexible protective rope 5. The threaded locking structure has no elastic fatigue defects and can maintain a stable locking constraint force even after long-term repeated use, preventing external force from causing the protective span to shift and ensuring that the edge protection size is constant.

[0045] Furthermore, the flexible protective rope 5 adopts a multi-layer composite braided integrated molding structure, with a continuous high-strength tensile fiber core layer 51 inside, and a wear-resistant and tear-resistant protective skin layer 52 completely covered on the outside. Transverse binding filaments 53 are interwoven inside the braided layer and evenly distributed along the radial direction of the rope.

[0046] The high-strength tensile fiber core layer 51 provides sufficient tensile load-bearing capacity to meet the mechanical load-bearing specifications for building edge protection; the outer wear-resistant and tear-resistant protective skin layer 52 isolates the rope from cutting and abrasion by hard components such as sand, gravel and steel bars on the construction site, extending the service life of the rope; the radially evenly distributed transverse binding filament bundles 53 constrain the braided fibers to prevent them from loosening and falling off, ensuring the rope structure remains intact under long-term tensile operations and reducing the frequency of later maintenance and replacement.

[0047] Furthermore, multiple sets of vertical positioning separators 7 are vertically engaged and assembled on the outer wall of the pole body 1. The adjacent two layers of self-winding rope coil assemblies 2 are respectively limited on the upper and lower sides of the vertical positioning separators 7. The vertical positioning separators 7 isolate the expansion and contraction space of the upper and lower flexible protective ropes 5.

[0048] The vertical positioning separator 7 is assembled with snap-fit ​​without bolts. The installation position can be adjusted vertically along the main body 1 of the pole, accurately limiting the vertical reference height of the double-layer protection and eliminating the safety hazards of manual erection not meeting the height standard. The separator independently isolates the upper and lower winding units, avoiding mutual entanglement and interference between the two layers of flexible protective ropes 5 after they are pulled out, and simplifying the on-site deployment process.

[0049] Furthermore, the vertical positioning separator 7 includes an arc-shaped locking plate 71 and a hollow fixing sleeve 72 with built-in internal threads. The arc-shaped locking plate 71 fits against the outer wall of the main body 1 to achieve locking and positioning. The fixing sleeve 72 is integrally formed on the side of the arc-shaped locking plate 71, and the upper and lower ends of the fixing sleeve 72 are open.

[0050] The arc-shaped locking plate 71 is adapted to the outer wall of the main body 1 of the upright, and after locking, it fits tightly without slippage gap; the hollow fixing sleeve 72 with internal thread provides a bidirectional limiting assembly carrier, and the open structure at both ends can simultaneously assemble two sets of telescopic rods 73, realizing bidirectional vertical limiting of the upper and lower sets of self-winding rope winding components 2. One set of separators can simultaneously constrain two layers of winding units, simplifying the types of components.

[0051] Furthermore, the outer wall of the telescopic rod 73 is machined with continuous external threads, and the telescopic rod 73 is screwed into the interior of both ends of the fixed sleeve 72 to form a threaded pair fit. The end of the telescopic rod 73 away from the fixed sleeve 72 is fixedly fitted with a soft pad 74.

[0052] The extension length can be precisely adjusted by the threaded engagement of the telescopic rod 73 and the fixed sleeve 72 to adapt to the limiting requirements of different specifications of self-winding rope assembly 2. The spacing can be finely adjusted by turning. The end pad 74 is made of flexible buffer material to buffer the squeezing and impact force between the telescopic rod 73 and the housing of the self-winding rope assembly 2, avoid hard contact that causes wear and deformation of the housing, and improve the long-term durability of the component.

[0053] Furthermore, multiple anti-slip strips are fixed vertically on the outer wall of the pole body 1, and the inner wall of the annular sleeve 21 of the self-winding rope assembly 2 is tightly fitted with the surface of the anti-slip strips, increasing the frictional resistance of the contact surface between the two.

[0054] Vertical anti-slip strips are evenly distributed on the outer wall of the pole body 1, increasing the friction coefficient between the pole and the inner wall of the annular sleeve 21, limiting the circumferential rotational displacement of the self-winding rope assembly 2, ensuring the stable orientation of the fixing groove 23 on the outer wall of the annular sleeve 21, and ensuring accurate buckle engagement and alignment, avoiding failure of the lateral protective connection due to the rotation of the winding assembly, and improving the overall stability of the protective assembly.

[0055] When using the novel edge protection pole of the present invention, the equipment is first installed and deployed: the base 6 is laid flat on the pre-set position of the edge construction base surface, the support plate 11 is attached to the bottom end of the pole body 1, and bolts are used to pass through the through holes of the support plate 11 to lock and fix it above the base 6, thus completing the bottom fixation of a single pole body 1; the vertical positioning separator 7 is sequentially snapped and assembled along the vertical direction of the pole body 1, the extension length of the telescopic rod 73 is adjusted by turning it, and the upper and lower telescopic rods 73 respectively press against the upper and lower sets of self-winding rope coil assemblies 2, limiting the self-winding rope coil assembly 2 to the layer position of the pole body 1, and the circumferential rotation of the annular sleeve 21 is restricted by the anti-slip strip on the outer wall of the pole; multiple pole bodies 1 are evenly arranged according to the outline of the edge opening, thus completing the layout of all vertical support units. Subsequently, the flexible protective rope 5 is pulled out, and the fixing buckle 4 at the end of the rope is inserted into the fixing groove 23 on the outer wall of the annular sleeve 21 of the upright pole. The appropriate groove point is selected according to the width of the opening and the arc direction of the edge to complete the lateral protection connection. The threaded rod of the locking mechanism 3 is turned to press the flexible protective rope 5, lock the extension length of the rope, and complete the installation and deployment of the entire edge protection.

[0056] After the equipment is installed, the protective structure is debugged: check the bolt tightness of the bottom support plate 11 and base 6 of each pole body 1 in turn to confirm that there is no loosening or slippage; check the engagement of the fixing buckle 4 with the fixing slot 23 by moving it, and test the locking and unlocking functions of the rope by loosening and tightening the locking mechanism 3; observe whether there is any entanglement or interference between the upper and lower flexible protective ropes 5, adjust the length of the vertical positioning separator 7 and the telescopic rod 73 to correct the vertical position of the winding assembly, and enter the formal protective use state after debugging is correct.

[0057] Entering the formal protective use stage, workers carry out construction operations on the inside of the edge. The two layers of flexible protective ropes 5 form a standardized double-layer protective barrier. The high-strength tensile fiber core layer 51 bears the load generated by accidental impact and personnel leaning on it, while the outer wear-resistant and tear-resistant protective skin layer 52 resists the wear and tear of debris at the construction site. If the edge is an arc-shaped or irregularly shaped opening, the flexible protective rope 5 can bend freely with the contour. Multiple sets of ring-shaped fixing slots 23 flexibly adjust the buckle docking angle to completely cover the edge of the fall from the air, with no blind spots in protection. The anti-slip strip on the outer wall of the pole continuously restrains the circumferential rotation of the self-winding rope assembly 2, and the threaded rod of the locking mechanism 3 continuously presses the rope, maintaining a constant protective span throughout the entire process and avoiding the safety risk of falling from heights.

[0058] If the protective span needs to be adjusted during construction, simply reverse the locking mechanism 3 to release the rope compression limit, stretch or retract the flexible protective rope 5 to the target length, and then tighten the locking mechanism 3 again. If the spacing of the uprights needs to be changed, simply pull the fixing buckle 4 out of the original fixing slot 23 and replace it with the corresponding slot to re-engage. The entire adjustment operation can be completed independently by a single person without the need for multiple people to work together.

[0059] After the construction task is completed, dismantle and store the protective uprights: pull out all the fixing buckles 4 from the corresponding fixing slots 23 in sequence, turn the locking mechanism 3 in the opposite direction to release the flexible protective rope 5, and the rope will automatically retract into the annular sleeve 21; loosen the vertical positioning separator 7 telescopic rod 73, and remove the layered self-winding rope assembly 2; loosen the locking bolts between the support plate 11 and the base 6, and separate the upright body 1 from the base surface; stack all components in categories for storage, and the flexible protective rope 5 is completely retracted into the annular sleeve 21 without any protruding components. The storage space is small, and there are no easily lost or scattered small parts. It can be directly transferred to the next construction project for repeated use. The entire equipment operation process is completed.
