Description

Technical Field

[0001] This invention relates to the field of guardrail technology, and in particular to an integrated flexible isolation guardrail. Background Technology

[0002] In hydropower plant generator unit maintenance, to achieve physical isolation between the maintenance unit and the operating unit, safety isolation facilities must be deployed before maintenance. Currently, the commonly used isolation solution in the industry is a combination of square columns and stainless steel guardrails. Each unit requires different levels of maintenance work every year. During maintenance, the isolation fence needs to be moved from the generator floor to the tailrace pipe floor (a drop of 27m between the two floors). The maintenance of a single unit requires the installation of 6 layers of this type of isolation fence, resulting in a large amount of fence usage and complex deployment scenarios. The columns and guardrails of the isolation fence are both rigid structures, heavy and numerous. During maintenance, they must be manually moved to each working floor via stairs, which not only consumes a lot of manpower and time, but also easily causes workers to be injured by bumps and falls due to the weight of the fence and the narrow path (stairs) during the transportation process. The safety risks are prominent, and the transportation and installation efficiency is low and the safety risks are high. The existing fencing suffers from poor layout and insufficient reliability. Limited by manual installation precision and site space conditions, it is difficult to maintain a straight position after installation. In areas where the space dimensions do not match the fencing specifications, two sections of the fencing must be partially overlapped to achieve isolation. Storage is inconvenient. After unit maintenance, a large number of scattered posts and guardrails must be collected one by one. This type of rigid fencing structure is fragmented, requiring significant storage space for storage, and is prone to collision damage during handling and stacking, further increasing subsequent maintenance costs. Summary of the Invention

[0003] This invention is based on the inventor's discoveries and understanding of the following facts and problems:

[0004] The isolation fence is inconvenient to transport and install.

[0005] The present invention aims to at least partially solve one of the technical problems in the related art.

[0006] To address this, embodiments of the present invention propose an integrated flexible isolation fence, comprising an integrated post, flexible ropes, a rope winding mechanism, and end attachment points. The integrated post has casters and fixed points at its bottom. The side of the integrated post is slidably connected to a movable fence gate via guide sleeves. The flexible ropes comprise multiple steel wire ropes arranged at equal intervals along the vertical direction. The rope winding mechanism is arranged on the integrated post and includes a drive unit, a drum, a first chain, and a first gear. Each drum corresponds to one of the steel wire ropes and is pivotally connected to the integrated post. The first gear is located at one end of the drum. The drive unit is connected to the first gear via the first chain to drive the drum to rotate. The end attachment points include an aluminum profile and a tensioner. The tensioner is located on the aluminum profile, which is mounted on a concrete structure. The tensioner is applied to each steel wire rope to tighten it.

[0007] The present invention has the advantages and technical effects of high handling and installation efficiency, good space adaptability, and low maintenance cost.

[0008] In some embodiments, a rope locking mechanism is further included, the rope locking mechanism including a handle, a rotating wheel, a locking member, a second gear and a second chain, the handle being drivenly connected to one of the rotating wheels, the rotating wheel being connected to the integrated column, the steel wire rope being wound on the rotating wheel, the rotating wheel and the steel wire rope being in one-to-one correspondence, the second gear being arranged at one end of the rotating wheel, the second chain being sleeved on the second gear and the adjacent second gear to drive the rotating wheel to rotate synchronously with the adjacent rotating wheel, and the locking member being connected to the integrated column and detachably connected to the handle to lock the handle.

[0009] In some embodiments, an intermediate hanging point is also included, which includes an aluminum profile and a plurality of wire rope pressure plates, wherein each wire rope pressure plate corresponds to a wire rope, the aluminum profile is connected to a concrete column, and the wire rope pressure plate has a slot for accommodating the wire rope.

[0010] In some embodiments, the system further includes an intermediate support column, which includes a base and an upright column. The bottom of the upright column is connected to the base, and the upright column is provided with a plurality of wire rope hanging points, each corresponding to a wire rope.

[0011] In some embodiments, the wire rope attachment point is provided with a through hole for the wire rope to pass through, and the diameter of the through hole is larger than the diameter of the wire rope.

[0012] In some embodiments, a telescopic support is further included. The telescopic support includes a first fixing member, a second fixing member, a telescopic rod, and a movable rod. The first fixing member is detachably connected to a first side of the concrete column. The fixed end of the telescopic rod is connected to the fixing member. The telescopic end of the telescopic rod is connected to a support rod. The support rod is provided with a plurality of guide wheels. The first end of the movable rod is pivotally connected to the support rod. The second end of the movable rod is pivotally connected to the second fixing member. The second fixing member is connected to a second side of the concrete column.

[0013] In some embodiments, the guide wheels are divided into two groups, and the two groups of guide wheels are arranged symmetrically about the support rod, with each guide wheel in the group corresponding to a steel wire rope.

[0014] In some embodiments, the end of the support rod near the ground is provided with a caster wheel that abuts against the ground.

[0015] In some embodiments, the integrated column is further provided with a support wheel, the support wheel being rotatable relative to the integrated column, and the support wheel abutting against the bottom of the movable guardrail gate.

[0016] In some embodiments, the guide sleeve includes a first semicircle and a second semicircle, which are joined together to form an annulus to restrict the moving guardrail gate. The first semicircle is connected to the integrated post, and the second semicircle is detachably connected to the first semicircle.

[0017] This application has the following advantages: The second gear and second chain work together to achieve synchronous rotation of multiple sets of pulleys and wire ropes, ensuring consistent locking actions of multiple wire ropes. The locking element and handle are detachably connected, forming a mechanical lock to prevent accidental operation. Each pulley corresponds to a wire rope, achieving precise locking control of a single wire rope. Synchronous rotation avoids uneven locking of multiple wire ropes, ensuring consistent tension across all wire ropes, improving isolation continuity. Combined with the rope winding mechanism of the integrated column, it forms a synchronized locking mechanism for winding and unwinding. The slot limits the wire rope's position, preventing lateral displacement during long-distance deployment. Combined with the support function of the intermediate hanging point, it effectively suppresses sagging in the middle of the wire rope, improving the straightness and continuity of the isolation. The hanging point prevents multiple wire ropes from tangling or rubbing against each other in the middle, ensuring balanced force on the wire ropes, reducing wear, and extending service life. The intermediate support column acts as a central support point to distribute overall tension, preventing excessive stretching and deformation of the wire rope. The through-holes at the hanging points reduce frictional loss during wire rope installation, retrieval, and use, lowering the risk of wire rope breakage. The ample through-hole size facilitates quick wire rope installation and adjustment, improving the deployment and retrieval efficiency of the isolation barrier. The telescopic support, through the cooperation of the first and second fixing components and the moving rod, counteracts the lateral force during telescopic rod extension and retraction, preventing bending deformation and enhancing structural stability. This allows for rapid adjustment of the isolation width, adapting to frequently switching walking paths such as those near the power plant governor's return oil tank. Two sets of symmetrically arranged guide wheels ensure the wire rope remains on the preset isolation path, ensuring smooth turning. Universal wheels at the end of the support rod reduce resistance during telescopic support adjustment, making width adjustment easier, distributing stress to prevent support rod deformation, and extending the service life of the telescopic support. The rolling friction of the integrated column support wheels significantly reduces resistance during gate opening and closing, making the moving barrier gate slide more smoothly. The annular splicing structure of the guide sleeve provides all-around lateral restraint for the moving barrier gate, preventing deviation and wobbling during gate sliding, ensuring flexible opening and closing and precise positioning after closing, improving isolation sealing.

[0026] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0027] An embodiment of the present invention proposes an integrated flexible isolation fence, comprising an integrated post 1, a flexible rope, a rope winding mechanism 2, and end attachment points 4. The integrated post 1 has a caster wheel 101 and a fixing point 105 at its bottom. The side of the integrated post 1 is slidably connected to a movable guardrail gate 104 via a guide sleeve 102. The flexible rope includes multiple steel wire ropes 5 arranged at equal intervals along the vertical direction. The rope winding mechanism 2 is arranged on the integrated post 1 and includes a drive component, a drum 201, a first chain 202, and a first gear. 203. Drum 201 corresponds one-to-one with wire rope 5. Drum 201 is pivotally connected to integrated column 1. First gear 203 is arranged at one end of drum 201. The drive unit is connected to the first gear 203 via first chain 202 to drive drum 201 to rotate. End attachment point 4 includes aluminum profile 401 and tensioner 402. Tensioner 402 is arranged on aluminum profile 401, which is arranged on concrete structure. Tensioner 402 and wire rope 5 are used one-to-one to tighten wire rope 5. Concrete structure refers to the wall or column of concrete building at the end of the isolation area in a factory or maintenance scene.

[0028] The casters 101 at the bottom of the integrated column 1 complement the fixing point 105. The casters 101 allow the integrated column 1 to move flexibly, eliminating the need for multiple people to carry it, thus meeting the transportation needs of multi-level maintenance scenarios in power plants. The fixing point 105 securely positions the integrated column 1 in a preset location, preventing displacement during isolation. The sliding connection between the guide sleeve 102 and the movable guardrail gate 104 provides stable guidance for the gate, ensuring smooth lateral movement without affecting the enclosure of the isolation area, while facilitating access for maintenance personnel. The flexible rope uses multiple steel wire ropes 5 arranged vertically at equal intervals to form a continuous protective barrier. Compared to traditional rigid fences, the flexibility of the steel wire ropes 5 adapts to complex layout paths, while the multiple ropes arrangement enhances isolation strength, preventing personnel from crossing or accidentally entering. The steel wire ropes 5 are lighter, making transportation and placement more convenient. Warning signs can also be easily hung on the steel wire ropes 5. The rope winding mechanism 2, through the transmission cooperation of the drive unit, the first chain 202, and the first gear 203, enables multiple drums 201 to rotate synchronously. Each drum 201 corresponds one-to-one with a steel wire rope 5, ensuring consistent winding and unwinding of multiple steel wire ropes 5, shortening installation and retrieval time, and solving the problem of low efficiency in traditional segmented fencing installation. The drive unit's transmission operation is convenient and reduces labor intensity. The aluminum profile 401 at the end hanging point 4 provides a stable installation base for the tensioner 402. Its fixing method to the concrete structure ensures firm end support. The one-to-one correspondence between the tensioner 402 and the steel wire rope 5 allows for precise adjustment of the tension of each steel wire rope 5, preventing local slack from affecting the isolation effect. The integrated column 1 is made of welded stainless steel plate. The fixing point 105 can be fixed to the ground with bolts, and stainless steel threaded sleeves are pre-embedded at the fixing point 105 on the ground. The bottom universal wheels 101 are handle-type casters. The movable guardrail gate 104 can be made of welded 304 stainless steel pipe. The wire rope 5 is made of 304 stainless steel, with a diameter of 5mm, a breaking load greater than 10kN, a spacing of 300mm between the wire ropes 5, and a height of 1200mm for the top wire rope 5.

[0029] In some embodiments, a rope locking mechanism 3 is also included. The rope locking mechanism 3 includes a handle 301, a rotating wheel 302, a locking member, a second gear 303, and a second chain 304. The handle 301 is connected to a rotating wheel 302, which is connected to an integrated column 1. A steel wire rope 5 is wound on the rotating wheel 302, and the rotating wheel 302 corresponds one-to-one with the steel wire rope 5. The second gear 303 is arranged at one end of the rotating wheel 302. The second chain 304 is sleeved on the second gear 303 and the adjacent second gear 303 to drive the rotating wheel 302 to rotate synchronously with the adjacent rotating wheel 302. The locking member is connected to the integrated column 1 and detachably connected to the handle 301 to lock the handle 301.

[0030] Specifically, through the transmission cooperation between the second gear 303 and the second chain 304, multiple rotating wheels 302 rotate synchronously. Each rotating wheel 302 corresponds one-to-one with a steel wire rope 5, ensuring consistent locking actions across all steel wire ropes 5. This prevents localized slackness or over-tightening, ensuring the overall flatness of the isolation barrier. The transmission connection between the handle 301 and the rotating wheel 302 allows operators to adjust the locking action with a simple rotation, eliminating the need for complex tools and meeting the needs of rapid deployment at maintenance sites. The winding of the steel wire rope 5 around the rotating wheel 302 enhances the connection stability between the steel wire rope 5 and the rotating wheel 302, reducing the risk of slippage.

[0031] The locking element is fixed to the integrated column 1 and detachably connected to the handle 301. When the wire rope 5 is adjusted to a suitable tension by the tensioner 402, the locking element locks the handle 301, thus fixing the position of the rotating wheel 302. This effectively prevents the handle 301 from rotating due to vibration, accidental contact, or prolonged use, thereby preventing the wire rope 5 from loosening and sinking, ensuring rope tensioning and locking. The mechanical locking is stable, suitable for the complex environment of power plant maintenance sites, and requires no frequent maintenance. The locking element can be a buckle, rope loop, or other structure.

[0032] The rope locking mechanism 3, rope winding mechanism 2, and end attachment point 4 work together. The rope winding mechanism 2 enables the synchronous winding and unwinding of the wire rope 5, the tensioner 402 adjusts the tension, and the rope locking mechanism 3 securely locks the rope, improving the efficiency of the isolation arrangement while ensuring the safety and durability of the isolation. Synchronous rotation reduces uneven stress on multiple wire ropes 5, lowers the wear rate of individual wire ropes 5, extends the overall service life of the equipment, and further reduces the maintenance costs of power plant maintenance. The tensioner 402 can be a rectangular component with threaded eyelets at both ends for hooking the wire rope 5 and the end attachment point 4. The end of the eyelet is equipped with a threaded rod, and the rectangular component has threaded holes. Changing the length of the threaded rod entering the rectangular component adjusts the overall length of the tensioner 402, thereby adjusting the tension of the wire rope 5.

[0033] In some embodiments, the system also includes an intermediate hanging point 6, which includes an aluminum profile 401 and a plurality of steel wire rope 5 pressure plates. The steel wire rope 5 pressure plates correspond one-to-one with the steel wire ropes 5. The aluminum profile 401 is connected to the concrete column. The steel wire rope 5 pressure plates have slots for accommodating the steel wire ropes 5.

[0034] Specifically, the aluminum profile 401 connects to the concrete column to provide an installation carrier for the wire rope 5 pressure plate. The aluminum profile 401 combines lightweight design with structural strength, adapting to the fixed deployment requirements of the maintenance site. The pressure plate corresponds one-to-one with the wire rope 5, ensuring precise support for each wire rope 5. The slots on the pressure plate tightly accommodate the wire rope 5, achieving both lateral restraint to prevent multiple wire ropes from tangling or misaligning, and longitudinal tension adjustment without affecting the flexibility of installation and use. The slots' fitting and restraining effect effectively suppresses sagging in the middle of the wire rope 5 during long-distance isolation, keeping the isolation area straight and regular, improving the continuity of the isolation, and reducing the safety hazard of personnel accidentally entering dangerous areas through gaps. The one-to-one matching design simplifies the installation process; the wire rope 5 can be quickly embedded into the slot for positioning without complex adjustments, significantly reducing the labor intensity of on-site deployment and improving the efficiency of maintenance isolation setup.

[0035] The tensioners 402 at the middle hanging point 6 and the end hanging point 4, along with the rope locking mechanism 3 of the integrated column 1, work together to provide support. The central support disperses the overall tension of the wire rope 5, preventing deformation or wear of the wire rope 5 due to excessive local stress, thus extending the service life of the equipment. The combination of the aluminum profile 401 and the wire rope 5 pressure plate can adapt to the complex environment of power plant maintenance sites, enhancing the structural reliability and spatial adaptability of the entire isolation fence.

[0036] In some embodiments, the system further includes an intermediate support column, which includes a base and an upright column. The bottom of the upright column is connected to the base, and multiple wire rope 5 hanging points are provided on the upright column, with each wire rope 5 hanging point corresponding to a wire rope 5.

[0037] Specifically, the base and the uprights form a support structure. The base increases the contact area with the ground, ensuring that the central support does not tip over when bearing the tension of the steel wire rope 5. The uprights provide an installation benchmark for the hanging points of the steel wire rope 5. Each hanging point corresponds one-to-one with the steel wire rope 5, achieving independent support for each steel wire rope 5. This avoids interference between multiple steel wire ropes 5 in the middle, ensuring even force distribution and meeting the support requirements of long-distance isolation scenarios. The hanging points effectively prevent wear caused by entanglement or friction of multiple steel wire ropes 5, reducing the risk of breakage and extending the service life of the flexible ropes. As the central support point for long-distance isolation paths, the central support disperses the overall tension of the steel wire rope 5, preventing excessive stretching and deformation due to large spans, ensuring the straightness and continuity of the isolation area, and solving the problem of loosening easily in traditional fences over long distances.

[0038] The central support column, along with the central hanging point 6 and end hanging points 4, forms a multi-point support system, enhancing the structural stability of the entire guardrail. This design is particularly suitable for isolation needs involving extremely long distances or complex paths. The integrated structure of the base and column is reliable, easy to install, and requires no complex adjustments, improving the efficiency of deploying isolation measures at the maintenance site and reducing labor intensity and maintenance costs.

[0039] In some embodiments, the attachment point of the wire rope 5 is provided with a through hole for the wire rope 5 to pass through, and the diameter of the through hole is larger than the diameter of the wire rope 5.

[0040] Specifically, the diameter of the through hole is larger than that of the wire rope 5, leaving a clearance for installation and movement. This allows for smoother threading and adjustment of the wire rope 5, avoiding jamming or installation resistance caused by excessive tightness in the hole. It simplifies the deployment and retrieval process of the wire rope 5 in long-distance isolation scenarios, reducing the labor intensity of on-site operations. The clearance reduces frictional contact between the wire rope 5 and the inner wall of the through hole during use, especially during switching between isolation areas or slight shaking of the wire rope 5. This prevents surface wear caused by hard friction, reduces the risk of breakage, extends the service life of the flexible rope, and reduces the frequency and cost of equipment maintenance and replacement. The through hole enables precise positioning and support of the wire rope 5, while the clearance ensures the freedom of movement of the wire rope 5 without affecting the overall tension. Combined with the intermediate hanging point 6 and the end hanging point 4, this enhances the stability of the isolation structure, improves the operational convenience and adaptability of the entire isolation barrier, and meets the complex usage requirements of power plant maintenance sites.

[0041] In some embodiments, the system further includes a telescopic support 8, which includes a first fixing member 801, a second fixing member 802, a telescopic rod 803, and a movable rod 804. The first fixing member 801 is detachably connected to a first side of the concrete column. The fixed end of the telescopic rod 803 is connected to the fixing member, and the telescopic end of the telescopic rod 803 is connected to a support rod 806. A plurality of guide wheels 805 are provided on the support rod 806. The first end of the movable rod 804 is pivotally connected to the support rod 806, and the second end of the movable rod 804 is pivotally connected to the second fixing member 802. The second fixing member 802 is connected to a second side of the concrete column.

[0042] Specifically, the first fixing member 801 and the second fixing member 802 are symmetrically connected to both sides of the concrete column. The angle between the plane of the first side and the plane of the second side of the concrete column is a right angle, and the first fixing member 801 is perpendicular to the second fixing member 802. The first fixing member 801 and the second fixing member 802 form a stable installation reference. The telescopic rod 803 directly adjusts the width of the support by telescopic extension and retraction. The pivotal connections at both ends of the movable rod 804 can adaptively adjust their angles as the telescopic rod 803 extends and retracts, assisting in the distribution of force. The guide wheel 805 on the support rod 806 provides guiding support for the wire rope 5. The overall structure balances installation stability and adjustment flexibility. Changing the length of the telescopic rod 803 can change the distance of the wire rope 5 relative to the concrete column, thereby realizing the movement of the position of the wire rope 5.

[0043] The telescopic pole 803 and the movable pole 804 work together to achieve flexible adjustment of the isolation width and direction, which can quickly respond to the spatial isolation needs of different sizes. It is especially suitable for walking passages that need to be frequently switched, such as next to the oil tank of the power plant speed governor, and solves the problem of poor space adaptability of traditional fences. The guide wheel 805 can reduce the friction interference when the wire rope 5 slides. Together with the telescopic pole 803, it ensures that the wire rope 5 is smoothly extended and retracted without jamming or tangling, and improves the efficiency of switching isolation areas.

[0044] In some embodiments, the guide wheels 805 are divided into two groups, and the two groups of guide wheels 805 are arranged symmetrically about the support rod 806. Each group of guide wheels 805 corresponds one-to-one with the wire rope 5.

[0045] Specifically, two sets of guide wheels 805 are symmetrically arranged about the support rod 806, providing bidirectional support and limiting the movement of the wire rope 5 from both sides. Each set of guide wheels 805 corresponds one-to-one with the wire rope 5, ensuring that each wire rope 5 has an independent guiding channel. This prevents multiple wire ropes 5 from tangling and interfering with each other during sliding, resulting in more precise positioning. Symmetry evenly distributes the force during guidance, reducing the offset wear caused by uneven load distribution on one side of a single guide wheel 805, and improving the stability of the guiding structure. Bidirectional limiting prevents the wire rope 5 from shifting or falling off during adjustment, isolation deployment, or use of the telescopic bracket 8, ensuring that the wire rope 5 always remains on the preset isolation path, guaranteeing the continuity and enclosure of the isolation area, and preventing safety gaps caused by wire rope 5 displacement. The one-to-one matching relationship ensures that each wire rope 5 is subjected to balanced force, avoiding localized tension concentration caused by guiding deviation, reducing frictional wear between the wire rope 5 and the guide wheel 805, and extending the service life of the flexible rope and the guide wheel 805.

[0046] When the width of the support is adjusted, the wire rope 5 can slide smoothly along the symmetrical guide wheel 805 without jamming or tangling, improving the efficiency of switching between isolation areas; at the same time, with the support and tension of the middle hanging point 6 and the end hanging point 4, the stability of the overall isolation structure is strengthened, making the isolation guardrail more suitable for the complex paths and frequent switching isolation needs of power plant maintenance sites.

[0047] In some embodiments, the end of the support rod 806 near the ground is provided with a caster wheel 101 that abuts against the ground.

[0048] Specifically, a caster wheel 101 is installed at the end of the support rod 806 near the ground, which abuts against the ground. This converts the sliding friction of the support rod 806 during movement into rolling friction, reducing the resistance when adjusting the width of the telescopic bracket 8. This makes operation easier and smoother, suitable for scenarios in power plant maintenance sites where frequent switching of isolation areas is required. No extra effort is needed to push the support rod 806, improving the efficiency of isolation layout and adjustment. The caster wheel 101 can effectively distribute the vertical load borne by the support rod 806, preventing the support rod 806 from bending and deforming due to its own weight, the tension of the wire rope 5, or uneven ground, protecting the structural integrity of the telescopic bracket 8 and extending its service life. At the same time, the rolling characteristics of the caster wheel 101 do not affect the guiding and supporting function of the support rod 806 for the wire rope 5, ensuring that the wire rope 5 always maintains a stable stress and positioning state.

[0049] In some embodiments, the integrated column 1 is further provided with a support wheel 103, which can rotate relative to the integrated column 1, and the support wheel 103 abuts against the bottom of the movable guardrail gate 104.

[0050] Specifically, the support roller 103 can rotate relative to the integrated column 1, converting the sliding friction of the movable guardrail gate 104 into rolling friction, significantly reducing the resistance to gate movement. Simultaneously, its contact with the bottom of the gate provides stable support, preventing sagging and deformation due to its own weight, and ensuring the precision of the fit between the gate and the guide sleeve 102. The combination of support and resistance reduction by the support roller 103 makes opening and closing the movable guardrail gate 104 easier and smoother, improving the efficiency of personnel entering and exiting the isolation area, preventing excessive friction between the gate and the guide sleeve 102 caused by sagging, reducing component wear, extending the service life of the movable guardrail gate 104 and the guide sleeve 102, and reducing equipment maintenance frequency and costs.

[0051] The support roller 103 works in conjunction with the guide sleeve 102 on the integrated column 1. The guide sleeve 102 provides lateral guidance, while the support roller 103 provides bottom support. This dual protection ensures precise sliding of the door and allows it to fit tightly against the integrated column 1 without any gaps when closed. It balances convenient passage with enhanced isolation safety, making it perfectly suited for the frequent opening and closing of doors and the need for reliable isolation in power plant maintenance sites.

[0052] In some embodiments, the guide sleeve 102 includes a first semicircle and a second semicircle, which are joined together to form an annulus to restrict the movement of the guardrail gate 104. The first semicircle is connected to the integrated post 1, and the second semicircle is detachably connected to the first semicircle.

[0053] Specifically, the first semicircle is fixedly connected to the integrated column 1, and the second semicircle is detachably assembled with the first semicircle to form a ring structure. This ring structure restricts the movement trajectory of the movable guardrail gate 104 from all directions around the gate, ensuring that the gate always slides smoothly in the lateral direction and avoiding deviation or shaking. The wrapping nature of the ring structure makes the fit between the gate and the guide sleeve 102 tighter, improving connection stability. The installation, disassembly, or replacement of the guide sleeve 102 component can be achieved without completely removing the integrated column 1, making the operation flexible and convenient.

[0054] The ring-shaped assembly structure ensures the guiding accuracy of the gate while avoiding the problems of cumbersome installation and inconvenient maintenance of the integrated guide sleeve 102, greatly simplifying the inspection and replacement process and reducing maintenance costs. It reduces local friction when the gate slides, avoids excessive wear of components, and extends the service life of the gate and guide sleeve 102, making it suitable for frequent use scenarios in power plant maintenance sites.
