Description

Technical Field

[0001] This application relates to the field of high-altitude operations technology, and in particular to a fall-prevention climbing system. Background Technology

[0002] With the development of transmission line operation and maintenance technology, high-altitude operation safety protection technology has been widely used. In order to meet the fall prevention safety requirements for construction, operation and maintenance and repair work on towers, guide rail fall protection technology has emerged. This technology uses guide rails on towers in conjunction with fall protection devices to achieve safety protection for workers.

[0003] In related technologies, guide rail-type fall arrestor rails are usually fixed to the existing angle steel of the existing iron tower using clamps or bolts, and high-altitude operations are achieved through the sliding cooperation of fall arrestor devices.

[0004] However, the aforementioned fall protection method of adding guide rails later has problems such as insufficient reliability due to structural separation, complex and costly high-altitude installation, and easy damage to the original structure of the tower. Summary of the Invention

[0005] Therefore, it is necessary to provide a fall-prevention climbing system to address the problems of insufficient reliability due to structural separation, complex and costly high-altitude installation, and easy damage to the original structure of the tower in the related technologies that rely on the later addition of guide rails for fall prevention.

[0006] This application provides a fall-prevention climbing system, which includes:

[0007] An iron tower, comprising at least two stacked tower layers, each tower layer having a first main member, the first main members in each tower layer being interconnected along the stacking direction of the tower layers;

[0008] The guide rail assembly includes at least two splicing segments that are connected one-to-one with the first main material, and the splicing segments are integrally formed with the first main material, and each splicing segment is connected to the other along the stacking direction of the tower layer;

[0009] A climber for slidingly engaging with the guide rail assembly.

[0010] The fall protection climbing system described in this application, by integrally molding the splicing sections with the first main material, improves the overall structural strength and reliability of the guide rail assembly and the tower. It also reduces the post-assembly process between the guide rail assembly and the tower, eliminating the damage to the original tower structure caused by post-assembly. Furthermore, it avoids safety hazards such as structural separation, insufficient reliability, fretting wear, damage to the tower's anti-corrosion layer, or loosening due to installation stress caused by post-assembly. In addition, the splicing sections of the fall protection climbing system are connected one-to-one with the first main material. Thus, during tower construction, adjacent splicing sections can automatically complete the assembly connection when adjacent first main materials are aligned. This reduces the need for high-altitude installation of the guide rail assembly after the tower is built, as is done in traditional technologies, improving the installation efficiency of the fall protection climbing system and reducing installation costs.

[0011] In one embodiment, one end of the splicing segment is provided with a first positioning part, and the other end of the splicing segment is provided with a second positioning part, and each splicing segment is positioned and engaged sequentially through the first positioning part and the second positioning part.

[0012] In one embodiment, the splicing segment includes a slide rail body and a positioning rod. The slide rail body is hollow, and the positioning rod passes through the slide rail body and is fixed relative to the slide rail body. One end of the positioning rod protrudes from the slide rail body and the protruding part is the first positioning part, and the other end of the positioning rod is recessed relative to the end of the slide rail body and the recessed part is the second positioning part.

[0013] In one embodiment, the slide rail body includes a base and a sliding part, the base being integrally formed with the first main material, and the sliding part being used for the climber to slide and engage.

[0014] In one embodiment, the cross-sectional shape of the sliding part is configured as circular or elliptical.

[0015] In one embodiment, the fall-prevention climbing system includes a reinforcement member for locking the base to the first main material.

[0016] In one embodiment, the climber includes a first slider, a second slider, a locking switch, and a self-locking mechanism. The first slider and the second slider are closable in a direction that moves closer or further away from each other, such that the first slider and the second slider can be slidably engaged or disengaged from the guide rail assembly. The locking switch is used to lock or unlock the opening and closing movement between the first slider and the second slider. The self-locking mechanism is rotatably connected between the first slider and the second slider, and the self-locking mechanism can rotate relative to the first slider and the second slider to abut against and be confined within the guide rail assembly.

[0017] In one embodiment, the climber includes a speed-sensing self-locking module connected to the self-locking mechanism. The speed-sensing self-locking module is used to sense the speed between the climber and the guide rail assembly. When the speed reaches a preset value, the speed-sensing self-locking module is used to drive the self-locking mechanism to abut against and limit itself to the guide rail assembly.

[0018] In one embodiment, the climber further includes a stop mechanism for manual operation to abut and limit the guide rail assembly.

[0019] In one embodiment, the tower layer is provided with a positioning mechanism, and two adjacent tower layers are positioned and cooperated with each other through their respective mechanisms to be stacked. Attached Figure Description

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0028] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0029] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0030] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0031] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0032] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0033] Considering that in related technologies, guide rails for fall arrest typically use clamps or bolts to attach to the existing angle steel of an existing iron tower, and then use fall arrest devices to slide and cooperate to achieve high-altitude operations, this method of adding guide rails later has problems such as insufficient reliability due to structural separation, complex and costly high-altitude installation, and easy damage to the original structure of the iron tower. This application provides a fall arrest climbing system that can improve structural strength and reliability, will not damage the original structure of the iron tower 100, and saves the high-altitude installation process.

[0034] Please see Figure 1 In some embodiments, the fall-prevention climbing system 10 provided in this application may include a tower 100, a guide rail assembly 200, and a climber 300, wherein the climber 300 is... Figure 5 As shown in the diagram. Tower 100 comprises at least two stacked tower layers 110. Please refer to... Figure 2 and Figure 3 As shown, each tower layer 110 is provided with a first main material 111, and the first main materials 111 in each tower layer 110 are interconnected along the stacking direction of the tower layers 110. The guide rail assembly 200 includes at least two splicing segments 210 that are connected one-to-one with the first main materials 111, and the splicing segments 210 are integrally formed with the first main materials 111. Each splicing segment 210 is interconnected along the stacking direction of the tower layers 110. The climber 300 is used to slide and engage with the guide rail assembly 200.

[0035] The fall-prevention climbing system 10 described in this application improves the overall structural strength and reliability of the guide rail assembly 200 and the iron tower 100 by integrally molding the splicing section 210 with the first main material 111. It also reduces the post-assembly process between the guide rail assembly 200 and the iron tower 100, eliminating the problem of damage to the original structure of the iron tower 100 during the post-assembly process. At the same time, it avoids safety hazards such as structural separation, insufficient reliability, fretting wear, damage to the anti-corrosion layer of the iron tower 100, or loosening due to installation stress caused by post-assembly between the guide rail assembly 200 and the iron tower 100. Furthermore, the splicing sections 210 of the aforementioned fall protection climbing system 10 are connected one-to-one with the first main material 111. Thus, during the construction of the tower 110, adjacent splicing sections 210 can automatically complete assembly and connection when adjacent first main materials 111 are aligned. This reduces the need for high-altitude installation of the guide rail assembly 200 after the tower 100 is constructed, as is done in traditional technologies, improving the installation efficiency of the fall protection climbing system 10 and reducing installation costs. Specifically, the guide rail assembly 200 is manufactured in the factory, and the tower 110 is hoisted segment by segment on the construction site as in a conventional tower erection process. The splicing sections 210 of the guide rail assembly 200 are installed along with the tower 100 in one go, eliminating all high-altitude post-installation work and significantly saving installation time and costs for the fall protection climbing system 10.

[0036] In addition, the aforementioned fall-prevention climbing system 10 of this application, by integrally molding the splicing section 210 with the first main material 111, also helps to maintain the aesthetics of the fall-prevention climbing system 10 and avoids the problem of the guide rail assembly 200 being structurally inconsistent with the tower 100 and having a messy appearance due to its retrofitting form.

[0037] It should be noted that the iron tower 100 mentioned above in this application includes a tower body composed of main materials, diagonal materials and auxiliary materials, wherein the main materials are configured as the longitudinal main load-bearing components of the iron tower 100, and the aforementioned first main material 111 refers to any one of the main materials of the iron tower 100.

[0038] Combination Figure 2 and Figure 3 As shown, in some embodiments, one end of the splicing segment 210 is provided with a first positioning part 2121, and the other end of the splicing segment 210 is provided with a second positioning part 2122. Each splicing segment 210 is positioned and engaged sequentially by the first positioning part 2121 and the second positioning part 2122, which can improve the installation positioning accuracy of adjacent splicing segments 210.

[0039] Optionally, the aforementioned first positioning part 2121 and second positioning part 2122 may be implemented as a snap-fit ​​combination or a snap-fit ​​structure that can be positioned and cooperate with each other.

[0040] Please see Figure 3In some embodiments, the splicing segment 210 may include a slide rail body 211 and a positioning rod 212. The slide rail body 211 is hollow, and the positioning rod 212 passes through the slide rail body 211 and is fixed relative to the slide rail body 211. One end of the positioning rod 212 protrudes from the slide rail body 211, and this protruding part is the first positioning part 2121. The other end of the positioning rod 212 is recessed relative to the end of the slide rail body 211, and this recessed part is the second positioning part 2122.

[0041] Specifically, through the interlocking of the first positioning part 2121 and the second positioning part 2122, when adjacent splicing segments 210 are connected, the first positioning part 2121 of the previous splicing segment 210 can be embedded into the second positioning part 2122 of the subsequent splicing segment 210, achieving rapid and precise docking of adjacent splicing segments 210. This also significantly reduces the assembly difficulty of the guide rail assembly 200 on the tower 100, saving time and labor costs for high-altitude installation. Furthermore, the placement of the positioning rod 212 through the slide rail body 211 facilitates rapid configuration of the first positioning part 2121 and the second positioning part 2122. Simultaneously, the positioning rod 212 further enhances the structural strength of the guide rail assembly 200, improves the overall connection rigidity of the guide rail assembly 200, and prevents loosening at the splicing points during long-term use.

[0042] Optionally, the positioning rod 212 may be made of high-strength alloy steel, which helps to improve tensile strength and effectively withstand the lateral impact force when the climber 300 slides, preventing bending deformation of the positioning rod 212 and ensuring the long-term stability of the guide rail assembly 200. After the positioning rod 212 passes through the hollow part, it can be fixed to the slide rail body 211 by welding or bolting, etc., without limitation. Preferably, the positioning rod 212 and the slide rail body 211 are fixed by full welding, which can eliminate the connection gap between the two and prevent fretting wear.

[0043] Please see Figure 4 In some embodiments, the slide rail body 211 may include a base 2111 and a sliding part 2112. The base 2111 is integrally formed with the first main material 111, and the sliding part 2112 is used for the climber 300 to slide and engage.

[0044] Specifically, the integrated molding design of the slide rail body 211 and the main material of the iron tower 100 completely eliminates the connection gap of traditional post-installed guide rails, avoids safety hazards caused by fretting wear and corrosion, and improves the reliability of the fall protection system.

[0045] Optionally, the base 2111 and the first main material 111 can be, but are not limited to, manufactured using a hot-rolled integral forming process, with no assembly gap between them. This process allows the base 2111 and the first main material 111 to form a uniform metallographic structure, avoiding stress concentration problems caused by welding or bolting connections, and improving the fatigue resistance of the overall structure.

[0046] Optionally, the sliding part 2112 and the base 2111 are an integral structure, which ensures the structural strength of the slide rail body 211.

[0047] Optionally, the hollow portion of the slide rail body 211 can be located at the sliding part 2112.

[0048] Please see Figure 4 In some embodiments, the cross-sectional shape of the sliding part 2112 may be configured as circular or elliptical, which can form a smooth sliding fit with the climber 300 and reduce the jamming phenomenon during the climbing process.

[0049] Additionally, please see Figure 1 and Figure 2 In some embodiments, the fall-prevention climbing system 10 may include a reinforcement member 400 for locking the base 2111 to the first main member 111. The reinforcement member 400 can further distribute the stress on the splicing section 210 of the guide rail assembly 200, avoid local stress concentration on the first main member 111 of the tower 100, and protect the original structure of the tower 100 from damage.

[0050] Optionally, the reinforcement 400 can be, but is not limited to, a high-strength fastening bolt or clamp, which can further lock the base 2111 to the first main member 111 to enhance connection stability.

[0051] Please see Figure 5 In some embodiments, the climber 300 may include a first slider 310, a second slider 320, a locking switch 330, and a self-locking mechanism 340. The first slider 310 and the second slider 320 are closable in a direction that allows them to approach or move away from each other, such that the first slider 310 and the second slider 320 can be slidably engaged or disengaged from the guide rail assembly 200. The locking switch 330 is used to lock or unlock the opening and closing movement between the first slider 310 and the second slider 320. The self-locking mechanism 340 is rotatably connected between the first slider 310 and the second slider 320, and the self-locking mechanism 340 can rotate relative to the first slider 310 and the second slider 320 until it abuts against and is confined within the guide rail assembly 200.

[0052] Specifically, the locking switch 330 can be a push-button type or a toggle type, and is located at the connection between the first slider 310 and the second slider 320. It is used to lock or unlock the opening and closing movement between the first slider 310 and the second slider 320. This facilitates the quick assembly and disassembly of the climber 300 on the guide rail assembly 200, allowing operators to work at different locations on the tower 100. Furthermore, the locking switch 330 prevents the climber 300 from accidentally opening or closing during normal climbing, improving safety.

[0053] It is worth noting that this application uses a locking switch 330 to lock or unlock the opening and closing movement between the first slider 310 and the second slider 320, so that the climber 300 can be disassembled and reinstalled at any position of the guide rail assembly 200 to achieve steering. This reduces the need for a steering mechanism on the guide rail assembly 200 for steering of the climber 300, as is done in conventional technology, and simplifies the structural layout.

[0054] Optionally, the self-locking mechanism 340 can be a ratchet-type limiting structure. The ratchet-type self-locking mechanism 340 can quickly abut against the guide rail assembly 200 and lock in place when the climber 300 accidentally slides, thus preventing the operator from falling.

[0055] In some embodiments, the climber 300 may include a speed-sensing self-locking module (not shown), which is connected to the self-locking mechanism 340. The speed-sensing self-locking module is used to sense the speed between the climber 300 and the guide rail assembly 200. When the speed reaches a preset value, the speed-sensing self-locking module is used to drive the self-locking mechanism 340 to abut against and limit the climber to the guide rail assembly 200.

[0056] Optionally, the speed-sensing self-locking module can have a built-in centrifugal speed sensor. When the speed reaches a preset value, the speed-sensing self-locking module can automatically drive the self-locking mechanism 340 to abut against and limit the guide rail assembly 200, thus realizing automatic sensing and locking of falls, and preventing the climber 300 from sliding down in the event of an accident, ensuring the safety of the workers.

[0057] In some embodiments, the climber 300 also includes a stop mechanism (not shown) for manual operation to abut and limit its position against the guide rail assembly 200. The operator can manually operate a lever to drive the stop mechanism to abut and limit its position against the guide rail assembly 200. This manual stop mechanism meets the operator's need to stay and work on the tower, manually locking the climber 300 to prevent slippage during operation and improving the stability of high-altitude work.

[0058] In some embodiments, the tower layer 110 is provided with a positioning mechanism (not shown), and two adjacent tower layers 110 are positioned and cooperated with each other through their respective mechanisms to be stacked, so as to realize the rapid and accurate assembly of the iron tower 100 and improve the overall assembly efficiency of the iron tower 100.

[0059] Optionally, the positioning mechanism can be a structure of positioning pins and positioning holes located at the four corners of the tower layer 110. Two adjacent tower layers 110 are positioned and engaged with each other through their respective positioning pins and positioning holes, achieving a stacked arrangement. During the overall assembly of the tower 100, the positioning pins of the lower tower layer 110 are first aligned with the positioning holes of the upper tower layer 110 to achieve precise alignment before welding or bolting, ensuring the connection accuracy between the tower layers 110. Furthermore, the positioning mechanism helps limit the relative displacement between the tower layers 110, improving the overall structural rigidity and stability of the tower 100. Simultaneously, the precise positioning of the positioning mechanism ensures the alignment accuracy of the splicing sections 210 of the guide rail assemblies 200, preventing misalignment.

[0060] In some embodiments, the fall-prevention climbing system 10 further includes a corrosion-resistant structure. Optionally, the surface of the guide rail assembly 200 may be entirely coated with a fluorocarbon coating, which has excellent weather resistance and corrosion resistance and can be used for a long time in salt spray environments without rusting.

[0061] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0062] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
