These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concepts of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0040] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses consistent with some aspects of this application as detailed in the appended claims.

[0041] Wind power equipment is used to convert wind energy into electrical energy. The tower is a crucial component of the wind power equipment's structure, and it has a relatively large diameter. During tower production, surface finishing work is required near the top of the horizontally placed tower. The tower has flanges at both ends, which are used to connect adjacent tower sections when the wind power equipment is erected.

[0042] For example, consider spraying markings on the surface of a tower. During the marking process, the tower should not be rotated or repositioned in the circumferential direction (either for the safety of the operator or to protect the marked area). When the marking is large, at least part of it will extend to the vicinity of the top of the horizontally placed tower. In this case, it is unavoidable that the operator needs to reach the vicinity of the top of the horizontally placed tower to perform the work.

[0043] It should be noted that during the process of spraying markings or surface repair work on the tower surface, in order to ensure the safety of the workers, the tower is fixed on a fixture (for example, the tower is placed on the fixture to be supported by the fixture, and the flange is fastened to the fixture by fasteners to fix the tower). The fixture is stably set on the ground (if necessary, a stable connection is formed between the tower and the ground by anchor bolts).

[0044] For example, surface work on the vicinity of the top of a horizontally placed tower can also be paint repair on the vicinity of the top of a horizontally placed tower.

[0045] In related technologies, workers either lean against a ladder on the tower or use a lift vehicle to perform surface work near the top of a horizontally placed tower.

[0046] However, the relevant technology is difficult to adapt to the curved surface of the tower, making it difficult for workers to safely access the outer wall near the top of the horizontally placed tower.

[0047] Understandably, when leaning a ladder against a horizontally placed tower, the ladder can easily scratch the surface of the tower, thereby damaging the protective layer that has been processed for corrosion prevention. Because the ladder is prone to sliding relative to the erection point, its safety is low. During the operation, it is also necessary to frequently change the erection position and ensure the stability of the ladder. Thus, using a ladder also reduces the efficiency of the operation.

[0048] For aerial work platforms, the position of the platform needs to be frequently adjusted during operation, as well as the relative position of the platform and the tower (ensuring that the platform is in a position that allows workers to easily access the tower while avoiding damage to the tower surface). This not only results in low work efficiency but also requires the arrangement of professional aerial work platform drivers.

[0049] To address the problem that workers cannot safely access the outer wall near the top of a horizontally placed tower, this application provides a tower fall prevention device.

[0050] This tower fall arrestor uses two connecting frames, a first connecting frame and a second connecting frame, to mount a step platform and a fall arrest rope on top of a horizontally placed tower. Workers can walk on the step platform on top of the tower, facilitating their access to the outer wall near the top. The fall arrest rope also provides additional safety protection against falls from the top of the tower, thus improving operational safety.

[0051] Compared to ladders, this tower fall arrestor has the following advantages: First, its relative position to the tower is fixed during use, which not only avoids scratches on the tower surface to protect it, but also avoids the overturning problem that exists with ladders, thus improving operational safety; Second, it eliminates the need for frequent adjustments to the installation position, thereby improving operational efficiency; Third, the bending characteristic of the tower surface no longer interferes with the operational requirement that "the worker touches the outer wall near the top of the horizontally placed tower".

[0052] Compared to a lifting platform, this tower fall arrestor has the following advantages: First, it eliminates the need for a lifting platform operator, saving labor costs; second, it eliminates the need for frequent adjustments to the erection position, improving work efficiency and avoiding collisions to the tower caused by frequent adjustments to the lifting platform's work platform, thus protecting the tower; third, the step platform is closer to the tower's surface than the lifting platform's work platform, making it easier for workers to access the outer wall near the top of the horizontally placed tower.

[0053] Reference Figure 1 and Figure 2 As shown in the figure, the tower fall arrestor provided in this application embodiment includes a connecting frame 100, a step platform 200, and a fall arrestor rope 300. The connecting frame 100 includes a first connecting frame 100a and a second connecting frame 100b.

[0054] A first connecting bracket 100a is detachably connected to a first end 11 of a tower 10, and is adapted to extend upward toward the tower 10 to which it is connected. A second connecting bracket 100b is detachably connected to a second end 12 of a tower 10, and is adapted to extend upward toward the tower 10 to which it is connected.

[0055] The step platform 200 is connected to the first connecting frame 100a and also to the second connecting frame 100b. The bottom of the step platform 200 is adapted to abut against the outer wall of the tower 10. It should be noted that the top of the step platform 200 is used for worker walking. For example, the bottom of the step platform 200 can be formed of a material that will not scratch the surface of the tower 10.

[0056] For example, the step platform 200 includes a step platform body, which can be formed as a grating panel. Alternatively, the step platform body can be formed as a steel frame and a cover plate covering the top of the steel frame; wherein the steel frame serves as structural support, and the cover plate is used to support workers walking on it.

[0057] The step platform 200 and the first connecting frame 100a can be detachably connected, for example, by means of fasteners; understandably, when the two are connected by fasteners, relative movement between them can be avoided; thus, when the tower fall arrestor is used, the step platform 200 can be prevented from overturning.

[0058] The step platform 200 and the second connecting frame 100b can be detachably connected, for example, by means of fasteners; understandably, when the two are connected by fasteners, relative movement between them can be avoided; thus, when the tower fall arrestor is used, the step platform 200 can be prevented from overturning.

[0059] In this embodiment, the fall arresting rope 300 is formed as a steel wire rope; in some possible embodiments, the fall arresting rope 300 may be formed as a non-metallic material.

[0060] The fall arrestor rope 300 is connected to a first connecting bracket 100a and a second connecting bracket 100b. Exemplarily, the first connecting bracket 100a and the second connecting bracket 100b may have rope loops for connecting the fall arrestor rope 300. The end of the fall arrestor rope 300 is adapted to pass through the corresponding rope loop and is secured by a wire rope clamp to firmly connect the fall arrestor rope 300 to the rope loop.

[0061] The fall arresting rope 300 can also be connected to a tensioning device, which is configured to adjust the tension of the fall arresting rope 300. The tensioning device can be configured as a basket catcher.

[0062] For example, the fall arrestor 300 is located above the step platform 200. This application does not limit the distance between the fall arrestor 300 and the step platform 200. The distance between the fall arrestor 300 and the step platform 200 can be between 1.05m and 1.2m, for example, 1.05m, 1.1m, 1.15m, or 1.2m. When the distance between the fall arrestor 300 and the step platform 200 is between 1.05m and 1.2m, the fall arrestor 300 can act as a guardrail for workers walking on the step platform 200; and it has a smaller height requirement for the connecting frame 100, which helps to lower the center of gravity of the tower fall arrestor.

[0063] Understandably, when the fall arrest rope 300 is configured to function as a guardrail, the projection of the fall arrest rope 300 on the step platform 200 is positioned near the edge of the step platform 200 so as not to affect the worker's walking on the step platform 200.

[0064] Of course, in some possible embodiments, the distance between the fall arrest rope 300 and the step platform 200 may be greater than the height of the worker; understandably, this is to avoid the fall arrest rope 300 affecting the worker's walking path on the step platform 200.

[0065] It should be noted that the fall arrestor rope 300 is used to provide a suspension position for the load-bearing hook of the fall arrestor safety belt worn by the worker. In addition, the tension provided by the fall arrestor rope 300 also has the function of tightening the first connecting frame 100a and the second connecting frame 100b connected to the tower 10, so as to improve the stability of the first connecting frame 100a and the second connecting frame 100b connected to the tower 10.

[0066] This application does not limit the number of fall arresting ropes 300; the number of fall arresting ropes 300 can be one or multiple. It is understood that when the number of fall arresting ropes 300 is multiple...

[0067] It should be noted that during the surface work of the tower 10, the horizontally placed tower 10 will be fixed by a fixture. The tower is fixed to the fixture (for example, the tower is placed on the fixture to be supported by the fixture, and the flange is fastened to the fixture by fasteners to fix the tower), and the fixture is stably set on the ground (if necessary, a stable connection is formed between the tower and the ground by anchor bolts).

[0068] The tower fall arrestor provided in this application embodiment uses two connecting frames 100 (first connecting frame 100a and second connecting frame 100b) to mount a step platform 200 and a fall arrestor rope 300 on the top of a horizontally placed tower 10. Workers can walk on the top of the horizontally placed tower 10 via the step platform 200, thus facilitating access to the outer wall near the top of the horizontally placed tower 10. Workers can also use the fall arrestor rope 300 for fall protection, preventing falls from the top of the tower 10 and improving operational safety.

[0069] Compared to ladders, this tower fall arrestor has the following advantages: First, its relative position to the tower 10 is fixed during use, which not only avoids scratches on the surface of the tower 10, thus protecting the tower 10, but also avoids the overturning problem that exists with ladders, thereby improving operational safety; Second, it eliminates the need for frequent adjustments to the installation position, thus improving operational efficiency; Third, the bending feature of the tower 10 surface no longer interferes with the operational requirement that "the operator touches the outer wall near the top of the horizontally placed tower 10".

[0070] Compared to the lifting vehicle, the tower fall arrestor has the following advantages: First, it does not require a lifting vehicle operator, thus saving labor costs; second, it eliminates the need for frequent adjustments to the erection position, improving work efficiency and avoiding collisions to the tower caused by frequent adjustments to the lifting vehicle's work platform, thus protecting the tower; third, the step platform 200 is closer to the surface of the tower 10 than the lifting vehicle's work platform, making it easier for workers to access the outer wall near the top of the horizontally placed tower 10.

[0071] It should be noted that when the operator is working on the outer wall near the top of the tower 10 while on the tower fall arrestor, the operator can squat, bend over, or sit on the step platform 200.

[0072] It should be noted that when marking or partially repairing the tower 10, the step platform 200 should be erected in a position that does not obscure the markings or the area to be worked on.

[0073] Reference Figure 1 and Figure 2 As shown, in some embodiments, the tower 10 includes a flange 13, and a connecting frame 100 is adapted to be detachably connected to the flange 13. In this embodiment, the connecting frame 100 is adapted to be connected to the flange 13, thus improving the ease of detachable connection between the tower fall arrestor and the tower 10 by utilizing the existing structure of the flange 13 of the tower 10 itself, and also enhancing the compatibility of the tower fall arrestor with towers 10 of different diameters.

[0074] It should be noted that the first connecting bracket 100a is adapted to be detachably connected to the flange 13 located at the first end 11; the second connecting bracket 100b is adapted to be detachably connected to the flange 13 located at the second end 12.

[0075] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, the tower fall arrestor further includes a first fastener 410, through which the connecting frame 100 and the flange 13 are detachably connected. The connecting frame 100 has a first through hole 101, which is adapted to allow the first fastener 410 to pass through. The first through hole 101 is formed as an elongated hole. In this embodiment, the first through hole 101 is formed as an elongated hole; this facilitates, on the one hand, adjusting the position of the first fastener 410 relative to the connecting frame 100, so as to align the first fastener 410 with the corresponding hole on the flange 13, so that the connecting frame 100 can be adapted to be connected to flanges 13 of different sizes, thereby improving the compatibility of the tower fall arrestor; on the other hand, it allows multiple first fasteners 410 to pass through the first through hole 101, so as to improve the firmness of the connection between the connecting frame 100 and the flange 13 through multiple fasteners.

[0076] For example, the first fastener 410 includes a bolt and a mating nut. The nut may be configured as a lock-lock nut; or, the first fastener 410 may further include a washer for preventing the corresponding nut from loosening.

[0077] For example, the number of first perforations 101 can be one, two, or more.

[0078] Reference Figure 1 , Figure 2 and Figure 5 As shown, in some embodiments, the tower fall arrestor further includes a first reinforcing rod 500. The first reinforcing rod 500 is detachably connected to the flange 13 and also detachably connected to the connecting frame 100. The first reinforcing rod 500 is inclined relative to the connecting frame 100. In this embodiment, the first reinforcing rod 500 provides support for the connecting frame 100. The first reinforcing rod 500, the corresponding portion of the connecting frame 100, and the corresponding portion of the flange 13 form a triangular structure (which can be called a first type of triangle). This helps to further improve the firmness of the connection between the connecting frame 100 and the corresponding flange 13, thereby improving the safety performance of the tower fall arrestor.

[0079] It should be noted that the first connecting frame 100a is equipped with a corresponding first reinforcing rod 500, and the second connecting frame 100b is equipped with another first reinforcing rod 500.

[0080] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, in some embodiments, the tower fall arrestor further includes a second reinforcing rod 600. The second reinforcing rod 600 is detachably connected to the flange 13 and also detachably connected to the connecting frame 100. The second reinforcing rod 600 is inclined relative to the connecting frame 100. The ends of the first reinforcing rod 500 and the second reinforcing rod 600 located away from the connecting frame 100 are connected to the flange 13 on both sides of the connecting frame 100.

[0081] In this embodiment, the second reinforcing rod 600 provides further support to the connecting frame 100. The second reinforcing rod 600, the corresponding part of the connecting frame 100, and the corresponding part of the flange 13 form another triangular structure (which can be called a second type of triangle). This helps to further improve the firmness of the connection between the connecting frame 100 and the corresponding flange 13, thereby improving the safety performance of the tower fall arrest device.

[0082] It should be noted that the first connecting frame 100a is equipped with a corresponding second reinforcing rod 600, and the second connecting frame 100b is equipped with another second reinforcing rod 600.

[0083] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, in some embodiments, the tower fall arrestor further includes a second fastener 420. The connecting frame 100 has a second through hole 102, the first reinforcing rod 500 has a third through hole 501, and the second reinforcing rod 600 has a fourth through hole 601. The second fastener 420 is adapted to pass through the second through hole 102, the third through hole 501, and the fourth through hole 601, and the second fastener 420 securely connects the first reinforcing rod 500, the second reinforcing rod 600, and the connecting frame 100.

[0084] In this embodiment, the first reinforcing rod 500 and the second reinforcing rod 600 are detachably connected to the connecting frame 100 via the second fastener 420. This facilitates the disassembly and assembly of the first reinforcing rod 500, the second reinforcing rod 600, and the connecting frame 100. Furthermore, the first reinforcing rod 500, the second reinforcing rod 600, and the corresponding flange 13 form another triangular structure (which can be called a third type of triangle). The area of ​​the third type of triangle is larger than the areas of the first and second types of triangles. This further enhances the stability of the support for the connecting frame 100, thereby further improving the safety performance of the tower fall arrestor.

[0085] For example, the second fastener 420 includes a bolt and a mating nut. The nut may be configured as a lock-lock nut; or, the second fastener 420 may further include a washer for preventing the corresponding nut from loosening.

[0086] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, in some embodiments, the tower fall arrestor may further include a third fastener 430 and a fourth fastener 440. The first reinforcing rod 500 and the flange 13 are detachably connected via the third fastener 430. The first reinforcing rod 500 has a fifth through hole 502 adapted to accommodate the third fastener 430. The second reinforcing rod 600 and the flange 13 are detachably connected via the fourth fastener 440. The second reinforcing rod 600 has a sixth through hole 602 adapted to accommodate the fourth fastener 440.

[0087] In this embodiment, the first reinforcing rod 500 can be connected to the flange 13 through the existing bolt holes of the flange 13 via the third fastener 430; the second reinforcing rod 600 can be connected to the flange 13 through the existing bolt holes of the fourth fastener 440. This facilitates the connection of the first reinforcing rod 500 on the tower 10, thereby improving the ease of installation of the tower fall arrestor on the tower.

[0088] For example, the third fastener 430 includes a bolt and a mating nut. The nut may be configured as a lock nut; or, the third fastener 430 may further include a washer for preventing the corresponding nut from loosening.

[0089] The fourth fastener 440 includes a bolt and a mating nut. The nut may be configured as a lock nut; or, the fourth fastener 440 may further include a washer for preventing the corresponding nut from loosening.

[0090] For example, the tower fall arrestor may further include a pad 700 having a seventh through hole 710. The seventh through hole 710 is adapted to accommodate a third fastener 430 or a fourth fastener 440. Corresponding pads 700 are provided between the first reinforcing rod 500 and the flange 13, and between the second reinforcing rod 600 and the flange 13, respectively, so that the first reinforcing rod 500 is securely fastened to the flange 13 by the third fastener 430, and the second reinforcing rod 600 is securely fastened to the flange 13 by the fourth fastener 440. This improves the stability of the tower fall arrestor installation and enhances its safety.

[0091] Reference Figure 1 , Figure 9 and Figure 10 As shown, in some embodiments, the step platform 200 includes a step platform body 210, a support body 220, and a cushioning pad 230. The number of support bodies 220 is multiple. The step platform body 210 is suitable for workers to step on. The support body 220 is adapted to extend towards the tower 10; the cushioning pad 230 is provided at the end of the support body 220 facing the tower 10, and the cushioning pad 230 is adapted to abut against the outer wall of the tower 10.

[0092] In this embodiment, the step platform 200 reduces the contact area with the surface of the tower 10 through multiple supports 220, which helps protect the surface of the tower 10; and it contacts the surface of the tower 10 through a buffer pad 230 to prevent the supports 220 from scratching the surface of the tower 10. Thus, when in use, the tower fall arrestor not only stably supports the step platform 200 on the tower 10 to further improve operational safety, but also effectively protects the surface of the tower 10.

[0093] For example, the step platform body 210 can be formed as a grating panel. Alternatively, the step platform body can be formed as a steel frame and a cover plate (e.g., a steel plate) covering the top of the steel frame; wherein the steel frame serves as structural support and the cover plate is used to support the workers walking on it.

[0094] For example, the cushioning pad 230 can be formed of rubber. The support body 220 can be formed of steel. The cushioning pad 230 can be connected to the corresponding support body 220 by adhesive.

[0095] Reference Figure 10 As shown, in some embodiments, the upper surface of the step platform body 210 is provided with anti-slip texture 211. The anti-slip texture 211 is used to prevent workers from slipping when walking on the step platform body 210.

[0096] For example, the main body of the step platform is formed as a steel frame and a cover plate covering the top of the steel frame. When the cover plate is formed as a steel plate, the anti-slip texture 211 can be a protrusion formed on the surface of the steel plate (e.g., a protrusion formed by stamping). When the cover plate is formed as a steel plate, the anti-slip texture 211 can be formed as a rib fixed to the surface of the cover plate.

[0097] Reference Figure 1 , Figure 3 , Figure 4 , Figure 8 and Figure 9As shown, in some embodiments, the connecting frame 100 includes a connecting frame body 110 and an overlapping platform 120. The connecting frame body 110 is adapted to extend upward toward the tower 10. The overlapping platform 120 is disposed on the side of the connecting frame body 110 facing the step platform body 210. The overlapping platform 120 has a limiting groove 121; the step platform 200 also includes a snap-fit ​​body 240, which is disposed on the step platform body 210; the limiting groove 121 is adapted to insert the snap-fit ​​body 240 and limit the snap-fit ​​body 240 in the horizontal direction.

[0098] In this embodiment, the step platform 210 can be connected to the corresponding connecting frame 100 via the overlapping platform 120 and the snap-fit ​​body 240. This improves the ease of erecting or dismantling the step platform 200 on the tower 10, thereby enhancing the convenience of using the tower fall protection device. Simultaneously, the limiting groove 121 prevents the step platform 210 from detaching from the connecting frame 100, and the weight of the step platform 200 itself prevents it from overturning, thus improving operational safety.

[0099] For example, in this embodiment, a limiting member can protrude from the connecting frame 100 toward the side of the step platform body 210, and this limiting member is located on the upper side of the step platform body 210. This limiting member can be a protrusion formed on the step platform body 210, or it can be a fastener detachably connected to the step platform body 210. It is understood that this limiting member can limit the vertical movement of the erected step platform 200, further preventing the overlapping step platforms 200 from overturning, thereby further enhancing the safety of the tower fall arrestor.
