[0027] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0028] Referring to Figures 1 to 4 The embodiment of the first aspect of the present application discloses an anti-falling device, which comprises a spike and a fastening assembly.

[0029] Specifically, the spike comprises a fastening segment 110 and a closed annular body 120. The fastening segment 110 is used to penetrate the installation hole. The fastening segment 110 is provided with a first threaded segment and a second threaded segment. The annular body 120 is connected with the fastening segment 110. The annular body 120 is formed with a support surface 127 and a connecting hole 126. The fastening assembly comprises a first nut 210 and a second nut 220. The first nut 210 is threadedly connected with the first threaded segment. The second nut 220 is threadedly connected with the second threaded segment.

[0030] In the anti-falling device provided by the embodiment of the present application, the annular body 120 is formed with the support surface 127 and the connecting hole 126. The support surface 127 can provide a support point for the tower climbing worker, facilitating the worker to climb the power transmission tower. The connecting hole 126 can be connected and fixed with the hanging ring of the safety belt. In the embodiment of the present application, compared with the traditional one-word spike, the support surface 127 formed by the annular body 120 has a larger support surface 127, which can enhance the standing stability of the worker, reduce the physical consumption, and be beneficial to improve the working efficiency and safety.

[0031] Meanwhile, the annular main body 120 is formed with a closed connecting hole 126, when the hanging ring of the safety belt of the operator is connected with the connecting hole 126, the hidden danger that the hanging ring slides out of the connecting hole 126 can be eliminated, the reliable connection of the safety belt and the anti-falling device is ensured, the situations such as wrong hanging or ring falling are avoided, and the safety of the operation is improved.

[0032] In some embodiments of the present application, the rotation direction of the first threaded section is opposite to the rotation direction of the second threaded section. In this way, the loosening of the first nut 210 and / or the second nut 220 due to vibration can be effectively reduced, and the connection reliability of the anti-falling device and the power transmission tower can be ensured.

[0033] In some embodiments of the present application, the first nut 210 has two. Specifically, the first threaded section is located on the side of the mounting hole away from the annular main body 120, and the two first nuts 210 are respectively threadedly connected with different positions of the first threaded section. By providing two first nuts 210 on the first threaded section, the probability of loosening of the first nut 210 due to vibration is further reduced, and the stable connection of the anti-falling device and the power transmission tower is facilitated.

[0034] In the embodiment, referring to Figures 1 to 3 , the fastening assembly includes a third nut 230 and a gasket 240, the third nut 230 is threadedly connected with the first threaded section, and the third nut 230 is located at the end of the fastening section 110 away from the mounting hole; the gasket 240 is arranged between the third nut 230 and the first nut 210. The third nut 230 can effectively prevent the first nut 210 from loosening, so as to stably connect the anti-falling device and the angle steel plate 1.

[0035] In some embodiments of the present application, referring to Figures 1 to 3 , the annular main body 120 includes a first support section 121, an elevation section 122, a second support section 123 and a connecting section 124 arranged in a ring shape, the first support section 121 and the second support section 123 are arranged at intervals, the first support section 121 and the second support section 123 form a support surface 127, the elevation section 122 is arranged upwardly inclined relative to the support surface 127, and the elevation section 122 is located on the side of the annular main body 120 away from the fastening section 110, one end of the connecting section 124 is connected with one end of the second support section 123, and the other end of the connecting section 124 is connected with the first support section 121.

[0036] In a possible implementation, please continue to refer to Figures 1 to 3, the first support section 121 and the second support section 123 are arranged in parallel and spaced apart, and upper ends of the first support section 121 and the second support section 123 form a support surface 127, which can provide support for the worker. In actual application, the support surface 127 is parallel to the horizontal plane, so that the risk of slipping feet during the climbing process of the worker can be reduced. The arrangement of the inclined section 122 can reduce the risk of the worker's feet slipping out of the support surface 127 when stepping on the support surface 127.

[0037] In the embodiment, referring to Figures 1 to 3 , the first support section 121 is coaxially arranged with the fastening section 110, that is, the first support section 121 is directly fixedly connected with the mounting hole through the fastening section 110. In actual application, the first support section 121 is used to contact the heel of the worker, and the second support section 123 is used to contact the toe of the worker. In this way, most of the weight of the worker can be directly transmitted to the angle steel plate 1, the connection reliability of the anti-falling device and the angle steel plate 1 can be improved, and the safety of the anti-falling device is further improved.

[0038] It is worth understanding that, referring to Figure 1 and Figure 3 , the included angle between the inclined section 122 and the support surface 127 is θ.

[0039] In some embodiments of the present application, the included angle between the inclined section 122 and the support surface 127 ranges from 20° to 30°. When the included angle between the inclined section 122 and the support surface 127 is in the range of 20° to 30°, the function of preventing the worker's feet from slipping out of the support surface 127 can be maximized. If the included angle is less than 20°, the blocking effect of the inclined section 122 is not obvious enough to effectively prevent the feet from slipping out. If the included angle is greater than 30°, the worker will feel uncomfortable when stepping on the support surface 127, increasing the difficulty and physical exertion of climbing.

[0040] In some embodiments of the present application, the length ratio of the first support section 121 to the inclined section 122 is 4:1. By reasonably setting the length ratio of the first support section 121 to the inclined section 122 as 4:1, it can ensure that the inclined section 122 has sufficient length to play a blocking role to prevent the worker's feet from slipping out of the support surface 127, and it will not affect the normal stepping and climbing of the worker on the support surface 127 due to the too long inclined section 122, so that the entire anti-falling device can ensure safety while taking into account the convenience and comfort of use.

[0041] It is worth understanding that the length of the inclined section 122 refers to the length of the inclined section 122 in the inclined direction, denoted by L, as shown in Figure 3 .

[0042] In some embodiments of the present application, referring to Figures 1 to 3The elevation section 122 is arranged in a circular arc shape, so as to reduce the occurrence of sharp areas and help ensure the safety of the operating personnel.

[0043] Further, the connecting section 124 is arranged in a circular arc shape, further avoiding the occurrence of sharp areas to ensure the safety of the operating personnel.

[0044] In some embodiments of the present application, the fastening section 110 is integrally formed with the annular body 120. The integrally formed structure makes the overall strength of the cleat higher, avoids safety hazards caused by loose or broken connection parts, and can better withstand the stepping and external impact of the operating personnel, providing more reliable support for high-altitude work. At the same time, the integrally formed process simplifies the production process, reduces the processing and assembly links of parts, not only improves the production efficiency, but also reduces the production cost, and helps to ensure the stability and consistency of product quality.

[0045] In some embodiments of the present application, the connecting section 124 is at least partially welded to the first support section 121. The welding position is the welding portion 125. The welding portion further enhances the connection strength between the connecting section 124 and the first support section 121, so that the annular body 120 is not prone to deformation or breakage at the connection part when subjected to the stepping and external force of the operating personnel, thereby improving the overall stability and safety of the anti-falling device.

[0046] It is worth understanding that the welding portion can be precisely welded according to actual needs, which can ensure the connection strength without causing unnecessary heat effect on other parts, and helps to maintain the overall performance and quality of the cleat.

[0047] In some embodiments of the present application, the surface of the annular body 120 is provided with anti-slip lines 128. The anti-slip lines 128 can increase the friction between the operating personnel's feet and the support surface 127, reducing the risk of slipping, especially in wet or oily environments, the effect of the anti-slip lines 128 is more obvious.

[0048] It can be understood that the design of the anti-slip lines 128 can be diversified according to actual needs, such as using different shapes such as stripes, grids or dots to achieve the best anti-slip effect. At the same time, the depth and spacing of the anti-slip lines 128 also need to be reasonably set. Too deep or too dense lines may affect the stepping comfort of the operating personnel, while too shallow or too sparse lines may not provide enough anti-slip performance.

[0049] The embodiments of the second aspect of the present application disclose a power transmission tower, which comprises an angle steel plate 1 and an anti-falling device as described above. The angle steel plate 1 is provided with a mounting hole, the fastening section 110 is arranged through the mounting hole, the first nut 210 is located on one side of the mounting hole, and the second nut 220 is located on the other side of the mounting hole.

[0050] In practical applications, the power transmission tower is connected with the fastening segment 110 of the anti-falling device through the mounting hole on the angle steel plate 1, realizing stable connection. The first nut 210 and the second nut 220 are respectively located on both sides of the mounting hole, and are threadedly connected with the first threaded segment and the second threaded segment on the fastening segment 110, thereby firmly fixing the anti-falling device on the angle steel plate 1. This connection mode is not only simple and reliable, but also facilitates installation and disassembly, greatly improving the maintenance efficiency of the power transmission tower. At the same time, since the annular main body 120 of the anti-falling device forms the support surface 127 and the connecting hole 126, the operating personnel can obtain more stable support when climbing the power transmission tower, reducing physical exertion and improving operating efficiency and safety. In addition, when the safety belt hanging ring of the operating personnel is connected with the connecting hole 126, it can ensure that the safety belt is reliably connected with the anti-falling device, avoiding situations such as wrong hanging or ring disconnection, further improving the safety of the operation.
