[0002] Transmission towers are tower structures that support overhead conductors, lightning protection wires, and other accessories, and are an important component of overhead transmission lines. Because towers, conductors, and fittings are exposed to the outdoors for extended periods, the surrounding environment can cause defects or malfunctions in these components, requiring maintenance personnel to climb the towers to eliminate these problems. Currently, the primary method for climbing towers is using foot spikes attached to the tower.

[0003] In related technologies, operators may fall while climbing foot spikes. Utility Model Content

[0013] In some embodiments, the height of the fixing portion gradually decreases along the direction of the protrusion toward the fixing hole.

[0014] In some embodiments, the curved portion has a transition section, a connecting section, a first straight segment, and a second straight segment. The two ends of the transition section are respectively connected to the connecting portion and the first straight segment. The first straight segment and the second straight segment are arranged parallel to each other and spaced apart. The two ends of the connecting section are respectively connected to the first straight segment and the second straight segment. The connecting segment is located on the side of the fastener away from the transition section. The fastener is connected to at least one of the first straight segment and the second straight segment.

[0035] In this technology, operators need to climb the tower structure using climbing spikes to perform maintenance on power facilities. At higher heights, strong winds can cause them to lose their balance. If the hooks malfunction, a fall could occur.

[0036] In this embodiment, the fixing member 200 is provided to cooperate with the foot hook 300, thereby providing an additional connection between the operator and the climbing foot spikes, which can reduce the possibility of the operator falling.

[0037] This application provides a climbing spike; please refer to [link / reference]. Figure 1 and Figure 2The climbing spikes include a connector 100 and a fixing member 200. The connector 100 has a connecting portion 100a and a bent portion 100b. One end of the connecting portion 100a is used to connect to steel, and the other end of the connecting portion 100a is connected to the bent portion 100b, which is ring-shaped. The fixing member 200 is connected to the bent portion 100b and has a fixing hole 200a for inserting a foot hook 300 to engage with the fixing member 200.

[0038] The steel material refers to the steel material of the tower structure. The connecting part 100a can be inserted into the steel material and then fixed by nuts located on both sides of the steel material so that the connecting part 100 and the steel material remain fixed.

[0039] For example, the connector 100 is a structure formed by bending round steel multiple times, and the connector 100 is basically on the same plane.

[0040] For example, the fastener 200 is connected to the annular interior formed by the bending of the bend 100b.

[0041] For example, the fastener 200 is welded to the bend 100b, thereby increasing the connection strength between the fastener 200 and the connector 100.

[0042] It is understood that the embodiments of this application do not limit the shape of the ring formed by the bent portion 100b. The bent portion 100b can be bent to form a rectangle or a circle.

[0043] In this embodiment of the application, the climbing spikes include a connector 100 and a fixing member 200 connected to each other. A fixing hole 200a is used for a foot hook 300 to pass through, so that the foot hook 300 engages with the fixing member 200. The fixing member 200 increases the connection strength between the operator and the climbing spikes. After engaging the foot hook 300 with the fixing member 200, the operator can only detach the foot hook 300 from the fixing member 200 through a specific posture. The foot hook 300 is difficult to detach from the fixing member 200, thereby reducing the possibility of the operator falling while climbing the spikes.

[0044] In one embodiment, please refer to Figure 2 The fastener 200 has a bearing surface 200b, which is used to support the operator and is arranged along the horizontal plane.

[0045] For example, a fixing hole 200a is formed on the bearing surface 200b.

[0046] In the embodiment of this application, the bearing surface 200b is arranged along the horizontal plane so that when the operator steps on the fixing member 200, the supporting force exerted by the fixing member 200 on the operator is basically vertically upward, and the operator can maintain balance better, thereby further reducing the possibility of the operator falling.

[0047] It is understood that the embodiments of this application do not limit the arrangement direction of the bearing surface 200b. Exemplarily, the bearing surface 200b can be arranged at an angle to the horizontal plane.

[0048] In one embodiment, the thickness of the fastener 200 ranges from 2 mm to 3 mm.

[0049] For example, the thickness of the fastener 200 is 2.0 mm, 2.2 mm, 2.4 mm, 2.6 mm, 2.8 mm or 3.0 mm.

[0050] Understandably, the thickness of the fastener 200 can be measured using a ruler or vernier caliper under normal temperature and pressure conditions.

[0051] In the embodiments of this application, the thickness of the fastener 200 is within a suitable range, which can balance the high strength of the fastener 200 with the low manufacturing cost of the climbing spikes.

[0052] In one embodiment, please refer to Figure 1 There are multiple fixing holes 200a, and the multiple fixing holes 200a are arranged at intervals along the arrangement direction of the connector 100 and the fixing member 200.

[0053] For example, when projected along the thickness direction of the fastener 200, the shape of the fixing hole 200a is approximately trapezoidal, which makes it easy for the operator to align and insert the foot hook 300 into the fixing hole 200a.

[0054] In the embodiment of this application, there are multiple fixing holes 200a. During the climbing process, the operator can align the foot hook 300 with any of the fixing members 200 to achieve engagement. The multiple fixing holes 200a can accommodate various climbing postures, allowing the operator to select a suitable fixing hole 200a during climbing to align the foot hook 300 with the fixing hole 200a.

[0055] It is understood that the embodiments of this application do not limit the number of fixing holes 200a. Exemplarily, the number of fixing holes 200a may be one, two, or three.

[0056] In one embodiment, please refer to Figure 1 and Figure 2The fastener 200 also has a protrusion 200c, which extends along the arrangement direction of the connector 100 and the fastener 200. The protrusion 200c is located behind the fixing hole 200a and protrudes upward along the height direction.

[0057] For example, the protrusion 200c and the fixing hole 200a are arranged orthogonally to the arrangement direction of the connector 100 and the fixing member 200.

[0058] In this embodiment of the application, the fixing member 200 further has a protrusion 200c that protrudes along the height direction, and the protrusion 200c is located behind the fixing hole 200a. During the operator's climbing of the climbing spikes, the foot hook 300 located on the operator's foot passes through the fixing hole 200a. The protrusion 200c located behind the fixing hole 200a can support the operator's shoe sole, thereby increasing the contact area between the shoe sole and the climbing spikes, increasing the friction between the shoe sole and the climbing spikes, and also improving the operator's comfort.

[0059] It is understood that the embodiments of this application do not limit whether the fastener 200 has a protrusion 200c.

[0060] In one embodiment, please refer to Figure 2 Along the direction from the protrusion 200c toward the fixing hole 200a, the height of the fixing part gradually decreases.

[0061] For example, the protrusion 200c and the fixing hole 200a are arranged in the front-back direction.

[0062] For example, the front-back direction is as follows Figure 1 The direction indicated by the middle arrow R1.

[0063] In the embodiment of this application, the height of the protrusion 200c gradually decreases along the direction toward the fixing hole 200a, and the shape of the protrusion 200c can fit the sole of the operator's shoe more closely, thereby further improving the operator's comfort during the climbing process.

[0064] It is understood that the embodiments of this application do not limit the shape of the protrusion 200c. Exemplarily, the height of the protrusion 200c remains constant in the direction toward the fixing hole 200a.

[0065] In one embodiment, please refer to Figure 1The curved portion 100b has a transition section 110, a connecting section 120, a first straight section 130, and a second straight section 140. The two ends of the transition section 110 are connected to the connecting portion 100a and the first straight section 130, respectively. The first straight section 130 and the second straight section 140 are arranged parallel to each other and spaced apart. The two ends of the connecting section 120 are connected to the first straight section 130 and the second straight section 140, respectively. The connecting section 120 is located on the side of the fastener 200 away from the transition section 110. The fastener 200 is connected to at least one of the first straight section 130 and the second straight section 140.

[0066] For example, the transition section 110, the connecting section 120, the first straight section 130 and the second straight section 140 are all formed by hot bending of round steel.

[0067] For example, the outer surfaces of the first straight segment 130 and the second straight segment 140 have anti-slip textures 130a, which can increase the friction between the operator's shoe sole and the climbing spikes.

[0068] For example, the transition section 110 and the first straight section 130, the first straight section 130 and the connecting section 120 and the connecting section 120 and the second straight section 140 are connected by arc transitions, thereby reducing the occurrence of stress concentration in the connector 100.

[0069] For example, the fastener 200 is connected to the first straight segment 130 and the second straight segment 140 respectively.

[0070] In the embodiment of this application, the curved portion 100b has a transition section 110, a connecting section 120, a first straight section 130, and a second straight section 140. The first straight section 130 and the second straight section 140 can increase the connection strength between the fixing member 200 and the connecting member 100, thereby making the fixing member 200 more stable during the load-bearing process and the climbing spikes have higher safety.

[0071] It is understood that the embodiments of this application do not limit the shape of the bent portion 100b. Exemplarily, the bent portion 100b can be bent in a circular shape.

[0072] In one embodiment, please refer to Figure 1 The fastener 200 and the connecting section 120 are arranged at intervals, and the fastener 200, the first straight section 130, the second straight section 140 and the connecting section 120 form a cavity 100c.

[0073] In this embodiment of the application, the fixing member 200, the first straight segment 130, the second straight segment 140, and the connecting segment 120 form a cavity 100c. During the climbing process, the operator can attach the hook worn on their body to the cavity 100c of the climbing spike above, thereby adding an extra layer of protection. Furthermore, the cavity 100c formed by the fixing member 200, the first straight segment 130, the second straight segment 140, and the connecting segment 120 allows the hook to be kept as far away as possible from the opening of the climbing spike, thereby reducing the possibility of the hook detaching from the climbing spike.

[0074] The embodiments of this application are not limited to the arrangement of the fastener 200 and the connecting segment 120 at intervals. Exemplarily, the fastener 200 and the connecting segment 120 are fitted together.

[0075] In one embodiment, please refer to Figure 1 The fastener 200 also has a curved section 150, one end of which is connected to the second straight section 140, and the other end of which extends toward the transition section 110.

[0076] In the embodiment of this application, the fixing member 200 further has a curved section 150, one end of which extends toward the transition section 110. The curved section 150 extends toward the transition section 110, allowing the operator to attach the hook to the curved section 150 during climbing, thereby reducing the risk of falling. Furthermore, the curved section 150 and the transition section 110 reduce the risk of the hook detaching from the climbing spikes.

[0077] In one embodiment, the distance between the end of the curved section 150 facing the transition section 110 and the transition section 110 is less than or equal to 0.2 mm.

[0078] The distance between the end of the curved section 150 facing the transition section 110 and the transition section 110 refers to the shortest distance between the end of the curved section 150 facing the transition section 110 and the transition section 110.

[0079] For example, the distance between the end of the curved section 150 facing the transition section 110 and the transition section 110 is 0 mm, 0.05 mm, 0.10 mm, 0.15 mm or 0.20 mm.

[0080] Understandably, the distance between the end of the curved section 150 facing the transition section 110 and the transition section 110 can be obtained by measuring with vernier calipers under normal temperature and pressure.

[0081] For example, when the distance between the end of the bent section 150 facing the transition section 110 and the transition section 110 is 0 mm, the bent section 150 and the transition section 110 are welded together.

[0082] In the embodiment of this application, the smaller distance between the end of the curved section 150 facing the transition section 110 and the transition section 110 can reduce the possibility of the hook detaching from the gap between the curved section 150 and the transition section 110 to a certain extent, thereby reducing the risk of the operator falling.

[0083] It is understood that the embodiments of this application do not limit the size of the gap between the curved section 150 and the transition section 110.

[0084] Embodiments of this application also provide a foot spike assembly, which includes climbing spikes and a foot hook 300. At least a portion of the structure of the foot hook 300 is bent to form a hook portion 300a, which can pass through a fixing hole 200a to engage the foot hook 300 with a fixing member 200. The foot hook 300 also has a mounting portion 300b for mounting to the sole of a shoe.

[0085] Understandably, the soles of the safety shoes worn by operators are usually equipped with metal plates, and the mounting part 300b can be detachably connected to the sole via a threaded connection.

[0086] For example, the foot hook 300 is partially bent forward to form a hook portion 300a. During climbing, the operator typically faces the tower structure, and there is a risk of falling backward. The hook portion 300a, bent forward, can engage with the climbing spikes in case the operator tends to fall backward, thus providing some support.

[0087] The above embodiments are merely illustrative of the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. These modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application, and all should be covered within the scope of the specification of this application. In particular, as long as there is no structural conflict, the various technical features mentioned in the embodiments can be combined in any way. This application is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of protection.
