Description

Technical Field

[0001] This utility model relates to the field of tower sign installation technology, and in particular to a sign iron component and sign assembly for power towers. Background Technology

[0002] Signage on power transmission towers is a crucial facility for ensuring the safe operation of the power grid and public safety, serving a warning function. During installation, signs are typically secured to the towers using a combination of hoisting, welding, or bolting. However, prolonged exposure to sun and rain inevitably leads to discoloration and corrosion, necessitating timely disassembly and maintenance. Unfortunately, the disassembly and installation of these signs often require significant manpower and resources, are extremely inconvenient, and result in difficult replacements and high maintenance costs. Therefore, the existing signage structure needs further optimization. Utility Model Content

[0003] This utility model aims to solve at least one of the technical problems existing in the prior art. To this end, this utility model proposes a sign iron component and sign assembly for power towers, which is easy to assemble and disassemble, easy to replace, and has low maintenance costs.

[0004] The first aspect of this utility model provides a steel sign component for a power tower, comprising:

[0005] The first support rod extends vertically;

[0006] A support assembly extending in a first direction, wherein two support assemblies are provided and are symmetrically arranged in the vertical direction about the first support rod, one end of each of the two support assemblies is connected to the upper end and the lower end of the first support rod respectively, and one end of each support assembly is configured to rotate relative to the first support rod about a rotation axis extending in a second direction.

[0007] The second support rod extends vertically and is detachably connected to the other end of the two support assemblies, so that the first support rod, the two support assemblies and the second support rod together form a square opening for mounting the sign.

[0008] The first and second support poles are provided with mounting parts for detachable connection with the power tower. The signboard includes multiple signboards spliced ​​together along a first direction. The upper and lower ends of the signboards are provided with connecting parts. The support assembly is configured to be slidably and detachably connected with the connecting parts along the first direction. The first and second support poles are configured to abut against the corresponding signboards. The first direction, the second direction, and the up and down direction are perpendicular to each other.

[0009] The signage iron component of the power tower according to the first aspect of the present invention has at least the following beneficial effects: Since the two support components are arranged symmetrically about the first support rod and can rotate relative to the first support rod, and the two support components are detachably connected to the second support rod, and the signage includes multiple sub-signage pieces spliced ​​along the first direction, during the installation of the signage on the power tower, power personnel can fold and store the two support components relative to the first support rod, and deliver them along with the second support rod and multiple sub-signage pieces to the power tower's signage area. At the sign installation location, after the first support pole is fixed to the power tower, the positions of the two support components relative to the first support pole are adjusted so that each sign can slide to the two support components in the first direction through the connecting parts on its upper and lower sides. Then, the second support pole is fixedly connected to the two support components and the power tower respectively. At this time, the sign composed of multiple sign sub-signs will be supported and locked by the two support components in the upper and lower directions, and will be resisted by the first and second support poles in the first direction, so that the sign is in a stable state.

[0010] During the disassembly and maintenance process, after removing the second support pole, the power personnel slid multiple signboards off the two support components along the first direction, and then slid new signboards along the first direction to connect them to the two support components. Finally, the second support pole was fixed to the two support components and the power tower respectively.

[0011] This utility model adopts the above-mentioned unique structural design, which facilitates installation and disassembly by power personnel, reduces the difficulty of replacement, eliminates the need for hoisting, saves manpower and material resources, and reduces maintenance costs.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0033] In the description of this utility model, it should be understood that features specified as "first" or "second" may explicitly or implicitly include one or more of those features. In the description of this utility model, unless otherwise stated, "several" means one or more, and "multiple" means two or more.

[0034] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0035] The following is for reference. Figures 1 to 5 This invention describes the signage iron components and signage assemblies for power towers provided according to embodiments of the present invention.

[0036] like Figures 1 to 5 As shown, the signage iron component for power towers according to the first aspect of this utility model can be used in the installation of signs, especially in conjunction with signs installed on power towers. The signage iron component for power towers in this embodiment has the advantages of convenient assembly and disassembly, low replacement difficulty, and low maintenance cost.

[0037] The metal signage component of the power tower has a first direction, a second direction, and a vertical direction, wherein the first direction, the second direction, and the vertical direction are arranged perpendicularly to each other. In this embodiment, the first direction is assumed to be the left-right direction, and the second direction is assumed to be the front-back direction. The following is a detailed explanation using the structure of the metal signage component of the power tower in its assembled state as an example.

[0038] The signage iron components of the power tower include a first support rod 110, a support assembly 120, and a second support rod 130.

[0039] The length of the first support rod 110 extends vertically. It is understood that the cross-sectional shape of the first support rod 110 can be circular, square, or other shapes. The first support rod 110 can be a solid structure or a hollow structure. The specific dimensions of the first support rod 110 are not limited. In this embodiment, the first support rod 110 is a hollow square rod, which reduces the weight of the first support rod 110.

[0040] The length of the support assembly 120 extends along a first direction. The support assembly 120 is located on one side of the first support rod 110 along the first direction. Two support assemblies 120 are provided, and the two support assemblies 120 are symmetrically arranged about the first support rod 110 in the vertical direction. One support assembly 120 is located at the upper end of the first support rod 110, and the other support assembly 120 is located at the lower end of the first support rod 110. One end of the two support assemblies 120 is connected to the upper and lower ends of the first support rod 110, respectively, so that the two support assemblies 120 are mounted on the first support rod 110. Furthermore, one end of the support assembly 120 is configured to rotate relative to the first support rod 110 about a rotation axis extending along a second direction, so that the two support assemblies 120 can be folded and stored.

[0041] Understandably, in some examples, one end of each of the two support components 120 is mounted to the first support rod 110 via a hinge shaft, allowing the support components 120 to swing relative to the first support rod 110. In other examples, one end of each of the two support components 120 is fixed to the first support rod 110 by welding or bolting, while the two support components 120 themselves can rotate relative to one end. The rotation angle of the support components 120 is not limited.

[0042] Because the two support components 120 are arranged symmetrically vertically, they can rotate relative to the first support rod 110 in either the forward or reverse direction. Therefore, when one support component 120 rotates in the forward direction, the other support component 120 rotates in the reverse direction. Figure 3 As shown, the lower support assembly 120 swings clockwise downwards to its vertical position, while the upper support assembly 120 swings counterclockwise upwards to its vertical position. At this point, both support assemblies 120 swing outwards relative to the first support rod 110. By folding the two support assemblies 120, the space occupied by the support assemblies 120 in the first direction is reduced, making it easier for power personnel to lift the first support rod 110 and the two support assemblies 120 in the folded state to the location where the power tower sign is installed.

[0043] The second support rod 130 extends vertically and is located on the side of the support assembly 120 away from the first support rod 110 along the first direction; that is, the two support assemblies 120 are located between the first support rod 110 and the second support rod 130. It is understood that the cross-sectional shape of the second support rod 130 can be square, circular, or other shapes. The second support rod 130 can be designed as a hollow or solid structure. The specific dimensions of the second support rod 130 are not limited. In this embodiment, the second support rod 130 is a hollow square rod, and its dimensions are the same as those of the first support rod 110. The second support rod 130 and the first support rod 110 are arranged opposite to each other and spaced apart along the first direction.

[0044] The second support rod 130 is detachably connected to the other ends of the two support components 120, for example, by screws, so that the first support rod 110, the two support components 120, and the second support rod 130 together form a square opening for installing the sign. It is understood that when the two support components 120 are rotated to be perpendicular to the first support rod 110, the two support components 120 and the first support rod 110 together form a U-shaped opening structure. At this time, the power personnel can insert the sign into the opening structure along the first direction. After the sign is installed, the second support rod 130 is moved closer to the support component 120 along the first direction and fixedly connected to the support component 120, so that the first support rod 110, the second support rod 130, and the two support components 120 together surround the sign. The other ends of the second support rod 130 and the support components 120 can be connected by a tongue-and-groove structure for installation positioning.

[0045] Both the first support rod 110 and the second support rod 130 are provided with mounting parts, which can be used for detachable connection with the power tower. It is understood that the mounting part can be a mounting hole, through which bolts are passed and through bolt holes on the power tower to fix the first support rod 110 or the second support rod 130 to the power tower. Alternatively, the mounting part can be a connecting plate, with the first support rod 110 or the second support rod 130 integrally formed with the connecting plate. The connecting plate is provided with bolt holes, through which bolts are passed and through bolt holes on the power tower to install the first support rod 110 or the second support rod 130 onto the power tower. Multiple mounting parts are provided on the first support rod 110 and arranged at intervals in the vertical direction. Multiple mounting parts are also provided on the second support rod 130 and arranged at intervals in the vertical direction.

[0046] The sign includes multiple sign sub-signs 200, which are joined together along a first direction. Understandably, in some examples, both sides of the sign sub-sign 200 along the first direction are flat, and any two adjacent sign sub-signs 200 are in surface contact, abutting against each other. In other examples, the sign sub-signs 200 have grooves and protrusions on their two sides along the first direction, and any two adjacent sign sub-signs 200 are joined together by fitting the protrusions and grooves. In still other examples, both sides of the sign sub-sign 200 along the first direction have stepped portions extending vertically, and any two adjacent sign sub-signs 200 are joined together by interlocking the stepped portions.

[0047] Each sign 200 has a connecting portion at its upper and lower ends. The support assembly 120 is configured to be slidably and detachably connected to the connecting portion along a first direction. Understandably, in some examples, the connecting portion has connecting holes. During the movement of each sign 200 along the first direction, the support assembly 120 can pass through the connecting holes in the connecting portion, allowing the upper and lower ends of the sign 200 to connect to two support assemblies 120 respectively. This allows the sign 200 to be supported by the support assemblies 120 and limited in both the vertical and second directions. In other examples, the connecting portion may be T-shaped when viewed along the first direction. Correspondingly, the support assembly 120 has a T-shaped groove, allowing the connecting portion to slide into or out of the T-shaped groove along the first direction.

[0048] As the sign 200 approaches the first support pole 110 in the first direction, the two support components 120 can establish a snap-fit ​​relationship with the sign 200. As the sign 200 moves away from the first support pole 110 in the first direction, the sign 200 can detach from the two support components 120, making the sign 200 detachable from the support components 120. When multiple sign 200s are spliced ​​together to form a sign, the sign can clearly display warnings such as "High Voltage Danger, Warning Climbing" and "Beware of Electric Shock".

[0049] Furthermore, the first support rod 110 and the second support rod 130 are configured to abut against the corresponding signage sub-plates 200. It is understood that when multiple signage sub-plates 200 are spliced ​​together and slidably connected to the two support components 120 along the first direction, the multiple signage sub-plates 200 together form a sign, and the sign is located between the first support rod 110 and the second support rod 130, with the two sides of the sign contacting the first support rod 110 and the second support rod 130 respectively along the first direction. The signage sub-plates 200 and the first support rod 110, and the signage sub-plates and the second support rod 130, can be connected via a concave-convex structure, enabling a snap-fit ​​action between the signage sub-plates 200 and the first support rod 110, and also between the signage sub-plates 200 and the second support rod 130.

[0050] In the signage component of the power tower provided in this embodiment of the utility model, since the two support components 120 are arranged symmetrically about the first support rod 110, and the two support components 120 can rotate relative to the first support rod 110, and the two support components 120 are detachably connected to the second support rod 130, and the signage includes multiple sub-signs 200 spliced ​​along a first direction, during the work of fixing the signage on the power tower, power personnel can first fold and store the two support components 120 relative to the first support rod 110, and send them together with the second support rod 130 and multiple sub-signs 200 to the signage installation position on the power tower. At this time, the first support rod 110, the second support rod 130 and the multiple sub-signs 200 can be loaded with cloth bags or tied with ropes, thereby facilitating subsequent transportation and transfer to the signage installation position.

[0051] After the first support pole 110 is fixed to the power tower, the power personnel first adjust the positions of the two support components 120 relative to the first support pole 110, ensuring that the support components 120 are perpendicular to the first support pole 110. Then, each signboard 200 is slidably connected to the two support components 120 along the first direction through its upper and lower connecting parts. Next, the second support pole 130 is fixedly connected to the two support components 120 and the power tower, thus fixing the first support pole 110 and the second support pole 130 onto the power tower. The two support components 120 and the multiple signboards 200 are fixed to the first support pole 110 and the second support pole 130. At this time, the signboard composed of multiple signboards 200 is supported and secured by the two support components 120 in the vertical direction, and resisted by the first support pole 110 and the second support pole 130 in the first direction, ensuring that the signboard is in a stable state and can effectively resist wind force without easily deforming.

[0052] During the dismantling and maintenance of the signs, the power workers first removed the second support pole 130 from the power tower, and then slid multiple sign sub-plates 200 off the two support components 120 one by one along the first direction to complete the dismantling of the old signs. Next, multiple new sign sub-plates 200 were slid one by one along the first direction toward the first support pole 110, so that the two support components 120 could be slidably connected to the sign sub-plates 200. Finally, the second support pole 130 was fixed to the two support components 120 and the power tower respectively by bolt connection, without the need to dismantle the first support pole 110 and the two support components 120.

[0053] It is understood that the sign iron component of the power tower provided in this utility model embodiment adopts the above-mentioned reasonable and unique technical solution, which can facilitate the installation and dismantling of power personnel, reduce the difficulty of replacing the sign, and eliminate the need for hoisting, thereby saving a lot of manpower and material resources and effectively reducing maintenance costs.

[0054] In some embodiments, such as Figures 1 to 4 As shown, each support assembly 120 includes a connecting rod 123, the length of which extends along a first direction, and the connecting rod 123 is configured to be slidably connected along the first direction and detachably connected to the connecting portion.

[0055] It is understood that the connecting rod 123 can be hollow or solid. The connecting rod 123 can be a square rod or a round rod. The connecting part is provided with a connecting hole, and when the connecting part moves relative to the connecting rod 123 in the first direction, the connecting part can be sleeved on the connecting rod 123 through the connecting hole. In this embodiment, the connecting rod 123 is a hollow round rod.

[0056] Furthermore, such as Figure 4 As shown, each support assembly 120 also includes a support rod 121 and a connecting block 122. The support rod 121 extends along a first direction and is located on the side of the connecting rod 123 away from the square opening in the vertical direction. The support rod 121 and the connecting rod 123 are arranged parallel to each other, with a vertical distance between them. For the upper support assembly 120, the support rod 121 is located above the connecting rod 123; for the lower support assembly 120, the support rod 121 is located below the connecting rod 123.

[0057] Furthermore, a plurality of connecting blocks 122 are provided between the support rod 121 and the connecting rod 123. The plurality of connecting blocks 122 are arranged at certain intervals along the first direction, and the upper and lower ends of the connecting blocks 122 are fixedly connected to the support rod 121 and the connecting rod 123, respectively. The vertical spacing and the specific shape of the connecting blocks 122 are not limited. In this embodiment, the connecting blocks 122 are integrally formed with the support rod 121 and the connecting rod 123, and the number of connecting blocks 122 is four.

[0058] Furthermore, such as Figure 4 As shown, each support assembly 120 also includes a mounting base 125, a rotating block 124, and a pin. The mounting base 125 is located on the side of the support rod 121 along the first direction near the first support rod 110, and the mounting base 125 and the first support rod 110 can be fixedly connected by bolts. The specific shape of the mounting base 125 is not limited.

[0059] The upper end of the rotating block 124 is hinged to the mounting base 125 via a hinge shaft. The hinge axis of the rotating block 124 extends along the second direction. The lower end of the rotating block 124 is fixedly connected to one end of the support rod 121, enabling the rotating block 124 to drive the support rod 121, connecting block 122, and connecting rod 123 to rotate forward or backward together. Both the rotating block 124 and the mounting base 125 are provided with positioning holes 126, which extend through the second direction. Furthermore, the pin is configured to be able to be inserted into both the positioning holes 126 of the rotating block 124 and the mounting base 125 simultaneously along the second direction, thereby creating a locking effect between the rotating block 124 and the mounting base 125, so that the connecting rod 123 is perpendicular to the first support rod 110.

[0060] Understandably, the pin can be connected to the mounting base 125 or the support rod 121 via a rope to prevent it from being easily lost. When the rotating block 124 drives the support rod 121 and the connecting rod 123 to rotate from a vertical state to a horizontal state, the positioning hole 126 on the rotating block 124 and the positioning hole 126 on the mounting base 125 are opposite to and connected in the second direction. At this time, the pin can be inserted in the second direction. Through the positioning and connecting action of the pin, the rotating block 124 is fixed to the mounting base 125 and cannot rotate, thus ensuring that the support rod 121 and the connecting rod 123 both extend in the first direction and are perpendicular to the first support rod 110. This makes it convenient for power personnel to move each sign 200 in the first direction and allows the two connecting parts on the sign 200 to slide to the two connecting rods 123. After the two support assemblies 120 are fixedly connected to the second support rod 130, the pin can be removed.

[0061] The number of positioning blocks is not limited to one. Positioning hole 126 can be a square hole or a round hole.

[0062] Specifically, the pin assembly includes a positioning bolt and a connecting nut. The positioning hole 126 is a circular hole, and the positioning bolt has a cylindrical positioning portion that fits into the positioning hole 126. The positioning bolt also has a threaded portion, the outer diameter of which is smaller than the outer diameter of the positioning portion, allowing the threaded portion to pass through the positioning hole 126. Furthermore, the positioning bolt is configured to pass through both the positioning hole 126 of the rotating block 124 and the positioning hole 126 of the mounting base 125, and is threadedly connected to the connecting nut. It can be understood that the positioning portion of the positioning bolt positions and locks the rotating block 124 and the mounting base 125, causing the support rod 121 and the connecting rod 123 to extend along the first direction. The threaded portion of the positioning bolt connects to the connecting nut, ensuring the pin assembly is securely fixed between the mounting base 125 and the rotating block 124.

[0063] In some embodiments, both the first support rod 110 and the second support rod 130 are provided with slots for engaging with corresponding signage sub-plates 200. The slots extend vertically. In this embodiment, the first support rod 110 is located on the left side of the support assembly 120, and the second support rod 130 is located on the right side of the support assembly 120. The right side of the first support rod 110 is provided with a slot, and the left side of the second support rod 130 is also provided with a slot.

[0064] Understandably, the signboard, composed of multiple signboard sub-plates 200, can be inserted into corresponding slots on both sides along the first direction, with the inner wall of the slot fitting snugly against the signboard. The cross-sectional shape of the slot can be square. By providing the slots, both the first support rod 110 and the second support rod 130 can engage with the signboard, thereby enhancing the fixing effect of the signboard iron components of the power tower on the signboard. The extension length of the slot is equal to or greater than the vertical dimension of the signboard.

[0065] like Figures 1 to 5 As shown, the sign assembly according to the second aspect of the present invention can be fixedly installed on a power tower to effectively perform the warning function.

[0066] The sign assembly includes a sign and a sign iron component for a power tower as described in the first aspect embodiment. The sign includes multiple sub-signs 200, which are arranged sequentially along a first direction and spliced ​​together. Each sub-sign 200 has a connecting portion at its upper and lower ends, and the connecting portion is configured to slide along the first direction and connect to a support assembly 120, so that the connecting portion and the support assembly 120 engage with each other.

[0067] Understandably, the surface of the sub-label 200 may be coated with a rust inhibitor. This rust-preventive treatment helps prevent the sub-label 200 from easily rusting.

[0068] Specifically, such as Figure 1 and Figure 5 As shown, each sign 200 includes a sign body 210 and connectors 220. The sign body 210 can be made of metal such as stainless steel, and some warning text is printed on it. The sign body 210 is a thin, rectangular plate. The upper and lower ends of the sign body 210 are provided with several connecting portions, each including two connectors 220. The two connectors 220 are arranged opposite each other along a second direction. One end of each connector 220 is a flat block that can fit and be fixedly connected to the sign body 210, while the other end is an arc shape, forming a connecting hole for the support assembly 120 to slide into or out along a first direction. In this embodiment, the connecting hole is a round hole, which can be adapted to connect with the connecting rod 123 of the support assembly 120.

[0069] It is understandable that, since the other ends of the two connectors 220 are arc-shaped and are spaced apart along the second direction, the two connectors 220 can jointly form a clearance opening 230 that communicates with the connection hole. The clearance opening 230 can make way for the connecting block 122 between the support rod 121 and the connecting rod 123, so that the connecting part can be fitted into the connecting rod 123 along the first direction, and can also slide off the connecting rod 123 along the first direction.

[0070] In some embodiments, such as Figure 5 As shown, the card body 210 is provided with a through hole 240, which extends through in the second direction. The through hole 240 can be a round hole. Moreover, the through holes 240 of all card bodies 210 are configured to allow a rope to pass through so as to connect all card bodies 210 together.

[0071] In this embodiment, the through hole 240 can be provided at the upper or lower end of the sign body 210. During installation or disassembly, a rope is passed through the through holes 240 on all the sign bodies 210 in sequence to connect all the sign bodies 210, so that all the sign bodies 210 can be connected and are not easily lost or separated. At the same time, it is convenient for power personnel to move all the sign bodies 210.

[0072] In the sign assembly provided in this embodiment of the utility model, by using the sign in conjunction with the sign iron component of the power tower with the above-mentioned structure, the ease of disassembly and assembly can be improved, the difficulty of replacing the sign can be reduced, and maintenance costs can be reduced.
