Description

Technical Field

[0001] This utility model relates to the field of power operation and maintenance technology, specifically to a composite cement tower fixing point device. Background Technology

[0002] Concrete power transmission towers are used in industries such as power, telecommunications, and railways. They are constructed of reinforced concrete and serve as the main supporting structure for overhead transmission lines. To reduce lightning strike failures on transmission lines, lightning protection measures are implemented, such as reducing the grounding resistance of the towers, improving the insulation level of the lines, using negative angle protection, and installing coupling ground wires.

[0003] Currently, surge arresters are widely used for lightning protection of transmission lines. During installation, surge arresters are fixed to the towers using U-ring bolts. However, in actual use, it has been found that because the U-ring bolts are exposed to the environment for a long time, they are susceptible to erosion from rainwater, salt spray, and temperature differences. This causes the plating on the bolt surface to peel off, leading to bolt damage and detachment. Consequently, the lightning protection wire loses its effective fixation and is prone to unintended entanglement with exposed conductors.

[0004] However, when the tower is high, the initial position of the lightning protection wire after it is fixed will be high. After the lightning protection wire falls off, the workers still need to climb to a height close to the original installation height to reset it. Moreover, the workers on the tower will be constrained by factors such as height and ergonomics, making it more difficult to maintain the fallen end of the lightning protection wire. Utility Model Content

[0005] In view of this, the present invention provides a composite cement tower fixing point device to solve the problem of the difficulty in maintaining the detached end of the lightning protection wire when the tower is high.

[0006] Specifically, the composite cement tower fixing point device provided by this utility model includes a vertical arm, a horizontal arm, a lifting component, and a guide component. The vertical arm is installed on the cement tower, with its length direction parallel to the axial direction of the cement tower. The horizontal arm's length direction is parallel to the radial direction of the cement tower, and one end of the horizontal arm along its length direction is fixedly connected to the side of the vertical arm facing away from the ground. The lifting component has a connecting end and a handheld end facing away from each other. The connecting end is used to connect to the detached end of the lightning protection wire, and the handheld end is for maintenance personnel to hold. The guide component is installed on the horizontal arm and has a guiding surface. The entrance end of the guiding surface faces the cement tower, and after being raised by the vertical arm, the entrance end of the guiding surface is positioned along the height direction above the original installation height of the detached end of the lightning protection wire. The exit end of the guiding surface faces the ground, guiding the handheld end of the lifting component to the ground.

[0007] Beneficial effects: By installing the vertical arm, the entrance end of the guide surface can be positioned above the original installation height of the detached lightning conductor. Ground-based maintenance personnel can directly operate the handheld end of the lifting device to guide the detached conductor to gradually rise until it reaches the original installation height. Once this is achieved, maintenance personnel on the tower can align and lock the detached conductor. Compared to traditional maintenance processes where personnel need to climb to the original height of the lightning conductor, the vertical arm reduces the working height of maintenance personnel, thus lowering the difficulty of high-altitude operations.

[0008] In one optional embodiment, the composite cement tower fixing point device further includes a reinforcing member, the length direction of which is intersected with the radial direction of the cement tower. One end of the reinforcing member along its length direction is fixedly connected to the vertical arm via a connector, and the other end of the reinforcing member along its length direction is connected to the side of the crossarm opposite to the vertical arm via a connector.

[0009] In one alternative implementation, along the height direction, the connection between the reinforcement and the vertical support is located below the connection between the crossarm and the vertical support.

[0010] In one alternative implementation, along the height direction, the connection between the reinforcement and the vertical support is located above the connection between the crossarm and the vertical support.

[0011] In one optional embodiment, the composite cement tower fixing point device further includes a clamp, which is sleeved on the cement tower; wherein the vertical support is installed on the cement tower through the clamp.

[0012] In one optional embodiment, the clamp includes a first clamp body and a second clamp body, each of which is an arc-shaped structure. The first clamp body and the second clamp body are connected to form a circular receiving chamber for accommodating the cement tower.

[0013] In one optional embodiment, the first clamp body is provided with a first mounting ear plate at the end near the second clamp body, and the second clamp body is provided with a second mounting ear plate at the end near the first clamp body. The first mounting ear plate is connected to the second mounting ear plate through a connector.

[0014] In one optional embodiment, at least one of the first clamp body and the second clamp body has an elastic friction element on its inner wall. When the clamp is fitted onto the cement tower, the elastic friction element is used to abut against the outer wall of the cement tower.

[0015] In one alternative embodiment, the composite cement tower fixing point device further includes a housing, which is installed on the crossarm, the housing is used to accommodate the guide member, and the housing has an inlet and an outlet for the lifting member to pass through.

[0016] In one optional embodiment, the composite cement tower fixing point device further includes a hanging ring and a hook. The hanging ring is installed on the crossarm; the hook is used to suspend the hanging ring and is installed on the housing. Attached Figure Description

[0038] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0039] The following is combined Figures 1 to 5 The following describes embodiments of the present invention.

[0040] Specifically, such as Figure 1 As shown, the composite cement tower fixing point device includes a vertical support 1, a horizontal support 2, a lifting component 3, and a guide component 4.

[0041] Among them, the vertical support 1 is installed on the cement tower a, and the length direction of the vertical support 1 is parallel to the axis direction of the cement tower a.

[0042] The crossarm 2 is arranged parallel to the radial direction of the cement tower a along its length, and one end of the crossarm 2 along its length is fixedly connected to the side of the vertical arm 1 away from the ground.

[0043] The lifting component 3 has a connecting end 301 and a handheld end 302 arranged opposite to each other. The connecting end 301 is used to connect to the detached end of the lightning protection wire, and the handheld end 302 is for maintenance personnel to hold.

[0044] The guide 4 is installed on the crossarm 2. The guide 4 has a guide surface. The entrance end of the guide surface faces the cement tower a. The entrance end of the guide surface is raised by the vertical arm 1 and is set above the original installation height of the detached end of the lightning protection wire along the height direction. The exit end of the guide surface faces the ground and is used to guide the handheld end 302 of the lifting member 3 to the ground.

[0045] With this configuration, the entrance end of the guide surface, via the vertical arm 1, is positioned above the original installation height of the detached lightning conductor. Ground-based maintenance personnel can directly operate the handheld end 302 of the lifting component 3 to guide the detached conductor to gradually rise until it reaches the original installation height. Once this is achieved, maintenance personnel on the tower can align and lock the detached conductor. Compared to traditional maintenance methods that require personnel to climb to the original height of the lightning conductor, the vertical arm 1 configuration appropriately reduces the working height of maintenance personnel, thereby lowering the difficulty of high-altitude operations.

[0046] It should be noted that when the detached end of the lightning protection wire is returned to its original position, if... Figures 1 to 4 As shown, the bottom of the detached end is fixed to the cement tower a using the pull ring 12.

[0047] It can be noted that the lifting component 3 is preferably a rope, cable, or chain component.

[0048] It should be noted that there are no specific limitations on the construction of the guide component 4. It is sufficient that it has a boot path.

[0049] Preferably, such as Figure 1 As shown, guide 4 is selected as a pulley structure, and the guide surface is an arc-shaped guide surface.

[0050] When in use, maintenance personnel on the ground can simply drag and pull the handheld end unit 302.

[0051] In one embodiment, such as Figure 1 , Figure 3 and Figure 4 As shown, the composite cement tower fixing point device also includes a reinforcement member 5. The length direction of the reinforcement member 5 is intersected with the radial direction of the cement tower a. One end of the reinforcement member 5 along its length direction is fixedly connected to the vertical support 1 through a connector 7. The other end of the reinforcement member 5 along its length direction is connected to the side of the crossarm 2 away from the vertical support 1 through a connector 7.

[0052] With this configuration, the crossarm 2 and the vertical arm 1 are connected by the reinforcement 5, and the length direction of the reinforcement 5 is intersected with the radial direction of the cement tower a. Since the length direction of the vertical arm 1 is parallel to the axial direction of the cement tower a, and the length direction of the crossarm 2 is parallel to the radial direction of the cement tower a, a triangular support structure can be formed. This allows the crossarm 2 to transfer the vertical load it bears to the vertical arm 1 through the reinforcement 5 when suspending equipment of a certain weight. This can disperse the bending stress of the crossarm 2 itself, significantly reduce the stress at the connection between the vertical arm 1 and the crossarm 2, avoid local overload causing damage to the crossarm 2, and improve the bending resistance of the crossarm 2.

[0053] It can be noted that there is no specific limitation on the way the connection between the reinforcement 5 and the vertical support 1 is set relative to the connection between the cross support 2 and the vertical support 1. It can be set below or above it.

[0054] In one embodiment, such as Figure 1 , Figure 3 and Figure 4 As shown, along the height direction, the connection between the reinforcement 5 and the vertical support 1 is located below the connection between the cross support 2 and the vertical support 1.

[0055] This configuration, by placing the connection between the reinforcement 5 and the vertical support 1 below the connection between the crossarm 2 and the vertical support 1, allows the reinforcement 5 to provide oblique support to the end of the crossarm 2 that is away from the vertical support 1 along its length. This counteracts the downward bending tendency of the end of the crossarm 2 that is away from the vertical support 1 due to its own weight or external load, allowing the load on the crossarm 2 to be partially transferred to the lower area of ​​the vertical support 1, rather than being concentrated at the connection between the crossarm 2 and the vertical support 1. This reduces the risk of stress concentration in that area and makes the connection between the crossarm 2 and the vertical support 1 more stable after connection.

[0056] Of course, in other alternative embodiments, along the height direction, the connection between the reinforcement 5 and the vertical support 1 is located above the connection between the cross support 2 and the vertical support 1.

[0057] This configuration, by placing the connection between the reinforcement 5 and the vertical support 1 above the connection between the cross support 2 and the vertical support 1, allows the reinforcement 5 to diagonally lift the end of the cross support 2 away from the vertical support 1 along its length. This counteracts the downward bending force generated by the cross support 2's own weight or external load on the end away from the vertical support 1, allowing the load on the cross support 2 to be partially transferred to the upper area of ​​the vertical support 1, rather than concentrated at the connection between the cross support 2 and the vertical support 1. This reduces the risk of stress concentration in that area, making the connection between the cross support 2 and the vertical support 1 more stable after connection.

[0058] In one embodiment, such as Figures 1 to 5As shown, the composite cement tower fixing point device also includes a clamp 6, which is sleeved on the cement tower a; wherein, the vertical support 1 is installed on the cement tower a through the clamp 6.

[0059] This configuration, with the clamp 6 forming a ring-shaped contact surface, enables multi-point support. Compared to the single-point fixing method caused by directly connecting the vertical support 1 and the cement tower a with bolts in the conventional scheme, it can avoid excessive stress concentration in local areas, thereby reducing the risk of damage at the connection.

[0060] In one embodiment, such as Figure 1 and Figure 5 As shown, the clamp 6 includes a first clamp body 601 and a second clamp body 602. Each clamp body is an arc-shaped structure. The first clamp body 601 and the second clamp body 602 are connected to form a circular receiving chamber for accommodating the cement tower a.

[0061] This design, by making the clamp 6 a split structure and setting both the first clamp body 601 and the second clamp body 602 as arc-shaped structures, makes it easier and more tightly fitted to the outer surface of the concrete tower a. Furthermore, during installation, only the two clamp bodies need to be fitted onto the outer wall of the concrete tower a, eliminating the need to slide them in from one end of the tower, thus optimizing the on-site installation process for the clamp 6.

[0062] In one embodiment, it is still as follows Figure 1 and Figure 5 As shown, the first clamp body 601 is provided with a first mounting ear plate 603 at the end near the second clamp body 602, and the second clamp body 602 is provided with a second mounting ear plate 604 at the end near the first clamp body 601. The first mounting ear plate 603 is connected to the second mounting ear plate 604 through a connector 7.

[0063] With this configuration, a first mounting ear plate 603 is provided on the first clamp body 601, and a second mounting ear plate 604 is provided on the second clamp body 602. During installation, the two mounting ear plates are fixed using the connector 7. Furthermore, the contact between the two mounting ear plates is a surface contact, which can reduce single-point stress, avoid stress concentration, and improve the durability of the clamp 6.

[0064] In one embodiment, in the first clamp body 601 and the second clamp body 602, at least one clamp body has an elastic friction element 605 on its inner wall. When the clamp 6 is fitted onto the cement tower a, the elastic friction element 605 is used to abut against the outer wall of the cement tower a.

[0065] With this configuration, by providing an elastic friction element 605 on the inner wall of at least one of the clamp bodies 601 and 602, after installation, the elastic friction element 605 elastically abuts against the outer wall of the cement tower a, increasing the coefficient of friction between the clamp 6 and the cement tower a, so that the clamp 6 can be more firmly fixed to the outer wall of the cement tower a, preventing connection failure due to fretting wear, and reducing the risk of the crossarm 2, vertical arm 1 and reinforcement 5 sliding or falling.

[0066] Preferably, such as Figure 5 As shown, the inner walls of the first clamp body 601 and the second clamp body 602 are both provided with elastic friction elements 605.

[0067] In one embodiment, such as Figure 1 As shown, the composite cement tower fixing point device also includes a housing 8, which is installed on the crossarm 2. The housing 8 is used to accommodate the guide 4, and the housing 8 has an inlet and an outlet for the lifting member 3 to pass through.

[0068] With this configuration, by setting up the housing 8 and placing the guide 4 inside the housing 8, a physical barrier can be provided for the guide 4 to prevent damage to the guide 4 caused by tower vibration or external impact such as wind or accidental collision, and to ensure that maintenance personnel can stably apply force to the handheld end 302 of the lifting component 3.

[0069] It can be noted that the housing 8 is made of insulating materials such as engineering plastics or epoxy resin to further isolate live parts, prevent maintenance personnel from directly contacting live areas during operation, and reduce the risk of electric shock.

[0070] In one embodiment, such as Figure 1 As shown, the composite cement tower fixing point device also includes a hanging ring 9 and a hook 10. The hanging ring 9 is installed on the crossarm 2; the hook 10 is used to suspend the hanging ring 9 and is installed on the housing 8.

[0071] With this configuration, by connecting the hook 10 to the housing 8 and installing the hanging ring 9 on the crossbeam 2, when installing the housing 8, simply hook the hook 10 onto the hanging ring 9; when disassembling the housing 8, simply remove the hook 10 from the hanging ring 9. This makes it easy to disassemble and assemble the housing 8.

[0072] Furthermore, the housing 8 and the guide 4 form a seated pulley structure.

[0073] It can be noted that the hook 10 is preferably an anti-detachment structure.

[0074] At this time, a baffle 11 is provided at the opening of the hook of the hook 10. The baffle 11 is installed at the opening by a spring and a torsion spring.

[0075] When in use, an external force is applied to the baffle 11 to open the opening at the hook. During this process, the baffle 11 acts on the spring and torsion spring to store energy. Then, the hook is hooked onto the hanging ring 9. After the external force is removed, the spring and torsion spring release energy, causing the baffle 11 to gradually close the opening at the hook until it is completely closed.

[0076] This setup allows for one-way connection, preventing the hook 10 from accidentally falling off and ensuring that the hook 10 maintains a stable connection even in severe weather conditions such as strong winds.

[0077] Furthermore, an insulating coating is applied to the hanging ring 9 and hook 10 to reduce the risk of electric shock.

[0078] It can be noted that the crossarm 2 is provided with mounting holes 101, and the hanging ring 9 is installed in the mounting holes 101.

[0079] To improve the service life of the hanging ring 9, the hanging ring 9 is indirectly fixed to the crossarm 2.

[0080] Specifically, such as Figure 1 As shown, the composite cement tower fixing point device also includes a connecting rod 13, which passes through the mounting hole 101; the hanging ring 9 is an open ring component, and the opening of the hanging ring 9 is used to install the connecting rod 13. The hanging ring 9 is fixed to the crossarm 2 through the connecting rod 13.

[0081] This design, with its open opening, allows for quick installation of the hanging ring 9 onto the connecting rod 13. Simultaneously, the connecting rod 13, acting as an intermediate support, directly transfers the load on the hanging ring 9 to the mounting hole 101 on the crossarm 2, preventing the hanging ring 9 from directly contacting the mounting hole 101 and causing deformation or wear. Furthermore, it allows for flexible adjustment of the installation angle without any jamming, effectively serving as a connection and transition mechanism.

[0082] Preferably, the hanging ring 9 is a U-shaped hanging ring.

[0083] Similarly, after molding, the pulley structure can be flexibly selected in various combinations to suit different usage needs, such as single and double hook pulleys, fixed pulleys, etc.

[0084] Furthermore, the crossarm 2 has multiple mounting holes 101, which are spaced apart along the length of the crossarm 2.

[0085] Preferably, the crossarm 2 has three mounting holes 101. The three mounting holes 101 are respectively used to connect to the reinforcing member 5, to the vertical arm 1, and to the hanging ring 9.

[0086] Furthermore, the crossarm 2 has at least two mounting holes 101 for connecting with the hanging ring 9.

[0087] This configuration allows the hanging ring 9 and connecting rod 13 to be installed at different positions on the crossarm 2, thereby adapting to the suspension requirements of different positions and matching the distribution location of the detached ends of the lightning protection wire or the working range of maintenance personnel.

[0088] Similarly, the vertical support 1 is provided with multiple sets of mounting holes 101. Each set of mounting holes 101 has at least one.

[0089] Preferably, the vertical support 1 is provided with two sets of mounting holes 101, one set of mounting holes 101 is used to connect with the crossarm 2, and the other set of mounting holes 101 is used to connect with the reinforcement 5.

[0090] It can be noted that the aforementioned connector 7 is preferably a high-strength bolt or nut.

[0091] The following diagram illustrates the connection method between the vertical support 1 and the reinforcement 5.

[0092] Specifically, during installation, the mounting hole 101 in the reinforcing member 5 for connecting with the vertical support 1 is made coaxial with the mounting hole 101 in the vertical support 1 for connecting with the reinforcing member 5, and then bolts are inserted and nuts are tightened.

[0093] The aforementioned composite cement tower fixing point device is designed for detachable installation, allowing for quick replacement of components based on actual conditions, and enabling flexible disassembly and convenient assembly.

[0094] For example, the vertical support 1, horizontal support 2, and reinforcement 5 are assembled on site. The connecting rod 13 and the hanging ring 9 are installed at the mounting hole 101 on the horizontal support 2. The guide 4 is then placed into the housing 8 and connected to the top of the housing 8 using the hook 10. The hook 10 is then hooked onto the hanging ring 9. This completes the basic assembly of the composite cement tower fixing point device.

[0095] Subsequently, maintenance personnel climbed the cement tower a and gradually approached the original position of the detached end of the lightning protection wire. When they had the ability to fix the detached end of the lightning protection wire, they connected the vertical support 1 of the composite cement tower fixing point device to the cement tower a.

[0096] During the climb, if a detached end is encountered, the unintended entanglement is released, and the detached end is connected to the connecting end 301.

[0097] After the vertical support 1 in the composite cement tower fixing point device is connected to the cement tower a, the maintenance personnel standing on the ground pull and tug the end 302 of the hand until the detached end is reset, and then use the pull ring 12 to fix the detached end.

[0098] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
