Description

Technical Field

[0001] The utility model relates to the field of transmission and transformation line maintenance structures, and specifically to an installation and maintenance device for transmission and transformation lines. Background Technique

[0002] The transmission and transformation line uses a transformer to boost the voltage of the electric energy generated by the generator, and connects it to the transmission line through control devices such as circuit breakers. The overhead transmission line is a common form of this structure, which mainly relies on power towers to support the wires. However, since the wires connecting two adjacent power towers are usually long, they may sag or swing significantly due to gravity. To optimize the installation effect of the wires, we usually add multiple utility poles along the path of the wires to provide continuous support along the wire's direction, thereby improving the overall installation effect.

[0003] When the existing installation and maintenance device for transmission and transformation lines is used to repair the wires at the top of the utility pole, the staff needs to wear climbing equipment to climb up the pole to the top to repair and maintain the installation of the wires. As a result, it is relatively inconvenient for the staff to climb on the pole. At this time, there is a "Installation and Maintenance Device for Transmission and Transformation Lines" with the patent number "202320856542.3". This patent provides an installation and maintenance device for transmission and transformation lines, which includes a pole fixed to the ground and a mounting frame installed at the top of the pole. The pole is provided with a ladder, and the ladder includes a plurality of foot rings distributed along the length direction of the pole. The foot rings are detachably installed on the pole. The foot ring includes a foot bar and several connecting rods. The foot bar is fixed to several connecting rods at the same time. The end of the connecting rod away from the foot bar passes through the pole and is threadedly connected with a clamping nut. Although the above patent improves the convenience of the staff climbing along the pole, there are still many problems. For example, although the design of the foot ring provides a climbing fulcrum for the staff, its foot space is relatively small, which may limit the movement range of the staff's feet, increase the difficulty and discomfort during the climbing process. Especially during long-term climbing or high-altitude operations, the small foot space may cause foot fatigue or even pose a safety hazard. Moreover, the foot ring is fixed to the pole through connecting rods and clamping nuts. Although this connection method is convenient for installation and disassembly, in the long-term use or under harsh weather conditions, there may be stability problems. If the connection loosens or the nut falls off, it will pose a safety threat to the staff during the climbing process. Content of the Utility Model

[0004] Based on this, the purpose of the utility model is to provide an installation and maintenance device for transmission and transformation lines to solve the technical problems that the foot space of the foot ring in the existing installation and maintenance device for transmission and transformation lines is small and the stability is poor, which may cause inconvenience for the staff to climb and pose a safety hazard.

[0005] To achieve the above object, the utility model provides the following technical solutions: A transmission and transformation line installation and maintenance device, including a utility pole, the utility pole includes a pole body and a mounting bracket, the mounting bracket is used for installing circuit wires, and a maintenance mechanism is arranged on the outer side of the pole body. The maintenance mechanism includes a rotating shaft, connecting brackets are arranged on both sides of the rotating shaft, an arc-shaped pedal is arranged above the inner side of the connecting bracket, and the arc-shaped pedal is sleeved on the pole body;

[0006] A butt joint ring is arranged below the inner side of the connecting bracket, and the butt joint ring is used for supporting the connecting bracket after the connecting bracket rotates;

The ingenious design of the maintenance mechanism, especially components such as the rotating shaft, connecting brackets, and arc-shaped pedals, makes the maintenance and repair work more convenient and safe. The sleeved design of the arc-shaped pedal and the pole body ensures the stability of the structure and the convenience of use.

[0009] Furthermore, two groups of the maintenance mechanisms are provided, and the two groups of maintenance mechanisms are arranged mirror-symmetrically along the central axis of the pole body.

This design not only facilitates workers to perform maintenance from different angles but also improves work efficiency and safety.

[0011] Furthermore, the material of the maintenance mechanism is aluminum alloy, which facilitates workers to repair the circuit wires on the mounting bracket.

[0012] By adopting the above technical solutions, the aluminum alloy material makes the maintenance mechanism both light and strong, corrosion-resistant, and easy to maintain. The selection of this material reduces the burden on workers and ensures the service life and safety of the maintenance mechanism.

[0013] Furthermore, a lifting mechanism is arranged on the outer surface and the upper part of the back of the pole body, and the lifting mechanism includes a mounting seat.

[0014] By adopting the above technical solutions, the lifting mechanism provides a convenient means for the reset of the maintenance mechanism, reducing the difficulty and risk of manual reset. At the same time, it also serves as an auxiliary device to improve the use efficiency and safety of the overall device.

[0015] Furthermore, a winding groove is formed inside the mounting base, and a motor is arranged on one side of the mounting base.

[0016] By adopting the above technical solution, the mounting base serves as a stable foundation for the lifting mechanism. The perfect combination of the winding groove formed inside it with the motor and the winding roller realizes the mechanized reset operation, which not only greatly reduces the labor intensity of workers, but also improves the accuracy and efficiency of the reset operation.

[0017] Furthermore, the output end of the motor penetrates through the mounting base and extends into the winding groove, and a winding roller is arranged at the output end of the motor.

[0018] By adopting the above technical solution, the output end of the motor directly penetrates through the mounting base and is connected to the winding roller, making the overall structure more compact and reducing unnecessary space occupation.

[0019] Furthermore, a traction rope is wound around the winding roller, and the traction rope penetrates through a plurality of arc-shaped pedals.

In particular, the arc-shaped pedal not only provides a spacious foot space but also conforms to the ergonomic design, effectively reducing foot fatigue during long-term climbing operations. At the same time, the arc-shaped design enables it to better adapt to the circular cross-section of the electric pole, thereby increasing the stability and comfort of the pedal. In addition, the abutting ring provides a stable support after the connecting frame rotates, ensuring that the maintenance mechanism can remain stable in the unfolded state, which provides a reliable maintenance environment for the staff. The design of the connecting rod is also quite ingenious. It enables multiple connecting frames to rotate synchronously, which not only facilitates the staff to quickly unfold or retract the maintenance mechanism but also greatly improves the operation efficiency and reduces the cumbersome steps in adjusting the maintenance mechanism. These innovative designs jointly solve the problems of small space and poor stability of the traditional footrest ring, significantly reducing the safety hazards during long-term climbing operations and simplifying the operation steps, thus improving the overall work efficiency;

[0025] 2. The utility model solves the problems of small space and poor stability of the traditional footrest ring by setting a lifting mechanism. Through the lifting mechanism, the maintenance mechanism can be quickly reset, which greatly improves the work efficiency and reduces the physical burden of the staff. The mounting seat, as a stable foundation of the lifting mechanism, not only provides a solid support but also is ingeniously designed with a winding groove to facilitate the neat storage of the winding roller and the traction rope, ensuring the compactness of the entire mechanism and the smoothness of the work. The motor injects power into the lifting mechanism. It drives the winding roller to rotate flexibly, thereby precisely controlling the winding and unwinding of the traction rope. The winding roller plays a core role in this process. Its rapid winding and releasing of the traction rope are the key to realizing the quick reset of the maintenance mechanism. The traction rope not only plays a role in connection and transmission but also provides an additional attachment point for the staff, which enhances the safety and stability during climbing. Generally speaking, the ingenious design of the lifting mechanism and its various components not only realizes the automatic reset function but also improves the work efficiency and operation safety in many aspects.

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation to the present invention.

[0032] Next, the embodiments of the present invention will be described according to the overall structure of the present invention. Embodiment

[0033] A power transmission and transformation line installation and maintenance device, as Figures 1 - 4 shown, includes an electric pole 1. The electric pole 1 includes a pole body 101 and a mounting bracket 102. The mounting bracket 102 is used for installing circuit lines. A maintenance mechanism 2 is arranged on the outer side of the pole body 101. The maintenance mechanism 2 includes a rotating shaft 201. Connecting frames 202 are arranged on both sides of the rotating shaft 201. An arc-shaped pedal 203 is arranged above the inner side of the connecting frame 202. The arc-shaped pedal 203 is sleeved on the pole body 101; a contact ring 204 is arranged below the inner side of the connecting frame 202. The contact ring 204 is used to support the connecting frame 202 after the connecting frame 202 rotates; there are multiple connecting frames 202, and the multiple connecting frames 202 are arranged at equal intervals from top to bottom. Connecting rods 205 are arranged on both sides of the multiple connecting frames 202. The connecting rods 205 are used to rotate the multiple connecting frames 202 synchronously. The electric pole 1 serves as a basic support structure, stably supporting the mounting bracket 102 and the circuit lines. The design of the mounting bracket 102 facilitates the quick installation and fixation of the circuit lines. The maintenance mechanism 2 provides a convenient and safe operation platform for maintenance and repair work through the ingenious combination of components such as the rotating shaft 201, the connecting frame 202, and the arc-shaped pedal 203. In particular, the sleeved design of the arc-shaped pedal 203 on the pole body 101 ensures the stability of the structure and the convenience of use, enabling maintenance personnel to easily climb and operate.

[0034] Refer to Figure 1 , Figure 2 , Figure 3 , two groups of maintenance mechanisms 2 are arranged. The two groups of maintenance mechanisms 2 are arranged mirror-symmetrically along the central axis of the pole body 101. By arranging two groups of maintenance mechanisms 2 and configuring them mirror-symmetrically along the central axis of the pole body 101, more operation space and flexibility are provided for maintenance personnel. This layout not only facilitates maintenance personnel to operate from different angles, but also can effectively share the workload, improve work efficiency, and ensure the safety of operation.

[0035] Refer to Figure 1 、 Figure 2 、 Figure 3 , the material of the maintenance mechanism 2 is aluminum alloy. With the aluminum alloy material for the maintenance mechanism 2, it is convenient for workers to maintain the circuit wires on the mounting rack 102. Using aluminum alloy as the material of the maintenance mechanism 2 not only ensures the lightness of the structure but also has good strength and corrosion resistance. The light weight characteristic of aluminum alloy reduces the burden on maintenance personnel, making climbing and operation easier. At the same time, the corrosion resistance of aluminum alloy extends the service life of the maintenance mechanism and reduces the maintenance cost. Embodiment

[0036] Refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 , a lifting mechanism 3 is provided on the outer surface and the upper part of the back of the rod body 101. The introduction of the lifting mechanism 3 provides mechanical assistance for the reset of the maintenance mechanism 2, greatly reducing the difficulty and risk of manual reset. In addition, the lifting mechanism can also provide an additional support point for maintenance personnel when necessary, increasing the safety and convenience of the overall operation.

[0037] Refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 , a winding groove is formed inside the mounting seat 301. A motor 302 is provided on one side of the mounting seat 301. The output end of the motor 302 penetrates through the mounting seat 301 and extends into the winding groove, and a winding roller 303 is provided at the output end of the motor 302. As the stable base of the lifting mechanism 3, the winding groove designed inside the mounting seat 301 is perfectly combined with the motor 302 and the winding roller 303, realizing the rapid reset of the maintenance mechanism 2. The motor 302 drives the winding roller 303 to automatically wind the traction rope 304, simplifying the reset operation process, improving the work efficiency, and reducing the labor intensity of maintenance personnel.

[0038] Refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 , a traction rope 304 is wound around the winding roller 303, and the traction rope 304 penetrates through a plurality of arc-shaped pedals 203. Through the penetrating connection between the traction rope 304 and the plurality of arc-shaped pedals 203, the stability and synchronization of the lifting mechanism 3 when resetting the maintenance mechanism 2 are ensured. While simplifying the reset operation, this connection method also enhances the safety and reliability of the overall device.

[0039] Refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4, the lifting mechanism 3 is used to reset the maintenance mechanism 2, and the traction rope 304 can provide an additional climbing point. The lifting mechanism 3 is not only used to assist in the reset operation of the maintenance mechanism 2, but its traction rope 304 can also provide an additional climbing point for maintenance personnel when necessary. This design fully considers the safety needs of maintenance personnel during high-altitude operations, improves the humanization and practicability of the device, and provides double safety guarantees for maintenance work.

[0040] The implementation principle of the present utility model is as follows: First, ensure that all mechanisms and components have been correctly installed on the utility pole 1, and check their stability and functionality. In the unused state, the connecting frame 202 is vertically upward, the arc-shaped pedal 203 is sleeved with the pole body 101, and the entire maintenance mechanism 2 is closely attached to the pole body 101 without occupying additional space;

[0041] When line maintenance is required, the maintenance personnel operate the connecting rod 205. Through its linkage mechanism, multiple connecting frames 202 are rotated synchronously. Then, as the connecting frame 202 rotates, the arc-shaped pedal 203 gradually moves away from the pole body 101, forming upward steps one by one. When the connecting frame 202 rotates to an appropriate position, the abutting ring 204 abuts against the pole body 101, providing a stable standing platform for the maintenance personnel;

[0042] The maintenance personnel can climb upward along the unfolded arc-shaped pedal 203 to reach the position of the line to be maintained. On each arc-shaped pedal 203, the maintenance personnel can perform work such as installing, maintaining, or repairing the circuit line. After the maintenance work is completed, the maintenance personnel need to reset the maintenance mechanism 2 for future use or to ensure safety;

[0043] After that, by controlling the motor 302 to start, driving the winding roller 303 to rotate, and winding the traction rope 304. Then, since the traction rope 304 is connected to the arc-shaped pedal 203, the winding action can help lift and stabilize the arc-shaped pedal 203 to ensure its complete reset.

[0044] Parts not involved in the present utility model are the same as or can be implemented using existing technologies, and will not be elaborated here.

[0045] Although the embodiments of the present utility model have been shown and described, the specific embodiments are only explanations of the present utility model and are not limitations thereof. The specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art can make modifications, substitutions, and variations that do not contribute creatively to the embodiments according to needs, but as long as they are within the scope of the claims of the present utility model, they are protected by the patent law.
