Description

Technical Field

[0001] This utility model relates to the field of power equipment technology, specifically to an adjustable insulating support for power equipment. Background Technology

[0002] In the power transmission and distribution network, the power pole serves as the core support for the conductors. Insulating supports are necessary to achieve electrical isolation between the conductors and the pole, while simultaneously ensuring the stability and safety of the conductor installation. Currently, commonly used insulating supports in power equipment consist of a fixed insulating frame, limiting components, and insulators. Their core function is to fix the pole to the insulating frame via limiting components, and then use the insulating frame to support the insulators, thereby achieving insulating support for the conductors. However, existing insulating supports have many technical shortcomings in practical applications, making it difficult to meet the complex and ever-changing on-site installation requirements and long-term operation and maintenance stability requirements. The specific problems are as follows: The existing insulating bracket has a fixed relative position between the insulating frame and the limiting component, which cannot be adjusted according to the tapered requirements of the cement pole, which is thinner at the top and thicker at the bottom. The fixed structure of the bracket is difficult to adjust the installation position, and parts can only be replaced. The compatibility of the installation parts is poor. Utility Model Content

[0003] In order to solve the technical problems existing in the prior art, this application provides an adjustable insulating bracket for power equipment.

[0004] To achieve the above objectives, the technical solution adopted in this application is as follows: an adjustable insulating support for power equipment, comprising: an insulating frame, the insulating frame including a first limiting member connected to a utility pole and an insulating rod, the insulating rod being disposed on the first limiting member, and a plurality of ceramic insulators being spaced apart on the insulating rod; a stabilizing frame, the stabilizing frame including a second limiting member connected to the utility pole and a stabilizing rod, the two ends of the stabilizing rod being connected to the insulating frame and the second limiting member respectively; wherein, the insulating rod includes a mounting part and a supporting part, the ceramic insulators are located on the mounting part, the supporting part has an adjusting strip hole, and the stabilizing rod is connected to the insulating frame by screws, the screws sequentially passing through the adjusting strip hole and the stabilizing rod.

[0005] In some embodiments of this utility model, a fixing rod is provided between the stabilizer rod and the insulating frame. One end of the fixing rod is connected to the first limiting member. The stabilizer rod is provided with a plurality of fixing holes. The other end of the fixing rod is connected to any fixing hole by a bolt.

[0006] In some embodiments of this utility model, the first limiting member includes a pull rod, which is a U-shaped structure. The arc-shaped part of the U-shaped structure abuts against the outer wall of the utility pole, and the U-shaped structure extends into a pre-drilled through hole on the insulation frame. Both ends of the outer wall of the U-shaped structure are provided with external threads.

[0007] In some embodiments of this utility model, the first limiting member further includes a top block disposed on the insulating bracket. The side of the top block away from the insulating bracket has an arc-shaped groove, which can abut against the outer wall of the utility pole, and a circular locking space is formed between the top block and the pull rod.

[0008] In some embodiments of this utility model, the second limiting member includes two locking plates, the ends of the two locking plates are connected by bolts, and a receiving space for accommodating the utility pole is formed between the two locking plates. A mounting post is provided on the outer side wall of any locking plate, and the end of the stabilizing rod away from the insulating frame is connected to the mounting post.

[0009] In some embodiments of this utility model, an anti-slip layer is provided on the side of any of the locking plates that contacts the utility pole.

[0010] In some embodiments of this utility model, a washer is provided between the ceramic insulator and the insulating frame.

[0011] Beneficial effects: 1. Existing insulating supports, due to the fixed relative positions of the insulating frame and the limiting components, cannot flexibly adjust their installation position when faced with the tapered characteristics of cement poles (thinner at the top and thicker at the bottom). Adaptation can only be achieved by replacing parts, increasing costs and extending the construction period. The insulating frame includes a first limiting component that connects to the utility pole, and the stabilizing frame includes a second limiting component that connects to the utility pole. The stabilizing rod connects to both ends of the insulating frame and the second limiting component, respectively. The insulating frame has an adjustment slot, and the stabilizing rod is connected to the insulating frame via screws passing through the adjustment slot and the stabilizing rod. When installed at different heights on the cement pole, and due to differences in diameter caused by the tapered shape, the connection position of the stabilizing rod on the insulating frame can be adjusted by loosening the screws and moving it along the adjustment slot, thereby adjusting the relative distance between the first and second limiting components on the cement pole. Without replacing any parts, the first and second limiting components can be adapted to the diameter of the corresponding height cement pole, ensuring that both can fit tightly against the pole body. This effectively solves the problems of fixed structure brackets being unable to adapt to the taper of cement poles and the difficulty in adjusting the installation position, and significantly improves the installation adaptability of the bracket on cement poles of different specifications.

[0021] Please refer to Figures 1-3 This embodiment provides an adjustable insulating support for power equipment, comprising: an insulating frame, which includes a first limiting member connected to a utility pole and an insulating rod 1, wherein the insulating rod 1 is disposed on the first limiting member and a plurality of ceramic insulators 2 are spaced apart on the insulating rod 1; and a stabilizing frame, which includes a second limiting member connected to the utility pole and a stabilizing rod 3, wherein the two ends of the stabilizing rod 3 are respectively connected to the insulating frame and the second limiting member; wherein the insulating rod 1 includes a mounting part 101 and a supporting part 102, the ceramic insulators 2 are located on the mounting part 101, the supporting part 102 has an adjusting strip hole 4, and the stabilizing rod 3 is connected to the insulating frame by screws, wherein the screws pass through the adjusting strip hole 4 and the stabilizing rod 3 in sequence.

[0022] In this embodiment, the aforementioned first limiting member is used to connect the insulating frame to the utility pole, addressing the problem of poor stability of existing supports with a single fixed point. The insulating frame is elongated and is used to install the ceramic insulator 2. It connects to the first limiting member and has six pre-drilled fixing holes for installing the ceramic insulator 2, spaced apart along the length of the insulating frame. One side of the insulating frame has an adjustable slot 4 for connecting the stabilizing rod 3, which is connected to the stabilizing rod 3 via screws for an adjustable connection. In terms of load-bearing capacity, the insulating frame must bear the weight of the ceramic insulator 2 and the conductor, transferring the load to the first limiting member, which then distributes it to the utility pole.

[0023] In this embodiment, the ceramic insulator 2 is made of high-alumina ceramic material, with a columnar main body. The top has a wire fixing groove, and the bottom has a connecting component that matches the fixing holes 6 on the insulating frame. During installation, the bottom of the insulator is fixed to the pre-drilled holes on the insulating frame with bolts. Then, the wire is inserted into the fixing groove at the top of the insulator, achieving physical and electrical insulation between the wire and the insulating frame through the insulator. Simultaneously, the disc-shaped umbrella skirt structure of the ceramic insulator 2 increases the surface creepage distance, preventing rainwater and dust from forming conductive paths and preventing creepage accidents.

[0024] In this embodiment, the second limiting member has a similar structure to the first limiting member, but its size can be adjusted according to the installation position. Its diameter is slightly larger than that of the first limiting member to accommodate different heights of cement poles. It also has an anti-slip pad on its inner side and is secured to the utility pole with bolts. The second limiting member has a connection interface on its side that matches the stabilizing rod 3. One end of the stabilizing rod 3 is connected to the second limiting member via bolts or hinges, forming an auxiliary support link between the utility pole, the second limiting member, and the stabilizing rod 3. Together with the first limiting member and the insulating frame, they form a triangular support structure.

[0025] One end of the aforementioned stabilizer bar 3 is connected to the adjustment slot 4 of the insulating frame via a screw, and the other end is fixed to the connection interface of the second limiting member via a bolt. During the stress process, the stabilizer bar 3 needs to withstand the lateral tensile or compressive force generated by the external force on the insulating frame. The lateral load is transferred to the utility pole through the link of the insulating frame, the stabilizer bar 3, and the second limiting member, thus balancing the stress state of the insulating frame. At the same time, by adjusting the position of the stabilizer bar 3 within the adjustment slot 4, its angle with the insulating frame and the second limiting member can be changed, optimizing the direction of the force.

[0026] The aforementioned adjustment slot 4 is located on the side of the insulating frame and extends along the length of the insulating frame. When the bracket needs to be adjusted, the nut is loosened, and the screw can slide along the length of the adjustment slot 4, causing one end of the stabilizer 3 to move synchronously, thereby changing the connection position between the stabilizer 3 and the insulating frame, and finally adjusting the relative distance between the first limiter and the second limiter on the utility pole. After adjusting to the target position, the nut is tightened again, and the screw fits tightly with the adjustment slot 4 and the stabilizer 3, fixing the current position.

[0027] Please refer to Figure 1 and Figure 2 In some embodiments of this example, a fixing rod 5 is provided between the stabilizer 3 and the insulating frame. One end of the fixing rod 5 is connected to the first limiting member. The stabilizer 3 is provided with a plurality of fixing holes 6. The other end of the fixing rod 5 is connected to any fixing hole 6 by a bolt.

[0028] In this embodiment, the fixing rod 5 is used to lift the stabilizing rod 3. When subjected to vibration, it can prevent the stabilizing rod 3 from moving within the adjusting slot 4. The connection position of the fixing rod 5 changes as the stabilizing rod 3 moves within the adjusting slot 4. When the stabilizing rod 3 is adjusted along the adjusting slot 4, the bolt connecting the fixing rod 5 and the stabilizing rod 3 can be loosened. After the stabilizing rod 3 is adjusted to the target position, the other end of the fixing rod 5 is reconnected to the fixing hole 6 at the corresponding position of the stabilizing rod 3 to ensure that the fixing rod 5 can always form an effective support with the stabilizing rod 3.

[0029] It should be noted that the position design of the aforementioned fixing hole 6 matches the adjustment range of the adjustment strip hole 4: when the stabilizer rod 3 slides to different positions along the adjustment strip hole 4 of the insulating frame, there will always be at least one fixing hole 6 that can be aligned with the bolt hole at the end of the fixing rod 5, ensuring that the fixing rod 5 can form an effective connection with the stabilizer rod 3 at any time.

[0030] Please refer to Figure 1 and Figure 2 In some embodiments of this example, the first limiting member includes a pull rod 7, which is a U-shaped structure. The arc-shaped part of the U-shaped structure abuts against the outer wall of the utility pole, and the U-shaped structure extends into a pre-drilled through hole on the insulation frame. Both ends of the outer wall of the U-shaped structure are provided with external threads.

[0031] In this embodiment, the arc-shaped portion of the U-shaped tie rod 7 has a flat cross-section, which forms a surface contact with the utility pole, thus distributing the fixing pressure more evenly. The U-shaped tie rod 7 forms a two-point connection with the insulation frame by passing through holes at both ends of the insulation frame and tightening nuts. Compared with the traditional single-point connection, this can more evenly transfer the load of the conductor weight, wind force, etc. borne by the insulation frame to the utility pole, avoiding local deformation or breakage of the insulation frame due to concentrated force at a single point.

[0032] Please refer to Figure 1 and Figure 2 In some embodiments of this example, the first limiting member further includes a top block 8 disposed on the insulating bracket. The top block 8 has an arc-shaped groove on the side away from the insulating bracket. The arc-shaped groove can abut against the outer wall of the utility pole. A circular locking space 9 is formed between the top block 8 and the pull rod 7.

[0033] In this embodiment, the top block 8 has a block-like structure, with an arc-shaped groove machined on the side away from the insulating support. The radius of curvature of the arc-shaped groove matches the radius of curvature of the arc-shaped part of the U-shaped pull rod 7, and the two together form a circular outline that fits the outer diameter of the utility pole. During installation, the arc-shaped part of the U-shaped pull rod 7 is first attached to the outer wall of one side of the utility pole, and then the arc-shaped groove of the top block 8 is aligned with the outer wall of the other side of the utility pole, so that the top block 8 and the U-shaped pull rod 7 form an initial wrap from both sides of the utility pole. The contact between the arc-shaped groove and the surface of the utility pole can restrict the sliding of the top block 8 along the pole body, laying the foundation for the subsequent formation of a stable locking space 9.

[0034] Please refer to Figure 1 and Figure 2 In some embodiments of this example, the second limiting member includes two locking plates 10, the ends of the two locking plates 10 are connected by bolts, and a receiving space 11 for accommodating the utility pole is formed between the two locking plates 10. A mounting post 12 is provided on the outer side wall of any locking plate 10, and the end of the stabilizing rod 3 away from the insulating frame is connected to the mounting post 12.

[0035] In this embodiment, the two locking plates 10 are generally arc-shaped plate structures, with the radius of curvature of the arc adapted to the outer diameter of a common utility pole, and the arc-shaped openings of the two locking plates 10 are arranged opposite each other. Bolt holes are machined at both ends of each locking plate 10, with the hole diameter matching the specifications of the connecting bolts. During installation, the two locking plates 10 are attached to both sides of the utility pole, so that the arc-shaped inner wall is in close contact with the outer wall of the utility pole. At this time, the arc-shaped structures of the two locking plates 10 together form an "annular receiving space 11" to accommodate the utility pole, and the bolt holes at both ends are aligned with each other, preparing for subsequent fixing.

[0036] Please refer to Figure 2 In some embodiments of this example, an anti-slip layer 13 is provided on the side of any of the locking plates 10 that contacts the utility pole.

[0037] In this embodiment, the anti-slip layer 13 is made of an insulating material with a high coefficient of friction and high elasticity, including but not limited to nitrile rubber, silicone rubber or modified epoxy resin composite material, etc. Dense micro-elastic protrusions are distributed on the surface of the anti-slip layer 13. The protrusions have a certain elastic deformation capability, which can adapt to the slight unevenness of the surface of the utility pole and enhance the fit.

[0038] Please refer to Figure 1 In some embodiments of this example, a washer 14 is provided between the ceramic insulator 2 and the insulating frame.

[0039] In traditional direct connections, the rigid contact between the metal fittings of the ceramic insulator 2 and the insulation frame easily leads to wear on both components: on the one hand, the edges of the mounting holes in the insulation frame may crack due to the bolt tightening force; on the other hand, the insulating ceramic body of the ceramic insulator 2 may develop micro-cracks due to excessive local pressure, which can easily lead to insulation failure after long-term use. The addition of the washer 14 can prevent direct rigid contact between the two components through elastic buffering and pressure dispersion, reducing the risk of wear and damage.

[0040] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
