Description

Technical Field

[0001] This invention belongs to the technical field of composite insulator processing equipment, specifically relating to an auxiliary dismantling device for composite insulators. Background Technology

[0002] Composite insulators are the core insulation components of high-voltage and ultra-high-voltage transmission lines. With their excellent resistance to flashover, light weight, high mechanical strength, and excellent long-term anti-aging properties, they are widely used in various power grid transmission projects and are key equipment to ensure the safe and stable operation of transmission lines.

[0003] A typical composite insulator structure mainly consists of an insulating core rod that supports the entire structure, a polymer sheath covering the outside of the insulating core rod, and connecting hardware fixed to both ends of the insulating core rod for equipment installation and mechanical load-bearing. After the composite insulator reaches the end of its service life or fails, it needs to be recycled and dismantled to achieve the classified recycling and reuse of materials such as metal hardware, fiberglass core rod, and polymer sheath, reducing the operation and maintenance costs of power equipment and minimizing solid waste pollution.

[0004] Chinese patent CN119566034A discloses a composite insulator recycling device and its working method. This device uses a cutting tool at the end of a cutting robot, in conjunction with an insulator fixing mechanism, to cut and separate the shed portion along the insulator's axis. Then, the insulator with the shed removed is further separated by cutting the fiberglass rod and metal head. Finally, a sorting robot completes the sorting and recycling of each component. However, this existing technology has problems in practical use: after disassembly, the shed, fiberglass rod, and metal head of the insulator are randomly piled and mixed together, greatly increasing the difficulty of subsequent manual and mechanical sorting operations, resulting in low sorting efficiency and poor sorting accuracy. Furthermore, the overall equipment integrates a large number of precision robots and multiple sets of linkage control components, resulting in a complex structure and high manufacturing cost. Long-term high-frequency operation of precision components easily leads to problems such as jamming and misalignment, making it difficult to adapt to large-scale, routine composite insulator recycling and disassembly operations. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and solve the problems mentioned in the above-mentioned technical background.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an auxiliary dismantling device for composite insulators, comprising a main platform, on which cutting saw tables are symmetrically arranged on the left and right sides, and saw bases are fixedly arranged on the upper front sides of the two cutting saw tables. A table saw is fixedly arranged on the top of the saw base, and saw blades are arranged on the side of the two table saws that are close to each other. There is an open space between the rear side of the saw blade and the rear side of the saw base. A translation platform is fixedly arranged in the middle of the main platform, and a separation platform is arranged above the translation platform. A moving mechanism for moving the separation platform back and forth is arranged between the separation platform and the translation platform. Positioning mechanisms for fixing composite insulators are arranged on the left and right sides of the separation platform. A flat cutting mechanism that moves left and right along the separation platform is arranged behind the positioning mechanism. A cutter is arranged on the side of the flat cutting mechanism that is close to the positioning mechanism.

[0007] Preferably, the separation platform is positioned between the cutting saw table and the saw blade, and the separation platform enters the cutting saw table through the open space between the rear side of the saw blade and the rear side of the saw base. This achieves precise docking of the radial cutting station.

[0008] Preferably, a housing is provided on the outer side of the translation stage, and the moving mechanism is located inside the housing. The housing protects the moving mechanism and prevents cutting debris and dust from entering the mechanism and causing jamming or malfunction.

[0010] Preferably, guide rails are fixedly provided on both sides of the groove, and the bottom of the separation platform is slidably engaged with the outside of the guide rails via guide blocks.

[0013] Preferably, a support cylinder is fixedly provided on the side of the positioning mechanism away from the cover plate to support the end of the composite insulator.

[0014] Preferably, the flat cutting mechanism includes a support leg, and an adjusting component for adjusting the extension length of the cutter is provided between the cutter and the support leg. This allows for adjustment of the cutter's cutting depth according to the size of insulators of different specifications, resulting in greater adaptability.

Detailed Implementation

[0028] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0029] Please see Figure 1 A composite insulator auxiliary dismantling device includes a main platform 100. Cutting saw tables 101 are symmetrically installed on the left and right sides of the main platform 100. Saw bases 1011 are fixedly connected to the upper front side of each of the two cutting saw tables 101. A table saw 1012 is fixedly mounted on the top of the saw base 1011. Saw blades 1013 are set on the opposite side of the two table saws 1012. The rear side of the saw blade 1013 and the rear side of the saw base 1011 form an open passage space, providing clearance space for the work position switching of the separation table 300.

[0030] A translation stage 200 is fixedly installed in the middle of the main platform 100. The translation stage 200 is encapsulated in a housing 201 on the outside. A moving mechanism 202 is installed inside the housing 201. A separation stage 300 is assembled above the translation stage 200 via the moving mechanism 202. The overall height of the separation stage 300 is between the cutting saw table 101 and the saw blade 1013. It can smoothly enter the cutting saw table 101 through the open space to complete the radial cutting operation.

[0031] like Figure 2 As shown, in another embodiment, the moving mechanism 202 includes a support plate 2021 fixed to the bottom of the housing 201. A groove is formed in the middle of the support plate 2021, and a drive motor 2023 is fixedly installed inside the groove. The output shaft of the drive motor 2023 is connected to a drive screw 2024 along the length of the groove. A matching sleeve 2026 is fixedly installed at the bottom of the separation platform 300, and the sleeve 2026 is threaded onto the outside of the drive screw 2024. Guide rails 2022 are fixedly installed on the left and right sides of the groove. A guide block 2025 is fixedly installed at the bottom of the separation platform 300, and the guide block 2025 is slidably engaged with the outside of the guide rails 2022. The drive motor 2023 drives the drive screw 2024 to rotate, and through threaded transmission, drives the sleeve 2026 to move the separation platform 300 back and forth. The cooperation between the guide rails 2022 and the guide block 2025 ensures smooth movement.

[0032] like Figure 3-6 As shown, in another embodiment, positioning mechanisms 301 are symmetrically installed on the left and right sides of the separation platform 300. Each positioning mechanism 301 includes a cylindrical base 3011. Hollow cover plates 3012 are fixedly assembled at opposite ends of the two cylindrical bases 3011. Multiple sets of limiting grooves 30121 are evenly formed on the inner side of the cover plates 3012. A chassis 3013 is rotatably mounted inside the cylindrical bases 3011 via bearings. Multiple sets of guide strips 30131 are fixed to the end face of the chassis 3013. Positioning pieces 3014, matching the number of guide strips 30131, are provided between the chassis 3013 and the cover plates 3012. One side of the positioning piece 3014 is fixed with a limiting pin 30141, which is slidably inserted into the limiting groove 30121. The other side of the positioning piece 3014 is fixed with a guide head 30142, which is slidably engaged with the outside of the guide strip 30131. The inner side of the positioning piece 3014 integrates a clamp 30143 for clamping the insulator connecting hardware.

[0033] Furthermore, a driven gear 30132 is fixedly mounted on the side of the chassis 3013 facing away from the cover plate 3012, and a positioning motor 3015 is fixedly mounted on the rear side of the positioning mechanism 301. The output end of the positioning motor 3015 is connected to the driving gear 30151 through a reduction assembly, and the driving gear 30151 and the driven gear 30132 mesh with each other.

[0034] After the positioning motor 3015 starts, it drives the chassis 3013 to rotate via gear transmission. The guide bar 30131 rotates with the chassis 3013, and in conjunction with the limiting groove 30121, it guides the limiting pin 30141 to move synchronously towards the center, thus achieving adaptive clamping and fixing of the hardware connecting the two ends of the composite insulator. When it is necessary to unlock, simply drive the positioning motor 3015 to rotate in the opposite direction.

[0035] Furthermore, a support cylinder 302 is fixedly mounted on the outside of the positioning mechanism 301 to provide auxiliary support for the end of the insulator, thereby further improving the stability of the fixation.

[0036] like Figure 7 As shown, in another embodiment, a horizontally movable flat cutting mechanism 400 is mounted on the rear side of the positioning mechanism 301. The flat cutting mechanism 400 includes a support leg 402, and an adjustment component 403 is mounted on the top of the support leg 402. The adjustment component 403 includes a strip-shaped tube 4031, and a retainer 4032 is slidably mounted inside the strip-shaped tube 4031. The retainer 4032 detachably fixes the cutter 401, and a fixing screw seat 4033 is mounted on the outer side of the strip-shaped tube 4031. The extension length of the cutter 401 can be adjusted by sliding the retainer 4032. After adjustment, the fixing screw seat 4033 locks and positions the cutter, adapting to the cutting requirements of insulators of different specifications. The flat cutting mechanism can also be moved by a motor-driven lead screw.

[0037] Furthermore, adjustment components can be provided between the cutting saw table 101 and the main platform 100, and between the positioning mechanism 301 and the separation table 300, to adjust the distance between the two cutting saw tables 101 and the two positioning mechanisms 301. The adjustment components can adopt existing technologies such as sliding table structure or screw structure to disassemble different types of composite insulators and increase the applicability of the device.

[0038] The specific workflow of this invention is as follows: The composite insulator to be disassembled is placed between the left and right positioning mechanisms 301. The hardware connecting the two ends of the insulator is placed inside the positioning plate 3014. The positioning motor 3015 is started, and the chassis 3013 is rotated through gear transmission. This drives multiple positioning plates 3014 to retract synchronously, clamping the hardware at both ends of the insulator. The support cylinder 302 is used to complete the overall fixation of the insulator. Adjust the extension length of the cutter 401 according to the insulator specifications and lock it. Control the flat cutting mechanism 400 to move horizontally along the separation table 300, drive the cutter 401 to move along the insulator axis, accurately cut the polymer umbrella sleeve covering the outside of the insulating core rod, separate the umbrella sleeve from the inner insulating core rod, and complete the disassembly of the outer polymer component. After the axial cutting is completed, the drive motor 2023 of the moving mechanism 202 is started, which drives the drive screw 2024 to rotate and drives the separation table 300 to move forward along the guide rail 2022. This allows the fixed insulator to enter the cutting saw table 101 station through the open space behind the saw blade 1013. The two table saws 1012 are started, and the saw blade 1013 cuts along the radial direction of the insulating core rod, cutting off and separating the insulating core rod from the connecting hardware at both ends. After cutting, the components are separated in an orderly manner without any mixing or accumulation. The unloading can be completed by releasing the positioning mechanism 301. Then, the moving mechanism 202 and the flat cutting mechanism 400 are reset to wait for the next disassembly operation.
