Description

Technical Field

[0001] This invention relates to the field of power substation equipment maintenance technology, and in particular to a device for disassembling rainproof caps for transformer bushing oil tanks. Background Technology

[0002] In existing technologies, the removal of rain caps from COT-type bushings of power equipment transformers is typically done using pipe wrenches or adjustable chain wrenches. Because the outer edge of the rain cap is curved and smooth, it is prone to slipping, making removal difficult and often taking over 1.5 hours per operation. Furthermore, forcibly applying force can easily deform the cap and damage the sealing ring, leading to risks of oil leaks or water ingress later on. The operation requires two people: one to hold the bushing and the other to apply force, posing a safety hazard of tools falling and injuring equipment or personnel. In addition, the rain cap differs significantly in size from conventional bushing accessories, resulting in poor compatibility with existing tools, and frequent tool changes further reduce operational efficiency.

[0003] Therefore, a device is needed to disassemble the rain cap of the COT type bushing of power equipment transformer. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a disassembly device for the rainproof cap of the transformer bushing oil tank, which can quickly complete the installation and disassembly of the COT type bushing rainproof cap of the power equipment transformer, significantly improving the work efficiency; the structure is simple, the adaptability is wide and the portability is certain.

[0006] One side of the curved bonding surface is fitted with an oil-resistant rubber pad, which is tightly bonded to the curved clamp body with strong adhesive.

[0007] This also includes: multiple tapered screws, which pass through the arc-shaped clamp body and the oil-resistant rubber pad in sequence. The pins at the ends of the tapered screws press against the outer wall of the casing oil conservator rainproof cap, further locking the relative position between the two clamp assemblies and the casing oil conservator rainproof cap.

[0008] The handle can be folded and stowed relative to the ear plate, and the outside of the handle is equipped with an insulating and non-slip sleeve.

[0009] The pins pass through the handle and the ear plate respectively, connecting the handle to the clamp assembly.

[0010] The two clamp components are designed to be symmetrical, and the arc-shaped clamp body is integrally formed from high-strength alloy material.

[0011] The disassembly device for the rainproof cap of the transformer bushing oil conservator according to the present invention has the following beneficial effects: The clamp assembly includes: an arc-shaped clamp body, an arc-shaped contact surface on one side of the arc-shaped clamp body, fastening plates extending from opposite sides of the arc-shaped contact surface, and an ear plate on the opposite side of the arc-shaped clamp body; and a handle rotatably mounted on the ear plate; wherein: two clamp assemblies are assembled on opposite sides of the outside of the rainproof cap of the transformer bushing oil conservator, and two bolts are fastened by passing through the ear plates on opposite sides of the two clamp assemblies respectively; the arc-shaped contact surface of the arc-shaped clamp body of the two clamp assemblies is attached to the outer edge of the rainproof cap of the bushing oil conservator; wherein: the relative positions of the two clamp assemblies and the rainproof cap of the bushing oil conservator are locked; by gripping the two handles of the two clamp assemblies and rotating them, the friction between the two clamp assemblies and the rainproof cap of the bushing oil conservator drives the rainproof cap of the bushing oil conservator to rotate, thereby disassembling the rainproof cap of the bushing oil conservator under uniform force. It can quickly complete the installation and removal of COT type bushing rain caps for power equipment transformers, significantly improving work efficiency; it has a simple structure, wide adaptability and a certain degree of portability.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] like Figures 1-2 The image shows a first embodiment of the disassembly device for the rainproof cap of the transformer bushing oil tank according to the present invention.

[0017] The disassembly device for the rainproof cap of the transformer bushing oil conservator in this embodiment of the invention includes: two clamp assemblies 1, each clamp assembly 1 including: an arc-shaped clamp body 11, an arc-shaped fitting surface 112 on one side of the arc-shaped clamp body 11, fastening plates 114 extending from opposite sides of the arc-shaped fitting surface 112, and an ear plate 110 on the opposite side of the arc-shaped clamp body 11; and a handle 19 rotatably mounted on the ear plate 110.

[0018] Among them: the two clamping assemblies 1 are assembled on opposite sides of the outside of the transformer bushing oil conservator rainproof cap T, and the two bolts A are fastened by passing through the fastening plates 114 on opposite sides of the two clamping assemblies 1 respectively. The arc-shaped contact surface 112 of the arc-shaped clamping body 11 of the two clamping assemblies 1 is attached to the outer edge of the bushing oil conservator rainproof cap T.

[0019] Specifically: the two clamp assemblies 1 are locked in relative position with the casing oil conservator rainproof cap T. The two handles 19 of the two clamp assemblies are gripped and rotated. The friction between the two clamp assemblies 1 and the casing oil conservator rainproof cap T drives the casing oil conservator rainproof cap T to rotate, so as to disassemble the casing oil conservator rainproof cap T with uniform force.

[0020] In specific implementation, the two clamp components 1 are designed to be symmetrical. The clamp component 1 includes: an arc-shaped clamp body 11, which is integrally formed from high-strength alloy material. One side of the arc-shaped clamp body 11 is provided with an arc-shaped fitting surface 112, and the opposite side of the arc-shaped clamp body 11 is provided with an ear plate 110. The handle 19 is rotatably mounted on the ear plate 110.

[0022] Preferably, an oil-resistant rubber pad 1120 is attached to one side of the arc-shaped contact surface 112. The oil-resistant rubber pad 1120 has the same area as the inner ring of the arc-shaped contact surface 112 and is tightly attached to the arc-shaped clamp body 11 with strong adhesive. The purpose of this arrangement is to both enhance friction to prevent slippage and avoid scratching the cap body.

[0023] Furthermore, the fastening plate 114 extends to the opposite sides of the arc-shaped mating surface 112, and the fastening plate 114 is provided with screw holes, the function of which is to connect and assemble the two clamp assemblies 1 by means of screw fastening.

[0025] During implementation, the tapered screw 2 is an M12*30mm screw with a tapered tip. After the two clamp assemblies 1 are locked to the rainproof cap T of the sleeve oil conservator, the adjusting pin 21 of the tapered screw 2 can be pressed against the outer wall of the rainproof cap T of the sleeve oil conservator to further lock the relative position between the two structures and prevent slippage during disassembly. Furthermore, a handle 19 is installed at one end of the arc-shaped clamp body 11. In this embodiment, the handle 19 is made of metal and can be folded and stored relative to the ear plate 110. An insulating anti-slip sleeve is installed on the outside of the handle 19.

[0026] During implementation, pins 3 pass through handle 19 and ear plate 110 respectively, connecting handle 19 to clamp assembly 1. The two handles 19 on the two clamp assemblies 1 are designed to be symmetrical.

[0027] In the embodiment of the present invention, the disassembly device for the rainproof cap of the transformer bushing oil conservator is operated by two people holding the handles on both sides and rotating clockwise in sync. The friction between the two clamp components 1 and the rainproof cap T of the bushing oil conservator drives the cap body to rotate, achieving uniform force disassembly. No additional personnel are required to fix the bushing, reducing coordination errors and safety hazards.

[0028] Furthermore, the weight of the disassembly device for the rainproof cap of the transformer bushing oil conservator in this application is controlled within 5kg, and the opening and closing range of the clamp assembly 1 is compatible with a wide range of rainproof cap diameters, which can quickly complete the installation and disassembly of rainproof caps of various specifications, significantly improving work efficiency.
