Description

Technical Field

[0001] This invention relates to the field of electrical engineering technology, and in particular to a disassembly device for a cylindrical head iron cap type insulator. Background Technology

[0002] As a core component of overhead transmission lines, the stability of the connection between the iron cap, glass body, and steel feet of glass insulators directly affects the safe operation of the power system. During long-term service, the iron cap is prone to corrosion, external impact, or insulator spontaneous explosion, requiring individual disassembly and replacement. Improper disassembly can easily cause damage to the glass body or line outage. Therefore, efficient and safe iron cap disassembly tools are a key requirement for transmission line maintenance.

[0003] In the prior art, devices for the disassembly and assembly of glass insulators have been developed. For example, utility model patent application number 201820144784.9 discloses a glass insulator replacement device. This device uses two parallel clamps with locking holes to fit onto the iron cap of the insulator. The clamps are driven to move relative to each other by connecting rods with opposite thread directions at both ends, so as to replace the damaged insulator in situ. Its structure is simple and convenient to transport, effectively solving the problems of traditional replacement methods that rely on multiple sets of auxiliary tools and are cumbersome to operate. However, this device is mainly used for replacing the entire insulator and does not have a special structure designed for the separation of the iron cap and the glass body. When disassembling the iron cap, uneven force can easily cause damage to the components. In addition, the compatibility of the locking holes is limited, making it difficult to meet the precise clamping requirements of iron caps of different specifications. Another related technology, such as the invention patent application with application number 202310051049.9, discloses a device and its manufacturing method for quickly fixing or disassembling overhead transmission lines. This type of device achieves rapid assembly and disassembly of line components through clamping structures or magnetic components, significantly improving work efficiency. Some structures also have anti-loosening designs, making them suitable for complex transmission line scenarios. However, this device focuses on the general fixing and disassembly of the overall components of the overhead line, without considering the special structural characteristics of the glass insulator cap—such as its spherical outline, hot-dip galvanized surface, and close fit with the glass body. This results in insufficient adaptability when disassembling the cap, leading to problems such as low operational precision and easy scratching of the cap surface. It cannot meet the refined requirements for individual disassembly of the insulator cap. In summary, existing technologies either focus on the overall replacement of insulators or on the general assembly and disassembly of line components, but neither has designed a dedicated disassembly mechanism for the structural characteristics of glass insulator caps. This results in poor adaptability, low disassembly efficiency, and easy damage to components, making it difficult to meet the actual needs for rapid, accurate, and safe disassembly of caps during transmission line maintenance. Summary of the Invention

[0004] The main objective of this invention is to provide a disassembly device for cylindrical head iron cap insulators. This device aims to solve the technical problems of the iron cap structure of bell-shaped DC disc insulators differing from that of AC insulators, and the outer side of the iron cap having a zinc ring for corrosion protection. If existing clamps are used to directly apply force to the zinc ring, it is easy to cause deformation and damage to the zinc ring, resulting in loss of corrosion protection function. If the "clamping the raised edge" solution is used, it cannot be implemented because the iron cap of bell-shaped DC insulators does not have a suitable raised edge structure.

[0005] To achieve the above-mentioned objectives, the present invention proposes a disassembly device for a cylindrical head iron cap insulator, comprising two clamping bodies. The two clamping bodies include a first clamping seat and a second clamping seat for enclosing and forming a locking hole that is sleeved on the outside of the iron cap, a first connecting seat provided on the first clamping seat and a second connecting seat provided on the second clamping seat, and the clamping body further includes a wedge-shaped clamping block, a pulling block and a connecting rope. The wedge-shaped clamping blocks are respectively disposed on the first clamping seat and the second clamping seat, and the pulling blocks are respectively disposed on the first connecting seat and the second connecting seat; A connecting groove is provided between the first clamp and the first connecting seat and between the second clamp and the second connecting seat. The connecting rope is movably disposed in the connecting groove, and the two ends of the connecting rope are respectively connected between the wedge-shaped clamp and the pull block. The first clamp and the second clamp are respectively provided with a first engagement slope, and the bottom of each wedge-shaped clamp is provided with a second engagement slope. The surface of the second engagement slope abuts against the surface of the first engagement slope, so that when pulled by the connecting rope, the wedge-shaped clamp moves radially inward along the locking hole under the cooperation of the first engagement slope and the second engagement slope.

[0006] Furthermore, the wedge-shaped clamping blocks are respectively located at the edge of the locking hole formed by the first clamping seat and the second clamping seat and sleeved outside the iron cap, and the pulling blocks are respectively located at one end of the first connecting seat and the second connecting seat. The locking hole formed by the first clamping seat and the second clamping seat and sleeved outside the iron cap is provided with a stepped groove.

[0007] Furthermore, the inclination angles of the first and second mating ramps are matched.

[0008] Furthermore, a clamp fixing assembly is provided between the first clamp and the second clamp. The clamp fixing assembly includes a fixing shaft, a fixing pin, a fixing screw, a nut, a screw groove, and an inner groove. The fixing shaft is fixedly installed on one side of one end of the first clamp. The fixing pin is rotatably connected to the other side of one end of the first clamp. One end of the fixing screw is fixedly connected to the middle of the fixing pin. The nut is threadedly connected to one end of the fixing screw. The screw groove and the inner groove are opened on one side of one end of the second clamp, and the inner groove is located at one end of the screw groove.

[0009] Furthermore, the fixing screw is sleeved inside the screw groove, and one end of the nut is sleeved inside the embedded groove.

[0010] Furthermore, one side of the second clamp is rotatably connected to one side of the first clamp via a fixed pivot, and the two sides of one end of the second clamp are fitted inside the two sides of one end of the first clamp.

[0011] Furthermore, the first clamp and the first connecting seat, as well as the second clamp and the second connecting seat, are all provided with a lubrication assembly. The lubrication assembly includes an opening, a mounting sleeve, an oil storage sponge, and a sealing cap. The opening is respectively opened at the mounting position of the wedge-shaped clamping block of the first clamp and the second clamp. The mounting sleeve is respectively fixedly connected to the mounting position of the pull block of the first connecting seat and the second connecting seat. The oil storage sponge is located inside the mounting sleeve, and the sealing cap is threaded to one end of the mounting sleeve.

[0012] Furthermore, the opening is connected to the connecting groove, and the oil-storing sponge abuts against the surface of the connecting rope.

[0013] Furthermore, both ends of the connecting rope are provided with sealing components. The sealing components include a first mounting groove, a second mounting groove, a sealing ring, a first fixing cover, and a second fixing cover. The first mounting groove and the second mounting groove are respectively opened at both ends of the connecting groove. The sealing ring is respectively installed inside the first mounting groove and the second mounting groove. The first fixing cover is respectively fixedly installed at the mounting position of the wedge-shaped clamping block of the first clamping seat and the second clamping seat by setting bolts. The second fixing cover is fixedly installed at the mounting position of the pull block of the first connecting seat and the second connecting seat.

[0014] Furthermore, the sealing rings are respectively fitted onto the outer walls of both ends of the connecting rope, the first fixing cover is located at the top of the first mounting groove, and the second fixing cover is located at the top of the second mounting groove.

[0015] Beneficial effects: 1. The disassembly device for cylindrical head iron cap insulators of the present invention is constructed by combining a double clamp with a connecting rope and a wedge-shaped clamping block. Using the cylindrical head as the clamping object, it completely avoids direct contact with the zinc ring, protecting its corrosion resistance. The connecting rope allows for 180° force rotation. Combined with the first and second mating inclined surfaces with matching tilt angles, the wedge-shaped clamping block can firmly clamp the iron cap when subjected to reverse force, preventing relative slippage. Furthermore, the limited space of the wedge-shaped clamping block is smaller than that of the iron cap zinc ring, preventing the insulator from falling off even if it slips accidentally. This solves the problems of existing devices being unable to clamp protruding edges and easily damaging the zinc ring, improving the safety and reliability of disassembly.

[0016] 2. The disassembly device for the cylindrical head iron cap insulator of the present invention realizes the rotational opening and closing of the first and second clamps through a fixed rotating shaft, which facilitates the quick and easy installation of the cylindrical head of the insulator and improves the operating efficiency.

[0017] 3. The disassembly device for the cylindrical head iron cap insulator of the present invention communicates with the connecting groove through the opening, continuously contacts the surface of the connecting rope, releases lubricating oil for a long time, greatly reduces the friction loss of the connecting rope moving in the groove, and extends its service life. The sealing cover can isolate outdoor rainwater and dust, prevent sponge oil from leaking or becoming damp and deteriorating, eliminates the need for frequent lubrication, reduces maintenance frequency, ensures smooth sliding of the connecting rope, avoids jamming that affects disassembly efficiency, and is especially suitable for the harsh outdoor environment of overhead lines, improves the long-term operational stability of the device, and reduces maintenance interruptions caused by friction failures.

[0018] 4. The disassembly device for the cylindrical head iron cap insulator of the present invention, by using sealing rubber rings to cover both ends of the connecting rope, can effectively prevent outdoor rainwater and dust from entering the connecting groove, avoid internal parts from rusting or being stuck by impurities, protect the core transmission structure of the device, and at the same time ensure that lubricating oil will not leak out. Furthermore, the first and second fixing covers are fixed by bolts to prevent the sealing rubber rings from falling off, ensuring a consistent sealing effect. For the outdoor high humidity and dusty environment of transmission lines, this component significantly improves the weather resistance of the device, reduces failures caused by impurities, reduces the number of maintenance, extends the overall service life of the device, and ensures the continuous reliability of the iron cap disassembly operation.

[0026] Example 1 Reference Figures 1-7 An embodiment of the present invention provides a disassembly device for a cylindrical head iron cap insulator, comprising two clamp bodies, the two clamp bodies comprising a first clamp seat 11 and a second clamp seat 21 for enclosing and forming a locking hole sleeved on the iron cap, a first connecting seat 12 disposed on the first clamp seat 11 and a second connecting seat 22 disposed on the second clamp seat 21, characterized in that the clamp body further comprises a wedge-shaped clamping block 6, a pulling block 8 and a connecting rope 4; Wedge-shaped clamping blocks 6 are respectively disposed on the first clamping seat 11 and the second clamping seat 21, and pull blocks 8 are respectively disposed on the first connecting seat 12 and the second connecting seat 22. The wedge-shaped clamping blocks 6 are respectively located at the edge of the locking hole formed by the first clamping seat 11 and the second clamping seat 21 and sleeved outside the iron cap. The pull blocks 8 are respectively located at one end of the first connecting seat 12 and the second connecting seat 22. A stepped groove 15 is opened in the locking hole formed by the first clamping seat 11 and the second clamping seat 21 and sleeved outside the iron cap. A connecting groove 3 is provided between the first clamp 11 and the first connecting seat 12 and between the second clamp 21 and the second connecting seat 22. The connecting rope 4 is movably disposed in the connecting groove 3, and the two ends of the connecting rope 4 are respectively connected between the wedge-shaped clamp 6 and the pull block 8. The first clamping seat 11 and the second clamping seat 21 are respectively provided with a first engaging inclined surface 5, and the bottom of each wedge-shaped clamping block 6 is provided with a second engaging inclined surface 7. The surface of the second engaging inclined surface 7 abuts against the surface of the first engaging inclined surface 5, so that when pulled by the connecting rope 4, the wedge-shaped clamping block 6 moves radially inward along the card hole under the cooperation of the first engaging inclined surface 5 and the second engaging inclined surface 7, and the inclination angles of the first engaging inclined surface 5 and the second engaging inclined surface 7 match. During installation, the first clamp 1 and the second clamp 2 are symmetrically fastened to the outside of the cylindrical head of the bell-shaped DC disc insulator, so that the connecting rope 4 in the connecting groove 3 fits the curvature of the cylindrical head. At this time, the second engaging inclined surface 7 of the wedge-shaped clamp 6 is in close contact with the first engaging inclined surface 5 of the clamp. By pulling the pull block 8, the connecting rope 4 can be tightened along the connecting groove 3. The clamping force is transmitted to the cylindrical head by utilizing the reverse force characteristics of the wedge-shaped clamp, and the clamp does not contact the zinc ring on the outside of the iron cap throughout the process. The function of the stepped groove 15 is to first realize the positioning of the cylindrical head iron cap insulator, give an initial force to achieve pre-fixation, and then clamp it through the two wedge-shaped clamps 6. The top of the wedge-shaped clamp 6 and the top of the inner side of the pull block 8 are provided with a cover plate. The cover plate is used to ensure aesthetics and cover the connection between the connecting rope 4 and the wedge-shaped clamp 6, as well as the connection between the connecting rope 4 and the pull block 8.

[0027] This embodiment achieves stable clamping of bell-shaped DC insulator caps without matching protruding edges. It avoids the corrosion damage caused by the direct action of existing clamps on the zinc ring. It also prevents the insulator from sliding relative to each other during disassembly by cooperating with the wedge-shaped clamp and the connecting rope 4. At the same time, the limited installation space of the wedge-shaped clamp is smaller than the size of the zinc ring of the cap, which can avoid the risk of the insulator falling off due to accidental sliding.

[0028] Optionally, the connecting rope 4 can be made of multiple flexible steel cables twisted together to improve load-bearing capacity and fit; the surface of the wedge-shaped clamping block 6 can be provided with anti-slip texture to further enhance the friction with the first mating inclined surface 5 and optimize clamping stability.

[0029] Working principle: When the first clamp 11 and the second clamp 21 are fitted onto the iron cap, the iron cap pushes the wedge-shaped clamp 6 to move. Under the synergistic action of the two mating inclined surfaces, the wedge-shaped clamp 6 will move towards the outside of the locking hole. Then, the pull block 8 on the first connecting seat 12 and the second connecting seat 22 is connected to other clamp bodies. When the pull block 8 is pulled, the wedge-shaped clamp 6 is pulled axially downward through the connecting rope 4. Under the synergistic action of the two mating inclined surfaces, the wedge-shaped clamp 6 will move towards the center of the locking hole, thereby clamping the iron head and ensuring that the insulator iron cap does not slide relative to the iron cap. Then, disassembly is carried out.

[0030] Example 2 Further improvements were made based on Example 1, with reference to... Figure 1 , Figure 2 , Figure 4 , Figure 5As shown, a clamp fixing assembly is provided between the first clamp 11 and the second clamp 21. The clamp fixing assembly includes a fixing shaft 901, a fixing pin 902, a fixing screw 903, a nut 904, a screw groove 905, and an inner groove 906. The fixing shaft 901 is fixedly installed on one side of one end of the first clamp 11. The fixing pin 902 is rotatably connected to the other side of one end of the first clamp 11. One end of the fixing screw 903 is fixedly connected to the middle of the fixing pin 902. The nut 904 is threadedly connected to the fixing pin 906. One end of the rod 903 has a screw groove 905 and an inner groove 906 on one side of the second clamp 21. The inner groove 906 is located at one end of the screw groove 905. The fixing screw 903 is sleeved inside the screw groove 905. One end of the nut 904 is sleeved inside the inner groove 906. One side of the second clamp 21 is rotatably connected to one side of the first clamp 11 through the setting of the fixing shaft 901. The two sides of one side of the second clamp 21 are sleeved inside the two sides of one side of the first clamp 11. When assembling the fixture, first rotate the second clamp 2 around the fixed pivot 901 so that it engages with the first clamp 1 on the outside of the insulator cylindrical head; then rotate the fixing pin 902 to insert the fixing screw 903 into the screw groove 905 of the second clamp 2, and tighten the nut 904 until one end of it is embedded in the inner groove 906, so that the first clamp 1 and the second clamp 2 are combined and installed.

[0031] This embodiment achieves rapid opening and closing and precise fixing of the clamp. The first clamp 1 and the second clamp 2 are rotated and opened by fixing the rotating shaft 901, which facilitates the quick and easy application of the insulator cylindrical head and improves the operation efficiency.

[0032] Optionally, the 904 nut can be a butterfly type, allowing for manual adjustment of tightness without the need for tools.

[0033] Working principle: First, rotate the second clamp 21 around the fixed pivot 901, so that it symmetrically engages with the first clamp 11 on the outside of the insulator cap, completing the initial clamping. Then, rotate the fixing pin 902 on the first clamp 11, causing the fixing screw 903 to engage in the screw groove 905 of the second clamp 21. Next, tighten the nut 904 until one end of the nut 904 is embedded in the inner groove 906 and presses the second clamp 21 tightly. Through the locking force of the thread and the cooperation of the fixed pivot 901, the first clamp 11 and the second clamp 21 form a stable enclosing structure, firmly fitted on the outside of the cap, preventing the clamp from loosening or shifting during disassembly, and providing a stable structural foundation for the subsequent clamping of the cap by the wedge-shaped clamping block 6 and the transmission of disassembly force.

[0034] Example 3 Further improvements were made based on Example 1, with reference to... Figure 4As shown, the first clamping seat 11 and the first connecting seat 12, as well as the second clamping seat 21 and the second connecting seat 22, are all provided with lubrication components. The lubrication components include an opening 1001, a mounting sleeve 1002, an oil storage sponge 1003, and a sealing cap 1004. The openings 1001 are respectively opened at the mounting positions of the wedge-shaped clamping blocks 6 of the first clamping seat 11 and the second clamping seat 21. The mounting sleeves 1002 are respectively fixedly connected to the mounting positions of the pull blocks 8 of the first connecting seat 12 and the second connecting seat 22. The oil storage sponge 1003 is located inside the mounting sleeve 1002. The sealing cap 1004 is threadedly connected to one end of the mounting sleeve 1002. The opening 1001 is connected to the connecting groove 3. The oil storage sponge 1003 abuts against the surface of the connecting rope 4. Before use, the sealing cap 1004 is opened, and lubricating oil is injected into the oil-storing sponge 1003 in the mounting sleeve 1002. After the oil-storing sponge 1003 absorbs the lubricating oil, it continuously contacts the surface of the connecting rope 4 in the connecting groove 3 through the openings 1001 at the bottom of the first clamp 1 and the second clamp 2. As the connecting rope 4 moves, the lubricating oil is evenly applied to its outer wall. After the sealing cap 1004 is tightened, it can isolate outdoor rainwater and dust, and prevent the sponge from getting damp, deteriorating, or leaking oil.

[0035] This embodiment achieves long-term lubrication between the connecting rope 4 and the connecting groove 3, significantly reducing wear caused by relative sliding between the two and extending the service life of the device; at the same time, it eliminates the need for frequent disassembly of the clamps to replenish lubricating oil, reducing the workload and difficulty of overhead line operation and maintenance.

[0036] Optionally, the oil reservoir sponge 1003 can be made of high-density polyurethane material to improve oil absorption and retention; an oil level observation window can be added to the outside of the mounting sleeve 1002 to make it easy to intuitively judge the remaining amount of lubricating oil in the oil reservoir sponge 1003 and replenish it in time.

[0037] Working principle: After absorbing lubricating oil, the oil-storing sponge 1003 continuously contacts the surface of the movable connecting rope 4 through the opening 1001 connected to the connecting groove 3. When the pull block 8 pulls the connecting rope 4 to slide back and forth in the connecting groove 3, the connecting rope 4 will cause the lubricating oil released by the oil-storing sponge 1003 to be evenly coated on its outer wall and the inner wall of the connecting groove 3. The sealing cover 1004 isolates outdoor rainwater and dust, preventing the oil-storing sponge 1003 from getting damp and deteriorating or the lubricating oil from leaking out, ensuring that the connecting rope 4 and the connecting groove 3 are always lubricated, greatly reducing the friction loss caused by the relative sliding between the two, avoiding jamming, ensuring the smooth drive of the wedge-shaped clamp 6, and improving the long-term operational stability of the device in outdoor environments.

[0038] Example 4 Further improvements were made based on Example 1, with reference to... Figure 2As shown, both ends of the connecting rope 4 are provided with sealing components. The sealing components include a first mounting groove 1101, a second mounting groove 1102, a sealing ring 1103, a first fixing cover 1104, and a second fixing cover 1105. The first mounting groove 1101 and the second mounting groove 1102 are respectively opened at both ends of the connecting groove 3. The sealing ring 1103 is respectively installed inside the first mounting groove 1101 and the second mounting groove 1102. The first fixing cover 1104 is respectively fixedly installed at the mounting position of the wedge-shaped clamping block 6 of the first clamping seat 11 and the second clamping seat 21 by setting bolts. The second fixing cover 1105 is fixedly installed at the mounting position of the pull block 8 of the first connecting seat 12 and the second connecting seat 22. The sealing ring 1103 is respectively sleeved on the outer wall of both ends of the connecting rope 4. The first fixing cover 1104 is located at the top of the first mounting groove 1101, and the second fixing cover 1105 is located at the top of the second mounting groove 1102. During assembly, the sealing ring 1103 is first embedded into the first mounting groove 1101 and the second mounting groove 1102 at both ends of the connecting groove 3, so that the inner wall of the ring is tightly attached to the outer wall of the connecting rope 4. Then, the first fixing cover 1104 is fixed to the top of the first mounting groove 1101 and the second fixing cover 1105 is fixed to the top of the second mounting groove 1102 by bolts, and the sealing ring 1103 is pressed to prevent it from shifting, thus forming a sealing structure for both ends of the connecting groove 3.

[0039] This embodiment achieves a sealed protection for the inside of the connecting groove 3, which can effectively prevent outdoor rainwater, sand and dust and other impurities from entering the groove, avoid the connecting rope 4 from rusting or being stuck by impurities, and adapt to the harsh outdoor environment of the power transmission line, improve the overall weather resistance of the device, and reduce the number of fault repairs caused by seal failure.

[0040] Optionally, the sealing ring 1103 can be made of aging-resistant EPDM rubber to extend its outdoor service life; anti-slip grooves can be provided on the surfaces of the first fixing cover 1104 and the second fixing cover 1105 to facilitate disassembly with tools for replacement and maintenance of the sealing ring 1103.

[0041] Working principle: The sealing ring 1103 is embedded in the first mounting groove 1101 and the second mounting groove 1102 at both ends of the connecting groove 3, with its inner wall tightly fitting the outer wall of the connecting rope 4. The first fixing cover 1104 and the second fixing cover 1105 are tightened with bolts to press the sealing ring 1103, forming a closed sealing structure. This structure can effectively prevent outdoor rainwater, sand and dust and other impurities from entering the interior of the connecting groove 3, avoiding corrosion of the connecting rope 4 and jamming of internal transmission parts; at the same time, it prevents the leakage of lubricating oil in the connecting groove 3, ensuring the long-term lubrication effect of the lubrication components. Through dual protection, it is suitable for the harsh environment of high humidity and dust in outdoor power transmission lines, extends the service life of the core transmission structure of the device, and reduces maintenance failures caused by seal failure.

[0042] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
