Description

Technical Field

[0001] The invention relates to the technical field of electric power working tools, and in particular to a tool for disassembling and assembling insulator pins in blind areas of vision. Background Art

[0002] In the maintenance and overhaul of power equipment, the disassembly and assembly of insulator pins is a common but challenging task. Due to the special location of some insulators and the presence of blind spots, traditional disassembly and assembly tools often face many difficulties in operation, which is not only inefficient but also may increase operational risks.

[0003] At present, the tools for disassembling and assembling insulator pins in blind areas of vision mainly consist of traditional insulating operating rods and simple clamps. The insulating operating rod is usually made of high-strength insulating material and its length can be adjusted to adapt to different working heights. The clamp is generally fixed to one end of the operating rod by threaded connection or bayonet connection to clamp the insulator pin. Signal transmission mainly relies on the operator's visual and tactile feedback. The operator judges whether the pin is accurately aligned by observing the position of the operating rod and the state of the clamp, and then transmits force through manual operation to disassemble and assemble the pin.

[0004] In order to ensure the reliable operation of the power system, the operation and maintenance of equipment are becoming more and more sophisticated. The disassembly and assembly of insulator pins needs to be accurate and efficient to ensure the normal performance of the insulators. The following problems exist when using existing insulator pin disassembly and assembly tools to perform blind operations in blind areas of vision:

[0005] Inaccurate positioning: In the blind spot of vision, it is difficult for the operator to accurately judge the position of the pin, resulting in the inability of the fixture to accurately align with the pin, increasing the difficulty and time of the operation.

[0006] Inconvenient operation: As the operating lever is long and rigid, it is not flexible to operate in a small space, and it is difficult to adjust the angle and direction, which affects the operating efficiency.

[0007] Poor stability: The clamping force of the existing clamp on the pin is not stable enough, and it is easy to loosen or fall off during operation, causing the pin to fall and damage the insulator or cause a safety accident.

[0008] Lack of feedback mechanism: Operators cannot timely understand the force conditions and latch status during operation, which may easily affect the operation effect due to excessive or insufficient force.

[0009] The reason for the positioning problem is mainly due to the lack of effective auxiliary positioning means, which relies solely on the operator's experience and feeling to make judgments, which is prone to errors. The inconvenience of operation is mainly because the design of the existing operating lever does not fully consider the special needs of blind spots and narrow spaces, and is insufficient in flexibility and operability. The poor stability is because the design of the fixture is not reasonable, the clamping force is insufficient and it is easily affected by external factors such as vibration and external force interference. The lack of feedback mechanism is due to the fact that the existing technical feedback device cannot provide real-time operation information to the operator.

[0010] In summary, due to the development of power systems, equipment layout issues, increased operation and maintenance requirements, safety factors, and limitations of existing tools, it has become an urgent need to develop a tool for disassembling and assembling insulator pins in blind areas of vision.
