[0026] like Figure 1As shown, in this embodiment, the spacer rod operating device is characterized by including: a drive worm 10, a sleeve 20, a connecting seat 30, a turbine structure 40, an ejector rod 50, a clutch mechanism 60, a clamping cylinder 71, a threaded structure 72, and a retaining mechanism 73. The drive worm 10 is rotatably disposed within the sleeve 20. The connecting seat 30 is connected to the sleeve 20. The turbine structure 40 is rotatably connected to the connecting seat 30 and meshes with the drive worm 10. The first end of the ejector rod 50 is connected to the turbine structure 40, and the second end of the ejector rod 50 is a free end. The clutch mechanism 60 is disposed between the end of the drive worm 10 and the connecting seat 30. The clutch mechanism 60 has a first synchronous motion state and a first disengaged state. When the clutch mechanism 60 is in the first synchronous motion state, the clutch mechanism 60 drives the worm 10 to move synchronously with the sleeve 20 via the clutch mechanism 60. The clamping cylinder 71 is movably disposed on the sleeve 20. The threaded structure 72 is disposed between the sleeve 20 and the clamping cylinder 71. The retaining mechanism 73 is disposed between the sleeve 20 and the clamping cylinder 71. The retaining mechanism 73 has a second synchronous motion state and a second separation state. When the retaining mechanism 73 is in the second synchronous motion state, the sleeve 20 and the clamping cylinder 71 are relatively stationary. When the retaining mechanism 73 is in the second separation state, the sleeve 20 and the clamping cylinder 71 can rotate relative to each other. Specifically, when the clutch mechanism 60 is in the first separation state, the retaining mechanism 73 is in the second synchronous motion state. When the clutch mechanism 60 is in the first synchronous motion state, the retaining mechanism 73 is in the second separation state.

[0027] Applying the technical solution of this embodiment, the driving worm 10 is rotatably inserted into the sleeve 20, the connecting seat 30 is connected to the sleeve 20, the turbine structure 40 is rotatably connected to the connecting seat 30 and can engage with the driving worm 10, the first end of the ejector rod 50 is connected to the turbine structure 40, the clutch mechanism 60 is arranged between the driving worm 10 and the connecting seat 30, the clutch mechanism 60 has a first synchronous motion state and a first separation state, the clamping cylinder 71 is movably arranged on the sleeve 20, the threaded structure 72 is arranged between the sleeve 20 and the clamping cylinder 71, the holding mechanism 73 is arranged between the sleeve 20 and the clamping cylinder 71, the holding mechanism 73 has a second synchronous motion state and a second separation state, specifically, when the clutch mechanism 60 is in the first separation state, the holding mechanism 73 is in the second synchronous motion state, and when the clutch mechanism 60 is in the first synchronous motion state, the holding mechanism 73 is in the second separation state. Through the above arrangement, when the drive worm 10 rotates, it can drive the turbine structure 40 to rotate, thereby causing the ejector rod 50 to swing and extend toward one side of the sleeve 20. When the drive worm 10 continues to rotate and causes the clutch mechanism 60 to switch from the first separation state to the first synchronous motion state, the retaining mechanism 73 to switch from the second synchronous motion state to the second separation state. At this time, the clamping cylinder 71 can move toward the ejector rod 50 under the action of the threaded structure 72, thereby clamping the spacer rod. This operation method is relatively simple and can effectively drive the spacer rod. Therefore, the technical solution of this embodiment effectively solves the problem of difficult spacer rod assembly and disassembly in the related art.

[0028] This design enables the operating device to achieve precise operation of the spacer rods by switching the clutch mechanism 60 and the retaining mechanism 73. It is particularly suitable for power line maintenance scenarios where the position of the spacer rods needs to be frequently adjusted, thereby improving work efficiency and operational flexibility.

[0029] In practical applications, this operating device can significantly reduce the time required for maintenance and lower maintenance costs. At the same time, its precise operating capabilities can effectively avoid line failures caused by improper operation and improve the operational stability of the line.

[0030] like Figure 1 and Figure 2 As shown, in this embodiment, a relief recess 31 is provided on the connecting seat 30, and the clutch mechanism 60 is disposed between the relief recess 31 and the driving worm 10. The design of the relief recess 31 provides sufficient space for the clutch mechanism 60, enabling the clutch mechanism 60 to operate more smoothly and reducing resistance during operation. This is suitable for scenarios requiring operation in a narrow space, improving the adaptability of the device and the convenience of operation.

[0031] During power line maintenance, especially when operating among dense cables, the design of the avoidance recess 31 enables the operating device to better adapt to narrow spaces, improves operational flexibility and efficiency, avoids possible cable damage during operation, and ensures safe operation of the power line.

[0032] like Figure 1 and Figure 2 As shown, in this embodiment, the clutch mechanism 60 includes a nut 61 and a threaded segment 62. The threaded segment 62 is disposed on the side of the relief recess 31 facing the drive worm 10. When the drive worm 10 rotates, the threaded segment 62 is threadedly engaged with the nut 61, and the nut 61 is able to abut and engage with the side of the relief recess 31 facing the nut 61. The cooperation between the threaded segment 62 and the nut 61 enables precise control of the clutch mechanism 60, allowing the operator to easily switch the operating state of the clutch mechanism 60 as needed. This is suitable for scenarios requiring fine-tuning and fixing of the spacer rods, improving operational accuracy and efficiency.

[0033] The above-mentioned fine-tuning and fixing capabilities are extremely important in the installation and adjustment of power lines. They can ensure the position accuracy of the spacer bars, avoid power line failures caused by improper spacer bar positioning, and improve the reliability and safety of the power system.

[0034] like Figure 1 and Figure 3 As shown, in this embodiment, the retaining mechanism 73 includes a magnetic member 731 and a magnetic member 732. One of the magnetic member 731 and the magnetic member 732 is disposed on the sleeve 20, and the other of the magnetic member 731 and the magnetic member 732 is disposed on the clamping cylinder 71. The coordinated use of the magnetic member 731 and the magnetic member 732 simplifies the structure of the retaining mechanism 73, making the connection and separation between the clamping cylinder 71 and the sleeve 20 more convenient and quick. This is suitable for power line maintenance scenarios that require frequent installation and removal of spacer bars, greatly improving operational convenience and efficiency.

[0035] In practical applications, the cooperation between the magnetic part 731 and the magnetic attraction part 732 can achieve rapid connection and separation, reduce the labor intensity of the operator, and improve work efficiency. Especially in emergency situations, the position of the spacer rod can be quickly adjusted to ensure the stable operation of the power line.

[0036] like Figure 1 and Figure 3 As shown, in this embodiment, the spacer rod operating device further includes a bearing member 74. The inner ring of the bearing member 74 is connected to the drive worm 10, and the outer ring of the bearing member 74 is connected to the sleeve 20. The provision of the bearing member 74 reduces friction between the drive worm 10 and the sleeve 20, thereby improving the stability and service life of the device, making it suitable for scenarios of long-term continuous operation and ensuring continuous and reliable operation.

[0037] In power line maintenance, the use of bearing member 74 can reduce energy loss during operation and improve the efficiency of the operating device. At the same time, its good stability ensures the safety and reliability of long-term continuous operation. It is suitable for large-scale power line maintenance work and reduces the maintenance cost of equipment.

[0038] like Figure 1 As shown, in this embodiment, the spacer rod operating device further includes a friction-reducing structure 75, which is disposed on the clamping cylinder 71. The friction-reducing structure 75 includes a mounting seat 751 and a plurality of rolling balls 752 disposed on the mounting seat 751. The plurality of rolling balls 752 are spaced apart on a side of the mounting seat 751 facing the connecting seat 30, with each rolling ball 752 protruding from the mounting seat 751. The provision of the friction-reducing structure 75 further reduces friction between the clamping cylinder 71 and the connecting seat 30, thereby improving the smoothness of operation and the flexibility of the device. It is suitable for scenarios where the spacer rods need to be operated at different angles and directions, ensuring the accuracy and stability of the operation.

[0039] In actual operation, the friction-reducing structure 75 can enable the operating device to remain stable and efficient in a complex working environment. Especially in scenarios where the angle and direction of the spacer rod need to be adjusted, the friction-reducing structure can improve the flexibility and accuracy of operation, reduce operational errors, and improve the quality of power line maintenance.

[0040] like Figure 1 As shown, in this embodiment, the cross-sectional area of ​​the clamping tube 71 gradually increases from the connecting base 30 to the clamping tube 71. This design allows the clamping tube 71 to better adapt to spacer rods of different diameters, improving the versatility and adaptability of the device. It is suitable for power line maintenance scenarios that require operation of spacer rods of various specifications, ensuring extensive and efficient operation.

[0041] In power line maintenance, this design can meet the installation and adjustment requirements of spacer bars of different specifications, improve the adaptability of the operating device, and is suitable for maintenance operations of various power lines, thereby reducing maintenance costs and improving work efficiency.

[0042] like Figure 1 As shown, in this embodiment, the threaded structure 72 is provided on the side of the clamping cylinder 71 facing the connecting base 30, and the retaining mechanism 73 is provided on the side of the clamping cylinder 71 away from the connecting base 30. This layout enables the device to switch working states more smoothly during operation, improves the stability of the device and the convenience of operation, is suitable for scenarios where the position of the spacer rod needs to be quickly adjusted during operation, and ensures the continuity and efficiency of operation.

[0043] In actual operation, this layout enables operators to control the position adjustment of the spacer rods more intuitively, improving the flexibility and efficiency of operation. It is suitable for fast-response power line maintenance scenarios and ensures the stable operation of the power line.

[0044] like Figure 1 and Figure 4 As shown, in this embodiment, the spacer bar operating device further includes an operating lever 80, which is disposed at an end of the drive worm 10 away from the connecting base 30. The provision of the operating lever 80 enables the operator to more conveniently control the rotation of the drive worm 10, thereby improving the convenience and efficiency of operation. This is suitable for scenarios where spacer bar operation needs to be performed at a higher position, ensuring the safety and reliability of operation.

[0045] During power line maintenance, the design of the operating lever 80 can meet the requirements of high-altitude operations, and operators can operate in a safe position, which reduces the risks of high-altitude operations and improves the efficiency and safety of operations.

[0046] like Figure 1 and Figure 4 As shown, in this embodiment, the driving worm 10 is provided with a connecting hole 11 and a mounting portion 12. The mounting portion 12 is in communication with the connecting hole 11. An elastic member 121 and an abutting member 122 are provided in the mounting portion 12. When the operating rod 80 is inserted into the connecting hole 11, the elastic member 121 applies an elastic force to the abutting member 122 so that the abutting member 122 abuts and cooperates with the operating rod 80. This design enables the operating rod 80 to be more stably connected to the driving worm 10, improving the stability and reliability of operation. It is suitable for scenarios where spacer rod operation is required in harsh environments, ensuring the accuracy and safety of operation.

[0047] In actual applications, the design of the connection hole 11 and the mounting portion 12 on the driving worm 10 can ensure the stable connection of the operating lever 80 in various environments, improve the accuracy and safety of the operation, and is particularly suitable for power line maintenance operations under severe weather conditions, ensuring the stable operation of the power system.

[0048] like Figures 1 to 4As shown, the spacer rod operating device of this embodiment realizes the precise operation and positioning of the spacer rod by driving the worm 10, the sleeve 20, the connecting seat 30, the turbine structure 40, the ejector rod 50, the clutch mechanism 60, the clamping cylinder 71, the threaded structure 72 and the retaining mechanism 73. The setting of the clutch mechanism 60 and the retaining mechanism 73 enables the device to effectively switch the working state during operation, thereby improving the operating efficiency and safety. In addition, through the cooperation of the magnetic member 731 and the magnetic attraction member 732, the reliable connection and separation between the clamping cylinder 71 and the sleeve 20 is achieved, the structure is simple and the operation is convenient. The setting of the bearing member 74 and the friction reduction structure 75 further improves the stability and service life of the device.

[0049] The advantage of this device is that it can effectively improve the accuracy and efficiency of spacer bar operation and reduce the labor intensity of operators. At the same time, its structural design is reasonable, the operation is simple, and it has good stability and reliability. It is suitable for the installation and adjustment of various spacer bars and has significant benefits for improving the maintenance efficiency and safety of power lines. In actual applications, this operating device can significantly reduce the time required for power line maintenance and reduce maintenance costs. At the same time, its precise operating capabilities can effectively avoid power line failures caused by improper operation, improve the operational stability of power lines, and provide a strong guarantee for the safe operation of the power industry. In addition, its innovative structural design and convenient operation can also provide operators with a more comfortable working experience, reduce occupational injuries, and improve operational safety. It is an important technological advancement in the field of power line maintenance.
