[0001] This application claims priority to Chinese Patent Application No. 202411717713.X, filed on November 27, 2024, entitled "Spacer Rod Operating Device", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This invention relates to the field of spacer assembly and disassembly technology, and more specifically, to a spacer operating device. Background Technology

[0003] Spacer bars, also known as spacers, are used in power transmission lines to support and separate adjacent conductors, preventing them from contacting or colliding. A spacer bar operating device, used to operate the spacer bar, typically includes a drive unit with a rotatable drive section and a sleeve. The drive unit drives the sleeve to rotate or move within the sleeve.

[0004] During the installation and removal of spacers, specialized tools are required. Traditional tools are simple mechanical structures that use screwdrivers and other tools in conjunction with adjustable pliers to work on the spacers. These tools are complex in structure, have poor performance, and are cumbersome to operate, easily causing damage to the spacers. Summary of the Invention

[0005] The main objective of this invention is to provide a spacer operating device to solve the problem of the difficulty in disassembling and assembling spacers in related technologies.

[0006] To achieve the above objectives, the present invention provides a spacer bar operating device, comprising: a drive worm; a sleeve, the drive worm being rotatably inserted within the sleeve; a connecting seat, the connecting seat being connected to the sleeve; a turbine structure, rotatably connected to the connecting seat, the turbine structure meshing with the drive worm; a push rod, the first end of the push rod being connected to the turbine structure, the second end of the push rod being a free end; and a clutch mechanism, disposed between the end of the drive worm and the connecting seat, the clutch mechanism having a first synchronous motion state and a first disengagement state. When the clutch mechanism is in the first synchronous motion state, the clutch mechanism drives the worm to move through the clutch mechanism. The sleeve moves synchronously; a clamping cylinder is movably mounted on the sleeve; a threaded structure is disposed between the sleeve and the clamping cylinder; a retaining mechanism is disposed between the sleeve and the clamping cylinder, the retaining mechanism having a second synchronous movement state and a second separation state. When the retaining mechanism is in the second synchronous movement state, the sleeve and the clamping cylinder are relatively stationary. When the retaining mechanism is in the second separation state, the sleeve and the clamping cylinder can rotate relative to each other. Wherein, when the clutch mechanism is in the first separation state, the retaining mechanism is in the second synchronous movement state, and when the clutch mechanism is in the first synchronous movement state, the retaining mechanism is in the second separation state.

[0007] Furthermore, the connecting seat is provided with a clearance recess, and the clutch mechanism is located between the clearance recess and the drive worm gear.

[0008] Furthermore, the clutch mechanism includes a nut and a threaded section. The threaded section is located on the side of the clearance recess facing the drive worm. When the drive worm rotates, the threaded section is screwed into the nut, and the nut can abut against the side of the clearance recess facing the nut.

[0009] Furthermore, the retaining mechanism includes a magnetic component and a magnetic suction component, one of which is disposed on the sleeve, and the other of which is disposed on the clamping cylinder.

[0010] Furthermore, the spacer bar operating device also includes a bearing component, the inner ring of which is connected to the drive worm gear, and the outer ring of which is connected to the sleeve.

[0011] Furthermore, the spacer bar operating device also includes a friction-reducing structure, which is disposed on the clamping cylinder. The friction-reducing structure includes a mounting base and a plurality of rolling balls disposed on the mounting base. The plurality of rolling balls are spaced apart on the side of the mounting base facing the connecting seat, and each rolling ball protrudes from the mounting base.

[0012] Furthermore, in the direction from the connecting seat to the clamping cylinder, the cross-sectional area of ​​the clamping cylinder gradually increases.

[0013] Furthermore, the threaded structure is located on the side of the clamping cylinder facing the connecting seat, while the retaining mechanism is located on the side of the clamping cylinder away from the connecting seat.

[0014] Furthermore, the spacer bar operating device also includes an operating lever, which is located at the end of the drive worm gear away from the connecting seat.

[0015] Furthermore, the drive worm gear is provided with a connecting hole and a mounting part. The mounting part communicates with the connecting hole. An elastic element and a stop element are provided inside the mounting part. The operating rod is inserted into the connecting hole, and the elastic element applies an elastic force to the stop element so that the stop element abuts and engages with the operating rod.

[0016] Applying the technical solution of this invention, a drive worm is rotatably inserted into a sleeve, a connecting seat is connected to the sleeve, a turbine structure is rotatably connected to the connecting seat and can mesh with the drive worm, the first end of the push rod is connected to the turbine structure, a clutch mechanism is disposed between the drive worm and the connecting seat, the clutch mechanism has a first synchronous motion state and a first disengagement state, a clamping cylinder is movably disposed on the sleeve, a threaded structure is disposed between the sleeve and the clamping cylinder, and a holding mechanism is disposed between the sleeve and the clamping cylinder, the holding mechanism has a second synchronous motion state and a second disengagement state. Specifically, when the clutch mechanism is in the first disengagement state, the holding mechanism is in the second synchronous motion state, and when the clutch mechanism is in the first synchronous motion state, the holding mechanism is in the second disengagement state. With the above arrangement, when the drive worm rotates, it can drive the turbine structure to rotate, thereby causing the push rod to swing and extend towards one side of the sleeve. When the drive worm continues to rotate, causing the clutch mechanism to switch from the first disengaged state to the first synchronous motion state, and the holding mechanism to switch from the second synchronous motion state to the second disengaged state, the clamping cylinder can move towards the push rod under the action of the threaded structure, thereby clamping the spacer bar. This operation method is relatively simple and can effectively drive the spacer bar. Therefore, the technical solution of this application effectively solves the problem of the difficulty in disassembling and assembling the spacer bar in related technologies.

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0026] As shown in Figure 1, in this embodiment, the spacer operating device is characterized by comprising: a drive worm 10, a sleeve 20, a connecting seat 30, a turbine structure 40, a push rod 50, a clutch mechanism 60, a clamping cylinder 71, a threaded structure 72, and a holding mechanism 73. The drive 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 meshes with the drive worm 10. The first end of the push rod 50 is connected to the turbine structure 40, and the second end of the push 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 disengagement state. When the clutch mechanism 60 is in the first synchronous motion state, the clutch mechanism 60 drives the worm 10 to drive the sleeve 20 to move synchronously. The clamping cylinder 71 is movably disposed on the sleeve 20. A threaded structure 72 is disposed between the sleeve 20 and the clamping cylinder 71. A 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] Using the technical solution of this embodiment, the drive 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 mesh with the drive worm 10, the first end of the push rod 50 is connected to the turbine structure 40, the clutch mechanism 60 is disposed between the drive worm 10 and the connecting seat 30, the clutch mechanism 60 has a first synchronous motion state and a first disengagement state, 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, and the holding mechanism 73 is disposed between the sleeve 20 and the clamping cylinder 71, the holding mechanism 73 has a second synchronous motion state and a second disengagement state. Specifically, when the clutch mechanism 60 is in the first disengagement 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 disengagement state. With the above configuration, when the drive worm 10 rotates, it drives the turbine structure 40 to rotate, causing the push rod 50 to swing and extend towards one side of the sleeve 20. When the drive worm 10 continues to rotate and the clutch mechanism 60 switches from the first disengagement state to the first synchronous motion state, and the holding mechanism 73 switches from the second synchronous motion state to the second disengagement state, the clamping cylinder 71 can move towards the push rod 50 under the action of the threaded structure 72, thereby clamping the spacer bar. This operation method is relatively simple and can effectively drive the spacer bar. Therefore, the technical solution of this embodiment effectively solves the problem of the difficulty in disassembling and assembling the spacer bar in related technologies.

[0028] This design enables the operating device to precisely operate the spacer bar by switching between the clutch mechanism 60 and the holding mechanism 73. It is especially suitable for power line maintenance scenarios that require frequent adjustment of the spacer bar position, thus 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 capability can effectively avoid line faults caused by improper operation and improve the operational stability of the line.

[0030] As shown in Figures 1 and 2, in this embodiment, the connecting seat 30 is provided with a clearance recess 31, and the clutch mechanism 60 is disposed between the clearance recess 31 and the drive worm gear 10. The design of the clearance recess 31 provides sufficient space for the clutch mechanism 60, enabling the clutch mechanism 60 to work more smoothly, reducing resistance during operation, and making it suitable for scenarios that require operation in confined spaces, thereby improving the adaptability and ease of operation of the device.

[0031] In power line maintenance, especially when operating between dense cables, the design of the avoidance recess 31 allows the operating device to better adapt to confined spaces, improving operational flexibility and efficiency, avoiding potential cable damage during operation, and ensuring the safe operation of power lines.

[0032] As shown in Figures 1 and 2, in this embodiment, the clutch mechanism 60 includes a nut 61 and a threaded section 62. The threaded section 62 is disposed on the side of the clearance recess 31 facing the drive worm 10. When the drive worm 10 rotates, the threaded section 62 is screwed into the nut 61, and the nut 61 can abut against the side of the clearance recess 31 facing the nut 61. Through the cooperation of the threaded section 62 and the nut 61, precise control of the clutch mechanism 60 is achieved, allowing the operator to easily switch the working state of the clutch mechanism 60 as needed. This is suitable for scenarios requiring fine-tuning and fixing of the spacer bar, improving the accuracy and efficiency of operation.

[0033] The aforementioned fine-tuning and fixing capabilities are extremely important in the installation and adjustment of power lines. They ensure the positional accuracy of spacers, prevent power line faults caused by improper spacer placement, and improve the reliability and safety of the power system.

[0034] As shown in Figures 1 and 3, in this embodiment, the retaining mechanism 73 includes a magnetic component 731 and a magnetic suction component 732. One of the magnetic component 731 and the magnetic suction component 732 is disposed on the sleeve 20, and the other of the magnetic component 731 and the magnetic suction component 732 is disposed on the clamping cylinder 71. The cooperative use of the magnetic component 731 and the magnetic suction component 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. It is suitable for power line maintenance scenarios that require frequent disassembly and assembly of spacers, greatly improving the convenience and efficiency of operation.

[0035] In practical applications, the cooperation between magnetic component 731 and magnetic suction component 732 enables rapid connection and separation, reducing the labor intensity of operators and improving work efficiency. Especially in emergency situations, it can quickly adjust the position of the spacer bar to ensure the stable operation of the power line.

[0036] As shown in Figures 1 and 3, in this embodiment, the spacer bar operating device further includes a bearing component 74. The inner ring of the bearing component 74 is connected to the drive worm gear 10, and the outer ring of the bearing component 74 is connected to the sleeve 20. The bearing component 74 reduces the friction between the drive worm gear 10 and the sleeve 20, improves the stability and service life of the device, and is suitable for scenarios requiring long-term continuous operation, ensuring the continuity and reliability of operation.

[0037] In power line maintenance, the use of bearing component 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, making it suitable for large-scale power line maintenance work and reducing equipment maintenance costs.

[0038] As shown in Figure 1, in this embodiment, the spacer bar 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 base 751 and a plurality of rolling balls 752 disposed on the mounting base 751. The plurality of rolling balls 752 are spaced apart on the side of the mounting base 751 facing the connecting seat 30, and each rolling ball 752 protrudes from the mounting base 751. The friction-reducing structure 75 further reduces the friction between the clamping cylinder 71 and the connecting seat 30, improves the smoothness of operation and the flexibility of the device, and is suitable for scenarios where the spacer bar needs to be operated at different angles and directions, ensuring the accuracy and stability of operation.

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

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

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

[0042] As shown in Figure 1, in this embodiment, the threaded structure 72 is disposed on the side of the clamping cylinder 71 facing the connecting seat 30, and the holding mechanism 73 is disposed on the side of the clamping cylinder 71 away from the connecting seat 30. This layout allows the device to switch working states more smoothly during operation, improving the stability and ease of operation of the device. It is suitable for scenarios where the position of the spacer bar needs to be quickly adjusted during operation, ensuring the continuity and efficiency of operation.

[0043] In practice, this layout allows operators to more intuitively control the position adjustment of the spacers, improving operational flexibility and efficiency. It is suitable for power line maintenance scenarios requiring rapid response and ensures the stable operation of power lines.

[0044] As shown in Figures 1 and 4, in this embodiment, the spacer operating device further includes an operating lever 80, which is located at the end of the drive worm gear 10 away from the connecting seat 30. The operating lever 80 allows the operator to more easily control the rotation of the drive worm gear 10, improving operational convenience and efficiency. It is suitable for scenarios requiring spacer operation at a higher position, ensuring operational safety and reliability.

[0045] In power line maintenance, the design of the operating lever 80 can meet the needs of high-altitude operations, allowing operators to operate from a safe position, reducing the risks of high-altitude operations, and improving operational efficiency and safety.

[0046] As shown in Figures 1 and 4, in this embodiment, the drive worm gear 10 is provided with a connecting hole 11 and a mounting part 12. The mounting part 12 communicates with the connecting hole 11, and an elastic element 121 and an abutment element 122 are provided inside the mounting part 12. The operating rod 80 is inserted into the connecting hole 11, and the elastic element 121 applies an elastic force to the abutment element 122 to make the abutment element 122 abut against the operating rod 80. This design allows the operating rod 80 to be connected to the drive worm gear 10 more stably, improving the stability and reliability of operation. It is suitable for scenarios where spacer bar operation is required in harsh environments, ensuring the accuracy and safety of operation.

[0047] In practical applications, the design of the connecting hole 11 and mounting part 12 on the drive worm gear 10 can ensure the stable connection of the operating rod 80 in various environments, improve the accuracy and safety of operation, and is particularly suitable for power line maintenance operations under harsh weather conditions, ensuring the stable operation of the power system.

[0048] As shown in Figures 1 to 4, the spacer operating device of this embodiment achieves precise operation and positioning of the spacer through the coordinated use of the driving worm gear 10, sleeve 20, connecting seat 30, turbine structure 40, push rod 50, clutch mechanism 60, clamping cylinder 71, threaded structure 72, and holding mechanism 73. The clutch mechanism 60 and holding mechanism 73 enable the device to effectively switch working states during operation, improving operational efficiency and safety. Furthermore, the cooperation of magnetic component 731 and magnetic suction component 732 achieves reliable connection and separation between clamping cylinder 71 and sleeve 20, resulting in a simple structure and convenient operation. The bearing component 74 and friction-reducing structure 75 further improve the stability and service life of the device.

[0049] The advantages of this device lie in its ability to effectively improve the precision and efficiency of spacer bar operation, reduce the labor intensity of operators, and its reasonable structural design, ease of operation, and excellent stability and reliability. It is suitable for the installation and adjustment of various spacer bars, significantly improving the efficiency and safety of power line maintenance. In practical applications, this operating device can significantly reduce the time required for power line maintenance and lower maintenance costs. Furthermore, its precise operation can effectively prevent power line faults caused by improper operation, improving the operational stability of power lines and providing strong support for the safe operation of the power industry. In addition, its innovative structural design and ease of operation provide operators with a more comfortable working experience, reducing occupational injuries and improving operational safety, representing a significant technological advancement in the field of power line maintenance.

Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this invention; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0051] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.
