Technical Field
[0001] This invention relates to the field of power work equipment technology, and more specifically, to a lightweight insulating rod for live-line work. Background Technology
[0002] Insulating rods for live-line working are commonly used tools in high-altitude operations, widely applied in power line inspection, maintenance, and line adjustment. This tool mainly consists of an insulating rod and auxiliary devices, designed to protect workers from electric shock. To adapt to different working environments, live-line working insulating rods need to be extendable and portable, allowing for flexible use in various spatial conditions.
[0003] Existing live-line working insulating rods are mostly designed with a fixed length or a limited adjustable range, typically relying on traditional mechanical structures to achieve a certain degree of flexibility to adapt to different working environments. This type of design gives the insulating rod a relatively stable structure, effectively preventing electric shock accidents.
[0004] However, existing technologies have some shortcomings. Existing live-line working insulating rods often fail to meet the high requirements for tool height adjustment in high-altitude operations, making it inconvenient to store long live-line working insulating rods. Summary of the Invention
[0005] In view of this, the present invention proposes a lightweight live-line working insulating rod, which aims to solve the problem that existing live-line working insulating rods cannot adjust the tool height during high-altitude operations.
[0006] This invention proposes a lightweight insulating rod for live-line working, comprising: a telescopic insulating rod body for performing live-line work; a clamping mechanism disposed at the telescopic end of the telescopic insulating rod body for clamping onto the workpiece to be clamped; and a locking mechanism disposed on the telescopic insulating rod body for locking the telescopic insulating rod body when it is telescopically extended to the corresponding length.
[0007] Furthermore, in the aforementioned lightweight live-line working insulating rod, the clamping mechanism includes: two opposing clamping plates, which are rotatably mounted on the telescopic end of the telescopic insulating rod body for rotating to clamp the two sides of the workpiece to be clamped, thereby clamping the workpiece; and a clamping drive assembly mounted on the telescopic insulating rod body, wherein the power output end of the clamping drive assembly is connected to the two clamping plates for driving the two clamping plates to rotate relative to each other to clamp the workpiece to be clamped.
[0008] Furthermore, in the aforementioned lightweight live-line working insulating rod, the clamping drive assembly includes: a telescopic support rod disposed inside the telescopic insulating rod body, and the telescopic support rod being connected to the telescopic portion of the telescopic insulating rod body for synchronous telescopic extension and retraction with the telescopic portion of the telescopic insulating rod body; a transmission rack disposed at the support end of the telescopic support rod, partially disposed inside the telescopic support rod and slidably connected to the telescopic support rod along the axial direction of the telescopic support rod, the transmission rack having meshing teeth on both sides; and two transmission gears respectively disposed on both sides of the transmission rack, the two transmission gears being able to... The telescopic insulating rod is rotatably mounted above the main body of the telescopic support rod. Two transmission gears are respectively engaged with the meshing teeth on both sides of the transmission rack. A winch reel is located at the connecting end of the telescopic support rod. A connecting rope is mounted on the winch reel, with its extension end passing through the interior of the telescopic support rod and extending to the support end of the telescopic support rod. The extension end of the connecting rope is connected to the transmission rack, used to pull the transmission rack to slide along the axial direction of the telescopic support rod, thereby driving the two transmission gears to rotate in opposite directions, and consequently driving the two clamping plates to rotate relative to each other, thus clamping the workpiece to be clamped.
[0009] Furthermore, in the aforementioned lightweight live-line working insulating rod, the telescopic support rod includes: a connecting rod disposed along the axial direction of the telescopic insulating rod body inside the telescopic insulating rod body; and a fixing rod disposed along the axial direction of the connecting rod inside the connecting rod in a slidable manner. The fixing rod is connected to the telescopic portion of the telescopic insulating rod body and is used to telescopically extend and retract synchronously with the telescopic portion of the telescopic insulating rod body.
[0010] Furthermore, in the aforementioned lightweight live-line working insulating rod, a clamping return spring is provided between the support end of the transmission rack placed inside the telescopic support rod and the telescopic support rod. This spring is used to elastically compress the transmission rack when it slides into the telescopic support rod, and push the transmission rack to return to the outward convex position when the winch reel is in a free state, so as to drive the two clamping plates to rotate relative to each other and release the clamping of the workpiece to be clamped.
[0011] Furthermore, the aforementioned lightweight live-line working insulating rod, wherein the telescopic insulating rod body comprises: a first insulating rod; and a second insulating rod, sleeved inside the first insulating rod, wherein the second insulating rod is connected to the first insulating rod along the axial direction of the first insulating rod in a sliding and rotatable manner, for adjusting the telescopic length and limiting the extended end.
[0012] Furthermore, in the aforementioned lightweight live-line working insulating rod, the inner wall of the first insulating rod is provided with a guide groove, and the outer wall of the second insulating rod is provided with a guide block, which is slidably disposed in the guide groove to limit and guide the sliding and rotation of the second insulating rod.
[0013] Furthermore, in the aforementioned lightweight live-line working insulating rod, the locking mechanism includes: two locking shells and two locking blocks; wherein, the two locking shells are mounted side-by-side on the outer wall of the first insulating rod along the length direction of the guide groove; the two locking blocks are respectively disposed within the two locking shells, and both locking blocks are slidably inserted into the first insulating rod radially; when the guide block slides along the guide groove, the guide block can push the front locking block in the forward direction of the guide block to retract into the locking shell, so that the guide block can slide and lock between the two locking blocks.
[0014] Furthermore, in the aforementioned lightweight live-line working insulating rod, a guide structure is provided on the opposite sidewalls of the locking ends of the two locking blocks. This structure is used to allow the guide block to retract into the locking housing under the pressure of the guide block when it slides from both sides of the two locking blocks to the locking blocks, so that the guide block can slide and lock between the two locking blocks.
[0015] Furthermore, in the aforementioned lightweight live-line working insulating rod, a locking structure is provided on the opposite sidewalls of the locking ends of the two locking blocks, which is used to abut against the side of the guide block when the guide block slides between the two locking blocks, so as to limit the guide block.
[0016] Furthermore, in the aforementioned lightweight live-line working insulating rod, a locking reset member is provided between the locking shell and the locking block inside, which is arranged along the sliding direction of the locking block. It is used to push the locking block back to extend into the first insulating rod after the guide block slides past the locking block, so as to limit the guide block.
[0017] Furthermore, in the aforementioned lightweight live-line working insulating rod, the locking housing is provided with a locking guide plate inside, which is slidably disposed in the locking housing along the radial direction of the first insulating rod. The connecting end of the locking block is connected to the locking guide plate, and the other end serves as a limiting end, capable of extending into the first insulating rod or retracting into the locking housing. The locking guide plate is used to guide the sliding of the locking block.
[0018] Furthermore, in the aforementioned lightweight live-line working insulating rod, the locking shell is provided with a linkage rod, which is slidably inserted through the locking shell. The end of the linkage rod inside the locking shell is connected to the locking block, and the end of the linkage rod outside the locking shell is provided with a pull ring, which is used to drive the locking block to slide radially along the first insulating rod under the action of external force, so that the locking block retracts into the locking shell, thereby allowing the guide block to slide out to both sides of the two locking blocks.
[0019] Furthermore, in the aforementioned lightweight live-line working insulating rod, the guide groove includes: a telescopic slide groove, a spiral rotation groove, and a positioning groove; wherein, the telescopic slide groove, the spiral rotation groove, and the positioning groove are sequentially arranged from the fixed end of the first insulating rod to the connecting end of the first insulating rod, and the telescopic slide groove and the positioning groove are connected by the spiral rotation groove. The telescopic slide groove is used to guide the telescopic movement of the second insulating rod along the axial direction of the first insulating rod, and the spiral rotation groove is used to guide the rotation of the second insulating rod relative to the first insulating rod.
[0020] The lightweight live-line working insulating rod provided by this invention features a telescopic insulating rod body that extends and retracts. When the telescopic insulating rod body reaches its designated length, a locking mechanism locks it in place, ensuring stable fixation during operation and preventing accidental retraction. This not only solves the problem of existing live-line working insulating rods being difficult to store due to the inability to adjust tool height during high-altitude operations, but also increases safety and stability during operation by locking the telescopic insulating rod body through the locking mechanism. This enhances stability during high-altitude operations, allowing operators to focus on their work and reducing potential hazards caused by tool instability. A clamping mechanism holds the workpiece for live-line working, improving the operator's efficiency in various tasks. In particular, by adjusting the clamping force and adapting the insulating mechanism's height, it better accommodates the clamping needs of different items, ensuring efficient and precise operation.

Detailed Implementation
[0022] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the disclosure to those skilled in the art. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0023] Existing live-line working insulating rods also have shortcomings in terms of stability, convenience, and operational flexibility. In addition, existing live-line working insulating rods often fail to meet the high stability requirements of high-altitude operations, and most of them are made of heavy materials, which increases the overall weight of the tool and affects the work efficiency. Furthermore, the design of the clamping mechanism is usually not very adaptable, which requires operators to frequently adjust the tool when performing different tasks, increasing the complexity of operation.
[0024] See Figure 1 The figure illustrates a preferred structure of the lightweight live-line working insulating rod provided by an embodiment of the present invention. As shown, the live-line working insulating rod includes: a telescopic insulating rod body 1, a clamping mechanism 2, and a locking mechanism 3; wherein, The telescopic insulating rod body 1 is used for live-line work. Specifically, the telescopic insulating rod body 1 is used for live-line work and can extend and retract to reduce the storage space required for the device, while also facilitating its transport to the work area. The telescopic insulating rod body 1 not only ensures the safety of the operation and prevents the risk of electric shock, but also improves the convenience of the device through its telescopic function, reducing the hassle of carrying and storing it, allowing workers to easily carry and retrieve the device.
[0025] Clamping mechanism 2 is located at the telescopic end of telescopic insulating rod body 1 (e.g., Figure 1 The top end of the telescopic insulating rod (shown in the figure) is used to clamp onto the workpiece to be clamped (not shown in the figure) to clamp the workpiece. Specifically, the clamping mechanism 2 is located at the telescopic end of the telescopic insulating rod body 1 and is used to clamp the workpiece to be clamped, thereby completing operations such as opening and closing switches, adjusting circuits, removing foreign objects, and installing or replacing equipment. The clamping mechanism 2 improves the flexibility and efficiency of the operation. Through simple operation, the operator can adjust the clamping force and adapt to the usage height of the telescopic insulating rod body 1, thereby improving the portability of the device.
[0026] A locking mechanism 3 is installed on the telescopic insulating rod body 1 to lock the telescopic insulating rod body 1 when it is extended to the corresponding length. Specifically, it is installed on the outside of the telescopic insulating rod body 1 and is used to lock the telescopic insulating rod body 1 during its extension process, thereby adjusting the usage state of the telescopic insulating rod body 1. The locking mechanism 3 ensures that the telescopic insulating rod body 1 will not slip or retract during high-altitude operations, thus improving the safety and stability of operation and allowing operators to concentrate on operation in complex working environments without worrying about tool instability. In this embodiment, multiple locking mechanisms 3 can be used to lock different extension lengths.
[0027] See also Figures 1 to 4 The telescopic insulating rod body 1 includes: a first insulating rod 11 and a second insulating rod 12; wherein, the second insulating rod 12 is sleeved inside the first insulating rod 11, and the second insulating rod 12 is axially aligned with the first insulating rod 11 (e.g., ...). Figure 1 The vertical direction shown is connected to the first insulating rod 11 in a sliding and rotating manner for adjusting the telescopic length and limiting the extended end.
[0028] Specifically, a second insulating rod 12 is slidably connected inside the first insulating rod 11. The second insulating rod 12 and the first insulating rod 11 are coaxially arranged and can slide and rotate relative to each other. The relative sliding between them allows for extension and retraction, while the relative rotation prevents them from retracting on their own, thus achieving a limiting effect. Both the first insulating rod 11 and the second insulating rod 12 are hollow insulating rods. In this example, a bottom support plate 112 can be provided at the bottom end of the first insulating rod 11 to support the internal second insulating rod 12, preventing it from shifting downwards from the bottom of the first insulating rod 11 and detaching from it. The first insulating rod 11 and the second insulating rod 12 can be made of aramid resin composite material. Aramid resin composite material has excellent tensile and flexural strength, can withstand large external forces without deformation or breakage, maintains good mechanical properties and structural stability even at high temperatures, and also has good electrical insulation properties. Using aramid resin composite material reduces the overall weight of the device, making operation easier for workers and improving work efficiency.
[0029] In this embodiment, a guide groove 111 is provided on the inner wall of the first insulating rod 11, and a guide block 121 is provided on the outer wall of the second insulating rod 12. The guide block 121 is slidably disposed within the guide groove 111 to limit and guide the sliding and rotation of the second insulating rod 12. The guide block 121 is adapted to the guide groove 111 to limit and guide the sliding and rotation of the second insulating rod 12. The limiting effect of the guide block 121 allows the second insulating rod 12 to slide vertically and rotate within the first insulating rod 11, preventing the second insulating rod 12 and the first insulating rod 11 from detaching radially. In this embodiment, both the guide groove 111 and the guide block 121 can be two, to improve the stability of the relative movement of the first insulating rod 11 and the second insulating rod 12. In this embodiment, the locking mechanism 3 can be set at the position corresponding to the guide groove 111. When the guide block 121 slides along the guide groove 111 to the corresponding position, the locking mechanism 3 can lock the guide block 121, thereby locking the second insulating rod 12 at the corresponding height.
[0030] See also Figure 6The top of the second insulating rod 12 has a top support plate 122 for supporting the top clamping mechanism 2.
[0031] See also Figure 3 and Figure 4 The guide groove 111 includes: a telescopic slide groove 1111, a spiral rotating groove 1112, and a positioning groove 1113; wherein, the telescopic slide groove 1111, the spiral rotating groove 1112, and the positioning groove 1113 originate from the fixed end of the first insulating rod 11 (e.g., Figure 3 The connection end from the bottom end shown to the first insulating rod 11 (as shown) Figure 3 The top of the rod is arranged in sequence, and the telescopic groove 1111 and the positioning groove 1113 are connected by a spiral groove 1112. The telescopic groove 1111 is used to guide the telescopic movement of the second insulating rod 12 along the axial direction of the first insulating rod 11, and the spiral groove 1112 is used to guide the rotation of the second insulating rod 12 relative to the first insulating rod 11.
[0032] Specifically, the telescopic slide 1111 is a straight slide 11 arranged along the axial direction of the first insulating rod 11, and the positioning groove 1113 is a groove structure adapted to the guide block 121. Furthermore, there is a gap between the positioning groove 1113 and the telescopic slide 1111, and the two are connected by a spiral groove 1112. The telescopic slide 1111, the spiral groove 1112, and the positioning groove 1113 all provide space for the guide block 121 to move. Through the cooperation of the telescopic slide 1111 and the spiral groove 1112, the second insulating rod 12 can be moved vertically and then... Rotation; In this embodiment, both the spiral groove 1112 and the positioning groove 1113 are located at the connecting end of the first insulating rod 11, so that after the second insulating rod 12 slides along the telescopic groove 1111 with the guide block 121 to the connecting end of the first insulating rod 11, in order to prevent the second insulating rod 12 from retracting or sliding downward under the action of gravity, the guide block 121 can slide along the spiral groove 1112, thereby realizing the relative rotation between the first insulating rod 11 and the second insulating rod 12, so that the guide block 121 can slide to the positioning groove 1113. In this embodiment, the positioning groove 1113 can be an open groove at both the top and bottom. The bottom opening communicates with the spiral groove 1112, allowing the guide block 121 to slide from the spiral groove 1112 into the positioning groove 1113. The top opening facilitates the guide block 121 to continue moving upward, thereby separating the first insulating rod 11 and the second insulating rod 12, and thus enabling disassembly of the two. This allows for removal, storage, or replacement, improving the storage options of the device, as it can be stored retracted or disassembled. Of course, during reassembly, the guide block 121 can also rotate downward from the positioning groove 1113 and slide into the telescopic slide groove 1111. Transition portions are provided between the telescopic slide groove 1111 and the spiral groove 1112, and between the spiral groove 1112 and the positioning groove 1113, to allow the guide block 121 to slide smoothly.
[0033] In this embodiment, different environments are encountered during the use of the lightweight live-line working insulating rod, so it is necessary to work in different environments, which can easily lead to damage. In order to avoid insulation failure, the second insulating rod 12 and the first insulating rod 11 can be maintained by removing them. During the maintenance process, another corresponding rod can be used for replacement. This operation can also be changed according to the size of the clamping required, so that it can clamp objects of different sizes and perform operations.
[0034] See also Figure 3 and Figure 4 The locking mechanism 3 is located at the position corresponding to the spiral groove 1112. When the guide block 121 slides along the spiral groove 1112, i.e., when the second insulating rod 12 rotates relative to it, the locking mechanism 3 locks the guide block 121, thereby locking the second insulating rod 12 at the corresponding height. In particular, compared to setting the telescopic slide 1111, the vertical gravity borne by the locking mechanism 3 at the spiral groove 1112 is greatly reduced, ensuring the stability of the locking. When disassembling the second insulating rod 12, the locking mechanism 3 can be in a non-working state, allowing the guide block 121 to slide from the locking mechanism 3 into the positioning groove 1113 and out from the top opening, thus achieving disassembly. Reassembly is performed in accordance with the disassembly method, which will not be described further in this embodiment. Of course, in other embodiments, the locking mechanism 3 can also be provided at the telescopic slide 1111, or the locking mechanism 3 can be provided at different height positions of the telescopic slide 1111, and the locking mechanism 3 can also be provided at the spiral groove 1112. The locking of the second insulating rod 12 at different extension lengths can be achieved by different locking mechanisms.
[0035] See also Figure 1 , Figure 5 , Figure 7 and Figure 8 The clamping mechanism 2 includes: two clamping plates 21 and a clamping drive assembly 22; wherein, the two clamping plates 21 are arranged opposite to each other, and the two clamping plates 21 are mounted on the telescopic end of the telescopic insulating rod body 1 in a manner that allows them to rotate relative to each other (e.g., Figure 7 The top of the rod (as shown) is used to rotate to clamp the two sides of the workpiece to be clamped, thereby clamping the workpiece to be clamped; the clamping drive assembly 22 is set on the telescopic insulating rod body 1, and the power output end of the clamping drive assembly 22 is connected to the two clamping plates 21, which is used to drive the two clamping plates 21 to rotate relative to each other, so as to clamp the workpiece to be clamped.
[0036] Specifically, the two clamping plates 21 are arranged at the telescopic end of the second insulating rod 12 in a manner that allows them to rotate relative to each other (e.g., Figure 1(As shown at the top), that is, the two clamps 21 can rotate synchronously and relative to each other in opposite directions. Figure 7 The state shown is the loosened state of the two clamping plates 21. In this state, both clamping plates 21 are horizontally arranged. Each clamping plate 21 is connected to the power output end of the clamping drive assembly 22 via a swing arm 23. Driven by the clamping drive assembly 22, the two swing arms 23 can rotate synchronously and in opposite directions, thereby causing the two clamping plates 21 to rotate accordingly. For example, when rotating from the loosened state to the clamped state, driven by the clamping drive assembly 22, the left swing arm 23 rotates counterclockwise, while the right swing arm 23 rotates clockwise simultaneously. The two swing arms rotate in opposite directions and have equal angular velocities, thus ensuring that the clamping surfaces of the two clamping plates 21 (such as...) are aligned. Figure 7 The top walls (shown) gradually decrease in angle from 180°, meaning they move closer to each other to clamp the workpiece on both sides, allowing for pulling and other operations. If there is no workpiece to be clamped (i.e., when the clamp is empty), the clamping surfaces of the two clamping plates 21 can contact each other during clamping. In this embodiment, to prevent damage to the workpiece during clamping, preferably, each clamping surface of the two clamping plates 21 is provided with a rubber pad 24 for elastic cushioning during clamping. The rubber pads 24 allow the clamping plates 21 to adapt to objects of different shapes, thus increasing clamping stability and preventing damage to the workpiece.
[0037] See also Figure 5 , Figure 7 and Figure 8 The clamping drive assembly 22 includes: a telescopic support rod 221, a transmission rack 222, two transmission gears 223, and a winch reel 224; wherein, the telescopic support rod 221 is disposed inside the telescopic insulating rod body 1, and the telescopic support rod 221 is connected to the telescopic part of the telescopic insulating rod body 1, i.e., the second insulating rod 12, for synchronous telescopic extension and retraction with the telescopic part of the telescopic insulating rod body 1, i.e., the second insulating rod 12; the transmission rack 222 is disposed at the support end of the telescopic support rod 221 (e.g., Figure 7 As shown at the top), the transmission rack 222 is partially disposed inside the telescopic support rod 221 and is slidably connected to the telescopic support rod 221 along the axial direction of the telescopic support rod 221. Both sides of the transmission rack 222 are provided with meshing teeth. Two transmission gears 223 are respectively disposed on both sides of the transmission rack 222. The two transmission gears 223 are rotatably disposed above the telescopic insulating rod body 1, and the two transmission gears 223 are respectively meshed with the meshing teeth on both sides of the transmission rack 222. The winch reel 224 is disposed at the connecting end of the telescopic support rod 221 (e.g., at the top). Figure 5(As shown at the bottom end), a connecting rope 225 is provided on the winch reel 224, that is, the connecting end of the connecting rope 225 is connected to the winch reel 224, and the tension end of the connecting rope 225 (such as...) Figure 7 The top end of the cable (as shown) passes through the interior of the telescopic support rod 221 and extends to the support end of the telescopic support rod 221. The tension end of the connecting rope 225 is connected to the transmission rack 222 and is used to pull the transmission rack 222 to slide along the axial direction of the telescopic support rod 221, so as to drive the two transmission gears 223 to rotate in opposite directions, thereby driving the two clamping plates 21 to rotate relative to each other, so as to clamp the workpiece to be clamped.
[0038] Specifically, the telescopic support rod 221 can be a telescopic rod adapted to the telescopic insulating rod body 1. The telescopic support rod 221 is located inside the second insulating rod 12 and is arranged coaxially with the second insulating rod 12. The telescopic support rod 221 can telescopically extend and retract synchronously with the telescopic insulating rod body 1. That is, when the second insulating rod 12 extends and retracts, it can drive the support end, i.e. the telescopic end, of the telescopic support rod 221 to telescopically extend and retract synchronously. The telescopic support rod 221 is used to support the top clamping plate 21, the swing arm 23, the clamping drive assembly 22 and other structures. The telescopic support rod 221 has a rope-passing hole inside, so that the connecting rope 225 can pass through the rope-passing hole and connect to the transmission rack 222 located at the support end of the telescopic support rod 221 and the winch reel 224 located at the connecting end of the telescopic support rod 221. The rotation of the winch reel 224 causes the connecting rope 225 to be wound up, thereby pulling the transmission rack 222 to reciprocate linearly along the axial direction of the telescopic support rod 221, thus driving the two transmission gears 223 to rotate synchronously in opposite directions. In this embodiment, the connecting end of the swing arm 23 (e.g., Figure 7 The right end of the left swing arm 23 shown can be coaxially arranged and connected to the transmission gear 223 so as to rotate synchronously and in the same direction as the transmission gear 223. The support end of the swing arm 23 (such as...) Figure 7 The left end of the left swing arm 23 shown is connected to the clamping plate 21, which can drive the clamping plate 21 to rotate and adjust its position with the transmission gear 223.
[0039] See also Figure 5 The connecting end of the telescopic support rod 221 may be provided with a wire-feeding shell 226, and the winch wire-feeding reel 224 is rotatably inserted through the wire-feeding shell 226. Specifically, the connecting end of the telescopic support rod 221 is rotatably inserted through the bottom support plate 112 so that the telescopic support rod 221 can rotate with the second insulating rod 12 relative to the first insulating rod 11, thereby avoiding problems such as tangling of the connecting rope 225.
[0040] In this embodiment, to ensure the stability of the clamping of the clamping plate 21, preferably, the winch wire release wheel 224 is connected to a winch locking member (not shown in the figure), which is used to lock the winch wire release wheel 224 on the wire release shell 226 when the two clamping plates 21 are clamped on both sides of the workpiece to be clamped, so as to prevent the winch wire release wheel 224 from rotating on its own, thereby preventing the automatic release of the connecting rope.
[0041] See also Figure 5 The winch reel 224 is equipped with a handle 227, and the handle 227 may have anti-slip grooves. The combination of the handle 227 and the anti-slip grooves allows the user to rotate the winch reel 224 more conveniently and comfortably, thereby facilitating the winding of the connecting rope 225. Specifically, handles 227 can be provided at both ends of the winch reel 224. The handle 227 can be a disc structure, coaxially arranged with the winch reel 224. The outer wall of the handle 227 has several spaced anti-slip grooves arranged circumferentially.
[0042] See also Figure 8 To facilitate the reset of the clamping plate 21 to the released state, preferably, the transmission rack 222 is placed at the support end inside the telescopic support rod 221 (e.g., Figure 8 A clamping return spring 228 is provided between the top end shown and the telescopic support rod 221. It is used to elastically compress the transmission rack 222 when it slides into the telescopic support rod 221, and push the transmission rack 222 to return to the outward convex position when the winch unwinding wheel 224 is in a free state, so as to drive the two clamping plates 21 to rotate relative to each other and release the clamping of the workpiece to be clamped.
[0043] Specifically, the clamping return spring 228 is sleeved on the outer periphery of the connecting rope 225, and its two ends can be connected to the end of the transmission rack 222 placed inside the telescopic support rod 221 and the telescopic support rod 221, respectively, so as to apply a return force to the transmission rack 222, so that the transmission rack 222 can slide upward under the action of the return force, thereby driving the two transmission gears 223 to rotate synchronously in opposite directions, and driving the swing rod 23 and the clamping plate 21 to rotate, so that the clamping plate 21 returns to the horizontal loosened state.
[0044] See also Figure 8 To ensure the stability of the clamping return spring 228, preferably, a limiting plate 229 is provided at the bottom of the support end of the transmission rack 222 placed inside the telescopic support rod 221. The limiting plate 229 is slidably disposed inside the telescopic support rod 221 to synchronously adjust the position of the transmission rack 222 and compress the clamping return spring 228.
[0045] See also Figures 2 to 5 , Figure 7 and Figure 8The telescopic structure of the telescopic support rod 221 can refer to the structure of the telescopic insulating rod body 1, and may include: a connecting rod 2211 and a fixing rod 2212; wherein, the fixing rod 2212 is sleeved inside the connecting rod 2211, and the fixing rod 2212 is along the axial direction of the connecting rod 2211 (e.g., Figure 2 (In the vertical direction shown) it is slidably connected to the connecting rod 2211 for adjusting the telescopic length.
[0046] Specifically, the fixed end of the connecting rod 2211 (such as...) Figure 2 The bottom end (shown) can be supported on the bottom support plate 112, and the connecting rod 2211 is slidably inserted through the bottom support plate 112. The fixed end located on the lower side of the bottom support plate 112 can be fixedly installed with a wire release shell 226. The fixed rod 2212 is slidably disposed inside the connecting rod 2211. To prevent the two from separating, preferably, the inner wall of the connecting rod 2211 is provided with a limiting groove 22111, and the outer wall of the fixed rod 2212 is provided with a limiting block 22121 that matches the limiting groove 22111. The limiting block 22121 is slidably disposed in the limiting groove 22111 to ensure the stability of the sliding of the connecting rod 2211 and the fixed rod 2212. There are four limiting grooves 22111 and four limiting blocks 22121, but other numbers, such as one or more, can also be used. In this embodiment, no such number is specified. In this embodiment, the top end of the limiting groove 22111 is an open end, so that the connecting rod 2211 and the fixing rod 2212 can be axially separated from each other through the top opening, that is, disassembled along with the first insulating rod 11 and the second insulating rod 12, so that the connecting rod 2211 and the first insulating rod 11 are combined into a whole, and the fixing rod 2212 and the second insulating rod 12 are combined into a whole. In this embodiment, as... Figure 6 As shown, the top support plate 122 of the second insulating rod 12 is provided with mounting holes 1221 and mounting grooves 1222 that match the limiting block 22121. The connecting rod 2211 and the circumferential limiting block 22121 can be fixedly installed in the mounting holes 1221 and mounting grooves 1222, so that the second insulating rod 12 can drive the fixed rod 2212 to extend and retract synchronously from the connecting rod 2211 while the second insulating rod 12 extends and retracts. The fixed rod 2212 is provided with a rope hole inside, and the connecting rope 225 passes through the inside of the connecting rod 2211 and the rope hole.
[0047] In this embodiment, the limiting groove 22111 and the limiting block 22121 can not only limit and guide, but also allow the connecting rod 2211 and the fixing rod 2212 to rotate simultaneously, thereby avoiding problems such as wire entanglement in the device.
[0048] In this embodiment, while the fixed rod 2212 extends and retracts, the winch reel 224 simultaneously winds up the wire. After the fixed rod 2212 and the second insulating rod 12 extend into place and are locked by the locking mechanism 3, the winch reel 224 winds up the connecting rope 225, which pulls the transmission rack 222 downward, thereby driving the left transmission gear 223 to rotate clockwise and the right transmission gear 223 to rotate counterclockwise. This causes the left swing arm 23 to rotate clockwise with the left transmission gear 223 and the right swing arm 23 to rotate counterclockwise with the right transmission gear 223, so that the two clamping plates 21 move closer to each other until the two clamping plates 21 are clamped on both sides of the workpiece to be clamped, thus achieving the clamping of the workpiece.
[0049] See also Figure 8 The interior of the fixing rod 2212 is near the telescopic end (e.g. Figure 8 A guide hole 22122 is provided at the top position (as shown), which is adapted to the outer contour of the limiting plate 229. The limiting plate 229 is slidably disposed in the guide hole 22122 along the axial direction of the fixing rod 2212 to guide the sliding of the transmission rack 222 and limit the sliding of the transmission rack 222 at both ends, preventing the transmission rack 222 from completely sliding into the fixing rod 2212 or completely sliding out of the fixing rod 2212. The clamping return spring 228 is arranged on the bottom wall of the limiting plate 229 and the guide hole 22122.
[0050] See also Figure 4 The locking mechanism 3 may include two locking shells 31 and two locking blocks 32. The two locking shells 31 are mounted side by side on the outer wall of the first insulating rod 11 along the length of the guide groove 111. The two locking blocks 32 are respectively disposed in the two locking shells 31. The two locking blocks 32 are slidably disposed in the first insulating rod 11 along the radial direction of the first insulating rod 11. When the guide block 121 slides along the guide groove 111, the guide block 121 can push the front locking block 32 in the forward direction of the guide block 121 to retract into the locking shell 31, so that the guide block 121 can slide and lock between the two locking blocks 32.
[0051] Specifically, the first insulating rod 11 has two spaced-apart through holes corresponding to the spiral groove 1112. Two locking shells 31 are respectively disposed at the two through holes, and the spacing between the through holes can be determined according to the guide block 121. The locking shell 31 is hollow inside and communicates with the spiral groove 1112 through the through holes. The locking block 32 corresponds one-to-one with the locking shell 31. The corresponding locking block 32 is slidably inserted through the locking shell 31 and the through hole, so that when the guide block 121 slides past the locking block 32, it retracts into the locking shell 31 and the through hole, and when the guide block 121 is limited and locked, it can extend into the spiral groove 1112. In this embodiment, when the guide block 121 is locked, the guide block 121 slides from the telescopic groove 1111 into the spiral groove 1112 and slides along the spiral groove 1112 toward the locking block 32. A pressing force can be applied to the locking block 32 on the front side, that is, the first locking block 32 that is first contacted on the sliding path. The locking block 32 can retract, so that the guide block 121 continues to slide along the spiral groove 1112 through the position of the locking block 32, so that it slides between the two locking blocks 32, releasing the pressing on the locking block 32, so that the locking block 32 can extend into the spiral groove 1112 to limit the sliding of the guide block 121. The other locking block 32 is always in the extended state to limit and lock the continued sliding of the guide block 121, so that the guide block 121 is locked between the two locking blocks 32. Of course, when releasing the lock on the guide block 121, the locking block 32 in the forward direction of the guide block 121 can be controlled to retract. That is, when the guide block 121 slides into the telescopic groove 1111, the locking block 32 can be controlled to retract. Figure 4 The upper locking block 32 retracts, allowing the guide block 121 to pass through the upper locking block 32 and slide into the telescopic groove 1111 to engage and lock, thus retracting the second insulating rod 12. Conversely, when the guide block 121 slides into the positioning groove 1113, the control... Figure 4 The lower locking block 32 shown retracts, allowing the guide block 121 to pass through the lower locking block 32 to slide into the positioning groove 1113, and to be removed from the positioning groove 1113.
[0052] See also Figure 4A locking reset member 33 is provided between the locking housing 31 and the locking block 32 inside. Arranged along the sliding direction of the locking block 32, it pushes the locking block 32 back into the spiral groove 1112 after the guide block 121 slides past it, thus limiting the guide block 121. Specifically, the locking reset member 33 is a spring structure. It can elastically compress and apply a reset force to the locking block 32 when the locking block 32 retracts into the locking housing 31, i.e., when the guide block 121 presses the locking block 32 back into the locking housing 31. This allows the locking block 32 to be in a free state after the guide block 121 passes its position, allowing it to extend into the spiral groove 1112 under the reset force of the locking reset member 33, thereby limiting the sliding of the guide block 121.
[0053] See also Figure 4 To improve the telescopic stability of the locking block 32, preferably, the locking housing 31 is provided with a locking guide plate 34 inside, which is slidably disposed inside the locking housing 31 along the radial direction of the first insulating rod 11. The connecting end of the locking block 32 (e.g. Figure 4 The left end shown is connected to the locking guide plate 34, and the other end (as shown) is connected to the locking guide plate 34. Figure 4 The right end (shown as a limiting end) can extend into the first insulating rod 11 or retract into the locking housing 31. The locking guide plate 34 is used to guide the sliding of the locking block 32. Specifically, the locking guide plate 34 matches the inner cavity of the locking housing 31 and can slide within the locking housing 31 to guide the sliding of the locking block 32 when it retracts or extends, so that the locking block 32 only moves in parallel. This avoids the problem of deformation and damage to the locking reset member 33 due to the tilting and squeezing of the locking block 32, and improves the service life of the locking reset member 33. In this embodiment, the locking reset member 33 is sandwiched between the locking guide plate 34 and the locking housing 31 to apply a reset force to the locking guide plate 34 so that the locking guide plate 34 can drive the locking block 32 to reset and extend.
[0054] See also Figure 4 To facilitate the unlocking of the locking block 32, preferably, the locking housing 31 is provided with a linkage rod 35, which is slidably inserted through the locking housing 31. The linkage rod 35 is located at the end inside the locking housing 31 (e.g., Figure 4 The right end shown is connected to the locking block 32, and the linkage rod 35 is located at the end outside the locking housing 31 (as shown). Figure 4A pull ring 36 is provided on the left end (shown) to drive the locking block 32 to slide radially along the first insulating rod 11 under the action of external force, so that the locking block 32 retracts into the locking shell 31, thereby allowing the guide block 121 to slide out to both sides of the two locking blocks 32. Specifically, the end of the linkage rod 35 placed in the locking shell 31 can be connected to the locking guide plate 34, and the locking reset member 33 can be sleeved on the outer periphery of the linkage rod 35. By pulling the linkage rod 35 to the left through the pull ring 36, the locking guide plate 34 and the locking block 32 will slide to the left, so that the locking block 32 retracts into the locking shell 31 or into the through hole, preventing the locking block 32 from locking the guide block 121, thereby unlocking, and also allowing the guide block 121 to slide smoothly past the locking block 32.
[0055] In this embodiment, in order for the locking blocks 32 to retract under the squeezing action of the guide blocks 121 placed outside the two locking blocks 32, preferably, the locking ends of the two locking blocks 32 (such as...) Figure 8 The opposite sidewall of the right end shown (as shown) Figure 4 The upper sidewall of the upper locking block 32 and the lower sidewall of the lower locking block 32 are provided with guide structures 321. These guide structures are designed to retract into the locking housing 31 under the pressure of the guide blocks 121 when the guide blocks 121 slides from both sides of the two locking blocks 32 to the locking blocks 32, so that the guide blocks 121 can slide and lock between the two locking blocks 32. Specifically, the guide structure 321 is arc-shaped. The arc shape allows the locking blocks 32 to be pressed against it when they come into contact with the arc shape, thus making it easy to pass over.
[0056] See also Figure 4 The opposite sidewalls of the locking ends of the two locking blocks 32 are as follows: Figure 4The lower side wall of the upper locking block 32 and the upper side wall of the lower locking block 32 shown are provided with locking structures 322, which are used to abut against the side of the guide block 121 when the guide block 121 slides between the two locking blocks 32, so as to limit the guide block 121. Specifically, the locking structure 322 can be a planar structure. The planar surface can restrict the locking block 32, thereby preventing it from moving and improving the locking efficiency. In other words, the second insulating rod 12 can be moved vertically and rotated by the cooperation of the telescopic slide 1111 and the spiral rotating groove 1112. After rotation, the guide block 121 can squeeze the guide structure 321 to retract the front locking block 32, so that the guide block 121 can slide through the locking block 32 and be placed between the two locking blocks 32. The locking reset member 33 causes the retracted locking block 32 to retract, so that the guide block 121 is locked between the locking structure 322 of the two locking blocks 32, thereby locking the second insulating rod 12. After the operation is completed, the pull ring 36 on the front side of the forward direction can be pulled to compress the locking reset member 33 of the corresponding locking block 32. The guide block 121 slides through the locking block 32, that is, slides out from between the two locking blocks 32, and the second insulating rod 12 can be retracted. It can slide in the opposite direction to the positioning groove 1113 for removal and replacement.
[0057] The working principle of this insulating rod: In use, by pulling the second insulating rod 12, it slides outward along the axial direction of the first insulating rod 11 until it can no longer move axially. Then, the second insulating rod 12 is rotated. When the second insulating rod 12 rotates, the guide block 121 contacts the guide surface of the locking block 32 on the front side of the forward direction, thereby pressing it. At the same time as pressing, the locking reset member 33 is compressed by the pressure of the locking block 32. When the second insulating rod 12 passes, the locking block 32 is ejected by the elastic force of the locking reset member 33. At this time, the guide block 121 is located between the locking structures of the two locking blocks 32, thereby limiting and locking the guide block 121. At this time, when using the first insulating rod 11 and the second insulating rod 12, the second insulating rod... The guide block 121 can be released by pulling the pull ring 36, which can retract the second insulating rod 12 or remove and store or replace the second insulating rod 12 and the first insulating rod 11. At the same time as pulling the second insulating rod 12, the fixed rod 2212 can be pulled out from the inside of the connecting rod 2211, so that the height of the clamping mechanism 2 can be adjusted at the same time. When needed, the connecting rope 225 is wound up by rotating the winch unwinding wheel 224. During the winding process, the transmission rack 222 moves downward and compresses the clamping return spring 228. At the same time as the movement, the transmission gear 223 and the swing rod 23 rotate, so that the two clamping plates 21 move closer to each other to clamp the workpiece to be clamped.
[0058] In summary, the lightweight live-line working insulating rod provided in this embodiment extends and retracts via a telescopic insulating rod body. When the telescopic insulating rod body extends to the corresponding length, a locking mechanism locks the extension and retraction of the telescopic insulating rod body, ensuring that the telescopic insulating rod body is stably fixed during operation and avoiding the risk of accidental retraction. This not only solves the problem of existing live-line working insulating rods being difficult to store due to the inability to adjust the tool height during high-altitude operations, but also increases the safety and stability of the operation by locking the telescopic insulating rod body through the locking mechanism. This improves the stability during high-altitude operations, ensuring that operators can focus on the operation and reducing potential dangers caused by tool instability. The clamping mechanism clamps the workpiece to be clamped for live-line work, improving the operational efficiency of operators when performing various tasks. In particular, by adjusting the clamping force and adapting the height of the insulating mechanism, it can better adapt to the clamping requirements of different items, ensuring efficient and accurate completion of the operation.
