Description

Technical Field

[0001] This invention relates to the construction of overhead power transmission lines, and more particularly to an automatic traction and laying device for overhead lines. Background Technology

[0002] Currently, during the replacement of conductors and ground wires for overhead power lines, the traction and laying of the wires mostly involves manual labor, using a trolley to move from one tower to the other to lay the wires. This method is also commonly used when laying overhead wires for crossings. This method carries a high risk, especially when the conductors and ground wires are severely corroded. To avoid these risks, drones have been used for wire laying. However, using drones for traction and laying requires highly skilled operators with specialized drone training, placing a high demand on general construction workers. There is a need for a simpler operating device that allows general construction workers to perform unmanned traction and laying of wires without extensive specialized training. Summary of the Invention

[0003] The purpose of this invention is to provide an automatic traction and cable laying device for overhead lines in an attempt to solve the problems of dangerous manual cable laying operations and the high professional requirements and inconvenience of unmanned aerial vehicle cable laying.

[0004] To solve the above problems or achieve the above objectives, the present invention provides an automatic traction and cable laying device for overhead lines, comprising a device body, a rope clamping part, and a traveling part. The rope clamping part is disposed on the device body and is used to clamp the rope. The traveling part is disposed above the device body and is movably connected to the tower ground wire. The traveling part is equipped with a drive assembly that drives it to move forward or backward on the ground wire, allowing the device body to move suspended on the ground wire. The traveling part includes symmetrical supports located on both sides of the device body. One support is provided with a suspension wheel for suspending on the ground wire. The suspension wheel is equipped with the drive assembly. The other support is provided with a coupling corresponding to the rotation axis of the suspension wheel. The coupling has an elastically retractable docking part for engaging with the rotation axis of the suspension wheel. When the docking part is retracted, a gap that allows the ground wire to pass through appears between the docking part and the rotation axis of the suspension wheel.

[0005] In use, the worker connects the suspension wheel of the traveling part to the existing ground wire of the overhead line, i.e., retracts the aforementioned docking part. A gap appears between the docking part and the rotating shaft of the suspension wheel, allowing the ground wire to pass through. The suspension wheel of this device is then suspended on the ground wire. In this way, utilizing the existing ground wire, the device can directly use the baseline as a track. The guide rope is clamped on the aforementioned guide rope clamping part. This traction and laying device brings the guide rope to the pole on the other side, where workers on that pole receive it to complete the traction and laying of the line. This device can complete the laying of the guide rope under manual control, thereby reducing manual line handling. This device reduces operational risks by simplifying the three-dimensional (aerial control) control required by drones to one-dimensional control (using the existing ground wire as a guide rail; workers only need to start the device). This greatly simplifies the operation of unmanned rope laying, making it easy for general workers to operate. Furthermore, the device is supported by the existing ground wire and does not require a complex and powerful drive motor, allowing for a compact design that is very convenient for workers to carry. Operation requires only three steps: suspend the device on the ground wire, clamp the rope, and start the device to complete the operation.

[0006] In some feasible embodiments, the support includes a front support rod and a rear support rod; the front support rod is a folded rod structure, with its bent portion rotatably connected to the main body of the device, and both ends located above the main body of the device; the rear support rod is a straight rod structure, with one end rotatably connected to the main body of the device; the suspension wheel includes a front pulley, a middle pulley, and a rear pulley; the front pulley and the middle pulley are respectively located at the end of the front support rod away from the rear support rod and the end closer to the rear support rod, with the front pulley located in front of the main body of the device; the rear pulley is located at the other end of the rear support rod.

[0007] In elevated power transmission lines, the installed ground conductor is not straight. Due to its center of gravity, it sags between towers. For this automatic traction and cable-laying device that uses this ground conductor as a track, if a single-wheel travel is used, the suspension device below the wheel will cause unstable swaying during travel. Especially after the downward travel is completed, the speed is unstable and the forward movement is sluggish in the middle of the ground conductor and during the upward travel. Combined with airflow, the clamped guide rope swings strongly, and this situation becomes more pronounced as the travel distance increases. Therefore, considering the characteristic of the ground conductor, which exhibits a certain degree of sag as a "track," how can a small and lightweight (the weight of this device should only be enough for the suspension wheel to have grip and friction with the ground conductor) automatic traction and cable-laying device be designed? The lead-out device, capable of moving stably and evenly along the ground line, is a crucial factor in ensuring efficiency and stability during lead-out and line-laying operations. To address this, this automatic traction lead-out device employs a two-support design: a forked, folded rod for the front support and a single straight rod for the rear support, utilizing three sets of pulleys. The first two pulleys are mounted on the front support, with the middle pulley providing power. The front support uses a two-wheel structure connected by the same support, ensuring that the upward support force of the front pulley, through leverage, keeps the middle pulley under downward pressure on the drooping "track." Combined with the device's own weight, this provides a more reliable grip on the ground line and allows for self-adjustment based on the degree of ground line sag. This enables the middle power pulley to more stably drive the main body of the device.

[0008] In some feasible embodiments, the rear support rod is rotatably connected to the main body of the device via a connecting shaft, and a torsional elastic element is fitted onto the connecting shaft. One end of the torsional elastic element is connected to the main body of the device, and the other end is connected to the rear support rod. This rear support rod is a single rod, and under normal conditions, the rear pulley of the rear support rod is aligned with the front pulley and the middle pulley.

[0009] In some feasible embodiments, the front support rod is rotatably connected to the main body of the device via a connecting shaft, and a torsion elastic element is fitted on the connecting shaft. One end of the torsion elastic element is connected to the main body of the device, and the other end is connected to the rear support rod. When the torsion elastic element is relaxed, the front pulley is located in front of the main body of the device.

[0010] In some feasible embodiments, a bracket with a coupling is connected to the lower edge of the device body via a spring hinge, so that the bracket can be rotated around the spring hinge, and when returned to its original position, the coupling corresponds to the shaft of the suspension wheel.

[0011] In some feasible embodiments, the rope clamping part is located on the lower side of the device body and corresponds vertically to the front support rod. The front pulley and rear pulley are driven pulleys; the middle pulley is the driving pulley; a first motor is provided at one end of the front support rod near the rear support rod; the first motor is connected to the middle pulley for transmission, and the middle pulley corresponds vertically to the device body.

[0012] In some feasible embodiments, the coupling includes an outer cylinder and an inner cylinder, the inner cylinder being telescopically disposed inside the outer cylinder, one end of the inner cylinder corresponding to the pivot in the middle of the pulley; one end of the inner cylinder abuts against the bottom of the inner cavity of the outer cylinder via a spring, and the other end of the inner cylinder is provided with a mating part corresponding to the pivot of the suspension wheel, so as to facilitate the positioning and connection of the coupling and the pivot of the suspension wheel.

[0013] In some feasible embodiments, a connecting plate is provided to connect the two inner cylinders on the front support rod.

[0014] In some feasible embodiments, the inner cylinder has a sloped side, with the side of the slope closer to the suspension wheel being lower than the side farther from the suspension wheel.

[0015] In some feasible embodiments, the end of the shaft of the suspension wheel facing the docking portion is provided with an end face groove; the docking portion is provided with a bearing for fitting into the end face groove of the shaft of the suspension wheel; a positioning insert shaft is provided on the end face of the docking portion facing the suspension wheel, and a slot adapted to the positioning insert shaft is provided in the end face groove.

[0016] In some feasible embodiments, the guide rope clamping part includes an elastic band with perforations. The device body has barbs that hook onto the portion of the elastic band between the perforations. One end of the elastic band is fixedly connected to the device body, and the other end is a free end, used to create a space between the elastic band and the device body for clamping the guide rope when the barbs hook onto the elastic band through the perforations. Alternatively, the guide rope clamping part includes a clamping seat with clamps for clamping the guide rope. A second motor is installed inside the device body and is connected to the clamps for controlling opening and closing. Alternatively, the guide rope clamping part is a binding rope installed on the device body. Alternatively, the guide rope clamping part is a clip installed on the device body.

[0017] In some feasible embodiments, the automatic traction and laying device for overhead lines further includes a control unit, which includes a control component for controlling the drive component, and a communication component communicatively connected to the control component, which receives signals and sends instructions to the control component.

[0018] In some feasible embodiments, the automatic traction and laying device for overhead lines also includes a ranging radar located at the front and rear ends of the main body of the device. The ranging radar is communicatively connected to the control unit and is used to send a signal to the control unit after detecting an obstacle at a pre-approved distance in the forward direction. The control unit controls the forward speed of the drive component.

[0019] In some feasible embodiments, a camera is also provided on the lower side of the main body of the device, which is communicatively connected to the control unit. Attached Figure Description

Detailed Implementation

[0040] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of the present invention are only used to explain the present invention and are not intended to limit the present invention.

[0041] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the invention. However, it will be apparent to those skilled in the art that these specific details are not necessary to practice the invention. In other embodiments, well-known structures, circuits, materials, or methods have not been specifically described in order to avoid obscuring the invention.

[0042] Throughout this specification, references to "an embodiment," "an example," or "an example" mean that a particular feature, structure, or characteristic described in connection with that embodiment or example is included in at least one embodiment of the present invention. Therefore, the phrases "an embodiment," "an example," "an example," or "an example" appearing in various places throughout the specification do not necessarily refer to the same embodiment or example. Furthermore, specific features, structures, or characteristics can be combined in one or more embodiments or examples in any suitable combination and / or sub-combination. Moreover, those skilled in the art will understand that the illustrations provided herein are for illustrative purposes and are not necessarily drawn to scale. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0043] In the description of this invention, the terms "front", "rear", "left", "right", "up", "down", "vertical", "horizontal", "high", "low", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and 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. Therefore, they should not be construed as limiting the scope of protection of this invention.

[0044] A blowout preventer (BOP) is used during well testing, workover, and completion operations to close the wellhead and prevent blowouts. It combines full and partial sealing functions into one device, featuring simple structure, ease of operation, and high-pressure resistance. It is a commonly used safety sealing device in oilfields to prevent blowouts. During oil drilling, it is installed on the wellhead casing head to control the flow of high-pressure oil, gas, and water. When the oil and gas pressure inside the well is very high, the BOP can seal the wellhead completely. When heavy mud is injected from the drill pipe, a four-way valve under its gate can replace the mud affected by gas, increasing the pressure of the fluid column inside the well to suppress the ejection of high-pressure oil and gas.

[0045] For the aforementioned blowout preventers, the current locking devices include manual locking or automatic locking. However, in the current case of manual locking, if automatic locking fails, the cause of the failure cannot be detected in time. Furthermore, there may be a linkage between the manual and automatic locking components when manual locking is used, meaning that manual locking may still pose a risk of failure, resulting in an unreliable safety threat. Therefore, this embodiment addresses this situation by providing the following implementation plan.

[0046] Example 1

[0047] Reference Figures 1 to 11 An automatic traction and cable laying device for overhead lines includes a main body 1, a rope clamping part 2, and a traveling part 3. The rope clamping part 2 is disposed on the main body 1 and is used to clamp the rope 200. The traveling part 3 is disposed above the main body 1 and is movably connected to the tower ground wire 100. The traveling part 3 is equipped with a drive assembly that drives it to move forward or backward on the ground wire, so that the main body 1 can move suspended on the ground wire. The traveling part 3 includes symmetrical brackets located on both sides of the main body 1. One bracket is provided with a suspension wheel 310 for suspending on the ground wire. The suspension wheel is equipped with the drive assembly. The other bracket is provided with a coupling 320 corresponding to the rotating shaft of the suspension wheel 310. The coupling 320 has a retractable docking part 321 for engaging with the rotating shaft of the suspension wheel 310. When the docking part 321 is retracted, a gap that allows the ground wire to pass through appears between the docking part 321 and the rotating shaft of the suspension wheel 310.

[0048] In use, this automatic traction and cable laying device only requires the worker to connect the suspension wheel 310 of its walking part 3 to the existing ground wire of the overhead line, that is, to retract the aforementioned docking part 321. A gap is created between the docking part 321 and the rotating shaft of the suspension wheel 310, allowing the ground wire to pass through. The suspension wheel 310 of this device is then suspended on the ground wire. In this way, by utilizing the existing ground wire, this device can directly use the bottom line as a track to move. The guide rope is clamped on the aforementioned guide rope clamping part 2. This traction and cable laying device brings the guide rope to the pole on the other side, where the worker on the other pole receives it to complete the traction and cable laying. The aforementioned drive assembly can be implemented by using a motor to drive the suspension wheel 310. The motor can be located on the outer wall of the bracket connecting the shaft of the suspension wheel 310, or it can be mounted on the end of the bracket. Alternatively, a motor can be used to drive a transmission box, which transmits force to the shaft of the suspension wheel 310 through gears, worm gears, connecting rods, or racks in the transmission box. The shaft drives the suspension wheel 310 to rotate. The shaft can be fixedly connected to the suspension wheel 310 through welding, keying, or flange connections.

[0049] This device allows for the deployment and unloading of the guide rope under manual control, reducing the frequency of manual rope deployment and lowering operational risks. Compared to using unmanned aerial vehicles, this device simplifies the required three-dimensional spatial (aerial control) control to one-dimensional control (using the existing ground wire as a guide rail; the worker only needs to start the device). This greatly simplifies the operation of unmanned guide rope deployment, making it easy for general workers to operate. Furthermore, relying on the existing ground wire support, this device does not require a complex and powerful drive motor, allowing for a compact design that is very convenient for workers to carry. Operation requires only three steps: suspend the device on the ground wire, clamp the guide rope, and start the device to complete the operation. The drive component in this embodiment can be a motor located on the side of the suspension wheel 310. The motor control button can be located on the bracket, directly on the motor, or on the main body 1, and the motor can be started via wireless or wired communication. Alternatively, the motor control component can be separated from the main body 1 and controlled remotely.

[0050] Based on the above embodiments, further optimizations can be made. The support includes a front support rod 330 and a rear support rod 340. The front support rod 330 is a folded rod structure, with its bend rotatably connected to the main body 1 of the device, and both ends located above the main body 1. The rear support rod 340 is a straight rod structure, with one end rotatably connected to the main body 1 of the device. The suspension wheel 310 includes a front pulley 311, a middle pulley 312, and a rear pulley 313. The front pulley 311 and the middle pulley 312 are respectively located at the ends of the front support rod 330 away from and near the rear support rod 340, with the front pulley 311 located in front of the main body 1. The rear pulley 313 is located at the other end of the rear support rod 340.

[0051] Combination Figure 10 and Figure 11 This solution addresses the characteristic of ground wires drooping downwards and acting as "tracks." To enable a small, lightweight (the weight of this device is sufficient for the suspension wheel 310 to provide sufficient grip and friction for movement on the ground wire) automatic traction and laying device to move stably and evenly along the ground wire, this automatic traction and laying device employs a front and rear support rod design. The front support rod 330 uses a branched, folded rod style, while the rear support rod 340 uses a single straight rod style. Three sets of pulleys are used; the first two pulleys are arranged on the front support rod 330, with the middle pulley providing power. The front support rod 330 uses a two-wheel structure connected by the same support rod, ensuring that the support structure on the drooping ground wire is always supported by the upward supporting force F of the front pulley 311. n1 The lever force causes the middle pulley 312 to be under downward pressure F. pFurthermore, considering the weight of the device itself, a more reliable grip on the ground wire is achieved. This device is self-adjusting based on the degree of ground wire sagging, allowing the central power pulley to more stably drive the main body 1 of the device. Given the current ground wire sagging, the main body 1 of the device can be stably positioned approximately parallel to the tangent of the suspended ground wire. The aforementioned support can also utilize components that maintain their shape under normal conditions, such as column springs, leaf springs, torsion springs, and rubber connectors, to connect the support to the main body 1.

[0052] Example 2

[0053] Based on the above embodiment, the rear support rod 340 is rotatably connected to the device body 1 via a connecting shaft, and a torsion elastic element is fitted on the connecting shaft. One end of the torsion elastic element is connected to the device body 1, and the other end is connected to the rear support rod 340. This rear support rod 340 is a single rod, and under normal conditions, the rear pulley 313 of the rear support rod 340 is aligned with the front pulley 311 and the middle pulley 312.

[0054] The front support rod 330 is rotatably connected to the device body 1 via a connecting shaft, and a torsion elastic element (not shown in the figure) is fitted on the connecting shaft. One end of the torsion elastic element is connected to the device body 1, and the other end is connected to the rear support rod 340. When the torsion elastic element is relaxed, the front pulley 311 is located in front of the device body 1.

[0055] As mentioned above, to address the issue of ground wire sagging, a structure with two different support rods and three sets of pulleys is adopted. This serves two purposes: firstly, to ensure the device achieves front-to-back balance; and secondly, through the setting of torsion elastic elements, not only does it keep the suspension wheel 310 at a suitable position above the device when not in operation, making it convenient for workers to hang it up, but it also provides a certain degree of shock absorption during the device's movement, ensuring that ground wire vibration and swaying during movement will not significantly affect the contact between the suspension wheel 310 and the ground wire, thus ensuring the stability of the device's movement.

[0056] Example 3

[0057] Based on the above embodiment 1 or 2, the rope clamping part 2 is located on the lower side of the device body 1 and corresponds vertically to the front support rod 330, so as to stabilize the rope clamping part 2 on the device body 1 by means of two points on the folding rod structure that are grounded, so as to prevent the rope clamping part 2 from swinging back and forth on the device body 1 too much.

[0058] The front pulley 311 and rear pulley 313 are driven pulleys; the middle pulley 312 is the driving pulley; a first motor 4 is provided at one end of the front support rod 330 near the rear support rod 340; the first motor 4 is connected to the middle pulley 312 in a transmission connection, and the middle pulley 312 corresponds vertically to the main body 1 of the device. The middle pulley is set as the driving pulley, and the front and rear pulleys are set as driven pulleys, so as to ensure that the driving component that provides power can be located above the center of the main body of the device.

[0059] Example 4

[0060] Based on any of the above embodiments 1 to 3, the coupling 320 includes an outer cylinder 3201 and an inner cylinder 3202. The inner cylinder 3202 is telescopically disposed inside the outer cylinder 3201. One end of the inner cylinder 3202 corresponds to the pivot in the middle of the pulley. One end of the inner cylinder 3202 abuts against the bottom of the inner cavity of the outer cylinder 3201 through a spring. The other end of the inner cylinder 3202 is provided with the docking part 321 corresponding to the pivot of the suspension wheel 310, so as to facilitate the positioning and connection of the coupling 320 and the pivot of the suspension wheel 310.

[0061] This embodiment can be further optimized, such as... Figure 7 As described above, one side of the inner cylinder 3202 is inclined, and the side of the inclined surface closer to the suspension wheel 310 is lower than the side farther away from the suspension wheel 310. With this structure, the worker only needs to align one side of the inclined surface with the ground wire, and the ground wire will slide into the inside of the support rod, so that the worker can quickly and easily hang the suspension wheel 310 on the ground wire.

[0062] Example 5

[0063] Based on any of the above embodiments 1 to 4, the end of the shaft of the suspension wheel 310 facing the docking portion 321 is provided with an end face groove 314; the docking portion 321 is provided with a bearing 322 for fitting into the end face groove 314 of the shaft of the suspension wheel 310; a positioning insert shaft 323 is provided on the end face of the docking portion 321 facing the suspension wheel 310, and a slot 315 adapted to the positioning insert shaft 323 is provided in the end face groove 314. Here, the bearing 322 can be a roller bearing 322 or a sliding bearing 322.

[0064] Example 6

[0065] like Figures 12 to 15The difference between this embodiment and any of the above embodiments is that, in this embodiment, the bracket on one side of the coupling is connected to the lower edge of the device body via a spring hinge 5, allowing the bracket on this side to be rotated around the spring hinge 5. When returning to its original position, the coupling corresponds to the rotation axis of the suspension wheel. Using this embodiment, when the worker operates the device on the tower, there is no need to sequentially separate the three couplings 320. The worker can directly pry open the entire bracket on one side to create a large gap for the ground wire. Alternatively, the worker can easily operate with one hand, holding the bracket on one side while the other side of the bracket connects to the device body 1. Through gravity, the bracket rotates around the aforementioned spring hinge 5 to create a large gap for the ground wire, allowing the suspension wheel 312 to be hung on the ground wire.

[0066] Example 7

[0067] Combination Figure 16 Based on the above embodiments, this embodiment provides a connecting plate 7 that connects the two inner cylinders 3202 on the front support rod 330. The connecting plate 7 connects the two inner cylinders 3202. By simply turning the connecting plate 7, the two inner cylinders 3202 can be operated at the same time, instead of moving the three inner cylinders 3202 one by one.

[0068] Example 8

[0069] Based on any of the above embodiments 1 to 7, the rope clamping part 2 includes an elastic band 2a with perforations. The device body 1 is provided with barbs 110 that hook the portion of the elastic band 2a between the perforations. One end of the elastic band 2a is fixedly connected to the device body 1, and the other end is a free end. This allows the elastic band 2a to form a space between itself and the device body 1 for clamping the rope when the barbs 110 pass through the perforations and hook the elastic band 2a. The rope clamping part 2 in this embodiment is simple to design, easy to operate, and convenient to manufacture.

[0070] Example 9

[0071] Combination Figure 17 and Figure 18 Based on any of the above embodiments 1 to 7, the guide rope clamping part 2 includes a clamping seat 210, on which a clamp 220 for clamping the guide rope is provided. A second motor is provided inside the main body 1 of the device, and the second motor is connected to the clamp 220 for controlling opening and closing. Using this clamp 220, the clamping of the guide rope can be controlled by adjusting the second motor, as described below, by controlling the second motor. The advantage is that there is no need for manual removal of the clamped part, and the clamping force can be adjusted.

[0072] Of course, the rope clamping part 2 here can also be simplified, for example, it can be a binding rope set on the main body 1 of the device, or the rope clamping part 2 can be a clip set on the main body 1 of the device.

[0073] Example 10

[0074] Based on any of the above embodiments, the automatic traction and wire laying device for overhead lines further includes a control unit. The control unit includes a control component for controlling the drive component, and a communication component that is communicatively connected to the control component. The communication component is used to send instructions to the control component after receiving signals.

[0075] This automatic traction and cable-laying device for overhead lines also includes ranging radars located at the front and rear ends of the main body 1.
