Abstract
Description
Technical Field
[0001] This invention relates to the field of power line and cable construction technology, and in particular to an overhead conductor take-up and drop device, system and method. Background Technology
[0002] Overhead lines mainly refer to exposed overhead lines, erected above the ground. They are power transmission lines where insulators secure the transmission conductors to towers standing upright on the ground to transmit electrical energy. Currently, during the installation and removal of these conductors, a traction device is typically installed on a traveling cable between adjacent towers. This traveling cable is usually a steel cable. The conductor to be installed or removed is connected to a traction robot, which controls the traction device to move along the traveling cable to complete the installation or removal of the conductor. Existing traction devices connect to the traveling cable via multiple sets of wheels, moving along the cable by driving these wheels. However, in actual operation, the traveling cable between adjacent towers may bend and sag under gravity, and external environmental factors such as strong winds and heavy rain can also cause localized bending and deformation. This can prevent the traveling wheels from maintaining close contact with the cable, leading to slippage and bouncing, thus affecting the normal operation of the traction device. Summary of the Invention
[0003] The purpose of this invention is to provide an overhead conductor take-up and drop device, system and method to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.
[0004] The technical solution adopted to solve the above-mentioned technical problems is as follows:
[0005] This invention provides an overhead conductor retraction device, comprising:
[0006] frame;
[0007] A moving component includes a moving drive mechanism and a moving clamping mechanism mounted on the frame. The moving drive mechanism includes multiple drive wheels and a moving drive structure. The moving clamping mechanism includes multiple clamping wheels and a clamping drive structure. The multiple drive wheels are spaced apart along a first direction, and the multiple clamping wheels are respectively disposed between two adjacent drive wheels. The clamping drive structure is used to drive the multiple clamping wheels to reciprocate along a second direction to clamp the traveling cable between the multiple clamping wheels and the multiple drive wheels along the first direction. The multiple clamping wheels slide relative to the clamping drive structure along the second direction. The device is configured such that multiple drive wheels are slidably disposed relative to the frame along a second direction, each drive wheel is connected to a first elastic element, and each clamping wheel is connected to a second elastic element. The second elastic element provides the clamping wheel with a constant elastic force to keep pressing the traveling cable, and the first elastic element provides the drive wheel with a constant elastic force to keep pressing the traveling cable, so as to adapt to the bending deformation of the traveling cable. The moving drive structure is used to drive the multiple drive wheels to rotate, so as to drive the overhead wire take-up and drop device to move along the traveling cable. The second direction is perpendicular to the first direction.
[0008] A mounting assembly is installed on the outside of the frame and is used to connect to the power transmission line.
[0009] The advantages of the overhead conductor take-up and drop device of the present invention are:
[0010] In use, the traveling cable is positioned between multiple clamping wheels and multiple drive wheels along a first direction.

When clamping the traveling cable, a second elastic element provides a constant elastic force to the clamping wheels to keep the traveling cable pressed against it, and a first elastic element provides a constant elastic force to the drive wheels to keep the traveling cable pressed against it. If the traveling cable bends or sags under gravity, or if it is affected by the external environment and becomes locally bent or deformed, the multiple clamping wheels and multiple drive wheels can be kept pressed against the traveling cable at all times, thus avoiding slippage and improving the driving force. Furthermore, the overhead wire take-up and release device will not jump with the bending and deformation of the traveling cable, allowing the overhead wire take-up and release device to move smoothly on the traveling cable.

[0052] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are some embodiments of the present invention, not all embodiments.
[0053] Reference Figures 1 to 7 The overhead conductor take-up and take-up device 100 of the present invention is provided in the following embodiments:
[0054] like Figure 1 As shown, the overhead conductor winding and unwinding device 100 of this embodiment includes: a frame 200, a moving component 300, and a hanging component 400. The moving component 300 and the hanging component 400 are mounted on the frame 200. In this embodiment, the moving component 300 is used to drive the entire overhead conductor winding and unwinding device 100 to move on the traveling cable 500, while the hanging component 400 is used to connect the power transmission line 600, which can be a cable, optical cable, etc.
[0055] To more clearly describe the positional relationship between the various components, this embodiment defines a first direction, a second direction, and a third direction. The first direction is defined as the front-to-back direction. In some other embodiments, the first direction may be other directions depending on the extension direction of the hanging cable 500. The first direction, the second direction, and the third direction are orthogonal to each other, and the second direction is the up-down direction, while the third direction is the left-right direction.
[0056] like Figure 1As shown, the moving component 300 in this embodiment includes a moving drive mechanism 310 and a moving clamping mechanism 320 mounted on the frame 200. The moving drive mechanism 310 includes a plurality of drive wheels 311 and a moving drive structure 312. The axis of the drive wheels 311 extends in the left-right direction, and the plurality of drive wheels 311 are arranged at intervals in the front-back direction.
[0057] like Figure 1 As shown, the movable clamping mechanism 320 of this embodiment includes multiple clamping wheels 321 and a clamping drive structure 322. The axes of the multiple clamping wheels 321 extend in the left-right direction, and the multiple clamping wheels 321 are respectively disposed between two adjacent drive wheels 311. The clamping drive structure 322 is used to drive the multiple clamping wheels 321 to move back and forth in the up-down direction, so as to clamp the traveling cable 500 in the left-right direction between the multiple clamping wheels 321 and the multiple drive wheels 311. It can be understood that the multiple drive wheels 311 in this embodiment are located at... The upper side of the traveling cable 500 is occupied by multiple clamping wheels 321, while the lower side of the traveling cable 500 is occupied by multiple clamping drive structures 322. The multiple clamping wheels 321 abut against the bottom of the outer periphery of the traveling cable 500, while multiple drive wheels 311 abut against the top of the outer periphery of the traveling cable 500 to clamp the traveling cable 500. The moving drive structure 312 is used to drive the multiple drive wheels 311 to rotate, thereby driving the overhead wire take-up and drop device 100 to move along the traveling cable 500.
[0058] In this embodiment, the drive wheel 311 and the clamping wheel 321 are staggered in the vertical direction, which can reduce the number of clamping wheels 321. The number of clamping wheels 321 only needs to be one less than the number of drive wheels 311. In this embodiment, there are three drive wheels 311 and two clamping wheels 321. Furthermore, it can adapt to the local deformation of the walking cable 500, making the movement smoother.
[0059] In this invention, multiple clamping wheels 321 are slidably disposed relative to the clamping drive structure 322 in the vertical direction, and multiple drive wheels 311 are slidably disposed relative to the frame 200 in the vertical direction, such as... Figure 2 As shown, multiple drive wheels 311 are respectively connected to a first elastic element 313, such as... Figure 3 As shown, multiple clamping wheels 321 are respectively connected to second elastic members 323. The second elastic members 323 are used to provide the clamping wheels 321 with an elastic force that keeps pressing the travel cable 500. The first elastic member 313 is used to provide the drive wheel 311 with an elastic force that keeps pressing the travel cable 500, so as to adapt to the bending deformation of the travel cable 500.
[0060] In use, the traveling cable 500 is positioned between multiple clamping wheels 321 and multiple drive wheels 311 in a left-right direction. The clamping drive structure 322 drives the multiple clamping wheels 321 to reciprocate in a up-down direction, thereby clamping and releasing the traveling cable 500. When clamping the traveling cable 500, the second elastic element 323 provides a constant elastic force to the clamping wheels 321 to keep them pressed against the traveling cable 500, and the first elastic element 313 provides a constant elastic force to the drive wheels 311 to keep them pressed against the traveling cable 500. Figure 4 As shown, if the walking cable 500 bends and sags under the action of gravity, or if the walking cable 500 is affected by the external environment and causes local bending deformation, it can ensure that the multiple clamping wheels 321 and multiple driving wheels 311 always keep pressed against the walking cable 500, thereby avoiding slippage, improving the driving force of walking, and the overhead wire winding and unwinding device 100 will not jump with the bending deformation of the walking cable 500, so that the overhead wire winding and unwinding device 100 can move smoothly on the walking cable 500.
[0061] Regarding the specific structure of the mobile drive structure 312, such as Figure 1 and Figure 2 As shown, the mobile drive structure 312 of the present invention includes a transmission belt 3121, a plurality of guide pulleys 3122, a plurality of transmission pulleys 3123, a plurality of tension pulleys 3124, and a mobile drive component (not shown). The plurality of transmission pulleys 3123 are coaxially and fixedly connected to the plurality of drive wheels 311 in a one-to-one correspondence. The plurality of guide pulleys 3122 are rotatably and fixedly installed on the frame 200. In this embodiment, there are two guide pulleys 3122. The two guide pulleys 3122 are spaced apart at the front and rear ends of the plurality of transmission pulleys 3123 in the front-back direction. The axes of the guide pulleys 3122, transmission pulleys 3123, and tension pulleys 3124 are all arranged in the left-right direction.
[0062] The transmission belt 3121 is connected between multiple guide pulleys 3122 and multiple transmission pulleys 3123, while multiple tension pulleys 3124 are respectively disposed between two adjacent transmission pulleys 3123. In this embodiment, two tension pulleys 3124 are provided. The tension pulleys 3124 are slidably mounted on the frame 200 and abut against the outer peripheral wall of the transmission belt 3121. Each tension pulley 3124 is connected to a third elastic element 3125. The third elastic element 3125 is used to provide the tension pulley 3124 with an elastic force to press the transmission belt 3121 against the transmission pulley 3123. The moving drive component is connected to one of the guide pulleys 3122.
[0063] In this embodiment, a single moving drive component drives one of the guide pulleys 3122 to rotate. The transmission belt 3121 then drives multiple transmission pulleys 3123 to rotate synchronously, thereby driving multiple drive wheels 311 to rotate synchronously. This eliminates the need for multiple moving drive components, simplifying the driving method. In this case, the moving drive component is a servo motor, meaning that in this embodiment, a single servo motor can drive multiple drive wheels 311 to rotate.
[0064] When multiple drive wheels 311 reciprocate in the up and down direction, the transmission pulley 3123 will also move accordingly. At this time, under the elastic force of the third elastic element 3125, the tension pulley 3124 adjusts the tension of the transmission belt 3121 so that the transmission belt 3121 is always pressed against the transmission pulley 3123 and will not separate.
[0065] The transmission belt body 3121 can be a belt or chain structure.
[0066] In this embodiment, the frame 200 is provided with a fixed crossbeam 210 extending in the front and rear directions. The tensioning pulley 3124 is connected to the tensioning sliding frame 3126. The tensioning pulley 3124 is rotatably mounted on the tensioning sliding frame 3126. The tensioning sliding frame 3126 slides in the up and down direction on the fixed crossbeam 210. The third elastic element 3125 acts between the fixed crossbeam 210 and the tensioning sliding frame 3126.
[0067] The drive wheel 311 is connected to the first sliding frame 3111. The drive wheel 311 is rotatably mounted on the first sliding frame 3111. The first sliding frame 3111 slides along the vertical direction on the fixed crossbeam 210. The first elastic element 313 acts between the first sliding frame 3111 and the fixed crossbeam 210.
[0068] Specifically: the top of the first sliding frame 3111 is provided with a first guide rod 3112 extending in the vertical direction, the top of the tensioning sliding frame 3126 is provided with a tensioning guide rod 3127 extending in the vertical direction, and the fixed crossbeam 210 is provided with a first guide hole 211 that slides with the first guide rod 3112 and a tensioning guide hole that slides with the tensioning guide rod 3127 (not shown in the figure).
[0069] The upper end of the tension guide rod 3127 passes through the tension guide hole and is connected to the tension limiting block 3128. The two ends of the third elastic member 3125 abut against the tension limiting block 3128 and the side of the fixed crossbeam 210 facing away from the tension pulley 3124, respectively. It can be understood that the third elastic member 3125 always maintains the tendency to pull the tension guide rod 3127 upward to drive the tension pulley 3124 to move upward, so that the transmission belt 3121 is always pressed upward against the transmission pulley 3123. In this embodiment, the third elastic member 3125 is a spring structure. The third elastic member 3125 is sleeved on the outer periphery of the tension guide rod 3127, and the upper and lower ends of the third elastic member 3125 abut against the top surface of the tension limiting block 3128 and the fixed crossbeam 210, respectively.
[0070] In this embodiment, the upper end of the first guide rod 3112 passes through the first guide hole 211 and is connected to a first limiting block 3113. The two ends of the first elastic member 313 abut against the first sliding frame 3111 and the side of the fixed crossbeam 210 facing the drive wheel 311, respectively. The first limiting block 3113 abuts against the side of the fixed crossbeam 210 facing away from the drive wheel 311. It can be understood that the first elastic member 313 always pushes the first sliding frame 3111 downwards, so that the drive wheel 311 is always pressed tightly against the travel cable 500, and also ensures that the transmission pulley 3123 and the transmission belt body 3121 are in close contact. Figure 2 As shown, when the walking cable 500 bends and deforms, the first elastic elements 313 on both sides are compressed, and at this time the first sliding frame 3111 moves upward with the drive wheel 311. The function of the first limiting block 3113 is to prevent the first guide rod 3112 from dislodging from the first guide hole 211 in its natural state. In this embodiment, the first elastic element 313 is a spring structure. The first elastic element 313 is fitted on the outer periphery of the first guide rod 3112, and the upper and lower ends of the first elastic element 313 abut against the bottom surface of the fixed crossbeam 210 and the top surface of the first sliding frame 3111, respectively.
[0071] It is understandable that each drive wheel 311 has a uniform displacement compensation amount in the vertical direction to adapt to the bending deformation of the walking cable 500. At the same time, when the drive wheel 311 is moving and compensating, the tension pulley 3124 controls the transmission belt 3121 to always press upward against the transmission pulley 3123, so that the transmission belt 3121 can drive each drive wheel 311 to rotate synchronously.
[0072] like Figure 1 and Figure 3As shown, the clamping drive structure 322 of this embodiment includes a clamping sliding seat 3221 and a clamping drive member 3222 that drives the clamping sliding seat 3221 to move in the vertical direction. The clamping wheel 321 is connected to a second sliding frame 3211. The clamping wheel 321 is rotatably mounted on the second sliding frame 3211. The second sliding frame 3211 is slidably mounted on the clamping sliding seat 3221 in the vertical direction. The second elastic member 323 acts between the second sliding frame 3211 and the clamping sliding seat 3221. When clamping the travel cable 500, the clamping drive member 3222 drives the clamping sliding seat 3221 to move upward. When releasing the travel cable 500, the clamping drive member 3222 drives the clamping sliding seat 3221 to move downward. The clamping drive member 3222 of this embodiment uses a linear motor. The clamping sliding seat 3221 of this embodiment is slidably mounted on the frame 200.
[0073] After the clamping drive component 3222 drives the clamping slide seat 3221 to move upward to the set position, each clamping wheel 321 presses the travel cable 500 under the elastic force of the second elastic element 323. When the travel cable 500 bends and deforms, the clamping slide seat 3221 does not move, but the position of the clamping wheel 321 is changed by the elastic force of the second elastic element 323, so as to control the clamping wheel 321 to always keep pressing the travel cable 500.
[0074] Specifically, in this embodiment, the bottom of the second sliding frame 3211 is provided with a second guide rod 3212 extending in the vertical direction, and the clamping sliding seat 3221 is provided with a second guide hole 3223 that slides with the second guide rod 3212. The lower end of the second guide rod 3212 passes through the second guide hole 3223 and is connected to a second limiting block 3213. The two ends of the second elastic member 323 abut against the side of the second sliding frame 3211 and the clamping sliding seat 3221 facing the clamping wheel 321, respectively. The second limiting block 3213 is used to abut against the side of the clamping sliding seat 3221 facing away from the clamping wheel 321.
[0075] Understandably, the second elastic element 323 continuously pushes the second sliding frame 3211 upwards, thereby causing the clamping wheel 321 to remain pressed firmly against the traveling cable 500. Figure 3 As shown, when the walking cable 500 bends and deforms, the second elastic elements 323 on both sides extend and retract. At this time, the second sliding frame 3211 moves upward with the clamping wheel 321. The function of the second limiting block 3213 is to prevent the second guide rod 3212 from dislodging from the second guide hole 3223 in its natural state. In this embodiment, the second elastic element 323 is a spring structure. The second elastic element 323 is fitted around the outer periphery of the second guide rod 3212, and the upper and lower ends of the second elastic element 323 abut against the bottom surface of the second sliding frame 3211 and the top surface of the clamping sliding seat 3221, respectively.
[0076] Furthermore, such as Figure 1 As shown, the overhead wire take-up and take-up device 100 of this embodiment also includes a safety guide assembly. The safety guide assembly includes at least one safety guide mechanism 700 installed on the frame 200. In this embodiment, two safety guide mechanisms 700 are provided, which are respectively provided at the front and rear ends of the device. In some other embodiments, the safety guide mechanism 700 may be provided between two adjacent drive wheels 311.
[0077] like Figure 1 and Figure 5 As shown, the safety guide mechanism 700 of this embodiment includes two guide rollers and a guide drive structure 710. Both guide rollers extend vertically and are parallel to each other horizontally. The guide drive structure 710 drives the two guide rollers to move closer and further apart, controlling the walking cable 500 to be centrally clamped between multiple clamping wheels 321 and multiple drive wheels 311. One guide roller is detachable. It is understood that when the drive wheels 311 and clamping wheels 321 only clamp and limit the walking cable 500 vertically, during operation, the walking cable 500 may move horizontally and detach from the drive wheels 311 and clamping wheels 321, causing the entire device to fall off the walking cable 500. To avoid this risk, this embodiment uses two guide rollers to limit and lock the walking cable 500 in the horizontal direction, preventing the device from accidentally falling off. When disassembling or assembling the device, as... Figure 6 As shown, one of the guide rollers is opened to insert the walking cable 500 from the side between the drive wheel 311 and the clamping wheel 321. After the guide roller is fixedly installed, the two guide rollers are controlled to move closer to each other so that the walking cable 500 is centrally clamped between the multiple clamping wheels 321 and the multiple drive wheels 311. The safety guide mechanism 700 can guide and position the walking cable 500 while also preventing it from falling.
[0078] Specifically, such as Figure 5 As shown, in this embodiment, the guide roller is connected to a connecting shaft 720. The guide roller is rotatably fitted onto the outer periphery of the connecting shaft 720. The upper and lower ends of the connecting shaft 720 are respectively connected to slide blocks 730. The slide blocks 730 are slidably installed on the frame 200 in the left and right direction. The guide roller can rotate as the walking cable 500 moves, reducing friction.
[0079] The guide drive structure 710 of this embodiment is used to drive the two slides 730 at one end to move closer and further apart, thereby driving the two guide rollers to move closer and further apart in the left and right direction. Specifically, the guide drive structure 710 of this embodiment includes a bidirectional screw 711 extending in the left and right direction. The bidirectional screw 711 is threadedly connected to two nut seats 712. The two nut seats 712 are fixedly connected to the two slides 730 respectively. By driving the bidirectional screw 711 to rotate, the two nut seats 712 are synchronously driven to move closer and further apart in the left and right direction, thereby driving the two guide rollers to move closer and further apart.
[0080] The guide rollers include a first guide roller 740 and a second guide roller 750. One end of the connecting shaft 720 on the first guide roller 740 is hinged to one of the slides 730, and the other end is detachably connected to the other slide 730. The two ends of the connecting shaft 720 on the second guide roller 750 are fixedly connected to the two slides 730 respectively. It can be understood that when the overhead wire take-up and drop device 100 is removed from the walking cable 500, the connecting shaft 720 on the first guide roller 740 is disconnected from one of the slides 730, and then the first guide roller 740 is swung to load or unload the walking cable 500 from the side. After that, the connecting shaft 720 on the first guide roller 740 is fixed.
[0081] like Figure 7 As shown, the connecting shaft 720 of this embodiment is provided with a first pin hole 721, and the slide 730 is provided with a second pin hole 731. The first pin hole 721 and the second pin hole 731 are detachably connected by a pin 760.
[0082] Furthermore, in this embodiment, a counterweight 220 is installed at the bottom of the frame 200. The counterweight 220 is used to lower the center of gravity of the entire device, so that the device does not rotate around the circumference of the walking cable 500 during its movement on the walking cable 500. This is equivalent to controlling the drive wheel 311 and the clamping wheel 321 to clamp the walking cable 500 vertically.
[0083] like Figure 1 As shown, the mounting assembly 400 includes a mounting ring 410 connected to the power transmission line 600 and a camera 420 for detecting the traction status of the power transmission line. The mounting ring 410 is located at the front end of the frame 200, while the camera 420 is located below the mounting ring 410 to observe the traction status of the power transmission line 600 in real time.
[0084] In some other embodiments, the overhead conductor winding and unwinding device 100 is also equipped with a battery assembly and a wireless control system. The battery assembly is used to power various power components and is equipped with a large-capacity replaceable battery to meet the needs of long-term and multiple continuous operations, thereby improving construction efficiency. The long-distance wireless control system can provide a communication distance of up to 1000m in open areas to meet the needs of remote operation and adapt to most tower span scenarios.
[0085] like Figure 8 As shown, the present invention proposes an overhead conductor winding and unwinding system, including the above-mentioned overhead conductor winding and unwinding device 100, and also including a winch device 800 connected to the end of the transmission conductor 600 away from the overhead conductor winding and unwinding device 100. The winch device 800 is used to wind and unwind the transmission conductor 600.
[0086] This invention also proposes an overhead conductor winding and unwinding method, applicable to the aforementioned overhead conductor winding and unwinding system, such as... Figure 9 As shown, the overhead conductor winding and unwinding methods include:
[0087] Step S100: Control one of the guide rollers to open, place the travel cable 500 between multiple clamping wheels 321 and multiple drive wheels 311, and then close the guide roller to hang the overhead wire take-up and drop device 100 on the travel cable 500.
[0088] Step S200: Control multiple clamping wheels 321 to press the travel cable 500 and the two guide rollers close to each other, so as to clamp the travel cable 500 in the center between multiple clamping wheels 321 and multiple drive wheels 311;
[0089] Step S300: Control one end of the power transmission line 600 to the hanging assembly 400 and the other end to the winch device 800;
[0090] Step S400: Control multiple drive wheels 311 to rotate, so as to drive the overhead wire take-up and drop device 100 to move along the traveling cable 500;
[0091] Step S500: Control the winch device 800 to wind or unwind the power transmission conductor 600.
[0092] In step S100, the pin 760 on the connecting shaft 720 is pulled out, the first guide roller 740 is swung, and the walking cable 500 is inserted from the side between the multiple clamping wheels 321 and the multiple drive wheels 311. Then the connecting shaft 720 on the first guide roller 740 is fixed.
[0093] In step S200, the clamping drive component 3222 drives the clamping slide seat 3221 to move upward, so as to control the walking cable 500 to be clamped between the multiple clamping wheels 321 and the multiple drive wheels 311. The guide drive structure 710 drives the two guide rollers to move closer to each other, so as to control the walking cable 500 to be centrally clamped between the multiple clamping wheels 321 and the multiple drive wheels 311.
[0094] After the overhead conductor take-up and drop device 100 moves to the end position, the transmission conductor 600 is removed from the hanging ring 410. The control clamping drive component 3222 drives the clamping sliding seat 3221 to move downward. The guide drive structure 710 drives the two guide rollers to move away from each other, release the traveling cable 500, open the first guide roller 740, and remove the overhead conductor take-up and drop device 100 from the traveling cable 500.
[0095] When the travel cable 500 is released, the clamping drive component 3222 drives the clamping slide seat 3221 to move downward. In this embodiment, the clamping drive component 3222 adopts a linear motor, and the clamping slide seat 3221 is slidably mounted on the frame 200.
