Description

Technical Field

[0001] The present application relates to the technical field of high-altitude operations on power lines, and in particular to a flexible track throwing device based on drone-based overhead transmission lines. Background Art

[0002] As the length of transmission lines continues to increase, the amount of high-altitude maintenance and construction work on the lines is also increasing. At the same time, in order to meet the mechanized and intelligent operation of overhead transmission lines, it is necessary to establish a flexible track system in the air and on the ground, that is, the ground wire needs to be connected to the ground to form a passage for lifting load-bearing equipment and operating personnel.

[0003] Among them, related technologies mostly use ropes and hooks to establish a connection between the ground and the air, so as to carry out high-altitude operations. However, the strength of the ropes is not ideal under some complex working conditions. Therefore, it is more important to use flexible tracks instead of ropes to establish a passage for workers in the air and on the ground. At the same time, the flexible track has the following characteristics: 1. The flexible track has strong bearing capacity and good anti-breaking performance, and is a commonly used load-bearing tool; 2. The flexible track has good flexibility and small curvature. The flexible track can provide better protection for the coated wires and ground wires, and the coating effect of the flexible track is better; 3. The flexible track can achieve a better insulation level as required, and can effectively realize the connection from equipotential to ground potential.

[0004] However, the existing devices for establishing air-to-ground operation channels only support throwing operations similar to slender ropes such as ropes, hooks and sports ropes, and cannot effectively clamp larger flexible tracks for precise throwing and establishment operations. At the same time, due to the lack of equipment suitable for flexible track throwing, the air-to-ground operation channel formed by the flexible track lacks a more reasonable setting during actual operation.

[0031] It should be noted that the terms "first", "second", etc. in the description and claims of this application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0032] The terms "comprises" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus that includes a series of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, product or apparatus.

[0033] As a preferred embodiment, the present application provides a flexible track throwing device 1 based on a UAV overhead power transmission line, see Figures 1 to 7 The flexible track throwing device 1 includes: a drone 10; a thrower body 20, the thrower body 20 is connected to the drone 10, the thrower body 20 is provided with a control component 21, the drone 10 is used to drive the thrower body 20 to move in three-dimensional space; a flexible track component 30, the flexible track component 30 is connected to the thrower body 20, and the flexible track component 30 includes: a flexible track disc 31 and a flexible track bracket 32, the flexible track disc 31 is used to accommodate and place the flexible track 40, one end of the flexible track bracket 32 is connected to the thrower body 20 in a removable manner, and the flexible track disc 31 is connected to the flexible track bracket 32; wherein, the drone 10 carries the thrower body 20 and runs to ride above the wire 2, and the flexible track component 30 is controlled by the control component 21 to detach from the thrower body 20, and the flexible track 40 is respectively located on both sides of the wire 2 to realize the air-to-ground laying of the flexible track 40.

[0034] The drone 10 is specifically a drone device, preferably a drone with a strong carrying capacity. Depending on the working conditions, the drone 10 can be replaced by a crane or a manned aircraft for transportation. The operator can remotely control the drone 10 for remote operations. The drone 10 is compact and has strong spatial mobility, making it suitable for high-altitude operations. Therefore, during the specific operation, the drone 10 carries the thrower body 20 to perform high-altitude operations.

[0035] The kicker body 20 is provided with a control assembly 21, and the control assembly 21 is provided with a main control board. The operator can remotely issue instructions to control the kicker body 20 to perform the throwing action. At the same time, the main component of the air-to-ground operation channel: the flexible track 40, is carried by the flexible track assembly 30 in this application. Due to the particularity of the flexible track 40, the flexible track 40 is a wide-body track, and its weight is different from the general bar rope structure. Therefore, the application document provides a structure of a flexible track disc 31 and a flexible track bracket 32. The flexible track 40 is loaded on the flexible track disc 31, which plays a certain accommodating role for the flexible track 40, so that the flexible track 40 has a certain regularity before being laid, and the flexible track bracket 32 provides a fastening connection effect. Since the flexible track disc 31 mainly provides the accommodation property, the strength of the flexible track disc 31 is not enough to be directly connected to the ejector body 20. Therefore, in this application, the flexible track disc 31 is externally connected to the flexible track bracket 32, which is connected to the ejector body 20 through the flexible track bracket 32 to achieve a stable connection between the flexible track disc 31 and the ejector body 20, thereby improving the transportation stability of the flexible track disc 31, and realizing a more accurate flexible track 40 delivery through the drone 10 and the ejector body 20.

[0036] Therefore, during the implementation of the above scheme, the drone 10 is connected to carry the thrower body 20 and flies to the top of the power tower 3, aligns with the wire 2 locked on the power tower 3, and uses the control component 21 to control the flexible track disk 31 in the flexible track component 30 to throw one side of the flexible track 40. After the flexible track 40 on one side lands, the flexible track disk 31 is controlled to throw the other side of the flexible track 40, so that the flexible track 40 is located on both sides of the wire 2 to form an air-to-ground operation channel.

[0037] As a preferred embodiment, the thrower body 20 includes: a thrower main board 22, which is connected to support the flexible track assembly 30; a thrower leg assembly 23, which is used to support the thrower body 20, and the thrower main board 22 is connected to one end of the thrower leg assembly 23, and the other end of the thrower leg assembly 23 is connected to the drone 10.

[0038] Specifically, the main part of the kicker body 20 is composed of the kicker mainboard 22. The kicker mainboard 22 is a flat plate structure, preferably made of aluminum, which is relatively light and lightweight. The side of the kicker mainboard 22 is provided with reinforcing ribs, and there are preferably two reinforcing ribs, which are located on the opposite sides of the longer side of the kicker mainboard 22. The material is preferably carbon fiber, which has high strength while ensuring lightness.

[0039] The main function of the thrower is to connect and fix the flexible track assembly 30, and the thrower leg assembly 23 is mainly used to connect with the drone 10. At the same time, the thrower leg assembly 23 is used to support the throwing device when it is on the ground. The longitudinal length of the thrower leg assembly 23 is longer than the longitudinal length of the flexible track bracket 32. When the flexible track throwing device 1 is on the ground, it can effectively prevent the flexible track assembly 30 from scratching the ground.

[0040] Therefore, the present application can effectively improve the structural stability of the flexible track throwing device 1 by connecting the thrower leg assembly 23 to the drone 10.

[0041] As another preference, the flexible track assembly 30 also includes: a first flexible track assembly 33, the first flexible track assembly 33 is connected to one end of the kicker main board 22; a second flexible track assembly 34, the second flexible track assembly 34 is connected to the other end of the kicker main board 22, and the first flexible track assembly 33 and the second flexible track assembly 34 are located at both ends of the kicker main board 22 and are arranged opposite to each other.

[0042] Among them, there are multiple flexible track components 30 in the present application document. As mentioned above, there are preferably two flexible track components 30 in the present application document, the first flexible track component 33 and the second flexible track component 34. The two track components can operate at the same time, and the laying efficiency of the air-to-ground operation channel is higher.

[0043] Therefore, the arrangement of the first flexible track assembly 33 and the second flexible track assembly 34 can further improve the working efficiency of the flexible track throwing device 1 in this application document.

[0044] Further preferably, the first flexible track assembly 33 also includes: a first track plate 331 and a first track bracket 332, the first track plate 331 is connected to one end of the first track bracket 332, and the other end of the first track bracket 332 is connected to the kicker main board 22 in a detachable manner; the second flexible track assembly 34 also includes: a second track plate 341 and a second track bracket 342, the second track plate 341 is connected to one end of the second track bracket 342, and the other end of the second track bracket 342 is connected to the kicker main board 22 in a detachable manner; the flexible track 40 includes: a first flexible track 41 and a second flexible track 42, the first flexible track 41 is wound and arranged in the first track plate 331, the second flexible track 42 is wound and arranged in the second track plate 341, and one end of the first flexible track 41 is connected to one end of the second flexible track 42.

[0045] It should be noted that the first flexible track assembly 33 and the second flexible track assembly 34 have the same structure, that is, in this embodiment, the first track disc 331 and the second track disc 341 have the same structure, the first track bracket 332 and the second track bracket 342 have the same structure, the first flexible track 41 is wound in the first track disc 331, and the second flexible track 42 is wound in the second track disc 341. The first flexible track 41 and the second flexible track 42 are arranged opposite to each other. Therefore, during the operation of the flexible track throwing device 1, the operator only needs to control the drone to fly the thrower assembly above the conductor 2 of the power tower 3, so that the first track disc 331 and the second track disc 341 are respectively located on both sides of the conductor 2, and then control the control assembly 21 to simultaneously lower the first track disc 331 and the second track disc 341. Since the ends of the first flexible track 41 and the second flexible track 42 are connected, after the first track disc 331 and the second track disc 341 touch the ground, the first flexible track 41 and the second flexible track 42 will be respectively located on both sides of the conductor 2 and hang on the conductor 2 to form a convenient aerial carrying channel.

[0046] Preferably, the first flexible track 41 and the second flexible track 42 are integrally formed, that is, the first flexible track 41 is located in the first track plate 331 and extends to transition to the second flexible track 42 in the second track plate 341 .

[0047] See Figure 8 and Figure 9 , the conductor 2 is set on the tower 3, Figure 8 From the perspective of the tower axis, the drone carries the thrower body 20 and flies to the top of the wire 2. After it is in place, the control component 21 throws the flexible track component 30, and the flexible track component 30 falls off. The first flexible track component 33 is located on the right side of the wire 2, and the second flexible track component 34 is located on the left side of the wire 2. Figure 9 From the horizontal perspective of the tower, the flexible track 40 falls on the conductor 2. After the flexible track assembly 30 falls to the ground, the drone carrying the thrower body 20 evacuates, and then the flexible track 40 bearing channel from the conductor 2 to the ground is completed. When the operation is completed, only one end of the flexible track 40 needs to be towed on the ground to dismantle the flexible track 40 bearing channel.

[0048] Furthermore, the flexible track plate 31 includes: a first panel 311 and a second panel 312, an axis 70 is sandwiched between the first panel 311 and the second panel 312, and the flexible track 40 is wrapped around the axis 70; the flexible track bracket 32 also includes: a first bracket 321 and a second bracket 322, one end of the first bracket 321 is connected to the first panel 311, one end of the second bracket 322 is connected to the second panel 312, the first bracket 321 and the second bracket 322 are arranged opposite to each other, the other end of the first bracket 321 extends out of the circumference of the first panel 311, and the other end of the second bracket 322 extends out of the circumference of the second panel 312, and the extended parts of the first bracket 321 and the second bracket 322 are connected by a connecting member 60.

[0049] The above specifically describes the specific structure of the flexible track disk 31. The flexible track 40 is wound between the first panel 311 and the second panel 312. When the flexible track assembly 30 separates from the kicker body 20 and descends, the shaft 70 drives the flexible track 40 to rotate and separate from the flexible track disk 31 to gradually form a strip shape. The setting of the first panel 311 and the second panel 312 plays a certain limiting role on the flexible track 40.

[0050] Similarly, the first bracket 321 and the second bracket 322 are used to support and connect the flexible track plate 31. In this embodiment, the first bracket 321 and the second bracket 322 have the same structure and are provided with multiple connecting parts 60. The connecting part 60 is specifically a double-headed positioning bolt, wherein the bottom end extension part of the first bracket 321 and the second bracket 322 are connected through the connecting part 60, so that the connecting part 60 plays a certain supporting role on the flexible track plate 31, and the top end extension part of the first bracket 321 and the second bracket 322 are also connected through the connecting part 60. At this time, the connecting part 60 plays a certain reinforcing role on the flexible track plate 31, and at the same time facilitates the first bracket 321 to cooperate with the second bracket 322 to connect with the kicker main board 22.

[0051] Preferably, since the first bracket 321 and the second bracket 322 have the same structure, taking the first bracket 321 as an example, the first bracket 321 is a segmented split bracket structure, with the shaft 70 as the end connection point. The upper half of the first bracket 321 extending out of the flexible track plate 31 is regarded as the first section, and the end of the first section is fixedly connected around the shaft 70. Similarly, the lower half of the first bracket 321 extending out of the flexible track 40 is regarded as the second section, and the end of the second section is fixedly connected around the shaft 70. Under the premise of ensuring the supporting strength of the first bracket 321, the segmented first bracket 321 and the second bracket 322 are easy to disassemble. For example, when the flexible track 40 is damaged, and the first bracket 321 has been connected to the ejector main board 22 with the second bracket 322, it is only necessary to remove the lower half of the first bracket 321 and the second bracket 322, that is, the second section, from the flexible track plate 31, and the flexible track 40 can be repaired, thereby saving repair time and difficulty.

[0052] Specifically, the first bracket 321 is a Y-shaped structure during actual operation, which effectively improves the supporting capacity of the first bracket 321 and the second bracket 322 after being connected by the connecting piece 60, and reduces the risk of the flexible track 40 dragging the tray.

[0053] Furthermore, a kicker bracket 221 and a baffle member 222 are provided at the end of the kicker main board 22. One end of the kicker bracket 221 is slidingly connected to the kicker main board 22, and the other end of the kicker bracket 221 is connected to the flexible track assembly 30 through a pin 223. The separation of the flexible track assembly 30 in the longitudinal direction relative to the kicker main board 22 is controlled by the control assembly 21, and the baffle member 222 stops the separation of the flexible track assembly 30 along the transverse direction of the kicker main board 22.

[0054] Furthermore, the control component 21 includes: a traction rope 211, a kicker bracket 221 is connected to one end of the traction rope 211; a pushing member 212, the pushing member 212 is connected to the kicker main board 22, and the other end of the traction rope 211 is against the pushing member 212; the control component 21 also includes: a guide component 213, the guide component 213 is connected to the kicker main board 22, the traction rope 211 is led out from the kicker bracket 221, extends to abut against the guide component 213, and the guide component 213 guides the traction rope 211 to the pushing member 212.

[0055] Among them, the pushing member 212 is pushed to drive the kicker bracket 221 together with the pin 223 to approach the pushing member 212 through the traction rope 211, so that the flexible track component 30 is longitudinally disengaged from the kicker main board 22, and the guide component 213 can assist the pushing member 212 to make the movement trajectory of the traction rope 211 more reasonable, so as to improve the pushing efficiency of the pushing member 212.

[0056] Furthermore, a flexible track throwing device 1 is preferably provided with a first flexible track component 33 and a second flexible track component 34. Therefore, one end of the traction rope 211 is connected to the kicker bracket 221 part of the first flexible track component 33, and the other end of the traction rope 211 is connected to the kicker bracket 221 part of the second flexible track component 34, and preferably a guide rail traction ring 224 is provided on the kicker bracket 221 to increase the connection stability of the traction rope 211. At this time, the traction rope 211 extends through the guide component 213 and the pusher 212. Preferably, the pusher 212 is an electric push rod, which is extended by remote control. The traction rope 211 drags the kicker bracket 221 on both sides of the kicker main board 22 toward the pusher 212. Preferably, the kicker bracket 221 is a guide rail structure, which can enable the kicker bracket 221 to slide toward the pusher 212, thereby achieving a smoother movement transition. Due to the presence of the baffle 222, the flexible track bracket 32 cannot move toward the middle of the push member 212. Then, when the pin 223 disengages from the flexible track bracket 32, the flexible track bracket 32 falls from the air with the flexible track plate 31, and the flexible track 40 is hung across the wire 2 to form an aerial operation channel. Then, the drone can be controlled to return to the ground with the thrower body 20 to complete the aerial track throwing operation.

[0057] Among them, it should be noted that the flexible track 40 is pressed onto the sleeve 71 of the flexible track disc 31 by fixing screws. The sleeve 71 covers the shaft body 70 and plays a certain protective role on the shaft body 70. At the same time, the flexible track disc 31 is also hollowly sleeved on the sleeve 71, and a sleeve baffle 72 is also provided adjacent to the sleeve 71 to effectively prevent the sleeve 71 from falling out. Therefore, the winding system formed by the above structure allows all parts to rotate freely relative to each other. When the flexible track disc 31 is in the air and landing, the flexible track 40 is slowly withdrawn from the flexible track disc 31 under the protection of the shaft body 70 sleeve 71, and the withdrawal of the flexible track 40 is damping-controlled, so that the landing speed of the flexible track 40 is controlled within the range of 1 meter / second, preventing the flexible track disc 31 from landing too fast and causing damage.

[0058] Furthermore, the kicker leg assembly 23 is connected to the drone 10 through the leg connector 50, and the drone 10 includes a transport leg 11 and an equipment body 12; the equipment body 12 is also the main part of the drone, and the leg connector 50 includes: a first sleeve 51 and a second sleeve 52, the kicker leg assembly 23 passes through the first sleeve 51 and the second sleeve 52 longitudinally, and the transport leg 11 is clamped between the first sleeve 51 and the second sleeve 52; a pressure plate 53, one end of the pressure plate 53 is connected to the first sleeve 51, and the other end of the pressure plate 53 is connected to the second sleeve 52, wherein the pressure plate 53 is connected to the first sleeve 51 and the second sleeve 52 through a pressure plate screw 54, and the pressure plate 53 is used to limit the first sleeve 51 and the second sleeve 52.

[0059] The kicker leg assembly 23 is specifically a trapezoidal structure with good supporting performance. The kicker leg assembly 23 is composed of a pair of relatively arranged kicker legs, wherein a single kicker leg is composed of two kicker leg longitudinal rods 232 and a kicker leg cross rod 231. The kicker leg longitudinal rod 232 and the kicker leg cross rod 231 are connected by a connecting core 233, so that the kicker leg is easy to disassemble and store. At the same time, in order to strengthen the connection strength, a plurality of locking screws 235 are also provided in the connecting core 233. A tube pin 234 is also provided at the lower end of the kicker leg longitudinal rod 232 to increase the shock-absorbing effect. Similarly, the tube pin 234 and the kicker leg longitudinal rod 232 are connected by the connecting core 233 and the locking screw 235.

[0060] Combine Figure 1 and Figure 7 Since it is a connection between the transport leg 11 and the kicker leg assembly 23, the transport leg 11 also includes a longitudinal rod and a transverse rod 111. The transverse rod 111 of the transport leg 11 is selected to be connected with the longitudinal rod 232 of the kicker leg, and the leg connector 50 is cooperated to form a transverse and longitudinal cross structure to improve the connection stability.

[0061] It should be noted that the kicker leg assembly 23 is connected to the kicker main board 22 via bolts, and the bolts are preferably U-bolts 225 to improve the connection strength of the kicker leg assembly 23 relative to the kicker main board 22.

[0062] Further, see Figure 10 In a preferred embodiment, the flexible track assembly 30 is specifically a companion braking structure, and the flexible track bracket 32 is fixedly connected to the flexible track disc 31 through the head pressure plate 83. Specifically, the first section of the flexible track bracket 32 is a hanging frame, one end of the hanging frame 82 is used to connect with the ejector body 20 through the pin hole 80, and the other end of the hanging frame 82 is fixedly connected to the flexible track disc 31 through the head pressure plate 83. The second section of the flexible track bracket 32 is an elastic support frame 86, and the elastic support frame 86 is also fixedly connected to the flexible track disc 31 through the head pressure plate 83. In this embodiment, the first bracket 321 and the second bracket 322 of the flexible track bracket 32 are integrally formed. The end of the elastic support frame 86 is provided with an elastic structure, such as rubber, which is used to reduce the impact and vibration of the flexible track 40 structure after landing to a certain extent. At the same time, a core shaft sleeve 84 is provided on the outside of the shaft body 70 to further protect the shaft body 70 from loss.

[0063] At the same time, the winding crank 85 is connected to the periphery of the shaft body 70, and the winding crank 85 is set through the flexible track disc 31. By providing the winding crank 85 in conjunction with the accompanying brake 81 set on the bracket frame 82, the flexible track disc 31 forms a spoke-type structure. On the basis of reducing the weight by a certain amount, the damping of the rotation of the shaft body 70 is increased, and the outlet speed of the flexible track 40 is accurately controlled. At the same time, the falling speed of the flexible track assembly 30 can be more accurately controlled, thereby avoiding the flexible track disc 31 from being damaged by falling.
