Description

Technical Field

[0001] The present invention relates to the field of high-altitude live-line operations, and in particular to a system and method for live-line operations based on unmanned aerial vehicles and electric lifting technology. Background Art

[0002] At present, when carrying out maintenance work on overhead lines, operators are generally required to climb to the cross arm position of the tower, and then use the insulating operating rod to place the pulley on the overhead line. The ground personnel move the pulley to the working position by pulling the rope, thereby providing safe anti-fall protection for the operators. This working method requires the operators to climb the tower in advance, which poses a risk of falling from a height, and the pulley cannot pass over the power components such as the shock-absorbing hammer on the overhead line, resulting in a great limitation on the working scope of this working method. Among the existing improved technologies, there is a method of using drones to build anti-fall components, but this method requires the rope to be set on multiple overhead lines. During the rope building process, the rope will continuously contact and rub against the overhead line, which is easy to damage the insulation skin of the overhead line. Impurities such as metal shavings or dust on the overhead line are easy to enter the insulating rope and affect the insulation effect of the insulating rope, which leads to certain safety hazards in the electrical performance of the constructed operating system, affecting the safety of high-altitude live work.

[0006] Furthermore, a slide groove is provided on the hanger, the bottom of the slide groove is connected to the mounting port, and the transmission shaft is vertically slidably connected in the slide groove.

[0007] Furthermore, a receiving groove for use with a bottom plate is provided at the bottom of the slide groove, and both the bottom plate and the receiving groove are arc-shaped for use with each other.

[0008] Furthermore, the longitudinal section of the limit plate is V-shaped, the bottom end of the V-shape is rotatably connected to the hanger, and the contact end and the limit end are respectively located at two ends of the top of the V-shape.

[0009] Furthermore, a guide hole is provided on the hanger, and the bottom of the hook is slidably connected in the guide hole. A pin is provided at the bottom of the hook, and the pin passes through the guide hole and is rotationally connected to the transmission arm.

[0010] Furthermore, the quick-release connecting ring is provided with an arc groove, a locking ring is rotatably connected in the arc groove, a tension spring is provided between the locking ring and the quick-release connecting ring, the locking ring is provided with an installation port, and the quick-release connecting ring is rotatably connected with limit rods used to cooperate with both sides of the installation port.

[0011] Furthermore, a torsion spring is provided between the limit rod and the quick-release connecting ring, and limit teeth are provided on both sides of the installation opening, and the end of the limit rod is meshed with the limit teeth.

[0012] Furthermore, the limiting rod and the locking ring are both provided with handles, and the bottom of the quick-release connecting ring is provided with a rope hole used in conjunction with the top of the insulating rope ladder.

[0013] Furthermore, the rope installation bolt is provided with a plurality of upper fixing rings, the bottom of the upper fixing ring is rotatably connected with a lower fixing ring, and the lifting rope and the pulling rope are both fixed in the lower fixing ring.

[0014] The live transmission operation method based on drone and electric lifting technology includes the following steps:

[0015] S1. Build the operating system. Connect the drone carrying components, anti-fall protection components, and insulating rope components from top to bottom. Fix the insulating rope ladder to the bottom of the drone body with a quick-release connection ring, then hang the hook on the pylon at the bottom of the insulating rope ladder, and finally fix the lifting rope and pulling rope to the rope installation bolt at the bottom of the pylon;

[0016] S2. The operating system is lifted off, and the drone body drives the completed operating system to move upward toward the overhead line until the mounting port at the bottom of the mounting bracket is located above the overhead line and the drone body stops moving;

[0017] S3, mounting of the operating system, the main body of the drone drives the operating system to move downward toward the overhead line, so that the mounting port at the bottom of the mounting bracket is stuck on the overhead line. During this process, the bottom plate at the bottom of the transmission shaft contacts the overhead line. Under the gravity of the operating system, the mounting bracket slides downward relative to the transmission shaft, that is, the transmission shaft slides upward relative to the mounting bracket, so that the limit step at the top of the transmission shaft passes over the limit plate and is located above the limit end. At the same time, during the upward sliding of the transmission shaft relative to the mounting bracket, the bottom plate drives the locking rod in contact with the top thereof to rotate, so that the bottom ends of the locking rods on both sides rotate relative to each other to close the mounting port, thereby limiting the overhead line within the closed mounting port;

[0018] S4, locking of the operating system. When the bracket slides downward relative to the transmission shaft until the top of the mounting port is completely in contact with the overhead line, the main body of the drone continues to move downward until the insulating rope ladder is separated from the hook. After that, the hook loses the support of the main body of the drone and slides downward relative to the bracket under the action of gravity. Under the connection of the transmission arm, the swing arm is driven to rotate, so that the bottom of the swing arm is separated from the contact end on one side of the limit plate. Under the action of the limit spring, the limit plate rotates toward the transmission shaft, so that the limit end on the other side of the limit plate rotates to the limit step of the transmission shaft, thereby vertically limiting the transmission shaft so that it can no longer slide downward relative to the bracket, and then the lock rod keeps the mounting port closed when there is no external force acting on the hook;

[0019] S5. The operator ascends to perform live-line work. The operator uses a hoist to ascend along the lifting rope to the overhead line to perform live-line work. The ground personnel use the pulling rope to fix the operator's position to ensure the stability of the live-line work;

[0020] S6. Descending of the operator and disassembly of the operating system. After the live operation is completed, the operator descends to the ground along the lifting rope under the action of the elevator. After the main body of the drone rises, the insulating rope ladder is hung on the hook again and the hook is pulled upward, so that the hook slides upward relative to the rack, and the swing arm is driven to rotate in the opposite direction under the connection of the transmission arm, so that the bottom of the swing arm contacts the contact end on one side of the limit plate and then drives the limit plate to rotate, thereby making the limit end on the other side of the limit plate disengage from the limit step, so that the transmission shaft can automatically slide relative to the rack. When the main body of the drone continues to rise and lifts the rack, the rack slides upward relative to the transmission shaft, that is, the transmission shaft slides downward relative to the rack, so that the top end of the locking rod loses the support of the bottom plate and rotates in the opposite direction under the action of gravity, and the bottom ends of the locking rods on both sides rotate away from each other to open the mounting port, so that the rack can be smoothly separated from the overhead line. Thereafter, the main body of the drone drives the operating system to descend to the ground to realize the disassembly of the operating system.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. The present invention uses the drone body to drive the constructed operating system to rise to the overhead line and lock it with the overhead line, so as to achieve effective support and anti-fall protection for the operator's high-altitude operation. The operator does not need to climb the tower in advance to build the operating system. The construction efficiency is higher and the construction process is safer. There is no restriction on the operating position of the overhead line. The position where the drone body can fly can be used for live working, which greatly improves the scope and safety of live working.

[0023] 2. During the construction of the operating system, after the mounting port at the bottom of the mounting bracket is stuck on the overhead line, the bottom plate at the bottom of the transmission shaft contacts the overhead line, and the mounting bracket slides downward relative to the transmission shaft under the action of gravity, that is, the transmission shaft slides upward relative to the mounting bracket. During this process, the limit step at the top of the transmission shaft passes over the limit plate and is located above the limit end, and the bottom plate at the bottom of the transmission shaft drives the locking rods on both sides to rotate during the upward sliding process, so that the bottom ends of the locking rods on both sides rotate relative to each other to close the mounting port, and the overhead line is restricted in the closed mounting port. When the insulating rope ladder at the bottom of the drone body is detached from the hook, the hook slides downward relative to the mounting bracket under the action of gravity, and drives the swing arm to rotate under the connection of the transmission arm, so that the bottom of the swing arm is separated from the contact end on one side of the limit plate, and the limit spring The lower limit plate rotates to rotate the limit end on the other side to the limit step, and the cooperation between the limit end and the limit step is used to limit the vertical position of the transmission shaft to prevent the transmission shaft from sliding downward relative to the bracket, which indirectly keeps the lock rod closed to the mounting port, so that when there is no external force acting on the hook, the bracket remains locked with the overhead line, making the connection between the operating system and the overhead line more convenient and firm, and the insulating rope assembly does not directly contact the overhead line during the construction process, reducing the possible wear on the overhead line, and impurities on the overhead line are not easy to enter the insulating rope assembly and affect the insulation effect, thereby providing safe and effective support and anti-fall protection for operators, greatly simplifying the steps of constructing the operating system, and improving the efficiency and safety of construction;

[0024] 3. The operator uses the elevator to ascend to the working position of the overhead line along the lifting rope, and returns to the original route after the operation is completed. The drone body only needs to hang the insulating rope ladder on the hook again and lift it upward, and then the swing arm can be driven to rotate in the opposite direction under the action of the transmission arm, so that the bottom of the swing arm contacts the contact end on one side of the limit plate and then drives the limit plate to rotate, so that the limit end on the other side is separated from the limit step, thereby automatically releasing the restriction on the vertical position of the transmission shaft. When the bracket continues to be lifted upward, the transmission shaft slides downward relative to the bracket, so that the top of the locking rod loses the support of the bottom plate and rotates in the opposite direction under the action of gravity. After the bottom ends of the locking rods on both sides rotate in opposite directions, the bottom of the mounting port is opened, so that the bracket is smoothly lifted from the overhead line by the drone body, and the automatic disassembly of the operation system is completed, and the operator does not need to perform manual disassembly, which ensures effective support and anti-fall protection for the operator during the entire operation process, greatly reduces the difficulty of disassembly of the operation system and the safety risks during disassembly, and further improves the efficiency of high-altitude live-line operation.

[0031] The present invention will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms fall within the scope limited by the application equally.

[0032] Reference Figure 1 and Figure 3The present invention discloses a live transmission operation system and method based on unmanned aerial vehicle (UAV) and electric lifting technology. The main structure of the operation system includes an unmanned aerial vehicle (UAV) carrying component, an anti-fall protection component, and an insulating rope component which are sequentially arranged from top to bottom. The unmanned aerial vehicle (UAV) carrying component includes an unmanned aerial vehicle (UAV) main body 1 and an insulating rope ladder 2. The unmanned aerial vehicle (UAV) main body 1 can adopt any unmanned aerial vehicle structure that meets the load-bearing requirements and the lifting requirements on the existing market. The insulating rope ladder 2 is a rope ladder structure with an insulating effect in the existing power system. The top of the insulating rope ladder 2 is symmetrically provided with a quick-release connecting ring 3, and the quick-release connecting ring 3 is movably connected to the bottom of the unmanned aerial vehicle (UAV) main body 1. The top of the insulating rope ladder 2 is fixed by bolts or fastened to the quick-release connecting ring 3. At the bottom of the connecting ring 3, the quick-release connecting ring 3 is opened and connected to the bottom of the drone body 1. After the connection, the quick-release connecting ring 3 is closed to realize the rapid disassembly and assembly of the insulating rope ladder 2 and the drone body 1. The anti-fall protection component includes a hanger 4, which is the main load-bearing part of the anti-fall protection component and is generally made of metal. The top of the hanger 4 is vertically slidably connected with a hook 5 used in conjunction with the bottom of the insulating rope ladder 2. The hook 5 is vertically slidably connected to the hanger 4. The hook 5 is hung at the bottom of the insulating rope ladder 2. The hook opening part of the hook 5 extends obliquely downward, so that the hook 5 is not easy to detach from the bottom of the insulating rope ladder 2 after being hung. The bottom of the hook 5 is symmetrically connected through a pin or a hinge The chain is rotatably connected to a transmission arm 6. When the hook 5 slides up and down along the hanger 4, such a structure can drive one end of the two transmission arms 6 to move up and down. The hanger 4 is symmetrically rotatably connected to a swing arm 7 through a pin or a hinge. Specifically, the middle part of the swing arm 7 is rotatably connected to the hanger 4 through a pin or a hinge, and the bottom of the transmission arm 6 is rotatably connected to the top of the swing arm 7 through a pin or a hinge. When the hook 5 slides up and down along the hanger 4, the swing arm 7 can be driven to swing left and right around the rotation position of the middle part under the connection of the transmission arm 6. The lower part of the swing arm 7 is rotatably connected to a limit plate 8, and the limit plate 8 is rotatably connected to the hanger through a pin or a hinge. 4, the limit plate 8 is located below the swing arm 7, and a limit spring 9 is provided between the limit plate 8 and the hanger 4. Specifically, an ordinary spring or a torsion spring can be used, so that the limit plate 8 can compress the limit spring 9 when it rotates toward the limit spring 9, so that it has a tendency to rotate in the opposite direction. One side of the limit plate 8 is provided with a contact end 10 used in conjunction with the bottom of the swing arm 7. When the hook 5 slides upward relative to the hanger 4, such a structure drives the swing arm 7 to rotate under the connection of the transmission arm 6, so that the bottom of the swing arm 7 rotates toward the contact end 10. After the swing arm 7 contacts the contact end 10, the limit plate 8 is driven to rotate toward the limit spring 9 to compress the limit spring 9.

[0033] A limiting end 11 is provided on the other side of the limiting plate 8, and a mounting port 12 for use with the overhead line is provided at the bottom of the mounting bracket 4, and the mounting port 12 is opened downward, so that when the drone body 1 carries the mounting bracket 4 to rise, it first rises to the top of the overhead line, so that the mounting port 12 is aligned with the overhead line below, and then the drone body 1 drives the mounting bracket 4 to descend, so that the mounting port 12 can be stuck downward on the outside of the overhead line, thereby realizing the preliminary cooperation between the mounting bracket 4 and the overhead line. A transmission shaft 13 is vertically slidably connected to the top of the mounting port 12, and the transmission shaft 13 can only slide vertically relative to the mounting bracket 4 without rotating. The bottom of the transmission shaft 13 is fixed with a bottom plate 14 in contact with the overhead line by welding or integral molding. Such a structure The structure makes it possible for the top of the overhead line to contact the bottom plate 14 at the bottom of the transmission shaft 13 after the mounting port 12 is stuck on the overhead line. Since the transmission shaft 13 can slide up and down relative to the bracket 4, as the drone body 1 continues to descend, the transmission shaft 13 maintains the contact state with the overhead line unchanged, and the bracket 4 continues to move downward under the action of gravity, that is, the bracket 4 slides downward relative to the transmission shaft 13, and the corresponding transmission shaft 13 slides upward relative to the bracket 4. The top of the transmission shaft 13 is symmetrically fixed with a limiting step 15 used in conjunction with the limiting end 11 by welding or integral molding. When the transmission shaft 13 slides upward relative to the bracket 4, the limiting step 15 will pass over the limiting end 11 on the limiting plate 8 and slide to the top of the limiting end 11. At this time, The limit plate 8 rotates toward the limit spring 9 under the action of the swing arm 7, driving the limit end 11 to rotate in the direction away from the limit step 15, so that the limit step 15 can smoothly cross the limit end 11, and the two sides of the hanger 4 are symmetrically connected to the locking rod 16 for closing the mounting port 12 through a pin shaft or a hinge. Specifically, the middle part of the locking rod 16 is rotatably connected to the hanger 4 through a pin shaft or a hinge, and the bottom length of the locking rod 16 is greater than the top length, so that the locking rod 16 maintains a vertical state under the action of gravity, and the top end of the locking rod 16 contacts the top of the bottom plate 14. In this structure, when the transmission shaft 13 slides upward relative to the hanger 4, the bottom plate 14 can drive the top end of the locking rod 16 in contact with it to rise, thereby driving the locking rod 16 to rotate When the transmission shaft 13 slides upward, the bottom ends of the locking rods 16 on both sides rotate relatively to close the mounting port 12. Specifically, the bottom end of the locking rod 16 is L-shaped, and the L-shaped corners at the bottom ends of the two locking rods 16 are arranged relatively, so that when the locking rod 16 rotates, the L-shaped corners at the bottom ends of the two locking rods 16 rotate relatively until they contact each other, thereby realizing the closing operation of the bottom of the mounting port 12, so that when the hanger 4 is hung on the overhead line, the transmission shaft 13 slides upward relative to the hanger 4, so that the locking rods 16 on both sides automatically rotate to close the bottom of the mounting port 12, and the overhead line is restricted in the closed mounting port 12, thereby realizing automatic locking with the overhead line. The structure is simple, no manual operation and control are required, and the locking operation of the overhead line is simpler and more secure.After the locking rod 16 closes the bottom of the mounting opening 12, as the drone body 1 continues to descend to the bottom, the insulating rope ladder 2 is separated from the hook 5. At this time, the hook 5 loses the lifting support of the drone body 1 and slides downward relative to the mounting bracket 4 under the action of gravity, and then drives the swing arm 7 to rotate in the opposite direction under the connection of the transmission arm 6, so that the bottom of the swing arm 7 is separated from the contact end 10 on one side of the limit plate 8. Under the action of the limit spring 9, the limit plate 8 rotates in the opposite direction, so that the limit end 11 on the other side of the limit plate 8 rotates toward the limit step 15 and is stuck in the position of the limit step 15, thereby realizing the vertical direction of the transmission shaft 13. The effective restriction makes it impossible for the transmission shaft 13 to slide upward relative to the hanger 4, and indirectly makes the locking rods 16 on both sides of the hanger 4 maintain the closed state of the bottom of the mounting port 12, so that when there is no external force acting on the hook 5, the hanger 4 maintains a stable connection with the overhead line. The entire mounting and locking process does not require manual operation, which greatly simplifies the mounting steps and improves the firmness and convenience of the connection with the overhead line. During subsequent disassembly, the drone body 1 only needs to drive the insulating rope ladder 2 to re-enter the hook 5 to lift it, so as to release the limit end 11 on the transmission shaft 13, so that the transmission shaft 13 can freely move relative to the hook 5. The bracket 4 slides downward, indirectly releasing the locking rod 16 from the closed state of the mounting port 12, so that the bracket 4 can be smoothly lifted upward and separated from the overhead line, and the disassembly process does not require manual control, which improves the fluency and convenience of the entire live working process. A rope installation bolt 17 is provided on one side of the mounting port 12, and the insulating rope assembly includes a lifting rope 18 and a pulling rope 19. The lifting rope 18 is used for the operator to ascend along it using a climbing rope hoist, and the pulling rope 19 is used for the operator on the ground to pull and control the position of the bracket 4 to ensure the stability of the operator's position during high-altitude operations. The lifting rope 18 and the pulling rope 19 are fixed on the rope installation bolt 17. When the hanger 4 is mounted on the overhead line, the lifting rope 18 and the pulling rope 19 are automatically lifted to the working position, and there is no need to build the insulating rope assembly. During the entire construction process, the insulating rope assembly will not directly contact the overhead line, avoiding wear on the surface of the overhead line. Impurities such as metal chips or dust on the overhead line will not enter the interior of the insulating rope assembly and affect its insulation effect, further reducing the impact on the insulation performance of the entire operation system and ensuring the safety of high-altitude live work.

[0034] Preferably, the hanger 4 is provided with a slide groove 20, the bottom of the slide groove 20 is connected to the mounting port 12, and the transmission shaft 13 is vertically slidably connected in the slide groove 20. Specifically, a guide cylinder is provided in the slide groove 20, and the transmission shaft 13 is vertically slidably connected in the guide cylinder, so that the transmission shaft 13 can slide upward from the mounting port 12 to the slide groove 20, thereby ensuring the stability of the up and down sliding structure of the transmission shaft 13 and making the locking control of the locking rods 16 on both sides more secure.

[0035] Preferably, the bottom of the slide groove 20 is connected to a receiving groove 21 used in conjunction with the bottom plate 14, and the bottom plate 14 and the receiving groove 21 are both arc-shaped and used in conjunction with each other. Such a structure allows the drive shaft 13 and the bottom bottom plate 14 to be completely hidden in the slide groove 20 and the receiving groove 21 when the drive shaft 13 slides upward relative to the hanger 4, so that the hanger 4 is directly in contact with the overhead line, so that the drive shaft 13 only serves as a transmission limit function, and does not play a supporting role, thereby ensuring the stability of the limit locking of the lock rod 16 by the drive shaft 13, thereby making the overall operating system and the mounting structure of the overhead line more secure.

[0036] Preferably, the longitudinal section of the limit plate 8 is V-shaped, and the bottom end of the V-shape is rotatably connected to the bracket 4 by a pin shaft or a hinge, and the contact end 10 and the limit end 11 are respectively located at the two ends of the top of the V-shape. Such a structure allows the two ends of the top of the V-shaped structure to be used as the contact end 10 and the limit end 11 respectively, so that when the V-shaped limit plate 8 rotates, the bottom end of the swing arm 7 can rotate from the inside of the V-shape toward the contact end 10 and contact it, thereby accurately driving the limit plate 8 to rotate, and the limit end 11 on the other side of the V-shaped structure can be accurately engaged with the limit step 15, thereby ensuring the firmness of the limit operation of the transmission shaft 13.

[0037] Preferably, the hanger 4 is provided with a guide hole 22, the guide hole 22 passes through the front and rear sides of the hanger 4, the bottom of the hook 5 is slidably connected in the guide hole 22, the hook 5 includes a hook part with an arc-shaped top and a straight rod part extending vertically at the bottom, the straight rod part at the bottom is slidably connected in the guide hole 22, the guide hole 22 provides an accurate and stable guiding restriction for the bottom of the hook 5, and the bottom of the hook 5 is provided with a pin shaft 23, the pin shaft 23 passes through the guide hole 22 and is rotatably connected to the transmission arm 6, specifically, both ends of the pin shaft 23 respectively pass through the front and rear sides of the guide hole 22 and extend to the outside of the guide hole 22, thereby being rotatably connected to the transmission arms 6 on the front and rear sides, so that the hook 5 can accurately drive the transmission arms 6 on both sides to move when sliding up and down, thereby improving the smoothness of the entire transmission structure.

[0038] Preferably, refer to Figure 2The quick-release connecting ring 3 is provided with an arc groove 24, both ends of the arc groove 24 penetrate the quick-release connecting ring 3, a locking ring 25 is rotatably connected in the arc groove 24, the locking ring 25 is an annular structure, a part of the annular structure is rotatably connected in the arc groove 24, a tension spring 26 is provided between the locking ring 25 and the quick-release connecting ring 3, when the locking ring 25 rotates, the tension spring 26 can be stretched to generate a tendency to reset and rotate, the locking ring 25 is provided with an installation opening 27, the opening length of the installation opening 27 is less than the length of the quick-release connecting ring 3, and the installation opening 27 is used to pass through the bottom of the drone body 1 The connection with the drone body 1 is realized at the bottom of the support leg. The quick-release connecting ring 3 is rotatably connected with a limit rod 28 used for matching the two sides of the mounting port 27 through a pin shaft. After the mounting port 27 passes through the support leg at the bottom of the drone body 1, the locking ring 25 is rotated to make the mounting port 27 rotate into the arc groove 24, so that the locking ring 25 and the quick-release connecting ring 3 form a relatively closed structure to ensure the stability of the connection with the drone body 1. At this time, the limiting rod 28 is used to lock the mounting port 27 to ensure the firmness of the connection with the drone body 1, making the entire connection process more efficient and convenient.

In this structure, when the lock ring 25 rotates, the limit rod 28 is first rotated to separate its end from the lock ring 25, and the torsion spring 29 is compressed during this process, so that the lock ring 25 rotates smoothly. When the installation opening 27 on the lock ring 25 smoothly enters the arc groove 24, the limit rod 28 is released, and under the action of the torsion spring 29, the end of the limit rod 28 rotates in the opposite direction to mesh with the limit teeth 30 at the installation opening 27, and maintains the meshing state under the action of the torsion spring 29, thereby realizing automatic locking of the lock ring 25, further simplifying the steps of the connection operation, and improving the efficiency and stability of the connection with the drone body 1.

The setting of the handle 31 facilitates the operator to rotate the locking ring 25 and the limit rod 28. The bottom of the quick-release connecting ring 3 is welded or integrally formed with a rope hole 32 used to cooperate with the top of the insulating rope ladder 2. The top of the insulating rope ladder 2 is tied in the rope hole 32, making the connection and cooperation between the insulating rope ladder 2 and the drone body 1 more efficient and convenient.

[0041] Preferably, refer to Figure 4The rope mounting bolt 17 is sleeved with a plurality of upper fixing rings 33, and the bottom of the upper fixing ring 33 is rotatably connected to a lower fixing ring 34 through a pin shaft. The lower fixing ring 34 can rotate arbitrarily relative to the upper fixing ring 33 in a transverse plane. The lifting rope 18 and the pulling rope 19 are fixed in a plurality of different lower fixing rings 34. Since the rope is easily flipped and twisted during the construction of the insulating rope assembly and the ascent of the operator, the rotation cooperation of the upper fixing ring 33 and the lower fixing ring 34 can effectively avoid the rope curling, thereby ensuring the smoothness of the operator's ascent along the lifting rope 18.

[0042] The live transmission operation method based on drone and electric lifting technology includes the following steps:

[0043] S1. Construction of the operating system. The drone-mounted components, anti-fall protection components, and insulating rope components are connected from top to bottom in sequence. The construction process is completed on the ground, that is, the insulating rope ladder 2 is fixed to the bottom of the drone body 1 using the quick-release connecting ring 3, specifically fixed to the support leg at the bottom of the drone body 1, and then the hook 5 on the pylon 4 is hung on the bottom of the insulating rope ladder 2. Finally, the lifting rope 18 and the pulling rope 19 are fixed to the rope installation bolt 17 at the bottom of the pylon 4, so that the drone-mounted components, anti-fall protection components, and insulating rope components form an operating system, which is convenient for the entire operating system to be lifted together to the operating position of the overhead line when the drone body 1 rises;

[0044] S2, the operation system is lifted off, and the drone body 1 is used to drive the completed operation system to move upward toward the overhead line until the mounting port 12 at the bottom of the mounting bracket 4 is located above the overhead line, and then the drone body 1 stops moving. Specifically, the drone body 1 can move upward along the side of the overhead line, move to a high position on the side, and then move horizontally toward the overhead line, so that the mounting port 12 is accurately located directly above the overhead line;

[0045] S3, mounting of the operating system, the drone body 1 drives the operating system to move downward toward the overhead line, so that the mounting port 12 at the bottom of the mounting bracket 4 is stuck on the overhead line, and the top of the mounting port 12 is arc-shaped, which can contact and cooperate with the overhead line more accurately. During this process, the bottom plate 14 at the bottom of the transmission shaft 13 contacts the overhead line, and the mounting bracket 4 slides downward relative to the transmission shaft 13 under the gravity of the operating system, that is, the transmission shaft 13 slides upward relative to the mounting bracket 4, so that the limiting step 15 at the top of the transmission shaft 13 passes over the limiting plate 8 and is located above the limiting end 11. At the same time, during the upward sliding of the transmission shaft 13 relative to the mounting bracket 4, the bottom plate 14 drives the locking rod 16 in contact with its top to rotate, so that the bottom ends of the locking rods 16 on both sides rotate relative to each other to close the mounting port 12, and then the overhead line is restricted in the closed mounting port 12, and the locking rod 16 can automatically close the mounting port 12 by using the gravity of the mounting bracket 4, without manual operation or remote control, further simplifying the steps of the mounting operation;

[0046] S4, locking of the operating system. When the hanger 4 slides downward relative to the transmission shaft 13 until the top of the mounting port 12 is completely in contact with the overhead line, the entire operating system now completely falls on the overhead line, and the drone body 1 continues to move downward until the insulating rope ladder 2 is separated from the hook 5. Thereafter, the hook 5 loses the support of the drone body 1 and slides downward relative to the hanger 4 under the action of gravity, and drives the swing arm 7 to rotate under the connection of the transmission arm 6, so that the bottom of the swing arm 7 is separated from the contact end 10 on one side of the limit plate 8. Under the action of the limit spring 9, the limit plate 8 rotates toward the transmission shaft 13, so that the limit end 11 on the other side of the limit plate 8 rotates to the limit step 15 of the transmission shaft 13, and the limit end 11 is stuck under the limit step 15, thereby vertically restricting the transmission shaft 13, so that it can no longer slide downward relative to the hanger 4, and then when there is no external force acting on the hook 5, the locking rod 16 keeps the mounting port 12 closed;

[0047] S5. The operator ascends to perform live work. The operator uses a rope climbing hoist to ascend along the lifting rope 18 to the overhead line to perform live work. The ground personnel use the pulling rope 19 to pull and fix the operator's position to ensure the stability of the live work;

[0048] S6, the operator descends and the operating system is disassembled. After the live operation is completed, the operator descends to the ground along the lifting rope 18 under the action of the elevator. After the drone body 1 rises, the insulating rope ladder 2 is hung on the hook 5 again and the hook 5 is pulled upward, so that the hook 5 slides upward relative to the hanger 4. Under the connection of the transmission arm 6, the swing arm 7 is driven to rotate in the opposite direction, so that the bottom of the swing arm 7 contacts the contact end 10 on one side of the limit plate 8 and then drives the limit plate 8 to rotate, thereby making the limit end 11 on the other side of the limit plate 8 disengage from the limit step 15, so that the transmission shaft 13 can automatically slide relative to the hanger 4. When the drone body 1 continues to rise and lifts the hanger 4, the hanger 4 slides upward relative to the transmission shaft 13. That is, the transmission shaft 13 slides downward relative to the bracket 4, so that the top end of the locking rod 16 loses the support of the bottom plate 14 and rotates in the opposite direction under the action of gravity. The bottom ends of the locking rods 16 on both sides rotate away from each other to open the mounting port 12, so that the bracket 4 can be smoothly separated from the overhead line. Thereafter, the drone body 1 drives the operating system to descend to the ground to realize the disassembly of the operating system. The entire disassembly process does not require manual operation or remote control. It is only necessary to use the drone body 1 to lift the hook 5 to successfully disassemble the bracket 4 from the overhead line. The entire process only requires the lifting and lowering control of the drone body 1, which greatly simplifies the operating steps of the entire live operation process and greatly improves the efficiency and convenience of live operation.

[0049] Working principle: The present invention utilizes the drone body 1 to drive the constructed operating system to rise to the overhead line and lock it with the overhead line, so as to achieve effective support and anti-fall protection for the operator's high-altitude operation. The operator does not need to climb the tower in advance to build the operating system, which has higher construction efficiency and safer construction process. There is no restriction on the operating position of the overhead line. The drone body 1 can fly to any position where live-line operation can be carried out, which greatly improves the scope and safety of live-line operation. During the construction of the operating system, the mounting port 1 at the bottom of the bracket 4 is 2 is stuck on the overhead line, the bottom plate 14 at the bottom of the transmission shaft 13 contacts the overhead line, and the bracket 4 slides downward relative to the transmission shaft 13 under the action of gravity, that is, the transmission shaft 13 slides upward relative to the bracket 4. During this process, the limiting step 15 at the top of the transmission shaft 13 passes over the limiting plate 8 and is located above the limiting end 11, and the bottom plate 14 at the bottom of the transmission shaft 13 slides upward to drive the locking rods 16 on both sides to rotate, so that the bottom ends of the locking rods 16 on both sides rotate relative to each other to close the mounting port 12, and the overhead line is restricted in the closed mounting port 12. After the insulating rope ladder 2 at the bottom of the drone body 1 is separated from the hook 5, the hook 5 slides downward relative to the hanger 4 under the action of gravity, and drives the swing arm 7 to rotate under the connection of the transmission arm 6, so that the bottom of the swing arm 7 is separated from the contact end 10 on one side of the limit plate 8. Under the action of the limit spring 9, the limit plate 8 rotates so that the limit end 11 on the other side rotates to the limit step 15, and the cooperation between the limit end 11 and the limit step 15 is used to limit the vertical position of the transmission shaft 13, so as to prevent the transmission shaft 13 from sliding downward relative to the hanger 4, and indirectly make the lock rod 16 keep The mounting opening 12 is kept closed, so that the hanger 4 remains locked with the overhead line when no external force acts on the hook 5, making the connection between the operating system and the overhead line more convenient and firm, and the insulating rope assembly does not directly contact the overhead line during the construction process, reducing the possible wear on the overhead line, and impurities on the overhead line are not easy to enter the insulating rope assembly and affect the insulation effect, thereby providing safe and effective support and anti-fall protection for operators, greatly simplifying the steps of constructing the operating system, and improving the efficiency and safety of the construction;The operator uses the elevator to ascend along the lifting rope 18 to the working position of the overhead line, and returns to the original route after the work is completed. The drone body 1 only needs to hang the insulating rope ladder 2 on the hook 5 again and lift it upward, and then the swing arm 7 can be driven to rotate in the opposite direction under the action of the transmission arm 6, so that the bottom of the swing arm 7 contacts the contact end 10 on one side of the limit plate 8, and then drives the limit plate 8 to rotate, so that the limit end 11 on the other side is separated from the limit step 15, thereby automatically releasing the restriction on the vertical position of the transmission shaft 13. When the bracket 4 continues to be lifted upward, the transmission shaft 13 The relative hanger 4 slides downward, so that the top of the lock rod 16 loses the support of the bottom plate 14 and rotates in the opposite direction under the action of gravity. The bottom ends of the lock rods 16 on both sides rotate in opposite directions to open the bottom of the mounting port 12, so that the hanger 4 can be smoothly lifted from the overhead line by the drone body 1, and the automatic disassembly of the operation system is completed, and the operator does not need to manually disassemble it, which ensures effective support and anti-fall protection for the operator during the entire operation process, greatly reduces the difficulty of disassembly of the operation system and the safety risks during disassembly, and further improves the efficiency of high-altitude live-line operations. ;
