Abstract
Description
Technical Field
[0001] This invention relates to the field of power grounding wire hanging and removing technology, and in particular to a method for hanging and removing grounding wires. Background Technology
[0002] Currently, grounding wires must be installed before maintenance work is carried out on power outage lines or equipment. This is to prevent induced voltage from injuring people and to effectively avoid personal injury to maintenance personnel caused by accidental power restoration.
[0003] Traditional grounding wire installation work typically involves workers carrying the grounding wire up the tower, working layer by layer and phase by phase, and then dismantling it sequentially after completion. This traditional method is physically demanding and carries risks such as injury from induced voltage and falls from heights. With the widespread use of drones and robots in power transmission line maintenance, combining drones with grounding wire installation technology can effectively improve maintenance efficiency and ensure operational safety.
[0004] Existing drone-based grounding wire installation technologies and methods are basically the same: the low-voltage side grounding clamp is fixed to the tower leg, the high-voltage side grounding clamp is mounted on the drone and clamped to the conductor, and the grounding wire is lifted to the conductor end using an insulated rope and connected to the grounding clamp. After the operation is completed, the removal sequence is the reverse of the installation. However, the higher the conductor and tower, the longer the required grounding wire, resulting in a heavier grounding wire and making it more difficult to lift. In addition, the low-voltage end is attached to the tower leg, making it easy for non-operating personnel to accidentally untie or steal it, posing a significant risk of electric shock.

[0035] The present invention will be further described in detail below with reference to the accompanying drawings.
[0036] Reference Figures 1 to 3 The present invention discloses a method for attaching and removing grounding wires, which includes the following steps: S101, a drone equipped with a pole end grounding wire attachment and removal device 1 attaches the pole end grounding wire attachment and removal device 1 to the angle steel 3 at the crossarm position of the pole end to be attached; thereby saving manpower and improving the safety of the operation.
[0037] Continue to refer to Figures 2 to 6 In this embodiment, the pole end grounding wire hanging and unhanging device 1 includes a pole end traction rope 10 and a pole end connecting mechanism 20. One end of the pole end traction rope 10 is set on the ground, and the other end of the pole end traction rope 10 is connected to the pole end connecting mechanism 20.
[0038] Specifically, one end of the pole-end traction rope 10 can be manually pulled by the staff. Of course, one end of the pole-end traction rope 10 can also be connected to a reel device set on the ground.
[0039] It should be noted that the winding device is an existing device, and its structure will not be described in detail here.
[0040] Continue to refer to Figure 2 and Figure 3 In this embodiment, the pole end grounding wire hanging and unhanging device 1 also includes a pole end grounding wire clamp 30, the bottom end of which is connected to the pole end connecting mechanism 20.
[0041] Furthermore, in this embodiment, the tower end grounding clamp 30 includes a tower end lifting ring 31 and a rotating clamp 32. The tower end lifting ring 31 is connected to the rotating clamp 32 through a connector 33. The rotating clamp 32 can rotate relative to the connector 33. The bottom end of the connector 33 is connected to the tower end connecting mechanism 20. The tower end lifting ring 31 is used to hang on the UAV. By setting the rotating clamp 32, it is convenient to surround the angle steel 3 at the position of the tower end crossarm to be hung from multiple sides, thereby improving the firmness of the connection between the tower end grounding clamp 30 and the angle steel 3.
[0042] For example, the tower end lifting ring 31 can be U-shaped; of course, the tower end lifting ring 31 can also be circular. In the U-shaped implementation of the tower end lifting ring 31, the open end of the tower end lifting ring 31 is connected to the top end of the connector 33 so that the tower end lifting ring 31 is in a closed state.
[0043] Specifically, the connector 33 is a rectangular frame with an opening, so as to... Figure 2 Taking the orientation shown as an example, the left side of the bottom end of the connector 33 is connected to the tower end connection mechanism 20, and the right side of the bottom end of the connector 33 is connected to the rotating clamp 32 through a rotating shaft. The rotating clamp 32 can rotate relative to the connector 33.
[0044] For example, the rotating clamp 32 can be U-shaped; of course, the rotating clamp 32 can also be C-shaped. In the earlier implementation where the rotating clamp 32 is U-shaped, when the tower end lifting ring 31 is mounted on the UAV, the concave opening of the rotating clamp 32 faces downwards under its own weight; when the connecting piece 33 is placed on the angle steel 3, the concave opening of the rotating clamp 32 faces the angle steel 3, and the end of the rotating clamp 32 located inside the connecting piece 33 contacts the top surface of the angle steel 3, so as to... Figure 2 Taking the orientation shown as an example, under the gravity of the connector 33 and the tower end lifting ring 31, the rotating clamp 32 is pushed to rotate clockwise, so as to form a multi-faceted enclosure of the angle steel 3.
[0045] Continue to refer to Figures 4 to 6 In this embodiment, the tower end connection mechanism 20 includes a tower end locking assembly 21 and a tower end ground wire connection terminal 22. The first end of the tower end traction rope 10 is disposed on the ground, and the second end of the tower end traction rope 10 is slidably inserted into the tower end locking assembly 21 and connected to the tower end ground wire connection terminal 22.
[0046] Specifically, with Figure 2 Taking the orientation shown as an example, the top of the tower end locking assembly 21 is connected to the left side of the bottom end of the connector 33.
[0047] The tower end locking assembly 21 includes a lifting unit 211, a housing 212, and two locking units 213. The top end of the lifting unit 211 is connected to the bottom end of the connector 33, and the bottom end of the lifting unit 211 is connected to the housing 212. The housing 212 forms a rotating cavity 2121. One end of the tower end ground wire connection terminal 22 can be inserted into the rotating cavity 2121. The two locking units 213 are arranged opposite to each other on opposite sides of the housing 212. One end of each locking unit 213 is inserted into the rotating cavity 2121. Both locking units 213 can slide left and right relative to the housing 212. The two locking units 213 cooperate to lock the tower end ground wire connection terminal 22 after it is inserted into the rotating cavity 2121.
[0048] Specifically, one end of the traction rope 10 at the tower end can slide through the lifting unit 211 and simultaneously pass through the rotating cavity 2121 and the tower end ground wire connection terminal 22.
[0049] The lifting unit 211 includes two lifting plates 2111 arranged opposite to each other and at least one fixed pulley 2112. Both lifting plates 2111 are connected to the bottom end of the connector 33. The fixed pulley 2112 is rotatably arranged between the two lifting plates 2111. One end of the tower end traction rope 10 is wound around the fixed pulley 2112 and then passes through the rotating cavity 2121 and the tower end ground wire connection terminal 22.
[0050] The top of the housing 212 has a through hole 2122 for the tower end traction rope 10 to pass through. The through hole 2122 extends along the center line of the rotating cavity 2121 and is connected to the rotating cavity 2121. During use, one end of the tower end traction rope 10 is wound around the fixed pulley 2112 and then passes through the through hole 2122 and is inserted into the rotating cavity 2121 and the tower end ground wire connection terminal 22.
[0051] In order to facilitate the sliding of the tower end ground wire connection terminal 22 along the rotating cavity 2121, the bottom end of the housing 212 is provided with a sliding hole 2123 that communicates with the rotating cavity 2121.
[0052] It should be noted that the size of the sliding hole 2123 should ensure that the ground wire connection terminal 22 at the tower end can slide freely.
[0053] The bottom of the housing 212 can be truncated cone-shaped, or it can be trapezoidal, as long as the tower end ground wire connection terminal 22 is smoothly inserted into the housing 212.
[0054] During use, the pole end traction rope 10 is used to pull the pole end ground wire connection terminal 22 to move.
[0055] To prevent the tower end ground wire connection terminal 22 from tipping over during sliding within the rotating cavity 2121, a limiting sleeve 214 is provided within the rotating cavity 2121. The outer peripheral wall of the limiting sleeve 214 contacts the inner peripheral wall of the rotating cavity 2121. The cavity of the limiting sleeve 214 is adapted to the top shape of the tower end ground wire connection terminal 22. In the feasible implementation where the top of the tower end ground wire connection terminal 22 is conical, the cavity of the limiting sleeve 214 is inverted conical. When the tower end ground wire connection terminal 22 is inserted into the rotating cavity 2121, the limiting sleeve 214 is used to fit over the top of the tower end ground wire connection terminal 22. The limiting sleeve 214 can slide along the rotating cavity 2121 simultaneously with the tower end ground wire terminal.
[0056] The outer peripheral wall of the limiting sleeve 214 is provided with a first mounting hole and a second mounting hole on opposite sides. The center line of the first mounting hole and the center line of the second mounting hole are arranged parallel to each other. In some feasible ways, the center line of the first mounting hole and the center line of the second mounting hole are collinear. The center line of the first mounting hole is perpendicular to the center line of the rotating cavity 2121.
[0057] Furthermore, in this embodiment, a first boss 215 and a second boss 217 are provided on the outer wall near the top of the housing 212. The first boss 215 and the second boss 217 are disposed opposite to each other on opposite sides of the housing 212. The first boss 215 is disposed corresponding to the first mounting hole, and the second boss 217 is disposed corresponding to the second mounting hole.
[0058] A first notch 2124 and a second notch 2125 are provided on the outer wall near the top of the housing 212. The first notch 2124 and the second notch 2125 are arranged opposite to each other. It should be noted that the first notch 2124 is located above the first boss 215, and the second notch 2125 is located above the second boss 217. Both the first notch 2124 and the second notch 2125 extend along the center line of the limiting sleeve 214, and both the first notch 2124 and the second notch 2125 are connected to the rotating cavity 2121.
[0059] The first boss 215 is provided with a limiting shaft 2151. The center line of the limiting shaft 2151 is parallel to the center line of the rotating cavity 2121. The limiting shaft 2151 is rotatably connected to the first boss 215 via a rotating rod 2152. A wave-shaped limiting groove 2153 is provided on the outer peripheral wall of the limiting shaft 2151. A limiting rod 216 is inserted into the wave-shaped limiting groove 2153. The end of the limiting rod 216 facing away from the limiting shaft 2151 passes through the first notch 2124 and is inserted into the first mounting hole. When the limiting sleeve 214 slides up or down along the rotating cavity 2121, the limiting sleeve 214 drives the limiting rod 216 to move up or down. The limiting rod 216 slides along the wave-shaped limiting groove 2153 to drive the limiting shaft 2151 to rotate.
[0060] When the limiting rod 216 slides to the low position in the wave-shaped limiting groove, it restricts the limiting rod 216 from moving upward and at the same time restricts the limiting sleeve 214 connected to it, further restricting the tower end ground wire connection terminal from moving upward.
[0061] Furthermore, in this embodiment, a guide plate 2171 is provided on the second boss 217. The guide plate 2171 is perpendicular to the second boss 217. A guide groove is provided on the guide plate 2171. The guide groove extends along the center line of the limiting sleeve 214. The guide groove is correspondingly provided with the second notch 2125. A guide rod 218 is inserted in the guide groove. One end of the guide rod 218 away from the guide groove passes through the second notch 2125 and is inserted into the second mounting hole. The guide rod 218 can slide along the guide groove and the second notch 2125.
[0062] The rotating cavity 2121 is equipped with a helical spring 219. The center line of the helical spring 219 is collinear with the center line of the limiting sleeve. The top end of the helical spring 219 is connected to the top end of the rotating cavity 2121, and the bottom end of the helical spring 219 is connected to the top end of the limiting sleeve.
[0063] It should be noted that the inner diameter of the helical spring 219 is larger than the diameter of the through hole 2122.
[0064] During use, pulling the first end of the tower end traction rope 10 causes the tower end ground wire terminal to slide upward along the rotating cavity 2121. The top end of the tower end ground wire connection terminal 22 is inserted into the limiting sleeve 214, causing the limiting sleeve 214 to slide upward. The limiting sleeve 214 applies upward pressure to the helical spring 219, which is then compressed. The tower end ground wire terminal, through the limiting sleeve 214, causes the limiting rod 216 and guide rod 218 to slide upward simultaneously. The end of the limiting rod 216 away from the limiting sleeve 214 pushes the limiting shaft 2151 to rotate, so that the limiting rod 216 slides along the wave-shaped limiting... The positioning groove 2153 slides, and the guide rod 218 slides along the guide groove at one end away from the limiting sleeve 214. When the limiting rod 216 slides to the highest position of the wave-shaped limiting groove 2153, the tower end ground wire connection terminal 22 stops sliding. At this time, the helical spring 219 is at its maximum compression. Then, the first end of the tower end traction rope 10 is released. At this time, the tower end ground wire connection terminal 22 moves rapidly downward under its own weight and the restoring force of the helical spring 219. Under the action of the impact force and its own weight, the tower end ground wire connection terminal 22 slides out of the limiting sleeve 214 and then slides out of the rotating cavity 2121. At this time, the tower end ground wire connection terminal 22 is in the unlocked state.
[0065] Furthermore, in this embodiment, the tower end ground wire connection terminal 22 includes a ground wire hook 221, a counterweight 222, and an unlocking ring 223. The top of the ground wire hook 221 has a wire-passing hole, which extends along the center line of the ground wire hook 221 and passes through the ground wire hook 221. An internal thread is provided on the inner peripheral wall near the bottom end of the wire-passing hole.
[0066] Specifically, a through hole is provided at the top of the hammer 222. The through hole extends along the center line of the hammer 222 and passes through the hammer 222. An external thread is provided on the outer peripheral wall near the top of the hammer 222. The internal thread is adapted to the external thread. The top of the hammer 222 is inserted into the wire hole. The hammer 222 is threadedly connected to the ground wire hook 221. The through hole is connected to the wire hole. One end of the pole end traction rope 10 is wound around the fixed pulley 2112 and then passes through the through hole 2122 and is inserted into the rotating cavity 2121, the wire hole and the through hole.
[0067] The unlocking ring 223 is fitted onto the ground wire hook 221, and the unlocking ring 223 can slide along the ground wire hook 221.
[0068] Furthermore, in this embodiment, the grounding hook 221 includes a first cylindrical portion 2212, a second cylindrical portion 2213, and a frustum portion 2214. The diameter of the first cylindrical portion 2212 is smaller than the diameter of the second cylindrical portion 2213. The diameter of the larger diameter end of the frustum portion 2214 is the same as the diameter of the second cylindrical portion 2213. The larger diameter end of the frustum portion 2214 is connected to the top end of the second cylindrical portion 2213. The end of the second cylinder away from the frustum portion 2214 is connected to the top end of the first cylindrical portion 2212. That is, the grounding hook 221 is in the shape of an upward arrow.
[0069] The second cylindrical portion 2213 has a groove 2215 at one end opposite to the frustum portion 2214.
[0070] Furthermore, in this embodiment, the unlocking ring is shaped like an inverted frustum, and the diameter of the larger diameter end of the unlocking ring is the same as the diameter of the second cylindrical portion 2213. The larger diameter end of the unlocking ring is provided with a flange 2231 that is adapted to the groove 2215. During the unlocking process, the flange 2231 is inserted into the groove 2215, and the larger diameter end of the unlocking ring 223 abuts against the end of the second cylindrical portion 2213 that is away from the frustum portion 2214.
[0071] Furthermore, in this embodiment, the counterweight 222 includes a first cylinder 2222, a second cylinder 2223, and a third cylinder 2224. The diameter of the first cylinder 2222 is smaller than the diameter of the second cylinder 2223, the diameter of the second cylinder 2223 is smaller than the diameter of the third cylinder 2224, and the diameter of the third cylinder 2224 is larger than the diameter of the small-diameter end of the unlocking ring 223. The bottom end of the first cylinder 2222 is connected to the top end of the third cylinder 2224, and the bottom end of the third cylinder 2224 is connected to the top end of the second cylinder 2223.
[0072] In the initial state, the small-diameter end of the unlocking tube is in contact with the top surface of the third cylinder 2224.
[0073] During use, when the ground wire hook 221 is pulled by the traction rope 10 at the tower end, the frustum 2214 of the ground wire hook 221 passes through the sliding hole 2123 and enters the rotating cavity 2121. Two locking units lock the first cylindrical part 2212 of the ground wire hook 221 to prevent the ground wire hook 221 from detaching from the housing 212.
[0074] Each locking unit has one end inserted into the rotating cavity 2121. The housing 212 has a socket for each locking unit. The socket extends radially along the rotating cavity 2121 and communicates with the rotating cavity 2121.
[0075] Furthermore, in this embodiment, the locking unit 213 includes a lock body 2131, a locking pin 2132, and an elastic element 2133; wherein, the lock body 2131 is disposed outside the housing 212, and the lock body 2131 has an inwardly extending locking groove on the side facing the insertion hole; the elastic element 2133 is disposed in the locking groove, the first end of the locking pin 2132 is slidably inserted into the locking groove and connected to the elastic element 2133, the second end of the locking pin 2132 passes through the insertion hole and is inserted into the rotating cavity 2121, and the second end of the locking pin 2132 is used to abut against the first cylindrical portion 2212 in the ground wire hook 221.
[0076] In the initial state, the distance between the second ends of the two locking pins 2132 can be equal to the diameter of the first cylindrical part 2212 in the ground wire hook 221; the elastic element 2133 is in the normal state, and the second ends of the two locking pins 2132 are inserted into the rotating cavity 2121 after passing through the corresponding insertion hole.
[0077] When the ground wire hook 221 is inserted into the rotating cavity 2121, the ground wire hook 221 squeezes the two locking pins 2132, causing the two elastic elements 2133 to be in a compressed state. After the frustum portion 2214 in the ground wire hook 221 passes through the two locking pins 2132, under the action of the elastic restoring force of the two elastic elements 2133, the two locking pins 2132 move towards the first cylindrical portion 2212 in the ground wire hook 221 until the two locking pins 2132 abut against the outer peripheral wall of the first cylindrical portion 2212. At this time, the two second elastic elements 2133 are in the initial state, and the bottom end of the second cylindrical portion 2213 is blocked by the two locking pins 2132, preventing the tower end ground wire connection terminal 22 from sliding out of the sliding hole 2123, thus realizing the locking of the tower end ground wire connection terminal 22.
[0078] When the tower end ground wire connection terminal 22 is in the locked state, the ground wire hook 221 is inserted into the rotating cavity 2121, and the small diameter end of the frustum 2214 in the ground wire hook 221 is inserted into the limiting sleeve 214. At this time, the end of the limiting rod 216 away from the limiting sleeve 214 is located at the lowest position of the wave-shaped limiting groove 2153. The two locking pins 2132 abut against the outer peripheral wall of the first cylindrical part 2212. At this time, the two elastic elements 2133 are in a compressed state. Under the action of the restoring force of the two elastic elements 2133, the two locking pins 2132 abut against the first cylindrical part 2212. At the same time, the bottom end of the second cylindrical part 2213 is blocked by the two locking pins 2132, which can effectively prevent the ground wire hook 221 from sliding out of the sliding hole 2123, thus realizing the locking of the tower end ground wire connection terminal 22.
[0079] Further, in this embodiment, S101, the drone equipped with the pole end grounding wire hanging and dismantling device 1 hangs the pole end grounding wire hanging and dismantling device 1 on the angle steel 3 at the position of the pole end crossarm, including: the pole end grounding wire clamp 30 is mounted on the drone, the drone drives the pole end grounding wire hanging and dismantling device 1 to the position of the pole end crossarm to be hung, and the pole end grounding wire clamp 30 is hung on the angle steel 3 at the position of the pole end crossarm to be hung.
[0080] The tower end grounding clamp 30 is mounted on a drone. The drone drives the tower end grounding wire hanging and dismantling device 1 to the position of the crossarm to be hung on the tower end. The tower end grounding clamp 30 is hung on the angle steel 3 at the position of the crossarm to be hung on the tower end. The process includes: the tower end lifting ring 31 is mounted on the drone. The drone drives the tower end grounding wire hanging and dismantling device 1 to the position of the crossarm to be hung on the tower end. The connecting piece 33 is placed on the angle steel 3. One end of the rotating clamp 32 contacts the top surface of the angle steel 3. Under the action of the gravity of the connecting piece 33, the rotating clamp 32 is pushed to rotate so that the angle steel 3 is surrounded.
[0081] Specifically, the pole end lifting ring 31 is mounted on the drone. Under its own weight, the concave opening of the rotating clamp 32 faces downward. The drone drives the pole end grounding wire attachment / removal device 1 to the position of the pole end crossarm to be attached. The drone controls the connection piece 33 to be placed on the angle steel 3. The concave opening of the rotating clamp 32 is directly opposite the angle steel 3, and the end of the rotating clamp 32 located inside the connection piece 33 is in contact with the top surface of the angle steel 3. Under the weight of the connection piece 33 and the pole end lifting ring 31, the rotating clamp 32 is pushed to rotate clockwise to form a multi-faceted enclosure of the angle steel 3.
[0082] S102. The drone equipped with the conductor end grounding device 2 attaches the conductor end grounding device 2 to one of the sub-conductors 4 of the transmission line to be connected; thereby saving manpower and improving the safety of the operation.
[0083] Continue to refer to Figures 7 to 9 In this embodiment, the conductor end grounding wire hanging and unhanging device 2 includes a conductor end traction rope 201 and a conductor end connecting mechanism 202. One end of the conductor end traction rope 201 is set on the ground, and the other end of the conductor end traction rope 201 is connected to the conductor end connecting mechanism 202.
[0084] Specifically, one end of the conductor end traction rope 201 can be manually pulled by the staff. Of course, one end of the conductor end traction rope 201 can also be connected to the winding device set on the ground.
[0085] Furthermore, in this embodiment, the conductor end grounding wire hanging and unhanging device 2 also includes a conductor end grounding wire clamp 203, the bottom end of which is connected to the conductor end connecting mechanism 202.
[0086] The conductor end grounding clamp 203 includes a hooking component 2031 and a clamping component 2035, which are slidably connected. The bottom end of the clamping component 2035 is connected to the conductor end connecting mechanism 202. The hooking component 2031 is used to hang on the UAV. The UAV drives the conductor end hooking and unhooking grounding device 2 to move to the transmission line to be connected through the hooking component 2031. The clamping component 2035 is used to hang on one of the sub-conductors 4 of the transmission line to be connected.
[0087] Specifically, the hook assembly 2031 includes a wire end ring 2032 and a stop bar 2033. The top end of the stop bar 2033 is connected to the outer peripheral wall of the wire end ring 2032, and the bottom end of the stop bar 2033 passes through the clamping assembly 2035. The stop bar 2033 can slide relative to the clamping assembly 2035.
[0088] To prevent the stop lever 2033 from sliding out of the clamping assembly 2035, a limit block 2034 is provided at the bottom of the stop lever 2033, and the extension direction of the limit block 2034 is perpendicular to the center line of the stop lever 2033.
[0089] Furthermore, in this embodiment, the clamping assembly 2035 includes two mounting plates 2036 arranged opposite to each other, a fixing block 2037, and a clamping unit. The first ends of the two mounting plates 2036 are both arc-shaped to facilitate hanging on the sub-wire 4. The fixing block 2037 is disposed between the first ends of the two mounting plates 2036. A through hole is opened at the top of the fixing block 2037, and a stop bar 2033 passes through the through hole. The stop bar 2033 can slide along the through hole.
[0090] The clamping unit is located between the second ends of the two mounting plates 2036. The bottom end of the clamping unit is connected to the top end of the wire end connecting mechanism 202. The clamping unit and the two mounting plates 2036 work together to clamp the sub-wire 4.
[0091] Furthermore, in this embodiment, the clamping unit includes a connecting spring, a connecting rod 2038, and an arc-shaped clamping rod 2039, the first end of the connecting rod 2038 ( Figure 8 The upper end shown) and the first end of the arc-shaped clamp 2039 ( Figure 8 The right end shown is rotatably connected to the second end of the arc-shaped clamp 2039. Figure 8 The left end shown is the free end. The arc-shaped part of the arc-shaped clamp 2039 is adapted to the guide. The second end of the arc-shaped clamp 2039 cooperates with the two mounting plates 2036 to clamp the sub-wire 4. The second end of the connecting rod 2038 ( Figure 8 The lower end shown is connected to the top end of the wire end connection mechanism 202.
[0092] Specifically, the bottom end of the connecting spring is connected to the connection point of the connecting rod 2038 and the arc-shaped clamping rod 2039, and the top end of the connecting spring is connected to the two mounting plates 2036 through the suspension rod, which is located between the two mounting plates 2036.
[0093] During use, after the conductor end connection mechanism 202 is connected and locked to the grounding wire 5, under the combined gravity of the conductor end connection mechanism 202 and the grounding wire 5, the connecting rod 2038 moves downward and drives the first end of the arc-shaped clamping rod 2039 to move downward. At this time, the connecting spring is in a stretched state, and the movement of the arc-shaped clamping rod 2039 is restricted by the two mounting plates 2036. Using the lever principle, the second end of the arc-shaped clamping rod 2039 rotates upward so that the second end of the arc-shaped clamping rod 2039 cooperates with the two mounting plates 2036 to clamp the sub-conductor 4.
[0094] It should be noted that the arc-shaped clamp 2039 can rotate between 0° and 90°.
[0095] To further improve the firmness of the connection between the two mounting plates 2036 and the sub-wire 4, a downwardly extending fixing plate 2042 is provided at the second end of each of the two mounting plates 2036. A U-shaped retaining ring 2043 is provided on the fixing plate 2042. The two sides of the open end of the retaining ring 2043 are respectively connected to the two fixing plates 2042. The retaining ring 2043 is correspondingly set to the through hole, that is, the retaining ring 2043 is located below the through hole. The stop rod 2033 and the limiting block 2034 are slidably inserted into the retaining ring 2043.
[0096] Specifically, the retaining ring 2043 is spaced at a preset distance from the through hole.
[0097] Furthermore, in this embodiment, the wire end connection mechanism 202 includes a wire end locking component 2021 and a wire end ground wire connection terminal 2022. The first end of the wire end traction rope 201 is disposed on the ground, and the second end of the wire end traction rope 201 is slidably inserted into the wire end locking component 2021 and connected to the wire end ground wire connection terminal 2022.
[0098] It should be noted that the structure of the conductor end locking assembly 2021 is basically the same as that of the tower end locking assembly 21, and the structure of the conductor end ground wire connection terminal 2022 is basically the same as that of the tower end ground wire connection terminal 22. Therefore, the structures of the conductor end locking assembly 2021 and the conductor end ground wire connection terminal 2022 will not be described in detail here.
[0099] Further, in this embodiment, S102, the drone equipped with the conductor end grounding device 2 attaches the conductor end grounding device 2 to one of the sub-conductors 4 of the transmission line to be connected, including: the conductor end grounding clamp 203 is mounted on the drone, the drone drives the conductor end grounding device 2 to the position of the transmission line to be connected, and the conductor end grounding clamp 203 is attached to one of the sub-conductors 4 of the transmission line to be connected.
[0100] The conductor end grounding clamp 203 is mounted on a drone. The drone drives the conductor end grounding device 2 to the location of the transmission line to be connected. The conductor end grounding clamp 203 is hung on one of the sub-conductors 4 of the transmission line to be connected. The process includes: the hooking component 2031 is mounted on the drone. The drone drives the conductor end grounding device 2 to the location of the transmission line to be connected and hangs the hooking component 2035 on the sub-conductor 4.
[0101] Specifically, the conductor end shackle 2032 is mounted on the drone, and the stop bar 2033 and the retaining ring 2043 are in a separated state, that is, the stop bar 2033 is in an open state. The drone drives the conductor end grounding wire attachment and removal device 2 to the position of the transmission line to be attached, and controls the drone to hang the two mounting plates 2036 on the sub-conductor 4. The stop bar 2033 slides down into the retaining ring 2043 under its own gravity, that is, the stop bar 2033 is locked.
[0102] Continue to refer to Figure 10 In this embodiment, in step S103, the first end of the grounding wire 5 is connected to the tower end connection mechanism 20, and the second end of the grounding wire 5 is connected to the conductor end connection mechanism 202. The tower end traction rope 10 is pulled to raise the first end of the grounding wire 5 to conduct through the angle steel 3. The conductor end traction rope 201 is pulled to raise the second end of the grounding wire 5 to conduct through the sub-conductor 4, so that the conductor end and the tower end are connected through the grounding wire 5. Compared with the prior art where the grounding wire 5 is fixed to the tower leg for a long time, this avoids the risk of accidental disconnection and theft, and improves security.
[0103] Furthermore, in this embodiment, connecting the first end of the grounding wire 5 to the tower end connection mechanism 20 includes: pulling the first end of the tower end traction rope 10, unlocking the tower end ground wire connection terminal 22, and the tower end ground wire connection terminal 22 sliding down to the ground under the action of the counterweight in the tower end traction rope 10 and the tower end ground wire connection terminal 22, and connecting the first end of the grounding wire 5 to the tower end ground wire connection terminal 22.
[0104] Specifically, the unlocking process of the tower end ground wire connection terminal 22 is as follows: Pulling the first end of the tower end traction rope 10 causes the tower end traction rope 10 to drive the tower end ground wire connection terminal 22 to slide upward along the rotating cavity 2121. At this time, the counterweight 222 and the unlocking ring 223 both move upward. The frustum 2214 in the ground wire hook 221 pushes the limiting sleeve 214 upward. The limiting sleeve 214 drives the limiting rod 216 and the guide rod 218 upward. The end of the limiting rod 216 away from the limiting sleeve 214 pushes the limiting shaft 2151 to rotate, so that the limiting rod 216 slides along the wave-shaped limiting groove 2153. When the end of the limiting rod 216 away from the limiting sleeve 214 is at the highest position of the wave-shaped limiting groove 2153... At this time, the tower end ground wire connection terminal 22 stops moving. At this time, the helical spring 219 is in the maximum compression state. The flange 2231 in the unlocking ring 223 is inserted into the groove 2215. The large diameter end of the unlocking ring 223 contacts the bottom end of the second cylindrical part 2213 in the ground wire hook 221 and forms a whole. The outer peripheral wall of the large diameter end of the unlocking ring 223 abuts against the ends of the two locking pins 2132. Under the action of the impact force and its own gravity, the tower end ground wire connection terminal 22 separates from the limiting sleeve 214. The ground wire hook 221 can be released from the locking of the two locking pins 2132 along with the unlocking ring 223 and continue to move downward to get away from the housing 212. The tower end ground wire connection terminal 22 descends to the ground under the action of the tower end traction rope 10.
[0105] The first end of the grounding wire 5 is connected to the counterweight 222 in the tower end grounding wire connection terminal 22 that is lowered to the ground.
[0106] Furthermore, in this embodiment, connecting the second end of the grounding wire 5 to the conductor end connection mechanism 202 includes: pulling the first end of the conductor end traction rope 201, unlocking the conductor end ground wire connection terminal 2022, and the conductor end ground wire connection terminal 2022 sliding down to the ground under the action of the weight in the conductor end traction rope 201 and the conductor end ground wire connection terminal 2022, and connecting the second end of the grounding wire 5 to the conductor end ground wire connection terminal 2022.
[0107] It should be noted that the unlocking process of the conductor end ground wire connection terminal 2022 is basically the same as the unlocking process of the tower end ground wire connection terminal 22, so the unlocking process of the conductor end ground wire connection terminal 2022 will not be described in detail here.
[0108] The second end of the grounding wire 5 is connected to the counterweight 222 in the grounding wire connection terminal 2022 of the conductor that is lowered to the ground.
[0109] Furthermore, in this embodiment, pulling the tower end traction rope 10 to raise the first end of the grounding wire 5 to be connected to the angle steel 3 includes: pulling the first end of the tower end traction rope 10 to raise the first end of the grounding wire 5 to the tower end ground wire connection terminal 22 to the tower end ground wire connection terminal 22 and the tower end locking assembly 21 for locking connection.
[0110] Specifically, the locking process of the tower end ground wire connection terminal 22 is as follows: Pull the second end of the tower end traction rope 10, and the tower end ground wire connection terminal 22 and the first end of the ground wire 5 are lifted upward under the action of the tower end traction rope 10 until the ground wire hook 221 in the tower end ground wire connection terminal 22 is inserted into the rotating cavity 2121, and the frustum part 2214 in the ground wire hook 221 is inserted into the limiting sleeve 214. The end of the limiting rod 216 away from the limiting sleeve 214 is located at the lowest position of the wave-shaped limiting groove 2153. At the same time, the ends of the two locking pins 2132 are in contact with the outer peripheral wall of the first cylindrical part 2212 of the ground wire hook 221. At this time, the first end of the ground wire 5 is connected to the angle steel 3 at the position of the tower end crossarm through the tower end ground wire connection terminal 22.
[0111] Furthermore, in this embodiment, pulling the conductor end traction rope 201 to raise the second end of the grounding wire 5 to conduct electricity with the sub-conductor 4 includes: pulling the first end of the conductor end traction rope 201 to raise the second end of the grounding wire 5 to the conductor end ground wire connection terminal 2022 until the conductor end ground wire connection terminal 2022 is locked and connected to the conductor end locking assembly 2021.
[0112] It should be noted that the locking process of the conductor end ground wire connection terminal 2022 is basically the same as the locking process of the tower end ground wire connection terminal 22, so the locking process of the conductor end ground wire connection terminal 2022 will not be described in detail here.
[0113] After the ground wire connection terminal 2022 is locked, under the combined gravity of the ground wire 5 and the wire end connection mechanism 202, the connecting rod 2038 in the clamping assembly 2035 moves downward, and the connecting rod 2038 drives the first end of the arc-shaped clamping rod 2039 ( Figure 8 The right end shown in the diagram moves downwards. At this time, the connecting spring is in a stretched state, and the movement of the arc-shaped clamp 2039 is restricted by the two mounting plates 2036. Utilizing the lever principle, the second end of the arc-shaped clamp 2039 ( Figure 8 The left end shown in the diagram is rotated upwards so that the second end of the arc-shaped clamp 2039 engages with the two mounting plates 2036 to clamp the sub-wire 4.
[0114] S104. After the operation is completed, disconnect the tower end from the conductor end.
[0115] S104. After the operation is completed, disconnect the tower end from the conductor end, including:
[0116] S1041. After the operation is completed, pull the first end of the conductor end traction rope 201. The conductor end ground wire connection terminal 2022 is unlocked. The conductor end ground wire connection terminal 2022 and the second end of the ground wire 5 slide down to the ground under the action of the conductor end traction rope 201, disconnecting the conductor end ground wire connection terminal 2022 from the second end of the ground wire 5.
[0117] S1042. Pull the first end of the tower end traction rope 10, the tower end ground wire connection terminal 22 is unlocked, and the tower end ground wire connection terminal 22 and the first end of the grounding wire 5 slide down to the ground under the action of the tower end traction rope 10, disconnecting the tower end ground wire connection terminal 22 and the first end of the grounding wire 5.
[0118] S1043. After removing grounding wire 5, use a drone to remove the pole end grounding wire removal device 1 and the conductor end grounding wire removal device 2 in sequence.
[0119] Specifically, after removing the grounding wire 5, the pole end lifting ring 31 is hung on the drone. The drone pulls the pole end lifting ring 31 upwards. At this time, the bottom end of the rotating clamp 32 contacts the ground with the angle iron 3, and the drone gradually pulls the pole end lifting ring 31 upwards. Figure 3 Taking the indicated orientation as an example, the rotating clamp 32 rotates counterclockwise under the action of the pulling force until the concave opening of the rotating clamp 32 faces downward. The drone is then controlled to separate the pole end grounding wire clamp 30 from the angle steel 3. The drone then drives the entire pole end grounding wire hanging and dismantling device 1 to the ground, and the pole end grounding wire hanging and dismantling device 1 is dismantled.
[0120] After the pole-end grounding wire removal device 1 is removed, the conductor end lifting ring 2032 is hung on the drone. The drone slowly lifts the conductor end lifting ring 2032 upward. At this time, the stop bar 2033 and the stop ring 2043 are separated, that is, the stop bar 2033 is in the open state. Control the drone to separate the clamping unit from the sub-conductor 4. The drone drives the conductor end grounding wire removal device 2 to move to the ground as a whole. The disassembly of the conductor end grounding wire removal device 2 is completed.
[0121] The grounding wire hanging and removing method provided in this application includes the following steps: a drone equipped with a tower end grounding wire hanging and removing device 1 hangs the tower end grounding wire hanging and removing device 1 on the angle steel 3 at the crossarm position of the tower end to be hung; a drone equipped with a conductor end grounding wire hanging and removing device 2 hangs the conductor end grounding wire hanging and removing device 2 on one of the sub-conductors 4 of the transmission line to be hung; the tower end grounding wire hanging and removing device 1 includes a tower end traction rope 10 and a tower end connection mechanism 20, one end of the tower end traction rope 10 is set on the ground, and the other end of the tower end traction rope 10 is connected to the tower end connection mechanism 20; the conductor end grounding wire hanging and removing device 2 includes a conductor end traction rope 201 and a conductor end connection mechanism 202, one end of the conductor end traction rope 201 is set on the ground, and the other end of the conductor end traction rope 201 is connected to the conductor end connection mechanism 202. The grounding wire 5 is connected to the tower end connection mechanism 202. The first end of the grounding wire 5 is connected to the tower end connection mechanism 20, and the second end of the grounding wire 5 is connected to the conductor end connection mechanism 202. The tower end traction rope 10 is pulled to raise the first end of the grounding wire 5 to conduct through the angle steel 3. The conductor end traction rope 201 is pulled to raise the second end of the grounding wire 5 to conduct through the sub-conductor 4, so that the conductor end and the tower end are connected through the grounding wire 5. After the operation is completed, the tower end and the sub-conductor 4 end are disconnected. By pulling the tower end traction rope 10 and the conductor end traction rope 201, the tower end is connected through the grounding wire 5 to the conductor end, saving manpower. In addition, compared with the existing technology where the grounding wire 5 is fixed to the tower leg for a long time, it avoids the risk of accidental disconnection and theft, solves the problem that the grounding wire needs to be as long as the tower is high, and improves safety.
