DETAILED DESCRIPTION

[0038] In order to make the technical problems solved by the present application, the technical solutions adopted and the technical effects achieved more clear, the technical solutions of the embodiments of the present application will be further described in detail below with reference to the drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0039] In the present application, unless otherwise explicitly specified and limited, the first feature is "on" or "under" the second feature can include that the first and second features are in direct contact, or can include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, the first feature "on", "above" and "over" the second feature includes that the first feature is directly above and obliquely above the second feature, or only indicates that the first feature is horizontally higher than the second feature. The first feature "under", "below" and "underneath" the second feature includes that the first feature is directly below and obliquely below the second feature, or only indicates that the first feature is horizontally lower than the second feature.

[0040] As shown in Figures 1 to 9 The lifting device for power maintenance of the present application includes a hanging mechanism 1, a winch mechanism 2, a maintenance frame 3 or a traction rope 4. The hanging mechanism 1 includes a hanging piece 11 and a pressing piece 12. The hanging piece 11 is provided with a hanging groove 111 on one side for hanging the power transmission conductor 100. The pressing piece 12 is movably arranged on the side of the hanging piece 11 away from the hanging groove 111. The winch mechanism 2 is located below the hanging mechanism 1. The maintenance frame 3 is connected with the winch mechanism 2 and is used for standing or arranging maintenance equipment. The non-end part of the traction rope 4 is hung on the side of the hanging piece 11 away from the hanging groove 111. The traction rope 4 can control the pressing piece 12 to selectively press the traction rope 4 on the hanging piece 11. Both ends of the traction rope 4 are connected with the winch mechanism 2. The winch mechanism 2 is used for winding or unwinding the traction rope 4 to move at a constant speed along the traction direction of the traction rope 4, thereby driving the maintenance frame 3 to rise or fall.

[0041] The lifting device for power maintenance of the present embodiment can reduce the wear of the power transmission conductor 100 in the maintenance process by buckling the hanging groove 111 of the hanging piece 11 into the power transmission conductor 100 and hanging the traction rope 4 on the hanging piece 11, so that the traction rope 4 is not directly hung on the power transmission conductor 100. Both ends of the traction rope 4 extend downward and are connected with the winch mechanism 2. Then the winch mechanism 2 is used for winding or unwinding the traction rope 4 to move at a constant speed along the traction direction of the traction rope 4, thereby driving the maintenance frame 3 to rise or fall, so that the maintenance personnel standing on the maintenance frame 3 or the maintenance equipment placed thereon can rise or fall at a constant speed, improving the safety of maintenance. In addition, when disassembling, the traction rope 4 can be first disassembled from the winch mechanism 2. The traction rope 4 controls the pressing piece 12 to press the traction rope 4 on the hanging piece 11. Then the traction rope 4 is directly pulled downward. The traction rope 4 drives the hanging piece 11 to rotate a certain angle along the power transmission conductor 100 and then separates from the power transmission conductor 100 and is hung on the traction rope 4. With the traction rope 4 being pulled slowly, the traction rope 4 slowly falls to the ground, thereby completing the disassembly of the hanging piece 11 on the power transmission conductor 100, without the need for maintenance personnel to climb high, which is convenient for disassembly and reduces the risk coefficient of maintenance operation.

[0042] Specifically, the maintenance rack 3 comprises a bearing plate and a fence arranged around the periphery of the bearing plate, the fence is arranged on the bearing plate to form a maintenance space, and the maintenance personnel can stand in the maintenance space or place the maintenance equipment in the maintenance space.

[0043] Specifically, as shown in Figure 5 and Figure 6 , the hoisting mechanism 2 comprises a rack 21, and a rope winding assembly 22 and a rope climbing assembly 23 arranged on the rack 21, both ends of the traction rope 4 are connected with the rope climbing assembly 23 and the rope winding assembly 22 respectively, the rope winding assembly 22 is used for winding or unwinding the traction rope 4, the rope climbing assembly 23 is engaged with the traction rope 4 to drive the hoisting mechanism 2 to move uniformly in the traction direction of the traction rope 4, the rope winding assembly 22 is configured to detect the tension of the traction rope 4 located between the rope climbing assembly 23 and the rope winding assembly 22, and the rope winding assembly 22 can adjust the winding or unwinding speed according to the size of the tension. The rope climbing assembly 23 is engaged with the traction rope 4 to move back and forth in the traction direction of the traction rope 4, and since the rope climbing assembly 23 is arranged on the rack 21, the entire hoisting mechanism 2 can move in the traction direction of the traction rope 4, the rope winding assembly 22 can detect the tension of the traction rope 4 located between the rope climbing assembly 23 and the rope winding assembly 22, and the rope winding assembly 22 adjusts the winding or unwinding speed according to the size of the tension, so that the winding or unwinding speed of the hoisting mechanism 2 is equal to the climbing speed, so that the rope winding assembly 22 can orderly wind the traction rope 4, and the rope climbing assembly 23 is not used for winding the traction rope 4, and during the winding of the traction rope 4 by the hoisting mechanism 2, the winding speed of the traction rope 4 will not change due to the number of winding turns, so that the hoisting mechanism 2 can move uniformly in the traction direction.

[0044] It should be noted that the traction direction is the pulling direction of the traction rope 4 on the hoisting mechanism 2, and in this embodiment, the traction direction is the vertical direction. When the hoisting mechanism 2 is only provided with the rope winding assembly 22, since the pulling force of the traction rope 4 is constant, the tension of the traction rope 4 will not change, and the detection mechanism cannot adjust the winding or unwinding speed by detecting the tension.

[0045] Preferably, the maintenance rack 3 is detachably connected with the rack 21, so as to facilitate the production and manufacturing of the device. The detachable connection between the maintenance rack 3 and the rack 21 can be achieved by threaded connection, buckling, clamping or other detachable connection methods, which is not limited to the embodiment.

[0046] Specifically, as shown in Figure 7As shown, the rope climbing assembly 23 comprises a mounting panel 234, a second driving member 231 arranged in the mounting space, and a rope climbing member 232 arranged on the side of the mounting panel 234 away from the second driving member 231. The mounting panel 234 is detachably arranged on one side of the rack 21. The mounting panel 234 is provided with an avoiding hole. The second driving member 231 is connected with the rope climbing member 232 through the avoiding hole. The rope climbing member 232 is provided with a clamping portion 2321 for clamping the traction rope 4. The second driving member 231 drives the rope climbing member 232 to rotate at a constant speed, so that the clamping portion 2321 can clamp the traction rope 4 to drive the rope climbing assembly 23 to move. Since the rope climbing assembly 23 is arranged on the rack 21, the whole winding mechanism moves at a constant speed along the traction direction of the traction rope 4. During the clamping of the traction rope 4 by the clamping portion 2321, no relative sliding occurs between the clamping portion 2321 and the traction rope 4. The rotation of the clamping portion 2321 can realize the movement of the rope climbing assembly 23 along the traction direction, thereby driving the whole winding mechanism 2 to move upward. It can be understood that the movement of the winding mechanism 2 mainly depends on the clamping of the traction rope 4 by the rope climbing member 232, and the traction rope 4 is not wound on the rope climbing member 232 in turns. Therefore, as long as the rotation speed of the rope climbing member 232 is constant, the rope climbing member 232 will not be affected by the winding turns, so that the winding mechanism 2 can drive the maintenance rack 3 to move at a constant speed. Finally, the traction rope 4 is wound on the winding member 222 by the rotation of the winding member 222. During the winding of the winding member 222, the winding member 222 is affected by the winding turns. The length of the traction rope 4 wound or unwound by the winding member 222 per rotation is different, so that the winding speed of the winding member 222 changes. However, the rope climbing speed of the rope climbing member 232 is constant. In order to solve the above technical problem, the detection member is further introduced in the embodiment. The tension of the traction rope 4 between the rope climbing member 232 and the winding member 222 is detected by the detection member, so as to adjust the output power of the first driving member 221, thereby changing the rotation speed of the winding member 222, so as to adapt the winding or unwinding speed of the winding mechanism 2 to the rope climbing speed of the rope climbing member 232, thereby solving the problems of the constant speed of the maintenance rack 3 and the orderly winding of the winding member 222.

[0047] For example, the second driving member 231 drives the rope climbing member 232 to rotate forward, and the rope climbing assembly 23 moves upward. At the same time, the rope climbing member 232 can transmit part of the traction rope 4 to the winding member 222, so as to wind the traction rope 4 by the winding member 222. When the second driving member 231 drives the rope climbing member 232 to rotate reversely, the rope climbing assembly 23 moves downward, and the winding member 222 unwinds the traction rope 4.

[0048] In the embodiment, the detection member is arranged on the mounting panel 234. Figures 5 to 8As shown, the hoisting mechanism 2 and the traction rope 4 are both provided with two, two traction ropes 4 are arranged on the hanging piece 11 in an interval, and two traction ropes 4 are connected with one hoisting mechanism 2 respectively, the maintenance rack 3 is located between two hoisting mechanisms 2, and the maintenance rack 3 is connected with two hoisting mechanisms 2 respectively. The maintenance rack 3 is connected through two hoisting mechanisms 2, on the one hand, it can provide larger driving force for the maintenance rack 3, so that the maintenance rack 3 can place heavier weights, to adapt to more maintenance scenes; on the other hand, the relative two sides of the maintenance piece are connected with two maintenance racks 3 respectively, which can improve the stability of the lifting of the maintenance rack 3.

[0049] The lifting device for power maintenance of the embodiment can be applied to the double split transmission line 100, and the double split transmission line 100 is provided with two transmission lines 100 in an interval along the vertical direction, the hanging piece 11 is hung on the transmission line 100 located above, when the hanging mechanism 1 is hung on the transmission line 100, the transmission line 100 located above will be pressed downward by the gravity of the hanging mechanism 1 and the hoisting mechanism 2, which will cause the transmission line 100 to locally fall. However, in order to prevent the two transmission lines 100 from being in contact and difficult to be manually separated, a sufficient gap needs to be left between the two transmission lines 100 to facilitate manual separation of the hanging equipment with tools, so a separation structure needs to be used to separate the two transmission lines 100. Specifically, as shown in the figure, Figure 2 As shown, the hanging mechanism 1 further includes a line separation frame 13, the line separation frame 13 is connected with the hanging piece 11 through the traction rope 4, the line separation frame 13 is located between the two transmission lines 100, and the line separation frame 13 is used to separate the transmission line 100 located above and the transmission line 100 located below, when the transmission line 100 falls, the transmission line 100 located above abuts against the upper side of the line separation frame 13, and the transmission line 100 located below abuts against the lower side of the line separation frame 13, so that the two transmission lines 100 cannot be directly combined and closely attached.

[0050] In the embodiment, as shown in the figure, Figure 6As shown, the rope collecting assembly 22 comprises a first driving member 221, a detection member (not shown in the drawings) and a rope collecting member 222, the first driving member 221 is arranged on the rack 21, the detection member is signal connected with the first driving member 221, the detection member is used for detecting the tension, the first driving member 221 is connected with the rope collecting member 222, part of the traction rope 4 is wound on the rope collecting member 222, and the first driving member 221 can drive the rope collecting member 222 to rotate to collect or release the traction rope 4. In the use process, the detection member can send a signal to the first driving member 221 according to the size of the detected tension to control the speed of the first driving member 221 driving the rope collecting member 222 to rotate, so as to ensure that the collecting or releasing speed of the rope collecting member 222 matches the climbing speed of the rope climbing assembly 23, which helps the rope arranging member 223 to orderly collect the traction rope 4 on the rope collecting sleeve, prevents the traction rope 4 from being loosely and disorderly wound, and causes a safety hazard. Through the design, the maintenance rack 3 can be uniformly lifted, and the rope collecting assembly 22 can orderly collect the rope.

[0051] Specifically, the first driving member 221 comprises a first motor 2211, a first transmission gear 2212, a second transmission gear 2213 and a first rotating shaft, the first motor 2211 is signal connected with the detection member, an output shaft of the first motor 2211 is connected with the first transmission gear 2212, the second transmission gear 2213 is engaged with the first transmission gear 2212, the second transmission gear 2213 is connected with the rope collecting member 222 through the first rotating shaft, and the rope collecting member 222 rotates coaxially with the first rotating shaft. The output shaft of the first motor 2211 drives the first transmission gear 2212 to rotate, the first transmission gear 2212 is engaged with the second transmission gear 2213 to drive the second transmission gear 2213 to rotate, the second transmission gear 2213 drives the first rotating shaft to rotate, thereby driving the rope collecting member 222 to rotate, so that the rope collecting assembly 22 orderly collects or releases the traction rope 4, and drives the entire winch mechanism 2 to move in the vertical direction, thereby driving the maintenance rack 3 to ascend or descend.

[0052] Specifically, the first transmission gear 2212 and the second transmission gear 2213 are both conical gears, therefore, when the first transmission gear 2212 and the second transmission gear 2213 are engaged, the central axis of the first transmission gear 2212 and the central axis of the second transmission gear 2213 are arranged vertically, which can reduce the occupied space of the first transmission gear 2212 and the second transmission gear 2213, and make the structure of the rope collecting assembly 22 more compact.

[0053] Preferably, the detection element is a permanent magnet synchronous controller, which can detect the magnitude of the torque of the output shaft of the first motor 2211. When the tension of the traction rope 4 is large, the torque of the output shaft of the first motor 2211 is large. When the tension of the traction rope 4 decreases, the torque of the output shaft of the first motor 2211 decreases. Therefore, the torque of the output shaft of the first motor 2211 matches the tension of the traction rope 4. Therefore, the permanent magnet synchronous controller can detect the magnitude of the tension of the traction rope 4 by detecting the magnitude of the torque. It should be noted that the control principle of the permanent magnet synchronous controller is as follows: when it is detected that the torque of the output shaft of the first motor 2211 is large, the permanent magnet synchronous controller reduces the current of the first motor 2211, thereby reducing the speed of the output shaft of the first motor 2211; if it is detected that the torque of the output shaft of the first motor 2211 is small, the permanent magnet synchronous controller increases the current of the first motor 2211, thereby increasing the speed of the output shaft of the first motor 2211.

[0054] Specifically, the rope collecting member 222 includes a rope loop 2221 and rope winding drums spaced apart on either side of the rope loop 2221. A rope collecting groove is formed between the two rope winding drums. The rope loop 2221 is connected to the first driving member 221. A portion of the traction rope 4 is wound around the rope loop 2221 and located within the rope collecting groove. The groove wall of the rope collecting groove can limit the traction rope 4 wound around the rope loop 2221 to prevent the traction rope 4 from loosening. In this embodiment, a first rotating shaft is inserted into the rope loop 2221. The first rotating shaft rotates to drive the rope loop 2221 to rotate. The first driving member 221 is disposed on the side of the rope collecting drum 2222 facing away from the rope groove.

[0055] In one embodiment, Figure 6 As shown, the rope collecting assembly 22 also includes a rope arranging member 223, which is arranged on the frame 21 and is located on one side of the rope collecting member 222. The rope arranging member 223 is connected to the first driving member 221, and the traction rope 4 located between the rope collecting member 222 and the rope climbing assembly 23 is connected to the rope arranging member 223. The first driving member 221 is connected to the rope arranging member 223, and the first driving member 221 drives the rope arranging member 223 to move to change the position of the traction rope 4 entering the rope collecting member 222, so that the traction rope 4 is orderly gathered on the rope winding loop 2221, and the traction rope 4 is regularly arranged in the rope winding groove. It can be understood that the rope loop 2221 has a certain length. If the position where the traction rope 4 enters the rope winding groove remains unchanged, when the rope taking-up member 222 reels the traction rope 4, the traction rope 4 is wound on the same position of the rope loop 2221, so that the number of winding turns of the traction rope 4 at this position of the rope loop 2221 increases rapidly, so that the detection member needs to increase the number of times to adjust the rotation speed of the first motor 2211 to adapt to the rope taking-up speed, thereby increasing the loss of the winding mechanism; in addition, by winding and pulling the traction rope 4 at only one position on the traction rope 4, the winding radius of the traction rope 4 is increased, which easily exceeds the groove wall of the rope winding groove and slides out of the limit of the rope winding groove.

[0056] Specifically, as shown in Figure 6 and Figure 9 The rope arranging member 223 includes a lead screw 2231, a rope arranging block 2232, and a reversing pin 2234. The lead screw 2231 is connected with the first driving member 221, and the rotation axis of the lead screw 2231 is arranged in parallel with the rotation axis of the rope collecting member 222. The rope arranging block 2232 is provided with a reversing hole 22321, a plug-in hole 22324, and a rope arranging hole 22322 at intervals. The plug-in hole 22324 is connected in vertical communication with the reversing hole 22321. The rope arranging hole 22322 is arranged in vertical communication with the reversing hole 22321 and the plug-in hole 22324. The lead screw 2231 is arranged in the reversing hole 22321. The lead screw 2231 is respectively provided with a first helical groove and a second helical groove with opposite rotation directions. The reversing pin 2234 is arranged in the plug-in hole 22324 and extends to the reversing hole 22321 to cooperate with the first helical groove or the second helical groove. The traction rope 4 is arranged in the rope arranging hole 22322. The first driving member 221 drives the rotation of the lead screw 2231. Under the cooperation of the reversing pin 2234 and the thread of the helical groove, the lead screw 2231 can drive the reversing pin 2234 to reciprocate along the length direction of the lead screw 2231. Since the reversing pin 2234 is arranged on the rope arranging block 2232, the movement of the reversing pin 2234 drives the rope arranging block 2232 to move along the length direction of the lead screw 2231. When the reversing pin 2234 moves to the limit position, the reversing pin 2234 can enter the other helical groove (from the first helical groove to the second helical groove, or from the second helical groove to the first helical groove), so that the rope arranging block 2232 can move in the opposite direction to realize the function of the reciprocating movement of the lead screw 2231 driving the rope arranging block 2232. The rope arranging block 2232 can drive the traction rope 4 to enter the rope collecting member 222 at different positions, so that the traction rope 4 can be wound on the rope winding sleeve 2221 at different positions. It can be understood that when the rope arranging block 2232 moves to the limit position with the lead screw 2231, the rope arranging block 2232 changes the moving direction under the action of the reversing pin 2234 to move back, thereby realizing the reciprocating movement to guide the traction rope 4 to be collected or released in the rope arranging groove in an orderly manner. In the embodiment, the end of the reversing pin 2234 is in an arc shape. The annular reversing pin 2234 can be adapted to the helical groove.

[0057] Further, a bolt is arranged at one end of the reversing pin 2234 and is threadedly connected with the plug-in hole 22324 to limit the reversing pin 2234, so that the end of the reversing pin 2234 is in sliding fit with the helical groove on the lead screw 2231.

[0058] Preferably, the rope arranging member 223 further comprises a guide rod 2233 which is parallel to the lead screw 2231 and is arranged on the frame 21 in a spaced manner, and the rope arranging member 223 is provided with a first guide hole 22323, and the guide rod 2233 is arranged in the first guide hole 22323. On the one hand, the guide rod 2233 is used to guide the rope arranging block 2232 to move in a specified direction; on the other hand, the guide rod 2233 cooperates with the lead screw 2231 to increase the movement stability of the rope arranging block 2232.

[0059] Specifically, as shown in Figure 9 the rope arranging block 2232 is a cuboid which comprises a first side surface and a second side surface connected at an included angle, the first side surface faces the rope collecting member 222, the rope arranging hole 22322 penetrates through the first side surface, and the first guide hole 22323 and the reversing hole 22321 penetrate through the second side surface. Preferably, the rope arranging hole 22322 is a trumpet hole, and the cross-sectional area of the opening of the rope arranging hole 22322 gradually decreases towards the middle position.

[0060] Preferably, the first driving member 221 further comprises a first transmission member, and the first motor 2211 is connected with the lead screw 2231 through the first transmission member, so that the rope collecting member 222 and the rope arranging member 223 can share one first motor 2211, thereby reducing the manufacturing cost of the rope collecting assembly 22. During use, the detecting member can change the rotating speed of the rope collecting member 222 and the moving speed of the rope arranging block 2232 at the same time by controlling the rotating speed of the first motor 2211.

[0061] In the embodiment, as shown in Figure 6 the first transmission member comprises a fifth transmission wheel 2214, a sixth transmission wheel 2215 and a transmission belt 2216, the fifth transmission wheel 2214 is arranged on the first rotating shaft, the sixth transmission wheel 2215 is connected with the lead screw 2231, the transmission belt 2216 is annular, and the two ends of the transmission belt 2216 are sleeved on the fifth transmission wheel 2214 and the sixth transmission wheel 2215. The first motor 2211 drives the first rotating shaft to rotate, so as to drive the fifth transmission wheel 2214 to rotate coaxially, the fifth transmission wheel 2214 drives the sixth transmission wheel 2215 to rotate through the transmission belt 2216, thereby driving the lead screw 2231 to rotate. It should be noted that the feeding amount of the rope arranging block 2232 driven by one rotation of the rope collecting groove is the diameter of the traction rope 4 wound by the rope collecting groove, so as to ensure the tightness of the rope collecting groove and avoid the disordered winding of the traction rope 4.

[0062] Optionally, a rope clamping member is arranged on the rope collecting disc 2222, and after the one end of the traction rope 4 is wound on the rope winding sleeve 2221, the traction rope 4 is fixed on the rope clamping member, so as to prevent the traction rope 4 from being loosened from the rope collecting member 222.

[0063] Another embodiment is different from the above-mentioned embodiments in that the structure of the first driving member 221 is different. In this embodiment, the first transmission member is not provided, and two first motors 2211 can be independently provided. One first motor 2211 is connected with the first rotating shaft to drive the rope collecting member 222, and the other first motor 2211 is connected with the screw rod 2231 to drive the rope arranging member 223.

[0064] In this embodiment, as shown in Figure 8 The engagement portion 2321 is a climbing rope groove provided on the sidewall of the climbing rope member 232. The sidewall of the climbing rope groove is provided with engagement teeth 23211, which abut against the traction rope 4. The traction rope 4 is wound on the groove bottom of the climbing rope groove in a half-winding manner, and the part of the traction rope 4 inside the climbing rope groove is abutted by the engagement teeth 23211.

[0065] Specifically, the climbing rope member 232 includes two oppositely arranged climbing rope discs 2322. The climbing rope disc 2322 includes a main body 23221, and a boss 23222 is provided on one side of the main body 23221. The bosses 23222 of the two climbing rope discs 2322 abut against each other, so that the sidewalls of the two bosses 23222 form the groove bottom of the climbing rope groove, and the sidewalls of the two main bodies 23221 form the sidewalls of the climbing rope groove. The boss 23222 is a cylinder, and the engagement teeth 23211 are annularly and uniformly distributed on the sidewall of the main body 23221 around the central axis of the boss 23222.

[0066] Specifically, as shown in Figure 7 The wheel cover 235 is provided on the side of the mounting panel 234 where the climbing rope member 232 is arranged. The wheel cover 235 is provided with a receiving groove, and the climbing rope member 232 is arranged in the receiving groove to be protected by the wheel cover 235.

[0067] Specifically, the climbing rope assembly 23 further includes a rope guide member 233. The rope guide member 233 includes a guide block 2331 and limiting blocks 2332 which are arranged at two sides of the guide block 2331. The guide block 2331 has oppositely arranged first and second guide surfaces 23311 and 23312. The first guide surface 23311 and one of the limiting blocks 2332 form an entry port, and the second guide surface 23312 and the other limiting block 2332 form an exit port. One end of the traction rope 4 enters the climbing rope groove from the entry port and extends out of the exit port to be connected to the rope collecting assembly 22. By arranging the rope guide member 233 on one side of the climbing rope member 232, and limiting the entry port and the exit port between the guide block 2331 and the two limiting blocks 2332, the traction rope 4 can enter the climbing rope groove from the entry port, wind around the outer periphery of the boss 23222, and then extend to the rope collecting member 222 from the exit port. In this embodiment, the limiting member and the guide member are arranged on the mounting panel 234.

[0068] Optionally, at least part of the guide member is located in the rope winding groove to add a second guide surface 23312 to guide the traction rope 4 to extend out of the rope winding groove and connect with the rope collecting member 222, wherein the guide member is spaced from the bottom of the rope winding groove to prevent the guide member from interfering with the rope climbing member 232.

[0069] Preferably, a first roller is rotatably provided on the limiting block 2332 , and when the traction rope 4 is rollingly connected to the first roller, the friction between the traction rope 4 and the limiting member is reduced, thereby reducing the wear of the traction rope 4 .

[0070] Preferably, the first guide surface 23311 and the second guide surface 23312 are set at an acute angle, and a clamping gap is formed between the first guide surface 23311 and the second guide surface 23312 facing the boss 23222. This design helps the guide block 2331 guide the traction rope 4 to enter or exit the rope winding groove.

[0071] Optionally, a second roller 24 is rotatably provided on the frame 21, and the second roller 24 is located on one side of the rope climbing member 232. The traction rope 4 located between the rope climbing member 232 and the rope collecting member 222 abuts against the second roller 24 to prevent the traction rope 4 from directly abutting against the crossbeam of the frame 21, so as to reduce the wear of the traction rope 4.

[0072] Preferably, if Figure 7 As shown, the second driving member 231 includes a second motor 2311, a third transmission gear 2312, two fourth transmission gears 2313, and a second rotating shaft 2314. The third transmission gear 2312 is connected to the output shaft of the second motor 2311. Two fourth transmission gears 2313 are provided, and both are connected to the third transmission gear 2312. Each fourth transmission gear 2313 is connected to a second rotating shaft 2314. The rope climbing member 232 is connected to the second rotating shaft 2314. In this design, the two rope climbing members 232 share a second motor 2311 to reduce the number of motors used, thereby reducing manufacturing costs. Sharing a second motor 2311 can ensure that the two rope climbing members 232 rotate synchronously, thereby improving the stability of the movement of the hoisting mechanism 2. During operation, the second motor 2311 drives the third transmission gear 2312 to rotate. The third transmission gear 2312 meshes with the fourth transmission gear 2313 to drive the fourth transmission gear 2313 to rotate. The fourth transmission gear 2313 drives the second rotating shaft 2314 to rotate. The second rotating shaft 2314 drives the two rope climbing members 232 to rotate at the same speed and in opposite directions. The same speed can maintain balance during the ascent or descent process, and the opposite rotation direction makes the two rope entry points farther apart, increasing the stability of the rope climbing. Among them, a gear plate 2315 is provided on the side of the mounting panel 234 facing away from the rope climbing member 232. The third transmission gear 2312 and the third transmission gear 2313 are both disposed within the gear plate 2315.

[0073] In this embodiment, two third transmission gears 2312 are provided, one of the third transmission gears 2312 is connected with the output shaft of the second motor 2311, and the two third transmission gears 2312 are respectively engaged with two fourth transmission gears 2313 to reduce the wear of a single third transmission gear 2312, thereby prolonging the service life of the third transmission gear 2312.

[0074] Optionally, a guide ring is arranged on the rack 21, and the traction rope 4 is first arranged in the guide ring before being connected with the rope climbing assembly 23, so as to limit and guide the traction rope 4.

[0075] In one embodiment, as shown in Figure 2 and Figure 3 The side of the hanging line piece 11 away from the hanging line groove 111 is an arc-shaped surface, and at least one first rope passing groove 112 is arranged on the arc-shaped surface. The length of the first rope passing groove 112 extends along the curvature of the arc-shaped surface, and the two ends of the first rope passing groove 112 arranged along the length direction are both provided with a rope passing port. The pressing piece 12 is rotationally arranged at the groove port of the first rope passing groove 112, and the traction rope 4 can act on one end of the pressing piece 12 to drive the other end of the pressing piece 12 to rotate, so as to tightly press the traction rope 4 in the first rope passing groove 112. The back surface of the hanging line piece 11 is provided with an arc-shaped surface, which has no edges or corners, so as to facilitate the disassembly of the traction rope 4 on the hanging line piece 11, and the first rope passing groove 112 arranged on the hanging line piece 11 can limit the traction rope 4 and prevent the traction rope 4 from sliding along the length direction of the hanging line piece 11. After the maintenance work is completed, the winch mechanism 2 and the maintenance rack 3 are first lowered to the ground, then the two ends of the traction rope 4 are removed from the winch mechanism 2, then the traction rope 4 at one end is tilted at a certain angle with the vertical direction, so that the traction rope 4 can act on one end of the pressing piece 12 to drive the other end of the pressing piece 12 to rotate, so as to tightly press the traction rope 4 in the first rope passing groove 112, then the traction rope 4 is continuously pulled downward, because the pressing block presses the traction rope 4, the traction rope 4 drives the hanging line piece 11 to rotate along the power transmission conductor 100, until the hanging line piece 11 is separated from the power transmission conductor 100, then the hanging line piece 11 can fall off the power transmission conductor 100, without the need for manual climbing to disassemble the hanging line piece 11, which is simple in operation and high in maintenance efficiency, and reduces the risk coefficient of the maintenance personnel.

[0076] Preferably, the cross section of the hanging line piece 11 is in a U-shaped structure.

[0077] It should be noted that in order to ensure that the hoisting mechanism 2 can keep stable during lifting, the traction rope 4 needs to have flexibility on the hanging line 11, and the traction rope 4 and the hanging line 11 are usually not locked to adjust the height of the two rope climbing members 232 to avoid the inclination of the hoisting mechanism 2, thereby causing the inclination of the maintenance rack 3. Therefore, after the maintenance is completed, the hanging line 11 cannot be directly pulled down by the lifting rope. However, the present embodiment ingeniously sets the pressing member 12, so that the maintenance personnel can control the traction rope 4 to detach the hanging line 11 from the power transmission conductor 100.

[0078] Specifically, as shown in Figure 4 The pressing member 12 includes a pressing block 121 and a hinge shaft 122, and the non-end portion of the pressing block 121 is hinged to the slot wall of the first rope passing slot 112 through the hinge shaft 122, so that the pressing block 121 is rotationally arranged at the slot opening of the first rope passing slot 112 to form a rope passing cavity, and the traction rope 4 is arranged in the rope passing cavity. This design can prevent the traction rope 4 from accidentally detaching, and the traction rope 4 can drive the pressing block 121 to rotate along the central axis of the hinge shaft 122, so that the other end of the pressing block 121 abuts against the slot bottom of the first rope passing slot 112. At this time, when the bottom continuously collects the rope, the traction rope 4, the pressing member 12 and the hanging line 11 move together to gradually detach the entire hanging line mechanism 1 from the power transmission conductor 100.

[0079] In an embodiment, a torsional spring (not shown in the figure) is arranged on the hinge shaft 122, wherein one end of the torsional spring is connected to the slot wall of the first rope passing slot 112, and the torsional spring has a reset function. When the maintenance personnel normally work, the torsional spring provides a torsional force for the pressing block 121, so that the pressing block 121 does not abut against the traction rope 4 at both ends, so as to facilitate the adjustment of the two ends of the traction rope 4. When it is necessary to detach the hanging line mechanism 1, the traction rope 4 drives the pressing block 121 to rotate to offset the torsional force, so as to abut against the traction rope 4 to detach the hanging line mechanism 1, and when the detachment is completed, the torsional spring resets the pressing block 121.

[0080] In an embodiment, the distribution rack 13 is provided with a second guide hole 1321 corresponding to each traction rope 4, and one side of the traction rope 4 is movably arranged in the second guide hole 1321 to guide the upward and downward adjustment movement of the traction rope 4, thereby avoiding the left and right shaking of the traction rope 4.

[0081] Specifically, as shown in Figure 3 The distribution rack 13 includes a first distribution plate 131 and a second distribution plate 132 connected at an included angle, and the second distribution plate 132 is arranged on the side surface of the first distribution plate 131 away from the hanging line 11. A guide ring is arranged on the side surface of the second distribution plate 132, and the inner wall of the guide ring forms a guide hole. Preferably, the first distribution plate 131 and the second distribution plate 132 are formed by bending one plate.

[0082] Specifically, the first contact gap 1311 is arranged on the first branch line plate 131, and the first contact gap 1311 is arranged on both sides of the first branch line plate 131 and spaced from the guide ring, so that the traction rope 4 on both sides of the power transmission conductor 100 is arranged on the guide hole and the first contact gap 1311, respectively. Optionally, the first contact gap 1311 is arranged at the corner position of the first branch line plate 131.

[0083] Specifically, in order to improve the safety of maintenance, the wire hanging device further comprises a safety rope 5, and in the embodiment, the connecting member is the safety rope 5, one end of the safety rope 5 is connected with the branch line frame 13, and the other end extends to the lower side of the power transmission conductor 100 through the wire hanging member 11, so as to be connected with the maintenance personnel or the maintenance equipment. When an emergency occurs, the safety rope 5 can play a protective role to prevent the maintenance personnel from falling directly to the ground. In the embodiment, the second branch line plate 132 is provided with a fixing ring 1322, and the wire hanging member 11 is provided with a second rope passing groove 161, one end of the safety rope 5 is connected with the fixing ring 1322, the other end is arranged in the second rope passing groove 161, and extends to the lower side of the power transmission conductor 100.

[0084] Optionally, the first branch line plate 131 is provided with a second contact gap 1312, and the safety rope 5 is clamped in the second contact gap 1312, so as to limit the safety rope 5 from sliding randomly.

[0085] When the lifting equipment fails or the maintenance personnel accidentally falls, the safety rope 5 pulls the branch line frame 13 upward, and the branch line frame 13 can be abutted against the groove of the wire hanging groove 111, so as to prevent the maintenance personnel from falling to the ground.

[0086] Preferably, the first branch line plate 131 is provided with a limiting plate 133 on one side of the second branch line plate 132, and the limiting plate 133 extends away from the second branch line plate 132.

[0087] For the convenience of understanding, the two ends of the traction rope 4 are set as a first traction end 41 and a second traction end 42, and the two ends of the safety rope 5 are set as a first connecting end 51 and a second connecting end 52. During installation, the second connecting end 52 is first connected with the wire distribution frame 13, then the first traction end 41 is arranged in the first rope passing groove 112, and the first connecting end 51 is arranged in the second rope passing groove 161. Then, the first traction end 41 and the first connecting end 51 need to be lifted upward by using a drone and cross the power transmission wire 100. After crossing the power transmission wire 100, the drone brings the first connecting end 51 and the first traction end 41 to the hands of the maintenance personnel. Then, the maintenance personnel can pull the safety rope 5 and the traction rope 4 from below, and the safety rope 5 drives the wire distribution frame 13 to move upward to abut against the wire hanging part 11, so that the wire distribution frame 13 moves together with the wire hanging part 11 until the power transmission wire 100 enters the wire hanging groove 111 of the wire hanging part 11. Specifically, the wire hanging part 11 has an incoming wire part and an outgoing wire part arranged oppositely. During installation, the incoming wire part is first contacted with the power transmission wire 100 under the drive of the safety rope 5 and the traction rope 4, and the wire hanging part 11 is gradually hung on the power transmission wire 100. During disassembly, the maintenance personnel pulls the traction rope 4 located at the incoming wire part to pull the wire hanging part 11 out of the power transmission wire 100 from the outgoing wire part. In order to improve the installation efficiency of the wire hanging part 11, the incoming wire part is provided with a guide part 113 which is inclined towards the inside of the wire hanging groove 111. The rope passing opening located on one side penetrates the guide part 113. The guide part 113 is used to guide the power transmission wire 100 to enter the wire hanging groove 111, thereby improving the installation efficiency of the wire hanging mechanism 1.

[0088] In the embodiment, the pressing part 12 is adjacent to the outgoing wire part. During disassembly, the second traction end 42 is tilted to form a certain angle with the vertical direction, so that one end of the traction rope 4 can push the pressing part 12, thereby driving the other end of the pressing part 12 to rotate, so as to abut the traction rope 4 against the first rope passing groove 112, and then the wire hanging part 11 is pulled out of the power transmission wire 100 together with the traction rope 4.

[0089] In the embodiment, as shown in the figure, Figure 3 in order to avoid the reduction of the strength of the wire hanging part 11, the first rope passing groove 112 is not directly arranged on the wire hanging part 11. A first guard plate 14 is arranged on the side of the wire hanging part 11 away from the wire hanging groove 111, and the first rope passing groove 112 is arranged in the first guard plate 14. Specifically, the first guard plate 14 includes a first plate, a second plate and a third plate. The second plate is connected with the first plate and the third plate at an included angle on both sides to form the first rope passing groove 112.

[0090] Optionally, the first plate, the second plate and the third plate are integrally bent and formed. The first guard plate 14 integrally formed has high structural strength and is not easy to be damaged.

[0091] Preferably, the threading port is trumpet-shaped, and the cross-sectional area of the first threading groove 112 gradually decreases from the threading port in the direction of the middle part close to the first threading groove 112, in other words, the cross section of the first threading groove 112 gradually increases in the direction of the threading port, so as to facilitate the pulling of the rope 4 through the first threading groove 112 and improve the installation efficiency.

[0092] Specifically, the wire hanging part 11 is made of insulating material, and when the wire hanging part 11 is hung on the power transmission conductor 100, the wire hanging part 11 can be in insulating connection with the power transmission conductor 100.

[0093] During the maintenance process, relative sliding may occur between the wire hanging part 11 and the power transmission conductor 100, and when the wire hanging part 11 slides relative to the power transmission conductor 100, friction occurs between the wire hanging part 11 and the power transmission conductor 100, which causes wear of the power transmission conductor 100. In the embodiment, the anti-wear pad 15 is arranged in the wire hanging groove 111, and the anti-wear pad 15 is used to abut against the power transmission conductor 100 to reduce the contact area of the wire hanging mechanism 1 with the power transmission conductor 100, so as to reduce the wear of the power transmission conductor 100 when the wire hanging part 11 moves.

[0094] Optionally, the anti-wear pad 15 is locked in the wire hanging groove 111 by the locking part to prevent the anti-wear pad 15 from falling accidentally. Preferably, the locking part is a locking screw, and the wire hanging part 11 is provided with a mounting hole on the side away from the wire hanging groove 111, the mounting hole being communicated with the wire hanging groove 111, the anti-wear pad 15 being provided with a threaded hole corresponding to the mounting hole, and the locking screw being screwed in the threaded hole through the mounting hole to realize the installation and fixation of the anti-wear pad in the wire hanging groove 111, which is convenient to disassemble and has high stability. In other embodiments, the anti-wear pad 15 and the wire hanging part 11 can also be connected by clamping, buckling, welding or other connection methods, which are not limited to the embodiment.

[0095] Specifically, the wire hanging mechanism 1 further comprises a second guard plate 16, and the second guard plate 16 is arranged between the two first guard plates 14. The second guard plate 16 is provided with a second threading groove 161, and the safety rope 5 is arranged in the second threading groove 161 to prevent the safety rope 5 from sliding left and right.

[0096] Optionally, the rack 21 is provided with a guide rope ring 25, and the traction rope 4 is arranged in the guide rope ring 25 before being connected to the climbing rope assembly 23 to limit and guide the traction rope 4.

[0097] The application also provides a disassembly method of the lifting device for power maintenance, as shown in the drawings, the lifting device for power maintenance of any of the above embodiments comprises the following steps: Figures 1 to 9

[0104] Step S220, taking the plane formed by the central axis of the power transmission conductor 100 extending in the vertical direction as a set reference plane, by pulling the second traction end 42, increasing the angle between the traction rope 4 and the set reference plane, making one end of the pressing piece 12 of the lifting device for power maintenance rotate, and making the other end of the pressing piece 12 press on the traction rope 4;

[0105] Step S230, continuously pulling the second traction end 42 downward, the traction rope 4 drives the wire hanging piece 11 to rotate along the power transmission conductor 100, until the wire hanging piece 11 is separated from the power transmission conductor 100;

[0106] Step S230, continuously pulling the traction rope 4 and the safety rope 5 until the wire hanging piece 11 falls to the ground to complete the disassembly of the lifting device for power maintenance.

[0107] The lifting device for power maintenance is installed and dismounted on the power transmission wire 100 without the maintenance personnel climbing the high altitude, has high dismounting efficiency and low operation danger coefficient. During installation, the unmanned aerial vehicle replaces the maintenance personnel to cross the traction rope 4 and the installation rope over the power transmission wire 100, then the unmanned aerial vehicle pulls the first traction end 41 and the first connecting end 51 downward, so that the maintenance personnel can hold the traction rope 4 and the safety rope 5 of the end and continue to pull the safety rope 5 downward, so that the wire hanging piece 11 moves upward together with the wire distribution frame 13, the wire hanging piece 11 is gradually hung on the power transmission wire 100 by the guide part 113 of the wire hanging piece 11, and the safety rope 5 can drive the wire distribution frame 13 to the lower side of the wire hanging piece 11 to separate the upper and lower power transmission wires 100, so as to complete the installation of the wire hanging mechanism 1 on the power transmission wire 100. When the maintenance is completed, the first traction end 41 and the second traction end 42 are dismounted from the winch mechanism 2, the angle between the second traction end 42 and the set reference surface is adjusted, one end of the traction rope 4 drives the pressing piece 12 of the wire hanging mechanism 1 to rotate, the other end of the pressing piece 12 is pressed on the traction rope 4, the second traction end 42 is continuously pulled downward, the traction rope 4 drives the wire hanging piece 11 to rotate along the power transmission wire 100, and the wire hanging piece 11 falls to the ground after being separated from the power transmission wire 100, so as to complete the dismounting of the wire hanging mechanism 1. It can be seen that, by using the unmanned aerial vehicle and the special design of the wire hanging mechanism 1, the installation and dismounting of the wire hanging mechanism 1 on the power transmission wire 100 do not need the maintenance personnel to climb the high-altitude power transmission wire 100, the dismounting efficiency is high, the maintenance efficiency is improved, the operation is simple, and the danger coefficient of the maintenance personnel is reduced.
