[0002] When the high-voltage transmission line is under live maintenance, the operators on the tower need to carry the transfer rope to the tower to hang at the work point. This operation method has the following shortcomings:

[0003] First, the average height of the UHV transmission line tower is more than 80m. When workers climb the tower with ropes, they consume a lot of physical energy, take a long time, and have low work efficiency.

[0004] Second, due to the complex working environment, the transmission rope carried by the operator swings in the air under the action of wind, and the non-directional and non-quantitative tension generated can easily cause the operator to fall from a high altitude;

[0006] The purpose of the present invention is to develop a traction device for hanging and removing transmission ropes on conductors, ground wires and crossarms based on unmanned aerial vehicles in order to reduce the labor intensity of tower maintenance workers and improve work efficiency.

After the guide member 2802 is successfully aligned with the peripheral member 6, the connection seat 200 is separated from the swing arm 110, and the traction device body falls under the action of gravity. Fig.13 In the state, the peripheral component 6 touches the lower end of the recovery link 290, the recovery link 290 slides up, and the two sets of ejector rods 240 eject the two sets of first wire wheels 250 on both sides, and the first wire wheels 250 fall to the ground, and the two sets of recovery wires can be released to the ground. Figure 1 As shown, the first recovery line 7001 on the left first wire wheel 250 and the second recovery line 7002 on the right first wire wheel 250 are dropped along the two sides of the peripheral component 6 respectively.

[0062] The traction line release mechanism comprises a traction line fixing device 4, wherein a cavity is provided in the traction line fixing device 4.

[0063] The bottom 440 of the traction line fixing device is a slope structure that is high in the middle and gradually becomes lower towards the baffles 420 on both sides; two groups of second wire wheels 430 are placed in the cavity, that is, the two groups of second wire wheels 430 are placed on the inclined surfaces on both sides, and the two ends of a group of traction lines 7003 are respectively wound around the two groups of second wire wheels 430, and a group of baffles 420, that is, blocking members, are hinged on the left and right sides of the traction line fixing device 4. A moving mechanism is provided in the traction line fixing device 4 to drive the opening and closing of the baffles 420. The moving mechanism includes a gear 410, a rotating shaft 4201 and a connecting member 4203, that is, the upper end of the baffle 420 is hinged to the traction line fixing device 4 through the baffle rotating shaft 4201, and a torsion spring 4204 is installed on the baffle rotating shaft 4201 to prevent the two groups of second wire wheels 430 from squeezing the baffle 420 apart to slide along the inclined surface. Two groups of gears 410 that mesh with each other are provided on the inner wall of the traction line fixing device 4, such as Fig.11 As shown, the lower end of the second recovery line 7002 led out from the recovery line release mechanism 2 is wrapped around the gear surface on the peripheral side of the gear shaft of the left gear 410, and a connecting piece 4203 is provided on the rotating joint 4202 of the baffle rotating shaft 4201 on both sides. In this embodiment, it is a connecting line, and the other ends of the two sets of connecting lines are respectively connected to the gear surface on the peripheral side of the gear shaft on the back side of the gear 410 on the same side. The two sets of baffles 420, the connecting piece 4203 and the two sets of gears 410 form a symmetrical release structure.

[0064] A long groove 450 is provided at the bottom 440 of the traction line fixing device, which passes through the bottom 440 of the traction line fixing device and extends toward the two sets of baffles 420. The gear 5 is located directly below the long groove 450. The second recovery line 7002 that has fallen to the ground is pulled (this is the first pull) to drive the two sets of gears 410. The two sets of gears 410 rotate in the downward direction of the meshing tooth surfaces. At the same time, the rotating joint 4202 is pulled through the connecting piece 4203 to overcome the reverse force of the torsion spring 4204 to open the two sets of baffles 420.

[0065] like Fig.12 In the state shown, during the release of the two sets of second wire wheels 430, the traction line 7003 falls from the long groove 450 and is connected to the pulley groove of the pulley 5 below. The staff on the bottom ties the transfer rope to one end of the traction line 7003 and pulls the other end of the traction line 7003 to deliver the transfer rope to the tower. There is no need for the operators to carry it on the tower, and the operation is simple and convenient.

[0066] The present invention also has a traction device recovery mechanism for recovering the completed transfer operation. The traction recovery mechanism includes the recovery ornament 260, the second elastic member 2603, the hanging member 280, and the locking member 270 mentioned in the above text. Fig.13The recovery pendulum rotating shaft 2604 is provided with a toggle member 2605, so that the toggle member 2605 and the recovery pendulum 260 rotate coaxially, and a locking member 270 is provided below the toggle member 2605. Figure 6 As shown, the locking member 270 is slidably matched with the recovery line fixing device 210, and can slide horizontally left and right in the recovery line fixing device. The hanging member 280 is hinged on the recovery line fixing device 210, and the hanging member 280 body around its hanging member hinge shaft 280 is a rectangular square sheet. When the locking member 270 slides to the leftmost end, the sliding member 270 is stuck between the upper end of the hanging member 280 body and the recovery line fixing device 210, so that the entire hanging member 280 is locked and cannot swing. When the traction device is recovered, the first recovery line 7001 or the second recovery line 7002 is pulled (this is the second pull), and the recovery pendulum 260 rotates. At the same time, compared with the first pull, the second pull force needs to be greater than the first pull, so as to overcome the reverse force of the second elastic member 2603, and at the same time drive the toggle member 2605 along Figure 6 As shown in the figure, the toggle member 2605 pushes the locking member 270 to slide to the right. The locking member 270 slides to the right this time due to the greater force, and completely slides out from between the upper end of the hanging member 280 body and the recovery line fixing device 210, so that the hanging member 280 is unlocked and rotated. Fig.14 and Fig.15 The state shown; (it should be noted that: since the initial pulling force is small, the rotation stroke of the recovery ornament 260 is small, so the toggle member 2605 will not push the locking member 270 to slide to the right or the stroke of pushing the locking member 270 to slide to the right is not enough to unlock the suspension member 280), the entire traction device is detached from the external member 6, since the first recovery line 7001 and the second recovery line 7002 are respectively located on both sides of the external member 6, at this time, during the falling process of the traction device, the first recovery line 7001 is overlapped on the external member, only need to hold the first recovery line 7001 tightly and slowly release the line, the entire traction device 6 can be safely from the bottom of the tower to the bottom, during the process, there is no need for operators to go up the tower to dismantle it, only ground personnel need to operate it, which is safe and efficient and reduces labor intensity.
