[0002] In recent years, my country's socioeconomic development and the continuous improvement of people's quality of life have fueled rising societal demands for power supply reliability and the continued advancement of smart grid technology. Live-line work, including distribution, network expansion, troubleshooting, and maintenance, has become increasingly common. However, traditional live-line work methods, which rely on workers, are labor-intensive, pose high safety risks, and present a harsh working environment. Wearing thick insulating clothing can feel like a sauna, especially in the summer. Live-line work exposes workers to high voltages, strong electric fields, and high temperatures, which can easily lead to personal injury and death, and significantly reduces work efficiency. This is particularly true in complex terrain, such as mountainous areas and fields, where live-line work vehicles are inaccessible, leaving workers unable to perform their work.

The jackhammer assembly support plate 40 and the jackhammer assembly support frame 13 are fixed together to the piston rod slide of the left feed slide cylinder 30;

[0027] The left conversion head 36 and the right conversion head 37 are respectively arranged inside the left clamping block frame 18 through the left bearing 38 and the right bearing 39. The left universal flexible shaft 11 and the right universal flexible shaft 12 respectively pass through the corresponding through holes opened on the left clamping block frame 18. The two parallel shafts on the side of the left clamping block pressure plate 21 and the hole opened on the side of the left clamping block frame 18 form a moving pair;

[0028] The compression spring 22 is sleeved on two parallel axes on the side of the left clamping block pressure plate 21 , and its two ends are pressed against the end surface of the left clamping block pressure plate 21 and the inner side surface of the left clamping block frame 18 respectively.

The upper positioning cylinder frame 31 and the lower positioning cylinder frame 32 are symmetrically mounted on the upper and lower sides of the right clamping block frame 25. The two screw bit sleeves 35 are fastened to the right clamping block frame 25 by set screws respectively. The two guide columns on the side of the right clamping block plate 26 and the two holes in the right clamping block frame 25 respectively form a moving pair. The two ends of the two compression springs 22 set on the two parallel axes of the end face of the right clamping block plate 26 are pressed against the side of the right clamping block plate 26 and the inner side of the right clamping block frame 25.

[0030] A further technical solution of this embodiment is that the upper and lower working surfaces of the right clamping block 1 are both arranged to be arc surfaces, and their sizes are respectively adapted to the fire cable 5 and the main line cable 6. Two through holes are provided in the middle of the right clamping block 1, and a rectangular through groove is provided on the left clamping block 2; the fasteners include a plurality of fastening nuts 4 and fastening screws 3, one end of the two fastening screws 3 is clamped in the rectangular through groove, and the other end of the two fastening screws 3 respectively passes through the corresponding through holes of the right clamping block 1 and engages with the fastening nuts 4 to be connected to the left nut air screw sleeve 19 and the right nut air screw sleeve 20.

[0031] A further technical solution of this embodiment is that a positioning blocking pin 17 is installed on the piston rod of the positioning blocking cylinder 14, and its cylinder body is installed on the positioning blocking cylinder support frame 15. When the piston rod of the positioning blocking cylinder 14 is extended, the positioning blocking pin 17 fixed on it is inserted into the left clamping block frame 18 to block the left clamping block frame 18 from feeding.

[0032] A further technical solution of this embodiment is that the support plate frame includes a U-shaped support plate, a right-feeding double-rod cylinder support block 28 and a left-feeding slide cylinder support block 29 respectively installed on both sides of the U-shaped groove, the left-feeding slide cylinder 30 and the right-feeding double-rod cylinder 27 are respectively mounted on the left-feeding slide cylinder support block 29 and the right-feeding double-rod cylinder support block 28, and the positioning blocking cylinder support frame 15 is installed on the U-shaped support plate.

[0033] According to a further technical solution of this embodiment, the end of the screw bit sleeve 35 is configured to be hexagonal.

[0034] Working principle of the present invention:

[0035] 1) First, place the two fastening nuts 4 in the left nut air screw sleeve 19 and the right nut air screw sleeve 20 respectively, and press the left clamping block 2 and the right clamping block 1 into the left clamping block frame 18 and the right clamping block frame 25 through the left clamping block pressure plate 21 and the right clamping block pressure plate 26 respectively, and clamp the ends of the two fastening screws 3 in the corresponding two screw bit sleeves 35 respectively, to prepare for fastening the main line cable 6 and the fire cable 5.

[0036] 2) The device is then transported to the bottom of the high-altitude main cable 6 and lifted to a suitable height. Subsequently, the positioning and centering clamping device 42 is used to quickly and accurately center and position the distribution live operation robot automation device at the appropriate position of the high-altitude cable. The high-altitude main cable 6 insulation layer is then quickly stripped by the plum blossom self-release clutch pneumatic thread feed device 44 and the double-tooth relay driven spiral rotary insulation stripping device 43. The connecting line clamping and conveying device 45 then clamps the stripped insulation layer of the fire cable 5 and accurately delivers it to the upper docking position of the high-altitude cable stripping section, thereby achieving rapid stripping of the insulation layers of the main cable 6 and the fire cable 5.

[0037] 3) Then the piston rods in the right feeding double-rod cylinder 27 and the left feeding slide cylinder 30 are fed to the middle respectively, and at the same time the piston of the positioning blocking cylinder 14 is extended. When the left feeding slide cylinder 30 feeds to the blocking position of the positioning blocking pin 17 at the front end of the piston rod of the positioning blocking cylinder 14, it is blocked and stops. The right feeding double-rod cylinder 27 moves to the left until the two arc surfaces of the right clamping block 1 on it touch the main line cable 6 and the fire cable 5 and stop moving. Then the two pairs of semicircles at the front end of the upper positioning clamp 33 and the lower positioning clamp 34 align the two fastening screws 3 of the fastening clamp so that the two fastening screws 3 installed in the right fastening device body can be accurately aligned with the two screw holes in the middle of the left clamping block 2 pre-installed in the left fastening device body. Then the piston of the positioning blocking cylinder 14 retracts, and the left feeding slide cylinder 30 breaks away from the blockage of the positioning blocking pin 17 at the front end of the piston rod of the positioning blocking cylinder 14 and continues to feed. The pneumatic blaster 7 rotates the right fastening pneumatic blaster 8, which is transmitted between the left universal flexible shaft 11, the right universal flexible shaft 12, the left conversion head 36, and the right conversion head 37 to drive the left nut air batch sleeve 19 and the right nut air batch sleeve 20 to rotate. The left nut air batch sleeve 19 and the right nut air batch sleeve 20 drive the two fastening nuts 4 therein to rotate and feed forward, and the right clamping block 1 and the left clamping block 2 are tightened by the engagement of the two fastening nuts 4 and the two fastening screws 3. The bridging cable 5 and the main line cable 6 are fastened and bridging. During the tightening process, since the tightening force of the bolts is greater than the clamping force of the left clamping block pressure plate 21 and the right clamping block pressure plate 26 on the left clamping block 2 and the right clamping block 1, the right clamping block 1 and the left clamping block 2 are slowly separated from the right clamping block frame 25 and the left clamping block frame 18 during the tightening process. After the tightening and bridging is completed, the piston rods of the right feed double-rod cylinder 27 and the left feed slide cylinder 30 are retracted respectively to achieve reset.

[0038] 4) Since the center distance of the rotating shafts of the left pneumatic cannon 7 and the right fastening pneumatic cannon 8 is much larger than the distance between the two bolt center holes of the right clamping block 1 and the left clamping block 2, the rotating shafts of the left pneumatic cannon 7 and the right fastening pneumatic cannon 8 cannot be directly connected to the left nut air screw sleeve 19 and the right nut air screw sleeve 20. Due to the limitation of the operating space, the present invention adopts the transition method of the left universal flexible shaft 11 and the right universal flexible shaft 12 to ensure that the rotation of the left pneumatic cannon 7 and the right fastening pneumatic cannon 8 can be achieved in a limited operating space.

[0039] The present invention is used in the operation of the power distribution live working robot automation device as follows:

[0040] In the first step, the device is first transported to the bottom of the aerial cable 6 and lifted to a suitable height by the gyroscope self-balancing lifting tripod line device 41. Then, the positioning and centering clamping device 42 is used to quickly and accurately center the distribution live working robot automation device at the appropriate position of the aerial cable. Then, it is symmetrically clamped on the aerial cable, and the tensioning and straightening cylinder is used to tension and straighten the working end of the aerial cable.

[0041] In the second step, the pneumatic power feed device of the plum blossom self-release clutch pneumatic thread feed device 44 is clamped on the overhead cable through the left and right thread guide clamping blocks, and the cutting tool is fed to the appropriate feed amount. After the feed is completed, the pneumatic power feed device retreats and automatically separates from the cutting tool through the plum blossom self-release clutch device;

[0042] The third step is to drive the cutting tool to perform a spiral rotary cutting motion on the high-altitude cable by the double-tooth relay driving the spiral rotary insulation stripping device 43's rotary motion and the left and right feed motion, thereby completing the rapid stripping of the insulation layer of the high-altitude main line cable 6. When the insulation layer of the high-altitude cable is quickly stripped to a suitable length, the cutting tool is automatically combined with the cutting tool through the plum blossom self-disconnecting clutch device, so that the cutting tool can be quickly retracted. At this stage, the stripping of the high-voltage cable insulation layer is completed;

[0043] The fourth step is to clamp the stripped insulation layer of the fire cable 5 through the clamping and conveying device 45 and accurately deliver it to the upper docking position of the aerial cable stripping section.

[0044] Step 5: Clamp, deliver, and install a pair of split fastening clamps using the fastening clamp installation fastening device 46: Place the main line cable 6 and the fire cable 5 between the left clamping block 2 and the right clamping block 1 in advance, and use the fastening device of the present invention to automatically fasten and fire them, thereby facilitating the automated live fire work of the power distribution live operation robot automation device;

[0045] In the sixth step, the insulating box is automatically delivered and installed on the fastened fastening clamp through the insulating box installation device 47 to ensure the insulation of the fire.

[0046] The above-described embodiments are merely descriptions of preferred implementations of the present invention and are not intended to limit the scope of the present invention. Without departing from the principles and essence of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the scope of protection determined by the claims of the present invention.
