DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] Embodiment: A live wire traction device, such as Figure 1-Figure 4As shown, it includes an automatic telescopic frame 1, a moving wheel 101, a first mounting plate 102, an annular electric slide rail 1021, a mechanical arm 104, a clamping claw 1041, a first traction mechanism 2 and a second traction mechanism 201. The moving wheel 101 is installed at the lower part of the automatic telescopic frame 1. The moving wheel 101 is an electric wheel, so that the device can move automatically. The upper part of the automatic telescopic frame 1 is connected to the first mounting plate 102, and the annular electric slide rail 1021 is installed on the first mounting plate 102 by bolts. The mechanical arm 104 is installed on the first mounting plate, and the clamping claw 1041 is connected to the mechanical arm. The annular electric slide rail 1021 is provided with a first traction mechanism 2 and a second traction mechanism 201. The mechanical arm 104 is located between the first traction mechanism 2 and the second traction mechanism 201. The first traction mechanism 2 includes a slider 21, an electric push rod 2 2. A semi-arc plate 23, a fixed rod 231, a clamping block 232, a connecting plate 233, an elastic member 234 and a connecting rod 235. A slider 21 is slidably connected to the annular electric slide rail 1021. An electric push rod 22 is installed on the slider 21 through a fixing member. A semi-arc plate 23 is connected to the telescopic end of the electric push rod 22. The semi-arc plate 23 is symmetrically slidably connected to the fixed rod 231. The clamping blocks 232 for fixing the wires are connected to the sides of the fixed rods 231 that are close to each other. The fixing rods 231 are connected to connecting plates 233. The connecting plates 233 and the semi-arc plate 23 are connected to elastic members 234 through spring seats. The initial state of the elastic members 234 is a stretched state. The fixing rods 231 are connected to connecting rods 235. The second traction mechanism 201 has the same component structure as the first traction mechanism 2.

[0028] like Figure 1-Figure 4 As shown, it also includes a tensioning mechanism 3, the slider 21 is provided with a tensioning mechanism 3, the tensioning mechanism 3 includes a telescopic rod 31, a vertical electric slide rail 32 and a guide rod 33, the slider 21 is connected with the telescopic rod 31, the upper end of the telescopic rod 31 is installed with a vertical electric slide rail 32 through a fixing member, the vertical electric slide rail 32 is connected to the semi-arc plate 23, the vertical electric slide rail 32 is slidably connected with the guide rod 33 up and down, the left and right sides of the guide rod 33 are provided with inclined surfaces, and the left and right parts of the guide rod 33 are both located in the semi-arc plate 23. The guide rod 33 is slidably connected to the semi-arc plate 23 between the arc plate 23 and the connecting rod 235, driving the vertical electric slide rail 32. The vertical electric slide rail 32 will move the guide rod 33 upward, and the connecting rod 235 will move along the inclined surface on the guide rod 33 toward the middle of the semi-arc plate 23. During this process, the elastic member 234 will move the clamping block 232 toward the middle. When the connecting rod 235 contacts the middle of the guide rod 33, it indicates that the connecting end of the new wire is clamped and fixed by the clamping block 232.

[0029] like Figure 5 and Figure 6As shown, it also includes a storage mechanism 4. The first mounting plate 102 is provided with a storage mechanism 4. The storage mechanism 4 includes a second mounting plate 41, a cabinet 42, a drawer 43 and a display frame 44. The first mounting plate 102 is connected to the second mounting plate 41, and the second mounting plate 41 is connected to the cabinet 42. The cabinet 42 is slidably connected with a drawer 43 for storing maintenance tools, and the second mounting plate 41 is connected to the display frame 44. The drawer 43 is opened, and the maintenance tools to be used are placed in the drawer 43, and then the drawer 43 is reset, thereby reducing the weight of the staff. During the rising process of the first mounting plate 102, the staff can take out the tools to be used later from the drawer 43 and place them on the display frame 44, which is convenient for taking them for subsequent use, effectively improving the operating efficiency of the staff and saving time.

[0030] like Figure 7 and Figure 8 As shown, it also includes a winding mechanism 5. The first mounting plate 102 is provided with a winding mechanism 5. The winding mechanism 5 includes a guide rail 51, a third mounting plate 52, a motor 53 and a rotating shaft 54. The first mounting plate 102 is connected with the guide rail 51, and the third mounting plate 52 is slidably connected to the guide rail 51. The motor 53 is installed on the third mounting plate 52 through a fixing member, and the output shaft of the motor 53 is connected with the rotating shaft 54 ​​through a coupling. The staff cuts off the old wire and fixes the cut end on the rotating shaft 54, and then drives the motor 53 to rotate the rotating shaft 54, so as to roll up the old wire. This not only allows the old wire to be quickly rolled up, thereby improving the maintenance efficiency, but also facilitates the subsequent sorting and reuse of the old wire.

[0031] like Figure 1 , Figure 2 and Figure 3 As shown, it also includes an operating table 103 and an electric pulley 24. The operating table 103 is symmetrically connected to the first mounting plate 102, and the electric pulley 24 is installed on the clamping block to drive the electric pulley 24 on the first traction mechanism 2. As the electric pulley 24 rotates, the new wire will move toward the second traction mechanism 201. After the connecting end of the new wire is displaced to a certain distance in front of the second traction mechanism 201, the electric pulley 24 is closed, so that the device can fix the new wire while moving the new wire.

[0032] The device is suitable for traction of live wires at high places, and is particularly suitable for use when there are obstacles in the path of wire traction, and the parts of the device that need to contact the live wires are all made of high-quality insulating materials; when the device is to be used, first open the drawer 43, put the insulating tools and voltage detectors that will be used later into the drawer 43, and then reset the drawer 43 to reduce the weight of the staff; drive the electric wheel to move the device to the use site, and then adjust the position of the device according to the position of the old wire. After adjusting the position, lay an insulating mat on the operating table 103 to increase the safety of live work. After the staff put on the insulating work clothes, they stand on the operating table with the new wire roll. The staff then places the tools on the insulating pad on 103, and then drives the automatic telescopic frame 1, which will rise with the first mounting plate 102. During the rising process of the first mounting plate 102, the staff can take out the tools needed later from the drawer 43 and place them on the display frame 44, which is convenient for taking them out later, effectively improving the staff's operating efficiency and saving time. After rising to a height where the staff can touch the old wire, the automatic telescopic frame 1 is closed, and the staff will use an insulating tool to cut off the part of the old wire that needs to be replaced, and connect the cut end of the old wire to one end of the new wire. After the connection is completed, use a voltage detector to detect whether the new wire has electricity and whether the voltage in the new wire is stable, and then drive the automatic telescopic frame 1. The mechanical arm 104 causes the clamping claw 1041 of the mechanical arm 104 to clamp the charged new wire, and places the other end of the charged new wire into the semi-arc plate 23 of the first traction mechanism 2, and then drives the vertical electric slide rail 32, the vertical electric slide rail 32 will move upward with the guide rod 33, and the connecting rod 235 will move along the inclined surface on the guide rod 33 to the middle of the semi-arc plate 23. During this process, the elastic member 234 will move toward the middle with the clamping block 232. When the connecting rod 235 contacts the middle of the guide rod 33, it indicates that the connection end of the new wire is clamped and fixed by the clamping block 232, and the mechanical arm 104 is driven to release the clamping claw 1041 from clamping the new wire; then the electric push rod 22 is driven to rise with the semi-arc plate 23. At this time, the vertical electric slide rail 32 will also rise together, the telescopic rod 31 will be stretched, and the semi-arc plate 23 will rise together with the new wire. When the height of the new wire is almost the same as that of the old wire, the electric push rod 22 will be closed, and then the electric wheel will be driven to move the device to the direction of the old wire. When encountering an obstacle, the device will first stop in front of the obstacle, and then drive the annular electric slide rail 1021. The annular electric slide rail 1021 will move the first traction mechanism 2 to the front side of the obstacle, and then move the second traction mechanism 201 to the bottom of the obstacle and pass through the bottom of the obstacle to the other side of the obstacle. The second traction mechanism 201 is adjusted to align the second traction mechanism 201 with the first traction mechanism 2 in the horizontal direction;If the position of the second traction mechanism 201 is higher than the bottom surface of the obstacle at this time and it is impossible to move directly from under the obstacle, the automatic telescopic frame 1 can be driven first to move the automatic telescopic frame 1 downward with the device until the second traction mechanism 201 can pass under the obstacle. After the two traction mechanisms are aligned, the electric pulley 24 on the first traction mechanism 2 is driven. As the electric pulley 24 rotates, the new wire will move toward the second traction mechanism 201. After the connection end of the new wire is displaced to a certain distance in front of the second traction mechanism 201, the electric pulley 24 is closed, so that the device can fix the new wire while also moving the new wire. The vertical electric slide rail 32 on the second traction mechanism 201 is driven. The vertical electric slide rail 32 will move upward with the guide rod 33, so that the clamping block 232 on the second traction mechanism 201 clamps the new wire, so that the device can automatically complete the work of connecting the wires in the two traction mechanisms. The vertical electric slide rail 32 on the first traction mechanism 2 is driven again to move the guide rod 33 downward, thereby releasing the clamping of the new wire by the first traction mechanism 2. After that, the electric push rod 22 on the first traction mechanism 2 is driven to lower the semi-arc plate 23, thereby ensuring that the first traction mechanism 2 can pass under the obstacle, and then the electric wheel is driven to continue to pull the new wire, so that the device can pull the new wire around the obstacle under the condition of being energized, and the device does not need the staff to hold the energized wire to pull, which effectively ensures the personal safety of the staff, and also prevents the wire from being entangled with the obstacle, effectively ensuring the circuit safety, and minimizing the wire consumption, effectively saving the laying cost; when encountering the obstacle again, the above steps of bypassing the obstacle are alternately implemented on the first traction mechanism 2 and the second traction mechanism 201 by using the annular electric slide rail 1021. It should be noted that when the device is used to repeatedly bypass the obstacle and pull the wire to move, the staff can control the automatic telescopic frame 1 to shrink to drive the first mounting plate 102 to descend and then lower the center of gravity of the device, thereby improving the safety of the device when moving. At the same time, the electric push rod 22 is adaptively extended to maintain the height of the clamping block 232 and the new wire clamped therein to the wire pulling height. ;

[0033] When the device pulls the new wire to the front side of the connection with the other end of the old wire, the height of the traction mechanism that clamps the new wire and the height of the device are adjusted according to the height of the staff and the old wire at this time, so that the staff can rise to a height that is convenient for operating the wire, and the height of the new wire is consistent with the height of the old wire at this time. The staff cuts off the port connection of the old wire and fixes the old wire that has just been cut on the rotating shaft 54, and then drives the motor 53 to rotate the rotating shaft 54, so as to reel up the old wire. This not only can quickly reel up the old wire and improve the maintenance efficiency, but also facilitates the subsequent sorting and reuse of the old wire; after completing the reeling of the old wire, drive the mechanical arm 104 to make the clamping claw 1041 clamp the charged new wire and move it to the side close to the old wire, so that the new wire is in a taut state, and then adjust the driving mechanical arm 104 to tighten the connection end of the new wire with The connecting ports of the old wires are docked, and the staff uses maintenance tools to connect the connecting ends of the new wires with the connecting ports of the old wires, thereby completing the traction work of the high-altitude live wires; and because the new wires are in a taut state, the new wires are neat and beautiful after installation, and at the same time, the potential safety hazards caused by loose wires are reduced. The device has a high degree of automation, which reduces the workload of staff to manually adjust the position of the traction live wires, and effectively improves the safety of the operation; and the third mounting plate 52 can be moved according to the docking direction, so that the rotating shaft 54 ​​can always be close to the wire that needs to be reeled in, effectively improving the reeling efficiency and reeling flexibility of the device. After completing the work, the automatic telescopic frame 1 is driven to lower and reset the device. During this process, the staff can store the insulating tools back into the drawer 43, then remove the reeled old wire coil, and close the device.
