[0039] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0040] In the net enclosing operation, ZL2023116968454 proposes a walking mechanism applicable to a transmission line crossing protection net erection device, including a mounting plate, a first walking wheel module, and a second walking wheel module. The first walking wheel module includes a first driving assembly and a plurality of first walking wheels. The first walking wheels are rotatably arranged on the mounting plate, and at least one first walking wheel is connected to the first driving assembly. The second walking wheel module includes a movable plate, a lifting assembly, a second driving assembly, and a plurality of second walking wheels. The movable plate is connected to the lifting assembly. The second driving assembly is installed on the movable plate. The second walking wheels are rotatably arranged on the movable plate, and at least one second walking wheel is connected to the second driving assembly. The second walking wheels and the first walking wheels are arranged in an alternating up-and-down manner. The lifting assembly is used to drive the movable plate to drive the second walking wheels to move closer to or away from the first walking wheels. This device can press the transmission line from both the upper and lower directions, thereby improving the adhesion of the walking mechanism.

[0041] In the above solution, slipping is likely to occur between the walking wheels and the cable, affecting the walking effect of the walking mechanism on the transmission line.

[0042] In view of this, an embodiment of the first aspect of the present application provides a walking device applicable to a transmission line to effectively solve the foregoing problems.

[0043] Referring to Figures 1 to 5 As shown, an embodiment of the present application discloses a walking device applicable to a transmission line, including a bracket 100, a walking mechanism, and an adjustment mechanism.

[0044] Specifically, the walking mechanism includes a first walking component 210 and a second walking component 220 that are spaced apart on the bracket 100. Both the first walking component 210 and the second walking component 220 include a crawler structure 211. The crawler structure 211 forms a recessed area 231. An accommodation space 230 is enclosed between the recessed areas 231 of the two crawler structures 211. The accommodation space 230 is used to accommodate the cable. The adjustment mechanism is used to adjust the distance between the crawler structure 211 of the first walking component 210 and the crawler structure 211 of the second walking component 220 to change the size of the accommodation space 230.

[0045] Among them, after the cable is placed in the accommodation space 230, the distance between the crawler structures 211 on both sides of the cable can be changed through the adjustment mechanism so that the crawler structures 211 on both sides of the cable are respectively in contact with the cable. In this way, the friction between the cable and the crawler structure 211 can be increased, thereby reducing the slipping situation.

[0046] It should be understood that referring to Figure 1 and Figure 5 , the recessed area 231 is located in the middle of the crawler structure 211. That is to say, the upper contour of the cross-section of the crawler structure 211 generally presents a shape with high sides and low middle, that is, a V shape, and the extending direction of the recessed area 231 is parallel to the length direction of the cable.

[0047] In the walking device provided by the embodiment of the present application, through the coordinated work of the crawler-type first walking component, second walking component, and adjustment mechanism, the functions of clamping the wire and pulling the insulating net are realized. The cable is clamped by the crawler structures 211 of the first walking component 210 and the second walking component 220 to achieve walking. At the same time, the cable is accommodated in the accommodation space 230 enclosed by the upper and lower crawler structures 211, which can increase the force-bearing area between the crawler 2112 and the wire, improve the traction force and stability, reduce the slipping phenomenon, and ensure the safety and reliability of the net sealing operation. At the same time, compared with the traditional manual laying method, the net sealing time is greatly shortened, and the net sealing operation can be completed within a limited time, meeting the strict requirements of the management unit of the crossed facility for the net sealing time. Compared with the traditional net sealing device that requires a large amount of materials such as steel pipes, guy wires, pile drilling, and insulating ropes, the embodiment of the present application can reduce the dependence on these materials and reduce the material cost.

[0048] In some embodiments of the present application, referring toFigures 2 to 4 As shown in Figures 2 to 4 , the crawler structure 211 includes a drive wheel 2111 and a crawler 2112. The drive wheel 2111 is provided with a first engagement portion, and the crawler 2112 is provided with a second engagement portion. The first engagement portion and the second engagement portion are engaged and matched. Among them, the engagement and matching of the first engagement portion and the second engagement portion can reduce the occurrence of slipping between the crawler 2112 and the drive wheel 2111.

[0049] In a possible implementation manner, referring to Figure 3 and Figure 4 , the first engagement portion is specifically an engagement tooth, and the second engagement portion is specifically an engagement groove presented as the inner peripheral surface of the crawler 2112. The engagement groove is matched with the engagement tooth.

[0050] In some embodiments of the present application, please continue to refer to Figure 3 and Figure 4 , the number of drive wheels 2111 is two. The two drive wheels 2111 are arranged at intervals, and the two drive wheels 2111 are respectively connected to different positions of the crawler 2112 in a matching manner. Specifically, the crawler 2112 is sleeved on the outer peripheries of the two drive wheels 2111, and the two drive wheels 2111 rotate synchronously to drive the crawler 2112 to rotate. In this way, the traction force can be improved.

[0051] In some embodiments of the present application, the traveling mechanism includes a first driving structure 240. The first driving structure 240 is installed on the bracket 100, and the first driving structure 240 is used to drive the drive wheel 2111 to rotate so as to drive the crawler 2112 to move.

[0052] In some embodiments of the present application, the traveling assembly includes a second driving structure 250. The second driving structure 250 is used to drive the drive wheel 2111 of the second traveling assembly 220 to rotate so as to drive the crawler 2112 of the second traveling assembly 220 to rotate.

[0053] It should be understood that in the embodiments of the present application, the crawler structures 211 of the first traveling assembly 210 and the second traveling assembly 220 can rotate simultaneously to achieve the function of moving along the cable; or the crawler structure 211 of one of the first traveling assembly 210 and the second traveling assembly 220 can rotate actively, and the crawler structure 211 of the other is not provided with power.

[0054] In the embodiments of the present application, please continue to refer to Figure 3 and Figure 4 , the traveling assembly includes a first driving structure 240 and a second driving structure 250. The first driving structure 240 is used to drive the first traveling assembly 210 to move, and the second driving structure 250 is used to drive the second traveling assembly 220 to move.

[0055] Specifically, the first driving structure 240 is connected to the driving wheel 2111 of the first traveling assembly 210. By driving the driving wheel 2111 to rotate, the crawler 2112 of the first traveling assembly 210 is driven to rotate; the second driving structure 250 is connected to the driving wheel 2111 of the second traveling assembly 220. The second driving structure 250 drives the driving wheel 2111 of the second traveling assembly 220 to rotate, so as to drive the crawler 2112 of the second traveling assembly 220 to rotate. In this embodiment, there is friction between the crawler structures 211 of the first traveling assembly 210 and the second traveling assembly 220 and the cable. When traveling along the cable is realized, the extrusion force between a single crawler structure 211 and the cable can be effectively reduced, which is beneficial to reducing the slipping between the crawler structure 211 and the cable.

[0056] It should be understood that in order to move the traveling device along the cable, the rotation directions of the crawler structures 211 of the first traveling assembly 210 and the second traveling assembly 220 should be opposite. For example, when the crawler 2112 of the first traveling assembly 210 rotates clockwise, the crawler 2112 of the second traveling assembly 220 should rotate counterclockwise.

[0057] In some embodiments of the present application, referring to Figure 3 and Figure 4 , the crawler structure 211 includes at least one driven wheel 2113, and the driven wheel 2113 is arranged on one side of the driving wheel 2111. It is worth mentioning that the outer surface of the contour is also provided with a concave area 231 to increase the contact area between the crawler 2112 near the driven wheel 2113 and the cable, thereby reducing the slipping situation.

[0058] In a possible implementation manner, referring to Figure 4 , the crawler structure 211 includes two driving wheels 2111 arranged at intervals, and three driven wheels 2113 arranged at intervals are provided between the two driving wheels 2111, and each driven wheel 2113 can rotate around its own axis.

[0059] In some embodiments of the present application, referring to Figure 1 and Figure 5 , the first driving structure 240 and the second driving structure 250 are respectively arranged on both sides of the bracket 100. In this way, the weight distribution of the traveling device can be optimized, which is beneficial to keeping the traveling device in force balance, that is, the line connecting the contact points between the two crawler structures 211 and the cable is parallel to the vertical direction. In this way, it is beneficial to increase the frictional force with the cable, thereby reducing the slipping situation.

[0060] In some embodiments of the present application, referring to Figures 1 to 5, The adjustment mechanism includes a driving member 310, a lead screw 320, and a lead screw nut moving block 330. The lead screw 320 is installed on the bracket 100. The lead screw nut moving block 330 is engaged with the lead screw 320. The lead screw nut moving block 330 is connected to one of the first traveling assembly 210 and the second traveling assembly 220. The driving member 310 drives the lead screw 320 to rotate. By driving the rotation of the lead screw 320, the lead screw nut moving block 330 can be driven to move relative to the lead screw 320, so that the first traveling assembly 210 or the second traveling assembly 220 connected to the lead screw nut moving block 330 moves, so as to achieve the purpose of adjusting the size of the accommodation space 230.

[0061] In a possible implementation manner, refer to Figures 1 to 5 , The second traveling assembly 220 includes a mounting frame 221, a driving wheel 2111, a driven wheel 2113, a crawler 2112, and a second driving structure 250. The mounting frame 221 is connected to the lead screw nut moving block 330. There are two driving wheels 2111. The two driving wheels 2111 are rotatably installed at different positions on the mounting frame 221. The driven wheel 2113 is disposed between the two driving wheels 2111. The crawler 2112 is sleeved on the outer circumferences of the driving wheels 2111 and the driven wheel 2113. Among them, the mounting is U-shaped. The second driving structure 250 is installed on the side of the mounting frame 221 away from the lead screw nut moving block 330. The output end of the second driving structure 250 is connected to the driving wheel 2111 to drive the driving wheel 2111 to rotate.

[0062] In some embodiments of the present application, refer to Figure 4 and Figure 5 , The second traveling assembly 220 includes a slide rail 261 and a slider 262. The slide rail 261 is connected to the bracket 100. The slider 262 is slidably connected to the bracket 100, and the slider 262 is connected to the crawler structure 211. Among them, the extending direction of the slide rail 261 is consistent with the axial direction of the lead screw 320.

[0063] An embodiment of the second aspect of the present application discloses a netting device. Refer to Figure 1 and Figure 2 , The netting device includes the traveling device as described above. The netting device further includes a fixing part. The fixing part is installed on the bracket 100 and is used to connect with the insulating net to fix the insulating net.

[0064] In a possible implementation manner, the fixing part includes an annular structure, and the annular structure can facilitate the connection and fixation with the insulating net.

[0065] In a possible implementation manner, refer to Figure 6During the net covering operation, four traveling devices are utilized. Specifically, two of the traveling devices are installed on the same cable, and the other two traveling devices are installed on another cable. A fixing part is installed on the bracket 100 of each traveling device, and each fixing part is fixedly connected to one of the corners of the insulating net. In this way, by driving the four traveling devices to move, the insulating net can be driven to move to the target position.

[0066] An embodiment of the third aspect of the present application discloses a control method, which is applied to the net covering device as described above, and includes the following steps:

[0067] Place the cable in the accommodation space 230, and use the adjustment mechanism to adjust the distance between the crawler structure 211 of the first traveling component 210 and the crawler structure 211 of the second traveling component 220, so that the crawler structure 211 clamps the cable;

[0068] Control the movement of the crawlers 2112 of the first traveling component 210 and the second traveling component 220.

[0069] In this way, the net covering device can move along the extension direction of the cable.

[0070] In the above embodiment, through the coordinated work of the crawler-type first traveling component, the second traveling component and the adjustment mechanism, the functions of clamping the wire and towing the insulating net are realized. In this embodiment, the cable is clamped by the crawler structures 211 of the first traveling component 210 and the second traveling component 220 and walks.
