[0030] like Figures 2 to 5 As shown, it is a walking mechanism suitable for a device for erecting a protection net across a transmission line according to an embodiment of the present invention.

[0031] See also Figure 2-Figure 4 The walking mechanism 10 of the device for erecting a protective net for a power transmission line crossing an embodiment of the present invention includes a mounting plate 11, a first walking wheel module 12, and a second walking wheel module 13. The first walking wheel module 12 includes a first driving assembly and a plurality of first walking wheels 122. The first driving assembly is mounted on the mounting plate 11. The first walking wheels 122 are rotatably arranged on the mounting plate 11, and at least one first walking wheel 122 is connected to the first driving assembly. The second walking wheel module 13 includes a movable plate 131, a lifting assembly 132, a second driving assembly, and a plurality of A second running wheel 134, a lifting assembly 132 is installed on the mounting plate 11, the movable plate 131 is connected to the lifting assembly 132, the second driving assembly is installed on the movable plate 131, the second running wheel 134 is rotatably set on the movable plate 131, and at least one second running wheel 134 is connected to the second driving assembly, the second running wheel 134 and the first running wheel 122 are staggered one above and one below, and the lifting assembly 132 is used to drive the movable plate 131 to drive the second running wheel 134 to move close to the first running wheel 122 or away from the first running wheel 122.

[0032] In this embodiment, the first running wheel 122 is on the top and the second running wheel 134 is on the bottom. In other embodiments, the second running wheel 134 may be on the top and the first running wheel 122 may be on the bottom.

[0033] When it is necessary to tighten the transmission line, the first running wheel 122 is first placed on the transmission line, and then the lifting component 132 drives the movable plate 131 to drive the second running wheel 134 to move close to the first running wheel 122, and the first running wheel 122 and the second running wheel 134 cooperate to tighten the line; when it is necessary to release, the lifting component 132 drives the movable plate 131 to drive the second running wheel 134 to move away from the first running wheel 122, so that the second running wheel 134 leaves the transmission line.

[0034] It can be understood that the walking mechanism 10 of the embodiment of the present invention can be used for a device for erecting a protection net across a transmission line, and can also be used for other robots that need to walk on a transmission line, such as Figure 1 As shown, the walking mechanism 10 is on the transmission line crossing the protective net erection device, and the transmission line crossing the protective net erection device includes a shell 40, a walking mechanism 10 and a lifting ring 30. The walking mechanism 10 and the lifting ring 30 are installed on the shell 40, and the lifting ring 30 is used to fix the protective net.

[0035] The walking mechanism 10 of the embodiment of the present invention is configured with first walking wheels 122 and second walking wheels 134 staggered one above and one below, so that the walking mechanism 10 can press the transmission line from both the upper and lower directions, and the first walking wheels 122 and the second walking wheels 134 are staggered, which can increase the contact area between the walking mechanism 10 and the transmission line, thereby improving the adhesion of the walking mechanism 10. Moreover, the walking mechanism 10 is also provided with a lifting component 132, and the contact between the transmission line and the walking mechanism 10 can be made closer by adjusting the position and stroke of the lifting component 132, providing greater pressure and stability.

[0036] See also Figure 2 As shown, exemplarily, in some embodiments, the walking mechanism 10 also includes a pressure detection device 20, the pressure detection device 20 includes a pressure sensor 21 and a sensor mounting seat 22, the sensor mounting seat 22 is mounted on the mounting plate 11, and the pressure sensor 21 is mounted on the sensor mounting seat 22, the first walking wheel module 12 also includes a fixed shaft 123, a fixed seat 124 and two rotating shaft seats 125, the two rotating shaft seats 125 are installed at intervals on the mounting plate 11, and the two ends of the fixed seat 124 are respectively installed on the two rotating shaft seats 125, an axial hole 1241 is axially provided on the fixed seat 124, and a slot 1242 connected to the axial hole 1241 is radially provided on the fixed seat 124, the fixed shaft 123 is installed in the axial hole 1241, the first end of the fixed shaft 123 abuts against the pressure sensor 21, and at least one first walking wheel 122 is a passive wheel and is connected to the second end of the fixed shaft 123.

[0037] During use, when the lifting assembly 132 drives the second walking wheel 134 to press the transmission line upward, the first walking wheel 122 will also be subjected to pressure. The first walking wheel 122, which is in contact with the pressure sensor 21 through the fixed shaft 123, drives the first end of the fixed shaft 123 upward and the second end downward, applying pressure to the pressure sensor 21. When the pressure on the pressure sensor 21 reaches the preset pressure value, the indicator light is turned on to remind the walking mechanism 10 that it has been pressed against the transmission line. Through the pressure sensor 21, the pressure situation can be monitored in real time, thereby achieving precise pressing of the transmission line. Once the preset pressure value is reached, an alarm signal will be issued to ensure the safe operation of the transmission line.

[0038] It can be understood that if the lifting assembly 132 is an automatic lifting structure, when the pressure on the pressure sensor 21 reaches a preset pressure value, the lifting assembly 132 stops operating.

[0039] Furthermore, a mounting hole is provided at the second end of the fixed shaft 123, and the fixed shaft 123 is sleeved on the pressure port of the pressure sensor 21 through the mounting hole, ensuring that the connection between the fixed shaft 123 and the pressure sensor 21 is firm and reliable, so that the pressure sensor 21 can accurately sense the pressure from the first walking wheel 122, thereby realizing accurate monitoring and control of the clamping process.

[0040] Furthermore, a recessed portion is provided at the second end of the fixed shaft 123, which abuts against the outer shell of the pressure sensor 21, thereby providing a more rigid connection and effectively preventing the connection between the fixed shaft 123 and the pressure sensor 21 from loosening or failing due to vibration or external force during operation.

[0041] In this embodiment, the first drive assembly and the pressure detection device 20 are arranged on the same side of the mounting plate 11, and the second drive assembly and the lifting assembly 132 are arranged on the other side of the mounting plate 11, making the overall structure of the walking mechanism 10 more compact.

[0042] See also Figure 3 As shown, exemplarily, in some embodiments, three first walking wheels 122 are provided, the middle first walking wheel 122 is in contact with the pressure sensor 21, the first walking wheels 122 on both sides are respectively connected to the first drive assembly, and two second walking wheels 134 are provided, and the two second walking wheels 134 are respectively connected to the second drive assembly.

[0043] Furthermore, the first drive assembly includes two first drive motors 121, which are respectively installed on the mounting plate 11 and are respectively connected one-to-one with the first walking wheels 122 on both sides. The second drive assembly includes two second drive motors 133, which are respectively installed on the movable plate 131 and are respectively connected one-to-one with the two second walking wheels 134.

[0044] It can be understood that the first walking wheel 122 can be installed on the mounting plate 11 through a bearing, or it can be directly connected to the output end of the first drive motor 121, and the second walking wheel 134 can be installed on the movable plate 131 through a bearing, or it can be directly connected to the output end of the second drive motor 133.

[0045] It is understandable that in other embodiments, the two first running wheels 122 may be synchronously driven to rotate by a first driving motor 121 . Similarly, the two second running wheels 134 may be synchronously driven to rotate by a second driving motor 133 .

[0046] See also Figure 3-Figure 5 As shown, for example, in some embodiments, the lifting assembly 132 includes a rotatable screw rod 1321, a nut 1322, a nut mounting seat 1323, a first connecting rod 1324, a second connecting rod 1325, a connecting seat 1326 and a handle 1327, and two nuts 1322 and two nut mounting seats 1323 are provided. The two nuts 1322 are mounted on the two nut mounting seats 1323 in a one-to-one correspondence, and the two nuts 1322 are respectively provided at both ends of the screw rod 1321, and the first end of the first connecting rod 1324 is connected to the axis of any nut mounting seat 1323 of the nut 1322. The first end of the second connecting rod 1325 is axially connected to another nut mounting seat 1323, the second end of the first connecting rod 1324 and the second end of the second connecting rod 1325 are respectively axially connected to the connecting seat 1326, the connecting seat 1326 is connected to the movable plate 131, and the handle 1327 is connected to one end of the screw rod 1321. The lifting movement is realized by the connecting rod. During the lifting process, the swing of the connecting rod can reduce sudden starts and stops and vibrations, making the lifting process smoother; and different lifting amplitudes can be achieved by adjusting the length and angle of the connecting rod, which is simple to operate and has a wide adjustment range.

[0047] When the second running wheel 134 needs to be driven to move closer to the first running wheel 122, the handle 1327 is rotated to rotate the screw rod 1321 clockwise, thereby causing the two nuts 1322 to move toward each other, driving the first connecting rod 1324 and the second connecting rod 1325 to swing, causing the connecting seat 1326 to rise, thereby driving the second running wheel 134 to move closer to the first running wheel 122. When the second running wheel 134 needs to be driven to move away from the first running wheel 122, the handle 1327 is rotated to rotate the screw rod 1321 counterclockwise, thereby causing the two nuts 1322 to move away from each other, driving the first connecting rod 1324 and the second connecting rod 1325 to swing, causing the connecting seat 1326 to descend, thereby driving the second running wheel 134 to move away from the first running wheel 122.

[0048] Furthermore, the lifting assembly 132 also includes two receiving plates 1328 that are laterally spaced apart and arranged on the mounting plate 11. The two ends of the screw rod 1321 are respectively rotatably mounted on the two receiving plates 1328. By setting the receiving plates 1328, the overall rigidity and stability of the lifting assembly 132 can be increased, and shaking and swaying during movement can be reduced.

[0049] Furthermore, the lifting assembly 132 also includes a first slide rail 1329 and a first slide rail seat 1330 that slides with the first slide rail 1329. There are two first slide rails 1329, and the two first slide rails 1329 are correspondingly installed on the two receiving plates 1328. There are two first slide rail seats 1330, and the two first slide rail seats 1330 are respectively arranged on the lateral sides of the movable plate 131. Through the cooperation of the first slide rail 1329 and the first slide rail seat 1330, the friction and vibration during movement can be reduced, and the smoothness and stability of the lifting assembly 132 can be improved.

[0050] It is understandable that two first slide rail seats 1330 may be provided on each side.

[0051] Furthermore, the lifting assembly 132 also includes a second slide rail 1331 (not shown) and a second slide rail seat 1332 that slides with the second slide rail 1331. The second slide rail 1331 is horizontally arranged on the mounting plate 11. Two second slide rail seats 1332 are provided. The two second slide rail seats 1332 are correspondingly installed on two nut mounting seats 1323. Through the cooperation between the second slide rail 1331 and the second slide rail seat 1332, friction and vibration during movement can be reduced, and the smoothness and stability of the lifting assembly 132 can be improved.

[0052] Furthermore, the second walking wheel module 13 also includes a baffle 135 provided between the movable plate 131 and the mounting plate 11, the baffle 135 includes a vertical portion 1351, a first connecting leg 1352, a second connecting leg 1353 and a bent portion 1354, the first connecting leg 1352 and the second connecting leg 1353 are respectively provided on both sides of the vertical portion 1351, and the first connecting leg 1352 and the second connecting leg 1353 are extended from the upper edge of the vertical portion 1351 toward the direction close to the mounting plate 11, the first connecting leg 1352 and the second connecting leg 1353 are respectively provided on both sides of the vertical portion 1351. It is arranged in an L-shape, with the first connecting leg 1352 and the second connecting leg 1353 respectively connected to the mounting plate 11, and the bent portion 1354 extends from the lower edge of the vertical portion 1351 toward the mounting plate 11, and the bent portion 1354 is connected to the mounting plate 11. The lifting assembly 132 is arranged between the vertical portion 1351 and the mounting plate 11, and the baffle 135 can provide additional structural support between the movable plate 131 and the mounting plate 11, thereby increasing the stability and structural strength of the second walking wheel module 13, especially playing a protective role when subjected to external impact or vibration.
