DETAILED DESCRIPTION

[0048] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by a person of ordinary skill in the art without creative work are within the protection scope of the present application.

[0049] Please refer to Figures 1-6 In the embodiments of the present application, the rigid contact net abnormal wear automatic polishing equipment includes displacement module one 100, displacement module two 200 and two polishing modules 300. The displacement module one 100 and the displacement module two 200 are of the same structure. The polishing module 300 includes a fixed frame 310 and a sliding frame 320. The sliding frame 320 is provided with a polishing head 330 and a power frame 350 at the top. The power frame 350 is fixedly connected with a power motor 351 inside. The power motor 351 is drivingly connected with a transmission shaft 352 fixedly connected with the polishing head 330 at the output end. The transmission shaft 352 is rotatably connected with the inner side surface of the sliding frame 320. In this way, the sliding frame 320 can support the polishing head 330 through the transmission shaft 352. The displacement module one 100 is provided with two cameras. The two polishing modules 300 are arranged on the displacement module two 200. The displacement module one 100 and the displacement module two 200 are both provided with a plurality of walking wheels 400 and a plurality of limiting wheels 500 inside. The camera and the polishing module 300 are both corresponding to the adjacent two walking wheels 400. The fixed frame 310 is fixedly connected with an electric telescopic rod 311 inside. The electric telescopic rod 311 is drivingly connected with an extrusion plate 312 slidingly connected with the sliding frame 320 at the output end. The extrusion plate 312 is fixedly connected with a reset spring 313 fixedly connected with the sliding frame 320. The reset spring 313 is fixedly connected on the top surface of the extrusion plate 312. The reset spring 313 is fixedly connected on the inner top surface of the sliding frame 320. The reset spring 313 can support the sliding frame 320. The electric telescopic rod 311 is located inside the fixed frame 310 and the sliding frame 320. The sliding frame 320 is slidingly connected on the inner side surface of the fixed frame 310.

[0050] Specifically, displacement module 100 and displacement module 200 can be connected to the busbar, with the bottom side of the traveling wheel 400 resting against the busbar and the top side of the limiting wheel 500 at the top of the busbar. Thus, displacement module 100 is connected to the busbar via the traveling wheel 400 and the limiting wheel 500. The traveling wheel 400 rolls on the busbar, allowing displacement module 100 and displacement module 200 to move forward along the rigid contact wire. Displacement module 100 can drive the camera forward, and displacement module 200 can drive the grinding module 300 forward. The camera can capture images of the contact wire, and the captured images can be analyzed to determine the wear condition of the contact wire. A laser sensor can be installed to detect wear. After determining the location of abnormal wear on the contact wire, displacement module 100 can drive the camera to continue moving forward to continue detecting the contact wire, and displacement module 200 can drive the grinding module 300. The grinding module 300 moves to the worn position, and the electric telescopic rod 311 moves the pressing plate 312 upward a certain distance. The pressing plate 312 supports the sliding frame 320 through the return spring 313, so that the grinding head 330 is pressed against the contact line. Then, the power motor 351 drives the transmission shaft 352 to rotate, and the transmission shaft 352 drives the grinding head 330 to rotate, so that the grinding head 330 grinds the contact line. During grinding, the return spring 313 can keep the grinding head 330 as close to the contact line as possible, which helps to ensure the grinding effect of the contact line. While the grinding module 300 is grinding the contact line, the displacement module 100 can drive the camera to continue to detect the contact line, so that the wear position can be determined relatively quickly. After the grinding module 300 finishes grinding a wear position, the displacement module 200 can drive the grinding module 300 to the next wear position relatively quickly, which helps to improve maintenance efficiency.

[0067] Embodiment two

[0068] On the basis of embodiment one, as Figures 6-8As shown, in the embodiment, the top surface of the connecting base 111 is fixedly connected with a positioning base 113;

[0069] The positioning mechanism 120 comprises a connecting plate 121 and an arc-shaped plate 122.

[0070] The connecting plate 121 is fixedly connected at the bottom end of the two adjacent fixed rods 132, and the arc-shaped plate 122 is fixedly connected at the bottom of the connecting plate 121. The arc-shaped plate 122 is rotatably connected with the adjacent positioning base 113.

[0071] The connecting base 111 is internally provided with an adjusting motor 115. The output end of the adjusting motor 115 is drivingly connected with an adjusting rod 116 which is rotatably connected with the positioning base 113. The adjusting rod 116 is fixedly sleeved with an adjusting gear 117. The arc-shaped plate 122 is fixedly connected with an arc toothed plate 123 which is in mesh with the adjusting gear 117. The arc toothed plate 123 is rotatably connected with the inner side surface of the positioning base 113. The adjusting rod 116 is rotatably connected with the inner side surface of the connecting base 111. The arc-shaped plate 122 and the arc toothed plate 123 are rotatably connected inside the positioning base 113, so as to connect the connecting plate 121 with the positioning base 113, and further connect the connecting mechanism 110 with the positioning mechanism 120.

[0072] In the specific implementation, after the displacement module 100 drives the camera to move and the contact line detection is completed, the displacement module 100 can drive the camera to move towards the displacement module 200. After the displacement module 100 and the displacement module 200 are abutted, the adjusting motor 115 can drive the adjusting rod 116 to rotate, and the adjusting rod 116 can drive the adjusting gear 117 to rotate. Since the positioning mechanism 120 is connected with the adjusting mechanism 130, and the adjusting mechanism 130 is connected with the busbar, the adjusting gear 117 can roll along the arc toothed plate 123, so as to rotate the positioning base 113 relative to the arc-shaped plate 122. Thus, the connecting mechanism 110 can rotate on the positioning mechanism 120, so as to rotate the connecting mechanism 110 of the displacement module 100 to the bottom of the positioning mechanism 120 of the displacement module 200, and rotate the connecting mechanism 110 of the displacement module 200 to the bottom of the positioning mechanism 120 of the displacement module 100. The camera is adjusted to the bottom of the positioning mechanism 120 of the displacement module 200, and the polishing module 300 is adjusted to the bottom of the positioning mechanism 120 of the displacement module 100. The polishing module 300 is located in front, and the camera is located in back. At this time, the adjusting mechanism 130 of the displacement module 100 can continue to drive the polishing module 300 to move forward, so as to polish the next wear position. The adjusting mechanism 130 of the displacement module 200 can drive the camera to move backward, so as to detect the polished area again, which is beneficial to ensure the polishing effect.

[0073] As shown in the drawings, Figures 6-8As shown, in the embodiment, the positioning seat 113 is provided with four plug-in grooves 114, and conductive sheets are embedded in the plug-in grooves 114. The arc-shaped plates 122 are fixedly connected with two conductive strips 124 on the side surfaces, the conductive strips 124 on adjacent two arc-shaped plates 122 are staggered with each other, the conductive strips 124 are slidably connected with the inner side surfaces of the adjacent plug-in grooves 114, and the conductive strips 124 are in contact with the adjacent conductive sheets.

[0074] In the embodiment, the power supply structure is arranged inside the connecting seat 111, the power supply structure is connected with the conductive sheets, and the driving motor one 134, the driving motor two 135 and the double-shaft motor 143 are connected with the conductive strips 124. When the conductive strips 124 are in contact with the adjacent conductive sheets, the power supply structure can supply power to the driving motor one 134, the driving motor two 135 and the double-shaft motor 143 through the conductive strips 124 and the conductive sheets. By staggering the conductive strips 124 on adjacent two arc-shaped plates 122 up and down, when the connecting mechanism 110 of the displacement module one 100 is adjusted to the bottom of the positioning mechanism 120 of the displacement module two 200, the conductive strips 124 of adjacent two arc-shaped plates 122 can abut on different conductive sheets.
