[0002] As a current carrier for high voltage and ultra-high voltage, conductive tubes have very strict requirements on the smoothness of the inner and outer surfaces of the product, and the surface roughness must be higher than Ra3.2. Otherwise, under high voltage and ultra-high voltage working conditions, high voltage discharge is easily caused by sharp points, and if high voltage discharge occurs, it will be devastating to the safe operation of the entire power grid.

[0003] Polishing of the outer wall of the conductive tube has important applications and significance in the field of power transmission. Polishing can significantly improve the surface quality of the outer wall of the conductive tube, improve smoothness and flatness, etc. At the same time, polishing can also optimize material properties, change the surface structure and grain size of the outer wall of the conductive tube, thereby optimizing mechanical properties, conductive properties and other characteristics. In addition, polishing can also improve processing accuracy, improve processing accuracy and consistency, and directly affect the quality and performance of the product.

[0053] At the positions of the two transverse guide rails 18 at both ends of the longitudinal rotating shaft 19, a moving roller 22 is respectively installed, and the moving roller 22 is rollingly supported on the corresponding transverse guide rail 18.

[0056] Specifically, Figure 4 , 8As shown in Figures 9 and 10, a polishing motor 11, an active driving wheel 9 and a driven driving wheel 10 are installed on the side of the mounting plate 5 facing away from the active polishing wheel 6, wherein the active driving wheel 9 is installed at the output end of the active driving wheel 9, the driven driving wheel 10 is coaxially arranged with the active polishing wheel 6, and a driving belt 110 is wound around the driven driving wheel 10 and the active driving wheel 9.

[0058] In this embodiment, the lifting mechanism is a lifting hydraulic cylinder 131. A hydraulic station 132 is provided on the side of the mobile working platform 2 facing away from the lifting hydraulic cylinder 131. Two hydraulic connection pipes 133 are connected between the lifting hydraulic cylinder 131 and the hydraulic station 132, thereby realizing the telescopic movement of the lifting hydraulic cylinder 131. An articulated seat 24 is provided at the lower end of the mounting plate 5 corresponding to the upper end of the lifting hydraulic cylinder 131. The upper end of the lifting hydraulic cylinder 131 is articulated in the articulated seat 24 through an articulated shaft 25. Similarly, an articulated seat 24 is also provided at the upper end of the mobile working platform 2 corresponding to the lower end of the lifting hydraulic cylinder 131. The lower end of the lifting hydraulic cylinder 131 is articulated with the articulated seat 24 through an articulated shaft 25.

[0059] In this way, the mounting plate 5 can be swung around the upper end of the vertical mounting frame by lifting and lowering the lifting hydraulic cylinder 131, thereby driving the active polishing wheel 6 to approach or move away from the conductive tube 16 to be polished, thereby facilitating the adjustment of the positions of the active polishing wheel 6 and the conductive tube 16 to be polished.

[0060] Preferably, Figure 5 , 6 As shown in FIGS. 7 and 9, in this embodiment, a protective plate 35 is further provided outside the active polishing wheel 6 and the driven polishing wheel 7, and a tensioning mechanism 14 is further provided between the active polishing wheel 6 and the driven polishing wheel 7. The tensioning mechanism 14 includes a tensioning plate 141, which is fixedly provided on the side of the mounting plate 5 at a position between the active polishing wheel 6 and the driven polishing wheel 7, and a tensioning cylinder 142 is provided on the tensioning plate 141. Specifically, the tensioning cylinder 142 is located between the driven polishing wheel 7 and the active polishing wheel 6, and the tensioning cylinder 142 is fixedly installed on the tensioning plate 141 through a connecting bracket 1413.

[0061] A compressed air pipe 1412 is respectively provided at both ends of the cylinder body of the tensioning cylinder 142, so as to realize the extension and retraction of the tensioning cylinder 142. The retractable end of the tensioning cylinder 142 is arranged toward the driven polishing wheel 7, and a tensioning frame 143 is provided at the retractable end of the tensioning cylinder 142, and the driven polishing wheel 7 is rotatably mounted on the tensioning frame 143 through the driven polishing rotating shaft 113.

[0062] Specifically, in this embodiment, the tensioning frame 143 includes a transverse extension plate 145 fixedly mounted on the telescopic end of the tensioning cylinder 142, and a longitudinal extension plate 144 is respectively arranged on both sides of the transverse extension plate 145. The longitudinal extension plate 144 extends toward the driven polishing shaft 113, and the spacing between the two longitudinal extension plates 144 is adapted to the transverse length of the driven polishing wheel 7. The driven polishing wheel 7 is clamped between the two longitudinal extension plates 144.

[0063] A clamping notch 146 adapted to the driven polishing shaft 113 is provided on the side of the longitudinal extension plate 144 facing the driven polishing wheel 7. The driven polishing shaft 113 is clamped in the clamping notch 146. The driven polishing wheel 7 is rotatably mounted on the driven polishing shaft 113 through the driven bearing 114. The telescopic direction of the tensioning cylinder 142 coincides with the connecting line between the active polishing shaft 112 and the driven polishing shaft 113. In this way, the tensioning frame 143 can be driven to move by the tensioning cylinder 142, and then the tensioning frame 143 can be used to drive the driven polishing shaft 113 to move, thereby adjusting the spacing between the active polishing wheel 6 and the driven polishing wheel 7, and adjusting the tightness of the polishing sandpaper belt 8. On the one hand, it is ensured that the polishing sandpaper belt 8 is always tensioned during polishing to ensure the polishing quality, and on the other hand, it is convenient to replace the polishing sandpaper belt 8.

[0064] In this embodiment, preferably, an adjustment mechanism 147 is further provided on the longitudinal extension plate 144, and the adjustment mechanism 147 includes an adjustment nut 148 provided on the longitudinal extension plate 144, and an adjustment screw 149 is connected to the inner thread of the adjustment nut 148, and the adjustment screw 149 abuts against the circumferential surface of the driven polishing shaft 113 at one end thereof facing the driven polishing shaft 113. In this way, the relative position of the adjustment screw 149 in the adjustment nut 148 can be adjusted, and the driven polishing shaft 113 can be driven to move by the adjustment screw 149, so as to further adjust the tightness of the polishing emery cloth belt 8, thereby ensuring that the polishing emery cloth belt 8 is always taut during polishing, thereby improving the accuracy of the tightness adjustment.

[0065] Preferably, in this embodiment, the adjusting nut 148 is rotatably arranged on the longitudinal extension plate 144. Specifically, an arc groove (not shown in the figure) is arranged at the position of the longitudinal extension plate 144 corresponding to the adjusting nut 148. The outer periphery of the adjusting nut 148 is cylindrically matched with the arc groove. The adjusting nut 148 is rotatably installed in the arc groove through a bearing. In addition, an arc surface 1410 matching with the circumference of the driven polishing rotating shaft 113 is arranged at one end of the adjusting screw 149 facing the driven polishing rotating shaft 113. The arc surface 1410 can increase the contact area between the adjusting screw 149 and the driven polishing rotating shaft 113, ensure reliable contact between the two, and improve stability. At the same time, the arc surface 1410 is matched with the circumference of the driven polishing rotating shaft 113 to prevent the adjusting screw 149 from rotating, thereby realizing the linear movement of the adjusting screw 149 under the rotation of the adjusting nut 148.

[0066] Of course, in other embodiments, the adjusting nut 148 can also be directly fixed on the longitudinal mounting plate 144. In this case, the end surface of the adjusting screw 149 facing the driven polishing shaft 113 is a plane, and the position of the adjusting screw 149 can be adjusted by rotating it. Figure 2 , 4 As shown in FIGS. 9 and 10 , a vertical plate is provided on each longitudinal side of the base 1, so that the interior of the base 1 forms a water receiving tray 101. A water tank 28 and a control console 27 are also provided on the mobile working platform 2, and the water tank 28 is provided at the lower end of the hydraulic station 132 to improve space utilization. During the actual polishing operation, it is necessary to spray water on the polishing part, so a water supply pump (not shown in the figure) is connected to the water tank 28, and a water supply pipe (not shown in the figure) is connected to the water supply pump. The other end of the water supply pipe extends to the mounting plate 5 and is arranged toward the part to be polished. In this way, real-time water spraying can be achieved during polishing to cool down and reduce dust, which is beneficial to environmental protection and avoids affecting the polishing quality.

[0067] At the same time, the water receiving tray 101 can be used to receive the flowing water. A water pump (not shown in the figure) is also arranged on the water receiving tray 101. The water pump is connected to the water tank 28 through a water pipe, and is used to recycle the water flowing onto the water receiving tray 101 into the water tank 28, so as to realize the recycling of water resources.

[0068] The use process of the polishing equipment of the present invention is:

[0069] First, the conductive tube 16 to be thrown is set on the supporting roller 4 at the upper end of the transverse supporting frame 3, and the end of the conductive tube 16 to be thrown with the connecting flange 17 is arranged toward the driving motor 151, and an appropriate rotating connecting tool 152 is selected to connect the universal coupling 153 and the connecting flange 17, and the rotating connecting tool 152 and the driving motor 151 are connected through the universal coupling 153, so that the driving motor 151 is used to drive the conductive tube 16 to rotate.

[0070] Contract the tensioning cylinder 142, replace the appropriate polishing abrasive cloth belt 8, and then extend the tensioning cylinder 142 so that the polishing abrasive cloth belt 8 is tensioned on the driven polishing wheel 7 and the active polishing wheel 6. At the same time, use the adjusting bolt 149 to adjust the position of the driven polishing shaft 113 and the tension of the polishing abrasive cloth belt 8.

[0071] The lifting hydraulic cylinder 131 is started to drive the active polishing wheel 6 to flip toward the conductive tube 16 to be polished until the polishing sandpaper belt 8 contacts the outer periphery of the conductive tube 16 to be polished, and the polishing motor 11 is started to polish the polishing sandpaper belt 8. At the same time, the motion motor 29 is started to use the active sprocket 30 to drive the driven sprocket 301 to rotate, thereby driving the mobile working platform 2 to move horizontally to achieve the overall polishing operation of the conductive tube 16 to be polished.

[0072] In summary, the polishing equipment of the present invention utilizes the transverse support frame 3 and the support roller 4 to stably support the conductive tube 16 to be polished. The driving mechanism 15 combined with the support roller 4 can drive the conductive tube 16 to be polished to rotate. The polishing assembly can be driven by its moving mechanism to move the polishing piece to the surface of the conductive tube 16 to be polished for polishing. At the same time, the mobile working platform 2 can drive the polishing assembly to move horizontally, and then the polishing piece can be used to complete the polishing operation of the entire conductive tube 16 to be polished. On the one hand, the labor intensity of workers is reduced, and on the other hand, the work quality can be guaranteed and the work efficiency can be improved. At the same time, the conductive tube 16 to be polished is supported as a whole on the transverse support frame 3 and only rotates, and does not need to move horizontally, which can improve the safety and reliability of the operation.
