[0051] Figures 1 to 11As shown, the present invention provides an automatic plug-in and pull-out device 100 for a thin oil lubrication pipeline of a support roller, comprising an operation side pipeline plug-in and pull-out structure 1 and a transmission side pipeline plug-in and pull-out structure 2, wherein the operation side pipeline plug-in and pull-out structure 1 comprises a first pipe clamp structure 11 and a first machine pipeline end head 12, wherein the first pipe clamp structure 11 can slide horizontally in a direction perpendicular to the central axis of the support roller 9, the first machine pipeline end head 12 can be slidably sleeved in the first pipe clamp structure 11 up and down and can move horizontally therewith, and the first end of the first machine pipeline end head 12 can be inserted into the operation side lubrication pipeline 11 and connected to the transmission side lubrication pipeline 11. The transmission side pipeline plug-in structure 2 comprises a second pipe clamp structure 21 and a second pipe end head 22 on the machine, and the second pipe end head 22 on the machine can be slidably mounted in the second pipe clamp structure 21 up and down, and the first end of the second pipe end head 22 on the machine can be inserted into the transmission side lubrication pipeline or disconnected by unplugging the transmission side lubrication pipeline, and the second end of the second pipe end head 22 on the machine can be connected to the lubrication pipeline 92 on the machine.

[0052] like Figure 1 As shown, the operating side lubrication pipeline 91 includes an operating side oil inlet pipe 911 and an operating side oil return pipe 912, which are respectively arranged on the operating side of the upper support roller and the lower support roller (the frame side perpendicular to the roller axis), and the operating side pipeline plug-in structure 1 is respectively arranged on the frame corresponding to the operating side of the upper support roller 901 and the lower support roller 902. The operating sides of the upper support roller and the lower support roller are respectively provided with one operating side oil inlet pipe and two operating side oil return pipes. The number of the operating side pipeline plug-in structures 1 is 6, which are respectively used to realize the automatic plug-in and pull-out of the on-machine lubrication pipeline 92 and each operating side oil inlet pipe and operating side oil return pipe; as shown Figure 2 As shown, the transmission side lubrication pipeline includes a transmission side oil inlet pipe and a transmission side oil return pipe, which are respectively arranged on the transmission side of the upper support roller and the lower support roller (a certain position in the axial direction of the roller), and the transmission side pipeline plug-in structure 2 is respectively arranged on the frame corresponding to the transmission side of the upper support roller 901 and the lower support roller 902. One transmission side oil inlet pipe and two transmission side oil return pipes are respectively arranged on the transmission side of the upper support roller and the lower support roller. The number of the transmission side pipeline plug-in structures 2 is 6, which are respectively used to realize the automatic plug-in and pull-out of the on-machine lubrication pipeline 92 and each transmission side oil inlet pipe and transmission side oil return pipe.

[0053] The six-high mill rolls need to be ground within a certain range when in use, and the height position of the support roll 9 varies with the different roll diameter parameters. However, the height position is fixed when the support roll 9 is replaced. The automatic plug-in and pull-out device is designed to select the replacement position of the support roll as the initial insertion position. During operation, the on-board lubrication pipeline 92 can move up and down in the first pipe clamp structure 11 and the second pipe clamp structure 21.

[0054] When the support roller 9 is replaced, the operation side pipeline plug-in structure 1 disconnects the operation side lubrication pipeline 91 and the machine lubrication pipeline 92, and the roller changing device (existing technology) pulls the support roller out from the operation side. Under the axial force of the support roller during movement, the transmission side lubrication pipeline and the machine lubrication pipeline 92 are automatically disconnected. On the contrary, after the support roller is pushed into place from the operation side, the transmission side lubrication pipeline and the machine lubrication pipeline 92 are automatically inserted, and the operation side pipeline plug-in structure 1 inserts the machine lubrication pipeline 92 into the operation side lubrication pipeline 91.

[0055] The automatic plugging and unplugging device for the thin oil lubrication pipeline of the support roller of the present invention realizes the automatic plugging and unplugging of the operating side lubrication pipeline and the transmission side lubrication pipeline with the on-machine lubrication pipeline through the operating side pipeline plugging and unplugging structure and the transmission side pipeline plugging and unplugging structure, thereby eliminating manual operation, reducing the manual operation rate, saving the time for replacing the support roller, and effectively avoiding the danger of manual climbing up and down in the oily mud environment; the present invention realizes the automation of replacing the support roller, improves production efficiency, increases the net working time, and realizes the automation of the unit.

[0056] Further, if Figure 3 , Figure 8 As shown, the operating side pipeline plug-in structure 1 also includes a first roller pipeline end head 13, the first end of the first roller pipeline end head 13 is connected to the operating side lubrication pipeline 91, and the first end of the first machine pipeline end head 12 can be plugged in and out of the second end of the first roller pipeline end head 13; the transmission side pipeline plug-in structure 2 also includes a second roller pipeline end head 23, the first end of the second roller pipeline end head 23 is connected to the transmission side lubrication pipeline, and the first end of the second machine pipeline end head 22 can be plugged in and out of the second end of the second roller pipeline end head 23.

[0057] Further, if Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, the first pipe clamp structure 11 includes a first fixed clamp plate 111, on which a through first end movable groove 1111 is arranged, and the first on-machine pipeline end 12 can be slidably sleeved in the first end movable groove 1111 up and down; a vertical first adjustment spring 112 is arranged at the bottom of the first end movable groove 1111, and the first adjustment spring 112 can adjust the height of the first on-machine pipeline end 12 from the bottom; and side positioning structures 113 are arranged on both sides of the first end movable groove 1111, which can axially fix the first on-machine pipeline end 12 from the side.

[0058] Further, if Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7As shown, the side positioning structure 113 includes micro-swinging clamps 1131 located in the first end movable groove 1111 and arranged in pairs, the two micro-swinging clamps 1131 are symmetrically arranged about the central axis of the first on-machine pipeline end 12, each micro-swinging clamp 1131 can axially fix the first on-machine pipeline end 12, and each micro-swinging clamp 1131 can extend and retract radially along the first on-machine pipeline end 12.

[0059] Further, if Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, first sliding grooves are respectively arranged on the two side surfaces of the first fixed clamping plate 111 at positions corresponding to each micro-swing clamping plate 1131, and a first tightening screw 1132 is respectively inserted in each first sliding groove. The first end of each first tightening screw 1132 is connected to each micro-swing clamping plate 1131, and a second adjustment spring 1133 is sleeved between the second end of each first tightening screw 1132 and the side surface of the first fixed clamping plate 111. Each second adjustment spring 1133 can adjust the micro-swing clamping plate 1131 from the side so that it can be radially extended and retracted along the first on-machine pipeline end 12. The micro-swinging clamp 1131 and the first fixed clamp 111 are connected by the first tightening screws 1132 on the left and right sides, and a second adjustment spring 1133 is sleeved between each first tightening screw 1132 and the first fixed clamp 111. This design allows the first machine pipeline end 12 and the micro-swinging clamp 1131 to have a certain angular displacement compensation as a whole, thereby satisfying the error of the first roller pipeline end 13 installed on the supporting roller in the angular displacement direction.

[0060] Furthermore, the side of each micro-swinging clamping plate 1131 close to the first fixed clamping plate 111 is provided with an outwardly convex arc surface, and the two inner side surfaces of the first fixed clamping plate 111 are provided with inwardly concave arc grooves, and the arc surface can be clamped in the arc groove. The fitting surface between the micro-swinging clamping plate 1131 and the first fixed clamping plate 111 is designed as an arc surface, which can withstand a certain axial force and meet the requirement that the first pipe clamping structure 11 drives the first on-machine pipeline end 12 to move in the axial direction.

The first adjustment spring 112 is arranged at the lower end of the first fixed clamping plate 111, so that the height of the first machine pipeline end 12 can be adjusted, which meets the requirement of adjusting the height of the first roller pipeline end 13 caused by the height direction error of the operating side lubrication pipeline 91 of the support roller end, and meets the requirement of aligning the first machine pipeline end 12 and the first roller pipeline end 13 in the height direction.

[0062] Further, if Figure 3 , Figure 4 As shown, the first pipe clamp structure 11 is connected to a translation driving structure 14, and the first pipe clamp structure 11 can move horizontally under the drive of the translation driving structure 14.

[0067] Further, if Figure 5 , Fig.10 As shown, a first convex ring 123 is arranged on the outer wall of the first end of the first joint body 121, and the first end of the annular retaining ring 122 is axially pressed against the first convex ring 123, and a first locking nut 124 is sleeved on the second end of the annular retaining ring 122 on the first joint body 121, and a first centering sleeve 125 is sleeved in the first end of the first joint body 121, and a centering cone surface 1251 is arranged on the inner wall of the first centering sleeve 125 from the end inward, and the centering cone surface 1251 facilitates the smooth insertion of the pipeline end 13 on the first roller; a first step portion 1211 is arranged in the first joint body 121, and a first sealing ring 126 is axially pressed against the first centering sleeve 125 and the first step portion 1211.

[0071] Further, if Figure 5 , Fig.11 As shown, a second convex ring 133 with an increased diameter is provided on the outer wall of the second joint body 131, and a shoulder retaining ring 134 is provided on the outer wall of the second joint body 131 at intervals from the second convex ring 133. The adapter sleeve 132 can slide between the second convex ring 133 and the shoulder retaining ring 134. A joint spring 135 is sleeved between the adapter sleeve 132 and the second convex ring 133. Under the external force of the joint spring 135, the adapter sleeve 132 is tightly attached to the first joint body 121, thereby ensuring the follow-up performance of the adapter sleeve 132 during the insertion or removal of the pipeline end 13 on the first roller and the pipeline end 12 on the first machine, and a certain axial force is generated between the adapter sleeve 132 and the pipeline end 12 on the first machine, which plays a stabilizing role.

[0072] When the first machine pipeline end 12 is inserted into the first roller pipeline end 13, the joint spring 135 is compressed, and the adapter sleeve 132 is pressed against the first machine pipeline end 12 by the pressing force of the joint spring 135. When the first machine pipeline end 12 is pulled out from the first roller pipeline end 13, the adapter sleeve 132 on the first roller pipeline end 13 moves to the shoulder retaining ring 134 and stops under the action of the joint spring 135.

[0073] After the first machine pipeline end head 12 and the first roller pipeline end head 13 are inserted into place, the first machine pipeline end head 12 moves up and down with the first roller pipeline end head 13. After the first machine pipeline end head 12 is inserted into the first roller pipeline end head 13, there are two supporting points: the outer cone surface of the first joint body 121 and the inner cone surface of the adapter sleeve 132, and the outer wall of the second joint body 131 and the inner wall of the first centering sleeve 125. These two supporting points ensure that the first sealing ring 126 is not subjected to force during the up and down movement of the first machine pipeline end head 12 with the first roller pipeline end head 13, thereby ensuring the sealing effect.

[0074] The structure of the pipeline end head 23 on the second roller is the same as that of the pipeline end head 13 on the first roller, and its plugging and unplugging with the second pipeline end head 22 on the machine is also the same as the plugging and unplugging of the pipeline end head 13 on the first roller and the pipeline end head 12 on the first machine.

[0075] When the support roller 9 needs to be pulled out, the support roller 9 is in the support roller changing position, the translation drive structure 14 retracts, and the sliding support 15, the first pipe clamp structure 11, and the first machine pipeline end 12 are driven to move toward the outside of the frame, the first machine pipeline end 12 and the first roller pipeline end 13 of the support roller end are disengaged, and the operating side lubrication pipeline 91 and the machine lubrication pipeline 92 are automatically disengaged. The roller changing device (existing technology) pulls the support roller out from the operating side. Under the action of the axial force when the support roller moves, the second machine pipeline end 22 and the second roller pipeline end 23 of the support roller end are disengaged, and the transmission side lubrication pipeline and the machine lubrication pipeline 92 are automatically disengaged.

[0076] When the support roller 9 is replaced, the support roller 9 is pushed in from the operating side. The positions of the first pipe clamp structure 11 and the first machine pipeline end head 12 coincide with the pushed position of the first roller pipeline end head 13. As the support roller is pushed in place, the second roller pipeline end head 23 is inserted into the second machine pipeline end head 22. The translation drive structure 14 extends to drive the sliding support 15, the first pipe clamp structure 11, and the first machine pipeline end head 12 to move toward the inside of the frame, and the first roller pipeline end head 13 is inserted into the first machine pipeline end head 12. At this time, the support roller moves up and down in the frame, the first roller pipeline end head 13 drives the first machine pipeline end head 12 to move up and down in the first pipe clamp structure 11, and the second roller pipeline end head 23 drives the second machine pipeline end head 22 to move up and down in the second pipe clamp structure 21.

[0077] After the first roller pipeline end 13 is inserted into the first machine pipeline end 12 and the second roller pipeline end 23 is inserted into the second machine pipeline end 22, when the first roller pipeline end 13 is slightly lower than the first machine pipeline end 12, the first machine pipeline end 12 compresses the first adjustment spring 112 under the action of the first roller pipeline end 13, so that the first machine pipeline end 12 moves downward accordingly; when the second roller pipeline end 23 is slightly lower than the second machine pipeline end 22, the second machine pipeline end 22 compresses the first adjustment spring 112 under the action of the second roller pipeline end 23, so that the second machine pipeline end 22 moves downward accordingly. And vice versa.

[0078] As described above, the automatic plugging and unplugging device for the thin oil lubrication pipeline of the support roller provided by the present invention has the following beneficial effects:

[0079] The automatic plugging and unplugging device for the thin oil lubrication pipeline of the support roller of the present invention realizes the automatic plugging and unplugging of the operating side lubrication pipeline and the transmission side lubrication pipeline with the on-machine lubrication pipeline through the operating side pipeline plugging and unplugging structure and the transmission side pipeline plugging and unplugging structure, thereby eliminating manual operation, reducing the manual operation rate, saving the time for replacing the support roller, and effectively avoiding the danger of manual climbing up and down in the oily mud environment; the present invention realizes the automation of replacing the support roller, improves production efficiency, increases the net working time, and realizes the automation of the unit.
