[0024] As shown in Figures 1-5 , an efficient vertical mill for cement production, comprising a vertical mill body 1 and an internally arranged known roller shaft 3, the roller shaft 3 is sequentially provided with a hub 4, an inner roller sleeve 5 and an outer roller sleeve 2 from inside to outside, the end face of the inner roller sleeve 5 is provided with an annular groove 20, the two side arc surfaces of the annular groove 20 are both provided with a plurality of insert pieces 6 which are arranged in an annular array around the hub 4, a spring rod 7 is connected between the insert piece 6 and the inner wall of the annular groove 20, and the inner side surface of the outer roller sleeve 2 and the outer side surface of the hub 4 are both provided with an insertion hole 8 corresponding to the position of each insert piece 6, the insertion hole 8 is inserted with the insert piece 6 at the corresponding position, and Figure 4 , at this time, the spring rod 7 is in an elastic elongation state, and at this time, the insert piece 6 is separated from the adjacent insertion hole 8, so that personnel can directly remove the inner roller sleeve 5 and the outer roller sleeve 2, and under normal circumstances, the spring rod 7 is elastically contracted and reset to realize the insertion of the insert piece 6 into the corresponding insertion hole 8, so that the relative position of the hub 4, the inner roller sleeve 5 and the outer roller sleeve 2 can be fixed, two insert pieces 6 distributed along the radius direction of the inner roller sleeve 5 are provided with a threading pipe 9 fixedly installed in the annular groove 20, the center line of the threading pipe 9 is arranged in parallel with the center line of the inner roller sleeve 5, the threading pipe 9 is provided with two strands of traction lines 10, one end of the two strands of traction lines 10 respectively penetrates the threading pipe 9 and is connected with the two insert pieces 6, and the other end of the two strands of traction lines 10 is fixedly installed with a sliding seat 17 inserted into the inner part of the annular groove 20, the annular groove 20 is provided with a traction mechanism for pulling the sliding seat 17, the traction mechanism generates a pulling force on all the sliding seats 17, and under the action of the pulling connection of the corresponding traction line 10, the corresponding insert piece 6 can drive the spring rod 7 to be elastically elongated and separated from the insertion hole 8, so that all the insert pieces 6 in the annular groove 20 can be simultaneously moved and separated from the corresponding insertion hole 8, and the inner roller sleeve 5 and the outer roller sleeve 2 can be directly removed, when the traction mechanism loses the traction effect on the sliding seat 17, the insert piece 6 can be moved into the insertion hole 8, and under the traction effect of the traction line 10, the sliding seat 17 can be moved in the direction of the threading pipe 9.

[0025] Further, the traction mechanism comprises a card 19 fixed on one side of the sliding seat 17 and a connecting ring 13 inserted into one side of the annular groove 20 close to the slot, as Figure 5As shown, the card 19 is arranged in an "F" shape, with the middle part being longer and the end away from the slide 17 being shorter. The surface of the connecting ring 13 is connected to the cross rod 18 at any position of the wire tube 9. The cross rod 18 is in the shape of a cross at one end between the two cards 19, and the two long ends of the cross-shaped part are overlapped with the middle part of the two cards 19. Referring again to Figure 5 At this time, the cross rod 18 limits the card 19 installed on the slide 17. Since the position of the connecting ring 13 is fixed, the position of the cross rod 18 is also fixed. Therefore, by overlapping the long side of the cross-shaped part of the cross rod 18 with the longer middle part of the card 19, the card 19 can be prevented from moving right with the slide 17 under the contraction of the spring rod 7, that is, the inner roller sleeve 5 and the outer roller sleeve 2 can be directly removed. By overlapping the long side of the cross-shaped part of the cross rod 18 with the longer middle part of the card 19, when the plug-in part 6 is inserted into the corresponding plug-in hole 8, the cross rod 18 is moved left through the connecting ring 13, which can pull the card 19 and the slide 17 left, and then pull the traction line 10 to move, so as to move the plug-in part 6 out of the plug-in hole 8.

[0027] Further, the guide frame 11 is hingedly connected to the push piece 12 through a torsion spring. The swing end of the side close to the wire tube 9 of the push piece 12 is arranged in a triangular shape. The right angle side of the triangular shape at one end of the push piece 12 is used to overlap with the end of the card 19 on the same guide frame 11. The end away from the wire tube 9 of the push piece 12 is arranged in an inclined surface and used to abut against the short side of the end of the cross rod 18. The end away from the wire tube 9 of the cross rod 18 is fixedly connected to the gear 14. The side surface of the connecting ring 13 is rotatably connected to the gear ring 15 engaged with the gear 14. Combined with Figure 5, the short side of the end of the card 19 is overlapped by the oblique side of the triangle end of the poking piece 12, and the short side of the end of the card 19 is overlapped by the right angle side of the triangle of the poking piece 12, so that the card 19 cannot be moved to the right, and when the sliding seat 17 needs to be moved to the right, the rotating tooth ring 15 can be rotated to rotate the cross rod 18 on the connecting ring 13 by 90 degrees, so that the cross rod 18 at the end of the cross is overlapped with the middle position of the card 19, and then the rotating screw 16 is rotated to move the connecting ring 13 to the left and drive the cross rod 18 to move to the left, until the two short sides of the cross rod 18 are moved to the oblique side of the left side of the poking piece 12 and push the elastic swinging of the poking piece 12, so that the right angle side of the triangle of the poking piece 12 is separated from the short side of the end of the card 19, and the sliding seat 17 is driven by the elastic contraction of the spring rod 7 to move the card 19 to the right, until the plug-in part 6 is inserted into the corresponding plug-in hole 8.

[0028] When the inner roller sleeve 5 and the outer roller sleeve 2 need to be disassembled, the long side at the end of the cross of the cross rod 18 is overlapped with the middle of the card 19, and the rotating screw 16 is rotated to move the connecting ring 13 to the left and drive all the cross rods 18 in the annular groove 20 to move to the left, during the movement, the long side of the cross of the cross rod 18 pushes the card 19 to move to the left, and then the sliding seat 17 is moved to the left, and the plug-in part 6 is separated from the corresponding plug-in hole 8 under the traction of the traction line 10, so that all the plug-in parts 6 in the annular groove 20 are separated from the corresponding plug-in hole 8, and the card 19 is moved to the state as shown in Figure 5 , that is, the short side of the end of the card 19 is overlapped by the oblique side of the triangle end of the poking piece 12, and the short side of the end of the card 19 is overlapped by the right angle side of the triangle of the poking piece 12, so that the card 19 cannot be moved to the right, and when the sliding seat 17 needs to be moved to the right, the rotating tooth ring 15 can be rotated to rotate the cross rod 18 on the connecting ring 13 by 90 degrees, so that the cross rod 18 at the end of the cross is overlapped with the middle position of the card 19, and then the rotating screw 16 is rotated to move the connecting ring 13 to the left and drive the cross rod 18 to move to the left, until the two short sides of the cross rod 18 are moved to the oblique side of the left side of the poking piece 12 and push the elastic swinging of the poking piece 12, so that the right angle side of the triangle of the poking piece 12 is separated from the short side of the end of the card 19, and the sliding seat 17 is driven by the elastic contraction of the spring rod 7 to move the card 19 to the right, until the plug-in part 6 is inserted into the corresponding plug-in hole 8.
