[0021] In order to enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.
[0022] Refer to Figures 1-5 , a subway segment turning machine, including symmetrically arranged first support plates 1. A circular second through groove 111 is arranged on the side surface of the first support plate 1. A rotating ring 4 is arranged in the second through groove 111. An annular groove 411 is formed on the surface of the rotating ring 4. The annular groove 411 is rotatably arranged in the circular second through groove 111, enabling the rotating ring 4 to rotate more stably in the second through groove 111.
[0023] Refer to Figures 1-2 , a plurality of tooth blocks 44 are fixedly arranged in an annular shape on the inner ring of the rotating ring 4. The tooth blocks 44 are engaged with the gear 22. By driving the rotation of the gear 22 by the second motor 21, the rotation of the rotating ring 4 is driven.
[0024] Refer to Figure 2 , an arc-shaped support plate 41 is fixedly arranged on the inner side surface of the rotating ring 4. The arc-shaped support plate 41 can be used to place subway segments, and the distance between the two rotating rings 4 corresponds to the width of the subway segment, facilitating the placement of the subway segment on the surfaces of the two arc-shaped support plates 41.
[0025] Refer to Figure 1 , a bracket 2 is fixedly arranged on the outer side surface of the first support plate 1. A second motor 21 is fixedly arranged on the side surface of the bracket 2. A gear 22 is fixedly arranged on the surface of the output shaft of the second motor 21.
[0026] Refer to Figures 1-3, symmetrically fixed on the surface of the second arc-shaped support plate 41 is a support frame 42, which can prevent the placed subway segment from slipping. Rotatably arranged in the support frame 42 is a second lead screw 421. Fixed on the upper end face of the support frame 42 is a third motor 424, and the output shaft of the third motor 424 is fixed to one end of the second lead screw 421. Threaded on the surface of the second lead screw 421 is a first slider 422, and fixed to the lower surface of the first slider 422 is a first rubber block 423, which is used to prevent the surface of the subway segment from being damaged by the pressure when the first slider 422 descends.
[0027] After placing the subway segment on the surface of the second arc-shaped support plate 41, drive the rotation of the second lead screw 421 through the third motor 424, so that the first slider 422 drives the first rubber block 423 to press and fix the arc surface of the subway segment, avoiding the dropping or displacement of the subway segment when the subway segment is flipped.
[0028] Reference Figure 5 , symmetrically opened on the side of the first support plate 1 close to the bracket 2 are first square through grooves 11. Slidably arranged in the through grooves 11 is a sliding block 3. On the side of the sliding block 3 are opened a larger groove 31 and a smaller groove 32. Rotatably arranged in the groove 31 is a third lead screw 34, and fixed in the groove 32 is a fourth motor 33.
[0029] Reference Figure 1 , the output shaft of the fourth motor 33 is fixed to one end of the third lead screw 34. Threaded on the surface of the third lead screw 34 is a second slider 35, and the second slider 35 is slidably arranged in the groove 31. Fixed to the upper surface of the second slider 35 is a second rubber block 36. Drive the rotation of the third lead screw 34 through the fourth motor 33, so that the third lead screw 34 drives the second slider 35 to slide up and down in the groove 31.
[0030] Reference Figure 1 , rotatably arranged at a position near the bottom end on the outer side of the first support plate 1 is a first bidirectional lead screw 12. The first bidirectional lead screw 12 passes through the two first through grooves 11 and is in threaded cooperation with the two sliding blocks 3. Fixed on the outer side of the first support plate 1 is a first motor 13. Drive the rotation of the first bidirectional lead screw 12 through the first motor 13, and then make the two sliding blocks 3 move relative to each other in the first through grooves 11.
[0031] Further, after the subway segment is placed and fixed, the rotation of the gear 22 is driven by the second motor 21, thereby driving the rotation of the rotating ring 4. Then, the subway segment can be driven to rotate by the arc-shaped support plate II 41. After the subway segment rotates 180 degrees, there is still a certain distance between the subway segment and the ground at this time. Then, the first bidirectional lead screw 12 is driven by the first motor 13 to move the two sliding blocks 3 to a position close to the subway segment. At this time, the second slider 35 is located at the lower end of the second groove 31. When the sliding block 3 approaches and moves to the lower surface of the subway segment, the rotation of the third lead screw 34 is driven by the fourth motor 33, and the second slider 35 rises, so that the second rubber block 36 contacts the lower surface of the subway segment and supports it. Then, the fixation of the subway segment by the first slider 422 is released, and the third lead screw 34 drives the second slider 35 to descend. Then, the subway segment can be stably placed on the bottom surface, thus completing the turning over.
