[0020] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0021] Reference Figures 1-4 A steel plate sealing brush structure for a shield machine includes a shield tail 1 and a pipe segment 2. A plurality of arc-shaped fixing blocks 3 are fixedly connected to the inner side of the shield tail 1 near the pipe segment 2. Both ends of one side of each arc-shaped fixing block 3 are fixedly connected to a plug rod 7. The circumferential surfaces of the two plug rods 7 at the same location are slidably sleeved with the same arc-shaped steel plate 4. Both ends of the arc-shaped steel plate 4 are provided with circular holes adapted to the plug rod 7. The circumferential surfaces of the two plug rods 7 at the same location are also slidably sleeved with a clamping strip 19. Both ends of each clamping strip 19 are provided with a circular hole adapted to the plug rod 7. Each card strip 19 is provided with a locking mechanism, which includes a fixed rod 6 fixedly connected to the middle part of the card strip 19 near the insertion rod 7, and a protrusion 9 is fixedly connected to the other end of the fixed rod 6. The circumferential surface of the fixed rod 6 is slidingly sleeved with an extrusion plate 10, and the middle part of the extrusion plate 10 is provided with a circular hole adapted to the fixed rod 6. The circumferential surface of the fixed rod 6 between the protrusion 9 and the extrusion plate 10 is sleeved with a spring 8. Through the setting of the spring 8, the two strip-shaped card rods 12 will not loosen with the semicircular card block 17 under natural circumstances.

[0022] In this embodiment, the locking mechanism also includes a pull rod 11 rotatably connected to the two ends of the extrusion plate 10, and the other end of each pull rod 11 is rotatably connected to a strip clamping rod 12, and each strip clamping rod 12 has a strip hole 13 in the middle. The arrangement of the strip hole 13 and the T-shaped fixing block 14 allows the strip clamping rod 12 to slide along the clamping strip 19, and each strip hole 13 is slidably connected to a T-shaped fixing block 14, and each T-shaped fixing block 14 is fixedly connected to the clamping strip 19.

[0023] In this embodiment, a clamping groove 701 is provided on the adjacent side of the two insertion rods 7 . A semicircular clamping block 17 is provided in each clamping groove 701 , and the semicircular clamping block 17 is adapted to the strip clamping rod 12 .

[0024] In this embodiment, each semicircular block 17 is rotatably connected to a threaded rod 15 on one side away from the arc-shaped steel plate 4 , and each threaded rod 15 is threadedly penetrated by the adjacent insertion rod 7 .

[0025] In this embodiment, each inserted rod 7 is fixedly provided with a screw nut that is compatible with the threaded rod 15, and the other end of each threaded rod 15 is fixedly connected to a hexagonal nut 16. Through the arrangement of the hexagonal nut 16, the threaded rod 15 and the semicircular block 17, the arc-shaped steel plate 4 can be further tightened.

The strip clamping rod 12 is controlled by pulling the U-shaped pull rod 18.

[0027] Working principle: When the curved steel plate 4 is replaced, the extrusion plate 10 is pulled by the U-shaped pull rod 18, so that the spring 8 is compressed. The two strip clamping rods 12 are retracted with each other through the setting of the pull rod 11. The outer end of the strip clamping rod 12 is separated from the semicircular clamping block 17. At this time, the clamping strip 19 can be pulled out of the insertion rod 7. At this time, the curved steel plate 4 with the steel plate sealing brush 5 can be pulled out. After the new curved steel plate 4 and the steel plate sealing brush 5 are put on the insertion rod 7, the clamping strip 19 is also put on the insertion rod 7, and the U-shaped pull rod 18 is pulled. , so that the outer ends of the two strip clamping rods 12 shrink to facilitate the engagement with the semicircular clamping block 17. After the strip clamping rod 12 is engaged with the semicircular clamping block 17, if the arc-shaped steel plate 4 is still relatively loose, the hexagonal nuts 16 at the top of the two insertion rods 7 can be rotated by using a tool to make the threaded rod 15 lower with the semicircular clamping block 17, and the strip clamping rod 12 and the clamping strip 19 are tightly pressed on the arc-shaped steel plate 4, so that the arc-shaped steel plate 4 is in close contact with the arc-shaped fixing block 3, thereby realizing the rapid replacement and maintenance of the steel plate sealing brush 5 and the arc-shaped steel plate 4.
