Problems solved by technology

[0003] The mud-water shield machine stabilizes the excavation surface by pressurizing muddy water or mud. There is a sealed partition behind the cutterhead, and a mud-water chamber is formed between the excavation surface, which is filled with mud, and the excavated soil material is mixed with the mud. The mud pump is transported to the separation plant outside the tunnel, and the mud is reused after separation. The existing mud chamber has limited load-bearing capacity to the outside world due to its simple mechanism. Therefore, a supporting mud chamber with good load-bearing capacity for shield machines is researched. seems necessary

Embodiment 1

[0021] refer to Figure 1-2 , a support mud for a shield machine with good bearing capacity, comprising a shield machine main body 1, a plurality of slide blocks 14 slidingly connected to the inner wall of the shield machine main body 1, and a rotating ring 13 fixedly connected to the outer wall of the other end of the slide block 14, the rotating ring 13 The two ends of the inner wall are fixedly connected with the horizontal flexible board 3, the other end of the horizontal flexible board 3 is fixedly connected with the central block 11, the top and bottom of the central block 11 are provided with vertical support mechanisms, and the two ends of the horizontal flexible board 3 are fixedly connected with Connecting rod 19, the other end of connecting rod 19 is fixedly connected with connecting block 20, and the inner wall of rotating ring 13 is fixedly connected with cross bar 16, and connecting block 20 is fixedly connected with cross bar 16, can be rotated by setting the cro...

Embodiment 2

[0027] refer to Figure 2-3 , a support mud for a shield machine with good bearing capacity, the inner wall of the central block 11 is set to be hollow, the inner wall of the central block 11 is fixedly connected with a rubber ring 12, the outer wall of the rubber ring 12 is fixedly connected with a plurality of springs 22, and the other end of the spring 22 is connected to the The horizontal flexible board 3 is fixedly connected.

[0028] When in use, the central block 11 is set to be hollow, and the spring 22 is used to connect and fix between the central block 11 and the lateral soft board 3, so that the lateral direction of the device has elastic buffering capacity, and further improves the bearing stability. There are rubber rings 12, which can further improve the elastic buffer capacity and further improve the load-bearing stability.

Abstract

The invention discloses supporting mud with good bearing capacity for a shield tunneling machine. The supporting mud with the good bearing capacity comprises a shield tunneling machine body, a plurality of sliding blocks are slidably connected to the inner wall of the shield tunneling machine body, a rotating ring is fixedly connected to the outer walls of the other ends of the sliding blocks, transverse soft plates are fixedly connected to the two ends of the inner wall of the rotating ring, a center block is fixedly connected to the other end of each transverse soft plate, vertical supporting mechanisms are arranged at the tops and the bottoms of the center blocks correspondingly, and a connecting rod is fixedly connected between the two ends of each transverse soft plate. The interior of the rotating ring can be basically transversely supported by arranging a transverse rod in the rotating ring, and the center blocks and the inner wall of the rotating ring are fixedly connected by arranging the transverse soft plates at the top and the bottom of the transverse rod, so that the purpose of transverse multi-stage supporting is achieved; the transverse soft plates and the transverse rod are fixedly connected through the connecting rods and a connecting block, so that the integrity of a transverse supporting mechanism is further improved, and the purpose of high bearing capacity is achieved in cooperation with the vertical supporting mechanisms.

Description

technical field [0001] The invention relates to the technical field of shield machines, in particular to a support mud for shield machines with good bearing capacity.
