Technical Field

[0002] A shield machine is a tunnel boring machine that uses the shield method. The shield construction method is that the tunnel boring machine builds a tunnel shield while excavating. When the shield machine is excavating, there will be an over-excavation gap. Since the shield machine advances at a relatively slow speed, once the slurry enters the over-excavation gap, it will solidify and wrap the shield shell, thereby increasing the resistance to the shield machine's advancement and eventually trapping the shield machine and making it unable to operate normally. Therefore, installing a slurry stopping system can effectively prevent the slurry from entering the shield tail gap.

[0004] However, the existing technology is that there are pre-drilled threaded holes on the end face of the shield machine for installing the slurry stop plates. However, due to errors, the gaps between the slurry stop plates may be too large when they are arranged, and the sealing effect is not particularly good. There may be a risk of leakage. Therefore, there is an urgent need for a bulk slurry stop system in the market to solve these problems. Utility Model Content

[0024] When in use, the welding seat 13 is welded to one end of the shield tail brush base plate 2, and then the slurry stop plate 14 is installed on one side of the welding seat 13.

In this way, there will be no large gap between the slurry stop plates 14, and the slurry will not easily enter the inside of the shield body shell through the gap, thereby protecting the shield machine well.

[0025] See also Figure 1 and Figure 3 An oil channel 201 is arranged inside the shield tail brush bottom plate 2, and an oil outlet 202 is arranged at the lower end of the oil channel 201. There are several oil outlets 202, and the several oil outlets 202 are sequentially distributed at the lower end of the oil channel 201. This arrangement can facilitate oil transportation, so that the device can be conveniently lubricated and the device can work better.

[0026] See also Figure 1 and Figure 3 A bristle 6 is installed at one end of the mounting seat 5, and one end of the bristle 6 is located inside the mounting seat 5.

A fixing screw hole 1501 is arranged inside the rear mounting plate 15, and a fixing screw hole 2 1601 is arranged inside the front mounting plate 16. The structure between the welding seat 13 and the shield tail brush bottom plate 2 can be made more solid. By arranging the rear mounting plate 15 and the front mounting plate 16, there can be no large gaps when the slurry stopping plates 14 are arranged, so that slurry leakage will not occur.

[0030] See also Figure 2 A mounting screw hole 1702 is provided inside the pressure plate 17, and a limiting pressure groove 1701 corresponding to the front mounting plate 16 is provided at one end of the pressure plate 17.

[0031] Working principle: When in use, the welding seat 13 is welded to one end of the shield tail brush base plate 2, and then the slurry stop plate 14 is installed on one side of the welding seat 13, and then the slurry stop plate 14 is limited and squeezed by the pressure plate 17, and then the pressure plate 17, the slurry stop plate 14 and one end of the shield tail brush base plate 2 are installed and fixed by the cover nut 18. The slurry stop plate 14 is installed by two front mounting plates 16 on the front ends of the two rear mounting plates 15. In this way, there will be no large gaps between the slurry stop plates 14, and the slurry is not easy to enter the inside of the shield body shell through the gap. When the slurry solidifies, it will increase the resistance of the shield machine to move forward and eventually cause the shield machine to be trapped and unable to operate normally. Therefore, the slurry stop plate 14 can effectively block the slurry, thereby protecting the shield machine well.
