[0002] The shield machine sealing brush, as a crucial part in the operation of the shield machine, its performance directly determines the efficiency and safety of the shield construction. Through its unique design and high-quality materials, the sealing brush establishes a solid sealing line between the tail of the shield machine and the segment, effectively preventing the leakage of mud, water, sand and other substances.

[0003] However, the steel wire frame structure of the shield machine sealing brush brings considerable challenges in actual use for disassembly and replacement. This structure is composed of multiple steel wire assemblies and complex connection points, and each assembly needs precise positioning and fixing, making the disassembly and reassembly process quite cumbersome and difficult.

[0004] More complicatedly, the shield machine usually works in narrow and challenging underground environments, which makes the operation personnel face even more arduous tasks when disassembling and replacing the sealing brush. At the same time, due to the special working environment, the operation personnel may face safety risks such as falling and electric shock when performing these tasks, which requires them to be doubly careful during operation, which may further prolong the operation time.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] Example 1

[0027] like Figures 1-4 As shown, when introducing the shield machine sealing brush of this embodiment, we can start with its components. First, this sealing brush includes a fixing clamp 1 and an upper steel frame 4, wherein the upper steel frame 4 is carefully installed in the clamping cavity of the fixing clamp 1. To further improve its performance, a lower steel frame 5 is provided at the lower end of the upper steel frame 4, and the two cooperate with each other through a specific design.

[0028] Both the upper steel frame 4 and the lower steel frame 5 are provided with mesh holes 6, and these mesh holes 6 correspond to each other. At these mesh holes 6, we installed detachable wire brushes, which enables the wire brushes to be easily replaced or repaired when needed.

[0029] To fix the wire brush, we connected the flipping extrusion plate 2 to the upper end of the fixing clip 1 through the hinge device 3. By simply rotating the flipping extrusion plate 2, we can extrude the wire brush to make it more firmly fixed on the steel frame.

[0030] The design of this wire brush is very unique. It consists of a wire brush arc part 7, a wire brush straight part 8, and an elastic part 10. The lower end of the elastic part 10 is provided with the wire brush straight part 8, and this straight part passes through the upper steel frame 4 and the lower steel frame 5 and is fixed. At the lower end of the wire brush straight part 8, we designed the wire brush arc part 7, and this part of the design greatly enhances the compressive resistance of the sealing brush.

[0031] To ensure the stable connection between the upper steel frame 4 and the lower steel frame 5, we used limit cylinders, bolts, nuts, and anti-slip gaskets, and carefully distributed them at the four corners of the steel frame.

[0032] The wire brush straight part 8, the wire brush arc part 7, and the elastic part 10 are integrally designed. Such a design not only improves the strength of the sealing brush but also makes it more durable. Among them, the wire brush straight part 8 is welded to the lower steel frame 5, and the cross-sections of these three parts present a unique "丿" - shaped design.

[0033] In addition, we added a rubber sealing gasket between the upper steel frame 4 and the fixing clip 1 to enhance the sealing effect. The flipping range of the flipping extrusion plate 2 is set from zero degree to thirty degrees to ensure the flexibility and stability of its operation; since the lower steel frame 5 is connected to the wire brush, after removing the nut at the connection of the upper steel frame 4 and the lower steel frame 5, it is convenient to take out the lower steel frame 5 and all the wire brushes for easy replacement and maintenance.

[0034] Embodiment Two

[0035] The shield machine sealing brush of this embodiment is further optimized based on Embodiment One. In addition to having all the features in Embodiment One, we also made some improvements to the design of the wire brush.

[0036] First, in the middle of the wire brush straight part 8, we added a clamping and fixing part 9. The cross-section of the clamping and fixing part 9 is designed in a "U" - shape and is welded to the wire brush straight part 8. This design enables the clamping and fixing part 9 to be bent and wound around the lower steel frame 5, thus ensuring the stability of the wire brush during use.

[0037] Secondly, at the upper end of the elastic part 10, we added a bending connecting part 11. The bending connecting part 11 is also made of bendable metal material, and by bending it, it can be wound around the upper layer steel frame 4. Such design makes the elastic part 10 have an arc, thereby further enhancing the compression resistance of the sealing brush. The sealing brush of the shield tunneling machine of the embodiment not only has higher stability and durability, but also is more flexible and convenient during use.

[0038] Disassembly process: Ensure that the shield tunneling machine is in a stopped state, and disconnect all power supply and hydraulic supply related to the sealing brush. Gently turn the turnover extrusion plate 2 to release the extrusion force on the steel wire brush. Pay attention to stability and safety during operation to avoid pinching fingers.

[0039] Using appropriate tools, remove the limiting cylinder, bolt, nut and anti-skid washer at the four corners of the connection between the upper layer steel frame 4 and the fixing clamp 1. After confirming that the connecting nut between the upper layer steel frame 4 and the lower layer steel frame 5 has been removed, carefully take out the lower layer steel frame 5 together with the steel wire brush from the upper layer steel frame 4. Take out the steel wire brush one by one from the lower layer steel frame 5, and pay attention to keep the steel wire brush intact and reusable.

[0040] Clean and inspect the removed steel frame and steel wire brush, and record the wear and damage for subsequent repair or replacement.

[0041] In use: Check whether the new steel wire brush and steel frame are intact, and ensure that all parts meet the use requirements. Install the lower layer steel frame 5 in the upper layer steel frame 4, ensure that the mesh holes 6 of the two correspond to each other, and fix them using bolts, nuts and anti-skid washers.

[0042] Pass the steel wire brush through the mesh holes 6 of the upper layer steel frame 4 and the lower layer steel frame 5 one by one, and ensure that the straight part 8 of the steel wire brush is correctly fixed on the lower layer steel frame 5. Turn the turnover extrusion plate 2 to properly extrude the steel wire brush, and ensure that the steel wire brush is firmly fixed on the steel frame. Overall check the installed sealing brush to ensure that all parts are correctly and stably installed. Then debug, observe the working state of the sealing brush to ensure that it can meet the use requirements of the shield tunneling machine. After confirming that the sealing brush is installed correctly and debugged normally, restart the shield tunneling machine for normal work.

[0043] The disassembly and use process of the sealing brush of the shield tunneling machine can be ensured to be safe, efficient and accurate. At the same time, regular inspection and replacement of the sealing brush can ensure its long-term stable operation, and improve the working efficiency and service life of the shield tunneling machine.
