[0020] Example 1: In existing technologies, when a newly constructed subway line passes through an existing subway line, the tunnel boring machine (TBM) needs to pass through the diaphragm wall of the existing subway station. However, because the diaphragm wall contains thick, mesh-like reinforcing bars, the TBM cannot pass directly through it. It is necessary to destroy the reinforcing bars at a designated location (approximately ten meters underground) before the TBM can pass through. Current construction methods cannot precisely destroy the diaphragm wall at the designated location, often requiring large-scale destruction of the diaphragm wall, which is very time-consuming and labor-intensive.

The cross-sectional dimensions of the cutting device 10 are determined by the connecting housing 400. Therefore, when the cutting device 10 moves within the deep well 20, the connecting housing 400 can simultaneously move along the first direction X within the deep well 20, and a certain gap is always maintained between the connecting housing 400 and the sidewall of the deep well 20. The connecting housing 400 has a certain length in the first direction X, and has a receiving cavity 410 inside to accommodate other components within the cutting device 10. A first surface 440 is provided on one side of the connecting housing 400 along the first direction X. A first intermediate member 420 is also provided on the connecting housing 400, protruding from the first surface 440. The first intermediate member 420 is provided for further connecting other components in the cutting device 10. The specific structure of the first intermediate member 420 will be further described in conjunction with other components in subsequent embodiments.

[0023] Please refer to the attached document. Figure 1As shown, the cutting device 10 of this application includes a cutting element 100, which is a specific working component of the cutting device 10. The cutting element 100 rotates at high speed around the first rotation axis 110 under the drive of other components. The cutting element 100 in the rotating state contacts the cutting area 21 under the drive of other components, and can further cut the items in the cutting area 21.

[0024] In one embodiment, the cutting element 100 is a cutting blade. Further, one or two cutting blades are provided.

[0025] Please refer to the attached document. Figure 1 As shown, the cutting device 10 of this application includes a first driving member 200 and a first transmission member 300. The first driving member 200 is connected to the cutting member 100 through the first transmission member 300 to drive the cutting member 100 to rotate at high speed. The first driving member 200 can be disposed inside or outside the connecting housing 400. Further, the first driving member 200 is disposed outside the connecting housing 400 and extends along the first direction X to reduce the lateral area of ​​the cutting device 10. The first driving member 200 is connected to the connecting housing 400, and the driving end of the first driving member 200 extends into the receiving cavity 410 and is connected to the first transmission member 300 located in the receiving cavity 410.

The first transmission structure 310 is connected to the driving end of the first driving component 200, and the first driving component 200 drives the first transmission structure 310 to move. The third transmission structure 330 is connected to the cutting blade. The second transmission structure 320 is located between the first transmission structure 310 and the third transmission structure 330 to transfer the kinetic energy of the first driving component 200 to the cutting component 100 and drive the cutting component 100 to rotate at high speed. The second transmission structure 320 is rotatably connected to the first intermediate component 420 through the first connecting member 500 to support the first transmission component 300 on the connecting housing 400.

[0027] In one embodiment, the first transmission member 300 is a gear transmission structure or a pulley transmission structure. Further, the first transmission member 300 is a gear transmission structure, and the first transmission structure 310, the second transmission structure 320, and the third transmission structure 330 are all transmission gears.

[0028] Please refer to the attached document. Figure 1As shown, the cutting device 10 of this application includes a second driving member 800, which is connected to the cutting member 100. The second driving member 800 drives the cutting member 100 to move by rotation or translation, thereby realizing the movement control of the cutting member 100. This allows the user to control the cutting device 10 even outside the deep well 20, enhancing its safety performance. The rotation and movement of the cutting member 100 have a certain sequence. When cutting an item in the cutting area 21, the cutting member 100 needs to be rotated first, and then moved closer to the cutting area 21, so that the cutting member 100 contacts the cutting area 21. When stopping the cutting of an item in the cutting area 21, the cutting member 100 needs to be moved away from the cutting area 21 first, and then the rotation of the cutting member 100 needs to be stopped, so that the cutting member 100 is no longer in contact with the cutting area 21.

[0029] The second driving component 800 is connected to the cutting component 100, and during the process of driving the cutting component 100 to move, the cutting device 10 is in a first state and a second state. In the first state, the cutting component 100 is separated from the cutting area 21.

As mentioned above, the connection between the cutting piece 100 and the first transmission piece 300 is to realize the rotation of the cutting piece 100, while the connection between the cutting piece 100 and the first intermediate piece 420 is to realize the movement of the cutting piece 100.

[0031] The second connecting member 600 includes a first connecting structure 610, which is connected to the third transmission structure 330. Under the rotation of the third transmission structure 330, the first connecting structure 610 rotates synchronously, and the center of the first connecting structure 610 coincides with the second rotation axis 423.

The first connecting structure 610 and the second connecting structure 620 are connected, and the second connecting structure 620 is connected to the cutting piece 100.

Further, the first connecting structure 610 is a ring structure, and the second connecting structure 620 is a long strip structure. The second connecting structure 620 is arranged on one side of the first connecting structure 610 along the radial direction, and both ends of the second connecting structure 620 in the length direction are connected to the first connecting structure 610. The second connecting structure 620 forms a rotatable connection with the first intermediate structure. More specifically, under the drive of the second driving member 800, the second connecting member 600 is rotatably connected to the first intermediate member 420 through the second connecting structure 620, thereby realizing the movement of the cutting piece 100.

[0033] Furthermore, the number of cutting components 100 is equal to the number of third transmission structures 330. In one embodiment, both the number of cutting components 100 and the number of third transmission components are two.

[0034] Please refer to the attached document. Figure 1 As shown, the first intermediate component 420 of this application is a sleeve structure to facilitate the rotational connection between the second transmission structure 320 and the second connecting structure 620. In this application, the rotational connection can be achieved through the outer surface or the inner surface of the first intermediate component 420. That is, the second transmission structure 320 can be rotated through the outer surface or the inner surface of the first intermediate component 420, and the second connecting structure 620 can be rotated through the outer surface or the inner surface of the first intermediate component 420.

[0035] Furthermore, the first intermediate component 420 has a through-hole 430 along a third direction Z, which communicates with the receiving cavity 410.

The second transmission structure 320 is rotatably connected to the first inner surface 422 via the first connector 500, and the second connection structure 620 is rotatably connected to the first outer surface 421.

[0036] In one embodiment, the first connector 500 is a bearing or a bushing.

[0037] Please refer to the attached document. Figure 1As shown, the cutting device 10 of this application includes a limiting member 700, which is provided to prevent the second connecting member 600 from moving further along the third direction Z. The limiting member 700 is disposed on the side of the first intermediate member 420 along the third direction Z and away from the first surface 440. The limiting member 700 is detachably connected to the first intermediate member 420, and the limiting member 700 protrudes from the first outer surface 421 to limit the second connecting structure 620 between the limiting member 700 and the first outer surface 421.

[0038] In one embodiment, the limiting member 700 has a disc-shaped structure.

[0039] Please refer to the attached document. Figure 1 As shown, the second connector 600 of this application also includes a third connector 630. The first connector 610 is located inside the receiving cavity 410 for easy connection with the second transmission structure 320, and the second connector 620 is located outside the receiving cavity 410 for easy connection with the cutting component 100. The first connector 610 and the second connector 620 are spaced apart along the third direction Z, and the third connector 630 is located between the first connector 610 and the second connector 620. The first connector 610 is connected to the second connector 620 through the third connector 630, which is an elongated structure. A limiting groove 450 is formed on the first surface 440. The limiting groove 450 penetrates the side wall with the first surface 440 along the third direction Z. The limiting groove 450 is connected to the receiving cavity 410. The third connecting structure 630 is located in the limiting groove 450. Under the rotation of the second connecting member 600, the third connecting structure 630 moves synchronously in the limiting groove 450 to limit the rotation angle of the cutting member 100.

[0040] In one embodiment, the limiting groove 450 is an arc-shaped structure, and the limiting groove 450 includes a first end and a second end along its circumferential direction. When the third connecting structure 630 abuts against the first end of the limiting groove 450, the cutting device 10 is in a first state. When the third connecting structure 630 abuts against the second end of the limiting groove 450, the cutting device 10 is in a second state.

[0041] Appendix Figure 2 This is a schematic diagram of the structure of the cutting equipment 10 after removing the cutting part 100. Please refer to the attached diagram. Figure 2As shown, the second driving component 800 of this application includes driving ropes. A first connecting ring and a second connecting ring are respectively provided on both sides of the second connecting structure 620. The first ends of the two driving ropes are connected to the first connecting ring and the second connecting ring, respectively. A guide post is provided on the connecting housing 400. After passing through the guide post, the two connecting ropes extend upward along the first direction X and out of the deep well 20. The second driving component 800 also includes a driving body located outside the deep well 20. The second end of the connecting rope is connected to the driving body. The driving body is used to wind or unwind the connecting ropes to achieve rotation of the second connecting component 600 around the first intermediate component 420. At this time, the third transmission structure 330 rotates synchronously around the second transmission structure 320. The driving body can be an automatic structure or a manual structure. The second driving component 800 allows for operation of the cutting device 10 outside the deep well 20, thereby enhancing operational efficiency while minimizing the size of the cutting device 10 and the drilling size of the deep well 20, enabling rapid cutting of the diaphragm wall at a specified location.
