Description

Technical Field

[0001] The present invention relates to the technical field of tunneling machinery, and in particular to a water diversion system and a tunneling machine based on TBM tunneling. Background Art

[0002] TBM, also known as tunnel boring machine, is divided into open tunnel boring machine and shield tunnel boring machine. It is a kind of tunneling, support, slag removal and other construction processes in parallel and continuous operation. It is a factory-based assembly line tunnel construction equipment with mechanical, electrical, hydraulic, optical, gas and other system integration. It has the advantages of fast tunneling speed, environmental protection, high comprehensive benefits, etc. It can realize the construction of deep buried long tunnels in complex geographical features that are difficult to achieve with traditional drilling and blasting methods.

[0003] During the tunnel construction process, TBM (tunnel boring machine) plays a key role. The cutterhead at the front end will continuously rotate, driving the various types of tools installed on it to work together, so as to achieve effective excavation of the rock and soil at the face, and then steadily advance the tunnel construction. As the cutterhead drives the tools to rotate continuously and frequently contact the rock and soil, the tools are in this high-intensity working state for a long time, and will inevitably generate a lot of heat due to the friction between the tools and the rock and soil, causing their own temperature to continue to rise. In order to avoid the adverse effects of high temperature on the performance and service life of the tools, water flushing is usually used to cool the tools. The specific method is to use a pipe to introduce cooling water into the rotating cutterhead, and then let the cooling water flow out of the cutterhead, and then cool the various tools installed on the cutterhead.

[0004] However, in actual construction, since the cutterhead is always in a state of continuous rotation, it is difficult for the cooling water to be evenly distributed to all positions on the cutter, resulting in poor cooling effect, affecting the cooling efficiency and life of the cutter. In addition, there is a lack of effective cooling measures for the drive motor inside the cutterhead.

[0005] Therefore, the prior art needs to be improved. Summary of the invention

[0006] The technical problem to be solved by the present invention is that in the prior art, it is difficult to spray the cooling water of the cutter disc evenly and there is a lack of a cooling mechanism for the drive motor.

[0031] Example 1

[0032] Combination Figures 1 to 4 As shown, a water diversion system based on TBM excavation according to an embodiment of the present invention is shown, and the specific structure is described as follows.

[0033] Reference Figure 1 As shown, the water diversion system based on TBM excavation in this embodiment 1 mainly includes two parts: the excavation part and the water diversion part. The excavation part is mainly used for tunnel excavation operations, and the water diversion part is mainly used for cooling the excavation part and moistening the tunnel soil and rock.

[0034] Further, combined with Figure 1 As shown, the excavation section includes three parts: a drive motor 1, a connecting disc 2 and a cutter disc 3. Three drive motors 1 are installed in this embodiment 1. The three drive motors 1 are evenly spaced, and the main shaft of the drive motor 1 extends vertically downward. The connecting disc 2 is in the shape of a disc. The connecting disc 2 is located between the cutter disc 3 and the drive motor 1. An inner gear ring 202 is installed on the top of the connecting disc 2, and the teeth of the inner gear ring 202 are located on the inner ring. The main shaft of the drive motor 1 is installed with a gear 101, and the three gears 101 are all meshed with the teeth of the inner gear ring 202. The drive motor 1 drives the gear 101 to rotate, and the gear 101 drives the connecting disc 2 to rotate by meshing.

[0035] Furthermore, combined Figure 1 and Figure 2 As shown, the cutter disc 3 is installed below the connecting disc 2, and a mounting groove is provided on the cutter disc 3. A tool 301 for cutting soil and rocks is installed in the mounting groove. Driven by the rotation of the cutter disc 3, the multiple tools 301 play a role in tunnel excavation.

[0036] In some implementations of this embodiment, Figure 2 and Figure 3 As shown, the water diversion part includes a main water diversion pipe 4, a cooling sleeve 5, etc., wherein the main water diversion pipe 4 is a metal round pipe, which is vertically installed in the middle of the three drive motors 1. The cooling sleeve 5 is in the form of a round sleeve, and the three cooling sleeves 5 are respectively installed on the three drive motors 1. A water storage chamber is arranged inside the cooling sleeve 5, and water can flow in the water storage chamber.

[0037] Further, combined with Figure 2 and Figure 3 As shown, each cooling jacket 5 is equipped with a water inlet pipe 501 and a water outlet pipe 502, the water inlet pipe 501 is located on the upper side of the water outlet pipe 502, and the water inlet pipe 501 and the water outlet pipe 502 are both connected to the water storage chamber of the cooling jacket 5. The water inlet end of the water inlet pipe 501 is connected to the main water supply pipe 4. Since the main water supply pipe 4 is connected to the water pump, part of the water in the main water supply pipe 4 enters the cooling jacket 5, taking away the heat on the surface of the drive motor 1, cooling the drive motor 1, ensuring the long-term normal operation of the drive motor 1, and having a good use effect.

[0038] It should be noted that a rectangular groove is provided on the cooling sleeve 5 , and the upper rectangular groove and the lower rectangular groove are not aligned.

[0039] In some implementations of this embodiment, Figure 3 and Figure 4 As shown, a connecting pipe 6 is installed on the end surface of the cutter disc 3 away from the cutter 301, and the connecting pipe 6 is located at the center of the cutter disc 3. The connecting pipe 6 is connected to four water spray pipes 8, and the four water spray pipes 8 are arranged in a radial form and are arranged at equal intervals. Four arc blocks 302 are installed on the cutter disc 3, and the top surface of the arc block 302 is fixedly connected to the bottom surface of the connecting disc 2.

[0040] Combination Figure 4 As shown, an L-shaped water hole 303 is provided inside the arc block 302, and the water hole 303 extends to the inside of the cutter head 3 until the installation groove of the cutter 301 is installed. The water spray pipe 8 is connected to the arc block 302, and the water outlet of the water spray pipe 8 is connected to the water hole 303, so that the water flow transported in the water spray pipe 8 flows out from the installation groove, cools the cutter 301, and wets the soil and rocks, which is convenient for crushing and conducive to excavation operations. Multiple water holes 303 allow water to be sprayed more evenly.

[0041] It should be noted that, combined with Figure 3As shown, a through hole 201 is opened in the center of the connection disk 2, and the connection pipe 6 passes through the through hole 201.

[0042] Further, combined with Figure 3 and Figure 4 As shown, the connecting pipe 6 and the main water supply pipe 4 are rotatably connected, and the annular pipe sleeve 7 includes a first pipe sleeve 701 and a second pipe sleeve 702. The first pipe sleeve 701 covers the outside of the connecting pipe 6, and the second pipe sleeve 702 is sleeved on the bottom end of the main water supply pipe 4. The first pipe sleeve 701 and the second pipe sleeve 702 are rotatably connected through a connecting rotary joint. The outlet end of the water outlet pipe 502 is connected to the second pipe sleeve 702.

[0043] By sleeve-mounting the cooling sleeve 5 on the outer surface of the driving motor 1, and then connecting the water inlet pipe 501 connected to the outer surface of the cooling sleeve 5 to the inside of the main water pipe 4, the cooling water inside the main water pipe 4 can be introduced into the inside of the cooling sleeve 5, and the cooling water flows inside the cooling sleeve 5, which can accelerate the heat dissipation efficiency of the driving motor 1 and cool the driving motor 1 that continuously drives the connecting disk 2 to rotate. In addition, the water outlet pipe 502 is connected to the bottom of the outer surface of the cooling sleeve 5, and the second pipe sleeve 702 is sleeved on the outer surface of the main water pipe 4. The bottom of the second pipe sleeve 702 is rotatably connected to the first pipe sleeve 701, and the other end of the water outlet pipe 502 is connected to the inside of the second pipe sleeve 702, so that the water flow inside the cooling sleeve 5 can be injected into the inside of the second pipe sleeve 702 and the first pipe sleeve 701, so that the water source flows out from the water outlet hole opened on one side of the second pipe sleeve 702 close to the installation groove, so that the water flow can flow out from the installation groove 2 opened in the middle of the cutter head 3, so as to achieve the effect of cooling the driving motor 1.

[0044] It should be noted that, combined with Figure 4 As shown, considering that the second pipe sleeve 702 being sleeved onto the outer surface of the connecting pipe 6 may cause obstruction to the water spray pipe 8, an insertion port is provided on the outer surface of the first pipe sleeve 701, and the water spray pipe 8 passes through the insertion port of the first pipe sleeve 701.

[0045] Example 2

[0046] This embodiment 2 provides a tunnel boring machine, which adopts the water diversion system based on TBM tunneling in embodiment 1.

[0047] In summary, the working principles of the water diversion system and the tunnel boring machine based on TBM excavation of the present invention are as follows:

[0048] When using TBM for excavation, the three driving motors 1 rotate synchronously, driving the connecting disc 2 and the cutter disc 3 to rotate and break the rock and soil. When the connecting disc 2 and the cutter disc 3 rotate, the connecting pipe 6 will be driven to rotate together. The main water pipe 4 and the connecting pipe 6 are connected by the first pipe sleeve 701, the rotating joint, and the second pipe sleeve 702 of the annular pipe sleeve 7 to achieve rotational connection, so that the main water pipe 4 remains stationary. The main water pipe 4 conveys water to the connecting pipe 6, so that the cooling water can convey water to the water holes 303 in the cutter disc 3 and the arc block 302 through the water spray pipe 8. The water flows out from the installation groove to cool the tool 301 in the installation groove, thereby achieving the effect of cooling the tool 301 installed on the cutter disc 3.

[0049] The main water supply pipe 4 transports cooling water to the interior of the cooling sleeve 5 which is sleeved on the outer surface of the driving motor 1 through the water inlet pipe 501, so that the cooling water circulates in the cooling sleeve 5, which can quickly take away the heat of the driving motor 1 and cool the driving motor 1. The water in the cooling sleeve 5 can flow through the water outlet pipe 603, the second pipe sleeve 702 and the first pipe sleeve 701, and flow out from the water outlet to discharge the used water in the cooling sleeve 5, and the discharged water can flow out from the installation groove, thereby achieving the effect of cooling the driving motor 1.
