Description

Technical Field

[0001] This application relates to the field of tunnel construction technology, and in particular to a manned cabin and a tunnel boring machine. Background Technology

[0002] A tunnel boring machine (TBM) is a tunnel construction device that excavates and lines underground tunnels by cutting through the ground with a cutterhead, protected by a steel shell. TBMs are widely used in tunnel construction due to their advantages such as high construction speed, good safety, and minimal ground settlement. During TBM construction, personnel and equipment need to enter the excavation chamber for equipment maintenance and geological surveys. To maintain the stability of the excavation face and prevent accidents such as water inrush, the excavation chamber is often filled with high-pressure air. Therefore, a personnel cabin is needed to ensure the safe entry of personnel into the excavation chamber. The personnel cabin is a key piece of equipment for pressurized operations during TBM tunneling; it has pressure regulation and safe transition functions. When workers need to enter the excavation chamber under adverse geological conditions, they can safely enter the excavation chamber or the area in front of the cutterhead through the personnel cabin.

[0003] In related technical solutions, the personnel compartment is mostly a rigid structure assembled by welding. The personnel compartment includes a main compartment and a secondary compartment. The main compartment and the shield body of the tunnel boring machine are detachably connected, but the main compartment and the secondary compartment are not separable. This results in the personnel compartment occupying a large equipment installation space, and the secondary compartment has poor adaptability and versatility, leading to low utilization.

[0038] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this application, but not all embodiments.

[0039] Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0040] In related technical solutions, the personnel compartment is mostly a rigid structure assembled by welding. The personnel compartment includes a main compartment and a secondary compartment. The main compartment and the shield body of the tunnel boring machine are detachably connected, but the main compartment and the secondary compartment are not separable. This results in the personnel compartment occupying a large equipment installation space, and the secondary compartment has poor adaptability and versatility, leading to low utilization.

[0041] In view of this, the embodiments of this application aim to provide a manning cabin and a tunnel boring machine. By integrating the main cabin into the shield body of the tunnel boring machine, the auxiliary cabin is detachably connected to the main cabin, thereby reducing the installation space required for the manning cabin. Moreover, after the auxiliary cabin is detached, it can be adapted to the main cabin of other tunnel boring machines. The auxiliary cabin has good adaptability and versatility, which is conducive to improving the utilization rate of the auxiliary cabin.

[0042] The embodiments of this application will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can gain a more detailed understanding of the contents of this application.

It should be noted that, in the description of this embodiment, the first direction X, the second direction Y, and the third direction Z are three different directions that are perpendicular to each other in three-dimensional space.

[0044] Please refer to Figures 1-6 This embodiment provides a manned cabin, including a main cabin 100 and a first auxiliary cabin 200. The main cabin 100 is installed inside the shield body 10 of the tunnel boring machine, and the first auxiliary cabin 200 is detachably connected to the main cabin 100.

[0045] Specifically, the shield body 10 of this embodiment includes a front partition 110 and a rear partition 120 arranged opposite each other along a first direction X, a shield sidewall 130 and a central ring 140 arranged opposite each other along a second direction Y, and a first stiffener 150 and a second stiffener 160 arranged opposite each other along a third direction Z. The two ends of the front partition 110 are respectively connected to the first end of the shield sidewall 130 and the first end of the central ring 140. The second end of the shield sidewall 130 is connected to the rear partition 120. The second end of the central ring 140 and the rear partition 120 are connected by a transition stiffener, which can be configured according to the shape of the shield body. For example, the transition stiffener may include a first transition stiffener 141 and a second transition stiffener 142. The first transition stiffener 141 is perpendicular to the central ring 140 and extends toward the shield sidewall 130, and the second transition stiffener 142 connects the first transition stiffener 141 and the rear partition 120. The two ends of the first stiffening plate 150 are respectively connected to the first end of the front diaphragm 110 and the first end of the rear diaphragm 120, and the two ends of the second stiffening plate 160 are respectively connected to the second end of the front diaphragm 110 and the second end of the rear diaphragm 120. In this embodiment, the front diaphragm 110, the rear diaphragm 120, the shield sidewall 130, the central ring 140, the transition stiffening plate, the first stiffening plate 150 and the second stiffening plate 160 together form the main compartment 100. By integrating the main compartment 100 into the shield body 10 of the tunnel boring machine, the installation space required for the personnel compartment is reduced (that is, only the installation space for the first auxiliary compartment 200 needs to be reserved on the outside of the tunnel boring machine).

[0046] In this embodiment, a first front cabin door 111 is provided on the front bulkhead 110, and a first main cabin door 121 is provided on the rear bulkhead 120. A first connecting welding plate 170 is provided on the side of the first main cabin door 121 away from the front bulkhead 110. The first auxiliary cabin 200 is detachably connected to the first connecting welding plate 170.

[0047] This embodiment uses a detachable connection between the main compartment 100 and the first auxiliary compartment 200 to allow the first auxiliary compartment 200 to be adapted to the main compartment of other tunnel boring machines (i.e., the first auxiliary compartment 200 can be connected to the main compartment of other tunnel boring machines after being detached). The first auxiliary compartment 200 has good adaptability and versatility, which is conducive to improving the utilization rate of the first auxiliary compartment 200.

[0048] In one possible implementation, such as Figure 2As shown, the first auxiliary compartment 200 of this embodiment includes a first front panel 210 and a first rear panel 220 arranged opposite each other along a first direction X, and a first auxiliary compartment side wall 230 and a first connecting wall 240 arranged opposite each other along a third direction Z. The two ends of the first front panel 210 are respectively connected to the first end of the first auxiliary compartment side wall 230 and the first end of the first connecting wall 240, and the two ends of the first rear panel 220 are respectively connected to the second end of the first auxiliary compartment side wall 230 and the second end of the first connecting wall 240. The first front panel 210 is provided with a first main compartment connecting door 211, and the first rear panel 220 is provided with a first auxiliary compartment door 221.

[0049] Furthermore, a first main cabin connecting flange 250 is provided on the side of the first main cabin connecting door 211 facing the first main cabin door 121. The first connecting welding plate 170 has multiple through holes, and the first main cabin connecting flange 250 and the first connecting welding plate 170 are detachably connected by bolts. Through the above configuration, this embodiment achieves a detachable connection between the main cabin 100 and the first auxiliary cabin 200, thereby facilitating improved adaptability and versatility of the first auxiliary cabin 200 and increasing its utilization rate.

[0050] In this embodiment, the first forward hatch 111 is integrated inside the shield body 10 and is an outward-opening door. This eliminates the need for an outward-opening door in the first auxiliary compartment 200, allowing for more flexible dimensional design of the first main compartment connecting flange 250, which better complements the design of the aft bulkhead 120. Furthermore, placing the outward-opening door inside the shield body 10 makes the main compartment 100 a sealed compartment, enabling it to undergo pressure testing independently, thus facilitating the inspection and maintenance of the main compartment 100.

[0051] Please continue to refer to Figure 2 In this embodiment, a first protective plate 260 is also provided on the side of the first rear panel 220 opposite to the first front panel 210. The first protective plate 260 is detachably connected to the first rear panel 220 and shields the first auxiliary hatch 221. Optionally, both the first protective plate 260 and the first rear panel 220 may be provided with flange interfaces, and the two are connected through flanges. When it is necessary to connect the rescue compartment, the first protective plate 260 can be removed from the first rear panel, and then the rescue compartment can be connected to the first rear panel 220 through the flange interface.

[0052] Please continue to refer to Figure 1 and Figure 2In one possible implementation, the personnel compartment of this embodiment further includes a first connecting sleeve 300. The first connecting sleeve 300 includes a first front connecting flange 310 and a first rear connecting flange 320 disposed opposite to each other along a first direction X. The first connecting sleeve 300 is detachably connected to the first connecting welding plate 170 through the first front connecting flange 310, and the first connecting sleeve 300 is detachably connected to the first main compartment connecting flange 250 through the first rear connecting flange 320. When applied to a smaller diameter tunnel boring machine, if the rear bulkhead 120 cannot provide sufficient space to connect the first auxiliary compartment 200, the first connecting sleeve 300 can be used for transfer.

[0053] Specifically, the first connecting sleeve 300 in this embodiment further includes a first sleeve sidewall 330 and a second sleeve sidewall disposed opposite to each other along the second direction Y. The second sleeve sidewall includes a first segment 341, a second segment 342, and a third segment 343. The first segment 341 is connected to the first front connecting flange 310. The two ends of the second segment 342 are perpendicularly connected to the first segment 341 and the third segment 343, respectively. The third segment 343 is connected to the first rear connecting flange 320. In a plane perpendicular to the first direction X, the projection of the first rear connecting flange 320 obscures the projection of the first front connecting flange 310. That is, the cross-sectional area of ​​the first connecting sleeve 300 is smaller on the side closer to the main compartment 100, and larger on the side closer to the first auxiliary compartment 200. This structure ensures that the main compartment 100 can be connected to the first auxiliary compartment 200 via the first connecting sleeve 300.

[0054] Please continue to refer to Figure 2 In one possible implementation, the aft bulkhead 120 of this embodiment is also provided with a second main hatch 122, through which the main cabin 100 can connect to the external environment. When pressurized entry is not required, the main cabin 100 can be directly entered through the second main hatch 122 without having to pass through the first auxiliary cabin 200, thereby improving operational efficiency.

[0055] Please continue to refer to Figure 4 In one possible implementation, the personnel compartment of this embodiment further includes a second auxiliary compartment 400 and a second connecting sleeve 500. A second main door 122 is also provided on the rear bulkhead 120, and the second main door 122 is connected to the second auxiliary compartment 400 via the second connecting sleeve 500. This structure increases the number of people allowed inside the compartment, thereby improving operational efficiency.

[0056] Specifically, the second auxiliary compartment 400 in this embodiment includes a second front panel 410 and a second rear panel 420 arranged opposite each other along a first direction X, and a second auxiliary compartment side wall 430 and a second connecting wall 440 arranged opposite each other along a third direction Z. The two ends of the second front panel 410 are respectively connected to the first ends of the second auxiliary compartment side wall 430 and the first ends of the second connecting wall 440. The two ends of the second rear panel 420 are respectively connected to the second ends of the second auxiliary compartment side wall 430 and the second ends of the second connecting wall 440. The second front panel 410 is provided with a second main compartment connecting door 411, and the second rear panel 420 is provided with a second auxiliary compartment door 421.

[0057] A second main cabin connecting flange 450 is also provided on the side of the second main cabin connecting door 411 facing the second main cabin door 122. A second protective plate 460 is also provided on the side of the second rear panel 420 opposite to the second front panel 410. The second protective plate 460 is detachably connected to the second rear panel 420 and covers the second auxiliary cabin door 421. Similar to the first protective plate 260 mentioned above, when it is necessary to connect the rescue compartment, the second protective plate 460 can also be removed from the second rear panel 420, and then the rescue compartment can be connected to the second rear panel 420 through the flange interface.

[0058] The second connecting sleeve 500 includes a second front connecting flange 510 and a second rear connecting flange 520 disposed opposite to each other along the first direction X. The second connecting sleeve 500 is detachably connected to the second main cabin door 122 through the second front connecting flange 510, and the second connecting sleeve 500 is detachably connected to the second main cabin connecting flange 450 through the second rear connecting flange 520.

[0059] In other possible implementations, such as Figure 5 As shown, the passenger compartment in this embodiment may further include a main compartment 100, a first auxiliary compartment 200, and a second auxiliary compartment 400. The main compartment 100 is directly connected to the first auxiliary compartment 200 and the second auxiliary compartment 400, omitting the structure of the first connecting sleeve 300 and the second connecting sleeve 500. Other structures in this embodiment are the same as described above. Figure 4 The structure of the personnel compartment shown is the same, and will not be described again here. This embodiment can also increase the number of people entering the compartment, thereby improving operational efficiency.

[0060] Please continue to refer to Figures 4-6 In one possible implementation, the first connecting wall 240 of this embodiment is further provided with a first auxiliary compartment connecting door 241, and the second connecting wall 440 is provided with a second auxiliary compartment connecting door 441. The first connecting wall 240 and the second connecting wall 440 are detachably connected, and the first auxiliary compartment connecting door 241 and the second auxiliary compartment connecting door 441 are connected. This structure allows workers to move between the first auxiliary compartment 200 and the second auxiliary compartment 400 through the first auxiliary compartment connecting door 241 and the second auxiliary compartment connecting door 441, thereby improving operational efficiency.

[0061] Please continue to refer to Figure 6 In one possible implementation, the main cabin 100 of this embodiment is further provided with a bulkhead 180, which divides the main cabin 100 into a first sub-main cabin 101 and a second sub-main cabin 102. A first forward cabin door 111 and a first main cabin door 121 are located on the first sub-main cabin 101. A second forward cabin door 112 is also provided on the forward bulkhead 110, and the second forward cabin door 112 and the second main cabin door 122 are located on the second sub-main cabin 102. Other structures of this embodiment are the same as described above. Figure 5 The structure of the personnel compartment shown is the same, and will not be described again here. With the above structure, this embodiment can divide the personnel compartment into two independent working channels (i.e., the first sub-main compartment 101, the first connecting sleeve 300 and the first auxiliary compartment 200 form one working channel, and the second sub-main compartment 102, the second connecting sleeve 500 and the second auxiliary compartment 400 form the other channel). The two working channels can also be connected to the second auxiliary compartment connecting door 441 through the first auxiliary compartment connecting door 241, which effectively improves the efficiency of entering the compartment.

[0062] This embodiment also provides a tunnel boring machine, including the crew cabin as described in the above embodiment.

[0063] Because the tunnel boring machine in this embodiment is equipped with the manned cabin described in the above embodiment, the installation space required for the manned cabin can be reduced. Furthermore, the auxiliary cabin can be adapted to the main cabin of other tunnel boring machines after being disassembled. The auxiliary cabin has good adaptability and versatility, which is conducive to improving the utilization rate of the auxiliary cabin.
