These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to specific embodiments. Detailed Implementation

[0051] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0052] The terms “first,” “second,” “third,” “fourth,” etc. (if present) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a particular order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented, for example, in a sequence other than those illustrated or described herein.

[0053] In this application, the terms "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in this application should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0054] In the description of the embodiments of this application, it should be understood that the terms "inner", "outer", "upper", "bottom", "front", "rear", etc., indicate the orientation or positional relationship (if any) based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0055] Existing conventional hard rock tunnel boring machines include a chassis, cutterhead, main drive, and main beam. The main beam is mounted on the chassis, the cutterhead is mounted at the front end of the main beam, and the main drive is mounted at the front end of the main beam and directly connected to the cutterhead. The main drive provides power to the cutterhead, causing the cutterhead to rotate.

[0056] In the above scheme, the main drive is located at the front end of the main beam, which causes the overall center of gravity of the tunneling machine to tilt forward, resulting in an unbalanced weight distribution of the tunneling machine and affecting the stability of the tunneling machine during the tunneling process.

[0057] Therefore, this application proposes a tunneling machine with a rear-mounted main drive. By adjusting the position of the main drive, the center of gravity of the tunneling machine is changed, thereby making the weight distribution of the tunneling machine more reasonable and improving the stability of the tunneling machine during the tunneling process. The application will be described in detail below with reference to the accompanying drawings.

[0058] in, Figure 1 This is a schematic diagram of the tunneling machine proposed in this application; Figure 2 for Figure 1 Cross-sectional view of the support shoe propulsion module of the tunnel boring machine; Figure 3 for Figure 1 Top view of the support shoe propulsion module of the tunnel boring machine;

[0059] Figure 4 for Figure 1 Cross-sectional view of the shield module of a tunnel boring machine; Figure 5 This is a schematic diagram of the structure of the excavator soil collection module in the tunneling machine proposed in this application; Figure 6 for Figure 1 Enlarged view of point A in the middle.

[0060] like Figure 1 As shown, the tunneling machine provided in this application includes a support 100, a main beam 200 with one end connected to the support 100 and the other end extending out of the support 100, a main drive 300 disposed at the end of the main beam 200 near the support 100, a main bearing 400 disposed at the end of the main beam 200 away from the support 100, and a cutterhead 500 disposed on the main bearing 400.

[0061] The drive shaft 600 is connected to the main drive 300 and the main bearing 400 at both ends, so as to transmit the force generated by the main drive 300 to the main bearing 400, so that the main bearing 400 drives the cutter head 500 to rotate.

[0062] In this application, since the main drive 300 is located behind the main beam 200 and power is transmitted through the drive shaft 600, this not only ensures the layout space of the support shoe propulsion system, but also optimizes the weight distribution of the whole machine, ensuring that the center of gravity is located in the center of the chassis, which is beneficial to the stability of the tunneling machine during the tunneling process.

[0063] The support frame 100 is used to connect and support the various components of the tunneling machine. The bottom of the main drive 300 is connected to the top of the support frame 100, one end of the main beam 200 is fixedly connected to the support frame 100, the output end of the main drive 300 is connected to one end of the drive shaft 600, the main beam 200 is located below the drive shaft 600, the front end of the drive shaft 600 is meshed with the main bearing 400, the shaft of the main bearing 400 is fixedly connected to the main beam 200, the drive shaft 600 drives the outer ring of the main bearing 400 to rotate, and the outer ring drives the cutterhead 500 connected to the main bearing 400 to rotate, so as to break the rock mass in front.

[0064] In the embodiments provided in this application, the tunneling machine further includes a tracked walking module 900. The tracked walking module 900 includes a track drive component 910 disposed at the bottom of the support 100 and two track wheels 920 disposed on both sides of the support 100. The track drive component 910 is used to drive the track wheels 920 to rotate, so as to move the tunneling machine.

[0065] The track drive component 910 includes an electric motor or engine, and both the track drive component 910 and the track wheel 920 are located in the middle of the tunneling machine.

[0066] Combination Figures 1 to 3 As shown in the embodiments provided in this application, the tunneling machine further includes a support shoe propulsion module 700, which includes a saddle 710 and two sets of support shoe propulsion assemblies 720 disposed on both sides of the saddle 710.

[0067] The saddle frame 710 is slidably connected to the main beam 200. The support shoe propulsion assembly 720 includes a support shoe 721, a tensioning cylinder 722, and a propulsion cylinder 723. The tensioning cylinder 722 is mounted on the saddle frame 710, and the support shoe 721 is mounted on the tensioning cylinder 722. The support shoe 721 moves in a direction perpendicular to the saddle frame 710 under the drive of the tensioning cylinder 722. The propulsion cylinder 723 is mounted on the main beam 200, and the output end of the propulsion cylinder 723 is connected to the saddle frame 710. The propulsion cylinder 723 drives the saddle frame 710 to move on the main beam 200.

[0068] The support shoe propulsion module 700 is located in the middle of the tunneling machine, the saddle 710 is slidably sleeved on the outside of the main beam 200, the saddle 710 can slide along the main beam 200, and two sets of support shoe propulsion components 720 are respectively located on both sides of the main beam 200. The support shoe 721 components on both sides provide propulsion force for the tunneling machine to tunnel.

[0069] Combination Figure 1 and Figure 5 As shown in the embodiments provided in this application, the tunneling machine also includes a muck collection module 1000 and a transport module 1100. The muck collection module 1000 is located behind the cutterhead 500, and the transport module 1100 is located on the support 100. The muck collection module 1000 and the transport module 1100 are connected.

[0070] The construction waste collection module 1000 includes a construction waste shovel 1010 and at least one rotating wheel 1020. The rotating wheel 1020 is disposed inside the construction waste shovel 1010. The construction waste shovel 1010 is used to scoop up construction waste and transport it to the transportation module 1100 via the rotating wheel 1020.

[0071] The lower surface of the shovel 1010 is slightly higher than the lower surface of the track wheel 920. While the shovel 1010 removes the excavated soil, the track wheel compacts the soil on both sides. To make the tunnel floor smoother, a road roller further compacts the soil that is higher than the sides. By backfilling the tunnel with the aforementioned excavated soil, the tunnel floor becomes smoother.

[0072] In the embodiments provided in this application, the rotating wheel 1020 includes at least one fan blade 1021, and a fixing block 1022 is provided on the fan blade 1021. The fixing block 1022 is used to drive the slag to move.

[0073] Among them, the fixing block 1022 is an inclined block so that the fixing block 1022 can better collect the slag.

[0074] In the embodiments provided in this application, the transportation module 1100 includes a conveyor belt, and the slag shovel 1010 is disposed at the input end of the conveyor belt.

[0075] The conveyor belt extends from the cutterhead 500 section all the way to the rear of the tunneling machine to transfer the collected excavated soil to the dump trucks at the rear.

[0076] like Figure 6 As shown in the embodiments provided in this application, the tunneling machine also includes two anchor drilling modules 800, which are mounted on the support 100.

[0077] Two anchor drilling modules 800 are respectively installed on both sides of the support 100. Each anchor drilling module 800 includes an anchor drilling machine 810 and a slide rail 820. The slide rail 820 is installed on the support 100. The anchor drilling machine 810 is slidably connected to the slide rail 820. The sliding direction of the anchor drilling machine 810 is parallel to the centerline of the tunnel, allowing it to move back and forth along the centerline of the tunnel. This is used to flexibly adjust the position of the anchor after the tunneling machine is fixed and to provide anchor support for the tunnel.

[0078] like Figure 4 As shown in the embodiments provided in this application, the tunneling machine also includes at least three sets of shield modules 1300. Each shield module 1300 is respectively disposed on both sides and the top of the main drive 300. The shield module 1300 includes a main shield 1310, a limiting block 1320, a limiting groove 1330 and a lifting cylinder 1340.

[0079] The limiting groove 1330 is set on the main drive 300, and the limiting block 1320 is set on the main shield 1310. The limiting block 1320 is inserted into the limiting groove 1330 and can slide within the limiting groove 1330.

[0080] The two ends of the lifting cylinder 1340 are connected to the main shield 1310 and the main drive 300 respectively, so as to drive the main shield 1310 to extend or retract relative to the main drive 300.

[0081] The top shield module 1300 extends and tightens the top tunnel wall, stabilizing the tunneling machine. The side shield modules 1300 tighten the tunnel walls on both sides, and the direction of the cutterhead 500 can be slightly adjusted by controlling their extension and retraction.

[0082] The main shield 1310 in the shield module 1300 moves under the action of the lifting cylinder 1340.

[0083] In the embodiments provided in this application, the shield module 1300 further includes a secondary shield 1350, which is disposed inside the main shield 1310 and slidably connected to the main shield 1310. The secondary shield 1350 is used to cover the gap between two adjacent main shields 1310.

[0084] As the main shield 1310 needs to extend during the tunneling process, the gap between two adjacent main shields 1310 will increase. In order to prevent debris from entering the tunneling machine through the gap, a secondary shield 1350 needs to be installed on the main shield 1310 to fill the gap and protect the internal components of the tunneling machine.

[0085] The inner wall of the main shield 1310 and the outer wall of the secondary shield 1350 are slidably connected by a slide rail, allowing the secondary shield 1350 to move relative to the main shield 1310, so as to extend or hide the secondary shield 1350 from the main shield 1310, thereby blocking the gap between adjacent main shields 1310. The extension length of the secondary shield 1350 can be adjusted according to the site conditions.

[0086] Refer to Figure 1 In the embodiments provided in this application, the tunneling machine also includes a protective cover 1200, which is disposed around the outside of the main bearing 400.

[0087] The protective cover 1200 is located behind the cutter head 500 and outside the main bearing 400 to protect the main bearing 400 inside.

[0088] The steps involved in this application include:

[0089] After the tunneling machine is started, the power generated by the main drive 300 is transmitted to the main bearing 400 through the drive shaft 600. The rotation of the main bearing 400 drives the cutterhead 500 to rotate.

[0090] Under the action of the tensioning cylinder 722, the support shoe 721 tightens the tunnel wall, providing a propulsive reaction force for the cutterhead 500 to excavate. The propulsion cylinder 723 extends forward to push the cutterhead 500 forward to excavate. At the same time, the track walking module 900 also moves forward, providing propulsive force for the cutterhead 500 to excavate forward.

[0091] The excavated soil produced by the cutterhead 500 is scooped up by the shovel on the cutterhead 500 and falls into the bottom area behind the cutterhead 500. The excavated soil collection module 1000 collects the bottom excavated soil to the conveyor belt through two rotating wheels 1020 arranged inside. The conveyor belt transports the excavated soil to the excavated soil truck (or continuous belt conveyor) at the rear of the equipment, and the excavated soil is transferred out of the tunnel by the excavated soil truck (continuous belt conveyor).

[0092] After the propulsion cylinder 723 completes one propulsion stroke, the track travel module 900 stops moving forward, the support shoe 721 is released, the propulsion cylinder 723 retracts, and drives the support shoe 721 and saddle 710 to slide forward on the main beam 200 to complete the step change action;

[0093] The entire tunnel excavation process can be completed by repeating the above steps;

[0094] After completing the excavation of a tunnel, the tracked walking module 900 can drive the entire machine to move to another site, realizing the requirements of rapid relocation and face-changing in multi-channel complex space tunnels.

[0095] In summary, in this application, since the main drive is located behind the main beam and power is transmitted through the drive shaft, this not only ensures the layout space of the support shoe propulsion system, but also optimizes the overall weight distribution and ensures that the center of gravity is located in the center of the chassis, which is beneficial to the stability of the whole machine.
