DETAILED DESCRIPTION

[0051] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0052] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of this application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present application described herein can, for example, be implemented in an order other than those illustrated or described herein.

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

[0054] In the description of the embodiments of the present application, it should be understood that the terms "inside", "outside", "top", "bottom", "front", "back", etc. indicating the orientation or position relationship (if any) are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0055] The existing conventional hard rock tunnel boring machine includes a chassis, a cutterhead, a main drive, and a main beam, wherein the main beam is installed on the chassis, the cutterhead is installed at the front end of the main beam, and the main drive is installed at the front end of the main beam and directly connected to the cutterhead. The main drive provides power to the cutterhead to drive the cutterhead to rotate.

[0056] In the above scheme, since the main drive is located at the front end of the main beam, the overall center of gravity of the tunnel boring machine tilts forward, which makes the counterweight distribution of the tunnel boring machine unbalanced, affecting the stability of the tunnel boring machine during the tunneling process.

[0057] Therefore, the present application proposes a roadheader with a rear main drive, which changes the center of gravity of the roadheader by adjusting the position of the main drive, so as to make the weight distribution of the roadheader more reasonable and improve the stability of the roadheader during the excavation process. The application will be described in detail below with reference to the accompanying drawings.

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

[0060] like Figure 1 As shown, a tunnel boring machine provided in the present application includes a support 100, a main beam 200, one end of which is connected to the support 100 and the other end extends out of the support 100, a main drive 300, which is arranged at one end of the main beam 200 close to the support 100, a main bearing 400, which is arranged at one end of the main beam 200 away from the support 100, and a cutter head 500, which is arranged on the main bearing 400.

[0061] The two ends of the transmission shaft 600 are respectively connected to the main drive 300 and the main bearing 400 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 the present application, since the main drive 300 is located behind the main beam 200, power transmission is achieved through the transmission shaft 600. This not only ensures the layout space of the support shoe propulsion system, but also optimizes the weight ratio of the whole machine, ensuring that the center of gravity is located at the center of the chassis, which is beneficial to the stability of the tunnel boring machine during the excavation process.

[0063] The bracket 100 is used to connect and support various components of the tunnel boring machine. The bottom of the main drive 300 is connected to the top of the bracket 100, one end of the main beam 200 is fixedly connected to the bracket 100, the output end of the main drive 300 is connected to one end of the transmission shaft 600, the main beam 200 is located below the transmission shaft 600, the front end of the transmission shaft 600 is meshed and connected to the main bearing 400, the axis of the main bearing 400 is fixedly connected to the main beam 200, the outer ring of the main bearing 400 is driven to rotate through the transmission shaft 600, and the cutter head 500 connected to the main bearing 400 is driven to rotate through the outer ring to crush the rock mass in front.

[0064] In the embodiment provided in the present application, the tunnel boring machine also includes a crawler walking module 900, which includes a crawler driving component 910 arranged at the bottom of the bracket 100 and two crawler wheels 920 arranged on both sides of the bracket 100. The crawler driving component 910 is used to drive the crawler wheels 920 to rotate to drive the tunnel boring machine to move.

[0065] The crawler driving member 910 includes an electric motor or an engine, and the crawler driving member 910 and the crawler wheel 920 are both located in the middle of the tunnel boring machine.

[0066] Combination Figures 1 to 3 As shown, in the embodiment provided in the present application, the tunnel boring machine further includes a gripper shoe propulsion module 700 , and the gripper shoe propulsion module 700 includes a saddle frame 710 and two groups of gripper shoe propulsion assemblies 720 arranged on both sides of the saddle frame 710 .

[0067] The saddle frame 710 is slidingly connected to the main beam 200, and the support shoe propulsion assembly 720 includes a support shoe 721, a tightening cylinder 722 and a propulsion cylinder 723. The tightening cylinder 722 is arranged on the saddle frame 710, and the support shoe 721 is arranged on the tightening cylinder 722. The support shoe 721 moves in a direction perpendicular to the saddle frame 710 under the drive of the tightening cylinder 722. The propulsion cylinder 723 is arranged 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] Among them, the support shoe propulsion module 700 is arranged in the middle part of the tunnel boring machine, the saddle frame 710 is slidably mounted on the outer side of the main beam 200, the saddle frame 710 can slide along the main beam 200, and two sets of support shoe propulsion assemblies 720 are respectively arranged on both sides of the main beam 200, and the support shoe 721 assemblies on both sides provide driving force for the tunnel boring machine.

[0069] Combination Figure 1 and Figure 5 As shown, in the embodiment provided in the present application, the tunnel boring machine also includes a slag collecting module 1000 and a transport module 1100. The slag collecting module 1000 is arranged behind the cutter disc 500, and the transport module 1100 is arranged on the bracket 100. The slag collecting module 1000 is connected to the transport module 1100.

[0070] The debris collection module 1000 includes a debris shovel 1010 and at least one rotating wheel 1020 . The rotating wheel 1020 is disposed inside the debris shovel 1010 . The debris shovel 1010 is used to scoop up the debris and transfer the debris to the transportation module 1100 through the rotating wheel 1020 .

[0071] The lower surface of the slag shovel 1010 is slightly higher than the lower surface of the track wheel 920. When the slag shovel 1010 shovels away the slag, the track wheel will compact the slag on both sides. In order to make the ground inside the tunnel more flat, the slag higher than the two sides is compacted by a roller. By backfilling the tunnel with part of the slag, the tunnel ground is made more flat.

[0072] In the embodiment provided in the present application, the rotating wheel 1020 includes at least one fan blade 1021, and a fixed block 1022 is provided on the fan blade 1021, and the fixed block 1022 is used to drive the debris to move.

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

[0074] In the embodiment provided in the present application, the transport module 1100 includes a conveyor belt, and the shovel 1010 is arranged at the input end of the conveyor belt.

[0075] The conveyor belt extends from the cutter head 500 to the rear of the tunnel boring machine and is used to transfer the collected debris to the rear dump truck.

[0076] like Figure 6 As shown, in the embodiment provided in the present application, the tunnel boring machine further includes two anchor drilling machine modules 800 , and the anchor drilling machine modules 800 are arranged on the bracket 100 .

[0077] Two anchor drilling rig modules 800 are respectively arranged on both sides of the bracket 100. The anchor drilling rig module 800 includes an anchor drilling rig 810 and a slide rail 820. The slide rail 820 is arranged on the bracket 100. The anchor drilling rig 810 is slidably connected to the slide rail 820. The sliding direction of the anchor drilling rig 810 is parallel to the center line direction of the tunnel, so that it can move forward and backward along the center line direction of the tunnel. It is used to flexibly adjust the position of the anchor after the tunnel boring machine is fixed, and provide anchor support for the tunnel.

[0078] like Figure 4 As shown, in the embodiment provided in the present application, the tunnel boring machine also includes at least three groups of shield modules 1300, each shield module 1300 is respectively arranged on both sides and the top of the main drive 300, and the shield module 1300 includes a main shield 1310, a limit block 1320, a limit groove 1330 and a lifting cylinder 1340.

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

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

[0081] Among them, the top shield module 1300 stretches out to hold the top tunnel wall tightly, thereby stabilizing the tunnel boring machine. After the shield modules 1300 on both sides hold the tunnel walls on both sides tightly, the direction of the cutter head 500 can be slightly adjusted by controlling the amount of extension and contraction.

[0082] The main shield 1310 in the shield module 1300 moves driven by the lifting cylinder 1340 .

[0083] In the embodiment provided in the present application, the shield module 1300 further includes a secondary shield 1350 , which is disposed in the primary shield 1310 and slidably connected to the primary shield 1310 , and the secondary shield 1350 is used to shield a gap between two adjacent primary shields 1310 .

[0084] Since the main shield 1310 needs to be stretched during the excavation process, the gap between two adjacent main shields 1310 will increase. In order to prevent gravel from entering the tunnel boring machine through the gap, a secondary shield 1350 needs to be set on the main shield 1310 to fill the gap and protect the internal parts of the tunnel boring machine.

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

[0086] Refer to Figure 1 In the embodiment provided in the present application, the tunnel boring machine further includes a protective cover 1200 , which is disposed around the outside of the main bearing 400 .

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

[0088] The application process includes:

[0089] After the tunnel boring machine is started, the power generated by the main drive 300 is transmitted to the main bearing 400 through the transmission shaft 600, and the rotation of the main bearing 400 drives the cutter head 500 to rotate.

[0090] The gripper shoe 721 holds the cave wall tightly under the action of the tightening cylinder 722, providing a propulsion reaction force for the cutter head 500 to dig forward, and the propulsion cylinder 723 extends forward to push the cutter head 500 forward to dig forward, while the crawler walking module 900 also moves forward, providing a propulsion force for the cutter head 500 to dig forward;

[0091] The slag generated by the excavation of the cutter disc 500 is scooped up by the shovel on the cutter disc 500 and falls to the bottom area behind the cutter disc 500. The slag collecting module 1000 collects the bottom slag to the conveyor belt through two rotating wheels 1020 arranged inside; the conveyor belt transports the slag to the slag truck (or continuous belt conveyor) behind the equipment, and the slag truck (continuous belt conveyor) transports the slag out of the hole;

[0092] After the propulsion cylinder 723 completes a propulsion stroke, the crawler walking module 900 stops moving forward, the support shoe 721 is released, and the propulsion cylinder 723 retracts, driving the support shoe 721 and the saddle frame 710 to slide forward on the main beam 200, completing the step-changing action;

[0093] Repeat the above steps to complete the entire tunnel excavation process;

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

[0095] To sum up, in this application, since the main drive is located behind the main beam and power transmission is achieved through the drive shaft, this not only ensures the layout space of the support shoe propulsion system, but also optimizes the weight ratio of the whole machine, ensuring that the center of gravity is located at the center of the chassis, which is beneficial to the stability of the whole machine.
