Description

Technical Field

[0001] The present invention relates to the technical field of tunnel boring machines, and in particular to a slope adjustment device for a tunnel boring machine, a tunnel boring machine and a tunneling system. Background Art

[0002] During tunnel excavation, the cutting and rotating parts of the tunnel boring machine are generally integrated with a bridge-type transfer machine. The slide of the transfer machine cooperates with the sliding base at the bottom of the tunnel boring machine. The slide is usually laid on the tunnel floor, realizing tunneling operations along a fixed track. However, in the actual construction process, the tunnel floor presents an uneven shape due to the geological structure. In particular, during the operation of the EBZ135 type tunnel boring machine, the tunnel boring machine has difficulty matching the slope changes of the tunnel floor, resulting in difficulty in strictly following the centerline during excavation. Problems such as tunnel forming deviation, over-excavation or under-excavation are prone to occur. This not only increases the cost of tunnel repair in the later stage, but also leads to poor adaptability of the equipment under complex geological conditions and low construction efficiency, making it difficult to meet the efficient and precise construction requirements of modern tunnel projects.

[0025] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0026] like Figures 1 to 5As shown, an embodiment of the present invention provides a slope adjustment device for a tunnel boring machine, comprising a slideway 10 and a plurality of adjustment assemblies 20. The slideway 10 extends along the tunneling direction of the tunnel. The plurality of adjustment assemblies 20 are arranged on the slideway 10 at intervals along the tunneling direction. The adjustment assemblies 20 include a support cylinder 21, a guide seat 22, a connecting rod 23, and a sliding seat 24. The support cylinder 21 is used to connect to the base of the tunnel boring machine. The support cylinder 21 has a sliding cavity 211 defined therein. The guide seat 22 slides within the sliding cavity 211. The sliding seat 24 slides on the slideway 10. The two ends of the connecting rod 23 correspondingly connect the support cylinder 21 and the guide seat 22. The length of the connecting rod 23 is adjustable to change the support height of the support cylinders 21 in two adjacent adjustment assemblies 20, thereby changing the inclination angle of the tunnel boring machine in the tunneling direction.

[0027] Specifically, the slideway 10 is the foundational support structure for the entire slope adjustment system, extending along the tunneling direction and laid onto the tunnel floor. Multiple adjustment assemblies 20 are spaced along the slideway 10 along the tunneling direction. Each adjustment assembly 20 is responsible for adjusting the attitude of the tunneling machine body. They work together to precisely control the inclination angle of the tunneling machine body.

[0028] The sliding seat 24 slides on the slideway 10 and is the actuator for the movement of the adjustment assembly 20 on the slideway 10. The support cylinder 21 is the portion of the adjustment assembly 20 that is directly connected to the tunnel boring machine. It connects to the tunnel boring machine's base and provides stable support for the machine. The sliding movement of the guide seat 22 within the sliding cavity 211 is driven by the connecting rod 23. The guide seat 22 moves up and down within the sliding cavity 211 according to the length of the connecting rod 23, thereby driving the corresponding lifting and lowering movement of the support cylinder 21.

[0029] During the process of adjusting the inclination angle of the tunnel boring machine, when the connecting rod 23 is extended, the support tube 21 moves upward, thereby increasing the height of the tunnel boring machine at the location where the adjustment assembly 20 supports it. When the connecting rod 23 is shortened, the support tube 21 moves downward, thereby decreasing the height of the tunnel boring machine at the location where the adjustment assembly 20 supports it. In other words, by adjusting the length of the connecting rod 23 in each adjustment assembly 20, the inclination angle of the tunnel boring machine in the direction of tunnel excavation can be changed to meet the excavation needs under different geological conditions and construction requirements.

[0030] In summary, the slope adjustment device of the tunnel boring machine provided by the present invention can accurately control the body posture of the tunnel boring machine, ensure that the excavation is strictly carried out along the center waistline, and help improve the operating efficiency of the equipment in undulating tunnels.

[0031] like Figure 1 、 Figure 2 and Figure 3As shown, in some embodiments, the outer side of the support tube 21 is provided with a plurality of fixing ears 212. The fixing ears 212 can be fixed to the base of the multi-purpose excavator by welding, bolts, or other structures, so that the support tube 21 is firmly mounted on the multi-purpose excavator, providing a stable support foundation for the entire mechanical system. In this embodiment, the fixing ears 212 are fixed to the base of the multi-purpose excavator by a bolt structure.

[0032] like Figure 4 As shown, in some embodiments, two opposing guide grooves 213 are provided within the support cylinder 21. A plurality of guide wheels 221 are rotatably mounted on the guide seat 22. Each guide wheel 221 corresponds to each guide groove 213 and rolls within the guide groove 213, thereby reducing frictional resistance and making the guide seat 22 slide more easily and efficiently. Furthermore, due to the tight fit between the guide wheels 221 and the guide groove 213, the guide seat 22 maintains a stable motion trajectory during sliding, preventing side-to-side swinging or up-and-down bouncing. This ensures accurate and stable posture adjustment of the tunnel boring machine body. In this embodiment, two guide wheels 221 are provided.

[0033] like Figure 1 、 Figure 2 and Figure 5 As shown, in some embodiments, the cross-section of the slide 10 is set to be Ω-shaped, and the slide 10 has an arcuate surface 11, a first supporting surface 12 and a second supporting surface 13, and the first supporting surface 12 and the second supporting surface 13 are respectively arranged on both sides of the arcuate surface 11, and a plurality of pulleys 241 are provided in the sliding seat 24, and the pulleys 241 are arranged in a one-to-one correspondence with the arcuate surface 11, the first supporting surface 12 and the second supporting surface 13.

[0034] The curved surface 11 is located at the top center of the slide 10 and is a smooth and continuous curved surface. The first support surface 12 and the second support surface 13 are respectively arranged on both sides of the curved surface 11. They smoothly transition with the curved surface 11 to form a stable support structure. The first support surface 12 and the second support surface 13 provide additional support for the sliding seat 24, thereby enhancing the overall load-bearing capacity of the slide 10. In actual applications, the tunnel boring machine will generate large vibrations and impact forces during the excavation process. The first support surface 12 and the second support surface 13 can effectively disperse these forces to prevent the slide 10 from being deformed or damaged due to uneven force.

[0035] In this embodiment, the sliding seat 24 has a cross-section that is compatible with sliding, allowing the sliding seat 24 to engage with the slideway 10. The Ω-shaped cross-section also reduces the risk of derailment between the sliding seat 24 and the slideway 10. Furthermore, the pulley 241 includes a first wheel 2411 and a second wheel 2412. Multiple first wheels 2411 and second wheels 2412 are provided. Multiple first wheels 2411 are spaced apart and roll on the curved surface 11, while multiple second wheels 2412 roll on the first support surface 12 and the second support surface 13, respectively.

[0036] The first wheel 2411 is axially configured with a smaller center and larger ends, allowing it to better conform to the curved surface 11 of the Ω-shaped slideway 10. This creates a closer contact between the first wheel 2411 and the curved surface 11, reducing play and shaking during sliding. Furthermore, the structure of the first wheel 2411 improves its stability during rolling, preventing deviation or damage due to uneven force, thereby ensuring the normal operation and efficient performance of the entire sliding system.

[0037] Furthermore, a shock-absorbing rubber layer is provided on the sliding seat 24, which is located on the side of the sliding seat 24 facing the slide 10. The shock-absorbing rubber layer is used to reduce the vibration and noise generated when the sliding seat 24 slides on the slide 10, thereby ensuring the overall stability of the tunnel boring machine.

[0038] In some embodiments, the slope adjustment device also includes a braking assembly, which includes a length-adjustable support rod and a brake block. The length-adjustable support rod is extended along the height direction of the tunnel boring machine. The two ends of the length-adjustable support rod are correspondingly connected to the sliding seat 24 and the brake block, and the brake block is used to abut the slideway 10.

[0039] That is, during the slope adjustment process, the operator can flexibly adjust the length of the adjustable support rod according to the desired fixed position and posture of the tunnel boring machine, so that the brake block can accurately abut against the slideway 10, thereby realizing the braking function. At the same time, the adjustable support rod also has a certain degree of rigidity and elasticity, which can withstand the braking force while providing a certain buffering effect on vibration and impact, thereby reducing damage to the slope adjustment device and the tunnel boring machine.

[0040] Optionally, the brake pad is usually made of a wear-resistant, high-friction material, such as rubber, polyurethane, or a composite friction material. These materials have good elasticity and wear resistance, can maintain stable friction performance during long-term friction with the slide 10, and reduce wear on the surface of the slide 10.

[0041] Optionally, the length-adjustable support rod can be configured as a hydraulic rod or an electric rod.

[0042] like Figure 3As shown, in some embodiments, the adjustment assembly 20 includes a first rotating shaft 25 and a second rotating shaft 26, both extending in the tunneling direction. The first rotating shaft 25 is rotatably connected between the support tube 21 and the connecting rod 23, while the second rotating shaft 26 is rotatably connected between the guide seat 22 and the sliding seat 24. During the slope adjustment process, when the inclination angle of the tunnel boring machine body needs to be changed, the length of the connecting rod 23 changes. In this case, the first rotating shaft 25 allows relative rotation between the support tube 21 and the connecting rod 23 to accommodate the angle change caused by the length change of the connecting rod 23. For example, when the connecting rod 23 extends, the support tube 21 rotates upward relative to the connecting rod 23 by a certain angle; when the connecting rod 23 shortens, the support tube 21 rotates downward. This relative rotation allows the support tube 21 to accurately adjust its support height, thereby achieving precise control of the inclination angle of the tunnel boring machine body.

[0043] Due to the unevenness of the roadway floor and the dynamic changes caused by the slope adjustment operation, the guide seat 22 and the sliding seat 24 may be subjected to forces and moments in different directions. In this case, the second rotating shaft 26 can enable the guide seat 22 and the sliding seat 24 to rotate relative to each other according to the actual situation to adapt to these changes in forces and moments, thereby ensuring the overall stability and movement flexibility of the adjustment assembly 20.

[0044] For example, when the sliding seat 24 slides on the slideway 10, if it encounters a slight undulation or inclination on the surface of the slideway 10, the sliding seat 24 may tilt at a certain angle. In this case, the second rotating shaft 26 can cause the guide seat 22 to rotate accordingly relative to the sliding seat 24, so that the guide seat 22 always maintains a good fit with the guide groove 213 in the support tube 21, ensuring that the guide seat 22 can slide smoothly and steadily within the support tube 21.

[0045] The first rotating shaft 25 and the second rotating shaft 26 cooperate with each other to form the movement hub of the adjustment assembly 20. During the slope adjustment process of the tunnel boring machine, when the length of the connecting support rod 23 changes, the first rotating shaft 25 causes the support cylinder 21 and the connecting support rod 23 to rotate relative to each other, adjusting the support height of the support cylinder 21; at the same time, the second rotating shaft 26 causes the guide seat 22 and the sliding seat 24 to rotate relative to each other to adapt to the impact of the position changes of the support cylinder 21 and the guide seat 22, ensuring the normal sliding of the guide seat 22 within the support cylinder 21. This synergistic effect allows the adjustment assembly 20 to flexibly respond to various slope adjustment requirements, ensuring accurate and stable adjustment of the inclination angle of the tunnel boring machine body, and providing a strong guarantee for the efficient and safe conduct of tunnel excavation operations.

[0046] In this embodiment, the adjustment assembly 20 further includes a coupling seat 27, which is mounted to the top of the sliding cavity 211 within the support tube 21. The coupling seat 27 is provided with a first through-hole 271, through which the first rotating shaft 25 is passed. The connecting rod 23 has a fixed end 231 and a movable end 232. The fixed end 231 of the connecting rod 23 is connected to the first rotating shaft 25, and the telescopic end of the connecting rod 23 is connected to the guide seat 22.

[0047] The sliding base 24 includes a first support 242 and a second support 243 connected to each other. The first support 242 can be fixed to the second support 243 via welding, bonding, or bolting. The sliding wheel is rotatably mounted on the second support 243. The guide base 22 has a groove 222 on a side away from the connecting rod 23. The second rotating shaft 26 is rotatably mounted within the groove 222. The first support 242 has two connecting ears 244, each of which has a second through hole. The second rotating shaft 26 is rotatably mounted within the second through hole.

[0048] Furthermore, the adjustment component 20 also includes multiple angle sensors 28, which are correspondingly arranged on the first rotating shaft 25 and the second rotating shaft 26. The multiple angle sensors 28 are respectively used to monitor the rotation angle of the connecting support rod 23 relative to the support tube 21 and the rotation angle of the sliding seat 24 relative to the guide seat 22, so as to monitor the tilt posture of the tunnel boring machine in the left and right directions of the tunnel.

[0049] Specifically, the angle sensor 28 transmits the monitored rotation angle data to the slope adjustment device's control system in real time. Based on this data, combined with preset slope adjustment parameters and algorithms, the control system can quickly calculate the actual tilt angle and tilt direction of the tunnel boring machine. For example, if the rotation angle of the connecting rod 23 relative to the support tube 21 and the rotation angle of the sliding seat 24 relative to the guide seat 22 both indicate that the tunnel boring machine is tilting to the left, the control system will use this information to promptly adjust the relevant components of the slope adjustment device, such as changing the length of the connecting rod 23 or adjusting the position of the sliding seat 24 on the slideway 10, to correct the tunnel boring machine's tilt and restore it to a horizontal or preset tilt angle.

[0050] In this embodiment, the connecting support rod 23 can be set as a hydraulic support rod, and the slope adjustment device of the tunnel boring machine also includes a control component, which includes a controller 31, a hydraulic pump group 32 and multiple inclination sensors 33. The multiple inclination sensors 33 are respectively arranged at different positions of the base. The inclination sensor 33 is used to detect the inclination angle of the base. The controller 31 is electrically connected to the inclination sensor 33 and the hydraulic pump group 32. The controller 31 is used to control the hydraulic pump group 32 to supply oil to the hydraulic support rod of the slope adjustment device according to the detection data of the inclination sensor 33 to adjust the inclination angle of the body of the tunnel boring machine.

[0051] Specifically, during the slope adjustment operation of the tunnel boring machine, first, the inclination sensor 33 detects the inclination angle of the base in real time and transmits the data to the controller 31. The controller 31 processes and analyzes the data, calculating the length of the hydraulic support rod that needs to be adjusted and the oil supply of the hydraulic pump group 32. Then, the controller 31 sends a control instruction to the hydraulic pump group 32. The hydraulic pump group 32 supplies oil to the hydraulic support rod according to the instruction, causing the hydraulic support rod to extend and retract, thereby adjusting the inclination angle of the tunnel boring machine body. During the adjustment process, the inclination sensor 33 continuously monitors the inclination angle of the base and feeds back the new data to the controller 31, forming a closed-loop feedback control system. The controller 31 continuously adjusts the oil supply parameters of the hydraulic pump group 32 based on the feedback data until the inclination angle of the tunnel boring machine body reaches the preset target value.

[0052] In some embodiments, the connecting support rod 23 may also be configured as an electric support rod, which has a similar working process to that of the hydraulic support rod embodiment and will not be described in detail here.

[0053] Of course, in some embodiments, the control component can also combine the data monitored by the angle sensor 28 to obtain the inclination state of the tunnel boring machine in the left and right directions of the tunnel, and adjust the extension and retraction of the connecting support rod 23 in the adjustment component 20 on the two adjacent slides 10 to achieve the posture adjustment of the tunnel boring machine in the left and right directions of the tunnel.

Furthermore, one embodiment of the present invention provides a tunneling system, comprising a transfer machine and the tunnel boring machine provided in the above-mentioned embodiments, with a slideway 10 connected to the transfer machine. The tunneling system comprises at least two slideways 10, and the posture of the tunnel boring machine in the left-right direction of the tunnel is adjusted by extending and retracting the connecting rods 23 within the adjustment assemblies 20 of two adjacent slideways 10.
