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 particular embodiments. Detailed Implementation

[0047] As described in the background section, in related technologies, tunneling devices include cutterheads, which are typically circular, resulting in a circular tunnel cross-section. However, circular tunnels have low cross-sectional utilization and dead corners on both sides. If the tunnel is to be converted into an arched tunnel, secondary construction of the original circular tunnel is required.

[0048] In view of this, the embodiments of this application, by setting two first and second cutter discs with opposite cutting directions, can more effectively crush rocks and soil, reduce vibration, and improve cutting efficiency; the combined design of the discharge section and the drum allows the cut material to be quickly and smoothly transported to the discharge port, reducing the impact of material accumulation on tunneling efficiency; by designing the drum, secondary construction of circular tunnels can be avoided, improving the working efficiency of the tunneling machine and reducing project costs.

[0049] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0050] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0051] refer to Figure 1 This application provides a tunneling device, including a partition plate 100, a first cutterhead 200, a second cutterhead 300, and a drum 400.

[0052] The partition 100 is provided with a discharge port 110.

[0053] The first cutter head 200 and the second cutter head 300 are coaxially arranged on the partition plate 100, and the cutting direction of the first cutter head 200 is opposite to that of the second cutter head 300.

[0054] At least one of the first cutter head 200 and the second cutter head 300 is provided with a discharge section 310, which is used to discharge material to the discharge port 110.

[0055] The roller 400 is rotatably mounted on the partition 100. The rotation axis of the roller 400 is not parallel to the rotation axis of the first cutter head 200. The roller 400 is used at least to discharge material to the discharge section 310.

[0056] It is understood that the partition plate 100 plays a supporting and separating role in the entire device, and is provided with a discharge port 110 for discharging the cut rock or soil. The first cutter head 200 and the second cutter head 300 cut in opposite directions. When the first cutter head 200 and the second cutter head 300 rotate, they apply shear stress to the rock and soil. Since the first cutter head 200 and the second cutter head 300 rotate in opposite directions, the shear stress they apply is also opposite. This opposite shear stress can cancel each other out, thereby reducing the net shear force borne by the entire tunneling device. The overall stress of the tunneling device is more uniform. This uniform stress state reduces the situation of excessive stress on one side, reduces the wear and failure risk of the equipment, and makes the tunneling device more stable during operation, reducing vibration and shaking, which helps to improve cutting efficiency and accuracy, and also improves operational safety. The discharge section 310 is responsible for guiding the cut material to the discharge port 110, which can effectively manage and transport the cut material and avoid material accumulation during tunneling. The roller 400 can assist in material gathering while cutting.

[0057] It should be noted that the first cutter head 200 can be a central cross cutter head. A central cross cutter head usually has a cross-shaped layout. This design can provide stronger cutting capability in the central area of ​​the cutter head. The cross-shaped structure helps to disperse and evenly distribute cutting forces, reducing the situation of excessive force at a single point.

[0058] The second cutterhead 300 can be a plate-type cutterhead, which typically has a flat plate structure with multiple cutting tools distributed on its surface, providing a large cutting contact area during tunneling. The tools on the cutterhead are usually arranged in a specific geometric pattern to optimize the cutting path and efficiency. The tool arrangement can be radial, helical, or other geometric shapes to adapt to different geological conditions. Through its large-area flat plate structure and optimized tool arrangement, the plate-type cutterhead achieves high-efficiency cutting capability, enabling the tunneling machine to quickly break rocks and soil and increase tunneling speed. Due to the flat plate structure of the cutterhead, the cutting force can be distributed more evenly across the entire cutterhead, reducing local stress concentration and lowering the wear and failure risk of the cutterhead.

[0059] The combination of the first cutterhead 200 and the second cutterhead 300 enables the tunneling device to not only have a strong tunneling capability but also to be assisted by a uniform large-area cutting capability, thereby improving the working efficiency of the tunneling device.

[0060] In some embodiments, the drum 400 has evenly distributed tunneling teeth 401 on its cylinder wall. Since the second cutterhead 300 is a plate cutterhead, there are cutting dead angles at its lower left and right corners. The tunneling teeth 401 are used to crush the rocks and soil located at the lower left and right corners of the second cutterhead 300 when the tunneling device moves forward. They can also roll the debris generated at the lower left and right corners of the second cutterhead 300 upwards into the discharge section 310 to assist the tunneling device in discharging material.

[0061] By setting two cutterheads 200 and 300 with opposite cutting directions, rocks and soil can be broken more effectively, vibration can be reduced, and cutting efficiency can be improved. The combined design of the discharge section 310 and the drum 400 allows the cut material to be quickly and smoothly transported to the discharge port 110, reducing the impact of material accumulation on tunneling efficiency. By designing the drum 400, secondary construction of circular tunnels can be avoided, thereby reducing project costs.

[0062] In some possible implementations, the tunneling device includes a drive shaft 500, which is coaxially connected to the first cutterhead 200.

[0063] The drive shaft 500 is provided with a connector, and the drive shaft 500 drives the second cutter head 300 to rotate through the connector. The rotation direction of the first cutter head 200 is opposite to the rotation direction of the second cutter head 300.

[0064] It is known that the drive shaft 500 is coaxially connected to the first cutter head 200 and is responsible for transmitting power to drive the first cutter head 200 to rotate. The coaxial connection design of the drive shaft ensures the efficiency and stability of power transmission. The connector is used to transmit the power of the drive shaft 500 to the second cutter head 300. In this way, the drive shaft 500 can not only drive the first cutter head 200, but also drive the second cutter head 300 through the connector.

[0065] Through the coaxial connection design of the drive shaft 500, power can be efficiently transmitted to the first cutterhead 200, reducing energy loss and improving the overall efficiency of the tunneling device. By setting the connecting parts, the drive shaft 500 can transmit power to the second cutterhead 300, realizing the coordinated work of multiple cutterheads. The tunneling device can more efficiently crush and cut rocks and soil, thereby improving tunneling efficiency and reducing construction time and costs.

[0066] In some possible implementations, the tunneling device includes a transmission assembly.

[0067] The input end of the transmission component is connected to the drive shaft 500, and the output end of the transmission component is connected to the roller 400.

[0068] What we know is that the function of the transmission assembly is to transmit the power of the drive shaft 500 to the drum 400, so that the drum 400 can operate effectively.

[0069] Through the design of the transmission components, the drum 400 can obtain a stable and efficient power source, thereby improving the efficiency of material cutting and conveying, and ensuring that the cut rocks and soil can be quickly cleared; the direct connection design of the transmission components reduces energy loss in intermediate links, improves the efficiency of power transmission, and enables the entire tunneling device to operate more efficiently.

[0070] In some possible implementations, the transmission assembly includes a first bevel gear 610 and a second bevel gear 620, the first bevel gear 610 being connected to the drive shaft 500, and the rotation axis of the first bevel gear 610 being parallel to the drive shaft 500.

[0071] The second bevel gear 620 meshes with the first bevel gear 610, the second bevel gear 620 is connected to the roller 400, and the rotation axis of the second bevel gear 620 is perpendicular to the rotation axis of the first bevel gear 610.

[0072] It is known that the first bevel gear 610 is responsible for transmitting the rotational motion of the drive shaft 500 to the second bevel gear 620; the second bevel gear 620 is connected to the roller 400 and is responsible for transmitting power to the roller 400; since the rotation axis of the second bevel gear 620 is perpendicular to the first bevel gear 610, a 90° change in the direction of power is achieved, enabling the roller 400 to operate in a direction perpendicular to the drive shaft 500.

[0073] The meshing design of the first bevel gear 610 and the second bevel gear 620 enables the conversion of power between different axes, allowing the drum 400 to operate efficiently in a direction different from the drive shaft 500, adapting to complex mechanical layout requirements. The meshing design of the first bevel gear 610 and the second bevel gear 620 ensures efficient power transmission, reduces energy loss, and improves the driving efficiency of the drum 400. The vertical meshing bevel gear design allows for complex power transmission paths within a limited space, optimizing the overall structural layout of the tunneling device, reducing its size, improving the compactness of the equipment, and providing more flexibility for the arrangement of other components.

[0074] In some possible implementations, there are multiple transmission components, including a first transmission component and a second transmission component.

[0075] There are multiple rollers 400, including a first roller 410 and a second roller 420.

[0076] The drive shaft 500 drives the first roller 410 to rotate through the first transmission assembly, and the drive shaft 500 drives the second roller 420 to rotate through the second transmission assembly.

[0077] In some embodiments, the first roller 410 and the second roller 420 are distributed in a vertical direction, with the first roller 410 located above or below the second roller 420; there are two sets of the first roller 410 and the second roller 420, and the two sets of the first roller 410 and the second roller 420 are stacked and distributed on both sides of the tunneling device.

[0078] It is known that the first drum 410 can be located above or below the second drum 420, and this flexible arrangement allows for adjustments based on specific construction needs and equipment design. Two sets of first drums 410 and second drums 420 are stacked and distributed on both sides of the tunneling device. This symmetrical arrangement helps balance the forces on the equipment and reduce eccentric loads. Multiple transmission components are used to transmit power from the drive shaft 500 to different drums 400. The drive shaft 500 drives the first drum 410 to rotate via the first transmission component and drives the second drum 420 to rotate via the second transmission component, ensuring that each drum 400 can operate independently and efficiently.

[0079] The design of multiple rollers 400 improves the overall material gathering capacity of the tunneling device; the design of multiple transmission components allows each roller 400 to operate independently as needed, improving the system's flexibility and adaptability; since multiple rollers 400 can operate simultaneously, the cutting and auxiliary material gathering processes are more continuous and efficient, reducing equipment downtime caused by material accumulation.

[0080] In some possible embodiments, the first roller 410 and the second roller 420 can be detachably connected on the drive shaft of the second bevel gear 620.

[0081] The connection between the first drum 410 and the second drum 420 and the drive shaft of the second bevel gear 620 is usually made of bolts, clips or other mechanical fasteners to facilitate installation and disassembly; the detachable connection allows the first drum 410 and the second drum 420 to be easily disassembled and replaced, reducing maintenance time and complexity and improving the maintainability of the equipment; the tunneling device can replace different types of drums according to different construction needs to adapt to different geological conditions and construction requirements.

[0082] In some possible implementations, the connecting element includes a cooperating drive gear 710 and a driven gear 720.

[0083] The driving gear 710 is coaxially arranged with the drive shaft 500, and the driven gear 720 is rotatably arranged on the partition 100. The driven gear 720 meshes with the driving gear 710, and the driven gear 720 is used to drive the second cutter head 300 to rotate around the drive shaft 500.

[0084] The drive gear 710 is coaxially arranged with the drive shaft 500 and directly obtains power from the drive shaft 500. Due to the coaxial arrangement, the drive gear 710 can efficiently transmit the rotational motion of the drive shaft to the driven gear 720. The drive gear 710 drives the driven gear 720, and the driven gear 720 transmits power to the second cutter head 300, causing it to rotate around the drive shaft 500.

[0085] Through the meshing design of the drive gear 710 and the driven gear 720, power can be efficiently transmitted from the drive shaft 500 to the second cutter head 300, reducing energy loss and improving cutting efficiency. Through the cooperative arrangement of the drive gear 710 and the driven gear 720, the first cutter head 200 and the second cutter head 300 can achieve the motor performance of opposite cutting directions. Due to the simple mechanical structure, it is suitable for long-term operation and is easy to maintain.

[0086] refer to Figure 2 At least two driven gears 720 are provided, and the two driven gears 720 mesh around the outer periphery of the driving gear. The driven gears 720 perform circular motion around the driving gear 710 as the center. Taking the counterclockwise rotation of the driving gear 710 as an example, when the driving gear 710 is driven to rotate counterclockwise by the drive shaft 500, the driven gears 720 rotate clockwise around their central axis. At this time, the first cutter head 200 rotates counterclockwise and the second cutter head 300 rotates clockwise.

[0087] In some possible implementations, a coaxial first spur gear 630 is provided on the drive shaft 500. The first transmission assembly includes a first bevel gear 610, a second bevel gear 620, a second spur gear 640, and a first transmission shaft 650. The second spur gear 640 is coaxially connected to the first bevel gear 610 of the second transmission assembly on the first transmission shaft 650. The first spur gear 630 meshes with the second spur gear 640. The first bevel gear 610 of the first transmission assembly meshes with the second bevel gear 620 on the first roller 410.

[0088] The second transmission assembly includes a first bevel gear 610, a second bevel gear 620, a third spur gear 660, and a second transmission shaft 670. The third spur gear 660 is coaxially connected to the first bevel gear 610 of the second transmission assembly on the second transmission shaft 670. The third spur gear 660 meshes with the second spur gear 640. The first bevel gear 610 of the second transmission assembly meshes with the second bevel gear 620 on the second roller 420.

[0089] refer to Figures 3-4By setting a first spur gear 630, a second spur gear 640, and a third spur gear 660, the power of the drive shaft 500 can be transmitted to the first transmission shaft 650 and the second transmission shaft 670. During use, the drive shaft 500 rotates, causing the first spur gear 630 to drive the second spur gear 640 to rotate, thereby causing the first bevel gear 610 on the first transmission shaft 650 to rotate. Since the rotation axis of the second bevel gear 620 is perpendicular to the first transmission shaft 650, the rotation direction of the first drum 410 is perpendicular to the rotation direction of the first cutter head 200 and the second cutter head 300, enabling the tunneling teeth 401 of the drum wall to contact the rock wall and soil in the forward direction of the tunneling device for cutting and material gathering.

[0090] The second spur gear 640 drives the third spur gear 660 to rotate, thereby causing the first bevel gear 610 on the second drive shaft 670 to rotate. Since the rotation axis of the second bevel gear 620 is perpendicular to the second drive shaft 670, the rotation direction of the second drum 420 is perpendicular to the rotation direction of the first cutter head 200 and the second cutter head 300, enabling the tunneling teeth 401 of the drum wall to contact the rock wall and soil in the forward direction of the tunneling device for cutting and material gathering.

[0091] By combining spur gears and bevel gears, power can be efficiently transmitted from the drive shaft to the drum 400, reducing energy loss and improving transmission efficiency. The design of the two transmission components allows for flexible distribution of power to different drums 400. Through reasonable gear meshing and drive shaft configuration, the entire system is subjected to more uniform force, reducing vibration and wear, and improving the stability and reliability of the equipment.

[0092] In some possible implementations, the first drive shaft 650 has a first bevel gear 610 at both ends, and the gears of the two first bevel gears 610 face opposite directions, so that the first drive shaft 650 can be symmetrically connected to the first roller 610 at both ends through a second bevel gear 620.

[0093] Both ends of the second drive shaft 670 have first bevel gears 610. The gears of the two first bevel gears 610 face opposite directions, so that both ends of the second drive shaft 670 can be symmetrically connected to the second roller 420 through the second bevel gears 620.

[0094] refer to Figure 5 In some possible implementations, the tunneling device also includes an adjustment assembly, which includes a base 810 and an adjustment member 820.

[0095] The base 810 is connected to the partition 100.

[0096] The first end of the adjusting member 820 is rotatably connected to the base 810, and the second end of the adjusting member 820 is connected to the partition 100. The second end of the adjusting member 820 is used to drive the partition 100 to rotate.

[0097] It is known that the adjustment component is used to adjust the working angle and position of the tunneling device; the base 810 is connected to the partition 100, providing a fixed support point for the adjustment component.

[0098] By adjusting the design of the components, the tunneling device can flexibly adjust the working angles of the first cutterhead 200 and the second cutterhead 300 to adapt to different geological conditions and construction requirements. This flexibility helps to improve cutting efficiency and effectiveness. By adjusting the angle of the partition 100, the tunneling device can achieve tunnel cross-sections of different shapes, such as arched tunnels, reducing the reliance on circular tunnels and lowering the need for secondary construction and project costs.

[0099] refer to Figure 6 In some possible implementations, the adjustment assembly includes a guide rod 830, the first end of which is rotatably connected to the base 810, and the second end of which is rotatably connected to the partition 100.

[0100] It is known that the first end of the guide rod 830 is rotatably connected to the base 810, which means that the guide rod can rotate around the connection point of the base 810; the second end of the guide rod 830 is rotatably connected to the partition plate 100, which also allows the guide rod 830 to rotate around the connection point of the partition plate 100; through the rotatable connection of the two ends of the guide rod 830 to the base 810 and the partition plate 100, the adjustment assembly can flexibly adjust the angle and position of the first cutterhead 200 and the second cutterhead 300 of the tunneling device, thereby adjusting the roadway slope.

[0101] The rotating connection design of the guide rod 830 allows the tunneling machine to flexibly adjust the angle and position of the first cutterhead 200 and the second cutterhead 300 through a simple mechanical structure; through reasonable adjustment and support, the guide rod 830 can help maintain the stability of the tunneling device, reduce vibration and unnecessary movement, and improve cutting accuracy.

[0102] The guide rod 830 can be a hydraulic cylinder, which can provide powerful thrust and precise control; alternatively, the guide rod 830 can be an electric push rod, which uses a motor to drive a screw for linear motion.
