[0002] Full-face tunnel boring machines (TBMs) integrate rock breaking, muck removal, slag discharge, and support functions, allowing each process to work in coordination. They are currently the most technologically advanced tunnel boring equipment in the world. The TBM muck removal system is one of the key systems, and its smooth operation directly affects the TBM's construction efficiency.

[0003] Traditional TBM muck chute system designs are ill-suited for handling steep longitudinal slopes during tunneling. Conventional TBM muck chute systems consist of the cutterhead body, the muck chute channel within the cutterhead body, and the muck chute plate. The muck chute plate has a fixed structure and cannot be adjusted. Under steep uphill or downhill conditions, muck can easily accumulate between the muck chute plate and the muck chute channel, leading to obstructed muck chute flow. Utility Model Content

[0042] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. 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

[0043] 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.

[0044] First, let me explain the terms used in this application:

[0045] A tunnel boring machine (TBM) is a heavy-duty machine used for tunnel excavation in underground engineering. Based on application scenarios and structural characteristics, TBMs are mainly divided into two categories: full-face rock tunnel boring machines (TBMs) and shield tunneling machines. TBMs are specifically designed for hard rock formations and use a rotating cutterhead to complete the full-face excavation in one pass. They are further divided into open-face and shield types.

[0046] Tunnel boring machines (TBMs) are mainly used in soft soil or complex strata. They are equipped with shield structures to support the excavation face in real time. According to the balancing method, they can be divided into earth pressure balance TBMs and slurry balance TBMs.

[0047] As described in the background art, a tunneling machine is a comprehensive piece of equipment that performs continuous operations by mechanically breaking rocks, removing slag, and providing support. The cutterhead assembly breaks up the rock, and then the slag, under the action of the bucket assembly 200, enters the slag chute 110 through the slag inlet 111. In the prior art, the slag chute 300 is generally fixedly installed at the bottom of the slag chute 110 and at a certain angle to the slag chute 110. The slag entering the slag chute 110 falls onto the slag chute 300. Due to the inclined installation of the slag chute 300, the slag moves in a certain direction under the action of gravity and is eventually completely discharged from the slag chute 110, thus realizing the slag removal process.

[0048] However, since the tilt angle of the chute 300 in the existing technology cannot be adjusted, when encountering a steep uphill or downhill slope, the angle between the chute 300 and the vertical direction will change. When the angle between the chute 300 and the vertical direction is 90 degrees, after the slag falls on the chute 300, the slag cannot slide out of the chute channel 110 by its own weight, resulting in slag accumulation. Or when the angle between the chute 300 and the vertical direction is close to 90 degrees, some slag will also be unable to slide out of the chute channel 110 by its own weight, resulting in poor slag chute handling.

[0049] To address the aforementioned technical problems, this application provides a muck chute system for a tunneling machine and the tunneling machine itself. The muck chute 300 and the cutterhead body 100 are rotatably connected. During steep uphill or downhill slopes, muck enters the muck chute 110. Since the angle between the muck chute 300 and the cutterhead body 100 is adjustable, the muck chute 300 always maintains an angle with the horizontal. The muck entering the muck chute 110 falls onto the inclined muck chute 300, and then, under its own weight, flows out of the muck chute 110 along the muck chute 300. This ensures that all muck entering the muck chute 110 is discharged from the muck chute 110 under the action of the muck chute 300, avoiding muck accumulation and obstructed muck chute flow.

[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] like Figure 1 and Figure 2As shown, this embodiment provides a muck chute system for a tunneling machine, including: a cutterhead body 100, a bucket assembly 200, and a muck chute plate 300; wherein the cutterhead body 100 has at least one muck chute channel 110 inside; the cutterhead body 100 has a muck inlet 111 at one end of the muck chute channel 110, and a muck outlet 112 at the other end of the muck chute channel 110; wherein the bucket assembly 200 is disposed on the cutterhead body 100; the bucket assembly 200 is adapted to allow muck to enter the muck chute channel 110 through the muck inlet 111; wherein the muck chute plate 300 is disposed in the muck chute channel 110, and the muck chute plate 300 is adapted to be rotatably connected to the cutterhead body 100; the muck chute plate 300 is adapted to receive the muck entering the muck chute channel 110 and change the direction of movement of the muck.

[0052] Specifically, there are six muck chute 110s shown in the attached drawings of this embodiment, and the six muck chute 110s are evenly distributed on the cutterhead body 100. The number of bucket assemblies 200 corresponds to the number of muck chute 110s, and the bucket assemblies 200 are located near the entrance of the muck chute 110. The bucket assemblies 200 are common components of tunneling machines. The bucket assemblies 200 can collect the muck towards the entrance of the muck chute 110, and then the muck will enter the muck chute 110. The six bucket assemblies 200 provided on the cutterhead body 100 can ensure that the muck during the working process enters the muck chute 110. The cutterhead body 100 is also provided with necessary components of the tunneling machine, such as cutters and cutter holders.

[0053] As an alternative implementation, the number of slag chute 110 can be further increased or decreased, for example, to four or eight. Increasing the number of slag chute 110 can further ensure that all slag can enter the slag chute 110, while reducing the number of slag chute 110 can reduce equipment costs. The specific choice can be made according to actual needs.

[0054] In this embodiment, the slag chute 300 and the cutterhead body 100 are rotatably connected. When the slag enters the slag chute 110 on a steep uphill or downhill slope, the angle between the slag chute 300 and the cutterhead body 100 can be adjusted so that the slag chute 300 always has an angle with the horizontal direction. This ensures that the slag entering the slag chute 110 is completely discharged from the slag chute 110 under the action of the slag chute 300, avoiding slag accumulation and slag chute obstruction.

[0055] Furthermore, the slag chute system of the tunneling machine provided in this application embodiment also includes several support plates, which are disposed within the cutterhead body 100; the support plates are adapted to be fixedly connected to the cutterhead body 100, and the several support plates form a slag chute channel 110.

[0056] It should be noted that, in order to prevent soil from entering the gap between the chute plate 300 and the chute channel 110, a chute baffle 310 is provided at the end of the chute plate 300 away from the chute channel 110. The end of the chute baffle 310 is hinged to the chute plate 300 by a pivot. Under the action of gravity, the chute baffle 310 hangs down naturally and always remains in a vertical state. This ensures that the chute baffle 310 can prevent soil from entering the gap between the chute plate 300 and the chute channel 110 when the tunneling machine is in different postures, thus avoiding the accumulation of soil.

[0057] In this embodiment, the number of support plates is a multiple of four, forming a square slag chute 110. This method effectively reduces costs and simplifies construction. The slag inlet 111 and outlet 112 of the slag chute 110 are also square. It should be noted that the number of support plates and the shape of the slag chute 110 can be modified according to actual needs. For example, three support plates can form a triangular slag chute 110, or five support plates can form a polygonal slag chute 110. The support plates are fixedly connected by welding, ensuring that the slag chute 110 formed by the multiple support plates has no obvious gaps to prevent slag leakage. The support plates are also fixedly connected to the cutterhead body 100 by welding or bonding.

[0058] like Figure 3 As shown, further, the chute system of the tunneling machine provided in this embodiment of the application also includes a first adjustment component 400, which is disposed within the chute channel 110; the first adjustment component 400 is connected to the chute plate 300, and is adapted to adjust the angle between the chute plate 300 and the chute channel 110. In this embodiment, the angle between the chute plate 300 and the cutterhead body 100 is realized through the first adjustment component 400, achieving automatic angle adjustment without stopping the machine to adjust the structure; under the control of the tunneling machine system, the chute system can achieve adaptive adjustment matching the tunneling posture, meeting the chute discharge requirements of different inclination tunneling postures.

[0059] Specifically, the slag chute system for a tunneling machine provided in this application embodiment includes a first adjustment component 400 comprising a first driving member 410 and a first cam structure 420; wherein the first cam structure 420 is adapted to connect with the first driving member 410; the first driving member 410 drives the first cam structure 420 to rotate; the first cam structure 420 is adapted to abut against the slag chute plate 300; and during the rotation of the first cam structure 420, it is adapted to adjust the angle between the slag chute plate 300 and the slag chute channel 110. Cam rotation has significant advantages in terms of precise control, compact structure, high reliability, and high efficiency.

[0060] It should be noted that the first driving component 410 is generally a motor, etc., and an angle sensor is set inside the motor to detect and control the rotation angle, thereby controlling the rotation angle of the first cam structure 420. The output end of the first cam structure 420 and the first driving component 410 are connected through a common transmission shaft. When the first driving component 410 rotates, it drives the first cam to rotate synchronously through the transmission shaft, thereby indirectly controlling the rotation angle of the first cam through the angle sensor.

[0061] A pin seat is provided inside the slag chute 110. The pin seat is fixed to the bottom of the slag chute 110 by welding. The slag chute 300 is connected to the pin seat by a pin, so as to realize the rotatable connection between the slag chute 300 and the slag chute 110. The rotatable connection between the slag chute 300 and the slag chute 110 by a pin shaft has the advantages of simple structure, strong load-bearing capacity, high reliability and good economy.

[0062] In practical implementation, when it is necessary to increase the angle between the slag chute 300 and the slag chute channel 110, the first driving member 410 drives the first cam structure 420 to rotate, gradually bringing the edge of the cam in the first cam structure 420 that is farther from the rotation center into contact with the slag chute 300, thereby indirectly increasing the distance between the slag chute 300 and the rotation center of the first cam structure 420. The slag chute 300 will swing upward, thus increasing the angle between the slag chute 300 and the slag chute channel 110. Conversely, if it is necessary to decrease the angle between the slag chute 300 and the slag chute channel 110, the first driving member 410 drives the first cam structure 420 to rotate, gradually bringing the edge of the cam in the first cam structure 420 that is closer to the rotation center into contact with the slag chute 300, thereby indirectly decreasing the distance between the slag chute 300 and the rotation center of the first cam structure 420. The slag chute 300 will swing downward, thus decreasing the angle between the slag chute 300 and the slag chute channel 110.

[0063] It should be noted that the starting positions of the chute plate 300 and the chute channel 110 are within the normal angle range at which the chute plate 300 can chute when the tunneling machine is in normal working posture.

[0064] like Figure 4As shown, in an alternative implementation, at least one adjusting groove 430 is provided in the slag chute 110; the first adjusting component 400 includes an adjusting bolt 440, which is fixedly connected to the slag chute 300; the adjusting bolt 440 has an adjusting state and a locked state. When the adjusting bolt 440 is in the adjusting state, it is slidably disposed in the adjusting groove 430; when the adjusting bolt 440 is in the locked state, it is fixedly disposed in the adjusting groove 430. It should be noted that the adjusting groove 430 is arc-shaped, specifically representing a portion of the path of a point on the support plate during rotation. The length of the adjusting groove 430 can increase the range of rotation angles of the slag chute 300, and the specific length of the adjusting groove 430 can be adjusted according to actual needs. The chute connection has advantages such as high flexibility, easy installation, strong adaptability, and low cost.

[0065] In practice, the adjusting bolt 440 is fixedly connected to the slag chute 300 by welding. To simplify the welding process, the adjusting bolt 440 and the slag chute 300 are welded to steel plates respectively, thereby ensuring that the slag chute 300 rotates as the adjusting bolt 440 moves within the adjusting groove 430. The position of the adjusting bolt 440 within the adjusting groove 430 is generally adjusted manually. The slag chute 300 is rotatably connected to the slag chute channel 110 via a pin. To increase the stability of the slag chute 300, the number of adjusting grooves 430 and adjusting bolts 440 can be further increased. In this embodiment, there are four adjusting grooves 430 and four adjusting bolts 440.

[0066] like Figure 5 As shown, the chute system of the tunneling machine provided in this embodiment further includes a chute assembly 500, which is disposed on one side of the cutterhead body 100. The chute assembly 500 is suitable for receiving the slag from the chute outlet 112. Generally, the chute assembly 500 can be linked with the conveying equipment to realize the automatic collection and transfer of waste materials. The chute generated during the operation of the tunneling machine can be transported out by a belt conveyor through the chute assembly 500.

[0067] Furthermore, the chute system for the tunneling machine provided in this application embodiment includes a chute assembly 500 comprising a chute body 510 and a front inclined plate 520, wherein the chute body 510 has an internal accommodating space suitable for accommodating slag. The front inclined plate 520 is rotatably connected to the chute body 510 and is adapted to receive and change the falling direction of the slag. The slag flows out from the chute outlet 112 of the chute passage 110. Because the slag is far from the chute body 510, if the slag falls directly onto the chute body 510, it will cause a huge impact force on the conveyor belt inside the chute body 510. Under the action of the impact force, the conveyor belt is prone to damage, thereby increasing subsequent maintenance costs.

[0068] It should be noted that, in existing technology, the angle of the front inclined plate 520 is fixed. When encountering tunnels with steep uphill or downhill slopes, the excavated rock may fall directly onto the front inclined plate 520 without passing through it, potentially damaging the conveyor belt. To address this issue, the front inclined plate 520 can be rotated, ensuring that the excavated rock always falls onto it during tunnel operations with steep uphill or downhill slopes.

[0069] In practice, the front inclined plate 520 and the slag hopper body 510 are rotatably connected by a pin and a pin seat. The pin seat is welded to the opening of the slag hopper body 510's accommodating space, and the front inclined plate 520 is rotatably connected to the slag hopper body 510 by a pin. To prevent some slag from accumulating on the top of the slag hopper body 510 during the falling process, an inclined cover plate 540 is installed on the side wall of the slag hopper body 510 near the slag outlet 112. The inclined cover plate 540 is fixedly connected to the top of the side wall of the slag hopper body 510 by snap-fit ​​and welding. The inclined cover plate 540 is inclined towards the front inclined plate 520, and one side of the inclined cover plate 540 abuts against the inner wall of the slag hopper body 510, ensuring that all the slag flows out of the slag outlet 112 and enters the slag hopper body 510, minimizing slag accumulation.

[0070] It should be noted that, in order to ensure the path of the slag after it flows out of the slag outlet 112, a guide plate 120 is also provided inside the cutterhead body 100. The guide plate 120 is located between the slag outlet 112 and the slag hopper body 510. The guide plate 120 has a guiding function to ensure that the slag moves towards the slag receiving body after it flows out of the slag outlet 112. At least one guide plate 120 is provided between each slag outlet 112 and the slag hopper body 510. The guide plate 120 is fixed to the cutterhead body 100 by welding or bonding. The guide plate 120 is specifically an inclined plate. The inclination angle of the guide plate 120 can be reasonably designed according to the position of the slag hopper body 510.

[0071] Furthermore, the slag chute system of the tunneling machine provided in this application embodiment also includes a second adjustment component 530, which is fixedly connected to the slag hopper body 510; the second adjustment component 530 is adapted to adjust the angle between the front inclined plate 520 and the slag hopper body 510.

[0072] like Figure 6 and Figure 7As shown, assuming the tunneling machine is moving uphill to the left, if the angle of the front inclined plate 520 is not adjustable during a steep uphill slope, the angle between the rockfall path and the front inclined plate 520 will decrease, causing some rockfall to be unable to pass through the front inclined plate 520, thus damaging the conveyor belt. During a steep downhill slope, the angle between the rockfall path and the front inclined plate 520 will increase, increasing the friction between the rockfall and the front inclined plate 520, preventing the rockfall from being properly discharged and affecting the discharge efficiency. Because the angle between the slag falling path and the front inclined plate 520 will decrease when going uphill at a large angle, in this solution, the angle between the front inclined plate 520 and the slag hopper body 510 is increased by the second adjustment component 530 to ensure that the angle between the slag falling path and the front inclined plate 520 is within the normal slag chuting range. Because the angle between the slag falling path and the front inclined plate 520 will increase when going downhill at a large angle, in this solution, the angle between the front inclined plate 520 and the slag hopper body 510 is decreased by the second adjustment component 530 to ensure that the angle between the slag falling path and the front inclined plate 520 is within the normal slag chuting range.

[0073] Furthermore, in the slag chute system of the tunneling machine provided in this application embodiment, the second adjustment component 530 includes a second driving member 531 and a second cam structure 532. The second driving member 531 is fixedly connected to the slag hopper body 510; the second cam structure 532 is adapted to connect with the second driving member 531; the second driving member 531 drives the second cam structure 532 to rotate; the second cam structure 532 is adapted to abut against the front inclined plate 520; during the rotation of the second cam structure 532, it is adapted to adjust the angle between the front inclined plate 520 and the slag hopper body 510. Cam rotation has significant advantages in terms of precise control, compact structure, high reliability, and high efficiency.

[0074] It should be noted that the second driving component 531 is generally a motor, etc., and an angle sensor is installed inside the motor to detect and control the rotation angle, thereby controlling the rotation angle of the second cam structure 532. The output end of the second cam structure 532 and the second driving component 531 are connected through a common drive shaft. When the second driving component 531 rotates, it drives the second cam to rotate synchronously through the drive shaft, thereby indirectly controlling the rotation angle of the second cam through the angle sensor. The outer surface of the second cam structure 532 abuts against the front inclined plate 520. During the rotation of the second cam, the position of the front inclined plate 520 from the center of the cam changes, realizing the up-and-down swing of the front inclined plate 520.

[0075] In this embodiment, the working angle between the plane of the front inclined plate 520 and the vertical direction is θ. This angle is adjusted by the second adjustment component 530 to ensure that the front inclined plate 520 maintains the working angle θ under different postures of the tunneling machine. The range of angle θ is the range within which the front inclined plate 520 can receive excavated soil.

[0076] On the other hand, this embodiment provides a tunneling machine, including a tunneling machine body and a chute system for the tunneling machine disposed on the tunneling machine body.
