[0021] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0022] The following is for reference. Figures 1-6 This invention describes a TBM concrete rebound material collection and tunnel bottom cleaning device according to an embodiment of the present invention. The TBM concrete rebound material collection and tunnel bottom cleaning device can be installed on a tunnel boring machine (TBM). When the TBM is used to excavate tunnel 41, the TBM concrete rebound material collection and tunnel bottom cleaning device can collect impurities inside tunnel 41.

[0023] According to the first aspect of the present invention, a TBM concrete rebound material collection and tunnel bottom cleaning device is provided, such as Figures 1-6 As shown, the TBM concrete rebound material collection and tunnel bottom cleaning device may include: a rebound material collection unit 10 and a tunnel bottom cleaning unit 20. The rebound material collection unit 10 includes: a first conveying mechanism 11, a transfer mechanism 12, and a second conveying mechanism 13. The first conveying mechanism 11 is used to collect the rebound material 42 that falls from the inner wall of the tunnel 41. The first conveying mechanism 11 and the transfer mechanism 12 are adapted to be arranged along the length of the tunnel 41. The first conveying mechanism 11 is adapted to transport the collected rebound material 42 to the transfer mechanism 12, and the transfer mechanism 12 is adapted to transport the rebound material 42 to the second transfer mechanism 13. The conveying mechanism 13 extends along the length of the tunnel 41 to the outside of the tunnel 41. The tunnel bottom cleaning unit 20 includes a moving mechanism 21, a detection mechanism 22, and a gripping mechanism 23. The detection mechanism 22 and the gripping mechanism 23 are both fixed to the moving mechanism 21. The moving mechanism 21 is configured to drive the detection mechanism 22 and the gripping mechanism 23 to move synchronously along the length of the tunnel 41. The detection mechanism 22 is suitable for detecting objects inside the tunnel 41. The gripping mechanism 23 is configured to selectively adjust to a gripping state or a storage state according to the detection information of the detection mechanism 22.

[0024] It should be noted that in the current tunnel construction process, the generated debris, gravel and other impurities are generally cleaned up manually, which is inefficient and poses safety hazards. When spraying concrete into the inner wall of the tunnel to reinforce the tunnel structure, workers cannot clean up the rebound material in time. By the time the concrete has hardened, it is difficult to clean up the rebound material.

[0025] Based on this, this application proposes a TBM concrete rebound material collection and tunnel bottom cleaning device. TBM (Tunnel Boring Machine) is a tunnel boring machine. The TBM concrete rebound material collection and tunnel bottom cleaning device can be used to collect and clean the rebound material 42 that falls from the inner wall of the tunnel 41, as well as debris, gravel, and other impurities within the tunnel 41. The rebound material collection unit 10 can be used to collect the rebound material 42 that falls from the inner wall of the tunnel 41 when concrete is sprayed onto it. The tunnel bottom cleaning unit 20 can be used to clean the debris, gravel, and other impurities generated during the construction of the tunnel 41. The rebound material collection unit 10 may include a first conveying mechanism 11, a transfer mechanism 12, and a second conveying mechanism 13. The first conveying mechanism 11 can be used to collect the rebound material 42 that falls from the inner wall of the tunnel 41. The rebound material 42 that falls from the inner wall of the tunnel 41 can fall onto the first conveying mechanism 11. The first conveying mechanism 11 and the transfer mechanism 12 are adapted to be arranged along the length direction of the tunnel 41. The first conveying mechanism 11 can transport the collected rebound material 42 to the transfer mechanism 12 along the length direction of the tunnel 41. The transfer mechanism 12 is adapted to transport the rebound material 42 to the second conveying mechanism 13. The second conveying mechanism 13 can extend along the length of the tunnel 41 to the outside of the tunnel 41. That is, the second conveying mechanism 13 can transport the rebound material 42 to the outside of the tunnel 41, thereby realizing the effect of the rebound material collection unit 10 collecting the rebound material 42 and transporting the rebound material 42 to the outside of the tunnel 41. This is beneficial to the automated collection of the rebound material 42 that falls from the inner wall of the tunnel 41, reducing the probability of the rebound material 42 scattering and causing pollution to the tunnel 41, improving the efficiency of cleaning the rebound material 42, and reducing the difficulty of cleaning the rebound material 42.

[0026] The tunnel bottom cleaning unit 20 may include a moving mechanism 21, a detection mechanism 22, and a gripping mechanism 23. The moving mechanism 21 can move along the length of the tunnel 41. The detection mechanism 22 and the gripping mechanism 23 can be fixed to the moving mechanism 21 by means of bolts, welding, or other methods. The moving mechanism 21 can drive the detection mechanism 22 and the gripping mechanism 23 to move synchronously along the length of the tunnel 41. The detection mechanism 22 is used to detect objects inside the tunnel 41, that is, the detection mechanism 22 can detect the position of debris, gravel, and other impurities inside the tunnel 41. The detection mechanism 22 can also detect whether there are workers or mechanical equipment below the tunnel bottom cleaning unit 20. The gripping mechanism 23 can be configured to selectively adjust to a gripping state or a retracted state based on the detection information from the detection mechanism 22. When the detection mechanism 22 detects that there are no obstacles such as workers or machinery below the tunnel bottom cleaning unit 20, the gripping mechanism 23 can adjust to the gripping state. The detection mechanism 22 can detect the position of debris, gravel, and other impurities in the tunnel 41. The gripping mechanism 23 can grip the debris, gravel, and other impurities in the tunnel 41 based on the detection information from the detection mechanism 22, thereby achieving the effect of automatically cleaning debris, gravel, and other impurities in the tunnel 41 by the tunnel bottom cleaning unit 20. This helps to reduce the labor cost of tunnel bottom cleaning and improve the work efficiency of cleaning debris, gravel, and other impurities in the tunnel 41. When the detection mechanism 22 detects that there are workers or machinery or other objects below the gripping mechanism 23, the gripping mechanism 23 is always in the retracted state, which helps to reduce the probability of collision between the gripping mechanism 23 and workers or machinery or other objects and improves the reliability of the tunnel bottom cleaning unit 20.

[0027] In this embodiment, by setting up the rebound material collection unit 10 and the tunnel bottom cleaning unit 20, it is beneficial to achieve the effects of automatically collecting the rebound material 42 falling from the inner wall of the tunnel 41 and automatically cleaning the slag, gravel and other impurities in the tunnel 41. It is beneficial to reduce the probability of the rebound material 42 scattering and causing pollution to the tunnel 41, improve the work efficiency of cleaning the rebound material 42, reduce the difficulty of cleaning the rebound material 42, reduce the labor cost of cleaning the tunnel bottom, improve the work efficiency of cleaning the slag, gravel and other impurities in the tunnel 41, reduce the probability of the grabbing mechanism 23 colliding with personnel or mechanical equipment, improve the reliability of the tunnel bottom cleaning unit 20, and improve the reliability of the TBM concrete rebound material collection and tunnel bottom cleaning device.

[0028] In some embodiments of the present invention, such as Figure 2 and Figure 3 As shown, both the first transmission mechanism 11 and the second transmission mechanism 13 extend along the length of the tunnel 41, and the second transmission mechanism 13 is located above the first transmission mechanism 11.

[0029] Both the first conveying mechanism 11 and the second conveying mechanism 13 can extend along the length of the tunnel 41. The first conveying mechanism 11 can transport the collected rebound material 42 to the transfer mechanism 12 along the length of the tunnel 41. The first conveying mechanism 11 and the second conveying mechanism 13 can be arranged vertically spaced apart, with the second conveying mechanism 13 located above the first conveying mechanism 11. The transfer mechanism 12 can transport the rebound material 42 to the second conveying mechanism 13 vertically, and the second conveying mechanism 13 can transport the rebound material 42 to the outside of the tunnel 41 along the length of the tunnel 41. This improves the efficiency of the rebound material collection unit 10 in transporting the rebound material 42 to the outside of the tunnel 41. When the baffle 15 is as follows... Figure 1 When setting the direction, the vertical direction can be... Figure 1 The Z-direction of the material. Furthermore, by setting the second conveying mechanism 13 above the first conveying mechanism 11, it is beneficial to improve the structural compactness of the rebound material collection unit 10 and reduce the space occupied by the rebound material collection unit 10.

[0030] As an example, there can be two first conveying mechanisms 11. The two first conveying mechanisms 11 can be arranged along the width direction of the tunnel 41, and both first conveying mechanisms 11 can extend along the length direction of the tunnel 41. The two first conveying mechanisms 11 can be used to collect the rebound material 42 that falls from the side wall of the corresponding side tunnel 41. This helps to reduce the probability that the rebound material 42 falls to the bottom of the tunnel 41, further reduces the probability that the rebound material 42 will cause the tunnel 41 to be contaminated by scattering, further reduces the difficulty of cleaning up the rebound material 42, and improves the reliability of the rebound material collection unit 10.

[0031] As an example, the first conveying mechanism 11 can be configured as a conveyor belt mechanism. The first conveying mechanism 11 may include an annular first conveyor belt 111, two first rollers 112, and a first drive motor. The two first rollers 112 may be respectively located at both ends of the first conveyor belt 111 along its extension direction. The first conveyor belt 111 can be drivenly connected to the first rollers 112. The outer peripheral wall of the first rollers 112 can fit against the inner wall of the first conveyor belt 111. The first drive motor can drive the first rollers 112 to rotate, thereby achieving the effect of the first drive motor driving the first rollers 112 to rotate and thus moving the first conveyor belt 111. The first conveying mechanism 11 may also include multiple first idlers. The multiple first idlers can be evenly arranged along the extension direction of the first conveying mechanism 11 and can be located below the first conveyor belt 111, thereby supporting the first conveyor belt 111. This helps reduce the probability of the first conveyor belt 111 denting due to carrying the rebound material 42 and improves the reliability of the first conveying mechanism 11.

[0032] As an example, the second conveying mechanism 13 can be configured as a conveyor belt mechanism. The second conveying mechanism 13 may include an annular second conveyor belt 131, two second rollers 132, and a second drive motor. The two second rollers 132 may be respectively located at both ends of the second conveyor belt 131 along the extending direction of the second conveying mechanism 13. The second conveyor belt 131 can be driven to rotate with the second rollers 132. The outer peripheral wall of the second rollers 132 can fit against the inner wall of the second conveyor belt 131. The second drive motor can drive the second rollers 132 to rotate, thereby achieving the effect of the second drive motor driving the second rollers 132 to rotate and thus moving the second conveyor belt 131. The second conveying mechanism 13 may also include multiple second idlers 133. The multiple second idlers 133 can be evenly arranged along the extending direction of the second conveying mechanism 13 and can be located below the second conveyor belt 131, thereby supporting the second conveyor belt 131. This helps reduce the probability of the second conveyor belt 131 denting due to carrying the rebound material 42 and improves the reliability of the second conveying mechanism 13.

[0033] As an example, the inner wall of tunnel 41 may include side walls and top walls of tunnel 41. Tunnel 41 may also include a guide portion 31, which can avoid the second conveying mechanism 13 and may be located above the second conveying mechanism 13. The guide portion 31 may be constructed as annular, and the outer peripheral wall of the guide portion 31 may be arranged radially opposite to and spaced apart from the inner wall of tunnel 41. The rebound material 42 falling from the side wall of tunnel 41 can fall to the first conveying mechanism 11 on the corresponding side. The rebound material 42 falling from the top wall of tunnel 41 can fall to the outer peripheral wall of guide part 31. The rebound material 42 falling from the top wall of tunnel 41 can flow along the outer peripheral wall of guide part 31 under the action of gravity. The rebound material 42 on the outer peripheral wall of guide part 31 can flow to the first conveying mechanism 11. This is conducive to further realizing the effect of the first conveying mechanism 11 in collecting the rebound material 42 falling from the inner wall of tunnel 41, which is conducive to further reducing the probability of the rebound material 42 falling to the bottom of tunnel 41, and further reducing the probability of the rebound material 42 scattering and causing contamination of tunnel 41.

[0034] In some embodiments of the present invention, such as Figure 1 and Figure 2 As shown, the rebound material collection unit 10 may further include: a flow guiding mechanism 14, which is located on one side of the first conveying mechanism 11 and connected to the first conveying mechanism 11. The flow guiding mechanism 14 is adapted to contact the side wall of the tunnel 41 and is used to guide the rebound material 42 falling from the inner wall of the tunnel 41 to the first conveying mechanism 11.

[0035] The flow guiding mechanism 14 can be located on one side of the first conveying mechanism 11, near the sidewall of the tunnel 41. The flow guiding mechanism 14 can be connected to the first conveying mechanism 11 by means of bonding, snap-fitting, or other methods. The flow guiding mechanism 14 can contact the sidewall of the tunnel 41, which helps reduce the probability of a gap between the flow guiding mechanism 14 and the sidewall of the tunnel 41. This reduces the probability of the rebound material 42 falling from the sidewall of the tunnel 41 falling through the gap between the flow guiding mechanism 14 and the sidewall of the tunnel 41 to the bottom of the tunnel 41, further reducing the probability of contamination of the tunnel 41 by the rebound material 42. The flow guiding mechanism 14 can guide the rebound material 42 falling from the inner wall of the tunnel 41. The rebound material 42 falling from the inner wall of the tunnel 41 can fall onto the flow guiding mechanism 14, which can guide the rebound material 42 falling from the inner wall of the tunnel 41 to the first conveying mechanism 11. This is beneficial to further realize the effect of the first conveying mechanism 11 in collecting the rebound material 42 falling from the inner wall of the tunnel 41, further reducing the probability of the rebound material 42 falling to the bottom of the tunnel 41, further reducing the probability of the rebound material 42 scattering and causing pollution of the tunnel 41, improving the automation level of the rebound material collection unit 10 in collecting the rebound material 42, and further improving the reliability of the rebound material collection unit 10.

[0036] In some embodiments of the present invention, such as Figure 1 and Figure 2 As shown, the flow guiding mechanism 14 may include: a first flow guiding plate 141, which is constructed as an arc shape.

[0037] One side of the first guide plate 141 can contact the side wall of the tunnel 41, and the other side of the first guide plate 141 can be connected to the first conveying mechanism 11. The first guide plate 141 can be constructed as an arc shape. The first guide plate 141 can extend along the side wall of the tunnel 41 to the first conveying mechanism 11. The first guide plate 141 can protrude towards the bottom of the tunnel 41, which helps to adapt the structure of the first guide plate 141 to the shape of the inner wall of the tunnel 41. This helps to improve the guiding effect of the first guide plate 141 on the rebound material 42 falling from the inner wall of the tunnel 41, and helps to reduce the probability of the rebound material 42 falling from the inner wall of the tunnel 41 accumulating or getting stuck on the first guide plate 141. Moreover, the arc shape of the first guide plate 141 can buffer the rebound material 42 falling from the inner wall of the tunnel 41, which helps to disperse the impact force of the rebound material 42 falling from the inner wall of the tunnel 41 onto the first guide plate 141, and helps to extend the service life of the first guide plate 141.

[0038] As an example, the flow guiding mechanism 14 may also include a first support rod 142, which may be located below the first flow guiding plate 141. The first support rod 142 can be used to support the first flow guiding plate 141, which helps to improve the stability and reliability of the first flow guiding plate 141 during operation.

[0039] In some embodiments of the present invention, such as Figure 1 As shown, the rebound material collection unit 10 may further include: a baffle plate 15, which is located on the other side of the first conveying mechanism 11 away from the flow guiding mechanism 14, and the baffle plate 15 extends in the vertical direction.

[0040] The baffle 15 can be located on the side of the first conveying mechanism 11 opposite to the flow guiding mechanism 14. The baffle 15 can extend vertically and can be connected to the first conveying mechanism 11. The baffle 15 can prevent the rebound material 42 on the first conveying mechanism 11 from overflowing from the other side of the first conveying mechanism 11, which helps to further reduce the probability of the rebound material 42 falling to the bottom of the tunnel 41 and further reduce the probability of the rebound material 42 scattering and causing contamination of the tunnel 41. In addition, the baffle 15 can also block the wind, which helps to reduce the probability of the rebound material 42 solidifying due to wind, which helps to reduce the rate of solidification and hardening of the rebound material 42, which helps to further reduce the difficulty of cleaning the rebound material 42 and further improve the work efficiency of cleaning the rebound material 42.

[0041] In some embodiments of the present invention, such as Figure 1 As shown, the shield 15 includes a first sub-plate 151 and a second sub-plate 152 connected together. The first sub-plate 151 is located below the second sub-plate 152 and extends in a vertical direction. From the lower end to the upper end of the second sub-plate 152, the second sub-plate 152 extends obliquely to one side of the flow guide mechanism 14.

[0042] The first sub-plate 151 and the second sub-plate 152 can be connected to each other, bonded together, or integrally formed. The first sub-plate 151 can be located below the second sub-plate 152 and extend vertically. The first sub-plate 151 can be connected to the first conveying mechanism 11 and can prevent the spring material 42 on the first conveying mechanism 11 from overflowing from the other side of the first conveying mechanism 11. From the lower end to the upper end of the second sub-plate 152, the second sub-plate 152 can extend obliquely to one side of the guide mechanism 14. Vertically, the second sub-plate 152 can be opposite to and spaced apart from the first conveying mechanism 11. The second sub-plate 152 can act as a windbreak for the spring material 42 on the first conveying mechanism 11, thereby reducing the probability of the spring material 42 solidifying due to wind. As an example, the second sub-plate 152 can be constructed as an arc-shaped structure.

[0043] As an example, the vertical projection of the second sub-plate 152 falls within the vertical projection range of the first conveying mechanism 11. Along the width direction of the first conveying mechanism 11, the width dimension of the second sub-plate 152 is D1, and the width dimension of the first conveying mechanism 11 is D2, satisfying the relationship: 0.5 ≤ D1 / D2 ≤ 0.8. Exemplarily, the ratio of the width dimension of the second sub-plate 152 to the width dimension of the first conveying mechanism 11 can be 0.5, 0.57, 0.64, 0.72, 0.8, etc. The ratio of the width dimension of the second sub-plate 152 to the width dimension of the first conveying mechanism 11 can be within the range of 0.5 to 0.8. Any value, including endpoint values, is an optional ratio of the width dimension of the second sub-plate 152 to the width dimension of the first conveying mechanism 11 in this invention.

[0044] If the ratio of the width of the second sub-plate 152 to the width of the first conveying mechanism 11 is less than 0.5, it will affect the windproofing effect of the second sub-plate 152 on the rebound material 42 on the first conveying mechanism 11, making it easier for the rebound material 42 on the first conveying mechanism 11 to solidify and harden quickly, increasing the difficulty of cleaning the rebound material 42 and affecting the working efficiency of cleaning the rebound material 42. If the ratio of the width of the second sub-plate 152 to the width of the first conveying mechanism 11 is greater than 0.8, the width of the second sub-plate 152 is too large, making it easy for the rebound material 42 falling from the inner wall of the tunnel 41 to fall onto the second sub-plate 152, affecting the effectiveness of the first conveying mechanism 11 in collecting the rebound material 42 falling from the inner wall of the tunnel 41. Therefore, the ratio of the width of the second sub-plate 152 to the width of the first conveying mechanism 11 is in the range of 0.5 to 0.8. This ensures that the second sub-plate 152 does not affect the windproof effect of the rebound material 42 on the first conveying mechanism 11, while also allowing the rebound material 42 falling from the inner wall of the tunnel 41 to fall smoothly onto the first conveying mechanism 11, which is beneficial to further improving the reliability of the rebound material collection unit 10.

[0045] In some embodiments of the present invention, such as Figure 4 As shown, the rebound material collection unit 10 may further include a spraying mechanism 16, which is used to spray concrete retarder and water onto the rebound material 42 on the first conveying mechanism 11.

[0046] The spraying mechanism 16 can be used to spray concrete retarder and water onto the rebound material 42 on the first conveying mechanism 11. The spraying mechanism 16 can be located on the side of the second sub-plate 152 facing the first conveying mechanism 11, that is, on the lower surface of the second sub-plate 152. The spraying mechanism 16 can be located above the rebound material 42 on the first conveying mechanism 11, which is beneficial to improving the working efficiency of the spraying mechanism 16 in spraying concrete retarder and water onto the rebound material 42 on the first conveying mechanism 11. The spraying mechanism 16 can spray concrete retarder onto the rebound material 42 on the first conveying mechanism 11, which is beneficial to further reduce the setting and hardening rate of the rebound material 42, further reduce the difficulty of cleaning the rebound material 42, and further improve the working efficiency of cleaning the rebound material 42. The spraying mechanism 16 can spray water onto the rebound material 42 on the first conveying mechanism 11, which helps to further reduce the rate of solidification and hardening of the rebound material 42, further reduce the difficulty of cleaning the rebound material 42, and further improve the work efficiency of cleaning the rebound material 42.

[0047] As an example, the spraying mechanism 16 may include a first pipe 161 and a second pipe 162 arranged adjacent to each other. Both the first pipe 161 and the second pipe 162 can extend along the length direction of the tunnel 41, and the first pipe 161 and the second pipe 162 can be arranged along the width direction of the tunnel 41. The first pipe 161 and the second pipe 162 can be connected. Each of the first pipe 161 and the second pipe 162 may be provided with a nozzle 163 on the side facing the first conveying mechanism 11. One of the first pipe 161 and the second pipe 162 can be used to spray concrete retarder, and the other of the first pipe 161 and the second pipe 162 can be used to spray water.

[0048] In some embodiments of the present invention, such as Figure 2 , Figure 3 and Figure 5 As shown, the transfer mechanism 12 may include: a first guide rail 121 and a hopper 122. The first guide rail 121 extends vertically. The lower end of the first guide rail 121 is lower than the height of the first conveying mechanism 11, and the upper end of the first guide rail 121 is higher than the height of the second conveying mechanism 13. The hopper 122 is movably disposed on the first guide rail 121 along the extension direction of the first guide rail 121. The first conveying mechanism 11 is adapted to transport the collected rebound material 42 to the hopper 122, and the hopper 122 is used to transport the rebound material 42 to the second conveying mechanism 13.

[0049] The first guide rail 121 can extend vertically, and the hopper 122 is movably disposed on the first guide rail 121 along the extension direction of the first guide rail 121. The hopper 122 can be moved to the lower end and the upper end of the first guide rail 121. There can be two first guide rails 121, which can be disposed on both sides of the hopper 122 along the width direction of the hopper 122, which helps to improve the reliability of the hopper 122 when moving on the first guide rail 121. In the vertical direction, the lower end of the first guide rail 121 can be lower than the first conveying mechanism 11. When the hopper 122 is located at the lower end of the first guide rail 121, the hopper 122 can be used to receive the rebound material 42 on the first conveying mechanism 11. When the spring material 42 on the first conveyor 11 moves to the end of the first conveyor 11 near the hopper 122, the hopper 122 is located at the lower end of the first guide rail 121. The spring material 42 on the first conveyor 11 can fall into the hopper 122, and the hopper 122 can move the spring material 42 in the hopper 122 to the upper end of the first guide rail 121. In the vertical direction, the upper end of the first guide rail 121 can be higher than the second conveyor 13. When the hopper 122 is located at the upper end of the first guide rail 121, the hopper 122 can transport the spring material 42 to the second conveyor 13, thereby achieving the effect of the transfer mechanism 12 transferring the spring material 42 on the first conveyor 11 to the second conveyor 13.

[0050] As an example, a first rack may be provided on the first guide rail 121, and the first rack may extend along the extending direction of the first guide rail 121. A first drive unit may be provided on the hopper 122, which may drive the hopper 122 to rise or fall along the first guide rail 121. The first drive unit may include a third drive motor and a reduction gear. The reduction gear may be connected to the first motor shaft of the third drive motor, and the reduction gear may mesh with the first rack. When the third drive motor drives the first motor shaft to rotate, the first motor shaft may drive the reduction gear to rotate synchronously. The reduction gear may move relative to the first rack along the extending direction of the first guide rail 121, thereby achieving the effect of raising or lowering the hopper 122.

[0051] As an example, the hopper 122 may be connected to a first slider. The first slider may be movably disposed on the first guide rail 121 along the extension direction of the first guide rail 121. When the first drive unit drives the hopper 122 to rise or fall along the extension direction of the first guide rail 121, the first slider may move within the first guide rail 121, which helps to reduce the probability of the hopper 122 falling off the first guide rail 121 and improves the reliability of the hopper 122 when it moves.

[0052] In some embodiments of the present invention, the hopper 122 is configured to pour the rebound material 42 to the second conveying mechanism 13 when it moves to the upper end of the first guide rail 121.

[0053] The hopper 122 is configured to pour the rebound material 42 to the second conveying mechanism 13 when it moves to the upper end of the first guide rail 121. When the hopper 122 moves to the upper end of the first guide rail 121, the hopper 122 can rotate relative to the second conveying mechanism 13, thereby achieving the effect of the hopper 122 pouring the rebound material 42 to the second conveying mechanism 13.

[0054] As an example, the hopper 122 may be equipped with a second drive unit, which may be located on one side of the hopper 122 along its width direction. The second drive unit may be connected to a first drive rod, which may pass through the hopper 122 along its width direction and be fixedly connected to the hopper 122. The second drive unit may include a fourth drive motor, and the second motor shaft of the fourth drive motor may be fixedly connected to the first drive rod through a coupling, sleeve, or the like. When the fourth drive motor drives the second motor shaft to rotate, the second motor shaft may drive the first drive rod to rotate synchronously, and the first drive rod may drive the hopper 122 to rotate synchronously. This achieves the effect of allowing the hopper 122 to rotate relative to the second conveying mechanism 13, which is beneficial for the hopper 122 to pour the rebound material 42 into the second conveying mechanism 13.

[0055] As an example, the first guide rail 121 may include a first arc-shaped segment 1211, a first straight segment 1212, and a second arc-shaped segment 1213. The first arc-shaped segment 1211, the first straight segment 1212, and the second arc-shaped segment 1213 can be arranged vertically and connected sequentially. The first arc-shaped segment 1211 may be located below the first straight segment 1212, and the second arc-shaped segment 1213 may be located above the first straight segment 1212. From its upper end to its lower end, the first arc-shaped segment 1211 may extend obliquely toward the first conveying mechanism 11. By providing the first guide rail 121 with the first arc-shaped segment 1211, it is advantageous to position the lower end of the first guide rail 121 below the first conveying mechanism 11, facilitating the drop of the rebound material 42 from the first conveying mechanism 11 into the hopper 122. From its lower end to its upper end, the second arc-shaped segment 1213 may extend obliquely toward the second conveying mechanism 13. By setting the first guide rail 121 to have a second arc-shaped segment 1213, it is advantageous to position the upper end of the second guide rail 211 above the second conveying mechanism 13, which facilitates the hopper 122 to pour the rebound material 42 in the hopper 122 to the second conveying mechanism 13.

[0056] In some embodiments of the present invention, such as Figure 2 As shown, the transfer mechanism 12 may further include a guide section 123, which is located at the upper end of the first guide rail 121. When the hopper 122 pours the rebound material 42 into the second transfer mechanism 13, the guide section 123 is configured to guide the rebound material 42 to the second transfer mechanism 13.

[0057] The guide section 123 can be located at the upper end of the first guide rail 121, and can be fixedly connected to the upper end of the first guide rail 121 by means of bonding, welding, etc. When the hopper 122 pours the rebound material 42 into the second conveying mechanism 13, the guide section 123 can be configured to guide the rebound material 42 to the second conveying mechanism 13. This is beneficial for the rebound material 42 in the hopper 122 to flow along the guide section 123 to the second conveying mechanism 13, which further reduces the probability that the rebound material 42 will fall to the bottom of the tunnel 41, and further reduces the probability that the rebound material 42 will scatter and cause pollution to the tunnel 41. As an example, the flow guide 123 can be configured as a flow guide plate, extending from one end of the flow guide 123 connected to the first guide rail 121 to the other end of the flow guide 123. The flow guide plate can extend obliquely toward the second conveying mechanism 13. The height of the end of the flow guide 123 connected to the first guide rail 121 can be higher than the other end of the flow guide 123. The flow guide plate can be configured as a flat plate structure.

[0058] As an example, when the hopper 122 pours the rebound material 42 into the second conveying mechanism 13, the guide section 123 can vibrate, which helps to reduce the probability of the rebound material 42 adhering to the guide section 123 and helps to ensure that all the rebound material 42 in the hopper 122 falls into the second conveying mechanism 13.

[0059] In some embodiments of the present invention, the rebound material collection unit 10 may further include: a first controller, an infrared sensor, a humidity sensor, and a gravity sensor. The first controller is communicatively connected to the infrared sensor, the humidity sensor, and the gravity sensor. The infrared sensor is configured to detect whether there is rebound material 42 on the first conveying mechanism 11. The humidity sensor is configured to detect the humidity of the rebound material 42 on the first conveying mechanism 11. The gravity sensor is configured to detect the weight of the rebound material 42 transported by the transfer mechanism 12. The first controller controls the rebound material collection unit 10 to work based on the detection information of the infrared sensor, the detection information of the humidity sensor, and the detection information of the gravity sensor.

[0060] The first controller can communicate with an infrared sensor, a humidity sensor, and a gravity sensor. The infrared sensor can be located on the side of the second sub-board 152 facing the first conveying mechanism 11. The infrared sensor can be configured to detect whether there is rebound material 42 on the first conveying mechanism 11. When the infrared sensor detects rebound material 42 on the first conveying mechanism 11, the first controller can drive the first conveying mechanism 11 to work, so that the first conveying mechanism 11 transports the rebound material 42 on the first conveying mechanism 11 to the transfer mechanism 12. At the same time, when the first conveying mechanism 11 starts working, the first controller can control the spraying mechanism 16 to spray concrete retarder onto the rebound material 42 on the first conveying mechanism 11. The humidity sensor can be located on the side of the second sub-board 152 facing the first conveying mechanism 11. The humidity sensor can be configured to detect the humidity of the rebound material 42 on the first conveying mechanism 11. When the humidity sensor detects that the humidity of the rebound material 42 on the first conveying mechanism 11 is lower than the standard value, the first controller can control the spraying mechanism 16 to spray water onto the rebound material 42 on the first conveying mechanism 11.

[0061] A gravity sensor can be installed on the hopper 122. The gravity sensor can be configured to detect the weight of the rebound material 42 transported by the transfer mechanism 12. When the gravity sensor detects that the weight of the rebound material 42 in the hopper 122 equals a standard value, the first controller controls the first conveying mechanism 11 to stop working, and simultaneously the spraying mechanism 16 stops working. The first controller controls the first drive unit to move the hopper 122 along the extension direction of the first guide rail 121 to the upper end of the first guide rail 121. The first controller can also drive the second drive unit to rotate the hopper 122 so that the hopper 122 pours the rebound material 42 into the second conveying mechanism 13. By setting the first controller, the automation level of the rebound material collection unit is further improved, and the reliability of the rebound material collection unit 10 is further improved.

[0062] In some embodiments of the present invention, such as Figure 6 As shown, the moving mechanism 21 may include a second guide rail 211 and a moving part 212. The second guide rail 211 is adapted to extend along the length direction of the tunnel 41, and the moving part 212 is movably disposed on the second guide rail 211 along the length direction of the second guide rail 211. The detection mechanism 22 and the gripping mechanism 23 are both fixedly disposed on the moving part 212.

[0063] The second guide rail 211 can extend along the length of the tunnel 41. A movable part 212 can be disposed on the second guide rail 211 and can move along the length of the second guide rail 211. As an example, in the vertical direction, the side of the movable part 212 facing the second guide rail 211 can have a second slider. At least one second slider can be provided, and the second slider can be integrally formed with the movable part 212. The second slider and the movable part 212 can be connected by bolts. The second slider can be assembled with the second guide rail 211 and can move along the length of the second guide rail 211, thereby achieving the effect that the movable part 212 is movably disposed on the second guide rail 211 along the length of the second guide rail 211.

[0064] Both the detection mechanism 22 and the gripping mechanism 23 can be fixedly mounted on the moving part 212. Both the detection mechanism 22 and the gripping mechanism 23 can be fixedly connected to the moving part 212 by means of bolts, snap-fit, etc. The moving part 212 can drive the detection mechanism 22 and the gripping mechanism 23 to move synchronously along the length direction of the second guide rail 211, thereby achieving the effect of moving the detection mechanism 22 and the gripping mechanism 23 along the length direction of the second guide rail 211. This is beneficial to increasing the detection range of the detection mechanism 22 and the gripping range of the gripping mechanism 23.

[0065] As an example, the tunnel bottom cleaning unit 20 may also include a second controller, which may be communicatively connected to the moving part 212, the detection mechanism 22 and the gripping mechanism 23. The second controller may control the moving part 212 to move according to the detection information of the detection mechanism 22, and the second controller may control the gripping mechanism 23 to selectively adjust to the gripping state or the storage state according to the detection information of the detection mechanism 22.

[0066] As an example, the detection mechanism 22 can be configured as a laser scanner, which can be used to scan objects inside the tunnel 41. When the laser scanner detects that there are personnel or mechanical equipment below the gripping mechanism 23, the second controller can control the gripping mechanism 23 to always be in the retracted state. When the detection mechanism 22 detects that there are no obstacles such as personnel or mechanical equipment below the tunnel bottom cleaning unit 20 and that there are impurities such as slag and gravel inside the tunnel 41, the second controller can control the gripping mechanism 23 to adjust to the gripping state, and the gripping mechanism 23 can grip the slag and gravel inside the tunnel 41. When the detection mechanism 22 detects that there are impurities such as slag and gravel inside the tunnel 41 and the gripping mechanism 23 is not above the corresponding impurities, the second controller can control the moving part 212 to move above the impurities.

[0067] As an example, the tunnel bottom cleaning unit 20 may also include a locking structure, which can be assembled with the second guide rail 211 and the moving part 212 respectively, so as to achieve the effect of the moving part 212 being relatively stationary with respect to the second guide rail 211. This is beneficial to achieving the effect of the moving part 212 being relatively stationary with respect to the second guide rail 211 when the gripping mechanism 23 is in the gripping state, and to improving the stability and reliability of the gripping mechanism 23 when gripping impurities in the tunnel 41.

[0068] As an example, the locking structure can be constructed as a locking pin, the second guide rail 211 can have a first mating hole, and the moving part 212 can have a second mating hole. When the locking pin is simultaneously inserted into the first mating hole and the second mating hole, the moving part 212 is relatively stationary with respect to the second guide rail 211, thereby achieving the effect of fixing and locking the moving part 212.

[0069] In some embodiments of the present invention, such as Figure 6 As shown, the gripping mechanism 23 may include a connecting arm 231 and a gripper 232. One end of the connecting arm 231 is connected to the moving part 212, and the other end of the connecting arm 231 is connected to the gripper 232. The connecting arm 231 includes a plurality of sub-connecting arms 2311, which are connected sequentially along the length of the connecting arm 231. Any two adjacent sub-connecting arms 2311 are rotatably connected so that the gripping mechanism 23 can be selectively adjusted to a gripping state or a storage state.

[0070] One end of the connecting arm 231 can be connected to the moving part 212, which can drive the connecting arm 231 to move synchronously. The other end of the connecting arm 231 can be connected to the gripper 232, which can be used to grab debris such as slag and gravel inside the tunnel 41. The connecting arm 231 may include multiple sub-connecting arms 2311, which can be connected sequentially along the length of the connecting arm 231. Any two adjacent sub-connecting arms 2311 can be rotatably connected and can rotate relative to each other, thereby allowing the gripping mechanism 23 to selectively adjust to a gripping state or a retracted state. When the gripping mechanism 23 is adjusted to the gripping state, the gripper 232 can move to the bottom of the tunnel 41. When the gripping mechanism 23 is adjusted to the retracted state, the gripper 232 can avoid objects inside the tunnel 41, which helps to further improve the reliability of the tunnel bottom cleaning unit 20.

[0071] As an example, the connecting arm 231 may also include multiple driving structures 2312, which can be configured one-to-one with multiple sub-connecting arms 2311. Each sub-connecting arm 2311 has a corresponding driving structure 2312. Each driving structure 2312 can be located at one end of the corresponding sub-connecting arm 2311. Each driving structure 2312 can drive the corresponding sub-connecting arm 2311 to rotate, thereby achieving the effect of relative rotation of multiple sub-connecting arms 2311. This is beneficial for further realizing the effect of selectively adjusting the gripping mechanism 23 to the gripping state or the storage state.

[0072] According to a second aspect of the present invention, a tunnel boring machine includes the TBM concrete rebound material collection and tunnel bottom cleaning device described in the above embodiments.

[0073] According to the tunnel boring machine of the present application embodiment, using the TBM concrete rebound material collection and tunnel bottom cleaning device in the above embodiment is beneficial to improving the efficiency of collecting rebound material 42 and impurities such as slag and gravel in the tunnel 41, which is beneficial to improving the construction efficiency of the tunnel boring machine and reducing the environmental impact of rebound material 42 and impurities in the tunnel 41.

[0074] As an example, the tunnel boring machine may also include: a tunneling device, a rebound material collection unit 10 and a tunnel bottom cleaning unit 20 which can be arranged along the length of the tunnel 41. The tunnel bottom cleaning unit 20 can be located between the rebound material collection unit 10 and the tunneling device. When the tunneling device is used to excavate the tunnel 41, the tunnel bottom cleaning unit 20 can be used to clean up the debris, gravel and other impurities that fall at the bottom of the tunnel 41 during the excavation of the tunnel 41.

[0075] As an example, the tunnel boring machine may also include multiple buckets, which can be arranged along the length of the tunnel boring machine. The rebound material collection unit 10 and the tunnel bottom cleaning unit 20 can be located in different buckets. The rebound material collection unit 10 and the tunnel bottom cleaning unit 20 can be fixed in the corresponding buckets, thereby achieving the effect of synchronous movement of the rebound material collection unit 10 and the tunnel bottom cleaning unit 20 with the tunneling device.

[0076] As an example, the tunneling machine may also include a concrete spraying device 30, which may be located in the same bucket as the rebound material collection unit 10, and may be used in conjunction with the rebound material collection unit 10. The concrete spraying device 30 may include a first support 32, a guide 31, and a spraying mechanism 33. The first support 32 may be fixedly connected to the corresponding bucket and may be used to support the guide 31. The guide 31 may be constructed as a ring, and its outer peripheral wall may be arranged radially opposite to and spaced apart from the inner wall of the tunnel 41. The spraying mechanism 33 is movably disposed on the guide 31 along the extension direction of the guide 31. The spraying mechanism 33 may move along the extension direction of the guide 31 and spray concrete onto the inner wall of the tunnel 41. The concrete that does not adhere to the inner wall of the tunnel 41 and falls off constitutes rebound material 42. The rebound material 42 falls onto the first conveying mechanism 11 and is transported to the outside of the tunnel 41 by the transfer mechanism 12 and the second conveying mechanism 13.

[0077] Other components and operations of the TBM concrete rebound material collection and tunnel bottom cleaning device according to embodiments of the present invention are known to those skilled in the art and will not be described in detail here.
