Abstract
Description
Technical Field
[0001] This application relates to the field of tunnel construction technology, and in particular to a storage bin assembly and a tunnel boring device. Background Technology
[0002] A TBM (Tunnel Boring Machine) is a type of engineering equipment used for full-face tunnel construction. The conveyor belt is a crucial component of the TBM, playing a vital role in transporting excavated material. Its performance and efficiency significantly impact the tunnel construction progress. The TBM is equipped with a belt storage bin. During tunneling, the belt continuously releases from the bin, gradually discharging as the conveyor belt extends.
[0003] The belt storage capacity of the belt storage bin is a key factor limiting the tunneling efficiency of TBMs. Insufficient storage capacity leads to belt replacements, resulting in more belt joints, which are often weak and can even cause belt breakage, halting construction. Furthermore, for TBMs with multiple horizontal turns, a conveyor belt overlap method is typically used for muck removal. This overlap process requires modifications, which can lead to equipment downtime, significantly extending the construction period.
[0004] Therefore, how to improve the current weak storage capacity of existing belt conveyors and how to shorten the equipment downtime during the belt conveyor connection and transformation process have become urgent problems to be solved. Summary of the Invention
[0005] This application provides a tape storage bin assembly and a tunnel boring machine. By including a head tape storage bin and a tail tape storage bin, compared to the existing model that only includes a head tape storage bin, the storage length of the tape storage bin can be significantly increased, and the number of belt conveyor joints in the tape storage bin can be reduced, thereby reducing the construction or production time lost due to filling the tape storage bin. By setting a tail tape storage bin, this application can continuously release tape from the belt conveyor during the belt conveyor overlap modification process, ensuring that tunneling and belt conveyor overlap are carried out synchronously without downtime. This shortens the equipment downtime during belt conveyor overlap modification, minimizes the construction period, improves construction efficiency, saves construction costs caused by downtime, and avoids the problems of weak tape storage capacity of the tape storage bin and relatively long equipment downtime during belt conveyor overlap modification in related technologies.
[0006] To achieve the above objectives, a first aspect of this application provides a tape storage bin assembly disposed in a tunnel boring machine. The tape storage bin assembly includes a tape storage bin and at least two belt conveyors disposed on the tape storage bin. The tape storage bin includes a head tape storage bin and a tail tape storage bin disposed along the length direction of the tunnel boring machine. The head tape storage bin is located near the tunnel boring end of the tunnel boring machine, and the tail tape storage bin is located away from the tunnel boring end. The belt conveyors include a first belt conveyor and a second belt conveyor, with the first belt conveyor disposed in front of the second belt conveyor along the tunneling direction. When the tunnel boring machine is tunneling along a first horizontal section, the head tape storage bin is connected to the side of the first belt conveyor near the tunnel boring end, and the tail tape storage bin is connected to the side of the first belt conveyor away from the tunnel boring end. The head tape storage bin is positioned relative to the tunnel boring end. The first conveyor belt releases belt, and the tail belt storage bin cooperates with the first conveyor belt to release belt. The tunnel boring device excavates via the first conveyor belt. When the tunnel boring device completes the excavation of the first horizontal section and turns into the second horizontal section, the head belt storage bin is removed from the first conveyor belt. The head belt storage bin stops releasing belt to the first conveyor belt, while the tail belt storage bin continues releasing belt to the first conveyor belt. The second conveyor belt is connected between the tail belt storage bin and the first conveyor belt. The first and second conveyor belts are fixedly connected. The removed head belt storage bin is moved to the end of the second conveyor belt near the first conveyor belt. The head belt storage bin begins releasing belt to the second conveyor belt, and the tail belt storage bin cooperates with the second conveyor belt to release belt. The tunnel boring device excavates via the second conveyor belt.
[0007] In one possible implementation, the conveyor belts include multiple belts, each corresponding to the excavation of one horizontal section, and the multiple belt belts are arranged sequentially along the excavation direction. When the tunnel boring machine excavates multiple horizontal sections sequentially, the next belt belt is connected between the tail belt storage bin and the previous belt belt, and is fixedly connected to the previous belt belt. After the head belt storage bin is removed from the previous belt belt, the tail belt storage bin continues to release belt to the previous belt belt. The head belt storage bin is then moved to the end of the next belt belt near the side of the previous belt belt. The head belt storage bin releases belt to the next belt belt, and the tail belt storage bin cooperates in releasing belt to the next belt belt. The tunnel boring machine excavates via the next belt belt.
[0008] In one possible implementation, an interlocking device is provided between any two adjacent belt conveyors, and when the tunnel boring machine suspends tunneling, the two adjacent belt conveyors are interlocked through the interlocking device.
[0009] In one possible implementation, a muck transport device is also included, which is disposed between two adjacent belt conveyors; the muck transport device is used to transport the muck on the belt conveyors to the outside during the tunneling process.
[0010] In one possible implementation, the slag transport component includes a receiving end and a discharging end connected together; the receiving end is located at the end of the preceding belt conveyor near the side of the following belt conveyor, and the discharging end is located at the end of the following belt conveyor near the side of the preceding belt conveyor; the discharging end and the receiving end are used to transport the slag on the belt conveyor sequentially to the outside.
[0011] In one possible implementation, an end discharge device is also included, which is disposed on the side of the first belt conveyor away from the slag transporter; the end discharge device is used to receive slag transported via the slag transporter.
[0012] In one possible implementation, a drive unit is further included, which is disposed on the head belt storage bin and / or the tail belt storage bin; the drive unit is electrically connected to the belt conveyor and is used to drive the belt conveyor to move.
[0013] In one possible implementation, the bottom of the belt conveyor is provided with a plurality of rollers, and the belt conveyor moves via the rollers.
[0014] A second aspect of the embodiments of this application also provides a tunnel boring machine for use in a tunnel, the tunnel boring machine including a tunnel boring machine body and a tape storage bin assembly, the tape storage bin assembly being disposed in the tunnel boring machine body.
[0015] In one possible implementation, the tunneling device body is provided with a control component, which is electrically connected to the tape storage bin of the tape storage bin assembly. The control component is used to control the start or stop tape release of the tape storage bin.
[0016] The tape storage bin assembly and tunnel boring device provided in this application include a tape storage bin and at least two belt conveyors mounted on the tape storage bin. The tape storage bin includes a head tape storage bin and a tail tape storage bin. Compared to the existing configuration that only includes a head tape storage bin, this significantly increases the storage length of the tape storage bin and reduces the number of belt joints between belt conveyors within the storage bin, thereby reducing construction or production time lost due to filling the tape storage bin. By equipping the tail tape storage bin, the belt can be continuously released during belt conveyor connection and modification, ensuring that tunneling and belt conveyor connection are carried out synchronously without downtime. This shortens equipment downtime during belt conveyor connection and modification, minimizes construction period, improves construction efficiency, and saves construction costs incurred due to downtime. It avoids the problems of weak tape storage capacity of the tape storage bin and relatively long equipment downtime during belt conveyor connection and modification in related technologies.

[0030] With the development of the national economy and the acceleration of tunnel construction, the shield tunneling method has been widely used due to its economic efficiency. The shield tunneling method is a fully mechanized construction method in the cut-and-cover method. It involves advancing the shield machine underground, using the shield shell and segments to support the surrounding rock and prevent collapse into the tunnel. Simultaneously, cutting devices excavate the soil in front of the excavation face, transporting the excavated soil out of the tunnel using haulage machinery. Jacks then apply pressure from the rear to propel the tunnel forward, and precast concrete segments are assembled to form the tunnel structure.
[0031] Open-face TBMs (Tunnel Boring Machines) and slurry shield tunneling machines are two common tunneling devices. Open-face TBMs use belt conveyors for muck removal, offering high construction efficiency and the ability to handle long distances in hard rock conditions. However, they face difficulties in water-rich or sandy / muddy geology. Slurry shield tunneling machines, on the other hand, isolate the main body of the tunnel from the ground, effectively preventing water and soil pressure. They also use pumps to remove muck, making them better suited for water-rich and high-water-pressure strata. However, their construction efficiency is lower, and they are more expensive for continuous long-distance tunneling.
[0032] Taking an open-face TBM as an example, a TBM is an engineering equipment used for full-face tunnel construction. The belt conveyor is an important component of the TBM, playing a role in transporting excavated soil. Its performance and efficiency greatly affect the tunnel construction progress. The TBM is equipped with a belt storage bin. During the TBM's tunneling process, the belt storage bin continuously releases belt. The conveyor belt in the storage bin is gradually released as the belt conveyor extends.
[0033] Therefore, the belt storage capacity of the belt storage bin becomes a key factor limiting the tunneling efficiency of TBMs. Insufficient belt storage capacity leads to belt replacements, resulting in more joints, thinner belts, and in severe cases, even belt breakage, causing construction stoppages. Furthermore, for TBMs with multiple horizontal turns, a muck removal scheme using overlapping belt conveyors is generally employed. This overlapping process requires modifications, which in turn cause equipment downtime, significantly extending the construction period and reducing efficiency.
[0034] Therefore, how to improve the current weak storage capacity of existing belt conveyors and how to shorten the equipment downtime during the belt conveyor connection and transformation process have become urgent problems to be solved.
[0035] To address the shortcomings of the aforementioned technical status quo, those skilled in the art have conducted relevant research. For example, some implementations disclose a tensioned belt storage bin for storing and releasing conveyor belts in belt conveyors. This bin includes a storage bin frame and at least two storage assemblies stacked on the frame. Each storage assembly includes a redirecting unit, a sliding tensioning unit, and a tensioning drive unit. The redirecting unit is fixedly disposed at a first end of the storage bin frame. The sliding tensioning unit is disposed opposite to the redirecting unit and slidably disposed on the storage bin frame. The tensioning drive unit is disposed at a second end of the storage bin frame and drives the sliding tensioning unit to reciprocate on the storage bin frame. Multiple sets of rollers are provided on both the redirecting unit and the sliding tensioning unit, and the conveyor belt is sequentially wound around the rollers of each storage assembly. However, this implementation does not address the multi-level turning conditions encountered during tunnel construction.
[0036] Based on the aforementioned technical problems, this application provides a tape storage bin assembly and a tunnel boring machine, including a tape storage bin and at least two belt conveyors mounted on the tape storage bin. The tape storage bin includes a head tape storage bin and a tail tape storage bin. Compared to existing designs that only include a head tape storage bin, this significantly increases the storage length of the tape storage bin and reduces the number of belt splices, thereby reducing construction or production time lost due to filling the tape storage bin. By equipping the tail tape storage bin, during belt conveyor overlap modification, the belt can be continuously released from the belt conveyor, ensuring that tunneling and belt conveyor overlap are carried out simultaneously without downtime. This shortens equipment downtime during belt conveyor overlap modification, minimizes construction period, improves construction efficiency, and saves construction costs incurred due to downtime. It avoids the problems of weak tape storage capacity of the tape storage bin and relatively long equipment downtime during belt conveyor overlap modification in related technologies.
[0037] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention.

[0039] Example 1
[0040] Please refer to Figures 1 to 5 As shown, this application embodiment provides a storage bin assembly 100, which is installed in a tunnel boring machine. The tunnel boring machine is mainly used in tunnels to excavate the tunnel strata.
[0041] Tunnel boring machines include two types: open-face TBMs and slurry shield tunneling machines. This application embodiment primarily uses an open-face TBM as an example for illustration.
[0042] Additionally, it should be noted that the application scenario for the storage bin assembly 100 in this embodiment is a tunnel with multiple horizontal turns. For example, please refer to... Figure 1 and Figure 2 As shown, Figure 1 and Figure 2 These are schematic diagrams of a multi-level turning tunnel, which includes multiple horizontal sections and multiple turning sections, with the turning sections connecting two adjacent horizontal sections.
[0043] When a tunnel boring machine is excavating, one conveyor belt 120 can only excavate one horizontal section. When the horizontal section is completed and the machine turns to enter the next horizontal section, a second conveyor belt 120 needs to be arranged. Therefore, in the embodiments of this application, at least two continuous conveyor belts 120 are required.
[0044] The belt storage bin assembly 100 includes a belt storage bin 110, on which at least two belt conveyors 120 are disposed. It is understood that the belt storage bin 110 is used to temporarily store excess belt conveyors 120 before and after the retractable belt conveyors 120 to meet the needs of continuous forward or backward movement during tunneling.
[0045] The tape storage bin 110 includes a head tape storage bin 111 and a tail tape storage bin 112 arranged along the length of the tunnel boring device. The head tape storage bin 111 is located on the side closer to the tunnel boring end of the tunnel boring device, and the tail tape storage bin 112 is located on the side farther away from the tunnel boring end.
[0046] Understandably, the tunneling end, also known as the excavation end, is located at the very front of the tunnel boring machine.
[0047] In this embodiment, the belt conveyor 120 includes a first belt conveyor 121 and a second belt conveyor 122 as an example. The first belt conveyor 121 is located in front of the second belt conveyor 122 along the tunneling direction. Please refer to... Figure 3 As shown, when the tunnel boring machine is tunneling along the first horizontal section, the head storage bin 111 is connected to the side of the first belt conveyor 121 near the tunneling end, and the tail storage bin 112 is connected to the side of the first belt conveyor 121 away from the tunneling end.
[0048] During this process, the head belt storage bin 111 plays the main role in releasing belts to the first belt conveyor 121, while the tail belt storage bin 112 plays a supporting role in releasing belts to the first belt conveyor 121. The tunnel excavation device excavates through the first belt conveyor 121.
[0049] During this process, the head storage bin 111 and the first belt conveyor 121 are connected; the connection position can be referred to... Figure 3 The location at point A in the middle is shown.
[0050] Please continue to refer to Figure 4 As shown, when the tunnel boring machine completes the excavation of the first horizontal section and turns into the second horizontal section, the head belt storage bin 111 is removed from the first belt conveyor 121. The head belt storage bin 111 stops feeding belt onto the first belt conveyor 121, while the tail belt storage bin 112 continues to feed belt onto the first belt conveyor 121. In other words, during this process, the tail belt storage bin 112 plays the main role in feeding belt onto the first belt conveyor 121, and the TBM can still use the tail belt storage bin 112 for tunneling without stopping.
[0051] During this process, the head storage bin 111 and subsequently the first belt conveyor 121 are in a disassembled state. The disassembly location can be referred to... Figure 4 The location at point B is shown.
[0052] Meanwhile, please continue to refer to Figure 5 As shown, the second conveyor belt 122 is connected between the tail belt storage bin 112 and the first conveyor belt 121. The first conveyor belt 121 and the second conveyor belt 122 are fixedly connected. The removed head belt storage bin 111 is moved to the end of the second conveyor belt 122 near the side of the first conveyor belt 121. At this time, the head belt storage bin 111 begins to play the main role in releasing belt onto the second conveyor belt 122, while the tail belt storage bin 112 plays a supporting role in releasing belt onto the second conveyor belt 122. The tunnel boring machine advances through the second conveyor belt 122.
[0053] It should be noted that after the first belt conveyor 121 and the second belt conveyor 122 are fixedly connected, that is, at this time, the first belt conveyor 121 is a fixed belt conveyor 120. The fixed belt conveyor 120 means that the first belt conveyor 121 can only be used to transport slag and can no longer play the role of continuous belt feeding and tunneling.
[0054] Therefore, in this embodiment of the application, the belt storage bin 110 includes a head belt storage bin 111 and a tail belt storage bin 112. Compared with the existing mode that only includes the head belt storage bin 111, the storage length of the belt storage bin 110 can be greatly increased, and the number of belt joints between belt conveyors in the belt storage bin 110 can be reduced, thereby reducing the construction or production time lost due to filling the belt storage bin 110.
[0055] By equipping the belt storage bin 112 at the tail end, the belt of the belt conveyor 120 can be continuously released during the belt conveyor 120 overlap modification process, ensuring that the tunneling and belt conveyor 120 overlap are carried out simultaneously without stopping the machine. This shortens the equipment downtime during the belt conveyor 120 overlap modification, minimizes the construction period, improves construction efficiency, saves construction costs caused by downtime, and avoids the problems of weak belt storage capacity of the belt storage bin 110 and relatively long equipment downtime during the belt conveyor 120 overlap modification process in related technologies.
[0056] In one possible implementation, the belt conveyor 120 may include multiple belt conveyors, each corresponding to the excavation of one horizontal section, and the multiple belt conveyors 120 are arranged sequentially along the excavation direction. For example, in the embodiments of this application, the belt conveyor 120 may include two, three, four or more belt conveyors, and this embodiment does not further limit this.
[0057] When the tunnel boring machine excavates multiple horizontal sections in sequence, the next conveyor belt 120 of the multiple conveyor belts 120 overlaps between the tail belt storage bin 112 and the previous conveyor belt 120, and is fixedly connected to the previous conveyor belt 120.
[0058] After the head belt storage bin 111 is removed from the preceding belt conveyor 120, the tail belt storage bin 112 continues to feed belt onto the preceding belt conveyor 120. The head belt storage bin 111 is then moved to the end of the following belt conveyor 120 near the side of the preceding belt conveyor 120. The head belt storage bin 111 feeds belt onto the following belt conveyor 120, and the tail belt storage bin 112 cooperates in feeding belt onto the following belt conveyor 120. The tunnel boring machine then proceeds to tunnel via the following belt conveyor 120.
[0059] The bottom of the belt conveyor 120 is equipped with multiple rollers 150, and the belt conveyor 120 moves through the rollers 150.
[0060] In one possible implementation, an interlocking mechanism can be installed between any two adjacent conveyor belts 120. This interlocking mechanism can be controlled by interlocking logic or by a mechanical lock. Thus, when the tunnel boring machine suspends excavation, the two adjacent conveyor belts 120 are interlocked through the interlocking mechanism, thereby avoiding the risk of safety accidents due to misoperation.
[0061] In one possible implementation, please refer to Figure 5 As shown, it may also include a slag transport component 130, which is arranged between two adjacent belt conveyors 120.
[0062] The slag transport component 130 includes a receiving end 131 and a discharging end 132 connected together. The receiving end 131 is located at the end of the preceding belt conveyor 120 near the following belt conveyor 120, and the discharging end 132 is located at the end of the following belt conveyor 120 near the preceding belt conveyor 120. The discharging end 132 and the receiving end 131 are used to transport the slag on the belt conveyor 120 to the outside in sequence.
[0063] Taking the belt conveyor 120, which includes a first belt conveyor 121 and a second belt conveyor 122, as an example, when the head storage bin 111 on the first belt conveyor 121 is removed and moved to the head position of the second belt conveyor 122, the overlapping part is modified. A receiving end 131 is added to the end of the first belt conveyor 121 near the second belt conveyor 122, and a discharge end 132 is added to the end of the second belt conveyor 122 near the first belt conveyor 121. At the same time, the first belt conveyor 121 is changed into a fixed belt conveyor 120.
[0064] By including the excavation transport component 130, the excavation generated during the tunneling process can be transported to the outside in a timely manner. The outside can be the outside of the tunnel or the outside of the tunnel excavation device.
[0065] In one possible implementation, please refer to Figures 3 to 5 As shown, it may also include an end discharge component 140, which is disposed on the side of the first belt conveyor 121 away from the slag transport component 130, and is used to receive slag transported via the slag transport component 130.
[0066] It is understandable that the end unloading component 140 is located at the outermost end of the first belt conveyor 121. This ensures that all the slag on the belt conveyor 120 can be unloaded into the end unloading component 140, and also makes it easier for the operator to clean it.
[0067] The structure, shape, quantity, and location of the slag transport component 130 and the end unloading component 140 are not further limited. For example, the slag transport component 130 can be a transport trolley and the end unloading component 140 can be an unloading bin.
[0068] It can be added that a cleaning device, such as a water bottle, spray bottle, or water pipe, can be installed at the outermost end of the first belt conveyor 121 to facilitate timely cleaning of the belt conveyor 120.
[0069] In one possible implementation, a drive unit may also be included, which is disposed on the belt storage bin 110, electrically connected to the belt conveyor 120, and used to drive the belt conveyor 120 to move.
[0070] For example, the drive unit may be provided only on the head tape storage compartment 111, or the drive unit may be provided only on the tail tape storage compartment 112, or the drive unit may be provided on both the head tape storage compartment 111 and the tail tape storage compartment 112.
[0071] It should be noted that the driving component in the embodiments of this application can be a drive motor.
[0072] The following describes the operation of the storage bin assembly 100 in a multi-level turning tunnel:
[0073] Please refer to Figure 3 As shown, this is the initial state of the continuous belt conveyor 120. At this time, there is only one belt conveyor 120 (the first belt conveyor 121). The head belt storage bin 111 is located at the front end of the first belt conveyor 121, and the tail belt storage bin 112 is located at the rear end of the first belt conveyor 121. The arrangement of the two belt storage bins 110 can greatly increase the belt storage capacity of the belt storage bins 110. In straight sections and turning sections, the head belt storage bin 111 mainly works to release the belt, and the tail belt storage bin 112 assists in releasing the belt.
[0074] Please continue to refer to Figure 4 As shown, when the tunneling reaches a horizontal plane, a second belt conveyor 120 (second belt conveyor 122) needs to be installed. At this time, the head storage bin 111 on the first belt conveyor 121 needs to be removed. The first belt conveyor 121 can use the tail storage bin 112 for tunneling. When the head storage bin 111 is moved to the next station, the joint is modified. The first belt conveyor 121 adds a receiving end 131, and the second belt conveyor 122 adds a discharging end 132, thus changing the first belt conveyor 121 into a fixed belt conveyor 120.
[0075] Please continue to refer to Figure 5 As shown, after the modification is completed, the tunnel boring machine will operate according to... Figure 5 The tunneling continued in the same manner.
[0076] Example 2
[0077] This application provides a tunnel boring machine for use in tunnels. The tunnel boring machine includes a tunnel boring machine body and a tape storage bin assembly 100, which is disposed in the tunnel boring machine body.
[0078] Taking a TBM (tunnel boring machine) as an example, the tunneling device body can be the outer shell of the tunnel boring machine. The outer shell has a receiving cavity, and the tape storage bin assembly 100 is set in the receiving cavity.
[0079] The tunneling device body may be equipped with a control component, which is electrically connected to the tape storage bin 110 of the tape storage bin assembly 100. By including the control component, the control component can control the start-up or pause-up of tape release in the tape storage bin 110.
[0080] It should be noted that the control components can be control switches, etc.
[0081] This application provides a tape storage bin assembly 100 and a tunnel boring device, including a tape storage bin 110 and at least two belt conveyors 120 disposed on the tape storage bin 110. The tape storage bin 110 includes a head tape storage bin 111 and a tail tape storage bin 112. Compared with the existing mode that only includes the head tape storage bin 111, the storage length of the tape storage bin 110 can be greatly increased, and the number of belt joints between the belt conveyors in the tape storage bin 110 can be reduced, thereby reducing the construction or production time lost due to filling the tape storage bin 110. By equipping the belt storage bin 112 at the tail end, the belt of the belt conveyor 120 can be continuously released during the belt conveyor 120 overlap modification process, ensuring that the tunneling and belt conveyor 120 overlap are carried out simultaneously without stopping the machine. This shortens the equipment downtime during the belt conveyor 120 overlap modification, minimizes the construction period, improves construction efficiency, saves construction costs caused by downtime, and avoids the problems of weak belt storage capacity of the belt storage bin 110 and relatively long equipment downtime during the belt conveyor 120 overlap modification process in related technologies.
