[0002] Currently, the slope of inclined shafts excavated by full-face rock tunnel boring machines (TBMs) is relatively shallow, and the trailer's steel wheels usually run on tracks, which generally prevents the trailer from slipping. However, as the slope of the inclined shaft increases, the sliding friction of the trailer is insufficient to prevent it from sliding, making it impossible to ensure that the entire machine does not slide, thus affecting the personal safety of on-site workers. Existing technology is unable to limit the sliding of the auxiliary equipment behind the TBM in extremely steep shafts.

[0003] With the continuous emergence of difficult and steep inclined shaft excavation projects, existing construction technology is no longer capable of coping with inclined shaft projects that require high excavation efficiency, have a steep inclined shaft slope, are soft surrounding rock, and have an ineffective support system.

[0046] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0047] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0048] Please refer to Figure 1 , Figure 1 This is a schematic structural diagram of the rear-mounted anti-slip device provided in an embodiment of the present application.

[0049] In the first specific embodiment, the present application provides a rear-mounted anti-slip device for a tunnel boring machine (hereinafter referred to as the rear-mounted anti-slip device), which mainly includes two parts: a fixed component 2 and a movable component 3. The fixed component 2 and the movable component 3 are arranged at different positions. Through the action of the fixed component 2 on the movable component 3, the rear-mounted trailer 1 is prevented from slipping in the inclined shaft.

[0050] In this embodiment, the fixed component 2 is a structure that functions to block the movable component 3. The fixed component 2 is arranged along the inclined shaft. The fixed component 2 should be arranged along the entire length of the inclined shaft to provide an anti-slip effect on the inclined shaft.

[0051] The movable component 3 is installed on the rear supporting trailer 1, and the movable component 3 moves on the inclined shaft together with the rear supporting trailer 1. The movable component 3 includes a telescopic part, which can be extended when resetting to achieve the purpose of preventing slipping when the telescopic part is reset.

[0052] The rear-mounted anti-slip device prevents the rear-mounted trailer 1 from slipping by blocking the telescopic part that extends when the movable component 3 is reset through the fixed component 2. Since the anti-slipping is achieved by the action of the fixed component 2 on the movable component 3, the environment of the inclined shaft, such as geology and angle, will not interfere with the anti-slipping of this method. Therefore, the structure and function are stable, can overcome many conditions and restrictions, and are widely used. Even in inclined shafts with extremely large slopes, a high safety factor can be guaranteed, ensuring that the rear-mounted part of the tunnel boring machine is in a stable position before and after stepping and there is no risk of backward slipping.

[0053] In some embodiments, please refer to Figure 2 , Figure 2 This is a schematic structural diagram of the first anti-tilt assembly provided in an embodiment of the present application.

[0054] In this embodiment, the rear-mounted anti-slip device further includes a first anti-tilt assembly 4, through which the rear-mounted trailer 1 is prevented from overturning in a large-diameter inclined shaft.

[0055] The first anti-tilt assembly 4 includes a support 411, a first driving member 412 and a first top plate 413. The support 411 is installed on the top of the rear supporting trailer 1, the first driving member 412 is installed on the support 411, and the driving end of the first driving member 412 is connected to the first top plate 413. The first driving member 412 drives the first top plate 413 to tighten the wall of the large-diameter inclined shaft.

[0056] Specifically, this embodiment does not limit the number of first anti-tilt assemblies 4. That is, the number of first anti-tilt assemblies 4 can be a pair of two as shown in the figure, with the two first anti-tilt assemblies 4 arranged symmetrically on the top of the rear supporting trailer 1. Other numbers and arrangements are also possible and fall within the scope of the description of this embodiment. The support 411 is fixed to the top of the rear supporting trailer 1. The first driving member 412 can be a powered telescopic mechanism such as a cylinder, with the cylinder body fixed to the support 411 and the rod body fixed to the first top plate 413. The cylinder is used to support the first top plate 413 against the inclined shaft wall. After adjustment, the first top plate 413 is pressed against the inner wall of the inclined shaft and locked under pressure.

[0057] In some embodiments, please refer to Figure 3 , Figure 3 A schematic structural diagram of the second anti-tilt assembly provided in an embodiment of the present application.

[0058] In this embodiment, the rear-mounted anti-slip device also includes a second anti-tilt component 5. Different from the first anti-tilt component 4, the second anti-tilt component 5 is used to prevent the rear-mounted trailer 1 from overturning in a small-diameter inclined shaft.

[0059] The second anti-tilt assembly 5 includes a first base 511, a second driving member 512, a second base 513 and a second top plate 514. The first base 511 and the second base 513 are installed on the side of the rear supporting trailer 1. The first end of the second top plate 514 is rotatably installed on the second base 513. The second end of the second top plate 514 is connected to the driving end of the second driving member 512. The second driving member 512 is installed on the first base 511. The second top plate 514 is driven by the second driving member 512 to support the wall of the small-diameter inclined shaft.

[0060] Specifically, this embodiment does not limit the number of second anti-tilt assemblies 5. That is, the number of second anti-tilt assemblies 5 can be a pair of two as shown in the figure, with the two second anti-tilt assemblies 5 arranged symmetrically on the left and right sides of the rear supporting trailer 1. Other numbers and arrangements are also possible and should fall within the scope of the description of this embodiment. The first base 511 and the second base 513 are fixed to the side of the rear supporting trailer 1. The second driving member 512 can be a powered telescopic mechanism such as a cylinder. The cylinder body is hinged to the first base 511, and the rod body is hinged to the second top plate 514. The cylinder rotates the second top plate 514 to support the inclined shaft wall. After adjustment, the second top plate 514 is pressed against the inner wall of the inclined shaft and locked under pressure.

[0061] It should be noted that in addition to its stable structure and function, even in extremely steep inclined shafts and having a high safety factor, the rear-mounted anti-slip device also achieves and improves its ability to adapt to inclined shafts of different diameters through the design of different anti-overturning mechanisms.

[0062] In some embodiments, please refer to Figure 4, Figure 4 A schematic diagram of the structure of the adjustment component provided in an embodiment of the present application.

[0063] In this embodiment, the rear-mounted anti-slip device further includes an adjusting component 6 , which is connected to the movable component 3 , and the position of the movable component 3 on the rear-mounted trailer 1 is driven and adjusted by the adjusting component 6 .

[0064] There are many forms of the adjustment component 6, such as the driving method and the connection method; it can adopt a power telescopic mechanism such as a cylinder, and can drive one or more movable components 3 simultaneously or independently, which should all fall within the scope of the description of this embodiment.

[0065] It should be noted that in addition to having stable structural functions and adaptability to inclined shafts of different diameters, the rear-mounted anti-slip device also has an adjustment function. The adjustment component 6 can be adjusted forward and backward in the direction of movement of the rear-mounted trailer 1 along the inclined shaft. Even if the inclined shaft is an arc-shaped excavation path, the effect of the fixed component 2 on the movable component 3 is always guaranteed, with stable functions and reliable performance.

[0066] For example, in the first embodiment of the adjustment component 6:

[0067] Please refer to Figure 5 , Figure 5 A schematic structural diagram of the adjustment component and the movable component provided for the first embodiment of the present application.

[0068] In this embodiment, the adjustment component 6 includes a first power member 611 and a movable frame 612. The first power member 611 is installed on the rear supporting trailer 1. The driving end of the first power member 611 is connected to the movable frame 612. The movable frame 612 can move relative to the rear supporting trailer 1. The movable component 3 is installed on the movable frame 612 to realize the installation of the movable component 3 on the rear supporting trailer 1.

[0069] In this embodiment, the first power member 611 can adopt a power telescopic mechanism such as a cylinder, and its number is not limited. The telescopic action of the cylinder drives the mobile frame 612 to move, and then drives the movable component 3 on the mobile frame 612 to move, thereby realizing the adjustment of the position of the movable component 3 on the rear supporting trailer 1.

[0070] The movable assembly 3 includes a plurality of monomers, all of which are mounted on the movable frame 612. When the first power member 611 is actuated, the positions of all monomers of the movable assembly 3 are adjusted synchronously to ensure the anti-slip effect.

[0071] For example, in the second embodiment of the adjustment component 6:

[0072] Please refer to Figure 6 and Figure 7 , Figure 6Schematic diagram of the structure of the adjustment component and the movable component provided in the second embodiment of the present application Figure 1 , Figure 7 Schematic diagram of the structure of the adjustment component and the movable component provided in the second embodiment of the present application Figure 2 .

[0073] In this embodiment, the adjustment component 6 includes a second power member 621 and a sliding member 622. The second power member 621 is installed on the rear supporting trailer 1. The driving end of the second power member 621 is connected to the sliding member 622, and the rear supporting trailer 1 is provided with a slide rail 111 for the sliding member 622 to slide. The movable component 3 is installed on the sliding member 622 to realize the installation of the movable component 3 on the rear supporting trailer 1.

[0074] In this embodiment, the second power member 621 can adopt a power telescopic mechanism such as a cylinder. The difference from the first adjustment component 6 is that the second power member 621, the sliding member 622 and the monomers of the movable component 3 correspond one to one, that is, each monomer is connected to a sliding member 622, and each sliding member 622 is driven by a second power member 621, thereby driving the monomers of the movable component 3 to move independently rather than synchronously. This can meet the needs of special situations such as arc paths, and can control different monomers to adjust their positions independently according to specific conditions such as the arc angle, thereby ensuring the anti-slip effect.

[0075] For example, in the embodiment of the first movable component 3:

[0076] Please continue to refer to Figure 1 In this embodiment, the movable component 3 includes at least one monomer, and a linear telescopic member 311 is used as the telescopic member; there is no limit on the number of monomers, and at least one monomer includes a linear telescopic member 311 and a first elastic member 312. The linear telescopic member 311 is connected to the first elastic member 312. Under the action of the first elastic member 312, the linear telescopic member 311 extends straightly when resetting and is blocked by the fixed component 2.

[0077] It should be noted that, in different embodiments, the specific configurations of the linear telescopic member 311 and the first elastic member 312 are different.

[0078] Specifically, in an embodiment where the adjustment component 6 is not provided, the linear telescopic member 311 and the first elastic member 312 are directly provided on the rear supporting trailer 1. At this time, a base for installing the linear telescopic member 311 and the first elastic member 312 is provided on the rear supporting trailer 1. The linear telescopic member 311 slides in the hole of the base and can be extended. The first elastic member 312 can be a compressed spring connected between the base and the linear telescopic member 311, so that the linear telescopic member 311 is extended in the initial state. At this time, it can be blocked by the fixing component 2. After being compressed and retracted, the linear telescopic member 311 can be reset under the action of the first elastic member 312, that is, extended again.

[0079] In the embodiment of setting the adjustment component 6, according to different implementation methods of the adjustment component 6, in the first implementation method of the adjustment component 6, the linear telescopic member 311 and the first elastic member 312 are arranged on the movable frame 612, and the other contents should be similar to the above and will not be repeated here; in the second implementation method of the adjustment component 6, the linear telescopic member 311 and the first elastic member 312 are arranged on the sliding member 622, and the other contents should be similar to the above and will not be repeated here.

[0080] For example, in the embodiment of the second movable component 3:

[0081] Please continue to refer to Figure 5 In this embodiment, the movable component 3 includes at least one monomer, and a rotating telescopic member 321 is used as the telescopic member; there is no limit to the number of monomers, and at least one monomer includes a rotating telescopic member 321 and a second elastic member 322. The rotating telescopic member 321 is rotatable, and the rotating telescopic member 321 is connected to the second elastic member 322. Under the action of the second elastic member 322, the rotating telescopic member 321 rotates and extends when resetting, and is then blocked by the fixed component 2.

[0082] It should be noted that, in different implementations, the specific configurations of the rotating and telescopic member 321 and the second elastic member 322 are different.

[0083] Specifically, in an embodiment where the adjustment component 6 is not provided, the rotating telescopic member 321 and the second elastic member 322 are directly provided on the rear supporting trailer 1. At this time, a base for installing the rotating telescopic member 321 and the second elastic member 322 is provided on the rear supporting trailer 1. The rotating telescopic member 321 rotates on the base. The second elastic member 322 can be a torsion spring or a tensioned spring, which is connected between the base and the rotating telescopic member 321. After the rotating telescopic member 321 rotates to the extreme position in the initial state, it is positioned by the stopper on the base. At this time, it can be blocked by the fixed component 2. When the force is reversed, the rotating telescopic member 321 can be reset under the action of the rear second elastic member 322, that is, it rotates to the extreme position again.

[0084] In the embodiment of setting the adjustment component 6, according to different implementation methods of the adjustment component 6, in the first implementation method of the adjustment component 6, the rotating telescopic component 321 and the second elastic component 322 are set on the movable frame 612, and the other contents should be similar to the above and will not be repeated here; in the second implementation method of the adjustment component 6, the rotating telescopic component 321 and the second elastic component 322 are set on the sliding component 622, and the other contents should be similar to the above and will not be repeated here.

[0085] For example, in the embodiment of the first fixing component 2:

[0086] Please refer to Figure 8 , Figure 8 A schematic structural diagram of the fixing assembly provided for the first embodiment of the present application.

[0087] In this embodiment, the fixed assembly 2 is a steel nodule and box structure that can be anchored to the bottom of the inclined shaft section by section. The fixed assembly 2 includes a stopper 211 and a first fixing member 212. The stopper 211 is located on the outside of both sides to block the telescopic member of the movable assembly 3 to prevent slipping.

[0088] Specifically, the fixing assembly 2 uses large-sized I-beams as the main load-bearing components, and the first fixing part 212 at the bottom uses a concave arc plate and is anchored at the bottom of the inclined shaft to keep the steel structure fixed at the bottom of the inclined shaft. It can be installed upward section by section along the inclined shaft to provide anti-slip and stepping reaction force.

[0089] It should be noted that the fixing component 2 in this embodiment is applicable to the implementation of the first movable component 3 and the second movable component 3 described above.

[0090] For example, in the embodiment of the third movable component 3 and the second fixed component 2:

[0091] Please refer to Figures 9 to 11 ,in, Figure 9 This is a schematic diagram of the structure of the fixed component and the movable component provided in the third embodiment of the present application. Figure 10 This is a schematic diagram of the structure of the fixing assembly provided in the third embodiment of the present application. Figure 11 A schematic structural diagram of the active component provided for the third embodiment of the present application.

[0092] In this embodiment, similar to other embodiments, the movable component 3 also includes at least one monomer. The difference is that the monomer includes a retractable wedge-shaped telescopic member 331 , and the fixed component 2 includes a wedge-shaped member 221 matching the wedge-shaped telescopic member 331 .

[0093] In the uphill direction of the rear supporting trailer 1, the cross-section of the wedge-shaped telescopic member 331 gradually decreases and the cross-section of the wedge-shaped member 221 gradually increases, so that when the rear supporting trailer 1 slides down the slope, the wedge-shaped telescopic member 331 is extended and blocked by the wedge-shaped member 221 of the fixed assembly 2.

[0094] It should be noted that the wedge-shaped telescopic member 331 can be telescopic in a variety of ways, including vertical telescopic, which can be achieved by using a third power member similar to the above-mentioned power telescopic mechanism. The wedge-shaped telescopic member 331 is connected to the rear-mounted trailer 1 via the third power member, providing an upward and downward adjustment function. The third power member is used to adjust the engagement and separation of the wedge-shaped telescopic member 331 and the wedge member 221. After the third power member aligns the wedge-shaped telescopic member 331 with the wedge member 221, anti-slip is achieved. Alternatively, the wedge-shaped telescopic member 331 can be telescopic left and right, which can be achieved by using a third elastic member similar to the above-mentioned spring. In this case, when the rear-mounted trailer 1 is climbing uphill, the wedge-shaped telescopic member 331 is pushed back by the wedge member 221 and is unobstructed. When sliding downhill, the wedge-shaped telescopic member 331 is extended back to prevent slipping. Furthermore, the third movable assembly 3 can be combined with the above-mentioned third power member and third elastic member. Embodiments of the third movable assembly 3 combined with the third power member and third elastic member should also fall within the scope of the description of this embodiment.

[0095] The present application also provides a tunnel boring machine, which relates to the application field of TBM in ultra-large slope vertical shafts. It has the function of preventing the entire TBM from sliding backward and ensuring the advancement of the entire TBM under extreme conditions.

[0096] In this embodiment, the tunnel boring machine includes the above-mentioned rear-mounted anti-slip device, so that in the field of ultra-large slope shaft TBM, it can adapt to different geological conditions and different shaft slopes, and there is no risk of backward sliding before and after the TBM changes steps, and reliable construction is achieved; in addition, it should have all the beneficial effects of the above-mentioned rear-mounted anti-slip device, which will not be repeated here one by one.

[0097] It should be noted that the above-mentioned rear-mounted anti-slip device is not limited to one rear-mounted trailer 1. Different rear-mounted trailers 1 can be prevented from slipping by the rear-mounted anti-slip device. The rear-mounted trailers 1 are connected by oil cylinders and have a self-stepping function. The rear-mounted self-stepping can be achieved in environments such as soft surrounding rock, meeting the requirements of TBM whole-machine propulsion under extreme conditions.

[0098] It should be noted that many of the components mentioned in this application are universal standard parts or components known to those skilled in the art, and their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods.

[0099] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0100] The above is a detailed introduction to the tunnel boring machine and its subsequent anti-slip device provided by this application. This article uses specific examples to illustrate the principles and implementation methods of this application. The description of the above embodiments is only intended to help understand the method and core concept of this application. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of this application, several improvements and modifications can be made to this application, and these improvements and modifications also fall within the scope of protection of the claims of this application.
