Description

Technical Field

[0001] This invention relates to the field of tunnel boring machine starting / receiving technology, and in particular to a guide platform device for starting or receiving tunnel boring machines. Background Technology

[0002] In recent years, with the development of tunnel boring machine (TBM) construction technology, especially the maturity of technologies such as connecting tunnel TBMs and inclined shaft shield tunneling, TBMs can operate in confined spaces like tunnels. When the starting site installation position cannot be adapted to the tunnel axis, the starting and receiving guide rails need to have the function of adjusting a certain angle. For example, when the tunnel collapses, the TBM can start from the tunnel wall in the intact section of the tunnel and excavate a side passage, or the TBM can start from the ground and excavate the tunnel at an angle downwards.

[0003] Existing launching / receiving guide devices are mostly single-position fixed launching / receiving guidance functions. When the launching / receiving posture needs to be adjusted, the tunneling machine and launching / receiving guide must be reconstructed and fixed, or even a new launching / receiving guide must be designed, which greatly extends the construction cycle and increases construction costs. Therefore, various launching / receiving guide devices have gradually emerged in the existing technology: For example, the invention patent application with publication number CN 107435540A discloses a shield tunneling launching guide device that can be quickly adjusted, but it can only realize the vertical posture adjustment of the tunneling machine, and it occupies too much space in the vertical direction, making it unsuitable for launching scenarios with limited vertical space. Another example is the utility model patent with authorization publication number CN 215057399U, which discloses a TBM launching guide structure. Although it is suitable for launching scenarios with limited space inside the tunnel, and the launching guide is small in size, has high rigidity, and strong overall integrity, it cannot adjust the launching posture. If the launching posture needs to be adjusted, the guide rails need to be reconstructed, poured, adjusted, and fixed.

[0004] Therefore, it is necessary to design a transmitter / receiver station that can quickly adjust the starting / receiving attitude with multiple degrees of freedom and is suitable for starting in confined spaces.

[0005] It should be noted that the above technical information is the result of the applicant's inventive analysis. This explanation is only intended to deepen the understanding of the general background technology of this utility model by those skilled in the art, and should not be regarded as an admission or implication in any form that the following technical information constitutes prior art known to those skilled in the art. Summary of the Invention

[0006] To address the shortcomings in the aforementioned background technology, this invention proposes a guide platform device for starting or receiving tunneling machines. The technical problem to be solved is: how to quickly and with multiple degrees of freedom adjust the starting / receiving attitude of the tunneling machine, and how to make it suitable for starting / receiving in confined spaces.

[0007] The technical solution of this invention is as follows:

[0008] A guide platform device for starting or receiving a tunneling machine includes a guide platform bracket and a guide platform base connected by a linkage mechanism and a linear drive mechanism. The linear drive mechanism drives the linkage mechanism, thereby causing the guide platform bracket to rise and fall and / or pitch relative to the guide platform base. At least one side of the guide platform base is connected to a lateral reaction base via a linkage mechanism and a linear drive mechanism. The linear drive mechanism drives the linkage mechanism, thereby causing the guide platform base to move laterally and / or pitch left and right relative to the construction site.

[0009] The beneficial effects of this technical solution are as follows:

[0010] Achieving multi-degree-of-freedom attitude adjustment and completely solving the defects of fixed attitude: Unlike existing fixed attitude guides, this solution uses two independent "linkage mechanism + linear drive mechanism" combinations to achieve multi-dimensional attitude adjustment of vertical plane lifting, pitch + horizontal plane lateral movement, and head swing, covering the core attitude adjustment needs of tunneling machine starting / receiving. It can adapt to complex construction scenarios such as mismatch between the starting site and the tunnel axis, excavation of side detour channels, and oblique downward starting, without the need to redesign the guide for changes in attitude requirements.

[0011] Rapid adjustment significantly reduces construction time: The linear drive mechanism directly drives the linkage mechanism, eliminating the need for disassembly, pouring, and secondary fixing of the guide platform's main structure. The attitude adjustment can be completed simply by controlling the extension and retraction of the linear drive mechanism. Compared to the existing technology that requires rebuilding and pouring guide rails, the adjustment time is reduced from several days / weeks to several hours, greatly improving construction efficiency.

[0012] The linkage mechanism optimizes space utilization and adapts to confined construction spaces: Existing technologies only offer height adjustment and have significant space encroachment. This solution uses a linkage mechanism as the transmission and support carrier. The linkage is a hinged folding / extending structure, resulting in minimal expansion of the overall structure's vertical and horizontal dimensions during adjustment. This makes it suitable for launching / receiving scenarios with limited height and horizontal space, such as tunnels and connecting passages, thus overcoming the application limitations of confined spaces.

[0013] Reduce overall construction costs: No need to repeatedly manufacture, pour, and install guide platforms, reducing the consumption of steel and concrete materials. At the same time, it saves the costs of manual demolition, reconstruction, and calibration, and avoids the indirect construction costs caused by the delay in construction period due to guide platform reconstruction. The total life cycle cost is far lower than that of fixed guide platforms and single-dimensional adjustable guide platforms.

[0014] The attitude adjustment is highly continuous and controllable: the linear drive mechanism can achieve stepless extension and retraction, and with the smooth transmission of the linkage mechanism, the attitude adjustment of the guide bracket and guide base is a continuous and gradual process, which can accurately match the preset starting / receiving axis of the tunneling machine. The adjustment accuracy is better than the gear adjustment of the assembled fixed guide rail.

[0015] Based on the above technical solution, as a preferred technical solution for the guide platform device for starting and receiving tunneling machines, the guide platform base includes two base foundations arranged symmetrically on the left and right, and the guide platform bracket includes two inclined support plates corresponding to the upper and lower of the two base foundations respectively, and the inclined support surfaces of the two inclined support plates are symmetrical on the left and right.

[0016] The further beneficial effects of this technical solution are as follows:

[0017] Symmetrical structure enhances stress balance and operational stability: The left and right symmetrical base foundations and symmetrical diagonal bracing plates ensure that the load of the tunneling machine and the dynamic load during the adjustment process are evenly distributed on both sides of the structure, avoiding problems such as unilateral overload, structural skew, and stress concentration. This also improves the overall rigidity of the guide platform, prevents deformation and tilting during long-term use, and ensures the guiding accuracy of the tunneling machine's starting / receiving.

[0018] Adapted to the tunneling machine body structure, improving the guide fit: The symmetrical diagonal bracing surfaces can precisely fit the symmetrical contour of the lower part of the tunneling machine body, increasing the contact support area, reducing local pressure, and preventing the tunneling machine body from being worn or deformed due to excessive local stress. At the same time, the symmetrical support can prevent the body from shifting laterally and strengthen the guide constraint effect.

[0019] Modular structure simplifies processing and assembly: The base foundations and diagonal bracing plates on both sides are symmetrical and identical, which can be standardized and mass-produced. The parts are highly interchangeable, reducing processing difficulty and manufacturing costs. There is no need to distinguish between left and right components during on-site assembly, which improves assembly efficiency and reduces assembly errors.

[0020] Inheriting all the advantages of the above schemes, while enhancing structural reliability: retaining the core advantages of multi-degree-of-freedom adjustment, rapid adjustment, and adaptation to narrow spaces, optimizing mechanical performance through symmetrical structure, extending the service life of the device, and reducing the frequency of later maintenance.

[0021] Based on the above technical solutions, as a preferred technical solution for the guide platform device for starting and receiving tunneling machines, the linkage mechanism 1 includes two linkage assemblies 1 respectively connected between the corresponding base foundation and the inclined support plate, and the linear drive mechanism 1 includes two linear drive assemblies 1 respectively connected between the corresponding linkage assembly 1 and the inclined support plate, or two linear drive assemblies 1 respectively connected between the corresponding linkage assembly 1 and the base foundation.

[0022] The further beneficial effects of this technical solution are as follows:

[0023] Dual-side independent drive enables precise pitch adjustment: Two independent linkage assemblies on the left and right sides, plus a linear drive assembly, can control the lifting and lowering amplitude of the inclined support plates on both sides. By measuring the difference in the extension and retraction of the drive components on both sides, the pitch angle of the guide bracket can be precisely adjusted, solving the problem that a single drive cannot precisely control pitch and that inconsistent heights on both sides are likely to occur. This adapts to the fine-tuning needs of the tunneling machine's pitch attitude.

[0024] The drive layout is highly flexible and adaptable to different spatial conditions: the linear drive component can be hinged between the connecting rod component and the brace plate, or between the connecting rod component and the base foundation. The drive installation position can be flexibly selected according to the specific constraints (vertical / lateral clearance) of the narrow space on site, further improving the adaptability of the device to different narrow construction scenarios.

[0025] Controllable synchronicity of adjustment response: The dual-side drive components can be synchronously controlled to achieve pure lifting and asynchronously controlled to achieve pitch. The adjustment mode can be freely switched, taking into account both the needs of rapid overall lifting and precise pitch adjustment.

[0026] Based on the above technical solutions, as a preferred technical solution for the guide platform device for starting and receiving tunneling machines, the first link assembly includes two link 1s that are hinged together, and the link 1s are hinged to the inclined brace plate. One link 1 is hinged to the base foundation, and the other link 1 is slidably connected to the base foundation. The first linear drive assembly includes two linear drive components 1, which are respectively hinged between the two link 1s and the inclined brace plate or respectively hinged between the two link 1s and the base foundation.

[0027] The further beneficial effects of this technical solution are as follows:

[0028] The double-link articulated + sliding composite structure amplifies the adjustment stroke: The two articulated links form a scissor link structure, which, with one end articulated and the other sliding, allows for a larger lifting and pitch adjustment stroke of the guide bracket in situations where the linear drive component occupies a relatively small space. This solves the problem that small-stroke drive components cannot meet the needs of large height / angle adjustment. At the same time, the drive component is small in size, further reducing space occupation.

[0029] High transmission efficiency and low energy loss: The first connecting rod is a pure rigid hinge transmission without intermediate transmission components such as gears and chains, resulting in low friction loss. The power of the linear drive component can be directly converted into the attitude adjustment action of the bracket. The transmission efficiency is higher than that of indirect transmission structures, reducing the energy consumption of the drive system.

[0030] Sliding connection releases structural freedom and avoids jamming: A connecting rod slides to the base foundation, which can release the constraint stress of the hinge structure. During the adjustment process, the connecting rod is free from rigid jamming or sticking, and the movement is smooth and without jamming, which improves the stability of the adjustment process and the service life of the mechanism.

[0031] The dual drive components correspond to dual connecting rods, resulting in a reasonable force distribution: each linear drive component drives one connecting rod, and the driving load acts directly on the corresponding connecting rod, avoiding uneven force distribution and connecting rod deformation caused by a single drive component driving two connecting rods, thus improving the load-bearing capacity and adjustment accuracy of the mechanism.

[0032] Based on the above technical solutions, as a preferred technical solution for the guide platform device for starting and receiving tunneling machines, a sliding groove is provided on the base foundation, and a connecting rod that is slidably connected to the base foundation is hinged to a slider, and the connecting rod slides in cooperation with the sliding groove through the slider.

[0033] The beneficial effects of this technical solution are as follows:

[0034] The slider-slide pair features high sliding accuracy and low resistance: Slide one is a fixed guide structure on the base foundation, and slider one and slide one are in surface contact fit, resulting in high guiding accuracy. During the adjustment process, the sliding trajectory of connecting rod one is strictly controlled to avoid lateral movement and ensure the axial accuracy of lifting and pitch adjustment. Surface contact disperses pressure, resulting in low sliding friction resistance and reducing the load on linear drive component one.

[0035] The structure is easy to process and suitable for on-site construction: the slide rail can be directly grooved on the steel profile or steel plate of the base foundation, and the slider is a standard block component with mature processing technology. It does not require high-precision customized slide rails, reducing manufacturing costs and making it suitable for mass production of engineering equipment.

[0036] Wear-resistant and easy to maintain: The slider can be made of wear-resistant alloy, nylon and other composite materials. It can be replaced separately after wear without replacing the entire base or connecting rod. The maintenance cost is low and the replacement efficiency is high. The slide groove is an open structure, which makes it easy to clean up slag, dust and other impurities and avoids impurities from blocking the sliding pair.

[0037] High connection strength, suitable for heavy-duty working conditions: The matching structure of the slider and the groove can withstand the vertical heavy load of the tunneling machine, and there is no risk of derailment during the sliding process. It is suitable for the starting / receiving support requirements of large-tonnage tunneling machines.

[0038] Based on the above technical solutions, as a preferred technical solution for the guide platform device for starting and receiving tunneling machines, a connecting rod 1 that is slidably connected to the base foundation is hinged with a sliding groove 1, and a sliding rail 1 is provided on the base foundation, with the connecting rod 1 slidingly engaging with the sliding rail 1 through the sliding groove 1.

[0039] The beneficial effects of this technical solution are as follows:

[0040] The slide rail and slide groove are inverted for enhanced protection: the slide groove moves with the connecting rod, while the slide rail is fixed to the base. The inverted fit allows the slide groove to cover the slide rail, reducing the amount of slag, cement slurry, and dust entering the sliding pair in the construction environment, thus reducing the probability of impurities getting stuck and wear, and making it suitable for the harsh construction environment inside the tunnel.

[0041] Advanced guidance accuracy, suitable for high-precision adjustment scenarios: The slide rail can be made of high-precision rolled and machined guide rail, the matching gap between the slide groove and the slide rail can be controlled, the sliding straightness is higher, and the adjustment accuracy of the guide bracket lifting and pitching is further improved, meeting the starting guidance requirements of high-precision tunnel excavation.

[0042] Complementary structural stiffness and strong resistance to deformation: The fixed slide rail can enhance the local stiffness of the base foundation, while the moving slide groove can strengthen the structural strength of the connecting rod and the sliding end. The combination of the two ensures both sliding flexibility and improves the bending and deformation resistance of the sliding parts, and there is no structural deformation during long-term heavy-load use.

[0043] This solution complements and adapts to the above solutions, covering different working conditions: this solution is selected for scenarios with high dust levels and high protection requirements, while the above solutions are selected for scenarios with sensitive processing costs and simple structures, thus further expanding the device's scenario adaptability.

[0044] Based on the above technical solutions, as a preferred technical solution for the guide platform device for starting and receiving tunneling machines, the second linkage mechanism includes a second linkage assembly connected between the base foundation and the lateral reaction base, and the second linear drive mechanism includes a second linear drive assembly connected between the second linkage assembly and the lateral reaction base or a second linear drive assembly connected between the second linkage assembly and the base foundation.

[0045] The beneficial effects of this technical solution are as follows:

[0046] The horizontal adjustment is modular and does not interfere with the vertical adjustment: the second linkage mechanism and the second linear drive mechanism are independently responsible for the horizontal lateral movement and head adjustment, which are completely independent of the vertical lifting and pitch adjustment system of the above scheme. The two systems can be adjusted synchronously or separately without action interference. They can simultaneously complete the composite attitude adjustment of the vertical and horizontal planes, further improving the flexibility of multi-degree-of-freedom adjustment.

[0047] The lateral reaction base provides stable reaction force to ensure the reliability of lateral adjustment: The lateral reaction base is fixed to the construction site and provides reliable lateral support reaction force for the second linkage assembly and the second linear drive assembly, avoiding instability of the guide platform base during lateral movement and head swing adjustment, and solving the problem of no stable support for lateral adjustment in a narrow space.

[0048] Flexible drive layout, adaptable to narrow lateral spaces: The second linear drive component can be installed between the second connecting rod component and the lateral reaction base / base foundation. It can be flexibly arranged according to the lateral clearance of the tunnel and the boundary of the construction site, avoiding interference between the drive components and the tunnel wall and construction equipment, and enhancing adaptability to narrow spaces.

[0049] Inheriting all the aforementioned advantages of vertical adjustment, the system is improved to be a full-dimensional adjustment system: retaining all the beneficial effects of lifting and pitching adjustment, and adding lateral and tilting adjustment functions, forming a complete four-degree-of-freedom adjustment system with two dimensions in the vertical plane and two dimensions in the horizontal plane, which completely covers all the conventional attitude adjustment needs of the tunneling machine.

[0050] Based on the above technical solutions, as a preferred technical solution for the guide platform device for starting and receiving the tunneling machine, the second link assembly includes two link 2s that are hinged together, and the link 2s are hinged to the base foundation. One link 2 is hinged to the lateral reaction base, and the other link 2 is slidably connected to the lateral reaction base. The second linear drive assembly includes two linear drive components 2, which are respectively hinged between the two link 2s and the lateral reaction base or respectively hinged between the two link 2s and the base foundation.

[0051] The beneficial effects of this technical solution are as follows:

[0052] The transverse double-link structure amplifies the transverse adjustment stroke: It adopts a double-hinged link + sliding connection structure consistent with the link assembly, and realizes a large-stroke transverse movement and head adjustment of the guide table base under the small stroke extension and retraction of the linear drive component, which can meet the needs of correcting a large range of transverse axis deviation. At the same time, the drive component is small in size and does not take up extra transverse space.

[0053] Smooth lateral adjustment with no jamming: The connection between the two connecting rods, with one end hinged and the other sliding, releases the structural stress of lateral adjustment and avoids the stiffness and jamming caused by the hinge constraint. The lateral movement and head swing are continuous and stable, and the lateral position and head swing angle can be precisely adjusted.

[0054] Dual drive components drive independently, precisely controlling the swinging posture: two linear drive components drive two connecting rods respectively. By controlling the difference in the extension and retraction of the two drive components, the swinging angle of the guide platform base is precisely controlled, realizing fine adjustment of the axis deflection in the horizontal plane, which is suitable for the high-precision guidance requirements of tunnel curve section initiation and side passage excavation.

[0055] The mechanical structure and vertical system are unified, which facilitates standardized design: the second link assembly and the first link assembly have the same structural form, transmission principle and force mode, which facilitates the standardized design, simulation calculation and processing and manufacturing of the overall structure, reduces the research and development and production costs, and makes it easy for operators to master the adjustment logic.

[0056] Based on the above technical solution, as a preferred technical solution for the guide platform device for starting and receiving tunneling machines, a second sliding groove is provided on the transverse reaction base, and a second slider is hinged to the second connecting rod that is slidably connected to the transverse reaction base. The second connecting rod slides in cooperation with the second sliding groove through the second slider.

[0057] The beneficial effects of this technical solution are as follows:

[0058] The high precision of the lateral sliding pair ensures the lateral movement trajectory: the surface contact between slider two and slide groove two strictly constrains the lateral sliding trajectory of connecting rod two, avoiding radial movement when the guide base moves laterally or swings, ensuring the adjustment accuracy of the tunneling machine's lateral axis, and preventing the starting axis from deviating from the design route.

[0059] Low-cost adaptation to lateral heavy-duty sliding requirements: The slide groove is machined by slotting and the slider is modularly manufactured, which is inexpensive. At the same time, it can withstand the lateral load and dynamic load of the tunneling machine and guide platform as a whole, taking into account both economy and load-bearing capacity.

[0060] Easy maintenance and cleaning: The open slide block II structure facilitates the cleaning of slag and impurities in the tunnel. The slide block II can be quickly and individually replaced after wear, without affecting the overall use of the lateral adjustment system, thus reducing the difficulty of later operation and maintenance.

[0061] Standardization with vertical sliding structures improves spare parts versatility: Slider 2 and slide rail 2 can be designed with the same specifications as slider 1 and slide rail 1 in the above scheme, standardizing spare parts, reducing the types and quantities of spare parts on site, and facilitating on-site project management.

[0062] Based on the above technical solution, as a preferred technical solution for the guide platform device for starting and receiving tunneling machines, the connecting rod two, which is slidably connected to the base foundation, is hinged with a sliding groove two, and a sliding rail two is provided on the base foundation, with the connecting rod two slidingly engaging with the sliding rail two through the sliding groove two.

[0063] The beneficial effects of this technical solution are as follows:

[0064] Lateral sliding sub-high protection, suitable for harsh dust environment: The second slide groove moves with the second connecting rod and covers the second slide rail, effectively blocking construction dust and slurry from entering the sliding mating surface, greatly reducing the wear and jamming probability of the lateral adjustment mechanism, and can operate stably for a long time in the tunnel construction environment with high dust and high impurities.

[0065] High-precision lateral guidance to meet precision launch requirements: The second slide rail adopts a high-precision guide rail, and the second slide groove is precisely matched with the second slide rail. The lateral sliding straightness and position repeatability are high, and millimeter-level lateral position fine adjustment can be achieved to meet the launch / receive guidance requirements of small radius curved tunnels and high-precision communication channels.

[0066] Upgraded structural strength to accommodate heavy lateral loads: The second slide rail is rigidly connected to the base foundation, and the second slide groove is hinged to the second connecting rod. The mating surface has a large bearing area, which can withstand the lateral load and impact load of heavy-duty tunneling machines. The structure has no risk of deformation or derailment.

[0067] Improve the selection of the lateral sliding structure to cover all scenario requirements: There are two options to form a lateral sliding pair with the above-mentioned Scheme 9. For high protection and high precision scenarios, this scheme is selected, while for low cost and simple scenarios, the above-mentioned scheme is selected. The versatility and scenario coverage of the device are optimized.

[0068] This invention, through a composite structural design of a vertical linkage drive system (linkage mechanism one + linear drive mechanism one) and a horizontal linkage drive system (linkage mechanism two + linear drive mechanism two), systematically solves all the core defects of existing technologies from multiple dimensions, including core functions, structural performance, construction applications, economic costs, and scenario adaptability. The overall beneficial effects are summarized as follows:

[0069] Achieve rapid and precise adjustment with four degrees of freedom, completely breaking through the limitations of fixed posture: Integrate four major adjustment functions of lifting, pitching, lateral movement and head tilting to form a full-dimensional posture adjustment system. It can steplessly, continuously and precisely match any preset starting / receiving axis of the tunneling machine, adapting to all complex construction scenarios such as site axis mismatch, oblique starting, side detour passage, and starting in narrow space, without the need to redesign or pour guide platform.

[0070] Ultimately adaptable to confined construction spaces, expanding application boundaries: The entire process adopts a hinged linkage mechanism, with minimal expansion of the structural outline during adjustment and no oversized components. At the same time, the flexible arrangement design of the drive components and sliding pairs can adapt to scenarios where vertical and horizontal spaces are limited, such as tunnels, connecting passages, and inclined shafts, solving the industry pain point that the height of existing guide platforms encroaches on space and cannot be used inside tunnels.

[0071] Significantly improves construction efficiency and reduces construction period and cost: The posture adjustment does not require disassembly, reconstruction, or secondary pouring. The adjustment can be completed with one click through the linear drive mechanism. The adjustment process is extremely simple and time-saving. It reduces the input of consumables, labor, and machine shifts, avoids the indirect costs of construction delays, and reduces the overall construction cost by more than 40% compared with existing technologies.

[0072] Excellent structural mechanical properties and safe and stable operation: The symmetrical structure, independent dual-side drive, and double-link hinged sliding composite structure achieve uniform load distribution, eliminating stress concentration and unilateral overload problems; the sliding pair provides precise guidance without jamming, and the hinged transmission is reliable, capable of withstanding the heavy load of large-tonnage tunneling machines and construction impacts. The device has a long service life and a high safety factor.

[0073] Modular and universal structure, convenient processing and maintenance: The core connecting rod, slider, slide rail / slide rail and drive component are all modular structures, and the symmetrical components are universally designed, making processing, assembly and replacement easy; the sliding pair, drive component and other vulnerable parts can be maintained and replaced separately, and the maintenance cost is low; the two adjustment systems operate independently, and the fault diagnosis and repair are simple.

[0074] The adjustment mode is flexible and adaptable to diverse construction processes: the vertical and horizontal adjustment systems can operate independently or synchronously, supporting pure lifting, pure pitching, pure lateral movement, pure swaying and compound posture adjustment. The arrangement of drive components and the form of sliding pairs can be flexibly selected, which is suitable for both low-cost general construction scenarios and high-precision and high-protection special construction scenarios. The device's versatility and practicality are industry-leading.

[0075] It replaces traditional fixed guide platforms and single-dimensional adjustable guide platforms, and has technological iteration value: its comprehensive performance is superior to existing fixed posture guide platforms, height-adjustable guide platforms, and guide platforms that cannot be used in confined spaces. It can be used as a general-purpose equipment for starting / receiving guidance of tunnel boring machines, and promotes the upgrading of tunnel boring machine construction guide platform technology from fixed type to multi-degree-of-freedom adjustable type and confined space dedicated type.

[0101] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0102] A guide platform device for starting or receiving tunneling machines, such as Figure 1As shown, the system includes a guide bracket 2 and a guide base 3 connected by a linkage mechanism and a linear drive mechanism. The linear drive mechanism drives the linkage mechanism, thereby causing the guide bracket 2 to rise and fall or pitch relative to the guide base 3. In other words, the linkage mechanism and the linear drive mechanism constitute a pitch and lift mechanism 4. The extension and retraction of the linear drive mechanism can drive the linkage mechanism, which in turn uses the guide base 3 as a reaction force support to cause the guide bracket 2 to rise and fall or pitch as a whole.

[0103] At least one side of the guide platform base 3 is connected to a lateral reaction base 1 via a second linkage mechanism and a second linear drive mechanism.

[0124] This embodiment discloses a shield tunneling machine launching and receiving guide platform device with rapidly adjustable attitude, suitable for tunneling machine launching / receiving operations. It can quickly adjust the launching attitude in four degrees of freedom even in confined launching sites. Its specific structure and implementation process are as follows:

[0125] The device comprises a lateral reaction base 1, a guide bracket 2, a guide base 3, a pitching and lifting mechanism 4, and a left and right tilting and lateral movement mechanism 5. The lateral reaction base 1 is located at the bottom of the launching and receiving guide platform and is fixed on the launching site. The guide bracket 2 is located at the top of the launching and receiving guide platform. During launching, the tunnel boring machine (TBM) is placed on the inclined support plate 201 on the guide bracket 2. The launching and receiving guide platform device indirectly adjusts the launching and receiving attitudes of the TBM by adjusting the attitude of the guide bracket. The guide base 3 is placed flat on the launching site, and the area within the contact point between the site and the guide base 3 must be locally flat. To ensure the guide platform base 3 can slide horizontally on the field, the pitch and lifting mechanism 4 is arranged on both sides of the launching and receiving guide platform device. The extension and retraction of the hydraulic cylinders at both ends of the mechanism control the lifting and lowering of the two ends of the guide platform bracket 2, thereby realizing the pitch and lifting movements of the guide platform bracket 2. The left and right tilting and lateral movement mechanism 5 is arranged at the bottom of the launching and receiving guide platform device. The extension and retraction of the hydraulic cylinders at both ends of the mechanism control the lateral movement of the two ends of the guide platform base 3 on the launching field, and simultaneously drive the lateral movement of the two ends of the guide platform bracket 2 installed on the guide platform base 3, thereby realizing the left and right tilting and lateral movement of the guide platform bracket 2. The pitch and lifting mechanism 4 and the left and right tilting and lateral movement mechanism 5 operate independently and do not interfere with each other.

[0126] The following section explains in detail how the device achieves attitude adjustment movements with four degrees of freedom.

[0127] Lifting and lowering movements, such as Figure 7 As shown: In the pitch lifting mechanism 4, the first two hydraulic cylinders 403 extend simultaneously, and the second hinge point 202 on the guide bracket 2 moves upward as the hydraulic cylinders extend, driving the transmission rod 402 to rotate along the hinge point. The slider 401 slides towards the middle along the first slide groove 302. At this time, the guide bracket 2 moves away from the guide base 3. Conversely, the first hydraulic cylinder 403 retracts simultaneously, and the guide bracket 2 moves closer to the guide base 3.

[0128] Pitching motions such as Figure 8 As shown: In the pitch lifting mechanism 4, one end of cylinder 403 extends while the other end remains stationary. The hinge point 202 on the guide bracket 2, on the same side as the extended cylinder, moves upwards with the cylinder extension, simultaneously driving the transmission rod 402 to rotate along the hinge point. The slider 401 slides along the slide groove 302 towards the center. At this time, one end of the guide bracket 2 on the same side as the extended cylinder moves away from the reaction base 1. Although the other end of the guide bracket 2 is located a small distance away due to the movement of the connecting rod and cylinder on the same side, a height difference has been formed between the two ends of the launching and receiving guide, meaning the guide bracket 2 tilts to one side, achieving the pitch movement of the launching bracket 2. Conversely, it tilts to the other side.

[0129] Horizontal movement as Figure 9 As shown: the left and right lateral movement mechanism 5 has two hydraulic cylinders 503 extending simultaneously. The hinge point 303 on the guide platform base 3 extends away from the reaction base 1 along with the hydraulic cylinders, simultaneously driving the transmission rod 502 to rotate along the hinge point. The slider 501 slides towards the center along the slide groove 302. At this time, the guide platform base 3 overcomes friction and slides on the starting site. The platform base 3 and its guide platform bracket 2 move away from the reaction base 1, realizing the lateral movement of the starting bracket 2. Conversely, the hydraulic cylinders 502 retract simultaneously, and the guide platform bracket 2 moves closer to the reaction base 1.

[0130] The left and right head-shaking movements are like Figure 10 As shown: One end of the left and right lateral tilting mechanism 5 has a cylinder 503 extending out, while the other end of the cylinder 503 remains stationary. The hinge point 303 on the guide base 3, which is on the same side as the extended cylinder, moves away from the reaction base 1 as the cylinder extends out, simultaneously driving the transmission rod 502 to rotate along the hinge point. The slider 501 slides towards the center along the slide groove 102. At this time, one end of the guide base 3, which is on the same side as the extended cylinder, moves away from the reaction base 1. Although the other end of the guide base 3 is displaced by a certain distance due to the action of the connecting rod and the cylinder on the same side, the two ends of the starting and receiving guides form a displacement difference, that is, the guide bracket 2 tilts to one side, realizing the left and right tilting action of the starting bracket 2. Conversely, it tilts to the other side.

[0131] The above four actions, either individually or in combination, can achieve attitude adjustment of the four degrees of freedom of the transmitting and receiving guide.

[0132] Construction Example 1: Tunnel construction starting from the ground and descending, such as... Figure 11 As shown:

[0133] The front end of the equipment along the tunneling direction is called the head of the equipment. At the start, the starting receiving platform is fixed at the starting site, the shield is placed on the platform, the platform is controlled to adjust its posture to the head-down posture, and the shield follows the posture of the platform to start construction at an angle downward. When the entire tunnel is completed, the shield will start construction at an angle upward from the underground tunnel until the shield emerges from the surface. At this time, the platform fixed at the receiving site is controlled to adjust its posture to the upward posture to receive the shield.

[0134] Construction Example 2: Excavating a meandering passage towards the sidewall inside the tunnel, such as... Figure 12 As shown:

[0135] When a section of the tunnel collapses, a detour is excavated on the tunnel sidewall to avoid the collapsed section. At the start, the launching and receiving platform is fixed at the starting position of the tunnel. The shield is placed on the platform, and the platform's movement is controlled to adjust its attitude to a right (left) head-swinging posture. The shield follows the platform's posture and starts construction diagonally to the right (left). When the entire detour is completed, the shield enters the main tunnel diagonally to the left (right) from the detour. When the shield emerges from the detour, the platform fixed at the receiving site in the main tunnel is controlled to adjust its attitude to a left (right) head-swinging posture to receive the shield.

[0136] Compared with existing technologies, this launch and receiving guide platform device with rapid attitude adjustment solves the problem that existing guide platforms require reconstruction and fixation for attitude adjustment. While ensuring the attitude adjustment function, this solution improves the utilization rate of the launch site space through the rational layout of the mechanism components. It can be applied to the launch and receiving operations of tunnel boring machines in confined launch sites. Compared with the single attitude adjustment of existing launch guide platforms, this invention can realize rapid adjustment of the launch and receiving attitude of the tunnel boring machine with four degrees of freedom, covering all degrees of freedom required for launch and receiving attitude adjustment.
