Description

Technical Field

[0001] This invention relates to the field of engineering equipment technology, and more specifically, to a vehicle moving system and its working method, as well as a tunnel excavation system. Background Technology

[0002] During the tunnel excavation process, it is necessary to transport engineering vehicles into and out of the tunnel to meet the needs of tunnel excavation, such as clearing excavated soil. Therefore, it is necessary to excavate a starting shaft on the ground and set up a ground crane at the starting shaft to lift engineering vehicles and realize the purpose of engineering vehicles entering and exiting from the starting tunnel.

[0003] However, in tunnel excavation projects such as subway tunnels that need to be constructed in urban areas, in order to reduce the impact on ground traffic and the environment, the excavation size of the starting shaft is relatively small, and the ground opening should also be as compact as possible, resulting in very limited working space for ground cranes.

[0004] When engineering vehicles transport materials for tunnel excavation, they generally enter and exit in a single direction. When engineering vehicles are loading and unloading inside the tunnel, the ground crane needs to stop and wait. When engineering vehicles are waiting to be hoisted at the starting shaft, the ground crane can only hoist one engineering vehicle at a time. This results in low efficiency when engineering vehicles enter and exit the starting shaft, and the tunnel excavation equipment needs to stop and wait for a long time. The continuity of operation of tunnel excavation equipment and ground crane is low, which has a serious adverse impact on the construction efficiency of tunnel excavation. Summary of the Invention

[0005] The problem addressed by this invention is how to improve the construction efficiency of tunnel excavation when the space of the starting shaft is limited and the starting portal is narrow.

[0006] To address the above problems, in one aspect, the present invention provides a vehicle mobility system, comprising:

[0007] A vehicle moving guide rail assembly, comprising a first guide rail and a second guide rail, both the first guide rail and the second guide rail being arranged along a first direction, the first guide rail and the second guide rail being spaced apart along a second direction, the second guide rail being used to be sequentially distributed with the starting shaft along the first direction, the first guide rail and / or the second guide rail being connected to the tunnel excavation operation area, wherein the angle between the first direction and the second direction is greater than 0 degrees;

[0008] A vehicle transfer assembly, comprising a vehicle transfer platform for reciprocating along the second direction to dock with the first guide rail or the second guide rail.

[0009] Compared to existing technologies, the beneficial effects of the vehicle movement system of the present invention include: a vehicle moving guide rail assembly is formed by setting up a first guide rail and a second guide rail. At least one of the first and second guide rails can be connected to the tunnel excavation work area. Vehicles can move along the first or second guide rail to enter the tunnel excavation work area to participate in tunnel excavation operations. Vehicles that have completed their work or need to be moved out of the tunnel can also enter the first or second guide rail from the tunnel excavation work area to be moved out of the launching shaft. A vehicle moving assembly is set between the first and second guide rails. The vehicle moving platform in the vehicle moving assembly reciprocates between the first and second guide rails to dock with them. Through the first guide rail, the second guide rail, and the vehicle moving assembly, vehicles can move between the three, moving in and out of the launching shaft, satisfying the needs of vehicles entering and exiting the tunnel excavation work area and moving between the tunnel and the launching shaft. A stable vehicle movement route is formed, ensuring the stable cyclical movement of vehicles. During this cyclical movement, both the tunnel boring equipment and the ground crane operate without interruption, reducing time wasted due to downtime and ensuring the continuity of their operations. This significantly improves the efficiency of tunnel boring operations, shortens the downtime of the ground crane, and avoids the traffic and environmental impacts caused by prolonged crane downtime. Furthermore, by connecting at least one of the first and second guide rails to the tunnel boring area, one of these rails can be used as a spare vehicle storage area. This allows the ground crane to lift all vehicles into the launching shaft at once for departure, and the vehicles can then enter the tunnel in the required order on the other guide rail via the movement of the vehicle transfer platform, participating in the tunnel boring process.

[0010] Optionally, the vehicle moving assembly further includes a vehicle moving guide rail and a locking device. The vehicle moving guide rail is disposed on the vehicle moving platform along the first direction and is used to support the vehicle. The locking device is located at the end of the vehicle moving guide rail, and the vehicle moving guide rail is used to be detachably connected to the first guide rail or the second guide rail via the locking device.

[0011] Optionally, the vehicle moving platform includes a support plate, a guide rail, and moving wheels. The guide rail is arranged along the second direction, the moving wheels are located on the lower end face of the support plate and are used to be placed on the guide rail, and the support plate is used to support the vehicle.

[0012] Optionally, the vehicle movement system further includes a parallel guide rail. In the direction toward the tunnel excavation work area, the end of the first guide rail away from the starting shaft and the end of the second guide rail away from the starting shaft approach each other and are connected to form the parallel guide rail, which is connected to the tunnel excavation work area.

[0013] Optionally, the moving assembly further includes a transition moving platform located on the side of the second guide rail away from the launching well. The transition moving platform is used to reciprocate along the second direction to dock with the first guide rail or the second guide rail.

[0014] Optionally, the vehicle transfer guide rail assembly further includes a third guide rail, which is arranged along the first direction and located on the side of the second guide rail opposite to the first guide rail, and the vehicle transfer platform is used to dock with the third guide rail.

[0015] Optionally, the vehicle moving system further includes a lifting assembly, which includes a support platform, a support frame, and a lifting platform. The support platform is located on one side of the starting manhole and is distributed sequentially with the vehicle moving platform along the second direction. The support frame is disposed on the support platform, and the lifting platform is slidably mounted on the support frame. The lifting platform is used to carry the vehicle and move up and down. When the lifting platform moves down, it is used to dock with the first guide rail or the third guide rail. When the lifting platform moves up, a space is formed below the lifting platform to accommodate the vehicle.

[0016] Optionally, the lifting platform includes a lifting plate, a lifting guide rail, and a stabilizing device. The lifting plate is slidably mounted on the support frame. The lifting guide rail is disposed on the lifting plate and arranged along the first direction. The stabilizing device is disposed on the lifting plate and located on one side of the lifting guide rail. The lifting guide rail is used to support the vehicle and is detachably connected to the vehicle's wheels through the stabilizing device.

[0017] On the other hand, the present invention also provides a method for operating a vehicle mobility system, applied to the vehicle mobility system described above, comprising the following steps:

[0018] When the vehicle of the tunnel boring system enters the starting shaft, the drive platform moves to the bottom of the starting shaft to carry the vehicle.

[0019] The vehicle transfer platform is driven to dock with the second guide rail so that the vehicle can enter the second guide rail and move to the tunnel excavation work area; or, the vehicle transfer platform is driven to move and dock with the first guide rail so that the vehicle can enter the first guide rail for storage and standby.

[0020] When the vehicle enters the first guide rail from the tunnel excavation work area or when the spare vehicle needs to enter the second guide rail, the vehicle transfer platform is driven to move and dock with the first guide rail to receive the vehicle.

[0021] The vehicle moving platform is driven to move and dock with the second guide rail, so that the vehicle can be moved out of the starting shaft or into the second guide rail and moved to the tunnel excavation operation area.

[0022] Compared to the prior art, the beneficial effects of the working method of the vehicle movement system of the present invention are the same as those of the vehicle movement system described above, and will not be repeated here.

[0023] In another aspect, the present invention also provides a tunnel boring system, including a ground crane, a vehicle, and a vehicle movement system as described above.

Detailed Implementation

[0033] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0034] It should be noted that in the XYZ coordinate system provided herein, the positive direction of the X-axis represents the right, and the negative direction of the X-axis represents the left; the positive direction of the Y-axis represents the rear, and the negative direction of the Y-axis represents the front; the positive direction of the Z-axis represents the top, and the negative direction of the Z-axis represents the bottom. Furthermore, it should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein.

[0035] On one hand, one embodiment of the present invention provides a vehicle moving system, including: a vehicle moving guide rail group 1, the vehicle moving guide rail group 1 including a first guide rail 11 and a second guide rail 12, the first guide rail 11 and the second guide rail 12 are both arranged along a first direction, the first guide rail 11 and the second guide rail 12 are spaced apart along a second direction, the second guide rail 12 is used to be sequentially distributed with the starting shaft 4 along the first direction, the first guide rail 11 and / or the second guide rail 12 are connected to the tunnel excavation operation area, wherein the angle between the first direction and the second direction is greater than 0 degrees; a vehicle moving assembly 2, the vehicle moving assembly 2 including a vehicle moving platform 21, the vehicle moving platform 21 is used to reciprocate along the second direction to dock with the first guide rail 11 or the second guide rail 12.

[0036] In this embodiment, as Figures 1 to 6 As shown, the angle between the first direction and the second direction is 90 degrees. The first direction is the Y-axis direction, and the second direction is the X-axis direction.

[0037] like Figures 1 to 6As shown, in this embodiment, a first guide rail 11 and a second guide rail 12 are arranged to form a moving guide rail group 1. Both the first guide rail 11 and the second guide rail 12 are arranged along a first direction and spaced apart along a second direction. The second guide rail 12 and the launching shaft 4 are sequentially distributed along the first direction. At least one of the first guide rail 11 and the second guide rail 12 can be connected to the tunnel excavation work area. Thus, the vehicle 3 can move along the first guide rail 11 or the second guide rail 12 to enter the tunnel excavation work area and participate in tunnel excavation operations. The vehicle 3 can also be moved out of the tunnel after completing its work. The tunnel excavation work area enters the first guide rail 11 or the second guide rail 12 in preparation for removal from the starting shaft 4. A vehicle transfer assembly 2 is set between the first guide rail 11 and the second guide rail 12. The vehicle transfer assembly 2 includes a vehicle transfer platform 21, which can move back and forth in a second direction to connect with the first guide rail 11 and the second guide rail 12. In this way, through the first guide rail 11, the second guide rail 12 and the vehicle transfer assembly 2, a stable cyclic movement line for the vehicle 3 is formed between the tunnel and the starting shaft 4, ensuring the stable cyclic movement of the vehicle 3 and improving the efficiency of the tunnel excavation operation.

[0038] Meanwhile, it should be noted that in this embodiment, a first driving device and a control device electrically connected to the first driving device are provided. The first driving device is driven to the vehicle moving platform 21. In this way, the control device can control the moving position and direction of the vehicle moving platform 21 through the first driving device, thereby adjusting the position of the vehicle moving platform 21 according to different working conditions. In coordination with the ground crane, the vehicle 3 can move stably and cyclically between the starting shaft 4 and the tunnel. In the case of limited space in the starting shaft 4 and narrow starting opening, the efficiency of the engineering vehicle 3 entering the starting shaft 4 is improved, the construction efficiency of tunnel excavation is improved, the docking time of the ground crane is reduced, and the adverse impact on ground traffic is reduced.

[0039] It should be noted that in this embodiment, the first driving device is a chain driving device. In other embodiments of the present invention, other driving devices such as gear mechanisms or winches may also be used.

[0040] Specifically, regarding the situation where the ground crane at the starting shaft 4 lifts vehicles 3 into the starting shaft 4, there are generally two types. One is during the tunnel excavation starting and waiting stage, when vehicles 3 such as muck trucks, mud trucks, and segment trolleys are lifted into the starting shaft 4. The other is during the stage when the muck trucks and mud trucks are transporting tunneling materials, when fully loaded transport vehicles need to be lifted out of the starting shaft 4 for unloading, and empty transport vehicles need to be lifted into the starting shaft 4 to continue material transportation.

[0041] In the first scenario, in this embodiment, when multiple types of vehicles 3 need to be hoisted to the tunnel for departure, the vehicle moving platform 21 can be connected to the second guide rail 12. A ground crane can then hoist different vehicles 3 onto the vehicle moving platform 21. By moving the vehicle moving platform 21 along the second direction, different vehicles 3 can be moved to the first guide rail 11 for storage and to the second guide rail 12 for departure. This allows all vehicles 3 to be hoisted into the starting shaft 4 at once. The correct sequence for all vehicles 3 during tunnel excavation can be determined by the reciprocating movement of the vehicle moving platform 21 along the second direction between the first guide rail 11 and the second guide rail 12. This allows the vehicles 3 to enter the tunnel in the required order on the second guide rail 12 and participate in the tunnel excavation process.

[0042] Regarding the second scenario, in the existing technology, during the transportation and unloading of excavation materials such as slag or mud, all slag or mud trucks need to be loaded into the tunnel excavation work area inside the tunnel. Then, a frequency converter locomotive drives all the slag or mud trucks to move along the guide rail to the starting shaft 4. Due to the small working space of the ground crane, it needs to be lifted one by one by the ground crane, unloaded on the ground, and then lifted into the starting shaft 4. During this process, the tunnel excavation equipment inside the tunnel is in a stopped state. After all the slag or mud trucks have been unloaded, the frequency converter locomotive drives them to the tunnel excavation work area for loading. During the loading process, the ground crane is in a stopped state again, thus making it impossible to form a continuous cycle of operation, resulting in poor equipment operation continuity and low operation efficiency.

[0043] In this embodiment, two guide rails, a first guide rail 11 and a second guide rail 12, are installed inside the tunnel. Both the first guide rail 11 and the second guide rail 12 are connected to the tunnel excavation work area. Vehicles 3 are transported between the first guide rail 11 and the second guide rail 12 via the reciprocating movement of a vehicle transfer platform 21. Thus, during the loading and unloading of excavated materials, multiple vehicles 3 can form a stable, cyclical flow of vehicles between the first guide rail 11 and the second guide rail 12. Specifically, after loading excavated materials in the tunnel excavation work area, a vehicle 3 can enter the first guide rail 11 to proceed to the starting shaft 4. The first guide rail 11 is moved via the vehicle transfer platform 21 to below the ground crane work area of ​​the starting shaft 4, where it is lifted and unloaded by the ground crane and then hoisted back into place, entering the second guide rail 12 to proceed to the tunnel excavation work area for loading. During this process, other vehicles... 3. The vehicle 3 may be loaded in the tunnel excavation area, or proceed to the starting shaft 4 on the first guide rail 11, or wait at the end of the first guide rail 11 for the moving platform 21 to carry it to the area below the ground crane operation area, or proceed to the tunnel excavation area on the second guide rail 12. This creates a stable circular flow of vehicles on the ground, starting shaft 4, moving platform 21, second guide rail 12, tunnel excavation area, and first guide rail 11. During the movement of vehicle 3, both the tunnel excavation equipment and the ground crane operate without stopping, reducing the time wasted due to downtime of the tunnel excavation equipment and the ground crane. At the same time, it ensures the continuity of the operation of the tunnel excavation equipment and the ground crane, greatly improving the construction efficiency of tunnel excavation, shortening the downtime of the ground crane, and avoiding the traffic and environmental impact caused by the long-term downtime of the ground crane.

[0044] It should be noted that, in this embodiment, as Figures 1 to 5 As shown, the first guide rail 11 consists of two parts, respectively set on both sides of the starting shaft 4 along the Y-axis. The second guide rail 12 also consists of two parts, respectively set on both sides of the starting shaft 4 along the Y-axis. When the moving platform 21 moves along the X-axis, the two ends of the moving platform 21 along the Y-axis can respectively connect with the two first guide rails 11 or the two second guide rails 12. In this way, when the frequency converter locomotive drives the vehicle 3 to move along one side of the first guide rail 11 or the second guide rail 12, the frequency converter locomotive can pass through the moving platform 21 and enter the opposite side of the first guide rail 11 or the second guide rail 12, so that the vehicle 3 can stop on the moving platform 21. By disconnecting the vehicle 3 from other vehicles, the moving platform 21 can move the vehicle 3 along the X-axis. Of course, when all the vehicles 3 are hoisted into the starting shaft 4 to wait for departure, some vehicles 3 can also be moved to the first guide rail 11 or the second guide rail 12 away from the tunnel excavation operation area for standby storage.

[0045] It should be noted that, in this embodiment, for situations where the tunnel excavation work area is relatively large, both the first guide rail 11 and the second guide rail 12 can be configured to connect to the tunnel excavation work area, thereby forming two guide rails with opposite vehicle movement directions between the tunnel excavation work area and the launching shaft, effectively improving the efficiency of tunnel excavation operations. Correspondingly, in other embodiments of the present invention, for situations where the tunnel excavation work area is relatively small, the second guide rail 12 can be configured to connect to the tunnel excavation work area, while the first guide rail 11 is only arranged parallel to the second guide rail 12 in the launching area. In this way, the vehicle moving assembly 2 not only meets the need for vehicles to enter the tunnel excavation work area through the second guide rail 12 for operation, achieving the purpose of operation in narrow areas, but also allows for temporary vehicle storage through the first guide rail 11, satisfying the need for all vehicles to start and move cyclically at once during tunnel excavation operations. Of course, in other embodiments of the present invention, the first guide rail 11 can also be configured to connect to the tunnel excavation work area, while the second guide rail 12 is only arranged parallel to the first guide rail 11 in the launching area.

[0046] Optionally, the vehicle transfer assembly 2 also includes a vehicle transfer guide rail 22 and a locking device 23. The vehicle transfer guide rail 22 is disposed on the vehicle transfer platform 21 along a first direction and is used to support the vehicle 3. The locking device 23 is located at the end of the vehicle transfer guide rail 22. The vehicle transfer guide rail 22 is used to be detachably connected to the first guide rail 11 or the second guide rail 12 through the locking device 23.

[0047] In this embodiment, as Figures 1 to 5 As shown, a vehicle transfer guide rail 22 is provided on the vehicle transfer platform 21 along the first direction, i.e., the Y-axis direction. When the vehicle transfer platform 21 moves and docks with the first guide rail 11 or the second guide rail 12, the vehicle transfer guide rail 22 can dock with the first guide rail 11 or the second guide rail 12, which facilitates the stable movement of the vehicle 3 between the vehicle transfer guide rail 22 and the first guide rail 11 or between the vehicle transfer guide rail 22 and the second guide rail 12. On one side of the end of the vehicle transfer guide rail 22, a locking device 23 is also provided. After the vehicle transfer guide rail 22 docks with the first guide rail 11 or the second guide rail 12, the locking device 23 can lock it, realizing the connection between the vehicle transfer guide rail 22 and the first guide rail 11 or the vehicle transfer guide rail 22 and the second guide rail 12, ensuring the stable movement of the vehicle 3. When the vehicle transfer platform 21 needs to move, the locking device 23 can be released, realizing the separation of the vehicle transfer guide rail 22 and the first guide rail 11 or the vehicle transfer guide rail 22 and the second guide rail 12.

[0048] It should be noted that, in this embodiment, the metallic properties of the moving guide rail 22, the first guide rail 11, and the second guide rail 12 can be utilized to set up an electromagnetic valve as a locking device 23. The connection and separation of the moving guide rail 22 and the first guide rail 11, or the connection and separation of the moving guide rail 22 and the second guide rail 12, can be achieved by switching the current on and off. Of course, in other embodiments of the present invention, other structures such as buckles or pneumatic clamping devices can also be set as the locking device 23.

[0049] Optionally, the vehicle moving platform 21 includes a support plate 211, a guide rail 212, and moving wheels 213. The guide rail 212 is arranged along the second direction, and the moving wheels 213 are located on the lower end face of the support plate 211 and are used to be placed on the guide rail 212. The support plate 211 is used to support the vehicle 3.

[0050] In this embodiment, as Figures 1 to 5 As shown, a vehicle moving platform 21 is composed of a support plate 211, a guide rail 212, and moving wheels 213. The guide rail 212 is set along the second direction, i.e., the X-axis direction. The moving wheels 213 are set on the lower end surface of the support plate 211 and placed on the guide rail 212. The support plate 211 can carry the vehicle 3. In this way, when it is necessary to move the support plate 211, it is only necessary to drive the moving wheels 213 to rotate in the forward or reverse direction to realize the reciprocating movement of the support plate 211 along the X-axis direction. The guide rail 212 guides the movement of the moving wheels 213 and ensures the stability of the reciprocating movement of the support plate 211 along the X-axis.

[0051] It should be noted that in this embodiment, the movable wheel 213 is driven to be connected to the first driving device to ensure the stable rotation of the movable wheel 213. The height of the guide rail 212 is lower than the height of the first guide rail 11 and the second guide rail 12. The height of the first guide rail 11 and the second guide rail 12 are the same, so that when the movable wheel 213 and the support plate 211 are placed on the guide rail 212, the vehicle 3 can smoothly enter the support plate 211 from the first guide rail 11 or the second guide rail 12.

[0052] Optionally, the vehicle movement system also includes parallel guide rails. In the direction toward the tunnel excavation work area, the end of the first guide rail 11 away from the starting shaft 4 and the end of the second guide rail 12 away from the starting shaft 4 approach each other and are connected to form parallel guide rails, which are connected to the tunnel excavation work area.

[0053] In this embodiment, a parallel guide rail is also provided. In the direction towards the tunnel excavation operation area, the end of the first guide rail 11 away from the starting shaft 4 can approach the end of the second guide rail 12 away from the starting shaft 4 and eventually connect with each other to form a parallel guide rail. The parallel guide rail can be connected to the tunnel excavation operation area. In this way, the vehicle 3 can enter the tunnel excavation operation area for loading along the second guide rail 12 and the parallel guide rail, and then enter the first guide rail 11 along the parallel guide rail to go to the starting shaft 4, thereby forming a stable and cyclical operation flow.

[0054] Optionally, the moving assembly 2 also includes a transition moving platform located on the side of the second guide rail 12 away from the starting well 4. The transition moving platform is used to move back and forth along the second direction to dock with the first guide rail 11 or the second guide rail 12.

[0055] In this embodiment, a transition platform is also provided. The transition platform is located on the side of the second guide rail 12 away from the starting shaft 4, that is, on the side facing the tunnel excavation operation area. The transition platform can also move along the X-axis and dock with the first guide rail 11 or the second guide rail 12. In this way, after the vehicle 3 enters the tunnel excavation operation area from the second guide rail 12 and is loaded, it enters the transition platform from the second guide rail 12. The transition platform moves and docks with the first guide rail 11, so that the vehicle 3 enters the first guide rail 11 and goes to the starting shaft 4, thereby forming a stable and cyclical operation flow.

[0056] It should be noted that in this embodiment, a second driving device is provided to drive the transition platform to move stably. The second driving device is a chain driving device. In other embodiments of the present invention, other driving devices such as gear mechanisms or winches may also be used.

[0057] Optionally, the vehicle transfer guide rail assembly 1 also includes a third guide rail 13, which is arranged along the first direction and located on the side of the second guide rail 12 away from the first guide rail 11. The vehicle transfer platform 21 is used to dock with the third guide rail 13.

[0058] In this embodiment, as Figures 1 to 5 As shown, a third guide rail 13 along the Y-axis is also provided on the side of the second guide rail 12 away from the first guide rail 11. When the vehicle moving platform 21 moves back and forth along the X-axis, it can dock with the third guide rail 13. In this way, when all vehicles 3 are hoisted to the starting shaft 4 by the ground crane for waiting and departure, the vehicle moving platform 21 can move along the X-axis and dock with the third guide rail 13 after carrying the vehicle 3. The vehicle 3 can be stored in the third guide rail 13 from the vehicle moving platform 21 for later use. When it is necessary to move it out, it can enter the second guide rail 12 to participate in the tunnel excavation operation through the back and forth movement of the vehicle moving platform 21. This further ensures the order and smoothness of the movement of the vehicle 3 in the tunnel and avoids the problem that when there are many vehicles 3, they cannot be completely placed in the tunnel at one time.

[0059] Optionally, the vehicle moving system also includes a lifting assembly 5, which includes a support platform 51, a support frame 52, and a lifting platform 53. The support platform 51 is located on one side of the starting well 4 and is distributed sequentially with the vehicle moving platform 21 along the second direction. The support frame 52 is mounted on the support platform 51, and the lifting platform 53 is slidably mounted on the support frame 52. The lifting platform 53 carries the vehicle 3 and moves up and down. When the lifting platform 53 moves down, it is used to dock with the first guide rail 11 or the third guide rail 13. When the lifting platform 53 moves up, a space is formed below the lifting platform 53 to accommodate the vehicle 3.

[0060] It should be noted that, in this embodiment, as Figure 6 As shown, the lifting platform 53 is slidably mounted on the support frame 52 along the Z-axis direction.

[0061] In this embodiment, as Figures 1 to 6 As shown, a lifting assembly 5 is composed of a support platform 51, a support frame 52, and a lifting platform 53. The support platform 51 is located on one side of the starting manhole 4 and can be sequentially distributed with the moving platform 21 along the X-axis. The support frame 52 is mounted vertically on the support platform 51 along the Z-axis. The lifting platform 53 is slidably mounted on the support frame 52, allowing it to move up and down along the support frame 52. When the lifting platform 53 moves down, it can engage with the first guide rail 11 or the third guide rail 13. Thus, when the vehicle 3 passes through the moving platform 21 and enters the first guide rail 11 or the third guide rail 13 for storage, the lifting platform 53 can be moved down to engage with the first guide rail 11 or the third guide rail 13, allowing the vehicle 3 to enter the lifting platform 53. Then, the lifting platform 53 can be moved up again. This creates two layers of space at the first guide rail 11 or the third guide rail 13, which can be used to store vehicles 3, increasing the space available for placing vehicles 3 in the tunnel. After the lifting platform 53 moves upward, a space can be formed below the lifting platform 53 to accommodate vehicles 3, making it easier for the vehicle moving platform 21 to carry vehicles 3 and move along the X-axis, and dock with the first guide rail 11 or the third guide rail 13, so that vehicles 3 can enter the first guide rail 11 or the third guide rail 13. When vehicles 3 need to be moved out for use, the lifting platform 53 is simply moved downward, so that vehicles 3 can enter the first guide rail 11 or the third guide rail 13, and then enter the required guide rail through the vehicle moving platform 21. This further ensures the order and smoothness of the movement of vehicles 3 in the tunnel, and further avoids the problem that when there are many vehicles 3, they cannot be completely placed in the tunnel at once.

[0062] It should be noted that in this embodiment, a third driving device is provided to drive the lifting platform 53 to move up and down. The third driving device is a lifting cylinder. In other embodiments of the present invention, other driving devices such as chain drive devices, gear mechanisms or winches can also be used.

[0063] Optionally, the lifting platform 53 includes a lifting plate 531, a lifting guide rail 532, and a stabilizing device 533. The lifting plate 531 is slidably mounted on the support frame 52. The lifting guide rail 532 is disposed on the lifting plate 531 and is arranged along a first direction. The stabilizing device 533 is disposed on the lifting plate 531 and is located on one side of the lifting guide rail 532. The lifting guide rail 532 is used to support the vehicle 3 and is detachably connected to the wheels of the vehicle 3 through the stabilizing device 533.

[0064] In this embodiment, as Figure 6 As shown, a lifting platform 53 is composed of a lifting plate 531, a lifting guide rail 532, and a stabilizing device 533. The lifting plate 531 is slidably mounted on the support frame 52, while the lifting guide rail 532 is mounted on the lifting plate 531 and is arranged along the Y-axis. Thus, when the lifting platform 53 moves down to align with the first guide rail 11 or the third guide rail 13, the lifting guide rail 532 can connect accordingly with the first guide rail 11 or the third guide rail 13, facilitating the entry and exit of the vehicle 3 from the lifting platform 53. A stabilizing device 533 is also provided on 531. The stabilizing device 533 is located on one side of the lifting guide rail 532. When the vehicle 3 enters the lifting guide rail 532, the stabilizing device 533 can lock, so that the wheels of the vehicle 3 are connected to the lifting guide rail 532, ensuring the stability of the vehicle 3 on the lifting platform 53. When the vehicle 3 needs to be moved out of the lifting platform 53, the stabilizing device 533 can be released, so that the wheels of the vehicle 3 are separated from the lifting guide rail 532.

[0065] It should be noted that the metallic properties of the lifting guide rail 532 and the wheels of the vehicle 3 can be utilized to install an electromagnetic valve as a stabilizing device 533, which connects and separates the lifting guide rail 532 and the wheels of the vehicle 3 by switching the current on and off. Of course, in other embodiments of the present invention, other structures such as buckles or pneumatic clamping devices can also be used as stabilizing devices 533.

[0066] On the other hand, one embodiment of the present invention provides a method for operating a vehicle mobility system, applied to the aforementioned vehicle mobility system, comprising the following steps:

[0067] When the vehicle 3 of the tunnel excavation system enters the starting shaft 4, the drive platform 21 moves to the bottom of the starting shaft 4 to carry the vehicle 3.

[0068] The vehicle moving platform 21 is driven to dock with the second guide rail 12 so that the vehicle 3 can enter the second guide rail 12 and move to the tunnel excavation work area; or, the vehicle moving platform 21 is driven to move and dock with the first guide rail 11 so that the vehicle 3 can enter the first guide rail 11 for storage and standby.

[0069] When vehicle 3 enters the first guide rail 11 from the tunnel excavation work area or when the spare vehicle 3 needs to enter the second guide rail 12, the vehicle transfer platform 21 is driven to move and dock with the first guide rail 11 to receive vehicle 3.

[0070] The vehicle transfer platform 21 is driven to move and dock with the second guide rail 12, so that the vehicle 3 can be moved out of the starting shaft 4 or into the second guide rail 12 and moved to the tunnel excavation operation area.

[0071] like Figures 1 to 6 As shown, the technical effects of the working method of the vehicle movement system in this embodiment are similar to those of the vehicle movement system described above, and will not be repeated here.

[0072] In another aspect, one embodiment of the present invention provides a tunnel boring system, including a ground crane, a vehicle 3, and the aforementioned vehicle moving system.

[0073] like Figures 1 to 6 As shown, the technical effect of the tunnel excavation system in this embodiment is similar to that of the vehicle movement system described above, and will not be repeated here.

[0074] While the disclosure is as stated above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this invention.
