Description

Technical Field

[0001] This invention belongs to the field of shield tunneling technology and relates to a battery-powered vehicle safety command signal system for simultaneous shield tunneling and connecting passage. Background Technology

[0002] In recent years, with the rapid development of urban rail transit, shield tunneling operations have faced challenges due to complex geological conditions, tight schedules, and the critical nature of shield tunneling. Therefore, it is crucial to rationally control the overall project schedule and plan for the simultaneous implementation of connecting passages and shield tunneling (with shield tunneling as the primary focus and connecting passage construction as a secondary measure) to reduce construction costs. However, the simultaneous construction of connecting passages and shield tunneling necessitates temporary occupation of the main tunnel. Before the main tunnel is completed, this occupation will inevitably affect its construction. Furthermore, during the simultaneous construction of shield tunneling and connecting passages, the passage of battery-powered vehicles excavating slag and transporting materials through the connecting passage construction area poses a risk of vehicle accidents and falling debris to workers. Untimely clearing of excavated slag and rocks from the connecting passage, and the falling rocks generated during the excavation of the connecting passage face by hydraulic breakers, can easily lead to derailment, overturning, and damage of battery-powered vehicles, as well as injuries to workers.

[0003] To ensure the safety of simultaneous tunneling and connecting tunnel construction, the traditional method is to use an audible and visual alarm signal control system. Before the electric vehicle reaches the construction point of the connecting tunnel, it is detected by the position sensor and an audible and visual warning is issued at the work site to remind the workers to pay attention to safety. However, this method can only serve as a warning and is easily affected by noise interference from surrounding machinery and equipment (excavators, water drills, and other construction equipment), so it cannot provide a stable warning effect. In addition, the installation is complicated and costly, which is insufficient to cope with the safety risks when the connecting tunnel and tunneling are carried out simultaneously.

[0004] Meanwhile, signal warning systems are widely used in tunnel construction both domestically and internationally. However, the application of command signal control with dedicated personnel and signal linkage is very rare. The main reason is that the risk of simultaneous construction of shield tunneling and connecting passages is high, so this method is generally not adopted for construction operations. On the other hand, the risk level of single tunnel construction is low, and there is no need to adopt a safety command signal system for dedicated personnel to control and direct. Therefore, ordinary sound and light signal alarm systems are generally used to direct transport vehicles in the tunnel. Summary of the Invention

[0005] The purpose of this invention is to provide a command signal control system that enables simultaneous construction of tunnel boring machines and connecting passages, provides signal command and control for battery-powered vehicles and construction crews, reduces the safety risks of cross-operations on site, and ensures the safe operation of horizontal transportation.

[0006] To achieve the above objectives, the present invention provides the following technical solution: including a first track and a second track laid inside a tunnel, and further comprising:

[0007] An annular groove is created in the section of track between the first and second tracks;

[0008] A rotating disk is rotatably connected within an annular groove, with its top extending upwards.

[0009] The third track is fixedly connected to the top of the rotating disk. Its two ends are respectively connected to the ends of the first track and the second track that are close to each other, forming a complete transport track. Both ends of the third track have an arc surface 1 set with the rotating disk as the center. The ends of the first track and the second track that are close to each other have an arc surface 2 that is connected to the arc surface 1 on the third track. When the rotating disk rotates, it can drive the third track to rotate and can be connected to the first track and the second track in a reverse-type manner.

[0010] The drive mechanism, located in the annular groove, is used to drive the rotating disk to rotate, thereby enabling the interchange of the two ends of the third track.

[0011] The first vertical pole is fixedly connected to the top edge of the rotating disk, and a signal light is fixedly installed at the top of the first vertical pole to indicate the passage of electric vehicles.

[0012] The second vertical pole is symmetrically arranged with the first vertical pole and is fixedly connected to the other side edge of the top of the rotating disk. The third track is located between the first vertical pole and the second vertical pole. An alarm is fixedly installed at the top of the second vertical pole to warn electric vehicles that are not passing through normally.

[0013] The warning mechanism, located on a rotating disc, works in conjunction with the wheels of the electric vehicle to automatically trigger the alarm.

[0014] Furthermore, the driving mechanism includes a servo motor fixedly connected to the bottom wall of the annular groove, a drive gear fixedly sleeved on the output shaft of the servo motor, a rotating column rotatably connected to the bottom wall of the annular groove, and the top end of the rotating column fixedly connected to the bottom of the rotating disk, and a driven gear meshing with the drive gear fixedly sleeved on the outer wall of the rotating column.

[0015] Furthermore, a support ring is fixedly connected to the inner wall of the annular groove, and the rotating disk is rotatably connected to the top of the support ring.

[0016] Furthermore, the warning mechanism includes an L-shaped block fixedly connected to one side of the top of the rotating disk. The L-shaped block is located inside the third track and is lower than the top surface of the third track. The top of the L-shaped block is provided with multiple sets of squeezing components that are used in conjunction with the wheels of the electric vehicle, and the squeezing components are used in conjunction with the alarm.

[0017] Furthermore, the extrusion assembly includes a mounting groove formed on the top of the L-shaped block. A first sliding plate is slidably connected inside the mounting groove. A first spring is fixedly connected to each of the four bottom corners of the first sliding plate, and the bottom end of the first spring is fixedly connected to the bottom wall of the mounting groove. Two fixing blocks are symmetrically fixedly connected to the top of the first sliding plate. The two fixing blocks are rotatably connected to the same rotating shaft. A pressure plate is fixedly sleeved on the outer wall of the rotating shaft. The pressure plate is inclined, with one end extending upward out of the mounting groove and the other end located in the mounting groove and in contact with the top of the first sliding plate. A limiting component is provided on the top of the first sliding plate for limiting one side of the bottom end of the pressure plate.

[0018] Furthermore, a pressure rod is fixedly connected to the bottom of the first slide plate, and an elastic switch located directly below the pressure rod and used in conjunction with the pressure rod is fixedly installed on the bottom wall of the mounting groove, and the elastic switch is electrically connected to the alarm.

[0019] Furthermore, a fixing sleeve is fixedly connected to one side of the bottom wall of the mounting groove. The top end of the fixing sleeve slides through the top of the first sliding plate and extends upward. A top rod slides through the top end of the fixing sleeve. The top end of the top rod abuts against the bottom side of the high end of the pressure plate. The bottom end of the top rod is fixedly connected to the same second spring between it and the bottom wall of the fixing sleeve.

[0020] Furthermore, the limiting component includes a slider slidably connected to one side of the top of the first slide plate, a limiting block fixedly connected to one side of the slider and used in conjunction with one side of the bottom of the pressure plate, the side of the slider away from the limiting block contacting the inner wall of one side of the mounting groove, and the interior of the L-shaped block is provided with multiple sets of pushing components that cooperate with the corresponding limiting components.

[0021] Furthermore, the pushing component includes a mounting cavity located inside the L-shaped block and on one side of the mounting groove. A second sliding plate is slidably connected inside the mounting cavity. Multiple third springs are fixedly connected between the top of the second sliding plate and the top wall of the mounting cavity. A pushing plate is slidably connected through the top of the top wall of the mounting cavity near the mounting groove. One side of the pushing plate extends into the mounting groove and is symmetrically fixedly connected to two convex sliders. Two convex grooves are symmetrically opened on the side of the sliders away from the limiting block and are slidably connected to the corresponding convex sliders. An upper connecting seat is fixedly connected to the bottom of the pushing plate, and a lower connecting seat is fixedly connected to the top of the second sliding plate. The same rotating plate is rotatably connected between the upper and lower connecting seats. A third vertical rod is fixedly connected to the bottom of the second sliding plate. The bottom end of the third vertical rod slides through the bottom of the L-shaped block and the rotating disk and extends downward into the annular groove. A trapezoidal plate that cooperates with the third vertical rod is fixedly connected to one side of the bottom wall of the annular groove.

[0022] Furthermore, there are two signal lights, which are symmetrically arranged at the top of the first vertical pole, one in front of the other, and the two signal lights emit different colors of light.

[0023] The beneficial effects of this invention are as follows:

[0024] 1. The shield tunneling and connecting passage simultaneous implementation of battery-powered vehicle safety command signal system disclosed in this invention effectively reminds and warns relevant workers by installing red and yellow signal lights and corresponding warning signs beside the track, providing safe conditions for cross-operation construction; when the track is occupied during the construction of the connecting passage, pressing the red signal light start button will turn the signal light red, reminding the battery-powered vehicle driver not to enter the construction area of ​​the connecting passage; when the construction of the connecting passage is completed or the battery-powered vehicle needs to pass in time, after communicating with the command signal personnel and waiting for the construction area of ​​the connecting passage to meet the requirements for battery-powered vehicle passage, pressing the yellow signal start button will adjust the signal light to yellow, and the battery-powered vehicle will slowly pass through the area, ensuring the safety of personnel and vehicles in cross-operation.

[0025] 2. The shield tunneling and connecting passage synchronous implementation of the battery-powered vehicle safety command signal system disclosed in this invention allows the battery-powered vehicle to enter when the tunnel conditions are not suitable. In this case, the person in charge starts the servo motor to rotate the turntable, reversing the two ends of the third track and reconnecting it with the first and second tracks. Simultaneously, the signal light changes from yellow to red, indicating that passage is prohibited. At this time, the pressure plate is in the reverse position, and the third vertical rod abuts against the top of the trapezoidal plate, pushing the third vertical rod upwards. This causes the limiting block to move to the top of the bottom side of the pressure plate and abut against it, thus achieving the abutment and limitation of the pressure plate. The battery-powered vehicle can still pass normally, but during passage, the wheels will press the pressure plate downwards, but the pressure plate will not rotate. Simultaneously, the first sliding plate will slide down, touching and squeezing the elastic switch, activating the alarm. This warns the driver of the passing battery-powered vehicle that it cannot enter, thus preventing accidental entry when the driver is not paying attention. The alarm can also warn the person in charge on site, improving construction safety within the tunnel.

[0026] The electric vehicle safety command signal system for simultaneous shield tunneling and connecting passage proposed in this invention not only solves the shortcomings of traditional sound and light alarm signal systems, such as complex installation, high cost, insignificant effect, and susceptibility to interference, but also has significant advantages in organizing construction because dedicated personnel check the track in the construction area of ​​the connecting passage and direct the evacuation and relocation of workers near the track at the construction site. In addition to playing the expected role of stabilizing and warning, this signal command system plays a more significant role in organizing construction.

[0045] Example 1

[0046] like Figure 1 As shown, the safety command signal system includes a first track 1 and a second track 2 laid inside the tunnel, as well as an annular groove 3, a rotating disk 5, a third track 6, a first vertical pole 12, a signal light 13, a second vertical pole 14, and an alarm 15. The annular groove 3 is located on the section between the first track 1 and the second track 2. The rotating disk 5 is rotatably connected to the annular groove 3, with its top extending upwards. The third track 6 is fixedly connected to the top of the rotating disk 5, with its two ends respectively connected to the adjacent ends of the first track 1 and the second track 2, forming a complete transport track. Both ends of the third track 6 have an arc surface centered on the rotating disk 5. The first track 1 and the second track 2 are adjacent to each other. Each end of the first track 6 has an arc surface 2 that is connected to the arc surface 1 on the third track 6. When the rotating disk 5 rotates, it can drive the third track 6 to rotate. It can also be connected to the first track 1 and the second track 2 in a reverse-type manner. The first vertical rod 12 is fixedly connected to the top edge of the rotating disk 5. A signal light 13 is fixedly installed at the top of the first vertical rod 12 for indicating the passage of electric vehicles. The second vertical rod 14 is symmetrically arranged with the first vertical rod 12 and is fixedly connected to the top edge of the rotating disk 5. The third track 6 is located between the first vertical rod 12 and the second vertical rod 14. An alarm 15 is fixedly installed at the top of the second vertical rod 14 for warning electric vehicles that do not pass normally.

[0047] like Figures 1-4As shown, the safety command signal system also includes a drive mechanism located within the annular groove 3, used to drive the rotating disk 5 to rotate, thereby achieving the interchange of the two ends of the third track 6. The drive mechanism includes a servo motor 7 fixedly connected to the bottom wall of the annular groove 3. A drive gear 8 is fixedly sleeved on the output shaft of the servo motor 7. A rotating column 4 is rotatably connected to the bottom wall of the annular groove 3, and the top end of the rotating column 4 is fixedly connected to the bottom of the rotating disk 5. A driven gear 9 that meshes with the drive gear 8 is fixedly sleeved on the outer wall of the rotating column 4. When the servo motor 7 is started, the meshing motion of the drive gear 8 and the driven gear 9 drives the rotating column 4 to rotate, which in turn drives the rotating disk 5 to rotate 180 degrees. The rotating disk 5 drives the third track 6 to rotate synchronously by 180 degrees, causing the two ends of the third track 6 to interchange, thus completing the interchangeable docking with the first track 1 and the second track 2.

[0048] In one aspect of this embodiment, such as Figure 2 As shown, a support ring 11 is fixedly connected to the inner wall of the annular groove 3, and the rotating disk 5 is rotatably connected to the top of the support ring 11. The support ring 11 provides support for the rotation of the rotating disk 5, improving its stability and support strength.

[0049] This application can be used in the field of simultaneous implementation of battery-powered vehicle safety command during tunnel boring and connecting passage, and can also be applied to other fields of this application.

[0050] Example 2

[0051] This embodiment is a further improvement on the previous embodiment: such as Figures 1-11 As shown, the shield tunneling and the connecting passage implement a battery-powered vehicle safety command signal system simultaneously, which also includes a warning mechanism on the turntable 5, which works in conjunction with the wheels of the battery-powered vehicle for the automatic alarm of the alarm 15. The warning mechanism includes an L-shaped block 10 fixedly connected to one side of the top of the turntable 5. The L-shaped block 10 is located inside the third track 6 and is lower than the top surface of the third track 6. The top of the L-shaped block 10 is provided with multiple sets of compression components that work in conjunction with the wheels of the battery-powered vehicle, and the compression components work in conjunction with the alarm 15. When the squeezing component is in the forward orientation, the electric vehicle can pass normally, and the wheels will run over the squeezing component normally, but the alarm 15 will not be triggered. However, when the entire L-shaped block 10 rotates 180 degrees with the rotating disk 5, the orientation of the squeezing component on it will change 180 degrees, that is, it will be in the reverse orientation. At this time, the electric vehicle can also pass normally, but when the wheels run over the squeezing component, the alarm 15 will be triggered, reminding the electric vehicle that it is not passing normally, indicating that there are conditions that cannot be entered ahead, and it is necessary to exit the third track 6 and wait.

[0052] In one aspect of this embodiment, such as Figures 1-11As shown, the extrusion assembly includes a mounting groove 16 formed on the top of the L-shaped block 10. A first slide plate 19 is slidably connected inside the mounting groove 16. A first spring 22 is fixedly connected to each of the four bottom corners of the first slide plate 19, and the bottom end of the first spring 22 is fixedly connected to the bottom wall of the mounting groove 16. Two fixing blocks 21 are symmetrically fixedly connected to the top of the first slide plate 19. The two fixing blocks 21 are rotatably connected to the same rotating shaft 17. A pressure plate 18 is fixedly sleeved on the outer wall of the rotating shaft 17. The pressure plate 18 is inclined, with one end extending upward out of the mounting groove 16 and the other end located inside the mounting groove 16 and in contact with the top of the first slide plate 19. A limiting component is provided on the top of the first slide plate 19 for limiting one side of the bottom end of the pressure plate 18. When the extrusion assembly is in the forward orientation, that is, when the pressure plate 18 is in the forward orientation, the wheel of the electric vehicle will press against the high end of the pressure plate 18 when it passes by, and drive the pressure plate 18 to rotate to a horizontal state. The electric vehicle can then travel in the same direction normally. When the extrusion assembly is in the reverse orientation, that is, when the pressure plate 18 has undergone a 180-degree change, the wheel will first come into contact with the high end of the pressure plate 18. The bottom end of the pressure plate 18 is limited by the limiting assembly to prevent the pressure plate 18 from rotating. When the wheel passes by, it will press the pressure plate 18 downward through the high end of the pressure plate 18, causing the pressure plate 18 to move downward as a whole, thereby driving the first slide plate 19 to slide downward and press the first spring 22.

[0053] In one aspect of this embodiment, such as Figures 1-11 As shown, a pressure rod 20 is fixedly connected to the bottom of the first sliding plate 19. A resilient switch 24, located directly below the pressure rod 20 and used in conjunction with it, is fixedly installed on the bottom wall of the mounting groove 16. The resilient switch 24 is electrically connected to the alarm 15. When the first sliding plate 19 slides downward, it simultaneously moves the pressure rod 20 downward. When the first sliding plate 19 moves downward to its maximum stroke, the bottom end of the pressure rod 20 presses down on the resilient switch 24, activating the alarm 15. When the wheel passes the pressure plate 18, the first sliding plate 19 is pushed upward by the elastic action of the first spring 22, and contacts the pressure rod 20 pressing the resilient switch 24. The resilient switch 24 then resets simultaneously, turning off the alarm 15. The upward reset of the first sliding plate 19 also pushes the pressure plate 18 back to its initial state for future use. By setting multiple pressure plates 18 to cooperate with the wheel, the number of alarms can be increased to serve as a warning.

[0054] In one aspect of this embodiment, such as Figures 1-11As shown, a fixing sleeve 25 is fixedly connected to one side of the bottom wall of the mounting groove 16. The top end of the fixing sleeve 25 slides through the top of the first sliding plate 19 and extends upward. A push rod 26 slides through the top end of the fixing sleeve 25. The top end of the push rod 26 abuts against the bottom side of the high end of the pressure plate 18. The bottom end of the push rod 26 is fixedly connected to the bottom wall of the fixing sleeve 25 with the same second spring 27. During the downward sliding of the first sliding plate 19, it can slide up and down on the surface of the fixing sleeve 25, which can play a certain guiding role. At the same time, through the abutment of the push rod 26 against the pressure plate 18, the pressure plate 18 can be tilted under the action of the second spring 27, and the pressure plate 18 can be reset when the electric vehicle passes through and squeezes.

[0055] Example 3

[0056] This embodiment is a further improvement on the previous embodiment: such as Figures 1-11 As shown, the limiting component includes a slider 28 slidably connected to one side of the top of the first slide plate 19. A limiting block 29 is fixedly connected to one side of the slider 28 and used to cooperate with one side of the bottom of the pressure plate 18. The side of the slider 28 away from the limiting block 29 is in contact with one side of the inner wall of the mounting groove 16. The L-shaped block 10 is provided with multiple sets of pushing components that cooperate with the corresponding limiting components. When the pressure plate 18 is in the forward orientation, the limiting block 29 does not resist or limit the pressure plate 18, and the pressure plate 18 can rotate normally. When the rotating disk 5 rotates 180 degrees, the pressure plate 18 is in the reverse orientation. The pushing component can push the slider 28 to slide and drive the limiting block 29 to move above the bottom side of the pressure plate 18 and press against its top side, thereby achieving the effect of limiting the rotation of the pressure plate 18. Combined with the resistance and limitation of the limiting block 29 and the first sliding plate 19 on the pressure plate 18, the pressure plate 18 cannot rotate and can only move downward under pressure. Therefore, in the reverse orientation, it can only drive the first sliding plate 19 downward and trigger the alarm 15 to sound an alarm.

[0057] In one aspect of this embodiment, such as Figures 1-11As shown, the pushing assembly includes a mounting cavity 23 located inside the L-shaped block 10 and on one side of the mounting groove 16. A second sliding plate 34 is slidably connected inside the mounting cavity 23. A plurality of third springs 37 are fixedly connected between the top of the second sliding plate 34 and the top wall of the mounting cavity 23. A push plate 32 is slidably connected through the top of the top wall of the mounting cavity 23 near the mounting groove 16. One side of the push plate 32 extends into the mounting groove 16 and is symmetrically fixedly connected to two convex sliders 31. Two corresponding sliders 31 are symmetrically opened on the side of the slider 28 away from the limiting block 29. The convex slider 31 is slidably connected to the convex groove 30. The bottom of the push plate 32 is fixedly connected to the upper connecting seat 33. The top of the second slide plate 34 is fixedly connected to the lower connecting seat 35. The upper connecting seat 33 and the lower connecting seat 35 are rotatably connected to the same rotating plate 36. The bottom of the second slide plate 34 is fixedly connected to the third vertical rod 38. The bottom end of the third vertical rod 38 slides through the bottom of the L-shaped block 10 and the rotating disk 5 and extends downward into the annular groove 3. A trapezoidal plate 39 that cooperates with the third vertical rod 38 is fixedly connected to one side of the bottom wall of the annular groove 3. When the pressure plate 18 is in the forward orientation, the third vertical rod 38 does not contact the trapezoidal plate 39. Under the action of the third spring 37, it will not slide through the push plate 32, and thus will not move through the slider 28 to move the limiting block 29 to abut and limit the pressure plate 18. When the pressure plate 18 is in the reverse orientation, the rotating disk 5 synchronously drives the third vertical rod 38 to rotate 180 degrees. At this time, the third vertical rod 38 abuts against the top of the trapezoidal plate 39, and during the movement, the inclined surface of the trapezoidal plate 39 will push the third vertical rod 38 towards... The upper slide lifts the first slide plate 19, causing the second slide plate 34 to slide upward and compress the third spring 37. This, in turn, causes the rotating plate 36 to drive the push plate 32 to extend and slide into the mounting groove 16. This causes the slider 28 to move the limiting block 29, thereby achieving contact and limiting of the pressure plate 18. During the downward sliding of the first slide plate 19, the slider 28 and the limiting block 29 can be moved downward simultaneously. At this time, the slider 28 can slide downward on one side of the push plate 32 through the sliding cooperation between the convex slider 31 and the convex groove 30.

[0058] Example 4

[0059] This embodiment is a further improvement on the previous embodiment: such as Figures 1-3 As shown, there are two signal lights 13, symmetrically arranged one in front of the other at the top of the first vertical pole 12, and the two signal lights 13 emit different colors of light. The two signal lights 13 use red and yellow lights respectively for indication. The red light indicates that passage is prohibited, and the yellow light indicates that passage is permitted at a slow speed. The driver of the electric vehicle can judge whether it is permissible to pass based on the light emitted by the signal lights 13, so as to ensure the safety of transportation in the tunnel.

[0060] Working principle: First, a switch control box is installed at a suitable location inside the tunnel to control the start-up of signal light 13 and servo motor 7, and is managed by designated personnel. When the connecting passage is being excavated, signal light 13 is adjusted to red via the switch control box, prohibiting electric vehicles from passing through the area. When an electric vehicle needs to pass through the area, the driver communicates with the control personnel, who, ensuring the safety of on-site workers, adjusts signal light 13 to yellow, allowing the electric vehicle to slowly pass through the area.

[0061] When the pressure plate 18 is in the forward orientation, such as Figure 1 , Figure 5 As shown, the corresponding signal light 13 is yellow at this time, and the electric vehicle can pass normally. When the wheel passes the pressure plate 18, it will not cause the first sliding plate 19 to slide down, and thus will not touch the elastic switch 24. The alarm 15 will not sound an alarm.

[0062] When the conditions inside the tunnel are not suitable for the electric vehicle to enter, the person in charge starts the servo motor 7 to drive the rotating disk 5 to rotate 180 degrees, reversing the two ends of the third track 6, and then reconnecting it with the first track 1 and the second track 2. At the same time, the signal light 13 changes from yellow to red, indicating that passage is prohibited. At this time, the pressure plate 18 is in the reverse position. Figure 12 As shown, the third vertical rod 38 abuts against the top of the trapezoidal plate 39 and pushes the third vertical rod 38 upward, thereby driving the limiting block 29 to move above the bottom side of the pressure plate 18 and abut against it, thus achieving the abutment and limitation of the pressure plate 18. At this time, the electric vehicle can also pass normally. However, during the passage, the wheels will press the pressure plate 18 downward, but the pressure plate 18 will not rotate. At the same time, it will drive the first sliding plate 19 to slide down, touch and squeeze the elastic switch 24, activate the alarm 15, and warn the driver on the passing electric vehicle not to enter. This can prevent accidental entry when the driver is not paying attention. The alarm 15 can also warn the person in charge on site, improving the construction safety in the tunnel.

[0063] This safety command and signal control system not only solves the problem of electric vehicle drivers not being able to understand the specific situation on the track ahead in a timely manner, but also allows on-site workers, materials, and equipment to evacuate to a safe area in a timely manner. It effectively ensures the safety of the construction of the connecting tunnel and the transportation of electric vehicles during the overlapping construction operations. Moreover, compared with traditional audible and visual warning light devices, this safety signal command and control device is more reliable due to the dedicated command signal control method. It overcomes the drawback of audible and visual alarm devices being unable to function properly due to noise interference from on-site construction equipment. It can take more reasonable command signals according to specific situations and can also remind electric vehicle drivers. It also has significant advantages in terms of cost control. The system is low-cost, easy to install, and cost-effective, which greatly reduces the cost investment in safety management during the simultaneous construction of shield tunneling and connecting tunnels.

[0064] However, as is well known to those skilled in the art, the working principle and wiring method of the servo motor 7 are commonplace and are all conventional methods or common knowledge, so they will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
