[0002] TBM (Tunnel Boring Machine) is a high-performance mechanical equipment used in tunnel construction. It can realize the integrated operation of tunnel excavation, support and mucking. The working principle of TBM is based on the cutting and crushing of rocks by a rotating cutterhead. The cutterhead is equipped with multiple rollers, which apply pressure to the rock, crushing it for excavation. The propulsion force of TBM comes from the support shoes and jacks, which work together on the tunnel wall to push the machine forward. The construction efficiency of TBM is much higher than that of traditional drilling and blasting methods, which can significantly reduce construction risks and improve construction safety and quality.

[0003] During the tunneling process, the tunnel boring machine needs to transport the slag out of the construction hole and transport concrete, flat materials, construction equipment and construction personnel into the hole. In order to facilitate transportation, the existing technology uses rail transportation, laying tracks in advance, and gradually laying tracks forward according to the progress of tunneling. The existing track laying uses temporary assembly of I-beams and sleepers, which is not convenient for installation, and is in a completely fixed state after installation. It is not easy to disassemble during transfer, nor is it easy to repair and replace. To this end, we propose a rail transportation system for TBM tunneling construction. Summary of the invention

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] Embodiment 1:

[0028] like Figure 1-3 As shown, a rail transportation system in a TBM excavation construction tunnel includes a first guide rail 1 and a second guide rail 2. The bottom of the first guide rail 1 and the second guide rail 2 is provided with equidistant sleepers 3. Three to five sleepers 3 are provided, and can also be adjusted as needed. The first guide rail 1, the second guide rail 2 and a plurality of sleepers 3 are connected to form a detachable track structure. A first connecting plate 4 is provided at one end of the track structure, and a second connecting plate 5 is provided at the other end. The first connecting plate 4 is fixed to the sleeper 3 at the head end of the track structure, and the second connecting plate 5 is fixed to the sleeper 3 at the end of the track structure. The track structure is formed by combining the first guide rail 1, the second guide rail 2 and a plurality of sleepers 3, and connecting plates are provided at both ends of the track structure. Pin holes are provided on the connecting plates, and the pin shafts 8 are inserted into the pin holes and fixed by nuts 9, so as to achieve simple and fast installation and disassembly.

[0029] Pin holes are provided on the first connecting plate 4 and the second connecting plate 5 , and two adjacent track structures are connected by the first connecting plate 4 and the second connecting plate 5 . The pin holes of the first connecting plate 4 and the second connecting plate 5 overlap and are fixed by a pin shaft 8 and a nut 9 .

[0030] It also includes a pin detection mechanism and an indicator light. The pin detection mechanism is used to detect whether the pin 8 in the pin hole has fallen off; the indicator light is used to prompt the information that the pin 8 has fallen off. By setting the pin sensor, it is possible to monitor whether the pin 8 has fallen off, so as to prevent the detachable track structure from falling off due to repeated crushing by vehicles such as diesel locomotives, rail-mounted concrete tankers, rail-mounted flatbed material vehicles, and rail-mounted people carriers, causing instability. It is easy to install and ensures safety. When the pin sensor senses the pin 8, the indicator light is always on and the driver can see it directly. When the pin sensor senses the pin 8, the indicator light is flashing to remind the driver to pay attention to safety and perform maintenance.

[0031] Embodiment 2:

[0032] like Figure 1-3As shown, on the basis of the first embodiment, the first connecting plate 4 and the second connecting plate 5 are staggered in height. When two adjacent track structures are connected, the first connecting plate 4 is located at the top, the second connecting plate 5 is located at the bottom, the indicator light is located above the first connecting plate 4, and the pin shaft detection mechanism is located below the second connecting plate 5. By staggering the first connecting plate 4 and the second connecting plate 5, it is convenient to align the pin holes on the two. By arranging the pin shaft detection mechanism below the second connecting plate 5, it is avoided that the pin shaft detection mechanism is squeezed during the installation of the first connecting plate 4 and the second connecting plate 5.

[0033] The pin holes include a first pin hole 6 and a second pin hole 7. A first pin shaft sensor 10 is provided at the bottom of the second connecting plate 5 corresponding to the first pin hole 6. A second pin shaft sensor 11 is provided at the bottom of the second connecting plate 5 corresponding to the second pin hole 7. If any one of the first pin shaft sensor 10 and the second pin shaft sensor 11 detects that the pin shaft 8 has fallen off, the first indicator light 15 above the first connecting plate 4 will flash to remind. By setting two pin holes, the stability of the two connecting plates after connection can be improved. The rotational offset of the two track structures after connection can be avoided. Two pin shaft sensors are set for the two pin holes. If the pin shaft 8 in any one of the pin holes falls off, it will affect the stability of the track structure. The first indicator light 15 flashes to remind the driver to repair it in time to avoid accidents.

[0034] The first pin sensor 10 and the second pin sensor 11 both use fiber optic diffuse reflection sensors, which are aligned with the pin 8 to detect whether it exists. The fiber optic diffuse reflection sensor is a device that uses optical fiber as a sensing element. It detects the existence, position or other physical quantities of an object by measuring the reflection characteristics of light. This sensor is usually composed of a light source, an optical fiber, a photodetector and a signal processing system. The light emitted by the light source is transmitted to the object to be measured through the optical fiber and is reflected by the object. The reflected light is transmitted to the photodetector again through the optical fiber. The detector converts the received light signal into an electrical signal, thereby realizing the detection and measurement of the object.

[0035] Embodiment three:

[0036] like Figure 2 As shown, on the basis of the second embodiment, a horizontal sensor 12 is provided at the bottom of the first connecting plate 4 and the second connecting plate 5, and the horizontal sensor 12 at the bottom of the first connecting plate 4 is provided in a non-overlapping area of ​​the first connecting plate 4 and the second connecting plate 5. When any one of the two horizontal sensors 12 detects an abnormality, the second indicator light 16 above the first connecting plate 4 flashes to give a prompt.

[0037] The horizontal sensor 12 directly changes the output result after the azimuth change of the operating environment. It is used to measure the inclination angle of the track structure in the horizontal direction. The horizontal sensor 12 can measure the horizontal angles in two directions at the same time, so it can determine the horizontality of the entire measured surface. Under the repeated rolling of vehicles such as diesel locomotives, rail-mounted concrete tankers, rail-mounted flatbed material vehicles, and rail-mounted man-carrying vehicles, the track structure is prone to tilt to one side due to the inconsistent weight on both sides of the vehicle loading, that is, the whole tilts to one side of the first guide rail 1 or the second guide rail 2. When the horizontal sensor 12 detects a change in data, the second indicator light 16 flashes to remind the driver that the track structure is tilted. When the horizontal sensor 12 does not detect a change in data, the second indicator light 16 is always on, which also serves as a reminder.

[0038] Embodiment 4:

[0039] like Figure 4-6 As shown, the head end of the track structure is provided with a flatness sensor receiving end 14 installed on the sleeper 3, and the end of the track structure is provided with a flatness sensor transmitting end 13 installed on the sleeper 3. After the two adjacent track structures are connected, the flatness sensor transmitting end 13 at the end of one track structure is aligned with the flatness sensor receiving end 14 at the head end of the other track structure. Since the track structure adopts a detachable installation method, the connection is prone to deformation or loosening under the repeated rolling of vehicles such as diesel locomotives, rail-mounted concrete tankers, rail-mounted flat material vehicles, and rail-mounted people vehicles. Even if the pin shaft 8 does not fall off, it will affect the flatness of the entire track, and the flatness will affect the driving comfort and safety of the vehicle. The opposite-beam optical fiber mirror reflection sensor can detect whether two adjacent track structures are in the same straight line.

[0040] The flatness sensor transmitting end 13 and the flatness sensor receiving end 14 adopt a through-beam optical fiber mirror reflection sensor. When the through-beam optical fiber mirror reflection sensor cannot detect a signal, a third indicator light 17 above the first connecting plate 4 flashes to provide a prompt.

[0041] The opposite-beam optical fiber mirror reflection sensor is a photoelectric sensor that uses optical fiber to transmit the light beam emitted by the light source to a reflective surface and then reflects it back to the sensor's receiver. The sensor consists of a transmitter, a receiver and an optical fiber. The transmitter and the receiver are connected by optical fiber to form a opposite-beam detection structure. When any of the two connected track structures is deformed or tilted, the light signal received by the receiver will change, thereby detecting that the track is deformed and the flatness has deteriorated. The third indicator light 17 flashes to indicate that the flatness is normal when the light signal received by the receiver does not change. The first indicator light 15 and the third indicator light 17 are respectively arranged at the two ends above the first connecting plate 4, and the second indicator light 16 is arranged at the center position above the first connecting plate 4. The indicator lights arranged at different positions are convenient for the driver to judge different fault conditions according to the flashing of different indicator lights. In addition, the indicator lights can also be set to different colors.

[0042] Embodiment five:

[0043] like Figure 2 As shown, a micro wind generator 18 is installed on the first connecting plate 4, and a battery 19 is arranged at the bottom of the first connecting plate 4. The micro wind generator 18 is used to convert the wind power of the locomotive into electricity and store it in the battery 19. The battery 19 is used to power the electrical appliances on the first connecting plate 4 and the second connecting plate 5 connected by the pin 8. Since there are many vehicles running on the track, the wind energy generated by the vehicles can be recycled and reused through the micro wind generator 18. In addition, a wire can be arranged to charge the battery 19.

[0044] The battery 19 is provided with a locator 20, which is used to number and locate a single track structure. The battery 19 is provided with a communication module 21, which is used to send the data detected by each sensor to a remote computer or mobile terminal. The locator 20 has a built-in GPS module, and the communication module 21 uses a mobile communication module, which can send the positioning data obtained by the GPS module to the server through the mobile communication network, thereby realizing real-time positioning and tracking. At the same time, the data detected by each sensor is sent to the server through the mobile communication network. To achieve remote monitoring.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
