Description

Technical Field

[0001] The present invention relates to the technical field of TBM support for coal tunnels, and in particular to a trailer system for a TBM tunneling machine and a TBM tunneling machine. Background Art

[0002] During the excavation process, a TBM tunneling machine needs to be equipped with a variety of functional boxes to achieve functions such as power supply, ventilation, and cooling. Traditional TBM tunneling machines usually connect various functional modules at the rear end of the main beam. The functional modules are arranged and connected in a primary and secondary relationship and are all dragged to the rear of the TBM tunneling machine's main beam. In addition, each functional module is usually provided with a slide rail at the bottom, and a track is provided at the bottom of the tunnel. During the excavation process, the main beam pulls the various functional modules forward through the cooperation of the slide rail and the track. However, in coal mine tunnels, for example, due to problems such as coal gangue debris and mud residue, the above-mentioned tracks can easily be blocked, resulting in the main beam being unable to move forward smoothly when pulling the functional modules, or even unable to move forward at all. In severe cases, the main beam or the connection between the main beam and the functional modules may be deformed or directly broken.

[0003] Moreover, traditional TBMs integrate all functional modules needed in coal mines behind the main beam, regardless of when and where each functional module is used. This results in a huge number of functional modules that need to be dragged behind the main beam, and the length is too long, which creates great difficulties for excavation and leads to the problem of abnormal excavation. Summary of the Invention

[0004] The object of the present invention is to solve at least one technical problem in the background technology and to provide a trailer system for a TBM tunneling machine and a TBM tunneling machine.

[0005] To achieve the above objectives, the present invention provides a trailer system for a TBM (Turbine Boring Machine), comprising: a first trailer mechanism and a second trailer mechanism, wherein the first trailer mechanism has a connection portion for connecting to a main body of the TBM and includes a plurality of mutually detachably connected functional structures; the second trailer mechanism includes a slide rail structure disposed above the first trailer mechanism and a backup functional structure hoisted on the slide rail structure, wherein the backup functional structure is detachably hoisted on the slide rail structure and can reciprocate along the slide rail structure;

[0006] The backup functional structure moves with the functional structure. The backup functional structure can reciprocate along the direction approaching and away from the first trailer mechanism. The functional structure can reciprocate along the direction approaching and away from the second trailer mechanism.

[0007] According to one aspect of the present invention, the backup function structure includes a backup function box and a backup function trailer, and the backup function box is loaded on the backup function trailer.

[0008] According to one aspect of the present invention, the functional structure includes a trailer and a main functional box detachably mounted on the trailer, and the trailer and the main functional box can be reciprocated in a direction approaching and away from the second trailer mechanism, or the main functional box can be reciprocated in a direction approaching and away from the second trailer mechanism.

[0009] According to one aspect of the present invention, the standby function box is installed on the empty trailer in the first trailer mechanism through a transfer structure.

[0010] According to one aspect of the present invention, the backup function trailer is installed behind the trailer.

[0011] According to one aspect of the present invention, the functional structure includes a first trailer provided with a main functional box and an empty second trailer, and the first trailer and / or the second trailer can be transported and hoisted in the second trailer mechanism.

[0012] According to one aspect of the present invention, the standby function box is installed on the unloaded second trailer via a transfer structure.

[0013] According to one aspect of the present invention, the length of the slide rail structure is longer than that of the first trailer mechanism, and when the slide rail structure is projected toward the first trailer mechanism, both ends of the slide rail structure are located outside both ends of the first trailer mechanism.

[0014] According to one aspect of the present invention, the slide rail structure includes a plurality of slide rails connected end to end, and each of the slide rails is detachably mounted above the first trailer mechanism via a sling structure.

[0015] According to one aspect of the present invention, the sling structure includes a sling and a locking member detachably connected to the slide rail, and the locking member includes a sensor for determining whether a spare function box is hoisted on the slide rail and a locking device electrically connected to the sensor;

[0016] The locker locks the sling and the slide rail or releases the sling and the slide rail according to the signal of the sensor.

[0017] According to one aspect of the present invention, a waterproof structure is provided on the slide rail.

[0018] To achieve the above objectives, the present invention also provides a TBM tunneling machine and a trailer system for the TBM tunneling machine.

[0019] According to one solution of the present invention, the first trailer mechanism can move forward in a wheel-walking manner driven by the TBM tunneling machine, which can solve the problem of easy slag jamming in the traditional solution using slide rails for movement. Furthermore, the functional structure in the first trailer mechanism can be hoisted in the second trailer mechanism, and the spare functional structure in the second trailer mechanism can be transferred and installed in the first trailer mechanism. Such an arrangement can effectively reduce the functional structure towed behind the TBM tunneling machine, and can increase the corresponding functional modules as needed. For example, when the TBM tunneling machine is working, it only needs electricity and cooling. Then, the functional structure in the first trailer mechanism only needs to be equipped with an electric box and a cooling box, and other functional boxes do not need to be equipped in the functional structure in the first trailer mechanism 1. At this time, the unused functional boxes can be hoisted as spare boxes in the second trailer mechanism. The spare functional structure is installed on the slide rail structure in the second trailer mechanism, and when it is needed, the spare functional structure on the slide rail structure in the second trailer mechanism is transferred and installed in the first trailer mechanism. This can greatly reduce the pressure of the TBM tunneling machine's rear transportation, ensure the speed and efficiency of the TBM tunneling machine, and greatly reduce energy utilization. It also makes the use of the TBM tunneling machine trailer system more flexible and convenient. The spare functional structure hoisted on the top of the tunnel completely avoids the operating space, making the tunnel more simple and safe, and the movement of the spare functional structure is smoother, which effectively improves the working efficiency of the TBM tunneling machine and reduces the safety risks in the tunnel.

[0020] According to one aspect of the present invention, the backup function structure includes a backup function box and a backup function trailer, wherein the backup function trailer is loaded with the function box. In other words, the backup function structure includes both the backup function box not loaded on the function trailer and the backup function trailer loaded with the function box via the trailer. With this arrangement, when installing the backup function structure in the first trailer mechanism, the backup function box can be directly installed on the unloaded trailer in the first trailer mechanism, or the backup function trailer can be directly installed behind the trailer in the first trailer mechanism, making function selection, planning, and installation simpler and more efficient.

[0021] According to one solution of the present invention, the functional structure includes a trailer and a main functional box detachably mounted on the trailer. The trailer and the main functional box can be transported and hoisted in a non-trailer mechanism, or the main functional box can be transported and hoisted in a second trailer mechanism. The functional structure includes a trailer and a main functional box detachably mounted on the trailer. In this way, when the main functional box is used up, the main functional box can be removed and hoisted on the slide rail structure in the second trailer mechanism. Then, the spare functional structure to be used can be removed from the slide rail structure and installed on an empty trailer or at the rear of the trailer through the transport structure. In this way, the corresponding functional boxes can be arranged and set according to the needs of the TBM tunneling machine to ensure various tasks during the tunneling process. Moreover, when performing various tasks, the functional boxes towed behind the TBM tunneling machine are streamlined, which will not cause reverse pulling force on the tunneling, thereby ensuring smooth and safe tunneling. In addition, the present invention can also hoist the trailer and the main functional box together on the slide rail structure in the second trailer mechanism, which can further ensure that the trailer and functional box behind the TBM tunneling machine are streamlined and the reverse pulling force of the TBM tunneling machine is minimized.

[0022] According to one aspect of the present invention, the functional structure includes a first trailer equipped with a primary functional housing and an unloaded second trailer. The first trailer and / or the second trailer can be transferred and hoisted within the second trailer mechanism. This arrangement allows the backup functional housing to be installed on the unloaded second trailer, ensuring that the primary functional housing always follows the TBM during excavation, while the backup functional housing can be installed on the second trailer as needed. Furthermore, the first trailer and / or the second trailer can be transferred and hoisted within the second trailer mechanism. This arrangement allows the first and second trailers to be lifted as needed to ensure smooth and unimpeded progress of corresponding work within the tunnel.

[0023] According to one aspect of the present invention, the length of the slide rail structure is longer than the length of the first trailer mechanism, and when the slide rail structure is projected toward the first trailer mechanism, both ends of the slide rail structure are located outside the ends of the first trailer mechanism. This arrangement allows for clearance between the standby functional structure and the functional structure. The standby functional structure and the functional structure suspended on the slide rail structure can be moved toward the ends of the slide rail structure, and the installation gap can be adjusted, thus resolving the problem of all structures needing to be stacked toward the rear of the slide rail structure.

[0024] According to one embodiment of the present invention, the slide rail structure comprises multiple sections of slide rails connected end to end, each of which is detachably mounted to the tunnel roof via a sling structure. This arrangement allows unloaded slide rails to be moved in the direction of excavation, ensuring the transport and movement of both the standby and functional structures.

[0025] According to one embodiment of the present invention, a sling structure includes a sling detachably connected to a slide rail and a locking member. The locking member includes a sensor that determines whether a backup functional structure is mounted on the slide rail and a locking device electrically connected to the sensor. The locking device can lock or release the sling and slide rail based on a signal from the sensor. This arrangement provides a safety feature, ensuring that the object does not fall off when being hoisted.

[0026] According to one solution of the present invention, a waterproof structure, such as a waterproof cloth, is provided above the slide rail. This arrangement can prevent mud and water in the tunnel, ensure that the slide rail and the structure below it are dry and clean and not corroded, and ensure the safety of the tunnel.

[0027] According to the solution of the present invention, functional modules can be transferred between the first trailer mechanism and the second trailer mechanism. In this way, functional modules can be added to the rear of the TBM tunneling machine as needed. When not needed, the corresponding functional modules can be hoisted above the tunnel. This can ensure that the reverse pulling force at the rear of the TBM tunneling machine is effectively reduced, ensuring the smooth progress of tunneling. At the same time, it can effectively shorten the towing length of the TBM tunneling machine and improve the tunneling speed and efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Figure 2 The figure schematically shows the structural arrangement of a trailer system for a TBM tunneling machine according to another embodiment of the present invention. DETAILED DESCRIPTION

[0030] The present invention will now be discussed with reference to exemplary embodiments. It should be understood that the embodiments discussed are only intended to enable those skilled in the art to better understand and implement the present invention, rather than to imply any limitation on the scope of the present invention.

[0031] As used herein, the term "including" and variations thereof are to be interpreted as open-ended terms meaning "including, but not limited to." The term "based on" is to be interpreted as "based, at least in part, on." The terms "one embodiment" and "an embodiment" are to be interpreted as "at least one embodiment."

[0032] Figure 1 The following schematically shows the structural arrangement of a trailer system for a TBM tunneling machine according to an embodiment of the present invention. Figure 1As shown, in this embodiment, a trailer system for a TBM (Tunnel Boring Machine) includes a first trailer mechanism 1 and a second trailer mechanism 2. The first trailer mechanism 1 is connected to the TBM and includes multiple detachably connected functional structures 101. The second trailer mechanism 2 includes a slide rail structure 201 disposed at the top of the tunnel and a backup functional structure 202 hoisted on the slide rail structure 201. The backup functional structure 202 is detachably hoisted on the slide rail structure 201 and can reciprocate along the slide rail structure 201. In this embodiment, the backup functional structure 202 moves with the functional structure 101 and can be transferred and installed in the first trailer mechanism 1, while the functional structure 101 can be transferred and hoisted in the second trailer mechanism 2. In this embodiment, the first trailer mechanism 1 can move forward using wheels driven by the TBM, which solves the problem of slag jamming caused by slide rail movement in traditional solutions. Furthermore, the functional structure 101 in the first trailer mechanism 1 can be hoisted in the second trailer mechanism 2, and the spare functional structure 202 in the second trailer mechanism 2 can be transferred and installed in the first trailer mechanism 1. Such an arrangement can effectively reduce the functional structure 101 towed behind the TBM tunneling machine, and can increase the corresponding functional modules as needed. For example, when the TBM tunneling machine is working, it only needs electricity and cooling. Then the functional structure 101 in the first trailer mechanism 1 only needs to be equipped with an electric box and a cooling box, while other functional boxes (such as dust removal ventilation boxes and grease boxes, etc.) do not need to be equipped in the functional structure 101 in the first trailer mechanism 1. At this time, the unused functional boxes can be hoisted in the second trailer mechanism as spare boxes. The spare functional structure 202 on the slide rail structure 201 in the mechanism 2 can be transferred and installed (for example, by lifting and installing it through a wire rope) on the slide rail structure 201 in the second trailer mechanism 2 to the first trailer mechanism 1 when it is needed. This can greatly reduce the pressure of the TBM tunneling machine's rear transportation, ensure the speed and efficiency of the TBM tunneling machine's tunneling, and greatly reduce energy utilization. It also makes the use of the TBM tunneling machine trailer system more flexible and convenient. The spare functional structure 202 hoisted on the top of the tunnel completely avoids the operating space, making the tunnel more simple and safe, and the movement of the spare functional structure 202 is smoother, which effectively improves the working efficiency of the TBM tunneling machine and reduces the safety risks in the tunnel.

[0033] Furthermore, in this embodiment, the standby function structure 202 includes a standby function box 2021 and a standby function trailer, wherein the standby function trailer is loaded with the standby function box, that is, the standby function structure 202 includes both the standby function box 2021 not loaded on the function trailer and the standby function trailer (not shown) loaded with the standby function box via the trailer. With this arrangement, when the standby function structure 202 is installed in the first trailer mechanism 1, the standby function box 2021 can be directly installed on the unloaded trailer in the first trailer mechanism 1, or the standby function trailer can be directly installed behind the trailer in the first trailer mechanism 1, making function selection, planning, and installation simpler and more efficient.

[0034] Furthermore, if Figure 1 As shown, in this embodiment, the functional structure 101 includes a trailer 1011 and a main functional box 1012 detachably mounted on the trailer 1011. The trailer 1011 and the main functional box 1012 can be transported and hoisted in a non-trailer mechanism 2, or the main functional box 1012 can be transported and hoisted in a second trailer mechanism 2. In this embodiment, the functional structure 101 includes a trailer 1011 and a main functional box 1012 detachably mounted on the trailer 1011. In this way, when the main functional box 1012 is used, the main functional box 1012 can be unloaded and hoisted on the slide rail structure 201 in the second trailer mechanism 2, and then the spare functional structure 202 to be used is unloaded from the slide rail structure 201 and installed on the empty trailer 1011 or at the rear of the trailer 1011 through a transport structure (such as a steel wire rope). This allows for the arrangement of corresponding functional boxes according to the needs of the TBM, ensuring the various tasks during the tunneling process. Furthermore, the number of functional boxes towed behind the TBM during each task is reduced, preventing reverse pull on the tunneling process and ensuring smooth and safe tunneling. Furthermore, according to another embodiment of the present invention, the trailer 1011 and the main functional box 1012 can be hoisted together on the slide rail structure 201 in the second trailer mechanism 2. This further reduces the number of trailers and functional boxes behind the TBM, minimizing reverse pull on the TBM.

[0035] Further, Figure 2 A schematic diagram of the structural arrangement of a trailer system for a TBM tunneling machine according to another embodiment of the present invention is shown as follows: Figure 2As shown, according to another embodiment of the present invention, the functional structure 101 includes a first trailer 1013 equipped with a main functional box 1012 and an unloaded second trailer 1014. The first trailer 1013 and / or the second trailer 1014 can be transported and hoisted in the second trailer mechanism 2. This arrangement allows the backup functional box 2021 to be installed on the unloaded second trailer 1014, ensuring that the main functional box 1012 always follows the TBM during excavation, while the backup functional box 2021 can be installed on the second trailer 1014 as needed. Moreover, in this embodiment, the first trailer 1013 and / or the second trailer 1014 can be transported and hoisted in the second trailer mechanism. This arrangement allows the first trailer 1013 and the second trailer 1014 to be lifted as needed to ensure that the corresponding work in the tunnel can proceed smoothly and unimpeded.

[0036] Furthermore, in the present invention, the length of the slide rail structure 201 is longer than the length of the first trailer mechanism 1, and when the slide rail structure 201 is projected toward the first trailer mechanism 1, both ends of the slide rail structure 201 are located outside the ends of the first trailer mechanism 1. This arrangement allows for clearance between the standby functional structure 202 and the functional structure 101. The standby functional structure 202 and the functional structure 101 suspended on the slide rail structure 201 can be moved toward the ends of the slide rail structure 201 and the installation gap can be adjusted, thus resolving the problem of all structures needing to be stacked toward the rear of the slide rail structure 201.

[0037] Further, if Figure 1 As shown, in this embodiment, the slide rail structure 201 includes multiple sections of slide rails 2011 connected end to end, and each slide rail 2011 is detachably mounted on the top of the tunnel via a sling structure 3. This arrangement allows the unloaded slide rails 2011 to move in the direction of excavation, ensuring the transportation and movement of the backup functional structure 202 and the functional structure 101.

[0038] Furthermore, in this embodiment, the sling structure 3 includes a sling 301 detachably connected to the slide rail 2011 and a locking member (not shown in the figure), wherein the locking member includes a sensor for determining whether the backup functional structure 202 is hoisted on the slide rail 2011 and a locking device electrically connected to the sensor; the locking device can lock the sling and the slide rail 2011 or release the sling and the slide rail 2011 according to the signal from the sensor. This arrangement can serve as a safety function, that is, a safety locking is performed to ensure that the heavy object will not fall off when being hoisted.

[0039] Furthermore, in this embodiment, a waterproof structure, such as a waterproof cloth, is provided above the slide rail 2011. This arrangement can prevent mud and water in the tunnel, ensure that the slide rail 2011 and the structure below it are dry and clean and not corroded, and ensure the safety of the tunnel.

[0040] In addition, in order to achieve the above-mentioned purpose, the present invention also provides a TBM tunneling machine, including the above-mentioned trailer system for the TBM tunneling machine.

[0041] According to the above scheme of the present invention, functional modules (i.e., spare functional structure 202 and functional structure 101) can be transferred between the first trailer mechanism 1 and the second trailer mechanism 2. In this way, functional modules can be added to the rear of the TBM tunneling machine as needed. When not needed, the corresponding functional modules can be hoisted above the tunnel. This can ensure that the reverse pulling force at the rear of the TBM tunneling machine is effectively reduced, ensuring the smooth progress of tunneling. At the same time, it can effectively shorten the towing length of the TBM tunneling machine and improve the tunneling speed and efficiency.

[0042] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
