Description

Technical Field

[0001] This utility model relates to the field of rail transportation technology, and in particular to a TBM trailer rail rapid transportation device. Background Technology

[0002] In the construction process of tunneling machines such as tunnel boring machines (TBMs), the cyclic laying of trailer tracks is an essential and crucial step. Typically, the tracks need to be removed from the rear of the trailer and transported to the front for cyclic laying. However, current TBMs and TBMs use a wheel-rail system, which limits tunnel space. After the trailer tracks and sleepers are removed from the rear, their weight necessitates 2-3 people to carry them each time. This not only consumes a significant amount of physical labor for track transport but is also inefficient and poses safety risks.

[0003] In recent years, there have been many research results on the design and methods of trailer wheelsets for the application of TBMs in mining projects, especially the inclined wheelset method, such as the inclined wheelset and trailer disclosed in the utility model patent with authorization announcement number CN221316449U. However, its overall operation is relatively cumbersome, and the geological conditions in coal mines are generally poor, resulting in low adaptability of inclined wheelsets in coal mine roadways. Therefore, there is still a need to use wheel-rail trailers.

[0004] A search of existing technologies reveals various transportation devices, such as the utility model patent with authorization publication number CN211034165U, which discloses a circular conveyor line, and another utility model patent with authorization publication number CN203306573U, which discloses an automatic transport machine. However, these existing technologies not only differ from the application field of this application, but also cannot be used for reliable rail transport, especially failing to meet the requirements for forward transport and directional adjustment of the rail.

[0005] In conclusion, it is necessary to design a rapid rail transport device to solve the problems existing in rail transport, improve rail transport efficiency, and reduce the labor intensity of operations.

[0006] It should be noted that the above technical information is intended only to enhance the understanding of the overall background technology of this utility model, and should not be regarded as an admission or in any form implying that the above technical information constitutes prior art known to those skilled in the art. Utility Model Content

[0007] To address the shortcomings in the aforementioned background technology, this utility model proposes a TBM trailer rail rapid transport device, the technical problem to be solved being: how to improve rail transport efficiency and reduce labor intensity.

[0008] The technical solution of this utility model is as follows: A TBM trailer-mounted rail rapid transport device includes several carrier wheels arranged along the rail transport direction. Each carrier wheel is used to rotate and transport the rail located above it. Correcting wheels are arranged on both sides of each carrier wheel to guide the rail. This technical solution includes several carrier wheels and several correcting wheels. The distance between adjacent carrier wheels is less than the length of a single rail. Similarly, along the transport direction, the distance between adjacent correcting wheels is also less than the length of a single rail. In the left-right direction perpendicular to the transport direction, the correcting wheels on the left and right sides can be arranged symmetrically or at intervals. It should be noted that the carrier wheels can be driven manually or by a drive device. The correcting wheels can be driven by a drive device or not. During the rail transport process driven by the carrier wheels, because the vertical distance between the correcting wheels on the left and right sides is greater than the width of the rail, and the height of the top surface of the rail is higher than the height of the bottom surface of the correcting wheel, when the rail tilts, the rail and the correcting wheels come into contact with each other. The correcting wheels are subjected to friction and rotate, ensuring that the rail is always transported in the predetermined target direction.

[0009] Based on the above technical solutions, as a preferred technical solution for the TBM trailer rail rapid transport device, the distance between adjacent load-bearing wheels is less than the length of the track. Each load-bearing wheel is connected to a gear, and the gears are connected via chain drive. At least one gear is connected to a drive device. This technical solution provides a preferred embodiment for driving the load-bearing wheels, namely, using a chain drive mechanism. In this chain drive mechanism, only one drive device, one chain, and corresponding gear are needed to achieve transmission. Of course, multiple drive devices, one chain, and corresponding gears can also be used, requiring the synchronization of each drive device to be ensured. Alternatively, multiple drive devices, multiple chains, and corresponding gears can be used, with each drive device corresponding to one chain, and each chain corresponding to one or more gears. In this case, it is not necessary to ensure the synchronization of each drive device.

[0010] Based on the above technical solutions, as a preferred technical solution for the TBM trailer rail rapid transport device, the distance between adjacent load-bearing wheels is less than half the length of the track. Of the two adjacent load-bearing wheels, only one is connected to a gear, and all gears are connected via chain drive. At least one gear is connected to a drive device. This technical solution provides a preferred layout and driving method for the load-bearing wheels. Since the distance between adjacent load-bearing wheels is less than half the length of the track, the track is always supported above at least two load-bearing wheels during use. Therefore, it is not necessary for both adjacent load-bearing wheels to be connected to gears and driven by the chain; only one load-bearing wheel needs to be driven by the chain via a gear, while the other load-bearing wheel can move along the track.

[0011] Based on the above technical solutions, as a preferred technical solution for the TBM trailer-mounted rail rapid transport device, the corrective wheels are arranged vertically, and the load-bearing wheels are arranged horizontally. This technical solution provides the arrangement of the load-bearing wheels and the corrective wheels themselves, as well as the mutual layout relationship between the corrective wheels and the load-bearing wheels. That is, the rotation axis of the load-bearing wheels is arranged horizontally and perpendicular to the transport direction of the track, while the rotation axis of the corrective wheels is arranged vertically and perpendicular to the transport direction of the track. Preferably, the rotation axes of each load-bearing wheel are arranged horizontally, and the height of each load-bearing wheel is the same or decreases sequentially along the transport direction. Preferably, the rotation axes of each corrective wheel are arranged vertically. Of course, the rotation axes of the corrective wheels can also be arranged at an angle, as long as the transport direction of the track during the transport process can be restricted.

[0012] Based on the above technical solutions, as a preferred technical solution for the TBM trailer-mounted rail rapid transport device, the drive device is an electric motor or a hydraulic motor. This technical solution provides two preferred types of drive devices, which can be either electric motors or hydraulic motors, allowing for selection of the type. Those skilled in the art can make a reasonable selection based on economy and practicality under the guidance of this technical concept.

[0013] A trailer includes a trailer platform connected to the TBM trailer track rapid transport device described in any of the above-mentioned technical solutions. The TBM trailer track rapid transport device is arranged along the length of the trailer platform. This technical solution provides a trailer equipped with the aforementioned TBM trailer track rapid transport device. During trailer construction, as the trailer platform moves forward, the rear track can be dismantled and directly transported to the front of the trailer platform via the TBM trailer track rapid transport device. Then, a track for travel can be laid directly in front of the trailer platform. This not only greatly improves the efficiency of trailer track laying but also reduces the labor intensity of construction workers and lowers the safety risks of manual track transport.

[0014] Based on the above technical solutions, as a preferred technical solution for the trailer, the TBM trailer rail rapid transport device is connected to the lower part of the trailer platform. This technical solution provides a preferred layout relationship between the TBM trailer rail rapid transport device and the trailer platform, that is, connecting the TBM trailer rail rapid transport device to the lower part of the trailer platform. This avoids occupying space on the trailer platform, effectively utilizes the unused space under the trailer platform, and, more importantly, reduces the transfer distance of the rail in the vertical direction, further reducing labor intensity. At the same time, it also reduces the height of the rail during transportation, further reducing safety risks.

[0015] Based on the above technical solutions, as a preferred technical solution for the trailer, the load-bearing wheel is connected to the fixed frame via a load-bearing wheel bracket, the fixed frame is connected to the trailer platform, and the steering wheel is connected to the trailer platform via a steering wheel fixing seat. This preferred arrangement of the steering wheel and load-bearing wheel in this technical solution does not change the original structure of the trailer platform; it only requires connecting the fixed frame, i.e., the steering wheel fixing seat, to the lower part of the trailer platform.

[0016] Based on the above technical solution, as a preferred technical solution for the trailer, each of the load-bearing wheels is connected to the trailer platform via a fixing frame. The fixing frame is U-shaped and its upper end is connected to the lower end face of the trailer platform. The steering wheel fixing seat is connected to the lower end face of the trailer platform and is arranged at intervals from the fixing frame. This technical solution provides a preferred structure and arrangement of the fixing frame and the steering wheel fixing seat. The load-bearing wheels use independent fixing frames, and the steering wheels use independent steering wheel fixing seats. This not only facilitates layout, installation, and debugging, allowing for various flexible adjustments, but also facilitates manufacturing, maintenance, and replacement.

[0017] A tunneling machine includes a tunneling host connected to a trailer as described in any of the above technical solutions. The trailer's track can be continuously transported during the tunneling machine's construction process, thereby enabling the trailer to move continuously, reducing downtime during tunneling, and improving the tunneling machine's construction efficiency.

[0018] Compared with existing technologies, the TBM trailer-mounted rail rapid transport device and trailer proposed in this utility model improve rail transport efficiency, reduce the labor intensity of rail transfer, and also improve rail laying efficiency while reducing construction safety risks. Compared with existing trailer-mounted rail transport methods, the technical solution provided by this utility model can quickly meet the on-site rail rapid transport needs of tunnel boring machines / TBM trailers, improve rail transport safety, and achieve convenient and efficient trailer-mounted rail round-trip transport.

[0029] A TBM trailer-mounted rail rapid transport device, such as Figure 1 and Figure 2 As shown, it includes several load-bearing wheels 6 arranged along the rail transport direction. Each load-bearing wheel 6 is used to rotate and transport the rail 1 located above it. On both sides of the load-bearing wheel 6, there are correction wheels 2 for guiding the rail 1.

[0030] This embodiment includes several bearing wheels 6 and several straightening wheels 2. The distance between adjacent bearing wheels 6 is less than the length of a single track 1. Similarly, along the conveying direction, the distance between adjacent straightening wheels 2 is also less than the length of a single track 1. In the left and right directions perpendicular to the conveying direction, the straightening wheels 2 on the left and right sides can be arranged symmetrically or at intervals.

[0031] It should be noted that the bearing wheel 6 can be driven manually or by the drive device 3. The correction wheel 2 can be driven by the drive device 3 or not. During the process of the bearing wheel 6 driving the track 1 for conveying, since the vertical distance between the left and right correction wheels 2 is greater than the width of the track 1, and the height of the top surface of the track 1 is higher than the height of the bottom surface of the correction wheel 2, when the track 1 tilts, the track 1 and the correction wheel 2 come into contact with each other. The correction wheel 2 rotates due to friction, so that the track 1 is always conveyed in the predetermined target direction.

[0032] Based on the above embodiments, as a preferred embodiment of the TBM trailer rail rapid transport device, the distance between adjacent bearing wheels 6 is less than the length of the rail 1, each bearing wheel 6 is connected to a gear 4, each gear 4 is connected by a chain 7, and at least one gear 4 is connected to a drive device 3.

[0033] This embodiment provides a preferred implementation of the drive bearing wheel 6, namely, using a chain drive mechanism. In this chain drive mechanism, only one drive device 3, one chain 7, and a corresponding gear 4 are needed to achieve transmission. Of course, multiple drive devices 3, one chain 7, and a corresponding gear 4 can also be used, but the synchronization of each drive device 3 must be ensured. Alternatively, multiple drive devices 3, multiple chains 7, and corresponding gears 4 can be used, with each drive device 3 corresponding to one chain, and each chain corresponding to one or more gears 4. In this case, it is not necessary to ensure the synchronization of each drive device 3.

[0034] Based on the above embodiments, as a preferred embodiment of the TBM trailer rail rapid transport device, the distance between adjacent bearing wheels 6 is less than half the length of the rail 1. In two adjacent bearing wheels 6, only one bearing wheel 6 is connected to a gear 4. Each gear 4 is connected by a chain 7. At least one gear 4 is connected to a drive device 3.

[0035] This embodiment provides a preferred layout and driving method for the bearing wheels 6. Since the distance between adjacent bearing wheels 6 is less than half the length of the track 1, the track 1 is always supported above at least two bearing wheels 6 during use. Therefore, it is not necessary for both adjacent bearing wheels 6 to be connected to the gear 4 and driven by the chain 7. Only one bearing wheel 6 needs to be driven by the chain 7 through the gear 4, while the other bearing wheel 6 can move to transport the track 1.

[0036] Based on the above embodiments, in a preferred embodiment of the TBM trailer track rapid transport device, the corrective wheel 2 is arranged vertically, and the load-bearing wheel 6 is arranged horizontally. This embodiment provides the arrangement of the load-bearing wheel 6 and the corrective wheel 2 themselves, as well as the mutual layout relationship between the corrective wheel 2 and the load-bearing wheel 6. That is, the rotation axis of the load-bearing wheel 6 is arranged horizontally and perpendicular to the conveying direction of the track 1, while the rotation axis of the corrective wheel 2 is arranged vertically and perpendicular to the conveying direction of the track 1. Preferably, the rotation axes of each load-bearing wheel 6 are arranged horizontally, and the height of each load-bearing wheel 6 is the same or decreases sequentially along the conveying direction. Preferably, the rotation axes of each corrective wheel 2 are arranged vertically. Of course, the rotation axes of the corrective wheel 2 can also be arranged at an angle, as long as the conveying direction of the track 1 during the conveying process can be restricted.

[0037] Based on the above embodiments, in a preferred embodiment of the TBM trailer-mounted rail rapid transport device, the drive device 3 is an electric motor or a hydraulic motor. This embodiment provides two preferred types of drive devices 3, which can be either electric motors or hydraulic motors, allowing for selection based on cost-effectiveness and practicality, guided by this technical concept.

[0038] As a preferred embodiment of the TBM trailer track rapid transport device, a TBM trailer track rapid transport device is proposed to address the shortcomings of the aforementioned background technology, solving the problems of inconvenient installation, disassembly, and transportation of tunnel boring machines / TBM trailer tracks, and heavy reliance on manual handling in the prior art. The core inventive points of this embodiment include: ① on-site functionality for forward transport and directional adjustment; ② convenient installation and disassembly, and short usage time. This embodiment mainly includes the following: The mechanism includes a drive motor, gear 4, a load-bearing wheel 6, a load-bearing wheel bracket 5, a fixed frame 9, a fixed frame base 10, a steering wheel 2, a steering wheel fixing seat 8, and a chain 7. The fixed frame base 10 and the steering wheel fixing seat 8 are welded to the underside of the trailer platform 11. The fixed frame 9 and the steering wheel 2 are connected to their respective fixing seats via bolts and nuts. The load-bearing wheel bracket 5 is welded to the fixed frame 9, and the load-bearing wheel 6 is mounted on the load-bearing wheel bracket 5. The fixed frame 9 and the fixed frame base 10 are welded to a suitable position on the trailer according to the length of the transport track. The drive motor is fixed to one side of the fixed frame 9 and rotates via a shaft connected to the gear 4. The gear 4 is connected to the load-bearing wheel 6 via a shaft, and the chain 7 is mounted on the gear 4. The rotation of the gear 4 drives the rotation of the load-bearing wheel 6. The control valve group is fixed in a suitable position for easy operation. The oil tank provides output force to the transport mechanism, and the pump station provides a certain pressure and flow to the drive motor. The valve group controls the transport speed and direction of the device.

[0039] This device uses a motor to provide driving force, which drives gears and chains to rotate the load-bearing wheels on each fixed frame. The track is placed on the rotating load-bearing wheels and transports the track forward. During operation, the track is always supported by at least two load-bearing wheels to ensure that the track will not fall during transportation. The track can be corrected by a correction wheel during operation to ensure that the track maintains a straight transport.

[0040] Therefore, according to this embodiment, the transportation needs of tracks and sleepers during on-site track extension and laying can be met, and the safety of transportation can be improved, achieving convenient and efficient technical effects and solving the problem of high transportation intensity in existing track extension.

[0041] The specific implementation method is as follows: This device includes: a track 1, a straightening wheel 2, a drive unit 3, a gear 4, a support wheel bracket 5, a support wheel 6, a chain 7, a straightening wheel mounting base 8, and a mounting frame 9. The mounting frame base and the straightening wheel base are welded to the lower part of the trailer platform. The straightening wheel and the mounting frame are connected to the mounting base by bolts. The motor is fixed to one side of the mounting frame, and the motor drive shaft, serving as the drive unit 3, passes through the mounting frame and connects to the gear. The gear drives the support wheel fixed to the mounting frame to rotate. The support wheels are connected by a chain, and the motor provides output force to place the required transport track onto the support wheels for track transport. The straightening wheel assists in adjusting the track's trajectory during track transport, ensuring the track follows the predetermined route. The device has an integrated pump station to provide pressure and flow to the mechanism.

[0042] The steps for using this device are as follows: Step 1: Based on the appropriate placement of the trailer bottom, weld the load-bearing wheel bracket to the fixed frame. Select an appropriate spacing and weld the fixed frame base and the straightening wheel base to the trailer bottom crossbeam to keep the fixed frame and the straightening wheel on the same axis.

[0043] Step 2: Fix the motor to the mounting bracket and secure it with bolts, then connect the gears and the load-bearing wheel.

[0044] Step 3: Install and connect the chain to the gears on the multiple fixed frames.

[0045] Step 4: Connect the oil pipes and valve assembly to the equipment pump station.

[0046] Step 5: Start the pump station and control the oil through the valve group to enter the drive motor for forward and reverse rotation through the pipeline, which in turn drives the gear to rotate and rotate the bearing wheel.

[0047] Step Six: Place the track on the idler rollers and transport it forward or backward through multiple load-bearing wheels. If the track deviates, the correction wheel will keep the track in a straight line, thus achieving the desired transport effect.

The TBM trailer track rapid transport device is arranged along the length of the trailer platform 11. This embodiment provides a trailer equipped with the aforementioned TBM trailer track rapid transport device. During trailer construction, as the trailer platform 11 moves forward, the rear track 1 can be removed and directly transported to the front of the trailer platform 11 via the TBM trailer track rapid transport device. This allows for the direct laying of the track 1 in front of the trailer platform 11, significantly improving the efficiency of track laying, reducing the labor intensity of construction workers, and minimizing the safety risks associated with manually transporting the track 1.

[0049] Based on the above embodiments, as a preferred embodiment of the trailer, the TBM trailer track rapid transport device is connected to the lower part of the trailer platform 11. This embodiment provides a preferred layout relationship between the TBM trailer track rapid transport device and the trailer platform 11, that is, the TBM trailer track rapid transport device is connected to the lower part of the trailer platform 11, which not only avoids occupying space on the trailer platform 11, but also effectively utilizes the unused space under the trailer platform 11. More importantly, it reduces the transfer distance of the track 1 in the vertical direction, further reducing labor intensity, and also reduces the height of the track 1 during the transportation process, further reducing safety risks.
