Description

Technical Field

[0001] This utility model relates to the field of tunnel construction technology, and in particular to a tunnel construction transmission device. Background Technology

[0002] A tunnel boring machine (TBM) is a specialized piece of engineering machinery used in tunnel construction. It can continuously advance along the tunnel's axis while simultaneously excavating the soil. In actual construction, TBMs are usually used in conjunction with a trolley to meet the power requirements for tunneling. The trolley and the TBM are connected by a traction device. When the TBM turns, the trolley is prone to deviation from its trajectory due to inertia and other factors, thus interfering with the energy supply from the trolley to the TBM.

[0003] In related technologies, a traction bar is usually installed between the trolley and the tunnel boring machine. When construction personnel discover that the trolley's trajectory has deviated, they need to adjust the extension length of the traction bar to correct the trolley's position relative to the track inside the tunnel and reduce the trolley's positional deviation. However, in the above adjustment process, whether the trolley's trajectory has deviated depends entirely on the construction personnel's visual judgment, which has large observation errors and strong observation lag. Furthermore, the adjustment length of the traction bar depends on the construction personnel's experience to determine, resulting in poor adjustment accuracy.

[0004] Therefore, there is an urgent need to propose a tunnel construction transmission device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a tunnel construction transmission device that can reduce adjustment lag, reduce adjustment error and improve adjustment accuracy.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] This utility model proposes a tunnel construction transmission device, comprising:

[0008] The main body of the device includes a traveling mechanism, a traction mechanism and a drive mechanism. One end of the traction mechanism is fixedly mounted on the drive mechanism, and the other end is flexibly connected to the traveling mechanism. Both the traveling mechanism and the drive mechanism can be mounted on a preset track in the tunnel. The drive mechanism is used to drive the traveling mechanism to travel along the preset track. A traveling wheel is mounted on the side of the drive mechanism closest to the preset track.

[0009] A spacing measuring device, installed on the traveling wheel, is used to measure the distance between the traveling wheel and the wall of the preset track;

[0010] The control module has its input terminal electrically connected to the spacing measuring device to obtain the measurement data from the spacing measuring device, and its output terminal electrically connected to the traction mechanism to adjust the position of the walking wheel relative to the preset track through the traction mechanism.

[0011] Specifically, the traction mechanism includes a traction component, an adjusting component, and a driving component. One end of the adjusting component is connected to the output end of the driving component, and the other end is retractably connected to the traction component. The traction component is connected to the traveling mechanism, and the driving component is fixedly installed on the driving mechanism.

[0012] More specifically, the adjusting element is a piston rod or a telescopic rod.

[0013] Optionally, at least two traction mechanisms are provided at intervals along the width direction of the drive mechanism, and the at least two traction mechanisms can be symmetrically arranged along the length direction of the preset track.

[0014] Optionally, spacing measuring elements are symmetrically arranged on both sides of the axial direction of the traveling wheel.

[0015] For example, the spacing measuring device is an ultrasonic sensor or a laser sensor.

[0016] Optionally, the tunnel construction transmission device includes at least two drive mechanisms, which are interconnected and can be spaced apart along the length of a preset track.

[0017] Optionally, a shock-absorbing and wear-resistant layer is provided on the outer periphery of the walking wheel.

[0018] The beneficial effects of this utility model are:

[0019] This invention proposes a tunnel construction transmission device. A spacing measuring component is installed on the traveling wheel to measure the distance between the traveling wheel and the preset track wall in real time. Compared to existing technologies where the trajectory deviation of the traveling wheel is observed visually by construction workers, this invention allows construction workers to directly obtain spacing data after the spacing measuring component is installed, facilitating timely adjustment operations and reducing the lag in adjustment operations. One end of the traction mechanism is fixedly mounted on the drive mechanism, and the other end is adjustablely connected to the traveling mechanism, allowing for flexible adjustment of the relative positions of the drive mechanism and the traveling mechanism. The input end of the control module is electrically connected to the spacing measuring component to obtain real-time distance data between the traveling wheel and the preset track wall. When the data measured by the spacing measuring component exceeds a preset deviation, the traction mechanism can be used to perform adjustment work. By adjusting the position of the drive mechanism relative to the traveling mechanism, the distance deviation between the traveling wheel and the preset track is reduced, ensuring the driving stability of the drive mechanism on the traveling mechanism. Compared to relying on manual experience for adjustment, the spacing measuring device, control module and traction mechanism work together to reduce the adjustment error of the construction personnel in the distance between the traveling wheel and the preset track, improve the adjustment accuracy after the traveling wheel deviates from the track, and improve the degree of automation of the adjustment process.

[0030] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0031] like Figures 1-3 As shown, this embodiment provides a tunnel construction transmission device, including a device body 1, a spacing measuring component 2, and a control module. The device body 1 includes a traveling mechanism 11, a traction mechanism 12, and a drive mechanism 13. One end of the traction mechanism 12 is fixedly mounted on the drive mechanism 13, and the other end is adjustablely connected to the traveling mechanism 11. Both the traveling mechanism 11 and the drive mechanism 13 can be mounted on a preset track 31 within the tunnel 3. The drive mechanism 13 drives the traveling mechanism 11 to travel along the preset track 31. A traveling wheel 131 is mounted on the side of the drive mechanism 13 closest to the preset track 31. The spacing measuring component 2 is mounted on the traveling wheel 131 and is used to measure the distance between the traveling wheel 131 and the wall of the preset track 31. The input end of the control module is electrically connected to the spacing measuring component 2 to obtain the measurement data from the spacing measuring component 2. The output end of the control module is electrically connected to the traction mechanism 12 to adjust the position of the traveling wheel 131 relative to the preset track 31. The structure and working principle of the control module are existing technologies and will not be described in detail here. It is understandable that the drive mechanism 13 can not only drive the traveling mechanism 11 to move along the preset track 31, but also move synchronously with the traveling mechanism 11 along the preset track 31 itself, which will not be described in detail hereafter.

[0032] In this embodiment, the spacing measuring device 2 is installed on the traveling wheel 131 to measure the distance between the traveling wheel 131 and the wall of the preset track 31 in real time. Compared with the prior art where the trajectory deviation of the traveling wheel 131 is observed by the naked eye of the construction personnel, the spacing measuring device 2 in this embodiment allows the construction personnel to intuitively obtain the spacing data, facilitating timely adjustment operations and reducing the lag in the adjustment operations. One end of the traction mechanism 12 is fixedly installed on the drive mechanism 13, and the other end is flexibly connected to the traveling mechanism 11, so that the relative position of the drive mechanism 13 and the traveling mechanism 11 can be flexibly adjusted. The input terminal of the control module is electrically connected to the spacing measuring device 2 to obtain the spacing data between the traveling wheel 131 and the wall of the preset track 31 in real time. When the data measured by the spacing measuring device 2 exceeds the preset deviation, the traction mechanism 12 can be used to perform adjustment. By adjusting the position of the drive mechanism 13 relative to the traveling mechanism 11, the spacing deviation between the traveling wheel 131 and the preset track 31 is reduced, thus achieving position adjustment of the traveling wheel 131 relative to the preset track 31 and ensuring the driving stability of the drive mechanism 13 on the traveling mechanism 11. Compared with adjustment relying on manual experience, the coordinated action of the spacing measuring device 2, the control module, and the traction mechanism 12 improves the adjustment accuracy after the traveling wheel 131 deviates from the track, reduces the adjustment error of the construction personnel in adjusting the spacing between the traveling wheel 131 and the preset track 31, and improves the automation of the adjustment process.

[0033] For example, the distance between the traveling wheel 131 and the wall of the preset track 31 can fluctuate within a range of 5cm ± 1cm. When the measurement data received by the control module from the distance measuring device 2 exceeds this range, the traction mechanism 12 needs to be controlled to adjust until the distance between the traveling wheel 131 and the wall of the preset track 31 is maintained within the above range, at which point the adjustment process of the traction mechanism 12 is stopped. The output of the control module can also be electrically connected to a display screen to facilitate construction personnel to intuitively obtain the current distance data, so that construction personnel can intervene in a timely manner when the data continues to fluctuate abnormally, thereby improving the safety and reliability of the tunnel 3 construction operation. The distance measuring device 2 can be an ultrasonic sensor, which is highly adaptable to the construction environment and does not require contact with the wall of the preset track 31 during the measurement process. It can be installed on the traveling wheel 131 through a bracket or clamp, and the measurement results are highly accurate and the installation is highly flexible. The distance measuring device 2 can also be a laser sensor, which has a fast response speed and high measurement accuracy, and can meet the needs of dynamic measurement and long-distance detection. Both ultrasonic sensors and laser sensors are existing technologies, and their structural composition and specific working principles will not be described in detail here.

[0034] Preferably, the walking wheel 131 is symmetrically provided with spacing measuring elements 2 on both sides of its axial direction. The symmetrical arrangement of the spacing measuring elements 2 allows the construction personnel to simultaneously monitor the spacing between both sides of the walking wheel 131 and the wall of the preset track 31, thereby improving the reliability of the measurement data.

[0035] For example, such as Figure 1 and Figure 3 As shown, a spacing measuring element 2 is provided on both the first and second sides of the traveling wheel 131 along the axial direction. When the traveling wheel 131 travels normally along the preset track 31, the elements are symmetrically distributed relative to the preset track 31. The spacing measuring element 2 on the first side of the traveling wheel 131 can measure the distance between the first side of the traveling wheel 131 and the first side wall of the preset track 31, and the spacing measuring element 2 on the second side of the traveling wheel 131 can measure the distance between the second side of the traveling wheel 131 and the second side wall of the preset track 31. Compared to having a spacing measuring element 2 on only one side of the traveling wheel 131, providing two spacing measuring elements 2 improves the accuracy of the measurement results, thereby improving the adjustment accuracy of the subsequent traction mechanism 12 on the position of the drive mechanism 13 relative to the traveling mechanism 11. The spacing measuring elements 2 located on the first and second sides of the traveling wheel 131 can both be ultrasonic sensors or both be laser sensors, or one can be an ultrasonic sensor and the other a laser sensor, further improving measurement accuracy. The outer periphery of the traveling wheel 131 may be provided with a shock-absorbing and wear-resistant layer to reduce the impact of vibration or impact on the distance measuring component 2 during the travel of the drive mechanism 13, and also to weaken the vibration or impact effect on the drive mechanism 13.

[0036] Specifically, the traction mechanism 12 includes a traction component 121, an adjusting component 122, and a driving component 123. One end of the adjusting component 122 is connected to the output end of the driving component 123, and the other end is retractably connected to the traction component 121. The traction component 121 is connected to the traveling mechanism 11, and the driving component 123 is fixedly mounted on the driving mechanism 13. The retractable connection of one end of the adjusting component 122 to the traction component 121 allows for adjustment of the driving mechanism 13 relative to the traveling mechanism 11 when the data measured by the spacing measuring component 2 does not meet the preset measurement data requirements. This adjustment, driven by the driving component 123, adjusts the distance between the traveling wheel and the preset track 31 wall, improving the versatility of the tunnel construction transmission device under different tunnel 3 construction conditions. The traction mechanism 12, comprising the traction component 121, the adjusting component 122, and the driving component 123, is relatively independent, making maintenance and installation relatively easy. For example, the drive component 123 is a linear motor, and the adjusting component 122 is a telescopic rod, to accelerate the response speed of the adjustment process and improve the adjustment efficiency and accuracy. In other embodiments, the drive component 123 can also be a jack, and the adjusting component 122 can be a piston rod, to be suitable for tunnel 3 construction operations that require strong traction or support, and to reduce the overall cost of the traction mechanism 12 compared to electric drive.

[0037] Specifically, at least two traction mechanisms 12 are spaced apart along the width direction of the drive mechanism 13, and the at least two traction mechanisms 12 are symmetrically arranged along the length direction of the preset track 31. In this embodiment, the width direction of the drive mechanism 13 is perpendicular to the length direction of the preset track 31. The arrangement of at least two traction mechanisms 12 at intervals along the width direction of the drive mechanism 13 improves the position adjustment efficiency of the drive mechanism 13 relative to the traveling mechanism 11. The symmetrical arrangement of the at least two traction mechanisms 12 along the length direction of the preset track 31 ensures that the traction effect of the traveling mechanism 11 on the drive mechanism 13 is uniform.

[0038] In other embodiments, a traction mechanism 12 can be provided only on one side of the drive mechanism 13 along the width direction, and a traction member 121 can be provided only on the other side of the drive mechanism 13 symmetrically along the width direction. This reduces the difficulty of adjustment and saves the overall manufacturing cost of the tunnel construction transmission device. For example, as shown... Figures 1-3 As shown, the traveling mechanism 11 along Figure 1 When the travel mechanism 11 turns counterclockwise, the adjusting member 122 retracts, and when the travel mechanism 11 moves along the direction of travel, the adjusting member 122 retracts. Figure 1 When the travel direction turns clockwise, the adjusting component 122 is stretched to limit the large deviation of the traveling wheel 131 relative to the preset track 31.

[0039] In this embodiment, the tunnel construction transmission device includes at least two drive mechanisms 13, which are interconnected and spaced apart along the length of the preset track 31. The presence of at least two drive mechanisms 13 enhances the driving force and load capacity of the tunnel construction transmission device, meeting the construction requirements of large tunnel 3 operations. Compared to a single drive mechanism 13, this avoids the potential disruption of the overall driving process of the tunnel construction transmission device due to the failure of a single drive mechanism 13, thus improving fault tolerance.

[0040] For example, the tunnel construction transmission device can be applied to the excavation operation of tunnel 3. The traveling mechanism 11 is a tunnel boring machine (TBM), and the drive mechanism 13 is a trolley that is matched with the TBM and provides excavation power to the TBM. The tunnel construction transmission device can also be applied to the cross-shaped partition assembly operation inside tunnel 3 after the excavation of tunnel 3 is completed. The traveling mechanism 11 is a forklift used to transport the cross-shaped partition, and the drive mechanism 13 is a trolley equipped with the power supply and control cabinet required for the forklift to travel. The traveling mechanism 11 and the drive mechanism 13 are connected by the traction mechanism 12 in this utility model. The tunnel construction transmission device can also be applied to other construction application scenarios of tunnel 3, which will not be listed here.

[0041] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
