Description

Technical Field

[0001] This application relates to the field of construction beam transportation technology, and in particular to a mobile platform and beam transportation system. Background Technology

[0002] In the field of rail transit engineering, precast T-beams and small box girders are relatively long and have small cross-sections. Before prestressing, the overall longitudinal stiffness of the beams is weak. During the precast production process using a production line, the beams are precast on a moving platform and then moved and transported to various workstations along with the platform. The moving platform is supported on a track on the ground by multiple sets of wheels and travels along the track.

[0003] Due to the aforementioned weakness in beam rigidity, when the beam is transported on the existing mobile platform, uneven tracks can lead to localized issues of excessive or insufficient stress on the beam. Specifically, when a traveling wheel encounters a protrusion on the track, the wheel rises, causing the corresponding area of ​​the mobile platform to lift up that part of the beam, increasing the stress in that area. Conversely, when a traveling wheel encounters a depression on the track, the wheel lowers, reducing the support provided by the mobile platform to that area, thus decreasing the support force on that part of the beam. Excessive or insufficient localized stress on the beam can easily lead to defects such as cracks.

[0004] To prevent beam damage in such situations, existing technologies typically employ the following methods: 1. Reducing the transport speed of the moving platform to ensure smooth movement; 2. Placing cushioning material on the moving platform to minimize localized stress variations in the beam; 3. Inspecting the track surface after beam cracking and repairing any uneven areas. However, these methods all have significant drawbacks: reducing the transport speed of the moving platform decreases beam production and transport efficiency; placing cushioning material separately on the moving platform requires additional steps and carries the risk of material displacement; inspecting the track surface after beam cracking is a reactive measure and cannot completely prevent future cracking; furthermore, manual inspection suffers from low efficiency and potential for missed inspections, while regular manual inspections significantly increase workload. Utility Model Content

[0005] This application provides a mobile platform to solve the problem in the prior art that beams are easily damaged due to local stress changes caused by uneven road surfaces during transport, thereby achieving stable and efficient transport of beams.

[0006] This application also provides a beam transportation system.

[0007] According to a first aspect embodiment of the present application, a movable platform includes:

[0008] The load-bearing mechanism is configured to hold the beam to be transported.

[0009] A walking mechanism is fixedly connected to the supporting mechanism, and the walking mechanism is configured to travel on a preset track;

[0010] A pressure detection mechanism is disposed between the walking mechanism and the bearing mechanism. The pressure detection mechanism is configured to detect the pressure on the walking mechanism to characterize the surface flatness of the preset track.

[0011] According to one embodiment of this application, the walking mechanism includes:

[0012] Wheel box, the wheel box and the load-bearing mechanism are fixedly connected;

[0013] The traveling wheels are mounted on the wheel box and partially protrude from the lower part of the wheel box.

[0014] According to one embodiment of this application, the wheel box has a recessed area on the side facing the bearing mechanism, and the bearing mechanism covers the opening of the recessed area so that the wheel box and the bearing mechanism form a closed receiving cavity in the recessed area;

[0015] The pressure detection mechanism is located in the receiving cavity.

[0016] According to one embodiment of this application, the pressure detection mechanism includes an annular pressure detection unit;

[0017] The bearing mechanism has a central shaft on the side facing the wheel box, the central shaft extends into the receiving cavity and passes through the annular pressure detection unit.

[0018] According to one embodiment of this application, the bottom wall of the recessed area is provided with a first fixing hole, and the central shaft passes through the first fixing hole.

[0019] According to one embodiment of this application, the bearing mechanism is provided with a connecting plate on the side facing the wheel box, the wheel box is fixedly mounted on the connecting plate, and the central shaft is disposed on the connecting plate.

[0020] According to one embodiment of this application, the central shaft is a stepped shaft, one end of the pressure detection mechanism abuts against the stepped surface of the central shaft, and the other end abuts against the bottom wall of the recessed area;

[0021] An isolation gap is provided between the connecting plate and the wheel box.

[0022] According to one embodiment of this application, the wheel box is provided with a flange parallel to the bearing mechanism, the flange is provided with a second fixing hole, the connecting plate is provided with a mating hole, and the fastener passes through the second fixing hole and the mating hole to fix the wheel box on the connecting plate.

[0027] The above-described one or more technical solutions in the embodiments of this application have at least one of the following technical effects:

[0028] The movable platform in this application incorporates a pressure detection mechanism between the load-bearing mechanism and the traveling mechanism. This mechanism detects the pressure exerted on the traveling mechanism, allowing for the identification of the track surface condition (protrusions, pits, etc.). This promptly alerts relevant personnel to repair the track, preventing bumps during the platform's movement or sudden changes in localized stress on the beam. This fundamentally solves the problem of beam damage caused by uneven track surfaces during transport. The aforementioned structure enables automated monitoring of the track surface, eliminating the need for manual, periodic inspections. It offers high monitoring accuracy, real-time performance, and eliminates the risk of missed or false detections. Furthermore, this application avoids complex image recognition mechanisms; the pressure detected by the pressure detection mechanism alone is sufficient to characterize the track surface's smoothness, making it highly practical.

[0041] In existing technologies, the tracks of mobile platforms may settle or deform after prolonged operation, potentially causing cracks in the beams to be transported during the platform's movement. During production, manual inspection and adjustment of the tracks are only conducted after beam cracking is observed. However, manually re-measuring all tracks periodically to monitor straightness presents challenges due to the large workload, potential for missed inspections due to human error, and low inspection frequency, making it impossible to effectively monitor track settlement and deformation.

[0042] A movable platform according to an embodiment of the first aspect of this application, such as Figures 1 to 3As shown, the mobile platform includes a bearing mechanism 1, a traveling mechanism 2, and a pressure detection mechanism 3. The bearing mechanism 1 and the traveling mechanism 2 are fixedly connected. The bearing mechanism 1 is configured to place the beam to be transported. The traveling mechanism 2 is configured to travel on a preset track 4. A pressure detection mechanism 3 is provided between the traveling mechanism 2 and the bearing mechanism 1. The pressure detection mechanism 3 is configured to detect the pressure on the traveling mechanism 2 to characterize the surface condition of the preset track 4.

[0043] The supporting mechanism 1 can be a flat plate structure (i.e., a support plate) to facilitate the placement of the beam to be transported. The traveling mechanism 2 is installed below the supporting mechanism 1, supporting the moving platform and enabling it to move forward. A pressure detection mechanism 3 is located between the lower surface of the supporting mechanism 1 and the upper surface of the traveling mechanism 2 to detect the reaction force exerted by the surface of the track 4 on the traveling mechanism 2. Based on the pressure changes detected by the pressure detection mechanism 3, protrusions, settlements, or deformation points on the surface of the track 4 can be identified, allowing relevant personnel to promptly repair the surface of the track 4 and ensure smooth transportation of the moving platform on the track 4.

[0044] The mobile platform in this application can simultaneously inspect the surface condition of track 4 during the transport of the beam, without waiting for the mobile platform to be in a non-working state, thus providing greater real-time performance. This application eliminates the need for a separate inspection device; track inspection can be completed during normal operation of the transport device (i.e., the mobile platform), offering significant advantages compared to using a separate inspection mechanism.

[0045] The movable platform in this application includes a pressure detection mechanism 3 between the bearing mechanism 1 and the traveling mechanism 2. This mechanism detects the pressure exerted on the traveling mechanism 2, allowing for the identification of the surface condition of the track 4. (When the track 4 is partially concave, the pressure on the traveling mechanism 2 decreases, and the pressure value detected by the pressure detection mechanism 3 decreases; when the track 4 is partially convex, the pressure on the traveling mechanism 2 increases, and the pressure value detected by the pressure detection mechanism 3 increases.) This promptly alerts relevant personnel to repair the track 4, preventing the movable platform from bumping along the track 4 or causing sudden changes in local stress on the beam. This fundamentally solves the problem of beam damage caused by uneven track 4 surfaces during transport. The above structure enables automated monitoring of the track 4 surface, eliminating the need for manual operation and periodic inspections. It offers high monitoring accuracy, strong real-time performance, and eliminates the risk of missed or false detections. This application does not require complex image recognition mechanisms; the pressure detected by the pressure detection mechanism 3 alone is sufficient to characterize the flatness of the track 4 surface, making it highly practical.

[0046] According to one embodiment of this application, such as Figure 2 and Figure 3As shown, the walking mechanism 2 includes a wheel box 21 and a walking wheel 22. The walking wheel 22 is installed on the wheel box 21 and partially protrudes from the lower part of the wheel box 21; the bearing mechanism 1 and the wheel box 21 are fixedly connected.

[0047] The rigid connection between the traveling mechanism 2 and the load-bearing mechanism 1 achieves high efficiency in load transfer and smooth movement: the traveling wheel 22 partially protrudes from the lower part of the wheel box 21, ensuring direct contact with the track 4. The wheel box 21, as a relatively enclosed shell, protects the bearings of the traveling wheel 22 and related transmission components from dust and water corrosion, extending their service life. The load-bearing mechanism 1 is fixedly connected to the wheel box 21, forming a rigid support system that evenly distributes the beam load and avoids localized stress concentration. The traveling mechanism 2 is installed independently, facilitating future maintenance and replacement.

[0048] According to one embodiment of this application, such as Figure 3 As shown, the wheel box 21 has a recessed area on the side facing the bearing mechanism 1, and the bearing mechanism 1 covers the opening of the recessed area so that the wheel box 21 and the bearing mechanism 1 form a closed receiving cavity 213 in the recessed area; the pressure detection mechanism 3 is disposed in the receiving cavity 213.

[0049] The recessed area of ​​the wheel box 21 and the supporting mechanism 1 form a closed receiving cavity 213. The enclosing design of the recessed area and the supporting mechanism 1 constitutes a rigid protective structure, which can isolate the pressure detection mechanism 3 from interference by dust, water, debris and mechanical impact, ensuring the long-term stable operation of the pressure detection mechanism 3. The pressure detection mechanism 3 is set in the receiving cavity 213, so that the detection component can directly receive the pressure changes of the walking mechanism 2, improving the real-time performance and accuracy of pressure monitoring. This structure uses spatial nesting to achieve hidden installation of components, which does not increase the overall height of the moving platform, avoids collision damage caused by exposed detection devices, and facilitates later sealing and maintenance.

[0050] According to one embodiment of this application, such as Figure 3 As shown, the pressure detection mechanism 3 includes an annular pressure detection unit 31; a central shaft 12 is provided on the side of the bearing mechanism 1 facing the wheel box 21, the central shaft 12 extends into the receiving cavity 213 and passes through the annular pressure detection unit 31. The pressure detection unit 31 can be a pressure sensor.

[0051] The coaxial design of the central shaft 12 and the annular pressure detection unit 31 forms a symmetrical load transmission path: the central shaft 12 passes through the annular unit (i.e., the annular pressure detection unit 31), allowing the pressure to be transmitted vertically along the axis. Utilizing the anti-lateral force characteristics of the annular structure, measurement deviations caused by eccentric loads are eliminated, improving detection accuracy. Furthermore, the central shaft 12 acts as a mechanical limiter for the pressure detection unit 31, preventing displacement during operation and ensuring long-term stable operation of the sensor.

[0052] The central shaft 12 can be configured as a hollow shaft to facilitate the internal installation of wires. For example, the pressure signal collected in real time by the pressure detection unit 31 can be transmitted to the main control system via the cable built into the central shaft 12. The main control system collects and displays the pressure data during the movement of the moving platform in real time, and can accurately detect protrusions or pits larger than 0.5mm on the surface of the track 4 (determined by the pressure change threshold), providing data support for early warning of the track 4 status during beam transportation. Of course, the wires can also be arranged in other locations as needed.

[0053] According to one embodiment of this application, such as Figure 3 As shown, the bottom wall of the recessed area is provided with a first fixing hole 215, and the central shaft 12 passes through the first fixing hole 215.

[0054] A first fixing hole 215 is provided on the bottom wall of the recessed area, and the central shaft 12 extends through the first fixing hole 215 to achieve precise mechanical positioning and optimized load transmission path. The through-hole design of the first fixing hole 215 and the central shaft 12 prevents relative displacement between the wheel box 21 and the bearing mechanism 1, ensuring that the moving platform is flat and operates reliably. The hole diameter tolerance (e.g., H7 / g6 fit) and surface roughness (e.g., Ra≤1.6μm) of the fixing hole can be precisely designed according to the load level to adapt to different pressure detection units 31, improving versatility.

[0055] A mounting cavity is also provided at the lower part of the wheel box 21, and the traveling wheel 22 is installed in the mounting cavity of the wheel box 21. The end of the central shaft 12 extends into the mounting cavity through the first fixing hole 215. The length of the central shaft 12 extending into the mounting cavity can be adjusted according to actual needs.

[0056] A sealing ring can be installed in the first fixing hole 215 to prevent dust or water from entering the receiving cavity 213 due to the gap between the central shaft 12 and the first fixing hole 215, and to ensure that the pressure detection mechanism 3 in the receiving cavity 213 is not affected by dust or water.

[0057] According to one embodiment of this application, such as Figure 3 As shown, a connecting plate 11 is provided on the side of the bearing mechanism 1 facing the wheel box 21, the wheel box 21 is fixedly installed on the connecting plate 11, and the central shaft 12 is provided on the connecting plate 11.

[0058] The connecting plate 11, as an intermediate load-bearing component, is fixedly installed on the lower surface of the load-bearing mechanism 1 to improve the strength of the connection between the load-bearing mechanism 1 and the wheel box 21 and avoid the problem of easy cracking at the connection.

[0059] In practical applications, the flatness of the connecting plate 11 can be improved separately to enhance the installation accuracy of the wheel box 21 (e.g., flatness error ≤ 0.1 mm / m). This ensures that the upper surface of the annular pressure detection unit 31 makes stable contact with the connecting plate 11, preventing excessive force on one side of the upper surface of the annular pressure detection unit 31 while the other side fails to contact the connecting plate 11. Improving the flatness of the connecting plate 11 separately eliminates the need to process the entire lower surface of the bearing mechanism 1, thus reducing manufacturing costs to some extent.

[0060] The connecting plate 11 is fixed to the lower surface of the bearing mechanism 1 by means of welding or bolt connection.

[0061] According to one embodiment of this application, such as Figure 3 As shown, the central shaft 12 is a stepped shaft. One end of the pressure detection mechanism 3 abuts against the stepped surface 121 (shoulder) of the central shaft 12, and the other end abuts against the bottom wall of the recessed area. An isolation gap is provided between the connecting plate 11 and the wheel box 21. The isolation gap prevents the wheel box 21 from contacting the connecting plate 11, thus avoiding affecting the normal force bearing of the pressure detection mechanism 3. The pressure detection mechanism 3 is a rigid component that directly bears the weight of the bearing mechanism 1 and the beam to be transported, and will not deform.

[0062] Of course, in some cases, one end of the pressure testing mechanism 3 can also directly abut against the connecting plate 11.

[0063] By setting an isolation gap between the connecting plate 11 and the wheel box 21, an interference-free load transmission path is formed: the two ends of the pressure detection mechanism 3 are rigidly in contact with the stepped surface 121 of the central shaft 12 and the bottom wall of the concave area, respectively, directly bearing the vertical load (including static load and dynamic impact) of the bearing mechanism 1 and the beam to be transported. The isolation gap (e.g., 2-5mm) between the connecting plate 11 and the wheel box 21 completely cuts off the mechanical contact between the two, ensuring that the pressure signal is generated only by the pressure change caused by the undulation of the track 4 surface. The setting of the isolation gap also provides space for the slight sway of the wheel box 21 (e.g., ±1° tilt when the traveling wheel 22 passes through the joint of the track 4), ensuring that when traveling on the track 4 with a slope, the wheel box 21 will not contact the connecting plate 11, avoiding affecting the pressure detection of the pressure detection mechanism 3.

[0064] In practical applications, sealing material can be placed in the isolation gap to prevent external dust and water from entering the receiving cavity 213, thus avoiding external interference with the pressure detection mechanism 3 within the receiving cavity 213. The sealing material can be made of a material with high elasticity to reduce the pressure it bears and prevent interference with the normal pressure detection of the pressure detection mechanism 3.

[0065] According to one embodiment of this application, such as Figure 3As shown, the wheel box 21 is provided with a flange 214 parallel to the bearing mechanism 1. The flange 214 is provided with a second fixing hole 216. The connecting plate 11 is provided with a mating hole 13. The fastener 217 passes through the second fixing hole 216 and the mating hole 13 to fix the wheel box 21 on the connecting plate 11.

[0066] The connecting plate 11 is fitted to the bearing mechanism 1. The second fixing hole 216 here can actually penetrate the lower wall of the bearing mechanism 1 and the connecting plate 11, such as... Figure 3 As shown.

[0067] The wheel box 21 flange 214 is connected to the connecting plate 11 by a fastener 217. Combined with the aforementioned "central shaft 12 passes through the first fixing hole 215 and extends into the mounting cavity", a reliable connection between the wheel box 21 and the bearing mechanism 1 is achieved, ensuring that there will be no relative displacement between the wheel box 21 and the bearing mechanism 1 during the forward movement of the moving platform. Furthermore, the above connection method only constrains the horizontal direction and does not constrain the vertical direction, ensuring that the normal vertical force of the pressure detection mechanism 3 will not be affected.

[0068] The flange 214 serves as an extension of the load-bearing structure of the wheel box 21 and does not affect the arrangement of the internal accommodating cavity 213 (and the subsequent first damping cavity 211 and second damping cavity 212) of the wheel box 21.

[0069] In practical applications, the thickness at the flange 214 can be increased to improve the strength at that point.

[0070] The detachable connection between the flange 214 and the connecting plate 11 enables quick replacement of the wheel box 21 assembly, significantly improving equipment maintainability.

[0071] The fastener 217 can be a stepped bolt. The step length of the stepped bolt is greater than the thickness of the flange 214 of the wheel box 21, the thickness of the bearing mechanism 1 and the connecting plate 11, and the total of the reserved gap. This ensures that when the bolt is tightened, the wheel box 21 is in a free state in the vertical direction, thereby ensuring that the pressure ring can accurately detect the vertical load of the wheel box 21. Of course, it can also be tightened with a nut.

[0072] According to one embodiment of this application, such as Figure 3 As shown, along the traveling direction of the movable platform, the wheel box 21 also includes a first damping cavity 211 located in front of the receiving cavity 213 and a second damping cavity 212 located behind the receiving cavity 213.

[0073] The wheel box 21 features a structural design with a first damping cavity 211 and a second damping cavity 212 positioned before and after the receiving cavity 213. Through a layout of "front and rear double buffers + central rigid detection," a composite system for graded absorption of impact energy and stable load transmission is constructed: the first damping cavity 211 at the front can preferentially attenuate the front-end impact during the movement of the moving platform (such as the head-on impact of the protrusion of track 4), while the second damping cavity 212 at the rear absorbs braking inertial force or rear-end bump energy, forming a bidirectional dynamic buffer. This significantly reduces the instantaneous stress in the connection area of ​​the flange 214, preventing fatigue fracture at the edge of the wheel box 21 (i.e., flange 214) caused by high-frequency impacts. The spatial isolation design between the first damping cavity 211, the second damping cavity 212, and the receiving cavity 213 ensures that the vertical load transmission path of the pressure detection mechanism 3 is not affected by the buffer structure.

[0074] For example, elastic elements such as springs or rubber blocks (not shown in the figure) may be further provided in the first damping cavity 211 and the second damping cavity 212, so that the impact energy can be dissipated laterally or vertically through the elastic elements in the damping cavity.

[0075] According to one embodiment of this application, the movable platform further includes a station detection mechanism, which is disposed on the traveling mechanism to obtain the position of the movable platform.

[0076] The mobile platform provided in this application can also integrate a workstation detection mechanism to achieve workstation detection functionality: by monitoring the workstation (real-time position) where the mobile platform is located, and in conjunction with data collected by pressure sensors, the pressure data is correlated with the workstation. When abnormal pressure data occurs, the system reports the workstation where the abnormal data occurred. After detecting abnormal data, the system issues an alarm, indicating the workstation where the abnormal data occurred. Then, the mobile platform passes through the workstation again, observes the real-time pressure data, and pinpoints the exact location where the abnormal data occurred, thereby detecting and locating the settlement and deformation of track 4.

[0077] After acquiring pressure data, the control system simultaneously integrates it with station detection information, binding the pressure data to the corresponding station to form a "pressure-station" mapping relationship. Simultaneously, the control system displays the pressure data in real-time via a human-machine interface (HMI) in the form of curves, allowing operators to monitor pressure changes as the platform moves. The system pre-sets a pressure threshold (±10% of the normal range) to determine if the pressure data is normal. When the measured pressure data exceeds the preset threshold, the system determines it as abnormal, triggering an audible and visual alarm and clearly displaying the corresponding station information on the HMI, such as "Station 3 Pressure Exceeds Standard," promptly alerting the operator to the abnormality. After an anomaly occurs, the moving platform can re-pass through the abnormal station, continuously collecting pressure data during the second movement. By comparing the initial and secondary data collection, combined with real-time monitoring results, the anomaly range is gradually narrowed down, ultimately pinpointing the precise location of the pressure anomaly, such as a settlement or deformation point on a section of the track, thus achieving the detection and location of track settlement and deformation points.

[0078] The working detection mechanism can be a sensor (infrared ranging sensor) or a positioning device (RFID, encoder, GPS, etc.). For example, RFID tags (storing unique ID and coordinate information) are pre-embedded every 1m on both sides of the track, and an RFID reader is installed on the wheel box 21 (reading distance 0.1-0.5m). The preset coordinates are queried by reading the tag ID to realize position detection.

[0079] According to one embodiment of this application, such as Figure 1 and Figure 2 As shown, there are multiple walking mechanisms 2, and at least one walking mechanism 2 and the bearing mechanism 1 are provided with a pressure detection mechanism 3.

[0080] like Figure 1 and Figure 2 As shown, the walking mechanism 2 can be set up in 5 groups in the front and back, with 1 on each side of each group, that is, a total of 10 walking mechanisms 2. Figure 1 and Figure 2 As shown, a pressure detection mechanism 3 is provided between a walking mechanism 2 and a load-bearing mechanism 1, that is, the number of pressure detection mechanisms 3 is 1.

[0081] The multiple configurations of the walking mechanism 2 and the selective deployment of the pressure detection mechanism 3 construct an intelligent transportation system of "distributed load bearing + key point monitoring": multiple walking mechanisms 2 reduce the risk of single-wheel overload by evenly distributing the load. The setting of at least one pressure detection mechanism 3 can achieve accurate monitoring of the entire area of ​​track 4, effectively controlling costs.

[0082] In practical applications, two sets of pressure detection mechanisms 3 can be set up, which takes into account both cost issues and avoids false detections by a single pressure detection mechanism 3.

[0083] The mobile platform provided in this application, by adding a pressure sensor to the traveling mechanism 2, can monitor the overall straightness of the track 4 during the operation of the mobile platform by monitoring the wheel pressure, thus achieving automatic detection of the straightness of the track 4. Each operation of the mobile platform performs a check on all positions along the entire length of the track 4, achieving full-range detection of the track 4 with a high detection frequency and full coverage, ensuring no missed detections. A pressure deviation range can be preset in the control system to provide early warning when the straightness deviation of the track 4 exceeds the limit. The wheel box 21 is connected to the bearing mechanism 1 via a central shaft 12 and stepped bolts. The pressure sensor adopts the form of a pressure ring, ensuring the connection between the wheel box 21 and the bearing mechanism 1 is stable, allowing the wheel box 21 to be in a free state in the vertical direction, thereby accurately measuring the pressure borne by the wheel box 21.

[0084] According to a second aspect of this application, a beam transport system includes the aforementioned movable platform.
