Description

Technical Field

[0001] The present application relates to the technical field of construction beam transportation, and in particular to a mobile platform and beam transportation system. Background Art

[0002] In rail transit engineering, prefabricated T-beams and small box beams are long and small in cross-section. Before prestressing the steel strands, the beams' overall longitudinal stiffness is relatively weak. During production, the beams are prefabricated on a mobile pedestal and then transported between various workstations. The mobile pedestal is supported by multiple sets of running wheels on a track on the ground, along which it travels.

[0003] Due to the aforementioned weak rigidity of the beam, when the beam is placed on an existing mobile platform for transportation, the uneven track can cause the beam to be subjected to localized excessive or insufficient force. Specifically, when a wheel encounters a bump on the track, the wheel is raised, and the corresponding position of the mobile platform lifts the beam, increasing the force applied to that part of the beam. When a wheel encounters a pit on the track, the wheel is lowered, reducing the support provided by the mobile platform to the beam, reducing the support force applied to that part of the beam. Excessive or insufficient force applied to the beam can easily cause defects such as cracks in the beam.

[0004] In this case, the existing technology usually adopts the following methods to avoid damage to the beam: 1. Reduce the transportation speed of the mobile platform to make the mobile platform move as smoothly as possible; 2. Place buffer materials on the mobile platform to reduce the local force variation range of the beam; 3. After the beam cracks, inspect the track surface and repair the unevenness of the track surface. However, the above methods all have major problems: reducing the transportation speed of the mobile platform will reduce the production and transportation efficiency of the beam; placing buffer materials separately on the mobile platform requires additional processes and there is a possibility of buffer material displacement; inspecting the track surface after the beam cracks is a post-remedial measure and still cannot completely avoid the beam cracking. In addition, manual inspection has low detection efficiency and missed detection, and regular manual inspection will greatly increase the manual workload. Summary of the Invention

[0005] The present application provides a mobile platform to solve the problem in the prior art that when transporting a beam, the beam is easily damaged due to local force changes caused by uneven road surface, thereby realizing smooth and efficient transportation of the beam.

[0006] The present application also provides a beam transportation system.

In addition, those skilled in the art can combine and combine different embodiments or examples described in this specification and the features of different embodiments or examples, unless they are contradictory.

[0031] Existing mobile platforms, after prolonged operation, can experience track settlement and deformation, potentially leading to cracking in the beams being transported (hereinafter referred to as beams). During production, manual inspection and adjustment of the tracks are only performed after beam cracking is observed. However, manually retesting the entire track periodically to monitor track straightness presents significant workload, potential for missed inspections due to human error, and infrequent inspections, making effective monitoring of track settlement and deformation impossible.

[0032] According to a first aspect of the present application, a mobile stand is Figures 1 to 3 As shown, the mobile platform includes a supporting mechanism 1, a traveling mechanism 2 and a pressure detection mechanism 3. The supporting mechanism 1 and the traveling mechanism 2 are fixedly connected. The supporting 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 supporting mechanism 1, and the pressure detection mechanism 3 is configured to detect the pressure exerted on the traveling mechanism 2 to characterize the surface condition of the preset track 4.

[0033] The supporting mechanism 1 can be a flat plate structure (i.e., a load plate) to facilitate the placement of the beam to be transported. The traveling mechanism 2 is installed below the supporting mechanism 1, supporting the mobile platform and enabling it to move forward. The pressure detection mechanism 3 is disposed between the lower surface of the supporting mechanism 1 and the upper surface of the traveling mechanism 2 to detect the reaction force of the track 4 surface on the traveling mechanism 2. Based on the changes in the pressure value detected by the pressure detection mechanism 3, the presence of protrusions, subsidence, 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 that the mobile platform can be transported smoothly on the track 4.

[0034] The mobile platform in this application can simultaneously detect the surface condition of the track 4 during the process of transporting the beam, eliminating the need to wait for the mobile platform to be in an inoperative state to perform track 4 inspection, resulting in greater real-time performance. This application eliminates the need for a separate inspection device for inspection; the track inspection can be completed during the normal operation of the transport device (i.e., the mobile platform), offering significant advantages over requiring a separate inspection mechanism for track inspection.

[0035] The mobile platform in this application is provided with a pressure detection mechanism 3 between the supporting mechanism 1 and the traveling mechanism 2 to detect the pressure exerted on the traveling mechanism 2. Based on the pressure exerted on the traveling mechanism 2, the surface condition of the track 4 can be identified (when the track 4 is partially concave, the pressure exerted on the traveling mechanism 2 will decrease, and the pressure value detected by the pressure detection mechanism 3 will decrease; when the track 4 is partially convex, the pressure exerted on the traveling mechanism 2 will increase, and the pressure value detected by the pressure detection mechanism 3 will increase), so that relevant personnel are promptly reminded to repair the track 4, and the mobile platform is prevented from causing bumps when traveling on the track 4 or causing sudden changes in the local force on the beam body. This fundamentally solves the problem that the beam body is easily damaged due to the uneven surface of the track 4 during transportation. The above structure can realize automatic monitoring of the surface of the track 4, without the need for manual operation of instruments for regular inspections. The monitoring has high accuracy and strong real-time performance, and there will be no missed detection or false detection. In this application, there is no need to set up a complex image recognition mechanism. The flatness of the surface of the track 4 can be characterized only by the pressure detected by the pressure detection mechanism 3, which is highly practical.

[0036] According to one embodiment of the present application, Figure 2 and Figure 3 As shown, the traveling mechanism 2 includes a wheel box 21 and traveling wheels 22 . The traveling wheels 22 are installed in the wheel box 21 and partially exposed at the bottom of the wheel box 21 . The supporting mechanism 1 and the wheel box 21 are fixedly connected.

[0037] The rigid connection between the traveling mechanism 2 and the supporting mechanism 1 ensures efficient load transfer and smooth movement. The traveling wheels 22 partially protrude from the underside of the wheel box 21, ensuring direct contact with the rails 4. The wheel box 21, as a relatively enclosed housing, protects the bearings and associated transmission components of the traveling wheels 22 from dust and water erosion, extending their service life. The supporting mechanism 1 and wheel box 21 are fixedly connected to form a rigid support system, evenly distributing the beam load and avoiding localized stress concentrations. The traveling mechanism 2 is installed independently, facilitating subsequent maintenance and replacement.

[0038] According to one embodiment of the present application, Figure 3 As shown, a concave area is provided on the side of the wheel box 21 facing the supporting mechanism 1, and the supporting mechanism 1 covers the opening of the concave area so that the wheel box 21 and the supporting mechanism 1 form a closed accommodating cavity 213 at the concave area; the pressure detection mechanism 3 is arranged in the accommodating cavity 213.

[0039] The concave area of ​​the wheel box 21 and the supporting mechanism 1 form a closed accommodating chamber 213. The encapsulated design of the concave area and the supporting mechanism 1 constitutes a rigid protective structure, which can isolate the pressure detection mechanism 3 from interference from dust, water, debris, and mechanical impact, ensuring the long-term stable operation of the pressure detection mechanism 3. The pressure detection mechanism 3 is arranged in the accommodating chamber 213, so that the detection component directly receives the pressure changes of the traveling mechanism 2, improving the real-time performance and accuracy of pressure monitoring. This structure uses spatial nesting to achieve hidden component installation, which neither increases the overall height of the mobile platform nor avoids collision damage caused by exposed detection devices. It also facilitates subsequent sealing and maintenance.

[0040] According to one embodiment of the present application, 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 support mechanism 1 facing the wheel box 21. The central shaft 12 extends into the accommodating cavity 213 and passes through the annular pressure detection unit 31. The pressure detection unit 31 may be a pressure sensor.

[0041] The coaxial design of the central shaft 12 and the annular pressure detection unit 31 creates a symmetrical load transmission path: the annular unit (i.e., the annular pressure detection unit 31) passes through the central shaft 12, allowing pressure to be transmitted vertically along the axis. The annular structure's ability to resist lateral forces eliminates measurement deviations caused by eccentric loads, improving detection accuracy. Furthermore, the central shaft 12 acts as a mechanical limiter for the pressure detection unit 31, preventing it from shifting during operation and ensuring the long-term stable operation of the sensor.

[0042] The central shaft 12 can be configured as a hollow shaft as needed to facilitate the routing of wires. For example, the pressure signal collected in real time by the pressure detection unit 31 is 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 mobile platform in real time. It can accurately detect any bumps or pits larger than 0.5 mm on the surface of the track 4 (determined by a pressure mutation 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.

[0043] According to one embodiment of the present application, Figure 3 As shown, a first fixing hole 215 is provided on the bottom wall of the concave area, and the central shaft 12 passes through the first fixing hole 215 .

[0044] A first fixing hole 215 is provided in the bottom wall of the recessed area, and the central shaft 12 extends through this hole, enabling precise mechanical positioning and optimizing the load transfer path. The placement of the first fixing hole 215 and the central shaft 12 prevents relative displacement between the wheel box 21 and the support mechanism 1, ensuring smooth and reliable operation of the mobile platform. The fixing hole's aperture tolerance (e.g., H7 / g6 fit) and surface roughness (e.g., Ra ≤ 1.6μm) can be precisely designed based on load levels to accommodate different pressure detection units 31, enhancing versatility.

[0045] A mounting cavity is also provided below the wheel housing 21, into which the running wheel 22 is mounted. The end of the central shaft 12 extends through the first fixing hole 215 and into the mounting cavity. The length of the central shaft 12 extending into the mounting cavity can be adjusted according to actual needs.

[0046] A sealing ring may be provided in the first fixing hole 215 to prevent a gap between the central shaft 12 and the first fixing hole 215 from causing dust or water to enter the accommodating cavity 213 , thereby ensuring that the pressure detection mechanism 3 in the accommodating cavity 213 is not affected by dust or water.

[0047] According to one embodiment of the present application, Figure 3 As shown, a connecting plate 11 is provided on a side of the supporting mechanism 1 facing the wheel box 21 , the wheel box 21 is fixedly mounted on the connecting plate 11 , and the central shaft 12 is provided on the connecting plate 11 .

[0048] The connecting plate 11 serves as an intermediate load-bearing component and is fixedly mounted on the lower surface of the supporting mechanism 1 to improve the strength of the connection between the supporting mechanism 1 and the wheel box 21 and avoid the problem of cracking of the connection.

[0049] In actual use, the flatness of the connecting plate 11 can be individually improved to enhance the installation accuracy of the wheel box 21 (e.g., a flatness error of ≤0.1 mm / m). This ensures that the upper surface of the annular pressure detection unit 31 is in stable contact with the connecting plate 11, thus avoiding the problem of excessive force on one side of the upper surface of the annular pressure detection unit 31 and loss of contact with the connecting plate 11 on the other side. Improving the flatness of the connecting plate 11 alone eliminates the need to machine the entire lower surface of the support mechanism 1, thus reducing manufacturing costs to a certain extent.

[0050] The connecting plate 11 is fixed to the lower surface of the supporting mechanism 1 by welding or bolt connection.

[0051] According to one embodiment of the present application, Figure 3As shown, the central shaft 12 is a stepped shaft. One end of the pressure detection mechanism 3 abuts against the stepped surface 121 (shaft shoulder) of the central shaft 12, and the other end abuts against the bottom wall of the concave area. An isolation gap is provided between the connecting plate 11 and the wheel box 21. This isolation gap prevents contact between the wheel box 21 and the connecting plate 11, thus preventing any impact on the normal load of the pressure detection mechanism 3. The pressure detection mechanism 3 is a rigid component that directly bears the weight of the load-bearing mechanism 1 and the beam to be transported, without deformation.

[0052] Of course, in some cases, one end of the pressure detection mechanism 3 may also directly abut against the connecting plate 11 .

[0053] By providing an isolation gap to separate the connecting plate 11 and the wheel box 21, an interference-free load transfer path is formed: the two ends of the pressure detection mechanism 3 are rigidly abutted against the stepped surface 121 of the central axis 12 and the bottom wall of the concave area, respectively, directly bearing the vertical load (including static load and dynamic impact) of the load-bearing mechanism 1 and the beam to be transported. The isolation gap (e.g., 2-5 mm) between the connecting plate 11 and the wheel box 21 completely cuts off the mechanical contact between them, ensuring that the pressure signal is generated solely by pressure changes caused by the undulations of the track 4 surface. The provision of the isolation gap also provides space for slight swings of the wheel box 21 (such as the ±1° tilt when the running wheel 22 passes through the joint of the track 4), ensuring that when traveling on a sloped track 4, the wheel box 21 will not come into contact with the connecting plate 11, thereby avoiding affecting the pressure detection of the pressure detection mechanism 3.

[0054] In practical applications, a sealing material may be placed in the isolation gap to prevent external dust and water from entering the accommodating chamber 213, thereby preventing external interference with the pressure detection mechanism 3 in the accommodating chamber 213. The sealing material may be made of a material with high elasticity to reduce the pressure on the sealing material and avoid interference with the normal pressure detection of the pressure detection mechanism 3.

[0055] According to one embodiment of the present application, Figure 3 As shown, the wheel box 21 is provided with a flange 214 parallel to the supporting mechanism 1, the flange 214 is provided with a second fixing hole 216, the connecting plate 11 is provided with a matching hole 13, and the fixing member 217 passes through the second fixing hole 216 and the matching hole 13 to fix the wheel box 21 on the connecting plate 11.

[0056] The connecting plate 11 is arranged in close contact with the supporting mechanism 1. The second fixing hole 216 here can actually pass through the lower wall of the supporting mechanism 1 and the connecting plate 11. Figure 3 shown.

[0057] The flange 214 of the wheel box 21 is connected to the connecting plate 11 through a fixing part 217. Combined with the aforementioned "center axis 12 passes through the first fixing hole 215 and extends into the installation cavity", a reliable connection between the wheel box 21 and the supporting mechanism 1 is achieved, ensuring that there will be no relative displacement between the wheel box 21 and the supporting mechanism 1 during the forward movement of the mobile base. In addition, the above-mentioned connection method only performs horizontal constraints and does not perform vertical constraints, ensuring that the normal vertical force of the pressure detection mechanism 3 will not be affected.

[0058] The flange 214 serves as an extended load-bearing structure of the wheel box 21 and does not affect the arrangement of the accommodating cavity 213 (and the subsequent first shock-absorbing cavity 211 and the second shock-absorbing cavity 212 ) inside the wheel box 21 .

[0059] In practical applications, the thickness of the flange 214 may be increased to improve the strength of the flange.

[0060] Through the detachable connection between the flange 214 and the connecting plate 11, the wheel box 21 components can be quickly replaced, which significantly improves the maintainability of the equipment.

[0061] The fixing member 217 can be a bolt with a step. The step length of the bolt is greater than the sum of the thickness of the flange 214 of the wheel box 21, the thickness of the support mechanism 1 and the connecting plate 11, and the reserved gap. This ensures that when the bolt is tightened, the wheel box 21 is free 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.

[0062] According to one embodiment of the present application, Figure 3 As shown, along the traveling direction of the mobile platform, the wheel box 21 further includes a first shock-absorbing chamber 211 located in front of the accommodating chamber 213 and a second shock-absorbing chamber 212 located in the rear of the accommodating chamber 213 .

[0063] The wheel box 21 features a first shock-absorbing chamber 211 and a second shock-absorbing chamber 212 located in front and behind the accommodating chamber 213. This structural design, characterized by a "front and rear dual-buffer + central rigidity detection" layout, creates a composite system for graded impact energy absorption and stable load transfer. The front first shock-absorbing chamber 211 preferentially attenuates front-end impacts during the movement of the mobile pedestal (such as head-on collisions with the raised track 4), while the rear second shock-absorbing chamber 212 absorbs braking inertia or rear-end bump energy, creating a two-way dynamic buffer. This significantly reduces transient stress in the connection area of ​​the flange 214, preventing fatigue fracture at the edge of the wheel box 21 (i.e., the flange 214) caused by high-frequency impacts. The spatial separation of the first and second shock-absorbing chambers 211, 212, and the accommodating chamber 213 ensures that the vertical load transfer path of the pressure detection mechanism 3 is unaffected by the buffer structure.

[0064] 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 is dissipated laterally or vertically through the elastic elements in the damping cavity.

[0065] According to one embodiment of the present application, the mobile platform further includes a work position detection mechanism, which is disposed on the walking mechanism to obtain the position of the mobile platform.

[0066] The mobile platform provided in this application can also integrate a workstation detection mechanism to implement a workstation detection function: by monitoring the workstation (real-time position) where the mobile platform is located, combined with data collected by the pressure sensor, the pressure data is associated with the workstation. When abnormal pressure data occurs, the system provides feedback on the workstation where the abnormal data is located. After detecting the abnormal data, the system issues an alarm, indicating the workstation where the abnormal data originated. The mobile platform then re-passes the workstation, observing the real-time pressure data, and locating the exact location where the abnormal data originated, thereby detecting and locating the location of track 4 settlement and deformation.

[0067] After acquiring pressure data, the control system simultaneously combines it with workstation detection information and associates the pressure data with the corresponding workstation, creating a "pressure-workstation" mapping. The control system also displays the pressure data in real-time, using a graph or other form via the human-machine interface (HMI), allowing operators to monitor pressure changes during the platform's travel. The system pre-sets a pressure threshold (±10% of the normal range) to determine whether the pressure data is normal. When the measured pressure data exceeds the preset threshold, the system identifies it as abnormal, triggering an audible and visual alarm. The HMI clearly displays the corresponding workstation information, such as "Pressure Exceeded at Workstation 3," to alert the operator to the abnormality. If an abnormality is detected, the mobile platform can be re-routed through the abnormal workstation, continuously collecting pressure data during the second pass. By comparing the initial and second pass data and combining them with real-time monitoring results, the abnormality can be gradually narrowed down and ultimately pinpointed to its precise location, such as a track section where the pressure anomaly has settled or deformed. This enables detection and location of track settlement and deformation points.

[0068] The working detection mechanism can be a sensor (infrared ranging sensor) or a positioning device (RFID, encoder, GPS, etc.), such as: pre-embedded RFID tags (storing unique ID and coordinate information) every 1m on both sides of the track, and an RFID reader (reading distance 0.1~0.5m) installed on the wheel box 21, and the preset coordinates are queried by reading the tag ID to realize position detection.

[0069] According to one embodiment of the present application, Figure 1 and Figure 2As shown, a plurality of traveling mechanisms 2 are provided, and a pressure detection mechanism 3 is provided between at least one traveling mechanism 2 and the supporting mechanism 1 .

[0070] like Figure 1 and Figure 2 As shown, the running mechanisms 2 can be arranged into 5 groups in total, with 1 on each side, that is, 10 running mechanisms 2 in total. Figure 1 and Figure 2 As shown in FIG, a pressure detection mechanism 3 is provided between a traveling mechanism 2 and a supporting mechanism 1, that is, the number of the pressure detection mechanism 3 is one.

[0071] The multiple configurations of the running mechanisms 2 and the selective deployment of the pressure detection mechanisms 3 create an intelligent transportation system that combines distributed load-bearing and key-point monitoring. Multiple running mechanisms 2 evenly distribute the load, reducing the risk of single-wheel overload. The presence of at least one pressure detection mechanism 3 enables precise monitoring of the entire track 4 area, effectively controlling costs.

[0072] In practical applications, two groups of pressure detection mechanisms 3 may be provided, which not only takes cost issues into consideration but also avoids false detections caused by a single pressure detection mechanism 3 .

[0073] The mobile pedestal provided in the present application can monitor the overall straightness of the track 4 by monitoring the wheel pressure during the operation of the mobile pedestal by adding a pressure sensor to the walking mechanism 2, thereby realizing automatic detection of the straightness of the track 4. Each operation of the mobile pedestal will perform a detection on all positions along the entire length of the track 4, thereby realizing full-range detection of the track 4, with a high detection frequency and full coverage detection without missed detection. By presetting the pressure deviation value interval in the control system, an early warning can be issued for excessive deviation of the straightness of the track 4. The wheel box 21 is connected to the supporting mechanism 1 by a central shaft 12 and a stepped bolt. The pressure sensor is in the form of a pressure ring. While ensuring that the wheel box 21 and the supporting mechanism 1 are stably connected, the wheel box 21 is in a free state in the vertical direction, thereby accurately measuring the pressure on the wheel box 21.
