Description

Technical Field

[0001] This utility model relates to the field of engineering construction technology, and in particular to a tabletop rotating device and a track flatcar. Background Technology

[0002] The arch ribs of an arch bridge are assembled at a temporary assembly plant on the construction site. Individual members are then assembled into arch rib segments, which are then transported via a transport channel directly beneath the main cables carried by a cable crane. During hoisting, the arch rib segments must first be aligned longitudinally. However, the clear width of the transport channel in the transverse direction limits the length of the arch rib segments transported longitudinally. Currently, to avoid longitudinal alignment adjustments before hoisting and installation, the arch rib segments are typically fabricated to a length not exceeding the clear width of the channel. These segments are then directly loaded onto railcars in the temporary assembly plant for transport longitudinally. This construction method suffers from low construction efficiency. Utility Model Content

[0003] This utility model provides a platform rotating device and a track flatcar to solve the defects in the prior art where the length of the arch ribs needs to be restricted during the transportation of arch ribs of arch bridges, resulting in low construction efficiency. It realizes a platform rotating device that can change the placement direction of the arch ribs, so that the length of the arch ribs can be restricted to pass through the transportation channel set in the transverse direction of the bridge.

[0004] This utility model provides a tabletop rotation device including a rotation component, a support component, and a locking component. The rotation component includes a rotating shaft support and a turntable. The rotating shaft support is used to connect to a carrier, and the turntable is rotatably mounted on top of the rotating shaft support. The support component is located on the turntable and is used to support objects. The locking component is located on the support component and is used to switch between a locked state and an unlocked state. In the locked state, the support component is confined to the carrier. In the unlocked state, the confinement between the support component and the carrier is released.

[0005] According to the present invention, a tabletop rotating device is provided, wherein the rotating shaft support is provided with a turntable assembly groove, and the turntable is rotatably disposed in the turntable assembly groove.

[0006] According to the present invention, a tabletop rotating device is provided, wherein the side wall of the turntable assembly groove is provided with a rotating shaft assembly groove, the outer wall of the turntable is provided with a rotating shaft, and the rotating shaft is rotatably connected to the rotating shaft assembly groove.

[0007] According to the present invention, a tabletop rotating device is provided, wherein the support assembly includes a rotating support beam, the rotating support beam is detachably mounted on the turntable, and the rotating support beam has beam fixing ribs on both sides.

[0008] According to the present invention, a tabletop rotating device is provided, wherein the rotating support beam is provided with a limiting hole, and the locking member includes a rotating opening and closing pin, which is detachably provided in the limiting hole.

[0009] According to the present invention, a tabletop rotating device is provided, wherein the top of the support assembly is provided with a clamping component, which is used to limit the object.

[0010] This utility model also provides a rail flatcar, including a car body and a platform rotating device as described in any of the above embodiments, wherein a moving component is provided at the bottom of the car body; and the platform rotating device is provided at the top of the car body.

[0011] According to the present invention, a track flatcar includes at least two sets of drive wheel sets and at least two sets of driven wheel sets. The drive wheel sets are connected to a geared motor, which drives the drive wheel sets to rotate.

[0012] According to the present invention, a rail flatcar is provided, wherein the car body is equipped with an alarm light.

[0013] According to the present invention, a rail flatcar is provided, wherein the car body is further provided with a rail locker for locking with the rail.

[0014] The platform rotation device provided by this utility model allows construction teams to directly assemble long arch rib segments at a temporary assembly plant and transport them transversely on specially designed support components. Once these segments are transported to the construction site, the turntable can easily rotate around its central axis. Therefore, upon reaching the designated hoisting position, operators only need to unlock the locking mechanism between the support component and the carrier, and then rotate the turntable to quickly and smoothly adjust the entire support platform, along with the arch rib segments, from the initial transverse direction to the desired longitudinal direction. After the directional change is completed, the support component is relocked to ensure it remains stable, preparing for the next hoisting steps.

[0015] This invention not only greatly simplifies the transition from transportation to installation, avoiding complex on-site adjustments, but also significantly improves work efficiency. More importantly, it enables the use of longer, more complete arch rib segments for construction, even under transverse bridge transportation conditions with limited width, thereby optimizing the overall performance and aesthetics of the structure.

[0016] This utility model also provides a rail flatcar, which, since it includes a platform rotation device, also possesses the above-mentioned technical effects. Attached Figure Description

[0029] The following is combined Figures 1-5 This invention describes the tabletop rotation device provided by the present invention.

[0030] Figure 1 A front view of the track flatcar provided in an embodiment of the present invention is shown. Figure 2 An exploded view of the track flatcar provided in an embodiment of this utility model is shown. (Refer to...) Figure 1 and Figure 2 The present invention provides a tabletop rotation device comprising a rotation component 200, a support component 300, and a locking component 400. The rotation component 200 includes a pivot support 210 and a turntable 220. The pivot support 210 is used to connect to a carrier, and the turntable 220 is rotatably mounted on the top of the pivot support 210. The support component 300 is disposed on the turntable 220 and is used to support objects. The locking component 400 is disposed on the support component 300 and is used to switch between a locked state and an unlocked state. In the locked state, the support component 300 is limited to the carrier. In the unlocked state, the limitation between the support component 300 and the carrier is released.

[0031] In traditional construction, to ensure that arch rib segments can pass smoothly through the limited width of the transverse transport channel, the segments are often designed to be relatively short. This not only increases the workload of on-site splicing but also affects the overall construction efficiency. However, by using this invention, the construction team can directly assemble longer arch rib segments at a temporary assembly plant and place them transversely on a specially designed support assembly 300 for transport. Once these segments are transported to the construction site, because the turntable 220 can easily rotate around its central axis, upon reaching the designated hoisting position, the operator only needs to unlock the locking piece 400 between the support assembly 300 and the carrier, and then rotate the turntable 220 to quickly and smoothly adjust the entire support platform, along with the arch rib segments on it, from the initial transverse direction to the required longitudinal direction. After completing the directional change, the support assembly 300 is relocked to ensure it is stable and ready for the next hoisting steps.

[0032] This invention not only greatly simplifies the transition from transportation to installation, avoiding complex on-site adjustments, but also significantly improves work efficiency. More importantly, it enables the use of longer, more complete arch rib segments for construction, even under transverse bridge transportation conditions with limited width, thereby optimizing the overall performance and aesthetics of the structure.

[0033] Reference Figure 2 In some embodiments of this utility model, the rotating shaft support 210 is provided with a turntable assembly groove 212, and the turntable 220 is rotatably disposed in the turntable assembly groove 212.

[0034] The turntable mounting groove 212 provided on the rotating shaft support 210 mainly serves to provide a precise and stable installation position for the turntable 220 and ensure that the turntable 220 can rotate smoothly around the central axis. This design not only ensures that the turntable 220 can maintain stable rotation when bearing heavy objects, but also improves the safety and reliability of the entire device by limiting the lateral movement of the turntable 220.

[0035] In some possible embodiments, to further enhance the functionality of the turntable assembly slot 212, a lubrication system, such as an embedded oil groove or grease injection point, can be added inside the turntable assembly slot 212. This maintains low frictional resistance even after prolonged use, thereby extending the equipment's service life and reducing maintenance requirements. Furthermore, a sealing structure can be designed at the edge of the turntable assembly slot 212 to prevent the intrusion of external factors such as dust and moisture, protecting internal mechanical components from corrosion or wear. This helps maintain stable performance during long-term operation.

[0036] In other possible embodiments, an adjustable support mechanism can be provided at the bottom of the turntable assembly slot 212, allowing the support strength and distribution to be adjusted according to the specific load conditions, ensuring optimal support is provided whether under no-load or full-load conditions. This design not only enhances the device's adaptability to various working environments but also improves operational flexibility, enabling the platform rotation device to serve the special needs of bridge construction more efficiently and safely.

[0037] Figure 3 Example Figure 2 A magnified view of point A in the image. (Refer to...) Figure 2 and Figure 3 In some embodiments of this utility model, the side wall of the turntable assembly groove 212 is provided with a rotating shaft assembly groove 211, and the outer wall of the turntable 220 is provided with a rotating shaft 221, which is rotatably connected to the rotating shaft assembly groove 211.

[0038] In the above structure, the side wall of the turntable mounting groove 212 is provided with a shaft mounting groove 211, while the outer wall of the turntable 220 is equipped with a shaft 221. This arrangement allows the turntable 220 to rotate relative to the shaft 221 support through the rotatable connection between the shaft 221 and the shaft mounting groove 211. The shaft mounting groove 211 provides precise positioning and guidance for the shaft 221, ensuring that the turntable 220 can rotate smoothly around a fixed center point, which is crucial for maintaining the operational accuracy of the entire device. The shaft 221's function is not limited to providing rotation; it also supports the turntable 220 and the heavy load it bears. To ensure stability and safety during this process, the shaft 221 needs sufficient strength and rigidity to withstand the pressure from arch rib segments of varying weights. Simultaneously, good lubrication is key to maintaining efficient operation; therefore, dedicated lubrication channels can be provided on the surface of the shaft 221 or inside the shaft mounting groove 211 to reduce wear and extend service life.

[0039] In some possible embodiments, the shaft 221 can be manufactured using a self-lubricating material, thus maintaining a low coefficient of friction even in the absence of regular maintenance; alternatively, an intelligent monitoring system can be integrated into the shaft mounting slot 211 to monitor the operating status of the shaft 221 in real time, including parameters such as temperature and vibration, and provide timely warnings upon detecting abnormalities to prevent potential failures. Furthermore, a detachable shaft 221 design can be considered, facilitating quick replacement of damaged parts without affecting the overall structure, thereby improving maintenance efficiency.

[0040] Reference Figure 2 In some embodiments of this utility model, the support assembly 300 includes a rotating support beam 310, which is detachably mounted on the turntable 220 by bolts. The rotating support beam 310 has beam fixing ribs 320 on both sides, which can be specifically mounted on both sides of the rotating support beam 310 by bolts or welding.

[0041] In the above structure, the beam fixing ribs 320 provided on both sides of the rotating support beam 310 play a crucial role in structural reinforcement. The main function of the beam fixing ribs 320 is to increase the rigidity and stability of the rotating support beam 310, preventing bending or deformation under heavy loads. By evenly distributing the force throughout the structure, the beam fixing ribs 320 help ensure that the rotating support beam 310 can safely and reliably bear the arch rib segments and remain stable during rotation.

[0042] In some possible embodiments, to further enhance the effectiveness and adaptability of the crossbeam fixing rib 320, it can be manufactured using high-strength materials, such as high-toughness steel or composite materials. These materials not only provide higher strength and durability but also ensure sufficient load-bearing capacity while reducing weight. Furthermore, the cross-sectional shape of the crossbeam fixing rib 320 can be optimized according to actual needs, such as using T-shaped, L-shaped, or box-shaped sections to better resist forces from different directions, thereby improving the overall performance of the entire support system. In addition, to address potential wear issues after long-term use, a wear-resistant coating can be applied to the surface of the crossbeam fixing rib 320, or an easily replaceable protective layer can be designed for easy maintenance. This approach not only extends the service life of the crossbeam fixing rib 320 but also reduces downtime due to component failure, thereby improving work efficiency.

[0043] Reference Figure 2 In some embodiments of this utility model, the rotating support beam 310 is provided with a limiting hole 311, and the locking member 400 includes a rotating opening and closing pin, which is detachably disposed in the limiting hole 311. Correspondingly, the carrier of the rotating platform device is provided with a corresponding locking groove. When it is necessary to fix this utility model, that is, to prevent it from rotating, the rotating opening and closing pin can be passed through the limiting hole 311 and the locking groove. When it is necessary to remove the restriction, the rotating opening and closing pin can be pulled out.

[0044] In some embodiments of this utility model, the top of the support assembly 300 is provided with a clamping component (not shown in the figure), which is used to limit the object.

[0045] The clamping component located at the top of the support assembly 300 is a carefully designed device to ensure the stability of the arch rib segment or other heavy objects during transport and rotation. The core function of this component is to firmly clamp the object mechanically, preventing slippage or displacement during movement or orientation adjustments.

[0046] Specifically, the clamping component consists of two movable clamping arms that can converge towards the center or extend outward to accommodate objects of different sizes and shapes. The inner side of each clamping arm is lined with a high-friction material, such as a rubber pad, which not only increases the clamping force but also prevents damage to the object's surface. The movement of the clamping arms is controlled by a drive system, which can be a manually operated lever mechanism or an automated system driven by a hydraulic, pneumatic, or electric motor.

[0048] Reference Figure 1 , Figure 4 and Figure 5 This utility model also provides a rail flatcar including a car body 100 and a platform rotating device as described in any of the above embodiments. The car body 100 includes a frame 110, with a moving assembly disposed at the bottom of the frame 110; the platform rotating device is disposed at the top of the frame 110. The moving assembly includes at least two sets of drive wheel sets 140 and at least two sets of driven wheel sets 160. The drive wheel sets 140 are connected to a reduction motor 130, which drives the drive wheel sets 140 to rotate. Specifically, there are two sets of drive wheel sets 140 and two sets of driven wheel sets 160, and all four are respectively disposed at the four corners of the bottom of the frame 110, which makes the movement of the frame 110 more stable. In some other possible embodiments, when the locking member 400 is a pin-type structure, in order to cooperate with the limiting of the locking member 400, a limiting groove 112 can be provided on the frame 110, with the limiting groove 112 corresponding to the limiting hole 311. When it is necessary to allow the support assembly 300 to rotate, the locking member 400 can be inserted into the limiting hole 311 and the limiting groove 112. In some other possible embodiments, the top of the frame 110 is also provided with an auxiliary support wheel 150, which rolls in contact with the bottom of the rotating support beam 310, thereby assisting the rotation of the rotating support beam 310.

Furthermore, the support assembly 300 is equipped with a displacement sensor, which is signal-connected to the alarm light 120. When the support assembly 300 is about to be touched during rotation, the alarm light 120 will sound an alarm.
