Description

Technical Field

[0001] The present invention belongs to the technical field of conveying devices, and specifically relates to a suspension conveying device for precast box girders. Background Technique

[0002] In large-scale construction projects, as a key load-bearing structure, the efficient and safe transportation and installation of precast box girders have an important impact on the project progress and quality. At present, the transportation of precast box girders mainly relies on a series of complex mechanical devices and operation processes, which are often cumbersome and inefficient, becoming a factor restricting the project speed and cost.

[0003] For the movement and transportation of precast box girders, the industry mainly relies on a series of complex fixed and lifting equipment. Specifically, before moving the box girder, the staff needs to use special fixing structures or fixtures to firmly lock the box girder. Subsequently, a crane or other lifting equipment is required to slowly lift the fixed box girder and accurately move it above the transport vehicle or mobile equipment. After that, the box girder needs to be carefully placed on the mobile equipment and fixed again to ensure stability during transportation. Finally, the mobile equipment carries the box girder to the designated position to complete the transportation task. However, the above transportation method has obvious deficiencies and limitations. The entire process involves multiple fixings, liftings, movements, and re-fixings, which are cumbersome and inefficient, and it is difficult to meet the requirements of modern projects for rapid construction.

[0004] Therefore, the present invention provides a suspension conveying device for precast box girders. Summary of the Invention

[0005] In order to make up for the deficiencies of the prior art and solve at least one technical problem proposed in the background technique.

[0006] The technical solution adopted by the present invention to solve its technical problems is as follows: A suspension conveying device for precast box girders according to the present invention includes a base. A plurality of cushion blocks are arranged inside the base. A box girder body is lapped between the tops of the plurality of cushion blocks. The base is in a "C" shape. Translation shafts are symmetrically arranged on the top of the base. A translation component is arranged between the translation shafts and the base. A plurality of bottom connectors are rotatably installed on the outer walls of the translation shafts. Inclined plates are fixedly installed on the outer walls of the bottom connectors. Top connectors are fixedly installed at the ends of the inclined plates away from the bottom connectors. Connecting columns are installed between the top connectors on the same side. Support shafts are fixedly installed on the outer walls of the connecting columns. The outer walls of the support shafts are in contact with the outer walls of the box girder body. Anti-slip patterns are provided on the outer walls of the support shafts.

[0007] Preferably, the translation component includes translation blocks, and the top of the base is symmetrically provided with a plurality of grooves. The translation blocks are slidably installed on the inner wall of the grooves respectively. A cylinder is fixedly installed on the inner wall of each groove. The output shaft of the cylinder is fixedly connected to the outer wall of the translation block respectively. The translation blocks are divided into two groups, and two translation shafts are respectively installed between the two groups of translation blocks.

[0008] Preferably, each of the translation blocks has a mounting base fixedly installed on its top, and mounting columns are fixedly installed between the mounting bases on the same side. Each mounting column has an upper abutment column fixedly installed on its outer wall, and two upper abutment columns are symmetrically arranged above the inclined surfaces of two of the inclined plates.

[0009] Preferably, the top of the base is symmetrically fixedly equipped with a bracket, and the horizontal section of the bracket is fixedly equipped with a lower abutment column. The two lower abutment columns are symmetrically arranged below the inclined surfaces of two of the inclined plates.

[0010] Preferably, a top limiting plate is provided above the base, and a support component is provided between the top limiting plate and the base. The top limiting plate is located above the box girder body and is used to increase the stability of the box girder body during hoisting.

[0011] Preferably, the support assembly includes a gantry frame, which is fixedly installed on the outer wall of the base. The top limiting plate is located below the horizontal section of the gantry frame, and a hinge is fixedly installed at the bottom of the horizontal section of the gantry frame. The bottom of the hinge is fixedly connected to the top of the top limiting plate.

[0012] Preferably, a positioning seat is symmetrically fixedly installed on the top of the gantry frame, and a pressure sensor is fixedly installed on the inner wall of each positioning seat. An arc-shaped elastic element is symmetrically fixedly installed on the top of the top limiting plate. The two arc-shaped elastic elements are located on both sides of the hinge. The end of the arc-shaped elastic element away from the top limiting plate passes through the gantry frame and is fixedly connected to the pressure sensor. An alarm is fixedly installed on the top of the gantry frame.

[0013] Preferably, a number of sets of movable wheels are symmetrically fixedly installed on the bottom of the base, and a central component is provided on the top of the base.

[0014] Preferably, the centering component includes vertical plates, and several vertical plates are provided and fixedly installed on one side of the mounting base. Each vertical plate has a rotating shaft rotatably installed on its inner wall, and rotating plates are symmetrically installed on the outer wall of each rotating shaft. A positioning plate is fixedly installed between each pair of corresponding rotating plates, and a positioning rod is fixedly installed on the inner wall of each vertical plate.

[0015] Preferably, a support frame is fixedly installed on the top of the base, a handrail is fixedly installed on the inner wall of the support frame, and a traction device is fixedly installed on the outer wall of the base.

[0016] The beneficial effects of this invention are as follows:

[0017] 1. Traditional transportation devices often require multiple fixing, hoisting, moving, and re-fixing processes, which are cumbersome and time-consuming. However, this invention only requires moving the base to the outside of the box girder, positioning the box girder at the central notch, and activating the translation component to achieve automatic lifting and transportation of the box girder. Once it reaches the designated position, the translation component can be reversed to easily unload the material. This integrated operation method greatly simplifies the process, reduces operational difficulty and manpower requirements, and can significantly shorten the construction cycle and accelerate project progress in large-scale box girder production and transportation scenarios.

[0018] 2. The combination of pressure sensor and arc-shaped elastic element constitutes a sensitive monitoring system. When the box girder tilts, the top limiting plate tilts accordingly, causing the amount of expansion and contraction of the arc-shaped elastic elements on both sides to change. This allows the pressure sensor to detect the abnormal pressure difference on both sides. This design can accurately sense the slight tilt changes of the box girder, providing a reliable basis for timely adjustment.

[0019] 3. This invention achieves automatic centering adjustment of the device through the cooperation of the flip plate, positioning plate and moving wheels. The positioning plate contacts the box girder before the support shaft. The weight of the box girder causes the device to move adaptively through the moving wheels until both positioning plates are in contact with the box girder. This ensures that the box girder can be accurately located in the center of the base. This precise automatic centering function effectively avoids the lifting and tilting problem caused by the position deviation of the box girder, and provides a guarantee for subsequent safe and stable transportation.

[0030] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0031] like Figures 1 to 5As shown in the figure, a suspension conveying device for precast box girders according to an embodiment of the present invention includes a base 1. A plurality of cushion blocks 2 are provided inside the base 1. A box girder body 3 is lapped between the tops of the plurality of cushion blocks 2. The base 1 is in a "C" shape. Translation shafts 4 are symmetrically arranged on the top of the base 1. A translation component is provided between the translation shafts 4 and the base 1. A plurality of bottom connectors 5 are rotatably installed on the outer walls of the translation shafts 4. Inclined plates 6 are fixedly installed on the outer walls of the bottom connectors 5. Top connectors 7 are fixedly installed at the ends of the inclined plates 6 away from the bottom connectors 5. Connecting columns 8 are installed between the top connectors 7 on the same side. Support shafts 9 are fixedly installed on the outer walls of the connecting columns 8. The outer walls of the support shafts 9 are in contact with the outer walls of the box girder body 3. Anti-slip patterns are provided on the outer walls of the support shafts 9. When conveying the box girder body 3, first move the device to the outside of the box girder body 3 so that the box girder body 3 is located at the central notch of the base 1. At this time, the support shafts 9 are distributed on both sides of the box girder body 3. Start the translation component. The translation component will drive the two translation shafts 4 on both sides to move synchronously towards the box girder body 3. When the translation shafts 4 move, they will drive the inclined plates 6 through the bottom connectors 5. When the inclined plates 6 move, they will drive the connecting columns 8 through the top connectors 7. When the connecting columns 8 move, they will drive the support shafts 9 to move. When the two support shafts 9 contact the box girder body 3, the bottom connectors 5 will rotate relative to the translation shafts 4. The support shafts 9 will slide along the inclined surface of the box girder body 3 and abut against the two side corners. Then, as the two translation shafts 4 continue to approach, the support shafts 9 will lift the box girder body 3 from both sides, separating it from the cushion blocks 2. After that, the box girder body 3 can be transported by moving the device. When reaching the designated position, the two translation shafts 4 are synchronously moved away through the translation component to achieve unloading. Traditional conveying devices often require multiple fixings, hoistings, movements, and re-fixings, with a cumbersome and time-consuming process. However, in the present invention, only the base 1 needs to be moved to the outside of the box girder, making the box girder located at the central notch, and starting the translation component to achieve automatic lifting and transportation of the box girder. After reaching the designated position, reversing the operation of the translation component can easily unload the material. This integrated operation method greatly simplifies the process, reduces the operation difficulty and manpower requirements, and can significantly shorten the construction period and speed up the project progress in large-scale box girder production and transportation scenarios.

[0032] As Figures 4 to 5As shown, the translation assembly includes translation blocks 10. Several grooves are symmetrically opened on the top of the base 1. The translation blocks 10 are slidably installed on the inner wall of the grooves. Cylinders 11 are fixedly installed on the inner wall of each groove. The output shafts of the cylinders 11 are fixedly connected to the outer wall of the translation blocks 10. The translation blocks 10 are divided into two groups, and two translation shafts 4 are installed between the two groups of translation blocks 10. After the translation assembly is started, the cylinders 11 will extend and retract synchronously. When the cylinders 11 retract, the two groups of translation blocks 10 will move closer to each other synchronously, thereby driving the two translation shafts 4 to move closer to each other, realizing the lifting of the box girder body 3. When the cylinders 11 extend, the two groups of translation blocks 10 will move away from each other synchronously, thereby driving the two translation shafts 4 to move away from each other, realizing the unloading of the box girder body 3.

[0033] like Figures 3 to 6 As shown, each translation block 10 has a mounting base 12 fixedly installed on its top. Mounting columns 13 are fixedly installed between the mounting bases 12 on the same side. Upper abutment columns 14 are fixedly installed on the outer walls of each mounting column 13. Two upper abutment columns 14 are symmetrically positioned above the inclined surfaces of two inclined plates 6. The mounting bases 12 and mounting columns 13 position the upper abutment columns 14, ensuring that each upper abutment column 14 is located above the inclined surface of one of the inclined plates 6 on each side. This limits the movement of the inclined plates 6 on both sides, preventing them from excessively rotating outwards. On one hand, this prevents the inclined plates 6 from rotating to the outside before lifting, avoiding device malfunctions and operational delays caused by improper positioning of the inclined plates 6, thus improving the reliability and efficiency of the device. On the other hand, it prevents the box girder body 3 from falling during transportation due to the inclined plates 6 rotating to the outside, ensuring the safe transport of the box girder. This allows the device to operate stably under various road conditions and transportation environments, reducing the risk of safety accidents and equipment damage caused by the box girder falling, and ensuring the continuity and safety of construction.

[0034] like Figures 3 to 4 As shown, a bracket 15 is symmetrically fixedly installed on the top of the base 1. A lower abutment column 16 is fixedly installed on the horizontal section of the bracket 15. The two lower abutment columns 16 are symmetrically arranged below the inclined surfaces of the two inclined plates 6. The bracket 15 positions the lower abutment columns 16 so that the two lower abutment columns 16 are located below the inclined surfaces of one of the inclined plates 6 on each side, thereby limiting the inclined plates 6 on both sides. This ensures that the inclined plates 6 remain inclined downward in their natural state, thus ensuring that the box girder body 3 can be effectively lifted during the lifting operation, preventing jamming, and improving the smoothness and reliability of the device's operation.

[0035] like Figure 3 and Figure 7As shown, a top limiting plate 17 is provided above the base 1, and a support assembly is provided between the top limiting plate 17 and the base 1. The top limiting plate 17 is located above the box girder body 3 and is used to increase the stability of the box girder body 3 during hoisting. The top limiting plate 17 is set above the box girder body 3 through the support assembly. When the box girder body 3 is lifted, the top of the box girder body 3 will fit against the bottom of the top limiting plate 17. The top limiting plate 17 limits the box girder body 3 from the top, forming an all-round constraint system with the support shaft 9. This multi-directional limiting method can effectively prevent the box girder from tilting, shaking or even falling during transportation, greatly improving the stability of box girder transportation, ensuring that the box girder can safely and smoothly reach the designated position, and reducing the risk of damage to the box girder due to unstable transportation.

[0036] like Figure 3 and Figure 7 As shown, the support assembly includes a gantry frame 18, which is fixedly installed on the outer wall of the base 1. The top limiting plate 17 is located below the horizontal section of the gantry frame 18. A hinge 19 is fixedly installed at the bottom of the horizontal section of the gantry frame 18, and the bottom of the hinge 19 is fixedly connected to the top of the top limiting plate 17. The top limiting plate 17 is installed through the gantry frame 18 and the hinge 19, so that the top limiting plate 17 is installed above the box girder body 3. The hinge 19 allows the top limiting plate 17 to rotate, thereby automatically adapting to fit the top of the box girder body 3.

[0037] like Figure 7As shown, positioning seats 20 are symmetrically fixedly installed on the top of the gantry 18. Pressure sensors 21 are fixedly installed on the inner walls of the positioning seats 20. Arc-shaped elastic elements 22 are symmetrically fixedly installed on the top of the top limiting plate 17. The two arc-shaped elastic elements 22 are located on both sides of the hinge 19. The end of the arc-shaped elastic element 22 away from the top limiting plate 17 passes through the gantry 18 and is fixedly connected to the pressure sensor 21. An alarm 23 is fixedly installed on the top of the gantry 18. During the conveying operation, when the conveyed box girder tilts, the top limiting plate 17 will tilt accordingly. At this time, the two arc-shaped elastic elements 22 located above the top limiting plate 17 will expand and contract accordingly due to the tilt. The pressure sensor 21 will detect the abnormal pressure difference on both sides, and thus trigger an alarm through the alarm 23, allowing the staff to make timely adjustments. In summary, the combination of pressure sensor 21 and arc-shaped elastic element 22 constitutes a sensitive monitoring system. When the box girder tilts, the top limiting plate 17 tilts accordingly, causing a change in the expansion and contraction of the arc-shaped elastic elements 22 on both sides. This, in turn, allows pressure sensor 21 to detect abnormal pressure differences on both sides. This design can accurately sense minute tilt changes in the box girder, providing a reliable basis for timely adjustments. Once pressure sensor 21 detects an abnormal pressure difference, alarm 23 will immediately sound an alarm. This real-time early warning mechanism enables staff to detect box girder tilting problems at the first moment and take corresponding adjustment measures, effectively avoiding accidents caused by excessive tilting of the box girder. This greatly improves the safety of the transportation process, reduces human error in observation and judgment, improves the accuracy and reliability of monitoring, and makes the device more intelligent.

[0038] like Figures 2 to 3 As shown, several sets of moving wheels 24 are symmetrically fixedly installed on the bottom of the base 1, and a centering component is set on the top of the base 1. Before the device is moved to the outside of the box girder body 3 for conveying, the centering component can center and position the device. During the positioning process, the device will move through the moving wheels 24, so that the box girder body 3 is located in the center of the base 1, realizing automatic centering. The precise positioning ensures that the box girder is subjected to uniform force during the lifting process, effectively preventing the box girder from tilting, and laying the foundation for subsequent safe transportation.

[0039] like Figure 6 and Figure 8As shown, the centering component includes vertical plates 25, of which several are fixedly installed on one side of the mounting base 12. A flipping shaft 26 is rotatably mounted on the inner wall of each vertical plate 25, and flipping plates 27 are symmetrically mounted on the outer wall of each flipping shaft 26. A positioning plate 28 is fixedly installed between each corresponding pair of flipping plates 27. A positioning rod 29 is fixedly installed on the inner wall of each vertical plate 25. Before moving the device to the outside of the box girder body 3 for conveying operations, the flipping plates 27 are first flipped using the flipping shafts 26. Near the side of the box girder body 3, the flipping plate 27 will be horizontally positioned above the positioning rod 29. At this time, the cylinder 11 retracts, and the translation block 10 will move the vertical plate 25 towards the box girder body 3 via the mounting base 12. This will cause the flipping plate 27 to move the positioning plate 28 towards the box girder body 3. The positioning plate 28 will contact the box girder body 3 before the support shaft 9. Due to the heavy weight of the box girder body 3, after the positioning plate 28 contacts the box girder body 3, the device will adaptively adjust its position via the moving wheels 24. The device automatically centers itself until both positioning plates 28 are in contact with the box girder body 3, thus achieving automatic centering adjustment. After centering is completed, the flip plate 27 is rotated again to the side away from the box girder body 3, and the lifting operation can then begin. In summary, this invention achieves automatic centering adjustment of the device through the cooperation of the flip plate 27, positioning plate 28, and moving wheel 24. The positioning plate 28 contacts the box girder before the support shaft 9, and the weight of the box girder causes the device to move adaptively via the moving wheel 24 until both positioning plates 28 are in contact with the box girder, ensuring that the box girder is accurately positioned in the center of the base 1. This precise automatic centering function effectively avoids the lifting tilting problem caused by the box girder's position deviation, providing a guarantee for subsequent safe and stable transportation. The operator only needs to simply flip the flip plate 27 and activate the cylinder 11 to retract, which will achieve automatic centering adjustment. After centering is completed, the entire process is simple to operate, requiring no complex manual measurement and adjustment, greatly improving work efficiency and reducing operation time and labor costs.

[0040] like Figures 1 to 3 As shown, a support frame 30 is fixedly installed on the top of the base 1, a handrail 31 is fixedly installed on the inner wall of the support frame 30, and a traction device 32 is fixedly installed on the outer wall of the base 1. The handrail 31 is connected to the base 1 through the support frame 30, and the device can be moved by pushing the handrail 31. By connecting the traction device 32 to the tractor, the device can be moved by the tractor to realize the transportation of the box girder.
