Description

Technical Field

[0001] This invention relates to the field of corrugated steel web plate installation technology, specifically a bidirectional adjustment and positioning device for corrugated steel web plate installation. Background Technology

[0002] Corrugated steel web prestressed concrete box girder bridges, also known as corrugated steel web PC bridges, refer to box girders in which corrugated steel plates replace the concrete webs of prestressed concrete box girders. Their significant feature is that 10-20mm thick steel plates replace 30-80cm thick concrete webs.

[0003] In existing bridge installations, the installation and transportation of corrugated steel web plates are generally carried out using a crane. During the installation process, the corrugated steel web plates are manually adjusted by pulling on the traction ropes fixed to them to ensure that they are stably embedded in the bridge installation position. However, the manual adjustment force is uncontrollable, highly variable, and cannot accurately adjust the position of the corrugated steel web plates. Furthermore, it is impossible to ensure that the corrugated steel web plates remain level during the adjustment process. Summary of the Invention

An installation chamber is provided in the lower movable frame, and both ends of the bidirectional threaded rod extend into the installation chamber. A drive gear is rotatably installed in the upper installation chamber, and a driven gear is fixedly installed on the upper end of the upper bidirectional threaded rod, and the driven gear meshes with the drive gear.

[0010] As a further embodiment of the present invention, the lifting assembly includes an upper threaded component, and multiple sets of the upper threaded components are provided and rotatably installed at both ends of the upper support frame. The upper threaded component is internally threaded with an upper threaded rod, and the lower end of the upper threaded rod is fixedly connected to the upper mounting frame.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figures 1-8This invention provides a technical solution: a bidirectional adjustment and positioning device for installing corrugated steel web plates, comprising an upper support frame 1, upper mounting frames 5 mounted on both ends of the upper support frame 1 via lifting components, an upper movable frame 3 slidably connected to the lower end of the upper mounting frame 5, an upper level 2 disposed between the upper mounting frames 5, upper telescopic rods 4 fixedly mounted on both ends of the lower surface of the upper movable frame 3, a lower support frame 15 fixedly mounted on the lower end of the upper telescopic rods 4, a lower level 33 fixedly mounted on one side of the lower support frame 15, side mounting frames 7 fixedly mounted on both ends of the lower surface of the lower support frame 15, a plurality of mounting threaded rods 10 rotatably mounted on the side mounting frames 7, a lower movable frame 14 fixedly mounted on the end of the threaded rods 10 away from the side mounting frames 7, a clamping frame 8 fixedly mounted between the lower movable frames 14, a clamping component disposed on the clamping frame 8, and a transmission component disposed on the lower support frame 15, the transmission component being capable of driving the threaded rods 10 at both ends of the lower support frame 15 to rotate simultaneously.

[0029] During operation, the boom of the transfer device in this invention is fixedly connected to the upper support frame 1, and the upper movable frame 3 slides under the upper mounting frame 5, so that the upper movable frame 3 is at both ends of the corrugated plate 9. Then, the lower threaded rod 10 is driven to rotate, so that the clamping frame 8 is close to both sides of the corrugated plate 9, so that the clamping components on the clamping frame 8 can be respectively positioned on the upper and lower sides of the corrugated plate 9. The clamping components approach each other to clamp the corrugated plate 9 on the clamping frame 8. Then, the boom drives the corrugated plate 9 to move in the direction of bridge installation. During the movement, the upper level 2 and the lower level 33 monitor the horizontal state of the upper mounting frame 5 and the lower support frame 15, respectively. The lifting component and the upper telescopic rod 4 can adjust the distance between the two ends of the upper mounting frame 5 and the upper support frame 1 and the distance between the lower support frame 15 and the two ends of the upper movable frame 3 according to the monitoring results of the upper level 2 and the lower level 33, so as to ensure that the corrugated plate 9 clamped on the clamping frame 8 is always in a horizontal state, ensuring that the corrugated plate 9 can be accurately embedded into the bridge installation position, reducing the collision of the corrugated plate 9 during the transfer process, and ensuring the stability of the corrugated plate 9 during the transfer process. Furthermore, the transmission assembly (the rotating motor drives the transmission rod 32 to rotate, and the two ends of the rotating transmission rod 32 drive the transmission gear 11 on one side to rotate through the upper transmission member 13. Adjacent transmission gears 11 mesh with each other and, under the action of the lower transmission member 12, drive multiple sets of upper and lower transmission gears 11 to rotate simultaneously. The rotation of the transmission gears 11 interacts with the lower threaded rod 10, thereby driving the lower threaded rod 10 to move relative to each other. The relative movement of the lower threaded rod 10 drives the lower movable frame 14 to move relative to each other. The movement of the lower movable frame 14 drives the clamping frame 8 to move relative to each other to clamp the wave plate 9. The rotating motor drives the transmission rod 32 to rotate in the opposite direction, thereby driving the clamping frame 8 to move rapidly in opposite directions. The detachment of the corrugated plate 9 ensures that the moving distance of the clamping frames 8 on both sides is consistent, and that the clamping positions of the clamping frames 8 on both sides of the corrugated plate 9 remain symmetrical. This ensures that the corrugated plate 9 is always in the middle position of the device, ensuring that the force on the corrugated plate 9 is uniform during the transfer process, reducing the tearing that the clamping components themselves may cause to the corrugated plate 9, and facilitating the positioning of the corrugated plate 9 by passing through the side mounting frame 7 horizontally and vertically during the installation process, so as to quickly find the installation position of the corrugated plate 9. At the same time, the clamping frames 8 move in opposite directions to facilitate the quick detachment of the corrugated plate 9 from the device, avoiding the trouble of disassembling the traction rope in the past, and improving the installation efficiency of the corrugated plate 9.

[0030] In this invention, the corrugated plate 9 is fixed below the device by the clamping frame 8. The corrugated plate 9 is moved to the designated installation position by moving the upper support frame 1. During the movement, the lifting component and the upper telescopic rod 4 can adjust the distance between the two ends of the upper mounting frame 5 and the upper support frame 1 and the distance between the lower support frame 15 and the two ends of the upper movable frame 3 according to the monitoring results of the upper level 2 and the lower level 33. This ensures that the corrugated plate 9 clamped on the clamping frame 8 is always in a horizontal state, ensuring that the corrugated plate 9 can be accurately embedded into the bridge installation position, reducing the collision of the corrugated plate 9 during the transportation process, and ensuring the stability of the corrugated plate 9 during the transportation process.

[0031] In this invention, the clamping positions of the two clamping frames 8 on both sides of the corrugated plate 9 are kept symmetrical, thereby ensuring that the corrugated plate 9 is always in the middle position of the device, ensuring that the force on the corrugated plate 9 is uniform during the transfer process, reducing the tearing that the clamping components themselves may cause to the corrugated plate 9, and facilitating the positioning of the corrugated plate 9 by passing through the side mounting frame 7 horizontally and vertically during the installation process, so as to quickly find the installation position of the corrugated plate 9. At the same time, the clamping frames 8 move backward to facilitate the quick detachment of the corrugated plate 9 from the device, avoiding the trouble of disassembling the traction rope in the past, and improving the installation efficiency of the corrugated plate 9.

[0032] As a further embodiment of the present invention, the transmission assembly includes a transmission rod 32, which is rotatably mounted above the lower support frame 15. A transmission gear 11 is rotatably mounted on the side mounting frame 7 at a position corresponding to the lower threaded rod 10. The transmission gear 11 is threadedly connected to the lower threaded rod 10. A lower transmission member 12 is provided between the transmission gears 11 on the same side, and an upper transmission member 13 is provided between the upper transmission gear 11 and the transmission rod 32.

[0033] During operation, the rotating motor drives the transmission rod 32 to rotate. The two ends of the rotating transmission rod 32 drive the transmission gear 11 on one side to rotate through the upper transmission component 13. Adjacent transmission gears 11 mesh with each other and drive multiple sets of transmission gears 11 to rotate simultaneously under the action of the lower transmission component 12. The rotation of the transmission gears 11 interacts with the lower threaded rod 10, thereby driving the lower threaded rod 10 to move relative to each other. The relative movement of the lower threaded rod 10 drives the lower movable frame 14 to move relative to each other. The movement of the lower movable frame 14 drives the clamping frame 8 to move relative to each other to clamp the wave plate 9. The rotating motor drives the transmission rod 32 to rotate in the opposite direction, thereby driving the clamping frame 8 to move in opposite directions to quickly disengage from the wave plate 9.

[0034] As a further embodiment of the present invention, the clamping assembly includes a bidirectional threaded rod 24, which is rotatably mounted between the lower movable frames 14. Threaded sleeves 25 are symmetrically mounted on the upper and lower sides of the bidirectional threaded rod 24 and are threadedly connected to the bidirectional threaded rod 24. A fixing rod 29 is fixedly mounted on one side of the lower movable frames 14 corresponding to the bidirectional threaded rod 24, and the fixing rod 29 is slidably connected to the threaded sleeve 25.

[0035] During operation, the clamping motor drives the drive gear 34 to rotate, which in turn drives the driven gear 19 to rotate. The driven gear 19 then drives the bidirectional threaded rod 24 to rotate, which in turn drives the threaded sleeve 25 on it to move relative to each other. The movement of the threaded sleeve 25 causes the extension plates 20 to move closer to each other, bringing the extension plates 20 closer to the surface of the corrugated plate 9. Then, the extension plates 20 extend by the upper and lower telescopic rods 21, which then press the clamping plate 22 against the surface of the corrugated plate 9, thus fixing and clamping the corrugated plate 9. The extension plates 20 can also rotate around the threaded sleeve 25 (the micro motor 28 drives the gear 27 to rotate, which in turn drives the gear ring 26 to rotate, which in turn drives the connecting ring 23 to rotate, which in turn drives the upper and lower connecting rings 23 to rotate simultaneously via the rotating rod 30, which in turn drives the extension plates 20 to rotate, thereby adjusting the position of the extension plates 20). This allows the extension plates 20 to rotate, adjusting their angular relationship with the clamping frame 8 to accommodate more types of corrugated plates 9 and increasing the adaptability of the clamping equipment.

[0036] As a further embodiment of the present invention, a connecting ring 23 is rotatably mounted on each threaded sleeve 25. An extension plate 20 is fixedly mounted on one side of the connecting ring 23. A lower telescopic rod 21 is fixedly mounted on the side of the extension plate 20 away from the lower movable frame 14. A clamping plate 22 is fixedly mounted on the end of the lower telescopic rod 21 away from the extension plate 20. A connecting plate 31 is rotatably mounted on the side of the lower movable frame 14 near the threaded sleeve 25. A rotating rod 30 is fixedly mounted between the connecting plates 31. The rotating rod 30 is slidably connected to the connecting ring 23. A corrugated plate 9 is provided between the clamping plates 22.

[0037] As a further embodiment of the present invention, a micro motor 28 is fixedly installed on the upper threaded sleeve 25, and a drive gear 27 is fixedly installed on the output end of the micro motor 28. A gear ring 26 is fixedly installed on the upper surface of the upper connecting ring 23, and the gear ring 26 meshes with the drive gear 27. An installation chamber 18 is provided in the lower movable frame 14, and both ends of the bidirectional threaded rod 24 extend into the installation chamber 18. A drive gear 34 is rotatably installed in the upper installation chamber 18, and a driven gear 19 is fixedly installed on the upper end of the upper bidirectional threaded rod 24, and the driven gear 19 meshes with the drive gear 34.

[0038] As a further embodiment of the present invention, the lifting assembly includes an upper threaded component 16, which is provided in multiple sets and rotatably mounted at both ends of the upper support frame 1. The upper threaded component 16 is internally threaded with an upper threaded rod 6, the lower end of the upper threaded rod 6 is fixedly connected to the upper mounting frame 5, and a limiter 17 is provided between adjacent upper threaded components 16.

[0039] As a further embodiment of the present invention, a rotating motor is fixedly installed on the lower support frame 15, and the output end of the rotating motor is fixedly connected to the transmission rod 32. A clamping motor is fixedly installed inside the upper lower movable frame 14, and the output end of the clamping motor is fixedly connected to the drive gear 34.

[0040] As a further embodiment of the present invention, a driving device is provided on one side of the upper support frame 1 corresponding to the limiting member 17. The driving device includes a positioning gear and a limiting gear. The positioning gear is fixedly connected to the upper threaded member 16 on one side of the limiting member 17. The limiting gear is rotatably mounted on the upper support frame 1 and meshes with the positioning gear. An information processing module and a control module are provided on the upper support frame 1. The information processing module is electrically connected to both the upper level 2 and the lower level 33. The control module is Bluetooth connected to the driving device and the upper telescopic rod 4.
