Description

Technical Field

[0001] This utility model relates to the field of prestressed construction technology, specifically a mobile prestressed tensioning platform device. Background Technology

[0002] In certain special structures where there are specific requirements for structural deflection and strength, prestressing is used to pre-stress the reinforced concrete members to prevent premature cracking or excessive bending deflection that could affect their performance. Prestressing is a method of applying stress to concrete members during the prefabrication process to improve their performance. This method involves tensioning the reinforcing bars before pouring concrete and temporarily anchoring the tensioned prestressing tendons to a platform or steel mold. Then, the concrete is poured, and once the concrete strength reaches a certain level, the prestressing tendons are released. The prestress is then applied to the concrete using the bond between the prestressing tendons and the concrete.

[0003] Currently, the tensioning platform structure used in the pre-tensioning method is relatively complex. It requires the installation of pile foundations at the bottom of the tensioning platform to fix it. This has significant limitations in use, as it cannot be moved, which is very inconvenient. At the same time, it is not easy to adjust the tensioning height.

[0004] Therefore, those skilled in the art have provided a movable prestressed tensioning platform device to solve the problems mentioned in the background art. Utility Model Content

[0020] Please see Figures 1-4 In this embodiment of the utility model, a movable prestressed tensioning platform device includes a support base 1, a base 2 and a protective cover 6 connected to the upper end of the support base 1, a platform 4 rotatably connected to the base 2, the platform 4 can rotate based on the base 2, and an anchor 5 is fixedly connected to one end of the platform 4.

[0021] A support rod 13 is fixedly connected inside the support base 1. A toothed plate 14 is slidably connected to the support rod 13. A first connecting frame 15 is fixedly connected to the toothed plate 14. A support column 16 is fixedly connected to the lower end of the first connecting frame 15. The support column 16 can penetrate to the outside of the support base 1 and support the entire device. A second connecting frame 17 is fixedly connected to the support rod 13. A pulley 18 is provided at the lower end of the second connecting frame 17. The pulley 18 penetrates to the outside of the support base 1, and the entire device can be easily moved by the pulley 18.

[0022] The protective cover 6 is equipped with a bidirectional motor 7. A first connecting wheel 8 is fixedly connected to the output shaft of the bidirectional motor 7. A second connecting wheel 10 is rotatably connected inside the support base 1. The first connecting wheel 8 and the second connecting wheel 10 are connected by a belt 9. When the bidirectional motor 7 drives the first connecting wheel 8 to work, the second connecting wheel 10 can be driven to rotate synchronously through the belt 9. A rotating column 11 is also rotatably connected inside the support base 1. A gear 12 is fixedly connected to one end of the rotating column 11. The gear 12 meshes with the toothed plate 14. When the gear 12 rotates, it will drive the toothed plate 14 to move, thereby moving the support column 16.

[0023] A connecting rod 19 is embedded in the support base 1. A first limiting block 20 and a second limiting block 21 are fixedly connected to the connecting rod 19. The second connecting wheel 10 and the rotating column 11 are respectively provided with limiting grooves that are adapted to the first limiting block 20 and the second limiting block 21. The second limiting block 21 is always located inside the rotating column 11, which can limit the rotation of the rotating column 11. A pull ring 22 is fixedly connected to one end of the connecting rod 19 located outside the support base 1. The connecting rod 19 can be moved through the pull ring 22, which drives the first limiting block 20 to be inserted into the second connecting wheel 10. When the second connecting wheel 10 rotates, it will drive the rotating column 11 to rotate. A limiting strip 23 is fixedly connected to the connecting rod 19. The support base 1 is provided with a groove that is adapted to the limiting strip 23. When the limiting strip 23 is in the groove, the connecting rod 19 can be fixed based on the support base 1.

[0024] A rotating rod 24 is rotatably connected to the base 2. The rotating rod 24 passes through the interior of the protective cover 6 and is connected to the output shaft of the bidirectional motor 7. When the bidirectional motor 7 is working, it will drive the rotating rod 24 to rotate. A moving block 25 is sleeved on the rotating rod 24. A slider is set inside the moving block 25. A spiral groove adapted to the slider is opened on the rotating rod 24. When the rotating rod 24 rotates, it will drive the moving block 25 to move back and forth along the base 2. A moving rod 26 is fixedly connected to the upper end of the moving block 25. A support block 27 is slidably connected to the lower end of the platform 4. The support block 27 is rotatably connected to the moving rod 26. When the moving block 25 moves, it will push the platform 4 to rotate.

[0025] The working principle of this utility model is as follows: When the device is needed, the entire device can be placed in a designated position and supported by the support column 16. When the tensioning height needs to be adjusted, the bidirectional motor 7 starts working. When the bidirectional motor 7 is working, it drives the rotating rod 24 to rotate, thereby pushing the moving block 25 to move along the base 2. When the moving block 25 moves, it drives the moving rod 26 to rotate, thereby pushing the platform 4 to rotate through the support block 27, thus realizing the adjustment of the tensioning height and improving the practicality of the device. When the device is not needed to move it, the connecting rod 19 can be pulled outward by the pull ring 22. When the connecting rod 19 moves, it drives the first limiting block 20, the second limiting block 21, and the limiting strip 23 to move. At this time, the second limiting block 21 will enter the corresponding limiting groove on the second connecting wheel 10. In the middle, the limiting strip 23 will move from the groove on the support base 1, so that the support base 1 loses its limiting of the connecting rod 19. At this time, the bidirectional motor 7 will work again, thereby driving the first connecting wheel 8 to start working. Under the action of the belt 9, the second connecting wheel 10 will be driven to rotate, and then the rotating column 11 will drive the gear 12 to rotate. When the gear 12 rotates, it will drive the toothed plate 14 to move upward along the support rod 13. While the toothed plate 14 moves upward, it will drive the first connecting frame 15 and the support column 16 to retract into the support base 1, so that the pulley 18 contacts the ground. At this time, the device can be easily moved through the pulley 18. After the movement is completed, the bidirectional motor 7 rotates in the opposite direction, thereby pushing the support column 16 out again so that it contacts the ground. Finally, the connecting rod 19 is pushed back by the pull ring 22, thus completing the fixation of the support column 16.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
