For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] like Figures 1-2 As shown, this utility model provides a fine-tuning and pressing device for prefabricated turnout slabs of ballastless track assembly, including a base 16 and a turnout prefabricated slab 1. The base 16 is provided with multiple pressing devices 2 and multiple fine-tuning devices. The pressing devices 2 are used to press the turnout prefabricated slab 1. The fine-tuning device includes a mounting block 8 and a connecting plate 14. The connecting plate 14 is detachably connected to the turnout prefabricated slab 1. An elevation fine-tuning block 13 is provided on one side of the outer wall of the connecting plate 14. An elevation fine-tuning rod 12 is internally threaded to the elevation fine-tuning block 13. The elevation fine-tuning rod 12 is rotatably connected to the top of the mounting block 8. A fine-tuning base 9 is provided on the top of the base 16 on one side of the mounting block 8. The fine-tuning base 9 is provided with a sliding slider 17 and a first fine-tuning rod 11 for pushing the slider 17 to slide. The slider 17 is slidably connected to the mounting block 8. A second fine-tuning rod 10 is provided on the slider 17 for pushing the mounting block 8 to slide.

[0028] Specifically, when fine-tuning and tightening of the turnout precast slab 1 is required, firstly, multiple connecting plates 14 are installed on one side of the turnout precast slab 1, thereby installing multiple fine-tuning devices on the turnout precast slab 1. Then, the turnout precast slab 1 is placed on top of the base 16. The multiple fine-tuning devices work together to support the turnout precast slab 1. After measuring with a total station, the position of each fine-tuning device is determined. By rotating the elevation fine-tuning rod 12, the elevation fine-tuning block 13 moves relative to the elevation fine-tuning rod 12, thereby driving the elevation fine-tuning block 13 to rise and fall. Through the connecting plates 14, the turnout precast slab 1 is raised and lowered, thereby adjusting the turnout precast slab 1. The height can be adjusted by rotating the first fine-tuning rod 11 to drive the slider 17 to move longitudinally, and by rotating the second fine-tuning rod 10 to drive the mounting block 8 to move laterally, thus completing the fine-tuning of the position of the turnout precast slab 1. This utility model achieves fine-tuning of the elevation, direction, and longitudinal positioning of the turnout precast slab 1 by rotating the elevation fine-tuning rod 12, the second fine-tuning rod 10, and the first fine-tuning rod 11. After the fine-tuning of the turnout precast slab 1 is completed, when it is necessary to carry out anti-displacement and anti-floating work on the turnout precast slab 1, the clamping device 2 is first placed on the base 16 and positioned on one side of the turnout precast slab 1 to carry out anti-displacement and anti-floating work on the turnout precast slab 1.

[0029] This invention achieves fine adjustment of the elevation, direction, and longitudinal positioning of the turnout precast slab 1 by rotating the elevation fine adjustment rod 12, the second fine adjustment rod 10, and the first fine adjustment rod 11. Compared with the prior art, the fine adjustment work can be completed by simply installing the fine adjustment device on one side of the turnout precast slab 1, without the need for a fine adjustment frame. This invention has a small self-weight and is easy to disassemble and assemble, ensuring the working efficiency and use effect of the fine adjustment device.

[0030] In one embodiment, the fine-tuning base 9 is provided with a first upright plate 18, the first fine-tuning rod 11 is rotatably connected to the first upright plate 18, the first fine-tuning rod 11 is threadedly connected to the slider 17, the slider 17 is provided with a second upright plate 19, the second fine-tuning rod 10 is rotatably connected to the second upright plate 19, and the second fine-tuning rod 10 is threadedly connected to the mounting block 8.

[0031] Specifically, when the first fine adjustment rod 11 is rotated, the first upright plate 18 supports the first fine adjustment rod 11. When the first fine adjustment rod 11 rotates, it moves relative to the slider 17, thereby pushing the slider 17 to move. The second upright plate 19 supports the second fine adjustment rod 10. When the second fine adjustment rod 10 rotates, it moves relative to the mounting block 8, thereby driving the mounting block 8 to move.

[0032] like Figure 3As shown in one embodiment, the clamping device 2 includes a support plate 5, which is detachably connected to the base 16. A fixing plate 20 is provided on one side of the outer wall of the support plate 5. A vertical pressure rod 3 is threadedly connected to the inner side of the fixing plate 20 above the turnout precast slab 1. A pressure plate 4 is provided at the bottom end of the vertical pressure rod 3. The connecting plate 14 is detachably connected to the turnout precast slab 1 by multiple connecting bolts 15. The support plate 5 is detachably connected to the base 16 by multiple fixing bolts 7. Multiple clamping devices 2 are evenly distributed on both sides of the turnout precast slab 1. The outer walls of multiple clamping devices 2 located on the same side are provided with the same first template 21 near the turnout precast slab 1. A second template 22 is provided between the two first templates 21 on one side of the turnout precast slab 1. The support plate 5 is detachably connected to the first template 21 by multiple clamping bolts 6.

[0033] Specifically, after the fine-tuning of the precast turnout slab 1 is completed, when it is necessary to prevent displacement and floating of the precast turnout slab 1, firstly, the support plate 5 is placed on the concrete base 16. After effectively connecting it to the base 16 using the fixing bolts 7, the first template 21 is installed on one side of the multiple support plates 5 on the same side using the clamping bolts 6, so that the first template 21 fits against the bottom of the precast turnout slab 1, and at the same time, it plays a limiting role for the precast turnout slab 1; then, the transverse pressure bar 23 on the support plate 5 is adjusted so that one end of the transverse pressure bar 23 contacts the precast turnout slab 1, which helps to prevent displacement and floating of the precast turnout slab 1. The plate 1 acts as a limit and adjusts the vertical pressure bar 3 on the fixed plate 20, so that the vertical pressure bar 3 and the fixed plate 20 move relative to each other, thereby driving the pressure plate 4 to rise and fall. When the pressure plate 4 is in stable contact with the top of the turnout precast plate 1, the anti-floating work is achieved. Finally, two second templates 22 are installed between two adjacent first templates 21. The two first templates 21 and the two second templates 22 cooperate to block the gap between the bottom of the turnout precast plate 1 and the base 16, preventing concrete from entering the bottom of the turnout precast plate 1 during subsequent work, thus ensuring the working effect of the device.

[0034] This utility model, through the cooperation of support plate 5, vertical pressure rod 3, pressure plate 4 and horizontal pressure rod 23, can adjust the vertical pressure rod 3 to drive the pressure plate 4 to contact the top of the turnout precast slab 1, thus completing the anti-floating work. The horizontal pressure rod 23 and support plate 5 complete the limiting work of the turnout precast slab 1. Compared with the prior art, this utility model has a smaller self-weight and is easy to disassemble and assemble, ensuring the working efficiency and use effect of the pressing device 2.

[0035] In one embodiment, the fine-tuning device is placed on the base 16 using a fine-tuning base 9. In some embodiments, each fine-tuning device is connected to the turnout precast slab 1 by two connecting bolts 15. The connecting bolts 15 are made of stainless steel M24*185 to ensure a stable connection between the fine-tuning device and the turnout precast slab 1. The elevation fine-tuning rod 12 is made of M30*285 with a strength grade of 8.8, while the first fine-tuning rod 11 and the second fine-tuning rod 10 are made of M16 bolts with a strength grade of 8.8 to ensure the overall stability of the turnout precast slab 1.

[0036] In one embodiment, the clamping device 2 is connected to the base 16. In some embodiments, each clamping device 2 is connected to the concrete base by four φ12 fixing bolts 7. The fixing bolts 7 are made of YG2 type material M12×245, which can effectively prevent the turnout precast slab 1 from floating and shifting. The vertical pressure bar 3, the horizontal pressure bar 23, and the fixing bolts 7 are all made of M16 bolts with a strength grade of 8.8 to ensure mutual compatibility.

[0037] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
