[0037] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0038] like Figures 1-4 As shown, the present invention provides a precast slab adjustment device for the installation of a precast slab 100. The precast slab adjustment device includes a base 1 and a positioning structure 2. The base 1 includes a first rotating shaft 11 extending along a second direction. The positioning structure 2 includes a flip plate 21, a first driving mechanism 22, a second adjusting plate 23, and a third adjusting plate 24. The flip plate 21 is fixedly connected to the first rotating shaft 11 and configured to rotate relative to the base 1 about the first rotating shaft 11. The third adjusting plate 24 is configured to move relative to the flip plate 21 along a third direction. The second adjusting plate 23 is slidably mounted on the third adjusting plate 24 and configured to move relative to the third adjusting plate 24 along the second direction. The first driving mechanism 22 is connected to the second adjusting plate 23. The precast slab 100 is detachably connected to the first driving mechanism 22, which is configured to drive the precast slab 100 to move along a first direction. Any two of the first, second, and third directions are perpendicular to each other.

[0039] The first drive mechanism 22, the second adjustment plate 23, and the third adjustment plate 24 work together to enable the precast slab 100, which is detachably connected to the first drive mechanism 22, to be adjusted in the first, second, and third directions. This allows for high degree of freedom, flexibility, and versatility in adjustment. The flip plate 21 can adjust the level of the precast slab 100, allowing it to be installed on an inclined plane for easy installation.

[0040] Specifically, the base 1 also includes an angle adjustment mechanism 12, the output end of which is connected to the first rotating shaft 11. The angle adjustment mechanism 12 can drive the first rotating shaft 11 to rotate around its own axis. The aforementioned angle adjustment mechanism 12 enables the first rotating shaft 11 to drive the flip plate 21 to rotate, thereby achieving level adjustment of the precast slab 100 and reducing manual labor.

[0041] Optionally, in this embodiment, the angle adjustment mechanism 12 is a hydraulic motor commonly used in the art, and its specific principle and structure will not be described in detail here.

[0042] Specifically, the first drive mechanism 22 is configured as a hydraulic cylinder, and the output end of the first drive mechanism 22 is provided with a threaded section, to which the precast plate 100 is screwed. The aforementioned threaded section enables a detachable connection between the precast plate 100 and the first drive mechanism 22.

[0043] More specifically, three first drive mechanisms 22 are spaced apart and arranged in a triangular pattern. This arrangement makes the precast slab 100 more stable and prevents it from falling off.

[0044] More specifically, the output end of the first drive mechanism 22 is rotatably provided with a ball joint 221. The end of the ball joint 221 near the precast slab 100 is provided with a threaded section. Rotating the ball joint 221 can separate the precast slab 100 from the first drive mechanism 22, which is simple and convenient to operate.

[0045] Specifically, the positioning structure 2 also includes a second drive mechanism 25. The fixed end of the second drive mechanism 25 is fixedly connected to the side of the third adjusting plate 24 facing the second adjusting plate 23, and the output end is fixedly connected to the second adjusting plate 23. The second drive mechanism 25 can drive the second adjusting plate 23 to move relative to the third adjusting plate 24 in the second direction. The above-mentioned second drive mechanism 25 enables the position adjustment of the precast slab 100 in the second direction, reducing the amount of manual work.

[0046] More specifically, the second adjusting plate 23 has a first clearance notch extending through in the second direction. The second driving mechanism 25 extends into the first clearance notch, and the output end of the second driving mechanism 25 is fixedly connected to the inner wall of the first clearance notch. The aforementioned first clearance notch can prevent positional interference between the second driving mechanism 25 and the second adjusting plate 23.

[0047] Specifically, the third adjusting plate 24 has a limiting protrusion 241 protruding on the side near the second adjusting plate 23, and the second adjusting plate 23 has a sliding groove. The limiting protrusion 241 extends into the sliding groove to realize the sliding connection between the third adjusting plate 24 and the second adjusting plate 23.

[0048] More specifically, the distance between the two sidewalls of the slide groove in the third direction gradually increases with the increase of the slide groove depth, and the limiting protrusion 241 can fit against the sidewall of the slide groove. The above configuration can prevent the limiting protrusion 241 from separating from the slide groove in the first direction.

[0049] Optionally, in this embodiment, the second drive mechanism 25 is a linear hydraulic cylinder commonly used in the art, and its principle and structure will not be described in detail here. In other embodiments, the second drive mechanism 25 may also be other linear drive mechanisms, and no specific limitation is made here.

[0050] Specifically, the positioning structure 2 also includes a third drive mechanism 26. The fixed end of the third drive mechanism 26 is fixedly connected to the flip plate 21, and the output end is fixedly connected to the third adjustment plate 24. The third drive mechanism 26 can drive the third adjustment plate 24 to move relative to the flip plate 21 in a third direction. The aforementioned third drive mechanism 26 enables the precast slab 100 to be adjusted in a third direction, reducing the amount of manual labor.

[0051] Optionally, in this embodiment, the third drive mechanism 26 is a linear hydraulic cylinder commonly used in the art, and its principle and structure will not be described in detail here. In other embodiments, the third drive mechanism 26 may also be other linear drive mechanisms, and no specific limitation is made here.

[0052] Specifically, the positioning structure 2 also includes a positioning plate 27 and a second rotating shaft 28. The positioning plate 27 is slidably connected to the flip plate 21 at both ends. A clearance groove 240 is provided on the side of the third adjusting plate 24 facing away from the flip plate 21. The positioning plate 27 extends into the clearance groove 240 and abuts against the bottom of the groove. The second rotating shaft 28 extends along the first direction and is rotatably mounted on the positioning plate 27. One end of the second rotating shaft 28 is fixedly connected to the second adjusting plate 23, and the other end is fixedly connected to the third adjusting plate 24. Two third driving mechanisms 26 are spaced apart in the second direction and symmetrical about the second rotating shaft 28. The two third driving mechanisms 26 can drive the two ends of the second adjusting plate 23 to move in the same direction around the second rotating shaft 28. This arrangement allows the precast slab 100 to rotate around the second rotating shaft 28, thereby achieving angle adjustment on the common plane of the second and third directions.

[0053] More specifically, the flip plate 21 has two accommodating slots spaced apart in the second direction, and the positioning plate 27 has connecting portions 271 protruding from both ends in the second direction, with the connecting portions 271 extending into the accommodating slots one by one. The arrangement of the accommodating slots prevents the positioning plate 27 from interfering with the position of the connecting portions 271 and the flip plate 21.

[0054] More specifically, the flip plate 21 has a second clearance notch on the side facing the positioning plate 27, and the fixed end of the third drive mechanism 26 is fixedly connected to the inner wall of the second clearance notch. The above-mentioned second clearance notch can prevent the third drive mechanism 26 from interfering with the position of the third adjustment plate 24.

[0055] Specifically, the base 1 also includes a base plate 13 and pulleys 14. The first rotating shaft 11 is mounted on the base plate 13; the pulleys 14 are mounted on the base plate 13. The pulleys 14 facilitate the movement of the base 1.

[0056] Preferably, in this embodiment, the pulley 14 is a universal wheel structure with a self-locking function to ensure the flexibility of the base 1. Furthermore, during the positioning operation of the precast slab 100, the pulley 14 can achieve self-locking to prevent the base 1 from sliding during the operation. It should be noted that the pulley 14 described above is prior art disclosed in the art, and its principle and structure will not be elaborated here.

[0057] Specifically, a counterweight 15 is provided on the base 1. The aforementioned counterweight 15 can improve the stability of the precast slab 100 and the base 1 during the positioning process, preventing the base 1 from tipping over. It is understood that multiple other precast slabs 100 to be operated on can be used as counterweights 15 and placed on the base plate 13.

[0058] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
