SUMMARY

DETAILED DESCRIPTION

[0037] The following will be described in detail in combination with the accompanying Figures 1-5 The present application will be further described in detail.

[0038] Embodiment I

[0039] The first embodiment of the present application discloses a prefabricated assembly horizontal component levelness adjusting device, as shown in Figure 1As shown, it comprises a base 1, which is in the shape of a cylinder, and the lower end face of the base 1 is fixedly provided with a non-slip pad 40, which can reduce the possibility of the base 1 slipping and increase the stability of the support of the base 1. The upper end face of the base 1 is fixedly welded with a support rod 2, which is in the shape of a cylinder and whose axis extends in the vertical direction. The support rod 2 is slidably provided with an adjusting rod 4, which is in the shape of a cylinder and whose axis is on the same straight line as the axis of the support rod 2. The top end of the adjusting rod 4 is fixedly welded with a fixed disc 5, which is in the shape of a cylinder and whose center is on the same straight line as the center of the adjusting rod 4. The support rod 2 is provided with an adjusting assembly 6 for adjusting the elevation of the fixed disc 5. A supporting disc 7 is provided above the fixed disc 5, which is in the shape of a cylinder and whose center is on the same straight line as the center of the fixed disc 5. The fixed disc 5 is provided with an adjusting mechanism 8 for supporting and adjusting the levelness of the supporting disc 7, and the supporting disc 7 is supported on the horizontal prefabricated component. The worker adjusts the height of the supporting disc 7 through the adjusting assembly 6, so as to adjust the elevation of the horizontal prefabricated component. Then, the worker accurately adjusts the levelness of the supporting disc 7 through the adjusting mechanism, so as to accurately control the levelness of the horizontal prefabricated component.

[0040] As shown in Figure 1 and Figure 2 The adjusting assembly 6 comprises a first motor 9, a turbine 10, a worm 11 and a threaded sleeve 12. The upper end face of the support rod 2 is provided with an expansion slot 3 in the vertical direction, and the adjusting rod 4 is slidably arranged in the expansion slot 3. The top side wall of the support rod 2 is fixedly welded with a placing disc 41, and the upper end face of the placing disc 41 is fixedly welded with a bracket. The first motor 9 is fixedly installed on the side wall of the bracket. The threaded sleeve 12 is rotatably arranged on the upper end face of the support rod 2 and is threadedly connected to the adjusting rod 4. The turbine 10 is fixedly sleeved on the outer side wall of the threaded sleeve 12. The worm 11 is fixedly connected to the rotating shaft of the first motor 9 through a shaft coupling, and the turbine 10 and the worm 11 are engaged. The bottom side wall of the adjusting rod 4 is fixedly welded with a first limiting block 13, and the inner wall of the expansion slot 3 is provided with a first limiting slot 14 in the vertical direction. The first limiting block 13 is slidably arranged in the first limiting slot 14, and the first limiting slot 14 defines the movement track of the first limiting block 13. When the first motor 9 drives the adjusting rod 4 to rotate through the turbine 10, the worm 11 and the threaded sleeve 12, the rotation of the adjusting rod 4 can be limited, so that the adjusting rod 4 moves along its axis, thereby adjusting the elevation of the horizontal prefabricated component.

[0041] As shown in Figure 1 and Figure 3As shown, the adjusting mechanism 8 includes three sets of adjustable components 15, which are distributed in a triangular shape on the supporting tray 7, and each adjustable component 15 can be independently adjusted in height. The three sets of adjustable components 15 can be finely adjusted in multiple angles according to the requirements of the horizontal degree of the horizontal prefabricated component. The adjustable component 15 includes an adjusting screw 16 and a nut 17. The lower end surface of the supporting tray 7 is provided with three mounting holes, which are arranged in a triangular shape. The top of the adjusting screw 16 is connected to the mounting hole through a spherical hinge. The spherical hinge can facilitate the rotation of the adjusting screw 16 in the mounting hole, thereby reducing the restriction of the other two adjusting screws 16 on the third adjusting screw 16. The nut 17 is rotated on the fixed disc 5 and is threadedly connected to the adjusting screw 16. The fixed disc 5 is provided with three sliding grooves 18 in the vertical direction. The three adjusting screws 16 are respectively arranged in and slide in the sliding grooves 18. The inner wall of the sliding groove 18 is fixedly welded with a second limiting block 19, which is integrally formed with the fixed disc 5. The side wall of the adjusting screw 16 is provided with a second limiting groove 42 for the sliding of the second limiting block 19 in the vertical direction. The second limiting block 19 can limit the rotation of the adjusting screw 16. The workers can adjust the height of the three adjusting screws 16 by respectively rotating the three nuts 17, thereby adjusting the inclination direction and inclination angle of the supporting tray 7 according to the horizontal degree requirements of the horizontal prefabricated component. The bottom of the adjusting screw 16 is fixedly welded with an abutting block 20, which has a diameter larger than that of the adjusting screw 16. The abutting block 20 can abut against the lower end surface of the fixed disc 5, thereby limiting the movement range of the adjusting screw 16 and avoiding the possibility of the adjusting screw 16 being separated from the fixed disc 5.

[0042] The implementation principle of the embodiment one of the present application is as follows: during the production and installation of the prefabricated horizontal component, the inclined horizontal prefabricated component or the installation of the horizontal prefabricated component may occur. Therefore, in the present embodiment, the workers first place the device at a suitable position and then place the horizontal prefabricated component on the supporting tray 7 when installing the horizontal prefabricated component. Then, the workers start the first motor 9, which drives the worm 11 to rotate, and the worm 11 drives the turbine 10 to rotate, and the turbine 10 drives the threaded sleeve 12 to rotate. Under the limitation of the first limiting block 13, the threaded sleeve 12 drives the adjusting rod 4 to move linearly in the vertical direction, thereby adjusting the elevation of the horizontal prefabricated component according to the installation requirements, which is convenient for installation. After the elevation is roughly adjusted, the workers rotate the nut 17, which drives the adjusting screw 16 to move in the vertical direction under the limitation of the second limiting block 19, thereby adjusting the inclination direction and inclination angle of the supporting tray 7, and further improving the precision of the horizontal degree in the installation process of the horizontal prefabricated component.

[0043] Embodiment two

[0044] As Figure 4As shown, the difference between the second embodiment and the first embodiment is that the upper end face of the supporting tray 7 is provided with a placing groove 21 along one of its diameters, two groups of clamping pieces 22 are slidably arranged in the placing groove 21 along the extending direction thereof, and a driving assembly 23 for driving the clamping pieces 22 to move is arranged in the placing groove 21. The driving assembly 23 comprises a second motor 24 and a screw rod 25. The second motor 24 is fixedly installed on the peripheral side wall of the supporting tray 7. The screw rod 25 is provided with bidirectional threads at both ends thereof with the middle as a boundary. The two ends of the screw rod 25 are respectively rotatably connected to the opposite inner walls of the placing groove 21, and one of the segments is fixedly welded to the rotating shaft of the second motor 24. The clamping piece 22 comprises a sliding block 26 and a clamping block 27. The sliding block 26 is threadedly connected to the screw rod 25. The bottom of the clamping block 27 is hingedly connected to the top of the sliding block 26. The upper end face of the sliding block 26 is provided with a hinge groove 29. A rotating rod is rotatably arranged in the inner wall of the hinge groove 29. The bottom of the clamping block 27 is fixedly welded to the rotating rod. The clamping block 27 can be folded in the placing groove 21. The clamping block 27 is provided with a fixing assembly 30 for fixing itself.

[0045] As shown in Figure 4 , rubber pads 28 are fixedly adhered to the opposite side walls of the two clamping blocks 27. The rubber pads 28 are zigzag-shaped. After the clamping blocks 27 are rotated to be perpendicular to the end face of the supporting tray 7 and the positions of the clamping blocks 27 are fixed by the fixing assembly 30, the horizontal prefabricated component is placed on the supporting tray 7. Then, the worker starts the second motor 24. The second motor 24 is started to drive the screw rod 25 to rotate. The rotation of the screw rod 25 can drive the two sliding blocks 26 to move towards each other and drive the two clamping blocks 27 to approach and abut against the horizontal prefabricated component, so as to fix the horizontal prefabricated component, thereby reducing the possibility of displacement of the horizontal prefabricated component on the supporting tray 7 during installation and construction. When the horizontal prefabricated component is clamped, the rubber pads 28 can not only increase the friction between the clamping blocks 27 and the horizontal prefabricated component, but also reduce the possibility of damage to the surface of the horizontal prefabricated component caused by clamping.

[0046] As shown in Figure 4 and Figure 5As shown, the fixing assembly 30 comprises a fixing block 31, a pulling block 32, a first spring 33 and a second spring 34. The dovetail groove 35 is formed on the side wall of the clamping block 27 away from the rubber pad 28. The fixing block 31 slides in the dovetail groove 35 and reduces the possibility of the fixing block 31 from being separated from the dovetail groove 35. The fixing groove 36 is formed on the sliding block 26, and the fixing block 31 can be inserted into the fixing groove 36. The first spring 33 is arranged in the dovetail groove 35, and the two ends of the first spring 33 are fixedly welded to the side wall of the fixing block 31 and the inner wall of the dovetail groove 35, respectively. The storage groove 37 is formed on the fixing block 31, and the pulling block 32 slides in the storage groove 37. The second spring 34 is arranged in the storage groove 37, and the two ends of the second spring 34 are fixedly welded to the side wall of the pulling block 32 and the inner wall of the storage groove 37, respectively. The rail 38 is arranged in the dovetail groove 35, and the two ends of the rail 38 are fixedly welded to the opposite inner walls of the dovetail groove 35. The inclined surface 39 is arranged on the pulling block 32, and the inclined surface 39 abuts against the rail 38.

[0047] As shown in Figure 4 and Figure 5 When the clamping block 27 does not need to fix the horizontal prefabricated component or the prefabricated component is larger than the supporting tray 7, the worker rotates the clamping block 27 to fold it in the placing groove 21, thereby reducing the influence of the clamping block 27 on the placement of the horizontal prefabricated component. At this time, the pulling block 32 abuts against the side of the rail 38 away from the sliding block 26, the fixing block 31 compresses the first spring 33 and is completely in the dovetail groove 35, thereby reducing the possibility that the fixing block 31 extends out of the dovetail groove 35 to abut against the inner wall of the placing groove 21 under the action of the first spring 33 and affects the next rotation. When the clamping block 27 fixes the horizontal prefabricated component, the worker first rotates the clamping block 27 to be perpendicular to the supporting tray 7, and then pushes the pulling block 32 to compress the second spring 34 and move it into the storage groove 37. When the pulling block 32 is completely in the storage groove 37 and does not abut against the rail 38, the fixing block 31 is pushed by the second spring 34 to insert into the fixing groove 36, thereby fixing the position of the clamping block 27 and reducing the possibility of rotation. When the worker needs to fold the clamping block 27 after the construction is completed, the worker pushes the pulling block 32 to drive the fixing block 31 to compress the first spring 33 and move. When the pulling block 32 abuts against the rail 38, the rail 38 abuts against the inclined surface 39 on the pulling block 32 and pushes the pulling block 32 to compress the second spring 34 and move. When the pulling block 32 passes the rail 38, the pulling block 32 extends out of the storage groove 37 under the action of the second spring 34 and abuts against the rail 38, thereby reducing the extension of the fixing block 31 out of the dovetail groove 35.

[0048] When the clamping block 27 is folded in the placing groove 21, the fixing block 31 compresses the first spring 33, and the pulling block 32 on the fixing block 31 abuts against the rail 38. When the worker rotates the clamping block 27 to be perpendicular to the supporting tray 7, the worker pushes the pulling block 32 to compress the second spring 34 and move, thereby avoiding the rotation of the clamping block 27;

[0049] The implementation principle of the second embodiment of the present application is as follows: in order to reduce the possibility of the horizontal prefabricated component supported on the supporting tray 7 from being deviated or falling off during the installation process, the worker rotates the clamping block 27 to be perpendicular to the supporting tray 7 and fixes it through the fixing assembly 30, and then the worker can drive the two clamping blocks 27 to move towards each other through the driving assembly 23 and clamp and fix the horizontal prefabricated component on the supporting tray 7, thereby reducing the possibility of the horizontal prefabricated component from being deviated or falling off during the adjustment of the horizontal prefabricated component.

[0050] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application, so: all equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
