[0034] Example 1

[0035] In order to speed up the construction of the platform and reduce the requirements for the ground during construction, please refer to Figure 1-Figure 2 As shown, the purpose of this embodiment is to provide an adjustable overhead base for construction, including a base platform 1, on which a plurality of adjusting legs 2 are arranged, and the plurality of adjusting legs 2 can position the base platform 1, and can also support the base platform 1, and adjust the horizontal height of the base platform 1, so that the base platform 1 can adjust the height according to the corresponding site conditions, and it is convenient for the base platform 1 to receive the receiving object, and the adjusting legs 2 are stored inside the base platform 1. When the adjusting legs 2 are opened in a direction away from the base platform 1, the plurality of adjusting legs 2 cooperate with each other to position the base platform 1, and at the same time, the adjusting legs 2 provide corresponding support according to the position where the base platform 1 is set, so that the plurality of adjusting legs 2 locates the position of the base platform 1, and controls the positions of the plurality of adjusting legs 2 to support and fix the base platform 1 with the plurality of adjusting legs 2, so that the base platform 1 can adjust the height and placement form of the base platform 1 according to the conditions of the site and the installation conditions of the site, so as to facilitate the support of the base platform 1 to the receiving object. At the same time, a positioning member 3 is arranged on the base platform 1, and the positioning member 3 locates the positions of the plurality of adjusting legs 2 and fixes the positions of the adjusting legs 2 on the base platform 1. At the same time, by adjusting the position of the positioning member 3 on the base platform 1, the height of the base platform 1 supported by the adjusting legs 2 is changed, so as to facilitate the construction of the platform, avoid the need to level the site before building the platform, and speed up the construction of the platform.

[0036] The following is a detailed description of the above structure, please refer to Figure 1-Figure 8 As shown, the base platform 1 includes a base block 11, which is a polyhedron. At the same time, a plurality of storage grooves 12 are opened on the side wall of the base block 11. The storage grooves 12 pass through the top and bottom of the base block 11. The adjustment leg 2 includes a flip rod 21, which is arranged inside the storage groove 12, and one end of the flip rod 21 is hinged on the side wall of the storage groove 12 near the bottom. At this time, one end of the flip rod 21 can rotate around the position where it is hinged with the base block 11, so that one end of the flip rod 21 extends out of the storage groove 12. When the flip rod 21 is as shown in FIG. Figure 3 In the state shown, the flip rod 21 is in contact with the ground. The flip rod 21 is in contact with the ground to improve the stability of the base block 11 placed on the ground. This state is used when the ground is flat.

[0037] In order to fix the position of the flip rod 21, a hinge rod 23 is arranged on one side of the flip rod 21 close to the center of the base block 11, and one end of the hinge rod 23 is hinged at the middle position of the flip rod 21. A fixing column 13 is fixed at the upper end of the base block 11, and a plurality of side bars 14 are fixedly connected to the side wall of the fixing column 13. The positions of the side bars 14 and the storage grooves 12 correspond. The side walls of the storage grooves 12 and the side bars 14 are provided with sliding grooves 15, and a slider 24 is slidingly arranged in the sliding grooves 15. The other end of the hinge rod 23 is hinged on the slider 24. When one end of the flip rod 21 flips toward the direction away from the center of the base block 11, the flip rod 21 pulls the hinge rod 23 to make the hinge rod 23 pull the slider 24 to slide in the sliding groove 15. In the process of the slider 24 sliding down, the hinge rod 23 is blocked, so that the hinge rod 23 supports the flip rod 21, so that the flip rod 21 is easy to position.

[0038] In order to further fix the position of the flip rod 21 so that the flip rod 21 can stably position and support the base block 11, the structure of the positioning member 3 is refined, wherein the positioning member 3 includes a plurality of sliding blocks 31 in an annular array, wherein the plurality of sliding blocks 31 are connected by a pasting plate 32, wherein the plurality of sliding blocks 31 and the pasting plate 32 are combined to form a ring, wherein the sliding block 31 is slidably arranged in the storage groove 12, and the pasting plate 32 is in contact with the side wall of the base block 11, and the pasting plate 32 is fixed to the side wall of the base block 11 by screws, and the pasting plate 32 is fixed to the base block 11 by squeezing the side wall of the base block 11 when the screws are tightened. At the same time, a retaining groove 33 is provided on the sliding block 31, which passes through the bottom of the sliding block 31. The top of the retaining groove 33 is tilted downward toward a position away from the center of the base block 11, and the retaining groove 33 blocks the hinge rod 23 to fix the position of the hinge rod 23. At the same time, a retaining block 34 is fixed at a position on the top of the sliding block 31 close to the center of the base block 11. The retaining block 34 is arranged just above the sliding block 24 extending out of the sliding groove 15. When the sliding block 24 moves upward, the retaining block 34 presses and blocks the sliding block 24, so that the sliding block 24 cannot move upward. The sliding block 24 that cannot move upward positions the hinge rod 23, so that the hinge rod 23 stably supports the flip rod 21.

[0039] The flip rod 21 is stably supported by the positioning member 3 to fix the position of the flip rod 21, so that the flip rod 21 can stably position the position of the base block 11. At the same time, a threaded column 16 is fixed at the upper center position of the fixed column 13. The central axis of the threaded column 16 and the central axis of the fixed column 13 are on the same axis. An eccentric column 17 is threadedly connected to the threaded column 16. The central axis of the eccentric column 17 and the central axis of the threaded column 16 are not on the same axis. When the eccentric column 17 rotates on the threaded column 16, the eccentric column 17 rotates eccentrically, and during the rotation of the eccentric column 17, the eccentric column 17 moves upward, and the moving eccentric column 17 lifts the receiving object.

[0040] Considering that when the eccentric column 17 lifts up the receiving object, it receives a small plate-like structure, which is used to build a platform off the ground. At this time, the eccentric column 17 can change the height of the supported position of the plate-like structure by moving up and down, so that the plate is made in a horizontal state. When receiving a large-volume building, such as a pole frame for a suspended ceiling, a power tower, etc., it is necessary to use multiple bases for receiving. After receiving, the building needs to be debugged horizontally. During the debugging process, there is a situation where a little more adjustment will make it not level. At this time, the workers need to perform repeated debugging, which increases the difficulty of debugging for the workers. In order to reduce the difficulty of debugging for the workers, a connecting column 18 is fixed at the eccentric position of the top of the eccentric column 17. A connecting block is installed on the connecting column 18. The connecting block is connected to the receiving object and is replaced according to the support type of the receiving object. The building is received by the connecting column 18. When the eccentric column 17 rotates, the connecting column 18 rotates below the building. During the rotation of the connecting column 18, the position of the connecting column 18 supporting the building changes, such as Fig. 9 As shown, the solid line part is the state of the connecting column 18 supporting the building before it rotates, and the dotted line part is the state of the connecting column 18 supporting the building after it rotates. When the eccentric column 17 rotates and moves upward, the connecting column 18 lifts the support upward. At this time, the connecting column 18 changes the support point for the building, so that the building is lifted, and the height of the building is finely adjusted. When the eccentric column 17 rotates downward, the connecting column 18 changes the support point for the building, so that one side of the building also moves downward. By changing the point of support for the building by the connecting column 18, the amplitude of the up and down movement of the building during the rotation of the eccentric column 17 is reduced, the effect of the device on fine-tuning the height of the building is improved, and the difficulty of workers adjusting the level of the building is reduced.

[0041] At the same time, different connection blocks are installed according to the different types of objects supported by the connection column 18. There are two types of connection blocks, one of which is as follows Figure 1 The flat block 4 shown in the figure has a central axis of the flat block 4 and a central axis of the eccentric column 17 that are in the same straight line. The flat block 4 is used to receive and install the plate for building the platform. Figure 2The top connecting block 5 shown is installed and connected through the top connecting block 5 when leveling and installing a large building. The top connecting block 5 and the building are supported. During the rotation of the eccentric column 17, the top connecting block 5 moves together with the connecting column 18 to facilitate the connecting column 18 to change the supporting point of the building. After adjustment, the top connecting block 5 is fixed to the building.

[0042] When the ground is uneven, the flip rod 21 controls the flip angle according to the site where the base block 11 is set. The flip rod 21 after rotation and the vertical plane of the storage groove 12 are obtuse. Figure 4 As shown, after the flipping position is determined, the positioning is performed through the positioning member 3. After the position of the flipping rod 21 is fixed, a plurality of flipping rods 21 are in contact with the ground. The flipping rods 21 make a small area of ​​contact with the ground to reduce the impact of the uneven ground on the base block 11, so as to ensure that the base block 11 can be designed horizontally. In order to improve the horizontal setting of the device on the ground with different inclinations, the flipping rod 21 is set in a U shape, and a sliding rod 22 is slidably provided inside the flipping rod 21. The internal thread of the sliding rod 22 is connected with a screw rod 25. One end of the screw rod 25 is rotatably set inside the flipping rod 21, and one end of the screw rod 25 set inside the flipping rod 21 is provided with a gear set 26. The gear set 26 It is composed of two bevel gears, one of which is fixedly connected to one end of the screw 25, and one end of the other bevel gear extends out of the side wall of the flip rod 21. When the gear set 26 rotates, it drives the screw 25 to rotate. When the worker uses a hand drill to drive the gear set 26 to rotate, the gear set 26 drives the screw 25 to rotate, so that the screw 25 drives the sliding rod 22 to extend or retract, so that the length of the adjusting leg 2 is adjusted according to the depression of the ground to ensure the horizontal setting of the base block 11. At the same time, when the base platform 1 is installed on an inclined surface, the length of the adjusting leg 2 can be adjusted to make the central axis of the base block 11 perpendicular to the inclined surface, so as to facilitate the installation of the receiving object on different grounds.

[0043] The height of the base platform 1 is roughly adjusted by adjusting the legs 2 so that the base platform 1 is at a suitable height, and then the eccentric column 17 is rotated to make the base platform 1 fine-adjust the height of the receiving object to ensure the horizontality of the supported object. The rough adjustment of the height of the base platform 1 by adjusting the legs 2 and the fine adjustment of the eccentric column 17 eliminates the requirement for ground flatness during the construction of the platform or building, and eliminates the workers from leveling the ground when building the platform or building, thereby speeding up the construction of the platform or building. By eccentrically setting the eccentric column 17, when the platform is built, the flat block 4 is used to connect the platform, and then the angle of the adjusting leg 2 is adjusted to control the height of the platform. When the building is built, the top connecting block 5 is used to support the building, and then the eccentric column 17 is rotated to change the position of the top connecting block 5 behind the building, so as to change the inclination angle of the building, so as to achieve the effect of fine-tuning the horizontality of the building, so as to ensure the stability of the building construction.
