The adjusting screw is threadedly connected to the first leveling plate, and the lower surface of the adjusting screw is supported on the upper surface of the second leveling plate. The connecting screw is threadedly connected to both the first and second leveling plates.
[0009] In a preferred embodiment, the linear motion mechanism includes a movable plate for mounting the flipping mechanism, a slider and a guide rail disposed between the movable plate and the upper plate, and an electric push rod disposed on one side of the movable plate and mounted on the upper plate, the electric push rod being used to push the movable plate to move along the guide rail.

Detailed Implementation
[0032] Please see Figure 1-9 As shown, this application provides a technical solution: a substation prefabricated foundation beam positioning support, including a lifting mechanism 2 set on the ground, a linear moving mechanism 3 set above the lifting mechanism 2, and a flipping mechanism 4 set on the linear moving mechanism 3. The lifting mechanism 2 is used to raise the height of the foundation beam 12 in the vertical direction, the linear moving mechanism 3 is used to move the foundation beam 12 in the horizontal direction, and the flipping mechanism 4 is used to flip the angle of the foundation beam 12.
[0033] Positioning supports are set between two foundation columns 11. Two supports can be set next to the foundation columns 11 for the installation of the intermediate foundation beam 12. The positioning supports are equivalent to adjusting the height, level and angle of the foundation beam 12 except for the height direction, so that the steel nodes of the foundation beam 12 are completely aligned with the rigid nodes of the foundation column 11, which facilitates the connection of the rigid nodes later.
[0034] In a preferred embodiment, the lifting mechanism 2 includes an upper plate 21, a lower plate 22, and a first cross plate 23 and a second cross plate 24 that are disposed between the upper plate 21 and the lower plate 22 and hinged to each other. One end of the first cross plate 23 is hinged to the lower part of the upper plate 21, and the other end slides on the lower plate 22. One end of the second cross plate 24 is hinged to the lower plate 22, and the other end slides on the lower surface of the upper plate 21. The first cross plate 23 and the second cross plate 24 are arranged in pairs. A first horizontal shaft 25 is provided between the two first cross plates 23, and a second horizontal shaft 26 is provided at the hinge position of the two second cross plates 24. A hydraulic cylinder 27 is provided between the first horizontal shaft 25 and the second horizontal shaft 26. The base of the hydraulic cylinder 27 is hinged to the second horizontal shaft 26, and the extension rod of the hydraulic cylinder 27 is hinged to the first horizontal shaft 25.
[0035] In this way, the hydraulic cylinder 27 extends, pushing the first cross plate 23 and the second cross plate 24 to close. The upper plate 21 begins to move upward relative to the lower plate 22. The hydraulic cylinder 27 retracts, and the upper plate 21 begins to descend, realizing the upward and downward movement of the lifting mechanism 2.
[0036] In a preferred embodiment, a roller 28 is provided on the side where the first cross plate 23 and the second cross plate 24 slide, and a roller groove 211 is provided at the corresponding position below the upper plate 21 and above the lower plate 22, and the roller 28 rolls in the roller groove 211; a reinforcing plate 29 is also provided on the two first horizontal shafts 25 near the roller 28.
[0037] The roller 28 is designed to facilitate better movement of the first cross plate 23 and the second cross plate 24 on one side, changing sliding friction to rolling friction. The groove 211 can also serve as a guide.

The connecting screw 54 is threadedly connected to the first leveling plate 51 and the second leveling plate 52.
[0039] The principle of using the leveling device 5 is to first adjust the adjusting screw 53 so that the first adjusting plate 51 and the second adjusting plate 52 maintain a certain height difference, and then tighten the connecting screw 54 so that the leveling device 5 forms a whole. The purpose of setting up the leveling device 5 is to level the lifting mechanism 2 as a whole and prevent the equipment from tipping over due to instability of the center of gravity.
[0040] In a preferred embodiment, the linear motion mechanism 3 includes a movable plate 32 for mounting the flipping mechanism 4, a slider 33 and a guide rail 34 disposed between the movable plate 32 and the upper plate 21, and an electric push rod 35 disposed on one side of the movable plate 32 and mounted on the upper plate 21.

An opening 451 for accommodating the foundation beam 12 is provided in the turntable 45. A second sprocket 46 is also provided at the position corresponding to the motor 42 on the turntable 45. The motor 42 is connected to the first sprocket 43 and the second sprocket 46 through a chain 47, driving the turntable 45 to roll on the guide components 44, thereby causing the foundation beam 12 to flip.
[0043] The U-shaped frame 41 facilitates the placement of the foundation beam 12 into the turntable 45 from above. The turntable 45 is supported between the guide components 44. The motor 42 drives the first sprocket 43 and the second sprocket 46, and the turntable 45 rolls along the outer surface of the guide components 44, thereby realizing the flipping of the foundation beam 12.
[0044] In the preferred embodiment, there are two rotary tables 45, which are symmetrically arranged on both sides of the rectangular frame 41, and a connecting rod 48 is provided between the two rotary tables 45; a support plate 49 for supporting the foundation beam 12 is also provided below the opening 451 of the rotary table 45.

[0048] The clamping device 6 can clamp the foundation beam 12 from both the left and right sides to prevent the foundation beam 12 from moving within the rotary table 45.
[0049] A method for using positioning supports for prefabricated foundation beams in substations includes the following steps:
[0050] S1, Install and position the foundation column 11 on site;
[0051] S2, place the positioning support between the two foundation columns 11, and keep the opening 451 of the turntable 45 facing upwards;
[0052] S3, lower the foundation beam 12 from above the opening 451 onto the support plate 49 of the rotary table 45, and control the clamping device 6 to clamp and position the foundation beam 12.
[0053] S4 controls the lifting mechanism 2 of the positioning support to move upward, controls the linear movement mechanism 3 to move, and controls the flipping mechanism 4 to move, so that the steel node of the foundation beam 12 and the steel node of the foundation column 11 are completely aligned, which facilitates the secondary pouring of concrete for the steel node of the foundation beam 12 and the precast column steel node in the later stage.
[0054] S5. After the foundation beam 12 and foundation column 11 are poured, the controller releases the clamping device 6 and controls the lifting mechanism 2 of the positioning support to move downward.
