When the first eccentric block 29 and the second eccentric block 30 rotate at high speed, the dual-axis motor 27 itself generates high-frequency vibration, which can make the steel cage body 3 generate high-frequency vibration, and make the concrete poured into the steel cage body 3 generate high-frequency vibration, so as to achieve the function of expelling the air inside the concrete, avoiding the presence of a large number of bubbles inside the concrete, resulting in low strength of the concrete after solidification into foundation piles.

[0033] like Figure 1 As shown, universal wheels 31 with braking function are provided at the four corners of the bottom of the base plate 1, and the universal wheels 31 are fixedly connected to the base plate 1 to facilitate users to move the device.

[0034] like Figure 1 As shown, batteries 32 are fixedly connected to both sides of the top of the base plate 1, and the dual-axis motor 27 and the motor 17 are electrically connected to the battery 32. The battery 32 can not only provide electrical energy for the dual-axis motor 27 and the motor 17, but can also be connected to the power source with wires, thereby improving the flexibility of the device.

[0035] Working principle: The user can rotate the adjusting knobs 23 at the four corners according to the undulation of the ground, and the adjusting knobs 23 drive the screw rod 22 to rotate. The screw rod 22 is lifted and lowered by the cooperation of the internal threaded sleeve 21 while rotating. The screw rod 22 is lifted and lowered while driving the connecting rod 24, and the connecting rod 24 drives the ground claw 26, thereby achieving the purpose of adjusting the height of the four corners of the base plate 1. The height of the four corners of the device can be adjusted according to the undulation of the ground so that the device itself remains in a horizontal state. Then start the motor 17, and the output end of the motor 17 drives the first rotating shaft 16, the first rotating shaft 16 drives the second bevel gear 15, the second bevel gear 15 drives the first bevel gear 14, and the first bevel gear 14 drives the flat screw disk 11 to rotate inside the correction box 6. When the flat screw disk 11 rotates, it pushes the moving block 12 through the flat thread on its surface, and the moving block 12 is moved by The correction box 6 is cooperated with to move toward the steel cage body 3, and the moving block 12 drives the correction clamp 7 while moving, so that the correction clamp 7 clamps and fixes the steel cage body 3 from four directions, thereby keeping the steel cage body 3 and the device in a vertical state, so as to achieve the purpose of correcting the steel cage body 3. The height of the four corners of the device can be adjusted according to the undulation of the ground, so that the device itself can be kept in a horizontal state before the steel cage body 3 is corrected, thereby improving the correction effect of the steel cage body 3, and solving the problem that the existing pile foundation steel cage inclination correction equipment can correct the steel cage, but it does not have the function of correcting the device itself. Since the ground of the construction site is generally undulating, the device itself will also tilt when it is placed on the ground, thereby making the device have a poor correction effect on the steel cage.

[0036] Start the dual-axis motor 27, and the output end of the dual-axis motor 27 drives the second rotating shaft 28. When the second rotating shaft 28 rotates, it drives the first eccentric block 29 and the second eccentric block 30 to rotate. When the first eccentric block 29 and the second eccentric block 30 rotate at high speed, the dual-axis motor 27 itself generates high-frequency vibrations, which can make the steel cage body 3 generate high-frequency vibrations, and make the concrete poured into the steel cage body 3 generate high-frequency vibrations, so as to achieve the function of expelling the air inside the concrete, avoiding the presence of a large number of bubbles inside the concrete, resulting in low strength of the concrete after solidification into foundation piles.

Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
