[0027] like Figure 1-4 As shown, the utility model provides a variable diameter pile foundation steel cage hoop processing device, comprising a support base 1,

[0028] A stirrup diameter adjustment mechanism 2 is provided on the support base 1, and the stirrup diameter adjustment mechanism 2 includes a center rod 21, a slidable oblique rod 24, a fixed cross rod 25, a cross rod sleeve 26, and a bent vertical rod 27. The center rod 21 penetrates the support base 1 and is rotatably connected to the support base 1. The outer surface of the upper end of the center rod 21 is provided with an external thread, and the arc surface at the bottom of the center rod 21 is fixedly connected to the fixed cross rod 25, and the fixed cross rod 25 is slidably connected to the cross rod sleeve 26.

[0029] It should be noted that the number of the fixed cross bars 25 is several, and the several fixed cross bars 25 are equidistantly distributed in a ring with the center point of the center bar 21 as the center. Similarly, it can be known that the number of cross bar sleeves 26 on the several fixed cross bars 25 is also several, and the limiting rods 28 are arranged on the several cross bar sleeves 26, and the ideal number of the limiting rods 28 is two;

[0030] A power mechanism for the center rod 21 is provided on the inner side of the support base 1 (i.e., a servo motor connected to the center rod 21. By fixing the servo motor on the inner side of the support base 1 and fixing the output shaft of the servo motor to one end of the center rod 21 passing through the support base 1, the center rod 21 can be driven to rotate reciprocally by the servo motor).

[0031] In an optional embodiment, an adjustment member for adjusting the sliding diagonal rod 24 is provided on the center rod 21 shown; the adjustment member includes a nut 23 threadedly connected to the outer surface of the center rod 21, and the outer surface of the center rod 21 is slidably connected to a center sleeve 22, and one end of the sliding diagonal rod 24 away from the fixed cross rod 25 is ball-connected to the center sleeve 22.

[0032] It should be noted that the lower end of the nut 23 is fixedly connected to a slider having one end extending to the inside of the center sleeve 22. A sliding groove located on the outside of the slider is provided on the side of the center sleeve 22 close to the nut 23. The sliding groove is slidably connected to the slider, and the slider is T-shaped. The sliding groove is distributed in a ring shape, so that when the rotating nut 23 moves back and forth on the center rod 21, it can drive the center sleeve 22 to follow the up and down reciprocating movement, and the center sleeve 22 does not separate from the nut 23.

[0033] In this embodiment, when the processing diameter of the stirrups needs to be changed, the vertical height of the center sleeve 22 is adjusted so that the sliding inclined rods 24 on the center sleeve 22 drive the cross bar sleeve 26 on the fixed cross bar 25 to move horizontally, ensuring that the bent vertical rod 27 and the limit rod 28 fixedly connected to the cross bar sleeve 26 are moved to the required positions, thereby realizing rapid and uniform adjustment of the processing diameter of the stirrups.

[0034] In an optional embodiment, a guide device 3 is provided on the support base 1, including a guide wheel 33 for adjusting and guiding the diameter of the stirrup;

[0035] The guide device 3 further includes a guide rod 31 , the lower end of the guide rod 31 is fixed on the support base 1 , the upper end of the guide rod 31 is provided with a horizontal telescopic structure 32 , and the guide rod 31 is rotatably connected to the horizontal telescopic structure 32 .

[0036] It should be noted that the horizontal telescopic structure 32 is composed of a sleeve rod, a sliding rod and a locking screw. The sleeve rod is fixedly connected to the guide rod 31, the sliding rod is slidably connected to the inner side of the sleeve rod, and one end of the sliding rod located on the outer side of the sleeve rod is rotatably connected to the guide wheel 33. The locking screw is threadedly connected to the sleeve rod, and the sliding sliding rod is locked and fixed by the rotating locking screw against the sliding rod on the inner side of the sleeve rod.

[0037] In this embodiment, since the stirrup processing diameter can be flexibly adjusted, a horizontal telescopic structure 32 is provided at the upper end of the guide rod 31, which can be adjusted in time according to the stirrup diameter processing requirements to ensure that the guide wheel 33 provided at the end of the upper end of the horizontal telescopic structure 32 can fully exert the guiding effect on the stirrup.

[0038] The working principle of the above embodiment is:

[0039] The support base 1 is fixed to the ground, and the vertical height of the center sleeve 22 connected to the center rod 21 on the stirrup diameter adjustment mechanism 2 is adjusted according to the stirrup processing diameter requirements. After adjusting the position of the supporting center sleeve 22 by the nut 23, the cross bar sleeve 26 on the connected fixed cross bar 25 is driven to move horizontally by each slidable inclined rod 24 on the center sleeve 22. After moving the bent vertical rod 27 and the limit rod 28 fixedly connected to the cross bar sleeve 26 to the required position of the stirrup processing diameter, the length of the horizontal telescopic structure 32 in the guide device 3 is adjusted accordingly, so that the guide wheel 33 can be close to the steel bar to achieve effective guidance of the steel bar. After the stirrup diameter adjustment mechanism 2 and the guide device 3 are adjusted, the power supply of the power mechanism inside the support base 1 is started, and the rotation speed is adjusted to achieve efficient and high-quality processing of the pile foundation steel cage stirrups.
