The lower frame 3 is provided with a second slide groove 22, and a second slider 11 is slidably connected inside the second slide groove 22. A connecting rod 33 is fixedly connected to the second slider 11, and the other end of the connecting rod 33 is fixedly connected to the first slider 24. A sleeve 12 is fixedly connected to the second slider 11 for pre-fixing the reinforcing bar. The sleeve 12 is provided with a threaded hole 14, and a second bolt 13 is threaded inside the threaded hole 14, allowing the first slider 24 and the second slider 11 to move left and right through the connecting rod 33. A first threaded rod 16 is provided inside the first slide groove 23, and the first threaded rod 16 is threaded with the first slider 24. The machine is connected as follows: the right end of the first threaded rod 16 is fixedly connected to the first rotating handle 17, which can rotate the threaded rod; the upper frame 4 is provided with a third slide groove 28, and a third slider 27 is slidably connected inside the third slide groove 28; a fixing block 26 is fixedly connected to the third slider 27; a first hydraulic cylinder 25 is fixedly connected to the fixing block 26, which allows the clamping plate 21 to move up and down; the output end of the first hydraulic cylinder 25 is fixedly connected to the clamping plate 21, which is used to clamp the steel bar on the positioning seat 15; the third slide groove 28 is provided with a second threaded rod 19, which allows the slider to move left and right, and the second threaded rod 19 is threadedly connected to the third slider 27; the right end of the second threaded rod 19 is fixedly connected to the second rotating handle 18; the lower frame 3 is provided with scale lines 10 to observe the distance between the steel bars; and multiple support seats 2 are fixedly connected below the fixed seat 1 to support the entire machine.

[0019] Working principle: First, the entire positioning structure is placed at the designated construction position using multiple support seats 2 at the bottom. The support seats 2 ensure the overall stability of the fixed seat 1, preventing equipment shaking from affecting the positioning accuracy of the rebar during construction. Then, according to the required rebar laying height, multiple second hydraulic cylinders 30 on the lower inner wall of the fixed seat 1 are activated. Since the output end of the second hydraulic cylinder 30 is fixedly connected to the lower frame 3, the extension and retraction of the hydraulic cylinder will drive the lower frame 3 to rise and fall synchronously until the lower frame 3 is adjusted to a suitable height for rebar placement. Then, the second hydraulic cylinders 30 are closed, completing the height positioning of the lower frame 3. Next, the second bolt 13 on the sleeve 12 of the second slider 11 is loosened, and then the first rotating handle 17 on the right side of the lower frame 3 is rotated. This drives the first slider 24 to slide horizontally within the first groove 23, stopping rotation when adjusted to the appropriate position. Since the first slider 24 is fixedly connected to the second slider 11 via the connecting rod 33, the sliding of the first slider 24 will cause the second slider 11 to slide synchronously within the second groove 22, ensuring that the sleeve 12 and the positioning seat 15 always operate synchronously. Simultaneously, referring to the scale line 10 on the lower frame 3, the positioning seat 15 is adjusted to the preset spacing. After the spacing is adjusted, the reinforcing bars to be constructed are then passed through the sleeve 12 one by one and placed on the positioning seat 15. The protective pad 20 on the top of the positioning seat 15 can directly contact the reinforcing bars, preventing the surface of the reinforcing bars from being scratched by the hard contact of the positioning seat 15, while also reducing the contact between the reinforcing bars and the positioning seat. Slide between 15, then cover the upper frame 4 on top of the lower frame 3, aligning the upper fixing ear 5 of the upper frame 4 with the lower fixing ear 6 of the lower frame 3, and pass the first bolt 7 through the upper fixing ear 5 and the lower fixing ear 6 in sequence. Then, thread the nut 8 to the lower end of the first bolt 7 and gradually tighten the nut 8. At this time, the anti-slip pad 9 on the lower fixing ear 6 will be in close contact with the bottom of the upper fixing ear 5, increasing the friction to prevent the nut 8 from loosening. Then adjust the position of the clamp 21 and rotate the second rotating handle 18 on the right side of the upper frame 4. It is fixedly connected to the second threaded rod 19, and the second threaded rod 19 is threadedly connected to the third slider 27. Rotating the handle will drive the third slider 27 to slide horizontally in the third slide groove 28. The movement is initiated by a fixed block 26 connected to the third slider 27, which in turn is connected to the first hydraulic cylinder 25 and the clamping plate 21. As the third slider 27 slides, it synchronously moves the clamping plate 21 until it aligns with the reinforcing bar below, initiating the clamping action: the first hydraulic cylinder 25 is activated, its output end extending downwards, causing the clamping plate 21 to gradually approach the top of the reinforcing bar until it is in close contact with the surface of the reinforcing bar. After clamping, the first hydraulic cylinder 25 is closed, achieving precise positioning. The second bolt 13 on the sleeve 12 is then tightened to prevent the positioning seat 15 from shifting during subsequent reinforcing bar placement. Subsequent welding, binding, and other construction processes can then proceed. After the reinforcing bar construction is completed, the "reverse steps" are followed: first, the first hydraulic cylinder 25 is retracted to disengage the clamping plate 21 from the reinforcing bar; then, the nut 8 of the first bolt 7 is loosened, and the upper frame 4 is removed.Finally, the spacing of the positioning seats 15 can be adjusted as needed, or the lower frame 3 can be lowered via the second hydraulic cylinder 30 to complete the rapid reset or transfer of the equipment.
