DETAILED DESCRIPTION

[0016] The technical solution of the utility model is further described in detail below in conjunction with specific implementation methods.

[0017] like Figures 1 to 3 As shown, in the embodiment of the utility model, a pile head 1 steel bar 6 positioning tool comprises a first positioning plate 3 and a second positioning plate 4, the first positioning plate 3 and the second positioning plate 4 are coaxially arranged from top to bottom in the vertical direction, the radial specification of the first positioning plate 3 is larger than the radial specification of the second positioning plate 4, a placement seat 2 is provided at the bottom of the second positioning plate 4, the circumferential sides of the first positioning plate 3 and the second positioning plate 4 are evenly provided with the same number of guide grooves, the guide grooves are used for the insertion of the pile head 1 steel bar 6, a plurality of groups of guide connecting rods 5015 are installed between the first positioning plate 3 and the second positioning plate 4, the guide connecting rods 5015 are used to position and guide the adjustment of the spacing between the first positioning plate 3 and the second positioning plate 4, a screw structure is installed between the first positioning plate 3 and the second positioning plate 4, the screw structure is used to adjust the spacing between the first positioning plate 3 and the second positioning plate 4;

[0018] Specifically, when realizing the bending positioning of the steel bar 6 of the pile head 1, the utility model is placed as a whole at the center of the steel bar 6 of the pile head 1, and the bottom placement seat 2 of the second positioning plate 4 is clamped on the pile head 1. At the same time, multiple groups of steel bars 6 of the pile head 1 are clamped in the guide grooves on the sides of the first positioning plate 3 and the second positioning plate 4 in sequence. After completing the limited clamping of the steel bars 6 of the pile head 1, the first positioning plate 3 is driven to rise and fall through the screw structure, and the spacing between the first positioning plate 3 and the second positioning plate 4 is adjusted. When the first positioning plate 3 is raised, the angle between the steel bar 6 of the pile head 1 and the ground increases. When the first positioning plate 3 is lowered, the angle between the steel bar 6 of the pile head 1 and the ground decreases. Of course, the actual positioning height of the first positioning plate 3 can be flexibly adjusted according to actual conditions.

[0019] like Figure 2 As shown, in the embodiment of the utility model, the guide groove is V-shaped, and a group of rotating columns 301 are rotatably installed on both sides of the inner wall. The V-shaped angle formed by the two groups of rotating columns 301 rolls against the surface of the pile head 1 steel bar 6, and reduces the friction damping between the pile head 1 steel bar 6 and the guide groove, further reducing the difficulty of bending the pile head 1 steel bar 6 under force.

[0020] like Figure 3 As shown, in the embodiment of the utility model, the guide link 5015 includes a guide rod and a guide sleeve 502. The near ends of the guide rod and the guide sleeve 502 are slidably connected, and the far ends are respectively fixedly connected to the second positioning plate 4 and the first positioning plate 3. When the first positioning plate 3 is lifted or moved, it is guided to slide by the guide rod and the guide sleeve 502, thereby improving the stability of the first positioning plate 3.

[0021] like Figure 3As shown, in the embodiment of the utility model, the screw structure includes two groups of adjusting screws 503 and fixed cylinders 504. The two groups of adjusting screws 503 are rotatably mounted on the bottom of the first positioning plate 3 and driven to rotate synchronously by the power assembly on the first positioning plate 3. The two groups of fixed cylinders 504 are fixedly mounted on the upper end of the second positioning plate 4, and a transmission nut 505 is fixed on the upper open end thereof. The transmission nut 505 and the corresponding adjusting screw 503 form a spiral pair transmission;

[0022] Furthermore, the power assembly includes a power motor 7 and a transmission belt 8. The power motor 7 is fixedly mounted on the first positioning plate 3, and its power shaft is connected to the top of a group of adjusting screws 503 through a coupling. The transmission belt 8 is used to transmit and connect the two groups of adjusting screws 503. A transmission wheel 9 for connecting the transmission belt 8 is coaxially mounted on the adjusting screw 503. When the first positioning plate 3 is driven to rise and fall, the power motor 7 drives one group of adjusting screws 503 to rotate, and cooperates with the transmission belt 8 and the transmission wheel 9 to drive another group of adjusting screws 503 to rotate. The two groups of adjusting screws 503 are threadedly driven with the corresponding transmission nuts 505 to achieve the adjustment of the spacing between the first positioning plate 3 and the second positioning plate 4.

[0023] At the same time, in the present invention, since the guide sleeve 502 and the fixed cylinder 504 are both fixedly mounted on the second positioning plate 4, multiple groups of the guide sleeve 502 and the fixed cylinder 504 are fixedly connected by reinforcing rods 506 to improve the stability of the guide sleeve 502 and the fixed cylinder 504.

[0024] To sum up the above, the utility model designs a first positioning plate 3 and a second positioning plate 4 coaxially arranged from top to bottom in the vertical direction, and arranges the first positioning plate 3 with a large radial specification on the upper side of the second positioning plate 4, and according to the bending condition of the steel bars 6 of the pile head 1, the first positioning plate 3 is driven to rise and fall through the screw structure, and the spacing between the first positioning plate 3 and the second positioning plate 4 is adjusted accordingly, thereby solving the problem that when breaking the bending adjustment of the pile head 1, manual mechanical prying or hot bending is often performed, which is labor-intensive and time-consuming, has high labor intensity and high construction risk.
