This design can improve the stability of the device during use.

[0029] 2. Pull the pay-off drum to drive the movable plate to move inside the movable slot. Then observe the distance the pay-off drum moves through the scale line.

[0038] The following is combined with Figure 1-6 This application is described in further detail.

[0039] The embodiment of the present application discloses a positioning device for laying out a line for pile construction. Figure 1 and Figure 3 A laying-out and positioning device for pile foundation construction includes a supporting structure 1, a laying-out structure 3 is provided on the supporting structure 1, and the laying-out structure 3 is connected to the supporting structure 1 through a folding structure 2 to realize the folding of the laying-out structure 3.

[0040] Reference Figure 2 The support structure 1 includes a support rod 11, with a handle 12 at the upper end. The handle 12 is bolted to the outer peripheral wall of the support rod 11. A breaker cone 18 is bolted to the lower end of the support rod 11. The lower end of the breaker cone 18 is tapered. This concentrates pressure on the soil, and the lower end of the breaker cone 18 has a smaller contact area with the soil. This allows for a relatively small amount of force to generate a high pressure, making it easier to penetrate the soil and cut into it more easily.

[0041] A pedal 14 is located above the groundbreaking cone 18. Pedal 14 is bolted to the outer wall of the support rod 11, and its upper surface is provided with anti-slip grooves. Three sets of support legs 15 are also located on the outer wall of the support rod 11. These legs are positioned below pedal 14. The top ends of the legs 15 are hinged to the outer wall of the support rod 11, and the bottom ends of the legs 15 are bolted to support pads 17. A hinged rod 16 is also located midway along the length of the legs 15. One end of the hinged rod 16 is hinged to the outer wall of the leg 15, and the other end is hinged to the outer wall of the support rod 11.

[0042] When using the equipment, the operator can pick up the equipment through the handle 12, and the line-laying structure 3 is now against the support rod 11. The handle 12 controls the support rod 11 so that the earth-breaking cone 18 is aligned with the position where it needs to be installed, and the tip of the earth-breaking cone 18 is inserted into the ground. At this time, the three groups of support pads 17 begin to contact the ground. The operator steps on the pedal 14 and pushes the equipment downward with the power of the foot to insert the earth-breaking cone 18 into the soil. The three groups of support pads 17 can fit the ground. Since the contact area between the lower surface of the three groups of support pads 17 and the ground is large, they can provide better support and anti-slip performance. And through the arrangement of the three groups of support legs 15 and the hinged rod 16, the three groups of support legs 15 and the hinged rod 16 can be folded after the equipment is used, thereby reducing the overall size of the equipment and making the equipment more convenient to store.

[0043] The setting of the pedal 14 allows the user to reduce hand fatigue and make the entire soil-breaking process more efficient and labor-saving. The setting of the anti-slip pattern can increase the friction between the upper surface of the pedal 14 and the user's feet, thereby improving stability during use.

[0044] Reference Figure 2 and Figure 4Two sets of retaining rings 13 are also mounted on the outer peripheral wall of the middle portion of the support rod 11 to secure the folding structure 2. The folding structure 2 includes a fixing seat 21, which is sleeved on the outer surface of the support rod 11 and sandwiched between the two sets of retaining rings 13. The inner peripheral wall of the fixing seat 21 slides with the outer peripheral wall of the support rod 11.

[0045] The surfaces of the upper and lower ends of the fixing seat 21 are respectively fitted with the surfaces on the opposite side of the two sets of limiting rings 13, so that the position of the fixing seat 21 on the outer surface of the support rod 11 can be fixed to prevent the folding structure 2 from moving during use. Through the setting of the fixing seat 21, the folding structure 2 and the wire-releasing structure 3 can be rotated with the support rod 11 as the center to adjust the position of the wire-releasing structure 3.

[0046] Reference Figure 3 and Figure 4 A connecting plate 22 is mounted on the fixing base 21. The sidewalls of the connecting plate 22 abut against the outer peripheral wall of the fixing base 21 and are fixedly connected via bolts. A pulling plate 23 is inserted between the two opposing wings of the connecting plate 22. The pulling plate 23 is hingedly connected to hinge plates 24 at both ends of its length. The other ends of the hinge plates 24 are hingedly connected to engaging posts 25, which are inserted between the two wings of the connecting plate 22. Tension springs 26 are sleeved on both ends of the engaging posts 25 in the lengthwise direction. One end of the tension spring 26 is fixedly connected to the surface of one side of the connecting plate 22.

[0047] Two engaging plates 27 are mounted between the two opposing wings of the connecting plate 22. These engaging plates 27 are hingedly connected to the bottom of the connecting plate 22. A fixing plate 28 is fixedly connected to the bottoms of the two engaging plates 27. The engaging plates 27 are internally provided with two sets of fixing slots, each sized to match the size of the engaging posts 25.

[0048] The pulling plate 23 can move inside one end of the connecting plate 22, and the pulling plate 23 can pull the hinge plate 24 to move when moving, and at the same time drive the locking column 25 to move inside the middle position of the connecting plate 22, and can pull the tension spring 26 to retract, and the locking column 25 can be separated from the inside of the limit groove when moving. The angle between the two sets of limit grooves is ninety degrees, so that after the fixed plate 28 and the locking plate 27 are rotated ninety degrees, after releasing the pulling plate 23, the tension spring 26 can pull the hinge plate 24 and the locking column 25 to reset by its own elastic force, so that the locking column 25 is locked in the inside of another set of limit grooves. This design allows the device to fold the wire-releasing structure 3 through the folding structure 2, making the device more convenient to store and carry.

[0049] Reference Figure 3 and Figure 4The pay-off structure 3 includes an adjustment plate 31. One end of the adjustment plate 31 in the longitudinal direction is connected to the fixed plate 28 by bolts, and the top wall of the adjustment plate 31 is in contact with the bottom wall of the fixed plate 28. A scale line 32 is provided on the side wall of the adjustment plate 31.

[0050] Reference Figure 4 and Figure 5 A movable groove is provided on the top wall of the adjusting plate 31 along the thickness direction, and the length direction of the movable groove is parallel to the length direction of the adjusting plate 31. A wire-paying drum 33 is movably provided on the adjusting plate 31, and the wire-paying drum 33 is inserted into the movable groove. A movable plate 34 is installed at the bottom end of the wire-paying drum 33, and the movable plate 34 is inserted into the inside of the movable groove provided on one side surface of the adjusting plate 31. An external thread is provided on the outer wall of the bottom end of the wire-paying drum 33, and the outer surface of the lower end of the wire-paying drum 33 is threadedly connected to a tightening nut 35, and the upper surface of the tightening nut 35 is in contact with the lower surface of the adjusting plate 31. A connecting seat 36 is fixedly connected to one end of the adjusting plate 31 away from the fixed plate 28.

[0051] Reference Figure 5 and Figure 6 A support plate 37 is fixedly connected to the outer surface of one side of the connecting seat 36. A limit block 38 is inserted into the interior of the support plate 37 and the connecting seat 36, and the surface of one end of the limit block 38 is in contact with the surface of one end of the adjustment plate 31. A spring 39 is sleeved on the outer surface of the upper end of the limit block 38, and the upper and lower ends of the spring 39 respectively abut against the surface of the end opposite to the support plate 37 and the connecting seat 36.

[0052] Pulling the payoff drum 33 causes the movable plate 34 and the abutting nut 35 to move synchronously. As the movable plate 34 moves, the distance traveled by the payoff drum 33 can be observed through the scale lines 32, thereby determining the payoff radius of the device. Rotating the abutting nut 35 causes its upper surface to abut against the lower surface of the adjustment plate 31, thereby fixing the position of the payoff drum 33.

[0053] When the wire-releasing structure 3 needs to be folded, pull the limit block 38 so that the limit block 38 moves inside the connecting seat 36 and the support plate 37, and the spring 39 can be pressed to shrink so that one end of the limit block 38 is separated from the surface of one end of the adjustment plate 31. At this time, the wire-releasing drum 33, the movable plate 34 and the tightening nut 35 can be removed from the inside of the adjustment plate 31.

[0054] The implementation principle of the line-laying and positioning device for pile foundation construction according to the embodiment of the present application is as follows: first, the device is picked up by the handle 12, and the soil-breaking cone 18 is placed on the ground. Then, the device is inserted into the soil through the pedal 14. Then, the device is supported between the ground and the three sets of support legs 15, the hinged rod 16 and the support pad 17, thereby fixing the position of the device. Then, the line-laying drum 33 is pulled to move inside the adjustment plate 31, and the position of the line-laying drum 33 is determined by the scale line 32 and the movable plate 34, thereby determining the radius size of the line-laying. Then, the nut 35 is rotated to tighten against the lower surface of the adjustment plate 31, thereby fixing the position of the line-laying drum 33. Then, white lime is added to the inside of the line-laying drum 33. Then, the line-laying structure 3 is rotated to lay the line with the support rod 11 as the center of the circle.

[0055] After the line is released, the limit block 38 is pulled to disengage the limit block 38 from one end of the adjustment plate 31. Then the line-releasing spool 33, the movable plate 34, and the tightening nut 35 can be taken out from the inside of the adjustment plate 31. Then the pulling plate 23 is pulled to drive the hinged plate 24 and the engaging column 25 to move, and the tension spring 26 is pulled to expand and contract, so that the engaging column 25 is disengaged from the inside of a set of limiting grooves. Then the line-releasing structure 3 is rotated ninety degrees to drive the fixed plate 28 and the engaging plate 27 to rotate synchronously. After that, after releasing the pulling plate 23, the tension spring 26 can pull back the hinged plate 24 and the engaging column 25 by its own elastic force, so that the engaging column 25 is engaged with another set of limiting grooves. At this time, the device is in a folded state.

[0056] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
