[0031] In related technologies, eco-frames are precast concrete products that require stacking in a stepped manner during installation. Due to their large size, installation necessitates the use of truck cranes. The lifting equipment used directly impacts the quality, construction speed, and on-site safety of the eco-frame installation. Therefore, how to improve the construction speed of eco-frame hoisting while ensuring construction safety is a technical problem that urgently needs to be solved by those skilled in the art.

[0032] To address the problems existing in the aforementioned related technologies, this utility model provides an eco-frame lifting tool 10. At least three lifting claws 40 are provided at the end of the main shaft tube 30. Each lifting claw 40 includes an extension 41 and a baffle 42 connected to the end of the extension 41 away from the main shaft tube 30, with the baffle 42 extending upwards. Using a crane to lift the lifting ring 20, the main shaft tube 30 or the lifting claws 40 are first tilted so that the lifting claws 40 located on one side semicircle of the main shaft tube 30 are inserted into the pre-drilled holes 12 on one side frame of the eco-frame 11. Then, the height and tilt angle of the main shaft tube 30 or the lifting claws 40 are adjusted, and the lifting claws located on the other side semicircle of the main shaft tube 30 are... The lifting claw 40 is inserted into the reserved hole 12 on the other side of the ecological frame 11. The extension 41 of the lifting claw 40 passes through the reserved hole 12 of the ecological frame 11. The baffle 42 of the lifting claw 40 is located on the side of the reserved hole 12 of the ecological frame 11 away from the center of the ecological frame 11. During the lifting of the ecological frame 11, the baffle 42 of the lifting claw 40 can effectively prevent the ecological frame 11 from slipping, ensuring the stability and safety of the lifting operation. After the ecological frame 11 is in place, by appropriately reducing the upward lifting force of the crane on the lifting ring 20, and adjusting the height and tilt angle of the main shaft tube 30 or the lifting claw 40, the lifting claw 40 can be smoothly pulled out from the reserved hole 12, thereby achieving fast and safe lifting operation and improving construction efficiency.

[0033] The following detailed description is based on specific embodiments.

[0034] Combination Figures 1 to 6 As shown, an embodiment of the present invention provides an eco-frame hoisting tool 10, which includes a lifting ring portion 20, a main shaft tube 30, and at least three lifting claws 40. The main shaft tube 30 is connected to the lifting ring portion 20. The lifting claws 40 are disposed on the outer peripheral wall of the end of the main shaft tube 30 away from the lifting ring portion 20, and are spaced apart circumferentially along the main shaft tube 30. Specifically, in the top view of the eco-frame hoisting tool 10, at least one lifting claw 40 is disposed on one side semicircle of the main shaft tube 30, and at least one lifting claw 40 is disposed on the other side semicircle of the main shaft tube 30. The lifting claw 40 includes an extension portion 41 and a baffle 42. The extension portion 41 extends from the outer side wall of the main shaft tube 30 in a direction away from the main shaft tube 30, and the baffle 42 is connected to the end of the extension portion 41 away from the main shaft tube 30, and the baffle 42 extends upward.

[0035] It is understandable that the ecological frame 11 has a frame structure, consisting of a border (such as a rectangular or polygonal border) and an internal support structure. The whole has a certain degree of openness. The reserved holes 12 are set on the border of the ecological frame 11 and are located on opposite sides of the ecological frame 11. The main shaft tube 30 is roughly aligned with the center of the frame. The lifting claw 40 is inserted into the reserved hole 12 of the border from inside the frame and extends out of the border. The inner diameter of the reserved hole 12 needs to allow the extension 41 of the lifting claw 40 and the baffle 42 to pass through.

[0036] For details, please refer to [link / reference]. Figures 1 to 3The lifting claws 40 do not need to be concentrated on one side of the semicircle of the main shaft tube 30. At least one claw should be arranged on each of the two semicircles. Since the eco-frame 11 itself has a certain weight, if all the lifting claws 40 are concentrated on one side of the main shaft tube 30 during lifting, it will cause a shift in the center of gravity, potentially leading to lifting tilt, uneven force on the tool, or even the eco-frame 11 falling off, thus affecting lifting safety. From the top view of the eco-frame lifting tool 10, at least one of the lifting claws 40 is positioned on one side of the semicircle of the main shaft tube 30. The main shaft tube 30 is placed on the other semicircle of the main shaft tube 30. First, the main shaft tube 30 or the lifting claw 40 is tilted so that the lifting claw 40, which is set on one semicircle of the main shaft tube 30, is inserted into the reserved hole 12 on one side of the ecological frame 11. Then, the height and tilt angle of the main shaft tube 30 or the lifting claw 40 are adjusted, and the lifting claw 40, which is set on the other semicircle of the main shaft tube 30, is inserted into the reserved hole 12 on the other side of the ecological frame 11. This ensures that the ecological frame 11 is subjected to balanced force during hoisting, prevents tilting or shaking, and improves hoisting stability. The length of the extension 41 of the lifting claw 40 can be set according to the size of the ecological frame 11 to ensure that the lifting claw 40 can be firmly inserted into the reserved hole 12. At the same time, the design of the baffle 42 can effectively block the lateral displacement of the ecological frame 11 during hoisting, forming a physical limit. When the ecological frame 11 shakes, the baffle 42 can directly abut against the outer wall of the ecological frame 11 to prevent the ecological frame 11 from falling off the end of the lifting claw 40, further enhancing the stability and safety of hoisting. After the ecological frame 11 is in place, by appropriately reducing the upward lifting force of the crane on the lifting ring 20, and adjusting the height and tilt angle of the main shaft tube 30 or the lifting claw 40, the lifting claw 40 can be smoothly pulled out from the reserved hole 12, thereby achieving rapid and safe hoisting operations and improving construction efficiency.

[0037] The number of lifting claws 40 is at least three, which can basically ensure the stability of the lifting. For ease of description, this article uses four lifting claws 40 as an example for description and illustration.

[0038] In some embodiments, please refer to the following for details. Figure 2 , Figure 3 The extension 41 includes a first part 43 and a second part 44; wherein the first part 43 extends downward from the main shaft tube 30 and in a horizontal direction away from the center of the main shaft tube 30, and the second part 44 extends in a horizontal direction away from the center of the main shaft tube 30, and one end of the second part 44 away from the first part 43 is connected to the baffle 42.

[0039] The first part 43, which extends downwards, facilitates the insertion of the lifting claw 40 into the reserved hole 12 of the ecological frame 11, reducing interference between the lifting claw 40 and the frame of the ecological frame 11. The second part 44, which extends horizontally, passes through the reserved hole 12 of the ecological frame 11. During hoisting, the second part 44 abuts against the upper inner wall of the reserved hole 12 of the ecological frame 11. During hoisting, the tension is converted into a stable lifting force on the ecological frame 11 through the second part 44 of the horizontal section, reducing the swaying of the ecological frame.

[0040] Specifically, the first part 43 is welded to the main shaft tube 30 to ensure a robust structure; the second part 44 is slightly longer than the depth of the reserved hole 12.

[0041] In some embodiments, please refer to the following for details. Figure 4 The main shaft tube 30 includes a main shaft portion 31 and a rotating sleeve portion 32. The rotating sleeve portion 32 is sleeved on the outer peripheral wall of the end of the main shaft portion 31 away from the lifting ring portion 20. The rotating sleeve portion 32 is used to rotate around the main shaft portion 31 in the circumferential direction. The extension portion 41 is connected to the outer peripheral wall of the rotating sleeve portion 32.

[0042] Specifically, the rotating sleeve portion 32 can be rotatably sleeved on the outer peripheral wall of the main shaft portion 31 by means of, for example, a bearing structure.

[0043] When lifting the ecological frame hoisting tool 10, due to factors such as the crane's position, the hoisting tool may not be perfectly aligned with the pre-drilled hole 12 of the ecological frame 11. Rotating the sleeve part 32 can drive the lifting claw 40 to rotate circumferentially around the main shaft part 31. The operator can adjust the circumferential angle of the lifting claw 40 according to the actual position of the pre-drilled hole 12 of the ecological frame 11, so that each lifting claw 40 can accurately correspond to the force point of the pre-drilled hole 12 of the ecological frame 11, avoiding uneven force due to misalignment between the position of the lifting claw 40 and the pre-drilled hole 12. There is no need to move the entire hoisting tool significantly; the direction of the lifting claw 40 can be adjusted simply by rotation. Even if the ecological frame 11 is slightly tilted, the angle can be adapted by rotating the lifting claw 40, reducing the time spent adjusting the position of the ecological frame 11 and the hoisting tool, and improving construction efficiency.

[0044] In some embodiments, please refer to the following for details. Figure 5 The rotating sleeve portion 32 includes a plurality of independently rotating sub-sleeves 33, which are arranged along the axial direction of the main shaft portion 31; wherein at least one of the lifting claws 40 is connected to one of the rotating sub-sleeves 33.

[0045] If only one rotating sleeve 32 drives all the lifting claws 40 to rotate, the lifting claws 40 can only rotate at the same axial height, which cannot adapt to the pre-drilled holes 12 at different heights. The lifting claws 40 are connected to the rotating sub-sleeves 33 at the corresponding heights. The circumferential angle can be adjusted by rotating the rotating sub-sleeves 33, and the pre-drilled holes 12 can be precisely aligned at their respective axial heights, realizing the axial layer height alignment and circumferential angle adaptation of the rotating sleeve 32. Each rotating sub-sleeve 33 can rotate independently. The operator can first adjust the angle of the lifting claws 40 of the rotating sub-sleeve 33 near the bottom of the ecological frame lifting tool 10 to align with the bottom pre-drilled hole 12; then adjust the angle of the lifting claws 40 of the rotating sub-sleeve 33 near the middle of the ecological frame lifting tool 10 to align with the middle lifting point, and so on, adjusting the angle of the lifting claws 40 of the top rotating sub-sleeve 33 in sequence to ensure precise alignment of each lifting point. This ensures that the ecological frame can be in a horizontal state after being lifted, which facilitates the installation of each layer of the ecological frame and improves the efficiency of the alignment and adjustment.

[0046] In some embodiments, please refer to the following for details. Figures 4 to 6 The main shaft tube 30 also includes a head plate 34 disposed on one end of the rotating sleeve section 32 away from the lifting ring section 20. The head plate 34 is used to seal the rotating sleeve section 32, preventing internal components from leaking out and enhancing structural stability. The head plate 34 also prevents foreign objects from entering the rotating sleeve section 32 during hoisting, further ensuring the safety and reliability of the hoisting tools.

[0047] In some embodiments, please refer to the following for details. Figure 2 The plurality of lifting claws 40 include a first lifting claw 45 and a second lifting claw 46. The vertical distance between the second portion 44 of the first lifting claw 45 and the end face of the main shaft tube 30 away from the lifting ring portion 20 is a first distance H1. The vertical distance between the second portion 44 of the second lifting claw 46 and the end face of the main shaft tube 30 away from the lifting ring portion 20 is a second distance H2. The first distance H1 and the second distance H2 are different.

[0048] Due to the structural design of the eco-frame 11, such as multi-layered, stepped, or concave-convex shapes, there may be a height difference between the reserved holes 12 on the two side frames. By setting lifting claws 40 of different heights, they can correspond to the reserved holes 12 of different heights respectively, ensuring that each lifting claw 40 can be accurately matched and ensuring that the eco-frame 11 is kept horizontal when hoisted.

[0049] In some embodiments, please refer to the following for details. Figure 1 , Figure 2 , Figures 4 to 6The upper surface of the extension 41 near the baffle 42 is provided with a first anti-slip pattern 47. The second part 44 of the extension 41 is a horizontal extension section, which is the main part in contact with the ecological frame 11. Its end near the baffle 42, i.e., the bearing contact surface of the lifting claw 40 that supports the ecological frame 11, directly contacts the inner wall of the reserved hole 12 of the ecological frame 11. The ecological frame 11 is mostly made of relatively smooth materials such as concrete and stone. Increasing the friction between the lifting claw 40 and the ecological frame 11 further reduces the risk of the ecological frame 11 sliding off the lifting claw 40 during the lifting process.

[0050] Specifically, the first anti-slip pattern 47 may include multiple first protrusions, the extension direction of which is perpendicular to the extension direction of the second part 44, resembling saw teeth. The protrusions may be circular or rectangular in shape, and are evenly distributed to enhance the anti-slip effect. Optionally, the first anti-slip pattern 47 may be set in a region of 100mm to 200mm from the end of the first part 44 near the baffle 42. The specific location can be adjusted according to the depth of the pre-drilled hole, and is not specifically limited here.

[0051] In some embodiments, please refer to the following for details. Figure 1 , Figure 2 , Figure 4 , Figure 5 The surface of the baffle 42 near the main shaft tube 30 is provided with a second anti-slip pattern 48. The second anti-slip pattern 48 can effectively increase the friction between the baffle 42 and the main shaft tube 30, reduce the sliding of the ecological frame 11 relative to the baffle 42 during hoisting, and further reduce the risk of the ecological frame 11 slipping off the end of the lifting claw 40.

[0052] Specifically, the second anti-slip pattern 48 is composed of multiple second protrusions, which have various shapes and can extend vertically upwards.

[0053] In some embodiments, please refer to the following for details. Figure 6 The baffle 42 has a buffer pad 49 on the side near the main shaft tube 30. The buffer pad 49 is made of soft material and can effectively absorb the impact force during hoisting, reducing damage to the ecological frame 11. Its surface may also have an anti-slip texture to further increase friction and ensure hoisting stability.

[0054] In some embodiments, please refer to the following for details. Figures 1 to 6The lifting ring portion 20 includes a lifting ring 21 and a connecting steel plate 22. The orthographic projection of the main shaft tube 30 onto the connecting steel plate 22 is located within the connecting steel plate 22. The lifting ring 21 is connected to the main shaft tube 30 via the connecting steel plate 22. The connecting steel plate 22 has a planar structure. The connection between the main shaft tube 30 and the steel plate can be fixed by welding, bolting, or other methods. Similarly, the connection between the lifting ring 21 and the steel plate can also be stably fixed by welding or bolting. In this case, the tensile force borne by the lifting ring 21 is first transmitted to the entire connecting steel plate 22, and then evenly transmitted through the steel plate to the end of the main shaft tube 30, rather than to a localized point, significantly reducing the risk of stress concentration.

[0055] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
