Description

Technical Field

[0001] This utility model relates to the field of hoisting tooling technology, and in particular to a hoisting tool and hoisting assembly. Background Technology

[0002] In the design process of some shaft parts, the design scheme of structural optimization is usually followed. The cost-optimal solution is often sought in the design of the product itself, rather than making too many design considerations in the production and transportation process. Therefore, it brings a lot of inconvenience to the hoisting and handling of the product.

[0003] Most lifting tools in related technologies employ traditional threaded tightening structures, requiring threaded holes to be drilled at appropriate locations on shaft parts. The production and machining of these threaded holes increases manufacturing costs. Furthermore, lifting solutions using threaded holes require tightening the threads during installation, resulting in low installation efficiency and impacting production cycle time.

[0004] Therefore, there is an urgent need for a new type of hoisting tool and hoisting components. Utility Model Content

[0005] The purpose of this utility model is to provide a lifting tool and lifting assembly. The lifting tool has multiple split-type clamps that can cooperate with each other to form a receiving chamber during clamping. The limiting section inside the receiving chamber engages with the workpiece to complete the clamping of the workpiece. It does not require additional processing of the workpiece, thus reducing manufacturing costs. At the same time, the reasonable structural design can avoid lifting failure and workpiece falling caused by misalignment.

[0006] This utility model embodiment discloses a lifting tool for lifting workpieces, including multiple clamps;

[0007] Each of the multiple clips has a circumferential sidewall, and at least one of the circumferential sidewalls has a circumferentially extending limiting segment on its inner surface.

[0008] When in a clamping state, multiple clamps are connected in sequence so that multiple circumferential sidewalls enclose and form a receiving cavity for accommodating the workpiece. The receiving cavity has an opening on at least one side, and the limiting segment is located inside the receiving cavity for clamping the workpiece.

[0009] Furthermore, there are two clamps, and the cross-sections of the two circumferential sidewalls are both semi-circular arcs. When in the clamping condition, the two clamps cooperate with each other so that the circumferential sidewalls enclose and form the receiving cavity with a circular cross-section.

[0010] Furthermore, the limiting segment is located at the opening position, and the cross-section of the limiting segment on the radial plane is arc-shaped, square, or irregular.

[0011] Furthermore, each of the plurality of clamps also has a shoulder arranged along the end face of the circumferential sidewall, and the lifting tool further includes a safety sleeve, wherein, when in the clamping condition, the safety sleeve is sleeved on the plurality of circumferential sidewalls and abuts against the shoulder.

[0012] Furthermore, the safety sleeve is a hollow cylindrical structure, and the inner wall surface of the safety sleeve has a ring-shaped abutment section. When in the clamping condition, the inner wall surface is in contact with the circumferential side wall, and the abutment section abuts against the shoulder.

[0013] Furthermore, the multiple clips are all identical in shape, so that when in the clamping state, the multiple shoulders are flush with each other and simultaneously abut against the abutting section.

[0014] Further, the corner segment of the shoulder is arc-shaped and transitions away from the circumferential sidewall. When in clamping condition, the multiple corner segments of the multiple shoulders cooperate with each other so that a accommodating gap can be formed at the cooperation point.

[0015] Furthermore, the hoisting tool also includes a fixing unit, and when in the clamping condition, multiple clamps are connected in sequence through the fixing unit.

[0016] Furthermore, the fixing unit includes mating magnets, and there are multiple mating magnets, with each of the multiple mating magnets corresponding to and compatible with one of the multiple clips.

[0017] Furthermore, the clip also has a mating plate extending along the axial direction, the mating plate being connected to the circumferential sidewall, and a receiving groove being provided in the mating plate, in which the mating magnet is embedded.

[0018] Furthermore, the mating plate is also provided with a lifting through hole.

[0019] This utility model embodiment further discloses a hoisting assembly, which includes the above-described hoisting tools.

[0020] The hoisting tool and hoisting components provided by this utility model have at least the following beneficial effects, including but not limited to:

[0021] 1) This lifting tool has multiple split-type clamps. In the clamping condition, the multiple clamps can cooperate with each other to form a receiving chamber. The limiting section in the receiving chamber engages with the workpiece to complete the clamping of the workpiece. It does not require additional processing of the workpiece, which reduces manufacturing costs. At the same time, the reasonable structural design can avoid lifting failure and workpiece falling caused by misalignment.

[0022] 2) The limiting section in this lifting tool can be arc-shaped, square, or irregularly shaped to adapt to shaft workpieces of different shapes, thus improving the versatility of the lifting tool. Specifically, the arc-shaped limiting section is suitable for shaft parts with cylindrical necks, providing uniform force distribution, reducing stress concentration, and improving clamping stability; the square limiting section is suitable for shaft parts with angular or non-circular necks, improving the fit with the workpiece and enhancing the clamping force; the irregularly shaped limiting section can be customized according to the shape of a specific workpiece to meet the lifting needs of special workpieces, thus enhancing the applicability of the lifting tool.

[0023] 3) When the lifting tool is in the clamping state, the safety sleeve is fitted on the circumferential sidewalls of multiple clamps and abuts against the shoulder. The safety sleeve provides additional restraint, making the multiple clamps fit tightly together and preventing the clamps from deforming or loosening under force. This improves the load-bearing capacity of the lifting tool and makes it suitable for heavier workpieces. At the same time, the use of the safety sleeve simplifies the installation steps. Simply surround the workpiece with the clamps and then put on the safety sleeve. No additional bolts or fasteners are needed, which improves the installation and disassembly efficiency of the lifting tool. It can quickly complete the lifting preparation work and improve the production cycle.

[0024] 4) This hoisting tool uses mating magnets as fixing units. The mating magnets can provide non-contact adsorption force, and the clamps can be quickly connected without the need for screws, bolts and other fasteners, which improves installation efficiency. In actual use, you only need to bring the clamps close together, and they can be automatically attracted and aligned by magnetic force, reducing manual alignment and fixing operations.

[0035] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.

[0036] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the illustrations only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0037] Please refer to Figures 1-4 This utility model provides a lifting tool 100 for lifting a workpiece 200. The lifting tool 100 includes a plurality of clamps 10; each of the plurality of clamps 10 has a circumferential sidewall 101, and at least one circumferential sidewall 101 has a circumferentially extending limiting section 102 on its inner surface; wherein, when in the clamping condition, the plurality of clamps 10 are connected in sequence so that the plurality of circumferential sidewalls 101 enclose a receiving cavity 103 for receiving the workpiece, the receiving cavity 103 has an opening on at least one side, and the limiting section 102 is located inside the receiving cavity 103 for clamping the workpiece 200.

[0038] It should be noted that the circumferential sidewall 101 refers to the sidewall surface surrounding the workpiece in the circumferential direction, and its cross-section can be arc-shaped. Depending on the specific implementation environment, the circumferential sidewall 101 can also have other shapes that match the shape of the workpiece, such as wavy shapes. This embodiment does not constitute a limitation on the shape of the circumferential sidewall 101, but only provides an example of its position during clamping. Meanwhile, in this embodiment, the shape of the limiting segment 102 is adapted to the shape of the workpiece's process neck, thus enabling it to be used for clamping the workpiece.

[0039] It should also be noted that clamping conditions refer to conditions such as... Figure 1 In the state shown, multiple clamps 10 are mutually enclosed to form a receiving chamber 103. Under normal operating conditions, the various components of the lifting tool 100 can be separated, and the specific structure can be as follows: Figure 3 As shown.

[0040] It should also be noted that the workpiece in this embodiment refers to a cylindrical shaft-like part with a process neck (such as...). Figure 4 As shown, the process neck is not machined to fit the lifting tool 100, but rather it requires a process neck to meet its functional and layout requirements.

[0041] It is worth noting that the lifting tool 100 has multiple separate clamps 10. During clamping, the multiple clamps 10 can cooperate to form a receiving chamber 103. The limiting section 102 within the receiving chamber 103 engages with the workpiece to complete the clamping of the workpiece. This eliminates the need for additional workpiece processing, reducing manufacturing costs. Furthermore, the reasonable structural design can prevent lifting failures and workpiece falls caused by misalignment. It is understood that at least one circumferential sidewall 101 has a circumferentially extending limiting section 102 on its inner surface. This means that the inner surface of each circumferential sidewall 101 can have a limiting section 102, or only a single circumferential sidewall 101 can have a limiting section 102. In specific application scenarios, different types of clamps 10 can be determined according to the specific shape of the workpiece.

[0042] Please refer to this again. Figure 1 and Figure 2 There are two clips 10. The cross-section of the two circumferential sidewalls 101 is semi-circular. When in the clamping condition, the two clips 10 cooperate with each other so that the circumferential sidewalls 101 enclose and form a accommodating chamber 103 with a circular cross-section.

[0043] It is worth noting that the design of two clamps 10 is simpler and more practical, requiring only a few mating surfaces to complete the closure, making the installation process quick. However, if three or four clamps 10 are used, multiple mating surfaces are needed, requiring alignment and fixing one by one during assembly, increasing installation steps and reducing operational efficiency. Meanwhile, the semi-circular circumferential sidewall 101 is adapted to shaft-type workpieces, facilitating industrial application and eliminating the need to redesign the workpiece to be clamped. Depending on the specific implementation environment, other numbers of clamps 10, such as three or four, can also be used to enclose and form the accommodating chamber 103, making it easier for the lifting tool 100 to accommodate shaft-type workpieces of specific shapes. This embodiment does not constitute a limitation on the number of clamps 10, but is merely an illustrative example.

[0044] Please refer to this again. Figure 2 The limiting segment 102 is located in the open position, and the cross-section of the limiting segment 102 in the radial plane is arc-shaped, square, or irregular. It can be understood that the cross-section in the radial plane refers to... Figure 2 The cross-section shown.

[0045] It is worth noting that the limiting section 102 in the lifting tool 100 can be arc-shaped, square, or irregularly shaped to adapt to shaft workpieces of different shapes, thereby improving the versatility of the lifting tool 100. Specifically, the arc-shaped limiting section 102 is suitable for shaft parts with arc-shaped grooves in the process neck, which can provide uniform force distribution, reduce stress concentration, and improve clamping stability; the square limiting section 102 is suitable for shaft parts with sharp edges or non-perfect circles in the process neck, in order to improve the fit with the workpiece and enhance the clamping force; the irregularly shaped limiting section 102 can be customized according to the shape of a specific workpiece to meet the lifting requirements of special workpieces and enhance the applicability of the lifting tool 100.

[0046] In some embodiments, each of the plurality of clamps 10 further has a shoulder 104 arranged along the end face of the circumferential sidewall 101, and the lifting tool 100 further includes a safety sleeve 11, wherein, when in the clamping condition, the safety sleeve 11 is sleeved on the plurality of circumferential sidewalls 101 and abuts against the shoulder 104.

[0047] It is worth noting that when the lifting tool 100 is in the clamping state, the safety sleeve 11 is fitted onto the circumferential sidewalls 101 of the multiple clamps 10 and abuts against the shoulder 104. The safety sleeve 11 provides additional restraint, ensuring that the multiple clamps 10 fit tightly together, preventing deformation or loosening of the clamps 10 under force, and improving the load-bearing capacity of the lifting tool 100. This makes it suitable for heavier workpieces. At the same time, the use of the safety sleeve 11 simplifies the installation process. Simply surround the workpiece with the clamps 10 and then put on the safety sleeve 11. No additional bolts or fasteners are needed, which improves the installation and disassembly efficiency of the lifting tool 100. It can quickly complete the lifting preparation work and improve the production cycle.

[0048] Optionally, the safety sleeve 11 is a hollow cylindrical structure, and the inner wall surface of the safety sleeve 11 has a ring-shaped abutment section 111. When in the clamping condition, the inner wall surface is in contact with the circumferential side wall 101, and the abutment section 111 abuts against the shoulder 104.

[0049] Specifically, the annular support section 111 forms a 360° circumferential fixation, ensuring structural stability after engaging with the shoulder 104, so as to ensure that the clip 10 will not loosen due to vibration or external impact when under force. Compared with single-point or local fixation, the annular structure can evenly distribute the force and improve the overall stability.

[0050] In some embodiments, the multiple clips 10 are identical in shape so that when in the clamping condition, the multiple shoulders 104 are flush with each other and simultaneously abut against the abutment section 111.

[0051] It is worth noting that this structure forms a forced alignment mechanism to ensure that each clip 10 is in the correct position, improves the overall assembly accuracy, and prevents the safety sleeve 11 from being installed even if the clip 10 is not fully clamped (misaligned), thereby avoiding safety hazards caused by insecure clamping.

[0052] Please refer to this again. Figure 2 The shoulder 104 is separated from the corner section of the circumferential sidewall 101 by a rounded transition. When in the clamping condition, the multiple corner sections of the multiple shoulders 104 cooperate with each other so that the cooperation point can form an accommodating gap 106.

[0053] It is worth noting that the design of the accommodating clearance provides sufficient space for shaft-type workpieces, ensuring that the workpieces will not interfere with the shoulders or circumferential sidewalls during installation, thereby ensuring that the workpieces can be smoothly loaded and unloaded, thus improving loading and unloading efficiency.

[0054] In some embodiments, the lifting tool 100 further includes a fixing unit, and when in a clamping condition, multiple clamps 10 are connected in sequence through the fixing unit.

[0055] Optionally, the fixing unit may include mating magnets 12, and there may be multiple mating magnets 12, with each of the multiple mating magnets 12 corresponding to and being compatible with multiple clips 10.

[0056] Specifically, the hoisting tool 100 uses mating magnets 12 as fixing units. The mating magnets 12 can provide non-contact adsorption force, and the clamps 10 can be quickly connected without screws, bolts or other fasteners, which improves installation efficiency. In actual use, the clamps 10 only need to be brought close together, and they can be automatically adsorbed and aligned by magnetic force, reducing manual alignment and fixing operations.

[0057] It should be noted that the fixing unit can also be a snap-fit ​​structure, which completes the relative positioning of multiple clips 10 by snapping them together. This embodiment does not constitute a limitation on the specific structural type of the fixing unit.

[0058] Optionally, the clip 10 also has a mating plate 105 that extends along the axial direction. The mating plate 105 is connected to the circumferential sidewall 101, and a receiving groove 1051 is provided in the mating plate 105, in which the mating magnet 12 is embedded.

[0059] Specifically, the receiving groove 1051 within the mating plate 105, where the magnet 12 is embedded, effectively protects the magnet, preventing it from falling off or being damaged due to external impact during use, thus improving durability. The connection between the mating plate 105 and the circumferential sidewall 101 forms an integrated design, which enhances the overall structural strength, reduces stress concentration, and improves resistance to deformation. In this embodiment, the axial direction refers to the axial direction of the workpiece, or it can be understood as the axial direction of the clamp 10, such as... Figure 2 The diagram shows the direction from top to bottom (or bottom to top).

[0060] In some embodiments, the mating plate 105 also has a lifting through hole 1052. It is understood that the design of the lifting through hole 1052 provides a dedicated lifting connection point, allowing the lifting tool 100 to be easily connected to other lifting equipment (such as hooks, slings, etc.) in other lifting assemblies. This structural arrangement simplifies the coordination of tools during lifting, eliminating the need for additional adapters or complex connection methods, and improving the convenience and efficiency of lifting operations.

[0061] At the same time, such as Figure 3 It can be seen that the lifting through hole 1052 is located in the middle of the mating plate 105, which can ensure that the stress point of the lifting equipment is in a reasonable position and avoid deformation or loosening of the lifting tool 100 due to uneven stress.

[0062] This utility model embodiment further discloses a hoisting assembly, which includes the hoisting tool 100 described above and has all its beneficial effects.
