[0002] In the aluminum profile processing industry, the handling and hoisting of square tubes are common processes. Traditional lifting tools mostly use fixed structures or direct rope binding methods, which have the following limitations: poor adaptability; fixed lifting tools can only match profiles of a single size or quantity, requiring frequent tool changes when lifting profiles of different sizes and quantities, which is inconvenient; rope binding relies on manual operation, which is inefficient and prone to tilting and slippage due to uneven binding; secondly, the edges of the profile may wear down the ropes during binding, posing a risk of breakage with long-term use; and using rigid lifting tools to directly contact the inner wall of the profile can easily cause scratches, affecting surface quality; in addition, existing modular lifting tools are mostly connected by bolts, which is cumbersome to disassemble and assemble, and makes it difficult to quickly adjust the support spacing and range to adapt to the specification changes of different batches of profiles. Therefore, there is an urgent need for a lifting tool for square aluminum profile processing that is easy to adjust, easy to disassemble and assemble, and applicable to different types of square tube profiles.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0018] Reference Figure 1 , Figure 2 and Figure 3As shown, this utility model provides the following technical solution: a lifting tool for processing square aluminum profiles, including a square tube 1, the specific structure of which refers to common aluminum profiles in the prior art. First connecting plates 2 are symmetrically arranged on both sides of the square tube 1. One side of the first connecting plate 2 is connected to the collar 31 of the pulling rope 3 via a connecting ring 23. The other end of the pulling rope 3 is connected to an external lifting device. The lifting device is wound up by its winding component, thereby pulling the square tube 1 upwards. The structure, principle, and connection method of the lifting device with the pulling rope 3 can all refer to the prior art. Multiple first rectangular slots 24 are provided on the other side of the first connecting plate 2. Second connecting plates 4 are inserted laterally via first rectangular inserts 41. Different numbers of second connecting plates 4 can be inserted, and a first T-shaped connector passes through the first connecting plate 2 and the first rectangular insert 41. The first rectangular slot 24, the second rectangular slot 42, and the third rectangular slot 5 are locked by a second rectangular insert 51. The third rectangular slot 5 is inserted vertically through the second rectangular insert 51. Different numbers of third rectangular slot 5 can be inserted. The slot 5 is locked by a second T-shaped pin 44 that passes through the second connecting plate 4 and the second rectangular insert 51. The third rectangular slot 5 is also provided with multiple third rectangular slots 52. The third rectangular insert 62 is inserted into the third rectangular insert 62. Different numbers of support rods 6 can be inserted. The support rods 6 are locked by a third T-shaped pin 54 that passes through the third connecting plate 5 and the third rectangular insert 62. At least one support rod 6 is inserted into the inner side of the end of the square tube 1. The first rectangular slot 24, the second rectangular slot 42, and the third rectangular slot 52 are all distributed in multiple groups to make the number, spacing, and orientation of the support rods 6 adjustable. Specifically, using the above technical solution, when lifting the square tube 1, the two side support rods 6 are inserted into the inner sides of both ends of the square tube 1, and then the lifting equipment retracts the pulling rope 3, causing it to move the connecting plate and support rod 6 upwards. This allows the support rod 6 to be tilted and supported on the inner wall of the square tube 1, thus pulling the square tube 1 upwards. Different numbers of second connecting plates 4 can be inserted through the multiple first rectangular slots 24, different numbers of third connecting plates 5 can be inserted through the multiple second rectangular slots 42, and different numbers of support rods 6 can be inserted through the multiple third rectangular slots 52. This allows multiple square tubes 1 to be inserted and supported at one time, enabling the simultaneous lifting of multiple square tubes 1. In addition, the operator can adjust the position of the multiple rectangular rods inside different rectangular slots to adjust the spacing between adjacent connecting plates and support rods 6, thereby enabling the lifting operation for square tubes 1 of different sizes and improving the adaptability of the lifting equipment.

[0019] Reference Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, specifically, the first connecting plate 2 has a first pin hole 21, the end of the first rectangular insert 41 has a fourth pin hole 411, and the first T-shaped pin 22 passes through both the first pin hole 21 and the fourth pin hole 411 to achieve locking. The pin and the pin hole are matched in size, ensuring stable insertion. The top T-shaped structure also provides protection, preventing easy detachment. The second connecting plate 4 has a second pin hole 43, the end of the second rectangular insert 51 has a sixth pin hole 511, and the second T-shaped pin 44 passes through both the second pin hole 43 and the sixth pin hole 511 to achieve locking. The third connecting plate 5 has a fifth pin hole 53, the end of the third rectangular insert 62 has an eighth pin hole 621, and the third T-shaped pin 54 passes through both the fifth pin hole 53 and the eighth pin hole 621 to achieve locking. The pins facilitate the insertion and installation of different numbers of connecting plates and support rods 6. The fourth pin hole 41... The first connecting plate 2 has two mutually perpendicular fourth pin holes 411, which are also through the top, bottom, left, and right sides. The second connecting plate 4 has a third pin hole 45, which is perpendicular to the second pin hole 43. This is used to adjust the horizontal or vertical splicing of the second connecting plate 4, and to allow the second connecting plate 4 to be rotated to one side of the first connecting plate 2 to adjust the insertion position, thus achieving vertical or horizontal insertion. The third connecting plate 5 has two mutually perpendicular sixth pin holes 511, and the third connecting plate 5 has a seventh pin hole 55, which is perpendicular to the fifth pin hole 53. This is used to adjust the horizontal or vertical splicing of the third connecting plate 5. Similarly, the third connecting plate 5 can be adjusted to one side of the second connecting plate 4 to achieve vertical or horizontal insertion. The slots and insertion surfaces of the first connecting plate 2, the second connecting plate 4, and the third connecting plate 5 are interference fits, ensuring stable insertion and preventing shaking. Specifically, through the above technical solution, the first connecting plate 2, the second connecting plate 4, the third connecting plate 5, and the support rod 6 are all locked together by pins after being inserted into each other. Compared with the traditional bolt fixing method, this facilitates subsequent disassembly and assembly, reduces operation time by more than 50%, and if one of the components is damaged in the future, it is not necessary to discard the entire tool; only one component needs to be replaced. In addition, through the pin holes in different positions, the second connecting plate 4 and the third connecting plate 5 can be flexibly rotated to adjust their vertical or horizontal position, which facilitates the adjustment of the number of inserted support rods 6, thereby facilitating the adjustment of the number of inserted square tubes 1, and making the adjustment flexible. Example

[0020] In another embodiment of this solution, refer to Figure 2 and Figure 6 As shown, specifically, the support rod 6 includes a metal main rod 61, which is used to ensure the support strength and meet the general profile load. The third rectangular insert rod 62 is fixed to the end of the metal main rod 61. A rubber protective sleeve 63 is sleeved on the outside of the metal main rod 61 to elastically support the inner wall of the square tube 1, avoiding the situation where the coating is easily scratched or deformed by the traditional rigid structure directly abutting against the inner wall of the square tube 1. Example

[0021] In another embodiment of this solution, refer to Figure 1 , Figure 2 and Figure 3 As shown, specifically, two symmetrical pull ropes 3 are provided. The loops 31 of the two pull ropes 3 are respectively connected to the two connecting loops 23 of the first connecting plate 2. During lifting, the two pull ropes 3 pull the two ends of the first connecting plate 2 at the same time, so that the first connecting plate 2 always remains horizontal when it moves upward, which is used to maintain the lifting balance of the square tube 1. The double pull ropes 3 are symmetrically distributed and combined with the adjustable support points to effectively distribute the force and avoid the profile tilting or rotating during the lifting process.

[0022] The working principle and usage process of this utility model are as follows: When lifting the square tube 1 profile, the operator binds or connects the lifting equipment's pull rope 3 to the two connecting rings 23 of the first connecting plate 2 to ensure a stable connection. Then, according to the required number or size of the square tube 1 to be lifted, different numbers of second connecting plates 4 are inserted into one side of the first connecting plate 2, the insertion spacing is adjusted, and the plates are locked by pins passing through the rectangular inserts and rectangular slots. Similarly, different numbers of third connecting plates 5 are inserted into one side of the second connecting plate 4, the insertion spacing is adjusted, and the plates are locked by pins passing through. Finally, the operator inserts the corresponding number of support rods 6 into... The rectangular slot on the third connecting plate 5 is also locked by a pin. Then, the operator inserts the support rods 6 of the lifting structures on both sides into the inner sides of the two ends of the square tube 1, and arranges the square tubes 1 in a reasonable manner so that most of the square tubes 1 are evenly distributed. Then, the external lifting equipment pulls the traction rope 3, which pulls the support rod 6 to tilt inside the square tube 1 through the connecting plate. The tilted support rod 6 abuts against the inner wall of the square tube 1, thereby lifting the square tube 1. The connecting plate and support rod 6, which can be spliced ​​and flexibly adjusted, are convenient for lifting square tubes 1 of different quantities and sizes. At the same time, the overall tool structure is simple and easy to disassemble and assemble.

[0023] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
