[0002] Rapid hoisting tools for steel structure construction mainly include steel plate hooks, chain slings, clamp slings, and lifting suction cups.

[0003] For example, Chinese patent CN209291798U discloses a steel plate lifting hook, including a hook and a pin. The hook is an integral structure, including a left clamp and a right clamp, both of which have an open structure. A locking block is provided in the middle of the left and right clamps, with a placement plate at one end of the opening and the hook at the other end. The longitudinal section of the placement plate is trapezoidal. The locking groove of the pin is connected to the locking block. The steel plate lifting hook with the above structure makes it difficult for the steel plate to detach from the hook, thus improving the safety of lifting the steel plate.

[0004] The aforementioned patent has the following problems:

[0005] This patent has some drawbacks in its use. For example, while the aforementioned steel plate hook can clamp the steel plate, when the steel plate swings in the air, the locking pin may fail to clamp the steel plate due to the swinging motion. In severe cases, the steel plate may fall off between multiple hooks. Therefore, a rapid lifting tool for steel structure construction is proposed. Utility Model Content

A sliding rod is slidably connected in the first sliding groove, and one end of the sliding rod extends to the outside and is fixed to the rotating block. A limit block is slidably connected in the first sliding groove.

[0010] A drive assembly, located inside the rotating rod, is used to drive the limiting block to slide.

[0011] Based on the above structure, the fixed block and rotating block ensure that the rotating block rotates within the fixed block. The rotating groove and rotating rod ensure that the rotating rod rotates between the two rotating grooves. The first sliding groove and sliding rod ensure that when the locking pin rotates within the locking hook, the locking pin drives the sliding rod to slide along the first sliding groove via the fixed block and rotating block. The drive component and limiting block ensure that the user can move the limiting block via the drive component. When the sliding rod moves to the appropriate position, the user can control the limiting block to abut against the sliding rod to fix the sliding rod.

[0012] In the above technical solution, the driving component further includes:

[0013] The second slide groove is formed on one side of the first slide groove. A slider is slidably connected in the second slide groove, and one end of the slider extends into the first slide groove and is fixed to the limiting block. A threaded rod is threadedly connected to the slider.

[0014] A gear groove is formed inside a rotating rod and communicates with a second sliding groove. A first bevel gear and a second bevel gear are rotatably connected inside the gear groove and mesh with each other. One end of the first bevel gear passes through the inner wall of the gear groove and extends into the second sliding groove and is fixed to one end of a threaded rod. A rotating rod is fixedly connected to the second bevel gear, and one end of the rotating rod passes through the inner wall of the gear groove and extends to the outside and is rotatably connected to the rotating rod.

[0015] A fixing component is located on the rotating rod and is used to fix the rotating rod.

[0016] In this technical solution, the slide bar is fixed in the first slide groove, and the rotating rod and slide bar fix the locking pin in the locking hook to prevent the locking pin from shaking due to external influences.

[0017] In the above technical solution, the fixing component further includes:

[0018] A threaded groove is formed on the circumference of the rotating rod, and a threaded sleeve is threadedly connected to the threaded groove.

[0019] In this technical solution, it is ensured that the rotating rod will not be affected by external factors and will not rotate.

[0020] In the above technical solution, the threaded sleeve is made of an anti-slip material.

[0021] This technical solution ensures that the user's hand will not slip when rotating the threaded sleeve.

[0022] In the above technical solution, one end of the slider is slidably connected to the first groove.

[0023] In this technical solution, it is ensured that when the slider slides, one end of the slider can slide normally within the first groove.

[0024] In the above technical solution, one end of the first bevel gear is rotatably connected to the second sliding groove.

[0025] In this technical solution, it is ensured that when the first bevel gear rotates, one end of the first bevel gear rotates normally within the second slide groove.

[0026] In the above technical solution, the threaded rod is further located on the inner wall of the second slide groove and is rotatably connected to the second slide groove.

[0027] In this technical solution, it is ensured that when the threaded rod rotates, it rotates normally within the second groove.

[0028] The beneficial effects of this utility model are:

[0029] 1. This rapid hoisting tool for steel structure construction uses a fixed block and a rotating block to ensure that the rotating block rotates within the fixed block. A rotating groove and a rotating rod ensure that the rotating rod rotates between two rotating grooves. A first sliding groove and a sliding rod ensure that when the locking pin rotates within the hook, it drives the sliding rod to slide along the first sliding groove via the fixed block and the rotating block. A drive assembly and a limit block ensure that the user can move the limit block using the drive assembly. When the sliding rod moves to the appropriate position, the user controls the limit block to abut against the sliding rod, fixing it in place. This solves the problem that when the steel plate sways in the air, the locking pin may fail to clamp the steel plate due to the swaying of the plate, and in severe cases, the steel plate may fall off between multiple hooks.

[0030] 2. This rapid hoisting tool for steel structure construction, through its threaded groove and threaded sleeve, ensures that when the user rotates the threaded sleeve, the threaded sleeve will be acted upon by the threads of the threaded groove, moving towards the rotating rod and pressing tightly against it, thus fixing the rotating rod to the rotating rod and preventing it from rotating due to external influences.

[0037] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0038] Please see Figure 1 - Figure 4 As shown, this embodiment provides a rapid hoisting tool for steel structure construction, including a hook 1 and a pin 2, wherein the pin 2 is rotatably connected within the hook 1, and further includes:

[0039] Fixed block 3 is fixedly connected to one side of the locking pin 2, and a rotating block 4 is rotatably connected inside the fixed block 3;

[0040] Two rotating grooves 5 are symmetrically opened on the inner wall of the hook 1. A rotating rod 6 is rotatably connected between the two rotating grooves 5. A first sliding groove 7 that communicates with the outside is opened in the rotating rod 6. A sliding rod 8 is slidably connected in the first sliding groove 7, and one end of the sliding rod 8 extends to the outside and is fixed to the rotating block 4. A limit block 9 is slidably connected in the first sliding groove 7.

[0041] The drive assembly is located inside the rotating rod 6 and is used to drive the limit block 9 to slide.

[0042] The drive assembly also includes: a second slide groove 10, which is opened on one side of the first slide groove 7. A slider 11 is slidably connected in the second slide groove 10, and one end of the slider 11 extends into the first slide groove 7 and is fixed to the limiting block 9. A threaded rod 12 is threadedly connected in the slider 11.

[0043] Gear groove 13 is formed inside the rotating rod 6 and is connected to the second sliding groove 10. A first bevel gear 14 and a second bevel gear 15 are rotatably connected inside the gear groove 13 and mesh with each other. One end of the first bevel gear 14 passes through the inner wall of the gear groove 13 and extends into the second sliding groove 10 and is fixed to one end of the threaded rod 12. A rotating rod 16 is fixedly connected to the second bevel gear 15 and one end of the rotating rod 16 passes through the inner wall of the gear groove 13 and extends to the outside and is rotatably connected to the rotating rod 6.

[0044] A fixing component is located on the rotating rod 16 and is used to fix the rotating rod 16.

[0045] When the slide bar 8 moves to the appropriate position, the user manually rotates the rotating rod 16, causing the rotating rod 16 to drive the second bevel gear 15 to rotate within the gear groove 13. The second bevel gear 15 then drives the first bevel gear 14 to rotate within the gear groove 13, which in turn drives the threaded rod 12 to rotate within the second slide groove 10. This causes the slider 11 to move along the second slide groove 10 due to the thread action of the threaded rod 12. The slider 11 then drives the limiting block 9 to move towards the other end of the slide bar 8. When the limiting block 9 moves to a position where it cannot move further, it will abut against the other end of the slide bar 8, ensuring that the slide bar 8 can be fixed within the first slide groove 7. This allows the rotating rod 6 and the slide bar 8 to fix the locking pin 2 within the locking hook 1, preventing the locking pin 2 from shaking due to external influences.

[0046] The fixing component also includes a threaded groove 17, which is formed on the periphery of the rotating rod 16, and a threaded sleeve 18 is threadedly connected to the threaded groove 17.

[0047] In use, the user rotates the threaded sleeve 18 by hand, causing the threaded sleeve 18 to move towards the rotating rod 6 under the action of the threaded groove 17. This makes the threaded sleeve 18 tightly pressed against the rotating rod 6, fixing the rotating rod 16 inside the rotating rod 6 and preventing it from rotating, thus ensuring that the rotating rod 16 will not be affected by external factors and will not rotate.

[0048] The threaded sleeve 18 is made of a non-slip material, such as a skin-like coating or non-slip rubber attached to its surface. This ensures that the user's hand will not slip when rotating the threaded sleeve 18. Tightening the threaded sleeve 18 and pressing it against the side wall of the rotating rod 6 restricts the rotation of the rotating rod 16.

[0049] One end of the slider 11 is slidably connected to the first slide groove 7. This ensures that when the slider 11 slides, one end of the slider 11 can slide normally within the first slide groove 7.

[0050] One end of the first bevel gear 14 is rotatably connected to the second slide groove 10. This ensures that when the first bevel gear 14 rotates, one end of the first bevel gear 14 can rotate normally within the second slide groove 10.

[0051] The threaded rod 12 is located on the inner wall of the second slide groove 10 and is rotatably connected to the second slide groove 10. This ensures that the threaded rod 12 can rotate normally within the second slide groove 10 when it rotates.

[0052] In use, when the steel plate is placed between the upper plate of the hook 1 and the locking pin 2, the user rotates the locking pin 2 by hand so that the bottom end of the locking pin 2 abuts against the steel plate. When the locking pin 2 rotates, it drives the rotating block 4 through the fixed block 3 to move, causing the rotating block 4 to drive the sliding rod 8 to move along the first sliding groove 7. At the same time, the rotating block 4 rotates within the fixed block 3. When the sliding rod 8 moves to the appropriate position, the user rotates the rotating rod 16 by hand, causing the rotating rod 16 to drive the second bevel gear 15 to rotate within the gear groove 13, causing the second bevel gear 15 to drive the first bevel gear 14 to rotate within the gear groove 13, causing the first bevel gear 14 to drive the threaded rod 12 to rotate within the second sliding groove 10, so that the slider 11 is subjected to... The threaded rod 12 moves along the second slide groove 10, causing the slider 11 to move the limiting block 9 towards the other end of the slide rod 8. When the limiting block 9 moves to a position where it cannot move further, it will abut against the other end of the slide rod 8, ensuring that the slide rod 8 can be fixed in the first slide groove 7. This allows the rotating rod 6 and the slide rod 8 to fix the locking pin 2 in the locking hook 1, preventing the locking pin 2 from shaking due to external influences. Subsequently, the user rotates the threaded sleeve 18 by hand, causing the threaded sleeve 18 to move towards the rotating rod 6 under the action of the threaded groove 17. This causes the threaded sleeve 18 to press tightly against the rotating rod 6, fixing the rotating rod 16 within the rotating rod 6 and preventing it from rotating due to external influences.

[0053] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
