[0002] In factory construction, safe lifting point structures are crucial for ensuring smooth lifting operations and personnel safety. The rapid development of industrialization and the construction industry has placed higher demands on the precision, efficiency, and safety of lifting operations. Traditional lifting point structures often suffer from issues such as fixed, non-adjustable positions, complex installation, and difficult maintenance, making them unable to meet the diverse demands of modern factory construction.

[0003] Traditional lifting point structures usually consist of fixed lifting point brackets and lifting ropes. Once these lifting point brackets are installed, their positions are difficult to adjust, which brings many inconveniences in actual construction. For example, when lifting large equipment or components, due to the different sizes, weights and shapes of the equipment, the position and angle of the lifting points need to be precisely controlled to ensure the stability and safety of the objects during the lifting process. However, the fixed nature of traditional lifting point structures limits their flexibility and cannot meet this requirement. Utility Model Content

[0024] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0025] Example 1

[0026] Please refer to Figure 1-5 As shown, a safe lifting point structure for factory construction includes a lifting and mounting frame 1, and two groups of lifting point assemblies 2 are installed at the lower end of the mounting frame 1. The lifting point assembly 2 includes a hanging frame 201, and the hanging frame 201 is slidably connected to the lower end of the mounting frame 1. The inner side of the hanging frame 201 is rotatably connected to a fixed rod 204, and the inner side of the fixed rod 204 is slidably connected to a mounting rod 206. The lower end of the mounting rod 206 is clamped into the inside of the hanging frame 201, and the left and right ends of the mounting frame 1 are respectively rotatably connected to screw rods 103, and one end of the screw rod 103 extends to the outside of the mounting frame 1 to connect to a limiting assembly 3. The limiting assembly 3 includes a mounting plate 301, and the end of the mounting plate 301 is slidably connected to a limiting rod 302. One end of the limiting rod 302 is clamped into the inside of the mounting frame 1, and the other end of the limiting rod 302 extends to the outside of the mounting plate 301.

[0027] In this solution, the lifting point assembly 2 can slide at the lower end of each mounting frame 1, so that before lifting, the position of the lifting point assembly 2 can be adjusted according to the size, shape and dimensions of the object, thereby adjusting the lifting position of the object to be lifted. By moving the position of the lifting point assembly 2, the center of gravity of the object to be lifted can be adjusted, so that the object can be kept balanced and stable, and the object can be prevented from shaking during lifting.

[0028] Furthermore, the hanging object is fixed by the hanging frame 201, and the fixing rod 204 can be rotated inside the hanging frame 201 so that the other end of the fixing rod 204 is tightly fitted with the lower end inside the hanging frame 201, and is slidably engaged with the inside of the hanging frame 201 by the mounting rod 206, so that a closed rectangular frame is formed between the fixing rod 204 and the hanging frame 201, thereby locking the hanging object.

[0029] Furthermore, the rotational connection between the fixing rod 204 and the hanging frame 201 is similar to the flip-up structure of a "notebook" display screen in daily life. When rotating, the rotation angle can be maintained, which is convenient for connecting the hanging object.

[0030] Furthermore, the limiting rod 302 can slide inside the mounting plate 301 and be clamped inside the mounting frame 1, thereby fixing the screw 103 to prevent the screw 103 from rotating.

[0031] Example 2

[0032] Please refer to Figure 4-5 As shown, the upper end of the hanging frame 201 is fixedly connected with a slider 202 , and the slider 202 is threadedly connected to the screw rod 103 .

[0033] Two sets of guide grooves 203 are formed at the upper end of the hanging frame 201 , and two sets of guide rails 105 adapted to the guide grooves 203 are fixedly connected to the lower end of the mounting frame 1 , and the guide rails 105 are slidably connected to the guide grooves 203 .

[0034] Two sets of fixing springs 208 are fixedly connected inside the fixing rod 204. The end of the fixing spring 208 away from the fixing rod 204 is fixedly connected to the mounting rod 206. A mounting groove 209 is opened on the inner side of the hanging frame 201, and the lower end of the mounting rod 206 is clamped inside the mounting groove 209.

[0035] A limiting groove 205 is provided on the outer side of the fixing rod 204 , and a sliding rod 207 is fixedly connected to the outer side of the installation rod 206 . The sliding rod 207 is slidably connected to the limiting groove 205 .

[0036] In this solution, the rotation of the screw rod 103 drives the slider 202 to allow the hanging frame 201 to move and adjust on the guide rail 105;

[0037] Furthermore, the fixing spring 208 can push the mounting rod 206 to automatically enter the interior of the mounting slot 209, thereby fixing the fixing rod 204 to the hanging frame 201;

[0038] Furthermore, the upward movement of the slide bar 207 can drive the installation bar 206 to move upward, so that the installation bar 206 moves from the inside of the installation slot 209 to the inside of the fixing bar 204, thereby releasing the fixed connection between the fixing bar 204 and the hanging frame 201.

[0039] Example 3

[0040] Please refer to Figure 3 As shown, the middle of the limiting rod 302 is fixedly connected to the limiting plate 304 , the middle of the limiting rod 302 is sleeved with a limiting spring 303 , and both ends of the limiting spring 303 are fixedly connected to the limiting plate 304 and the mounting plate 301 respectively.

[0041] The left and right ends of the mounting frame 1 are respectively provided with limiting holes 104 adapted to the limiting rod 302 , and one end of the limiting rod 302 is clamped in the inside of the limiting hole 104 .

[0042] In this solution, after the position of the hanging point assembly 2 is adjusted, the limit spring 303 can push the limit plate 304 so that the limit rod 302 is engaged with the inside of the limit hole 104, thereby fixing the screw 103. When the position of the hanging point assembly 2 is adjusted, the limit rod 302 can be pulled out and the mounting plate 301 can be driven to rotate, thereby driving the screw 103 to rotate.

[0043] Example 4

[0044] Please refer to Figure 1 As shown, a lifting frame 101 is fixedly installed on the upper end of the mounting frame 1 , and a lifting ring 102 is fixedly connected to the top of the lifting frame 101 .

[0045] In this solution, the lifting frame 101 is fixedly connected to the mounting frame 1 through bolts and is connected to an external lifting device through a lifting ring 102.

[0046] The working principle and usage process of the present invention are as follows: First, before hoisting, fix the hanging frame 201 and the hanging object, and rotate the fixing rod 204 to fit tightly with the lower end of the inner side of the hanging frame 201, so that the mounting rod 206 is clamped into the inside of the hanging frame 201, thereby locking the hanging object. After that, pull out the limit rod 302 and drive the mounting plate 301 to rotate, thereby driving the screw 103 to rotate, driving the slider 202 to make the hanging frame 201 move and adjust on the guide rail 105, and then adjust the position of the hanging point assembly 2 according to the size, shape and size of the object, adjust the center of gravity of the hanging object, so that the hanging object remains balanced and stable, and prevents the hanging object from shaking during hoisting. After the adjustment is completed, loosen the limit rod 302 and align it with the limit hole 104, so that the limit rod 302 is clamped into the inside of the limit hole 104, and then fix the screw 103, and then hoist through the external lifting device.
