[0025] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the following will clearly and completely describe the technical solutions in the embodiments of this application with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are some, but not all, of the embodiments of this application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts shall fall within the scope of protection of this application.

[0026] The embodiments of this application provide a hoisting device for a steel reinforcement cage, which can solve the problem in the related art that during the hoisting of the steel reinforcement cage, it is prone to tilt, which is not conducive to the hoisting operation.

[0027] See Figures 1 to 3 As shown, the embodiments of this application provide a hoisting device for a steel reinforcement cage, including a suspension bracket 4, a slide rail 1, and a lifting ring 3. The slide rail 1 is fixedly connected to the suspension bracket 4; the lifting ring 3 is slidably connected to the slide rail 1. The lifting ring 3 includes a suspension hole area 31 and a lapping area 32 connected to the suspension hole area 31, and the lapping area 32 laps on the slide rail 1. In actual use, since the lifting ring 3 is slidably connected to the slide rail 1, the lifting ring 3 can be adjusted according to the actual situation, so that the lifting ring 3 slides along the slide rail 1 to a suitable position, so that the steel wire ropes 6 connected to the lifting ring 3 are adjusted, facilitating the multiple steel wire ropes 6 to maintain consistent force when hoisting the steel reinforcement cage, and ensuring uniform force on the lifting points, which helps the smooth progress of the hoisting work.

[0028] The lifting ring 3 includes a suspension hole area 31 and a lapping area 32 connected to the suspension hole area 31. The suspension hole area 31 is used to connect the steel wire ropes 6, and the lapping area 32 can be used to lap the lifting ring 3 on the slide rail 1, enabling the lifting ring 3 to slide along the slide rail 1. As Figure 3 shown, in some usage scenarios, the lifting ring 3 is generally in an "丄" shape as a whole, and the slide rail 1 is a "匚"-shaped semi-enclosed structure, enabling the lapping area 32 of the lifting ring 3 to lap on the slide rail 1, thus ensuring that the lifting ring 3 can slide along the slide rail 1.

[0029] Generally, during the hoisting process, a hoisting tool is used to distribute the load to several steel wire ropes 6. For traditional hoisting tools, the steel wire ropes 6 are directly connected to the hoisting beam. However, after installation, there will inevitably be certain errors between the steel wire ropes 6, and it is not convenient to adjust the steel wire ropes 6. It is difficult to ensure that the lengths of the steel wire ropes 6 are exactly the same, which will cause adverse effects such as tilt during hoisting, resulting in uneven force on the lifting points. However, through the setting that the lifting ring 3 is slidably connected to the slide rail 1, the lifting ring 3 connected to the steel wire ropes 6 can be slid to adjust the force on the steel wire ropes 6, ensuring uniform force on the steel wire ropes 6 and preventing adverse phenomena such as tilt during hoisting, which helps the smooth progress of the hoisting work.

[0030] In some optional embodiments, the slide rail 1 is arranged in a "cross" shape, and four lifting rings 3 are provided. The setting of the "cross"-shaped slide rail 1 can make the lifting ring 3 slide to the position to be moved to in a shorter distance when sliding along the guide rail. There are four lifting rings 3, and the four lifting rings 3 are respectively connected to four steel wire ropes 6. Since the slide rail 1 is arranged in a "cross" shape, the steel wire ropes 6 connected to the four lifting rings 3 are respectively located around the steel cage, which can ensure uniform force during lifting, making the lifting work reliable.

[0031] In some optional embodiments, the hanger 4 is square, and the ends of the slide rail 1 are fixedly arranged at each end of the hanger 4. The slide rail 1 is arranged in a "cross" shape, and the hanger 4 is square, and the four ends of the slide rail 1 are respectively located at the four corners of the hanger 4, thereby ensuring the stability of the structure.

[0032] In some optional embodiments, a limiting plate for limiting the sliding of the lifting ring 3 is provided on the slide rail 1. When the lifting ring 3 slides to a suitable position along the slide rail 1, the limiting plate can be used to limit and fix the lifting ring 3 to prevent the lifting ring 3 from sliding and ensure the stability of the wire rope 6 during lifting. Specifically, two limiting plates can be provided, which are respectively provided on both sides of the lifting ring 3. When the lifting ring 3 moves to a suitable position, the two limiting plates are moved to both ends of the lifting ring 3, and the limiting plates can be fixed to the slide rail 1 by using the clamping plates on the limiting plates, so as to complete the limiting of the lifting ring 3.

[0033] In some optional embodiments, the slide rail 1 is provided with a plurality of clamping grooves for limiting the lifting ring 3 at intervals along the length direction. The clamping groove is provided at the bottom of the slide rail 1, and when the lifting ring 3 moves to a suitable position along the slide rail 1, the overlap area 32 of the lifting ring 3 can fall into the clamping groove to limit the lifting ring 3 and ensure reliability during lifting.

[0034] In some optional embodiments, a slide rail 1 is fixedly connected to the top and bottom surfaces of the hanger 4, respectively, and a lifting ring 3 is slidably connected to each slide rail 1 on the side away from the hanger 4. In actual use, a hanger 4 can be provided, and slide rails 1 are provided on the top and bottom surfaces of the hanger 4, and a lifting ring 3 is slidably connected to each slide rail 1 on the side away from the hanger 4. Slide rails 1 are provided on the top and bottom surfaces of the hanger 4, and the slide rail 1 on the bottom surface is slidably connected to the lifting ring 3 for connecting the steel cage through the steel wire rope 6. In actual use, the lifting ring 3 is slidably connected to the slide rail 1.

[0035] Therefore, the lifting ring 3 can be adjusted according to the actual situation, so that the lifting ring 3 slides to a suitable position along the slide rail 1, so that the steel wire rope 6 connected to the lifting ring 3 can be adjusted, so that multiple steel wire ropes 6 can maintain consistent force when lifting the steel cage, and ensure that the force of the lifting point is uniform, which is conducive to the smooth progress of the lifting work. The slide rail 1 is also provided on the top surface of the hanger 4, and the lifting ring 3 is slidably connected to the slide rail 1. In actual use, the lifting ring 3 can be slid as needed, so that when the steel wire rope 6 on the lifting ring 3 is connected to the crane, it can be moved to a suitable lifting position to ensure uniform force.

[0036] In some embodiments, Figure 1 and Figure 2 As shown, the hanger 4 is arranged in two layers at intervals along the vertical direction, the top surface of the upper hanger 4 is provided with a slide rail 1, and the bottom surface of the lower hanger 4 is provided with a slide rail 1, and the two hangers 4 are connected and fixed by a fixing rod 5. In this arrangement, the top surface of the upper hanger 4 is provided with a slide rail 1, and the slide rail 1 is slidably connected with a lifting ring 3 for connecting the crane, and the lifting ring 3 can be used to slide and adjust the lifting point to ensure that the crane is uniformly stressed during lifting. The bottom surface of the lower hanger 4 is provided with a slide rail 1, and the slide rail 1 is slidably connected with a lifting ring 3, and the lifting ring 3 is connected with a steel wire rope 6. According to actual conditions, the lifting ring 3 can be adjusted so that the lifting ring 3 slides along the slide rail 1 to a suitable position, so that the steel wire rope 6 connected to the lifting ring 3 can be adjusted, so that multiple steel wire ropes 6 can maintain consistent stress when lifting the steel cage, and ensure that the lifting point is uniformly stressed, which helps to smoothly carry out the lifting work. In actual use, the two layers of hangers 4 are connected and fixed by the fixing rods 5, which can ensure the stability of the structure and thus ensure the smooth progress of the lifting work.

[0037] In some optional embodiments, the slide rail 1 and the hanger 4 are fixedly connected by high-strength bolts to ensure structural stability. In some embodiments, a steel plate 2 for reinforcement is fixedly arranged at the center of the slide rail 1 to make the structure more stable, thereby ensuring reliable hoisting.
