[0024] 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.

[0025] Please see Figures 1 to 4 The present invention provides a technical solution: a steel cage lowering platform, including a steel platform 1, a hole protection steel plate 2 fixedly connected to the inner side of the steel platform 1, and a steel casing 3 fixedly connected to the inner side of the hole of the hole protection steel plate 2. The front of the steel platform 1 is provided with a support component for supporting and limiting the steel cage.

[0026] like Figure 1 As shown, the support assembly includes four fixed steel plates 4 fixedly connected to the front of the steel pedestal 1, a frame 5 fixedly connected to the side wall of the fixed steel plates 4, a threaded rod 6 rotatably connected to the inner side wall of the frame 5, a threaded block 7 threaded to the outside of the threaded rod 6, two connecting rods 8 fixedly connected to the side wall of the threaded block 7, a connecting plate 9 fixedly connected between the other ends of the two connecting rods 8, and a support plate 10 fixedly connected to the other side of the connecting plate 9.

[0027] It should be noted that the four fixed steel plates 4 are respectively arranged at the top, bottom, left and right sides of the front of the steel pedestal 1, forming symmetrically distributed support points. This arrangement ensures that the support components can be evenly stressed from four directions, preventing the steel cage from shifting or tilting during hoisting or lowering. The fixed steel plates 4 and the steel pedestal 1 are fixedly connected by welding to ensure their stability and load-bearing capacity.

[0028] The left frame 5 is fixedly connected to the left side wall of the left fixed steel plate 4, the right frame 5 is fixedly connected to the right side wall of the right fixed steel plate 4, the top frame 5 is fixedly connected to the upper surface of the top fixed steel plate 4, and the bottom frame 5 is fixedly connected to the bottom side wall of the bottom fixed steel plate 4.

[0029] The left threaded rod 6 is rotatably connected to the inner right side wall of the left frame 5, the right threaded rod 6 is rotatably connected to the inner left side wall of the right frame 5, the top threaded rod 6 is rotatably connected to the inner bottom wall of the top frame 5, and the bottom threaded rod 6 is rotatably connected to the inner top wall of the bottom frame 5. A torsion cap 601 is fixedly connected to the end of the threaded rod 6 away from the inner side wall of the corresponding frame 5, so that the operator can adjust the rotation angle of the threaded rod 6 by manually rotating the torsion cap 601, thereby controlling the movement of the threaded block 7.

[0030] The inner sides of the four fixed steel plates 4 are provided with through holes that are compatible with the connecting rods 8. The opposite side walls of the left and right frame bodies 5 are provided with sliding holes that are compatible with the connecting rods 8. The opposite side walls of the upper and lower frame bodies 5 are also provided with sliding holes that are compatible with the connecting rods 8, and the sliding holes are connected to the corresponding through holes.

[0031] Limiting rings 11 are fixedly connected to both the front and back of the threaded block 7, and limiting rods 12 are slidably connected to the inner side of the limiting rings 11. The limiting rods 12 on the left and right sides are fixedly connected between the inner left side wall and the inner right side wall of the corresponding frame 5, respectively. The limiting rods 12 on the upper and lower sides are fixedly connected between the inner top wall and the inner bottom wall of the corresponding frame 5, respectively. The limiting rods 12 are used to limit the threaded block 7, prevent the threaded block 7 from rotating or deviating during movement, and ensure that the threaded block 7 moves in a straight line.

[0032] The top and bottom of the steel pedestal 1 are fixedly connected with first reinforcing plates 13. Two second reinforcing plates 14 are fixedly connected between the opposite side walls of the two first reinforcing plates 13. Reinforcing ribs 15 are fixedly connected to the opposite side walls of the two second reinforcing plates 14. The two second reinforcing plates 14 are located on the left and right sides of the steel pedestal 1, respectively. The right end of the left reinforcing rib 15 is fixedly connected to the left side wall of the steel pedestal 1, and the left end of the right reinforcing rib 15 is fixedly connected to the right side wall of the steel pedestal 1. The first reinforcing plates 13, the second reinforcing plates 14 and the reinforcing ribs 15 together form a rigid frame structure, which further enhances the overall strength and stability of the steel pedestal 1 and ensures that it will not deform or be damaged when bearing the weight of the reinforcing cage.

[0033] The working principle of the above embodiments is as follows:

[0034] One end of the reinforcing cage is placed inside the steel casing 3. Then, the operator drives the threaded rod 6 to rotate by rotating the torsion cap 601. Since the threaded rod 6 and the threaded block 7 are connected by threads, the threaded block 7 moves axially under the rotation of the threaded rod 6. The movement of the threaded block 7 drives the connecting rod 8 and the connecting plate 9 to move synchronously, thereby pushing the support plate 10 to move towards the reinforcing cage. Under the push of the connecting rod 8, the support plate 10 is gradually inserted into the gap of the reinforcing cage from the top, bottom, left and right sides, forming support and limiting for the reinforcing cage. When the support plate 10 is fully inserted into the gap of the reinforcing cage, the reinforcing cage is fixed on the steel pedestal 1. Under the support and limiting effect of the support plate 10, the reinforcing cage can be smoothly lowered to the target position.
