Technical Field

[0001] This utility model belongs to the field of steel cage preparation technology, specifically relating to a spiral hoop winding device for steel cages. Background Technology

[0002] With the continuous development of the construction industry, rebar cages have been widely used in various construction projects, especially in pile foundation construction of bridges, high-rise buildings, and large-scale infrastructure. The quality and production efficiency of rebar cages have a significant impact on the overall project progress and quality. The winding of the spiral stirrups in the rebar cage is one of the key steps in rebar cage production, and its winding quality directly affects the structural strength and stability of the rebar cage.

[0003] In recent years, with the advancement of technology, some spiral stirrup winding equipment for steel cages has begun to be used. For example, a stirrup winding device for pile foundation steel cages with patent number 202111482194.X includes two frame plates arranged side by side; both frame plates are rotatably connected to a rotating shaft; two support rollers are rotatably connected between the two frame plates, and a support plate is fixedly connected; the two support rollers are located below the rotating shaft; the two support rollers and the rotating shaft are distributed in an isosceles triangle, and the two support rollers are located at the base. Although the above device can realize the preparation of steel cages, it has certain shortcomings in actual use: the structure of the device used to fix the main reinforcement is complex, which brings great inconvenience to use.

[0023] like Figures 1-5As shown, a spiral stirrup winding device for a steel cage includes a spiral stirrup conveying device and a main reinforcement rotation and fixing device. The main reinforcement rotation and fixing device includes symmetrically arranged main reinforcement fixing devices, each including an end plate 1. A drive shaft 2 is provided in the middle of the end plate 1, and one end of the drive shaft 2 is fixed to the end plate 1. The edge circumference of the end plate 1 is provided with several first through holes 4 (larger than the diameter of the main reinforcement 11, facilitating the insertion of the main reinforcement 11). A pressure plate 6 is slidably sleeved on the drive shaft 2, and the edge circumference of the pressure plate 6 is provided with several second through holes 9 (also larger than the diameter of the main reinforcement 11). The positions of the second through hole 9 and the first through hole 4 are arranged in a one-to-one correspondence. A conical rubber plug 10 is provided on the end of the second through hole 9 facing the end plate 1. The large diameter end of the conical rubber plug 10 is fixed on the pressure plate 6, and the small diameter end of the conical rubber plug 10 is set towards the first through hole 4. A conical hole 12 is provided on the outside of the end of the first through hole 4 facing the pressure plate 6. The small diameter end of the conical hole 12 is set beyond the middle of the first through hole 4. A third through hole 13 is provided in the middle of the conical rubber plug 10. A drive assembly for driving the pressure plate 6 to move towards the end plate 1 is provided on the drive shaft 2.

[0024] The working principle of the above technical solution is as follows:

[0025] First, the main reinforcing bar 11 is inserted into several first through holes 4, second through holes 9, and third through holes 13 in two symmetrically arranged main reinforcing bar fixing devices. Then, the pressure plate 6 is moved towards the end plate 1 by the drive assembly. During the movement of the pressure plate 6, the conical rubber plug 10 is driven into the first through hole 4. Under continuous pressure, the conical rubber plug 10 is squeezed and deformed in the conical hole 12, thereby squeezing the end of the main reinforcing bar 11 and fixing it. This ensures the stability and effectiveness of the main reinforcing bar 11 rotating and winding the spiral stirrup. This main reinforcing bar fixing device has a simple structure and ingenious design. It does not require many additional electronic components to fix the main reinforcing bar 11, simplifying the structure of the main reinforcing bar 11 rotation device and improving ease of use.

[0026] In one feasible embodiment, the drive assembly includes an external thread 3 disposed on the drive shaft 2, and a locking nut 8 is threaded onto the external thread 3. The locking nut 8 is used to press the conical rubber plug 10 against the conical hole 12. By moving the locking nut 8 on the drive shaft 2, the pressure plate 6 can be moved, thereby pressing the conical rubber plug 10 on the pressure plate 6 against the conical hole 12, thereby fixing the main rib 11. This fixing structure is relatively simple and can simultaneously fix several main ribs 11 by moving the locking nut 8, resulting in high fixing efficiency.

[0027] In one feasible embodiment, the pressure plate 6 has a fourth through hole 14 in the middle, and the fourth through hole 14 is slidably sleeved on the drive shaft 2.

[0028] In one feasible embodiment, a plurality of limiting rods 5 are provided circumferentially on the side of the end plate 1 facing the pressure plate 6. One end of the limiting rod 5 is fixed to the end plate 1. The pressure plate 6 is provided with a plurality of limiting holes 7 corresponding to the limiting shaft. The limiting shaft is slidably connected in the limiting hole 7 to restrict the rotational freedom of the pressure plate 6. The setting of the limiting rods 5 allows the pressure plate 6 to move on the limiting rods 5, but not to rotate, ensuring the alignment effect between the second through hole 9 on the pressure plate 6 and the first through hole 4 on the end plate 1, and improving the convenience of inserting the main reinforcement 11.

[0029] In one feasible embodiment, the main reinforcement rotation and fixing device further includes a main reinforcement rotation device, which includes a mounting platform 15, with support legs 16 at the four corners of the mounting platform 15, and upright plates 18 symmetrically arranged on the mounting platform 15. The other end of the drive shaft 2 is rotatably connected to the upright plate 18, and a rotary motor 19 is provided on the outer side of at least one upright plate 18 (two installations are also possible, but a control system is needed to control the synchronous movement of the two). The output end of the rotary motor 19 is fixedly connected to the drive shaft 2, and the spiral stirrup conveying device 20 is slidably arranged on the side of the mounting platform 15.

[0030] The drive shaft 2 is rotated by the rotary motor 19, which in turn rotates the main rib 11 arranged on it. This, in conjunction with the spiral hoop conveying device 20 that slides along the mounting platform 15, allows the spiral hoop to be evenly wound around the main rib 11. It is easy to understand that the ends of the spiral hoop need to be welded to the main rib 11 first. Secondly, the spiral hoop conveying device 20 is existing technology. It can be moved on the mounting platform 15 by means of a sliding table or other transverse components. The spiral hoop can be conveyed by guide wheels that are set in opposite directions (or it can be manually tensioned and conveyed). For the specific structure, please refer to the prior art in the background section. It will not be elaborated on here.

[0031] In one feasible embodiment, at least one upright plate 18 is provided with a slide 17 at the connection between it and the mounting platform 15. The slide 17 is fixed on the mounting platform 15, and the upright plate 18 is fixed on the slider of the slide 17. The setting of the slide 17 can change the spacing between the two sets of main reinforcement fixing devices, thereby matching the preparation of steel cages of different lengths. At the same time, after the preparation is completed, the end of the prepared steel cage can be easily removed by moving one set of main reinforcement fixing devices outward.

[0032] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
