Description

Technical Field

[0001] The utility model relates to the field of auxiliary tools for making steel reinforcement cages, and particularly relates to a rotary support bracket for a steel reinforcement cage. Background Art

[0002] When manufacturing a steel reinforcement cage, it is often processed by welding in three layers from the inside to the outside in sequence, namely the inner ring (also known as the reinforcement bar), the main reinforcement bars (also known as straight bars), and the spiral reinforcement bars (also known as stirrups). According to different processes, the semi-finished product after welding the inner ring and the main reinforcement bars is called the steel reinforcement cage skeleton, and the main reinforcement bars are welded to the outside of the inner ring. When welding the spiral reinforcement bars to the steel reinforcement cage skeleton, the current process is to rotate it around the central axis, and while rotating, the spiral reinforcement bars are welded to the steel reinforcement cage skeleton.

[0003] In the existing technology, there is a technology that uses roller rotation to drive the steel reinforcement cage or the steel reinforcement cage skeleton to rotate. As Figure 7 shown, when rotating the steel reinforcement cage skeleton with this technology, the rollers are circular, and the main reinforcement bars on the skeleton are welded to the outside of the inner ring. A gap will be formed between adjacent main reinforcement bars. When rotating, the rollers will get stuck in this gap, causing the steel reinforcement cage to vibrate continuously, which greatly affects the welding quality of the spiral reinforcement bars. At the same time, the steel reinforcement cage is generally heavy, and the rollers getting stuck in the gap will also generate a lot of noise, affecting the production environment. Content of the Utility Model

[0004] The purpose of the utility model is to provide a rotary support bracket for a steel reinforcement cage. By forming a V-shaped transmission cavity that supports and drives the steel reinforcement cage to rotate with the support part provided at the upper end of the bracket body, and the length of the support part is greater than the gap between adjacent main reinforcement bars of the steel reinforcement cage skeleton, when the steel reinforcement cage rotates, the continuous vibration of the steel reinforcement cage caused by the rollers getting stuck in the gap is avoided, and the welding quality of the spiral reinforcement bars is greatly improved.

The specific number can be determined according to the actual situation. The transmission wheel set 1 includes a support part 7, and a V-shaped transmission cavity 5 is formed between adjacent support parts 7. The transmission cavity 5 supports and drives the steel reinforcement cage 6 to rotate. Moreover, the length of the support part 7 is greater than the gap between adjacent main reinforcements of the steel reinforcement cage 6 skeleton, so that when the steel reinforcement cage 6 rotates, it avoids the continuous vibration of the steel reinforcement cage 6 caused by the roller shaft getting stuck in the gap, greatly improving the welding quality of the spiral reinforcement.

[0043] Among them, please refer to Figure 5 As shown, the transmission wheel set 1 includes two or more parallel transmission wheels. The distance between adjacent transmission wheels is adjustable and drives the support part 7 to rotate around the outer edge of the transmission wheel. Specifically, in this embodiment, the transmission wheel set 1 includes a mounting plate 11, a secondary transmission wheel 8 and a primary transmission wheel 9. The secondary transmission wheel 8 and the primary transmission wheel 9 are both connected to the mounting plate 11 through threaded holes. By adjusting the relative positions of the secondary transmission wheel 8 and the primary transmission wheel 9 on the mounting plate 11, the length of the support part 7 is adjusted. As Figure 6 shown, the length of the support part 7 must be greater than the gap between adjacent main reinforcements of the steel reinforcement cage 6 skeleton. Here, the support part 7 is a transmission belt and is tensioned on the outer peripheries of the secondary transmission wheel 8 and the primary transmission wheel 9. The primary transmission wheel 9 is driven by driving the first transmission shaft 10 by a motor (not shown in the figure), so that the support part 7 drives the steel reinforcement cage 6 to rotate.

[0044] Meanwhile, in order to form a stable V-shaped transmission cavity 5 between adjacent support parts 7, the transmission wheel set 1 further includes a mounting bottom plate 12, a fixing plate 13 and a mounting side plate 14.

Adjusting holes 17 matching the first adjusting plate 15 are provided on both sides of the second adjusting plate 16. The adjusting holes 17 are arrayed along the length direction of the mounting bracket 19. The first adjusting plate 15 is also fixedly connected to the cage 2. When it is necessary to adjust the distance between the relatively arranged cages 2, the position of the first adjusting plate 15 on the second adjusting plate 16 can be adjusted.

[0047] In some embodiments, a limiting plate 18 is provided on each of the two end faces of the mounting bracket 19 to prevent the cage 2 from falling off when the distance is adjusted.
