Description

Technical Field

[0001] The utility model relates to the technical field of coiled steel bar processing, in particular to an adjustable coiled steel bar processing protective device. Background Art

[0002] Rebars are used in large quantities in construction projects. After leaving the factory and being transported to the construction site, coiled steel bars are placed in coils. When the coils are extracted for straightening, the weight of the coils limits their up and down swings, while if there is no restriction on left and right, they will swing left and right. At this time, a protective device is needed to prevent them from swinging left and right, thereby improving safety.

[0003] The traditional coil processing protective device consists of a protective tube and a support frame. When in use, the coil is connected from the inside of the protective tube to the feed port of the straightening machine for processing. The protective tube is used to prevent the coil from swinging left and right during processing, while the support frame limits the overall displacement caused by the vibration of the protective tube. CN202020226778.5 first proposed a coil processing protective device. The protective device is welded as a whole, and the device is fixed to the ground with bolts to prevent it from moving sideways. CN202021150976.4 provides a protective frame provided with supporting steel bars and rolling steel pipes, which can pre-modulate the steel bars and place tool boxes, and the functionality is improved. In patent CN202321902818.3, on the basis of the connection between the protective tube and the bracket, a detachable leg is added to adjust the position of the protective device, and the stability of the device is further improved. In general, these protective devices still have some defects: the protective tube and the support frame are rigidly connected as a whole. Due to manufacturing deviations, inconsistent straightening machine models, and site reasons, the height of the protective tube and the feed port of the straightening machine are often inconsistent, and the inner diameter of the protective tube at the feed port is small. In this case, it is very easy to cause the coil to swing up and down, affecting the processing quality of the coil, the service life of the straightening machine, and the processing safety. In addition, the protective device cannot be disassembled after use, and collision deformation may occur during turnover and transportation.

[0004] Therefore, the known coiled steel bar processing protection device structural form has the above-mentioned various inconveniences and problems. Utility Model Content

The supporting crossbar has threads on both sides and in the middle, and is the main force-bearing component supporting the protective tube. The threads on both sides are used for the anchor ring to tighten and clamp the vertical plates on both sides, and the middle thread is used for the anchor ring to tighten and clamp the lock buckle; the inner side of the anchor ring has matching threads for clamping the vertical plates and the lock buckle on both sides;

[0009] The connecting piece includes a lock buckle and an anchor bolt. The inner side of the upper part of the connecting piece limits lateral displacement, and the outer side is fastened with the protective tube ring steel bar and then fixed with bolts.
