This utility model discloses a stable transportation device for steel structure frames adapted to complex road conditions, including a truck head with a carriage connected to one side. Both the truck head and the carriage are equipped with anti-slip tires underneath. The rubber plates of this device are helically locked to the carriage via multiple sets of bolts. The multiple sets of rubber plates installed on the inner wall of the carriage further increase the interior protection of the carriage, thus preventing collisions between the steel structure frame and the carriage wall in complex road conditions. The device's fixing ring is helically locked to the rubber plates and carriage via a helical rod within a second helical hole. The steel structure frame is connected to the fixing ring via a connecting rope. After the steel structure frame is positioned in the carriage, it can be connected to the fixing ring via the connecting rope, further increasing the connection between the steel structure frame and the carriage during transportation, thereby increasing the stability of the steel structure frame during transportation in complex road conditions.

The present invention relates to the technical field of aluminum stranded wire preparation, and specifically discloses an aging-resistant aluminum stranded wire and a preparation method thereof, comprising a fixed tube, the outer surface of the fixed tube is provided with a fitting groove, the fitting groove is extended in a spiral shape, and a plurality of the fitting grooves are arranged at fixed intervals around the central axis of the fixed tube, and also comprises: an aluminum wire, the inner surface of the aluminum wire is tightly fitted in the fitting groove, and the aluminum wire is combined into a tubular aluminum stranded wire. By providing a groove on the second steel core and arranging the groove and the contact hole relative to each other, after the aluminum wire is twisted on the fixed tube, the aluminum wire will also achieve point contact and mutual engagement through the groove and the second steel core. Through this engagement method, the second steel core can be limited during use to avoid the second steel core being linearly distributed in the fixed tube and shifting to reduce the structural strength of the aluminum stranded wire. By distributing the second steel core linearly, the production time can be greatly reduced, and the production efficiency can be greatly improved.

This invention belongs to the field of mineral flotation technology, specifically relating to a forced slurry conditioning-eddy current mineralization-static separation mineral flotation system and method. It includes a slurry conditioning cylinder, a separation chamber, and a mineralization cylinder connected in sequence. The slurry conditioning cylinder contains a slurry conditioning pipeline; the separation chamber contains raw ore processing pipelines and middlings processing pipelines; and the mineralization cylinder contains an eddy current mineralization pipeline. The slurry conditioning pipeline, raw ore processing pipeline, eddy current mineralization pipeline, and middlings processing pipeline are connected sequentially. After minerals and flotation reagents are conditioned in the slurry conditioning cylinder to obtain raw ore slurry, it passes through the separation chamber to obtain middlings ore slurry, which then enters the eddy current mineralization pipeline. The middlings ore slurry returns to the separation chamber and enters the middlings processing pipeline for flotation separation. Finally, concentrate is collected at the top of the separation chamber. The mineral flow path designed in this invention enables efficient collisions between minerals of different particle sizes and slurry conditioning reagents, as well as between minerals and air bubbles, achieving effective flotation recovery.
