2results about How to "Frictional stability" patented technology

This invention discloses a water washing tank and production line for single-strand high-speed hot-dip galvanizing, relating to the field of metal surface treatment technology. It aims to solve the technical problem that simply relying on circulating water rinsing may not be sufficient to completely remove some strongly adhering metal debris and particles from the surface of steel wire. The system includes a wire feeding frame, a sanding cloth belt machine, a wire drawing machine, a wiping device, a fluxing tank, a drying device, a galvanizing tank, a cooling device, and a wire unloading machine. The water washing tank is positioned between the wire drawing machine and the wiping device. The water washing tank includes a first circulating water tank, a circulating flushing chamber, a second circulating water tank, and a reclaimed water tank. A debris removal component is arranged between the first circulating water tank and the circulating flushing chamber. This component can scrape and rub the outer surface of the steel wire to remove the metal particles adhering to it. This invention has the advantage of improving the cleaning effect on steel wire through multiple cleaning methods.

The application relates to the technical field of ship parking production, and discloses a rope climbing machine for quickly hoisting a water pump, which comprises a shell and a rope wheel, a guide wheel is rotationally connected to the middle part of the inner cavity of the shell, a rope is jointly wound around the rope wheel and the guide wheel, an extrusion block is arranged at the top of the upper extrusion part, a fixed block is arranged at the bottom of the lower extrusion part, an extrusion groove with the same direction as the lower extrusion part is arranged at the top of the fixed block, and the lower extrusion part is movably connected in the extrusion groove. The device realizes the preliminary braking effect on the rope through the extrusion of the extrusion block, the upper extrusion part and the lower extrusion part of the rope are extruded with each other, significant frictional resistance is generated, the movement of the rope in the extrusion groove is effectively prevented, the braking performance during falling is enhanced, the tensioning part of the rope is subjected to downward pressure by the tensioning wheel to tighten the rope, so that the stable friction between the rope and the rope wheel is ensured, and the risk of slipping is effectively reduced.
