A bath pedal convenient to install comprises a pedal body, and a containing area capable of containing a lifting rope is arranged at the bottom of the pedal body. A hollow pipe is installed at the bottom of the pedal body, and the interior of the hollow pipe is hollow to form a containing area. And the hollow pipe is fixed at the bottom of the pedal body through an adhesive. The bath pedal has the advantages that the containing area capable of containing the lifting rope is innovatively arranged at the bottom of the bath pedal body, and the core advantage of the structure is that an acting point is provided for the installation process. During installation, installation personnel can enable a lifting rope to penetrate through the hollow flat pipes arranged at the bottom of the pedal. Afterwards, the two persons can respectively pull the two ends of one lifting rope, and the whole bath pedal can be horizontally lifted easily and stably like a lifting handle. The problem that in the prior art, due to the fact that pedals are heavy and lack suitable grabbing points, force is difficult to apply especially in narrow spaces such as three faces leaning against the wall is thoroughly solved.

This invention discloses a refractory spraying system and method for tundishes. The system includes guide rail modules laid along three tundish workstations, a work machinery unit equipped with a six-degree-of-freedom robotic arm, a lifting drive mechanism, modular work components integrating electrical and pneumatic connection modules, a quick-change material box, and a central control system. The six-degree-of-freedom robotic arm's range of motion can cover the entire area inside the tundish. The work method adopts a three-station continuous operation mode, precisely matching the process time of refractory spraying and drying. It can also switch between high-speed and low-speed spraying modes to adapt to different tundish wall temperatures and is equipped with a standardized construction process. This invention achieves no idle time for the work machinery, improves construction efficiency and spraying quality, eliminates blind spots in construction operations, has a high degree of automation throughout the process, low equipment maintenance costs, strong system versatility, and can adapt to the needs of industrialized batch construction.
