Problems solved by technology

During the engagement process of the brake shoe assembly and the brake wheel, the friction plate of the brake shoe assembly heats up very rapidly. If the temperature is not cooled in time, the friction plate will be easily damaged due to continuous engagement for a long time; and the traction machine is installed in the external environment , Dust, impurities, etc. are easy to fall on the brake wheel of the traction machine, thereby affecting the cohesion between the brake wheel and the brake shoe assembly, and it is easy to scratch the surface of the brake wheel and the friction plate during the cohesion process

Moreover, the brake shoe assembly is continuously engaged and separated from the brake wheel for a long time, which leads to serious wear of the brake shoe assembly. The friction plate on the brake shoe assembly is easily damaged, and its surface tends to become relatively smooth, resulting in In order to reduce the cohesive force of the brake shoe assembly to the brake wheel, it is difficult to stop the traction machine in time. Therefore, it is necessary to be able to detect the size of the cohesive force of the brake shoe assembly to the brake wheel.

Moreover, the structure of the existing friction plate is not reasonable, and the installation is more complicated, and the force of the brake shoe on the friction plate is not enough, so it is difficult to ensure a good connection between the two

[0003] In general, the friction lining of the existing traction machine is damaged quickly, the installation of the friction lining is complicated, and the wear condition of the friction lining cannot be monitored in a timely manner.
