The brake is an important brake device, which is the entire working process of the brake when the machine stops running.
Generally speaking, the brake is installed on the equipment of a widget, but because it's so important that can be said to be the relation to the safety of the engineering construction and staff personal safety problems, we should pay more attention to.
Therefore, in daily work, every shift staff needs to check it, so that the brake can operate normally.
However, the time of use of the brake is too long, and there will inevitably be various problems, such as brake wheel damage, brake belt or brake block, and the brake overheat in the working process.
These will make the operation of the brake unstable or even affect the work safety, so the brake should be taken seriously when these problems occur and should be scrapped when the following conditions are met.
(1) the crack;
(2) the thickness of the brake belt or brake pad is 50% of the thickness of the original thickness;
(3) plastic deformation occurs in spring;
(4) the diameter of the hinge shaft or shaft hole is 5 percent of the original diameter;
(5) when the braking wheel appears in one of the following situations, it shall be scrapped:
The brake wheel of the hoisting and amplifying mechanism is about 40% of the thickness of the flange.
The brake wheel of other institutions, the thickness of the flange is 50% of the original thickness;
If the concave and convex surface of the wheel is up to 1.5mm, if it can be repaired, the thickness of the flange should meet the requirements of the first and the second part of this article.
