"Rigid security " it is the safety that points to machine equipment, and be not the security that covers rigid structure part only, return those who have circumjacent to machinery environment and personnel to defend safe.
The safety that is aimed at a machine defends, what equipment should consider above all is safe problem.
Mechanical equipment basis concerns safe requirement, must furnish the reasonable, reliable, safe unit that does not affect an operation. For example: (1) to making whirligig 0, the component should install fortify shield or defend fender, defend the safe guard such as baluster, happen in case wring. (2) is pressed to exceeding, overweighted, overheating is spent, between overtime, exceed the journey to wait can produce dangerous accident 0, component, should furnish insurance unit, if contact breaker of relay of excess load limiter, journey limiter, relief valve, temperature, time is waited a moment, when happening with handy and hazardous condition, remove danger condition as a result of the action of insurance unit, prevent the happening of the accident. (When 3) needs to undertake warn or remindful watchful to people to certain movement, should install pilot device or caution board. Wait for sound signal like electric bell, horn, buzzer, still all sorts of all sorts of lamplight signal, admonitory sign cards wait to belong to this kind of safe device. (4) cannot do reverse to certain movement order 0, component should furnish interlock. Namely some movement, must advanced after a movement is finished, ability undertakes, otherwise impossible movement. Assured to because the movement is ordinal,be not sent so make a mistake and produce an accident
The electric unit of mechanical equipment must accord with the requirement of electric safety, basically have the following: (The lead of 1) power supply must be installed correctly, must not have any damaged or the place that show copper. (Ying Liang of insulation of 2) electric machinery is good, its wiring board due cover board defends, contact directly in case. (3) switch, pushbutton should in good condition nondestructive, its live part is not gotten bare and outer. (The ground connection with due and good 4) or receive 0 unit, connective lead wants firm, must not have disconnecting place. (5) local lighting lamp should use the tension of 36V, taboo 1lOV or 220V voltage.
A few types of the classification that is rigid security below and give typical examples are dangerous, each engineer children's footwear, ask check the number to enter, what danger exists on the facility that visits us to design, be oversight at ordinary times.
The classification of rigid security:1.Mechanical sex is dangerous
2.Electric sex is dangerous (right, it also belongs to rigid security)
3.What heat source place causes is dangerous
4.What noise place causes is dangerous
5.Shake the risk that creates
6.What radiative place causes is dangerous
7.What stuff place causes is dangerous
8.Do not accord with human body labour to learn the risk that create
Of course, the picture of above is circumstance of one portion risk merely, more danger, everybody has fun at can examine standard EN ISO 12100-2010 " rigid security - design general rule - the risk is evaluated and the risk is reduced " ; Corresponding country level is GB/T 15706-2012 " general rule risk evaluates mechanical safety design to be reduced with the risk "
