| 摘 要： | 依次给出了提升机综合后备保护装置减速点到停车位距离的粗略计算公式、某段(点)到停车位的安全制动距离计算公式、某段(点)到停车位的超速持续判断安全制动距离的计算公式及减速点到停车位的超速持续判断安全制动距离的计算公式,在井口下与井口相距该安全制动距离的点即设置为减速点。该方法适用于提升机电控系统减速点随载重量自动调整时后备保护减速点的设置。应用结果表明,根据该方法设置的提升机综合保护装置减速点可保证在提升机电控系统减速点失效后使提升容器在井口以下安全停车,可靠性高。 |

Setting method of deceleration point of integrated backup protection device of hoist |
|
| Abstract: | The paper gave rough formula of distance between deceleration point of integrated backup protection device of hoist and stop point,and calculation formulas of safe braking distance between a section or a point and stop point,safe braking distance of continual over speed judgment between a section or a point and stop point,and safe braking distance of continual over speed judgment between deceleration point and stop point successively.The point which is away pithead with the safe braking distance of continual over speed judgment between deceleration point and stop point is set as deceleration point.The setting method of deceleration point is fit for setting deceleration point of backup protection when deceleration point of electrical control system of hoist adjusts automatically according to loads.The application shows that deceleration point set by the method can ensure hoisting container stop under pithead safely when deceleration point of electrical control system of hoist loses efficacy with high reliability. |
