根据安全规程新规定，应用工程设计近似方法原理探讨多绳摩擦提升防滑安全校核的简化。在建立的最简多绳摩擦提升系统正常提升及安全制动两个基本动防滑公式中，引进了新的井筒阻力系数概念；对其它形式摩擦提升则以这两个基本公式为基础，采用一个简单系数修正。静、动防滑校验都与静张力比相关，并可借助表格进行。 According to the new rules of safety regulations, the principle of approximation method of engineering design is used to explore the simplification of multi-rope friction lifting anti-slip safety check. In the two basic basic slip-resistance formulas of the simplest multi-rope friction and lifting system, which are established, the new concept of wellbore resistance coefficient is introduced. On the basis of these two basic formulas, a new one Simple coefficient correction. Static and dynamic anti-skid calibration are related to static tension ratio, and can be carried out by means of a table.
