The invention belongs to the technical field of engineering construction, and provides a safe lifting system for a large-gradient inclined shaft material conveying trolley. Comprising a lifting mechanism, a braking mechanism and a material transporting trolley, the lifting mechanism is connected with the material transporting trolley through a lifting steel wire rope, a falling protector is arranged on the material transporting trolley, and the braking mechanism is movably connected with the falling protector through a braking rope. According to the safe lifting system for the large-gradient inclined shaft material transporting trolley, when the lifting steel wire rope is accidentally broken, the falling protector arranged on the trolley can automatically catch the brake rope, provides pulling force for the brake rope and prevents the trolley from falling, the structure is simple, reliability is high, and the safety is high. And the operation safety of a large-gradient inclined shaft lifting system in water conservancy and hydropower engineering is greatly improved.

    本发明属于工程施工技术领域,提供了一种大坡度斜井运料小车安全提升系统。包括提升机构、制动机构和运料小车,所述提升机构通过提升钢丝绳与所述运料小车连接,所述运料小车上设置有防坠器,所述制动机构通过制动绳与所述防坠器活动连接。本申请提供的大坡度斜井运料小车安全提升系统,当提升钢丝绳发生意外断绳时,设置在小车上的防坠器可自动抓捕制动绳,为制动绳提供拉力,防止小车坠落,结构简单,可靠性强,大大提高了水利水电工程中大坡度斜井提升系统运行的安全性。
