The invention discloses a standard knot hoisting mechanism used for a construction hoist. The standard knot hoisting mechanism comprises a rotating seat and a hoisting assembly arranged on the rotating seat. The rotating seat comprises a seat body, a rotating shaft arranged at the bottom of the seat body and downwards inserted into a hoisting cage and a trigger wheel arranged at the lower end of the rotating shaft in a sleeving manner and capable of eccentrically rotating along with the rotating shaft. An interlocking switch used for controlling on-off of an operation loop of the construction hoist is arranged in the hoisting cage, and the interlocking switch is located on one side of the rotating shaft and located on the same horizontal plane with the trigger wheel. According to the hoisting mechanism, the trigger wheel capable of eccentrically rotating and the interlocking switch are arranged, in the eccentric rotation process of the trigger wheel, the end face, close to the interlocking switch, of the trigger wheel can abut against the interlocking switch or be separated from the interlocking switch, and therefore when the hoisting mechanism works, the trigger wheel can be rotated to the position where the trigger wheel can abut against the interlocking switch, the interlocking switch is triggered at the moment, the construction hoist does not run, and potential safety hazards are avoided.

    本发明公开了一种用于施工升降机的标准节吊装机构,包括旋转座、设于旋转座上的吊装组件,旋转座包括座本体、设于座本体底部且向下插入吊笼中的转轴、套设于转轴下端部且能够随着转轴作偏心转动的触发轮,吊笼内具有用于控制施工升降机的运行回路通断的联锁开关,联锁开关位于转轴一侧且与触发轮位于同一水平面上。本发明的吊装机构,通过设置能够偏心转动的触发轮和联锁开关,在触发轮的偏心转动过程中,触发轮靠近联锁开关的端面分别能够抵触于联锁开关上或脱离联锁开关,使得当吊装机构工作时,可将触发轮转动至能够抵触于联锁开关上的位置,此时联锁开关被触发,施工升降机不会运行避免了安全隐患。
