The invention discloses a retaining structure for a standard knot of a construction hoist. The retaining structure comprises a fastening section clamped on a bolt head and a nut at the same time, and the fastening section does not rotate relative to the bolt head and the nut. One end of the fastening section is connected with a rotation resisting section which is detachably arranged on the standard knot and can prevent the fastening section from freely rotating. The fastening section of the retaining structure is matched with the bolt head and the nut, the fastening section is clamped on the bolt head and the nut at the same time, and the rotation resisting section of the retaining structure is detachably connected to the standard knot. Through the cooperation of the fastening section and the rotation resisting section, the bolt head and the nut can be prevented from freely rotating under the action of vibration, impact or variable load.
本发明公开了一种施工升降机标准节用止退结构,包括同时卡设在螺栓头部和螺母上的紧固段,所述紧固段与螺栓头部和螺母之间均不发生相对转动,所述紧固段一端连接有可拆卸的设置在标准节上的且能够阻止紧固段自由转动的阻转段;本发明中止退结构的紧固段与螺栓头部和螺母均相适配,且紧固段同时卡设在螺栓头部和螺母上,止退结构的阻转段可拆卸的连接在标准节上,通过紧固段和阻转段的配合,能够避免螺栓头部和螺母在受到振动、冲击或变载荷作用下发生自由转动。
