The invention relates to the technical field of concrete pole hoisting equipment, in particular to a concrete pole hoisting anti-tripping device which comprises a fixed mechanism and a movable mechanism. The fixing mechanism comprises a fixed part fixed on a concrete pole and a movable part in sliding connection with the concrete pole; the movable part is arranged between the fixed plate and the lantern ring on the fixed part; the movable part is connected with the movable mechanism through a pull rope; the movable mechanism is slidably connected with the concrete pole. According to a traditional clamping device for the concrete pole, no matter how tight the concrete pole is clamped, the friction force of the traditional clamping device relative to the concrete pole is fixed, through the design of the lantern ring and the lantern teeth, when the risk that the concrete pole falls off occurs, the fixing mechanism only clamps the concrete pole more and more tightly, and safety is high. According to the cement pole hoisting anti-tripping device, in the pole erecting process, the position of the movable mechanism is continuously adjusted, the stress influence in the pole body is reduced, and the cement pole is protected.
本申请涉及水泥杆吊装设备技术领域,尤其涉及一种水泥杆吊装防脱扣装置,包括固定机构和活动机构;固定机构包括用于固定在水泥杆上的固定部和与水泥杆滑动连接的活动部;活动部设于固定板和固定部上的套环之间;活动部通过拉绳与活动机构连接;活动机构与水泥杆滑动连接。传统的水泥杆的夹紧装置,无论夹的多紧,其相对于水泥杆的摩擦力是固定的,本申请中通过套环和套齿的设计,使得当出现水泥杆脱落的危险的时候,固定机构对水泥杆只会越夹越紧,安全性高。本申请的水泥杆吊装防脱扣装置,通过在立杆过程中,对活动机构位置不断调整,降低了杆体内部的应力影响,保护水泥杆。
