The invention provides an overload self-unloading anchorage device which comprises an anchor rod provided with a support. The pull rod is provided with a first end and a second end which are oppositely arranged, and the first end and the second end of the pull rod are exposed out of the anchor rod; the resistance spring sleeves the pull rod and is used for connecting the first end of the pull rod and the anchor rod; the anchor flukes are hinged to the second end of the pull rod and hinged to the support through displacement connecting rods. Wherein the pull rod moves relative to the anchor rod along the first end of the pull rod so as to link the anchor fluke to rotate around a hinge point in the direction gradually away from the anchor rod, an anchoring state and an anchoring state are sequentially formed, in the anchoring state, an included angle beta 1 is formed between the anchor rod and the anchor fluke, beta 1 is smaller than or equal to pi/2, and beta 2 is smaller than or equal to pi/2 in the anchoring state. An included angle beta 2 is formed between the anchor rod and the anchor fluke, and beta 2 is larger than pi/2. The technical problem that anchor weighing is difficult due to anchor weighing resistance load generated by extrusion of a traditional anchorage device is solved.
本发明提供了一种过载自卸锚具,包括:锚杆,设有支座;拉杆,具有相对设置的第一端和第二端,所述拉杆的第一端和其第二端显露于所述锚杆外;阻力弹簧,套设于所述拉杆,用于连接所述拉杆的第一端和所述锚杆;若干锚爪,铰接于所述拉杆的第二端,并通过各变位连杆与所述支座铰接;其中,所述拉杆相对所述锚杆沿其第一端运动,以联动所述锚爪绕铰接点向逐渐远离所述锚杆的方向转动,并依次形成锚泊状态和起锚状态,在所述锚泊状态下,所述锚杆与所述锚爪之间形成夹角β1,β1≤π/2,在所述起锚状态下,所述锚杆与所述锚爪之间形成夹角β2,β2>π/2。本发明解决了传统锚具因挤压而产生的起锚阻力荷载导致起锚困难的技术问题。
