The invention discloses a single-handle towing anchor which comprises an anchor handle and an anchor fluke. The anchor handle is a single-piece configuration pull rod in which an anchor eye is reserved; the anchor fluke comprises an external panel structure and a framework arranged in the panel structure. Compared with an existing double-anchor-handle structure, the anchor body penetration resistance caused by the soil plug effect can be avoided, then the anchor body penetration depth is increased, and the bearing capacity is improved. Meanwhile, in consideration of improvement of the bearing capacity of the anchor body, the anchor fluke structure is improved, an external panel structure and a framework structure arranged in the panel structure are adopted, and under the condition that the using amount of steel is minimum, the huge drag force of the anchor chain and the passive earth pressure on the upper surface of the anchor fluke are transmitted, the stress level of the anchor fluke is reduced, and the structural strength and rigidity of the anchor fluke are improved.
本发明公开了一种单柄拖曳锚,包括锚柄和锚爪;所述锚柄为预留有锚眼的单片构形拉杆;所述锚爪包括外部面板结构和设置在面板结构内部的骨架。本发明相较于现有双锚柄结构,能够避免土塞效应导致的锚体贯入阻力,进而增加锚体贯入深度,承载力提高。同时,考虑到锚体承载力提高,本发明对锚爪结构进行改进,采用外部面板结构和设置在面板结构内部的骨架结构,在钢材用量最省的情况下,传递锚链巨大拖曳力和锚爪上表面被动土压力,降低锚爪应力水平,提高锚爪结构强度和刚度。
