The invention relates to the technical field of electrically-driven plug pin devices for locking when wings are unfolded and unlocking when the wings are folded, in particular to double-row three-jack plug pin equipment for folding and unfolding the wings, which comprises a first plug pin device, a second plug pin device and a third plug pin device, the first bolt device and the second bolt device are coaxially arranged, and the first bolt device and the third bolt device are not coaxially arranged; each plug pin device comprises a driving assembly, a connecting assembly and an outwards-extending plug shaft. The connecting assembly comprises a first fork lug and a second fork lug which are provided with positioning holes; when the wing is completely unfolded, the center axes of all the positioning holes are aligned to form a taper pin hole; the driving assembly drives the outward-extending insertion shaft to be inserted from the large-diameter end of the taper pin hole to the small-diameter end of the taper pin hole until the outward-extending insertion shaft is locked by extrusion force and friction force; and when the wings need to be folded, the three groups of bolt devices are unlocked at the same time. Through the equipment, the problem that a gap at the joint of the inner section and the outer section of the wing is difficult to eliminate in the prior art can be effectively solved.
本发明涉及机翼展开时锁定、折叠时解锁的电驱动插拔销装置技术领域,特别是涉及一种用于机翼折叠展开的双排三插孔插销设备,包括第一插销装置、第二插销装置和第三插销装置;第一插销装置和第二插销装置同轴设置,第一插销装置和第三插销装置为不同轴设置;插销装置都包括驱动组件、连接组件以及外伸插轴;连接组件包括都设置有定位孔的第一叉耳和第二叉耳;当机翼完全展开时,所有定位孔的中轴对齐,使形成锥销孔;驱动组件带动外伸插轴从锥销孔的大直径一端向锥销孔的小直径一端插入,直至被挤压力和摩擦力锁死;当机翼需要进行折叠时,三组插销装置同时解锁。通过本设备,能有效解决现有技术难以消除连接机翼内段与外段连接处的间隙的问题。
