Steel ball self-locking mechanical connecting device and connecting method
The invention discloses a steel ball self-locking mechanical connecting device and method, and belongs to the technical field of buildings. The steel ball self-locking mechanical connecting device comprises an upper joint and a lower joint, and further comprises steel balls, a supporting ring, a limiting piece, a supporting piece, a plug and an arc-shaped groove, wherein the steel balls are arranged in the upper joint; the steel balls are arranged in the circumferential direction of the outer side face of the supporting ring; the limiting piece is used for limiting the downward falling trend of the supporting ring; the supporting piece is used for providing downward and centripetal force for the steel balls; one end of the plug is connected with the upper end in the lower joint, and the other end of the plug extends out of the upper end of the lower joint; the arc-shaped groove is of a groove structure formed in the side wall of the extending end of the plug in the circumferential direction; and after the upper joint and the lower joint abut against each other, the plug penetrates through the limiting piece and jacks up the supporting ring, and the steel balls enter the arc-shapedgroove under the acting force of the supporting piece. The device is easy to assemble, structures are matched with each other after assembly, automatic triggering and locking can be achieved after theupper joint and the lower joint abut against each other under the action of gravity, triggering is easy and convenient, rigid limitation is formed between the steel balls and the rigid plug arc-shaped groove after triggering, and stable and effective anti-drawing acting force is provided for a precast pile after connection.
本发明公开了一种钢球自锁机械连接装置及连接方法，属于建筑技术领域。装置包括上接头和下接头；还包括钢球，其置于上接头中；托环，钢球沿托环外侧面周向布置；限位件，其限制托环向下掉落的趋势；支撑件，对钢球提供向下和向心的力；以及插头，其一端与下接头内部上端连接，另一端从下接头上端伸出；弧形凹槽，其为周向开设在插头伸出端侧壁的凹槽结构；上下接头抵接后，插头穿过限位件并顶起托环，钢球在支撑件的作用力下进入弧形凹槽中。本发明装配简单，装配后结构间相互配合，在重力作用下上下接头抵接后即可自动触发锁定，触发简单方便，触发后钢球与刚性的插头弧形凹槽间形成刚性的限制，为预制桩连接后提供稳定有效的抗拉拔作用力。
