Self-locking mechanical connecting device and connecting method
The invention discloses a self-locking mechanical connecting device and a connecting method, and belongs to the technical field of buildings. The device comprises an upper joint, a lower joint, an inner screw rod, a clamping and locking mechanism and a thrust mechanism, wherein one end of the inner screw rod is in threaded connection with the bottom end of the upper joint, and the other end of theinner screw rod extends out of the upper joint; the clamping and locking mechanism comprises a long rod and a short rod and is inserted into the inner screw rod; a movable block assembling hole is formed in the extending end of the inner screw rod, and a movable block is arranged in the movable block assembling hole in a matched and movable mode; the movable block is inserted into the short rod in a matched mode; the thrust mechanism is arranged in the inner screw rod and provides force away from the central axis of the inner screw rod for the movable block; and the side, close to the inner wall of the lower joint, of the movable block is in contact with the inner wall of the lower joint and then is connected with the inner wall of the lower joint in a matched mode. The device is simple to assemble, the structures are matched with each other after being assembled, the device is stable and cannot be scattered, the false touch probability is small in the using process, triggering is convenient, self-locking can be triggered in the butt joint process of the upper joint and the lower joint, self-locking is completed after the upper joint and the lower joint are in butt joint, and after self-locking is triggered, the anti-pulling effect after precast piles are connected is stable and effective.
本发明公开了一种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；下接头；还包括内螺杆，其一端与上接头底端螺接，另一端从上接头伸出；卡锁机构，其包括长杆和短杆，插接在内螺杆中；内螺杆伸出端开设有活动块装配孔，设有活动块配合活动安装于活动块装配孔中；活动块与短杆配合插接；以及推力机构，其置于内螺杆中，对活动块提供远离内螺杆中轴线的力；活动块靠近下接头内壁一侧与下接头内壁接触后配合连接。本发明装置装配简单，装配后结构间相互配合，稳定不会散落，在使用过程中误触概率小，且触发方便，上下接头对接过程中会触发自锁，并在上下接头对接后完成自锁，触发自锁后，对预制桩连接后的抗拉拔效果稳定有效。
