Pin type mechanical connector and precast concrete pile
The invention discloses a pin type mechanical connector and a precast concrete pile. The mechanical connector comprises a first nut sleeve, a second nut sleeve, an insertion rod and a locking positioning pin. The first nut sleeve is connected with the insertion rod; a positioning pin blind hole with gradually reduced aperture is formed in the insertion rod; a locking positioning pin is arranged on the second nut sleeve, and after the inserting rod is inserted into the second nut sleeve, the locking positioning pin is clamped with the inserting rod and used for limiting and fixing the inserting rod and the second nut sleeve. According to the pin type mechanical connector disclosed by the invention, a locking structure is formed between the locking positioning pin and the second sleeve nut after the locking positioning pin is clamped with the insertion rod, so that any axial movement cannot be carried out between the positioning insertion rod and the second nut sleeve, that is, when precast concrete is connected through the anchor clamping type mechanical connector disclosed by the invention, the locking positioning pin can be locked; and it can be guaranteed that the connecting end faces of the two sections of precast piles are completely attached without gaps.
本发明公开了一种销钉式机械接头和预制混凝土桩，其中机械接头包括包括第一螺母套筒、第二螺母套筒、插杆以及锁紧定位销；第一螺母套筒与插杆连接；插杆上设有孔径逐渐缩小定位销盲孔；第二螺母套筒上设有锁紧定位销，当插杆插入第二螺母套筒中后，锁紧定位销与插杆卡合，用于将插杆与第二螺母套筒进行限位固定。本发明公开的销钉式机械接头在锁紧定位销与插杆卡接后锁紧定位销与第二套筒螺母之间形成锁死结构，使得定位插杆与第二螺母套筒之间无法进行任何轴向运动，即通过本发明公开的锚卡式机械接头进行预制混凝土连接时，能够保证两节预制桩连接端面之间完全贴合无间隙。
