Self-locking type anti-pulling anchor rod
The self-locking type anti-pulling anchor rod comprises an anchor rod body used for drilling and an inserting plate used for bottom locking, feeding threads are evenly formed on the outer circle face of the anchor rod body, a pointed end is fixedly installed at the bottom of the anchor rod body, a locking screw rod is axially arranged in the anchor rod body, an adjusting block is connected to the locking screw rod through threads, and the adjusting block is located on the bottom side in the anchor rod body. Three connecting rods are evenly arranged on the outer circle face of the adjusting block, inserting plates are connected to the outer sides of the connecting rods through pin shafts, guiding openings are formed between the inserting plates and the anchor rod, guiding blocks are arranged at the opening positions of the bottoms of the guiding openings, and extrusion grooves with the rotating direction opposite to that of the feeding threads are formed in one sides of the guiding openings. The extrusion groove is the groove with the rotating direction opposite to that of the feeding thread, so that when the extrusion groove extrudes the insertion plate, the insertion plate can form a rotating direction structure opposite to that of the feeding thread, the insertion plate is promoted to be matched with the anchor rod to form a reverse spiral structure, meanwhile, the insertion plate is matched with the feeding thread and two groups of structures with opposite rotating directions, and the stability of the anchor rod is ensured.
本发明公开了一种自锁型抗拔锚杆，包括用于钻进的锚杆和用于底部锁紧的插板，锚杆外圆面上均匀成型有进给螺纹锚杆底部固定安装有尖头，锚杆内部轴向设置有锁紧螺杆，锁紧螺杆上通过螺纹连接有调节块，调节块位于锚杆内部底侧，调节块外圆面上均匀设置有三个连接杆，连接杆外侧通过销轴连接有插板，插板和锚杆之间成型有引导口，引导口底部开口位置设置有引导块，引导口一侧设置有旋向与进给螺纹相反的挤压槽。本发明挤压槽为与进给螺纹旋向相反的槽，故而当挤压槽挤压插板时，插板能够形成与进给螺纹相反的旋向结构，促使插板配合锚杆形成反向螺旋结构，同时配合进给螺纹，两组相反旋向的结构，保证锚杆的稳定性。
