一种煤壁片帮锚杆辅助锚固装置
摘要：
本实用新型公开了一种煤壁片帮锚杆辅助锚固装置，其包括锚固套和防松块，锚固套为T型结构，所述锚固套的中心通孔为与螺纹锚杆配合的内螺纹孔，所述锚固套的外壁上焊接一体设有楔形的防松块，锚固套的径向上设置有多个注浆连通孔，锚固套与煤壁片帮上的钻孔之间设置有注浆孔，注浆后所述防松块伸入注浆内设置，所述锚杆的外侧设置有锚杆锁帽，所述锚杆锁帽锁紧在锚固套的外侧面上。本实用新型通过设置防松块，可以使得锚固套很好的固定在钻孔内，而且，锚固套的长度可以小于锚杆长度，而在锚固套上设置有注浆连通孔，可以通过注浆将浆液填充在注浆连通孔内，这样，锚固套就会与钻孔内的注浆形成一个整体，实现对煤壁的锚固。
摘要（英）：

The utility model discloses an anchor is assisted to rib wall caving stock, it includes anchor cover and locking piece, the anchor is overlapped for T type structure, the central through hole of anchor cover be with screw thread stock complex internal thread hole, welding an organic whole is equipped with wedge -form locking piece on the outer wall of anchor cover, and the footpath of anchor coverupwards is provided with a plurality of slip casting intercommunicating pores, is provided with the injected hole between the drilling that anchor cover and rib piece were able to help, after the slip casting locking piece sets up in stretching into slip casting, the outside of stock is provided with the stock lock nut, the locking of stock lock nut is on the lateral surface of anchor cover. Theutility model discloses a set up locking piece, can be so that fine the fixing in drilling of anchor cover, in addition, the length of anchor cover can be lighter than the rock -bolt length, and putsin the anchor and be provided with the slip casting intercommunicating pore, can pack the thick liquid in the slip casting intercommunicating pore through slip casting, and like this, the anchor coverwill form a whole with the slip casting in the drilling, and the realization is to the anchor of rib.
