The expansion shell anchor head with the large expansion size comprises an expansion shell inner wedge with the hollow interior and two expansion shell pieces capable of sliding along the expansion shell inner wedge, inclined faces inclining towards a connecting part from the workbench are symmetrically arranged on the two sides of the workbench, and sliding grooves are formed in the two inclined faces respectively. The two sliding grooves penetrate through the axis of the working part and are arranged in a central symmetry mode. The expansion shell piece is provided with a sliding block in sliding fit with the sliding groove. The invention further discloses an anchor rod comprising the expansion shell anchor head with the large expansion size, the anchor rod comprises an anchor rod body, and the expansion shell anchor head is connected with the end of the anchor rod body. According to the anchor head, the maximum expansion size of the expansion shell piece can reach three times of the diameter of the anchor head, the defects that the expansion size of the expansion shell piece is small, the anchoring effect is poor and even supporting cannot be formed are overcome, and due to the excellent expansion size of the expansion shell piece and the large allowance after the anchor head is expanded, the size of the anchor head can be reduced, and an anchor rod and the anchor head can enter an anchor hole conveniently.
本发明公开了一种胀开尺寸大的胀壳锚头，包括内部中空的胀壳内楔和两个可沿胀壳内楔滑动的胀壳片，所述工作台的两侧对称设有由工作台朝向连接部倾斜的倾斜面，两个所述倾斜面上分别设有滑动槽，两个所述滑动槽穿过工作部的轴线呈中心对称设置；所述胀壳片上设有与所述滑动槽滑动配合的滑块。本发明还公开了一种包含胀开尺寸大的胀壳锚头的锚杆，包括锚杆本体，所述胀壳锚头与所述锚杆本体端部相连接。本发明的锚头其胀壳片最大胀开尺寸可达锚头直径的三倍，避免了胀壳片胀开尺寸小锚固效果不好甚至不能形成支护的不足，且由于胀壳片优异的张开尺寸，锚头张开后的余量大，因此可将锚头尺寸缩小，方便锚杆、锚头进入锚孔。
