Abstract
An active-protection support device with anchor rods comprises two main pull rods, an auxiliary pull rod, a U-type shed, a shed locking body and a nut. Both ends of the main pull rods and both ends of the auxiliary pull rod are provided with same first clamping notches and second clamping notches. Main pull rod connecting holes and auxiliary pull rod connecting holes are arranged on both sides of the first clamping notches and the second clamping notches. The second clamping notch at the left end of the auxiliary pull rod is arranged in and coincides with the first clamping notch on the right side of one main pull rod. The second clamping notch at the right end of the auxiliary pull rod is arranged in and coincides with the first clamping notch on the left side of the other main pull rod. The U-type shed is clamped in the first clamping notch and the second clamping notch of the main pull rod and the auxiliary pull rod. The shed locking body is disposed on the outer side of the U-type shed. The active-protection support device with anchor rods is characterized by further comprising a plurality of anchor rods, both sides of the shed locking body are provided with fixing lug wings, anchor rod holes are arranged on the fixing lug wings, one ends of the anchor rods are fixed on a rock face, and the other ends of the anchor rods penetrate through the main pull rod connecting holes and the auxiliary pull rod connecting holes on the main pull rods and the auxiliary pull rod and penetrate through the anchor rod holes on the fixing lug wings on the shed locking body to be fixed through the nut. According to the active-protection support device with anchor rods, passive protection is changed into active protection, local stress compensation can be achieved, and strength of weak spots can be enhanced.
