As a tensile member that goes deep into the ground, the anchor rod is connected to the engineering structure at one end, and the other end goes deep into the ground to prevent the slope from slipping. The existing top of the anchor rod has a simple structure to prevent falling off The function is weak; so it is necessary to design a top-opening anti-falling anchor

The invention belongs to the technical field of anchor rods, and particularly relates to an anti-falling anchor rod mechanism. The anti-falling anchor rod mechanism comprises an anchor rod body, a base plate, a slurry stopping plug, a conical anchor head, anti-falling mechanisms, a circular hole, a blade mechanism, a first motion groove, a second motion groove, first narrow grooves and a first circular hole; the non-through circular hole is formed in the end face of the anchor rod body; the first circular hole is formed in the end face of the circular hole; and the first narrow grooves are distributed close to the first circular hole. The first circular hole is formed in the end face of the circular hole to conveniently mount a worm operating rod; the first narrow grooves are formed in theinner circle face of the circular hole to facilitate passing of a fixing plate; the end face of the conical anchor head is mounted on the lower end face of the anchor rod body to facilitate an anchorrod to enter soil; the anti-falling mechanisms are mounted on the outer circle face of the anchor rod body and distributed near the conical anchor head to prevent the anchor rod from falling off fromthe soil; and the blade mechanism has the effect of increasing acting force of the soil on the anchor rod, and thus the anchor rod is not prone to falling off better.
Description
technical field [0001] The invention belongs to the technical field of anchor rods, in particular to an open-top anti-falling anchor rod. Background technique [0002] At present, the existing bolts are mostly used in the roadway support in coal mines. They reinforce the surrounding rocks of the roadway so that the surrounding rocks can support themselves. The existing bolts are not only used in mines, but also used in engineering technology to carry out main body reinforcement to slopes, tunnels and dam bodies. As a tensile member that goes deep into the ground, the anchor rod is connected to the engineering structure at one end, and the other end goes deep into the ground to prevent the slope from slipping. The existing top of the anchor rod has a simple structure to prevent falling off The function is weak; so it is necessary to design a top-open anti-falling anchor. [0003] The present invention designs a top-opening anti-falling anchor rod to solve the above problems...
