The invention relates to a rear reaming anchor rod mounting device capable of measuring wedge lock travel, which belongs to an anchor rod mounting tool. The end surface of one end of a straight rod (5) is provided with a drill rod blind hole (51) which is connected with a drill rod (16), and the end surface of the other end thereof is provided with an anchor rod blind hole (52) which is connected with an exposed end (15) of the anchor rod. A sliding rod seat (53) is fixed on the outer wall of the middle section of the straight rod (5) and is provided with a sliding rod hole (54). A sliding rod (55) penetrates into the sliding rod hole (54), and the axes of the sliding rod (55) and the sliding rod hole (54) are parallel with the axis of the straight rod (5). The invention has the advantages of convenient travel control of the wedge lock of the anchor rod, realized mechanical mounting, visual and controllable mounting quality, convenient operation, simple construction, and quick mounting; in addition, the invention can completely develop the tension strength of the anchor rod, provide the maximum anchoring force and favorable conditions for popularizing and applying rear reaming anchor rods.
Description
technical field [0001] The invention relates to a tool for installing anchor rods, in particular to a rear reaming anchor rod installer capable of measuring the stroke of a wedge lock. It is an auxiliary device for rock or concrete anchor support or structural reinforcement or equipment installation. Background technique [0002] Chinese patent announcement number: CN2404619Y, announcement date: November 8, 2000, the name of the utility model "a concrete self-locking plunger and supporting reaming drill bit", after the launch, because of its novel anchoring mechanism, reliable performance, wide range of applications Widely obtained a large number of applications. Post-reaming bolt technology is to use a reaming drill bit in a straight hole drilled on rock or concrete, expand the bottom of the straight hole into an inverted cone, insert the slotted bolt with a wedge into the bottom of the hole, pressurize the rear wedge The block is pressed into the groove, so that the rod ...
