Detailed Description
The utility model is further described below with reference to the figures and examples.
This embodiment quick anchor of driving face protects stock, including cavity stock 1, the hole front end of cavity stock is powder charge chamber 2, is provided with medicament flow department passageway 3 on the chamber wall in powder charge chamber, is provided with anchor agent package 4 in the powder charge chamber, still be provided with the spacer ring subassembly in the cavity stock, the spacer ring subassembly includes elasticity ring body 5 and pastes the barrier film 6 that is used for preventing the anchor agent package and withdraws from on the elasticity ring body, is provided with the breach 7 that is used for adjusting elasticity ring body diameter on the elasticity ring body, is provided with the draw-in groove 8 that is used for fixed elasticity ring body on the interior pore wall of cavity stock.
The quick anchor protection anchor rod of the driving face further comprises a charging push rod 9, the diameter of the charging push rod is smaller than the diameter of an inner hole of the elastic ring body, and an annular flange 10 used for pushing the spacer ring assembly into the hollow anchor rod is arranged at one end of the charging push rod.
The construction process of the rapid anchoring and protecting anchor rod of the driving face of the embodiment is as follows:
1) and pushing the anchoring agent bag into a medicine charging cavity at the front end of the hollow anchor rod by using a medicine charging push rod, and ensuring the integrity of the anchoring agent bag.
2) The annular flange of the charging push rod is used for loading the spacer ring assembly into the hollow anchor rod, so that the elastic snap ring is clamped in the clamping groove in the hollow anchor rod.
3) And (4) placing the hollow anchor rod on a pneumatic anchor rod drilling machine, and then upwards jacking the anchor rod into the anchor rod hole by using the pneumatic anchor rod drilling machine.
4) And inserting the charge push rod into the hollow anchor rod, extruding the anchoring agent bag after the charge push rod passes through the isolating die of the spacer ring assembly, smashing the anchoring agent bag, and extruding the anchoring agent flowing out of the anchoring agent bag from the agent flow passage.
In the rapid anchor protection anchor rod for the driving face, the anchoring agent bag passes through the charge cavity which is pre-installed in the hollow anchor rod, and the spacer ring assembly can prevent the anchoring agent bag from withdrawing from the charge cavity, so that the anchoring agent bag can be stably kept in the charge cavity when the hollow anchor rod is inserted into an anchor rod hole at the top of a roadway; and the anchoring agent bag is inserted into the anchor rod hole together with the hollow anchor rod, so that the anchoring agent bag can reliably reach the bottom of the anchor rod hole.
