Embodiment Construction
[0024] The production requirements of resin anchoring agent are as follows:
[0025] (1) The diameter and single length of the resin anchoring agent are determined according to the diameter of the anchor rod, the diameter of the drilling hole and the anchoring length. Folded for storage during the process, unfolded for use, see figure 1 ;
[0026] (2) One end of the resin anchoring agent installation tool is a tubular structure, the inner diameter of the pipe is larger than the diameter of the resin anchoring agent, the outer diameter of the pipe is smaller than the inner diameter of the bolt hole, and the length of the pipe body is longer than the length of the anchor rod. The material of the pipe body can be made of plastic and other materials. The other end of the agent installation tool is a threaded connector, the dimensions of which are exactly the same as those of the trolley shank, see figure 2 ;
[0027] (3) The resin anchor installation connector is a tubular str...

The invention relates to a mechanized method for installing a resin anchor rod, belonging to the supporting field of roads and tunnels. The mechanized method is characterized in that the resin anchoring agent adopts the sausage-type tandem packing; the installation of the resin anchoring agent is completed by an installing tool of the resin anchoring agent arranged on a trolley rock-drilling machine; the installation of the resin anchor rod is completed by an installing connector of the resin anchor rod arranged on the other large arm of a trolley; in the process that the resin anchor rod is fed into the bottom of an anchor rod hole, the trolley rock-drilling machine rotates to drive the connector of the resin anchor rod and the resin anchor rod to rotate, and the resin anchor agent is uniformly stirred; then, the trolley stops rotating, the resin anchor agent is solidified, and the rod body of the anchor rod is fixed in the hole; a trolley rotating mechanism rotates continuously, a connecting pin of the resin anchor rod is cut through, and an anchor nut is rotated continuously to compress an anchor supporting plate to the rock cliff. The method not only can ensure the safety of the installation personnel of the anchor rod, but also can improve the working efficiency of the installation of the resin anchor rod greatly.
Description
technical field [0001] The invention belongs to the field of roadway and tunnel support, and can be applied to projects such as underground mine roadways, highway and railway traffic tunnels, water conservancy and hydropower tunnels, etc., and a rock drilling jumbo is used to mechanize the installation of resin anchor rods. Background technique [0002] Bolt support has obvious advantages: it can significantly improve the support effect, reduce the support cost, reduce the labor intensity of workers, improve the working environment, ensure safe production, and facilitate the rapid advancement of the tunneling face. Therefore, bolt support and bolt combined with shotcrete, steel mesh and other means of support have become the most commonly used support methods for underground mine roadways, highway and railway tunnels, and water conservancy and hydropower culverts at home and abroad. [0003] Domestic mine resin bolts are all constructed with pneumatic mixers, coal electric d...
