Long-range spray pipe filled with resin anchoring agent

Abstract

The invention belongs to the technical field of anchor rod supporting, particularly relates to a long-range spray pipe filled with a resin anchoring agent. The long-range spray pipe solves the problems that the hole entering depth of an existing high-pressure gas spray pipe is uncontrollable, the range is not far enough, and high-pressure airflow enters a drilled hole to disturb the hole wall. Thelong-range spray pipe comprises a telescopic spray pipe and a bent guide pipe, wherein the telescopic spray pipe can stretch forwards and backwards, the telescopic spray pipe is connected with the bent guide pipe through a ring surface sealing device, the depth of the front end of the telescopic spray pipe inserted into the drilled hole is adjustable, exhaust holes are formed in the pipe wall ofthe front end of the telescopic spray pipe, and the inner wall of the telescopic spray pipe is provided with a spiral guide groove forming a spiral curve at a preset angle alpha with the axis of the telescopic spray pipe and used for improving the stability and range of the resin anchoring agent in the spraying direction. According to the long-range spray pipe, the range is farther, the stabilityis better, the spraying success rate is increased, the depth of the telescopic spray pipe inserted into the drill hole is suitable for high-speed spraying occasions or occasions where multiple resin anchoring agents are sprayed through a single hole, and high-pressure airflow is prevented from entering the drilled hole to disturb the hole wall.

Description

technical field [0001] The invention belongs to the technical field of bolt support, and in particular relates to a long-range nozzle filled with a resin anchoring agent. Background technique [0002] With the full promotion of national industry 4.0 and intelligent manufacturing, it is imminent to realize the automation of the whole process of bolting. The support method of semi-fluid resin anchoring agent plus anchor rod is the main support form in my country at present. The current status of the installation of resin anchoring agents for roadway support in China is as follows: 95% of resin anchoring agents are installed manually, and 5% of resin anchoring agents are integrated with anchor rods. When installing the resin anchoring agent alone, the operator must climb the height in the empty roof area, manually take the resin anchoring agent, correct the direction of the resin anchoring agent into the hole, load the resin anchoring agent with one hand, and insert the anchor...
