Abstract

The invention discloses a bolting-grouting joint. The bolting-grouting joint comprises a protective sleeve, a sliding groove and a connecting column; supporting bases are fixed in the protective sleeve; elastic grooves are formed in the supporting bases; springs are embedded in the elastic grooves; one ends of the springs are connected with supporting columns; sliding blocks are fixed on two sidesof the supporting columns; clamping plates are fixed to one ends of the supporting columns; the elastic grooves are formed in one sides of the sliding blocks; a main body is arranged on one sides ofthe clamping plates; a nameplate is arranged on one side of the main body; bolts are connected with the interior of the nameplate; and the surfaces of the bolts are connected with the main body. The bolting-grouting joint is provided with the connecting column which enable threaded column to be in butt joint with the sliding groove, then a nut is in butt joint with the threaded column, the nut isrotated clockwise so the surface of the nut is matched with a positioning groove, the connecting column is installed on the body, and therefore the suitable connecting columns can be installed according to difference in types.

Description

technical field [0001] The invention relates to the technical field of mining equipment, in particular to an anchor injection joint. Background technique [0002] The anchor injection joint is also the anchor stirrer, which connects the anchor drilling rig and the anchor rod, and is used to stir the resin anchoring agent to realize fast installation and tightening of the nut. It is used for mixing and installation of roadway support anchor cables and anchor rods. [0003] The anchor injection joints currently on the market have such shortcomings. When the anchor injection joints are transported, the anchor injection joints are scattered and there is no protection device to protect the anchor injection joints, which causes the anchor injection joints to collide with each other and wear. The service life is reduced, so the current anchor joints should be improved. Contents of the invention [0004] The purpose of the present invention is to provide anchor injection joints ...
