Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0015] As shown in the figure, the hollow charge anchor device of this embodiment includes a hollow anchor 1, the front end of the inner hole of the hollow anchor is closed, and a tapered one-way sleeve 2 is arranged in the inner hole of the hollow anchor. Between the conical one-way sleeve and the front end of the inner hole of the hollow anchor rod, a charge chamber 3 for placing the drug package is formed. Elastic anti-retraction teeth 22 withdrawn from the drug-charging cavity, and a drug flow channel 4 for the anchoring agent in the drug bag to flow out is provided on the wall of the drug-charging cavity.

[0016] The hollow charge anchor device also includes a charge push rod 5 slidingly fitted with the inner hole of the hollow charge anchor. The charging push rod is used for pushing the drug bag into the drug charging cavity, and for breaking th...

Abstract

The invention discloses a hollow charging anchor rod device. The hollow charging anchor rod device comprises a hollow anchor rod and a charging push rod in sliding fit with an inner hole of the hollowanchor rod, a conical one-way sleeve is arranged in the inner hole of the hollow anchor rod, a charging cavity for containing a cartridge bag is formed between the conical one-way sleeve and the front end of the inner hole of the hollow anchor rod, and the cavity wall of the charging cavity is provided with a medicament flow channel for allowing an anchoring agent in the cartridge bag to flow out. According to the hollow charging anchor rod device, the conical one-way sleeve can prevent the cartridge bag from retreating from the charging cavity so that the cartridge bag can be stably kept inthe charging cavity when the hollow anchor rod is inserted into an anchor rod hole in the top of a roadway, and the cartridge bag is inserted into the anchor rod hole together with the hollow anchor rod so that the cartridge bag can reliably reach the bottom of the anchor rod hole; and the cartridge bag and the hollow anchor rod are simultaneously fed into the anchor rod hole through the anchor rod drilling machine, so that the charging convenience is improved, and the charging safety risk is reduced.

Description

technical field [0001] The invention relates to the field of coal mine roadway support construction devices, in particular to a hollow anchor rod device capable of holding anchoring drug coils. Background technique [0002] The drug coil bolt is the collective name of the anchoring agent and the bolt body. It is used in the tunneling and support of coal mine roadways. In the roadway roof support process of the tunneling face, the pneumatic bolt drill is mainly used for the construction of the bolt hole, and manual filling is used. Anchor medicine roll. At present, manual filling of the bolt coil requires the use of a ladder and an operating platform. Due to the narrow underground roadway and limited operating space, artificial climbing ladders are used to fill the coil, and the operator falls from the ladder and the operating platform and is injured. There are many accident cases and there are great safety hazards. And because the surrounding rock of the roadway is broken ...
