Abstract

The invention provides an anchor cable secondary protective device. The anchor cable secondary protective device comprises a sleeve, a cushion, connecting iron wires and binding iron wires. The anchorcable secondary protective device is fixed to the lower end of an anchor cable in a roadway, and an anchor net is fixed to the surface of the roadway; a metal pad and an anchor are installed on the anchor cable extending out of the roadway in sequence; the lower end of the anchor cable is installed in the sleeve, and the cushion is installed between the anchor cable and the sleeve; one ends of the connecting iron wires penetrate through the bottom end of the sleeve, and two ends of the connecting iron wires are fixed to the anchor net; and the binding iron wires are fixed on the two connecting iron wires above the sleeve. The anchor cable secondary protective device fundamentally solves the problem of anchor cable hurting people.

Description

technical field [0001] The invention relates to a secondary protection device for anchor cables, which is mainly used for roadways supported by anchor cables, and is used to prevent the tension end anchors and backing plates from falling and hitting people caused by the breakage of anchor cables, and the steel strands at the anchor cable head to break wires. It has a targeted protective effect in case of hurting people or scratching people with the head of the anchor cable. Background technique [0002] In order to improve the efficiency of tunneling in coal mine tunneling projects, most of them adopt the anchor net cable support method. The anchor cable is composed of four parts: prestressed steel strand, backing plate, anchor (clamp), and anchoring agent. Ground stress, structural stress, impact of mining, uneven distribution of stress in the surrounding rock of the roadway, local stress is relatively concentrated, sometimes the anchor cable steel strand is broken, the wir...
