Abstract
The utility model discloses an anchor cable which is provided with a pressure yielding device, which belongs to a mine supporting device. In order to overcome the phenomenon that a steel strand of an anchor cable are often broken under the function of strong external force, the utility model comprises a steel strand, a tray and a tightening female screw, wherein a pressure yielding device is arranged on the steel strand which is arranged between the tray and the tightening female screw, the pressure yielding device is a pipe-shaped structure whose configuration is a single section or multi section arc-shaped structure, otherwise, the pressure yielding device can be designed to a spring structure. When rock body or coal bed is distorted, strong external force will be generated, the pressure yielding device begins to distort and yield pressure before the steel strand achieves a yielding limit, and the overload of the steel strand of the anchor cable can not be caused. The utility model has a protecting function on the steel strand which can not be broken, and thereby the service life of an anchor cable is prolonged. The utility model is widely applied to a mine, in particular to a coal mine.
Description
Technical field:
The utility model relates to a kind of mine support device, and especially a kind of being provided with allows the anchor cable of depressor.
Background technology:
The mine especially anchor cable in the coal mine support device comprises steel strand, pallet and clamp nut, during use, hole on rock stratum or coal seam earlier, the hole is built-in goes into resin, and steel strand stir after inserting resin, treat hardening of resin, by clamp nut pallet is fixed on rock stratum or the coal seam, its effect is fixedly rock stratum or coal seam, prevents rock stratum or coal seam slump.Its shortcoming is: the powerful external force that will produce after rock stratum or coal seam deform, and under powerful external force effect, the anchor cable steel strand can produce stretching, when reaching yield point, disrumpent feelings phenomenon often taking place, cause rock stratum or coal seam slump, brings very big harm to the colliery safety in production.
Summary of the invention:
The purpose of this utility model provides a kind of being provided with and allows the anchor cable of depressor, and the depressor that allows wherein can allow pressure, thereby can protect steel strand, overcomes the disrumpent feelings phenomenon of the anchor cable that exists in the above-mentioned background technology.
The purpose of this utility model realizes as follows: comprise steel strand, pallet and clamp nut on the steel strand between pallet and the clamp nut, are provided with and allow depressor.
Allow the depressor be tubular structure, profile is single-unit or more piece arc structure.
In addition, allow depressor can make spring structure.
Effect of the present utility model is: after rock mass or coal seam deform; with the powerful external force effect that produces; before steel strand reach yield point; allow depressor begin distortion and allow pressure; can not cause anchor cable steel strand overload; steel strand are played a protective role, disrumpent feelings phenomenon can not take place, thereby prolong anchor cable application life.
