Abstract
The utility model discloses a cell type steel band, including the steel band body, the left and right sides of steel band body is provided with first stabilizer blade and second stabilizer blade respectively, the circular arc groove has been seted up at the top of steel band body, the elliptical aperture that is located on the circular arc groove has been seted up at the top of steel band body. The utility model can be used for the tunnel support of mine underground tunnel working face cutting holes, chambers and other fields, and has better effect on treating unstable surrounding rocks; a plurality of dispersed anchor rods and anchor cables are connected through the steel belt to form an integral bearing structure, so that the integral effect of anchor rod and anchor cable support is obviously improved, and the application effect in incomplete roof rocks is better; the bending strength and tensile strength of the W steel belt which is widely applied in the market are much higher through the design of the arc-shaped groove, the W steel belt can play a better role in supporting on a mine, and the W steel belt has a wide application range.
Description
Technical Field
The utility model relates to a steel band technical field especially relates to a cell type steel band.
Background
The steel belt is one of key components of a coal roadway anchor rod and anchor cable support system, and has two main functions, namely, a surface protection function, wherein the force applied by the anchor rod and the anchor cable is transmitted to roadway surrounding rock through the steel belt, so that the integrity and the stress state of the surrounding rock are ensured; and secondly, the single anchor rod and anchor cable are connected through the steel belt to form an integral structure, so that the integral supporting effect of the anchor rod and anchor cable is improved, and the steel belt is an indispensable supporting product especially under the geological conditions of complex geological conditions, cracks on a top plate, soft and broken rock strata and the like.
At present, steel strips for mines are mainly flat steel strips and W steel strips, and the W steel strips have more advantages in bending resistance, rigidity and tensile strength than the flat steel strips, but are damaged in practical use, so that steel strips with higher bending resistance and tensile strength than the W steel strips are required.
SUMMERY OF THE UTILITY MODEL
In order to overcome the problem that exists among the correlation technique, the embodiment of the utility model provides a cell type steel band has solved the bending resistance and the general problem of tensile strength of W steel band.
The embodiment of the utility model provides a cell type steel band, including the steel band body, the left and right sides of steel band body is provided with first stabilizer blade and second stabilizer blade respectively, the circular arc groove has been seted up at the top of steel band body, the elliptical aperture that is located on the circular arc groove has been seted up at the top of steel band body.
Further, the arc groove is arranged at the center line of the steel belt body.
Furthermore, the first supporting leg and the second supporting leg are symmetrically arranged by taking the center line of the steel belt body as the center.
The embodiment of the utility model provides a technical scheme has following beneficial effect: the method can be used for cutting holes on the working face of the underground tunnel, supporting the tunnel in a chamber and other fields, and has better effect on treating unstable surrounding rocks; a plurality of dispersed anchor rods and anchor cables are connected through the steel belt to form an integral bearing structure, so that the integral effect of anchor rod and anchor cable support is obviously improved, and the application effect in incomplete roof rocks is better; the bending strength and tensile strength of the W steel belt which is widely applied in the market are much higher through the design of the arc-shaped groove, the W steel belt can play a better role in supporting on a mine, and the W steel belt has a wide application range.
It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the invention as claimed.
