Abstract
The utility model relates to a continuous glass fibre reinforced thermoplastic plastics anchor rod, which is used for the support of a well under a coal mine. The utility model comprising a rod body, an anchor head and an anchor tail mainly solves the disadvantages of a glass fibre reinforced anchor rod having long forming time, heavy weight and high cost. The utility model has the technical proposal that the rod body is made of reinforced material combined by continuous glass fiber and thermoplastic plastics extruded by an extruding machine. In addition, the anchor head is made of injecting plastics, and the anchor tail is made of a metal tube with threads. Therefore, the utility model has the characteristics of light weight, low cost and high productive efficiency as well as the characteristics of the glass fibre reinforced anchor rod having safety, corrosion resistance, cutting performance, high axial tensile strength, high anchoring force and favorable supporting effect.
Description
Technical field
The utility model relate to a kind ofly be used under the coal mine, coal road two is helped and the work plane open-off cut uses a kind of supporting product, a kind of novel anchor rod of more specifically saying so, the body of rod is a continuous glass fibre reinforced thermoplastics bar, and the glass fiber in the bar is axially evenly distribution.
Background technology
Anchor pole is widely-used under coal mine, and the use meeting of anchor metal brings injury to coal-winning machine, and easily causes spark and gas explosion, and is very dangerous, and " glass fibre reinforced plastics rockbolts " product has been arranged again thereafter, and its patent No. is 99216920.8.Though that it has is safe and reliable, corrosion-resistant, can cut, advantage easy for installation, that supporting effect is good in reality is produced in batches and used, is also owed the deficiency that molding time is long, operation is more, production efficiency is low, weight is heavier, cost is high, improves waiting.
Summary of the invention
The purpose of this utility model is to design that a kind of molding time is short, technology is simple, production efficiency is high, in light weight, anchor pole that cost is low, to overcome the deficiencies in the prior art.
The purpose of this utility model is achieved in that
A kind of continuous glass fibre reinforced thermoplastics anchor pole comprises the body of rod, it is characterized in that the body of rod is provided with right-handed thread.The body of rod is a continuous glass fibre reinforced thermoplastics bar, and the glass fiber in the bar is axially evenly distribution.One termination pressure injection of the body of rod has anchor head, and the anchor head periphery is provided with right-handed thread.Another termination of the body of rod is bonded with the anchor tail.The anchor tail is to use metal tube, peripheral machining screw.The anchor tail is to use metal tube, and the one end welds a bolt.The middle part pressure injection of the body of rod has round platform.At least be provided with key shape projection on the round platform one.
This continuous glass fibre reinforced thermoplastics bar, it is a kind of known technology that is different from the bar manufacture method that is commonly called as glass fiber reinforced plastic, it is thermoplastic such as PP, the PA that is extruded by continuous glass fibre and extruder, pass through compound and reinforcing material that get, this bar has lower than glass fiber reinforced plastic bar cost of production, and lightweight characteristics are because continuous glass fibre reinforced thermoplastics bar is that mechanization is produced continuously, and molding cycle is short, so the production efficiency height.
The utility model compared with prior art, molding time is short, technology is simple, technology maturation, the production efficiency height, per minute is produced bar 5～8m, weight approximately reduces by 30%, cost approximately reduces by 40%.
