Problems solved by technology
In the practical application of this kind of anchor cable anchor section extrusion machine, the disadvantages exposed are: 1) the diameter of the extruded steel sleeve is small, ≯φ30.0mm; 2) the effective extrusion of the extruded steel sleeve produced Segment length≯400.0mm, generally 150.0mm
The extruded steel sleeve of this size has a weak grip on the processed workpiece, and it is impossible to hold the carbon fiber anchor cable reinforcement that can withstand large tonnage tension.
In addition, the existing carbon fiber anchor cable steel sleeve anchor section extrusion device still has the disadvantages of high production cost, different molds need to be replaced for workpieces with different diameters, troublesome operation, and low processing efficiency.
Therefore, the use effect of the existing carbon fiber anchor cable steel sleeve anchor section extrusion device is still not ideal enough

Embodiment Construction
[0017] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0018] Embodiments of the present invention: a roller-type extrusion device for the compression of the anchorage section of the steel sleeve of the carbon fiber anchor cable according to the present invention, its structural schematic diagram is as follows figure 1 and figure 2 As shown, the device includes a front fixed plate 2 and a rear fixed plate 2.1. During manufacture, the front fixed plate 2 and the rear fixed plate 2.1 are respectively made to pass through the center of the steel sleeve 3 on the processed carbon fiber anchor cable 4. Hole 7; Then between the front fixed disk 2 and the rear fixed disk 2.1, three extruding rollers 1 are arranged, and the extruding roller 1 is made into a conical column shape with a small diameter at the front end and a large diameter at the rear end. The ratio of the diameter of the rear end of the ro...

Abstract
The invention discloses a roller type extrusion device for pressing and fixing an anchorage section of a steel sleeve of a carbon fiber anchor rope. The roller type extrusion device comprises a front fixing disk and a rear fixing disk, wherein three tapered cylindrical extrusion rollers are arranged between the front fixing disk and the rear fixing disk; the diameter of the front end of each extrusion roller is small; the diameter of the rear end of each extrusion roller is large; the three extrusion rollers are fixed on three transmission shafts respectively and are out of contact with one another; the three transmission shafts are parallel to one another; the two ends of the three transmission shafts are arranged on the front fixing disk and the rear fixing disk and distributed according to equilateral triangles; and center holes through which the steel sleeve on the carbon fiber anchor rope to be processed penetrates are formed in the front fixing disk and the rear fixing disk. The roller type extrusion device has the advantages that the roller type extrusion device is high in bond strength, the diameter of a processing workpiece is larger, the processing workpiece is longer, and the roller type extrusion device is low in manufacturing cost, convenient in use and high in processing efficiency due to the fact that the structure is simple, and auxiliary tools such as manufacturing molds are not required.
Description
technical field [0001] The invention relates to a roller-type extrusion device for pressing the anchoring section of a steel sleeve of a carbon fiber anchor cable, and belongs to the technical field of carbon fiber anchor cable manufacturing tools. Background technique [0002] Anchor cable is a device used to strengthen rock mass in geotechnical engineering. It applies tension to the anchor cable with one end fixed to the reinforced rock mass and the other end anchored to the stable rock mass, so that the reinforced rock mass and the stable rock mass Between the bodies, a compressive stress is generated, thereby increasing the anti-sliding force; or an upward component force is generated, thereby reducing the sliding force. To achieve the purpose of strengthening the rock mass. [0003] Carbon fiber is a new material with excellent mechanical properties. Its specific gravity is less than 1 / 4 of steel, and its tensile strength is 7 to 9 times that of steel, generally above ...
