一种铝合金芯铝绞线内衬管大钢锚型耐张线夹
摘要：
本发明提供一种铝合金芯铝绞线内衬管大钢锚型耐张线夹，该耐张线夹包括沿同一轴线方向设置的大钢锚和铝管，铝合金芯铝绞线设置在铝管中，其改进之处在于，大钢锚的一端为椭圆形圆环，另一端沿其轴线方向设有孔，中间外侧设有螺纹；铝合金芯铝绞线的铝合金芯设置在孔中，铝合金芯和所述孔之间设有铝衬管。和现有技术比，本发明提供的铝合金芯铝绞线内衬管大钢锚型耐张线夹将导线的铝合金芯设置在大钢锚内部并通过液压式压接，极大提高大钢锚对导线握持的有效、稳定；采用液压式压接，工艺成熟，压接质量容易得到保障，克服了铝合金芯铝绞线的压接问题。
摘要（英）：

The invention provides a large steel anchor type strain clamp of an aluminum-alloy-cored aluminum strand liner tube. The strain clamp comprises a large steel anchor and an aluminum tube, wherein the large steel anchor and the aluminum tube are arranged in the coaxial direction, and an aluminum-alloy-cored aluminum strand is arranged in the aluminum tube. The strain clamp is characterized in that one end of the large steel anchor is an oval ring, the other end of the large steel anchor is provided with a hole in the axial direction, the outer side of the middle of the large steel anchor is provided with a thread, an aluminum alloy core of the aluminum-alloy-cored aluminum strand is arranged in the hole, and the aluminum liner tube is disposed between the aluminum alloy core and the hole. Compared with the prior art, the large steel anchor type strain clamp of the aluminum-alloy-cored aluminum strand liner tube enables the aluminum alloy core of a wire to be arranged in the large steel anchor and is connected with the large steel anchor in a hydraulic and pressed mode, and the wire can be effectively and stably held through the large steel anchor. By means of the hydraulic and pressed connection, the process is mature, pressed connection quality is easy to guarantee, and the pressed connection problem of the aluminum-alloy-cored aluminum strand is solved.
