Description

大截面导线剥线器 技术领域
本发明涉及一种机械领域；尤其涉及一种大截面导线剥线器。
背景技术
输电是用变压器将发电机发出的电能升压后，再经断路器等控制设备接入输电线路来实现。按结构形式，输电线路分为架空输电线路和电缆线路。架空输电线路由线路杆塔、导线、绝缘子、线路金具、拉线、杆塔基础、接地装置等构成，架设在地面之上。与电缆线路比，架空输电线路建设成本低，施工周期短，易于检修维护。因此，架空线路输电是电力工业发展以来所采用的主要输电方式。
导线承担传导电流的功能，必须具有足够的截面以保持合理的通流密度。为了减小电晕放电引起的电能损耗和电磁干扰，导线还应具有较大的曲率半径。超高压输电线路，由于输送容量大，工作电压高，多采用分裂导线，即用多根导线组成一相导线，一般使用2分裂、3分裂或4分裂导线，特高压输电线路则采用6、8、10或12分裂导线。
剥线器是接续导线对导线进行前期处理的必备工具，一般在接续导线前将钢芯成型铝导线的铝导线剥离，露出钢芯为接续做准备工作。现有技术尽管有针对截面为900mm2和1000mm2的导线的剥线技术，但对于截面为1520mm2的大截面导线剥线的技术尚有诸多不足，这一方面是由于导线本身结构的特殊性，以及导体截面和铝钢比大，另一方面是现有的剥线器结构原因所致。因此需要提供一种大截面面积的剥线器，以满足架空输电线路导线施工工作要求。

在一些实施例中，导向柱5为中部穿过夹具底板6两端抵在夹具顶板8和压板1内侧的中空圆管；夹具顶板8与夹具底板6之间的导向柱5外壁设有压缩弹簧18；导向柱5设有贯穿其中的定位螺栓19，定位螺栓19端部设置定位螺母17。夹具顶板8和夹具底板6上且位于夹线机构进出端两侧分别竖直对应设置铰支座23，铰支座23通过销轴三25与连接杆7连接，连接杆7的相交处设有销轴二24。压板1中部设有螺纹孔，螺纹孔中竖直设置与夹具底板6底部相抵的压紧螺栓16。压紧螺栓16的旋进使夹具底板6和夹具顶板8的距离减小，使连接杆7撬动滚柱9上下移动实现夹紧功能。
通过夹具底板6和夹具顶板8的上下距离调节，使四个滚柱9联动自 动实现对心夹紧的功能，连接杆7的连接节点的距离比例选择实现大距离夹紧的功能。导向柱5实现了夹具底板6和夹具顶板8的定向定位移动。
夹线机构包括：夹线下筒3、夹线上筒4、下压筒30和上压筒31；夹线下筒3和夹线上筒4外壁对应设置环形凸槽，滚柱9设有与环形凸槽相匹配的环形凹槽，夹线下筒3和夹线上筒4内腔设置钢芯铝绞线2；下压筒30和上压筒31通过螺钉32固定设置在夹线下筒3和夹线上筒4的进线端外壁。下压筒30和上压筒31的一端通过销轴一22连接，另一端对应设有通孔，所述通孔中设置活节螺栓34。活节螺栓34一端有蝶形螺母21，另一端设置在位于下压筒30中的销轴四33上。夹线下筒3和夹线上筒4使剥线器具有刀头锯切的导向功能，刀头连接件14防止了刀头15在锯切时的摆动。滚柱9与夹线下筒3夹线上筒4型匹配的凹凸槽，起到了轴向定位的作用，保证了导线锯切表面的平整性。
压下机构包括：支撑板10、外方形筒12、内方形筒13、刀头连接件14和刀头15；支撑板10中心竖直设置螺纹孔，底部竖直设置外方形筒12，螺纹孔中设有压下螺栓26，压下螺栓26上设有限位螺母27，调节限位螺母27的位置可以限定最大压下深度；刀头连接件14为倒置的L形，其顶部竖直设置内方形筒13，侧壁设有竖槽，竖槽中水平设置刀头15，竖槽边侧设有用于防止刀头15摆动的短板。内方形筒13同轴设置在外方形筒12中，其顶部与压下螺栓26相抵，压下螺栓26压下时内方形筒13带动刀头连接件14压下；外方形筒12两侧对应设有分别与支撑板10和刀头连接件14连接的拉伸弹簧29，拉伸弹簧29顶部设置在位于支撑板10底部的开口销28中。
在一些实施例中，夹具连接板11为L形，其底板四角通过螺栓20与夹具顶板8连接，侧板与支撑板10焊接连接；支撑板10与外方形筒12通过焊接连接；刀头连接件14与内方形筒13通过焊接连接；刀头连接件14 与刀头15通过螺栓或焊接连接。
切线时，夹线机构负责夹紧导线，防止锯切时导线的散股。夹线下筒3和夹线上筒4可以根据切线的直径不同做相应选择。夹线筒和压筒通过蝶形螺栓的旋进压紧后，将夹紧机构套入夹线机构，使夹线下筒3和夹线上筒4的环形凸槽插入滚柱9的凹槽，限制夹紧机构的轴向移动。压下机构保证刀具对导线的定心锯切，同时与夹线机构配合，通过限制轴向移动保证锯切截面的平整，夹紧机构可以通过滚柱9在夹线机构上滚动一周，固定在压下机构上的刀具随着锯切一周，即可完成锯切铝线。压下机构与刀头15直接相连，负责刀头15的固定和刀头15的压下定位，刀头连接件14上有短板防止刀具锯切时摆动，外方形筒12和内方形筒13可以保证刀头15上下移动时不偏移和轴心方向的直线运动。
本实施例提供的大截面导线剥线器为一种适用于各种截面面积较大的导线，例如，可用于架空输电线路1520mm2的导线的剥线。
以上所述，仅为本发明的较佳实施例而已，并非用于限定本发明的保护范围。凡按照本发明原理所作的修改，都应当理解为落入本发明的保护范围。
