Description
技术领域
本发明涉及机械采油技术领域，具体来说是一种适用于超长冲程抽油机的柔性绳。
背景技术
超长冲程抽油机是一种新型举升方式，非常适用于低产低效井，然而关键部件柔性绳易磨损、钢丝绳抗拉强度差等问题，轻则出现导致井口漏油污染环境，重则拉断导致地面及井下设备损坏，严重影响超长冲程抽油机的使用寿命。现有专利柔性钢丝绳，在内层钢丝绳和外层钢丝绳之间填充聚乙烯，然而该柔性钢丝绳易与盘根盒及天车轮发生刚性磨损，导致钢丝断丝、抗拉强度差，造成超长冲程抽油机使用寿命低。
发明内容
本发明的目的在于提供耐磨性好、抗拉强度高及使用寿命长的一种适用于超长冲程抽油机的柔性绳。
为了实现上述目的，本发明采用如下技术方案：它由绳芯、胶粘固化层和涂塑层组成；通过胶粘固化层将绳芯和涂塑层胶结为一体；绳芯是由不锈钢钢丝绳和弹性纤维材料组成，绳芯内部由多股不锈钢钢丝绳以瓦林吞式排列，不锈钢钢丝绳之间空隙填充弹性纤维材料；涂塑层是由外部强化钢丝绳和涂塑材料组成，涂塑材料加热与外部强化钢丝绳固化后融为一体结构。
所述的涂塑层为复合高分子耐磨性材料，外部强化钢丝绳为镀锌钢丝绳。
所述柔性绳外径为24mm~32mm。
本发明与已有技术相比具有如下优点：
1）本发明涂塑层材料为复合高分子耐磨性材料耐老化、耐磨损、耐腐蚀性能突出。
2）本发明通过绳芯内部填充弹性纤维材料，极大地增加了柔性绳的柔韧性，弯曲性能得到极大增强。
3）本发明听过胶粘固化层将绳芯和涂塑层胶结为一体结构，粘合度高，不易脱胶。
附图说明：图1为本发明柔性绳横截面图；图2为绳芯1的截面图；图3为涂塑层3的截面图；图4为本发明现场安装示意图。
图中：1.绳芯、2. 胶粘固化层、3. 涂塑层、4. 不锈钢钢丝绳、5. 弹性纤维材料、6. 外部强化钢丝绳、7.涂塑材料。
具体实施方式：以下结合附图对本发明作进一步详述，本发明由绳芯1、胶粘固化层2和涂塑层3组成；通过胶粘固化层2将绳芯1和涂塑层3胶结为一体；绳芯1是由不锈钢钢丝绳4和弹性纤维材料5组成，绳芯内部由多股不锈钢钢丝绳4以瓦林吞式排列，不锈钢钢丝绳4之间空隙填充弹性纤维材料5；涂塑层3是由外部强化钢丝绳6和涂塑材料7组成，涂塑材料7加热与外部强化钢丝绳6固化后融为一体结构。
所述的涂塑层3为复合高分子耐磨性，外部强化钢丝绳6为镀锌钢丝绳。
所述柔性绳外径为24mm~32mm。
现场应用时将本发明的一端与超长冲程抽油机的滚筒连接，另一端通过天车轮至井口，最后连接井下抽油杆，实现滚筒转动带动柔性绳及井下抽油泵往复运动实现井液的举升，本发明耐磨性好、抗拉强度高、涂塑层不脱胶，能够有效延长超长冲程抽油机使用寿命。
