国外井下打捞工具的发展特点是 :(1 )打捞公锥、母锥仍在生产 ;(2 )重视打捞工具配套使用 ;(3 )工具结构各具特点 ,材料质量过关 ;(4 )继续开发组合式打捞工具。主要发展趋势是 :(1 )向一机多能方向发展 ;(2 )开发液压技术 ,消除机械操作缺点 ;(3 )开发辅助打捞工具 ,提高井下事故处理能力。国内在井下打捞工具研制方面与国外相比存在较大差距 ,应借鉴国外先进的管理模式 ,开展跨行业厂际间技术合作 ,制造质量上乘的产品。
The development characteristics of overseas salvage tools are: (1) salvage male cone, female cone is still in production; (2) attach importance to the use of salvage tools; (3) tool structure has its own characteristics, material quality clearance; (4) Salvage tools. The main development trends are as follows: (1) To develop a multi-functional machine; (2) to develop hydraulic technology to eliminate the shortcomings of mechanical operation; and (3) to develop auxiliary salvage tools to improve underground accident handling capacity. Domestic salvage tools in the underground development there is a big gap compared with foreign countries should learn from advanced foreign management mode, carry out cross-industry technical cooperation between plants, manufacturing high quality products.
