5000米绳索取心绞车设计

Design of 5000m wireline coring winch

摘要:

在深孔地质岩心钻探中，绳索取心钻进技术对于提高钻探质量和生产效率有极大的优势。在绳索取心钻进中，绳索取心绞车是地质钻探装备中的主要设备，近半个世纪以来，随着绳索取心技术的发展、成熟和广泛应用，取心绞车系统更加安全可靠。本文通过分析国内外现有绳索取心绞车的优缺点，提出了5000 m绳索取心绞车设计方案，设计绞车为分体式结构，由交流变频柜和绞车主体两大部分组成。计算了5000 m绳索取心绞车设计的关键技术参数，绞车总功率为60 kW，配套12 mm钢丝绳，最大可提供50 kN的提升力，光毂提升速度最快可达60 m/min。针对绳索取心绞车提升过程中滚筒钢丝绳常见的垒绳、压绳、咬绳等问题，设计了双折线绳槽。

Abstract:

In deep-hole geological core drilling, wireline core drilling technology has great advantages for improving drilling quality and production efficiency. In wireline core drilling, the winch is the main part of the geological drilling equipment. With the development, maturity and wide application of wireline coring technology over nearly half a century, the wireline winch system has become more safe and reliable. Through analysis of the advantages and disadvantages of the wireline coring winches at home and abroad, this paper proposes a design scheme for the 5000m rope coring winch, which adopts a split structure and consists of two parts: the AC inverter cabinet and the winch itself. The key technical parameters of the design of the 5000m wire coring winch are calculated with the results as: the total power of the winch 60kW, maximum lifting force of the matching 12mm steel wire rope 50kN, and the fastest lifting speed of the light hub 60m/min. Aiming at the work conditions such as overlapping, cross cutting, and biting of lines, which are common during the lifting process of the rope core winch, the double fold grooves are designed.
