为了完善绳索取心钻进技术，我们在φ42毫米钻杆斜脱式提引器的基础上，吸收兄弟单位的经验，设计试制了φ56毫米绳索取心钻具斜脱式提引器（见附图）。提钻时在钻杆上端部拧上提引接头（俗称蘑菇头），将托盘缺口推入钻杆并提升提引器，托盘顶住提引接头环状的突出部分，把钻杆提起。松绳后提引器下落，档板抵住提引接头，使它自动斜脱，下钻时除了将钻杆置于托盘缺口外，还要把滚轮轴推入托盘一端的槽内（槽的外端有一圆窝，保证滚轮轴不会自动离槽），提引器沿钻杆上升，直到托盘拉起钻杆，提引器下钻到孔口，将滚轮轴提拉出槽子，提引器便可推离钻杆。如此循环往复。
In order to improve the cord coring drilling technology, based on the experience of our brother units, we have designed and manufactured a φ56 mm cord coring drill with a bevel lift device (see attached Figure). When drilling, screw up the upper joint of the drill pipe (commonly known as the mushroom head), push the tray notch into the drill pipe and lift the lifting device. The tray abuts against the protruding part of the lifting joint to lift the drill pipe. After the slack rope lift the indexer to fall, the baffle stops to lift the joint, making it run off automatically. Besides placing the drill pipe in the tray gap while drilling, push the roller shaft into the groove at one end of the tray The outer end of a round nest to ensure that the roller shaft will not automatically leave the slot), lifting device along the drill pipe rise, until the tray pull the drill pipe, lifting device under the drill to the orifice, the roller shaft pulled out of the trough to mention The device can be pushed away from the drill pipe. This cycle of reciprocation.
