随着地質勘探事业的飞跃发展,鑽探进尺效率得到了空前的提高,在这种新的形势下,如何增加純鑽进时间,解決不导桿鑽进問題,就成为目前急需解决的一个重要问题。通过几个月来的試驗研究工作,我們已經創造出一种简单的主动卡盘。这种卡盘,經多次使用試驗証明,它不仅具有加工方便,操作簡单,容易掌握和解決向上提动、向下加压的問題,而且給今后进一步改进鑽机結构,減輕鑽机迁移时的笨重体力劳动,創造了条件。現在,将这种卡盘的构造、使用方法及操作中的注意事項介紹于下: 一、構造及各部作用这种卡盘(见图)是連接于立軸上之齿瓦筒。內装上下齿瓦各二块,及外部之壺形外套等主要部件所组成。在壺形外套中部按一托盘,並在托盘之两侧,
With the rapid development of geological prospecting, the efficiency of drilling footage has been increased unprecedentedly. Under this new situation, how to increase the pure drilling time and solve the problem of non-guided drilling has become an urgent problem that needs to be solved urgently . Through several months of experimental research, we have created a simple active chuck. This kind of chuck, proven by repeated use tests, not only has the advantages of easy processing, simple operation, easy to grasp and solve the problem of upward pushing and downward pressing, but also further improves the structure of drilling rig and lightens the migration of drilling rig in the future When the heavy manual labor, and created the conditions. Now, the structure of this chuck, the use of methods and precautions in the operation are described below: First, the structure and the role of various ministries This chuck (see photo) is connected to the vertical axis of the toothpick tube. The built-in two teeth on each tile, and the external pot-shaped jacket and other major components. In the middle of the pot-shaped coat by a tray, and on both sides of the tray,
