Abstract

The invention provides an application method of a movable drilling device. The movable drilling device comprises a shell body (2). Rolling wheel installation pieces (14) are fixedly connected to the lower portion of the shell body (2). Rolling wheels (20) are installed on the lower portions of the rolling wheel installation pieces (14) to be used for moving the drilling device. Weight blocks (140) can be removably placed on the upper portions of the rolling wheel installation pieces (14) to provide the down force during drilling. A drilling driving motor (1) is installed on the upper portion of the shell body (2) and in power connection with a spline sleeve piece (5). The spline sleeve piece (5) is matched with a spline shaft on the upper portion of a spline shaft connecting piece (4). A connecting sleeve is located on the lower portion of the spline shaft connecting piece (4). A concave part of the connecting sleeve contains an upper small-diameter part (42) of a drill bit driving shaft (40), and the connecting sleeve is fixedly connected with the drill bit driving shaft (40) through a fastening bolt (52) extending longitudinally.

Description

[0001] The present invention is an application number: 2014108089511, application date: 2014-12-23, and title of the invention: a divisional application of a movable drilling device. technical field [0002] The invention relates to the field of drilling, in particular to a method for using a movable drilling device. Background technique [0003] It is often necessary to carry out drilling operations on large areas, such as large deck surfaces, drilled surfaces of large steel plates, etc. [0004] Existing mobile drilling devices are often small in size and low in automation. The ingredients that require manual manipulation are high. [0005] Moreover, these drilling devices are often used to process smaller holes, which are difficult for the drilling of large aperture holes. Contents of the invention [0006] The purpose of the present invention is to provide a movable drilling device, which can flexibly drill various parts of the drilling surface. [0007] According t...
