Abstract

Provided is a movable type hole drilling device. The movable type hole drilling device comprises a shell (2). The lower portion of the shell (2) is fixedly connected with an idler wheel installation part (14). The lower portion of the idler wheel installation part (14) is provided with idler wheels (20) used for moving the hole drilling device. The upper portion of the idler wheel installation part (14) is capable of removably placing weight blocks (140) used for providing downward pressure during the hole drilling process. The upper portion of the shell (120) is provided with a hole drilling driving motor (2). The hole drilling driving motor (2) is in power connection with spline housing pipe fittings (5). The spline housing pipe fittings (5) are matched with spline shafts arranged on the upper portions of spline shaft connecting pieces (4). The lower portions of the spline shaft connecting pieces (4) are provided with a coupling sleeve. A concave portion of the coupling sleeve is used for containing a minor diameter part (42) on the upper portion of a drill driving shaft (40), and the coupling sleeve is fixedly connected with the drill driving shaft (40) through longitudinal extending fastening bolts (52).

Description

technical field [0001] The invention relates to the field of drilling, in particular to a movable drilling device. Background technique [0002] It is often necessary to carry out drilling operations on large areas, such as large deck surfaces, drilled surfaces of large steel plates, etc. [0003] Existing mobile drilling devices are often small in size and low in automation. The ingredients that require manual manipulation are high. [0004] 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 [0005] The purpose of the present invention is to provide a movable drilling device, which can flexibly drill various parts of the drilling surface. [0006] According to one aspect of the present invention, a movable drilling device includes a housing, the lower part of the housing is fixedly connected with a roller mounting part, and the lower part of the roller mounti...
