Abstract

The invention discloses a folded type long-stroke drilling machine. A driving mechanism is loaded on a base, output ends of the driving mechanism are connected with a lifting mechanism and a rotary mechanism respectively, a vertical column is connected with the lifting mechanism and the rotary mechanism respectively, the vertical column comprises an upper support and a lower support, the upper support is arranged at the upper end of the lower support, and the lower portion of the lower support is rotatably connected with the driving mechanism or the base through a first rotary piece; the upper portion of the lower support is movably connected with the base through a flexible inclined strut, and the lower support is supported by expanding the flexible inclined strut or the lower support is laid down by shortening the flexible inclined strut; by means of the first rotary piece and the flexible inclined strut, a movable double-support structure of the lower support is formed; the lower end of the upper support is rotatably connected with the upper end of the lower support through a second rotary piece, and a rotating track of the upper support rotating around the second rotary piece and a rotating track of the lower support rotating around the first rotary piece are located in different planes; a fixing piece is arranged between the lower end of the upper support and the upper end of the lower support.

Description

technical field

[0001] The invention relates to the field of drilling equipment, in particular to a folding long-stroke drilling machine. Background technique

[0002] The vertical shaft drilling rig is a rotary drilling rig commonly used in geological drilling. The rotary mechanism of the drilling rig has a vertical shaft, and the vertical shaft drives the drilling tool to rotate to realize feeding and guiding the drilling tool. In the vertical shaft drilling rigs widely used now, since the feeding or lifting distance of the drill pipe is completely determined by the stroke of the stroke cylinder, the stroke of the vertical shaft is limited and the stroke is relatively short. Each stroke oil cylinder completes the vertical shaft feeding and lifting actions respectively, which takes up a lot of space, is inconvenient to operate, requires many people to operate, and has high labor costs.

[0003] In order to solve the problem of short stroke, a kind of full hydraulic drillin...
