Title:
DRILLING DEVICE FOR GEOLOGICAL EXPLORATION
Document Type and Number:
WIPO Patent Application WO/2021/237452
Kind Code:
A1
Abstract:
Disclosed is a drilling device for geological exploration, the device comprising: a sliding table (3), hydraulic telescopic rods (5) and a base (6), wherein four groups of the hydraulic telescopic rods (5) are fixedly mounted on the top of the base (6), and two groups of slide sleeves (10) are fixedly mounted on the top of the hydraulic telescopic rods (5) by means of springs (11); the sliding table (3) is slidably mounted between the slide sleeves (10) by means of slide wheels (1002); an electric motor (2) is fixedly mounted on the top of the sliding table (3) by means of a protective frame (1); a drill rod (4) penetrating the sliding table (3) and the base (6) is mounted at an output end of the electric motor (2); a movable protective frame (401) is slidably mounted on the top of the base (6) by means of a slide rail assembly on a slide slot (601); the drill rod (4) penetrates the base (6) and the movable protective frame (401), with a drill bit (9) fixedly mounted thereon. According to the drilling device for geological exploration, the movable protective frame is slidably mounted between the slide slot (601) and the drill rod (4), such that the drill rod (4) can be better protected when the drill rod (4) moves by using the slide slot (601); and the springs (11) are mounted between the hydraulic telescopic rods (5) and the sliding table (3), such that the vibration of the entire device when the drill rod (4) is working can be effectively reduced.
