Embodiment approach

[0026] As an embodiment of the present invention, the lower end of the drilling shaft 8 is tapered and provided with drilling threads. When working, the drilling shaft 8 can be more easily entered into the depth of rock and soil.

[0027] As an embodiment of the present invention, the fixed adjustment device 13 includes a first fixed plate 19, a second fixed plate 20 and a fixed bolt 21, the first fixed plate 19 is symmetrically fixedly connected to the limiting plate 22 on one side, and the limiting plate 22 is connected to the limiting plate 22. The support rods 12 are fitted together, and the fixing bolts 21 pass through the limiting plate 22 to securely connect the first fixing plate 19 and the second fixing plate 20 . During operation, the first fixing plate 19 and the second fixing plate 20 are prevented from rotating or laterally sliding.

[0028] As an embodiment of the present invention, the lower ends of the first fixed plate 19 and the second fixed plate 20 are arc...

Abstract

The invention discloses a novel drilling device for geotechnical engineering investigation, and belongs to the technical field of drilling devices for investigation. The novel drilling device comprises a drilling device body and support devices, the support devices are arranged on three sides of the drilling device body, and the drilling device body comprises a first mounting plate, a second mounting plate and a third mounting plate. A motor groove is formed in the middle of the third mounting plate, a first motor is fixedly mounted in the middle of the upper end of the second mounting plate,an output shaft of the first motor is fixedly connected with a drilling shaft, second motors are mounted on the three corners of the third mounting plate respectively, and the output shafts of the second motors are fixedly connected with lead screws of which the lower ends are rotatably connected with the first mounting plate. The lead screws are in threaded connection with the second mounting plate, ejector rods are fixedly connected to three sides of the lower end of the third mounting plate, the lower ends of the ejector rods are fixedly connected with the first mounting plate, and the ejector rods penetrate through the second mounting plate and are slidably connected with the second mounting plate. On a slope, the device can be adjusted to be horizontal, so that supporting legs are stable, deviation is prevented, and the drilling hole quality is guaranteed.

Description

technical field [0001] The invention relates to the technical field of drilling devices for surveying, in particular to a novel drilling device for geotechnical engineering surveying. Background technique [0002] Geotechnical engineering survey refers to the activities of ascertaining, analyzing and evaluating the geological, environmental characteristics and geotechnical engineering conditions of the construction site according to the requirements of the construction project, and preparing survey documents. During the survey process, drilling devices are required. [0003] However, due to the poor geological conditions in the field, the existing drilling equipment is unstable when drilling, and is prone to deviation, resulting in drilling deviation; Stablize. [0004] Based on this, the present invention designs a novel geotechnical engineering investigation drilling device to solve the above problems. Contents of the invention [0005] In order to solve the above prob...
