Angle-adjustable engineering geological drilling machine

Abstract

The invention provides an angle-adjustable engineering geological drilling machine, and relates to the technical field of geological exploration. The angle-adjustable engineering geological drilling machine comprises a supporting mechanism, wherein a connecting seat for supporting a rotating mechanism is mounted on the supporting mechanism; a shell for protecting the rotating mechanism is mountedat the bottom of the supporting mechanism; four universal wheels convenient to move are mounted at the bottom of the supporting mechanism; a connecting mechanism which is rotatably connected is mounted on the supporting mechanism; and a rectangular limiting groove is formed in the middle of the connecting mechanism. A worm gear A is arranged at the bottom of a base, a rotating shaft B of a worm gear is fixedly connected with a connecting plate, when the worm gear rotates, the connecting plate can be driven to rotate, thus, the rotating shaft B drives the connecting plate to rotate to adjust the circumferential rotating angle of a drilling mechanism, and the drilling mechanism can conveniently sample different positions; and a worm gear B is arranged on one side of a connecting rod of a polished rod, thus, the connecting rod rotates to drive the polished rod to swing, and the swinging angle of the drilling mechanism is adjusted.

Description

technical field [0001] The invention belongs to the technical field of geological survey, and more specifically relates to an angle-adjustable engineering geological drilling rig. Background technique [0002] The purpose of geotechnical investigation is to provide engineering geological basis for the foundation design and construction of the construction drawing stage of the proposed building, and to propose plans for the utilization, remediation and transformation of the foundation soil of the site according to the engineering characteristics of the proposed building and the engineering geological conditions of the foundation soil. And analyze and demonstrate it in terms of technology and economy. During geotechnical survey and sampling, geological drilling rigs will be used to drill. The existing ordinary engineering geological drilling rigs supplied in the domestic and foreign markets can only drill straight holes in the vertical plane. hole, in the field of geological d...

Problems solved by technology

[0007] In order to solve the above-mentioned technical problems, the present invention provides an angle-adjustable engineering geological drilling rig to solve the problem of adjusting the swing angle of the geological drilling rig to drill inclined holes. Tightening the screws is not only troublesome, but also the gravity of the rotating tower will be concentrated on the screws, and the screws may bend and break, making the rotating tower unusable. The base lacks a circumferential rotation structure. When changing the direction of the geological drilling rig, it is necessary to manually rotate the whole body to a certain angle. It will be laborious to adjust the rotation angle. Heat will be generated during the drilling process of the drilling rig, and it is necessary to dissipate the heat of the drilling rig in time.
