Drill rod fixing device for geotechnical engineering investigation

Abstract

The invention discloses a drill rod fixing device for geotechnical engineering investigation. Lifting screws are arranged on a base, a lifting plate is arranged on the lifting screws, a supporting plate is arranged on the lifting plate through guide cylinders, first springs, guide rods, first electromagnets and hinged seats, a sliding base is arranged on the supporting plate, a driving motor is arranged on the sliding base, and the driving motor is connected with a drill rod. A driven gear is arranged on the outer side of the sliding base, a driving gear is connected to the driven gear, a rotating shaft is arranged on the driving gear, a cavity with an opening formed in the bottom face is formed in the rotating shaft, a second spring is arranged in the cavity, the bottom end of the secondspring is connected with a movable rod, and second electromagnets are arranged at the top end of the movable rod and on the top face of the cavity. The lifting plate is provided with a rotating base,a rotating cylinder is arranged on the rotating base, and the rotating cylinder is in transmission connection with the lifting screws. According to the drill rod fixing device, the height and angle ofthe drill rod can be adjusted, meanwhile, wiring is facilitated, and the drill rod fixing device is flexible and convenient to use.

Description

technical field [0001] The invention belongs to the field of geotechnical engineering, and in particular relates to a drilling pipe fixing device for geotechnical engineering investigation. Background technique [0002] Geotechnical engineering is to solve rock mass and soil engineering problems, including foundation and foundation, slope and underground engineering, etc. A steel pipe with threads at the end is used to connect the surface equipment of the drilling rig and the drilling and grinding equipment or the bottom hole device at the bottom of the drilling well. The purpose of the drill pipe is to transport the drilling mud to the drill bit and raise, lower or rotate the bottom hole device together with the drill bit , The drill pipe needs a fixed frame to fix it during use to prevent deviation. [0003] Among them, the height and angle of the drill pipe cannot be adjusted when the existing drill pipe holder for geotechnical engineering investigation is in use. For so...

Problems solved by technology

[0003] Among them, the height and angle of the drill pipe cannot be adjusted when the existing drill pipe holder for geotechnical engineering investigation is in use. For some construction sites with uneven ground, it is difficult to ensure that the drill pipe holder is in a flat position when it is fixed. state, so it is difficult to adjust the drill pipe to the vertical downward state in the vertical plane when fixing the drill pipe, resulting in inconvenient construction, and at the same time, it is inconvenient to route, the flexibility is not strong, and the limitations are relatively large
