Description

Technical Field

[0001] The utility model relates to the field of mine measurement, in particular to a three-dimensional positioning slope ruler for mine drilling. Background Art

[0002] Open-pit limestone mining must strictly control the slope angle. Too large a slope angle will cause slope instability or even landslides. Too small a slope angle will prevent the lower ore from being fully mined, affecting the economic benefits of ore mining. Traditionally, the bottom slope angle (90°) and horizontal angle (90°) are measured by visual inspection, and the inclination of the drill rod is determined using a two-dimensional slope gauge to control the slope angle. This method relies too much on the operator's own work quality for the control of the bottom slope angle and horizontal angle, and there is no accurate measurement method. Therefore, it will cause errors in the actual slope angle and cannot meet the design requirements. Utility Model Content

[0018] Specifically, one end of the buckle 1 is fixedly connected to one side of the vertical base 2, a locking nut 4 for fixing the slope calibration device 3 is provided on the back of the vertical base 2, a screw is fixedly connected to the back of the vertical base 2, a circular hole is opened on the back of the slope calibration device 3, the circular hole is interlaced with the screw, and the locking nut 4 is interlaced with the screw thread.

[0019] Furthermore, two buckles 1 are provided, and the two buckles 1 are symmetrically arranged at the top and bottom ends of one side of the vertical base 2. The buckle 1 is an existing circular buckle. By mutually clamping the buckle 1 and the drill rod, the vertical base 2 and the drill rod can be fixedly installed. The direction of the vertical base 2 is perpendicular to the direction of the clamping hole of the buckle 1. The vertical base 2 consists of a circular plate and a strip plate. A pointer is drawn on the back of the strip plate, pointing to the slope calibration device 3, so that the numerical value of the rotation angle of the slope calibration device 3 can be read by the pointer. The buckle 1 and the strip plate are connected. One side of the plate is fixedly connected, the slope calibration device 3 is arranged on the back side of the circular plate, the screw is arranged at the center position of the circular plate, the circular hole has a smooth inner wall, the screw is connected through the circular hole, so as not to limit the rotation of the slope calibration device 3, the thread on the inner wall of the locking nut 4 and the thread on the outer wall of the screw are engaged with each other, and the slope angle can be locked by rotating the slope calibration device 3, and then the locking nut 4 is rotated so that the locking nut 4 and the vertical base 2 work together to clamp the slope calibration device 3, thereby fixing the rotation angle of the slope calibration device 3.
