Abstract

The invention belongs to the technical field of drill hole drilling construction equipment and particularly relates to a drill hole horizontal angle and vertical angle synchronous measuring device andmethod. The drill hole horizontal angle and vertical angle synchronous measuring device comprises a vertical measuring rod, a first horizontal measuring rod and a second horizontal measuring rod which are hinged to one another and capable of rotating freely in a space. The vertical measuring rod and the first horizontal measuring rod in a horizontal state act jointly to measure the drill hole vertical angle, and the first horizontal measuring rod and the second horizontal measuring rod in the horizontal state act jointly to measure the drill hole horizontal angle. According to the drill holehorizontal angle and vertical angle synchronous measuring device and method, the problem that the technical requirement for the drill hole construction precision of an existing drill hole drilling construction device is hard to meet is solved, the horizontal angle and the vertical angle of a drill hole can be synchronously measured in real time to guarantee that a drilling machine keeps a predetermined angle all the time in the drilling process, thus the drilling process is accurate and controllable, and the drill hole horizontal angle and vertical angle synchronous measuring device and methodare particularly suitable for drilling construction of quasi-brittle media such as rock and concrete wall bodies.

Description

technical field [0001] The invention belongs to the technical field of drilling construction equipment, and in particular relates to a device and method for synchronously measuring the horizontal angle and the vertical angle of a drilling hole. Background technique [0002] In the process of engineering construction, it is often necessary to use various types of drilling rigs for drilling construction, and the drilling efficiency of the drilling rig is an important indicator that affects the progress of the project and the quality of the construction, especially whether the drilling accuracy of the drilling rig can meet the construction expectations. as important. It must be ensured that the drill bit can smoothly drill into the rock mass (body of wall) during the drilling process of the drilling rig, so that the depth, aperture, straightness, and inclination of the drilling hole can meet the technical requirements. [0003] Existing devices used for drilling construction, ...
