Problems solved by technology
The existing verticality detection method is to use measuring instruments such as total station, theodolite, etc. to detect, or to judge by observing the plumb line of the load with human eyes. It can be seen that the existing detection method has human judgment errors, low accuracy, and reaction slow

The invention relates to a rotary drilling machine with a real-time perpendicularity detection function and an implementation method thereof. The rotary drilling machine comprises a mast, a drill rodand a rotary platform car, the mast is fixedly connected with the rotary platform car, the drill rod is movably connected with the mast, and a traction head of the drill rod and a power head of the mast are located on the same vertical line; the traction head is provided with three distance measuring sensors, two of the distance measuring sensors are located at the left side edge and the right side edge of the traction head, the other distance measuring sensor is located at the front side edge of the traction head, and the power head is provided with three reflection flat plates correspondingto the distance measuring sensors; and the distance measuring sensors are connected with a data processing system in a cockpit through a wireless signal transmitting end. According to the rotary drilling machine, displacement changes in three directions during displacement of the drill rod are rapidly and accurately obtained through the distance measuring sensors, so that the perpendicularity of the drill rod is indirectly detected, and the measurement precision is high; and the machine is simple in structure, convenient to modify on the basis of original equipment and suitable for popularization and application.
Description
technical field [0001] The invention relates to the field of building construction, in particular to a rotary excavator with real-time verticality detection and an implementation method thereof. Background technique [0002] Rotary excavator, also known as pile driver, is suitable for various highway bridges, railways, water conservancy, urban construction and other projects. It is a fully hydraulic comprehensive drilling rig with an integrated design. The mast-type drill pipe can be rotary-dug into the ground, and its main function is to drill holes on the ground for subsequent pouring into piles as the foundation of high-rise buildings. [0003] During the downward drilling process of the rotary excavator, there is one of the most important parameters, that is, verticality. Good verticality can ensure the quality of the hole and reduce unnecessary troubles in the construction process. Therefore, real-time detection of the rotary drilling machine Verticality is extremely i...
