Problems solved by technology

Because the mass of the rotary drilling rig itself is larger, the inertia is also greater. Therefore, in the process of automatic rotation when the rotation speed is large, it is difficult to stop smoothly when the rotation speed is high. When it is small, it is time-consuming, that is to say, the current automatic rotation control method has the problem of low control accuracy, so it is difficult to stop if it appears at the zero position, or it is time-consuming and the ideal efficiency of automatic control cannot be achieved.
[0004] Similarly, there is also the problem of low control accuracy in other control systems (such as depth control and inclination control) of rotary drilling rigs.

Abstract

The invention provides a rotary drilling rig automatic control method and system and rotary drilling rig equipment. The rotary drilling rig automatic control method comprises the following steps thatthe actual parameter change value during the movement in preset time from a first preset position to a second position is calculated; and the actual movement parameter change value is compared with astandard movement parameter change value, if not equal, the magnitude values of a control current is increased or decreased according to the adjusting relation of the movement parameter speed and theoutput control current. The rotary drilling rig automatic control method and system and the rotary drilling rig equipment are provided, and automatic control precision can be provided.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to an automatic control method and system for a rotary drilling rig, and rotary drilling rig equipment. Background technique [0002] Rotary drilling rig is a construction machine suitable for hole-forming operations in building foundation engineering. The rotary drilling rig mainly includes a crawler chassis and a rotatable boarding platform arranged on the chassis, and a drill pipe is installed on the boarding platform. When the rotary drilling rig uses the drill pipe to drill holes on the ground, it is necessary to remove the drill pipe from the drill hole every once in a while, and drive the drill pipe to leave the drilling position through the rotation of the boarding platform on the chassis. After rotating to the unloading position, stop the rotation, then make the excavated materials fall off, and then control the loading platform to drive the drill pipe to rot...
