Rotary drilling rig, and control method, control device and control system of mast thereof

Abstract

The invention provides a rotary drilling rig, and a control method, a control device and a control system of a mast thereof. The control method comprises the following steps of receiving distance between a distance detection device and a sensor, wherein the sensor is located at any side of a combination face of a middle mast and a lower mast, and the distance detection device is located at the other side, opposite to the sensor, of the combination face of the middle mast and the lower mast; outputting a corresponding control command to control a mast standing action of the middle mast according to the distance between the distance detection device and the sensor and a preset control strategy, so that the impact on the combination face of the middle mast during the mast standing operation of the rotary drilling rig is relieved, the manual operation is reduced, and accidents are reduced.

Description

technical field [0001] The invention relates to the field of pile machinery, in particular to a control method, control device and control system for a rotary drilling rig and a mast thereof. Background technique [0002] The rotary drilling rig is a pile engineering machine used for drilling piles in the field of pile foundation engineering. Due to the harsh and special working environment, once an accident occurs, it may cause incalculable losses, so the safety and stability of the product must meet higher-level requirements. In the existing mast erecting process, the operator often needs to personally check whether the planes of the lower mast and the middle mast are combined, and then install screws to fix it. When the lower mast is combined with the middle mast, the cumbersome human operation will inevitably cause mast impact, which will reduce the service life of the components, and the operator's experience is required to be high, accidents are more likely to occur, ...

AI Technical Summary

Problems solved by technology

When the lower mast is combined with the middle mast, the cumbersome manual operation will inevitably cause the impact of the mast, which will reduce the service life of the components, and the experience requirements of the operators are high, accidents are more likely to occur, and the work efficiency is affected

Sometimes because the plane of the middle mast and the lower mast has been combined, but the operator continues to erect the mast, the hinge point seat is hit and severely deformed, resulting in product failure and affecting the use
