Installation of LVG726T dynamic tilt sensor for posture control during construction of rotary drilling rig
With the continuous rise of the domestic engineering machinery industry, rotary drilling rigs can be seen everywhere at construction sites of buildings and roads, widely used in various foundation construction such as cast-in-place piles, continuous walls, and foundation reinforcement. A rotary drilling rig is a type of pile machinery used for the construction of cast-in-place pile drilling at pile foundation engineering sites. By configuring different drilling tools and adopting corresponding drilling processes, it can be suitable for hole-making operations in various complex strata.
Rotary drilling rigs generally use hydraulic crawler-type telescopic chassis, self-lifting foldable drill masts, telescopic drill rods, and are equipped with automatic verticality detection and adjustment, as well as digital display of hole depth. The overall operation is generally controlled by hydraulic pilot control and load sensing, which can work on large construction sites, improving work efficiency and project progress.
Application of tilt sensors in monitoring rotary drilling rigs
The position of the center of gravity of the rotary drilling rig is a key factor affecting its stability. Many factors influence the overall center of gravity position of the rotary drilling rig, including static factors such as the angle between the chassis and the horizontal plane, the position of the boom mechanism, the inclination of the mast, and the weight of various components of the drilling rig; dynamic factors include applied pressure, lifting force, and rotation speed. During the drilling operation of the rotary drilling rig, it is necessary to erect the drill mast and adjust the verticality, which involves first moving the rotary drilling rig to the location of the drilling operation, and the display of the rotary drilling rig shows the working screen of the mast. The deviation of the mast in the X-axis and Y-axis directions can be observed in real-time from the mast working screen. By measuring the inclination of the respective components using the tilt sensor on the mast, the center of gravity position of each component can be calculated. Combining this with the weight of each component allows for the determination of the static center of gravity coordinates of the rotary drilling rig.
Maiko sensor tilt sensor for real-time attitude angle control of rotary drilling rigs
Drill rod end installationLVG726T dynamic high-performance tilt sensor, which can achieve real-time dual-axis attitude measurement under the motion conditions of the drill rod structure, installed on the vehicle chassis.HVT826T high-precision static tilt sensor, which can accurately measure the attitude of the vehicle body relative to the horizontal plane. The measured attitude, combined with the three-dimensional mechanical model of the rotary drilling rig, can calculate the spatial coordinates of the overall center of gravity relative to the horizontal coordinate system in real-time. When the actual center of gravity exceeds the pre-calculated safe space area of the overall center of gravity, the system issues a safety alarm, pauses the execution of the moving mechanism, and automatically or manually readjusts the center of gravity to the safe area to avoid dangerous accidents.
