A kind of mast control device of small-sized rotary drilling rig
Technical field
The utility model relates to the mast control device of a kind of small-sized rotary drilling rig, particularly a kind of small-sized rotary drilling rig.
Background technology
Since China reform and opening-up, national economy obtains rapid growth, has become the main flow of the current industrial development of China with " scientific and technical innovation, autonomous innovation ", and China's industry is progressively to intensive style, energy-saving and emission-reduction, the future development of low-carbon (LC).In order to meet the needs of small-sized rotary drilling rig whole Transporting, do not adopt the tetragonal jib lubbing mechanism of flat shape, for keeping whole gravity balance, the luffing stroke is little.And rotary drilling rig mast be to realize revolving important parts that dig operating mode, small-sized rotary drilling rig mast vertical ground when operating mode, transportation or while shutting down mast become certain security standpoint placement with ground.And mast and ground is while being less than certain angle, mast can be in driver's cabin side close proximity, therefore when the handstand mast operate, careless slightly, will cause mast and driver's cabin interference.Large-scale rotary drilling rig can exceed driver's cabin by the lifting of luffing moving handle mast and avoid interfering; And small-sized rotary drilling rig is little because of the luffing stroke, can not be promoted to driver's cabin top to mast.And when mast operating mode vertical ground, the action of operation luffing, mast can be along with the motion of swing arm, and angle will change.Now needing to operate the tractor driver, constantly to adjust mast perpendicular to the ground, thereby have a strong impact on operating efficiency.In order to solve this difficult problem, R&D institution and science and technology in enterprise personnel use for reference the jib lubbing mechanism that large-scale rotary drilling rig has parallelogram, mast angle not idle rod angle changes and the feature of variation, in constantly research, exploration, utilize modern science and technology, although obtained technically some progress, still existed the technical barrier not yet overcome in practice.
Summary of the invention
The purpose of this utility model is to overcome above deficiency, a kind of mast control device of small-sized rotary drilling rig is provided, the swing arm inclinometer Real-Time Monitoring mast that the mast obliquity sensor be provided with by mast and swing arm are provided with and the angle of swing arm and level ground, through the computing of PCL director demon, avoid mast and driver's cabin to interfere.This system automation degree is high, and reaction speed is fast, and safety is good, has improved the operating efficiency of small-sized rotary drilling rig.
The utility model solves the technical scheme that its technical problem adopts: comprise mast, the mast obliquity sensor, the swing arm inclinometer, swing arm, the PLC controller, mast stops movable mast, spacing after luffing, the luffing front limit, mast plays at a slow speed mast, mast program left limit, mast plays mast fast, mast limit switch left limit, the automatic vertical adjustment state of mast, mast is provided with the mast obliquity sensor, swing arm is provided with the swing arm inclinometer, the mast obliquity sensor is connected with the input of PLC controller with the swing arm inclinometer, the output of PLC controller and mast play at a slow speed mast, mast program left limit is connected with the luffing front limit, the output of PLC controller also stops movable mast with mast and is connected with spacing after luffing, mast plays at a slow speed mast and mast plays mast fast, mast limit switch left limit is connected, mast plays mast and the automatic vertical adjustment state of mast fast, spacing being connected after luffing, the mast control device that has formed a kind of small-sized rotary drilling rig.
The know-why that the utility model adopts is: the swing arm inclinometer Real-Time Monitoring mast that the mast obliquity sensor be provided with by mast and swing arm are provided with and the angle of swing arm and level ground, through the computing of PCL director demon, avoid mast and driver's cabin to interfere.When moving at vertical operating mode operation swing arm, mast enters the automatic vertical adjustment state of mast automatically, makes the mast angle remain perpendicular to the ground.The automatic vertical adjustment state of mast refers to the mast angle-data that the PLC controller provides according to the mast obliquity sensor, and the operation mast of automatic slowly enters plumbness.Jib lubbing mechanism refers to swing arm, amplitude oil cylinder, the assembly of support bar.Can among a small circle, adjust the distance of mast front and back.The height of mast simultaneously also can promote and fall.The PLC controller is controlled mast: the control of PLC controller to hydraulic multitandem valve, banked direction control valves, to the mast oil cylinder fuel feeding, is realized the mast action.Small-sized rotary drilling rig: the unit head moment of torsion is less than the rotary drilling rig of 100KN.m.The mast angle: when the mast vertical ground, seesaw and be expressed as Y-direction, side-to-side movement is expressed as directions X, and the PLC controller is judged as the X:0 degree; The Y:0 degree.While leaning forward, Y value is for just, and during hypsokinesis, Y value is for negative; When left-leaning (driver's cabin side), the X value is for negative; During Right deviation, the X value is for just.Mast is provided with the mast obliquity sensor, and the mast obliquity sensor tilts (X angle) for detection of mast and tilts forward and back (Y angle); Swing arm is provided with the swing arm inclinometer, and the swing arm inclinometer is for detection of swing arm front and rear angles (Y angle), the angle signal of PLC controller reception & disposal mast obliquity sensor and swing arm inclinometer.When X<-0.5 °, mean that mast is to left avertence (driver's cabin rolls tiltedly), the PLC controller is controlled mast and is stopped left avertence, and proposes mast program left limit.When-90 °<Y<-65 °, mast in the driver's cabin right side (from right side very close to), now the PLC controller is controlled mast and is played at a slow speed mast, and control after luffing spacing, while preventing from rising luffing, mast<-90 ° and interfering with car body.When Y>3 °, mast is vertical and lean forward 3 °, and the PLC controller is controlled the luffing front limit, forbids that luffing falls mast is leaned forward again.When X>-2 ° and-75 °<Y<-5 °, mast is in safe space, and the PLC controller is controlled mast and played fast mast, raises the efficiency.When mast, in-2 °<Y<2 ° with-5 °<5 ° the time, mast is substantially vertical, and the PLC controller is controlled mast and entered the automatic vertical adjustment state of mast (it is slow that speed turns), prevents that mast is too fast and is difficult to vertically.When 16 °>Y of swing arm angle>8 °, mast stops movable mast, after preventing that body gravity from leaning on very much, and has potential safety hazard.
The utility model beneficial effect is: the swing arm inclinometer Real-Time Monitoring mast that the mast obliquity sensor be provided with by mast and swing arm are provided with and the angle of swing arm and level ground, and through the computing of PCL director demon, avoid mast and driver's cabin to interfere.This system automation degree is high, and reaction speed is fast, safe, can improve the operating efficiency of small-sized rotary drilling rig.
