Embodiment
Be described in detail below in conjunction with the accompanying drawing specific embodiments of the invention:
With reference to shown in Figure 1; The sounding gear of the piling machinery of present embodiment comprises acceleration transducer 1, PLC 2 and display screen 3; Wherein, Acceleration transducer 1 is installed on the working end of piling machinery (for example any on the bucket end of the drilling bucket of rotary drilling rig, continuous wall grab etc. do not influence on the position of its working end operate as normal), and it is used for the descending and up process in the working end, and the current acceleration of collecting work end also exports PLC 2 in real time; Owing to adopt wired connection between acceleration transducer 1 and the PLC 2, to improve the antijamming capability of transmission signals; 2 of PLC are used for the acceleration of the current output of acceleration transducer is carried out the speed that integration obtains correspondence; And this speed is carried out integration obtain the current range ability in working end; Calculate the degree of depth and the working end depth in current perforate of current perforate according to the current range ability in working end, and the degree of depth and the working end depth in current perforate of current perforate is presented on the display screen of piling machinery in real time.Certainly; Acceleration transducer 1 in the sounding gear of the piling machinery of present embodiment also can replace to speed pickup; Its difference is; PLC directly just can obtain the current range ability in working end to this rate integrating when receiving the current speed in working end that speed pickup collects.
Below in conjunction with shown in Figure 2, the depth measurement process of the sounding gear of the piling machinery of present embodiment is described:
Step S101, before the working end was descending, the clear command that PLC reception display screen sends carried out zero clearing to the degree of depth of current perforate.Because piling machinery is when work, a period of time is tunneled in its working end in perforate after, the native stone storage silo in it can be saved bit by bit full native stone; At this moment the working end will stop to tunnel and be lifted out perforate and the native stone in its native stone storage silo is thrown drawn off perforate, and then gets in the perforate and tunnel next time, so back and forth; Until accomplishing the driving requirement, therefore, before the working end is descending; PLC can receive the clear command that display screen sends the degree of depth of current perforate is carried out zero clearing; So that next depth measurement, usually, the zero clearing step can be thrown to unload in the process and accomplished at native stone.
Step S102, in the descending process in working end, the descending acceleration that the real-time collecting work end of acceleration transducer is current also exports PLC to.Certainly, the startup of acceleration transducer, duty such as stop and also controlling by PLC.
Step S103, PLC carry out integration according to formula V=at to current descending acceleration and obtain corresponding downstream rate.Wherein, a is an acceleration, and t is a downgoing time, and V is a downstream rate.
Step S104, PLC carry out integration according to formula S=Vt to downstream rate and obtain the current Bottom Runby in working end.Wherein, S is a Bottom Runby, and t is a downgoing time, and V is a downstream rate.
Step S105; Bottom Runby when the PLC Bottom Runby that the working end is current deducts the working end and arrives the perforate upper end from the lower end of descending beginning to working end obtains the degree of depth of current perforate, and the depth of working end in the current perforate then degree of depth with current perforate is identical.
Step S106, PLC is presented at the degree of depth and the working end depth in current perforate of current perforate on the display screen of piling machinery in real time.Usually be shown as the real-time histogram that has depth value.
Step S107, in the up process in working end, the up acceleration that the real-time collecting work end of acceleration transducer is current also exports PLC to.
Step S108, PLC carry out integration to current up acceleration and obtain corresponding speed uplink.
Step S109, PLC carry out integration to speed uplink and obtain the current Top Runby in working end.
Step S110, PLC deducts the current Top Runby in current perforate in working end with the degree of depth of current perforate and obtains the depth of working end in current perforate.
Step S111, PLC is presented at the degree of depth and the working end depth in current perforate of current perforate on the display screen of piling machinery in real time.
Step S112 repeats above-mentioned steps, until accomplishing the driving requirement.
Above embodiment describes preferred implementation of the present invention; Be not that scope of the present invention is limited; Design under the prerequisite of spirit not breaking away from the present invention; Various distortion and improvement that the common engineering technical personnel in this area make technical scheme of the present invention all should fall in the definite protection domain of claims of the present invention.
