Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail:
With reference to shown in Fig. 1 and Fig. 3, the coal mine down-hole drilling degree of depth real-time detection apparatus of the present embodiment includes laser displacement sensor C, it is fixed on the sidewall of rig bracket 1 of underground coal mine rig, the laser-bounce plate C1 being positioned at its front is fixed on the bottom of gyroscope 2 of underground coal mine rig, the displacement that laser displacement sensor C is current for detecting the unit head 3 of underground coal mine rig；The transmission oil pressure that clamper pressure transducer D is current for detecting the clamper 6 of underground coal mine rig；The transmission oil pressure that chuck pressure sensor F is current for detecting the chuck 4 of underground coal mine rig, clamper pressure transducer D and chuck pressure sensor F is corresponding respectively to be installed on the hydraulic circuit of clamper 6 and chuck 4 (such as near a fast joint place of the clamper oil circuit of the operation you of underground coal mine rig and chuck oil circuit)；Master controller G is for the duty current according to the transmission oil pressure that the transmission oil pressure that clamper 6 is current is current with chuck 4 corresponding acquisition clamper 6 and chuck 4, the duty current according to clamper 6 and chuck 4 and the current displacement meter of unit head 3 calculate the drilling depth of drill bit 7, and by its real-time output display；Whether drilling rod detection sensor is currently in the cavity of unit head 3 for the drilling rod 5 detecting underground coal mine rig, if being not in the cavity of unit head 3, producing alarm signal and sending to master controller G.This drilling rod detection sensor includes the clamper Hall element A being fixed on clamper 6 front end face, and is fixed on the chuck Hall element B on chuck 4 front end face；When clamper Hall element A and/or chuck Hall element B detects that institute's drilling rod 5 is not presently within the cavity of unit head 3, corresponding output alarm signal, thus may determine that whether band bar runs unit head 3, namely judges whether unit head 3 produces effective displacement accordingly.
Wherein, master controller G is arranged on the operating board of underground coal mine rig, and it includes CPUG1(such as single-chip microcomputer etc.) and the laser displacement sensor interface G2, chuck pressure sensor interface G3, clamper pressure sensor interface G4, chuck Hall element interface G5, clamper Hall element interface G6, communication interface with pc G7, the external memory storage G8 that are connected with CPUG1 respectively and arrange for parameter, inquiry, show in real time the display G9 of drilling depth.
The detection process of above-mentioned coal mine down-hole drilling degree of depth real-time detection apparatus approximately as:
First, clamper pressure transducer D detects the transmission oil pressure that clamper 6 is current in real time, and chuck pressure sensor F detects the transmission oil pressure that chuck 4 is current in real time.
Secondly, before certain boring procedure, clamper 6 is caused to unclamp the drilling rod 5 of underground coal mine rig gradually when the clamper pressure transducer D transmission oil pressure recorded is increased to default first threshold D0 by zero, and when the chuck pressure sensor F transmission oil pressure recorded by zero increase to default Second Threshold F0 cause chuck 4 clamping drilling rod 5 gradually time, master controller G record unit head 3 the first displacement initial value C0；
Then, starting this boring procedure, displacement detecting sensor C detects the displacement that unit head 3 is current in real time, and unit head 3 starts into brill or moves back brill.
nullAgain，In this boring procedure，After certain time，Clamper 6 is caused to clamp drilling rod 5 gradually when the clamper pressure transducer D transmission oil pressure recorded is reduced to the 3rd default threshold value D1 by the first rated pressure value，And when transmission oil pressure the second rated pressure value that chuck pressure sensor F records be reduced to the 4th default threshold value F1 cause chuck 4 to unclamp drilling rod 5 gradually time，If now clamper Hall element A and chuck Hall element B all detects when drilling rod 5 is currently in the cavity of unit head 3，Then master controller G reads the displacement of the displacement detecting sensor C unit head 3 currently recorded，And record the first shift value C1 of the unit head 3 that now displacement detecting sensor C records，First shift value C1 is deducted the first displacement initial value C0 and obtains the drilling depth of this boring procedure，If C1-C0 > 0，Then illustrate that current drill bit 7 is advancing，If C1-C0 < 0，Then illustrate that current drill bit 7 is retreating；And if a drilling target has repeatedly boring procedure, then the drilling depth of each boring procedure gained is added up by master controller G in real time, currently total drilling depth can be obtained, and by currently total real-time output display of drilling depth, owing to master controller G has communication interface with pc G7, drilling depth can also be uploaded to host computer as required, thus realizing remote online monitoring and monitoring.
Above embodiments is only that the preferred embodiment of the present invention is described; not the scope of the present invention is defined; under the premise designing spirit without departing from the present invention; various deformation that technical scheme is made by this area ordinary skill technical staff and improvement, all should fall in the protection domain that claims of the present invention are determined.
