Optar and blasthole coaxial line, and then guarantee the axial line of laser range finder and the axis parallel of blasthole；Again by Laser Measuring
Distance meter slide downward is adjusted until gag lever post and blasthole EDGE CONTACT, keeps the test side of laser range finder concordant with blasthole aperture,
Convenient for the measurement to blast hole depth；It thereby ensures that the accuracy of measurement result, and improves work efficiency.
Detailed description of the invention:
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the A direction view of Fig. 1.
The components in the drawings are labeled as follows: mobile base 1, through slot 2, scroll chuck 3, laser range finder 4, gag lever post 5,
Driving motor 6, output shaft 7, torque sensor 8, controller 9, stud 10, through-hole 11, locking nut 12, bottom plate 13, multi-directional ball
14, claw 15, elevating mechanism 16.
Specific embodiment:
As depicted in figs. 1 and 2, blast hole depth measuring device comprising scroll chuck 3, mobile base 1, laser range finder
4；Mobile base 1 includes bottom plate 13 and at least three multi-directional balls 14 for being fixed on 13 bottom of bottom plate；The top horizontal of mobile base 1
It is fixed with scroll chuck 3, offers the one-to-one through slot 2 of claw 15 with scroll chuck 3 at the top of mobile base 1, often
The end of a claw 15 passes through the lower section that corresponding through slot 2 is placed in mobile base 1, and slides and be arranged along through slot 2；In mobile base 1
Bottom end the laser range finder 4 of vertical sliding setting is connected with by elevating mechanism 16, laser range finder 4 and scroll chuck 3 are same
Axis setting；Gag lever post 5, gag lever post 5 and the staggered setting of claw 15 are fixed in the lower horizontal of laser range finder 4；Driving
Three claws 15 of scroll chuck 3 open and are connected to the inward flange of blasthole, while mobile base 1 being driven to be moved, and make three
Dog chuck 3 and blasthole coaxial line, and then make the laser range finder 4 for being fixed on 1 bottom of mobile base and blasthole coaxial line, Jin Erbao
The axial line of laser range finder 4 and the axis parallel of blasthole are demonstrate,proved, thereby ensures that the accuracy of measurement result；Again by Laser Measuring
It is flat that 4 slide downward of distance meter adjusts the test side for making laser range finder 4 until gag lever post 5 and blasthole EDGE CONTACT and blasthole aperture
Together, convenient for the measurement to blast hole depth.
It further includes driving motor 6, is fixed with driving motor 6 in the top horizontal of mobile base 1, driving motor 6 it is defeated
7 activity of shaft is plugged in the power input hole of scroll chuck 3；Three claws 15 of scroll chuck 3 are driven by driving motor 6
Opening and close up, be conducive to improve blast hole depth measurement efficiency.
Torque sensor 8 is fixed on output shaft 7, torque sensor 8 is electrically connected with 9 input terminal of controller, controller 9
Output end is electrically connected with driving motor 6；When driving motor 6 drives three claws 15 to be connected to the inward flange in blasthole aperture, and it is defeated
When the torque of shaft 7 reaches setting value, by signal Real-time Feedback to controller 9, driving motor 6 is controlled by controller 9 and is stopped
Operation, and then it is more advantageous to protection driving motor 6, it avoids overlond running and damages.
Elevating mechanism 16 includes stud 10 and locking nut 12；The middle part of mobile base 1 offers coaxial with scroll chuck 3
Through-hole 11, laser range finder 4 is slidably arranged in through-hole 11；The top vertical of laser range finder 4 is fixed with stud 10, stud
