A kind of brill core degree of depth measuring apparatus
Technical field
The invention belongs to drilling core examination technical field, particularly one bores core depth mechanism.
Background technology
Core boring sampling is a kind of conventional method detecting concrete quality, refer to and adopt brill core machine to drill through concrete sample as requested on shaping concrete, then by detecting the various performance parameters of the concrete sample got thus reaching the object detecting concrete quality.
Core boring sampling generally realizes by boring core machine, and bore core machine and generally comprise handwheel, turning axle and drilling pipe, wherein, turning axle is connected with the center of handwheel, and drilling pipe is connected with turning axle and drilling pipe overlaps with rotating shaft axis.In time boring core, fixed cross beam is first adopted to be fixed by brill core machine, then open and bore core machine, drilling pipe is rotated relative to turning axle, and then staff rotates handwheel, and turning axle rotates, under the effect of boring core machine leading screw, drilling pipe can be slowly close to concrete, rotates the input that handwheel realizes the drilling pipe degree of depth, thus complete core boring sampling by staff.
But, in existing core boring sampling process, for constant depth core boring sampling, i.e. quantitative core boring sampling, often occurring destroying concrete inner structure because sampling dark, causing in type building interior to destroy, thus make it there is potential safety hazard, or because the degree of depth of sampling does not reach requirement, and need sub-sampling again, it is greatly not inconvenient to bring to Practical Project detection; For on-fixed degree of depth core boring sampling, i.e. non-quantitation core boring sampling, after core boring sampling, need the thickness of special messenger to got sample to test, efficiency is too low.
Therefore, a kind of brill core degree of depth measuring apparatus, this brill core degree of depth measuring apparatus can to bore in core process can Real-Time Monitoring bore core machine drill through the degree of depth, effectively can reduce and bore sample and cross dark and destroy understructure or bore sample and cross shallow and carry out secondary and bore core, also can avoid drilling through rear special messenger and carry out thickness measuring, increase work efficiency, become those skilled in the art's problem demanding prompt solution.
