Referring to fig. 6 and 7, the second clamping unit 52 includes a clamping block 521, an anti-slip block 522, and a pressure sensor 523. A third sliding groove is vertically formed in the inner wall of the clamping space formed by the clamping block 521; the anti-skid block 522 is arranged on the third sliding groove in a vertically sliding fit mode, and part of the anti-skid block 522 extends out of the opening side of the third sliding groove; the pressure sensor 523 is disposed above the anti-skid block 522, and the sensing end faces the anti-skid block 522.
The detection unit is pressure sensor 523 in this embodiment, and the part that non-skid block 522 stretches out the third spout is used for the fixed measuring stick 10 of centre gripping or dipperstick, and when second clamping unit 52 drove measuring stick 10 or dipperstick downstream, acts on the power of pressure sensor 523 and then judges the size of resistance through detecting non-skid block 522. When the pressure measured by the pressure sensor 523 reaches a set value, it represents that the insertion of the measuring rod 10 is completed or the measuring scale is bottomed. The specific resistance setting value may be set according to actual conditions, which is not limited in this embodiment.
As shown in fig. 7, in some possible embodiments, there are two pressure sensors 523, two pressure sensors 523 are respectively disposed on two opposite sides of the anti-skid block 522, and the sensing end faces the anti-skid block 522. This embodiment is through additionally increasing a pressure sensor 523 in the below of non slipping spur 522, and measuring the completion, can detect the size of pull out power when upwards extracting measuring stick 10, be convenient for understand the equipment state better.
Referring to fig. 10, in some possible embodiments, the first pair of joints of the measuring rod 10 is provided with a slot 11, and the second pair of joints is provided with an insertion block 12; the side wall of the slot 11 is radially provided with a limit groove, and the measuring rod 10 further comprises a limit mechanism, wherein the limit mechanism comprises a limit ball 13 and a second elastic part 14. The limiting ball 13 is arranged in the limiting groove in a sliding manner; the second elastic piece 14 is arranged in the limiting groove, and two ends of the second elastic piece 14 are respectively abutted against the limiting ball 13 and the inner wall of the limiting groove; the insert block 12 is provided with a limit concave hole 15 matched with the limit ball 13 in a clamping manner.
In this embodiment, the adjacent measuring rods 10 are inserted and matched with the insertion block 12 and the insertion slot 11, and the magnetic members 18 may be respectively disposed in the insertion block 12 and the insertion slot 11, so that the adjacent measuring rods 10 are detachably connected by using magnetic force. The spacing ball 13 of stop gear and the combined action of second elastic component 14 all need certain power when pegging graft or extracting measuring stick 10, can prevent that measuring stick 10 from breaking away from the dipperstick in the use.
The second elastic member 14 may be a spring, a rubber block, or other elastically deformable component.
Due to the fact that a muddy water mixture (usually, mud generated by underground water or a mud retaining wall) exists in the rotary drilling hole after construction, muddy water is not prone to flowing out after entering the limiting groove, and the limiting mechanism is prone to being blocked. To solve the above problem, referring to fig. 10, in some possible embodiments, the first pair of joint ends of the measuring rod 10 is provided with a sealing groove around the slot 11, and a sealing ring 17 is arranged in the sealing groove. The joint surface between the measuring rods 10 is sealed by the seal ring 17, and muddy water can be prevented from entering the seal groove.
Because muddy water mixture (usually because the mud that underground water body or mud dado produced) exists in the downthehole soon after the construction, hectometre rope is the nylon braided rope, can the adhesion mud between rope surface and the fibrous gap of nylon, need wash after the measurement is accomplished, and the washing degree of difficulty is big.
In order to solve the above problem, referring to fig. 1 and 4, in some possible embodiments, the rotary drilling depth measuring device 1 further includes a cleaning assembly 60, and the cleaning assembly 60 includes a plurality of flushing nozzles arranged along the circumferential direction of the measuring scale.
It is to be understood that, the parts in the foregoing embodiments may be freely combined or deleted to form different combination embodiments, and specific contents of each combination embodiment are not described herein again, and after this description, it may be considered that the present disclosure has described each combination embodiment, and can support different combination embodiments.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
