Description
Technical field
The utility model relates to rock mass rangefinder fields, and in particular to a kind of rock displacement measurement dress based on sound ranging
It sets.
Background technique
Existing surrounding rock separation layer monitor is usually that anchor fluke is sent into drilling, and anchor fluke connects the drawing of tail end by wirerope
Line rheostat.The absciss layer variation of country rock is converted rheostatic change in resistance by bracing wire rheostat, and monitor is to bracing wire rheostat
Measurement result and installation initial value are compared, and its difference, that is, current roof rock absciss layer value are shown by sampling, measurement
On charactron, but anchor fluke wirerope is connect with sensor, poor sealing.Secondly, rock stratum is unstable, wirerope may cause
Extruding, which is examined, to fracture.
Summary of the invention
To overcome the shortcomings of existing technologies, the utility model provides a kind of rock displacement measurement dress based on sound ranging
It sets, the technical solution of the utility model is:
A kind of rock displacement measuring device based on sound ranging, including upper sleeve (1), ultrasonic displacement sensor
(2), lower sleeve portion (3) and measurement display instrument (4), the periphery at the top of the upper sleeve (1) are equipped with upper hangnail；The lower part set
The top of cylinder (3) is protruded into from the bottom of upper sleeve, and that slides is sleeved in upper sleeve (1), under the lower sleeve portion (3)
The periphery in portion is equipped with lower hangnail；A ultrasonic displacement is fixedly installed at the top of the lower sleeve portion (3) in the upper sleeve
Sensor (2)；The ultrasonic displacement sensor (2) connect with the measurement display instrument (4).
The measurement display instrument (4) is fixedly mounted on lower sleeve portion (3), and the circuit part of the measurement display instrument includes
CPU control unit and the detection part being connect with CPU control unit, power management section and display portion；The CPU control
Unit processed uses MSP430 series monolithic；The display portion uses three high brightness numeral method data.
The utility model has the advantages that:
1, using casing protection, increase instrument leakproofness；
2, phenomena such as preventing sensor from being broken by palisades abrasion using casing protection；
3, measurement accuracy is improved using sound ranging.
4, the workload for reducing coal miner also avoids the case where human error occur, improves monitoring precision
And monitoring efficiency.
5, be not in because coal dust covering or measuring scale get rusty caused by can not observing monitor fail the case where sight
Survey is also more intuitive, does not need to calculate again, anyone irradiates monitor using mine lamp, can show current absciss layer immediately
Value.
Detailed description of the invention
Fig. 1 is the agent structure schematic diagram of the utility model.
Fig. 2 is the circuit part schematic diagram that display instrument is measured in Fig. 1.
Specific embodiment
Further describe the utility model combined with specific embodiments below, the advantages of the utility model and feature will be with
Description and it is apparent.But examples are merely exemplary for these, does not constitute any restrictions to the scope of the utility model.
It will be understood by those skilled in the art that can be to the utility model skill under the spirit and scope without departing from the utility model
The details and form of art scheme are modified or are replaced, but these modifications and replacement each fall within the protection scope of the utility model
It is interior.
Referring to Fig. 1 and Fig. 2, the rock displacement measuring device based on sound ranging that the utility model relates to a kind of, including it is upper
The periphery of portion's sleeve 1, ultrasonic displacement sensor 2, lower sleeve portion 3 and measurement display instrument 4,1 top of upper sleeve is equipped with
Upper hangnail is fixed to detected rock mass depth base position by upper hangnail；The top of the lower sleeve portion 3 is from upper sleeve
Bottom is protruded into, and that slides is sleeved in upper sleeve 1, and the periphery of 3 lower part of lower sleeve portion is equipped with lower hangnail, passes through lower hangnail
Lower sleeve portion and measurement display instrument 4 are fixed in detected rock mass；The top of lower sleeve portion 3 in the upper sleeve
It is fixedly installed with a ultrasonic displacement sensor 2；The ultrasonic displacement sensor 2 is connect with the measurement display instrument 4.
The measurement display instrument 4 is fixedly mounted in lower sleeve portion 3, and the circuit part of the measurement display instrument includes CPU control
Unit processed and the detection part being connect with CPU control unit, power management section and display portion；The CPU controls single
Member uses MSP430 series monolithic；The display portion uses three high brightness numeral method data.
The ultrasonic wave of ultrasonic displacement sensor transmitting touches 1 top back reflection of upper sleeve back by ultrasonic displacement
Sensor is received and is transferred in measurement display instrument 4, and the parameter of measurement 4 basis of display instrument calculates relative distance value；Top set
Relative position between cylinder and lower sleeve portion is relatively moved with formation variations, while the detection of ultrasonic displacement sensor 2 is in place
Move variation.The measurement display instrument 4 is exposed at outside rock mass, and monitor is usually in standby, and is entered when being irradiated by mine lamp aobvious
Show state, monitor samples ultrasonic displacement sensor, measures, and measurement result and installation initial value is compared, and will
Its difference, that is, current roof rock absciss layer value is shown on three high brightness charactrons.
