Abstract
The utility model is related to a kind of deep hole varying aperture measuring devices, it is characterised in that by end umbrella device, telescopic rod device, bar shaped graduated scale device composition.End umbrella device is mainly made of triangle fork, spring, and triangle fork is hingedly made of three rough draw points with small steel loop, and for spring between small steel loop and telescopic rod end, monnolithic case is in umbrella.Telescopic rod device is made of the fine steel tube of several different-diameters with steel wire rope, and the fine steel tube of different-diameter mutually covers, and steel wire rope is located at steel duct, and one end passes through spring to connect drum rim, and one end connects bar shaped graduated scale.Bar shaped graduated scale device is a graduated steel ruler of mark, and steel ruler width is less than steel pipe minimum diameter in telescopic rod, for reading data.Advantageous effect of the present utility model is：Deep hole varying aperture measuring device makes the thick steel needle opened touch deep hole hole wall by end umbrella device, learns pore size by bar shaped graduated scale reading, realizes the data monitoring in deep hole different location aperture.The utility model can be repeated several times use simultaneously, easy to operate, economical and practical.
Description
Technical field
The utility model is related to apply a kind of deep hole varying aperture measuring device under mine.
Background technology
With being continuously increased for pit mining depth, underworkings surrouding rock stress is increasing, assembles in country rock a large amount of
Deformation energy, the phenomenon that leading to surrouding rock deformation unstability, are also more and more common, and great security risk is caused to the safe working of mine.
It is to reduce bump by the unloading technology deformation controlling for rock surrounding gateways that drills, prevents the important of roadway surrounding rock unstability from arranging
It applies.Meanwhile it is the important means for studying drilling unloading technology effect to be monitored to mine deep part wall rock drill-hole varying aperture.Cause
This, which designs and develops deep hole varying aperture measuring device, can realize the dynamic monitoring deformed to deep hole different location aperture, provide deep hole
Different location pore size data provides foundation for drilling release and supporting roadway surrounding rock etc..
Utility model content
Dynamic measurement, and traditional measurement are implemented to deep hole aperture deformation different location in order to overcome the prior art can not achieve
Measurement that tool is brought is inconvenient, the drawbacks of cannot reusing, and the utility model provides a kind of novel deep hole varying aperture and surveys
Device is measured, which is made of end umbrella device, telescopic rod, bar shaped graduated scale three parts.Not only
Dynamic monitoring can be carried out to deep hole different location aperture, while can be repeated several times uses, for drill release and roadway surrounding rock
Supporting etc. provides foundation.
In order to realize that above-mentioned task, the utility model are made of three parts, first part is to be connected to telescopic rod end
End umbrella device, second part are telescopic rod, and Part III is bar shaped graduated scale, it is characterised in that：
The end umbrella device is mainly made of triangle fork, spring, and triangle fork is hinged by three rough draw points with small steel loop
It constitutes, small steel loop is connect with the steel wire rope inside telescopic rod, hinged with telescopic rod end in the middle part of thick steel needle, and spring is located at small
Between steel loop and telescopic rod end, it is in umbrella so that small steel loop is kept certain distance, monnolithic case with telescopic rod end.
The telescopic rod device is made of the fine steel tube of several different-diameters with steel wire rope, telescopic rod by it is several not
Fine steel tube with diameter mutually covers composition, and telescopic rod end and the thick steel needle in the umbrella device of end are hinged.Steel wire rope is located at steel pipe
Inside, one end pass through spring to connect drum rim, and one end connects bar shaped graduated scale.
The bar shaped graduated scale device is a graduated steel ruler of mark, and steel ruler width is less than telescopic rod fine steel tube most
Minor diameter, steel ruler one end have a circular aperture to be connect with the steel wire rope in telescopic rod, and one end is located at outside telescopic rod.
The utility model has the beneficial effects that：Deep hole varying aperture measuring device to open thick by end umbrella device
Draw point touches deep hole hole wall, hole wall diameter is transferred out by stretching the steel wire rope in telescopic rod, by pulling out bar shaped
The size in the reading variation reflection deep hole different location aperture on graduated scale.The deep hole varying aperture measuring device can realize depth
The dynamic data monitor of hole different location aperture deformation provides foundation for drilling release and the supporting of roadway surrounding rock etc., meanwhile, by
In spring is added in the umbrella of end so that end umbrella can be closed automatically so that the utility model can be repeated several times use, this practicality
New design principle is simple, easy to operate, economical and practical.
Description of the drawings
Fig. 1 is deep hole varying aperture measuring device illustraton of model.
Fig. 2 is deep hole inside diameter measurement embodiment schematic diagram.
Figure label indicates respectively：The small steel loops of 1-, 2- thick steel needles, 3- springs, 4- telescopic rods, 5- steel wire ropes, 6- bar shapeds
Graduated scale, 7- deep holes, 8- roadway surrounding rocks, 9- anchor poles.
Specific implementation mode
The utility model is specifically installed and is measured process with reference to the accompanying drawings to be described in detail.
The first step：During deep hole varying aperture measuring device is deeply drilled, telescopic rod is adjusted, end umbrella device is placed
The position in measurement aperture is needed in deep hole.
Second step：Stretch bar shaped graduated scale, at this time the small steel loop in the umbrella device of end due to steel wire rope effect and to can
Telescopic rod is close, and spring is in compressive state, when thick steel needle free end touches deep hole hole wall, drum rim stop motion, and note
The distance for recording the movement of bar shaped graduated scale obtains the pore size at the deep hole position by conversion.
Third walks：Unclamping bar shaped graduated scale makes it be attributed to original position under the action of the spring, by deep hole varying aperture measuring device
It takes out, is repeated Step 1: step 2 measures the other position pore sizes of deep hole from drilling.
