By means of the digital counter for displaying the depth of a current drilled hole, the drilling depth under construction can be learned at any time, and the characteristics of visual display, time saving, labor saving, convenience in use and the like are achieved.
Description
Technical field
The utility model belongs to triangular drilling rod drilling depth field of measuring technique under the coal mine.
Background technology
In all kinds of mines of pit mining; All need geotechnical boring and carry out forward probe; Prevent various geological disasters, when geology boring in a certain position abnormal conditions takes place, need azimuth, inclination angle, the drilling depth of record boring to confirm the position that this abnormal conditions take place.At high gas or coal and the outstanding mine of gas; The construction mash gas pumping drilling is the important means of carrying out gas control; When situation such as spray orifice, crown drill, bit freezing, the hole of collapsing takes place in the extraction borehole work progress, also need write down azimuth, inclination angle, the drilling depth of boring and confirm the position that this abnormal conditions take place.In addition, because borehole engineering is recessive engineering, whether the degree of depth of construction drill adheres to specification, need carry out an acceptance inspection, and also need measure the degree of depth of boring.Because the coal bed drilling bed drain purge is big, uses triangular drilling rod to help the deslagging of holing, therefore, triangular drilling rod is more and more generally used in the construction of coal mine gas extraction borehole.If will understand the drilling depth of drilling, at present, the mode that the drilling rod radical multiply by single run of steel of creeping into that relies on mainly that driller writes down is calculated, and can not see the drilling depth value very clearly.
The utility model content
The purpose of the utility model provides a kind of drilling depth metering device, effectively solves the demonstration and the measurement problem of triangular drilling rod drilling depth.
To achieve these goals; The utility model comprises: balance cylinder, digital counting device, angular wheel, parallel travelling gear, flat thrust bearing, metering cylinder, upper semi-circle lid, lower half circle lid, compress pulley; Balance cylinder, digital counting device, metering cylinder are fixed in the upper semi-circle lid; Compressing pulley is fixed in the lower half circle lid; Flat thrust bearing is arranged on the two ends of upper semi-circle lid and lower half circle lid, and the rotating shaft with the digital counting device is connected the driving gear on the metering cylinder with angular wheel through parallel travelling gear successively.
Like this when triangular drilling rod drilling depth is measured; Round triangular drilling rod and locking, make metering cylinder, balance cylinder be close to triangular drilling rod pole face upper semi-circle lid, lower half circle lid, compress pulley and be close to triangular drilling rod corner angle; Flat thrust bearing and rig are close to; In the rod boring process, the upper semi-circle lid rotates round triangular drilling rod with the lower half circle lid, relies on frictional force metering cylinder when making circular motion, also to carry out axial rotation; The amount of the axially-movable of metering cylinder parallel drilling rod be exactly drilling rod at a time creep into length, promptly current drilling depth.Show through of the degree of depth metering of parallel travelling gear drive mechanical type digital counting device then, can know the drilling depth of Hot work in progress at any time current boring.Have intuitive display, characteristics such as time saving and energy saving, easy to use.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done further explain.
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the A-A cross-sectional schematic of the structural representation of the utility model.
The specific embodiment
Can know that by Fig. 1, Fig. 2 the utility model comprises: balance cylinder 1, digital counting device 2, angular wheel 3, parallel travelling gear 4, flat thrust bearing 6, metering cylinder 8, upper semi-circle lid 9, lower half circle lid 10, compress pulley 12.Balance cylinder 1, digital counting device 2, metering cylinder 8 are fixed in the upper semi-circle lid 9, and balance cylinder and metering cylinder are by the 13 secured in parallel settings of cylinder fixed mount, and the digital counting device is fixed in the centre of the two.Compressing pulley 12 is fixed in the lower half circle lid 10 by pulley fixed frame 11.Two flat thrust bearings 6 are separately positioned on the two ends of upper semi-circle lid and lower half circle lid, rotate flexibly to guarantee to be installed in when measuring on the triangular drilling rod 7.Rotating shaft with digital counting device 2 is connected driving gear 5 on the metering cylinder 8 with angular wheel 3 through parallel travelling gear 4 successively.For guaranteeing accurate measurement, carry out Precision Machining to the metering cylinder, through adjusting the gear ratio of parallel travelling gear, the digital counting device is shown the degree of depth metering of current boring.During use with upper semi-circle lid 9 and lower half circle lid 10 round triangular drilling rod 7 and locking, make metering cylinder, balance cylinder be close to triangular drilling rod pole face, compress pulley and be close to triangular drilling rod corner angle, flat thrust bearing and rig are close to and are got final product.
