Description
Technical field
The utility model belongs to coal mine down-hole drilling depth survey technical field.
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.When boring began to construct, its azimuth, inclination angle just confirmed to have only drilling depth constantly changing.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.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 drilling depth.
To achieve these goals; The utility model comprises: digital counting device, housing, the tight cylinder of leveler piezometric, vertical auxiliary cylinder, auxiliary cylinder, wear-resisting ball, the base of compressing in diagonal angle of compressing; The digital counting device is fixedly installed on the housing internal upper part; Wear-resisting ball is arranged on bottom in the housing; Contact is provided with the tight cylinder of leveler piezometric on wear-resisting ball top, contacts respectively in wear-resisting ball middle and lower part to be provided with the vertically auxiliary auxiliary cylinder that compresses of cylinder and diagonal angle that compresses, and the tight cylindrical rotating shaft of leveler piezometric is connected with the rotating shaft of digital counting device through travelling gear.
Like this when drilling depth is measured; Utilize base that the utility model is fixed on the drilling rod top, make wear-resisting ball be close to drilling rod, in the rod boring process; Relying on frictional force to drive wear-resisting ball rolls; Utilize the tight cylinder of leveler piezometric, vertically the auxiliary cylinder that compresses is transformed into two amounts of the parallel and vertical drilling rod direction of drilling rod with the rolling amount of ball, the amount of 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 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 operating principle sketch map of the utility model.
Fig. 2 is the structural representation of the utility model.
The specific embodiment
Can know by Fig. 1, Fig. 2; The utility model comprises: comprising: the tight cylinder of digital counting device 1, housing 7, leveler piezometric 2, vertical auxiliary cylinder 6, auxiliary cylinder 5, wear-resisting ball 4, the base 10 of compressing in diagonal angle of compressing, the tight cylinder of leveler piezometric, vertically auxiliaryly compress cylinder, the diagonal angle is auxiliary compresses cylinder by fixed mount 9 support fixation.Digital counting device 1 is fixedly installed on housing 7 internal upper parts, and wear-resisting ball 4 is arranged on bottom in the housing 7, has circular hole at the base middle part, contacts so that wear-resisting ball exposes with drilling rod 3.Contact is provided with the tight cylinder 2 of leveler piezometric on wear-resisting ball top; Contact respectively in wear-resisting ball middle and lower part and to be provided with vertically auxiliary cylinder 6 and the auxiliary cylinder 5 that compresses in diagonal angle of compressing, the rotating shaft of the tight cylinder 2 of leveler piezometric is connected with 1 rotating shaft of digital counting device through travelling gear 8.
For guaranteeing accurate measurement; To carry out Precision Machining to the tight cylinder of leveler piezometric and the wear-resisting ball of metering usefulness; After the measurement unit of the tight cylindrical girth of leveler piezometric that measures usefulness is confirmed; Regulate the metering of drilling depth, can be through adjusting the gear ratio of travelling gear, the digital counting device shows the degree of depth metering of current boring.Before the use, open chamber door by administrative staff, the digital counting device is returned zero, a rig disposes a drilling depth metering device, can know the drilling depth of Hot work in progress at any time.
