Description
Technical field
The utility model relates to the pressure tester that uses under a kind of mine, specifically a kind of drilling cuttings pressure tester.
Background technology
Trouble free service under the mine is very important, in order to guarantee the down-hole construction safety, can gather various data and carry out analysis and judgement, the data class of gathering is more many, the result who measures is just more accurate, can adopt boring method to measure coal-bed gas concentration generally speaking, with the drilling cuttings method work plane is impacted tendency and the detection of shock hazard degree, need boring in the time of drilling cuttings, drill bit can be sensed the stress of coal and rock in boring, if can will provide more reliable assurance for the trouble free service of down-hole with this data acquisition, but present rig does not also have this function.
The utility model content
In order to address the above problem, the utility model proposes a kind of drilling cuttings pressure tester, this device not only can obtain drilling cuttings, and can collect the stress of coal and rock, for the trouble free service of down-hole provides reliable guarantee foundation.
The technical scheme that its technical problem that solves the utility model adopts is: this a kind of drilling cuttings pressure tester, comprise drilling rod, rig, A/D converter, pressure analyzer, display, data-interface, memory and pressure sensor, the front end of described drilling rod is provided with a pressure sensor; The hull outside of described rig is provided with display and data-interface, is provided with A/D converter, pressure analyzer and memory in the housing of rig; Described A/D converter is connected with pressure sensor; Described pressure analyzer is connected with memory, display and A/D converter respectively; Described memory is connected with data-interface.
The beneficial effects of the utility model are: this a kind of drilling cuttings pressure tester is simple in structure, practical and convenient, not only drilling cuttings can be obtained, and the stress of coal and rock can be collected, improved the accuracy of risk prediction, for the trouble free service of down-hole provides reliable guarantee foundation.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Accompanying drawing 1 is the example structure schematic diagram of this a kind of drilling cuttings pressure tester.
Among the figure, 1. drilling rod, 2. rig, 3.A/D converter, 4. pressure analyzer, 5. display, 6. data-interface, 7. memory, 8. pressure sensor.
The specific embodiment
In accompanying drawing 1, this a kind of drilling cuttings pressure tester comprises drilling rod 1, rig 2, A/D converter 3, pressure analyzer 4, display 5, data-interface 6, memory 7 and pressure sensor 8, and the front end of described drilling rod 1 is provided with a pressure sensor 8; The hull outside of described rig 2 is provided with display 5 and data-interface 6, is provided with A/D converter 3, pressure analyzer 4 and memory 7 in the housing of rig 2; Described A/D converter 3 is connected with pressure sensor 8; Described pressure analyzer 4 is connected with memory 7, display 5 and A/D converter 3 respectively; Described memory 7 is connected with data-interface 6.
A/D converter 3, pressure analyzer 4, display 5, memory 7 and pressure sensor 8 all are connected with the power supply of rig 2, and a battery can also be set, for above each parts provide operating voltage.
In the process of drilling cuttings, pressure sensor 8 is passed to A/D converter 3 with the stress in coal seam, A/D converter 3 becomes data signal to pass to pressure analyzer 4 data transaction of receiving, pressure analyzer 4 is passed to display 5 with analysis result and is shown, and pass to memory 7 storage, can data output be preserved or give the related personnel and analyze by data-interface 6.
