Description
Technical field
The utility model belongs to the colliery and uses the safe production equipment field, relates in particular to a kind of colliery rigs against outburst.
Background technology
Existing mine mainly comprises gadder with rig, the slewing equipment assembly is set on the gadder, level is provided with guide rail on gadder, the slewing equipment assembly is positioned on the guide rail and with guide rail and is slidingly connected, the slewing equipment assembly comprises and is used to promote the propulsion plant that rig slewing equipment assembly reciprocatingly slides, the whirligig that is used to clamp the clamping device of drilling rod and is used to drive the clamping device rotation, described propulsion plant, clamping device and whirligig provide power by dynamical system, on guide rail, also be provided for the clamper of supports drill rods, by the slewing equipment assembly drilling rod is squeezed in the wall of coal seam during use, drilling rod is assisted the location by drill pipe clamp, be fixedly clamped drilling rod and drive the drilling rod rotary drilling of slewing equipment assembly in boring procedure, the slewing equipment assembly endwisely slips along guide rail with drilling rod simultaneously, after creeping into a certain progress the slewing equipment assembly along lead rail axis to returning certain distance, clamp another root drilling rod again and drive its rotary drilling, repeat above-mentioned action.Drilling rod is driven by the slewing equipment assembly and screws in the wall of coal seam, and by the reciprocating motion of slewing equipment assembly, thereby the standard operation drilling rod of equal length is squeezed in the wall of coal seam one by one, realizes the boring purpose.In the time the standard operation drilling rod in the coal seam wall boring need being taken out, again by the slewing equipment assembly with drilling rod extraction one by one, then depth survey is carried out in the boring of boring.But there is certain pressure in hole wall during because hole, after drilling rod is taken out from boring, the as easy as rolling off a log hole of collapsing that occurs of holing, thereby cause boring to stop up, the detector that be used to measure hole depth this moment can't accurately measure drilling depth, and the normal crooked or outstanding accuracy of measurement that also can have influence on detector that occurs makes the staff can't know drilling depth accurately, thereby impacts to ordinary production in the boring.The depth relationship of boring is to the gas drainage under suction effect, if can not accurately detect drilling depth, impact not only can for follow-up gas drainage under suction and coal-bed flooding etc., also can bring potential serious hidden danger directly for the Safety of Coal Mine Production in later stage, thereby impact to safety in production, it is significant for mine safety production therefore accurately to measure drilling depth.
The utility model content
The purpose of this utility model provides a kind of colliery rigs against outburst, to solve the technical problem that can't accurately measure drilling depth in the prior art.
For achieving the above object, the utility model adopts following technical scheme: a kind of colliery rigs against outburst, comprise gadder, gadder is provided with the slewing equipment assembly, the slewing equipment assembly moves reciprocatingly on gadder, described colliery with rigs against outburst be provided be used to detect the slewing equipment assembly move back and forth number of times near switch, should near switch be arranged on the gadder or be arranged on the support that is independent of outside the gadder with slewing equipment assembly limit of sports record position near the opposite position place, this signal output part near switch is connected with counting circuit by transmission line.
Described is inductance approach switch or capacitive approach switch near switch.
Described slewing equipment assembly comprises propulsion plant, clamping device and the whirligig that is driven by dynamical system, dynamical system is provided with and is used to second sensor that detects the first sensor of propulsion plant duty and/or be used to detect the whirligig duty, and the signal output part of the first sensor and second sensor is connected with data handling system.
Described dynamical system adopts hydraulic power, and propulsion plant is connected on the hydraulic power unit by different fluid pressure lines with whirligig, and the described first sensor and second sensor are the pressure sensor that is separately positioned on the corresponding fluid pressure line.
Described dynamical system adopts electric power, and dynamical system comprises the access cable that links to each other with whirligig with propulsion plant, and the described first sensor and second sensor are to be arranged on current sensor that is used for sensed current signal and/or the power sensor that inserts on the cable.
The colliery is provided with the reciprocating motion number of times that detects the slewing equipment assembly near switch with adopting on the rigs against outburst in the utility model on gadder, because drilling rod all adopts the standard drilling rod of equal length, and a drilling rod is once squeezed in the reciprocating motion of slewing equipment assembly, therefore the full-length that measured slewing equipment reciprocating motion number of times be multiply by drilling rod can draw the degree of depth of boring, thereby realizes the accurate measurement to hole depth.The utility model is simple in structure, convenient and practical, because employing heed contacted measure, its long service life, safe, fault rate is low, in boring, realize detection, avoided having guaranteed mine safety production owing to the bending owing to drilling rod in landslide of holing or the boring procedure causes hole deviation can't detect the difficult problem of hole depth after boring to hole depth.
