Abstract
The utility model discloses a mining shaft boring machine, including the well drilling head, the first rear portion of well drilling is provided with pressure device, pressure device includes the power post, the inside pneumatic cylinder that is provided with of power post, the inside piston rod that is provided with of pneumatic cylinder, the pneumatic cylinder is inside to be provided with two pressure regulating pieces, is provided with the pressure regulating hole on the pressure regulating piece, the toper that the middle part of piston rod reduces for the diameter gradually, be provided with the liquid hole between piston rod and the pressure regulating piece. The utility model has the advantages of prior art's drawback, the reasonable novelty of structural design can be overcome to it. Compared with the prior art, the utility model have and to know presser operating condition's advantage in the pit on ground to for the operator bring the convenience, really play invariable pressor effect. Simultaneously, this presser simple structure, the ground control is easy. The resistance of marcing can be learnt through detecting hydraulic pressure to liquid hole excessively and setting up of pressure regulating hole through hydraulic means to know presser operating condition in the pit.
Description
Technical field
The utility model relates to a kind of mining drilling equipment, belongs to winning equipment field.
Background technology
Conventional hydraulic pressurizer of the prior art, is made up of drill string, joint, piston, cylinder barrel, piston rod, splined and drill bit. The Pressure Drop that its operation principle forms while mainly leaning on drilling fluid by bit nozzle, produces thrust at piston upper surface. This thrust be the pressure of the drill being delivered on drill bit. Impulse stroke is exactly the length that piston is axially migrated in cylinder barrel. The pressurizer of this structure only, in the time that piston does not contact joint, just plays the effect of constant pressurization, in the time of piston contact joint, continues to transfer drill string, will on drill bit, form excessive pressure, causes drill bit to damage too early. In addition, because this pressurizer ground does not have display unit, driller is difficult to grasp down-hole situation, whether down-hole pressurizer adds presses ground to know. Thereby, no matter from operating, still using above, conventional hydraulic pressurizer all exists major defect.
Utility model content
The deficiency existing for prior art, technical problem to be solved in the utility model is, a kind of mining drilling equipment is provided, and has enough plasticity and toughness and highly corrosion resistant.
For solving the problems of the technologies described above, the technical scheme that the utility model is taked is, a kind of mining drilling equipment, comprise drilling well head, drilling well back of head is provided with pressue device, and described pressue device comprises power post, power post inside is provided with hydraulic cylinder, and hydraulic cylinder inside is provided with piston rod; Described hydraulic cylinder inside is provided with two pressure regulation sheets, on pressure regulation sheet, is provided with regulator hole; The middle part of described piston rod is the taper that diameter reduces gradually; Between described piston rod and pressure regulation sheet, be provided with liquid pass hole; Described pressue device rear portion is provided with liquid-jet device, and the top of drilling well head is provided with spray hole; Described drilling well head and pressue device are rotationally connected by connecting cylinder, and connecting cylinder is socketed on pressue device outside, and the rear portion of connecting cylinder is provided with spline; Described liquid-jet device comprises a middle receiver, and middle receiver connects spray hole by sparge pipe; In the middle of described, between receiver and jet head, be provided with a force (forcing) pump.
Optimize, above-mentioned mining drilling equipment, is provided with pressure regulator valve on described regulator hole.
The utility model has the advantage of that it can overcome the drawback of prior art, reasonable in design novelty. The utility model compared with prior art has advantages of can be in understanding down-hole, ground pressurizer duty, thereby brings convenience to operator, really plays the effect of constant pressurization. Meanwhile, this pressurizer is simple in structure, and ground monitoring is easy. Liquid pass hole and arranging of regulator hole by hydraulic means can be learnt running resistance by detecting hydraulic pressure, thereby understand down-hole pressurizer duty.
Brief description of the drawings
