(54) БУРИЛЬНАЯ МАШИНА(54) DRILLING MACHINE

II

Изобретение отнеситс к горной промышленности , в частности к машинам дл бурени шпуров и скважин.The invention relates to the mining industry, in particular to machines for drilling holes and wells.

Известна бурильна машина, включаюша бурильную головку, буровой инструмент , основную и дополнительную, балки с винтами и гайками 1.A well-known boring machine, including a drill head, a main and auxiliary drilling tool, beams with screws and nuts 1.

Недостатком указанного устройства вл етс ограничение применени бурени по породам малой и средней крепости.The disadvantage of this device is to limit the use of drilling for rocks of small and medium strength.

Наиболее близкой к предлагаемой по тех нической суш1ностн и достигаемому результату вл етс бурильна машина, включающа ударник, жестко св занный со штоком силового цилиндра, в котором закреплена гайка с ВИНТОМ , установленным на опорах направл юшей, буровую штангу и распределитель 2.Closest to the proposed technical dryness and the achieved result is a boring machine, including a hammer, rigidly connected to a rod of a power cylinder, in which a nut is fixed with a SCREW, mounted on bearings, drill rod and a distributor 2.

Недостатками известной бурильной машины вл ютс сложность конструкции и низкий кпд.The disadvantages of the prior art drilling machine are the design complexity and low efficiency.

Цель изобретени - повышение КПД.The purpose of the invention is to increase efficiency.

Поставленна цель достигаетс тем, что машина снабжена мультипликатором с ведушей и ведомой шестерн ми, при этом ведуща шестерн жестко закреплена на винте , а ведома св зана через буровую,и1тангу с распределителем ударника.The goal is achieved by the fact that the machine is equipped with a multiplier with a lead and driven gear, while the driving gear is rigidly fixed to the screw, and the knowledge is connected through the drilling and tangent to the hammer distributor.

На чертеже изображено предлагаемое устройство, общий вид.The drawing shows the proposed device, a General view.

Бурильна машина включает ударник 1, установленный на направл ющей 2 и жестко 5 св занный со сштоком 3 силового цилиндра 4. На штоке 3 жестко закреплена гайка 5 (например, шариковинтова ), св занна с винтом 6, установленным на направл ющей 2 с помощью наружных опор 7. На винте 6 жестко закреплена ведуща шестерн 8 The boring machine includes a hammer 1 mounted on guide 2 and rigidly 5 connected to rod 3 of a power cylinder 4. A nut 5 (for example, a ball screw) fixed to screw 2 mounted on guide 2 is rigidly fixed to the rod 3 the support 7. On the screw 6 is fixed gear pinion 8

10 мультипликатора 9, ведома шестерн ip которого св зана с буровой штангой 11, установленной в хвостовике распределител 12 ударника 1 с бойком 13. Силовой цилиндр 5 имеет полости 14 и 15.10 of a multiplier 9, the gear of which ip is connected with a drill rod 11 installed in the shank of the distributor 12 of the striker 1 with a die 13. The power cylinder 5 has cavities 14 and 15.

Claims

Under the action of the forces developed by the pressure 15 in the cavity 14 of the cylinder 4, the rod 3 moves towards the bottom, thrust — the hammer 2 rigidly connected with it along the guide 2. The translational movement of the rod 3 with the nut 5 fixed in it turns into rotational movement of the screw 6. Rotation from the screw 6, through the drive pinhole 8 and the driven gear 10 of the multiplier 9 is transmitted to the drill rod 11 and the valve 12 of the striker I with a striker short circuit. As the distributor 12 rotates, the direction of flow of the working fluid in the striker 1 is redistributed and the striker 13 reciprocates, respectively, the angle of rotation of the drill rod II and the feed rate. When the hammer 1 is disconnected from the power source, the drilling will be rotary. The multiplier and screw transmission, kinematically linking the stem of the striker feeder with its distributor, eliminates the need for two special rotators on the feed mechanism and in the rotary hammer, which greatly simplifies the design, allows the device to operate in shock-rotational and rotational modes. Rigid fixing of the stem of the feeder with a hammer and the kinematic connection of the current with the drill rod and the distributor of the hammer allows to provide a certain feed and number of blows per Turn of the drilling tool, which makes it possible to designate the optimum ratio of these magnitudes and, consequently, increase the machine efficiency. Claims of the Invention A boring machine, including a hammer, rigidly connected with a rod of a power cylinder, in which a nut is fixed with a screw mounted on a guide support, a drill rod and a distributor, which, for the purpose of increasing efficiency, is equipped with a multiplier with a drive shaft. and the driven gear, while the gear is rigidly fixed to the screw, and the knowledge is connected through the drill rod to the drum distributor, Sources of Information.
