Description

Изобретение относитс к технологическому оборудованию горнодобывающей промьшшенности и может быть использовано при гидравлическом разрушении горных пород.The invention relates to the technological equipment of the mining industry and can be used in the hydraulic destruction of rocks.

Известен гидравлический повыситель давлени , включающий нагнетательный гидроцидиндр с плунжером, низконапорный гидроцилиндр с соплом, систему двухпозиционных распределителей и т гу с упорами 1.A hydraulic pressure booster is known, which includes an injection hydraulic cylinder with a plunger, a low-pressure hydraulic cylinder with a nozzle, a two-way valve system, and a rod with stops 1.

Недостатком данного гидравлического повысител давлени вл етс пульсаци жидкости в низконапорном трубопроводе из-за периодического открыти и закрыти сопла, что снижает надежность устройства в целом.The disadvantage of this hydraulic pressure booster is the pulsation of the fluid in the low pressure pipeline due to the periodic opening and closing of the nozzle, which reduces the reliability of the device as a whole.

Наиболее близким к предлагаемо1чу по технической сущности и достигаемому результату вл етс гидравлический повыситель давлени , включающий блок нагнетательных цилиндров, всасывающие и нагнетательные клапаны и систему привода 2.The closest to the proposed technical essence and the achieved result is a hydraulic pressure booster, including a block of pressure cylinders, suction and discharge valves, and a drive system 2.

Недостатком указанного гидравлического повысител давлени вл етс . наличие гидроударов в системе привода , котора , выполнена в виде сопел, рычагов и направл ющих патрубков. Гидравлические удары вызывают преждевременный износ гидравлических линий и гидроаппаратуры, снижают надежность всего устройства в целом.The disadvantage of this hydraulic pressure booster is. the presence of water hammer in the drive system, which is made in the form of nozzles, levers and guide tubes. Hydraulic shocks cause premature wear of hydraulic lines and hydraulic equipment, reducing the reliability of the entire device.

Цель изобретени - повыи1ение над зкности путем исключени гидравлических ударов .The purpose of the invention is to increase the viscosity by eliminating hydraulic shocks.

Указанна цель достигаетс тем, что система привода выполнена в виде сопел привода, шарниров, приводных This goal is achieved by the fact that the drive system is made in the form of drive nozzles, hinges, drive

10 валов с зубчатой передачей, толкателей и сопел управлени , причем сопла привода установлены в шарнирах и св заны друг с другом посредством приво.цных валов с зубчатой передачей, а There are 10 gear shafts, pushers and control nozzles, with the drive nozzles mounted in the hinges and connected to each other via gear shafts with a gear drive, and

15 сопла управлени жестко св заны между собой, установлены в шарнире и св заны с торцами плунжеров посредством толкателей, при этом сопла управлени смещены друг относительно друга на 15, the control nozzles are rigidly connected to each other, mounted in the hinge and connected to the ends of the plungers by means of pushers, while the control nozzles are offset relative to each other by

20 угол, равный углу их качани .20 angle equal to the angle of their swing.

Claims

25 includes a block of injection cylinders 1 with suction 2 and discharge 3 valves, a plunger 4 with points 5, a low pressure 6 and a high pressure 7 line, driving 30, which includes drive nozzles 8, hinges 9, drive shafts 10 with gears This transmission, pushers 12 and control 13 with rachags 14. A gear transmission 11 serves to synchronize the swing of the drive nozzles by means of drive shafts 10. The pushers 10 serve for the simultaneous swing of the control nozzles 13. Move the synchronously swinging nozzles of the drive 8 from one extreme position neither in another, their fixation in the required position is accomplished by exposing them to a jet of liquid emanating from the control nozzles 13. The hydraulic pressure booster works as follows. Through the suction valve 2, fluid is supplied to the chambers of the block of injection cylinders 1. At the same time, the pressurized fluid is supplied to the drive nozzles of the Viv control nozzle 13. From the right-hand drive nozzle, a jet of fluid flows through the pin 5 of the right upper plunger 4 - it together with the left upper plunger moves to the left. The C-Cfr fluid emanating from the left drive nozzle acts on the p 5 of the lower left plunger 4 and moves it together with the right lower plunger to the right. The fluid is displaced by the plungers 4 through the pressure valve 3 into the high pressure line 7. In this case, a jet of fluid emanating from the upper control nozzle acts on the actuator nozzle and holds it in the position indicated in FIG. 1 and 2. At the end of the stroke, the upper plunger 4 by means of the pusher 12 rotates the control nozzles 13 to the leftmost position. As a result, a jet of fluid flowing from the lower control nozzle acts on the actuator nozzle, with the result that the actuator nozzle is turned to another extreme position. By means of drive shafts 10 and gear 11, the right-hand drive nozzles are switched. After that, the upper left and right plungers 4 under the action of the jet flowing from the left drive nozzle, move to the right, and the left and right lower plungers 4., under the action of the jet flowing from the right drive nozzle, move to the left. Thus, the injection process is repeated. Practical use of the invention makes it possible to increase the reliability of hydraulic pressure increase by eliminating hydraulic shocks and thereby increasing the service life of the plungers, seals and the entire hydraulic system as a whole. Claim 1. Hydraulic pressure booster, switching block of injection cylinders with plungers, suction and discharge valves and drive system, characterized in that, in order to increase reliability by eliminating water hammer, the drive system is made in the form of right-side nozzles, hinges, drive shafts gear, pushers and control nozzles, with the drive nozzles mounted in the hinges and connected to each other via gear shafts to the gear drive, and the control nozzles are rigidly connected between each other, mounted in a hinge and connected to the ends of the plungers by means of tappets. In this case, the control nozzles are displaced relative to each other by an angle equal to the angle of their swing. Sources of information taken into account in the examination 1.
