본 발명은 암반파쇄기용 유압승압장치에 관한 것으로, 더욱 상세하게는 구성이 간단하여 제작이 간편하고 제작비용이 적게 들며 사용이 편리함은 기본이고 전방에 암반파쇄공구가 연계설치되는 제1유압실린더의 후방에 제2유압실린더를 일체형으로 결합하고, 이들과 연계설치된 유압공급장치를 이용하여 유압을 공급하되,The present invention relates to a hydraulic pressure boosting device for a rock crusher, and more particularly, to a hydraulic pressure boosting device for a rock crusher, and more particularly, to a hydraulic pressure boosting device for a rock crusher having a first hydraulic cylinder A second hydraulic cylinder is integrally coupled to the rear side, and a hydraulic pressure is supplied by using a hydraulic pressure supply device provided in association with the second hydraulic cylinder,

일반적으로는 제1유압실린더에만 유압을 공급하여 소정의 작업을 수행하고 제1유압실린더에 작용하는 유압의 힘 만으로는 소정의 작업을 수행하기 어렵거나 보다 빠른 시간내에 작업 수행하고자 할 필요가 있을 경우에는 필요에 따라 제2유압실린더에 유압을 공급하여 유압을 승압시켜 제1실린더를 통해 보다 강력한 힘으로 소정의 작업을 보다 간편하고 신속하며 완벽하게 수행할 수 있도록 할 수 있는 암반파쇄기용 유압승압장치에 관한 것이다.In general, when it is necessary to perform a predetermined operation by supplying the hydraulic pressure to only the first hydraulic cylinder and to perform the predetermined operation only by the hydraulic pressure acting on the first hydraulic cylinder or to perform the operation within a shorter time A hydraulic pressure boosting device for a rock crusher which can pressurize the hydraulic pressure to the second hydraulic cylinder according to need so that a predetermined operation can be performed more simply, quickly and completely through the first cylinder through a stronger force .

일반적으로 공기압 보다 큰 작동력을 요구하는 암반파쇄기, 점보드릴, 전선압착기 등의 각종 유압공구는 주로 유압을 사용하게 된다.Generally, various hydraulic tools such as a rock crusher, a jumbo drill, and a wire compression machine, which require an operating force greater than air pressure, mainly use hydraulic pressure.

이와 같은 유압공구는 유압펌프에서 공급되는 유압에 의해 작동시키는 것으로, 상기 유압공구의 작동력을 더욱 극대화하기 위해서는 별도의 승압장치에 의해 유압을 승압시켜 사용하게 되는 것이다.Such a hydraulic tool is operated by hydraulic pressure supplied from a hydraulic pump. In order to maximize the operating force of the hydraulic tool, the hydraulic pressure is boosted by a separate booster.

이와 같은 종래 유압승압장치는 특허등록 제10-256084호에서 보는 바와 같이 유압펌프로 공급되는 유압을 피스톤 펌핑 작동에 의해 승압된 상태로 공급 사용하게 되는데, 이와 같은 종래 유압 승압장치는 단순한 피스톤 펌핑 등의 방법으로 승압작동하기 때문에 승압 효율이 떨어지는 단점이 있었다.In the conventional hydraulic pressure boosting device, as shown in Patent Registration No. 10-256084, the hydraulic pressure supplied to the hydraulic pump is supplied in a state of being boosted by a piston pumping operation. Such a conventional hydraulic pressure boosting device uses a simple piston pumping There is a disadvantage that the step-up efficiency is lowered.

즉, 상기한 종래 유압 승압장치는 유압의 승압을 높이기 위해서 장치 사이즈를 크게 만들어야 하기 때문에 경제성은 물론 휴대, 취급의 불편함을 초래하는 등의 여러 문제점이 있었다.That is, the conventional hydraulic pressure booster described above has various problems such as not only economical efficiency but also inconvenience of carrying and handling since the apparatus size must be made large in order to increase the pressure increase of the hydraulic pressure.

한편, 또 다른 유압승압장치로는 특허공개번호 제10-2011-0109427호에서 보븐 바와 같이 유압공급구와, 회수구를 갖는 상부몸체와, 중앙몸체와, 유압을 승압시켜 토출하는 토출구를 갖는 하부몸체를 긴 볼트로 상호 체결 조립 구성하되, 상기 상부, 중앙 및 하부몸체에는 내부에 유체의 공급, 회수를 위한 유로를 관통 연결되게 형성하고, 상기 공급구와 연결된 유로, 토출구와 연결된 유로 및 그 밖의 유로 위치로 체크 밸브 형태의 승압 밸브를 적어도 하나 이상 설치하여, 공급구를 통해 공급되는 유압이 승압 밸브를 통과하며 단계적으로 승압되어 토출구로 토출됨은 물론,On the other hand, another hydraulic pressure boosting device is disclosed in Patent Publication No. 10-2011-0109427, as an example of a boiler, an upper body having a hydraulic pressure supply port and a recovery port, a central body, and a lower body having a discharge port for discharging the hydraulic pressure, The upper, middle, and lower bodies are formed with a flow path for supplying and recovering fluid therein, and a flow path connected to the supply port, a flow path connected to the discharge port, and other flow path positions At least one check valve type pressure-up valve is installed, the hydraulic pressure supplied through the supply port is stepped up by the pressure-increasing valve, and is discharged to the discharge port,

공급구를 통해 공급되는 유압의 차단으로 승압밸브가 해제되어 유체가 회수구로 자동 회수하도록 한 것이다.The pressurizing valve is released by the interruption of the hydraulic pressure supplied through the supply port, so that the fluid is automatically recovered to the recovery port.

그러나, 이와 같은 후자의 유압승압장치는 그 구성이 매우 복잡하여 제작이 어렵고, 제작비용이 많이 들며, 사용상의 불편함이 많았다.However, the latter hydraulic pressure boosting device has a complicated construction, which makes it difficult to manufacture, requires a lot of manufacturing cost, and is inconvenient to use.

본 발명은 상기와 같은 종래 기술의 제반 문제점을 감안하여 안출한 것으로, The present invention has been made in view of the above-mentioned problems of the prior art,

일반적으로는 제1유압실린더에만 유압을 공급하여 소정의 작업을 수행하고 제1유압실린더에 작용하는 유압의 힘만으로는 소정의 작업을 수행하기 어렵거나 보다 빠른 시간내에 작업 수행하고자 할 필요가 있을 경우에는 필요에 따라 유압을 승압시켜 보다 강력한 힘으로 소정의 작업을 보다 간편하고 신속하며 완벽하게 수행할 수 있도록 할 수 있도록 하여 주고자 함에 그 목적을 둔 것이다. In general, when it is necessary to perform a predetermined operation by supplying the hydraulic pressure to only the first hydraulic cylinder and to perform the predetermined operation only by the hydraulic pressure acting on the first hydraulic cylinder or to perform the operation within a shorter time The present invention aims to increase the hydraulic pressure as needed so that a predetermined operation can be performed more simply, quickly, and completely with more powerful force.

본 발명의 암반파쇄기용 유압승압장치는 전방에 암반파쇄공구가 연계설치되는 제1유압실린더의 후방에 제2유압실린더를 일체형으로 결합하고, 이들과 연계설치된 유압공급장치를 이용하여 유압을 공급하되 필요에 따라 보다 승압된 강력한 유압력을 발생시켜 보다 수월하게 소정의 작업을 수행할 수 있도록 함에 그 특징이 있는 것이다.The hydraulic pressure boosting device for a rock breaking machine according to the present invention integrally couples a second hydraulic cylinder to the rear of a first hydraulic cylinder in which a rock crushing tool is installed in a front side and supplies hydraulic pressure using a hydraulic pressure supply device provided in association with the second hydraulic cylinder, It is possible to perform a predetermined operation more easily by generating a stronger hydraulic pressure which is boosted as needed.

이에 이와 같은 특징을 가지는 본 발명의 암반파쇄기용 유압승압장치를 첨부도면 도 1 내지 도 3에 의거 설명한다.The hydraulic pressure booster for a rock crusher according to the present invention having the above-described features will be described with reference to FIGS. 1 to 3. FIG.

본 발명의 암반파쇄기용 유압승압장치는 유압을 공급받아 전,후 작동하며 제1피스톤로드(121)가 전방을 향해 있는 제1피스톤(120)이 구비되는 제1챔버(110)가 형성된 제1유압실린더(100)의 후방에 역시 유압을 공급받아 전,후 작동하는 제2피스톤(220) 및 제2피스톤로드(221)가 구비되는 제2챔버(210)가 형성된 제2유압실린더(200)가 일체형으로 결합되어 있다.The hydraulic pressure boosting device for a rock crusher according to the present invention includes a first chamber 110 in which a first piston 120 having a first piston 120, A second hydraulic cylinder 200 having a second chamber 210 provided with a second piston 220 and a second piston rod 221 which are operated in the forward and backward directions with hydraulic pressure supplied to the rear of the hydraulic cylinder 100, Are integrally coupled.

또한, 이들 제1유압실린더(100) 및 제2유압실린더(200)는 유압펌프가 구비된 유압공급장치(300)와 연계설치되어 있어서, 상기 제1유압실린더(100)의 제1피스톤로드(121) 선단에 암반파쇄공구(11)를 연계설치한 다음 유압공급장치(300)를 이용하여 우선적으로 제1유압실린더(100)에 유압을 공급하여 소정의 작업을 진행하되 유압력이 부족할 경우에는 제2유압실린더(200)에 유압을 공급하여 승압된 유압이 제1유압실린더(100)를 통해 보다 큰 유압력으로 작업을 진행할 수 있도록 이루어져 있다.The first hydraulic cylinder 100 and the second hydraulic cylinder 200 are provided in connection with the hydraulic pressure supply device 300 having the hydraulic pump so that the first piston rod of the first hydraulic cylinder 100 121 and the rock crushing tool 11 are connected to each other and then hydraulic pressure is firstly supplied to the first hydraulic cylinder 100 by using the hydraulic pressure supply device 300. When the hydraulic pressure is insufficient, The hydraulic pressure is supplied to the second hydraulic cylinder 200 so that the boosted hydraulic pressure can be advanced through the first hydraulic cylinder 100 to a higher hydraulic pressure.

여기서 상기 유압공급장치(300)는 제1유압실린더(100) 및 제2유압실린더(200)와 수동 또는 자동으로 작동하는 유압제어밸브(310)와 각각 유압라인(301)(302)(303)(304)으로 연결되어 있고, 상기 제1유압실린더(100)의 유압라인(301)에는 역류방지밸브(330)가 더 설치되어 있다.The hydraulic pressure supply apparatus 300 includes a first hydraulic cylinder 100 and a second hydraulic cylinder 200 and a hydraulic control valve 310 and a hydraulic line 301, And a reverse flow prevention valve 330 is further provided on the hydraulic line 301 of the first hydraulic cylinder 100.

따라서, 제1실린더에 유압을 공급한 상태에서 제2유압실린더(200)에 유압을 공급하면 유압이 승압됨에 따라 제1챔버(110)의 오일이 유압라인(301)을 통해 역류하지 못하도록 이루어져 있다.Accordingly, when the hydraulic pressure is supplied to the second hydraulic cylinder 200 in the state where the hydraulic pressure is supplied to the first cylinder, the oil in the first chamber 110 can not flow back through the hydraulic line 301 as the hydraulic pressure is increased .

이번에는 상기와 같이 구성으로 이루어지는 본 발명의 암반파쇄기용 유압승압장치를 구성하는 제1유압실린더(100)의 제1챔버(110)에 구비된 제1피스톤(120)의 제1피스톤로드(121) 선단에 암반파쇄공구(11)를 설치하여 이를 암반파쇄작업을 수행하는 것을 일실시예로 하여 작동상태를 설명한다.The first piston rod 120 of the first piston 120 provided in the first chamber 110 of the first hydraulic cylinder 100 constituting the hydraulic pressure boosting device for a rock crusher according to the present invention having the above- The rock crushing tool 11 is provided at the tip of the rock crushing tool 11 to perform the rock crushing operation.

암반파쇄작업을 수행하기 위해서는 천공장비를 이용하여 암반(1)에 암반파쇄공구(11)가 삽입 가능한 크기로 다수의 천공홀(1a)을 서로 근접되게 천공한 다음,In order to perform the rock breaking operation, a plurality of perforation holes 1a are made to be close to each other so that the rock crushing tool 11 can be inserted into the rock block 1 using a perforating machine,

상기 천공홀(1a)에 본 발명 암반파쇄공구(11)를 삽입하고 유압공급장치(300)를 구성하는 유압펌프를 작동시키되 상기 유압제어밸브(310)를 제어하여 유압라인(301)을 통해 우선적으로 제1유압실린더(100)의 제1챔버(110)에 유압을 공급한다.The rock breaking tool 11 of the present invention is inserted into the perforation hole 1a and the hydraulic pump constituting the hydraulic pressure supply device 300 is operated to control the hydraulic pressure control valve 310 so that the hydraulic pressure is controlled via the hydraulic line 301 To the first chamber (110) of the first hydraulic cylinder (100).

그러면 제1피스톤(120)이 전진하면서 제1피스톤로드(121) 선단에 연계설치한 장대쐐기(11a)가 전진하게 되고 이에 따라 확장편(11b)이 확장되면서 암반(1)을 파쇄하게 된다.As the first piston 120 moves forward, the rod wedge 11a connected to the tip of the first piston rod 121 advances, and the rocking piece 1 is crushed by expanding the extending piece 11b.

이때, 상기 제1피스톤(120)에 작용하는 유압의 힘만으로는 암반(1)을 파쇄하는 힘이 부족할 경우에는 유압제어밸브(310)의 수동 또는 자동 제어에 의해 유압라인(303)을 통해 제2유압실린더(200)의 제2챔버(210)에 추가적으로 공급한다.At this time, when the force of crushing the rock mass 1 is insufficient only by the hydraulic pressure acting on the first piston 120, the hydraulic control valve 310 is manually or automatically controlled by the hydraulic line 303, To the second chamber (210) of the hydraulic cylinder (200).

그러면 상기 제2챔버(210)에 구비된 제2피스톤(220)이 전진하면서 제2피스톤로드(221)가 제1챔버(110)쪽으로 전진하게 된다. 그러면 파스칼의 원리에 의해 제2피스톤로드(221)의 단면적 비율만큼 보다 승압된 유압력이 제1챔버(110)에 발생하면서 강력한 힘으로 제1피스톤(120)을 푸쉬하게 된다.Then, the second piston 220 provided in the second chamber 210 advances and the second piston rod 221 advances toward the first chamber 110. Then, due to the Pascal principle, the first piston 110 pushes the first piston 120 with a strong force while the hydraulic pressure increased by the sectional area ratio of the second piston rod 221 is generated in the first chamber 110.

따라서, 제1피스톤로드(121) 선단에 연계설치한 장대쐐기(11a)가 더욱 강력한 힘으로 전진하게 되고 이에 따라 확장편(11b)이 확장되면서 유압이 약해 미쳐 파쇄되지 않던 암반(1)이 까지도 강력한 힘에 의해 손쉽게 파쇄된다.Therefore, the rod wedge 11a connected to the front end of the first piston rod 121 advances with a stronger force, and accordingly, the extended piece 11b is expanded, so that the rock mass 1, It is easily crushed by powerful force.

이때 상기 제1유압실린더(100)의 제1챔버(110)와 연결된 유압라인(301)에는 역류방지밸브(330)가 더 설치되어 있으므로 제2유압실린더(200)의 작동에 의해 강력한 유압의 힘이 작동하더라도 제1챔버(110)의 오일이 유압라인(301)을 통해 역류되는 것이 방지되므로 힘이 유압이 약해지지 않고 승압하는데 전혀 이상이 없다.At this time, the check valve 330 is additionally provided in the hydraulic line 301 connected to the first chamber 110 of the first hydraulic cylinder 100, so that the force of the strong hydraulic pressure The oil in the first chamber 110 is prevented from flowing back through the hydraulic line 301 so that the pressure does not rise at all without increasing the hydraulic pressure.

상기와 같은 본 발명의 유압승압장치는 구성이 간단하여 제작이 간편하고 제작비용이 적게 들며 사용이 편리하면서도 이를 암반파쇄공구(11)에 적용하여 사용하게 되면 필요에 따라 유압을 승압시켜 보다 강력한 힘으로 소정의 작업을 보다 간편하고 신속하며 완벽하게 수행할 수 있다.The above-described hydraulic pressure booster of the present invention is simple in construction, easy to manufacture, low in manufacturing cost, easy to use, and applied to the rock crushing tool 11 to increase the hydraulic pressure as needed, It is possible to perform a predetermined operation more simply, quickly, and completely.

이상과 같이, 본 발명은 비록 한정된 실시예와 도면에 의해 설명되었으나 이 실시예에 의해 한정되지 않으며, 본 발명이 속하는 기술 분야에서 통상의 지식을 가진 자에 의해 본 발명의 기술 사상과 아래에 기재될 특허청구범위의 균등범위 내에서 다양한 수정 및 변형 가능함은 물론이다.As described above, the present invention has been described by reference to the preferred embodiments and drawings, but it should be understood that the present invention is not limited to these embodiments, and various changes and modifications may be made without departing from the spirit and scope of the present invention by those skilled in the art.
