본 고안은 콘크리트펌프의 절환밸브장치에 관한 것으로, 하방의 연통관과 연통하는 콘크리트홉퍼 하방의 2개의 흡입구에 교호로 개폐작동하는 절환밸브판을 사각으로 유설함과 동시에 연통관 일측에 설치된 콘크리트실린더와 대응하는 위치인 연통관의 타측에 연설된 토출관의 양지관 접합부내에 역시 개폐자재하는 개폐관을 유설하여 콘크리트 펌프의 콘크리트 이송작업을 원활하게 수행할 수 있도록 한 것이다.The present invention relates to a switching valve device of a concrete pump, and to the concrete cylinder installed on one side of the communication pipe while installing a switching valve plate alternately opening and closing to the two suction ports of the concrete hopper communicating with the communication pipe below. In order to smoothly carry out the concrete conveying work of the concrete pump, the opening and closing of the opening and closing pipes are also installed in the joint pipe joint of the discharge pipe, which is addressed to the other side of the communication pipe.

일반적으로 종래 콘크리트펌프의 절환밸브장치에 있어서는 제4도내지 제5도에 도시된 바와같이 콘크리트 홉퍼(a)에 접속하는 흡입구(b)와, 토출관(d)에 접속하는 토출구(c)를 상호 개폐시켜 줄수 있는 밸브체(e)를 배설하고 이 밸브체(e)를 슬라이드 로드(f)로 보지시켜서 왕복운동되게 하여 콘크리트의 흡입, 토출작업을 절환시켜 줄수 있는 방법의 구조를 채택하고 있었으나, 이는 제5도에 도시된 바와같이 2개의 콘크리트 실린더(g)를 교호로 작동시켜 콘크리트를 토출시킬때 토출관(d)의 양지관(d1)(d2)중 1개의 지관(d1)에서만 토출작용을 하가ㅔ 되어 토출되는 콘크리트가 양지관(d1)(d2)의 접합부인 토출관(d)선단으로 이동될때 콘크리트가 토출작업을 행하지 않은 일측지관(d2)내로 유입되어 충전되게 되어 비유동부(h)가 형성되며, 이 비유동부(h)의 콘크리트는 상기 지관(d1)의 유동압력을 받게 되며, 또한 이의 콘크리트중의 수분이 외부로 탈취되어 후속작업인 기관(d2)에서의 콘크리트 토출량이 적어지게 되는 등의 문제점이 있어 콘크리트의 흡인, 토출 효율이 저하되는 문제점이 있었다.In general, in the switching valve device of the conventional concrete pump, as shown in FIGS. 4 to 5, the inlet port b connected to the concrete hopper a and the discharge port c connected to the discharge pipe d are provided. Although the valve body (e) which can be opened and closed to each other is installed, the structure of the valve body (e) is held by the slide rod (f) to be reciprocated so that the suction and discharge of concrete can be switched. , which is 2 one of the two to the concrete works the cylinder (g) alternately note pipe of the discharge pipe (d) when discharging the concrete (d 1) (d 2) the branch pipe as shown in FIG. 5 (d 1 When the concrete is discharged only to the tip of the discharge pipe (d), which is the junction of the sunny pipe (d 1 ) (d 2 ), the concrete flows into the one branch pipe (d 2 ) where the discharge is not performed. The non-flow portion h is formed by filling the non-flow portion h. Concrete will receive the fluid pressure in the branch pipe (d 1), also the suction of the concrete there is a problem, such as the water component of its concrete is seized to the outside which the concrete flow rate at a subsequent operation the organ (d 2) becomes less There is a problem that the discharge efficiency is lowered.

본 고안은 종래의 이와같은 제반 문제점을 해소하기 위하여 콘크리트 홉퍼하부의 흡입구 하방이 사각으로 교호로 개폐가능하게 유설한 절환밸브판을 설치하여 콘크리트 실린더의 흡입, 토출작용에 의하여 절환밸브판이 개폐절환되도록 하여 콘크리트펌프의 절환밸브장치의 구조를 간단하게 구성하여 그 제작이나 보수가 용이하게 할 뿐만아니라, 콘크리트 토출시 토출관의 지관내로 콘크리트가 역류되는 현상을 방지하여 주어 콘크리트의 흡인작업과 토출작업능률을 향상시켜 줄수 있도록 한 것으로 이를 첨부한 도면에 의하여 상세히 설명하면 다음과 같다.The present invention provides a switching valve plate in which the lower side of the inlet of the lower portion of the concrete hopper can be alternately opened and closed alternately in order to solve such a conventional problem, so that the switching valve plate can be opened and closed by suction and discharge of the concrete cylinder. The simple structure of the switching valve device of the concrete pump makes it easy to manufacture and repair, and also prevents the flow of concrete back into the branch pipe of the discharge pipe during the concrete discharge. It will be described in detail by the accompanying drawings as to improve the following.

즉, 콘크리트 홉퍼(1)하부에 2개의 흡입구(2)(2')를 사향으로 형성하고, 이 하방에 연통관(3)(3')을 형성하여 이 연통관(3)(3')양측에 각각 콘크리트 실린더(4)(4')와 토출관(5)의 양지관(5')(5")을 접설한 공지의 것에 있어서, 흡입구(2)(2')하방에 절환밸브판(6)(7)을 핀(8)으로 관통시켜 사향으로 유설하고 이의 회전연장방향의 연통관(3)(3')내벽 상부에 괘지턱(9)(9')을 돌설한 다음, 토출관(5)의 양지관(5')(5")접합부에 개폐판(10)을 회동자재하게 유설하여서된 것으로, 미설명부호 11,11'는 콘크리트 실린더(4)(4')의 피스톤, 12는 교반익, 13은 교반익회전용 체인이다.That is, two suction ports 2, 2 'are formed under the concrete hopper 1 in a civet manner, and communication pipes 3, 3' are formed below the communication hoppers 3, 3 '. In the known ones in which the sunny cylinders 5 'and 5 "of the concrete cylinders 4 and 4' and the discharge pipe 5 are connected, respectively, the switching valve plate 6 under the inlet port 2 and 2 '. (7) penetrates through the pin (8) and is installed in the musk, and the projection (9) (9 ') is protruded on the inner wall of the communication tube (3) (3') in the direction of its extension, and then the discharge tube (5) The opening and closing plate 10 is rotatably installed at the joint pipe (5 ') (5 ") of the joint of the), and reference numerals 11 and 11' denote pistons of the concrete cylinders 4 and 4 ', and 12 The stirring blade 13 is a chain for stirring blade rotation.

이와같이 구성된 본 고안은 콘크리트믹서나 레미콘가(도시생략)에서 믹스된 콘크리트를 콘크리트 홉퍼(1)내로 주입하고 이 하부의 흡입구(2)(2')와 연통된 연통관(3)(3')의 일측에 설치된 콘크리트 실린더(4)(4')를 교호로 작동시켜주면 콘크리트 홉퍼(1)내의 콘크리트 실린더(4)(4')에 의하여 흡입, 토출되어 토출관(5)으로 토출되게 되는데, 이때 제2(b)도에 도시된 바와같이 콘크리트 실린더(4)의 피스톤(11')이 우측으로 이동하여 신축되면 이의 흡인력에 의하여 콘크리트 홉퍼(1)하부의 흡입구(2')하방에 사향으로 유설된 절환밸브판(7)이 개방되어 콘크리트 홉퍼(1)내의 콘크리트가 콘크리트 실린더(4')내부로 흡입됨과 동시 절환밸브판(7)은 연통관(3')내벽 상부에 돌설된 괘지턱(9')에 의하여 괘지되어 과다히 개방되는 현상이 방지되고, 타측 콘크리트 실린더(4")는 제2(a)도에 도시된 바와같이 피스톤(11)을 좌측으로 이동하여 신장되면서 앞 행정에서 흡입되어 있던 콘크리트를 압출시켜주면, 이 압출력에 의하여 이송되는 콘크리트가 괘지턱(9)에 괘지되어 개방되어 있던 절환밸브판(6)을 진행방향으로 압압하여 콘크리트 홉퍼(1)의 흡입구(2)를 폐쇄시켜 줌과 동시 콘크리트가 토출관(5)의 지관(5')를 통과하는 순간 이의 압출력에 의하여 토출관(5)의 양지관(5')(5")사이의 접합부에 유설된 개폐판(10)이 지관(5")측으로 이동하여 지관(5')을 개방하고 지관(5")을 폐쇄시켜 줌으로서 콘크리트 실린더(4)에 의하여 콘크리트 토출할때 토출되는 콘크리트가 지관(5")내로 역류되는 현상이 완벽하게 방지되어 콘크리트의 토출기능이 향상되는 것이다.The present invention configured in this way is to inject concrete mixed in the concrete mixer or ready-mixer (not shown) into the concrete hopper (1) and one side of the communication tube (3) (3 ') in communication with the lower inlet (2) (2') By alternately operating the concrete cylinder (4) (4 ') installed in the suction and discharge by the concrete cylinder (4) (4') in the concrete hopper (1) is discharged to the discharge pipe (5) As shown in FIG. 2 (b), when the piston 11 ′ of the concrete cylinder 4 moves to the right and is stretched, the suction force of the piston 11 ′ is lowered to the suction port 2 ′ under the concrete hopper 1 by its suction force. The switching valve plate 7 is opened so that the concrete in the concrete hopper 1 is sucked into the concrete cylinder 4 'and at the same time, the switching valve plate 7 is placed over the inner wall of the communication pipe 3'. Is prevented from being excessively open, and the other concrete cylinder (4 ") is prevented. As shown in FIG. 2 (a), when the piston 11 is moved to the left to extend and extrudes the concrete sucked in the front stroke, the concrete conveyed by this extrusion force hangs on the hanging jaw 9. Presses the open switching valve plate 6 in the advancing direction to close the inlet port 2 of the concrete hopper 1 and at the same time the concrete passes through the branch pipe 5 'of the discharge pipe 5 The opening and closing plate 10 held at the joint portion between the sunny pipes 5 'and 5 "of the discharge pipe 5 is moved to the paper pipe 5" side by the extrusion force to open the paper pipe 5' and open the paper pipe ( By closing the 5 "), the discharge of the concrete discharged when the concrete is discharged by the concrete cylinder 4 back into the branch pipe 5" is completely prevented and the discharge function of the concrete is improved.

이후 콘크리트 실린더(4)에서의 콘크리트 토출작업이 완료되면 상기와 반대로 콘크리트 실린더(4)(4')가 동작하여 연속적으로 콘크리트를 흡입, 토출시켜 주게 되는 것이다.After the concrete discharge operation in the concrete cylinder (4) is completed, the concrete cylinder (4) (4 ') is operated in reverse to the above to inhale, discharge the concrete continuously.

이와같은 본 고안은 별도의 절환밸브를 가동시켜주는 장치없이 기존 콘크리트 실린더의 콘크리트 흡입, 토출작용에 의하여 콘크리트 홉퍼의 밸브를 절환시켜 줄수 있어 콘크리트펌프의 구조를 대폭 간소화할 수 있을 뿐만 아니라, 콘크리트가 토출시 토출작업에 관계없는 일측지관을 폐쇄시켜 주어 콘크리트가 역류되는 현상을 방지하여 줄수 있게 되어 콘크리트의 토출기능을 향상시켜 줄수 있는 효과를 지닌 유용한 고안인 것이다.The present invention can switch the valve of the concrete hopper by the concrete suction and discharge action of the existing concrete cylinder without a device for operating a separate switching valve, thereby greatly simplifying the structure of the concrete pump, It is a useful design with the effect of improving the discharging function of concrete by closing the one branch pipe irrelevant to the discharging operation during discharging and preventing the backflow of concrete.
