콘크리트 펌프카의 잔류콘크리트 배출장치 및 방법{Rresidual concrete emission device of concrete pump car and method thereof}Residual concrete emission device of concrete pump car and method

본 발명은 콘크리트 펌프카에 관한 것으로, 보다 상세하게는 레미콘으로부터 호퍼로 공급되는 콘크리트가 호퍼로부터 압송관를 통해 타설 한 후, 호퍼 및 압송관에 잔류하는 콘크리트를 순간급수장치로 호퍼에 물을 공급하여 물과 혼합되어 호퍼 및 압송관에 잔존하는 잔류콘크리트를 레미콘으로 배출되도록 회수시켜, 콘크리트의 재활용이 가능하여 환경오염을 방지함과 아울러 세척시간을 줄여 작업효율성을 향상시킬 수 있는 콘크리트 펌프카의 잔류콘크리트 배출장치 및 방법에 관한 것이다.
The present invention relates to a concrete pump car, and more specifically, after the concrete supplied from the ready-mixed concrete to the hopper is poured from the hopper through the feed pipe, the concrete remaining in the hopper and the feed pipe is supplied with water to the hopper with an instantaneous water supply device to water And the residual concrete remaining in the hopper and the feed pipe to be discharged to the ready-mixed concrete, and the concrete can be recycled so that the concrete can be recycled to prevent environmental pollution and to reduce the cleaning time and improve the work efficiency. An apparatus and method are provided.

일반적으로 자갈과 모래, 시멘트 및 물을 일정비율로 혼합하여 건물의 지반이나 지주로 사용되는 콘크리트는 레미콘 차량을 통해 미경화 상태로 시공현장으로 투입된다.In general, concrete, which is used as a ground or a pillar of a building by mixing gravel, sand, cement, and water at a predetermined ratio, is input to the construction site in a uncured state through a ready-mixed concrete vehicle.

상기 시공현장이 건물의 지하벽면 이나 기둥일 경우, 레미콘 차량으로부터 콘크리트의 공급이 가능하나, 레미콘 차량보다 높은 고층건물의 벽면이나 기둥일 경우, 레미콘으로부터 공급되는 콘크리트가 전개된 붐대에 연결되어 있는 압송관을 통해 타설 현장에 직접 타설할 수 있는 콘크리트 펌프카가 이용된다.When the construction site is a basement wall or pillar of the building, it is possible to supply concrete from the ready-mixed vehicle, but when the wall or pillar of a high-rise building higher than the ready-mixed vehicle, the concrete supplied from the ready-mixed concrete is fed to a boom that is deployed. A concrete pump car is used that can be poured directly into the site of pouring through a pipe.

도 1에 도시된 바와 같이 상기 콘크리트 펌프카(10)는, 차량의 후단에 콘크리트를 투입하기 위한 호퍼(11)와, 상기 호퍼(11)에 투입된 콘크리트를 차량이 높이 조절이 가능한 붐대(12)에 고정되어 타설현장으로 이동하는 압송관(13)과, 상기 압송관(13) 끝단부에 고정되는 엔드호스(14)로 이루어져 있으며, 상기 호퍼(11)로 공급된 콘크리트는 실린더(15)의 펌핑으로 압송관(13)과 엔드호스(14)를 통해 현장에 타설된다.As shown in FIG. 1, the concrete pump car 10 includes a hopper 11 for injecting concrete into the rear end of the vehicle and a boom 12 for adjusting the height of the concrete injected into the hopper 11. It is composed of a feed pipe 13 is fixed to move to the pouring site, and the end hose 14 is fixed to the end of the feed pipe 13, the concrete supplied to the hopper 11 pumping the cylinder 15 It is poured into the site through the pressure pipe (13) and the end hose (14).

상기 콘크리트 펌프카를 통한 콘크리트의 타설이 완료되면, 실린더를 정지시켜 콘크리트의 공급을 중단하는데, 이때 호퍼와 압송관 및 엔드호스 내에 콘크리트가 잔류하게 되며, 잔류하는 콘크리트를 방치할 경우, 호퍼와 압송관 및 엔드호스 내에서 굳어져 내부가 막히므로 즉시 호퍼와 압송관 및 엔드호스 내부에 잔류한 콘크리트는 반드시 제거해야 된다.When the casting of concrete through the concrete pump car is completed, the supply of concrete is stopped by stopping the cylinder. At this time, the concrete remains in the hopper, the pressure pipe and the end hose, and when the remaining concrete is left, the hopper and the pressure pipe And the inside of the end hose is clogged and the inside is blocked, so concrete remaining inside the hopper, the pressure pipe and the end hose must be removed.

상기의 문제점을 해결하기 위해 근래에는 엔드호스 내부로 탄력부재의 부압볼을 삽입한 후, 실린더를 역방향으로 가동하여 그에 따른 부압으로 부압볼을 이동시킴과 동시에 부압볼에 의해 엔드호스와 압송관 내부의 콘크리트가 호퍼로 회수한 후, 호퍼의 게이트를 개방하여 폐기 처리하였다.In order to solve the above problems, in recent years, after inserting the negative pressure ball of the elastic member into the end hose, the cylinder is operated in the reverse direction to move the negative pressure ball to the negative pressure accordingly, and at the same time by the negative pressure ball inside the end hose and the pressure feed pipe After the concrete was recovered into the hopper, the gate of the hopper was opened and disposed of.

상기 부압볼을 이용한 콘크리트 처리방식은, 호퍼로 회수된 콘크리트가 게이트를 통해 폐기처리하므로 자원의 낭비에 따라 경제적 손실이 발생함과 아울러 환경을 오염시키는 문제점이 있었다.In the concrete treatment method using the negative pressure ball, since the concrete recovered by the hopper is disposed of through the gate, there is a problem in that an economic loss occurs and pollution of the environment according to waste of resources.

또한, 실린더를 역방향으로 가동하여 부압볼을 흡입 시 흡입률이 저하됨에 따라 작업시간이 늘어나는 문제점이 있었다.
In addition, there is a problem that the working time increases as the suction rate is lowered when the negative pressure ball is sucked by operating the cylinder in the reverse direction.

이에 상술한 바와 같은 종래의 제반 결함을 감안하여 이루어진 것으로, 본 발명의 목적은, 호퍼와 압송관 및 엔드호스 내부에 잔류하는 콘크리트에 급수탱크에 저장된 물을 공급하여 혼합한 후, 레미콘 트럭으로 회수하여 재활용할 수 있는 콘크리트 펌프카의 잔류콘크리트 배출장치 및 방법을 제공함에 있다.
