Description

콘크리트 수관 성형라인의 몰드지지장치Mold supporting device of concrete water pipe forming line

본 발명은 콘크리트 수관의 성형작업시 진동테이블로부터 발생되는 진동을 몰드에 전달해 주도록 함에 있어 서로간의 마찰음은 최소화하면서도 진동효과는 극대화시켜 줄 수 있는 몰드 지지장치에 관한 것이다.The present invention relates to a mold support device capable of maximizing the vibration effect while minimizing the friction noise between each other in transmitting the vibration generated from the vibration table during the molding of the concrete water pipe.

일반적으로 널리 이용되고 콘크리트 수관 성형라인은 몰탈공급대차가 활주하는 종레일과, 몰드가 활주하는 횡레일의 교차지점에 진동테이블을 설치하여 몰탈공급대차로부터 몰드내에 몰탈이 공급되면 진동테이블의 상승 및 진동작동으로 몰드내에 공급된 몰탈로부터 기포가 제거되고 또 고른 표면을 유지해 줄수 있도록 하게되며 또한 근래에는 진동효과의 극대화를 위하여 진동장치로서 고주파진동발생기와 저주파진동발생기가 널리 이용되고 있다.In general, the concrete water pipe forming line has a vibrating table installed at the intersection of the longitudinal rail on which the mortar feed truck slides and the transverse rail on which the mold slides. In order to remove bubbles from the mortar supplied in the mold and maintain an even surface by vibrating operation, high frequency vibration generators and low frequency vibration generators have been widely used as vibration devices in order to maximize the vibration effect.

그러나 이때 진동테이블은 단순히 에어스프링에 의한 상승으로 몰드와 접하여 있게 되면 진동테이블의 진동시 몰드와 심한 마찰음을 발생시키게 되며 그 진동력 또한 제대로 전달되지 않게 된다.However, when the vibration table is in contact with the mold simply by the lift by the air spring, the vibration table generates severe friction sound when the vibration table vibrates, and the vibration force is also not properly transmitted.

따라서 종래에도 도4에서와 같이 몰드(50)의 양측으로부터는 지지편(52)(54)을 돌출형성하고 상기 지지편(52)(54)의 상부에는 각각 지면에 고정된 받침편(56)(58)의 탄성체(60)(62)가 약간의 간격을 두고 위치케하여 진동테이블(64)이 상승작동함에 따라 몰드(50)의 지지편(52)(54)이 탄성체(60)(62)와 강한 힘으로 접하게 하여 진동테이블(64)과 몰드(50)의 마찰음을 줄이고 진동이 최대한 전달되도록 하고 있다.Therefore, in the related art, as shown in FIG. 4, the supporting pieces 52 and 54 are protruded from both sides of the mold 50, and the supporting pieces 56 fixed to the ground on the upper portions of the supporting pieces 52 and 54, respectively. As the elastic bodies 60 and 62 of the 58 are positioned at a slight interval, and the vibration table 64 is moved up, the support pieces 52 and 54 of the mold 50 are elastic bodies 60 and 62. ) And a strong force to reduce the friction noise of the vibrating table 64 and the mold 50 so that the vibration is transmitted as possible.

그러나 이러한 구성의 몰드 지지장치는 진동이 가해지는 진동테이블(64)이 아닌 지면에 고정된 받침편(56)(58)이 몰드(50)를 지지토록 하므로서 서로간의 밀착력은 진동테이블(64)의 상승력에 의해 좌우될 수 밖에 없어 진폭이나 진동력이 크면 클수록 마찰음이 크게 발생된다.However, the mold supporting device of this configuration is such that the support pieces 56 and 58 fixed to the ground support the mold 50, not the vibration table 64 to which vibration is applied, so that the adhesion between each other is reduced. Inevitably depends on the lifting force, the greater the amplitude or vibration force, the greater the friction sound.

특히 진동테이블(64)로부터 발생된 진동은 몰드(50)에 전달되면서 몰드(50)를 지지하는 받침편(56)(58)이 일부 제진 흡수하게 되므로 고주파 진동발생기 및 저주파 진동발생기의 사용에도 불구하고 진동효과를 극대화 시켜줄수 없어 양질의 제품을 얻기 어려운 등의 많은 문제점들이 따르게 되는 것이었다.In particular, the vibration generated from the vibrating table 64 is transmitted to the mold 50, so that the support pieces 56 and 58 supporting the mold 50 are damped and absorbed, so that despite the use of the high frequency vibration generator and the low frequency vibration generator, Many problems, such as difficult to obtain a good quality product can not follow the vibration effect.

이에 본 발명은 상술한 종래에 문제점들을 해결하기 위하여 진동테이블로부터 몰드를 가압지지토록 하되 서로간에 강한 힘으로 일체감있게 밀착연결되게 하므로서 진동시 마찰음을 최소화하고 또 서로간의 일체감으로 같은 진폭으로 진동할 수 있게 되므로 진동효과의 극대화로 보다 양질의 제품을 얻을 수 있도록 함을 목적으로 한 것이다.In order to solve the above problems, the present invention allows the mold to be pressurized from the vibrating table so as to be tightly connected to each other with a strong force, thereby minimizing friction during vibration and vibrating at the same amplitude with a sense of unity with each other. It is intended to obtain a higher quality product by maximizing the vibration effect.

상기한 목적달성을 위하여 본 발명은 진동테이블 상면에 에어스프링을 사이에 두고 좌우 가압편을 축핀으로 연결설치하고 상기 좌우 가압편은 에어스프링과 링크로 연결하여 에어스프링의 작동으로 각각 외측으로 확개되게 하고 몰드의 저면 양측에는 각각 가압편과 외측으로부터 마주하는 지지편을 돌출형성하여 좌우 가압편의 확개시 각기 몰드의 지지편과 강한 힘으로 접하여 진동테이블과 몰드가 서로 일체감있게 연결되도록 한 것이다.In order to achieve the above object, the present invention is installed by connecting the left and right pressure pieces with the shaft pins on the upper surface of the vibration table, and the left and right pressure pieces are connected to the air spring and the link to be extended to the outside by the operation of the air spring, respectively. And both sides of the bottom of the mold is formed by protruding the support piece facing each other from the pressing piece and the outside, so that the vibrating table and the mold are connected with each other by contacting with the support piece of the mold with a strong force when expanding the left and right pressing pieces.

상기에 있어 가압편을 통한 지지편의 가압시에는 가급적 가압편이 지지편을 하방으로 가압지지토록 해 주어야 하며 이러한 경우 가압편은 진동테이블의 상승력과 반대방향으로 가압력이 작동하게 되므로 서로간의 강한 밀착력을 기대할 수 있게 된다.In the above, when pressurizing the support piece through the pressing piece, the pressing piece should be pressed downward to support the support piece as much as possible. In this case, the pressing piece is expected to have strong adhesion between each other because the pressing force operates in the opposite direction to the lifting force of the vibration table. It becomes possible.
