Abstract

The present invention relates to a mortar supply apparatus for a concrete pump truck using a motor and a screw, which rotates along the screw that helically rotates, so as to convey a concrete rather than moving the concrete in a straight line, thereby allowing for ease of maintenance and supplying the mortar in an easy manner during construction of a super high-rise building. As the mortar supply apparatus of the present invention uses a rotatable motor instead of using a cylinder that provides a straight linear locomotion, the apparatus may be prevented from directly receiving pressure applied in a downward direction, thus may supply the mortar to upper floors in an easier way during construction of a super high-rise building.

이하, 본 발명의 모터와 스크류를 이용한 콘크리트펌프카용 몰탈 공급장치에 대하여 첨부된 도면을 통해 상세히 설명하기로 한다.Hereinafter, a mortar supply device for a concrete pump car using a motor and a screw of the present invention will be described in detail with reference to the accompanying drawings.
본 발명의 모터와 스크류를 이용한 콘크리트펌프카용 몰탈 공급장치는 크게 본체(10), 몰탈공급호퍼(20), 모터(30), 스크류(40), 패킹(50) 및 토출관(60)을 포함하여 구성되어 있다.Mortar supply device for a concrete pump car using a motor and a screw of the present invention includes a main body 10, mortar supply hopper 20, motor 30, screw 40, packing 50 and the discharge pipe 60 It is composed.
본체(10)는 도시된 바와 같이 내부가 빈 관 형상으로 형성되어 있어 일측에 제1개구부(11)가 형성되어 있고, 제1개구부(11)의 반대측에 제2개구부(12)가 형성되어 있다.As shown in the drawing, the main body 10 has a hollow tubular shape, and a first opening 11 is formed at one side thereof, and a second opening 12 is formed at an opposite side of the first opening 11. .
제1개구부(11) 및 제2개구부(12)에는 각각 플랜지가 형성되어 있어 모터(30) 및 토출관(60)과 맞대어 볼트 및 너트에 의해 결합되게 된다.The first opening 11 and the second opening 12 are each formed with a flange so as to be coupled to the motor 30 and the discharge tube 60 by bolts and nuts.
아울러, 본체(10)의 상부 일측에는 호퍼연결구(13)가 형성되어 있다.In addition, the hopper connector 13 is formed on one side of the upper body 10.
몰탈공급호퍼(20)는 상기 본체(10)의 호퍼연결구(13)와 연결되어 있어 외부의 레미콘차 등으로부터 몰탈을 공급받아 상기 본체(10) 내부로 몰탈을 공급하도록 구성되어 있다.The mortar supply hopper 20 is connected to the hopper connector 13 of the main body 10 and is configured to receive mortar from an external ready-mixed concrete vehicle to supply mortar into the main body 10.
모터(30)는 도시된 바와 같이 상기 본체(10)의 제1개구부(11)에 연결되어 설치되어 있고, 일측에 회전축(31)이 설치되어 있는데, 이 회전축(31)은 상기 제2개구부(12) 측을 향해 본체(10) 내부에 삽입되어 있다.As shown in the drawing, the motor 30 is connected to the first opening 11 of the main body 10, and a rotation shaft 31 is provided at one side thereof, and the rotation shaft 31 has the second opening ( 12) It is inserted in the main body 10 toward the side.
이때, 모터(30)의 일측에는 도시된 바와 같이 공지의 감속기(32)를 추가로 설치할 수도 있다.At this time, one side of the motor 30 may be further provided with a known reducer 32 as shown.
스크류(40)는 도시된 바와 같이 일측이 상기 모터(30)의 회전축(31) 둘레를 나선형으로 감싸 설치되어 있다. Screw 40 is one side is installed in a spiral wrap around the rotating shaft 31 of the motor 30.
또, 스크류(40)의 타측은 상기 본체(10) 내벽면과 이격되어 있고, 타측 선단에는 내측은 넓고 외측은 좁은 패킹삽입홈(41)이 형성되어 있어 회전축(31)의 회전에 따라 호퍼연결구(13) 통해 공급된 몰탈을 제2개구부(12) 측으로 이송시키도록 구성되어 있다.In addition, the other side of the screw 40 is spaced apart from the inner wall surface of the main body 10, the other end is formed with a wide inner side and a narrow packing insertion groove 41 on the outer side of the hopper connector according to the rotation of the rotary shaft 31 It is comprised so that the mortar supplied through 13 may be transferred to the 2nd opening part 12 side.
패킹(50)은 스크류(40)의 선단이 본체(10) 내벽면과 맞닿을 경우 마모가 발생하고, 틈이 발생하게 되어 몰탈의 이송이 원할하게 이루어지지 않게 되는 것을 방지하기 위한 것으로 도시된 바와 같이 일측에 상기 패킹삽입홈(41)의 단면 형성에 대응되도록 삽입부(51)가 형성되어 있다.The packing 50 is to prevent wear caused when the tip of the screw 40 abuts the inner wall surface of the main body 10, a gap is generated to prevent the transfer of mortar is not made smoothly. Likewise, the insertion part 51 is formed at one side to correspond to the end face formation of the packing insertion groove 41.
또, 삽입부(51)의 반대편 타측에는 상기 본체(10) 내벽면과 밀착되는 본체밀착부(52)가 형성되어 있다.In addition, on the other side of the insertion portion 51, a main body contact portion 52 in close contact with the inner wall surface of the main body 10 is formed.
이때 본체밀착부(52) 중앙에는 회전축(31)을 향해 내측으로 패여 본체(10) 내벽면과의 사이에 윤활유충진공간을 형성하는 윤활유충진홈(53)이 형성되어 있어 윤활유(100)가 충진되어 있다.At this time, in the center of the main body contact portion 52, a lubricating oil filling groove 53 is formed to be inwardly facing the rotation shaft 31 to form a lubricating oil filling space between the inner wall surface of the main body 10 and the lubricating oil 100 is filled. It is.
이러한 패킹(50)은 특수 고무 등과 같은 플렉시블한 재질로 이루어짐이 바람직하며, 스크류(40) 선단의 패킹삽입홈(41)을 따라 끼워 스크류(40)의 타측 둘레를 감싸 설치됨으로써 용이하게 설치될 수 있다.The packing 50 is preferably made of a flexible material such as a special rubber, and can be easily installed by being wrapped around the other side of the screw 40 by being fitted along the packing insertion groove 41 at the tip of the screw 40. have.
한편, 토출관(60)은 상기 제2개구부(12)에 연결되어 제2개구부(12)를 통해 배출된 몰탈을 외부로 이송시키는 것으로써, 토출관(60)에 플렉시블한 관을 연결하여 몰탈을 시공하기 위한 고층으로 이송시키는 통로 역할을 하게 되어 있다.On the other hand, the discharge pipe 60 is connected to the second opening 12 to transfer the mortar discharged through the second opening 12 to the outside, by connecting a flexible pipe to the discharge pipe 60 mortar It is supposed to act as a passage for transporting to a higher floor for construction.
이러한 구성은 모터(30)의 회전에 따라 회전축(31)이 함께 회전하게 되고, 회전축(31)이 회전함에 따라 회전축(31) 둘레를 감싸 설치되어 있는 스크류(40)가 회전하게 되는 바, 호퍼연결구(13)를 통해 호퍼로 공급된 몰탈이 본체(10) 내부로 유입된 후 스크류(40)의 회전에 따라 나선형으로 회전하면서 토출관(60)측 방향으로 이동하게 된다.In this configuration, the rotary shaft 31 rotates together with the rotation of the motor 30, and the screw 40 installed around the rotary shaft 31 rotates as the rotary shaft 31 rotates. After the mortar supplied to the hopper through the connector 13 is introduced into the main body 10, the mortar is rotated in a spiral according to the rotation of the screw 40 to move toward the discharge tube 60.
이때, 스크류(40)의 선단은 패킹(50)에 의해 본체(10)에 밀착되어 있으므로 압력의 손실이 발생하지 않고 몰탈이 원할히 이송되게 된다.At this time, the tip of the screw 40 is in close contact with the main body 10 by the packing 50 so that the loss of pressure does not occur, the mortar is smoothly transferred.
특히, 패킹(50)의 본체밀착부(52)에 윤활유충진홈(53)이 형성되어 있어 윤활유(100)에 의해 패킹(50)이 본체(10)와 맞닿음에 의한 마찰 저항에 의한 손상을 방지하고 내벽면과 밀착되면서 원할하게 회전할 수 있게 된다.In particular, the lubricating oil filling groove 53 is formed in the main body tight portion 52 of the packing 50, so that the lubricating oil 100 may damage the packing 50 due to frictional resistance caused by the packing 50 contacting the main body 10. Prevent and close to the inner wall surface can be rotated smoothly.
이러한 구성은 종래의 실린더 방식의 경우 직진 운동하는 실린더에 설치된 고가의 램이 몰탈을 타격하면서 발생하는 마찰에 의해 쉽게 손상되는 것에 비해 몰탈을 직접 타격하지 않게 되므로 부품의 손실이 적어지게 되므로 유지 관리가 훨씬 용이해지는 장점을 갖게 된다.In this case, in the case of the conventional cylinder type, the expensive ram installed in the cylinder moving straight does not hit the mortar directly, as it is easily damaged by the friction generated while hitting the mortar. It has the advantage of being much easier.
또한, 고층에 몰탈을 공급하기 위해서는 실린더의 압력이 높아야 했으며, 이에 따라 일정한 높이 이상의 건물에는 몰탈 공급에 제한이 있었으나, 상기와 같이 모터(30)의 회전에 의해 몰탈을 이송시키게 되므로 높은 건물에 몰탈의 공급이 용이하므로 성능이 더 우수하고, 고성능의 실린더 대신 모터(30)를 사용함에 의해 제품의 단가가 더 저렴해지게 된다.In addition, in order to supply mortar to the high floor, the pressure of the cylinder had to be high. Accordingly, there was a limit to the supply of mortar to a building of a certain height or higher, but as the mortar is transferred by the rotation of the motor 30 as described above, mortar to the high building Since the supply is easy, the performance is better, and by using the motor 30 instead of the high-performance cylinder, the unit price of the product becomes cheaper.
상기와 같은 구성에 있어서 도시된 바와 같이, 상기 회전축(31)의 일측에는 윤활유유입구(70)가 형성되어 있고, 상기 스크류(40)의 윤활유충진홈(53)에는 윤활유배출구(71)가 형성되어 있고, 상기 윤활유유입구(70)로부터 윤활유배출구(71)를 연결하는 윤활유이송통로(72)가 형성되어 있어 윤활유유입구(70)를 통해 윤활유충진공간으로 윤활유(100)를 공급하도록 구성할 수 있다.As shown in the above configuration, one side of the rotary shaft 31 is formed with a lubricating oil inlet 70, the lubricating oil filling groove 53 of the screw 40 is formed with a lubricating oil outlet 71 The lubricating oil inlet 70 is formed from a lubricating oil inlet 70 connecting the lubricating oil outlet 71 to the lubricating oil filling space through the lubricating oil inlet 70.
이러한 구성은 윤활유충진공간에 지속적으로 공급할 수 있어 패킹(50)의 마모율을 보다 줄일 수 있게 되어 유지보수 시간을 절감할 수 있게 된다.This configuration can be continuously supplied to the lubricating oil filling space can further reduce the wear rate of the packing 50 can be reduced maintenance time.
상기와 같이 작동되도록 하기 위하여, 윤활유유입구(70)측 둘레에는 윤활유공급관(73)과 연결된 연결부재(74)를 회전축(31)을 감싸 설치하고, 그 내측에 제1볼베어링(75)을 설치하여 회전축(31)의 회전과 관계없이 연결부재(74)는 회전하지 않으면서 윤활유유입구(70)로 윤활유(100)를 공급할 수 있도록 함이 바람직하다.In order to operate as described above, the connecting member 74 connected to the lubricating oil supply pipe 73 is installed around the rotating shaft 31 around the lubricating oil inlet 70, and the first ball bearing 75 is installed inside the lubricating oil inlet 70. Regardless of the rotation of the rotary shaft 31, the connecting member 74 is preferably capable of supplying the lubricating oil 100 to the lubricating oil inlet 70 without rotating.
한편, 본체(10) 내부의 몰탈이 경화되어 본체(10) 내벽면에 달라붙을 경우 스크류(40)의 회전을 방해하는 것은 물론, 패킹(50)과 달라붙은 몰탈이 마찰을 일으켜 패킹(50)이 손상될 수 있다.On the other hand, when the mortar inside the main body 10 is hardened and stuck to the inner wall surface of the main body 10, as well as the rotation of the screw 40, as well as the mortar stuck to the packing 50 causes friction and packing 50 This can be damaged.
이를 위해 본체(10) 내부를 자주 청소해줌이 바람직한데, 이를 위해 본체(10) 내부에 제2개구부(12)를 통해 배출 가능하도록 구성된 보조케이스(80)가 삽입되도록 구성할 수 있다.To this end, it is preferable to frequently clean the inside of the main body 10. For this purpose, the auxiliary case 80 configured to be discharged through the second opening 12 may be inserted into the main body 10.
즉, 보조케이스(80)의 선단에 플랜지를 형성하여 토출관(60)과 플랜지를 서로 맞대 볼트 결합하여 연결상태를 유지하다 보조케이스(80)를 본체(10) 내부에서 꺼낼 때는 볼트 및 너트를 풀어 토출관(60)을 분리한 후 보조케이스(80)를 제2개구부(12) 측으로 잡아당겨 꺼내 청소하고, 다시 삽입할 수 있다.That is, a flange is formed at the front end of the auxiliary case 80 so that the discharge pipe 60 and the flange are butt-coupled to each other to maintain the connection state. When removing the auxiliary case 80 from the inside of the main body 10, bolts and nuts are removed. After removing and discharging the discharge tube 60, the auxiliary case 80 may be pulled out to the second opening 12 and cleaned and inserted again.
이때, 본체(10) 내부에 설치된 보조케이스(80)를 본체(10)에 고정된 방식이 아닌 회전 가능한 방식으로 구성할 수도 있다.At this time, the auxiliary case 80 installed inside the main body 10 may be configured in a rotatable manner rather than a fixed manner to the main body 10.
이 경우 스크류(40)의 회전에 의해 패킹(50)과 보조케이스(80) 내벽면과의 사이에 발생하는 마찰을 경감시켜 패킹(50)의 손상을 방지할 수 있다.In this case, damage to the packing 50 may be prevented by reducing friction generated between the packing 50 and the inner wall surface of the auxiliary case 80 due to the rotation of the screw 40.
이를 위해 본체(10) 내벽면과 보조케이스(80) 사이에는 제2볼베어링(81)을 설치하고, 토출관(60)과 보조케이스(80)는 도 3과 달리 서로 연결관계를 갖지 않고 미도시되었지만 본체(10)와 토출관(60)이 서로 맞대어 볼트 결합할 수 있다.To this end, a second ball bearing 81 is installed between the inner wall surface of the main body 10 and the auxiliary case 80, and the discharge pipe 60 and the auxiliary case 80 do not have a connection relationship with each other unlike FIG. 3. However, the main body 10 and the discharge pipe 60 may be bolted to each other.
즉, 회전축(31)과 스크류(40)가 회전할 때 스크류(40) 선단의 패킹(50)과 보조케이스(80)가 맞닿은 상태에서 마찰이 발생할 때 보조케이스(80)가 유동성을 가짐으로써 패킹(50)의 손상을 최대한 경감시킬 수 있게 되는 것이다.That is, when the rotation shaft 31 and the screw 40 rotates, the auxiliary case 80 has fluidity when the friction occurs in the state where the packing 50 and the auxiliary case 80 of the tip of the screw 40 come into contact with each other. The damage of (50) can be reduced as much as possible.
한편, 상기와 같은 구성에 있어서 모터(30)는 양방향으로 회전 가능한 모터(30)로 구성됨이 바람직하다.On the other hand, in the configuration as described above, the motor 30 is preferably composed of a motor 30 that can rotate in both directions.
이는 토출관(60)을 통해 몰탈의 공급이 끝난 상태에서 토출관(60) 및 본체(10) 내부에 채워져 있는 몰탈을 회수할 때 종래와 같은 별도의 회수장치 없이 단순히 모터(30)를 역방향으로 회전시켜 몰탈을 다시 회수할 수 있게 된다.This is to recover the mortar filled in the discharge tube 60 and the main body 10 in the state where the mortar is supplied through the discharge tube 60, simply reverse the motor 30 in the reverse direction without a separate recovery device as in the prior art It can be rotated to recover mortar again.
이때, 상기 본체(10) 일측에 몰탈회수구(90)가 형성되어 있어 모터(30)의 회전 방향에 따라 토출관(60) 내부의 몰탈을 본체(10)로 이송시켜 몰탈회수구(90)를 통해 배출할 수 있도록 할 수도 있다.At this time, the mortar recovery hole 90 is formed on one side of the main body 10 to transfer the mortar inside the discharge pipe 60 to the main body 10 according to the rotation direction of the motor 30 to the mortar recovery hole 90. Can also be discharged through
즉, 통상적으로 몰탈공급호퍼(20)가 본체(10) 상부에 설치되는 바, 몰탈회수구(90)를 본체(10) 하부에 설치함으로써 본체(10) 내부의 제1개구부(11) 측으로 이송된 몰탈이 몰탈회수구(90)를 통해 외부로 낙하하여 배출되도록 하는 것이다.That is, typically, the mortar supply hopper 20 is installed on the main body 10, and the mortar recovery hole 90 is installed below the main body 10 to be transferred to the first opening 11 in the main body 10. The mortar is to fall to the outside through the mortar recovery hole (90) to be discharged.
이러한 구성에 있어서상기 호퍼연결구(13) 및 몰탈회수구(90)에는 각각 제1밸브(13a) 및 제2밸브(91)를 설치하여 선택적으로 개폐시키도록 구성됨이 바람직하다.In such a configuration, the hopper connector 13 and the mortar recovery port 90 are preferably configured to selectively open and close the first valve 13a and the second valve 91, respectively.
이상과 같이 구성된 본 발명의 모터와 스크류(40)를 이용한 콘크리트펌프카용 몰탈 공급장치는 비단 콘크리트 몰탈의 이송에만 적용되는 것은 아니며 높은 압력을 받으면서 점성이 높은 물질을 이송시키는 다양한 분야에 적용될 수 있다 할 것이다.Mortar supply device for a concrete pump car using the motor and screw 40 of the present invention configured as described above is not only applied to the transfer of concrete mortar, but may be applied to various fields for transferring high viscosity materials under high pressure. will be.
