Description

콘크리트 믹서트럭 및 레미콘 제조방법{A TRUCK AND METHOD FOR PRODUCING READY MIXED CONCRETE}Concrete mixer truck and ready-mixed concrete manufacturing method {A TRUCK AND METHOD FOR PRODUCING READY MIXED CONCRETE}

본 발명은 콘크리트 믹서트럭 및 레미콘 제조방법에 관한 것으로, 특히 운행시 믹서드럼을 하강시켜 그 무게중심을 낮추고, 레미콘생산공장에서 건식레미콘을담아 건설현장에서 습식레미콘을 생산함으로써 레미콘의 응고를 획기적으로 방지하는 콘크리트 믹서트럭 및 레미콘 제조방법에 관한 것이다.The present invention relates to a method for manufacturing a concrete mixer truck and ready-mixed concrete, and in particular, by lowering the mixer drum during operation, lowering its center of gravity and putting dry ready-mixed concrete at the ready-mixed concrete production plant to produce wet ready-mixed concrete at the construction site. It relates to a concrete mixer truck and ready-mixed concrete manufacturing method to prevent.

일반적으로, 콘크리트 믹서트럭은 레미콘의 생산공장에서 시멘트, 모래, 자갈 및 물을 배합비율에 맞춰 배합한 레미콘을 1회에 약 1.1∼4.5㎥의 양을 실어 공사현장으로 운반하게 된다.In general, a concrete mixer truck carries a ready-mixed concrete mixed with cement, sand, gravel and water in a production plant of ready-mixed concrete at a ratio of about 1.1 to 4.5m 3 at a time to the construction site.

이때, 콘크리트 믹서트럭은 레미콘의 운반과정에서 도1에 도시한 바와같이 믹서드럼(2)에 담긴 레미콘의 응고를 방지하기 위하여 유압모터(3) 및 감속기(9)를 작동시켜 믹서드럼(2)을 약 6∼8rpm의 속도로 회전시키면서 믹서드럼의 레미콘을 교반시키게 된다.At this time, the concrete mixer truck operates the hydraulic motor (3) and the reducer (9) in order to prevent solidification of the ready-mixed concrete in the mixer drum (2) as shown in FIG. While stirring at about 6 ~ 8rpm the mixer drum of the mixer drum is stirred.

또한, 콘크리트 믹서트럭은 도2에 도시한 바와같이 믹서드럼(2)에 담긴 레미콘의 누출을 방지하기 위하여 투입호퍼(5) 및 배출슈트(6)측이 위로 향하도록 믹서드럼(2)이 약 16。의 경사를 이루고 있다.In addition, as shown in FIG. 2, the mixer mixer 2 is weakly placed so that the input hopper 5 and the discharge chute 6 face upwards to prevent leakage of ready-mixed concrete contained in the mixer drum 2, as shown in FIG. It is inclined at 16 degrees.

따라서, 콘크리트 믹서트럭은 그 무게중심이 일반차량에 비해 약 20%이상 높게 형성되어 커브길에서 급하게 선회하거나 연약한 지반 및 경사진 노면을 주행할 때 전복할 위험이 매우 높다.Therefore, the concrete mixer truck has a high center of gravity that is about 20% higher than that of a general vehicle, and thus, the concrete mixer truck has a high risk of overturning when turning sharply on a curve or driving on soft ground and sloped roads.

더욱이, 레미콘생산공장에서 생산되는 레미콘은 온도 25℃에서 90분이상 경과되면 응고되어 사용이 불가능하게 된다.Moreover, the ready-mixed concrete produced in the ready-mixed concrete production plant becomes solidified after 90 minutes at a temperature of 25 ° C., and thus cannot be used.

그러나, 현실적으로 레미콘생산공장에서 건설현장까지 소요되는 시간은 레미콘의 유효시간을 초과하는 경우가 많고, 이럴 경우 건설현장에서는 레미콘에 물타기를 하여 사용함으로써 부실시공을 유발하기도 한다.However, in reality, the time required from the ready-mixed concrete production plant to the construction site often exceeds the effective time of the ready-mixed concrete. In this case, the construction site may also cause construction work by using water for the ready-mixed concrete.

본 발명은 운행시 믹서드럼을 하강시켜 그 무게중심을 낮춤으로써 전복의 위험을 현저히 감소시키고, 레미콘생산공장에서 건식레미콘을 담아 건설현장에서 습식레미콘을 생산함으로써 레미콘의 응고를 획기적으로 방지할 수 있는 콘크리트 믹서트럭 및 레미콘 제조방법을 제공함에 그 목적이 있다.The present invention can significantly reduce the risk of overturning by lowering the center of gravity by lowering the mixer drum during operation, and can produce a wet ready-mixed concrete at the construction site containing dry ready-mixed concrete at the ready-mixed concrete production plant to prevent breakage of ready-mixed concrete. The purpose is to provide a concrete mixer truck and ready-mixed concrete manufacturing method.

도면을 참조하여 본 발명의 구성을 설명한다.The configuration of the present invention will be described with reference to the drawings.

도3a,b는 본 발명에 따른 콘크리트 믹서트럭을 나타내는 정면도이고, 도4a,b는 본 발명에 따른 콘크리트 믹서트럭의 작동상태를 나타내는 상태도이며, 도5는 본 발명에 따른 콘크리트 믹서트럭을 나타내는 요부정면도이다.Figure 3a, b is a front view showing a concrete mixer truck according to the invention, Figures 4a, b is a state diagram showing the operating state of the concrete mixer truck according to the invention, Figure 5 is a main part showing a concrete mixer truck according to the present invention Front view.

본 발명에 따른 저중심형 콘크리트 믹서트럭은 차체프레임(1)에 베이스(7)가 고정 설치되어 있고, 이 베이스(7)의 상부에 유압모터(3-1)에 의해 구동되는 감속기(9-1)가 링크핀(10)을 중심으로 회전하도록 결합되어 있다.The low center of gravity concrete mixer truck according to the present invention has a base (7) fixed to the body frame (1), the reduction gear (9-1) driven by a hydraulic motor (3-1) on the upper portion of the base (7) ) Is coupled to rotate about the link pin (10).

이때, 감속기(9-1)의 동력축에는 믹서드럼(2-1)의 중심축이 체결되어 있고, 유압모터(3-1)를 구동할 경우 감속기(9-1)가 감속 회전하면서 믹서드럼(2-1)을 회전시키게 된다.At this time, the central shaft of the mixer drum 2-1 is fastened to the power shaft of the reducer 9-1, and when the hydraulic motor 3-1 is driven, the reducer 9-1 decelerates and rotates the mixer drum. Will rotate (2-1).

그리고, 믹서드럼(2-1)의 후방측 하부에 위치하도록 차체프레임(1)에 고정 부착되는 고정프레임(23)에는 그 내측에 형성되는 레일을 따라 상하강프레임(21)이 실린더(22)에 의해 상하이동되도록 결합되어 있다.In addition, the fixed frame 23 fixedly attached to the vehicle body frame 1 so as to be positioned at the lower rear side of the mixer drum 2-1 has a cylinder 22 having a vertically lowered frame 21 along a rail formed therein. It is combined to be shanghai.

여기서, 상하강프레임(21)의 상면에는 2개의 가이드롤러(4-1)가 설치되어 있고, 이 가이드롤러는 상하강프레임의 상승시 믹서드럼의 하부에 밀착되어 회전하는믹서드럼을 지지하게 된다.Here, two guide rollers 4-1 are provided on an upper surface of the up and down frame 21, and the guide rollers are in close contact with the lower part of the mixer drum when the up and down frame is raised to support the rotating mixer drum. .

또한, 믹서드럼(2-1)에 감기면서 그 양단이 상하강프레임(21)의 양측 상단에 고정 부착되는 고정밴드(8-1)는 상하강프레임이 상승되면 느슨해지면서 믹서드럼의 외주면으로 이격되지만 상하강프레임이 하강되면 밑으로 당겨지면서 믹서드럼의 외주면에 밀착되어 운행중 믹서드럼의 흔들림을 방지하게 된다.In addition, the fixing band 8-1, which is wound around the mixer drum 2-1 and fixedly attached to both upper ends of the upper and lower frames 21, becomes loose when the upper and lower frames are raised, and is spaced apart from the outer peripheral surface of the mixer drum. However, when the up and down frame is lowered, it is pulled down and is in close contact with the outer peripheral surface of the mixer drum to prevent shaking of the mixer drum during operation.

한편, 그 하단이 상하강프레임(21)에 고정 부착되는 고정프레임(29)에는 그 상부에 호퍼(5-1)가 고정대(28)에 의해 고정 설치되어 있고, 호퍼(5-1)의 하부측에 위치하는 반원판의 드럼커버(27)가 실린더(26)에 의해 전후진되도록 설치되어 있다.On the other hand, in the fixed frame 29, the lower end of which is fixedly attached to the up and down frame 21, the hopper 5-1 is fixed to the upper part by the fixing stand 28, and the lower part of the hopper 5-1. The drum cover 27 of the semicircle plate located at the side is provided so as to be advanced back and forth by the cylinder 26.

이때, 호퍼(5-1)에는 그 하부측 외주면에 바이브레이터(Vibrator)(25)가 고정 부착되어 있고, 이 바이브레이터는 호퍼(5-1)를 통해 믹서드럼(2-1)에 건식레미콘 투입시 호퍼에 진동을 주어 건식레미콘의 유동성을 향상시키게 된다.At this time, a vibrator 25 is fixedly attached to the lower circumferential surface of the hopper 5-1, and the vibrator is supplied with dry concrete into the mixer drum 2-1 through the hopper 5-1. Vibration to the hopper improves the flowability of dry concrete.

그리고, 드럼커버(27)는 실린더(26)의 전진작동에 의해 믹서드럼(2-1)의 입구에 밀착되어 믹서드럼의 하향 회전시 믹서드럼내의 레미콘이 누출되는 현상을 방지하게 된다.Then, the drum cover 27 is in close contact with the inlet of the mixer drum (2-1) by the forward operation of the cylinder 26 to prevent the phenomenon of ready-mixed concrete in the mixer drum leaks when the mixer drum is rotated downward.

또한, 반원통형의 슈트(30)는 드럼커버(27)의 하부측에 위치하도록 지지대(32)에 의해 상하강프레임(21)에 고정 설치되어 있고, 슈트와 드럼커버 사이에 위치하도록 고정프레임(29)에 고정되는 스쿠프(31)는 믹서드럼(2-1)의 입구로부터 배출되는 레미콘을 슈트(30)로 안내하는 역활을 하게 된다.In addition, the semi-cylindrical chute 30 is fixed to the up and down frame 21 by the support 32 so as to be located on the lower side of the drum cover 27, and fixed frame (to be located between the chute and the drum cover) The scoop 31 fixed to 29 serves to guide the ready-mixed concrete discharged from the inlet of the mixer drum 2-1 to the chute 30.

한편, 차체프레임(1)의 전방측에 설치되어 있는 물탱크(15)와 펌프(16)는 건설현장에서 믹서드럼(2-1)에 물을 공급하여 건식레미콘을 습식레미콘으로 혼합하게 된다.Meanwhile, the water tank 15 and the pump 16 installed at the front side of the body frame 1 supply water to the mixer drum 2-1 at the construction site to mix the dry ready mixed concrete into the wet ready mixed concrete.

이때, 건설현장에 물공급이 가능할 경우 레미콘생산공장에서 물탱크(15)에 별도 물을 저장하여 운반할 필요가 없기 때문에 운행중 콘크리트 믹서트럭의 적재중량을 감소시킬 수 있게 된다.At this time, when water can be supplied to the construction site, it is not necessary to store and transport water in the water tank 15 separately in the ready-mixed concrete production plant, thereby reducing the loading weight of the concrete mixer truck during operation.

이하, 본 발명의 작용을 설명한다.The operation of the present invention will be described below.

먼저, 콘크리트 믹서트럭은 실린더(22)가 상승 작동되면서 상하강프레임(21)이 상승되고, 이에 따라 가이드롤러(4-1)가 상승되면서 믹서드럼(2-1)을 상승시켜 약 16。의 경사를 이루도록 하는 동시에 고정밴드(8-1)가 믹서드럼의 외주면으로부터 이격되어 믹서드럼의 회전을 방해하지 않도록 한다.First, the concrete mixer truck ascending the cylinder 22, the up and down frame 21 is raised, thereby raising the guide roller (4-1) to raise the mixer drum (2-1) of about 16 ° At the same time, the fixing band 8-1 is spaced apart from the outer circumferential surface of the mixer drum so as not to interfere with the rotation of the mixer drum.

아울러, 상하강프레임(21)의 상승에 따라 고정프레임(29)이 상승되면서 호퍼(5-1)의 출구가 믹서드럼(2-1)의 입구에 일치되고, 실린더(26)가 후진 작동되면서 드럼커버(27)가 믹서드럼의 입구로부터 이격된다.In addition, as the fixed frame 29 rises as the up and down frame 21 rises, the outlet of the hopper 5-1 coincides with the inlet of the mixer drum 2-1, and the cylinder 26 operates backward. The drum cover 27 is spaced apart from the inlet of the mixer drum.

이때, 모터(3-1)를 작동시켜 감속기(9-1)를 구동시키게 되면 믹서드럼(2-1)이 가이드롤러(4-1)에 의해 지지된 상태로 혼합방향으로 회전하게 되고, 이러한 회전상태의 믹서드럼(2-1)에 건식레미콘(시멘트,모래,자갈을 배합한 상태)을 호퍼(5-1)를 통해 투입하게 된다.At this time, when driving the reducer 9-1 by operating the motor 3-1, the mixer drum 2-1 rotates in the mixing direction while being supported by the guide roller 4-1. Dry mixed concrete (mixed with cement, sand, and gravel) is introduced into the mixer drum 2-1 in a rotating state through the hopper 5-1.

여기서, 호퍼(5-1)를 통한 건식레미콘의 투입을 용이하게 하기 위하여 바이브레이터(25)를 작동시켜 호퍼에 진동을 주게 된다.Here, the vibrator 25 is operated to vibrate the hopper in order to facilitate the introduction of the dry ready-mixed concrete through the hopper 5-1.

그리고, 레미콘생산공장에서 믹서드럼(2-1)내의 건식레미콘투입이 완료되면모터(3-1)와 바이브레이터(25)의 작동을 정지시키고, 실린더(22)를 하강 작동시키면 상하강프레임(21)이 하강되면서 가이드롤러(4-1)와 고정프레임(29)이 밑으로 처지게 된다.When the dry concrete mixing unit in the mixer drum 2-1 is completed in the ready-mixed concrete production plant, the operation of the motor 3-1 and the vibrator 25 is stopped, and the lowering operation of the cylinder 22 causes the cylinder 22 to move up and down. ) And the guide roller (4-1) and the fixed frame (29) is drooped downward.

이때, 가이드롤러(4-1)에 의해 지지되는 믹서드럼(2-1)이 링크핀(10)을 중심으로 회전되면서 차체프레임(1)에 안착되고, 상하강프레임(21)에 의해 밑으로 당겨지는 고정밴드(8-1)는 믹서드럼의 외주면에 밀착되면서 운행중 믹서드럼을 고정시키게 된다.At this time, the mixer drum 2-1 supported by the guide roller 4-1 is seated on the body frame 1 while being rotated about the link pin 10, and is moved downward by the up and down frame 21. The fixed band 8-1 to be pulled is fixed to the mixer drum while driving while being in close contact with the outer circumferential surface of the mixer drum.

또한, 고정프레임(29)이 하강되면서 호퍼(5-1)가 믹서드럼(2-1)과 함께 하강되면 실린더(26)를 전진작동시켜 드럼커버(27)를 믹서드럼(2-1)의 입구에 밀착시키게 된다.In addition, when the fixed frame 29 is lowered and the hopper 5-1 is lowered together with the mixer drum 2-1, the cylinder 26 is moved forward to operate the drum cover 27 of the mixer drum 2-1. Closed to the entrance.

여기서, 믹서드럼(2-1)이 약 16。의 경사에서 약 6。의 경사로 하향 회전되면서 믹서드럼의 내부에 담고 있는 건식레미콘이 믹서드럼의 입구측으로 쏠리게 되지만 반원판의 드럼커버(27)가 믹서드럼의 입구를 막음으로써 누출의 문제는 발생되지 않게 된다.Here, while the mixer drum 2-1 is rotated downward from the inclination of about 16 ° to the inclination of about 6 °, the dry ready-mixed concrete contained in the inside of the mixer drum is directed to the inlet side of the mixer drum, but the drum cover 27 of the semicircle is Blocking the inlet of the mixer drum eliminates the problem of leakage.

그리고, 레미콘생산공장에서 건식레미콘을 담은 콘크리트 믹서트럭은 믹서드럼(2-1)에 물을 섞지 않은 건식레미콘을 적재함으로써 적재중량중 약 7.51%인 1,026㎏을 감소시키는 효과를 낼 수 있게 된다.In addition, the concrete mixer truck containing dry ready-mixed concrete at the ready-mixed concrete production plant is capable of reducing 1,026 kg of about 7.51% of the loading weight by loading dry mixed concrete without mixing water in the mixer drum (2-1).

또한, 믹서드럼(2-1)이 하향 선회되어 그 무게중심이 낮추어짐으로써 콘크리트 믹서트럭의 운행중 전복사고의 위험이 현저히 감소된다.In addition, since the mixer drum 2-1 is pivoted downward and the center of gravity thereof is lowered, the risk of a rollover accident during operation of the concrete mixer truck is significantly reduced.

무엇보다도, 본 발명에 따른 콘크리트 믹서트럭은 건식레미콘을 운반하기때문에 레미콘생산공장에서 건설현장까지 운행중 레미콘이 응고되는 문제는 원천적으로 발생되지 않는다.Above all, since the concrete mixer truck according to the present invention carries dry concrete, the problem that the concrete is solidified during operation from the ready-mixed concrete production plant to the construction site does not occur.

한편, 콘크리트 믹서트럭이 건설현장에 도착하면 실린더(22)를 상승 작동시켜 상하강프레임(21)을 상승시키게 되고, 이에 따라 가이드롤러(4-1)가 상승되면서 믹서드럼(2-1)을 상승시켜 약 16。의 경사를 이루도록 하는 동시에 고정밴드(8-1)가 믹서드럼의 외주면으로부터 이격되어 믹서드럼의 회전을 방해하지 않도록 한다.Meanwhile, when the concrete mixer truck arrives at the construction site, the cylinder 22 is moved upward to raise and lower the up and down frame 21. As a result, the guide roller 4-1 is raised to raise the mixer drum 2-1.
