본 발명은 산업용 차량의 붐 속도에 관한 것으로, 특히 콘크리트 펌프트럭의 붐 속도를 제어하는 장치에 관한 것이다.The present invention relates to the boom speed of an industrial vehicle, and more particularly to an apparatus for controlling the boom speed of a concrete pump truck.
일반적으로 콘크리트 펌프트럭은 건설현장에서 콘크리트를 타설을 위하여 고층 작업현장으로 콘크리트를 이송해 주는 산업차량으로서, 대용량의 호퍼에 쌓여진 콘크리트를 유압 실린더의 힘에 의해, 붐에 의해 지지된 콘크리트 이송관을 통해 작업현장으로 이송하도록 되어 있다.In general, a concrete pump truck is an industrial vehicle that transfers concrete to a high-rise work site for placing concrete at a construction site. The concrete pump pipe is a concrete transport pipe supported by a boom by a hydraulic cylinder. It is intended to be transferred to the shop floor.
이때 콘크리트 이송관을 지지하는 붐은, 콘크리트를 필요로 하는 작업현장에 콘크리트가 정확히 이송될 수 있도록 이송관의 방향 및위치를 조정하는데, 통상 고층까지 전달할 수 있도록 완전히 펼쳤을 때의 길이가 36M 내지는 62M에 이른다.At this time, the boom supporting the concrete conveying pipe adjusts the direction and position of the conveying pipe so that the concrete can be accurately conveyed to the work site requiring the concrete. The length of the boom when fully unfolded to deliver to the high floor is usually 36M to 62M. Leads to
따라서 붐은 이동시에 주위시설에 부딪치지 않도록 다단으로 접을 수 있도록 되어 있으며(최대 길이에 따라 통상 4단 혹은 5단으로 되어 있다). 붐의 방향은 콘크리트 펌프트럭 상부선회체(붐 선회장치)의 회전에 의해 360도 방향으로 조정될 수 있고, 각 단의 펼쳐지는 각도에 따라 원하는 위치로 이송관의 앤드호스를 이동시켜 콘크리트를 타설할 수 있도록 되어 있다.Therefore, the boom can be folded in multiple stages so as not to hit the surrounding facilities during movement (usually four or five stages depending on the maximum length). The direction of the boom can be adjusted in the 360 degree direction by the rotation of the upper body of the concrete pump truck (boom turning device), and the concrete can be placed by moving the end hose of the transfer pipe to the desired position according to the unfolding angle of each stage. It is supposed to be.
그리고 붐의 회전방향은 조작장치(control box)에서 조작할 수 있으며, 붐을 펼치는 조작 및 펌프 작동시의 미세한 움직임 조작을 원격조정장치에 의해 작업현장근접거리에서 현장을 확인하면서 조정할 수 있도록 되어 있다.And the direction of rotation of the boom can be controlled from a control box, and the boom unfolding and fine movements during pump operation can be adjusted while checking the site at the work site proximity by the remote control device. .
그런데 종래의 콘크리트 펌프트럭에 있어서, 붐을 펼치는(즉, 상하로 움직이는) 속도는 고정되어 있었기(즉, 속도조절이 되지 않았기) 때문에, 붐의 운동시 처음 출발이 급작스럽게 이루어져 인사사고가 발생되거나 구조물과 충둘하게 되는 경우가 많았다.However, in the conventional concrete pump truck, since the speed at which the boom is unfolded (that is, moved up and down) is fixed (that is, the speed is not adjusted), the start of the boom is suddenly started and a personnel accident occurs. In many cases, the structure was filled with.
즉, 종래의 붐 조작은 제2도에 도시된 바와 같이, 조이스틱(1)을 조작하여 릴레이(21)가 작동되면 이에 따라 릴레이 접점(R1)이 온되어 솔레노이드 밸브(22)를 작동시키고, 이에 따라 고정된 유압으로 붐을 조작하도록 하였기 때문에 붐의 속도 조절이 불가능하였다.That is, in the conventional boom operation, as shown in FIG. 2, when the relay 21 is operated by operating the joystick 1, the relay contact R1 is turned on to operate the solenoid valve 22 accordingly. As a result, the boom was operated with a fixed hydraulic pressure, thereby preventing the speed of the boom from being adjusted.
이에 본 발명은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로, 붐의 이동시 속도를 가변할 수 있도록 된 붐 속도 제어장치를 제공하는데 그 목적이 있다.Accordingly, the present invention has been made to solve the above problems, it is an object of the present invention to provide a boom speed control device that can change the speed during movement of the boom.
상기와 같은 목적을 달성하기 위하여 본 발명의 장치는, 작업자가 원격조정반에서 조이스틱과 속도조절자를 조작하여 붐의 이동속도를 조정할 수 있도록 된 콘크리트 펌프트럭에 있어서, 상기 속도조절자에 의해 붐의 이동 속도를 조절하기 위해 저항값이 가변되는 가변저항수단; 상기 가변저항수단의 가변된 저항값에 따라 출력전압을 조절하는 전류조절기; 및 상기 전류조절기의 출력에 따라 유압을 제어하여 붐의 이동속도를 조절하는 비례제어 솔레노이드 벨브로 이루어진 것을 특징으로 한다.In order to achieve the above object, the apparatus of the present invention, in the concrete pump truck that allows the operator to adjust the moving speed of the boom by operating the joystick and the speed controller in the remote control panel, by the speed regulator of the boom Variable resistance means for varying a resistance value to adjust a moving speed; A current regulator for controlling the output voltage according to the variable resistance value of the variable resistance means; And a proportional control solenoid valve configured to control the hydraulic pressure according to the output of the current regulator to adjust the moving speed of the boom.
즉, 본 발명은 붐의 속도를 가변시키기 위한 속도조절자를 원격조정반에 설치한 후 속도조절자의 조절에 따라 솔레노이드벨브에 인가되는 전압을 가변하여 붐의 이동속도를 조절하므로써 초기에 저속으로 이동하도록 제안할 수 있어 충돌 및 인사사고를 예방하도록 한 것이다.In other words, the present invention is to install a speed controller for varying the speed of the boom in the remote control panel and then move to a low speed initially by adjusting the moving speed of the boom by varying the voltage applied to the solenoid valve according to the control of the speed controller. It can be suggested to prevent collisions and personnel accidents.

The operator rotates the boom turning body by rotating the boom turning body by operating the lever of the operation panel, and the remote By operating the joystick of the control panel, it is possible to move each end of the boom up and down by hydraulic pressure. And the speed of conveying the boom can be adjusted by varying the variable resistance value by the control knob of the remote control panel.

붐을 이동시키기 위하여 조이스틱(1)을 조작하면 제1릴레이(2)가 여자되고, 이에 따라 타이머(3)가 작동되어 타이머접점(16K99)이 온된다. 여기서 타이머(3)는 조이스틱이 온되면 곧바로 온되고, 조이스틱이 오프되면 소정시간 경과 후 오프되어 붐의 움직임이서서히 정지되도록 한다.When the joystick 1 is operated to move the boom, the first relay 2 is excited, whereby the timer 3 is activated to turn on the timer contact 16K99. Here, the timer 3 is turned on as soon as the joystick is turned on, and is turned off after a predetermined time when the joystick is turned off, so that the movement of the boom is slowly stopped.
타이머접점(16K99)이 온되면 제2릴레이(4)가 여자되어 접점(16K274)이 온된다. 제2릴레이 접점이 온되면 가변저항(VR1)의 일단과 가변단이 전류조절기(5)의 6번단자와 7번단자에 연결된다. 이때 전류조절기의 4번과 8번단자에는 24VDC가 인가되어 있다.When the timer contact 16K99 is turned on, the second relay 4 is excited to turn on the contact 16K274. When the second relay contact is turned on, one end and the variable end of the variable resistor VR1 are connected to terminals 6 and 7 of the current regulator 5.
