본 고안은 휠타입 크레인에 있어서, 고도한 조향으로 인하여 발생하는 충격을 방지하여 유압부품의 수명단축 및 운전자의 불쾌감 등을 방지하기 위한 장치에 관한 것이다.The present invention relates to an apparatus for preventing a shock caused by high steering in shortening the life of hydraulic components and the discomfort of the driver in a wheel type crane.
구체적으로는 운전자가 과도한 조향을 할 경우 바퀴프레임과 액슬이 충돌하는 위치의 바퀴프레임에 설치된 리미트스위치가 솔레노이드밸브를 작동시켜 조향실린더로 공급되는 오일을 차단시킴으로서 바퀴 프레임과 액슬이 충돌하는 것을 방지하도록 한 것이다.Specifically, if the driver makes excessive steering, the limit switch installed on the wheel frame where the wheel frame and axle collide with each other operates the solenoid valve to block the oil supplied to the steering cylinder, thereby preventing the wheel frame and the axle from colliding. It is.
일반적으로 휠타입 크레인의 조향은 운전자가 핸들을 조작하면 조향하고자 하는 조향실린더로 오일이 공급되어 바퀴프레임이 회동을 하게 되는데 핸들의 회전속도에 따라 오일의 공급속도가 결정되게 됨으로, 핸들을 너무 많이 회전시키게 되면 바퀴프레임과 액슬이 충돌하게 되고, 바퀴프레임과 액슬이 접촉한 후에는 더 이상의 조향이 이루어지지 않으므로 조향을 위한 유압 라인의 압력이 상승되어 릴리이프 밸브를 통해 탱크로 귀한되도로 하였다.In general, the steering of wheel type crane is when oil is supplied to the steering cylinder to be steered when the driver operates the steering wheel, and the wheel frame is rotated. The oil supply speed is determined according to the rotation speed of the steering wheel. When rotated, the wheel frame and the axle collide, and after the wheel frame and the axle are in contact with each other, no further steering takes place, and the pressure of the hydraulic line for steering is increased, which leads to the tank through the relief valve.
따라서, 동력의 손실이 발생하였으며, 유압부품에 무리한 힘이 가해지므로 유압부품의 수명이 단축되었다.Therefore, a loss of power occurs, and an excessive force is applied to the hydraulic component, thereby shortening the life of the hydraulic component.
본 고안은 상기와 같은 폐단을 제거하기 위하여 안출된 것으로서, 바퀴프레임과 액슬이 충돌하는 것을 방지하여 부품의 손상을 방지하고, 운전자의 승차감을 향상시키며, 불필요한 동력의 손실을 방지하는데 목적이 있다.The present invention is devised to remove the closed end as described above, to prevent the wheel frame and the axle from colliding to prevent damage to the parts, improve the ride comfort of the driver, and to prevent unnecessary loss of power.
상기 목적을 달성하기 위한 본 고안의 특징은 바퀴프레임에 리미트 스위치를 장착하여 조향실린더의 오일공급라인에 설치된 솔레노이드 밸브에 연결한 것으로서 이하 첨부된 도면에 의거하여 본 고안의 구성을 상세히 설명하면 다음과 같다.Features of the present invention for achieving the above object is to be equipped with a limit switch on the wheel frame connected to the solenoid valve installed in the oil supply line of the steering cylinder as follows in detail the configuration of the present invention in accordance with the accompanying drawings same.
제1도는 본 고안의 유압회로도로서, 오르비트롤 모터(1)로 부터 공급되는 오일이 조향 솔레노이드 밸브(2)(2′)에 의해 조향이 되도록한 휠타입크레인의 조향장치에 있어서, 로터리 조인트(3)와 상기 조향 솔레노이드 밸브(2′)사이 및 로터리 조인트(3)와 조향 실린더(4)(4′)사이에 각각 솔레노이드 밸브(8)(8′)를 설치하되, 상기 솔레노이드 밸브(8)(8′)는 바퀴프레임(10)에 설치된 리미트 스위치(9)(9′)와 연결한다.1 is a hydraulic circuit diagram of the present invention, in which a wheel type crane steering apparatus in which oil supplied from an orbitrol motor 1 is steered by a steering solenoid valve 2 (2 '), 3) and solenoid valves 8 and 8 'between the steering solenoid valve 2' and between the rotary joint 3 and the steering cylinder 4 and 4 ', respectively, wherein the solenoid valve 8 8 'is connected to the limit switches 9 and 9' installed on the wheel frame 10.
그리고, 상기 리미트 스위치(9)(9′)는 제2도에 도시한 바와같이 핸들(14)에 장착된 버튼스위치(11)에 연결하여 전원(12)에 연결한다.The limit switches 9 and 9 'are connected to the power source 12 by connecting to the button switch 11 mounted on the handle 14 as shown in FIG.
미설명 부호 5는 릴리이프 밸브, 6는 펌프, 7은 탱크, 13은 액슬이다.5 is a relief valve, 6 is a pump, 7 is a tank, and 13 is an axle.
상기와 같이 구성된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention configured as described above are as follows.
오르비트롤 모터(1)로 부터 오일이 조향실린더(4)(4′)로 공급이 되면 바퀴프레임이 회동을 하기 시작한다.When oil is supplied from the orbitrol motor (1) to the steering cylinder (4) (4 '), the wheel frame starts to rotate.
그런데, 운전자가 핸들(14)을 너무 많이 회전시켜 바퀴프레임(10)의 리미트스위치(9)(9′)가 액슬(13)에 접촉하게 되면 솔레노이드 밸브(8)(8′)에 전원이 인가되어 상기 솔레노이드 밸브(8)(8′)를 위치이동시켜 조향실린더(4)(4′)로 공급되던 오일을 탱크(7)로 드레인 시킨다.However, if the driver rotates the handle 14 too much and the limit switches 9 and 9 'of the wheel frame 10 come into contact with the axle 13, the power is applied to the solenoid valves 8 and 8'. Thus, the solenoid valve 8 (8 ') is moved to drain the oil supplied to the steering cylinder (4) (4') to the tank (7).
따라서, 조향실린더(4)(4′)로 오일이 공급되지 않으므로 바퀴프레임(10)과 액슬(13)이 충돌되는 것을 방지할 수 있고, 솔레노이드밸브(8)(8′)에 의해 유압라인에 발생될 수 있는 오일의 승압을 방지할 수 있으므로 부품의 손상을 방지하고 승차감을 향상시킬 수 있다.Therefore, since oil is not supplied to the steering cylinders 4 and 4 ', the wheel frame 10 and the axle 13 can be prevented from colliding with each other, and the solenoid valves 8 and 8' are connected to the hydraulic line. It is possible to prevent the boost of oil that can be generated, thereby preventing damage to the parts and improving ride comfort.
그와 같은 상태에서 반대 방향으로 조향을 하고자 할 경우에는 핸들(14)에 부착된 버튼 스위치(11)를 ON 시키게 되면 솔레노이드 밸브(8)(8′)에 인가된 전원이 차단되므로 다시 조향실린더(4)(4′)로 오일을 공급할 수 있는 상태가 된다.In such a state, if steering is to be performed in the opposite direction, when the button switch 11 attached to the handle 14 is turned on, the power applied to the solenoid valves 8 and 8 'is cut off. 4) The oil can be supplied to (4 ').
따라서 반대방향으로 핸들(14)을 회전시키면 압압됐던 리미트스위치(9)(9′)가 해제되면서 바퀴프레임(10)이 회동을 하게 되므로 다음 동작을 할 수 있게 된다.Therefore, when the handle 14 is rotated in the opposite direction, the wheel frame 10 is rotated while the limit switch 9 (9 ') that is pressed is released, thereby enabling the next operation.
상기와 같은 본 고안의 부품의 파손을 방지하고 승차감을 향상시킬 수 있으며, 불필요한 동력의 손실을 방지할 수 있는 효과가 있는 고안인것이다.To prevent damage to the components of the present invention as described above and to improve the riding comfort, it is the devised effect that can prevent the loss of unnecessary power.
