Description

트랙터 정비용 리프트 { Tractor overhauling lift }Tractor overhauling lift}

농업의 첨단 기계화로 트랙터의 보유현황이 날로 확산됨에 따라 트랙터의 작업환경에 대한 문제점이 대두되고 있다.Due to the advanced mechanization of agriculture, the current situation of tractors has been spreading, and the problem of the working environment of tractors has emerged.

본 발명은 트랙터의 기계 정비 · 수리 작업에 따른 문제점에서 개발되었으며 농기계 정비 작업에 목적을 두고 있으며, 트랙터 정비작업의 작업환경에 안전성과 효율성을 극대화시키는 기술이다.The present invention has been developed in the problems according to the mechanical maintenance, repair work of the tractor and aims at the maintenance work of agricultural machinery, a technique for maximizing safety and efficiency in the working environment of tractor maintenance work.

트랙터의 하부 수리 시 본체의 감량을 고정시키기 위한 방안으로 사용되었던 기존의 수동 잭(jack)이나 고임목을 고이는 방식과 자동차에 맞춘 리프트를 사용할 때 트랙터 구조상에서 오는 불편함과 위험성에서 창안되었으며 자동차 또한 본 발명의 리프트 사용이 가능하도록 하였다.It was invented from the inconvenience and risks of the tractor structure when using the conventional manual jack or the method of fastening the dead wood, which is used as a way to fix the weight loss when repairing the lower part of the tractor, and the lift that fits the car. It was possible to use the lift of the invention.

본 발명은 기존의 수동 잭이나 고임목에 비해 다소 부피감은 있으나 유압 실린더로 연결된 수동 레버(s.w)를 사용하여 작업환경의 안전성으로 편리한 작업을 할 수 있다. 중량감이 높은 트랙터 정비 · 수리 시 위험 요소가 많은 기존의 기술에서 비롯된 트랙터의 고정상태의 불안정으로 작업환경의 위험을 극소화시킬 수 있으며, 투여되는 인력을 최소 1/3가량으로 줄여 효율적인 정비작업으로 인한 작업 능률을 크게 향상시키는데 있다.The present invention is a little bulky compared to the conventional manual jack or wood, but using a manual lever (s.w) connected by a hydraulic cylinder can be a convenient operation in the safety of the working environment. Tractor maintenance with high weight can minimize the risk of working environment due to the instability of the fixed position of the tractor, which is derived from the existing technology, which has many risk factors. It is to greatly improve work efficiency.

본 발명은 기계 정비 및 해체작업을 손쉽게 하도록 트랙터 정비용 리프트 장치에 관한 것이다. 본 발명을 지상 설치하여 기계 탑재시 안전한 상승 및 하강으로 안전한 작업 자세로 작업환경을 개선하는데 있다.The present invention relates to a tractor maintenance lift device to facilitate machine maintenance and dismantling. The present invention is installed on the ground to improve the working environment in a safe working posture by safe ascent and descent when the machine is mounted.

본 발명의 구조를 크게 나누어 보면 유압 컨트롤 박스(control box)의 동력을 연결한 리프트(rift) 본체로 이루어져 있다. 유압 컨트롤 박스에는 전동 모터의 힘의 동력을 유압 펌프의 감속 장치로 감속하여 저장 탱크속의 유압 유가 일정한 속도로 순환하도록 사용하였다. 이에 순환된 유압 유는 유압 호스관을 통해 4개의 컨트롤 레버(s.w)를 수동 동작할 수 있도록 전달되게 하였다.The structure of the present invention can be broadly divided into a lift body connected to a power of a hydraulic control box. In the hydraulic control box, the power of the electric motor was reduced by the deceleration device of the hydraulic pump so that the hydraulic oil in the storage tank circulated at a constant speed. The hydraulic oil circulated there was to be delivered to the manual control of the four control levers (s.w) through the hydraulic hose pipe.

리프트 본체는 철제 사다리꼴의 모양으로 가장자리 윤곽에 따라 전체 레일을 설치하였다. [ 도 1 ] 를 참안하여 그 위에 상하 이동이 가능하도록 바퀴를 부착한 4개의 받침 지지대가 2개씩 쌍을 이루는 방식(①②, ③④)으로 각각 작은 레일을 추가 설치하여 트랙터 탑재시 간격을 자유롭게 이동할 수 있도록 하였다. 트랙터 외형에 충실하여 앞축 바퀴와 뒤축 바퀴 간격 차이를 고려해 받침 지지대간의 상하이동 폭에 차등(70cm∼100cm이하)을 두었다.The lift body has a steel trapezoidal shape, and the entire rail is installed along the edge contour. 1, the four rail supports attached to the wheel so that the vertical movement can be moved on top of each other in a paired manner (①②, ③④) by installing a small rail each can be moved freely when mounting the tractor It was made. Faithful to the shape of the tractor, a differential (less than 70 cm and less than 100 cm) was placed in the shanghai-dong width between the support bases, taking into account the difference between the front and rear wheels.

[ 도 1 ] 을 참고하여 자동차와는 다른 트랙터 구조를 고려하여 (②,③)번 받침 지지대의 바퀴를 큰 레일부분에 고정하여 균형점을 잡게 하였으며 (①,④)번 받침 지지대로 하여금 간격 조절이 가능한 것에 큰 장점을 가진다.[Fig. 1] by considering the tractor structure different from the car, the wheels of the support bases (②, ③) were fixed to the large rail part to set the balance point. (①, ④) It has great advantages over what is possible.

또한 [ 도 2 ] 와 같이 트랙터와 받침 지지대의 부위를 고려하여 받침 지지대의 길이를 추가로 넓힐 수 있도록 조절 가능(120cm∼140cm)하게 하였다.In addition, in consideration of the tractor and the support portion as shown in Figure 2 it was made to be adjustable (120cm ~ 140cm) to further expand the length of the support.

기기의 탑재 상승시 매우 빠른 속도로 순환하는 유압 유에 따른 위험요소를 방지하기 위해 유압 펌프의 감속 장치를 이용해 일정한 유압 유가 흐르도록 하였다. 그리고 고정된 기기의 무게를 유지할 수 있도록 2개의 안전 장치( 안전 밸브 장치, 안전 고정핀)를 설치하였는데, 먼저 유압 실린더의 관에 부착한 안전 밸브를 수동으로 작용하여 고정된 높이를 유지하도록 도왔다. 안전 고정핀은 탑재 기기의 무게에 따라 일정한 거리에 자동으로 'ㄱ'자인 핀이 안착되도록 하는 스프링의 원리를 적용하였다. 올려진 차제의 무게에 의해 차체가 추락하거나 급 · 하강되지 않도록 유압 실린더의 유압 공급 관에 2중 안전 밸브의 부착으로 안전성에 중점을 두었다.In order to prevent the danger caused by the hydraulic oil circulating at a very high speed when mounting the device, a constant hydraulic oil was flowed by using a reduction device of the hydraulic pump. In addition, two safety devices (safety valve device and safety pin) were installed to maintain the weight of the fixed device. First, the safety valve attached to the tube of the hydraulic cylinder was manually operated to maintain the fixed height. The safety fixing pin adopts the principle of the spring which allows the 'A' design pin to be settled automatically at a certain distance according to the weight of the loaded device. Safety is emphasized by attaching a double safety valve to the hydraulic supply line of the hydraulic cylinder so that the body does not fall or drop due to the weight of the raised vehicle.

본 발명은 무게 적재량이 매우 큰 농업용 트랙터 정비 · 수리시 작업의 안정성과 능률성을 크게 향상시킨다. 종래의 방법으로 불안정한 고임 기술에서 작업자가 다칠 수 있는 사고의 위험률을 낮추어 좀더 안전한 작업 환경을 가능하게 한다.The present invention greatly improves the stability and efficiency of work during maintenance and repair of agricultural tractors with a very large weight loading. The conventional method lowers the risk of accidents that can injure workers in unstable pooling technology, thereby enabling a safer working environment.

자동차와는 달리 바퀴간의 간격이 일정치 않은 구조의 트랙터에 기안하여 바퀴간의 편차를 위해 받침 지지대간의 간격에 차등을 두었다. 앞측 바퀴가 뒤축 바퀴보다 폭이 작음을 고려하여 리프트 받침 지지대의 상 · 하 이동폭에 (70cm∼100cm)가량의 차등을 두었다. 또한 대형 트랙터를 들어올려 받칠 때 받침대의 길이를 연장시킬 수 있도록 2중 받침 지지대를 설치하여 작업의 안전과 효율을 높였다. 한편 자동차에 리프트 적용 또한 가능하다.Unlike automobiles, the tractors are designed with a non-uniform wheel structure, and the gap between the support bases is differentiated for the wheel deviation. Considering that the front wheel is smaller than the heel wheel, a difference of about 70cm to 100cm is placed on the up and down movement of the lift support. In addition, a double support system was installed to extend the length of the support when lifting a large tractor to increase safety and efficiency. On the other hand, it is also possible to apply a lift to a car.

중량감이 높은 트랙터에 고려해 레일 부착으로 거리 이동이 작업자로 하여금 자유롭게 조절 가능하게 하여 작업의 능률을 높이는 것에 가장 큰 탁월성을 갖는다.Considering the tractor with a heavy weight, the rail attachment allows the operator to adjust the distance freely, which is the most excellent in increasing the work efficiency.
