본 고안은 수직 지지대에 지지되는 리프트판을 구동장치의 구동에 따라 승강시키는 차량정비용 리프트(LIFT)에 관한 것으로서 특히 구동장치의 급격한 유압 저하 등에 의하여 와이어 로프에 이완이 발생하거나 또는 끊어지는 등의 사고가 발생할 경우에 리프트판의 하강을 정지시켜 안전사고의 발생을 미연에 방지하는 차량정비용 리프트의 안전장치에 관한 것이다.The present invention relates to a vehicle fixed-cost lift (LIFT) for elevating the lift plate supported on the vertical support in accordance with the drive of the drive device, in particular, such as loosening or breaking of the wire rope due to a sudden drop in hydraulic pressure of the drive device The present invention relates to a safety device for a fixed cost vehicle lift that prevents the occurrence of a safety accident by stopping the lowering of the lift plate when an accident occurs.

일반적으로 차량정비용 리프트에서 리프트판을 승강시키는 와이어로프 또는 체인등에는 충분한 안정율을 부여하여 제조하고 있으나, 구동장치의 급속한 유압의 감소로 인한 와이어로프의 이완이나 또는 장기간 사용함에 따라 와이어로프의 끊어짐이 발생할 경우에 리프트판이 급속히 하강하여 안전사고가 발생하게 되므로 안전장치를 설치하여 리프트판의 급속한 하강을 방지하고 있다.Generally, the wire rope or chain that lifts the lift plate in the fixed-cost lift is manufactured with sufficient stability rate, but the wire rope is loosened due to the rapid decrease of hydraulic pressure of the driving device or long-term use. When the break occurs, the lift plate descends rapidly and a safety accident occurs, so a safety device is installed to prevent the rapid fall of the lift plate.

따라서, 리프트의 안전장치로서는 여러가지가 제안 및 사용되고 있는 것으로, 그 일예를 들면, 대한민국 실용신안 공고공보 제92-1837호에 나타나 있다.Accordingly, various safety devices for lifts have been proposed and used, and are shown in, for example, Korean Utility Model Publication No. 92-1837.

이 종래의 기술은 리프트판과 수직 지지대 간에 연결되는 리프트판의 승강안내부에, 와이어로프의 이완 및 끊어짐이 발생할 경우에 회전하는 회전부재를 설치하고, 이 회전부재에는 안전구멍을 천공한 후 수직으로 입설되는 안전봉을 삽입하여 와이어로프의 이완 및 끊어짐이 발생하지 않았을 경우에 안전구멍이 수평을 이루면서 리프트판이 원활하게 승강되게 하고 와이어 로프의 이완이나 끊어짐이 발생할 경우에는 안전구멍이 수평을 이루면서 리프트판이 원활하게 승강되게 하고 와이어 로프의 이완이나 끊어짐이 발생할 경우에는 안전구멍이 경사지면서 회전부재가 안전봉에 걸려 리프트판의 하강이 정지되게 구성하였다.This conventional technique installs a rotating member that rotates when the wire rope is loosened and broken, in the lifting guide of the lift plate connected between the lift plate and the vertical support, and after the safety hole is drilled, When the safety rod is inserted into the wire rope, if the wire rope is not loosened or broken, the safety plate is leveled and the lift plate is smoothly lifted. If the wire rope is loosened or broken, the safety plate is horizontal and the lift plate is horizontal. When the lifting and lowering of the wire rope is caused to smoothly rise and fall, the safety hole is inclined while the rotating member is caught by the safety rod is configured to stop the falling of the lift plate.

그러나 리프트판의 승강을 반복함에 따라 안전구멍과 안전봉간의 접촉으로 상호간에 마모가 발생하여 안전봉의 직경보다 안전구멍의 내경이 커지게 되고, 이로 인하여 와이어로프가 끊어졌을 경우에 안전구멍이 경사짐에도 불구하고 회전부재가 안전봉에 걸리지 못하고, 리프트판이 그대로 하강하여 안전사고가 발생하게 되는 등의 여러가지 문제점이 있었다.However, as the lift plate is repeatedly raised and lowered, the contact between the safety hole and the safety bar causes abrasion between each other, and the inner diameter of the safety hole becomes larger than the diameter of the safety bar, which causes the safety hole to be inclined when the wire rope is broken. And there was a variety of problems, such as the rotating member does not catch the safety rod, the lift plate is lowered as it is, a safety accident occurs.

본 고안은 상기와 같은 종래 기술의 제반 문제점을 해결하기 위하여 안출한 것으로서, 와이어로프가 끊어졌을 경우에 회전하는 회전부재에 편심캠을 설치하고, 편심캠의 외측에는 안전레일을 설치하여 와이어로프가 끊어졌을 경우에 회전부재의 편심캠이 회전되면서 안전레일에 밀착되어 리프트판의 하강이 정지되도록 함으로써 장기간 사용하여도 마모됨이 없고, 사고의 발생시 정확하게 동작하는 안전장치를 제공하는 데 그 목적이 있는 것으로 이를 첨부된 도면을 참조하여 상세히 설명한다.The present invention has been devised to solve the above problems of the prior art, and when the wire rope is broken, the eccentric cam is installed on the rotating member, and the safety rail is installed on the outside of the eccentric cam to break the wire rope. In this case, the eccentric cam of the rotating member is in close contact with the safety rail, so that the lowering of the lift plate is stopped. It will be described in detail with reference to the accompanying drawings.

제1도는 본 고안의 안전장치가 구성된 차량정비용 리프트의 전체 구성을 보인 사시도이다. 여기서, 부호1은 리프트의 받침대로서 받침대(1)의 네 모서리에는 수직 지지대(2)가 입설되고, 일측의 수직 지지대(2)에는 리프트의 동작을 제어하는 제어장치( 3)가 설치되어 있다.1 is a perspective view showing the overall configuration of a vehicle maintenance lift configured with a safety device of the present invention. Here, reference numeral 1 denotes a pedestal of the lift, and vertical supports 2 are placed at four corners of the pedestal 1, and a control device 3 for controlling the operation of the lift is provided on the vertical support 2 on one side.

부호 4는 4개의 수직지지대(2)의 사이에 설치되어 승강되는 리프트판이다. 이 리프트판(4)은 2개의 전방 수직 지지대(2)와, 2개의 후방 수직 지지대(2)에 수평 지지대(5)가 승강 안내부(6)로 연결되고, 2개의 수평 지지대(5)에는 발판(7)이 고정되어 정비할 차량이 올라가며, 발판(7)의 사이에는 유압에 의해 구동되는 승강장치(8)가 설치되어 발판(7)에 올라간 차량의 타이어 교체등을 할 경우에 차량을 승강시키게 되어 있다.Reference numeral 4 is a lift plate which is installed and lifted between the four vertical supports (2). The lift plate 4 has two front vertical supports 2 and two rear vertical supports 2 with a horizontal support 5 connected to a lift guide 6 and two horizontal supports 5. When the foothold 7 is fixed and the vehicle to be maintained rises, a lift device 8 driven by hydraulic pressure is installed between the footholds 7 to replace the tire when the tire of the vehicle mounted on the foothold 7 is replaced. It is supposed to be elevated.

또한 상강 승강 안내부(6)는, 제2도에 도시된 바와 같이 수평 지지대(5)의 단부에 2개의 브래키트(9)를 별도의 거정수단으로 고정하여 수직 지지대(2)의 내측으로 삽입하고, 브래키트(9)의 사이에는 로울러(10)를 설치하여, 일단은 수직 지지대(2)의 상부에 고정되고 타단은 구동장치(도면에 도시되지 않았음)의 측에 연결되어 구동장치의 구동에 따라 리프트판(4)을 승강시키는 와이어로프(11)의 이송을 안내하게 되어 있다.In addition, the elevating guide portion 6 is inserted into the vertical support 2 by fixing the two brackets (9) to the end of the horizontal support (5) by a separate fixing means as shown in FIG. The roller 10 is installed between the brackets 9, one end of which is fixed to the upper portion of the vertical support 2, and the other end of which is connected to the side of the driving device (not shown). The driving of the wire rope 11 for elevating and lifting the lift plate 4 is guided.

또한 부호12는 본 고안의 안전장치의 요부인 하강 정지수단이다.In addition, reference numeral 12 is a descent stop means that is the main part of the safety device of the present invention.

이 하강 정지수단(12)은 제3도에 도시된 바와 같이 축봉(13)을 구비한 2개의 편심캠(14)을 상호 연결함과 어울러 링크(15)의 일단을 고정하고, 두 링크(15)의 타단 사이에는 로울러(16)를 설치하며, 링크(15)의 타단 외측에는 축핀(17)을 고정 설치하였다.The lowering stop 12 is fixed to one end of the link 15, in conjunction with the interconnection of the two eccentric cam 14 with the shaft 13, as shown in FIG. The roller 16 was provided between the other ends of 15), and the shaft pin 17 was fixedly installed in the outer side of the other end of the link 15. As shown in FIG.

이와 같이 된 하강 정지수단(12)은 상기 브래키트와 로울러(10)와의 사이에 와이어로프(11)를 개재하여 축봉(13)으로 설치되고, 축핀(17)의 일측과 브래키트(6)의 적소에는 스프링(18)이 설치되어 현수체(11)의 이완 및 절단시 로울러(16)가 로울러(10)의 축봉(13)을 중심으로 회전되게 하였다.The lowering stop means 12 as described above is installed as a shaft bar 13 via a wire rope 11 between the bracket and the roller 10, and one side of the shaft pin 17 and the bracket 6 A spring 18 is installed in place to allow the roller 16 to rotate about the shaft 13 of the roller 10 when the suspension 11 is relaxed and cut.

그리고 하강 정지수단(12)의 외측에는 하강 정지수단(12)의 회전시 편심캠(14)이 회전되면서 밀착되는 안전레일(19)이 수직 입설되고, 브래키트(9)의 단부에는 이탈방지판(20)이 고정되어 안전레일(19)의 이탈을 방지하게 구성된다.And the safety rail 19 which is in close contact with the eccentric cam 14 is rotated during the rotation of the down stop means 12 is vertically installed on the outside of the down stop means 12, the separation prevention plate at the end of the bracket (9) 20 is fixed and configured to prevent the departure of the safety rail (19).

이와 같이 구성된 본 고안의 안전장치는 차량의 정비 등을 실시할 경우에는 차량의 리프트판(4)의 발판(7)놓고 미 도시된 구동장치를 구동시켜 와이어로프(11)를 당기도록 함에 따라 리프트판(4)이 상승되고, 구동장치를 상기와는 반대방향으로 구동시킴에 따라 리프트판(4)이 하강하는 것으로, 구동장치의 구동에 따라 정비할 차량을 승강시키게 된다.When the safety device of the present invention configured as described above is carried out when the maintenance of the vehicle, etc. lifts the wire rope 11 by pulling the wire rope 11 by driving the driving device (not shown) of the lift plate 4 of the vehicle. As the plate 4 is raised and the driving device is driven in the opposite direction to the above, the lift plate 4 is lowered, thereby raising and lowering the vehicle to be maintained according to the driving of the driving device.

이때, 구동장치의 급격한 유압감소로 인한 와이어로프(11)의 이완이나 끊어짐이 발생하지 않을 경우에는 제4도에 도시된 바와 같이 와이어로프(11)에 의해 정지수단(12)이 실선과 같이 회동하지 못하게 된다.At this time, when the wire rope 11 is not loosened or broken due to a sudden decrease in hydraulic pressure of the driving device, as shown in FIG. 4, the stop means 12 is rotated by a solid line as shown by the wire rope 11. You won't be able to.

그러므로 편심캠(14)이 회동되지 않아 하강정지수단(12)의 편심캠(14)이 안전레일(19)에 밀착되지 않게되고 이로 인하여 리프트판(4)은 아무런 방해도 받지 않고, 구동장치의 구동에 따라 정상으로 승강된다.Therefore, the eccentric cam 14 is not rotated so that the eccentric cam 14 of the descending stop means 12 does not come into close contact with the safety rail 19. As a result, the lift plate 4 is not disturbed. According to the driving, it is elevated to normal.

그리고 구동장치의 급격한 유압감소로 인한 와이어로프(11)의 이완이나 끊어짐이 발생할 경우에는 일단은 축핀(17)과 타단은 승강안내부(6)에 설치된 스프링(18)에 의해 하강 정지수단(12)이 회전하게 되므로 하강정지수단(12)의 편심캠(14)이 제4도의 실선에서 화살표방향인 가상선과 같이 회동하여 안전레일(19)에 밀착되는 동시에 이 안전레일(19)은 또한 이탈방지판(20)에 밀착되므로 이로 인하여 리프트판(4)의 하강을 시키게 하는 것이다.When the wire rope 11 is loosened or broken due to a sudden decrease in hydraulic pressure of the driving device, one end of the lowering stop means 12 is stopped by the spring 18 provided on the shaft pin 17 and the other end of the lifting guide 6. Since the eccentric cam 14 of the descending stop means 12 is rotated like a virtual line in the direction of the arrow in the solid line of FIG. 4 to be in close contact with the safety rail 19, the safety rail 19 is also prevented from being separated. Since it is in close contact with the plate 20 thereby causing the lift plate 4 to descend.

한편 상기에서는 4개의 수직지지대를 구비하고 있는 4주식 차량정비용 리프트를 예로 들어 본 고안의 안전장치를 설명하였으나, 본 고안을 실사함에 있어서는 2개의 수직 지지대만을 구비하고 있는 2주식 차량정비용 리프트에 간단히 설치하여 구현할 수도 있다.On the other hand, the safety device of the present invention has been described by taking a four-vehicle fixed cost lift having four vertical supports as an example, but the two-vehicle fixed cost lift having only two vertical supports in the present invention It can also be installed and implemented in.

이상에서 상세히 설명한 바와 같이 본 고안은 와아어로프의 이완이나 끊어짐이 발생할 경우에 하강 정지수단이 작동하여 순간적으로 리프트판의 하강을 정지시키게 되므로 장기간 사용하여 마모가 발생하여도 와이어로프의 이완 및 끊어짐 등이 발생할 경우에 리프트판의 하강을 안전사고의 발생을 방지할 수 있는 효과가 있다.As described in detail above, the present invention stops the lowering of the lift plate by operating the lowering stop means when the relaxation or breakage of the war rope occurs. When the back occurs, the lowering of the lift plate has the effect of preventing the occurrence of a safety accident.
