본 고안은 소형 승용차의 저면 정비시 승용차의 지상으로 부터 들어올려 줌으로써 작업자가 지상에 선 상태에서 차의 저면 정비 작업을 행할수 있도록 하는 카리프트에 관한 것으로 리프트에 안전장치를 부설하여 리프트의 차 받침대 승강장치인 유압모터에 고장이 발생하거나 체인파손시에 차 받침대가 지상으로 추락하는 것을 방지함으로써 작업자의 안전을 도모한 것이다.The present invention relates to a car lift that lifts from the ground of a passenger car when the bottom of a small passenger car is maintained, so that the operator can perform the bottom maintenance work of the car while standing on the ground. The safety of the worker is promoted by preventing the car stand from falling to the ground in the event of a breakdown of the hydraulic motor, which is a lifting device, or a chain breakage.

종래에도 카리프트의 안전장치가 다수 안출되어 실용화 된 적이 있으나 종래의 카리프트 안전장치는 주로 유압모터 제어용 전자 회로 장치로서 리프트의 체인 또는 와이어 파손시에는 차 받침대의 추락을 방지 할수 없는 폐단이 있었다.In the past, many car lift safety devices have been put into practical use, but the conventional car lift safety device is mainly an electronic circuit device for hydraulic motor control, and when the chain or wire of the lift is damaged, there is a closed end that cannot prevent the fall of the car stand.

따라서 본 고안은 이러한 종래의 문제점을 해결하기 위하여 안출한 것으로 이를 첨부도면에 의하여 설명하면 다음과 같다.Therefore, the present invention has been devised to solve such a conventional problem and will be described with reference to the accompanying drawings.

본 고안은 기대(16a)의 양측단에 요입부(17)를 갖는 한쌍의 지주(16)가 입설되고 각 지주(16)의 요입부(17)내에 차 받침대(22)와 로울러(19)를 갖는 승강구(18)가 삽설되어 양측 지주(16)의 승강구(18)를 연결하는 체인(20)이 유압모터에 의해 구동되면서 양측 승강구(18)를 상, 하 승강 시키는 통상의 카리프트(15)의 구성에 있어서, 리프트(15)의 각지주(16) 내측면에 래칫기어(16b)를 형성하고, 승강구(18)에 추락방지 장치(1)를 부설하여 리프트 지주(16)의 체인(20) 파손시 추락 방지장치(1)에 의해 승강구(18)가 래칫기어(16b)에 괘지될 수 있게 한 것으로, 제2도는 이러한 승강구 추락방지 장치(1)의 분해 사시도이고, 제3도는 지주(16)에 승강구(18)와 추락방지 장치(1)를 장착한 상태의 단면을 보여 주는 것이다.According to the present invention, a pair of struts 16 having recesses 17 are placed at both ends of the base 16a, and the car support 22 and the roller 19 are inserted into the recesses 17 of each strut 16. Ordinary car lift (15) for lifting up and down both sides of the hatch 18 while the chain (20) is inserted and the chain (20) connecting the hatch (18) of both sides (16) is driven by a hydraulic motor. In the configuration, the ratchet gear 16b is formed on the inner surface 16 of the ridge 16 of the lift 15, and the fall prevention device 1 is attached to the hatch 18, so that the chain 20 of the lift support 16 is formed. ) The hatch 18 can be hooked to the ratchet gear 16b by the fall prevention device 1 in case of breakage. FIG. 2 is an exploded perspective view of the hatch fall prevention device 1, and FIG. 16 shows the cross-section of the hatch 18 and the fall prevention device 1 mounted.

즉, 좌우 한쌍의 내향 요입부(2b)와 중앙부의 외향 요입부(2c)를 갖는 케이스(2)의 통공(3)에 일측단의 레버(10)와 중앙부의 압동판(11) 및 양측의 괘지구(10)를 갖는 축지봉(6)를 축설하되, 상기 축지봉(6)의 괘지구(10)는 케이스(2)의 양측 내향 요입부(2b)에 위치하게 하고, 축지봉(6)의 압동판(11)은 케이스(2)의 외향 요입부(2c)에서 압동판(11)의 돌출부(12)가 케이스(2)의 천공부(2a)를 통하여 외부로 돌출되게 한 상태에서 압동판(11)의 상단 요입홈(11a)과 케이스(2)의 통공(4)에 스프링(14)을 괘지하여 축지봉(6)의 압동판(11) 및 양측 괘지구(10)가 전방향 으로 탄지되게 한후 이 추락방지 장치(1)를 승강구(18)에 장착하여 추락방지 장치(1)의 압동판(11)의 돌출부(12)가 케이스(2)의 천공부(2a)와 승강구(18)의 통공(18a)을 통하여 지주(16)의 체인(20)에 탄접되게 하여서 된 것이다.That is, in the through hole 3 of the case 2 having a pair of left and right inwardly recessed portions 2b and an outwardly recessed portion 2c in the center portion, the lever 10 at one end and the pressure plate 11 at the center portion and both sides The storage rod (6) having a ruled earth (10) is laid out, but the ruled earth (10) of the support rod (6) is located on both sides inwardly recessed portion (2b) of the case (2), The pressure plate 11 of) is a state in which the protrusion 12 of the pressure plate 11 protrudes outward through the perforations 2a of the case 2 from the outwardly recessed portion 2c of the case 2. The spring 14 is hung in the upper recessed groove 11a of the pressure plate 11 and the through hole 4 of the case 2, so that the pressure plate 11 and both side recesses 10 of the rod 6 are transferred. The fall prevention device 1 is mounted on the hatch 18, and the projection 12 of the pressure plate 11 of the fall prevention device 1 is provided with the perforations 2a and the hatch of the case 2. It is made to be in contact with the chain 20 of the support 16 via the through hole 18a of (18).

이상과 같은 본 고안은 체인(20)이 파손되기전 정상 상태 하에서는 받침대(22)를 갖는 승강구(18)의 하중에 의하여 체인(20)이 수직상태를 유지하기 때문에 체인(20)에 탄접된 압동판(11)에 축지봉(6)의 회전을 저지하여 축지봉(6)의 괘지구(10)가 지주(16)의 래칫기어(16b)에 괘지되는 것을 방지 함으로써 승강구(18)가 체인(20)에 견인 되어 승강자재 되나, 체인(20)의 파손시에는 체인(20)이 스프링(14)에 의해 탄지되는 축지봉 압동판(11)의 회전력을 저지할 수 없기 때문에 축지봉(6)의 압동판(11)과 함께 괘지구(10)가 회동되어 괘지구(10)가 지주(16)의 래칫기어(16b)에 괘지 됨으로써 승강구(18)의 추락을 방지하게 되는 것이다.According to the present invention as described above, since the chain 20 is maintained in a vertical state by the load of the hatch 18 having the pedestal 22 under the normal state before the chain 20 is damaged, the pressure contacted to the chain 20 is increased. The hatch 18 is prevented from hanging on the ratchet gear 16b of the support 16 by preventing rotation of the bearing rod 6 on the copper plate 11 so as to prevent the latching rod 10 of the bearing rod 6 from hanging. 20 is pulled up and lifted, but when the chain 20 is damaged, the rod 20 is not able to prevent the rotational force of the push rod 11 of the push rod 11 supported by the spring 14. The ruled earth 10 is rotated together with the pressure plate 11 of the ruled earth 10 so as to be hung by the ratchet gear 16b of the support 16 to prevent the fall of the hatch 18.

본고안중 체인(20)에 삽설된 압동돌기(21)는 압동판(11)의 슬립(SLIP)현상을 방지하기 위한 것이다.The pressing projection 21 inserted into the chain 20 in this proposal is for preventing the slip phenomenon (SLIP) of the pressing plate (11).

이상과 같이 본 고안은 카리프트(15)의 지주(16)에 래칫기어(16b)를 형성하고, 승강구(18)에 추락방지 장치(1)를 부설하여 체인(20)파손시에도 차량애 탑재된 승강구(18)의 추락을 방지할 수 있는 점에서 작업자의 안전도모에 현저한 효과가 있는 것이다.As described above, the present invention forms a ratchet gear 16b in the support 16 of the car lift 15, and installs a fall prevention device 1 in the hatch 18 to mount the vehicle even when the chain 20 is damaged. It is a remarkable effect on the safety of the worker in that the fall of the hatch 18 can be prevented.
