본 고안은 엘리베이터 도아 개폐장치에 관한 것으로서 도아 개폐장치를 종래의 모우터구동 방식에서 쿳션유압 실린더 구동방식으로 개량하여 도아 개폐장치의 내구성 및 안정성 향상과 함께 도아 개폐장치의 시설비를 보다 저렴하게 하기 위한 것이다.The present invention relates to an elevator door opening and closing device for improving the durability and stability of the door opening and closing device by lowering the door opening and closing device from the conventional motor driving method to the cushion hydraulic cylinder driving method. will be.

종래의 엘리베이터 도아 개폐장치는 제3도에 나타난바와 같이 체인(11)에 의하여 모우터(10)에 연동되는 풀리(12)가 아이들풀리(4a)(4b)에 권취된 도아 개폐용 와이어로우프(3)를 구동시킴으로써(와이어로우프(3)는 풀리(12)에 권취되어 있음)서로 반대방향으로 구동되는 상하측 로우프(3a)(3b)가 상 하측 로우프(3a)(3b)에 각각 괘지된 양측 도아(1a)(1b) 행거(2a)(2b)를 진퇴시켜 도아(1a)(1b)가 개폐되는 구성인바, 이러한 종래의 도어 개폐장치(제3도)는 도아 개폐를 위하여 모우터( 10)를 순간적으로 정역 회전 시켜야 하므로 모우터(10)에 무리가 가서 도아 개폐장치의 잦은 고장원인이 되었으며 도어에 개폐 속도 역시 완속, 급속 완속 순으로 제어를 하여야 하였으므로 이 도아 개폐속도의 제어를 위한 전자회로(13)가 복잡할 뿐만 아니라 전자회로(13)가 작은 충격에도 쉽게 고장이 나는 폐단이 있었다.In the conventional elevator door opening and closing device, as shown in FIG. 3, a wire puller for opening and closing a door, in which a pulley 12 interlocked with a motor 10 by a chain 11 is wound around idle pulleys 4a and 4b. 3) (the wire rope 3 is wound around the pulley 12), the upper and lower ropes 3a and 3b driven in opposite directions are held on the upper and lower ropes 3a and 3b, respectively. Both doors (1a) and (1b) hangers (2a) and (b) to advance and retract the door (1a) (1b) is configured to open and close, this conventional door opening and closing device (Fig. 3) is a motor (for opening and closing the door) 10) instantaneous forward and reverse rotation of the motor (10) was a frequent cause of failure of the door opening and closing device, and the door opening and closing speed also had to be controlled in the order of slow and rapid slow down, so Not only is the electronic circuit 13 complicated, but the electronic circuit 13 This makes trouble I had evils.

따라서 본 고안은 이러한 종래의 문제점을 해결하기 위하여 도아 개폐장치를 모우터 구동방식에서 쿳션유압 실린더 구동방식으로 개량함으로써 도아 개폐장치의 구조를 간단하게 하여 도아 개폐장치의 설비 절감은 물론 도아 개폐장치의 내구성과 안정성을 보다 향상시킨 것이다.Therefore, the present invention simplified the structure of the door opening and closing device by improving the door opening and closing device from the motor driving method to the cushion hydraulic cylinder driving method to solve the conventional problems. Durability and stability are further improved.

본 고안의 구성과 작용효과를 첨부도면에 의하여 상세히 설명하면 다음과 같다.Referring to the configuration and effect of the present invention in detail by the accompanying drawings as follows.

본 고안은 아이들풀리(4a)(4b)에 와이어로우프(3)가 권취되어 상측 로우프 (3a)에 좌측도아 행거(2a)과 괘지되고, 하측 로우프(3b)에 우측 도아행거(2b)가 괘지된 구성은 종래 엘리베이터 도아 개폐장치의 구성과 동일하다.According to the present invention, the wire rope 3 is wound around the idle pulleys 4a and 4b, and the left rope hanger 2a hangs on the upper rope 3a, and the right door hanger 2b hangs on the lower rope 3b. The configuration is the same as that of the conventional elevator door opening and closing device.

본 고안은 상측 와이어 로우프(3a)에 괘지된 좌측 도아행거(2a)에 쿳션유압 실린더(5)의 피스톤로드(5b)를 연결하여 로드(5b)의 진퇴에 따라 상측 로우프(3a)와 좌측도아(1a)가 연동됨과 동시에 하측 로우프(3b)와 우측도아(1b)가 로드(5b)의 진퇴방향에 반대 방향으로 진퇴되게 하여서 된 것이다.The present invention connects the piston rod 5b of the cushion hydraulic cylinder 5 to the left door hanger 2a suspended by the upper wire rope 3a, and the upper rope 3a and the left door as the rod 5b retreats. The lower rope 3b and the right door 1b move forward and backward in the opposite direction to the forward and backward direction of the rod 5b at the same time as 1a is interlocked.

도면중의 미설명 부호(8)는 모우터(9)에 가동되는 유압펌프(8)이며 (6)는 실린더 내의 유압 제어용 파이로트 밸브(6)이고, (7)는 솔레노이드 밸브(7)이다.In the figure, reference numeral 8 denotes a hydraulic pump 8 which is operated on the motor 9, 6 denotes a pilot valve 6 for controlling hydraulic pressure in a cylinder, and 7 denotes a solenoid valve 7. .

이상과 같은 본 고안은, 유압실린더(15)의 피스톤로드(5b)의 출몰에 따라, 좌측 도아행거(5a)와 상측 와이어로우프(3a)가 일체적으로 구동되고, 하측 와이어로우프(3b)가 우칙 도아행거(2b)는 상측 와이어로우프(3a) 및 좌측도아행거(2a)와는 반대방향으로 구동됨으로써, 좌 우측 도아 (1a)(1b)가 항상 반대방향으로 구동되어 도아(1a)(1b)가 개폐되는 원리는 종래의 도아 개폐 원리와 동일하다.According to the present invention as described above, the left door hanger 5a and the upper wire rope 3a are integrally driven in accordance with the appearance of the piston rod 5b of the hydraulic cylinder 15, and the lower wire rope 3b is driven. The right door hanger 2b is driven in a direction opposite to the upper wire rope 3a and the left door hanger 2a, so that the left and right doors 1a and 1b are always driven in the opposite direction so that the doors 1a and 1b are operated. The principle of opening and closing is the same as the conventional door opening and closing principle.

본 고안은 도아(1a)(1b) 개폐용 와이어로우프(3)의 구동을 모우터(10)에 연장되는 풀리(12)에 의하여 간접구동시키는 방식을 지양하고 유압실린더(5)에 의하여 로우프(3)를 직접 구동시켜 와이어로우프(3)구동장치의 구조를 간단하게 함으로써 도어 개폐용 동력장치의 설치비를 저렴하게 하며, 도어(1) 개폐를 위한 모우터(1 0)의 정역 회전보다 유압실린더(5)의 피스톤로드(5b) 진퇴 운동이 보다 원활하고 기계적 무리가 없기 때문에 도아 개폐용 동력장치의 내구성이 향상되어 엘리베이터의 수명연장 효과를 가져올 수 있으며, 특히 도아(1)의 개폐과정에서 도아(1)에 가해지는 충격을 완화시키기 위하여 도아(1)의 개폐 속도를 조절하는 기능(도아 개폐속도의 완속 금속 완속순의 속도 변화조절)을 모우터(10)회전속도의 가, 감속 조절에 의하는 것보다는 쿳션 유압실린더(5)의 쿳션력에 의하는 것이, 보다 간단하고 기계적 무리를 초래하지 않게 되어 설비의 저렴화는 물론 내구성 향상 효과를 함께 가져올 수 있는 것이다.The present invention avoids the method of indirectly driving the driving of the wire rope 3 for opening and closing the door (1a) and (1b) by the pulley 12 extending to the motor 10. 3) by directly driving the wire rope (3) drive device to simplify the installation cost of the power unit for opening and closing the door, the hydraulic cylinder than the forward and reverse rotation of the motor (10) for opening and closing the door (1) Piston rod (5b) of (5) is more smooth and there is no mechanical force, the durability of the door opening and closing power unit is improved, which can bring the effect of extending the life of the elevator, especially in the opening and closing process of the door (1) In order to alleviate the impact applied to (1), the function of adjusting the opening / closing speed of the door 1 (controlling the speed change of the slow metal slow-down order of the door opening and closing speed) is added to the acceleration and deceleration adjustment of the motor 10. Suction hydraulic rather than By the cushioning force of the cylinder (5), it is simpler and does not cause mechanical overload, which can bring about a reduction in equipment cost and a durability improvement effect.

즉, 쿳션유압 실린더(5)의 피스톤로드(5b)가 스타트(start)할 때에는 실린더(5) 후단의 오리피스(ORIFCE)구멍(5d)을 통하여 유압이 가해짐으로써(제2도 a)유압 유입구(5e)를 통하여 유압이 정상적으로 가해지는 것(제2도 b)보다 훨씬 느린 속도로 피스톤로드(5b)의 출발이 이루어지고, 실린더(5)내에서 피스톤로드 (5b)가 정지할 지점에 다다라서는 역시 실린더(5)선단의 오리피스 구멍(5d)을 통하여 유압이 배출됨으로서(제2도 c) 유압배출구(5e)를 통하여 정상적으로 유압이 배출되는 (제2도 b)것에 비하여 훨씬 느린 속도로 피스톤로드(5b)가 멈추게 되는 것이다.That is, when the piston rod 5b of the suction hydraulic cylinder 5 starts, hydraulic pressure is applied through the orifice hole 5d at the rear end of the cylinder 5 (FIG. 2a). Through 5e, the piston rod 5b starts at a much slower speed than normally applied hydraulic pressure (Fig. 2b), and reaches the point where the piston rod 5b stops in the cylinder 5. Therefore, the hydraulic pressure is discharged through the orifice hole 5d at the tip of the cylinder 5 (Fig. 2c), and at a much slower speed than the normal discharge of pressure through the hydraulic discharge port 5e (Fig. 2b). The piston rod 5b is to be stopped.

이상과 같이 본 고안은 엘리베이터 도아(1) 구동 방식을, 모우터(10)에 연동되는 풀리(12)에 의한 간접구동 방식을 지향하고 쿳션유압 실린더(5)에 의한 직접구동 방식을 택함으로써 엘리베이터 도아(1) 개폐용 동력장치의 구조를 간단하게 하여 도아 개폐 동력장치를 설비 저렴화와 함께 내구성 향상을 가져올 수 있는 매우 실용적인 고안이다.As described above, the present invention aims to drive the elevator door 1 by an indirect driving method by the pulley 12 interlocked with the motor 10 and by adopting a direct driving method by the suction hydraulic cylinder 5. It is a very practical design that can simplify the structure of the power supply device for opening and closing the door (1) to bring the durability of the door opening and closing power device with improved equipment cost.
