미설명부호 5는 마스트에 기립상태로 부착된 랙이다.Reference numeral 5 is a rack attached to the mast in an upright position.

이와같이 구성된 본 고안의 작용 및 효과를 설명하면 다음과 같다.Referring to the operation and effects of the present invention configured as described above are as follows.

즉, 본 고안은 제1도 내지 제3도에서 도시한 바와같이 고층건물을 짓기위한 건설현장에 마스트의 랙(5)과 적재함(도면에 도시되어있지않음)에 부착된 승강기용 안전제동장치의 피니언(32)이 맞물려서 구동장치의 모우터(도면에 도시되어있지않음)에 따라 회전하게 되는데, 상기 모우터의 브레이크고장으로 적재함이 급하강하므로 인하여 상기 피니언(32)의 회전수가 설정된 회전수를 초과회전하게 되면, 샤프트(33)에 고정된 캠(31)의 윙(36)이 회전력에 의하여 캠(31)의 관통홀(31a)과 절곡바아(34)의 돌턱(34a)사이에 개재된 코일스프링(35)이 압축되면서 윙(36)의 단부로 브레이크부(20)에 마련된 프릭션콘(22)의 걸림턱(25)에 걸리게 된다.That is, the present invention provides a safety brake device for an elevator attached to a rack 5 of a mast and a loading box (not shown) as shown in FIGS. 1 to 3. The pinion 32 is engaged and rotates according to the motor (not shown in the drawing) of the driving device, and the load of the pinion 32 is lowered due to the sudden drop of the brake breaker of the motor. When over-rotating, the wing 36 of the cam 31 fixed to the shaft 33 is interposed between the through-hole 31a of the cam 31 and the stone projection 34a of the bending bar 34 by the rotational force. As the coil spring 35 is compressed, the end of the wing 36 is caught by the engaging jaw 25 of the friction cone 22 provided in the brake unit 20.

(제2도의 가상선참조)(See virtual line in Figure 2.)

이때, 윙(36)의 단부가 걸림턱(25)에 걸리면서, 샤프트(33)에 고정된 피니언(32)의 회전을 순간적으로 감속 회전시킴과 동시에 브레이크부(20) 나선축(21)에 끼워진 탄성수단수용부재(42)가 나선축(21)의 회전에 따라 접시형 판스프링(41a) 또는 코일스프링(41b)으로된 탄성수단부재(41)를 압축시키면서 프릭션콘(22)의 브레이크링(23)이 하우징(10)의 브레이크링(11)에 밀착제동될때, 탄성수단수용 부재(42)의 하단부가 하우징(10)의 내면에 설치된 리미트스위치(12)를 터치시킴과 동시에 전원을 끊어지게하면서 제동은 완료된다.At this time, while the end portion of the wing 36 is caught by the locking jaw 25, the rotation of the pinion 32 fixed to the shaft 33 is instantaneously reduced and rotated, and the brake portion 20 is inserted into the spiral shaft 21. Brake ring of friction cone 22 while compressing elastic means member 41 made of plate-shaped leaf spring 41a or coil spring 41b in accordance with rotation of spiral shaft 21. When 23 is tightly braked to the brake ring 11 of the housing 10, the lower end portion of the elastic means accommodation member 42 touches the limit switch 12 installed on the inner surface of the housing 10 and cuts off the power. Braking is completed.

그리고, 상기와 같이 제동이 완료된 상태에서 제동을 풀고자할때에는 하우징(10)의 커버(14)를 풀어서 해체한 다음에 탄성수단부용부재(42)와 브레이크부(20)의 나선축(21)과의 사이에 압축된 접시형 판스프링(41a) 또는 코일스프링(41b)으로된 탄성수단부재(41)를 완화시키기위하여 나선축(21)에서 탄성수단수용부재(42)를 수동으로 풀게되면, 탄성수단부재(41)에 의해 밀려나면서 탄성수단수용부재(42)의 하단부가 리미트스위치(12)를 원상복위시킴과 동시에 전원이 연결된다.Then, when the braking is completed in the state of braking as described above, the cover 14 of the housing 10 is released and dismantled, and then the spiral shaft 21 of the elastic means portion member 42 and the brake portion 20 is removed. When the elastic means accommodating member 42 is manually released from the spiral shaft 21 in order to alleviate the elastic means member 41 made of the plate-shaped leaf spring 41a or the coil spring 41b compressed therebetween, While being pushed by the elastic means member 41, the lower end portion of the elastic means accommodation member 42 restores the limit switch 12 to its original state and is connected to a power source.

그다음에 하우징(10)에 커버(14)를 조립하여 업스위치(도면에 도시되어있지않음)넣어 적재함을 상승시키게되면, 윙(36)의 단부와 프릭션콘(22)의 걸림턱(25)이 맞물려있는 상태에서 역회전하게되므로 코일스프링(35)의 탄성력에 의해 제2도의 실선과 같이 원상복귀될때, 다운스위치(도면에 도시되어있지않음)을 넣어서 하강시키면 되는 것이다.Then, assembling the cover 14 to the housing 10 to put the up switch (not shown in the figure) to raise the loading box, the end of the wing 36 and the locking jaw 25 of the friction cone 22 Since the reverse rotation in the engaged state when the return to the original by the elastic force of the coil spring 35 as shown in the solid line of Figure 2, the downswitch (not shown in the figure) is put down.

이와같이 된 본 고안은 종래의 승강기용 제동장치와는 달리, 하우징(10)내에 내장되는 브레이크부(20)의 양측으로 각각 캠부(30)와 탄성수단부(40)를 비교적 간단한 관련구성으로 하여 적재함의 급하강을 방지하면서 용이하게 정지시킴에 의해 인면피해방지와 적재화물 및 적재함파손을 방지하는 작용효과가 있는 것이다.Unlike the conventional brake device for elevators, the present invention has a cam unit 30 and an elastic means unit 40 mounted on both sides of the brake unit 20 embedded in the housing 10 in a relatively simple related configuration. By stopping easily while preventing the descent, there is an action effect to prevent face damage and prevent damage to the cargo and load.
