Abstract

A brake system of a lighting tower is provided to prevent the danger due to the sudden drop of the lighting tower. A lighting tower hangs on an elevation wire and moves up and down an electric pole(1). Cams(24,24a) is rotated by the sudden rotation of the lighting tower lifting guide rollers(20,20a). The rotation of cam operates cam levers(26,26a), load lever gusset plates(28,28a), and a latch(19). A downstream catching teeth(16a) of a stopper(16) is engaged to a ratchet gear(15). The movement of slide boards(13,13a) stops. The sudden drop of the lighting tower is prevented by stopping the rotation of the lighting tower lifting guide roller.

Description

승강식 조명탑의 안전브레이크 장치 {Braker equipment of lighting tower}Safety brake device for lifting light towers {Braker equipment of lighting tower}

본 발명은 승강식 조명탑의 안전브레이크 장치에 관한 것으로 특히, 여러개의 등기구가 등기구 고정대에 설치되어 육중한 중량체를 가지는 조명탑이 전주를 따라 승강할 때 승강와이어가 절단되거나 승강장치의 구동부결함 등에 의해 조명탑이 급강하 하므로써 발생되는 위험을 방지하기 위한 가장 안전한 방법을 제공하는 안전브레이크 장치에 관한 것이다.The present invention relates to a safety brake device of an elevating light tower, and in particular, when a plurality of luminaires are installed on a luminaire fixture and a light tower having a heavy weight is elevated along an electric pole, the elevating wire is cut or the driving tower of the elevating device is damaged. It is a safety brake device that provides the safest way to prevent the danger caused by this dive.

종래에도 조명탑의 급강하 방지를 위한 비상브레이크 수단의 구조가 선등록 특허 제0495520호(공개번호 10-2005-0019704)에 게시되어 있다. 거기에는 전주양면에 스테인레스톱니 브레이크 라이닝이 브레이크 가이드 내부에 회전점을 중심으로 고정점이 상측으로 당겨진 상태로 고정되어 있다가 고정점을 당기고 있던 케이블의 장력이 상실되면 브레이크 가이드에 형성된 스프링의 탄발력으로 브레이크가 회전점을 중심으로 회전하면서 브레이크에 형성된 스테인레스톱니가 전주면에 접하면서 비상브레이크 기능을 수행하도록 된 것이므로 상기한 육중의 중량을 가지는 조명탑 이 순간적으로 급강하 하는 하중을 브레이크 가이드 내에 형성된 스프링의 탄발력 만으로 브레이크의 톱니면이 전주면에 밀착지지되는 제동력이 불가능한 문제점이 있었다.Conventionally, the structure of the emergency brake means for preventing the descent of the light tower has been published in the registered patent No. 0495520 (Publication No. 10-2005-0019704). There are stainless toothed brake linings on both sides of the electric pole, with the fixing point pulled upwards around the turning point inside the brake guide. When the tension of the cable pulling the fixing point is lost, the spring force formed in the brake guide As the brake rotates around the rotation point, the stainless teeth formed on the brake come into contact with the front surface to perform the emergency brake function. There was a problem that the braking force that the tooth surface of the brake is in close contact with the front circumference is not possible only by the power.

본 발명은 이러한 문제점을 해결하기 위하여 전주면을 따라 회전하는 조명탑 승강 안내로울러에 의하여 이동하도록 구성시킨 슬라이드판에 스톱퍼톱니가 래칫기어에 치합되어 슬라이드판이 밀려나지 않으면서 슬라이드판의 전주면 쪽에 축설된 조명탑안내로울러를 고정시켜 주어 전주의 4방 주면에 밀접되는 조명탑 안내로울러에 의하여 각 조명탑 안내로울러가 4방 전주면에 조여 붙여지는 큰 제동력으로 조명탑의 급강하를 안전하게 방지하여 조명탑의 급강하로 인한 위험을 방지토록 한다.In order to solve this problem, the stopper tooth is engaged with the ratchet gear on a slide plate configured to move by a light tower lifting guide roller rotating along the periphery of the slide plate. Fixing the light tower guide roller is a large braking force that each light tower guide roller is fastened to the four main pole surface by the light tower guide roller which is close to the main plane of the four poles of Jeonju to prevent the descent of the light tower. Prevent it.

본 발명은 상하 편차의 경사면을 가진 다각형(12각형) 전주(1)의 4방면을 따라 조명탑 승강 안내로울러(20)(20a)가 회전하면서 조명탑(6)이 급강하 하면 조명탑 승강 안내로울러(20)(20a)의 급격한 회전으로 캠(24)(24a)이 회동하면서 캠레버(26)(26a)와 로드레버연결판(28)(28a) 및 걸쇠(19)를 작동시켜 스톱퍼(16)의 하향걸림이빨(16a)이 레칫기어(15)에 치합되어 슬라이드판(13)(13a)의 이동을 저지하 므로써 조명탑 승강 안내로울러(20)(20a)의 회전중지로 조명탑 승강 안내로울러가 전주(1)의 4방면을 조여 붙여 조명탑(6)의 급강하를 방지시키므로 승강와이어(3)의 절단시 육중한 조명탑(6)의 급강하로 발생 할수 있는 위험을 종래의 안전브레이크에 비하여 가장 확실하게 방지 할수 있는 효과가 있다.According to the present invention, when the light tower 6 descends while the light tower lifting guide rollers 20 and 20a rotate along the four directions of the polygon (12-sided) pole 1 having an inclined plane of vertical deviation, the light tower lifting guide roller 20 is rotated. As the cams 24 and 24a rotate by the sudden rotation of 20a, the cam levers 26 and 26a, the rod lever connecting plates 28 and 28a and the latch 19 are operated to lower the stopper 16. As the engaging teeth 16a are engaged with the ratchet gear 15 to prevent the movement of the slide plates 13 and 13a, the light tower lifting guide roller is stopped by turning the light tower lifting guide rollers 20 and 20a. Tighten the four sides of) to prevent the descent of the light tower (6) to prevent the risk of descent of the heavy light tower (6) when cutting the lifting wire (3) can be most reliably prevented compared to the conventional safety brake It works.

이와같은 본 발명은 승강와이어 권취드럼 34의 회전으로 승강와이어(3)에 매달린 조명탑(6)이 승강할 때는 조명탑 승강 안내로울러(20)(20a)가 상,하 경사진 전주(1)면을 따라 안내되면서 조명탑(6)의 승강이 순조로우나 조명탑 승강와이어(3)가 절단이 되면 조명탑(1)이 순간적으로 급강하 함에 따라 조명탑 승강안내로울러(20)(20a)가 급회전 하면서 걸림쇠 회전판(23b)을 회전시키므로 걸림쇠(23) (23a)가 옻걸이기어(22)(22a)에 걸려 캠(24)(24a)을 회전시키므로 캠레버 하단 (26b)이 캠면을 따라 하강하면서 로드레버상단을 캠(24)(24a)쪽으로 밀고 로드레버연결판(28)(28a)을 함께 밀어 걸쇠(19)의 상향 걸림이빨(19a)을 스토퍼 상향걸림이빨(16b)에서 벗어나게 하면 스토퍼(16)의 하향이빨(16a)은 래칫기어(15)에 도 6에서와 같이 치합되어 슬라이드판(13)(13a)의 밀림이 없도록 고정하므로 조명탑 승강안내로울러(20)(20a)의 밀림이 없으므로 조명탑 승강안내로울러(20)(20a)는 전주(1) 주면에 압지되면서 조명탑(6)의 하강을 방지하므로 조명탑의 급하강으로 발생 될수 있는 위함을 방지 할수 있다.As described above, when the light tower 6 suspended from the lifting wire 3 is lifted by the rotation of the lifting wire winding drum 34, the light tower lifting guide rollers 20 and 20a are inclined up and down. When the light tower 6 is smoothly lifted and the light tower lifting wire 3 is cut while being guided along, the light tower 1 suddenly descends, and thus the light tower lifting guide roller 20, 20a rotates sharply, and the locking plate rotating plate 23b. Since the claws 23 and 23a are caught by the lacquered gears 22 and 22a, the cams 24 and 24a are rotated, so that the cam lever lower end 26b is lowered along the cam surface and the top of the rod lever is cam. 24) push the rod lever connecting plates 28 and 28a together to disengage the upward catching teeth 19a of the latch 19 from the stopper upward catching teeth 16b, and the downward teeth of the stopper 16 16a is engaged with the ratchet gear 15 as shown in FIG. 6 so that the slide plates 13 and 13a are not pushed. Therefore, since there is no jungle of the light tower lifting guide rollers 20 and 20a, the light tower lifting guide rollers 20 and 20a are prevented from descending the light tower 6 while being squeezed on the main surface of the electric pole 1 so that the light tower can be generated by the descent of the light tower. It can prevent the danger.
