Description

완강기{A drop controller of emergency-escape-rope}Downhill {A drop controller of emergency-escape-rope}

본 발명은 완강기에 관한 것으로, 더욱 상세하게는 로우프권취휠에 감속휠이 아이들기어를 매개로 내접 치합되어서 역 회전되도록 동일 축상에 축지되게 구성하여서 낙하하중에 의한 변형손상을 방지할 수 있도록 하며, 로우프권취휠에 브레이크드럼을 일체로 형성하여서 구성을 단순함과 더불어 감속효과를 극대화할 수 있도록 함을 목적으로 한 것이다.The present invention relates to a stiffener, and more particularly, the reduction wheel is internally engaged to the rope winding wheel via an idle gear to be axially configured to be reversely rotated so as to prevent deformation damage caused by falling load. The purpose is to form a brake drum integrally with the rope winding wheel to simplify the configuration and maximize the deceleration effect.

일반적으로, 완강기는 아파트나 학교등과 같이 다층으로 이루어진 건축물에 있어서 화재등과 같은 비상사태 발생시 로우프를 이용하여 탈출할 때 사용하는 것으로서, 하강속도를 감속시켜서 탈출시 급강하로 인한 사고를 방지할 수 있도록 하는 것이다.In general, slumber is used to escape by using rope in case of emergencies such as fire in multi-layered buildings such as apartments or schools, etc. To ensure that

상기한 바와 같은 종래의 완강기는 로우프(300)가 권취되며 몸체(240)에 축지된 로우프권취휠(210)과, 상기 로우프권취휠(210)의 상측 몸체에 구비된 브레이크드럼(230)과, 상기 로우프권취휠(210)과 치합되며 상기 브레이크드럼(230)에 감속부측이 수납되게 결합되는 감속휠(220)과, 구성품을 밀폐할 수 있게 몸체의 전면으로 결합되는 하우징(250)으로 구성된 것으로, 상기 감속부는 호형바로 이루어진 다수의 원심브레이크(221)가 안착될 수 있게 브레이크 수납부가 형성되게 구성되어 있는 것이다.Conventional steel bar as described above is the rope winding wheel 210 is wound around the rope 300 and the body 240, the brake drum 230 provided on the upper body of the rope winding wheel 210, It consists of a reduction wheel 220 that is engaged with the rope winding wheel 210 and coupled to the brake drum 230 so that the reduction unit side is received, and a housing 250 coupled to the front of the body to seal the components. The deceleration part is configured such that a brake accommodating part is formed so that a plurality of centrifugal brakes 221 made of an arc bar can be seated.

이상과 같은 종래의 완강기는 비상탈출과정에 있어 로우프권취휠(210)이 로우프(300)에 의하여 회동되고 상기 로우프(300)에 의하여 회동되는 로우프권취휠(210)과 치합된 감속휠(220)이 회동되며, 상기 감속휠(220)이 회동되는 과정에 있어 감속부의 원심브레이크(221)가 브레이크수납부에서 원심 이탈되어서 브레이크드럼(230)과 마찰접촉되는 것이다.The conventional steel bar as described above, the deceleration wheel 220 engaged with the rope winding wheel 210 is rotated by the rope 300 and rotated by the rope 300 in the emergency escape process. Is rotated, the centrifugal brake 221 of the deceleration part in the process of the rotation of the deceleration wheel 220 is centrifugally separated from the brake housing portion is in friction contact with the brake drum (230).

이와 같이 원심브레이크(221)와 브레이크드럼(230)의 마찰접촉을 하게되면 감속휠의 회전이 제한되고 이로 인하여 로우프권취휠(210)의 회동이 제한되므로 로우프의 하강속도가 일정속도 범위로 제한되게 되는 것이다.As such, when the friction contact between the centrifugal brake 221 and the brake drum 230 is limited, the rotation of the reduction wheel is limited, and thus the rotation of the rope winding wheel 210 is limited, so that the descending speed of the rope is limited to a certain speed range. Will be.

그러나, 상기한 바와 같은 종래의 완강기는 로우프권취휠(210)과 감속휠(220)이 몸체(240)에 일측만이 고정된 각각의 축에 축지되게 구성되어 있어 하강 하중에 의하여 로우프권취휠(210)의 축이 변형되거나 몸체(240)가 변형시 감속휠(220)과의 치합상태가 해제되어 하강속도의 제어가 이루어지지 않게 되는 등의 문제점이 있었다.However, the conventional stiffener as described above is configured such that the rope winding wheel 210 and the deceleration wheel 220 are axially supported on each shaft having only one side fixed to the body 240 so that the rope winding wheel ( When the shaft of the 210 is deformed or the body 240 is deformed, there is a problem such that the engagement state with the reduction wheel 220 is released and the control of the descending speed is not made.

그리고, 상기한 바와 같이 로우프권휠(210)과 감속휠(220)이 별도의 축에 의하여 설치되어 있어 전체적인 몸체(240)의 크기가 비대하게 형성되는 문제점이 있어다.As described above, the rope winding wheel 210 and the reduction wheel 220 are installed by separate shafts, so that the size of the entire body 240 is enlarged.

또한, 감속휠(220)에 의한 감속이 고정된 브레이크드럼(230)과 마찰접촉되는 원심브레이크(221)에 의하여만 이루어지게 구성되어 있어 감속효과가 미약하고 설정치의 감속효과를 갖기 위하여는 브레이크드럼(230)과 마찰접촉되는 원심브레이크(221)의 면적을 최대화 하여야 하므로 감속휠(220)의 크기가 비대해지는 등의 문제점이 있었다.In addition, since the deceleration by the deceleration wheel 220 is made only by the centrifugal brake 221 in friction contact with the fixed brake drum 230, the deceleration effect is weak and in order to have a deceleration effect of the set value, the brake drum Since the area of the centrifugal brake 221 in friction contact with 230 should be maximized, there was a problem such that the size of the reduction wheel 220 is enlarged.

이에, 본 발명은 상술한 문제점을 해결하기 위하여 창출한 것으로, 로우프권취휠에 감속휠이 아이들기어를 매개로 내접 치합되어서 역회전되도록 동일 축상에 축지되게 구성하며, 로우프권취휠에 브레이크드럼을 일체로 형성한 것이다.Accordingly, the present invention has been made to solve the above-mentioned problems, the reduction wheel is internally engaged to the rope winding wheel through the idle gear is configured to be axially rotated to reverse rotation, integrated brake drum on the rope winding wheel It is formed by.
