Description

고소작업대의 레일파이프 클램프 장치{Aerial work platforms rail pipe clamp system}Technical Field [0001] The present invention relates to a rail pipe clamp system for a work platform,

본 발명은 고소작업대의 레일파이프 클램프 장치에 관한 것으로, 보다 상세하게는 가드레일을 구성하는 레일파이프가 이탈되는 것을 방지할 수 있도록 하는 고소작업대의 레일파이프 클램프 장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a rail pipe clamping apparatus for a high work platform, and more particularly, to a rail pipe clamp apparatus for a high work bench which can prevent a rail pipe constituting a guard rail from being detached.

일반적으로 고층 건축물의 벽체에 외장작업을 하거나, 대형선박의 외장작업을 하기 위해서는 작업자가 작업할 수 있는 공간을 제공하고, 작업자가 추락하는 것을 방지할 수 있도록 하는 고소작업대를 설치하고 있다.Generally, a high work bench is installed to provide a space for workers to work on the walls of high-rise buildings or to externally work on large vessels and to prevent workers from falling down.

상기 고소작업대는 작업자가 작업을 할 수 있도록 발을 딛을 수 있는 공간을 제공하는 디딤판과 작업자가 균형을 잃고 추락하는 것을 방지할 수 있는 가드레일 장치로 구성되는데, 종래의 가드레일 장치는 클램프에 레일파이프를 고정할 수 있도록 적재할 경우, 레일파이프가 이탈하는 것을 방지할 수 있는 수단이 구비되어 있지 않아 레일파이프가 추락하지 않도록 매우 천천히 조심스럽게 설치할 수 밖에 없어 가드레일 장치를 설치하는데 많은 시간이 소요되어 생산성을 떨어뜨리게 되는 문제점이 있었다.The elevating table is composed of a tread plate providing a space for the foot to allow the operator to work and a guard rail apparatus capable of preventing the operator from losing balance and falling. It is very slow and careful to install the rail pipe so that the rail pipe does not fall down because there is no means to prevent the rail pipe from coming off when the pipe is fixed so that it can be fixed. Thereby deteriorating the productivity.

또한, 종래의 가드레일 장치는 클램프 장치와 레일파이프 사이의 조립공차에 의한 유격에 의해 레일파이프가 클램프에서 이탈하게 되는 것을 방지할 수 있도록 하는 수단이 구비되어 있지 않아 이탈된 레일파이프와 함께 작업자가 추락하게 될 수 있는 위험성을 갖는 문제점이 있었다.In addition, in the conventional guardrail device, there is no means for preventing the rail pipe from being released from the clamp due to the clearance due to the assembly tolerance between the clamp device and the rail pipe, There has been a problem that there is a risk of falling.

레일파이프와 잘 밀착될 수 있도록 상기 덮개의 하부면에는 레일파이프 상부의 외면 형상과 같은 직경의 호 형상을 갖는 밀착홈을 형성하여,A contact groove having a circular arc shape having the same diameter as the outer shape of the upper portion of the rail pipe is formed on the lower surface of the lid so as to be closely adhered to the rail pipe,

잠금볼트와 결합되는 핸들의 하부면이 덮개에 형성된 잠금볼트수용홈의 상부면을 가압하여 적재된 레일파이프를 동시에 고정할 수 있도록 구성할 수 있다.The lower surface of the handle coupled with the locking bolt may be configured to press the upper surface of the locking bolt receiving groove formed in the lid to fix the loaded rail pipe at the same time.

또한, 본 발명은 적재홈의 내부에서 레일파이프가 이탈하는 것을 방지할 수 있도록 레일파이프의 양측 끝단을 가압하여 적재홈의 폭보다 큰 폭을 갖도록 형성된 확개부를 더 구비할 수 있다.Further, the present invention may further include a widening portion formed to press both ends of the rail pipe so as to have a width larger than the width of the loading groove so as to prevent the rail pipe from being detached from the inside of the loading groove.

본 발명은 레일파이프의 양쪽 끝단을 가압하여 직경보다 넓은 폭을 갖는 확개부를 형성함으로써, 클램프의 몸체 측면에 형성된 적재홈의 내부로 수용된 레일파이프에 유동이 발생하더라도 확개부가 몸체의 측면과 접촉하여 이탈되는 것을 방지할 수 있게 되어 레일파이프의 추락으로 인한 안전사고의 발생을 미연에 방지할 수 있는 효과가 있고, 이탈의 염려없이 빠르게 레일파이프를 설치하는 것이 가능하므로 가드레일 장치의 설치와 분해에 소요되는 시간을 크게 단축시키는 효과가 있다.The present invention is characterized in that both ends of a rail pipe are pressed to form a widening portion having a width larger than the diameter, so that even if a flow occurs in a rail pipe accommodated in a loading groove formed in a side surface of a body of the clamp, It is possible to prevent the occurrence of a safety accident due to the fall of the rail pipe, and it is possible to quickly install the rail pipe without worrying about escape. Therefore, it is necessary to install and disassemble the guard rail device It is possible to greatly reduce the time required for the operation.
