Zusammenfassung: | The present invention relates to a constriction prevention device for a worktable of a high place working vehicle and, more specifically, relates to a constriction prevention device for a worktable of a high place working vehicle, capable of simultaneously inserting a constriction prevention bar supporting an upper detection bar and an auxiliary rail into four corners of the auxiliary rail in an upper part of a high place working vehicle, and being operated when contact of a separation operation stop switch is dropped to stop operation simultaneously with detecting a shock, so as to be safe. According to one preferred embodiment of the present invention, an upper detection bar fixing bolt and a compression prevention bar fixing bolt are loosened from an upper detection bar and a constriction prevention bar without changing the constriction prevention device, thereby attaching the auxiliary rail up to a top of an upper guide bar and easily removing the upper detection bar, so as to be easily operated with only the worktable; the separation operation stop switch is dropped when a shock is appt the upper detection bar or the auxiliary rail, thus being immediately stopped when receiving the shock to be safe; an upper detection bar protector formed with a synthetic resin material is formed in a top of the upper detection bar, thus being difficult to break even if an installed object installed in an upper part is touched; and a structure and installation of the constriction prevention device are simple, thus being difficult to fail and also providing high usability. According to the present invention, the constriction prevention device comprises a fixed plate and a moving plate.
본 발명은 고소작업차의 작업대용 협착방지장치에 관한 것으로, 더욱 상세하게는 고소작업차의 상부에 보조난간의 네 귀퉁이에 각 상부감지바와 보조난간을 지지하는 협착방지바를 동시에 꽂을 수 있도록 형성하고, 이탈작동멈춤스위치의 접촉이 떨어질 때 작동할 수 있도록 하여 충격을 감지함과 동시에 멈출 수 있어서 매우 안전한 고소작업차용 협착방지장치에 관한 것이다. 본 발명의 바람직한 실시예로 형성된 고소작업차의 작업대용 협착방지장치에 의하면 협착방지장치는 그대로 둔 상태에서 상부감지바와 협착방지바를 상부감지바고정볼트와 협착방지바고정볼트를 풀어서 보조난간은 상부가이드바의 바로 상단까지 붙일 수 있고, 상부감지바는 쉽게 제거할 수 있어서 작업대만으로 운용하기 쉽고, 상부감지바 또는 보조난간에 충격을 가하게 될 때 협착방지장치의 이탈작동멈춤스위치가 떨어지는 동작으로 작동하므로 충격을 받는 즉시 멈추게 되어 안전하며, 상부감지바의 상단에는 합성수지재로 형성되는 상부감지바보호구가 형성되므로 상부에 설치되어 있는 설치물에 닿더라도 잘 파손되지 않고, 협착방지장치의 구조가 간단하고 설치가 매우 간단하여 고장이 잘 나지 않을 뿐만 아니라 활용성이 매우 높은 등의 효과가 발생한다. |
