The invention discloses a platform safety protection system of a large-platform overhead working truck. The system comprises an operation platform formed by a supporting plane, a front coaming and twoside coamings. Two rotary telescopic devices and two telescopic and self-locking sliding plates are symmetrically arranged at a rear end of the operation platform. Two soft shaft plug pins are symmetrically arranged at the rear end of the operation platform 1 and are used for making the two rotary telescopic devices be locked. The protection system is compact in structure, a rotary plate, a telescopic plate, a corresponding oil cylinder and a pipeline are hidden and arranged inside, a risk of pipeline damage is reduced, and meanwhile a whole truck structure is simpler and more attractive. Ina working process, the rotary plate only needs to be operated once, a lamp pole can be placed into the operation platform, and operation efficiency is improved.

    本发明公开了一种大平台高空作业车的平台安全防护系统,包括由支撑平面、前围板以及两个侧围板组成的作业平台,作业平台的后端分别对称设置有两个旋转伸缩装置和两个能够伸缩和自锁的滑板,作业平台1后端还对称设置有两个软轴插销用于控制两个旋转伸缩装置锁死,本防护系统结构紧凑,实现了旋转板、伸缩板及对应油缸、管路的隐藏内置,降低了管路损坏的风险,同时又使整车结构更简洁美观;在工作过程中,旋转板只需要进行一次操作即可将灯杆放入操作平台,提高了作业效率。
