The invention discloses a manned protection device for a vehicle-mounted liftable working platform, and belongs to the technical field of engineering machinery and equipment. The manned protection device for the vehicle-mounted liftable working platform comprises a working platform and a hydraulic system used for controlling the working platform, wherein the working platform comprises a platform body; a fence, a self-locking door and a detection device are arranged on the platform body; the detection device is used for detecting whether operators exist in the working platform or not; the two ends of the self-locking door are connected with the fence through hinge pieces and lock catch devices separately; and the hydraulic system controls the working platform to move according to detectioninformation of the detection device. According to the invention, the self-locking door and the fence of the working platform jointly provide mechanical protection for operators, and automatic lockingcan be realized through the self-locking door design, so that the manned protection device for the vehicle-mounted liftable working platform is convenient and reliable to use; the hydraulic system isprovided with a manual stop valve and an electromagnetic valve, and capable of guaranteeing that ground workers cannot control the platform to move when people exist in the working platform, so that the falling injury of high-altitude operators due to work errors or misoperation is avoided.
本发明公开一种车载可升降工作平台载人保护装置,属于工程机械和设备技术领域。本发明的一种车载可升降工作平台载人保护装置,包括工作平台以及用于控制工作平台的液压系统,工作平台包括平台本体,平台本体上设置围挡、自锁门以及检测装置,检测装置用于检测工作平台内是否有操作人员,自锁门两端分别通过铰接件和锁扣装置与围挡连接,液压系统根据检测装置的检测信息控制工作平台移动。本发明中自锁门与工作平台围挡共同为操作人员提供机械防护,自锁门设计可实现自动闭锁,使用方便可靠,其中液压系统设置手动截止阀和电磁阀可以确保工作平台内部有人时,地面工作人员无法控制平台移动,避免发生因工作失误或者误操作,而发生高空作业人跌落伤害。
