The invention discloses a lifting type equipment locking device which comprises a plurality of layers of lifting units, and each layer of lifting unit is composed of an inner frame, an outer frame, an upper end locking device, a bottom pressing device and a lifting oil cylinder. The outer frame of the upper-layer lifting unit serves as the inner frame of the lower-layer lifting unit; the lifting oil cylinder is hinged between the inner frame and the outer frame, the inner frame moves up and down relative to the outer frame through the lifting oil cylinder, the upper end locking device is connected with the outer frame, and the bottom pressing device is connected with the inner frame. A first cushion block with a bolt hole is fixed on the inner frame; a second cushion block is fixed to the inner surface of the outer frame, the lifting oil cylinder stops acting, the small-diameter section of a plug pin of the upper end locking device is inserted into a plug pin hole of the first cushion block, the end face of the large-diameter section abuts against the surface of the first cushion block, and meanwhile a bottom pressing device of the inner frame acts to be extruded to the surface of the second cushion block. And the stability and safety of high-altitude operation are ensured.
本发明公开了一种升降式设备锁紧装置,包括多层升降单元,每层升降单元由内框架、外框架、上端锁紧装置、底部压紧装置、举升油缸组成;上层升降单元的外框架作为下层升降单元的内框架;举升油缸铰接在内框架和外框架之间内框架借助举升油缸相对于外框架上下移动,上端锁紧装置与外框架连接,底部压紧装置与内框架连接;内框架上固定有带插销孔的第一垫块;外框架内表面固定有第二垫块,举升油缸停止动作,上端锁紧装置插销小径段插入第一垫块的插销孔中,大径段端面抵靠在第一垫块表面,同时内框架底部压紧装置动作,挤压到第二垫块表面。保证了高空作业的稳定、安全。
