Cascade type hard telescopic fence
The invention discloses a cascade type hard telescopic pole. The cascade type hard telescopic pole is provided with a plurality of unit fences, wherein each unit fence comprises a left stand column, aright stand column and a shrinkage fence for connecting the left stand column to the right stand column; rotary shafts are arranged on the bottom of the left stand column and the bottom of the rightstand column, and the bottoms of left and right stand columns are provided with locking bolts for locking the rotary shafts; the lower ends of the rotary shafts are connected to a movable base; a plurality of groups of horizontal fixed columns which are arranged at equal height are arranged on the left and right stand columns; lock arms capable of rotating around the horizontal fixed columns are hung on the horizontal fixed columns; and two lock holes which are reversely formed are arranged on the lock arms. The cascade type hard telescopic fence is simple in structure, is delicate in design,realizes seamless isolation protection on electrified operation equipment and interruption maintenance equipment, realizes storage and locking of each unit fence as well as interconnection of multiplestages of unit fences, and greatly facilitates once transportation of each unit fence on the site.
本发明公开了一种级联式硬质伸缩围栏，具有若干个单元围栏，每个单元围栏包括有左立柱、右立柱和连接左、右立柱的收缩栅栏，在左、右立柱的底部均装有转轴，并配置有用于锁紧转轴的锁紧螺栓；转轴的下端连接移动底座；在左、右立柱上设有若干组等高布置的水平固定柱，在水平固定柱上挂接有可绕其旋转的锁臂，在锁臂上设有两个反向布置的锁口；本发明结构简单、设计巧妙，实现了对带电运行设备与停电检修设备的无漏洞隔离防护，并实现了每个单元围栏自身的收纳锁紧及多级单元围栏之间的互连，大大方便了现场对各个单元围栏的一次性搬运。
