The invention relates to a high-safety lifting device for communication cable maintenance. The high-safety lifting device comprises a vehicle body, a lifting mechanism and a protection mechanism, the lifting mechanism is arranged on a vehicle body, and the protection mechanism is arranged on the lifting mechanism. According to the high-safety lifting device for communication cable maintenance, the lifting and lowering of a bottom plate is realized through the lifting mechanism, movement of the lifting mechanism is limited through the protection mechanism, so that sudden descending of the bottom plate caused by sudden breaking of a pull rope is avoided, maintenance personnel on the bottom plate are protected, compared with an existing lifting mechanism, the mechanism can be collected through ascending and descending of a movable rod and a pull rod, space is saved, compared with an existing protection mechanism, double limiting is conducted on the bottom plate through a fixing assembly and a clamping assembly, so that a better fixing and limiting effect is achieved on the bottom plate, meanwhile, sudden descending of the bottom plate caused when the lifting assembly breaks down is avoided through the clamping assembly, and maintenance personnel on the bottom plate are protected.
本发明涉及一种安全性高的用于通信电缆维修的提升装置,包括车体、升降机构和保护机构,所述升降机构设置在车体上,所述保护机构设置在升降机构上,该安全性高的用于通信电缆维修的提升装置,通过升降机构实现底板的升降,通过保护机构对升降机构的移动进行限位,从而避免拉绳突然断开时,造成底板的突然下降,对底板上的维修人员进行保护,与现有的升降机构相比,该机构可通过对移动杆和拉杆的升降,实现收纳,节省了空间,与现有的保护机构相比,该机构通过固定组件和卡紧组件对底板进行双重限位,从而对底板实现更好的固定限位效果,同时通过卡紧组件避免升降组件发生故障时而造成底板的突然下降,对底板上的维修人员进行保护。
