The invention belongs to the field of protective guardrail application equipment, and particularly relates to an automatic telescopic guardrail convenient to store, which comprises a guardrail, a movable pulley, a steel wire rope, a counterweight, an upper stop block, a lower stop block, a guide rod and a guide sleeve, the guide sleeve is fixed on a lifting platform, the guide rod is fixed on the guardrail, the movable pulley is fixed below the lifting platform, the steel wire rope penetrates through the movable pulley, and the counterweight is fixed on the guide sleeve. One end of the steel wire rope is fixed below the guardrail, the other end of the steel wire rope is connected with the balance weight, the weight of the balance weight is larger than that of the guardrail, the upper check block is fixed to the side of the lifting platform, and the lower check block is fixed below the lifting platform. The guardrail descends depending on the weight of the guardrail. Stretching and retracting of the guardrail are achieved by means of gravity instead of electric driving, energy is saved, space above the lifting platform is not occupied when the guardrail retracts, and vehicles can conveniently pass through the platform.
本发明属于防护护栏应用设备领域,尤其涉及一种收纳便捷的自动伸缩护栏,包括护栏、动滑轮、钢丝绳、配重、上挡块、下挡块、导杆、导套,所述导套固定在升降平台上,导杆固定在护栏上,动滑轮固定在升降平台的下方,钢丝绳穿过动滑轮,一端固定在护栏的下方,一端与配重连接,配重的重量大于护栏的重量,上挡块固定在升降平台的侧方,下挡块固定在升降平台的下面,当升降平台上升到一定高度时,配重通过钢丝绳拉动护栏上升,当升降平台下降到一定高度时,护栏依靠自身的重量下降。本发明依靠重力实现护栏的伸缩,不依靠电气等方式驱动,节约能源,护栏缩回时不占升降平台上方空间,方便车辆在平台上通行。
