Technical Field
[0001] The utility model relates to the technical field of guardrails, in particular to a lifting guardrail. Background Art
[0002] The lifting guardrail is mainly used for traffic safety management and control. It can be quickly raised or lowered to define the boundaries between different lanes to prevent vehicles from illegally crossing or driving across the line. In addition, the lifting guardrail is also widely used in various fields, including traffic management, safety protection and property management. For example, in traffic management, the lifting guardrail can be used to control the entry of vehicles into specific areas, such as highway entrances and exits, toll stations, etc., to reduce violations and road congestion. In terms of safety protection, the lifting guardrail can be used to protect important facilities such as airports, subway stations, large-scale event venues, etc., to prevent malicious damage and illegal intrusion. In property management, the lifting guardrail can be used for entrance and exit management of residential areas, commercial centers and other places to improve safety and management efficiency. In general, the lifting guardrail is an important traffic safety equipment that controls the entry and exit of vehicles in specific areas through the lifting operation of the electric motor.
[0003] After searching, the patent number "CN108867472A" mentioned in the text that "the present invention discloses a lifting guardrail, including: a base, a guardrail column, a guide rail, a cross bar, a vertical bar, a telescopic rod, a rotating shaft, a turntable, and a circular hole. A guide rail is vertically fixed on the end face of each guardrail column facing the center of the base. The cross bar is slidably connected to the guide rails on both sides through a groove. There are two cross bars in total. The vertical bar is evenly and vertically fixed between the two cross bars. The telescopic rod is fixed to the left and right sides of the lower end face of the lower cross bar. The lower end of the telescopic rod is fixed to the upper end face of the base.
