Description

Technical Field

[0001] The utility model belongs to the technical field of lifting road piles, and in particular relates to a lifting column with a square pre-buried structure. Background Art

[0002] Lifting bollards are road barriers, mainly used for urban traffic road management. They are commonly placed on gate roads. When a row of lifting bollards rises, it forms an obstacle on the road and vehicles cannot pass through. When a row of lifting bollards falls, the road surface returns to a flat state and vehicles can pass through. The main advantage of lifting bollards is that when the road piles in the lifting bollards fall, they can be hidden underground, so that there are no obstacles on the road surface, which is more beautiful.

[0003] At present, there are various types of lifting columns, such as hydraulic drive, pneumatic drive, and electric drive. The shell at the bottom of the lifting column is buried underground. Various power mechanisms such as hydraulic movement, pneumatic cylinder, electric lifting push rod, etc. are arranged in the shell. Guide rods that guide the pile body are arranged in the shell. The internal structure of the shell is relatively complex, the production cost is high, and the structure is not compact enough and is relatively bulky. Utility Model Content
