Description

Pneumatic lifting column

Technical Field

The utility model relates to a pneumatic lift post equipment technical field specifically is a pneumatic lift post.

Background

In life, a plurality of scenes can utilize the lifting columns, for example, the lifting columns are used as roadblocks, when the roadblocks need to be arranged, the lifting columns are lifted to serve as the roadblocks, and when the roadblocks do not need to be arranged, the lifting columns are lowered. However, the gravity of the lifting column causes a large load to the output structure of the power source, resulting in an unstable structure. In places such as parking lot entrances and exits and highway entrances and exits, control and switching of restriction and release of vehicles are often required. When the vehicle information is confirmed, the vehicle is required to be blocked; after the confirmation or charge is completed, the vehicle can pass quickly. The traditional approach is to use a vehicle blocking pendulum. The vehicle blocking swing rod is divided into a double swing rod, a single swing rod and the like. But the swing rod has poor anti-collision performance and does not have the capacity of preventing vehicles from forcibly passing. In addition, a hydraulic core and a motor core device of the lifting column are buried underground in the lifting column, and therefore the damage of possible electric leakage is caused due to flooding in rainy days and heavy rain storms. To this end, we propose a pneumatic lifting column.
