Description

Technical Field

[0001] This utility model relates to the technical field of tarpaulin machine lifting columns, specifically a tarpaulin machine lifting column with protective functions. Background Technology

[0002] Tarpaulin (or waterproof cloth) is a high-strength, flexible, and waterproof material. It is often used as canvas, polyester with polyurethane coating, or made of polyethylene plastic. Tarpaulins usually have sturdy grommets at the corners or edges for easy rope binding, hanging, or covering. When using tarpaulins, lifting columns are needed for height adjustment.

[0003] There is a movable lifting column (CN202020674086.7) that uses a drive mechanism inside the outer cylinder to raise and lower the lifting cylinder. The pre-embedded base does not require deep excavation for burial, and the base can be removed from the pre-embedded base. This makes the lifting column easier to install or retrieve and more convenient to maintain. However, it has shortcomings: the existing equipment has poor protection effect, poor installation adaptability, and cannot be flexibly combined and disassembled, making maintenance inconvenient. Therefore, a tarpaulin machine lifting column with protective function is needed to solve the above problems. Utility Model Content
