Problems solved by technology

[0002] At present, the known lifting columns of lighting vehicles using pneumatic springs fix the lock and hook respectively on the first lifting cylinder and the last lifting cylinder and lock them to compress the pneumatic spring. When the hook and lock are opened, the lifting cylinder rises. , at this time, under the action of the pneumatic spring, several lifting cylinders rise rapidly. Because the top of the lifting cylinder is fixed with a lighting lamp, the weight is heavy, so the lighting lamp will swing left and right when it rises rapidly. In addition, when the surrounding environment is not clearly seen , Accidents may occur if you accidentally open the hook, which is very dangerous and extremely unsafe.

Abstract

A vertical lifting column for lighting vehicle is composed oftwo pneumatic springs, 5 lifting pipes, 3 internal sleeves, 3 pulley sets, 3 steel cables and a manual rocker fixed to the first lifting pipe for driving the lifting up or lowering down of said lifting column.

Description

Technical field: [0001] The invention relates to a stable lifting, safe and reliable lighting vehicle lifting column. Background technique: [0002] At present, the known lifting columns of lighting vehicles using pneumatic springs fix the lock and hook respectively on the first lifting cylinder and the last lifting cylinder and lock them to compress the pneumatic spring. When the hook and lock are opened, the lifting cylinder rises. , at this time, under the action of the pneumatic spring, several lifting cylinders rise rapidly. Because the top of the lifting cylinder is fixed with a lighting lamp, the weight is heavy, so the lighting lamp will swing left and right when it rises rapidly. In addition, when the surrounding environment is not clearly seen , Unintentionally opening the hook just may cause an accident, which is very dangerous and extremely unsafe. At the same time, if the lifting cylinder is to be lowered, the handle must be pulled hard to press down to compress...
