Innovative flagpole lifting device

Abstract

The invention discloses an innovative flagpole lifting device. The innovative flagpole lifting device comprises a base, a flag column tube and a basement winch reel, wherein the flag column tube is arranged on the base, and the basement winch reel is arranged at the bottom of the base; the flag column tube is provided with a rectangular opening in the top, a Kevlar belt transition wheel is installed on the lower edge of the inner side of the rectangular opening, a Kevlar belt is connected with a flagpole frame outside the flag column tube, and the other end of the Kevlar belt penetrates through the rectangular opening, climbs over the Kevlar belt transition wheel, rotates by 360 degrees, passes through the hollow flag column tube and is wound around the reel. Electric soft iron is arrangedat the lower end of the flagpole frame, a horse shoe magnet is arranged on the inner wall of the top segment of the flag column tube, in the center line of the rectangular opening and at the positionof equal distance to the electric soft iron of the flagpole frame, and after a flag on the flagpole frame is lifted to the top of the flag column tube, the electric soft iron and the horse shoe magnet are right located at the same position to generate strong-magnetism attraction force for fixing. With the innovative flagpole lifting device, the three problems can be solved that after the flag islifted to the top, a rope, a column winding ring, hanging weight objects on the lower portion of a flagpole and others are arranged outside the flag column tube; when the flag encounters strong wind or due to the fact that compressed air is jetted and blown, the flag leaves from the column tube; the pull rope of the flag leaves from the top of the column tube under influencing of all kinds of factors. With the innovative flagpole lifting device, the solemnity and liberality of a flag-raising ceremony are kept, and the effects of attractiveness and vitality are realized.

Description

technical field [0001] The present invention generally relates to a lifting device, and more specifically, relates to a flag raising device for a large flag. Background technique [0002] By observing the state of use of the existing flag, there are three obvious problems after the flag is raised: (1) After the flag is raised to the top of the column tube, there are ropes or other hanging objects outside the column, the flag flutters in the wind, and Under the action of the wind, the rope flapped the flag irregularly, and then made a noise, drooping without wind, showing no spirit. (2) The flag is raised less than 20 cm below the top of the column; (3) When the 4th wind blows, either the top of the flagpole is away from the flag column tube, or the tail of the flagpole is away from the column tube, forming a gap, and the gap varies with the wind speed. The ropes are exposed to the sun and rain, which not only affects the service life of the ropes but also seriously affects ...

Problems solved by technology

[0002] By observing the state of use of the existing flag, there are three obvious problems after the flag is raised: (1) After the flag is raised to the top of the column tube, there are ropes or other hanging objects outside the column, the flag flutters in the wind, and Under the action of the wind, the rope flapped the flag irregularly, and then made a noise. There was no wind, and it seemed to be listless.

(2) The flag is raised less than 20 cm below the top of the column; (3) When the 4th wind blows, either the top of the flagpole is away from the flag column tube, or the tail of the flagpole is away from the column tube, forming a gap, and the gap varies with the wind speed. The rope is exposed to the sun and rain, which not only affects the service life of the rope, but also seriously affects the solemnity and beauty of important flags
