Flag hoisting and lowering mechanism of flag pole

Abstract

The invention discloses a flag hoisting and lowering mechanism of a flag pole, which comprises a driving mechanism, a transmission mechanism, a flag hoisting and lowering in-place positioning mechanism, a flag hanging component and a crown component, wherein the driving mechanism is arranged on the lower part of the flag pole; the transmission mechanism is connected with the driving mechanism, comprises a driving wheel component, a driven wheel and a chain bead type steel wire rope movably connected with the driving wheel component and the driven wheel, and is connected with the flag hanging component through a flag hoisting and lowering steel wire rope fixedly connected with the chain bead type steel wire; the flag hoisting and lowering in-place positioning mechanism is arranged on the upper part of the driving wheel component; the flag hanging component is arranged on the outer side of the top part of the flag pole; and the crown component is arranged on the top part of the flag pole and makes the flag hanging component rotate in a range of 360 DEG C. The driving mechanism drives the chain bead type steel wire rope to move up and down, and the chain bead type steel wire rope drives the flag hoisting and lowering steel wire to move upwards or downwards to ensure that the flag hanging component moves downwards or upwards to realize flag hoisting and lowering; and when a flag is hoisted and lowered in place, the position of the flag is limited by a limiting mechanism. The flag hoisting and lowering mechanism has the characteristics that the running is smooth and reliable, transmission and flag hoisting and lowering ropes have no distortion and twisting, the flag can rotate automatically along with the wind direction, the flag can be hoisted manually when an abnormal condition appears, and the like.

Description

【Technical field】 [0001] The invention relates to a flagpole, in particular to a flagpole raising and lowering mechanism which can automatically raise and lower flags in an electric manner and manually raise and lower the flag in the case of power failure. 【Background technique】 [0002] As we all know, a flag-raising ceremony will be held when important events or ceremonies are held. This ceremony is to raise the flag, such as the national flag and the meeting flag, from the lower part to the top of the flagpole within a certain period of time on the flagpole. The traditional flag-raising process is done manually. The upper end of the traditional flagpole is equipped with a pulley, a rope is passed around the pulley, the flag is tied to one end of the rope, and the flag hoist continuously pulls the other end of the rope to raise the flag. Obviously, this way of raising the flag is a backward way because it is done manually, and the flag-raiser must undergo long-term traini...

Problems solved by technology

Obviously, this flag-raising method is a backward method because it is done manually, and the flag-raiser must undergo long-term training before he can master the rhythm and time of flag-raising.

For this reason, people have developed an electric flag-raising device. The transmission mechanism of the existing electric flag-raising device adopts a drum coil or a chain drive. When this type of device is used, abnormal conditions such as twisted or twisted coils often occur, resulting in delays in the flag-raising process. or interrupt

In addition, the flag of the traditional electric flag raising device is fixed on one side of the flagpole when it is raised to the top of the flagpole, and its position remains unchanged regardless of the wind direction, which will affect the effect of the flag flying

In addition, the traditional electric flag raising device does not consider emergency measures such as power failure, so that in the event of a power failure, the mechanism will be locked due to the motor stopping and the flag cannot be raised manually.
