Description

The national flag lifting gear

A kind of national flag lifting gear particularly has and national flag is waved and national flag lifting gear regularly.

Existing national flag lifting gear be manual and electronic all do not have and with the corresponding time set function of national anthem, under no setting-up time and national flag wave the condition of device, make flagraising ceremony cannot not seem strong heavy, flag does not wave and regrets especially when particularly calm, has influenced the solemnity and the sense of pride of raising national flag.Have only patent documentation patent announcement 2087656U through the Searches of Patent Literature, the simple and easy flagraising flagpole of application number 91201887.9 is only put halyard in bar, and elevator chamber locks, and the top top sheave is rotatable to drift flag with the wind, avoids halyard to lose.

The purpose of this utility model is on the basis of original flagpole, install the device that waves (blast fan) that makes flag additional, cooperate the length of national anthem that the electric installation of rise time is set, and when calm, utilize blast fan blowing to make flag bats of wafing, make flagraising ceremony more solemn and take pride in.

Superiority of the present utility model is the flagpole applicable to all top dress pulleys, can cooperate national anthem to make flag be raised to the top by the program setting time in good time, and the mode of utilizing air blast that flag is waved is brought special effect to ceremony, and the air blast mouthpiece is provided with about flag, also can avoid flag to tangle.Also can be made into large, medium and small three kinds in addition, and adopt dry cell, make meeting more grand for the hand-held flag that waves of athletic meeting personnel.

The utility model is to realize like this, on the pulley of original flagpole, adorn halyard, the rear flank face dress blowing device of flag, this blowing device system is by two fans establishing the flagpole rear side of motor band, blowing mouth is aimed at the both sides of flag, power supply is drawn by the electric wire axle of elevator chamber, and elevator chamber is provided with the coaxial power line wheel of motor drives the halyard wheel, by the control panel button control ascending, descending and the blowing of elevator chamber.The lifting flag makes driven pulley drive halyard wheel lifting flag by the motor drives worm and gear, also drives the power line wheel simultaneously and rotates, and the folding and unfolding power line for speed and the time of adjusting the ascending, descending flag is provided with the control road, only need touch the button and can handle, and also can control blowing.

Now contrasting accompanying drawing is described as follows with regard to embodiment:

Present embodiment (Fig. 1) is made up of blowing part 2, lifting part 6 (comprising control, reception and actuating unit) and flagpole 5, and blowing part 2 (Fig. 2, Fig. 3, Fig. 4) 17,43 is a fan, and 16 is blowing mouth, 9 are the stepless time adjustment motor, and 7 are blowing part body, and 15 is turncap, 19,20 is hex nut and packing ring, 11 are the glue envelope, and 10 is that bucker, 13 is flexible dog screw and spring, and 38 is bearing, 39 is filter mantle, 40 is screw, and 41 is middle bearing bracket, and 42 is vent window.Transfer blowing mouth 16 angles during by dress as required.Lifting part 6 (Fig. 5, Fig. 6) comprises 14 halyards wheel, 12 hinges, 21 driven shafts, 22 axle keys, 23 worm screws, 24 worm gears, 25 carriages, 26,27 is bolt and fastening card, 28 power lines wheel, 29,45,46 bearings, 30 operated keys, 31 chamber doors, 32 door locks, 33,36 waterproof aprons, 34 panels, 35 water-stop sheets, 37 stepless time adjustment motor.Blowing part: turncap 15 opened to take out hold flagpole 18 and penetrate in the flag cover, be pressed into groove again, screw turncap 15, the part of will drying body 7 transfers near the elevator chamber 6, with air blast part mouthpiece be loaded on the flag back lower place about two fans of two sides by a motor drives, mix up required time (debugging of not starting shooting) earlier according to the length that rises to masthead.Connect power supply then, can rise together with blowing part, when falling flag, the part of will drying again rises in the air to be deposited, lifting gear 6 is that casing is contained on the flagpole 5 with fastening card and screw (26,27), halyard 3 is passed halyard guide wheel 14, adorn the halyard hasp, transfer to the pulley rear of flagpole 5, make the 14 reliable transmissions of halyard guide wheel, connect power supply, transfer the time on the control panel 34, speed is seen the demonstration time from the number screen, button 30 during flagraising, lower flag then by back bond 30, close the chamber door lock also, the action situation; Switch power supply rotates motor 37, make halyard guide wheel 14 rotations on worm gear 24 coaxial 21 drive halyard 3 motions by worm gear 15, worm screw 23 (becoming 90 °) transmission, reach the lifting purpose, worm gear 24 drives coaxial power line wheel 28 rotations, to finish the process of receiving power line of sending.

The work of control circuit divides automatically and manual two parts, when power turn-on 47, get final product automatic and manual work, automatically part 51-2 connects contactor 57-1 and 53 through master switch 49 again to auxiliary reclay 50-1 to auxiliary reclay, connect power supply through limit switch 54, at this moment contactor 53 adhesive motor 37 operations, here contactor 53 and 57 is used for both forward and reverse directions control, manually part is through press button 52, contactor 57-1 by switch 49, contactor 53, limit switch 54 is to power supply, upper-lower position is finished by limit switch 54 and 58, and the air blast part is the same.With 34 control times of remote control panel and velocity transformation, when middle relay 50 and 51 actions, control motor forward and backward, 37 operations of relay 63 action control motor are with the control of realization time and speed.

The utility model has realized that national flag waves in the same old way when calm, the setting of the time of hoisting a flag makes the more serious order of flagraising ceremony, inspires people to have ardent love for the motherland more.
