The flagpole frame is erected after being connected with the trivia strip, the bottom of the flagpole frame is arranged on the blocking frame plate, and the blocking frame plate can be made of plastic plates, rubber plates or wood plates. After the cast steel column tube seat is installed, 12 gilded monk nuts are arranged, and two monk nut placing shelf plates are arranged in the position of a central vertical line of a rectangular opening.

The bottom of the flagpole frame is seated on the shelf plate, and the top of the flagpole frame leans against the top flag post and inclines approximately 25 degrees.

After the Kevlar belt is flattened and bound, the other end of the Kevlar belt is inserted into a rectangular opening at a high altitude, the Kevlar belt is placed on the back of the transition wheel by hand, passes through the hollow flagpole pipe, is placed on a winding drum of the electric hoister in the basement to cut off the surplus and is wound on the winding drum for 1.5 circles, the left and right fixation is carried out, the flatness of the Kevlar belt is checked, and a lifting button is started to enable the Kevlar belt to be in a slightly tight state. The kevlar belt connection and installation is completed. The Kevlar belt passes through the rectangular opening from bottom to top, climbs over the transition wheel and rotates 360 degrees from top to bottom, and ideal rope or other hanging objects do not exist under the flag after the flag is raised.

Raising and lowering flag, and magnetic attraction condition

After a flag is sleeved on the flag sleeve rod, the flag is sent to the site, the flag sleeve rod can easily slide upwards into the first non-transparent round hole along the semicircular groove of the frame rod frame to compress the pagoda spring, and when the lower edge of the flag sleeve rod exceeds the second non-transparent round hole and is aligned with the round hole, the flag sleeve rod can be automatically sleeved into the second non-transparent round hole due to the elastic force and the dead weight of the pagoda spring. After the operation of the whole process is skilled, the whole process is finished in 3 seconds.

When a flag raising master presses a flag raising button on a fingerprint identification controller, an electric winch starts raising a flag, and the flag on a flagpole frame starts to slow down, but the raising speed is gradually increased because Kevlar belts on winding drums are overlapped and have larger and larger diameters, and the process of raising the flag from slow to fast is a condition that people cannot ask for the flag to rise stably.

When the flag raising button is pressed, the broadcast horn broadcasts the relevant performance music, and the specific time for raising the flag is preset by the asynchronous motor variable frequency controller.

At the moment when the flag rises, the Kevlar band rotates the flag pole frame by 90 degrees on the Kevlar band connecting shaft. And the flagpole frame is tightly attached to the flagpole pipe, so that the microswitch can be pressed, the electric winch stops the electric band-type brake to brake, and the process has microsecond time difference, so that the Kevlar belt is in a tight state. Due to the dead weight of the flagpole frame, the flagpole frame can be in a vertical hanging state due to the fact that the magnetic steel attracts the electrical soft iron to the maximum area, particularly the concave-convex inosculation surface, and the maximum horizontal magnetic attraction force of 15kg is inevitably produced after the magnetic steel inosculates.

The flag lowering is to reversely turn the triumph belt of the winch and is also controlled by the frequency conversion of the other asynchronous motor, and the controller adjusts the rotating speed of the motor, which is slower than the flag raising. Meanwhile, the flag lowering speed is gradually reduced from high speed, meanwhile, the magnetic attraction force and the weight of the flagpole frame greatly exceed 1:1 in the first item of the background technology, so that the flagpole frame can easily slide down to lower the flag by cutting a horseshoe-shaped magnet, the flagpole frame is hung by a Kevlar belt, an electric winch is controlled by a variable-frequency rotating speed controller, and a turbine speed reducer rotates reversely to have a certain damping effect, so that the situation of acceleration of free falling bodies is absolutely avoided, or the phenomenon that the lifting speed is increased more and more quickly occurs, the descending speed is very slow when the flagpole frame is fast to a steel column pipe, and finally the flagpole frame plate is touched, and the automatic stop can be realized by pressing a stop button.

The flag hand can easily catch the flag due to the slow flag falling speed, so that the flag cannot fall to the ground, and the flag conforms to relevant regulations.

Once the heavy load is met in severe weather, the M6 large flat-head screw on any side of the Kevlar belt connecting shaft can be detached and pulled out, the connecting shaft is separated from the Kevlar belt, the heavy load is installed again, and after the winch is started and ascended to the top, the heavy load can touch any one of the two microswitches to stop. The Kevlar tape exposed outside is recovered on the winding drum, and no shadow of the Kevlar tape can be seen outside the flagpole pipe.

Example two

This example uses magnetic attraction and kevlar belts instead of ropes, without the need for a flag pole stand. Refer to fig. 29 to 45.

For example: the width of the flag is 160 cm, and the length is 240 cm. The flag post pipe is composed of three sections, and the total height of the first type-II flag post, the second type-II flag post and the third type-II flag post is 21 m. The second type flag first flag post is 1.7 meters long and the outer diameter of the top of the post is 20 centimeters. The kevlar belt has a width of 32 mm and a thickness of 1.5mm, and the magnetic attraction is 4.5 kg.

The combination of the flag poles of the first and second types consists of five parts: a second type flagpole main body; secondly, inserting the second type of electrical soft iron lower insert; ③ Kevlar belt connecting screw; fourthly, pressing the flag board upwards; and fifthly, pressing down the flag screw.

The second type flagpole main body is a semicircle body with the diameter of 50 mm when viewed from the front, is a concave arc when viewed from the back, and has the taper of 0.35 degrees and the length of 1.6 meters. The convex arc of the flag pole is matched with the convex arc of the flag pole.

The back surface of the head of the main body of the second type flagpole is provided with a window, the width of the main body is 33, the depth of the main body is 19, the length of the main body is 15mm, the right side of the main body is provided with a rectangular opening, the diameter of the circular opening is 6mm, and the left side of the main body is provided with an M6 screw hole. The lower end of the main body is provided with two M8 screw holes which are used for connecting the lower insert of the second type of electrical soft iron by a countersunk head nut. Two M4 screw holes and two M4 screw holes are arranged above the main body at a distance of 26mm and are matched with an upper flag pressing plate to press an upper flag sleeve, and a screw hole with the depth of 30mm M10 is arranged in the center of the bottom of the lower insert of the second type of electrical soft iron to press a lower flag sleeve by a lower flag pressing screw.

After the second type of flagpole is assembled, the second type of flagpole is sleeved into a flag sleeve, the white flag sleeve with the length of 1 cm is pressed by an upper flag pressing plate and four M4 bolts, the white flag sleeve with the length of 4 cm is grown on the lower side, a lower flag pressing screw is firstly screwed into the majority of M10 bolt holes at the bottom of the second type of electrical soft iron lower insert, the white flag sleeve with the length of 4 cm is plugged into a gap, the bolts are screwed off again if the white flag sleeve is not plugged completely until the four sides are tightened, and then the white flag sleeve is screwed down.

(III) connecting Kevlar tapes: one end of the Kevlar belt is sewn into a circle with the diameter of 6mm, then the second type of Kevlar belt is sleeved into a hole with the diameter of 6mm at the right upper part of the synthesized second type of flagpole through a nut, then the Kevlar belt penetrates through the circle with the diameter of 6mm sewn by the Kevlar belt, and then the left M6mm screw hole is screwed tightly.

The other end of the Kevlar strip is sleeved into a 33 multiplied by 3 rectangular opening at the top of the first flag post of the second type of flags at high altitude, climbs into the Kevlar strip transition wheel, makes a 360-degree turn through the transition wheel, passes through the hollow flag post pipe, and winds onto a manual winding drum of the box-type base to be fixedly connected. A ratchet wheel is fixed on the side of the manual winding drum, a spring plate pawl is fixed on the wall of the box type base seat, the pawl is controlled by a 90-degree adjusting button of the pawl which rotates 90 degrees, the pawl is placed on the top of the teeth of the ratchet wheel, a winding drum shaft is sleeved with the pawl by a rocking handle, and the flag is lifted in a clockwise rotation mode.

The second type flag pole is combined with a dead weight of 5kg, the magnetic attraction force is set to be 4.5kg, the clockwise-rotated flag rises, and after the flag rises, the rocking handle needs to pass through 1-2 teeth of the ratchet wheel again to tighten the Kevlar belt. The pawl props against the ratchet reel to be in a braking state. The flagpole outside the first flag post of the second type flag is raised to the top of the flag post. The two kinds of electrical soft iron lower inserts combined below the second kind of flagpoles and the horseshoe-shaped magnet arranged on the inner side of the first flag post of the second kind of flags are in opposite positions, and the concave and convex surfaces can be matched to form a magnetic loop, so that 4.5kg of magnetic attraction force is generated. The flagpole will cling to the flag post.

After the flag is raised to the top of the pole, no rope or other objects are arranged below the flag pole. Because the Kevlar belt is tightly pulled, the magnet is attracted, namely the 8-level strong wind flagpole can not leave the flagpole pipe any more, and the flagpole can not descend half a point because the ratchet wheel and the winding drum are in a braking state.

When the flag is lowered, the 90-degree adjusting button of the pawl is rotated by 90 degrees to be positioned on the flag lowering mark, the pawl leaves the tooth top of the ratchet wheel, and the hand crank is reversely rotated to smoothly lower the flag.
