Detailed Description
The automatic pulling-off slogan sheath provided by the invention is explained below with reference to the accompanying drawings.
Fig. 1 is a schematic structural diagram of an automatic pulling-off tagline sheath provided by the present invention, and as shown in fig. 1, the present invention provides an automatic pulling-off tagline sheath, including: the jacket comprises a jacket body 1, a jacket counterweight 2, a tagline counterweight 3 and an upper end friction block 4.
The jacket body 1 is of a strip-shaped structure, a plurality of openings are formed in the lower end of the jacket body, canvas or jean is used as a material, and segmented zippers are arranged on two sides of the jacket body;
the sheath counterweight 2 is a cylinder poured by cement, is embedded with a hook and exposes the upper part of the hook;
the slogan counterweight 3 is a cylinder cast by metal, and the material can be selected from steel or tungsten alloy and other high-density metals according to the task conditions;
the upper end friction block 4 is made of rubber material and is cut into a cylinder;
optionally, the cover body 1 may be sewn with a sand bag accommodating cavity at the lower end;
optionally, a rubber strip can be attached to the upper end of the sheath body 1; the attached rubber strip is parallel to the short side of the sheath body 1, and the rubber strip is annular after the zipper of the sheath body 1 is closed;
alternatively, in one possible embodiment, the tag counterweight 3 is designed as a cylinder, and the diameter of the tag counterweight is slightly smaller than that of the jacket body 1, and the length of the tag counterweight can be designed according to the counterweight requirement, and lead can be injected or tungsten alloy can be adopted if necessary.
Optionally, the jacket counterweight 2 may be a sand bag, and when the jacket counterweight 2 is a sand bag, the jacket body 1 needs to be sewed with a sand bag accommodating cavity at the lower end;
the invention is provided with the upper end friction block 4, so that the gravity of the pulling part of the sheath is borne by the upper end friction block instead of the whistle before the sheath is separated, thereby being capable of arbitrarily setting the diameter of the sheath within a certain limit and reducing the abrasion of the whistle; the design value of the maximum static friction force (depending on the diameter of the friction block) between the upper friction block 4 and the sheath body 1 is larger than the gravity of the sheath body 1 and smaller than the sum of the gravity of the sheath body 1 and the sheath counterweight 2, so as to avoid the sudden change of the external hanging load of the helicopter when the slogan sheath is pulled off, the maximum static friction force of the friction block is only slightly larger than the gravity of the sheath body, and a magic tape can be arranged between the friction block and the sheath to adjust the friction force if necessary.
The invention adopts the design of automatic pulling-out of the slogan, can effectively avoid the accidents of pulling-out and disfavored of the sheath and the early opening of the sheath, saves the labor required by pulling-out the sheath, and reduces the potential safety hazard of the external field.
The dimensions of the various pieces in fig. 1 are determined according to the actual task, and the order of the dimensions is as follows: the method comprises the steps of determining the weight of a tagline according to the length of the tagline, determining the lower limit of the diameter of a jacket according to the width of the tagline, determining the diameter, the length and the material of the tagline weight according to the diameter of the jacket, determining the length of the jacket according to the length of the tagline and the length of the tagline weight, determining the diameter of an upper friction block according to the weight of the jacket, determining whether a magic tape is added or not, and determining the weight of the jacket according to the maximum static friction force of the upper friction block.
Illustratively, the dimensions of each piece take 5mx14m slogan as an example, the sheath body 1 is long, 17m long and 1.4m wide, and 4 round holes with the diameter of 5cm are formed in the bottom; the sheath counterweight 2 is a cylinder formed by pouring cement, the radius of the bottom surface is 20cm, the height is 40cm, and the hook is buried in the cement to expose the upper part of the hook; the mass of the slogan counterweight 3 is 500kg, tungsten alloy is selected as a material, the counterweight is cast into a cylinder, the radius of the bottom surface of the counterweight is 20cm, and the height of the cylinder is 30cm; the upper friction block 4 is made of rubber, and is cut into a cylinder, the radius of the bottom surface of the cylinder is 23cm, and the height of the cylinder is 10cm.
The invention can solve the problem of difficult sheath pulling and escaping when the helicopter hangs the slogan for displaying and flying. After the friction block, the slogan, the sheath and the sheath counterweight are sequentially arranged, people can withdraw after the hook on the upper part of the friction block is connected with the hanging device of the helicopter, and the upper end friction block and the slogan are pulled up after the helicopter takes off. Because the maximum static friction force between the upper friction block and the inner surface of the slogan sheath is larger than the gravity of the sheath, the sheath is also pulled up. The helicopter continues to ascend, after the tagline sheath is completely pulled up, the counterweight of the tagline sheath, which is counteracted by the ground supporting force, is gradually transferred to the upper friction block, and when the maximum static friction force of the friction block is exceeded, the sheath is pulled off.
