Detailed Description
The following explains the automatic pull-off slogan jacket provided by the present invention with reference to the accompanying drawings.
Fig. 1 is a schematic structural diagram of an automatic pull-off banner jacket according to the present invention, and as shown in fig. 1, the present invention provides an automatic pull-off banner jacket, including: the jacket comprises a jacket body 1, a jacket counterweight 2, a slogan counterweight 3 and an upper end friction block 4.
Illustratively, the sheath body 1 is of a strip-shaped structure, the lower end of the sheath body is provided with a plurality of openings, the sheath body is made of canvas or jean, and sectional zippers are arranged on two sides of the sheath body;
the sheath counterweight 2 is a cylinder poured by cement, and a hook is buried and exposed out of the upper part of the hook;
the slogan counterweight 3 is a cylinder cast by metal, and the material can be selected from high-density metal such as steel or tungsten alloy according to the task condition;
the upper end friction block 4 is made of rubber and is cut into a cylinder;
optionally, the lower end of the sheath body 1 can be sewn with a sandbag accommodating cavity;
optionally, a rubber strip can be additionally attached to the upper end of the sheath body 1; the attached rubber strip is parallel to the short edge of the sheath body 1, and the rubber strip is annular after the zipper of the sheath body 1 is closed;
optionally, in a possible embodiment, the slogan weight 3 is designed to be a cylinder, and the diameter of the cylinder is slightly smaller than that of the sheath body 1, and the length of the cylinder can be designed according to the weight requirement, and lead can be injected or a tungsten alloy material can be adopted as necessary.
Optionally, the sheath counterweight 2 can also be a sand bag, and when the sheath counterweight 2 is the sand bag, the sheath body 1 needs to sew a sand bag accommodating cavity at the lower end;
the upper end friction block 4 is arranged, so that the gravity of the pulled part of the sheath is borne by the upper end friction block instead of the slogan before the sheath is detached, the diameter of the sheath can be randomly set within a certain limit, and meanwhile, the abrasion of the slogan is reduced; the maximum static friction force (depending on the diameter of the friction block) of the upper-end friction block 4 and the sheath body 1 is greater than the gravity of the sheath body 1 and less than the sum of the gravity of the sheath body 1 and the sheath counter weight 2, so that the sudden change of the hanging load outside the helicopter is too large when the slogan sheath is pulled off, the maximum static friction force of the friction block only needs to be slightly greater 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 when necessary.
The invention adopts the slogan automatic pull-off design, can effectively avoid sheath pull-off loss and sheath early opening accidents, saves the labor required for pulling off the sheath and reduces the potential safety hazard of an outfield.
The sizes of the parts in fig. 1 need to be determined according to actual tasks, and the order of size determination is as follows: determining the weight of the slogan counterweight according to the length of the slogan, determining the lower limit of the diameter of the sheath according to the width of the slogan, determining the diameter, the length and the material of the slogan counterweight according to the diameter of the sheath, determining the length of the sheath according to the length of the slogan counterweight and the length of the slogan counterweight, determining the diameter of the upper friction block and whether a magic tape is added according to the mass of the sheath, and determining the weight of the sheath counterweight according to the maximum static friction force of the upper friction block.
Illustratively, the sizes of the parts are 5mx14m, the sheath body 1 is in a strip shape, the length is 17m, the width is 1.4m, and 4 circular holes with the diameter of 5cm are formed at the bottom; the sheath counterweight 2 is a cylinder poured by 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, the material is tungsten alloy, and the slogan counterweight is cast into a cylinder, the radius of the bottom surface of the cylinder is 20cm, and the height of the cylinder is 30 cm; the upper end friction block 4 is made of rubber and is cut into a cylinder, and the radius of the bottom surface of the cylinder is 23cm, and the height of the cylinder is 10 cm.
The invention can solve the problem that the sheath is difficult to pull off when the helicopter hangs the slogan display flight. After the friction block, the slogan, the sheath and the sheath counterweight are sequentially arranged, personnel can evacuate after the hook at the upper part of the friction block is connected with the helicopter hanging device, and the upper friction block and the slogan are pulled up after the helicopter takes off. Because the maximum static friction force between the upper end 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 rise, when the slogan sheath is completely pulled up, the balance weight of the slogan sheath, which is originally offset by the ground support force, is gradually transferred to the friction block at the upper end, and when the maximum static friction force of the friction block is exceeded, the sheath is pulled off.
