Auxiliary gripper for folding large balloons

Abstract

The invention discloses an auxiliary clamp for folding large balloons and belongs to the technical field of large balloon folding and closing. The folding efficiency and quality of the large balloons are improved. The auxiliary clamp comprises a sleeve, elastic clamping pieces, force distribution plates and clamping plates. The two elastic clamping pieces are oppositely arranged on one side of the sleeve. One end of each elastic clamping piece is fixedly connected with the sleeve, the other end of the elastic clamping piece is provided with the corresponding arc-shaped force distribution plate. The middle of each elastic clamping piece and the middle of the corresponding force distribution plate are rotatably connected in the opening-closing direction. Concave faces of the two force distribution plates are arranged oppositely. The two ends of each force distribution plate are provided with the clamping plates correspondingly. The clamping plates and the force distribution plates are rotatably connected in the opening-closing direction or through universal spheres. The auxiliary clamp is used for folding the large balloons.

Description

technical field [0001] The invention belongs to the technical field of large-scale balloon folding, and in particular relates to an auxiliary fixture for folding a large-scale balloon. Background technique [0002] Large-scale balloons can be launched into the stratosphere as a remote information support platform. They have many advantages such as low cost, all-weather deployment, rapid deployment, rapid reconstruction, and long-term blanking time. However, large-scale balloons still exist Difficult to carry, there is no better folding method, the repeatability of the folding process is poor, the damage to the capsule is large, the volume after folding is still large, and the carrying space is wasted, so a multi-dimensional Z-shaped large-scale balloon folding method is designed. It includes the first step, straightening the north and south poles of the deflated balloon to the opposite direction; the second step, arranging the balloon into a regular radial star-shaped cross-...

[0002] Large-scale balloons can be launched into the stratosphere as a remote information support platform. They have many advantages such as low cost, all-weather deployment, rapid deployment, rapid reconstruction, and long-term blanking time. However, large-scale balloons still exist Difficult to carry, there is no better folding method, the repeatability of the folding process is poor, the damage to the capsule is large, the volume after folding is still large, and the carrying space is wasted, so a multi-dimensional Z-shaped large-scale balloon folding method is designed. It includes the first step, straightening the north and south poles of the deflated balloon to the opposite direction; the second step, arranging the balloon into a regular radial star-shaped cross-section; the third step, making the balloon Each of the sorted star petals is folded in a radial Z shape from outside to inside to further reduce the overall diameter; in the fourth step, each star petal sorted out by the balloon is synchronously folded in an axial Z shape from bottom to top Folding, the north pole of the balloon decreases with the folding progress; the folded balloon is close to a cylindrical shape; it has the advantages of simple folding process, easy operation, high folding efficiency, symmetrical folding shape, easy repeated folding, small volume after folding, and small folding damage. It has many advantages such as saving carrying space, and designing suitable tooling to assist in folding, which can further improve folding efficiency and quality. It includes a circular plane base, and a regular polygonal star-shaped row is arranged around the center of the plane base on the plane base. Fabric poles, the star-shaped arrangement of the poles must include the outer ring poles and the inner ring poles arranged in a staggered manner. When performing the second step of folding, the outer ring poles and the inner ring poles can be used to organize the balloon into a regular shape. Radial star shape, the inner ring pole is used to limit the reflex position of the star-shaped balloon, the outer ring pole is used to fix the star petal, and a clip should be set on each outer ring pole to fix the star petal , in order to better organize and overall shape the star petals, improve folding efficiency and quality, an auxiliary fixture for folding large balloons is designed
