Abstract

A multi-point bearing loop for an aerostat comprises a plurality of bridles and a loop bottom which is arranged on an aerostat skin, wherein the loop bottom is arranged on the aerostat skin and the bridles are annularly distributed on the loop bottom; the loop bottom is an elliptic multi-layer structure; and the two ends of each bridle are fixed on the loop bottom and form V-shaped structures. The multi-point bearing loop for the aerostat bears the load in multiple points to disperse the load so that the bearing capacity of the loop is enhanced and the bridles are prevented from being separated from the loop; and upper bridles and lower bridles work standby for each other so that the reliability of the structure is enhanced.

Description

Aerostatics many point bearings loop

Technical field

The present invention relates to the technology in a kind of aerostatics field, specifically a kind of aerostatics many point bearings loop.

Background technology

High low latitude aerostatics has a wide range of applications in fields such as space science, communication, observation and remote sensing. What aerostatics itself undertook is aerial mission, also needs to the corresponding equipment of carry for tasks such as communication, observations. Safety and stablization for support equipment, it is necessary to the load-bearing loop as erecting by overhang has good weight capacity, and loop itself to have enough intensity simultaneously, it is prevented that tears, separate.

What the loop major part on present aerostatics adopted is round bottom loop, one bridle is set at the bottom of loop, connected mode at the bottom of this loop and between bridle determines this round bottom loop and can only bear the pulling force in a direction, side force or opposite force and can cause tearing at the bottom of loop and between bridle or separating. And suspension equipment is often subject to wind load and rotates in aerostatics flight course, there is certain change in the direction of pulling force, at this moment round bottom loop cannot ensure the safety of suspension equipment.

Through the retrieval of prior art is found, Chinese patent literature CN203229081U, publication date is on October 09th, 2013, discloses a kind of resistance to bicircular cylindricality container bag. As shown in Figure 1, this device includes bag, the above of bag opens charging aperture, charging aperture place arranges the barrel that connect internal with bag, and barrel arranges the binder that links closely, and bag is provided with some block pieces, being provided below of block piece can be used for the covering hindering foreign material to enter barrel, some suspender belts are sewn on bottom surface and the side of bag, and this suspender belt is cruciform shape in bottom surface, and the folding sewing in the end of suspender belt forms handle on suspender belt. But the handle in this device is used for promoting bag, and cannot suspension arrangement.

Summary of the invention

The present invention is directed to prior art above shortcomings, it is proposed to a kind of aerostatics many point bearings loop.

The present invention is achieved by the following technical solutions:

The present invention includes: be arranged at the bottom of the loop on aerostatics eyelid covering and several bridles at the bottom of in loop that are periphery, and wherein: ovalize at the bottom of loop and be multiple structure, the two ends of each bridle are fixed at the bottom of loop and form V-shaped structure.

It is preferably ultra high molecular polyethylene material makes with bridle at the bottom of described loop.

Major axis radius at the bottom of described loop is 200mm, and minor axis radius is 150mm.

The long 160mm of described bridle, wide 50mm, its two ends are fixed at the bottom of loop by sewing mode.

Technique effect

Compared with prior art, the present invention is many, and point bearing has disperseed load, increases the bearing capacity of loop, avoids the separation of bridle and loop, upper bridle and lower bridle to backup each other simultaneously, adds reliability of structure.

Accompanying drawing explanation

Fig. 1 is the structural representation of prior art;

Fig. 2 is the floor map of the present invention;

Fig. 3 is the sewing mode schematic diagram of bridle;

In figure: 1 handle; At the bottom of 2 loops; 3 bridles.

Detailed description of the invention

Below embodiments of the invention being elaborated, the present embodiment is carried out under premised on technical solution of the present invention, gives detailed embodiment and concrete operating process, but protection scope of the present invention is not limited to following embodiment.

Embodiment 1

As in figure 2 it is shown, the present embodiment includes: at the bottom of four bridles 3 and loop 2, wherein: at the bottom of loop, 2 are adhesive on aerostatics eyelid covering, the two ends of each bridle 3 are fixed at the bottom of loop on 2 by the mode sewed.

At the bottom of described loop, 2 is multiple structure, and multilamellar refers to that number of layers is more than two-layer, is the overlapping of double-layer structure and materials at two layers in the present embodiment, and ovalize, and its long axis length a is 400mm, minor axis length b is 300mm. At the bottom of loop 2 and the ultra high molecular polyethylene bag material that material is high-strength light of bridle 3, its surface density is less than 100g/m², intensity is more than 300N/cm.

As it is shown on figure 3, described bridle 3 is also multiple structure, being four-layer structure in the present embodiment, each layer of bridle 3 is connected by sewing mode, and this bridle 3 is long is 160mm, wide 50mm, and material therefor is also bag material, and four bridles 3 are periphery at the bottom of loop 2, forms similar square. After this bridle 3 is folded into V-shaped, two ends are sewn at the bottom of loop on 2.

The many point bearings of this device have disperseed load, increase the bearing capacity of loop, avoid the separation of bridle and loop simultaneously. Many point bearings loop is greatly improved compared to single-point load-bearing loop load capacity, can reach 520kg, and bridle backups each other up and down, adds reliability of structure.

Claims

1. aerostatics many point bearings loop, it is characterized in that, including: being arranged at the bottom of the loop on aerostatics eyelid covering and several bridles at the bottom of in loop that are periphery, wherein: ovalize at the bottom of loop and be multiple structure, the two ends of each bridle are fixed at the bottom of loop and form V-shaped structure.

2. aerostatics many point bearings loop according to claim 1, is characterized in that, at the bottom of described loop and bridle be that ultra high molecular polyethylene material is made.
