Description
Technical field
The invention belongs to parachute technology field, and in particular to a kind of umbrella roof construction of disk-gap-band parachute.
Background technology
For a kind of instrument for the safe falling that slows down when parachute is under placement in height, wherein, disk-gap-band parachute is that one kind has
The parachute of excellent decelerability, there is good stability, the stable whereabouts of hanger can be ensured when in use.Good
Performance increases its use range, and in deep-space detection field, disk-gap-band parachute has irreplaceable application advantage, and deep space probing
The decelerating effect of the varicoloured seam umbrella that do not open the set.
It is provided with a umbrella apical pore at the top of the canopy disk of in general disk-gap-band parachute, the air-flow velocity ratio of umbrella apical pore is flowed through during parachute-opening
It is larger, in order to ensure the intensity of umbrella apical pore and mechanical characteristic, it will usually use interlaced radiation reinforcing strip at umbrella apical pore
Umbrella apical pore is strengthened, and suture fixation will not be carried out between different radiation reinforcing strips.According to need at the top of the umbrella of disk-gap-band parachute
Corresponding device can be installed by asking, and under the use condition of routine, the umbrella top intensity of disk-gap-band parachute is sufficient for using and wanted, can be normal
Use.
But if need to install the device of constant weight at the top of disk-gap-band parachute, due to the radiation reinforcing strip phase on umbrella top
Do not fixed between mutually so that there is unstability between the device and installation fixing point of the installation of umbrella top, installation can only be about when fixed
Beam lives the device along the motion on umbrella cover axial direction, but can not constrain the motion along radiation reinforcing strip direction so that device is in parachute-opening
During, umbrella top center is left under overload and the double action of impact acceleration and is slided along single radiation reinforcing strip, it is single
Radiation reinforcing strip can bear the power of whole device, while the limited strength of single layer radiation reinforcing strip, and local pressure is excessive easily to lead
Single radiation reinforcing strip is caused to be broken, device separates with umbrella, has influence on the function of parachute.The fracture of radiation reinforcing strip can also influence
Access times or life-span, the security performance of extreme influence parachute, cause umbrella body to occur in parachute damaged, or even safety occur
Accident.The intensity of enhanced rad reinforcing strip, while it is that current disk-gap-band parachute field is badly in need of solving to prevent that erecting device from slidably reciprocating
One of the problem of.
The content of the invention
For the disadvantages described above or Improvement requirement of prior art, the present invention provides a kind of umbrella roof construction of disk-gap-band parachute,
Increase short reinforcing strip in radiation reinforcing strip, can effectively increase the intensity of radiation reinforcing strip, radiation reinforcing strip is sewn in order
Together, the force-bearing situation of radiation reinforcing strip can effectively be improved, and the circle of increase by two circumferential strengthening band can in radiation reinforcing strip

2nd, the third and fourth circumferential strengthening band is used for spacing to the device progress for being installed on the umbrella top, while strengthens umbrella top spoke
Penetrate the structural strength of reinforcing strip.
Further, the bar number close to the umbrella top of circle centre position radiation reinforcing strip in umbrella apical pore is less than the gores
The bar number of the upper umbrella top radiation reinforcing strip, close to a umbrella top of circle centre position, radiation reinforcing strip is to be radiated to strengthen by a plurality of umbrella top
Band is formed by stacking, for increasing the intensity of the umbrella top radiation reinforcing strip at the umbrella apical pore.
Further, the radius of first circumferential strengthening band and the 3rd circumferential strengthening band is about that the umbrella top circumference is strengthened
1/3rd with radius.
Further, radiation reinforcing strip in umbrella top is added by the length of a plurality of overlapping section being formed by stacking more than second circumference
The length of the diameter of strong band.
Further, the distance between first circumferential strengthening band and second circumferential strengthening band are 10~20mm.
Further, the umbrella top circumference reinforcing strip, first circumferential strengthening band, second circumferential strengthening band, institute
State the width all same of the 3rd circumferential strengthening band and the 4th circumferential strengthening band.
Further, the short reinforcing strip is fixedly connected on the back of the body of the umbrella top radiation reinforcing strip by the way of two ways
Portion.
In general, by the contemplated above technical scheme of the present invention compared with prior art, it can obtain down and show
Beneficial effect：
(1) the umbrella roof construction of disk-gap-band parachute of the present invention, short reinforcing strip is set by radiating reinforcing strip back on every umbrella top
The intensity of increase radiation reinforcing strip, set four circle circumferential strengthening bands both to serve position-limiting action in umbrella apical pore, while can have
Effect improves the stress on disk-gap-band parachute umbrella top, ensures the intensity and function of disk-gap-band parachute when in use, and effectively reduce and be somebody's turn to do
The use cost of type parachute.
(2) the umbrella roof construction of disk-gap-band parachute of the present invention, one is synthesized by the way that the multiply in umbrella apical pore is radiated into reinforcing strip, is increased
Add the umbrella top in umbrella apical pore to radiate the intensity of reinforcing strip, prevent from causing umbrella top radiation reinforcing strip fracture because single stress is excessive,
Influence the security performance of disk-gap-band parachute.
