Abstract
The invention relates to a limiting safety device of a ram air turbine. The limiting safety device comprises a push and pull rod, a pull-stopping sleeve and a limiting rod, wherein a guide key groove is formed in one end of the limiting rod, and is matched with a positioning pin of the ram air turbine so as to limit the angle direction and position of the limiting rod, the limiting rod is provided with an oblique surface, the oblique surface is matched with a limiting surface of a support arm of the ram air turbine so as to limit the position of the support arm, the push and pull rod is riveted with the limiting rod, the pull-stopping sleeve can slide along the polished rod part of the push and pull rod, one end of the pull-stopping sleeve is provided with external threads, and the external threads are matched with internal threads of the ram air turbine so as to limit the axial position of the limiting rod. The limiting safety device has the advantage that in the ground maintenance process of the retractable type ram air turbine, the accidental extending of the ram air turbine is prevented, so the maintenance risk is decreased, and the safety is improved.
Description
Technical field
The present invention relates to a kind of ram-air turbine limit safety device, be mainly used in deployable and collapsible ram-air turbine.
Background technique
At present corresponding limit safety device is lacked to ram-air turbine, for this defect, study.
Summary of the invention
Design a kind of limit safety device of deployable and collapsible ram-air turbine, prevent ram-air turbine from surprisingly stretching out when ground maintenance, reduce and safeguard risk, improve Security.
A kind of limit safety device of ram-air turbine, comprise position-limited lever group and stationary frame structure, position-limited lever group comprises and pushes away dead man, only pulls out sleeve, position-limited lever, push away dead man and position-limited lever is fixed together, position-limited lever is provided with an inclined-plane and a guide key groove, inclined-plane is used for coordinating with the guide finger of ram-air turbine, limits the position of support arm; The one end of only pulling out sleeve is provided with outside thread, for the screw-internal thread fit with ram-air turbine, limits the axial position of position-limited lever; Stationary frame structure comprises the right frame of ram-air turbine, left frame and support arm.
The right frame of ram-air turbine is provided with a hole, and the side in hole is provided with a guide finger.
The left frame of ram-air turbine is provided with tapped hole.
The support arm of ram-air turbine is provided with an inclined-plane.
Reliability is high, after the limit safety device that the present invention designs correctly is installed, ram-air turbine can be limited to and reclaim position.Destroy this restriction to need to cut off position-limited lever 3, probability of happening is extremely impossible.
Simple for structure, whole limit safety device is only made up of three parts.
Easy accessibility.

Embodiment
Below in conjunction with Figure of description and embodiment, the present invention is described in further detail.Refer to Figure of description 1 ~ 7.
When using the limit safety device that the present invention relates to, ram-air turbine must be in recovery lock state.During use, limit safety device 23 is arranged between left frame 24 and right frame 22, defines the position of support arm 21.
The following detailed description of the installation process of limit safety device.
Position-limited lever 3 is provided with an inclined-plane 31 and a guide key groove 32.The right frame 22 of ram-air turbine is provided with a hole 41, and the side in hole 41 is provided with a guide finger 42.During installation, by guide key groove 32 alignment guide pin 42, in position-limited lever 3 patchhole 41.
The one end of only pulling out sleeve 2 is provided with outside thread 51.The left frame 24 of ram-air turbine is provided with tapped hole 61.Only will pull out sleeve 2 to screw in tapped hole 61, until position-limited lever 3 is compressed.
Support arm 21 is provided with an inclined-plane 71, and after position-limited lever 3 is compacted, inclined-plane 31 and inclined-plane 71 fit tightly, thus define the position of support arm 21.
