Abstract
The present invention relates to a kind of ram-air turbine limit safety device, including pushing away dead man, only pulling out sleeve, gag lever post.One end of gag lever post is provided with a guide key groove, coordinates for the guide finger with fixed frame, limits the angular position of gag lever post.Gag lever post is provided with an inclined-plane, coordinates for the inclined-plane of the support arm with ram-air turbine, limits the position of support arm.The one end only pulling out sleeve is provided with external screw thread, for the screw-internal thread fit with fixed frame, limits the axial location of gag lever post.The present invention can prevent ram-air turbine from surprisingly stretching out during the ground maintenance of deployable and collapsible ram-air turbine, reduces and safeguards risk, improves safety.
Description
Technical field
The present invention relates to a kind of ram-air turbine limit safety device, be mainly used in deployable and collapsible punching press empty
Air turbine.
Background technology
At present ram-air turbine is lacked corresponding limit safety device, for this defect, study.
Summary of the invention
Design the limit safety device of a kind of deployable and collapsible ram-air turbine, prevent ram-air turbine on ground
Surprisingly stretch out when face is safeguarded, reduce and safeguard risk, improve safety.
A kind of limit safety device of ram-air turbine, including gag lever post group and stationary frame structure, spacing
Bar group includes pushing away dead man, only pulling out sleeve and gag lever post, pushes away dead man through only pulling out sleeve and is connected to one with gag lever post
Rise, and be connected by pin rod with only pulling out sleeve；Gag lever post is provided with an inclined-plane and a guide key groove, tiltedly
Face coordinates for the support arm with ram-air turbine, limits the position of support arm, and guide key groove is used for and solid
Determine frame structure to coordinate；The one end only pulling out sleeve is provided with external screw thread, for the interior spiral shell with stationary frame structure
Stricture of vagina coordinates, and limits the axial location of gag lever post；Stationary frame structure include ram-air turbine correct frame and
Left frame.
The correct frame of ram-air turbine is provided with a hole, and the side in hole is provided with one and described feather key
The guide finger of slot fit.
The left frame of ram-air turbine is provided with the screwed hole coordinated with described external screw thread.
The support arm of ram-air turbine is provided with an inclined-plane coordinated with the inclined-plane of described gag lever post.
Reliability is high, after the limit safety device of present invention design is correctly installed, can be limited by ram-air turbine
It is scheduled on recovery position.Destroying this restriction to need to cut off gag lever post, probability of happening is the most impossible.
Simple for structure, whole limit safety device only has three parts compositions.
Easy accessibility.

Detailed description of the invention
Below in conjunction with Figure of description and embodiment, the present invention is described in further detail.Refer to
Bright book accompanying drawing 1～7.
When using the limit safety device that the present invention relates to, ram-air turbine necessarily be in recovery lock-out state.
During use, limit safety device 23 is arranged between left frame 24 and correct frame 22, defines support arm 21
Position.
Installation process the following detailed description of limit safety device.
Gag lever post 3 is provided with an inclined-plane 31 and a guide key groove 32.The correct frame of ram-air turbine
22 are provided with a hole 41, and the side in hole 41 is provided with a guide finger 42.During installation, it is directed to keyway
32 alignment guide pins 42, insert gag lever post 3 in hole 41.
The one end only pulling out sleeve 2 is provided with external screw thread 51.The left frame 24 of ram-air turbine is provided with screw thread
Hole 61.To only pull out sleeve 2 and screw in screwed hole 61, until gag lever post 3 is compressed.
Support arm 21 is provided with an inclined-plane 71, and after gag lever post 3 is compacted, inclined-plane 31 is tight with inclined-plane 71
Closely connected conjunction, thus define the position of support arm 21.
