Description
Technical field
The present invention relates to the hangers of a kind of lift hanger, especially a kind of manual operation for lifting test part, are used for
The accurate installation of testpieces in Helicopter Main Reducer experiment.
Background technology
In Helicopter Main Reducer experiment, testpieces includes the lower half a coupler, taper casing and master combined
Retarder forms, maximum weight up to 350kg, when experiment need by 4 groups of 8 articulation holes on taper casing on testing stand
4 struts be connected by bolts, in installation bolt, need to make on strut oscillating bearing endoporus alignment taper casing on
Articulation hole site.But since the initial position of testpieces cannot generally meet installation requirement, so needing to carry testpieces
It rises and adjustment ensures that bolt can pass through, wanted to meet support so that articulation hole to be aligned with the center of bearing hole
It asks.Traditional mode is to prop testpieces by using jack, or do not fall lifting test part using jin, due to the position of installation
Set that required precision is higher, testpieces needs the distance adjusted controllable, and these method operational stabilities are poor, can not accurately be controlled
System, is easy Scratch Test part during the installation process, and can not intense adjustment testpieces position, therefore reliability is relatively low, risk
It is larger.
Invention content
The present invention provides a kind of manual hangers for lifting test part, can effectively improve Helicopter Main Reducer and exist
Testing operational stability when installing, reliability, can accurate Adjustment Tests part position, operational risk is greatly reduced, and grasp
Make simply, conveniently.
The technical scheme is that the manual hanger for lifting test part, including sunpender, pillar, fixation
Handle, transverse slat, lifting handle, the sunpender are identical two, are mounted on fixed cross beam by connecting seat respectively, sunpender
Lower part be provided with external screw thread, pillar is identical two, penetrates and can be slided up and down along sunpender from boom foot, under pillar
Face is provided with the fixed handle being threadably mounted on sunpender, is provided with the supporting rack being laterally extended on pillar, on supporting rack
It is provided with the seam allowance for installing half a coupler；Mounting hole there are two on transverse slat, lifting handle are identical two, are provided with and hang
The internal thread of bar lower thread cooperation, transverse slat are mounted on by two lifting handles on two sunpenders, and transverse slat, which is provided with, to be extended to
Center, gap for installing testpieces, thrust bearing is provided between the lifting handle and transverse slat.
The screw pitch of the screw thread of the sunpender lower part is 2mm.
Band step bushing is provided on the lifting handle, thrust ball bearing is between bushing and handle nut.
In the use of the present invention, upper half a coupler is mounted on the supporting rack on pillar first, and seam allowance coordinates；Then
The lower half a coupler combined, taper casing and main reducing gear are lifted on transverse slat, wherein lower half a coupler and taper
Shaft between casing is located at the gap position of transverse slat, and then by rotating two lifting handles, band motion plate moves, and then makes
Testpieces is moved, and so that the articulation hole of testpieces is reached correct position, is penetrated bolt, realizes the company of taper casing and strut
It connects, then unclamps upper half a coupler supporting rack and remove each component of hanger after connecting upper and lower semiaxis shaft coupling, tried
It tests.The present invention can pass through the amount of spin of calculating lifting handle, Control experiment part due to the fixed pitch provided with sunpender
Move distance；The thrust bearing of setting, because bearing is rolling friction, frictional force is small, reaches labour-saving purpose.Therefore, originally
Invention can effectively improve Helicopter Main Reducer and test operational stability when installing, reliability, can accurately adjust
Operational risk is greatly reduced in testpieces position, and simple, convenient.
