Description
Technical field
The utility model relates to a kind of lift hanger, the hanger of especially a kind of manual operation for lifting test part,
Accurate installation for testpieces in Helicopter Main Reducer test.
Background technique
In Helicopter Main Reducer test, testpieces includes the lower half a coupler, taper casing and master combined
Retarder composition, for maximum weight up to 350kg, when test needs will be on 4 groups of 8 articulation holes and testing stand on taper casing
4 struts are connected by bolts, and when installing bolt, need to make the hinge on the oscillating bearing inner hole alignment taper casing on strut
Drilling position.But since the initial position of testpieces is not able to satisfy installation requirement generally, so needing to lift testpieces
And adjustment guarantees that bolt can pass through so that articulation hole to be aligned with the center of bearing hole, requires to meet support.
Traditional mode is testpieces to be propped by using jack, or do not fall lifting test part using jin, due to the position of installation
Required precision is higher, and the distance that testpieces needs to adjust is 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 lower, risk
It is larger.
Summary of the invention
The utility model provides a kind of manual hanger for lifting test part, can effectively improve Helicopter Main deceleration
Device in operational stability, the reliability when testing installation, can accurate Adjustment Tests part position, operational risk is greatly reduced,
And it is simple, convenient.
The technical solution of the utility model is the manual hanger for lifting test part, including sunpender, pillar,
Fixed handle, transverse slat, lifting handle, the sunpender are identical two, are mounted on fixed cross beam by attachment base respectively,
The lower part of sunpender is provided with external screw thread, and pillar is identical two, penetrates and can be slided up and down along sunpender from boom foot, is propped up
The fixed handle by being threadably mounted on sunpender is provided below in column, and the support frame being laterally extended is provided on pillar, support
The seam allowance for installing half a coupler is provided on frame；There are two mounting hole on transverse slat, lifting handle is identical two, is provided with
With the internal screw thread of sunpender lower thread cooperation, transverse slat is mounted on two sunpenders by two lifting handles, and transverse slat, which is provided with, to be prolonged
Center, gap for installing testpieces are reached, is provided with thrust bearing 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.
When the utility model is used, upper half a coupler is mounted on the support frame on pillar first, and seam allowance cooperates；
Then the lower half a coupler combined, taper casing and main reducing gear are lifted on transverse slat, wherein lower half a coupler with
Shaft between taper casing is located at the gap position of transverse slat, and then by two lifting handles of rotation, band motion plate is moved, into
And testpieces is moved, so that the articulation hole of testpieces is reached correct position, penetrate bolt, realizes taper casing and strut
Then upper half a coupler support frame is unclamped in connection, after the connection of upper and lower semiaxis shaft coupling, remove each component of hanger, tried
It tests.Fixed pitch of the utility model due to being provided with sunpender can pass through the amount of spin of calculating lifting handle, control examination
Test the move distance of part；The thrust bearing of setting, because bearing is rolling friction, frictional force is small, reaches labour-saving purpose.Cause
This, the utility model can effectively improve Helicopter Main Reducer in operational stability, reliability when testing installation, can be with
Accurate Adjustment Tests part position, is greatly reduced operational risk, and simple, convenient.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
The enlarged drawing of Fig. 2 lifting handle position；
Fig. 3 is the connection schematic diagram that taper casing passes through articulation hole and oscillating bearing and strut.
