Detailed description of the invention
Fig. 1 is test bay rack general illustration provided by the invention；
Fig. 2 is test bay carriage portion structural schematic diagram provided by the invention；
Fig. 3 is test bay carriage portion structural schematic diagram provided by the invention.
Specific embodiment
With reference to the accompanying drawing and embodiment the invention will be further described.Wherein, attached drawing only for illustration,
What is indicated is only schematic diagram, rather than pictorial diagram, should not be understood as the limitation to this patent；Reality in order to better illustrate the present invention
Example is applied, the certain components of attached drawing have omission, zoom in or out, and do not represent the size of actual product；To those skilled in the art
For, the omitting of some known structures and their instructions in the attached drawings are understandable.
As shown in Figure 1, 2, 3, the present invention provides a kind of Used For Turbojet Engine Test Bench rack, including mounting platform 1, hair
Motivation mounting rack；Motor mounts include quiet frame 2, moving frame 3, adapter frame 4；Quiet frame 2 is fixed on mounting platform 1, uses peace
Assembling platform is conducive to the extension of test bay function, motor mounts can be replaced with adapt to the engine of other models use,
It is equipped with adjusting pad 21 between the pillar and mounting platform of quiet frame 2, is leveled for quiet frame.
Moving frame is hung on inside quiet frame by four pieces of steel spring plates 5: being leaned on the inside of the upper end of leaf spring 5 and quiet 2 top beam of frame
The vertical connection block at nearly angle end is fixedly connected, and its lower end is fixedly connected with 3 four columns of moving frame, as shown, due to bullet
The presence of spring steel plate, when engine is tested, generating thrust can be such that moving frame carries out by a small margin along engine axis direction
Swing；The top surface and side of moving frame upper beam are equipped with multiple pin holes, and the two sides of quiet frame are equipped with four safety pins 8 altogether, Gu
Positioning is set with steel spring plate fixed position in orthogonal plane, and safety pin 8 is inserted into 3 upper beam side institute cloth of moving frame
In the pin hole set, so, if failed in steel spring plate 5, fallen on safety pin 8 under moving frame 3, to guarantee engine
