In technique scheme, described base is provided with kidney slot, and described floor upper surface is provided with T-slot, and coupling bolt is connected this base with T-slot by kidney slot with the floor.
In technique scheme, be connected by web joint on the described adjusting screw mandrel with between the back-up block, described web joint is fixed in the back-up block lower end, web joint is connected by shoulder hole with regulating between the screw mandrel, regulating the spacing ring that also is provided with axial limiting on the screw mandrel, described spacing ring is positioned at the web joint below and is enclosed within to be regulated on the screw mandrel.
In technique scheme, described spacing ring is positioned at the web joint below and is enclosed within to be regulated on the screw mandrel, and described spacing ring is provided with screw, and described screw passes spacing ring and is fixed on the adjusting screw mandrel.
In technique scheme, described kidney slot direction is vertical with the T-slot direction.
The flexible adjustable supports of engine rig test of the present utility model, have following beneficial effect: since be used to support engine mounting back-up block can with regulate screw mandrel and move up and down synchronously, and being provided with of base kidney slot and iron floor T-slot helps be supported on moving about front and back on the horizontal direction, make this support can satisfy the testing requirements of different size engine, solve original support and used single problem, satisfied engine 3 points, four point-supported installation requirements.Simultaneously, support with respect to existing fixed, the flexible adjustable supports of engine rig test is more safe and reliable.
Below in conjunction with drawings and Examples the utility model is described in further detail, but this embodiment should not be construed as restriction of the present utility model.

Embodiment
Referring to Fig. 1, on the flexible adjustable supports of engine rig test described in the utility model floor 15 be fixed on the concrete foundation that has vibration isolator, to avoid because engine vibration is given the engine rig test adverse effect that flexible adjustable supports is brought.In the present embodiment, floor 15 used materials are cast iron, also can be other metal materials.Simultaneously, floor 15 is provided with T-slot 14, and the base 5 of the flexible adjustable supports of described engine rig test is connected with floor 15 by four fastening bolts, and described base 5 can move the distance that suspends before and after the engine to guarantee along the direction of T-slot 14.
Referring to Fig. 2 to Fig. 4, the engine (not shown) suspends and is installed on the back-up block 1, four screw retention of this back-up block 1 usefulness are above web joint 2, and described web joint 2 is welded on support bar 3 upper ends, and described back-up block 1, web joint 2 and support bar 3 form a whole.Described support bar 3 belows are supports 6, and these support bar 3 lower ends are vertically stretched in the described support 6, and this support 6 is welded on the base 5, and support 6 is formed a rigid body with base 5.Be screwed on support 6 nut seat 8 can with regulate screw mandrel 4 and cooperate, this adjusting screw mandrel 4 is connected with back-up block 1, and with web joint 2 between be connected by shoulder hole 13, described adjusting screw mandrel 4 passes through web joint 2 and links to each other with support bar 3.Described adjusting screw mandrel 4 also is provided with the spacing ring 9 of axial limiting, and described spacing ring 9 is positioned at web joint 2 belows and is enclosed within to be regulated on the screw mandrel 4.Rotate and cooperate when moving up and down when regulating screw mandrel 4 and nut seat 8, because spacing ring 9 is resisted against on the web joint 2, so can drive web joint 2, support bar 3 and back-up block 1 moves up and down synchronously with regulating screw mandrel 4, its range of adjustment can cover the altitude range that existing planer-type supports and the screw mandrel formula supports between 450～700mm.Be provided with latch segment 7 between support 6 and support bar 3, described latch segment 7 can be locked support bar 3 with 3 movable connections also of support bar.Also be provided with gusset 10 on the flexible adjustable supports of described engine rig test, described gusset 10 welds with base 5 and support 6 respectively for the rigidity that improves support 6.
