A kind of ground effect ship motor car engine its Test Rig, comprise base, the stand bearing of four quadrangularly vertical support is installed on described base, on described stand bearing, be horizontally installed with swing stand, one end of described swing stand extends the outside of stand bearing, and the upper portion of described swing stand is provided with the engine mounting platform that engine is installed; The top that is positioned at each stand bearing is provided with bolt support, and the inside that is positioned at each stand bearing is provided with swing arm hanger, the bottom of described swing arm hanger is connected with swing stand, the top of described swing arm hanger is connected with bolt support by bolt, and described swing arm hanger forms parallelogram with swing stand and swings supporting structure.
Further improvement as technique scheme:
Be positioned on the swing stand of stand bearing outside front support stand is also installed, described front support stand is vertical with swing stand, parallel with the front support stand rear support stand that is also provided with, described rear support stand is fixed on ground, between described front support stand and rear support stand, is connected with thrust pickup;
On described engine mounting platform, Connection Block is installed, on described Connection Block, engine support is installed, engine is installed on engine support;
The center line of front support stand, thrust pickup and rear support stand and the center line of engine are on same straight line;
Described engine mounting platform is welded in and swings on stand;
Between adjacent two stand bearings, reinforcing whippletree is installed, on described reinforcing whippletree, by securing member, limited block is installed.
The beneficial effects of the utility model are as follows:
(1) the utility model is rational in infrastructure, compact, easy to make.
(2) the utility model power transmission is effective.Adopt the swinging mounting structure of parallelogram as power transmission platform structure, reduce greatly the frictional resistance in mechanical drive, improved transmission effect.
(3) usable range is wide.The utility model can meet the bench test of the motor car engine Marine transformation of Multiple Type, and can meet the bench test demand of 400 horsepowers of following various model aeromotors, uses flexibility and reliability.
(4) measurement data is accurate.Pressure type load sensor of the present utility model can regulate fixing position, in the bracing frame of front and back, move up and down, its center line can remain with tested engine centerline point-blank, reduced the impact of torsion on sensor.
(5) integrated innovation of the utility model to conventional motor car engine its Test Rig and small-sized aviation piston engine its Test Rig, is applied to small aero and general-utility car engine modification and becomes the stand after ground effect ship power to measure test.
