A plurality of shock absorption rubber cushions 7 are arranged between the shock absorption platform 2 and the motor frame 1 for shock absorption. The damping table 2 and the motor frame 1 are fixedly connected through bolts. The damping table 2 is provided with a belt hook 8, and when the belt is not connected with the compressor 9, the belt can be hung on the belt hook 8.

The test platform 3 is used for mounting a compressor 9 to be tested. The test platform 3 comprises a fixed workbench 31 fixed on the damping table 2, an adjusting workbench 32 connected with the fixed workbench 31 in a sliding manner, and a compressor bracket 33 fixedly connected with the adjusting workbench 32. The compressor 9 is mounted to the compressor bracket 33. The adjusting workbench 32 is provided with a slide rail 321, the fixed workbench 31 is provided with a slide groove 322 matched with the slide rail 321, and the relative position relationship between the adjusting workbench 32 and the fixed workbench 31 can be adjusted through the slide rail 321 and the slide groove 322, so that the position of the compressor bracket 33 is adjusted, and further the position of the compressor 9 is adjusted, and the compressor 9 is in a proper installation position.

The driving mechanism 4 comprises a variable frequency motor 41 and a belt pulley 42 connected with the variable frequency motor 41, and the belt pulley 42 is connected with a main shaft of the variable frequency motor 41 through a flat key 43. The pulley 42 is adapted to be connected to the compressor 9 by a belt. The variable frequency motor 41 drives the belt pulley 42 to rotate, so as to drive the rotating shaft of the compressor 9 to rotate, and the service life of the compressor 9 is tested. In order to test the compressor 9 at ultra high speed, the outer diameter of the belt pulley 42 is 4-5 times of the outer diameter of the rotating shaft of the compressor 9, namely, the transmission ratio of the belt pulley 42 to the rotating shaft of the compressor 9 is 4-5. In this embodiment, an ultra high speed experiment at a rotation speed of 11000rpm may be performed on the compressor 9. In addition, the variable frequency motor 41 can perform a high-speed and low-speed variable frequency speed regulation experiment on the compressor 9, so that the reliability of the product is verified.

The adjusting device 5 comprises a supporting plate 51 for mounting the variable frequency motor 41, an adjusting mechanism for adjusting the position of the supporting plate 51 and a limiting block 52 for limiting the supporting plate 51.

The support plate 51 has a first hinge base 53 at one end and a second hinge base 54 at the other end. One end of the support plate 51 is detachably connected to the first hinge base 53, and the other end is detachably connected to the second hinge base 54. Specifically, the first hinge base 53 and the second hinge base 54 are respectively fixed to the support plate 51 by bolts.

The adjustment mechanism includes a first adjustment mechanism located at one end of the pallet 51 and a second adjustment mechanism located at the other end of the pallet 51.

The first adjusting mechanism includes a first hinge 55 and a hinge fixing seat 56, one end of the first hinge 55 is hinged to the first hinge seat 53, and the other end is hinged to the hinge fixing seat 56. The hinge fixing seat 56 is fixed on the motor frame 1. The first hinge 55 is hinged to the first hinge base 53 at the first hinge point a and is hinged to the hinge fixing base 56 at the second hinge point B.

The second adjusting mechanism comprises a second hinge 57, a nut 58, a screw 59, and a screw fixing seat 510 for mounting the screw 59, wherein the screw fixing seat 510 is fixedly connected to the motor frame 1. One end of the second hinge 57 is hinged to the second hinge base 54, the other end is hinged to the nut 58, the nut 58 is in threaded fit connection with the screw rod 59, and the screw rod 59 extends in the up-down direction. The second hinge 57 is hinged to the third hinge point C with the second hinge base 54, and is hinged to the fourth hinge point D with the nut 58.

Wherein a distance D1 between the first hinge point a and the second hinge point B is equal to a distance D2 between the third hinge point C and the fourth hinge point D (i.e., D1 is D2). The distance d3 between the first hinge point a and the supporting plate 51 is equal to the distance d4 between the third hinge point C and the supporting plate 51 (i.e., d3 is d 4). And the ratio of the distance d5 between the first hinge point A and the third hinge point C to the distance d1 between the first hinge point A and the second hinge point B is 5-8 (i.e. d5/d1 is 5-8). By these arrangements, the entire adjustment mechanism can be made more suitable for adjustment.

The limiting block 52 is fixed on the motor frame 1 and located below the supporting plate 51, and when the position of the supporting plate 51 is adjusted, the limiting block 52 can limit the position.

The screw 58 can be driven to move upwards or downwards by the rotation of the screw 59, and the second hinge 57 drives the supporting plate 51 to move upwards or downwards by the driving of the screw 58 and has a proper inclination angle. Correspondingly, the compressor bracket 33 may also allow the compressor 9 to be installed at an appropriate angle, so that the rotation shaft of the compressor 9 and the main shaft of the inverter motor 41 are parallel to facilitate the belt connection. Or, due to the structural characteristics of the compressors 9 of different models, when the compressors 9 are installed, the rotating shafts of the compressors 9 may not be parallel, and then the main shaft of the inverter motor 41 may be parallel to the rotating shaft of the compressor 9 by adjusting the position of the inverter motor 41.

In order to prevent the supporting plate 51 from touching the ground, when the nut 58 drives the supporting plate 51 to move downward, the limiting block 52 can limit the supporting plate 51, and prevent the supporting plate 51 from moving downward.

Through setting up adjusting device 5, can adjust inverter motor 41's mounted position according to actual need to this kind of adjustment has not only included the adjustment of mounting height, has still included the adjustment of installation angle, makes inverter motor 41 can be in suitable mounted position all the time. In addition, the fine adjustment of the installation position of the variable frequency motor 41 can be realized through the adjusting device 5, and when the adjustment is performed, the installation position of the variable frequency motor 41 can be correspondingly adjusted only through the rotation of the screw rod 59, so that the adjustment is very convenient and fast. In addition, the test stand 100 can be adapted to test the compressors 9 by adjusting the adjusting device 5 for the compressors 9 of different models. And the tension of the belt can be adjusted to a certain degree by adjusting the position of the variable frequency motor 41.

The control device 6 is used for controlling the test conditions of the test stand 100, for example, the control device 6 may include a power main switch 61, a motor power supply switch 62, a touch control screen 63, an emergency stop switch 64, an operation time display table 65 and the like.

The above detailed description is only for the purpose of illustrating the preferred embodiments of the present invention, and not for the purpose of limiting the scope of the present invention, therefore, all equivalent technical changes that can be made by applying the present invention are included in the scope of the present invention.
