[0061] Example 2

[0062] refer to Fig.10 , improved on the basis of Example 1: a sliding rheostat 28 is fixed on the top of the test bench 1, which is electrically connected to the connector 43 to control the current provided to the power equipment. An L-shaped connecting tube 27 is fixed on the top of the U-shaped frame 26, which cooperates with the metal slider on the sliding rheostat 28 to control the resistance, thereby testing the operating conditions, temperature and vibration conditions of the power equipment under different currents.

[0063] Through the above specific implementation methods, the multifunctional comprehensive test platform for electric equipment can realize all-round detection of electric equipment, including temperature, vibration, noise, rotation speed and operating status under different currents, etc., and has high practicality and operability.

[0064] A method for using a multifunctional power equipment comprehensive test platform comprises the following steps:

[0065] S1. Place the electrical equipment to be tested on the rubber pad 42. The output shaft of the multi-stage cylinder 7 pushes the lifting plate 8 and the pressing plate 9 downward. With the cooperation of the guide rod 10 and the spring 11, the pressing plate 9 generates pressure on the electrical equipment and clamps it. At the same time, the insertion rod 12 is inserted into the insertion block 13, so that the insulating plate 2 and the lifting plate 8 form a whole. In addition, the lifting plate 8 synchronously drives the clamping plate 15 to move downward. Under the action of the inclined surface of the trapezoidal contact plate 17 and the tension of the first tension spring 16, one end of the trapezoidal contact plate 17 can complete the horizontal clamping and fixing of the electrical equipment.

[0066] S2, the connector 43 cooperates with the wire, the power equipment is powered on, and the temperature and vibration of the power equipment during operation can be tested through the temperature sensor 19 and the vibration sensor 20, which is convenient for the tester to analyze; in addition, the motor drives the turntable 24 to rotate, and the turntable 24 drives the L-shaped connecting tube 27 to move through the cooperation of the pin 25 and the moving groove 34. The L-shaped connecting tube 27 cooperates with the metal slider on the sliding rheostat 28 to control the size of the resistance, so that the power equipment can be tested under different currents. Its operating conditions and temperature and vibration conditions in this state;

[0067] S3. In addition, the motor speed can also be tested; in specific operation, when the clamping plate 15 and the trapezoidal contact plate 17 cooperate to clamp the motor horizontally, the rotating disk 22 cooperates with the motor output shaft, and the protrusion in the rotating disk 22 cooperates with the keyway on the motor output shaft. When the motor is running, the rotating disk 22 can be driven to rotate, and the speed detector 23 can be used to test the speed of the motor during operation. In addition, the decibel meter 18 can detect the noise generated when the motor is running, and the speed and noise of the motor under different currents can also be detected by the sliding rheostat 28;

[0068] S4. Since some power equipment is operated in a moving and bumpy state, the power equipment can also be tested in this state; specifically, tighten the bolt 32, insert the bolt 32 into the moving groove 34, and there will be no collision between the bottom end of the bolt 32 and the top end of the pin 25. At this time, the insulating plate 2 can be driven to move by the cooperation of the bolt 32, the moving groove 34 and the fixed plate 31 during the rotation of the turntable 24. The insulating plate 2 drives the lifting plate 8 and the rectangular block 6 to move through the plug block 13 and the plug rod 12. At this time, the power equipment can be tested accordingly in the moving state;

[0069] S5. In addition, when testing the electrical equipment in a bumpy state, the specific operation is to energize the electromagnet 40, and the magnetic attraction of the electromagnet 40 on the movable plate 37 is greater than the tension of the second tension spring 39. The movable plate 37 drives the second curved plate 41 to move toward the electromagnet 40, and the electromagnet 40 cooperates with the second curved plate 41. Therefore, when the fixed plate 31 drives the insulating plate 2 to move, the cooperation of the electromagnet 40 and the second curved plate 41 can make the insulating plate 2 vibrate with a certain amplitude, so that the relevant detection of the electrical equipment can be carried out in this bumpy state.

[0070] However, as is well known to those skilled in the art, the working principles and wiring methods of the sliding rheostat 28, electromagnet 40, speed detector 23, decibel meter 18, temperature sensor 19, vibration sensor 20 and multi-stage cylinder 7 are commonplace, and are all conventional means or common knowledge, and will not be elaborated here. Those skilled in the art can make any optional selections according to their needs or convenience.

[0071] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
