Description

Technical Field

[0001] The invention relates to the technical field of mechanical equipment, and in particular to a device for detecting the installation stability of mechanical equipment. Background Art

[0002] Motor is a kind of mechanical equipment. Motor, whose full name is electric motor, is a kind of equipment that converts electrical energy into mechanical energy. It plays a core driving role in mechanical equipment. Motor is usually composed of stator, rotor, end cover, bearing and other parts. The stator provides magnetic field, and the rotor rotates under force in the magnetic field, thereby outputting mechanical energy. Motor is widely used in various mechanical equipment, such as machine tools, fans, pumps, etc. in industrial production, electric vehicles and rail transportation in transportation, and washing machines, air conditioners, refrigerators, etc. in household appliances. Different types of motors have different characteristics and applicable scopes. For example, DC motors have good speed regulation performance, AC asynchronous motors have simple structure and reliable operation, and synchronous motors are suitable for high-precision driving occasions. The performance of motors directly affects the operating efficiency, reliability and stability of mechanical equipment. With the continuous advancement of science and technology, the technology of motors is also constantly innovating and developing, moving towards high efficiency, energy saving, miniaturization and intelligence.

[0003] The Chinese patent with the announcement number "CN217637905U" discloses a vibration detection device based on electromechanical equipment in coal mines. It is based on the vibration detection device for electromechanical equipment in coal mines, relates to the technical field of detection devices, solves the problem that the existing vibration detection device has a single vibration direction and can only detect and experiment the vibration resistance of the parts of the electromechanical equipment through the vibration force in the vertical direction, and the detection data is inaccurate. The device includes a drive block, which is plugged into the inside of the drive disk. When the device detects the vibration resistance of the parts of the mechanical equipment, the horizontal square vibration force and the vertical vibration force can be applied to the parts. The test is comprehensive and the results are accurate. At the same time, the vibration amplitude of the device in the horizontal direction can be freely adjusted, so that it can adapt to the vibration resistance performance detection of parts of different types of electromechanical equipment, and it is flexible and convenient to use;

[0004] During actual use, although the above-mentioned device has certain vibration detection functions, it mainly relies on a swing motor to drive the product to slide back and forth on its top to achieve detection. However, in the specific application process, this method has many limitations. First, it is impossible to flexibly adjust the intensity of the vibration impact, so that the test results may not accurately reflect the actual situation of the motor mechanical equipment under different vibration intensities. Secondly, it cannot achieve 360-degree angle reversal simulation detection, which leads to the inability to fully simulate the seismic impact resistance of the motor mechanical equipment under different states during specific use. Overall, it has certain limitations during the detection period and cannot further accurately detect the stability of the motor installation. It can be seen that the device has certain defects and deficiencies in the application process, and it is urgently needed to be improved and optimized to improve its detection accuracy and comprehensiveness, and better meet the actual needs of vibration detection of motor mechanical equipment.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] First, in the present invention, a lifting mechanism is provided to improve the performance of the device. Starting the first motor can drive the winding roller to rotate and rewind the lifting rope, thereby driving the lifting arm, the clamping mechanism and the motor to be tested to move upward. During the upward movement, the transmission gear is meshed with the transmission rack to drive the mounting seat to rotate, so that the motor to be tested is in a rotating swinging state. After being lifted to the top, the first motor reverses to loosen the lifting rope, and the motor to be tested moves downward.

[0019] Secondly, in the present invention, by setting a bearing mechanism, the device performs well in application.

Then the first motor is started and re-hoisted to hit, which is in a high-intensity reciprocating vibration state. During vibration detection, the weighing sensor detects the impact force in real time, which is convenient for data collection. It is widely used and has strong vibration simulation performance. It can better detect the stability of motor installation and provide strong support for motor quality detection and performance evaluation.

[0020] Thirdly, in the present invention, a load-bearing adjustment mechanism is provided to make the device more flexible and adjustable. When reducing the free-falling weight, the limit arm is pulled up to make the limit pressure plate move up and away from the load-bearing weight plate, and the weight can be removed. After loosening the limit arm, the telescopic spring resets and clamps the top weight. The same operation is performed when adding weights. By adjusting the number of load-bearing weight plates, the weight can be flexibly adjusted, so that the impact simulation test during the test of the motor to be tested can be adjusted, the installation stability of the mechanical equipment can be better tested, and the weight adjustment requirements of different testing needs can be met.

[0021] Fourthly, in the present invention, a clamping mechanism is provided to make the device more efficient and practical in use. The lifting mechanism lifts the clamping mechanism, and the transmission gear engages with the transmission rack to make it reverse upward. The motor to be tested is placed between the mounting frames inside the mounting seat, and the second motor is started to drive the lead screw to drive the slider to slide in the strip groove body. Since the threads at both ends of the lead screw have opposite rotation directions, the clamping frame can be driven to move. The conical clamping frame cooperates with the extended clamping plate to cover both ends of motors of different sizes, and the output shaft can be inserted into the reserved circular groove for stable clamping. The overall adaptability is strong, and it can be flexibly applied to a variety of motor installation stability simulation tests, thereby improving the flexibility and adaptability of the device and providing a reliable solution for different types of motor detection.

[0038] The working principle of the present invention is: by setting up the lifting mechanism 5, the device can show excellent performance during use. Specifically, by starting the first motor 52, the first motor 52 can drive the winding roller 53 to rotate. When the winding roller 53 rotates, the lifting rope 54 will be wound up. The winding of the lifting rope 54 will drive the lifting arm 61 to move upward. As the lifting arm 61 moves upward, the clamping mechanism 7 will also move upward. The upward movement of the clamping mechanism 7 will drive the motor 4 to be tested to move upward. In the process of moving upward, the transmission gear 76 will mesh with the transmission rack 77 for transmission. At this time, the transmission gear 76 can drive the connecting shaft 71 at the bottom of the lifting arm 61 to drive the mounting seat 72 to rotate. The rotation of the mounting seat 72 It can drive the motor 4 to be tested clamped inside to rotate. As the motor 4 to be tested rotates, the motor 4 to be tested can be in a rotating swinging state. When the lifting rope 54 lifts the motor 4 to be tested to the top, the first motor 52 is started to reverse. At this time, the winding roller 53 can loosen the lifting rope 54, so that the motor 4 to be tested moves downward. At this time, the transmission gear 76 and the transmission rack 77 are driven again to cause the motor 4 to be tested to rotate in the opposite direction, and then cause the motor 4 to be tested to swing toward the other side. It can be seen that the device as a whole can flexibly simulate the forward and reverse swings of the motor 4 to be tested, which greatly improves the overall detection effect of the device and provides a more comprehensive and accurate means for detecting the stability of motor installation.

[0039] By setting the bearing mechanism 2, the device performs well during application. When the motor 4 to be tested moves down, the motor 4 to be tested can directly hit the bevel gear 26 with the top of the weighing sensor 23. The bevel gear 26 contacts the shell of the motor 4 to be tested, so as to simulate the collision test. If a high vibration test is required, the receiving frame 22 inside the square groove 21 can be moved to the bottom of the motor 4 to be tested. At this time, the motor 4 to be tested hits the top of the bearing plate 25. The bottom of the bearing plate 25 is connected to the buffer spring 24. The bearing plate 25 and the buffer spring 24 can be retracted and buffered. Activity, at this time, the motor 4 to be tested on the top of the load-bearing plate 25 can instantly generate a high impact from a high vibration state and vibrate again, and then, the first motor 52 is started to lift the motor 4 to be tested again and impact it, so that the whole motor can be in a high-intensity reciprocating vibration state. At the same time, during the vibration detection process, the weighing sensor 23 can detect the impact force in real time, which is convenient for collecting vibration test data. The overall application period is more extensive, and the vibration simulation performance is stronger. During use, the stability of the motor installation can be better detected, which provides strong support for the quality detection and performance evaluation of the motor.

[0040] By setting up the load-adjusting mechanism 6, the device has higher flexibility and adjustability during use. When it is necessary to reduce the gravity of the free fall, the limit arm 646 can be pulled up. At this time, the limit arm 646 pulls the telescopic spring 645 and drives the limit pressure plate 647 to move up at the same time. The limit pressure plate 647 moves up to separate from the weight weight disk 643. At this time, the weight weight disk 643 can be removed from the outer surface of the limit rod 641. After loosening the limit arm 646, the telescopic spring 645 is reset to push the limit pressure plate 647 to fit the weight weight disk 643 at the top. The weight plate 643 is clamped and fixed, and if it is necessary to increase the weight plate 643, the limit arm 646 can be pulled upward to cause the limit pressure plate 647 to be separated from the top of the weight plate 643. At this time, the weight plate 643 is placed on the outer surface of the limit rod 641 to complete the increase of the weight plate 643. By adjusting the number of weight plate 643, the weight of the weight adjustment mechanism 6 can be flexibly adjusted, so that the impact simulation test during the test of the motor 4 to be tested can be adjusted, and the overall installation stability of the mechanical equipment can be better tested to meet the weight adjustment requirements under different testing needs.

[0041] By setting the clamping mechanism 7, the device is made more efficient and practical during use. The lifting mechanism 5 can be started to lift the clamping mechanism 7. Due to the meshing of the transmission gear 76 and the transmission rack 77, the clamping mechanism 7 can be reversed upward. At this time, the motor 4 to be tested is placed between the inner sides of the two mounting frames 51 inside the mounting seat 72. By starting the second motor 742 to run, the second motor 742 can drive the screw rod 741 to drive the slider 743 to slide inside the strip groove body 73. Since the threads at both ends of the screw rod 741 are rotated in opposite directions, the slider 743 is driven by the screw rod 741 to slide back and forth inside the strip groove body 73. At this time, the slider 74 can be driven 3 drives the clamping frame 752 to move with each other, and the conical clamping frame 752 cooperates with the extended clamping plate 754 to be sleeved on both ends of the motor 4 to be tested.
