Description

Technical Field

[0001] The utility model belongs to the field of speed reducer detection, in particular to a diversified test platform. Background Art

[0002] Free-fall winches are mainly used in equipment such as tamping machines, multi-functional crawler cranes, marine engineering machinery, and double-wheel milling machines to provide lifting and lowering functions. Compared with general winches, this type of product has high efficiency, can meet the needs of rapid lowering functions, is highly safe, and does not require manual mechanical unhooking or hooking throughout the entire process. Therefore, this product has very high reliability requirements. In order to meet the stringent factory test requirements, the reducer and wet brake system of the free-fall winch need to be subjected to performance tests and fatigue tests to ensure that the product runs smoothly in various application scenarios and harsh working conditions.

[0003] In the existing reducer test bench, the load motor can provide the necessary load conditions for the test system to simulate the real working environment. However, in certain test scenarios, if the maximum allowable speeds of the load motor and the drive motor are inconsistent, the rated speed of the load motor will not only fail to meet the target working condition requirements, but also cause irreversible damage to the load motor. Therefore, adopting a more flexible speed control strategy and strengthening motor protection measures have become an urgent need to improve test efficiency and accuracy. Utility Model Content

DETAILED DESCRIPTION

[0028] In the following description, a large number of specific details are given to provide a more thorough understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the utility model, some technical features known in the art are not described.

[0029] See attached Figures 1 to 4A diversified test platform is built on a stable working surface, which is fixed to the foundation by a pressure plate, increasing the impact resistance and reliability of the test process. The working surface integrates a driving component, a loading component, a connecting transmission component, a first wet brake 8 and a second wet brake 9. According to the test input requirements, the above modules can be simplified and arranged to meet the test verification requirements of different product stages.

[0030] The driving assembly includes a driving motor 16, and a test reducer 11 connected to the driving motor 16 for providing the speed required for the test. The loading assembly includes a load motor 1, a loading reducer 6 connected to the load motor 1, and a speed regulating structure 13 arranged between the load motor 1 and the loading reducer 6; it is used to simulate the actual working load, and through the adjustable chain 5 transmission system, ensure the precise control of the loading conditions. The connecting transmission assembly includes a first sprocket 4 connected to the output end of the test reducer 11, a second sprocket 12 connected to the output end of the loading reducer 6, and a chain 5 installed between the first sprocket 4 and the second sprocket 12. When the maximum allowable speeds of the load motor 1 and the driving motor 16 are inconsistent during the test, the speed regulating structure 13 can be optionally configured to adjust the output speed of the driving motor 16, and the speed is transmitted to the loading reducer 6 through the connecting transmission mechanism, covering the test range of the load motor 1, and is suitable for the test of reducer products of different speed categories.

[0031] In a further embodiment, the drive motor 16 outputs the rotation speed to the input end of the test reducer 11 through the first coupling 2 and / or the first universal joint 3; the load motor 1 transmits the torque to the loading reducer 6 through the second coupling 15 and / or the second universal joint 14 and the speed regulating structure 13. The axial spacing between the drive motor 16 and the load motor 1 is adjusted through the first coupling 2 and the first universal joint 3, the second coupling 15 and the second universal joint 14, so as to realize the efficient power transmission from the drive motor 16 and the load motor 1 to the respective reducers, while maintaining the adaptability to different working conditions, and can dynamically fine-tune the axial orientation of each connecting component, thereby improving the flexibility function of the test platform.

[0032] In a further embodiment, the chain 5 is detachably mounted on the first sprocket 4 and the second sprocket 12, and is dynamically adjusted by increasing or decreasing the length of the chain 5, and the radial orientation of each connecting component is dynamically fine-tuned to improve the flexibility of the test platform. The first sprocket 4 and the second sprocket 12 both have sprockets with two or more rows of teeth, and the number of chains 5 arranged side by side is increased or decreased according to the load torque, thereby dynamically adjusting the reliability redundancy of the test load.

[0033] That is to say, the lateral spacing between the drive motor 16 and the load motor 1 can be adjusted by increasing or decreasing the number of chains 5, and the axial spacing between the drive motor 16 and the load motor 1 can be adjusted by the universal joint and the coupling, and both the drive motor 16 and the load motor 1 are modular structures. According to the difference in test requirements of the loading reducer 6 and the test reducer 11, two installation test modes of parallel and series connection of the loading reducer 6 and the test reducer 11 are realized.

[0034] In a further embodiment, the test reducer 11 is connected to the first wet brake 8 by a spline, and the working surface is fixedly mounted with a first flange 7 through a bracket, and the first flange 7 is connected to the first wet brake 8 by a bearing. The first wet brake 8 locks the first and second internal gear rings of the test reducer 11 under the action of spring force and friction pair components. The loading reducer 6 is connected to the second wet brake 9 by a spline, and the working surface is fixedly mounted with a second flange 10 through a bracket; the second flange 10 is connected to the second wet brake 9 through a bearing. The first wet brake 8 locks the first and second internal gear rings of the test reducer 11 under the action of spring force and friction pair components. The first and second internal gear rings of the loading reducer 6 and the test reducer 11 are locked by the first wet brake 8 and the second wet brake 9 to ensure the test loading of the reducer, which is suitable for the test of multi-stage transmission reducer mechanism.

[0035] The test platform can be used for both the reducer performance test and the wet brake performance test. After completing the reducer performance test, the wet brake performance test can be completed by disassembling the chain 5, and the load motor 1 and the drive motor 16 are started to simultaneously realize the no-load running-in test of the first wet brake 8 and the second wet brake 9, thereby improving the test efficiency and saving the tedious assembly and disassembly time.

[0036] In a further embodiment, the speed regulating structure 13 includes a fixed bracket 131 fixedly mounted on the working surface, a gearbox 132 arranged on the fixed bracket 131, and two connecting flanges 133 arranged at both ends of the gearbox 132, respectively used to connect the load motor 1 and the loading reducer 6. The gearbox 132 is a key component of the speed regulating structure 13, and its interior usually contains a gear set or other transmission mechanism (such as planetary gears, worm gears, etc.), the purpose of which is to achieve a significant increase in the external output speed through the conversion of the gear ratio without increasing the speed of the load motor 1, thereby meeting the requirements of the test platform for high-speed test conditions.

[0037] In a further embodiment, the test platform is also provided with a data acquisition component. The data acquisition component includes: a magnetic vibration sensor 17 installed at the vibration-prone point of the loading reducer 6 and / or the test reducer 11, a magnetic temperature sensor 18 installed at the bearing position of the loading reducer 6 and / or the test reducer 11, a magnetic Bluetooth temperature sensor 19 installed at the bearing position of the loading reducer 6 and / or the test reducer 11, a noise sensor 20 installed at a specified distance position of the working surface for noise measurement, a torque sensor 21 installed at the output shaft position of the load motor 1 or the drive motor 16, a data acquisition control module 22 integrated in the industrial computer outside the test bench, and a data display module 23 installed in a workroom with safety protection and noise reduction protection. The magnetic vibration sensor 17, the magnetic temperature sensor 18, the magnetic Bluetooth temperature sensor 19, and the noise sensor 20 dynamically collect the temperature, noise and vibration parameters of the key monitoring points during the load test. By setting the threshold of each sensor parameter, the test bench process is monitored through the data acquisition control module 22. When the temperature / vibration / noise threshold exceeds the limit alarm, visualization is achieved through the data display module 23, and the system platform automatically responds to the emergency stop mode, and the process safety is controllable.

[0038] In summary, the experimental platform of this embodiment can realize the performance test of high-torque and high-speed reducers and wet brakes. The test platform is composed of various modular structures and can be flexibly combined according to the test requirements of different products. The test platform can improve and optimize the test bench through the gearbox 132 structure according to the differences in test requirements, which can not only make up for the speed difference at the load end of the reducer, but also increase the speed of 2 sets or more wet brake performance test benches. Through the flexible sensing channel, the data display is closed-type monitoring, which realizes process data monitoring and early warning at a safe distance, and improves the safety and reliability of the test.

[0039] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations.
