Description

Technical Field

[0001] This utility model relates to the field of rubber pad testing, and in particular to a testing device for the under-rail rubber pads of a track damper. Background Technology

[0002] Track dampers are specialized devices installed on track structures to reduce vibrations and noise generated during train operation, improve passenger comfort, and protect track structures from long-term vibration damage. They utilize elastic pads and damping principles to effectively absorb and disperse the energy generated during train operation, ensuring stable operation of the track and train.

[0003] Existing testing mechanisms for under-rail rubber pads in track dampers are specialized devices used to evaluate the performance of under-rail rubber pads in railway track systems. Their core function is to accurately test the mechanical properties, durability, and aging degree of the rubber pads to ensure track safety and damping effect. However, current rubber pads are usually placed on a pusher plate and then pushed onto a testing machine for gravity testing. Since the gravity head on the testing machine is located in the center, visual observation of the position of the pusher plate after it is pushed can easily cause deviation and misalignment from the gravity head. This results in some edges of the rubber pad not being subjected to gravity testing during the test, leading to incomplete test data. Utility Model Content

[0027] This utility model provides, for example Figure 1 - Figure 6 The device shown is a testing device for the under-rail rubber pads of a track damper. It includes a mounting base 1 and a testing component 21 mounted above the mounting base 1. The mounting base 1 serves as the basic support structure for the entire testing mechanism, providing mounting positions for other components and bearing various forces during the testing process.

[0029] An adsorption assembly 7 is installed at the bottom of the fixed plate 13. The adsorption assembly 7 is used to adsorb the rubber pad under the rail. The adsorption assembly 7 includes a vacuum generator 71 and a flexible suction cup 72. The vacuum generator 71 is installed on the mounting base 1. The vacuum generator 71 generates a vacuum environment to provide adsorption force for the flexible suction cup 72. The flexible suction cup 72 is installed on the vacuum generator 71. The top of the flexible suction cup 72 is flush with the fixed plate 13. The flexible suction cup 72 can fit tightly with the rubber pad under the rail. Under the action of the vacuum generator 71, the rubber pad is stably adsorbed, preventing the rubber pad from being misaligned during the phased test.

[0030] The mounting base 1 is provided with a first track body 15 and a second track body 16. The first track body 15 and the second track body 16 provide sliding tracks for the T-shaped track block 31 and the L-shaped track block 41, respectively, to ensure the stability of the movement of the first calibration rod 3 and the second calibration rod 4. The T-shaped track block 31 is slidably connected in the first track body 15 and is fixedly connected to the bottom of the first calibration rod 3. The L-shaped track block 41 is slidably connected in the second track body 16 and is fixedly connected to the bottom of the second calibration rod 4.

[0031] The first drive component 5 includes:

[0032] The first double-threaded screw 51 is rotatably connected to the mounting base 1. The first double-threaded screw 51 is threadedly connected to the T-shaped track block 31. By rotating itself, the T-shaped track block 31 slides within the first track body 15, thereby driving the first calibration rod 3 to move.

[0033] The first servo motor 52 is mounted on one side of the mounting base 1. One end of the first double-threaded screw 51 is fixedly connected to the output end of the first servo motor 52. The first servo motor 52 provides power for the rotation of the first double-threaded screw 51.

[0034] The second drive component 6 includes:

[0035] The second double-threaded screw 61 is rotatably connected to the mounting base 1. The second double-threaded screw 61 is threadedly connected to the L-shaped track block 41. The second double-threaded screw 61 drives the L-shaped track block 41 to slide within the second track body 16 through its own rotation, thereby driving the second calibration rod 4 to move.

[0036] The second servo motor 62 is mounted on the back of the mounting base 1, and the second double-threaded screw 61 is fixedly connected to the output end of the second servo motor 62. The second servo motor 62 provides power for the rotation of the second double-threaded screw 61.

[0037] A guide rod 11 and an electric push rod 12 are fixedly connected to the mounting base 1. A gantry frame 2 is fixedly connected to the output end of the electric push rod 12. The guide rod 11 is slidably connected inside the gantry frame 2. The detection component 21 is installed on the gantry frame 2. The guide rod 11 provides guidance for the movement of the gantry frame 2, ensuring the straightness of the movement of the gantry frame 2. The electric push rod 12 controls the up and down movement of the gantry frame 2 through its own extension and retraction, thereby adjusting the height of the detection component 21.

[0039] The detection component 21 includes a hydraulic rod and a gravity head. The hydraulic rod is mounted on the gantry 2, and the gravity head is fixedly connected to the bottom of the output end of the hydraulic rod.

[0040] Example 1: The mounting base 1 serves as a basic support, on which a fixing plate 13 is fixed for placing the rubber pad under the rail. To ensure that the rubber pad is accurately positioned at the center of the fixing plate 13 and below the gravity head, the mounting base 1 is equipped with a first calibration rod 3 and a second calibration rod 4. In the first drive assembly 5, the first servo motor 52 drives the first double-threaded screw 51 to rotate, and the first double-threaded screw 51 drives the T-shaped track block 31, which is threadedly connected to it, to slide within the first track body 15, thereby moving the first calibration rod 3. Similarly, in the second drive assembly 6, the second servo motor 62 drives the second double-threaded screw 61 to rotate, driving the L-shaped track block 41 to slide within the second track body 16, thereby moving the second calibration rod 4. This facilitates the position calibration of the rubber pad. After each calibration, the first drive assembly 5 and the second drive assembly 6 move the first calibration rod 3 and the second calibration rod 4 to the outermost position. This is to facilitate the collection of the tested rubber pad and to calibrate the position of the first calibration rod 3 and the second calibration rod 4. Meanwhile, the bottom of the fixed plate 13 is equipped with an adsorption component 7, and the vacuum generator 71 generates a vacuum environment, so that the flexible suction cup 72 fits tightly against the rubber pad and is firmly adsorbed, preventing it from being misaligned during the stage test and ensuring the comprehensiveness of the test.

[0041] Example 2: In this testing mechanism, a guide rod 11 and an electric push rod 12 are fixed on the mounting base 1. The output end of the electric push rod 12 is connected to the gantry 2. The guide rod 11 is slidably connected inside the gantry 2 to guide the movement of the gantry 2 and ensure its straightness. The testing component 21 is installed on the gantry 2. The electric push rod 12 controls the gantry 2 to move up and down by telescopic control, thereby adjusting the height of the testing component 21. During testing, the position of the rubber pad is first adjusted and secured by the first drive component 5 and the second drive component 6. Then, the electric push rod 12 is activated to lower the testing component 21 to a suitable position. The hydraulic rod controls the gravity head to press down on the rubber pad to perform gravity testing, simulating actual force to obtain performance data. All components work together to ensure accurate and reliable testing.
