Description

Technical Field

[0001] The present application relates to the field of train rubber vibration isolators, and in particular to a hardness detection device for train rubber vibration isolators. Background Art

[0002] Rubber isolators are made of rubber and can be used in both compression and shear states. Their biggest advantage is that they have sufficient internal damping and are suitable for situations where static displacement is small but dynamic displacement is short but large. They can also be made into various shapes to meet space requirements. Their disadvantages are that they will age and produce creep. They are mainly used to isolate high-frequency vibrations and are widely used in vibration isolation of trains.

[0003] The structure of the product can refer to a train rubber isolator hardness detection device disclosed in Chinese patent document 202211523154.X, including a top plate, the top of the top plate is penetrated with two groups of first telescopic holes distributed on the left and right, the top of the top plate is fixedly connected to a limit frame, the top of the limit frame is penetrated with two groups of second telescopic holes distributed on the left and right, the two groups of the second telescopic holes are distributed directly above the two groups of first telescopic holes, and the specifications of the limit frame are the same as those of the second telescopic holes. The output shaft of the stepper motor drives the driving gear to rotate, so that the two groups of lifting gears engaged therewith rotate, so that the first threaded hole rotates, and under the action of the threaded thrust of the threaded lifting rod, the two groups of threaded lifting rods are driven to move upward, thereby driving the lifting platform to move upward, so that the limit pull rod and the lifting block move synchronously, so that the isolator is pulled, and the mechanical strength of the isolator is judged by the anti-pulling level of the isolator.

[0004] However, in this patent, when the hardness of the train rubber vibration isolators is tested, the train rubber vibration isolators are placed on a workbench one by one and then tested, which reduces the work efficiency.

[0005] A train rubber isolator hardness detection device is now provided. Summary of the invention
