Description

Technical Field

[0001] This utility model relates to the field of friction pad testing technology, specifically a test device for monitoring the friction state of friction pads. Background Technology

[0002] In tests to monitor the friction state of friction pads, a commonly used test device clamps a steel wire rope with a fixture, and then makes the steel wire rope move back and forth, thus causing friction with the friction pad. This simulates the friction situation in actual use scenarios, thereby monitoring the friction state of the friction pad.

[0003] Existing monitoring devices generate a large amount of dust and debris during the friction process. This dust and debris are directly exposed to the air, which not only pollutes the experimental environment but also affects the health of the experimenters. At the same time, the heat generated by friction is quickly dissipated into the air, making it impossible to simulate the actual use scenario of the friction pad in the relatively enclosed environment inside the device. This results in the inability to accurately monitor the temperature of the friction pad during use, thus affecting the accuracy of the friction condition assessment of the friction pad.

[0004] The above problems arise primarily because the existing testing equipment lacks effective dust prevention and heat insulation structures. There are no dedicated components to collect and treat the dust and debris generated by friction, allowing the dust to spread. Simultaneously, the lack of insulation prevents the retention of heat generated by friction, leading to distorted temperature monitoring data that fails to accurately reflect the temperature changes of the friction pad under actual working conditions.

The wire rope abuts against the bottom pressure block, and the top of the upper pressure block is rotatably connected to a bolt. The bolt is threadedly assembled with the fixing component 23. By tightening the bolt, the upper pressure block and the lower pressure block are brought closer together, thereby clamping the wire rope.

[0035] According to the appendix Figure 1 , 3 As shown in Figures 4 and 5, further, it includes a body 1, on which a reciprocating motion component 2 is provided, and a dustproof and heat-insulating unit 3 is provided on one side of the top of the body 1.

[0038] In this embodiment, the liner is installed inside the insulation chamber 31 during the test. A guide dust extraction component 32 is located at the bottom inner part of the insulation chamber 31. When the liner rubs against the wire rope, generating debris, the air pump 327 is activated, generating suction through the elastic air supply pipe 326 and the conduit 322. The debris is guided into the conduit 322 by the guide bucket 321, filtered by the filter 324, and collected.
