Description

Technical Field

[0001] The utility model relates to the technical field of safety rope performance testing, in particular to a device for testing the bearing capacity of a safety rope in a high-temperature environment. Background Art

[0002] The safety rope is woven from synthetic fibers. It is an auxiliary rope used to connect to a safety belt and has a double protection function to ensure safety. It is usually used for aerial operations such as construction, installation, and maintenance. It is suitable for field electricians, construction workers, telecommunications workers, wire maintenance and other types of work, playing an important protective role. Most synthetic fibers such as nylon and polyester will gradually lose their strength and elasticity at high temperatures. Long-term exposure to high temperature environments or sudden high temperatures may cause the fibers to soften, melt or become brittle, thereby greatly reducing the load-bearing capacity and tensile strength of the safety rope. The load-bearing capacity of the safety rope directly affects the life safety of the user. Usually, when testing the load-bearing capacity of the safety rope, the test environment is at room temperature, and it is impossible to test the load-bearing capacity under different high-temperature environments. Therefore, a safety rope high-temperature environment load-bearing capacity test device is provided. Utility Model Content
