Problems solved by technology
[0003] At present, the fire test furnaces are all fixed one-piece furnace bodies. When installing the test components, hoisting equipment is required to install the components into the furnace chamber from the top to the bottom of the furnace. This installation method makes the positioning of the test components difficult, and the installation process It is cumbersome and requires high requirements for operators and hoisting equipment; at the same time, this installation method makes it difficult to fix the test components stably, resulting in poor test data accuracy

The invention relates to the field of testing of mechanical parts, in particular to a high-temperature-resistant test device for a bridge inhaul cable and a use method of the high-temperature-resistant test device. The high-temperature-resistant test device for the bridge inhaul cable comprises a high-temperature furnace (1) and a reaction frame (2), and is characterized by further comprising a test cable (3), supporting feet (4), a jack (5), a locking nut (6), a tensioning screw rod (7) and a thermocouple (8), an anchorage device (32) at the anchoring end of the test cable (3) is anchored to the reaction frame (2), and the anchorage device (32) at the tensioning end of the test cable (3) is connected with the tensioning screw rod (7); the jack (5) is sleeved on the tensioning screw rod (7); and the thermocouple (8) is arranged on the test cable (3). The use method of the high-temperature-resistant test device for the bridge inhaul cable is characterized by comprising the following steps of: (1) threading the cable and setting a thermocouple; (2) connecting the supporting feet and the jack; (3) carrying out tensioning; (4) performing high-temperature testing. The device is simple in structure, convenient to implement, accurate in testing and low in cost.
Description
technical field [0001] The invention relates to the testing field of mechanical parts, in particular to a high-temperature-resistant test device for bridge cables and a method for using the same. Background technique [0002] With the increasing number of fires in bridges and buildings, people are paying more and more attention to the performance changes of cables under fire and the resulting hazards. For bridges and building structure cables, fire is more of a threat than disasters such as wind and earthquakes. This threat is mainly reflected in the impact of high temperature on the structure, that is, the high temperature causes the temperature internal force of the structure and the decrease of the strength and stiffness of the material of the mechanism. The ultimate time is an important problem to be solved in the fire resistance research of bridges and building cables. Using the fire test furnace to simulate the actual fire to test the fire resistance of bridges and b...
