Fire resistance test platform for large rotator

Abstract

The invention provides a testing platform for the fire resistance of a large revolving body. The testing platform comprises a simulated heating device for providing a real heating environment, a tested part pose adjusting platform and a control system, wherein the flame size and the heating temperature of the simulated heating device are controllable and adjustable; the tested part pose adjusting platform can provide a mounting and locating interface of a tested part, can realize five-freedom-degree rotation and movement in space, can realize controllable and adjustable relative space position and can simulate the pose of the tested part in a temperature field; and the control system acquires temperature and the pose signals of the tested part in real time and controls the relative sensitivity parameters in real time. The testing platform can really simulate the fire scene with high efficiency, the temperature distribution of the tested part is controllable and adjustable, the installation and location operations are very convenient, and the universality is strong, so that reference is provided for practical application of a fire-resistant revolving body workpiece; the whole mechanical system has a skillful structure, has high integration degree, is very convenient to install and locate, and has the advantages of openness, flexibility design, high precision and the like.

Description

technical field [0001] The invention relates to a large-scale revolving body fire resistance testing platform. Background technique [0002] Since the "9.11" incident in the United States, countries around the world have paid more attention to the fire prevention of steel structures, especially in the fields of ships and aircraft. Once a fire occurs, if the material itself is not fireproof or even combustible, it will only bring greater fire hazard, so the fire-resistant and fire-resistant properties of the material itself have received great attention, such as: fire-resistant coatings for steel structures should have good heat insulation when exposed to fire (thick fire-resistant coatings), thermal insulation and fire-proof after heating (thin) Fireproof coating); Inorganic composite fireproof boards still have low thermal conductivity and slow down the heat conduction rate when exposed to fire; Inorganic fibers not only have good adhesion, but also increase slowly in therm...

Problems solved by technology

For the high-temperature compressive strength and refractoriness test of large-scale rotating parts such as large cylinders and cones, the large-scale rotating parts are generally scaled in equal proportions, placed in a high-temperature furnace or hoisted on a high-temperature furnace mouth, and tested. This test method Not only is it cumbersome and expensive, but also the accuracy is very poor. It is difficult to control the sensitive parameters in the whole test process, and it is impossible to truly simulate the fire resistance performance of materials under actual fire conditions.
