Description

Technical Field

[0001] This utility model relates to the field of air cargo transportation technology, and in particular to a fireproof cover fire resistance performance testing rack for air cargo. Background Technology

[0002] In air cargo transportation, it is typically required that cargo be covered with a fireproof cover to reduce the risk of abnormal heating or fire. During the production and application verification of fireproof covers, performance tests simulating real cargo fire environments are necessary to evaluate key indicators such as flame retardancy, heat resistance, and fire spread suppression capabilities. In these simulation tests, the outer surface of the fireproof cover may exhibit fire characteristics such as localized high temperatures, smoke seepage, material discoloration, charring, or bulging. The accuracy of identifying these characteristics directly affects the reliability of the test results.

[0003] Currently, the detection of the fire condition of fireproof covers still mainly relies on manual methods, with ground operators visually observing the exterior of the fireproof covers or judging their heat absorption by touch. However, fireproof covers are usually directly covered onto simulated test cargo, and inspectors need to rely on handheld devices, temporary supports, or manual assistance to adjust the observation angle. The cargo is usually large, which increases the difficulty of operation during the inspection process, resulting in low inspection efficiency and a high risk of missed detections and deviations. Utility Model Content

[0004] The purpose of this application is to provide a fireproof performance testing frame for fireproof covers used in air cargo, so as to solve the problem of instability in the performance testing of fireproof covers by manual methods in the prior art.

[0005] To achieve this objective, the following technical solution is adopted in this application:

[0006] This application provides a fireproof cover fire resistance performance testing frame for air cargo, comprising a frame body, several mounting components, and several testing components, wherein:

[0007] The frame is equipped with a storage space, the shape of which is consistent with the appearance of the goods. The goods are placed in the storage space and the fireproof cover on the goods maintains a preset distance from the inside of the frame.

[0008] Several mounting components are evenly distributed on the frame.

The first end of the screw passes through the first waist-shaped hole and the mounting groove in sequence to be fixedly connected with the snap-fit ​​block in the mounting groove. The nut is screwed to the second end of the screw and abuts against the mounting plate.

[0015] Optionally, the mounting assembly includes two sets of first fixing components, with two first oblong holes arranged in parallel on the mounting plate, each first oblong hole corresponding to a set of first fixing components.

[0016] Optionally, the connecting assembly includes a connecting plate and two sets of second fixing components, wherein:

[0021] 2) By receiving temperature information through the camera component and taking pictures of locations exceeding the preset temperature, the location of high temperature anomalies is accurately recorded, the high temperature hazard points of the fireproof cover are automatically locked, and visual detection evidence is retained for subsequent analysis and evaluation, thereby further improving the accuracy and traceability of the detection results.

[0022] 3) By setting the support rod as a square tube structure, and evenly opening four mounting slots extending along the length direction on the outer circumference, it achieves orderly storage of wire harnesses, avoids wire harness tangling or damage, ensures the reliability of circuit connection, and keeps the frame tidy, making it easy to operate and maintain; on the other hand, it provides a lightweight frame that is easy to transport and disassemble.

[0023] 4) By using the snap-fit ​​block to fit the snap-fit ​​groove in the mounting slot of the support rod, the screw passes through the first waist-shaped hole of the mounting plate and is fixed to the snap-fit ​​block, realizing the adjustable fixation of the mounting component. This not only adapts to the testing requirements of different specifications of fireproof covers, but also makes the adjustment operation convenient. Attached Figure Description
