Description

Technical Field

[0001] This utility model relates to the field of gas cylinder strength testing, and in particular to a composite material gas cylinder strength testing device. Background Technology

[0002] Gas cylinders, as natural gas storage and transportation equipment, are usually made of glass fiber or carbon fiber wrapped around the outer surface of a steel inner liner. The fiber layer generally has to bear more than half of the internal pressure load, and the outer fiber layer is easily damaged by collisions and scratches.

[0003] Chinese Patent Publication No. CN217059664U discloses a strength testing device for power composite materials, including a base plate, support rods, a placement platform, a first support frame, a hammer, a sliding rod, and elastic elements. Support rods are connected to the left and right sides of the top of the base plate, and the placement platform is connected to the upper part of the two support rods. The first support frame is connected to the left rear side of the top of the base plate. However, the existing device still has some shortcomings. Composite material cylinders are inevitably subjected to low-speed impacts from foreign objects during manufacturing, storage, transportation, and use. Therefore, during the production process, composite material cylinders are repeatedly subjected to drop tests, and the impact strength of the composite material cylinders is judged based on the experimental data. To address this issue, we propose a strength testing device for composite material cylinders. Utility Model Content

[0006] In a further embodiment, the inner wall of the support frame has two sliding grooves, and the outer surface of the lifting block is equipped with two sliders, each of the sliding grooves being adapted to the slider.

[0007] In a further embodiment, the protective component includes a protective fence and an impact pad, both of which are located on the upper surface of the support plate, and a protective door is installed on the front of the protective fence.

[0008] Compared with the prior art, the beneficial effects of this utility model are: This utility model discloses a composite material gas cylinder strength testing device. Two electric push rods in the clamping assembly push two clamping blocks to clamp the gas cylinder to be tested. A lifting assembly raises the clamped gas cylinder to a suitable height, allowing it to fall freely. By observing the cylinder's appearance, its impact resistance can be determined. Furthermore, a rotating assembly rotates the gas cylinder, allowing it to fall at different angles, ensuring the accuracy of the experiment.
