The steel container pressure test device according to claim 7, characterized in that: The top of the medium tank (201) is provided with an injection port (202), the bottom side of the output pipe (206) is provided with a pressure sensor (207), and the pressure sensor (207) is provided on the inner side of the compression plate (303).

9. A test method for a steel container pressure test device, characterized in that: The steel container pressure test device according to claim 8 is used, comprising the following steps: S1. A steel container to be subjected to a pressure test is placed on the input end surface of the conveyor belt (603). The motor (605) is then driven to rotate the conveyor shaft (602), thereby driving the conveyor belt (603) to move and transport the steel container to the position of the positioning mechanism (5). During the transportation process, the anti-slip strip (604) provides anti-slip treatment to ensure stable transportation. S2. When the steel container is transported between the two positioning mechanisms (5), the positioning frame (503) is synchronously pushed to move toward each other by two sets of electric telescopic rods (502). During the movement, the steel container (4) is scooped up by the shovel plate (504). At the same time, the sliding member (507) is slidably installed through the sliding groove (506). The bidirectional hydraulic telescopic rod (511) is connected to the sliding member (507) in conjunction with the connecting member (510). The bidirectional hydraulic telescopic rod (511) is used for telescopic adjustment control, thereby driving the sliding member (507) and the clamping member (508) to open and close. The inner side of the sliding member (507) is movably connected to the clamping member (508) and is clamped in conjunction with the clamping pad (509), which is conducive to positioning the steel container (4); S3. The pneumatic push rod (514) is supported by the support plate (512), and the clamping member (508) is further clamped on the steel container (4) by adjusting the pneumatic push rod (514) to be extended and adjusted, thereby improving the clamping stability, ensuring stable clamping of the steel container (4) during the test, and achieving precise positioning; S4. After positioning is completed, the pressing plate (303) is pushed downward by the pneumatic lifting column (302), so that the pressing plate (303) is tightly sealed on the steel container (4). The sealing ring (304) is distributed in different calibers, and the sealing groove (305) facilitates the compression and sealing of steel containers (4) of different calibers; S5. After compaction, the medium liquid loaded in the medium tank (201) is extracted through the delivery pump (204) in cooperation with the elbow (203), and then the liquid medium is delivered to the output pipe (206) through the delivery pump (204) in cooperation with the hose (205). The liquid medium is input into the interior of the steel container (4) through the output pipe (206) to form pressure. A pressure sensor (207) is provided on the side of the output pipe (206) to provide pressure detection, thereby facilitating the realization of the pressure test function. After the test is completed, the output pipe (206) is connected to the extension pipe to withdraw the medium liquid in the steel container (4); S6. After the pressure test is completed, the electric telescopic rod (502) is retracted, and the bidirectional hydraulic telescopic rod (511) drives the clamping member (508) to expand, and the steel container (4) is separated. This facilitates the conveying shaft (602) driven by the driving motor (605) to drive the conveyor belt (603) for conveying, and facilitates the output of the tested steel container (4), thereby realizing automated batch testing.
