Description

Technical Field

[0001] The utility model relates to the technical field of fire extinguisher sealing detection, in particular to a supporting device of a fire extinguisher cylinder sealing detection machine. Background Art

[0002] Fire extinguishers are one of the most common fire-fighting equipment. During their production process, sealing testing of fire extinguishers is an important step, which is also called cylinder sealing testing.

[0003] Nowadays, the sealing of steel cylinders is mainly tested through the gas-liquid observation method, that is, the steel cylinder is placed in a test pool, and the inside of the cylinder is inflated to observe whether there are bubbles, so as to judge whether the cylinder is qualified.

[0004] At present, the sealing test machine can only test a single cylinder, so the efficiency is not high. If multiple cylinders need to be tested at the same time, multiple fixtures need to be installed, and each fixture is independent of each other, which is very cumbersome to use.

[0005] Secondly, since the steel cylinder is formed by welding, there will be welding impurities on the surface. During the sealing test, these impurities will affect the accuracy of the test.

[0006] In summary, it is necessary to make necessary improvements to the existing sealing detection machine. Utility Model Content

[0073] It should be noted that: when fixing the steel cylinder, the rotation of the second body can adjust the steel cylinder so that the steel cylinder can be better fixed by the clamping plate.

[0074] Example 2 is different from Example 1 in that:

[0075] like Figure 4-6 As shown, in this embodiment: a supporting device is also included, the supporting device corresponds to the clamping area, and the supporting device includes:

[0079] The pool body 10 is provided with a plurality of cleaning structures corresponding to the support shafts 50 . The cleaning structures can move around the cylinder and clean the outer wall of the cylinder when the support shafts 50 rotate.

[0080] In this embodiment: each cleaning structure includes:

[0081] A driving plate 60 is mounted on the support shaft 50;

[0082] A plurality of cleaning shafts 61 are rotatably mounted on the drive disk 60 and are equidistantly spaced about the support shaft 50;

[0083] The cleaning brush 62 is disposed on the cleaning shaft 61 .

[0084] In this embodiment, the driving disk 60 is provided with a plurality of support openings 60a corresponding to the cleaning shafts 61, and a circumferentially extending limiting groove 60b is provided on the inner wall of the support opening 60a, wherein the cleaning shaft 61 includes:

[0086] The shaft body 612 is mounted on the shaft disc 610 and has the cleaning brush 62;

[0087] Among them, the shaft body 612 is arranged coaxially with the shaft disc 610, and one end passes through the shaft disc 610 and is installed with a driven gear 613. A gear ring 614 is fixedly connected to the bottom inner wall of the pool body 10 and is arranged coaxially with the driving disc 60, and each driven gear 613 is engaged with the gear ring 614.

[0088] In this embodiment: the support shaft 50 includes:

[0089] The first shaft 501 is connected to the transmission shaft 52 and fixedly connected to the driving disc 60;

[0090] The second shaft 502 is coaxial with the first shaft 501;

[0091] Wherein, a one-way rotation structure is provided at the joint between the first shaft 501 and the second shaft 502 .

[0092] In this embodiment: the one-way rotation structure includes:

[0093] The one-way shaft 70 is integrally formed on the first shaft 501;

[0094] The one-way shaft groove 71 is integrally formed on a side of the second shaft body 502 close to the one-way shaft body 70 and is adapted to the one-way shaft body 70;

[0097] refer to Figure 4-6 In this embodiment, a supporting device is provided in the pool body. When the cylinder is immersed in the pool body, the bottom of the cylinder contacts the supporting shaft, and the supporting shaft cooperates with the sealing plug to clamp the cylinder. Then the clamping plate can be loosened (the clamping plate is moved out from the gap between adjacent cleaning shafts) to make the outer wall of the cylinder fully contact with the water in the pool body, thereby improving the detection effect.

[0098] Before detection, the support device of this embodiment can also clean the outer wall of the cylinder. The sprocket is started by the second motor and the first shaft is rotated. During cleaning, the first shaft is controlled to rotate counterclockwise. At this time, the limit block and the limit bevel in the one-way structure slip, so that the second shaft does not rotate, and the first shaft and the drive disk rotate. The cooperation of the driven gear and the ring gear makes the cleaning shaft revolve and rotate on the outer wall of the cylinder, thereby completing the cleaning of the cylinder.

[0099] During inspection, the first shaft is controlled to rotate clockwise, thereby driving the second shaft to rotate through the unidirectional rotation structure, and causing the cylinder to rotate. In the rotating state, if there are unqualified defects such as gaps on the outer wall of the cylinder, it is easier to discharge the internal air, which is conducive to inspection.

[0100] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
