Description

Technical Field

[0001] The utility model relates to the technical field of gas container leakage detection, in particular to a composite material gas storage cylinder sealing detection device. Background Art

[0002] Most of the existing leak detection methods for automobile brake system air cylinders are still to fill the air cylinder with air, then apply soapy water to the welds and interfaces with a brush to see if there are any bubbles. There are also methods to fill low-pressure gas into the cavity of the part and use a tester to test the gas leakage by pressure drop or pressure difference method, but the above methods are not suitable for composite material air cylinder products. Applying soapy water takes a lot of time, which not only makes the labor intensity high and the work efficiency low, but also makes small leaks difficult to observe and find, which will affect the test results and make the test quality difficult to guarantee; when using a tester to test by pressure drop or pressure difference method, since the commonly used test instrument uses a pressure of no more than 1.0Mpa, it cannot meet the requirement of 1.8Mpa for the maximum inflation pressure of the air seal test of the air cylinder. In addition, it can only test a single product, and the test efficiency is low, which cannot meet the production rhythm.

[0003] Therefore, it is necessary to design a composite material gas storage cylinder sealing detection device to improve the above-mentioned problems. Utility Model Content

[0029] Reference Figures 1 to 5A composite material gas cylinder sealing detection device comprises a steel structure frame 1, a water tank 2, a lifting part 3, and a clamping part 4. The bottom bracket of the steel structure frame 1 is welded with 50x50 square steel pipes, the columns and longitudinal beams are welded with 80x80 square steel pipes, and the transverse beams are welded with 40x40 square steel pipes. A lighting tube (not shown) is arranged on the upper part of the steel structure frame 1; the water tank 2 with an upper opening is arranged at the lower part of the steel structure frame 1, the length, width and height of the water tank 2 are 2000x1200x600mm, the water tank 2 is welded with stainless steel plates, the periphery is reinforced with 30x30 stainless steel square pipes, and a drain valve (not shown) is arranged at the bottom; the lifting part 3 is connected to the steel structure frame 1, and the lifting part 3 is used to lift the gas cylinder 5 so that the gas cylinder 5 enters the water tank 2 or is separated from the water in the water tank 2; the clamping part 4 is connected to the lifting part 3, and the clamping part 4 is used to clamp the gas cylinder 5 so as to better fix the gas cylinder 5 during the detection process.

[0030] The lifting part 3 includes a guide sleeve bracket 31, a guide sleeve 32, a guide rod 33, an aluminum profile frame 34, and a lifting cylinder 35. The guide sleeve bracket 31 is arranged on the upper part of both sides of the steel structure frame 1. The guide sleeve 32 is fixed to the guide sleeve bracket 31 by using an M12U-type screw. The guide rod 33 is slidably arranged up and down in the guide sleeve 32. The guide rod 33 is preferably a solid optical axis with a diameter of 50mm. The aluminum profile frame 34 and the guide rod 33 are fixedly connected by U-shaped screws and nuts. The aluminum profile frame 34 adopts 40x80 aluminum profile with anchors. The lifting cylinder 35 is fixed with bolts, and the two ends of the lifting cylinder 35 are respectively connected to the upper part of the steel structure frame 1 and the aluminum profile frame 34. The specification of the lifting cylinder 35 is SE-100x400 rear hinged axis pull rod cylinder. The lifting cylinder 35 is floatingly connected with the aluminum profile frame 34 to avoid interference between the cylinder piston rod and the guide rod 33. The floating connection mainly refers to the gap between the connecting shaft 351 at the front end of the piston rod of the lifting cylinder 35 and the split pressure block 352 arranged on the aluminum profile frame 34. This non-rigid connection can prevent the cylinder piston rod from being subjected to radial force.

[0031] The clamping part 4 includes a support block 41, a clamping cylinder 42, and a clamping block 43. The support block 41 is arranged at the bottom of the aluminum profile frame 34 to support the gas storage cylinder 5.

Figure 5 As shown, three clamping cylinders 42 are provided, and the specifications of the clamping cylinder 42 are double-guide rod cylinders TCL-40x200. The clamping block 43 is arranged at the front end of the piston rod of the clamping cylinder 42. The number of the V-shaped clamping blocks 43 matches the supporting block 41. Three clamping blocks 43 are provided. The supporting block 41 and the clamping block 43 are made of nylon material. The clamping cylinder 42 can move downward to stably fix the air storage cylinder 5 through the clamping block 43 and the supporting block 41.

[0032] The utility model also includes a control cabinet and a valve group (not shown). Electrical components and valve groups are installed inside the control cabinet. The valve groups are all solenoid valves. The solenoid valves are switched by buttons to control the actions of each cylinder and the inflation action, thereby realizing clamping, lifting, inflation and exhaust actions.

[0033] The following will refer to Figures 1 to 5 , the working principle of the utility model is explained.

[0034] Initial state: the lifting cylinder 35 and the clamping cylinder 42 are all retracted, the clamping part 4 is in the open state, the aluminum profile frame 34 is in the raised state, the air source switch is turned on, and the booster cylinder enters the working state.

[0035] Loading, place the three air cylinders 5 to be tested on the support block 41 in turn and plug in the inflation quick connector, press the clamping button, the three clamping cylinders 42 descend at the same time and clamp the air cylinder 5, press the descending button of the lifting cylinder 35, the lifting cylinder 35 extends to press the aluminum profile frame 34 and the air cylinder 5 into the water in the water tank 2, press the button to start low-pressure inflation, start inflation, and keep the inflation state when the inflation pressure reaches the set value. Start to observe whether there are bubbles visually. After the observation is completed, press the button to exhaust, the button to raise, and the button to open in turn. The aluminum profile frame 34 rises, and the air cylinder 5 leaves the water surface. After the exhaust is completed, pull out the inflation quick connector, remove the air cylinder 5 and place it in the appliance to complete a working cycle.
