It should be understood that the specific examples described herein are only used to explain the utility model and not to limit the utility model.

[0023] The specific implementation of the utility model will be described in detail below in combination with specific examples.

[0024] Please refer to Figures 1 to 5 The ton barrel air tightness detection mechanism provided by the utility model embodiment includes a rack 1, the rack 1 is provided with an inflatable test assembly 2; further including a roller conveyor belt 11 passing through the inflatable test assembly 2 is also installed on the rack 1, and a pressure gauge is installed on the pipeline structure of the inflatable test assembly 2; two sets of symmetrical correction assemblies 3 are fixed on the inner side of the rack 1, and a space for the ton barrel to pass through is formed between the two sets of correction assemblies 3, the correction assembly 3 includes a plurality of vertically arranged and horizontally distributed guide wheels 32; a transverse stop 4 is also fixed on one side of the rack 1, the transverse stop 4 includes a transverse rod 44 that can contact the advancing surface of the ton barrel; two sets of symmetrical vertical extrusion 5 are also fixed on the other side of the rack 1, the vertical extrusion 5 includes a rotating arm 53, and a pressing block 55 that can contact the top surface of the ton barrel is detachably connected to one end of the rotating arm 53.

[0025] It should be noted that: in the test device, the structure and use principle of the inflatable test assembly 2 are described in detail in the cited document "CN 220136588 U", which will not be repeated here.

[0026] The pipeline structure of the inflation test assembly 2 has a gas conveying function, and when the inflation operation is performed, the pipeline structure is communicated with the inside of the ton barrel, so that the gas is conveyed to the inside of the ton barrel. In the embodiment, a pressure gauge is installed on the pipeline structure to replace the water tank in the cited document, and the pressure gauge monitors the pressure change in the ton barrel in real time, so that the air tightness of the ton barrel can be known.

[0027] For the loading and unloading of the ton barrel, a roller conveyor 11 is arranged in the rack 1, and the ton barrel can be directly placed on the roller conveyor 11, and then the ton barrel is conveyed by the roller conveyor 11 to realize the loading and unloading operation of the ton barrel.

[0028] The width of the ton barrel is smaller than the width of the rack 1, so the ton barrel has a certain spacing on both sides of the rack 1, and in general, the spacing on both sides will be different. Therefore, a correction assembly 3 is arranged in the rack 1, and the correction assembly 3 is composed of two groups, and the two groups have a spacing for the ton barrel to pass through, so that the position of the ton barrel can be closer to the center line of the roller conveyor 11, and the position of the ton barrel can be corrected. The correction assembly 3 is limited by the guide wheel 32, and the guide wheel 32 can rotate, so it will not directly hinder the transportation of the ton barrel.

[0029] The transverse stop piece 4 has a positioning function for the ton barrel, that is, after the ton barrel in the conveying process contacts the transverse rod 44, the transverse rod 44 has a blocking effect, so that the ton barrel stops moving (at this time, the roller conveyor 11 can be stopped), so that the position of the ton barrel corresponds to the position of the inflation test assembly 2, which is beneficial to the subsequent air tightness test operation.

[0030] The vertical extrusion piece 5 has a fixing function for the ton barrel, that is, when the pressing block 55 contacts the upper end of the ton barrel by rotating the rotating arm 53, the ton barrel is extruded, so that the ton barrel can be kept in a stable state, and the safety of the test operation can be further improved.

[0031] In the embodiment of the utility model, please refer to Figure 3 The inside of the rack 1 is bolted with an arch bridge-shaped mounting bracket 31, and the guide wheel 32 is rotationally connected to the mounting bracket 31.

[0032] It should be noted that the mounting bracket 31 is the mounting structure of the guide wheel 32.

[0033] In the embodiment of the utility model, please refer to Figure 4 The transverse stop piece 4 further comprises a first foot 41, the first foot 41 is bolted on one side of the rack 1, and the motor 42 is bolted on the first foot 41, and the output end of the motor 42 is welded with a vertical rod 43.

[0034] The two transverse rods 44 are welded and fixed to the circumferential outer wall of the vertical rod 43, and are driven by the vertical rod 43 to rotate by 90 degrees in the horizontal direction.

[0035] It should be noted that, in use, the motor 42 drives the vertical rod 43 to rotate, thereby driving the transverse rod 44 to rotate, so that the transverse rod 44 is arranged above the drum conveying belt 11, thereby intercepting the ton barrel and positioning the ton barrel. After the detection is completed, the transverse rod 44 is driven by the vertical rod 43 to rotate by 90 degrees, so that the ton barrel is not intercepted, and then the ton barrel can be conveyed by the drum conveying belt 11.

[0036] In the embodiment of the utility model, please refer to Figure 5 The vertical extrusion piece 5 comprises a second foot support 51, and the second foot support 51 is bolted to one side of the rack 1 and has a vertically arranged support arm 52 welded and fixed to the upper end of the second foot support 51.

[0037] The rotating arm 53 is rotatably connected to the upper end of the support arm 52 at a position close to the middle part, and the support arm 52 has a hydraulic cylinder 54 rotatably connected to a position close to the bottom part, and the output end of the hydraulic cylinder 54 is rotatably connected to one end of the rotating arm 53, so that the rotating arm 53 is driven to rotate in the vertical direction by the extension and retraction of the hydraulic cylinder 54, and the pressing block 55 is fan-shaped and is bolted to the rotating arm 53.

[0038] It should be noted that, in use, the hydraulic cylinder 54 is extended to drive the rotating arm 53 to rotate, and the pressing block 55 at the other end of the rotating arm 53 is lowered to contact the ton barrel and extrude the ton barrel, thereby fixing the ton barrel. After the air tightness detection is completed, the rotating arm 53 is driven by the hydraulic cylinder 54 to rotate reversely to release the restriction of the pressing block 55 on the ton barrel.

[0039] In the embodiment of the utility model, please refer to Figure 3 And Figure 5 The circumferential outer wall of the guide wheel 32 and the lower surface of the pressing block 55 are both bonded with rubber-made gaskets 6.

[0040] It should be noted that the gaskets 6 can reduce the frictional force during the ton barrel conveying and fixing operation, thereby reducing the surface wear.

[0041] The circuit and control involved in the utility model are prior art, and will not be described in detail here.

[0042] The above is only an embodiment of the utility model, and does not limit the patent range of the utility model, and any equivalent structure or equivalent process conversion made by using the contents of the utility model specification and drawings, or direct or indirect application in other related technical fields, are also included in the patent protection range of the utility model.
