Description

Technical Field

[0001] This utility model relates to the field of oil and gas recovery system technology, and in particular to a performance testing device for oil and gas recovery hose joints. Background Technology

[0002] When refueling a car at a gas station, to reduce the pollution and waste caused by gasoline vapors evaporating into the atmosphere, a vapor recovery system is used to draw the vapors evaporating from the fuel tank opening back into the fuel tank. The vapor recovery system includes a vapor recovery hose that connects the fuel dispenser and the car's fuel tank opening. At the end of the hose is a quick-connect coupling with a retaining spring inside. This quick-connect coupling allows for a rapid locking mechanism when inserted into the receiving tube on the fuel tank opening, accompanied by a "click" sound to indicate proper locking. The retaining spring also maintains a seal, ensuring a tight connection between the fuel and vapor lines and the fuel tank during refueling, preventing leakage of liquid fuel and vapors. After refueling, it can be safely disengaged, allowing the gas station attendant to safely remove the coupling from the fuel tank opening. However, over time, repeated insertion and removal can cause mechanical wear on the retaining spring. Furthermore, the dragging and twisting of the hose during refueling generates continuous high-frequency micro-vibrations at the coupling, which can cause wear between the retaining spring and the receiving tube, leading to fatigue failure of the retaining spring. Traditional testing methods include manual insertion and removal tests, or testing using a general-purpose fatigue testing machine.

[0003] However, existing testing methods have certain limitations. Manual insertion and removal testing can only simulate the insertion and removal action and cannot simulate continuous vibration conditions, resulting in a large deviation between the test results and the actual lifespan. Furthermore, the testing is inefficient, labor-intensive, and lacks standardized testing standards. In addition, using a general-purpose fatigue testing machine is not feasible due to its low matching degree, as it cannot accurately simulate the stress state and motion trajectory of the hose joint, leading to test results that do not match reality. Therefore, it is difficult to establish an accurate system for detecting the wear life of snap rings. Utility Model Content

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0023] Reference Figures 1 to 4 As shown, this utility model discloses a performance testing device for oil and gas recovery hose joints, including a workbench 1.

[0024] The performance testing device for oil and gas recovery hose joints also includes at least one testing unit.

[0025] Specifically, at least one of the test units includes a connecting plate 20, a clamping assembly 21, a first driving assembly 22, and a second driving assembly 23.

[0026] The clamping assembly 21 is mounted on the worktable 1. One end of the test piece is fixed to the clamping assembly 21, and the other end of the test piece is connected to the movable end of the first driving assembly 22 so that it can rotate (oscillate) around its own axis under the action of the first driving assembly 22, thereby simulating and applying vibration conditions to the test piece.

[0027] The second drive assembly 23 is mounted on the workbench 1, and the connecting plate 20 is connected to the movable end of the second drive assembly 23. The output end of the second drive assembly 23 moves along a first direction. The first drive assembly 22 is mounted on the connecting plate 20, so that the first drive assembly 22 can move along the first direction under the drive of the second drive assembly 23; thereby, it can apply a plugging and unplugging action to the test piece for plugging and unplugging testing.

[0028] It should be noted that, in this embodiment, the test piece is an oil and gas recovery hose, and one end of the oil and gas recovery hose with a retaining spring is connected to the movable end of the first drive assembly 22.

[0029] When multiple test units are provided, and these test units are arranged side by side along the length of the workbench 1, batch testing of the oil and gas recovery hoses can be carried out.

[0030] The oil and gas recovery hose joint performance testing device also includes a control unit, which has a communication connection with at least one of the testing units, thereby controlling the operation of the testing units.

[0031] Therefore, it can be understood that the performance testing device for oil and gas recovery hose connectors protected by this utility model includes a workbench, at least one testing unit, and a control unit. The testing unit is located on the workbench and includes a connecting plate, a clamping assembly, a first driving assembly, and a second driving assembly. The first driving assembly is used to drive the test piece to rotate to simulate vibration testing; the second driving assembly is used to apply a pulling force to the test piece to cooperate with the clamping assembly to simulate insertion and removal testing. Thus, this utility model can simulate the combined working conditions of insertion / removal and vibration in real use, and simultaneously or alternately perform insertion / removal actions and simulated vibration conditions, thereby realistically reproducing the stress state of the retaining spring of the oil and gas recovery hose connector under test in actual use, so as to detect the wear life of the retaining spring. This utility model can improve the testing efficiency, realize automated cyclic testing, and accurately record parameters such as the number of cycles and monitoring force value changes with the control unit. Furthermore, it can also ensure the reliability and safety of the oil and gas recovery connector during use and avoid oil and gas leakage caused by retaining spring failure.

[0032] In a preferred embodiment, the testing unit further includes a base plate 10, which is mounted on the workbench 1; the clamping assembly 21 and the second driving assembly 23 are mounted on the base plate 10.

[0033] Furthermore, the clamping assembly 21 includes a limiting support block 210, a movable block 211, a clamping drive component 212, and a drive mounting base 213.

[0034] The support block 210 is mounted on the base plate 10, and the clamping drive member 212 is mounted on the base plate 10 via the drive mounting base 213. The movable block 211 is connected to the movable end of the clamping drive member 212, and the movable block 211 is disposed opposite to the limiting support block 210. The movable block 211 can move closer to or further away from the limiting support block 210 under the drive of the clamping drive member 212, thereby clamping or releasing the workpiece under test.

[0035] Furthermore, in order to improve the clamping stability of the clamping assembly 21 and ensure a stable connection between the test piece and the clamping assembly 21 during the test, the side of the limiting support block 210 that contacts the test piece is configured to resemble the shape of the test piece.

[0036] In a preferred embodiment, the side of the movable block 211 that contacts the test piece is configured to resemble the shape of the test piece.

[0037] With this configuration, when the movable block 211 moves close to the phase support block 210 under the drive of the clamping drive member 212, a receiving space matching the shape of the test piece can be formed between the movable block 211 and the limiting support block 210, which is conducive to the stable clamping of the test piece.

[0038] Specifically, the first driving component 22 includes a first driving member 220 and a first connecting member. The first connecting member is installed on the movable end of the first driving member 220, and the device under test is connected to the first driving member 220 through the first connecting member.

[0039] Preferably, the first driving component 220 includes, but is not limited to, a swing cylinder (rotary cylinder).

[0040] In a preferred embodiment, the first connector includes a first clamping block 221 and a second clamping block 222 disposed opposite to each other, and the first clamping block 221 and the second clamping block 222 are fixed together by fasteners. The fasteners include, but are not limited to, bolts.

[0041] In a preferred embodiment, the second drive assembly 23 includes a second drive member 230 and a second connector 231.

The connecting plate 20 is connected to the second drive member 230 through the second connector 231.

[0042] In detail, the second connector 231 adopts a second connecting plate, one end of the second connecting plate is connected to the second driving component 230, and the other end of the second connecting plate is bent and connected to the connecting plate 20.

[0043] In order to guide and limit the movement of the connecting plate 20 along the first direction and ensure the accuracy of the insertion and removal position, the test unit further includes a guide rail 30 and a slider 31 slidably connected to the guide rail 30. The guide rail 30 is disposed on the base plate 10 along the first direction, and the slider 31 is fixedly connected to the bottom of the connecting plate 20.

[0044] Preferably, two sets of guide rails 30 are arranged side by side along the second direction, and two sets of sliders 31 are also arranged accordingly to ensure stability and force balance during guidance.

[0045] In this embodiment, five groups of test units are arranged side-by-side along the second direction on the workbench 1. It should be noted that the second direction is perpendicular to the first direction. Of course, in other embodiments, the number of test units can be adjusted according to requirements.
