[0002] Hydraulic pipes are pipes or piping systems used to transport hydraulic fluid (usually hydraulic oil). They play a key role in hydraulic systems, transporting hydraulic fluid to achieve the system's power transmission, control, and actuation functions. Hydraulic pipes typically connect components such as hydraulic pumps, valves, and actuators, transferring hydraulic energy to the required locations to enable the movement, control, and operation of mechanical equipment. Testing the airtightness of hydraulic pipes is a crucial step in ensuring the proper operation of hydraulic systems and preventing leaks.

[0028] See also Figure 1-5: The inner side of the detection water tank 1 is provided with a slide groove 81, and there are two slide grooves 81. The two sides of the detection plate 2 are fixedly connected with a first slider 82 and a second slider 83. The detection plate 2 can install and fix the first slider 82 and the second slider 83.

Both ends of the limiting rod 9 are fixedly connected to the detection water tank 1 through the slide groove 81. The detection water tank 1 can be connected to the limiting rod 9 through the slide groove 81, and the limiting rod 9 can limit the second slider 83. This makes it more stable when the detection plate 2 moves up and down through the rotation of the one-way screw 84, and is less likely to shake or rotate slightly, thereby increasing the stability of the hydraulic pipe when being tested for air tightness.

[0031] See also Figure 1 and Figure 7The upper side of the detection plate 2 is fixedly connected with a first fixing block 71, and the upper side of the first fixing block 71 is rotatably connected to a limiting ring block 72. The lower side of the limiting ring block 72 is fixedly connected with a second fixing block 73, and the lower side of the second fixing block 73 is fixedly connected with a second clamping block 75. A second clamping groove 74 is provided on the upper side of the detection plate 2, and the second clamping block 75 is movably clamped on the inner side of the second clamping groove 74. The first fixing block 71 can be connected to the second fixing block 73 through the limiting ring block 72, and when the second clamping block 75 on the lower side of the second fixing block 73 is clamped to the inner side of the second clamping groove 74, the second fixing block 73 and the limiting ring block 72 can be stably connected to the upper side of the detection plate 2. The setting of the limiting ring block 72 enables, when the hydraulic pipe to be tested is too long, the hydraulic pipe can be placed on the upper side of the detection plate 2 in an S shape, and the limiting ring block 72 can limit and press the hydraulic pipe, so that the hydraulic pipe is not easy to warp or be unevenly placed when being tested.

[0032] See also Figure 1 : A reinforcement plate 10 is fixedly connected to one side of the detection water tank 1, and the upper side of the reinforcement plate 10 is fixedly connected to the first connecting plate 4. The reinforcement plate 10 can reinforce the first connecting plate 4 through the connection between itself, the detection water tank 1 and the first connecting plate 4, so that the first connecting plate 4 and the air pump 36 can be sufficiently stable during use and are not prone to tilting, shaking or falling.

[0033] Working principle: When the present invention is used, the staff can place the hydraulic pipe that needs to be tested for air tightness on the upper side of the test plate 2, and connect the two ends of the hydraulic pipe to the air outlet pipe 32 and the air inlet pipe 33 respectively. After the connection is completed, start the servo motor 85. Through the operation of the servo motor 85, the one-way screw 84 is driven to rotate, and the one-way screw 84 can smoothly drive the test plate 2 to move downward when rotating. When the test plate 2 moves downward, it can smoothly drive the hydraulic pipe into the water source inside the test water tank 1. After that, the staff can start the air pump 36 to pump gas into the inside of the hydraulic pipe through the air pump 36. At this time, the staff can judge whether the air tightness of the hydraulic pipe is qualified by observing whether there are bubbles in the water source.

[0034] When the inspection is completed, the staff can take out the inspected hydraulic pipe from the upper side of the inspection plate 2 and place it on the upper side of the second wiping sponge 55, and then inspect other hydraulic pipes. When inspecting other hydraulic pipes, the downward movement of the inspection plate 2 will drive the first wiping sponge 53 to move downward together. When the first wiping sponge 53 moves down to a certain distance, the first wiping sponge 53 can cooperate with the second wiping sponge 55 to absorb and clean the water stains on the outside of the hydraulic pipe inspected last time, thereby reducing the situation where there are too many water stains on the surface or inside of the hydraulic pipe after the air tightness inspection is completed.
