Description

Technical Field

[0001] The present invention relates to the technical field of air compressor detection, in particular to an air compressor tank air tightness detection device. Background Art

[0002] Air compressors are used as a power source for compressed air in various industries of mechanical manufacturing. Gas storage tanks are devices specifically used by air compressors to store gas. Air tightness is an important indicator of the quality of gas storage tanks. In the existing technology, when performing air tightness testing on gas storage tanks, in order to accurately obtain the leak point, high-temperature and high-pressure gas is injected into the gas storage tank and the leak point is located using infrared cameras.

[0003] A search revealed a Chinese patent with publication number CN217331544U, which discloses an air tightness detection device for an air compressor gas tank. A hot air supply mechanism delivers high-temperature, high-pressure gas into the gas tank through an air pipe. If the gas tank is not airtight, an infrared camera will capture a temperature difference image indicating that the high-temperature gas is leaking from the tank. However, the following issues remain:

[0004] 1. Since the air compressor gas tank is made of metal, which has good thermal conductivity, the temperature of the air compressor gas tank will rise during long-term observation, making it impossible to use an infrared camera to observe the leak point. In addition, the purchase cost of the infrared camera is high.

[0005] 2. The lack of effective limit components for the air compressor gas tank causes the air compressor gas tank to shake easily during inflation;

[0006] 3. The air compressor tank cannot rotate, making it difficult to observe the leakage point. Summary of the Invention

[0035] Reference Figures 1-8 , a device for detecting air tightness of an air compressor tank, comprising a detection box body 1, characterized in that a tank support mechanism 2 which can slide in or out of the detection box body 1 is provided inside the detection box body 1, a limiting mechanism 3 for supporting the tank support mechanism 2 is provided inside the detection box body 1, a handle assembly 20 which can slidably cooperate with the limiting mechanism 3 is provided inside the tank support mechanism 2, tank fixing mechanisms 5 for clamping and driving the tank to rotate along the axis are provided on both sides of the tank support mechanism 2, driving mechanisms 4 for driving the tank fixing mechanism 5 to move in the vertical direction are provided on both sides of the interior of the detection box body 1, and an air supply mechanism 6 for inflating the tank is provided inside the tank fixing mechanism 5.

[0036] In particular, in the present invention, an operation panel 101 is provided on the outside of the detection box body 1, and three buttons are provided on the operation panel 101. The upper and lower buttons are used to control the forward and reverse rotation of the motor, so that the tank fixing mechanism 5 can move up and down. The middle one is the air pump 601 switch, and a water tank 102 is provided inside the detection box body 1, and a plug-in slot 103 is provided on the side of the detection box body 1.

[0037] It should be noted that the tank support mechanism 2 includes a hollow fixed base plate 201 with an arc-shaped slot 203 on the upper part. The fixed base plate 201 is slidably inserted into the plug-in slot 103. The lower part of the fixed base plate 201 is integrally formed with two sets of symmetrically arranged guide rails 202, and the lower part of the plug-in slot 103 is correspondingly provided with a limiting slide 104. The upper part of the limiting slide 104 is installed with a fixed slide 105, which cooperates with the guide rail 202. The arc-shaped slot 203 on the fixed base plate 201 can support the air compressor tank body, facilitate the connection between the tank fixing mechanism 5 and the air supply mechanism 6 on the side of the air compressor, and the fixed slide 105 can allow the fixed base plate 201 to slide stably and smoothly.

[0038] The handle assembly 20 includes a receiving groove 204 provided on the side of the fixed bottom plate 201, and the handle body 205 is slidably inserted into the interior of the receiving groove 204. The limiting mechanism 3 includes two groups of symmetrically arranged bottom plate support plates 301 welded and fixed to the side wall of the detection box body 1, and the bottom plate support plates 301 are provided with snapping holes 302. When the fixed bottom plate 201 slides to the outermost part, the handle body 205 is inserted into the inner locking of the snapping holes 302. The bottom plate support plate 301 is formed by integrally forming a horizontal plate and an inclined plate, and has high structural strength. The bottom plate support plate 301 can support the fixed bottom plate 201 and the tank body, and when the fixed bottom plate 201 slides to the middle of the tank body fixing mechanism 5, the handle body 205 falls and limits the fixed bottom plate 201, ensuring that the position of the fixed bottom plate 201 remains unchanged when the air compressor tank body is loaded.

[0039] It should be noted that the driving mechanism 4 includes an upper horizontal plate 401 and a lower horizontal plate 402, and two groups of symmetrically arranged reinforcements 403 are welded to the sides of the upper horizontal plate 401 and the lower horizontal plate 402. The sides of the reinforcements 403 are welded and fixed to the inner wall of the detection box body 1, and the upper end of the upper horizontal plate 401 is installed with a driving motor 404 by bolts, and the output shaft of the driving motor 404 is connected to the threaded rod 405 through a flat key transmission, and the upper part of the lower horizontal plate 402 is installed with a sealed bearing 406, and the lower end of the threaded rod 405 is inserted into the sealed bearing 406, and a guide rod 407 is welded and fixed between the upper horizontal plate 401 and the lower horizontal plate 402, and the two driving motors 404 rotate synchronously through the controller.

[0040] In particular, in the present invention, the tank body fixing mechanism 5 includes a central fixing part 501, and the side of the central fixing part 501 is integrally formed with a threaded seat 502 and a guide seat 503. The threaded seat 502 and the threaded rod 405 are threadedly connected, and the guide rod 407 is inserted into the guide seat 503. The threaded rod 405 is driven to rotate by the driving motor 404, which can drive the central fixing parts 501 on both sides to move up and down synchronously.

[0041] It should be noted that a sealed bearing 2 504 is embedded inside the central fixed part 501, and a rotating part 505 is fixedly installed on the inner ring of the sealed bearing 2 504. Six groups of pneumatic telescopic cylinders 506 are installed on the side of the rotating part 505. The piston end of the pneumatic telescopic cylinder 506 is fixed with an arc-shaped fixing plate 507 by bolts. The distance between the two opposite arc-shaped fixing plates 507 in the open state is much larger than the diameter of the air compressor tank body, and sufficient space is reserved for the air compressor tank body to be converted from a vertical state to a horizontal state. The pneumatic telescopic cylinder 506 can drive the arc-shaped fixing plate 507 to press the side wall of the air compressor tank body for fixing.

[0042] In particular, in the present invention, the air supply mechanism 6 includes an air pump 601 installed on the top of the detection box body 1. The air outlet of the air pump 601 is connected to a three-way pipe 602. An air pressure sensor is provided inside the three-way pipe 602, and a one-way valve is installed in the upper end of the three-way pipe 602. After the air pump 601 stops supplying gas, the air pressure sensor can identify the air pressure change in the three-way pipe 602, thereby determining whether the gas tank is leaking. The two ends of the three-way pipe 602 are connected to rubber hoses 603. The rubber hose 603 One end is connected to the tank inflation pipe 604, and a through hole 510 is opened in the center of the rotating part 505. The tank inflation pipe 604 is inserted into the through hole 510, and the two ends of the tank inflation pipe 604 are integrally formed with a limiting portion 605. The end of the tank inflation pipe 604 is integrally formed with a threaded connection portion 606. The tank inflation pipe 604 can rotate and retract, so as to be connected with different models of air compressor tanks. The air pump 601 can inject air into the air compressor tank through a series of pipes to test the air tightness.

[0043] The present invention is divided into the following steps when used:

[0044] S1: Before starting, the operation panel 101 is used to control the drive motor 404 to raise the tank fixing mechanism 5 to a suitable height, and the pneumatic telescopic cylinder 506 is controlled to push the arc-shaped fixing plate 507 to the outermost end of the stroke;

[0045] S2: Pull the handle body 205 to pull the fixed base plate 201 into the detection box body 1, lift the handle body 205 upward and continue to pull it outward and insert the handle body 205 into the clamping hole 302 on the base support plate 301 to lock the fixed base plate 201;

[0046] S3: Move the air compressor tank body upright into the detection box body 1 and place it on the fixed bottom plate 201. Then rotate the air compressor tank body horizontally 90 degrees so that the air compressor tank body falls into the arc-shaped slot 203 of the fixed bottom plate 201.

[0047] S4: The arc-shaped fixing plate 507 is retracted by controlling the pneumatic telescopic cylinder 506, and the arc-shaped fixing plate 507 presses the side wall of the air compressor tank body to achieve fixation;

[0048] S5: Pull the tank inflation tube 604 on both sides of the tank body and rotate it into the tank body through the threaded connection part 606, and the outside of the threaded connection part 606 needs to be wrapped with raw tape;

[0049] S6: The operation panel 101 is then used to control the drive motor 404 to raise the tank fixing mechanism 5, separate the tank from the fixed base plate 201, release the lock between the handle body 205 and the engaging hole 302, and push the fixed base plate 201 to the rear of the detection box body 1 to make way for the tank fixing mechanism 5 and the tank to move downward;

[0050] S7: The driving motor 404 is then controlled by the operation panel 101 to lower the tank fixing mechanism 5, and the tank stops when the tank is completely immersed in the water tank 102;

[0051] S8: Control the air pump 601 through the operation panel 101 to fill a certain amount of gas into the tank, then slowly rotate the tank to observe the leak point on the tank surface to perform the test;

[0052] S9: After the inspection is completed, the tank fixing mechanism 5 is first raised to the highest point by controlling the drive motor 404, and then the fixed base plate 201 is pulled out and fixed according to the steps in S2. Then, the drive motor 404 is controlled to move the tank fixing mechanism 5 downward so that the gas storage tank falls onto the arc-shaped slot 203 of the fixed base plate 201;

[0053] S10: Control the pneumatic telescopic cylinder 506 to extend the arc-shaped fixing plate 507 to the outermost end of the stroke, rotate and remove the tank inflation tube 604, and then rotate the tank 90° and move it out.
