The principle of applying an air tightness detection device for an air spring to other types of equipment is substantially the same as the principle applied to air springs, and will not be elaborated here.

[0027] See also Figure 1-Figure 3 ,in Figure 1 This is a structural schematic diagram of an air tightness detection device for an air spring in an embodiment of the utility model. An air tightness detection device for an air spring includes a fixing device 1 and a drying device 2. The fixing device 1 includes a vertical plate 11, a plurality of cylinders 12 and a U-shaped rod 13. The top of the vertical plate 11 is fixedly connected to a horizontal plate 111, and each cylinder 12 is fixedly connected to the bottom of the horizontal plate 111. The U-shaped rod 13 is located directly below each cylinder 12, and both ends of the U-shaped rod 13 are fixedly connected to the bottom of the horizontal plate 111. The U-shaped rod 13 is rotatably connected to a plurality of inflation platforms 131, and each inflation platform 131 corresponds to each cylinder 12 one by one, and each inflation platform 131 is provided with an air inlet 1311 and an air outlet 1312. The drying device 2 includes a fan 22, and the fan 22 is connected to the vertical plate 11. The fan 22 is used to air-dry water stains on the surface of the air spring.

[0028] In this embodiment, each inflation table 131 is rotatably connected to the U-shaped rod 13, so that after the air tightness inspection of the air spring is completed, the staff can drive the air spring to rotate by rotating the inflation table 131, so that the fan 22 can dry the water stains on the surfaces of the air spring. Compared with the traditional unidirectional drying process, the air spring in the utility model has a better drying effect.

[0029] First, the bottom end of each air spring is placed on the inflation table 131 in one-to-one correspondence with each cylinder 12; then, each cylinder 12 is started synchronously, and the cylinder 12 cooperates with the inflation table 131 on the U-shaped rod 13 to clamp each air spring; then, the air inlet 1311 and the air outlet 1312 are respectively connected to the external air supply system, and when the cylinder 12 is immersed in water, the external air supply system is started to observe whether the air spring generates bubbles in the water; finally, after the inspection, the air spring leaves the water, and the fan 22 is started to release the pressure of each cylinder 12, and the connection pipe between the inflation table 131 and the external air supply system is released, and each inflation spring is driven to rotate by rotating each inflation table 131, so that the surface water stains of the air spring in all directions can be dried by air.

[0030] It should be noted that before the inflation platform 131 is rotated, the connection pipes between the inflation platform 131 and the external air supply system need to be released to avoid the connection pipes from being entangled and damaged.

[0031] Furthermore, the cylinder 12 preferably adopts a single-axis cylinder. The arrangement of multiple cylinders 12 enables the device to perform air tightness detection on multiple air springs, thereby improving the detection efficiency.

[0032] Furthermore, the fixed end of each cylinder 12 is fixedly connected to the bottom of the horizontal plate 111, the movable end of each cylinder 12 faces the U-shaped rod 13, and each cylinder 12 is controlled by a computer PLC end, thereby achieving synchronous operation of each cylinder 12.

The motor 23 is used to drive the round rod 211 to rotate and drive the air guide plate 21 to rotate.

[0041] In this embodiment, the motor 23 adopts a servo motor to realize different steering directions of the air guide plate 21, which is convenient for drying air springs of different sizes. The end of the through hole 113 away from the square groove 112 is fixedly connected with a U-shaped bracket, and the fixed end of the motor 23 is fixedly installed on the side of the U-shaped bracket away from the through hole 113. The output end of the motor 23 passes through the U-shaped bracket and is fixedly connected to the round rod 211, thereby realizing that the motor 23 drives the air guide plate 21 to rotate.

[0042] Furthermore, in order to better guide the direction of wind force, the number of wind guide plates 21 is preferably two, and the two wind guide plates 21 are synchronized by three gears meshing with each other, that is, the output end of the motor 23 is fixedly connected to the first gear, and when the motor 23 drives one wind guide plate 21 to rotate, it will drive the first gear to rotate together, and the end of the round rod 211 of the other wind guide plate 21 is also fixedly connected to the second gear, and the first gear and the second gear are both rotatably connected between the vertical plate 11 and the side walls opposite to the U-shaped bracket, and a third gear is provided between the first gear and the second gear, and the two sides of the third gear are respectively rotatably connected to the side walls opposite to the vertical plate 11 and the U-shaped bracket, and the first gear, the third gear and the second gear are meshed with each other in sequence. The function of the third gear is to make the first gear and the second gear run synchronously, thereby realizing the synchronous operation of the two wind guide plates 21.

[0044] In this embodiment, the driving member 33 adopts a double-axis cylinder, and a crossed lifting rod is installed under the lifting platform 32. The two ends of the driving member 33 are respectively hinged to the bottom plate and the lifting rod. The driving member 33 realizes the lifting of the lifting platform 32 by driving the lifting rod.

[0045] Furthermore, the bottom of the driving member 33 is fixedly connected to a bottom plate, and a universal wheel is installed at the bottom of the bottom plate to facilitate the movement of the immersion device 3.

[0046] In one embodiment, see Figure 1 The length of the lifting platform 32 is the same as the length of the water tank 31 , and the width of the lifting platform 32 is greater than the width of the water tank 31 .

[0047] In this embodiment, both ends of the lifting platform 32 in the length direction are aligned with both ends of the water tank 31, one side of the lifting platform 32 in the width direction is aligned with one side of the water tank 31, and the other side of the lifting platform 32 exceeds the other side of the water tank 31 to form a platform, which is convenient for workers to stand on the platform to operate, improve the operating height of the workers, and facilitate loading and unloading of each air spring.

[0048] In one embodiment, see Figure 1 The inner walls of the water tank 31 at opposite ends are provided with guide grooves 311 , and the two ends of the U-shaped rod 13 are respectively slidably embedded in the two guide grooves 311 .

[0049] In this embodiment, the U-shaped rod 13 is stationary, and the guide groove 311 is continuously raised and lowered with the water tank 31. The guide groove 311 and the U-shaped rod 13 are mutually limited to ensure that the U-shaped rod 13 is always immersed in water along the direction of the guide groove 311, thereby preventing the U-shaped rod 13 from deforming during long-term use and affecting the loading and unloading of each air spring.

[0050] In one embodiment, see Figure 1 An observation window 312 is installed on the side of the water tank 31 away from the vertical plate 11.

[0051] In this embodiment, the observation window 312 is made of a transparent acrylic plate, which is convenient for the staff to check the airtightness of each air spring in water in real time.

[0052] In one embodiment, see Figure 2 A reinforcing rib 114 is fixedly connected between the vertical plate 11 and the horizontal plate 111 .

[0054] In order to better understand the present invention, the following Figures 1 to 3 The technical solution of the utility model is described in detail:

[0055] First, the bottom ends of the air springs are placed on the inflation platforms 131 one by one, and the air inlets 1311 and the air outlets 1312 of the air springs are connected to the external air supply system, so as to inflate the air springs in the water.

Subsequently, the driving member 33 is started, and the lifting platform 32 drives the water tank 31 to rise until the air springs are immersed in the water.

Finally, after the inspection is completed, the driving member 33 is started, and the lifting platform 32 drives the water tank 31 to rise until the air springs are immersed in the water. 33 drives the lifting platform 32 and the water tank 31 to descend until the air spring leaves the water, releases the pressure of the cylinder 12, releases the connection between the air inlet 1311 and the air outlet 1312 and the external pipeline, starts the fan 22, and starts the motor 23 to adjust the direction of the wind guide plate 21, and uses the angled wind force to remove the water stains on the surface of each air spring. At the same time, the inflation platform 131 is rotated to drive the air spring to rotate, so that the wind force can dry the water stains on the surfaces of the air springs. Compared with the traditional unidirectional drying process, the air spring in the utility model has a better drying effect.
