[0022] S5: After the safety shoes are taken out of the immersion tank, the motor is started by controlling the PLC, and the start of the motor drives the rotation of the second threaded rod, the rotation of the second threaded rod drives the movement of the moving seat, the movement of the moving seat drives the movement of the lifting plate, and the movement of the lifting plate drives the movement of the rotating disk, so that the safety shoes move from the top of the immersion tank to the top of the observation tank;

[0023] S6: Then the motor is controlled to start and move the lifting plate downward, which drives the rotating plate downward, and the movement of the rotating plate drives the movement of the fixed plate.

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] like Figures 1 to 7 As shown, in an embodiment of the present invention, a safety shoe corrosion test device includes a device body 1, an immersion tank 2 and an observation tank 3 are arranged inside the device body 1, a moving seat 4 is arranged on one side of the device body 1, a lifting plate 5 is slidably installed inside the moving seat 4 through a moving component, a rotating disk 8 is installed at the bottom of the lifting plate 5 through a rotating component, and fixed plates 9 are arranged on both sides of the rotating disk 8, one end of the two fixed plates 9 is fixedly connected to a connecting plate 10, the two connecting plates 10 are embedded in the inside of the rotating disk 8, and a first spring 11 is installed between the two connecting plates 10;

[0038] The moving assembly includes a first threaded rod 6 embedded in the inner wall of the lifting plate 5, the lifting plate 5 and the first threaded rod 6 are threadedly connected, and a motor 7 is installed on the top of the first threaded rod 6;

[0039] A second threaded rod 14 is connected to the inner thread of one side of the moving seat 4 . The second threaded rod 14 is rotatably mounted on the inner wall of the device body 1 . A motor 15 is mounted at one end of the second threaded rod 14 .

[0040] It should be noted that the purpose of this test is to evaluate the corrosion degree of safety shoes in acid and alkali environments. It does not require drying, but directly observes the appearance changes of the material such as discoloration, blistering, cracking, etc.

[0041] When performing an acid and alkali resistance test on the safety shoes, firstly, the sole of the safety shoes is placed upright between the two fixing plates 9, and the elastic force of the first spring 11 causes the two fixing plates 9 to clamp and fix the safety shoes inwards;

[0042] Then, the motor 7 is started by controlling the PLC. When the motor 7 is started, the first threaded rod 6 is driven to rotate. The rotation of the first threaded rod 6 drives the movement of the lifting plate 5. The movement of the lifting plate 5 drives the movement of the rotating disk 8. The movement of the rotating disk 8 drives the movement of the fixed plate 9, so that the fixed plate 9 clamps the safety shoes and immerses them in the acid-base solution in the immersion tank 2;

[0043] After soaking, the motor 7 is started again to make the two fixing plates 9 clamp the safety shoes and take them out of the acid and alkali solution;

[0044] After taking out, the motor 15 is started by PLC control, the start of the motor 15 drives the rotation of the second threaded rod 14, the rotation of the second threaded rod 14 drives the movement of the moving seat 4, the movement of the moving seat 4 drives the movement of the lifting plate 5, the movement of the lifting plate 5 drives the movement of the rotating disk 8, so that the safety shoe moves from the top of the immersion tank 2 to the top of the observation tank 3, and is placed in the observation tank 3 for observation;

[0045] The device prevents the worker's skin from coming into contact with the safety shoes during the test, which not only improves the safety of the operation but also improves the test efficiency.

[0046] like Figure 1 and Figure 2 As shown, a filter screen 16 is fixedly installed inside the observation tank 3.

[0047] The acid and alkali solution remaining on the surface of the safety shoes is quickly discharged through the filter 16 to avoid the accumulation of liquid on the platform, making it easier to observe the effect.

[0048] like Figure 3 and Figure 5 As shown, a buffer plate 12 is provided on one side of the fixed plate 9 , the buffer plate 12 is slidably connected to the fixed plate 9 , and a second spring 13 is evenly installed between the buffer plate 12 and the fixed plate 9 .

[0049] The buffer plate 12 provides additional pressure to ensure that the sole of the safety shoe fits tightly with the fixing plate 9, thereby preventing the sole from loosening or falling off during the immersion process and ensuring the stability of the test.

[0050] like Figure 4 , Figure 5 and Figure 6 As shown, the rotating assembly includes a first rotating shaft 17 fixedly mounted on one side of the rotating disk 8, the first rotating shaft 17 is embedded in the interior of the lifting plate 5, a pulley group 18 is mounted on the outer wall of the first rotating shaft 17, a second rotating shaft 19 is mounted on the inner wall of the top of the pulley group 18, one side of the second rotating shaft 19 is connected to a gear 22 through a transmission assembly, a moving plate 23 is arranged on one side of the gear 22, tooth blocks 24 are evenly mounted on the side wall of the moving plate 23, a guide groove 25 is arranged at one end of the moving plate 23, and the guide groove 25 is opened on the inner wall of the moving seat 4.

[0051] The bottom of the guide groove 25 is provided with a curved surface on one side close to the movable plate 23;

[0052] When the safety shoes are taken out from the acid-base solution in the immersion tank 2, the lifting plate 5 moves upward to drive the movement of the moving plate 23. The moving plate 23 is guided by the arc surface at the bottom of the guide groove 25 to slide into the lifting plate 5. The movement of the moving plate 23 drives the movement of the tooth block 24. The movement of the tooth block 24 drives the rotation of the gear 22. When the gear 22 rotates, it drives the second rotating shaft 19 to rotate through the transmission component. When the second rotating shaft 19 rotates, it drives the first rotating shaft 17 to rotate through the pulley group 18. The rotation of the first rotating shaft 17 drives the rotation of the rotating disk 8. The rotation of the rotating disk 8 drives the fixed plate 9 to clamp the safety shoes and turn them 180 degrees, so as to pour out the acid-base solution in the shoe and avoid the solution accumulating in the shoe to affect the subsequent observation and test results. It is not only convenient for observation and evaluation, but also further reduces the risk of operators contacting acid-base solutions.

[0053] like Figure 5 and Figure 6 As shown, the transmission assembly includes a worm wheel 20 fixedly mounted on the outer wall of the second rotating shaft 19 , one side of the worm wheel 20 is meshingly connected with a worm 21 , and the worm 21 is fixedly mounted on the bottom end of the gear 22 .

[0054] When the gear 22 rotates, it drives the worm 21 to rotate, and the rotation of the worm 21 drives the worm wheel 20 to rotate, and the rotation of the worm wheel 20 drives the second rotating shaft 19 to rotate. The transmission through the worm wheel 20 and the worm 21 has self-locking property, so that after the safety shoe is turned over, the shoe mouth is kept downward to prevent rotation due to its own gravity, thereby improving the stability of the device.

[0055] like Figure 6 and Figure 7 As shown, the moving plate 23 is slidably installed inside the lifting plate 5 , and a third spring 26 is provided between the moving plate 23 and the lifting plate 5 .

[0056] When the lifting plate 5 moves upward and the moving plate 23 slides into the lifting plate 5 through the guide groove 25, the third spring 26 is deformed by force to store elastic potential energy;

[0057] When the lifting plate 5 moves downward and the moving plate 23 moves to the bottom of the guide groove 25 , the elastic potential energy is released by the third spring 26 to move the moving plate 23 back to its original position.

[0058] like Figure 7 As shown, the inner wall of the gear block 24 is fixedly connected with a third rotating shaft 27 , and the third rotating shaft 27 is rotatably mounted inside the moving plate 23 .

[0059] The interior of the movable plate 23 is provided with a slide groove for the gear block 24 to rotate;

[0060] The side of the gear block 24 away from the worm gear 20 is inclined;

[0061] When the moving plate 23 moves to reset, the inclined surface of the tooth block 24 contacts the gear 22 and is forced to rotate into the moving plate 23. At this time, the gear 22 does not rotate, so that the rotating disk 8 does not turn over.

[0062] like Figure 7 As shown, a torsion spring 28 is installed on the outer wall of the third rotating shaft 27 .

[0063] When the tooth block 24 contacts the gear 22 and is forced to move into the moving plate 23, the torsion spring 28 deforms to store elastic potential energy;

[0064] When the tooth block 24 is separated from the gear 22, the elastic potential energy is released by the torsion spring 28 to move the tooth block 24 back to its original position.

[0065] like Figure 1 and Figure 2 As shown, a guide plate 29 is fixedly installed at the top of the observation slot 3, and two guide plates 29 are symmetrically arranged.

[0066] When the movable seat 4 moves to one side of the observation slot 3 and the safety shoes need to be placed in the observation slot 3, the lifting plate 5 moves downward to drive the rotating disk 8 to move downward, and the movement of the rotating disk 8 drives the movement of the fixed plate 9. When the bottom of the fixed plate 9 contacts the top of the guide plate 29, it is forced to open outward to loosen the safety shoes.

[0067] A testing method for a safety shoe anti-corrosion testing device comprises the following steps:

[0068] S1: First, a quantitatively proportioned acid-base solution is placed in the soaking tank 2, and then the two fixing plates 9 are pulled to the side away from the rotating disk 8, and the sole of the safety shoe is placed right between the two fixing plates 9, and the two fixing plates 9 are fixed inwardly to fix the safety shoe by the elastic force of the first spring 11;

[0069] S2: Then the motor 7 is started by controlling the PLC. When the motor 7 is started, the first threaded rod 6 is driven to rotate. The rotation of the first threaded rod 6 drives the movement of the lifting plate 5. The movement of the lifting plate 5 drives the movement of the rotating disk 8. The movement of the rotating disk 8 drives the movement of the fixed plate 9, so that the fixed plate 9 clamps the safety shoes and immerses them in the acid and alkali solution in the immersion tank 2;

[0070] S3: After soaking, the motor 7 is started to remove the safety shoes from the acid and alkali solution by clamping the two fixing plates 9;

[0071] S4: At the same time, the movement of the lifting plate 5 drives the movement of the moving plate 23, and the moving plate 23 is guided by the arc surface at the bottom of the guide groove 25 so that the moving plate 23 slides into the lifting plate 5, and the movement of the moving plate 23 drives the movement of the tooth block 24, and the movement of the tooth block 24 drives the rotation of the gear 22, and the rotation of the gear 22 drives the rotation of the worm 21, and the rotation of the worm 21 drives the rotation of the worm wheel 20, and the rotation of the worm wheel 20 drives the second rotating shaft 19 to rotate, and when the second rotating shaft 19 rotates, it drives the first rotating shaft 17 to rotate through the pulley group 18, and the rotation of the first rotating shaft 17 drives the rotation of the rotating disk 8, and when the rotating disk 8 rotates, it drives the fixed plate 9 to clamp the safety shoes and turn 180 degrees to pour out the acid and alkali solutions in the shoes;

[0072] S5: After the safety shoes are taken out of the immersion tank 2, the motor 15 is started by the PLC control, and the start of the motor 15 drives the rotation of the second threaded rod 14, and the rotation of the second threaded rod 14 drives the movement of the moving seat 4, and the movement of the moving seat 4 drives the movement of the lifting plate 5, and the movement of the lifting plate 5 drives the movement of the rotating disk 8, so that the safety shoes move from the top of the immersion tank 2 to the top of the observation tank 3;

[0073] S6: Then the motor 7 is controlled to start to move the lifting plate 5 downward, and the lifting plate 5 moves downward to drive the rotating disk 8 to move downward, and the movement of the rotating disk 8 drives the movement of the fixed plate 9. When the bottom of the fixed plate 9 contacts the top of the guide plate 29, it is forced to open outward, loosening the safety shoes, and the safety shoes fall on the top of the filter screen 16, which is convenient for observation.

[0074] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.

S3: After soaking, the motor (7) is started to remove the safety shoes from the acid-base solution by clamping the two fixing plates (9); S4: At the same time, the movement of the lifting plate (5) drives the movement of the moving plate (23), and the moving plate (23) is guided by the arc surface at the bottom of the guide groove (25) so that the moving plate (23) slides into the lifting plate (5), and the movement of the moving plate (23) drives the movement of the tooth block (24), and the movement of the tooth block (24) drives the rotation of the gear (22), and the rotation of the gear (22) drives the rotation of the worm (21), and the rotation of the worm (21) drives the rotation of the worm wheel (20), and the rotation of the worm wheel (20) drives the second rotating shaft (19) to rotate, and when the second rotating shaft (19) rotates, it drives the first rotating shaft (17) to rotate through the pulley group (18), and the rotation of the first rotating shaft (17) drives the rotation of the rotating disk (8), and when the rotating disk (8) rotates, it drives the fixed plate (9) to turn the safety shoes held by the fixed plate (9) by 180 degrees, so as to pour out the acid and alkali solution in the shoes; S5: After the safety shoes are taken out of the soaking tank (2), the motor (15) is started by controlling the PLC. The start of the motor (15) drives the second threaded rod (14) to rotate. The rotation of the second threaded rod (14) drives the movement of the movable seat (4). The movement of the movable seat (4) drives the movement of the lifting plate (5). The movement of the lifting plate (5) drives the movement of the rotating disk (8), so that the safety shoes move from the top of the soaking tank (2) to the top of the observation tank (3). S6: Then the motor (7) is controlled to start and move the lifting plate (5) downward. The lifting plate (5) moves downward and drives the rotating disk (8) to move downward. The movement of the rotating disk (8) drives the fixed plate (9) to move. When the bottom of the fixed plate (9) contacts the top of the guide plate (29), the fixed plate (9) is forced to open outward, loosening the safety shoes. The safety shoes fall on the top of the filter screen (16) to facilitate observation.
