Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Please refer to Figures 1 - 5 , the present utility model provides a technical solution:

[0027] A gearbox sealing detection device, including a detection box 1, a box door 2 is hinged on the outer surface of the detection box 1, a connecting frame 9 is arranged inside the detection box 1, and a gearbox body 3 is arranged above the connecting frame 9. It also includes:

[0028] A detection component, which is located on the outer surface of the detection box 1 and is used for detecting the sealing performance of the gearbox body 3;

[0029] A sealing component, which is located between the detection box 1 and the box door 2 and is used for hermetically connecting the box door 2 and the detection box 1 to provide conditions for the detection of the gearbox body 3;

[0030] A disassembly and assembly component, which is located between the detection box 1 and the connecting frame 9 and facilitates the installation and disassembly of the connecting frame 9. The digital display pressure gauge 8 wirelessly receives data and displays the current air pressure value for the operator to observe. If the air pressure in the detection box 1 remains stable and does not decrease significantly within a certain period of time, it indicates that the sealing performance of the gearbox body 3 is good and there is no leakage. If the air pressure drops significantly, it indicates that there is a leakage in the gearbox body 3.

[0031] Further, the detection component includes an air supply pump 4, an air inlet pipe 5, an air outlet pipe 6, and a regulating valve 7. The top of the detection box 1 is fixedly connected with the air inlet pipe 5 and the air outlet pipe 6. Regulating valves 7 are fixedly installed on the outer surfaces of the air inlet pipe 5 and the air outlet pipe 6. The air supply pump 4 is fixedly installed on the outer surface of the detection box 1, and the air supply pump 4 is fixedly installed with the air inlet pipe 5. Start the air supply pump 4, send a certain amount of gas into the detection box 1 through the air inlet pipe 5, and at the same time close the regulating valve 7 on the air inlet pipe 5 to prevent gas from flowing back.

[0032] Further, a pressure sensor 15 is fixedly installed on the inner wall of the detection box 1, a digital display pressure gauge 8 is fixedly installed on the outer surface of the detection box 1, and the digital display pressure gauge 8 is wirelessly connected to the pressure sensor 15. The pressure sensor 15 installed on the inner wall of the detection box 1 monitors the air pressure change in the box in real time and transmits the data to the external digital display pressure gauge 8. The pressure sensor 15 is of the FSTX800 model, and the digital display pressure gauge 8 is of the MIK-Y290 model.

[0033] Further, the sealing component includes a clamping block 10, a clamping groove 11, and a sealing gasket 12. The sealing gasket 12 is fixedly connected to the outer surface of the box door 2, the clamping block 10 is fixedly connected to the outer surface of the sealing gasket 12, a clamping groove 11 is opened on the front outer surface of the detection box 1, the clamping block 10 is inserted into the clamping groove 11, and the sealing gasket 12 is movably connected to the front outer surface of the detection box 1. A handle is fixedly installed on the outer surface of the box door 2. Close the box door 2, the sealing gasket 12 on the outer surface of the box door 2 contacts the front outer surface of the detection box 1, and is inserted into the clamping groove 11 on the front side of the detection box 1 through the clamping block 10 to form a preliminary seal. The sealing gasket 12 ensures the sealing performance between the box door 2 and the detection box 1 and provides necessary conditions for subsequent sealing detection.

[0034] Furthermore, two symmetrically distributed rectangular grooves 13 are formed in the inner wall of the bottom of the detection box 1, two insertion holes 14 are formed in each of the two gearbox bodies 3, and the clamping columns 16 are inserted into the corresponding insertion holes 14.

[0035] Furthermore, the disassembly and assembly component includes clamping columns 16, connection blocks 17, a housing 18 and a telescopic spring 19. Two symmetrically distributed connection blocks 17 are fixedly connected to the bottom of the connection frame 9. Two clamping columns 16 are movably connected to the inside of each of the two connection blocks 17. The four clamping columns 16 are movably inserted into the corresponding insertion holes 14. Four symmetrically distributed housings 18 are fixedly connected to the top of the connection frame 9. The four housings 18 are movably connected to the corresponding clamping columns 16. Telescopic springs 19 are wound around the outer surfaces of the four clamping columns 16. The telescopic springs 19 are located inside the corresponding housings 18. During the sliding of the connection blocks 17, the clamping columns 16 move upward to compress the telescopic springs 19 located inside the housings 18, so that the bottom of the clamping columns 16 contacts the rectangular grooves 13. When the clamping columns 16 move with the movement of the connection blocks 17 and reach above the insertion holes 14, the telescopic springs 19 reset without force extrusion, so that the clamping columns 16 move downward into the insertion holes 14, and the connection frame 9 is connected to the inner wall of the detection box 1.

[0036] Furthermore, the two connection blocks 17 are slidably connected to the corresponding rectangular grooves 13, and the connection frame 9 is slidably connected to the rectangular grooves 13 at the bottom of the detection box 1 through the connection blocks 17 at its bottom.

[0037] Working principle: When the staff needs to use the gear box sealing detection device, the gear box body 3 to be detected is placed on the connecting frame 9 in the detection box 1. The connecting frame 9 is slidably connected to the rectangular groove 13 at the bottom of the detection box 1 through the connecting block 17 at the bottom to ensure stability and easy positioning. When operating the connecting frame 9 to slide, the plug-in hole 14 located on the outside of the detection box 1 is between the two clamping columns 16, so that the two clamping columns 16 can be plugged into the corresponding plug-in holes 14. During the sliding process of the connecting block 17, the clamping column 16 moves up to squeeze the telescopic spring 19 located in the housing 18, so that the bottom of the clamping column 16 is in contact with the rectangular groove 13. The connecting block 17 moves the clamping column 16 to the top of the plug hole 14, and the telescopic spring 19 is reset without force extrusion, so that the clamping column 16 moves down to the plug hole 14, and the connecting frame 9 is connected to the inner wall of the detection box 1. The connecting frame 9 is installed in the detection box 1 so that the gear box body 3 is located in the detection box 1. The box door 2 is closed, and the sealing gasket 12 on the outer surface of the box door 2 contacts the outer surface of the front side of the detection box 1, and is plugged into the clamping groove 11 on the front side of the detection box 1 through the clamping block 10 to form a preliminary seal. The sealing gasket 12 ensures the sealing between the box door 2 and the detection box 1. The subsequent sealing test provides necessary conditions, starts the air pump 4, and feeds a certain amount of gas into the test box 1 through the air inlet pipe 5, and at the same time closes the regulating valve 7 on the air inlet pipe 5 to prevent gas backflow. At this time, the air pressure inside the test box 1 gradually increases, and the pressure sensor 15 installed on the inner wall of the test box 1 monitors the air pressure changes in the box in real time, and transmits the data to the external digital pressure gauge 8. The digital pressure gauge 8 wirelessly receives data and displays the current air pressure value for the operator to observe. If the air pressure in the test box 1 remains stable within a certain period of time without obvious decline, it means that the sealing performance of the gear box body 3 is good and there is no leakage. If the air pressure drops significantly, it means that there is a leak in the gear box body 3, which requires further inspection and maintenance. After the inspection is completed, open the regulating valve 7 on the air outlet pipe 6 to release the gas in the inspection box 1 to restore the air pressure to a normal level. Open the box door 2 by the handle. If the gear box body 3 has poor sealing, negative pressure will appear inside it, and oil will leak out. Pull the clamping column 16 upward so that the clamping column 16 is disengaged from the plug-in hole 14, thereby realizing the rapid separation of the connecting frame 9 and the gear box body 3. When the new gear box body 3 is subsequently inspected, the connecting frame 9 that has leaked oil can be cleaned, thereby improving the inspection efficiency.
